long-termgrowthstrategy.jpg

In 1999, the Company had been running commercials for nearly a decade, but its brand awareness was hovering at about 10%. An innovative marketing campaign with something unique and memorable that would build brand awareness was needed. The Aflac Duck’s first commercial in the U.S., “Park Bench,” aired on January 1, 2000 and taught consumers how to pronounce “Aflac.” The Aflac Duck made his international debut in Japan in 2003. In the two decades since his U.S. debut, the Aflac Duck has become one of 1934 as amended (the Exchange Act). the most familiar advertising icons in the world, appearing in several commercials and countless print ads in both the U.S. and Japan. Today, the Aflac Duck is a helpmate who increases brand knowledge and connection.

General DescriptionREPORTING SEGMENTS

The Company's insurance business consists of two reporting segments: Aflac Incorporated was incorporatedJapan and Aflac U.S. The Parent Company’s primary insurance subsidiaries are Aflac Life Insurance Japan Ltd. in 1973 under the laws of the state of Georgia. Aflac Incorporated is a general business holding companyJapan (Aflac Japan) and acts as a management company, overseeing the operations of its subsidiaries by providing management services and making capital available. Its principal business is voluntary supplemental and life insurance, which is marketed and administered through its subsidiary, American Family Life Assurance Company of Columbus (Aflac), which operates in the United States (Aflac U.S.) and as a branch in Japan (Aflac Japan). Most of Aflac's policies are individually underwritten and marketed through independent agents. Aflac U.S. markets and administers group products through; Continental American Insurance Company (CAIC), branded as Aflac Group Insurance. The Company's insurance operationsInsurance (AGI); American Family Life Assurance Company of New York (Aflac New York) and Tier One Insurance Company (TOIC) in the United StatesU.S. (collectively, Aflac U.S.).

Aflac Japan is the principal contributor to the Parent Company’s consolidated earnings. Aflac Japan's revenues, including realized gains and losses on its branch in Japan service the two marketsinvestment portfolio, accounted for 69% of the Company's insurance business.
Ontotal revenues in 2019, compared with 70% in both 2018 and 2017. The percentage of the Company's total assets attributable to Aflac Japan was 83% and 84% at December 2, 2016, the Company publicly announced that it will pursue the31, 2019 and 2018, respectively. The conversion of Aflac Japan from a branch structure to a subsidiary structure within April 2018 did not affect the subsidiary incorporated as a “Kabushiki Kaisha.” While the branch structure remains an acceptable legal form, the subsidiary structure has emerged as the more prevalent structure for both domestic and foreign companies operating in Japan. In addition, emerging global regulatory standards generally favor the subsidiary structure for foreign insurance and financial service companies. The adoption of this new organizational framework is expected to be tax-neutral and not to have a material impact on the daily operations of either Aflac Japan or Aflac U.S. as a result of this conversion. In addition, the Company expects to obtain enhanced flexibility in capital management and business development as a result of the conversion. The Company anticipates completion of the conversion as early as April 1, 2018. As an interim step, effectiveCompany's segment reporting structure.

The Company is authorized to conduct insurance business in all 50 states, the District of Columbia, several U.S. territories and Japan.

Reporting Segments
Aflac's insurance business consists of two reporting segments:respective Aflac Japan and Aflac U.S. business segments.

In November 2019, the Company acquired Argus Holdings, LLC and its subsidiary Argus Dental & Vision, Inc. (Argus), a benefits management organization and national network dental and vision company, which provides a platform for Aflac Japan, which currently operates as a branchDental and Vision. The Company paid $75 million at closing and made an additional commitment of Aflac,up to $21 million in contingent consideration payable over three years based on the achievement by Argus of certain performance targets. Argus is the principal contributoran addition to the Parent Company’sAflac U.S. segment.

years ended December 31, 2019 and 2018. For information on the Company's results of operations and financial information by segment, see MD&AItem 7. Management Discussion and Analysis (MD&A) and Note 2 of the Notes to the Consolidated Financial Statements in this report.

AFLAC JAPAN

Aflac Japan is the largest insurer in Japan in terms of cancer and medical (third sector insurance products) policies in force. As of December 31, 2019, Aflac Japan exceeded 24 million individual policies in force in Japan. Aflac Japan continued to be the number one seller of cancer insurance policies in Japan throughout 2019, with more than 15 million cancer policies in force as of December 31, 2019.

Insurance Products

Aflac Japan's third sector insurance products are designed to help consumers pay for medical and nonmedical costs that are not reimbursed under Japan's national health insurance system. Changes in Japan's economy and an aging population have put increasing pressure on Japan's national health care system. As a result, more costs have been shifted to Japanese consumers, who in turn have become increasingly interested in insurance products that help them manage those costs. Aflac Japan has responded to this consumer need by enhancing existing products and developing new products. The focus at Aflac Japan remains on maintaining leadership in third sector insurance products that are less interest rate sensitive and have strong and stable margins. At the same time, Aflac Japan complements this core business with similarly profitable first sector protection products as outlined below.

THIRD SECTOR INSURANCEFIRST SECTOR INSURANCE
Life insurance products include:
Cancer

WAYS

GIFT
Cancer InsuranceAflac Japan pioneered the cancer insurance market in Japan in 1974, and remains the number one provider of cancer insurance in Japan today. Aflac Japan's cancer insurance products provide a lump-sum benefit upon initial diagnosis of cancer and fixed daily benefits for subsequent hospitalization and outpatient treatments due to cancer, as well as cancer-related surgical and convalescent care benefits.


3





Medical Insurance Aflac Japan's medical insurance products provide benefits for hospitalization, surgeries and outpatient treatment of various illnesses, as well as lump sum benefits related to three critical illnesses: cancer, heart attack, and stroke.

Income Support Insurance Aflac Japan's Income Support Insurance provides fixed-benefit amounts in the event that a policyholder is unable to work due to significant illness or injury and was developed to supplement the disability coverage within Japan’s social security system.

Whole Life Aflac Japan launched Prepare Smart Whole-Life Insurance in 2018, a whole life insurance product with low cash surrender value, which offers non-smoking policyholders further discounted premiums, and it provides beneficiaries, typically a designated family member, with a pre-determined benefit payment upon the death of the insured.

GIFT GIFT is a term life insurance product that provides a designated family member with a fixed amount of money every month upon a breadwinner’s death or serious disability as family support.

WAYS and Child Endowment Beginning in 2013, Aflac Japan began to curtail sales of WAYS and Child Endowment, first sector savings-type products, due to persistent low interest rates in Japan and, in particular, the relatively large capital commitment required by such products and their lower profitability, in such an environment.

Distribution Channels

Traditional Sales ChannelThis distribution channel includes individual agencies, independent corporate agencies and affiliated corporate agencies. Aflac Japan was represented by more than 9,000 sales agencies at the end of 2019, with more than 109,000 licensed sales associates employed by those agencies, including individual agencies.

BanksConsumers in Japan rely on banks to provide not only traditional bank services, but also as one key source to provide insurance solutions and other services. By the end of 2019, Aflac Japan had agreements with approximately 90% of the total number of banks in Japan to sell its products.

Dai-ichi LifeAflac Japan's alliance with Dai-ichi Life was launched in 2001, and approximately 40,000 Dai-ichi Life representatives offer Aflac's cancer products.

Japan Post GroupAflac Japan's alliance with Japan Post Group was launched in 2008. After the alliance strengthened in 2013, the number of postal outlets of Japan Post Co. Ltd. (JPC) selling Aflac Japan's cancer product increased to more than 20,000 since 2015. Japan Post Insurance Co., Ltd. (JPI) offers Aflac Japan cancer products through its 76 directly managed sales offices. In 2018, the Company’ entered a strategic alliance with Japan Post Holdings Co., Ltd. (Japan Post Holdings), the parent company of Japan Post Co. Ltd (JPC) and Japan Post Insurance Co., Ltd. (JPI). See the "Aflac Japan Segment" subsection of MD&A for more about this alliance.

Daido LifeIn 2013, Aflac Japan and Daido Life Insurance entered into an agreement for Daido to sell Aflac Japan's cancer insurance products specifically to the Hojinkai market, which is an association of small businesses. Currently, Daido also sells Aflac Japan's cancer insurance products to the market in the tax payment association, which is a not-for-profit association for small businesses to support tax related matters.

Competition

The Company competes with other insurance carriers through policyholder service, price, product design and sales efforts, as the number of insurance companies offering stand-alone cancer and medical insurance has more than doubled since the deregulation of the Japan market in 2001. However, based on Aflac Japan's growth of annualized premiums in force and diversified distribution network, the Company does not believe that Aflac Japan's market-leading position has been significantly impacted by increased competition. Furthermore, the Company believes the continued development and maintenance of operating efficiencies will allow Aflac Japan to offer affordable products that appeal to consumers. The Company believes Aflac Japan will remain a leading provider of cancer and medical insurance coverage in Japan, principally due to its experience in the market, well-known brand, low-cost operations, expansive marketing system and product expertise.

Regulation

Financial Services Agency (FSA) The financial and business affairs of Aflac Japan are subject to examination by Japan's FSA. Aflac Japan files annual reports and financial statements for the Japanese insurance operations based on a March 31 fiscal year end, prepared in accordance with Japanese regulatory accounting practices prescribed or permitted by the FSA. Japanese regulatory basis earnings are determined using accounting principles that differ materially from U.S. generally

4





accepted accounting principles (U.S. GAAP). Capital and surplus of Aflac Japan, based on Japanese regulatory accounting practices, was $7.8 billion at December 31, 2019, compared with $6.4 billion at December 31, 2018. Two FSA regulations applicable to Aflac Japan are outlined below.

Privacy and Cybersecurity
With regard to personal information obtained from policyholders, the insured, or others, Aflac Japan is regulated in Japan by the Act on the Protection of Personal Information (APPI) and guidelines issued by FSA and other governmental authorities. The FSA updated its guidelines regarding cybersecurity in October 2018.

FSA Solvency Standard
The FSA maintains a solvency standard, the solvency margin ratio (SMR), which is used by Japanese regulators to monitor the financial strength of insurance companies. As of December 31, 2019, Aflac Japan's SMR was 1,043%, compared with 965% at December 31, 2018. Aflac Japan's SMR is sensitive to interest rate, credit spread and foreign exchange rate changes. See the Liquidity and Capital Resources section of the MD&A for a discussion of measures the Company has taken to mitigate the sensitivity of Aflac Japan's SMR.

Japan Company LawAs abranch of Aflac prior to April 1, 2018, Aflac Japan repatriated a portion of its accumulated earnings, as determined on a Japanese regulatory accounting basis, to Aflac U.S. provided that Aflac Japan had determined that it adequately protected policyholders' interests as measured by its SMR. After the conversion of Aflac Japan to a subsidiary structure on April 1, 2018 and starting in the fourth quarter of 2018, Aflac Japan distributes dividends to the Parent Company. Such dividends are subject to permitted dividend capacity under the Japan Company Law.

Policyholder ProtectionThe Japanese insurance industry has a policyholder protection corporation that provides funds for the policyholders of insolvent insurers. For additional information, see the policyholder protection section of the MD&A.

For additional information regarding Aflac Japan's operations and regulations, see the "Aflac Japan Segment" subsection of MD&A and Notes 2 and 13 of the Notes to the Consolidated Financial Statements in this report.

AFLAC U.S.

The Company designs its U.S. insurance products to provide supplemental coverage for people who already have major medical or primary insurance coverage, as Aflac U.S. insurance policies pay benefits regardless of other insurance. Aflac U.S. products are distributed in the individual and group supplemental insurance markets. Aflac's individual policies are portable, meaning that individuals may retain their full insurance coverage upon separation from employment or affiliation with a group, generally at the same premium. Individual policies are typically guaranteed-renewable for the lifetime of the policyholder (to age 75 for short-term disability policies).

Hospital indemnity products provide policyholders fixed dollar benefits triggered by hospitalization due to accident or sickness. Indemnity benefits for inpatient and outpatient surgeries, as well as various other diagnostic events, are also available. Aflac U.S. also offers a lump sum rider for a range of critical illness events that can be added to its individual accident, short-term disability and hospital indemnity products.

Dental and Vision Insurance Aflac U.S. now offers network dental and vision products on a group basis. Aflac U.S. offers fixed-benefit dental coverage on both an individual and group basis. Aflac U.S. offers Vision NowSM, an individually issued policy which provides benefits for serious eye health conditions and loss of sight as well as coverage for corrective eye materials and exam benefits.

Life (Term and Whole)Aflac U.S. offers term- and whole-life policies on both an individual and group basis.

Distribution Channels

Independent Associates/Career AgentsThe career agent channel in Aflac U.S. focuses on marketing Aflac to the small business market, defined as employers of between three and 99 employees. Sales associates in the U.S. are independent contractors and are paid commissions and other variable compensation based on first-year and renewal premiums from their sales of insurance products.

BrokersThe broker channel of Aflac U.S. focuses on selling to the mid- and large-case market, which is comprised of employers with 100 or more employees and typically an average size of 1,000 employees or more. Brokers in the U.S. are independent contractors and are paid commissions based on first-year and renewal premiums from their sales of insurance products.

Aflac U.S. concentrates on marketing its insurance products at the worksite. This method offers policies to individuals through employment, trade and other associations. Aflac U.S. believes that worksite marketing enables sales associates and brokers to reach a greater number of prospective policyholders and lowers distribution costs, compared with individually marketed business. Aflac U.S. is also expanding its distribution strategy to reach consumers outside of the traditional worksite through digital lead generation.

Competition

Aflac U.S. competes against several supplemental insurance carriers on a national and regional basis. Aflac U.S. believes its policies, premium rates, platforms, value-added services and sales commissions are competitive by product type. Moreover, Aflac U.S. believes that its products are distinct from competitive offerings given its product focus (including features, benefits and claims service model), distribution capabilities and brand awareness. 

Since Aflac products provide an additional level of financial protection for policyholders, the Company believes the increased financial exposure some employees may face creates a favorable opportunity for Aflac U.S. products. However, given the profitability erosion some major medical carriers are facing in their core lines of business, the Company has seen a more competitive landscape as these carriers seek entry into Aflac's supplemental product segments and leverage their core benefit offerings by bundling and discounting products in order to gain market share.

One Day PaySM is a claims initiative that Aflac U.S. has focused on to process, approve and pay eligible claims in just one day. The Company believes that this claims practice enhances the Aflac U.S. brand reputation and the trust policyholders have in Aflac, and it helps Aflac stand out from competitors.

Regulation

Insurance RegulationThe Parent Company and its U.S. insurance subsidiaries, Aflac, CAIC, TOIC (Nebraska-domiciled insurance companies) and Aflac New York (a New York-domiciled insurance company) are subject to state regulations in the U.S. as an insurance holding company system. Such regulations generally provide that transactions between companies within the holding company system must be fair and equitable. In addition, transfers of assets among such affiliated companies, certain dividend payments from insurance subsidiaries and certain transactions between companies within the system, including management fees, loans and advances are subject to prior notice to, or approval by, state regulatory authorities. These laws generally require, among other things, the insurance holding company and each insurance company directly owned by the holding company to register with the insurance departments of their respective domiciliary states and to furnish annually financial and other information about the operations of companies within the holding company system.


6





Like all U.S. insurance companies, Aflac, Aflac New York, CAIC and TOIC are subject to regulation and supervision in the jurisdictions in which they do business. In general, the insurance laws of the various jurisdictions establish supervisory agencies with broad administrative powers relating to, among other things:

granting and revoking licenses to transact business
regulating trade and claims practices
licensing of insurance agents and brokers
approval of policy forms and premium rates
standards of solvency and maintenance of specified policy benefit reserves and minimum loss ratio requirements
capital requirements
limitations on dividends to shareholders
the nature of and limitations on investments
deposits of securities for the benefit of policyholders
filing of financial statements prepared in accordance with statutory insurance accounting practices prescribed or permitted by regulatory authorities
periodic examinations of the market conduct, financial, and other affairs of insurance companies

The insurance laws of Nebraska that govern Aflac's activities provide that the acquisition or change of “control” of a domestic insurer or of any person that controls a domestic insurer cannot be consummated without the prior approval of the Nebraska Department of Insurance (NDOI). A person seeking to acquire control, directly or indirectly, of a domestic insurance company or of any person controlling a domestic insurance company (in the case of Aflac, CAIC and TOIC, the Parent Company) must generally file with the NDOI an application for change of control containing certain information required by statute and published regulations and provide a copy to Aflac. In Nebraska, control is generally presumed to exist if any person, directly or indirectly, acquires 10% or more of an insurance company or of any other person or entity controlling the insurance company. The 10% presumption is not conclusive and control may be found to exist at less than 10%. Similar laws apply in New York, the domiciliary jurisdiction of Aflac's New York insurance subsidiary.

State insurance departments conduct periodic examinations of the books and records, financial reporting, policy filings and market conduct of insurance companies domiciled in their states, generally once every three to five years. Examinations are generally carried out in cooperation with the insurance departments of other states under guidelines promulgated by the National Association of Insurance Commissioners (NAIC). In 2016, full-scope, risk-focused financial examinations were conducted by the NDOI, New York Department of Financial Services (NYDFS), and the South Carolina Department of Insurance (SCDOI) on their state domiciled insurance entities Aflac, Aflac New York, and CAIC, respectively. There were no material findings contained in the final exam reports. CAIC redomiciled to Nebraska as of December 2016 and TOIC redomiciled to Nebraska effective March 11, 2019. The NDOI and NYDFS are scheduled to conduct a full-scope comprehensive financial examination covering years 2016-2019 in 2020.

NAIC Risk-Based CapitalThe NAIC continually reviews regulatory matters, such as risk-based capital (RBC) modernization, group capital calculations, liquidity risk assessment and principle-based reserving. The NAIC has adopted a valuation manual containing a principle-based approach to calculation of life insurance reserves. The valuation manual became effective January 1, 2017. There is a three-year transition period, beginning January 1, 2017, during which companies can choose on a product by product basis to implement principle-based reserving for new business. The Company anticipates that the adoption of this manual will not cause a material impact on the statutory reserves of Aflac, Aflac New York, CAIC or TOIC. The NAIC uses an RBC formula relating to insurance risk, business risk, asset risk and interest rate risk to facilitate identification by insurance regulators of inadequately capitalized insurance companies based upon the types and mix of risk inherent in the insurer's operations. The formulas for determining the amount of RBC specify various weighting factors that are applied to financial balances or various levels of activity based on the perceived degree of risk. Regulatory compliance is determined by a ratio of a company's regulatory total adjusted capital to its authorized control level RBC as defined by the NAIC. Companies below specific trigger points or ratios are classified within certain levels, each of which requires specified corrective action. The levels are company action, regulatory action, authorized control, and mandatory control. As of December 31, 2019, based on year-end statutory accounting results, Aflac's company action level RBC ratio was 539%. The 2018 RBC as filed is lower than Aflac U.S. stand-alone RBC due to the inclusion of Aflac Japan for the first quarter of 2018. The RBC charge reflects the business risk without any total adjusted capital (TAC). Aflac's NAIC RBC ratio remains high and reflects a very strong capital and surplus position.

Guaranty Association and Similar ArrangementsUnder state insurance guaranty association laws and similar laws in international jurisdictions, the Company is subject to assessments, based on the share of business the Company writes in the relevant jurisdiction, for certain obligations of insolvent insurance companies to policyholders and claimants. In the U.S., some states permit member insurers to recover assessments paid through full or partial premium tax offsets. The Company's policy is to accrue assessments when the entity for which the insolvency relates has met its state of domicile's statutory

7





definition of insolvency, the amount of the loss is reasonably estimable and the related premium upon which the assessment is based is written. In most states, the definition is met with a declaration of financial insolvency by a court of competent jurisdiction.

Federal InitiativesFederal legislation and administrative policies in several areas, including health care reform legislation, financial services reform legislation, securities regulation, pension regulation, privacy, tort reform legislation and taxation, can significantly and adversely affect insurance companies. Federal regulations applicable to Aflac U.S. are outlined below.

Affordable Care Act (ACA)
The ACA, federal health care reform legislation, gave the U.S. federal government direct regulatory authority over the business of health insurance. The reform included major changes to the U.S. health care insurance marketplace. The ACA, as enacted, does not require material changes in the design of the Company's insurance products. However, indirect consequences of the legislation and regulations could present challenges that could potentially have an impact on the Company's sales model, financial condition and results of operations. The U.S. Congress has considered and may continue to consider legislation that would repeal and replace key provisions of the ACA. There can be no assurance that any legislation affecting the ACA will be passed by Congress, nor as to the ultimate timing or provisions of any such legislation, nor as to the effect of any such legislation on the design or marketability of the Company's insurance products. Further, certain provisions of the ACA have been and may continue to be subject to challenge through litigation, the ultimate effects of which on the ACA are uncertain.

Dodd-Frank Act
Title VII of the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 (Dodd-Frank) and regulations issued thereunder, in particular rules to require central clearing for certain types of derivatives, may have an impact on the Company's derivative activity, including activity on behalf of Aflac Japan. In addition, in 2015 and 2016, six U.S. financial regulators, including the U.S. Commodity Futures Trading Commission (CFTC), issued final rules regarding the exchange of initial margin (IM) and variation margin (VM) for uncleared swaps that impose greater obligations on swap dealers regarding uncleared swaps with certain counterparties, such as the Company. The requirements of such rules with respect to IM are currently being phased in and will be fully implemented by September 1, 2020, although an extension to September 1, 2021 is expected for covered entities with an aggregate average notional amount below $50 billion. The margin requirements are expected to result in more stringent collateral requirements and to affect other aspects of the Company's derivative activity.

The Dodd-Frank Act also established a Federal Insurance Office (FIO) under the U.S. Treasury Department to monitor all aspects of the insurance industry and of lines of business other than certain health insurance, certain long-term care insurance and crop insurance. Traditionally, U.S. insurance companies have been regulated primarily by state insurance departments. The FIO does not directly regulate the insurance industry, but under Dodd-Frank it has the power to preempt state insurance regulations that are inconsistent with international agreements reached by the federal government, subject to certain requirements and restrictions. The FIO and certain federal agencies must achieve consensus positions with the state insurance regulators when taking positions on insurance proposals by certain international forums. The President and Congress have stated proposals to reform or repeal certain provisions of the Dodd-Frank Act, some of which have been implemented. The Company cannot predict with any degree of certainty what impact, if any, such proposals might have on Aflac's business, financial condition, or results of operations.

Privacy and Cybersecurity
The collection, maintenance, use, protection, disclosure and disposal of individually identifiable data by the Company's businesses are regulated at the international, federal and state levels. These laws and rules are subject to change by legislation or administrative or judicial interpretation. Various state laws address the unauthorized access and acquisition of personal information and the use and disclosure of individually identifiable health data to the extent they are more restrictive than those contained in the privacy and security provisions in the federal Gramm-Leach-Bliley Act of 1999 (GLBA) and in the Health Insurance Portability and Accountability Act of 1996 (HIPAA). For example, the California Consumer Privacy Act became effective January 1, 2020 and requires businesses to provide California consumers rights to access, delete, and restrict certain uses of their personal information. Under the law, the California Attorney General may not bring an enforcement action prior to July 1, 2020. HIPAA also requires that the Company imposes privacy and security requirements on its business associates (as such term is defined in the HIPAA regulations).

Cybersecurity also continues to be an area of evolving focus for U.S. legislation and regulatory activity. In March 2017, new cybersecurity regulation issued by the NYDFS went into effect that requires covered entities, including Aflac New York, to maintain an information security program meeting certain security, data disposal, audit, activity

8





monitoring, and data encryption requirements. In October 2017, the NAIC adopted an Insurance Data Security Model Law that may be adopted in whole or in part by U.S. states in which the Company’s subsidiaries are licensed. Other states have adopted and, the Company expects, will continue to pass legislation and issue regulations related to cybersecurity. The Company anticipates, assesses and if necessary modifies its information security program to accommodate such changes.

ITEM 1A. RISK FACTORS
The Company faces a wide range of risks, and its continued success depends on its ability to identify, prioritize and appropriately manage enterprise risk exposures. Readers should carefully consider each of the following risks and all of the other information set forth in this Form 10-K. These risks and other factors may affect forward-looking statements, including those in this document or made by the Company elsewhere, such as in earnings release webcasts, investor conference presentations or press releases. The risks and uncertainties described herein may not be the only ones facing the Company. Additional risks and uncertainties not presently known to the Company or that the Company currently believes to be immaterial may also adversely affect its business. If any of the following risks and uncertainties develops into actual events, there could be a material impact on the Company.
Sales of the Company's products and services are dependent on its ability to attract, retain and support a network of qualified sales associates, brokers and employees in the U.S. and sales associates and other distribution partners in Japan.

The Company's sales, results of operations and financial condition could be materially adversely affected if its sales networks deteriorate or if the Company does not adequately provide support, training and education for its existing network of sales associates, brokers, other distribution partners and employees. In the U.S., competition exists for sales associates and brokers with demonstrated ability. In Japan, the Company's sales results are dependent upon its relationship with sales associates and other distribution partners, including its strategic partner, Japan Post.

The Company competes with other insurers and financial institutions primarily on the basis of its products, compensation, support services and financial rating. The Company's sales associates, brokers and other distribution partners are independent contractors and may sell products of its competitors. If the Company's competitors offer products that are more attractive, or pay higher commissions than the Company does, any or all of these distribution partners may concentrate their efforts on selling the Company's competitors' products instead of the Company's. In addition to the Company's commissioned sales force in the U.S., Aflac has expanded its sales leadership team to include a salaried sales force of over 200 market directors and broker sales professionals. The Company's inability to attract and retain qualified sales associates, brokers and other distribution partners, including its alliance partners in Japan, could have a material adverse effect on the Company's sales, results of operations and financial condition.

Additionally, as the Japan and U.S. employment markets continue to evolve, there is risk that the Company's practices regarding attracting, developing, and retaining employees may not be fully effective. Failure to successfully meet and maintain sufficient levels of employees may diminish the Company's ability to achieve its financial and compliance objectives, both of which are time consuming and personnel-intensive.

For more information on the strategic partnership with Japan Post, see the risk factor below entitled, " Events related to the ongoing Japan Post investigation and other matters regarding sales of Japan Post Insurance products could negatively impact the Company’s sales and results of operations."

Events related to the ongoing Japan Post investigation and other matters regarding sales of Japan Post Insurance products could negatively impact the Company’s sales and results of operations

As previously disclosed, in the second half of 2019 and the first quarter of 2020 there have been news reports and public comments regarding improper sales practices relating to sales of JPI products by JPI and JPC, each an affiliate of Japan Post Holdings (together with JPI and JPC, the Japan Post Group). JPC and JPI are important distribution and alliance partners of the Company, which in 2018 collectively accounted for approximately 25% of Aflac Japan’s third sector sales. On July 24, 2019, after such news reports and other public comments, the Japan Post Group announced that they had established a Special Investigative Committee comprised of independent former prosecutors to determine whether JPC and JPI sales practices with respect to JPI products had caused disadvantages to customers holding such policies that were not otherwise the result of honoring such customers’ intentions.

On December 18, 2019, the Japan Post Group issued a release discussing results of the investigation and stating that JPI had identified a number of cases involving potential violation of laws and regulations or internal rules. On the same date, the Japan Post Group stated that it would continue the investigation with a goal of completing it by March 2020. On December 27, 2019, the Japanese FSA issued three-month business suspension orders to JPC and JPI for the sale of JPI insurance products, and the Japan Ministry of Internal Affairs and Communications also issued a three-month business suspension order to JPC for the sale of JPI insurance products. Also on December 27, 2019, the Japan Post Group announced the resignation of the chief executives of Japan Post Holdings, JPC and JPI, to be effective January 5, 2020. On January 31,

11



2020, the Japan Post Group announced that its internal investigation had been expanded to additional policyholders and the investigation would continue with a goal of completing it by the end of June 2020. The Japan Post Group stated they could not comment on the expected timing for it to re-initiate sales of JPI insurance products.

Notwithstanding the JPI investigation and the three-month suspension orders promulgated by the FSA and the Japan Ministry of Internal Affairs and Communications, the sale of Aflac Japan cancer policies has continued through JPC and JPI. However, while the sale of Aflac Japan cancer insurance products is not within the scope of the suspension orders, beginning in August 2019 the Company has experienced a material decrease of sales in the Japan Post Group channel. This decline has continued into 2020. The Company believes that sales of Aflac Japan cancer insurance through JPC and JPI are unlikely to return to 2018 levels in the near term. It is uncertain what long-term effect these developments will have on the Company’s results of operations or financial condition, but any such effects could be material. See the "Aflac Japan Segment" subsection of Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations.

Competition could adversely affect the Company's ability to increase or maintain its market share or profitability.

The Company operates in a competitive environment and in an industry that is subject to ongoing changes from market pressures brought about by customer demands, legislative reform, marketing practices and changes to health care and health insurance delivery. These factors require the Company to anticipate market trends and make changes to differentiate the Company's products and services from those of its competitors. The Company also faces the potential of competition from existing or new companies in the U.S. and Japan that have not historically been active in the supplemental health insurance industry, but some of which have greater financial, marketing and management resources than the Company does. Further, some of these potential competitors could introduce new means of product development and delivery that disrupt the Company’s business model. Failure to anticipate market trends and/or to differentiate the Company's products and services can affect the Company's ability to retain or grow profitable lines of business. Further, as employers and brokers are increasingly requesting a full-suite of products from one insurance provider, a failure to react and adapt to these demands could result in decreased sales or market share.

The insurance market is undergoing rapid changes with frequent introductions of new technology-driven products and services. The Company's future success will depend, in part, on its ability to keep pace with the technological changes and to use technology to satisfy and grow customer demand for the Company's products and services and to create additional efficiencies in its operations. The Company expects that it will need to continue making substantial investments in its technology and information systems to compete effectively and to stay current with technological changes. The Company may not be able to effectively implement new technology-driven products and services or be successful in marketing these products and services to its customers. A failure to meet evolving customer demands through innovative product development, effective distribution channels, and continuous investment in the Company's technology could result in lower revenues and less favorable policy terms and conditions, which could adversely affect the Company's operating results. As a result, the Company's ability to effectively compete to retain or acquire new business may be impaired, and its business, financial condition or results of operations may be adversely affected.

If future policy benefits, claims or expenses exceed those anticipated in establishing premiums and reserves, the Company's financial results would be adversely affected.

The Company establishes premiums for many of its policies on assumptions for morbidity, mortality, longevity and persistency. The Company also establishes and carries, as a liability, reserves based on estimates of how much will be required to pay for future benefits and claims on its policies. The Company calculates these reserves using various assumptions and estimates, including premiums the Company will receive over the assumed life of the policy; the timing, frequency and severity of the events covered by the insurance policy; and the investment returns on the assets the Company purchases with a portion of its net cash flow from operations.

The assumptions and estimates that the Company uses in establishing premiums and reserves depend on the Company's judgment regarding the likelihood of future events and are inherently uncertain. Many factors can cause actual outcomes to deviate from these assumptions and estimates, such as changes in incidence rates, economic conditions, changes in government healthcare policy, advances in medical technology, changes in treatment patterns, and changes in average lifespan. Accordingly, the Company cannot determine with precision the ultimate amounts that it will pay for, or the timing of payment of, actual benefits and claims or whether the assets supporting the policy liabilities will grow to the level the Company assumes prior to payment of benefits or claims. If the Company's actual experience is different from its assumptions or estimates, the Company's reserves may prove inadequate. As a result, the Company would incur a charge to earnings in the period in which it determines such a shortfall exists, which could have a material adverse effect on the Company's business, results of operations and financial condition.


12



Generally, lower mortality decreases the profitability of third sector products in Japan, as more policyholders will survive into ages where they have a higher rate of claim incidence. This assumption can impact pricing and reserving.  For instance, Japan FSA periodically requires updates to their Standard mortality tables for FSA reserves. An update to the Standard mortality tables was performed in April 2018 applicable to all business issued after that date. For business that is inforce prior to the update, the change in mortality table would not have an impact. For new issues, the updated mortality tables would be included in the Company's reserve assumptions, and slow the emergence of FSA earnings for third sector products and therefore will have an impact on pricing returns. The Company adjusts pricing assumptions as new products are developed to adjust for these mortality assumptions. 

The success of the Company's business depends in part on effective information technology systems and on continuing to develop and implement improvements in technology.

The Company's business depends in large part on its technology systems for interacting with employers, policyholders, sales associates, and brokers, and the Company's business strategy involves providing customers with easy-to-use products to meet their needs and ensuring employees have the technology in place to support those needs. Some of the Company's information technology systems and software are older, legacy-type systems that are less efficient and require an ongoing commitment of significant resources to maintain or upgrade to current standards including adequate business continuity procedures. The Company is in a continual state of upgrading and enhancing its business systems; however, these changes tend to challenge the Company's complex integrated environment. The Company's success is dependent in large part on maintaining or improving the effectiveness of existing systems and continuing to develop and enhance information systems that support its business processes in a cost-efficient manner. If the Company does not maintain the effectiveness of its systems, the Company's operations and reputation could be adversely affected and it could be exposed to litigation as well as to regulatory proceedings and fines or penalties.

Defaults, downgrades, widening credit spreads or other events impairing the value of the fixed maturity securities and loan receivables in the Company's investment portfolio may reduce the Company's earnings and capital position.
The Company is subject to the risk that the issuers and/or guarantors of fixed maturity securities and loan receivables the Company owns may default on principal or interest. A significant portion of the Company's portfolio represents an unsecured obligation of the issuer, including some that may be subordinated to other debt in the issuer’s capital structure. In these cases, many factors can influence the overall creditworthiness of the issuer and ultimately its ability to service and repay the Company's holdings. This can include changes in the global economy, the company's assets, strategy, or management, shifts in the dynamics of the industries in which they compete, their access to additional funding, and the overall health of the credit markets. Factors unique to the Company's securities including contractual protections such as financial covenants or relative position in the issuer's capital structure also influence the value of the Company's holdings.

Most of the Company's investments carry a rating by one or more of the nationally recognized statistical rating organizations (NRSROs or rating agencies). Any change in the rating agencies' approach to evaluating credit and assigning an opinion could negatively impact the fair value of the Company's portfolio. The Company employs a team of credit analysts to monitor the creditworthiness of the issuers in its portfolio. Any credit-related declines in the fair value of positions held in the Company's portfolio believed to be not temporary in nature will negatively impact the Company's net income and capital position through impairment and other credit related losses. These losses would also affect the Company's solvency ratios in the U.S. and Japan. Aflac Japan has certain regulatory accounting requirements for realizing impairments that could be triggered by credit-related losses, which may be different from U.S. GAAP and statutory requirements. These impairment losses could negatively impact Aflac Japan's earnings, and the corresponding dividends and capital deployment.

The Company is also subject to the risk that any collateral providing credit enhancement to the Company's positions could deteriorate. These instruments may include senior secured first lien loans, such as commercial mortgage loans, bank loans, middle market loans, and loan-backed securities where the underlying loan or collateral notes may default on principal, interest, or other payments, causing an adverse change in cash flows to the positions held in the Company's investment portfolio.

The Company is exposed to sovereign credit risk through instruments issued directly by governments and government entities as well as banks and other institutions that rely in part on the strength of the underlying government for their credit quality. In addition to the U.S. and Japan, many governments, especially in Europe, have been subject to rating downgrades due to the need for fiscal and budgetary remediation and structural reforms, reduced economic activity, and investment needed to support banks or other systemically important entities. Additional downgrades or default of the Company's sovereign issuers will have a negative impact on its portfolio and could reduce the Company's earnings and capital.

In addition to the Company's exposure to the underlying fundamental credit strength of the issuers of its fixed maturity securities and the underlying risk of default, the Company is also exposed to the general movement in credit market spreads. A widening of credit spreads could reduce the value of the Company's existing portfolio, create unrealized losses on its investment portfolio, and reduce the Company's adjusted capital position which is used in determining the SMR in Japan. This widening of credit spreads could, however, increase the net investment income on new credit investments. Conversely, a tightening of credit spreads could increase the value of the Company's existing portfolio and create unrealized gains on its investment portfolio. This tightening of credit spreads could also reduce the net investment income available to the Company on new credit investments. Increased market volatility also makes it difficult to value certain of the Company's investment holdings (see the Critical Accounting Estimates section in Item 7, Management's Discussion and Analysis, of this Form 10-K).

For more information regarding credit risk, see the Credit Risk subsection of Item 7A, Quantitative and Qualitative Disclosures about Market Risk, of this Form 10-K.

The Company is exposed to significant interest rate risk, which may adversely affect its results of operations, financial condition and liquidity.
The Company has substantial investment portfolios that support its policy liabilities. Low levels of interest rates on investments experienced in Japan and the U.S. over the last decade have reduced the level of investment income earned by the Company. The Company's overall level of investment income will be negatively impacted in a persistent low-interest-rate environment. While the Company generally seeks to maintain a diversified portfolio of fixed-income investments that reflects the cash flow and duration characteristics of the liabilities it supports, the Company may not be able to fully mitigate the interest rate risk of its assets relative to its liabilities. The Company's exposure to interest rate risk relates primarily to the ability to invest future cash flows to support the interest rate assumption made at the time the Company's products were priced and the related reserving assumptions were established. A sustained decline in interest rates could hinder the Company's ability to earn the returns assumed in the pricing and the reserving for its products at the time they were sold and issued. Due to low interest rates, the Company's ability to earn the returns it expects may also influence the Company's ability to develop and price attractive new products and could impact its overall sales levels. The Company's first sector products are more interest rate sensitive than third sector products. As discussed in Item 1. Business, beginning in 2013, Aflac Japan began to curtail sales of first sector savings-type products due to persistent low interest rates in Japan. The continuing negative interest rate imposed by the Bank of Japan (BoJ) on excess bank reserves could continue to have a negative impact on the distribution and pricing of these products.
A rise in interest rates could improve the Company's ability to earn higher rates of return on future investments, as well as floating rate investments held in its investment portfolio. However, an increase in the differential of short-term U.S. and Japan interest rates would increase the cost of hedging a portion of the U.S. dollar-denominated assets in the Aflac Japan segment into yen, which could have a material adverse effect on the Company's business, results of operations or financial condition. The Company’s floating rate investments typically bear interest based on the London Interbank Offered Rate (LIBOR). Regulatory and industry initiatives to eliminate LIBOR as an interest rate benchmark may create uncertainty in the valuation of LIBOR-based loans, as well as for other LIBOR-based derivatives and assets. This may adversely impact both pricing and liquidity in such instruments. The Company is unable to predict with certainty how LIBOR elimination may impact markets, pricing, liquidity and other factors or the Company's activities.
Changes in interest rates impact unrealized gains and losses of fixed income securities in the Company's investment portfolio; however, they do not have a direct impact on the related valuation of the corresponding liabilities. Prolonged periods of low interest rates, as have been experienced in recent years, heighten the risk associated with future increases in interest rates because an increasing proportion of the Company's investment portfolio includes investments that bear lower rates of return than the embedded book yield of the investment portfolio. A rise in interest rates could decrease the fair value of the Company's debt securities. Some of the insurance products that Aflac sells in the U.S. and Japan provide cash surrender values. A rise in interest rates could trigger significant policy surrenders, which might require the Company to sell investment assets and recognize unrealized losses. This situation is commonly referred to as disintermediation risk. The Company generally invests its assets to match the duration and cash flow characteristics of its policy liabilities, and therefore would not expect to realize most of these gains or losses, however, the Company's risk is that unforeseen events or economic conditions, such as changes in interest rates resulting from governmental monetary policies, domestic and international economic and political conditions, and other factors beyond the Company's control will reduce the effectiveness of this strategy. These events or economic conditions could either cause the Company to dispose of some or all of these investments prior to their maturity, or increase the risk that the issuers of these securities may default or may require impairment, which could result in the Company having to recognize such gains or losses.

14



Rising interest rates also negatively impact the SMR since unrealized losses on the available-for-sale investment portfolio factor into the ratio. For regulatory accounting purposes for Aflac Japan, there are certain requirements for realizing impairments that could be triggered by rising interest rates, negatively impacting Aflac Japan's earnings and corresponding dividends and capital deployment.
Further, interest rate risk is still an inherent portfolio, business and capital risk for the Company, and significant changes in interest rates could have a material adverse effect on the Company's consolidated results of operations, financial condition or cash flows through realized losses, impairments, changes in unrealized positions, and liquidity.

For more information regarding interest rate risk, see the Interest Rate Risk subsection within the Market Risks of Financial Instruments section of MD&A in this report.

The Company's concentration of business in Japan poses risks to its operations.
The Company's operations in Japan, including realized gains and losses on Aflac Japan's investment portfolio, accounted for 69% of the Company's total revenues in 2019, and 70% in both 2018 and 2017. The Japanese operations accounted for 83% of the Company's total assets at December 31, 2019, compared with 84% at December 31, 2018.

Further, because of the concentration of the Company's business in Japan and its need for long-dated yen-denominated assets, the Company has a substantial concentration of Japan Government Bond (JGBs) in its investment portfolio. As such the Company has material exposure to the Japanese economy, geo-political climate, political regime, and other factors that generally determine a country's creditworthiness. Specifically, the NRSROs, credit rating agencies registered with the SEC, have placed increased scrutiny on JGBs, which are a significant component of the Company’s overall investment portfolio, resulting in downgrades as discussed later in this Risk Factors section. 

The Company seeks to match investment currency and interest rate risk to its yen liabilities. The low level of interest rates available on yen-denominated securities has a negative effect on overall net investment income. A large portion of the cash available for reinvestment each year is deployed in yen-denominated instruments and subject to the low level of yen interest rates.

Any potential deterioration in Japan's credit quality, market access, the overall economy of Japan, or Japanese market volatility could adversely impact the business of Aflac in general and specifically Aflac Japan and its related results of operations and financial condition.

Lack of availability of acceptable yen-denominated investments could adversely affect the Company's results of operations, financial position or liquidity.
The Company attempts to match both the duration and currency of its assets with its liabilities. This is very difficult for Aflac Japan due to the lack of available long-dated yen-denominated fixed income instruments beyond JGBs.

Prior to the onset of the financial crisis of 2008, the Company was focused on investing cash flows in JGBs, which had relatively low yields, and utilizing private placement and perpetual securities to gain additional yield, extend the duration of the investment portfolio, and maintain yen exposure. Given call activity with respect to certain of the Company's legacy private placement investments, the Company has added a modest amount of yen-denominated private placements to its investment portfolio in recent periods. The investment in private placements carries risk associated with illiquidity, which is managed and monitored by the Company.

Starting in 2012, Aflac Japan augmented its investment strategy to include U.S. dollar-denominated investments, some of which could then be hedged back to yen. Initially this program focused on public investment-grade bonds but has evolved over time to include U.S. dollar-denominated investment-grade commercial mortgage loans, middle market loans, infrastructure debt, as well as other loan types, high yield bond and public and private equities. The Company plans to continue adding other instruments denominated in U.S. dollars, including floating rate investments, to improve the portfolio diversification and/or return profile. Some of the U.S. dollar-denominated asset classes that the Company has added, and anticipates continuing to add, have less liquidity than investment-grade corporate bonds. These strategies will continue to increase the Company's exposure to U.S. interest rates, credit spreads and other risks. The Company has increased foreign exchange risk exposure as the comprehensive hedging program may not always correlate to the underlying U.S. dollar-denominated assets, thereby increasing earnings volatility. These risks can significantly impact the Company's consolidated results of operations, financial position or liquidity.


15



Investing in U.S. dollar-denominated investments in Aflac Japan also creates an unmatched foreign currency exposure and related SMR volatility, as Aflac Japan’s insurance liabilities are yen-denominated. Although the Company engages in certain foreign exchange hedging activities to partially mitigate this risk, and such hedged assets may be used to satisfy yen-denominated insurance liabilities and other business obligations, important risks remain.

Foreign exchange derivatives used for hedging are periodically settled, which results in cash receipt or payment at maturity or early termination. Cumulative net cash settlements on derivatives hedging currency exposure of Aflac Japan's U.S. dollar-denominated investments are associated with existing U.S. dollar-denominated investments that continue to be hedged, previously hedged investments that continue to be held but are no longer hedged, as well as, investments previously hedged that have since been sold, matured or redeemed and may or may not have not been converted to yen. The Company’s foreign exchange derivatives are typically shorter-dated than the underlying U.S. dollar-denominated investments being hedged, which creates roll-over risks within the hedging program that could increase the cost of such derivatives. If the Company reduces the notional amount of foreign exchange derivatives prior to the maturity of the hedged U.S. dollar-denominated investments, the foreign exchange gains or losses on the U.S. dollar-denominated investments remain economically unrealized. These foreign currency gains or losses on the investments are only economically realized, or monetized, through sale, maturity or redemption of the investments and concurrent conversion to yen. However, the Company may not realize the benefit of offsetting adverse cash settlements on hedging derivatives with cash receipts on the U.S. dollar-denominated investments if the currency exchange rates move in an adverse direction before the investments are converted to yen, or if the investments are never converted to yen. As an example of the latter, if the Company’s actual insurance risk experience in Japan is as expected or more favorable than expected, the need for yen to pay expenses and claims would correspondingly remain at or below expected levels, thereby diminishing operational requirements to convert U.S. dollar-denominated investments to yen. The settlement of the foreign exchange derivatives is reported in the investing activities section of the Company’s consolidated statements of cash flows in the line item “Settlement of derivatives, net.”

For more information regarding unhedged U.S. dollar-denominated securities, see the risk factor entitled, “The Company is exposed to foreign currency fluctuations in the yen/dollar exchange rate.” For more information regarding Aflac Japan's U.S. dollar-denominated investments and hedging activities, see the "Hedging Activities"subsection within the MD&A of this report, and for more information regarding foreign currency risk, see the "Currency Risk" subsection within the Item 7A. Quantitative and Qualitative Disclosures about Market Risk section in this report.

If the Company fails to comply with restrictions on customer privacy and information security, including taking steps to ensure that its third-party service providers and business associates who access, store, process or transmit sensitive customer information maintain its security, integrity, confidentiality and availability, the Company's reputation and business operations could be materially adversely affected.

The collection, maintenance, use, protection, disclosure and disposal of individually identifiable data by the Company's businesses are regulated at the international, federal and state levels. These laws and rules are subject to change by legislation or administrative or judicial interpretation. Various state laws address the unauthorized access and acquisition of personal information and the use and disclosure of individually identifiable health data to the extent they are more restrictive than those contained in the privacy and security provisions in the federal GLBA and in the HIPAA. HIPAA also requires that the Company imposes privacy and security requirements on its business associates (as such term is defined in the HIPAA regulations). With regard to personal information obtained from policyholders, the insured, or others, Aflac Japan is regulated in Japan by the APPI and guidelines issued by FSA and other governmental authorities.

The Company relies on third parties, and in some cases subcontractors, to provide information technology and data services. It also relies on various parties in its distribution channels including agencies, banks and Japan Post in Japan, as well as sales associates and brokers in the U.S., to provide services to prospective and existing customers. Although the Company provides for appropriate protections through its contracts and performs information security risk assessments of its third-party service providers and business associates, the Company still has limited control over their actions and practices. In addition, despite the security measures the Company has in place to ensure compliance with applicable laws and rules, the Company's facilities and systems, and those of the Company's third-party providers and participants in its distribution channels may be vulnerable to security breaches, acts of vandalism or theft, computer viruses, misplaced or lost data, programming and/or human errors or other similar events. From time to time, the Company, its third party providers and participants in the Company’s distribution channels have experienced and will likely continue to experience such events. In such cases, notification to affected individuals, state and federal regulators, state attorneys general and media may be required, depending upon the number of affected individuals and whether personal information including health or financial data was subject to unauthorized access.

The U.S. Congress and many states are considering new privacy and security requirements that would apply to the Company's business. Compliance with new privacy and security laws, requirements, and new regulations may result in cost

16



increases due to necessary systems changes, new limitations or constraints on the Company's business models, the development of new administrative processes, and the effects of potential noncompliance by the Company's business associates. They also may impose further restrictions on the Company's collection, disclosure and use of customer identifiable data that are housed in one or more of the Company's administrative databases. Noncompliance with any privacy laws or any security breach involving the misappropriation, loss, theft or other unauthorized disclosure of sensitive or confidential customer information, whether by the Company or by one of its third parties, could have a material adverse effect on the Company's business, reputation, brand and results of operations, including: material fines and penalties; compensatory, special, punitive and statutory damages; consent orders regarding the Company's privacy and security practices; adverse actions against the Company's licenses to do business; and injunctive relief.

In addition, under Japanese laws and regulations, including the APPI, if a leak or loss of personal information by Aflac Japan or its business associates should occur, depending on factors such as the volume of personal data involved and the likelihood of other secondary damage, Aflac Japan may be required to file reports to the FSA; issue public releases explaining such incident to the public; or become subject to an FSA business improvement order, which could pose a risk to the Company's reputation.

Interruption in telecommunication, information technology and other operational systems, or a failure to maintain the security, confidentiality, integrity or privacy of sensitive data residing on such systems, could harm the Company's business.

The Company stores confidential policyholder, employee, agent, and other proprietary information on its information technology systems. In addition, the Company depends heavily on its telecommunication, information technology and other operational systems and on the integrity and timeliness of data it uses to run its businesses and service its customers. These systems may fail to operate properly or become disabled as a result of events or circumstances wholly or partly beyond the Company's control. Additionally, design flaws may exist in certain systems, processes, software, or configurations that in turn may result in system failure, data corruption, or compromise. Despite the Company's implementation of a variety of security measures to defend against threats incurred on a daily basis, its information technology and other systems, as well as those of third party providers and participants in the Company’s distribution channels, have been and will likely continue to be subject to physical or electronic break-ins, unauthorized tampering, security breaches or other cyber-attacks, that may result in the failure to adequately maintain the security, confidentiality, integrity, or privacy of sensitive data, including personal information relating to customers and prospective customers, or in the misappropriation of the Company's intellectual property or proprietary information.

From time to time, the Company, its third party providers and participants in the Company’s distribution channels have experienced and will likely continue to experience such events. Although the minor data leakage issues the Company has experienced to date have not had a material effect on its business, there is no assurance that the Company's security systems or processes will prevent or mitigate future break-ins, tampering, security breaches or other cyber-attacks. Interruption in telecommunication, information technology and other operational systems, or a failure to maintain the security, confidentiality or privacy of sensitive data residing on such systems, whether due to actions by the Company or others, including third party providers and participants in the company’s distribution channels, could delay or disrupt the Company's ability to do business and service its customers, seriously harm the Company's brand and reputation as well as the Company's ability to compete effectively, subject it to regulatory sanctions and other claims, lead to a loss of customers and revenues and otherwise adversely affect the Company's business. In addition, the costs to address or remediate system interruptions or security threats and vulnerabilities, whether before or after an incident, could be significant.

While the Company continues to invest in the infrastructure of its data security programs, the Company, as well as its third party providers and participants in the Company’s distribution channels, have been, and will likely continue to be, the target of unauthorized access, social engineering, phishing, cyber-attacks, web application attacks, computer viruses or other malicious codes, or other computer-related penetrations. Although the Company attempts to manage its exposure to such events through the purchase of cyber liability insurance, such events are inherently unpredictable and insurance may not be sufficient to protect the Company against all losses. As a result, events such as these could adversely affect the Company's financial condition or results of operation.


17



Catastrophic events could adversely affect the Company's financial condition and results of operations as well as the availability of the Company’s infrastructure and systems.

The Company's insurance operations are exposed to the risk of catastrophic events including, but not necessarily limited to, epidemics, pandemics, tornadoes, hurricanes, earthquakes, tsunamis, war or other military action, and terrorism or other acts of violence. The extent of losses from a catastrophe is a function of both the total amount of insured exposure in the area affected by the event and the severity of the event. Certain events such as earthquakes, tsunamis, hurricanes and man-made catastrophes could cause substantial damage or loss of life in larger areas, especially those that are heavily populated. Claims resulting from natural or man−made catastrophic events could cause substantial volatility in the Company's financial results for any fiscal quarter or year and could materially reduce its profitability or harm the Company's financial condition, as well as affect its ability to write new business.

Additionally, the Company's business operations may be adversely affected by such catastrophic events to the extent they disrupt the Company's physical infrastructure, human resources or systems that support its businesses and customers. Although the Company has a global crisis management framework to minimize the business disruption from a catastrophic event, such framework may not be effective to avoid an adverse impact to the Company from such an event.

Difficult conditions in global capital markets and the economy could have a material adverse effect on the Company's investments, capital position, revenue, profitability, and liquidity and harm the Company's business.
The Company's results of operations are materially affected by conditions in the global capital markets and the global economy generally, including in its two primary operating markets of the U.S. and Japan. Weak global financial markets impact the value of the Company's existing investment portfolio, influence opportunities for new investments, and may contribute to generally weak economic fundamentals, which can have a negative impact on its operating activities.

In recent years, global capital markets have been severely impacted by several major events. The financial crisis that began in the latter part of 2008 saw dramatic declines in investment values and weak economic conditions as the global financial system came under extreme pressure. Although U.S. markets began recovering in late 2009 and 2010, Europe continued to struggle under a severely weakened banking system and investor concerns with sovereign debt levels. Following a period of unprecedented intervention by governments and central banks, including the U.S. Federal Reserve and European Central Bank (ECB), financial conditions improved from the dire conditions of the global financial crisis, global recession, and European debt crisis. More recently, global markets have experienced bouts of volatility due to uncertainty surrounding a British exit from the European Union, Japan’s continued recovery amidst assorted policy changes, volatility in global commodity prices including oil, divergent monetary policies in the U.S. versus many other developed economies, heightened concerns surrounding the Chinese economy and increasing protectionism in U.S. foreign trade policy. While capital and market conditions have been generally favorable in the last year, the prospect for increased volatility remains.

A shift in the global trading policies by the U.S. and subsequent trade conflict with China has raised concerns about a slowdown of the Chinese economy and the recent trade agreement between the U.S. and China left tariffs in place and many trade issues unresolved. In addition, the recent trade agreement between the U.S. and Japan resulted in tariff reductions on some products but left tariffs on other products in place. While it is not expected that the Company's products would be directly impacted by tariffs, any resulting economic downturn could adversely affect the Company.

Activity by the government of North Korea in 2018 was the subject of increasing focus for a number of other governments, including those of the U.S. and Japan. Although hostile rhetoric decreased in 2019, there is a possibility of renewed hostility between their governments. In addition, in January 2020, hostility between the government of the U.S. and the government of Iran increased, ultimately culminating in a number of missile strikes. Such activity and related geopolitical risk could have a significant impact on financial market conditions across the world. Under certain circumstances, government actions taken in response to these or similar situations could have a material impact on the Company's operations and financial performance, including the indirect impact of potentially severe and prolonged capital market volatility and disruption.

As the Company holds a significant amount of fixed maturity securities issued by borrowers located in many different parts of the world, including a large portion issued by banks and financial institutions, sovereigns, and other corporate borrowers in the U.S. and Europe, its financial results are directly influenced by global financial markets. A retrenchment of the recent strength of the capital markets could adversely affect the Company's financial condition, including its capital position and overall profitability. Market volatility and recessionary pressures could result in significant realized or unrealized losses due to severe price declines driven by increases in interest rates or credit spreads, defaults in payment of principal or interest, or credit rating downgrades.

Following the election of Shinzo Abe as Prime Minister of Japan in December 2012, the new administration adopted a new set of financial measures to stimulate the Japanese economy, including imposing negative interest rates on excess bank reserves. In December 2014 and October 2017 snap-elections, the ruling Liberal Democratic Party (LDP) won decisive victories further strengthening Mr. Abe's ability to continue with economic reforms and address key policy challenges. In September 2018, Mr. Abe won reelection to another three-year term as president of the LDP. Most recently, the BoJ signaled to hold its policy rate at zero and to continue yield curve control to maintain a targeted yield on the 10-year JGB. Prime Minister Abe’s election victories may result in the continuation of current monetary policy, but there can be no guarantee that this is the case.

Japan is the largest market for the Company's products, and the Company owns substantial holdings in JGBs. Government actions to stimulate the economy affect the value of the Company's existing holdings, its reinvestment rate on new investments in JGBs or other yen-denominated assets, and consumer behavior relative to the Company's suite of products. The additional government debt from fiscal stimulus actions could adversely impact the Japan sovereign credit profile, which could in turn lead to volatility in Japanese capital and currency markets.

The Company's investment portfolio has sizeable credit positions in many other geographic areas of the world including the Middle East, Latin America, Asia, and other emerging markets. Deterioration in their underlying economies, sovereign credit worthiness, or financial market conditions could negatively impact the Company's financial position.

While the Company has continued to add floating rate investments to its investment portfolio, most of its investment portfolio holdings are income-producing bonds that provide a fixed level of income. Many of the Company's investments were made at the relatively low level of interest rates prevailing over the last decade. Any increase in the market yields of the Company's holdings due to an increase in interest rates could create substantial unrealized losses in the Company's portfolio, as discussed further in a separate risk factor in this section of the Form 10-K.

The Company needs liquidity to pay its operating expenses, dividends on its common stock, interest on its debt, and liabilities. For a further description of the Company's liquidity needs, including maturing indebtedness, see the Liquidity and Capital Resources section of MD&A in this report. In the event the Company's current resources do not meet its needs, the Company may need to seek additional financing. The Company's access to additional funding will depend on a variety of factors such as market conditions, the general availability of credit to the financial services industry and its credit rating.

Should investors become concerned with any of the Company's investment holdings, including the concentration in JGBs, its access to market sources of funding could be negatively impacted. There is a possibility that lenders or debt investors may also become concerned if the Company incurs large investment losses or if the level of the Company's business activity decreases due to a market downturn or there are further adverse economic trends in the U.S. or Japan, specifically, or generally in developed markets. Similarly, the Company's access to funds may be impaired if regulatory authorities or rating agencies take negative actions. See more information on recent rating actions later in this Risk Factors section.

Broad economic factors such as consumer spending, business investment, government spending, the volatility and strength of the capital markets, and inflation all affect the business and economic environment and, indirectly, the amount and profitability of the Company's business. In an economic downturn characterized by higher unemployment, lower family income, lower corporate earnings, lower business investment and lower consumer spending, the demand for financial and insurance products could be adversely affected. This adverse effect could be particularly significant for companies such as Aflac that distribute supplemental, discretionary insurance products primarily through the worksite in the event that economic conditions result in a decrease in the number of new hires and total employees. Adverse changes in the economy could potentially lead the Company's customers to be less inclined to purchase supplemental insurance coverage or to decide to cancel or modify existing insurance coverage, which could adversely affect the Company's premium revenue, results of operations and financial condition. The Company is unable to predict the course of the global financial markets or the recurrence, duration or severity of disruptions in such markets.

Events, including those external to the Company's operations, could damage the Company's reputation.

The Company has made significant investments in the Aflac brand over a long period of time. Because insurance products are intangible, the Company's ability to compete for and maintain policyholders relies to a large extent on consumer trust in the Company's business, including its alliance partners, sales associates and other distribution partners. The perception of unfavorable business practices or financial weakness with respect to the Company, its alliance partners, sales associates or other distribution partners could create doubt regarding the Company's ability to honor the commitments it has made to its policyholders. Such a perception could also negatively impact the Company’s ability to attract and retain qualified sales associates, brokers and other distribution partners, including its alliance partners in Japan, and could have a material adverse effect on the Company's sales, results of operations and financial condition. Maintaining the Company's stature as a trustworthy

19



insurer and responsible corporate citizen, which helps support the strength of the Company's brand, is critical to the Company's reputation and the failure or perceived failure to do so could adversely affect the Company's brand value, financial condition and results of operations. For example, negative publicity or allegations of unfavorable business practices or poor governance can be rapidly and widely shared over social or traditional media or other means, and could reduce demand for the Company's insurance products, reduce the Company's ability to recruit and retain employees, or lead to greater regulatory scrutiny of the Company's operations.

Extensive regulation and changes in legislation can impact profitability and growth.

Aflac's insurance subsidiaries are subject to complex laws and regulations that are administered and enforced by a number of governmental authorities, including the FSA and Ministry of Finance (MOF) in Japan, and state insurance regulators, the SEC, the NAIC, the FIO, the U.S. Department of Justice, state attorneys general, the U.S. Commodity Futures Trading Commission, and the U.S. Treasury, including the Internal Revenue Service (IRS), in the U.S., each of which exercises a degree of interpretive latitude. In addition, proposals regarding the global regulation of insurance are under discussion, and changes to corporate form that attend the conversion of Aflac Japan to a subsidiary may introduce new forms of regulation compared to those with which the Company has historically been subject. For example, AAMJ is licensed as a discretionary asset manager under the Japan Financial Instruments and Exchange Act and is subject to rules of the Japan Investment Advisors Association, a self-regulatory organization with mandatory membership for Japan investment managers. Consequently, the Company is subject to the risk that compliance with any particular regulator's or enforcement authority's interpretation of a legal or regulatory issue may not result in compliance with another regulator's or enforcement authority's interpretation of the same issue, particularly when compliance is judged in hindsight. There is also a risk that any particular regulator's or enforcement authority's interpretation of a legal or regulatory issue may change over time to the Company's detriment. In addition, changes in the overall legal or regulatory environment may, even absent any particular regulator's or enforcement authority's interpretation of an issue changing, cause us to change the Company's views regarding the actions the Company needs to take from a legal or regulatory risk management perspective, thus necessitating changes to the Company's practices that may, in some cases, limit its ability to grow or otherwise negatively impact the profitability of the Company's business.

The primary purpose of insurance company regulatory supervision is the protection of insurance policyholders, rather than investors. The extent of regulation varies, but generally is governed by state statutes in the U.S. and by the FSA and the MOF in Japan. These systems of supervision and regulation cover, among other things:

standards of establishing and setting premium rates and the approval thereof
standards of minimum capital and reserve requirements and solvency margins, including RBC measures
restrictions on, limitations on and required approval of certain transactions between the Company's insurance subsidiaries and their affiliates, including management fee arrangements
restrictions on the nature, quality and concentration of investments
restrictions on the types of terms and conditions that the Company can include in the insurance policies offered by its primary insurance operations
limitations on the amount of dividends that insurance subsidiaries can pay
the existence and licensing status of a company under circumstances where it is not writing new or renewal business
certain required methods of accounting
reserves for unearned premiums, losses and other purposes
assignment of residual market business and potential assessments for the provision of funds necessary for the settlement of covered claims under certain policies provided by impaired, insolvent or failed insurance companies
administrative practices requirements
imposition of fines and other sanctions
Regulatory authorities periodically re-examine existing laws and regulations applicable to insurance companies and their products. Changes in these laws and regulations, or in interpretations thereof, could have a material adverse effect on the Company's financial condition and results of operations. If the Company's subsidiaries fail to meet the minimum capital or operational requirements established by its respective regulators, they could be subject to examination or corrective action, or the Company's financial strength ratings could be downgraded, or both.

Compliance with applicable laws and regulations is time consuming and personnel-intensive, and changes in these laws and regulations may materially increase the Company's direct and indirect compliance and other expenses of doing business, thus having a material adverse effect on the Company's financial condition and results of operations.


20



The Companyis exposed to foreign currency fluctuations in the yen/dollar exchange rate.

Due to the size of Aflac Japan, where functional currency is the Japanese yen, fluctuations in the rate of exchange between the yen and the U.S. dollar can have a significant effect on the Company's reported financial position and results of operations. Aflac Japan's premiums and approximately half of its investment income are received in yen, and its claims and most expenses are paid in yen. Aflac Japan purchases yen-denominated assets and U.S. dollar-denominated assets, which may be hedged to yen, to support yen-denominated policy liabilities. These and other yen-denominated financial statement items are, however, translated into U.S. dollars for financial reporting purposes. Accordingly, fluctuations in the yen/dollar exchange rate can have a significant effect on the Company's reported financial position and results of operations. In periods when yen weakens, translating yen into U.S. dollars causes fewer U.S. dollars to be reported. When yen strengthens, translating yen into U.S. dollars causes more U.S. dollars to be reported. Any unrealized foreign currency translation adjustments are reported in accumulated other comprehensive income. As a result, yen weakening has the effect of suppressing current year results in relation to the prior year, while yen strengthening has the effect of magnifying current year results in relation to the prior year. In addition, the weakening of the yen relative to the U.S. dollar will generally adversely affect the value of the Company's yen-denominated investments in U.S. dollar terms.

The Company engages in certain foreign currency hedging activities for the purpose of hedging the yen exposure to its net investment in operations in Japan. These hedging activities are limited in scope, and the Company cannot provide assurance that these activities will be effective.

Unhedged U.S. dollar-denominated securities held by Aflac Japan are exposed to foreign exchange fluctuations, which impact SMR. In periods of yen strengthening, the unhedged U.S. dollar-denominated investments will experience unrealized foreign exchange losses, negatively impacting SMR. This impact increases when the size of the unhedged U.S. dollar-denominated portfolio increases, which can occur due to the purchase of additional unhedged U.S. dollar-denominated investments, or through termination or expiration of existing hedges. Unrealized currency gains and losses on unhedged U.S. dollar-denominated securities are monetized (or, in other words, are economically realized) only upon converting the proceeds from the sale, maturity or redemption of these securities to yen, which primarily occurs when yen are needed to satisfy policyholder obligations or other business expenses of Aflac Japan. To mitigate exposure to the foreign exchange risk from U.S. dollar-denominated investments and to reduce SMR volatility, the Company engages in certain currency hedging activities. However, these hedging activities are limited in scope and the Company cannot provide assurance that its hedging strategies will be effective. As a result, periods of unusually volatile currency exchange rates could result in limitations on dividends available to the Parent Company.

As indicated in the MD&A, the Company has determined that the unhedged U.S. dollar-denominated investment portfolio acts as a natural economic currency hedge of a portion of the Company’s investment in Aflac Japan against erosion of economic value. However, the unhedged U.S. dollar-denominated investment portfolio at the same time creates an unmatched foreign currency exposure and subjects Aflac Japan to volatility in regulatory capital and earnings, which may adversely impact Aflac Japan’s ability to pay dividends to the Parent Company. The overall investment strategy in Aflac Japan is guided primarily by the objective of securing the long-term financial strength of Aflac Japan and funding of yen liabilities. As a result, the Company has historically maintained and currently maintains the size of the unhedged portfolio at levels below the economic equity surplus in Aflac Japan. However, there can be no assurance that this strategy will be successful.

Furthermore, for regulatory accounting purposes, there are certain requirements for realizing impairments that could be triggered by changes in the rate of exchange between the yen and U.S. dollar and could negatively impact Aflac Japan's earnings and the corresponding dividends and capital deployment.

Additionally, the Company is exposed to currency risk when yen cash flows are converted into U.S. dollars, resulting in an increase or decrease in the Company's U.S. dollar-denominated cash flows and earnings when exchange gains or losses, respectively, are realized. This primarily occurs when the Company dividends funds from Aflac Japan to the Parent Company, but it also has an impact when cash in the form of yen is converted to U.S. dollars for investment into U.S. dollar-denominated assets. The exchange rates prevailing at the time of dividend payment may differ from the exchange rates prevailing at the time the yen profits were earned. In 2018, the Parent Company began entering into forward contracts to accomplish a dual objective of hedging foreign currency exchange rate risk related to dividend payments by Aflac Japan, and reducing enterprise-wide hedge costs. If the markets experience a significant strengthening of yen, this could cause cash strain at the Parent Company as a result of cash collateral and potentially cash settlement requirements. Based on the timing and severity of exchange rate fluctuations combined with the level of outstanding activity in this program, the cash strain at the Parent Company could be significant. 

For more information regarding unhedged U.S. dollar-denominated securities, see the risk factor below entitled, “Lack of availability of acceptable yen-denominated investments could adversely affect the Company’s results of operations, financial

21



position or liquidity”. For more information regarding foreign currency risk, see the Currency Risk subsection within the Market Risks of Financial Instruments section of MD&A.

Tax rates applicable to the Company may change.

The Company is subject to taxation in Japan, and in the U.S. under federal and numerous state and local tax jurisdictions. In preparing the Company's financial statements, the Company estimates the amount of tax that will become payable, but the Company's effective tax rate may be different than estimates due to numerous factors including accounting for income taxes, the mix of earnings from Japan and the U.S., the results of tax audits, adjustments to the value of uncertain tax positions, changes to estimates and other factors. Further, changes in U.S. or Japan tax laws or interpretations of such laws could increase the Company's corporate taxes and reduce earnings.

In addition, it remains difficult to predict the timing and effect that future tax law changes could have on the Company's earnings both in the U.S. and in foreign jurisdictions. Any of these factors could cause the Company to experience an effective tax rate significantly different from previous periods or the Company's current estimates. If the Company's effective tax rate were to increase, the Company's financial condition and results of operations could be adversely affected.

A decline in the creditworthiness of other financial institutions could adversely affect the Company.

The Company has exposure to and routinely executes transactions with counterparties in the financial services industry, including broker dealers, derivative counterparties, commercial banks and other institutions.

The Company uses derivative instruments to mitigate various risks associated with its investment portfolio, notes payable, and subsidiary dividends. The Company enters into a variety of agreements involving assorted instruments including foreign currency forward contracts; foreign currency options; foreign currency swaps; and interest rate swaps and swaptions. The Company's use of derivatives results in financial exposure to derivative counterparties. If the Company's counterparties fail or refuse to honor their obligations under derivative instruments, the Company's hedges of the risks will be ineffective, and the Company's financial condition and results of operations could be adversely affected.

The Company engages in derivative transactions directly with unaffiliated third parties under International Swaps and Derivatives Association, Inc. (ISDA) agreements and other documentation. Most of the ISDA agreements also include Credit Support Annexes (CSAs) provisions, which generally provide for two-way collateral postings at the first dollar of exposure. The Company mitigates the risk that counterparties to transactions might be unable to fulfill their contractual obligations by monitoring counterparty credit exposure and collateral value while generally requiring that collateral be posted at the outset of the transaction. In addition, a significant portion of the derivative transactions have provisions that give the counterparty the right to terminate the transaction upon a downgrade of Aflac’s financial strength rating. The actual amount of payments that the Company could be required to make, depends on market conditions, the fair value of outstanding affected transactions, and other factors prevailing at and after the time of the downgrade. If the Company is required to post collateral to support derivative contracts and/or pay cash to settle the contracts at maturity, the Company's liquidity could be strained. In addition, the Company's cleared swaps result in counterparty exposure to clearing brokers and central clearinghouses; while this exposure is mitigated in part by clearinghouse and clearing broker capital and regulation, no assurance can be provided that these counterparties will fulfill their obligations. The Company also has exposure to counterparties to securities lending transactions in the event they fail to return loaned securities. The Company is also exposed to the risk that there may be a decline in value of securities posted as collateral for securities lending programs or a decline in value of investments made with cash posted as collateral for such programs.

Further, the Company has agreements with various financial institutions for the distribution of its insurance products. For example, at December 31, 2019, the Company had agreements with 367 banks to market Aflac's products in Japan. Sales through these banks represented 4.3% of Aflac Japan's new annualized premium sales in 2019. Any material adverse effect on these or other financial institutions could also have an adverse effect on the Company's sales.
The Company has entered into significant reinsurance transactions with large, highly rated counterparties. Negative events or developments affecting any one of these counterparties could have an adverse effect on the Company's financial position or results of operations.
All of these risks related to exposure to other financial institutions could adversely impact the Company's consolidated results of operations and financial condition.


22



The determination of the amount of impairments taken on the Company's investments is based on significant valuation judgments and could materially impact its results of operations or financial position.
An investment in a fixed maturity security is impaired if the fair value falls below book value. The Company regularly reviews its entire investment portfolio for declines in value. The majority of the Company's investments are evaluated for other-than-temporary impairment using the Company's debt impairment model.
The Company's debt impairment model includes emphasis on the ultimate collection of the cash flows from its investments. The determination of the amount of impairments under this model is based upon the Company's periodic evaluation and assessment of known and inherent risks associated with the respective securities. Such evaluations and assessments are revised as conditions change and new information becomes available.
For the Company's fixed maturity securities reported in the available-for-sale portfolio, the Company reports the investments at fair value in the statement of financial condition and records any unrealized gain or loss in the value of the asset in accumulated other comprehensive income. For the Company's held-to-maturity securities portfolio, the Company reports the investments at amortized cost. Under the debt impairment model, the determination of whether an impairment in value is other than temporary is based largely on the Company's evaluation of the issuer's creditworthiness. The Company must apply considerable judgment in determining the likelihood of the security recovering in value while the Company owns it. Factors that may influence this include the Company's assessment of the issuer’s ability to continue making timely payments of interest and principal, the overall level of interest rates and credit spreads, and other factors. The Company also verifies whether it has the intent to sell or if it is more likely than not the Company would be required to sell the security prior to recovery of its amortized cost. If the Company determines it is unlikely to recover the book value of the instrument prior to disposal of the security, the Company will reduce the carrying value of the security to its fair value and recognize any associated impairment loss in the Company's consolidated statement of earnings or other comprehensive income, depending on the nature of the loss.
For regulatory accounting purposes for Aflac Japan, there are certain requirements for realizing impairments that could be triggered by rising interest rates, credit-related losses, or changes in foreign exchange, negatively impacting Aflac Japan's earnings and corresponding dividend and capital deployment.
The Company's management updates its evaluations regularly as conditions change and as new information becomes available and reflects impairment losses in the Company's income statement when considered necessary. Furthermore, additional impairments may need to be taken in the future. Historical trends may not be indicative of future impairments.

U.S. tax audit risk related to conversion of the Japan branch to a subsidiary could adversely impact the Company's financial position.

The conversion of the Japan branch to a legal subsidiary, which the Company executed in the second quarter of 2018, was a complex, tax-free transaction that is conditioned on the continued validity of a private letter ruling the Company received from the IRS. Notwithstanding the receipt of the private letter ruling, the IRS could determine that the Japan branch conversion should be treated as a taxable transaction. For example, the IRS could conclude that the representations, assumptions and covenants on which the private letter ruling is based are untrue, not accurate, or have not been fulfilled. If the IRS made such a conclusion, the Company could incur significant U.S. federal income tax liabilities or litigation costs to defend the tax-free treatment of the transaction outlined by the private letter ruling. Such liabilities or costs could have a material adverse effect on the Company's business, results of operations and financial condition.

As a holding company, the Parent Company depends on the ability of its subsidiaries to transfer funds to it to meet its debt service and other obligations and to pay dividends on its common stock.
The Parent Company is a holding company and has no direct operations, and its most significant assets are the stock of its subsidiaries. Because the Parent Company conducts its operations through its operating subsidiaries, the Parent Company depends on those entities for dividends and other payments to generate the funds necessary to meet its debt service and other obligations, to pay dividends on and conduct repurchases of its common stock, and to make investments into its subsidiaries or external investment opportunities.
Aflac is domiciled in Nebraska and is subject to insurance regulations that impose certain limitations and restrictions on payments of dividends, management fees, loans and advances by Aflac to the Parent Company. The Nebraska insurance statutes require prior approval for dividend distributions that exceed the greater of the net income from operations, which excludes net realized investment gains, for the previous year determined under statutory accounting principles, or 10% of statutory capital and surplus as of the previous year-end. In addition, the Nebraska insurance department must approve

23



service arrangements and other transactions within the affiliated group of companies. After the Japan branch conversion, the Nebraska insurance department and the FSA approved their respective domiciled insurance company service arrangements and transactions. The FSA does not allow dividends or other payments from Aflac Japan unless it meets certain financial criteria as governed by Japanese corporate law. Under these criteria, dividend capacity at the Japan subsidiary will be defined as retained earnings plus other capital reserve less net after-tax net unrealized losses on available-for-sale securities.
The ability of Aflac and Aflac Japan to pay dividends or make other payments to the Parent Company could also be constrained by the Company's dependency on financial strength ratings from independent rating agencies. The Company's ratings from these agencies depend to a large extent on Aflac's capitalization level. Any inability of Aflac to pay dividends or make other payments to the Parent Company could have a material adverse effect on the Company's financial condition and results of operations.
For the foregoing reasons, there is no assurance that the earnings from, or other available assets of, the Parent Company's operating subsidiaries will be sufficient to make distributions to enable the Company to operate.
Any decrease in the Company's financial strength or debt ratings may have an adverse effect on its competitive position and access to liquidity and capital.

Financial strength ratings can play an important role in establishing the competitive position of insurance companies. On an ongoing basis, NRSROs review the financial performance and condition of many insurers, including the Company and its competitors. They may assign multiple ratings including a financial strength rating, reflecting their view of the insurer’s ability to pay claims on a timely basis, and ratings on an insurer’s senior and subordinated debt obligations, indicating their view of an insurer’s ability to make timely payments on their debt obligations.

NRSROs may change their ratings or outlook on an insurer's ratings due to a variety of factors including the NRSRO’s assessment of the insurer’s strength of operations and overall financial condition. Some factors that may influence ratings include competitive position; profitability; cash generation and other sources of liquidity; capital levels; quality of the investment portfolio; and perception of management capabilities. The ratings assigned to the Company by the NRSROs are important factors in the Company's ability to access liquidity and capital from the bank market, debt capital markets or other available sources, such as reinsurance transactions. Downgrades to the Company's credit ratings could give its derivative counterparties the right to require early termination of derivatives transactions or delivery of additional collateral, thereby adversely affecting the Company's liquidity.

In view of the difficulties experienced after the financial crisis by many financial institutions, including those in the insurance industry, the NRSROs have heightened the level of scrutiny that they apply to such institutions. Steps taken by the NRSROs include an increase in the frequency and scope of their reviews, additional information requests from the companies that they rate, including additional information regarding the valuation of investment securities held, and, in certain cases, an increase in the capital and other requirements employed in their models for maintenance of certain rating levels.

On September 16, 2015, S&P downgraded their credit rating of Japan’s sovereign debt. Following this action, they also downgraded several other foreign insurers, including the Company. The Company's significant operations in Japan and corresponding regulation by the Japanese FSA, combined with its significant exposure to JGBs as outlined above, resulted in S&P downgrading the financial strength rating of Aflac's core insurance operations to A+ and the Parent Company's senior debt rating to A-, both with a stable outlook. While S&P made no further downgrades to the Company's ratings between 2016 and 2019, they state that a downgrade of Japan's sovereign rating could lead to a downgrade of the Company's financial strength rating. As a matter of policy, S&P rarely rates insurance companies above the sovereign long-term rating of the country of domicile because during times of stress, the sovereign’s regulatory and supervisory powers may restrict an insurer’s or financial system’s flexibility. Moody’s has also stated that the following factors could lead to a downgrade of the Company’s ratings: a downgrade of the U.S. or Japanese operating entities; or a downgrade of the Government of Japan sovereign debt rating.

In addition to the impact on the Company's access to liquidity, as mentioned above, a downgrade of the Company's ratings could have a material adverse effect on agent recruiting and retention, sales, competitiveness and the marketability of its products which could negatively impact the Company's liquidity, operating results and financial condition. Additionally, sales through the bank channel in Japan could be adversely affected as a result of their reliance and sensitivity to ratings levels.


24



The Company cannot predict what actions rating agencies may take, or what actions the Company may take in response to the actions of rating agencies, which could adversely affect the Company's business. As with other companies in the financial services industry, the Company's ratings could be downgraded at any time and without any notice by any NRSRO.

The Company's risk management policies and procedures may prove to be ineffective and leave the Company exposed to unidentified or unanticipated risk, which could adversely affect the Company's businesses or result in losses.

The Company has developed an enterprise-wide risk management and governance framework to mitigate risk and loss to the Company. The Company maintains policies, procedures and controls intended to identify, measure, monitor, report and analyze the risks to which the Company is exposed.
However, there are inherent limitations to risk management strategies because risk may exist, or emerge in the future, that the Company has not appropriately anticipated or identified. If the Company's risk management framework proves ineffective, the Company may suffer unexpected losses and could be materially adversely affected. As the Company's businesses change and the markets in which it operates evolve, the Company's risk management framework may not evolve at the same pace as those changes. As a result, there is a risk that new products or new business strategies may present risks that are not appropriately identified, monitored or managed. In times of market stress, unanticipated market movements or unanticipated claims experience resulting from greater than expected morbidity, mortality, longevity, or persistency, the effectiveness of the Company's risk management strategies may be limited, resulting in losses to the Company. In addition, under difficult or less liquid market conditions, the Company's risk management strategies may not be effective because other market participants may be using the same or similar strategies to manage risk under the same challenging market conditions. In such circumstances, it may be difficult or more expensive for the Company to mitigate risk due to the activity of such other market participants.
Many of the Company's risk management strategies or techniques are based upon historical customer and market behavior and all such strategies and techniques are based to some degree on management’s subjective judgment. The Company cannot provide assurance that its risk management framework, including the underlying assumptions or strategies, will be accurate and effective.
Management of operational, legal and regulatory risks requires, among other things, policies, procedures and controls to record properly and verify a large number of transactions and events, and these policies, procedures and controls may not be fully effective. Models are utilized by the Company's businesses and corporate areas primarily to project future cash flows associated with pricing products, calculating reserves and valuing assets, as well as in evaluating risk and determining capital requirements, among other uses. These models are utilized under a risk management policy approved by the Company's executive risk management committees, however, the models may not operate properly and rely on assumptions and projections that are inherently uncertain. As the Company's businesses continue to grow and evolve, the number and complexity of models the Company utilizes expands, increasing the Company's exposure to error in the design, implementation or use of models, including the associated input data and assumptions.
Past or future misconduct by the Company's employees or employees of the Company's third parties (suppliers which are cost-based relationships and alliance partners which are revenue-generating relationships) could result in violations of law by the Company, regulatory sanctions and/or serious reputational or financial harm and the precautions the Company takes to prevent and detect this activity may not be effective in all cases. Despite the Company's published Supplier Code of Conduct, due diligence of the Company's alliance partners, and rigorous contracting procedures (including financial, legal, IT security, and risk reviews), there can be no assurance that controls and procedures that the Company employs, which are designed to assess third party viability and prevent the Company from taking excessive or inappropriate risks, will be effective. Additionally, the use of third parties also poses operational risks that could result in financial loss, operational disruption, brand damage, or compliance issues. Inadequate oversight of Aflac’s third party suppliers due to the lack of policies, procedures, training and governance may lead to financial loss or damage to the Aflac brand.
The concentration of the Company's investment portfolios in any particular single-issuer or sector of the economy may have an adverse effect on the Company's financial position or results of operations.
Negative events or developments affecting any particular single issuer, industry, group of related industries, asset class or geographic sector may have an adverse impact on a particular holding or set of holdings, which may increase risk of loss from defaults due to non-payment of interest or principal. The Company seeks to minimize this risk by maintaining an appropriate level of diversification. To the extent the Company has concentrated positions, it could have an adverse effect on the Company's results of operations and financial position. The Company's global investment guidelines establish

25



concentration limits for its investment portfolios.

For details on the concentrations within the Company's investment portfolios, see the Investments section of Item 7, MD&A, and the Credit Risk section of Item 7A, Quantitative and Qualitative Disclosures about Market Risk, of this Form 10-K.

The valuation of the Company's investments and derivatives includes methodologies, estimations and assumptions which are subject to differing interpretations and could result in changes to investment valuations that may adversely affect the Company's results of operations or financial condition.
The Company reports a significant amount of its fixed maturity securities and other financial instruments at fair value. As such, valuations may include inputs and assumptions that are less observable or require greater estimation as well as valuation methods which are more sophisticated, thereby resulting in values which may be greater or less than the value at which the investments may be ultimately sold. Rapidly changing and unprecedented credit and equity market conditions could materially impact the valuation of securities as reported within the Company's consolidated financial statements and the period-to-period changes in value could vary significantly.

Valuations of the Company's derivatives fluctuate with changes in underlying market variables, such as interest rates and foreign currency exchange rates. During periods of market turbulence created by political instability, economic uncertainty, government interventions or other factors, the Company may experience significant changes in the volatility of its derivative valuations. Extreme market conditions can also affect the liquidity of such instruments creating marked differences in transaction levels and counterparty valuations. Depending on the severity and direction of the movements in its derivative valuations, the Company will face increases in the amount of collateral required to be posted with its counterparties. Liquidity stresses to the Company may also occur if the required collateral amounts increase significantly over a very short period of time. Conversely, the Company may be exposed to an increase in counterparty credit risk for short periods of time while calling collateral from its counterparties.

Elimination of LIBOR as an interest rate benchmark may create uncertainty in valuation of loans, derivatives and other assets where valuation and interest rates are based on LIBOR, and may create uncertainty in the pricing of such assets in markets for their sale and disposition.

For further discussion on investment and derivative valuations, see the Critical Accounting Estimates section in Item 7, Management's Discussion and Analysis, and Notes 1, 3, 4, and 5 of the Notes to the Consolidated Financial Statements in this Form 10-K.

The Company depends heavily on key management personnel, and the loss of services of one or more of its key executives could harm the Company's business.

The Company’s success depends to a significant extent upon the efforts and abilities of its key management personnel. The loss of the services of one or more of the Company's senior executives could significantly undermine its management expertise and the Company's business could be adversely affected.

Changes in accounting standards issued by the Financial Accounting Standard Boards (FASB) or other standard-setting bodies may adversely affect the Company's financial statements.
The Company's financial statements are subject to the application of U.S. GAAP, which is periodically revised and/or expanded. Accordingly, from time to time the Company is required to adopt new or revised accounting standards issued by recognized authoritative bodies, including the FASB. The impact of accounting pronouncements that have been issued but not yet implemented and are applicable to the Company is disclosed in Note 1 of the Notes to the Consolidated Financial Statements. The pronouncements expected to have the most significant impact on the Company's financial position or results of operations are outlined below.
In June 2016, the FASB issued Accounting Standard Update (ASU) 2016-13, Financial Instruments - Credit Losses: Measurement of Credit Losses on Financial Instruments. The amendments in this update require a financial asset (or a group of financial assets) measured on an amortized cost basis to be presented net of an allowance for current expected credit losses in order to reflect the amount expected to be collected on the financial asset(s). The Company currently estimates the after-tax net impact from the adoption of ASU 2016-13 at a $56 million decrease to retained earnings, which primarily relates to loans and loan receivables. The amendments are effective for fiscal years beginning after December 15, 2019.

26



Additionally, in August 2018 the FASB issued ASU 2018-12, Financial Services - Insurance, Targeted Improvements to the Accounting for Long-Duration Contracts. The amendments in this update will significantly change how insurers account for long-duration contracts. Among the issues addressed in the amendments is the requirement to review and, if there is a change, update cash flow assumptions for the liability for future policy benefits at least annually, and to update the discount rate assumption quarterly. The Company anticipates that the requirement to review and update assumptions for liability for future policy benefits will have a significant impact on its results of operations, systems, processes, and controls, while the requirement to update the discount rate will have a significant impact on the other comprehensive income component of its equity. The amendments are effective for fiscal years beginning after December 15, 2021. See Critical Accounting Estimates section of Item 7. MD&A in this report.

Changes to accounting standards could have a material adverse effect on the Company's results of operations and financial condition. For information on new accounting pronouncements and the impact, if any, on the Company's financial position or results of operations, see Note 1 of the Notes to the Consolidated Financial Statements in this report.
The Company faces risks related to litigation, regulatory investigations and inquiry and other matters.

The Company is a defendant in various lawsuits considered to be in the normal course of business. The final results of any litigation cannot be predicted with certainty, and plaintiffs may seek very large amounts in class actions or other litigation. Although some of this litigation is pending in states where large punitive damages, bearing little relation to the actual damages sustained by plaintiffs, have been awarded in recent years, the Company believes the outcome of pending litigation will not have a material adverse effect on its financial position, results of operations, or cash flows. However, a substantial legal liability or a significant federal, state or other regulatory action against the Company, as well as regulatory inquiries or investigations, could harm the Company's reputation, result in changes in operations, result in material fines or penalties, result in significant costs due to legal fees, settlements or judgments against the Company, or otherwise have a material adverse effect on the Company's business, financial condition and results of operations. Without limiting the foregoing, the litigation and regulatory matters the Company is, has been, or may become, subject to include matters related to sales agent recruiting, policy sales practices, claim payments and procedures including denial or delay of benefits, material misstatements or omissions in the Company's financial reports or other public statements, and/or corporate governance, corporate culture or business ethics matters. Further, the Company may be subject to claims of or litigation regarding sexual or other forms of misconduct or harassment, or discrimination on the basis of race, color, national origin, religion, gender, or other bases, notwithstanding that the Company's Code of Business Conduct and Ethics prohibits such harassment and discrimination by its employees, the Company has ongoing training programs and provide opportunities to report claims of noncompliant conduct, and it investigates and may take disciplinary action regarding alleged harassment or discrimination. Any violations of or deviation from laws, regulations, internal or external codes or standards of normative behavior, or perceptions of such violations or deviations, by the Company's employees or by independent sales agents could adversely impact the Company's reputation and brand value, financial condition and results of operations.

Allegations or determinations of agent misclassification could adversely affect the Company’s results of operations, financial condition and liquidity.

A majority of the Company's U.S. sales force is, and has historically been, comprised of independent agents. While the Company believes that it has properly classified such agents as independent contractors, the Company may be subject to claims, regulatory action by state or federal departments of labor or tax authorities or litigation asserting that such agents are employees. The laws and regulations governing the classification of workers in the U.S. may be changed or interpreted differently compared to past interpretations, including in states where the Company generates significant sales through independent agents. An allegation or determination that independent agents in the Company’s U.S. sales force have been misclassified as independent contractors could result in changes in the Company’s operations and U.S. business model, result in material fines or penalties, result in significant costs due to legal fees, settlements or judgments against the Company, or otherwise have a material adverse effect on the Company's business, results of operation, financial condition and liquidity.

INDUSTRY TRENDS

The Company is impacted by financial markets, economic conditions, regulatory oversight and a variety of trends that affect the industries where it competes.

Financial and Economic Environment

The Company’s business and results of operations are materially affected by conditions in the global capital markets and the economy generally. Stressed conditions, volatility and disruptions in global capital markets, particular markets, or financial asset classes can have an adverse effect on the Company, in part because the Company has a large investment portfolio and its insurance liabilities and derivatives are sensitive to changing market factors. See Item 1A. Risk Factors for the risk factor entitled, "Difficult conditions in global capital markets and the economy could have a material adverse effect on the Company's investments, capital position, revenue, profitability, and liquidity and harm the Company's business."

Demographics

Japan Business - With Japan’s aging population and the rise in healthcare costs, supplemental health care insurance products remain attractive. However, due to the aging population and decline in birthrate, new opportunities for customer demographics are not as readily available. Japan’s existing customers and potential customers seek products that are easily understood, cost-effective and can be accessed through technology-enabled devices.

(2) See the Results of Operations section of this MD&A for a definition of this non-U.S. GAAP financial measure.

35



U.S. Business - Customer demographics continue to evolve and new opportunities present themselves in different customer segments such as the millennial and multicultural markets. Customer expectations and preferences are changing. Trends indicate existing customers and potential customers seek cost-effective solutions that are easily understood and can be accessed through technology-enabled devices. Additionally, income protection and the health needs of retiring baby boomers are continuing to shape the insurance industry.

Regulatory Environment

See Item 1. Business - Aflac U.S. Regulation and Aflac Japan Regulation for a discussion of regulatory developments that may impact the Company and the associated risks.

Competitive Environment

See Item 1. Business - Aflac U.S. Competition and Aflac Japan Competition for a discussion of the competitive environment and the basis on which the Company competes in each of its segments.

2020 OUTLOOK

The Company’s strategy to drive long-term shareholder value is to pursue growth through product development, distribution expansion and digital advancements to improve the customer experience.

The Company's objectives in 2020 are to maintain strong pre-tax margins in its Aflac Japan and Aflac U.S. segments through disciplined product pricing, stable investment returns and leveraging a period of favorable benefit ratios to invest in its platform for future growth and efficiency. The Company believes that its market-leading position, powerful brand recognition and diverse distribution in Japan and the U.S. will provide support toward these objectives.

The Company believes that its efforts will support its prudent strategies for capital deployment in the form of dividends, share repurchases, and opportunistic investments that enhance the Company’s business with a focus on digital distribution and leveraging the Company’s brand, distribution and scale. The Company has stated that the dividend payout ratio from its Aflac Japan segment is likely to be to 100% of FSA earnings from Aflac Japan and 100% of U.S. statutory earnings from Aflac U.S. In its Aflac U.S. segment, the Company plans to maintain a risk-based capital (RBC) ratio in the 500% range for 2020.

Aflac Japan Segment
In Japan, the Company anticipates that the shift in earned premium from first sector savings products to third sector cancer and medical products and first sector protection products, will continue to result in moderately lower benefit ratios in the Aflac Japan segment. The Company also expects this shift in business mix, plus continued investment in IT and digital advancements, to result in moderately higher expense ratios for Aflac Japan. The Company anticipates the Japan segment will face revenue challenges in 2020 due to the run-off and paid-up status of first sector savings and third sector products. The Company expects a decline in the range of .7% in third sector and first sector protection earned premium for 2020. In addition, net investment income is expected to decline modestly as compared to 2019, due in part to the low interest rate environment in Japan and de-risking of the portfolio, partially offset by lower hedge cost as a result of a reduction in the hedge ratio in the fourth quarter of 2019.

Aflac U.S. Segment
The Company expects the profit margins for the Aflac U.S. segment to remain strong, providing a prudent opportunity to reinvest profits back into the U.S. business. The Company anticipates that in 2020, benefit ratios in the U.S. will remain stable and that expense ratios will continue to be elevated in light of investments into U.S. platforms in both the individual and group channels. The Company expects Aflac U.S. to generate earned premium growth in the range of 1% in 2020. Net investment income is expected to decline modestly, primarily as the result of the Company’s implemented U.S. capital and RBC draw-down plan.

Corporate and Other Segment
The Company expects corporate segment results to benefit from net investment income driven by increased capital and liquidity held at the Parent Company, as well as the increase in size of the Company’s enterprise currency hedging strategy. The anticipated increase in investment income is expected to be partially offset by increased costs associated with continued investment in Aflac Corporate Ventures initiatives.

RESULTS OF OPERATIONS

The Company earns its revenues principally from insurance premiums and investments. The Company’s operating expenses primarily consist of insurance benefits provided and reserves established for anticipated future insurance benefits, general business expenses, commissions and other costs of selling and servicing its products. Profitability for the Company depends principally on its ability to price its insurance products at a level that enables the Company to earn a margin over the costs associated with providing benefits and administering those products. Profitability also depends on, among other items, actuarial and policyholder behavior experience on insurance products, and the Company's ability to attract and retain customer assets, generate and maintain favorable investment results, effectively deploy capital and utilize tax capacity, and manage expenses.

Yen–denominated income statement accounts are translated to U.S. dollars using a weighted average Japanese yen/U.S. dollar foreign exchange rate, except realized gains and losses on security transactions which are translated at the exchange rate on the trade date of each transaction. Yen–denominated balance sheet accounts are translated to U.S. dollars using a spot Japanese yen/U.S. dollar foreign exchange rate.

The following discussion includes references to the Company's performance measures, adjusted earnings, adjusted earnings per diluted share, and amortized hedge costs/income, which are not calculated in accordance with U.S. GAAP (non-U.S. GAAP). These measures exclude items that the Company believes may obscure the underlying fundamentals and trends in the Company's insurance operations because they tend to be driven by general economic conditions and events or related to infrequent activities not directly associated with its insurance operations. The Company's management uses adjusted earnings and adjusted earnings per diluted share to evaluate the financial performance of its insurance operations on a consolidated basis, and the Company believes that a presentation of these measures is vitally important to an understanding of its underlying profitability drivers and trends of its insurance business. The Company believes that amortized hedge costs/income, which are a component of adjusted earnings, measure the periodic currency risk management costs/income related to hedging certain foreign currency exchange risks and are an important component of net investment income.

The Company defines the non-U.S. GAAP financial measures included in this filing as follows:

Adjusted earnings are the profits derived from operations.The most comparable U.S. GAAP measure is net earnings. Adjusted earnings are adjusted revenues less benefits and adjusted expenses. The adjustments to both revenues and expenses account for certain items that cannot be predicted or that are outside management’s control. Adjusted revenues are U.S. GAAP total revenues excluding realized investment gains and losses, except for amortized hedge costs/income related to foreign currency exposure management strategies and net interest cash flows from derivatives associated with certain investment strategies. Adjusted expenses are U.S. GAAP total acquisition and operating expenses including the impact of interest cash flows from derivatives associated with notes payable but excluding any nonrecurring or other items not associated with the normal course of the Company’s insurance operations and that do not reflect the Company's underlying business performance.

Adjusted earnings per share (basic or diluted) are adjusted earnings for the period divided by the weighted average outstanding shares (basic or diluted) for the period presented. The most comparable U.S. GAAP measure is net earnings per share.

Amortized hedge costs/income represent costs/income incurred or recognized in using foreign currency forward
contracts to hedge certain foreign exchange risks in the Company's Japan segment (costs) or in the Corporate and Other segment (income). These amortized hedge costs/income are derived from the difference between the foreign currency spot rate at time of trade inception and the contractual foreign currency forward rate, recognized on a straight line basis over the term of the hedge. There is no comparable U.S. GAAP financial measure for amortized hedge costs/income.

Adjusted earnings and adjusted earnings per diluted share excluding current period foreign currency impact are computed using the average yen/dollar exchange rate for the comparable prior year period, which eliminates fluctuations driven solely by yen-to-dollar currency rate changes.


37



Amounts excluding foreign currency impact on U.S. dollar-denominated investment income were determined using the average dollar/yen exchange rate for the comparable prior year period.

Adjusted book value is the U.S. GAAP book value (representing total shareholders' equity), less AOCI as recorded on the U.S. GAAP balance sheet. The Company considers adjusted book value important as it excludes AOCI, which fluctuates due to market movements that are outside management's control.

Adjusted return on equity (ROE) excluding foreign currency impact is calculated using adjusted earnings excluding the impact of the yen/dollar exchange rate, as reconciled with total U.S. GAAP net earnings, divided by average shareholders’ equity, excluding AOCI. The most comparable U.S. GAAP financial measure is return on average equity as determined using net earnings and average total shareholders’ equity.

The following table is a reconciliation of items impacting adjusted earnings and adjusted earnings per diluted share to the most directly comparable U.S. GAAP measures of net earnings and net earnings per diluted share, respectively, for the years ended December 31.

Reconciling Items

Realized Investment Gains and Losses

The Company's investment strategy is to invest primarily in fixed maturity securities to provide a reliable stream of investment income, which is one of the drivers of the Company’s growth and profitability. This investment strategy incorporates asset-liability matching (ALM) to align the expected cash flows of the portfolio to the needs of the Company's liability structure. The Company does not purchase securities with the intent of generating capital gains or losses. However, investment gains and losses may be realized as a result of changes in the financial markets and the creditworthiness of specific issuers, tax planning strategies, and/or general portfolio management and rebalancing. The realization of investment gains and losses is independent of the underwriting and administration of the Company's insurance products. Realized investment gains and

38



losses include securities transactions, impairments, changes in loan loss reserves, derivative and foreign currency activities and changes in fair value of equity securities.
Securities Transactions, Impairments, and Gains (Losses) on Equity Securities

Securities transactions include gains and losses from sales and redemptions of investments where the amount received is different from the amortized cost of the investment. Impairments include other-than-temporary-impairment losses on investment securities as well as changes in loan loss reserves for loan receivables. Starting in the first quarter of 2018, gains and losses from changes in fair value of equity securities are recorded in earnings.
Certain Derivative and Foreign Currency Gains (Losses)

The Company's derivative activities include foreign currency forwards and options on certain fixed maturity securities; foreign currency forwards and options that economically hedge certain portions of forecasted cash flows denominated in yen and hedge the Company's long-term exposure to a weakening yen; foreign currency swaps associated with certain senior notes and subordinated debentures; foreign currency swaps and credit defaults swaps held in consolidated variable interest entities (VIEs); interest rate swaps used to economically hedge interest rate fluctuations in certain variable-rate investments; and interest rate swaptions to hedge changes in the fair value associated with interest rate changes for certain dollar-denominated available-for-sale securities. Gains and losses are recognized as a result of valuing these derivatives, net of the effects of hedge accounting. The Company also excludes the accounting impacts of remeasurement associated with changes in the yen/dollar exchange rate from adjusted earnings. Amortized hedge costs/ income related to certain foreign currency exposure management strategies (see Amortized Hedge Cost/Income section below), and net interest cash flows from derivatives associated with certain investment strategies and notes payable are reclassified from realized investment gains (losses) and included in adjusted earnings.

Amortized hedge costs/income can fluctuate based upon many factors, including the derivative notional amount, the length of time of the derivative contract, changes in both U.S. and Japan interest rates, and supply and demand for dollar funding. Amortized hedge costs and income have fluctuated in recent periods due to changes in the previously mentioned factors. For additional information regarding foreign currency hedging, refer to Hedging Activities in the Investments section of this MD&A.

For additional information regarding realized investment gains and losses, including details of reported amounts for the periods presented, see Notes 3 and 4 of the Notes to the Consolidated Financial Statements.

Other and Non-recurring Items

The U.S. insurance industry has a policyholder protection system that provides funds for the policyholders of insolvent insurers. The system can result in periodic charges to the Company as a result of insolvencies/bankruptcies that occur with other companies in the life insurance industry. Some states permit member insurers to recover assessments paid through full or partial premium tax offsets. These charges neither relate to the ordinary course of the Company’s business nor reflect the Company’s underlying business performance, but result from external situations not controlled by the Company. The Company excludes any charges associated with U.S. guaranty fund assessments and the corresponding tax benefit or expense from adjusted earnings.

In Japan, the government also requires the insurance industry to contribute to a policyholder protection corporation that provides funds for the policyholders of insolvent insurers; however, these costs are calculated and administered differently than in the U.S. In Japan, these costs are not directly related to specific insolvencies or bankruptcies, but are rather a regular operational cost for an insurance company. Based on this structure, the Company does not remove the Japan policyholder protection expenses from adjusted earnings.

Nonrecurring items also include conversion costs related to legally converting the Company's Japan business to a subsidiary; these costs primarily consist of expenditures for legal, accounting, consulting, integration of systems and processes and other similar services. These Japan branch conversion costs were an immaterial amount for the year-ended December 31, 2019 and $75 million for the year-ended December 31, 2018.

Income Taxes

The Company's combined U.S. and Japanese effective income tax rate on pretax earnings was 25.7% in 2019 and 26.7% in 2018. The decrease in the U.S. federal statutory corporate income tax rate from 35% to 21% effective January 1, 2018 drove the reduction in the effective tax rate for 2019 and 2018. Total income taxes were $1.1 billion in both 2019 and 2018. Japanese income taxes on Aflac Japan's results account for most of the Company's consolidated income tax expense.

Foreign Currency TranslationDistribution Channels

Traditional Sales ChannelThis distribution channel includes individual agencies, independent corporate agencies and affiliated corporate agencies. Aflac Japan’s premiumsJapan was represented by more than 9,000 sales agencies at the end of 2019, with more than 109,000 licensed sales associates employed by those agencies, including individual agencies.

BanksConsumers in Japan rely on banks to provide not only traditional bank services, but also as one key source to provide insurance solutions and other services. By the end of 2019, Aflac Japan had agreements with approximately 90% of the total number of banks in Japan to sell its products.

Dai-ichi LifeAflac Japan's alliance with Dai-ichi Life was launched in 2001, and approximately half40,000 Dai-ichi Life representatives offer Aflac's cancer products.

Japan Post GroupAflac Japan's alliance with Japan Post Group was launched in 2008. After the alliance strengthened in 2013, the number of postal outlets of Japan Post Co. Ltd. (JPC) selling Aflac Japan's cancer product increased to more than 20,000 since 2015. Japan Post Insurance Co., Ltd. (JPI) offers Aflac Japan cancer products through its 76 directly managed sales offices. In 2018, the Company’ entered a strategic alliance with Japan Post Holdings Co., Ltd. (Japan Post Holdings), the parent company of Japan Post Co. Ltd (JPC) and Japan Post Insurance Co., Ltd. (JPI). See the "Aflac Japan Segment" subsection of MD&A for more about this alliance.

Daido LifeIn 2013, Aflac Japan and Daido Life Insurance entered into an agreement for Daido to sell Aflac Japan's cancer insurance products specifically to the Hojinkai market, which is an association of small businesses. Currently, Daido also sells Aflac Japan's cancer insurance products to the market in the tax payment association, which is a not-for-profit association for small businesses to support tax related matters.

Competition

The Company competes with other insurance carriers through policyholder service, price, product design and sales efforts, as the number of insurance companies offering stand-alone cancer and medical insurance has more than doubled since the deregulation of the Japan market in 2001. However, based on Aflac Japan's growth of annualized premiums in force and diversified distribution network, the Company does not believe that Aflac Japan's market-leading position has been significantly impacted by increased competition. Furthermore, the Company believes the continued development and maintenance of operating efficiencies will allow Aflac Japan to offer affordable products that appeal to consumers. The Company believes Aflac Japan will remain a leading provider of cancer and medical insurance coverage in Japan, principally due to its experience in the market, well-known brand, low-cost operations, expansive marketing system and product expertise.

Regulation

Financial Services Agency (FSA) The financial and business affairs of Aflac Japan are subject to examination by Japan's FSA. Aflac Japan files annual reports and financial statements for the Japanese insurance operations based on a March 31 fiscal year end, prepared in accordance with Japanese regulatory accounting practices prescribed or permitted by the FSA. Japanese regulatory basis earnings are determined using accounting principles that differ materially from U.S. generally

4





accepted accounting principles (U.S. GAAP). Capital and surplus of Aflac Japan, based on Japanese regulatory accounting practices, was $7.8 billion at December 31, 2019, compared with $6.4 billion at December 31, 2018. Two FSA regulations applicable to Aflac Japan are outlined below.

Privacy and Cybersecurity
With regard to personal information obtained from policyholders, the insured, or others, Aflac Japan is regulated in Japan by the Act on the Protection of Personal Information (APPI) and guidelines issued by FSA and other governmental authorities. The FSA updated its guidelines regarding cybersecurity in October 2018.

FSA Solvency Standard
The FSA maintains a solvency standard, the solvency margin ratio (SMR), which is used by Japanese regulators to monitor the financial strength of insurance companies. As of December 31, 2019, Aflac Japan's SMR was 1,043%, compared with 965% at December 31, 2018. Aflac Japan's SMR is sensitive to interest rate, credit spread and foreign exchange rate changes. See the Liquidity and Capital Resources section of the MD&A for a discussion of measures the Company has taken to mitigate the sensitivity of Aflac Japan's SMR.

Japan Company LawAs abranch of Aflac prior to April 1, 2018, Aflac Japan repatriated a portion of its investment incomeaccumulated earnings, as determined on a Japanese regulatory accounting basis, to Aflac U.S. provided that Aflac Japan had determined that it adequately protected policyholders' interests as measured by its SMR. After the conversion of Aflac Japan to a subsidiary structure on April 1, 2018 and starting in the fourth quarter of 2018, Aflac Japan distributes dividends to the Parent Company. Such dividends are received in yen. Claims and most expenses are paid in yen, andsubject to permitted dividend capacity under the Japan Company purchases yen-denominated assets and U.S. dollar-denominated assets, which may be hedged to yen, to support yen-denominated policy liabilities. These and other yen-denominated financial statement items are, however, translated into U.S. dollarsLaw.

Policyholder ProtectionThe Japanese insurance industry has a policyholder protection corporation that provides funds for financial reporting purposes.the policyholders of insolvent insurers. For additional information, see the policyholder protection section of the MD&A.

Japan
Aflac Japan's insurance products are designed to help consumers pay for medical and nonmedical costs that are not reimbursed under Japan's national health insurance system. Changes in Japan's economy and an aging population have put increasing pressure on Japan's national health care system. As a result, more costs have been shifted to Japanese consumers, who in turn have become increasingly interested in insurance products that help them manage those costs. Aflac Japan has responded to this consumer need by enhancing existing products and developing new products.
The foundation of Aflac Japan's product portfolio has been, and continues to be, its third sector cancer and medical insurance products. Aflac pioneered the cancer insurance market in Japan in 1974, and remains the number one provider of cancer insurance in Japan today. Over the years, Aflac Japan has customized its cancer insurance product to respond to, and anticipate, the needs of its consumers and the advances in medical treatments. The cancer insurance plans the Company offers in Japan provide a lump-sum benefit upon initial diagnosis of internal cancer and benefits for treatment received due to internal cancer such as fixed daily benefits for hospitalization, outpatient services and convalescent care, and surgical benefits. In September 2014, Aflac Japan introduced New Cancer DAYS, a new cancer insurance product which provides enhanced coverage, including outpatient treatments and multiple cancer occurrence benefits. At the same time, premiums for this product have been lowered for most ages compared to prior plans. In October 2014, Aflac Japan introduced a unique Aflac-branded cancer insurance product for Japan's postal system, Japan Post (see the Distribution - Japan section for background information). In March 2016, Aflac Japan launched a cancer insurance product that offers protection to customers who have survived cancer. As the number one provider of cancer insurance in Japan, the Company believes these products further strengthen its brand, and most importantly, provide valuable benefits to consumers who are looking for solutions to manage cancer-related costs.

In early 2002, Aflac Japan introduced EVER, a stand-alone, whole-life medical insurance product which offers a basic level of hospitalization coverage with an affordable premium. Since its initial introduction, Aflac Japan has expanded its suite of EVER product offerings to appeal to specific types of Japanese consumers and achieve greater market penetration. In June 2015, Aflac Japan upgraded its EVER insurance product to include riders to be associated with three critical illnesses (cancer, heart attack, and stroke) to better respond to consumer’s needs for coverage of serious illnesses. These riders provide policyholders with a benefit upon the diagnosis for those three critical illnesses, waiver of premium payment thereafter and unlimited hospital days for such critical illnesses. In 2007, Gentle EVER, Aflac Japan's non-standard medical insurance product, was introduced. This product was designed to meet the needs of certain consumers who cannot qualify for the base EVER plan. The latest version was introduced in March 2016 to enhance its alignment with changing customer needs. In February 2017, Aflac Japan revised the EVER product by introducing riders for lump-sum hospitalization benefits and surgeries for female-specific diseases as well as strengthening outpatient benefits and reducing premiums centered on the young- to middle-aged market segments. This product also offers a short-pay premium period to policyholders.

The Company believes that the affordable cancer and medical insurance products Aflac Japan provides will continue to be an important part of its product portfolio. Nevertheless, as the Company continues its long history of product innovation, Aflac Japan's product portfolio has expanded beyond traditional health-related products.

In July 2016, Aflac Japan launched a new third sector product called Income Support Insurance. This product provides fixed-benefit amounts in the event that a policyholder is unable to work due to significant illness or injury and was developed to supplement the disability coverage within Japan’s social security system. This product targets young to middle-aged consumers, and by focusing efforts on this demographic, Aflac Japan believes it is building relationships that lay the groundwork for the sale of its cancer and medical insurance later in life to the Income Support policyholders.

While Aflac Japan continues to offer life insurance and other first sector products, Aflac Japan has decreased sales of first sector savings products, such as WAYS, child endowment and annuities, in light of the negative interest-rate environment in Japan. Aflac Japan continues to monitor interest rates and their effects on its first sector business. Aflac Japan believes that the measures taken to date, including lowering assumed interest rates or increasing premiums, are appropriate in response to interest rates and that life insurance continues to provide cross-selling opportunities for its third sector products such as cancer and medical insurance. Some of the life insurance products that the Company offers in Japan provide death benefits and cash surrender values. These products are available as stand-alone policies and riders, providing a mix of term and whole life coverage. Aflac Japan's WAYS insurance product has features that allow policyholders to convert a portion of their life insurance to medical, nursing care, or fixed annuity benefits at a predetermined age. In November 2016, Aflac Japan lowered the assumed interest rate for WAYS reflecting the continued low interest rate environment, consistent with its desire to de-emphasize first-sector sales and bolster profitability. Also in November 2016, Aflac Japan halted the offering of traditional fixed-income annuities. Aflac Japan's child endowment insurance product offers a death benefit until a child reaches age 18. It also pays a lump-sum benefit at the time of the child's entry into high school, as well as an educational annuity for each of the four years during his or her college education. In January 2017, Aflac Japan increased the premium level of this product reflecting the continued low interest rate environment.

Aflac Japan continues to proactively sell first sector protection-type products, which include term and whole life, to provide Aflac Japan’s traditional sales channels with a more comprehensive product portfolio to continue to cross-sell with third sector products.

For additional information on Aflac Japan's products and composition of sales, see the Aflac Japan Segment subsection of MD&A in this report.

U.S.
The Company designs its U.S. insurance products to provide supplemental coverage for people who already have major medical or primary insurance coverage. Most of Aflac's U.S. policies are individually underwritten and marketed through independent agents. Additionally, Aflac U.S. started to market and administer group insurance products in 2009.

coverage, as Aflac U.S. insurance policies pay benefits regardless of other insurance. Most of the Aflac U.S. products are distributed in the individual and group supplemental insurance benefits are paid in cash directly to policyholders; therefore, customers have the opportunity to use this cash to help with expenses of their choosing. Aflac U.S. individually issuedmarkets. Aflac's individual policies are portable, andmeaning that individuals may retain their full insurance coverage upon separation from employment or affiliation with a group, generally at the same premium. Individual policies are typically guaranteed-renewable for the lifetime of the policyholder (to age 75 for short-term disability policies).

Life (Term and Whole)Aflac U.S. also offers term- and whole-life policies on both an individual and group basis.


Distribution Channels

Independent Associates/Career AgentsThe career agent channel in Aflac U.S. focuses on marketing Aflac to the small business market, defined as employers of between three and 99 employees. Sales associates in the U.S. are independent contractors and are paid commissions and other variable compensation based on first-year and renewal premiums from their sales of insurance products.

BrokersThe broker channel of Aflac U.S. focuses on selling to the mid- and large-case market, which is comprised of employers with 100 or more employees and typically an average size of 1,000 employees or more. Brokers in the U.S. are independent contractors and are paid commissions based on first-year and renewal premiums from their sales of insurance products.

Aflac U.S. concentrates on marketing its insurance products at the worksite. This method offers policies to individuals through employment, trade and other associations. Aflac U.S. believes that worksite marketing enables sales associates and brokers to reach a greater number of prospective policyholders and lowers distribution costs, compared with individually marketed business. Aflac U.S. is also expanding its distribution strategy to reach consumers outside of the traditional worksite through digital lead generation.

Competition

Aflac U.S. competes against several supplemental insurance carriers on a national and regional basis. Aflac U.S. believes its policies, premium rates, platforms, value-added services and sales commissions are competitive by product type. Moreover, Aflac U.S. believes that its products are distinct from competitive offerings given its product focus (including features, benefits and claims service model), distribution capabilities and brand awareness. 

Since Aflac products provide an additional level of financial protection for policyholders, the Company believes the increased financial exposure some employees may face creates a favorable opportunity for Aflac U.S. products. However, given the profitability erosion some major medical carriers are facing in their core lines of business, the Company has seen a more competitive landscape as these carriers seek entry into Aflac's supplemental product segments and leverage their core benefit offerings by bundling and discounting products in order to gain market share.

One Day PaySM is a claims initiative that Aflac U.S. has focused on to process, approve and pay eligible claims in just one day. The Company believes that this claims practice enhances the Aflac U.S. brand reputation and the trust policyholders have in Aflac, and it helps Aflac stand out from competitors.

Regulation

Insurance RegulationThe Parent Company and its U.S. insurance subsidiaries, Aflac, CAIC, TOIC (Nebraska-domiciled insurance companies) and Aflac New York (a New York-domiciled insurance company) are subject to state regulations in the U.S. as an insurance holding company system. Such regulations generally provide that transactions between companies within the holding company system must be fair and equitable. In addition, transfers of assets among such affiliated companies, certain dividend payments from insurance subsidiaries and certain transactions between companies within the system, including management fees, loans and advances are subject to prior notice to, or approval by, state regulatory authorities. These laws generally require, among other things, the insurance holding company and each insurance company directly owned by the holding company to register with the insurance departments of their respective domiciliary states and to furnish annually financial and other information about the operations of companies within the holding company system.


6





Like all U.S. insurance companies, Aflac, Aflac New York, CAIC and TOIC are subject to regulation and supervision in the jurisdictions in which they do business. In general, the insurance laws of the various jurisdictions establish supervisory agencies with broad administrative powers relating to, among other things:

granting and revoking licenses to transact business
regulating trade and claims practices
licensing of insurance agents and brokers
approval of policy forms and premium rates
standards of solvency and maintenance of specified policy benefit reserves and minimum loss ratio requirements
capital requirements
limitations on dividends to shareholders
the nature of and limitations on investments
deposits of securities for the benefit of policyholders
filing of financial statements prepared in accordance with statutory insurance accounting practices prescribed or permitted by regulatory authorities
periodic examinations of the market conduct, financial, and other affairs of insurance companies

The insurance laws of Nebraska that govern Aflac's activities provide that the acquisition or change of “control” of a domestic insurer or of any person that controls a domestic insurer cannot be consummated without the prior approval of the Nebraska Department of Insurance (NDOI). A person seeking to acquire control, directly or indirectly, of a domestic insurance company or of any person controlling a domestic insurance company (in the case of Aflac, CAIC and TOIC, the Parent Company) must generally file with the NDOI an application for change of control containing certain information required by statute and published regulations and provide a copy to Aflac. In Nebraska, control is generally presumed to exist if any person, directly or indirectly, acquires 10% or more of an insurance company or of any other person or entity controlling the insurance company. The 10% presumption is not conclusive and control may be found to exist at less than 10%. Similar laws apply in New York, the domiciliary jurisdiction of Aflac's New York insurance subsidiary.

State insurance departments conduct periodic examinations of the books and records, financial reporting, policy filings and market conduct of insurance companies domiciled in their states, generally once every three to five years. Examinations are generally carried out in cooperation with the insurance departments of other states under guidelines promulgated by the National Association of Insurance Commissioners (NAIC). In 2016, full-scope, risk-focused financial examinations were conducted by the NDOI, New York Department of Financial Services (NYDFS), and the South Carolina Department of Insurance (SCDOI) on their state domiciled insurance entities Aflac, Aflac New York, and CAIC, respectively. There were no material findings contained in the final exam reports. CAIC redomiciled to Nebraska as of December 2016 and TOIC redomiciled to Nebraska effective March 11, 2019. The NDOI and NYDFS are scheduled to conduct a full-scope comprehensive financial examination covering years 2016-2019 in 2020.

NAIC Risk-Based CapitalThe NAIC continually reviews regulatory matters, such as risk-based capital (RBC) modernization, group capital calculations, liquidity risk assessment and principle-based reserving. The NAIC has adopted a valuation manual containing a principle-based approach to calculation of life insurance reserves. The valuation manual became effective January 1, 2017. There is a three-year transition period, beginning January 1, 2017, during which companies can choose on a product by product basis to implement principle-based reserving for new business. The Company anticipates that the adoption of this manual will not cause a material impact on the statutory reserves of Aflac, Aflac New York, CAIC or TOIC. The NAIC uses an RBC formula relating to insurance risk, business risk, asset risk and interest rate risk to facilitate identification by insurance regulators of inadequately capitalized insurance companies based upon the types and mix of risk inherent in the insurer's operations. The formulas for determining the amount of RBC specify various weighting factors that are applied to financial balances or various levels of activity based on the perceived degree of risk. Regulatory compliance is determined by a ratio of a company's regulatory total adjusted capital to its authorized control level RBC as defined by the NAIC. Companies below specific trigger points or ratios are classified within certain levels, each of which requires specified corrective action. The levels are company action, regulatory action, authorized control, and mandatory control. As of December 31, 2019, based on year-end statutory accounting results, Aflac's company action level RBC ratio was 539%. The 2018 RBC as filed is lower than Aflac U.S. stand-alone RBC due to the inclusion of Aflac Japan for the first quarter of 2018. The RBC charge reflects the business risk without any total adjusted capital (TAC). Aflac's NAIC RBC ratio remains high and reflects a very strong capital and surplus position.

Guaranty Association and Similar ArrangementsUnder state insurance guaranty association laws and similar laws in international jurisdictions, the Company is subject to assessments, based on the share of business the Company writes in the relevant jurisdiction, for certain obligations of insolvent insurance companies to policyholders and claimants. In the U.S., some states permit member insurers to recover assessments paid through full or partial premium tax offsets. The Company's policy is to accrue assessments when the entity for which the insolvency relates has met its state of domicile's statutory

7





definition of insolvency, the amount of the loss is reasonably estimable and the related premium upon which the assessment is based is written. In most states, the definition is met with a declaration of financial insolvency by a court of competent jurisdiction.

Federal InitiativesFederal legislation and administrative policies in several areas, including health care reform legislation, financial services reform legislation, securities regulation, pension regulation, privacy, tort reform legislation and taxation, can significantly and adversely affect insurance companies. Federal regulations applicable to Aflac U.S. are outlined below.

Affordable Care Act (ACA)
The ACA, federal health care reform legislation, gave the U.S. federal government direct regulatory authority over the business of health insurance. The reform included major changes to the U.S. health care insurance marketplace. The ACA, as enacted, does not require material changes in the design of the Company's insurance products. However, indirect consequences of the legislation and regulations could present challenges that could potentially have an impact on the Company's sales model, financial condition and results of operations. The U.S. Congress has considered and may continue to consider legislation that would repeal and replace key provisions of the ACA. There can be no assurance that any legislation affecting the ACA will be passed by Congress, nor as to the ultimate timing or provisions of any such legislation, nor as to the effect of any such legislation on the design or marketability of the Company's insurance products. Further, certain provisions of the ACA have been and may continue to be subject to challenge through litigation, the ultimate effects of which on the ACA are uncertain.

Dodd-Frank Act
Title VII of the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 (Dodd-Frank) and regulations issued thereunder, in particular rules to require central clearing for certain types of derivatives, may have an impact on the Company's derivative activity, including activity on behalf of Aflac Japan. In addition, in 2015 and 2016, six U.S. financial regulators, including the U.S. Commodity Futures Trading Commission (CFTC), issued final rules regarding the exchange of initial margin (IM) and variation margin (VM) for uncleared swaps that impose greater obligations on swap dealers regarding uncleared swaps with certain counterparties, such as the Company. The requirements of such rules with respect to IM are currently being phased in and will be fully implemented by September 1, 2020, although an extension to September 1, 2021 is expected for covered entities with an aggregate average notional amount below $50 billion. The margin requirements are expected to result in more stringent collateral requirements and to affect other aspects of the Company's derivative activity.

The Dodd-Frank Act also established a Federal Insurance Office (FIO) under the U.S. Treasury Department to monitor all aspects of the insurance industry and of lines of business other than certain health insurance, certain long-term care insurance and crop insurance. Traditionally, U.S. insurance companies have been regulated primarily by state insurance departments. The FIO does not directly regulate the insurance industry, but under Dodd-Frank it has the power to preempt state insurance regulations that are inconsistent with international agreements reached by the federal government, subject to certain requirements and restrictions. The FIO and certain federal agencies must achieve consensus positions with the state insurance regulators when taking positions on insurance proposals by certain international forums. The President and Congress have stated proposals to reform or repeal certain provisions of the Dodd-Frank Act, some of which have been implemented. The Company cannot predict with any degree of certainty what impact, if any, such proposals might have on Aflac's business, financial condition, or results of operations.

Privacy and Cybersecurity
The collection, maintenance, use, protection, disclosure and disposal of individually identifiable data by the Company's businesses are regulated at the international, federal and state levels. These laws and rules are subject to change by legislation or administrative or judicial interpretation. Various state laws address the unauthorized access and acquisition of personal information and the use and disclosure of individually identifiable health data to the extent they are more restrictive than those contained in the privacy and security provisions in the federal Gramm-Leach-Bliley Act of 1999 (GLBA) and in the Health Insurance Portability and Accountability Act of 1996 (HIPAA). For example, the California Consumer Privacy Act became effective January 1, 2020 and requires businesses to provide California consumers rights to access, delete, and restrict certain uses of their personal information. Under the law, the California Attorney General may not bring an enforcement action prior to July 1, 2020. HIPAA also requires that the Company imposes privacy and security requirements on its business associates (as such term is defined in the HIPAA regulations).

Cybersecurity also continues to be an area of evolving focus for U.S. legislation and regulatory activity. In March 2017, new cybersecurity regulation issued by the NYDFS went into effect that requires covered entities, including Aflac New York, to maintain an information security program meeting certain security, data disposal, audit, activity

8





monitoring, and data encryption requirements. In October 2017, the NAIC adopted an Insurance Data Security Model Law that may be adopted in whole or in part by U.S. states in which the Company’s subsidiaries are licensed. Other states have adopted and, the Company expects, will continue to pass legislation and issue regulations related to cybersecurity. The Company anticipates, assesses and if necessary modifies its information security program to accommodate such changes.

ITEM 1A. RISK FACTORS
The Company faces a wide range of risks, and its continued success depends on its ability to identify, prioritize and appropriately manage enterprise risk exposures. Readers should carefully consider each of the following risks and all of the other information set forth in this Form 10-K. These risks and other factors may affect forward-looking statements, including those in this document or made by the Company elsewhere, such as in earnings release webcasts, investor conference presentations or press releases. The risks and uncertainties described herein may not be the only ones facing the Company. Additional risks and uncertainties not presently known to the Company or that the Company currently believes to be immaterial may also adversely affect its business. If any of the following risks and uncertainties develops into actual events, there could be a material impact on the Company.
Sales of the Company's products and compositionservices are dependent on its ability to attract, retain and support a network of qualified sales associates, brokers and employees in the U.S. and sales associates and other distribution partners in Japan.

The Company's sales, results of operations and financial condition could be materially adversely affected if its sales networks deteriorate or if the Company does not adequately provide support, training and education for its existing network of sales associates, brokers, other distribution partners and employees. In the U.S., competition exists for sales associates and brokers with demonstrated ability. In Japan, the Company's sales results are dependent upon its relationship with sales associates and other distribution partners, including its strategic partner, Japan Post.

The Company competes with other insurers and financial institutions primarily on the basis of its products, compensation, support services and financial rating. The Company's sales associates, brokers and other distribution partners are independent contractors and may sell products of its competitors. If the Company's competitors offer products that are more attractive, or pay higher commissions than the Company does, any or all of these distribution partners may concentrate their efforts on selling the Company's competitors' products instead of the Company's. In addition to the Company's commissioned sales force in the U.S., Aflac has expanded its sales leadership team to include a salaried sales force of over 200 market directors and broker sales professionals. The Company's inability to attract and retain qualified sales associates, brokers and other distribution partners, including its alliance partners in Japan, could have a material adverse effect on the Company's sales, results of operations and financial condition.

Additionally, as the Japan and U.S. employment markets continue to evolve, there is risk that the Company's practices regarding attracting, developing, and retaining employees may not be fully effective. Failure to successfully meet and maintain sufficient levels of employees may diminish the Company's ability to achieve its financial and compliance objectives, both of which are time consuming and personnel-intensive.

For more information on the strategic partnership with Japan Post, see the risk factor below entitled, " Events related to the ongoing Japan Post investigation and other matters regarding sales of Japan Post Insurance products could negatively impact the Company’s sales and results of operations."

Events related to the ongoing Japan Post investigation and other matters regarding sales of Japan Post Insurance products could negatively impact the Company’s sales and results of operations

As previously disclosed, in the second half of 2019 and the first quarter of 2020 there have been news reports and public comments regarding improper sales practices relating to sales of JPI products by JPI and JPC, each an affiliate of Japan Post Holdings (together with JPI and JPC, the Japan Post Group). JPC and JPI are important distribution and alliance partners of the Company, which in 2018 collectively accounted for approximately 25% of Aflac Japan’s third sector sales. On July 24, 2019, after such news reports and other public comments, the Japan Post Group announced that they had established a Special Investigative Committee comprised of independent former prosecutors to determine whether JPC and JPI sales practices with respect to JPI products had caused disadvantages to customers holding such policies that were not otherwise the result of honoring such customers’ intentions.

On December 18, 2019, the Japan Post Group issued a release discussing results of the investigation and stating that JPI had identified a number of cases involving potential violation of laws and regulations or internal rules. On the same date, the Japan Post Group stated that it would continue the investigation with a goal of completing it by March 2020. On December 27, 2019, the Japanese FSA issued three-month business suspension orders to JPC and JPI for the sale of JPI insurance products, and the Japan Ministry of Internal Affairs and Communications also issued a three-month business suspension order to JPC for the sale of JPI insurance products. Also on December 27, 2019, the Japan Post Group announced the resignation of the chief executives of Japan Post Holdings, JPC and JPI, to be effective January 5, 2020. On January 31,

11



2020, the Japan Post Group announced that its internal investigation had been expanded to additional policyholders and the investigation would continue with a goal of completing it by the end of June 2020. The Japan Post Group stated they could not comment on the expected timing for it to re-initiate sales of JPI insurance products.

Notwithstanding the JPI investigation and the three-month suspension orders promulgated by the FSA and the Japan Ministry of Internal Affairs and Communications, the sale of Aflac Japan cancer policies has continued through JPC and JPI. However, while the sale of Aflac Japan cancer insurance products is not within the scope of the suspension orders, beginning in August 2019 the Company has experienced a material decrease of sales in the Japan Post Group channel. This decline has continued into 2020. The Company believes that sales of Aflac Japan cancer insurance through JPC and JPI are unlikely to return to 2018 levels in the near term. It is uncertain what long-term effect these developments will have on the Company’s results of operations or financial condition, but any such effects could be material. See the "Aflac Japan Segment" subsection of Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations.

Competition could adversely affect the Company's ability to increase or maintain its market share or profitability.

The Company operates in a competitive environment and in an industry that is subject to ongoing changes from market pressures brought about by customer demands, legislative reform, marketing practices and changes to health care and health insurance delivery. These factors require the Company to anticipate market trends and make changes to differentiate the Company's products and services from those of its competitors. The Company also faces the potential of competition from existing or new companies in the U.S. Segmentand Japan that have not historically been active in the supplemental health insurance industry, but some of which have greater financial, marketing and management resources than the Company does. Further, some of these potential competitors could introduce new means of product development and delivery that disrupt the Company’s business model. Failure to anticipate market trends and/or to differentiate the Company's products and services can affect the Company's ability to retain or grow profitable lines of business. Further, as employers and brokers are increasingly requesting a full-suite of products from one insurance provider, a failure to react and adapt to these demands could result in decreased sales or market share.

The insurance market is undergoing rapid changes with frequent introductions of new technology-driven products and services. The Company's future success will depend, in part, on its ability to keep pace with the technological changes and to use technology to satisfy and grow customer demand for the Company's products and services and to create additional efficiencies in its operations. The Company expects that it will need to continue making substantial investments in its technology and information systems to compete effectively and to stay current with technological changes. The Company may not be able to effectively implement new technology-driven products and services or be successful in marketing these products and services to its customers. A failure to meet evolving customer demands through innovative product development, effective distribution channels, and continuous investment in the Company's technology could result in lower revenues and less favorable policy terms and conditions, which could adversely affect the Company's operating results. As a result, the Company's ability to effectively compete to retain or acquire new business may be impaired, and its business, financial condition or results of operations may be adversely affected.

If future policy benefits, claims or expenses exceed those anticipated in establishing premiums and reserves, the Company's financial results would be adversely affected.

The Company establishes premiums for many of its policies on assumptions for morbidity, mortality, longevity and persistency. The Company also establishes and carries, as a liability, reserves based on estimates of how much will be required to pay for future benefits and claims on its policies. The Company calculates these reserves using various assumptions and estimates, including premiums the Company will receive over the assumed life of the policy; the timing, frequency and severity of the events covered by the insurance policy; and the investment returns on the assets the Company purchases with a portion of its net cash flow from operations.

The assumptions and estimates that the Company uses in establishing premiums and reserves depend on the Company's judgment regarding the likelihood of future events and are inherently uncertain. Many factors can cause actual outcomes to deviate from these assumptions and estimates, such as changes in incidence rates, economic conditions, changes in government healthcare policy, advances in medical technology, changes in treatment patterns, and changes in average lifespan. Accordingly, the Company cannot determine with precision the ultimate amounts that it will pay for, or the timing of payment of, actual benefits and claims or whether the assets supporting the policy liabilities will grow to the level the Company assumes prior to payment of benefits or claims. If the Company's actual experience is different from its assumptions or estimates, the Company's reserves may prove inadequate. As a result, the Company would incur a charge to earnings in the period in which it determines such a shortfall exists, which could have a material adverse effect on the Company's business, results of operations and financial condition.


12



Generally, lower mortality decreases the profitability of third sector products in Japan, as more policyholders will survive into ages where they have a higher rate of claim incidence. This assumption can impact pricing and reserving.  For instance, Japan FSA periodically requires updates to their Standard mortality tables for FSA reserves. An update to the Standard mortality tables was performed in April 2018 applicable to all business issued after that date. For business that is inforce prior to the update, the change in mortality table would not have an impact. For new issues, the updated mortality tables would be included in the Company's reserve assumptions, and slow the emergence of FSA earnings for third sector products and therefore will have an impact on pricing returns. The Company adjusts pricing assumptions as new products are developed to adjust for these mortality assumptions. 

The success of the Company's business depends in part on effective information technology systems and on continuing to develop and implement improvements in technology.

The Company's business depends in large part on its technology systems for interacting with employers, policyholders, sales associates, and brokers, and the Company's business strategy involves providing customers with easy-to-use products to meet their needs and ensuring employees have the technology in place to support those needs. Some of the Company's information technology systems and software are older, legacy-type systems that are less efficient and require an ongoing commitment of significant resources to maintain or upgrade to current standards including adequate business continuity procedures. The Company is in a continual state of upgrading and enhancing its business systems; however, these changes tend to challenge the Company's complex integrated environment. The Company's success is dependent in large part on maintaining or improving the effectiveness of existing systems and continuing to develop and enhance information systems that support its business processes in a cost-efficient manner. If the Company does not maintain the effectiveness of its systems, the Company's operations and reputation could be adversely affected and it could be exposed to litigation as well as to regulatory proceedings and fines or penalties.

Defaults, downgrades, widening credit spreads or other events impairing the value of the fixed maturity securities and loan receivables in the Company's investment portfolio may reduce the Company's earnings and capital position.
The Company is subject to the risk that the issuers and/or guarantors of fixed maturity securities and loan receivables the Company owns may default on principal or interest. A significant portion of the Company's portfolio represents an unsecured obligation of the issuer, including some that may be subordinated to other debt in the issuer’s capital structure. In these cases, many factors can influence the overall creditworthiness of the issuer and ultimately its ability to service and repay the Company's holdings. This can include changes in the global economy, the company's assets, strategy, or management, shifts in the dynamics of the industries in which they compete, their access to additional funding, and the overall health of the credit markets. Factors unique to the Company's securities including contractual protections such as financial covenants or relative position in the issuer's capital structure also influence the value of the Company's holdings.

Most of the Company's investments carry a rating by one or more of the nationally recognized statistical rating organizations (NRSROs or rating agencies). Any change in the rating agencies' approach to evaluating credit and assigning an opinion could negatively impact the fair value of the Company's portfolio. The Company employs a team of credit analysts to monitor the creditworthiness of the issuers in its portfolio. Any credit-related declines in the fair value of positions held in the Company's portfolio believed to be not temporary in nature will negatively impact the Company's net income and capital position through impairment and other credit related losses. These losses would also affect the Company's solvency ratios in the U.S. and Japan. Aflac Japan has certain regulatory accounting requirements for realizing impairments that could be triggered by credit-related losses, which may be different from U.S. GAAP and statutory requirements. These impairment losses could negatively impact Aflac Japan's earnings, and the corresponding dividends and capital deployment.

The Company is also subject to the risk that any collateral providing credit enhancement to the Company's positions could deteriorate. These instruments may include senior secured first lien loans, such as commercial mortgage loans, bank loans, middle market loans, and loan-backed securities where the underlying loan or collateral notes may default on principal, interest, or other payments, causing an adverse change in cash flows to the positions held in the Company's investment portfolio.

The Company is exposed to sovereign credit risk through instruments issued directly by governments and government entities as well as banks and other institutions that rely in part on the strength of the underlying government for their credit quality. In addition to the U.S. and Japan, many governments, especially in Europe, have been subject to rating downgrades due to the need for fiscal and budgetary remediation and structural reforms, reduced economic activity, and investment needed to support banks or other systemically important entities. Additional downgrades or default of the Company's sovereign issuers will have a negative impact on its portfolio and could reduce the Company's earnings and capital.


13



In addition to the Company's exposure to the underlying fundamental credit strength of the issuers of its fixed maturity securities and the underlying risk of default, the Company is also exposed to the general movement in credit market spreads. A widening of credit spreads could reduce the value of the Company's existing portfolio, create unrealized losses on its investment portfolio, and reduce the Company's adjusted capital position which is used in determining the SMR in Japan. This widening of credit spreads could, however, increase the net investment income on new credit investments. Conversely, a tightening of credit spreads could increase the value of the Company's existing portfolio and create unrealized gains on its investment portfolio. This tightening of credit spreads could also reduce the net investment income available to the Company on new credit investments. Increased market volatility also makes it difficult to value certain of the Company's investment holdings (see the Critical Accounting Estimates section in Item 7, Management's Discussion and Analysis, of this Form 10-K).

For more information regarding credit risk, see the Credit Risk subsection of Item 7A, Quantitative and Qualitative Disclosures about Market Risk, of this Form 10-K.

The Company is exposed to significant interest rate risk, which may adversely affect its results of operations, financial condition and liquidity.
The Company has substantial investment portfolios that support its policy liabilities. Low levels of interest rates on investments experienced in Japan and the U.S. over the last decade have reduced the level of investment income earned by the Company. The Company's overall level of investment income will be negatively impacted in a persistent low-interest-rate environment. While the Company generally seeks to maintain a diversified portfolio of fixed-income investments that reflects the cash flow and duration characteristics of the liabilities it supports, the Company may not be able to fully mitigate the interest rate risk of its assets relative to its liabilities. The Company's exposure to interest rate risk relates primarily to the ability to invest future cash flows to support the interest rate assumption made at the time the Company's products were priced and the related reserving assumptions were established. A sustained decline in interest rates could hinder the Company's ability to earn the returns assumed in the pricing and the reserving for its products at the time they were sold and issued. Due to low interest rates, the Company's ability to earn the returns it expects may also influence the Company's ability to develop and price attractive new products and could impact its overall sales levels. The Company's first sector products are more interest rate sensitive than third sector products. As discussed in Item 1. Business, beginning in 2013, Aflac Japan began to curtail sales of first sector savings-type products due to persistent low interest rates in Japan. The continuing negative interest rate imposed by the Bank of Japan (BoJ) on excess bank reserves could continue to have a negative impact on the distribution and pricing of these products.
A rise in interest rates could improve the Company's ability to earn higher rates of return on future investments, as well as floating rate investments held in its investment portfolio. However, an increase in the differential of short-term U.S. and Japan interest rates would increase the cost of hedging a portion of the U.S. dollar-denominated assets in the Aflac Japan segment into yen, which could have a material adverse effect on the Company's business, results of operations or financial condition. The Company’s floating rate investments typically bear interest based on the London Interbank Offered Rate (LIBOR). Regulatory and industry initiatives to eliminate LIBOR as an interest rate benchmark may create uncertainty in the valuation of LIBOR-based loans, as well as for other LIBOR-based derivatives and assets. This may adversely impact both pricing and liquidity in such instruments. The Company is unable to predict with certainty how LIBOR elimination may impact markets, pricing, liquidity and other factors or the Company's activities.
Changes in interest rates impact unrealized gains and losses of fixed income securities in the Company's investment portfolio; however, they do not have a direct impact on the related valuation of the corresponding liabilities. Prolonged periods of low interest rates, as have been experienced in recent years, heighten the risk associated with future increases in interest rates because an increasing proportion of the Company's investment portfolio includes investments that bear lower rates of return than the embedded book yield of the investment portfolio. A rise in interest rates could decrease the fair value of the Company's debt securities. Some of the insurance products that Aflac sells in the U.S. and Japan provide cash surrender values. A rise in interest rates could trigger significant policy surrenders, which might require the Company to sell investment assets and recognize unrealized losses. This situation is commonly referred to as disintermediation risk. The Company generally invests its assets to match the duration and cash flow characteristics of its policy liabilities, and therefore would not expect to realize most of these gains or losses, however, the Company's risk is that unforeseen events or economic conditions, such as changes in interest rates resulting from governmental monetary policies, domestic and international economic and political conditions, and other factors beyond the Company's control will reduce the effectiveness of this strategy. These events or economic conditions could either cause the Company to dispose of some or all of these investments prior to their maturity, or increase the risk that the issuers of these securities may default or may require impairment, which could result in the Company having to recognize such gains or losses.

14



Rising interest rates also negatively impact the SMR since unrealized losses on the available-for-sale investment portfolio factor into the ratio. For regulatory accounting purposes for Aflac Japan, there are certain requirements for realizing impairments that could be triggered by rising interest rates, negatively impacting Aflac Japan's earnings and corresponding dividends and capital deployment.
Further, interest rate risk is still an inherent portfolio, business and capital risk for the Company, and significant changes in interest rates could have a material adverse effect on the Company's consolidated results of operations, financial condition or cash flows through realized losses, impairments, changes in unrealized positions, and liquidity.

For more information regarding interest rate risk, see the Interest Rate Risk subsection within the Market Risks of Financial Instruments section of MD&A in this report.


The Company's concentration of business in Japan poses risks to its operations.
The Company's operations in Japan, including realized gains and losses on Aflac Japan's investment portfolio, accounted for 69% of the Company's total revenues in 2019, and 70% in both 2018 and 2017. The Japanese operations accounted for 83% of the Company's total assets at December 31, 2019, compared with 84% at December 31, 2018.

Further, because of the concentration of the Company's business in Japan and its need for long-dated yen-denominated assets, the Company has a substantial concentration of Japan Government Bond (JGBs) in its investment portfolio. As such the Company has material exposure to the Japanese economy, geo-political climate, political regime, and other factors that generally determine a country's creditworthiness. Specifically, the NRSROs, credit rating agencies registered with the SEC, have placed increased scrutiny on JGBs, which are a significant component of the Company’s overall investment portfolio, resulting in downgrades as discussed later in this Risk Factors section. 

The Company seeks to match investment currency and interest rate risk to its yen liabilities. The low level of interest rates available on yen-denominated securities has a negative effect on overall net investment income. A large portion of the cash available for reinvestment each year is deployed in yen-denominated instruments and subject to the low level of yen interest rates.

Any potential deterioration in Japan's credit quality, market access, the overall economy of Japan, or Japanese market volatility could adversely impact the business of Aflac in general and specifically Aflac Japan and its related results of operations and financial condition.

Lack of availability of acceptable yen-denominated investments could adversely affect the Company's results of operations, financial position or liquidity.
The Company attempts to match both the duration and currency of its assets with its liabilities. This is very difficult for Aflac Japan due to the lack of available long-dated yen-denominated fixed income instruments beyond JGBs.

Prior to the onset of the financial crisis of 2008, the Company was focused on investing cash flows in JGBs, which had relatively low yields, and utilizing private placement and perpetual securities to gain additional yield, extend the duration of the investment portfolio, and maintain yen exposure. Given call activity with respect to certain of the Company's legacy private placement investments, the Company has added a modest amount of yen-denominated private placements to its investment portfolio in recent periods. The investment in private placements carries risk associated with illiquidity, which is managed and monitored by the Company.

Starting in 2012, Aflac Japan augmented its investment strategy to include U.S. dollar-denominated investments, some of which could then be hedged back to yen. Initially this program focused on public investment-grade bonds but has evolved over time to include U.S. dollar-denominated investment-grade commercial mortgage loans, middle market loans, infrastructure debt, as well as other loan types, high yield bond and public and private equities. The Company plans to continue adding other instruments denominated in U.S. dollars, including floating rate investments, to improve the portfolio diversification and/or return profile. Some of the U.S. dollar-denominated asset classes that the Company has added, and anticipates continuing to add, have less liquidity than investment-grade corporate bonds. These strategies will continue to increase the Company's exposure to U.S. interest rates, credit spreads and other risks. The Company has increased foreign exchange risk exposure as the comprehensive hedging program may not always correlate to the underlying U.S. dollar-denominated assets, thereby increasing earnings volatility. These risks can significantly impact the Company's consolidated results of operations, financial position or liquidity.


15



Investing in U.S. dollar-denominated investments in Aflac Japan also creates an unmatched foreign currency exposure and related SMR volatility, as Aflac Japan’s insurance liabilities are yen-denominated. Although the Company engages in certain foreign exchange hedging activities to partially mitigate this risk, and such hedged assets may be used to satisfy yen-denominated insurance liabilities and other business obligations, important risks remain.

Foreign exchange derivatives used for hedging are periodically settled, which results in cash receipt or payment at maturity or early termination. Cumulative net cash settlements on derivatives hedging currency exposure of Aflac Japan's U.S. dollar-denominated investments are associated with existing U.S. dollar-denominated investments that continue to be hedged, previously hedged investments that continue to be held but are no longer hedged, as well as, investments previously hedged that have since been sold, matured or redeemed and may or may not have not been converted to yen. The Company’s foreign exchange derivatives are typically shorter-dated than the underlying U.S. dollar-denominated investments being hedged, which creates roll-over risks within the hedging program that could increase the cost of such derivatives. If the Company reduces the notional amount of foreign exchange derivatives prior to the maturity of the hedged U.S. dollar-denominated investments, the foreign exchange gains or losses on the U.S. dollar-denominated investments remain economically unrealized. These foreign currency gains or losses on the investments are only economically realized, or monetized, through sale, maturity or redemption of the investments and concurrent conversion to yen. However, the Company may not realize the benefit of offsetting adverse cash settlements on hedging derivatives with cash receipts on the U.S. dollar-denominated investments if the currency exchange rates move in an adverse direction before the investments are converted to yen, or if the investments are never converted to yen. As an example of the latter, if the Company’s actual insurance risk experience in Japan is as expected or more favorable than expected, the need for yen to pay expenses and claims would correspondingly remain at or below expected levels, thereby diminishing operational requirements to convert U.S. dollar-denominated investments to yen. The settlement of the foreign exchange derivatives is reported in the investing activities section of the Company’s consolidated statements of cash flows in the line item “Settlement of derivatives, net.”

For more information regarding unhedged U.S. dollar-denominated securities, see the risk factor entitled, “The Company is exposed to foreign currency fluctuations in the yen/dollar exchange rate.” For more information regarding Aflac Japan's U.S. dollar-denominated investments and hedging activities, see the "Hedging Activities"subsection within the MD&A of this report, and for more information regarding foreign currency risk, see the "Currency Risk" subsection within the Item 7A. Quantitative and Qualitative Disclosures about Market Risk section in this report.

If the Company fails to comply with restrictions on customer privacy and information security, including taking steps to ensure that its third-party service providers and business associates who access, store, process or transmit sensitive customer information maintain its security, integrity, confidentiality and availability, the Company's reputation and business operations could be materially adversely affected.

The collection, maintenance, use, protection, disclosure and disposal of individually identifiable data by the Company's businesses are regulated at the international, federal and state levels. These laws and rules are subject to change by legislation or administrative or judicial interpretation. Various state laws address the unauthorized access and acquisition of personal information and the use and disclosure of individually identifiable health data to the extent they are more restrictive than those contained in the privacy and security provisions in the federal GLBA and in the HIPAA. HIPAA also requires that the Company imposes privacy and security requirements on its business associates (as such term is defined in the HIPAA regulations). With regard to personal information obtained from policyholders, the insured, or others, Aflac Japan is regulated in Japan by the APPI and guidelines issued by FSA and other governmental authorities.

The Company relies on third parties, and in some cases subcontractors, to provide information technology and data services. It also relies on various parties in its distribution channels including agencies, banks and Japan Post in Japan, as well as sales associates and brokers in the U.S., to provide services to prospective and existing customers. Although the Company provides for appropriate protections through its contracts and performs information security risk assessments of its third-party service providers and business associates, the Company still has limited control over their actions and practices. In addition, despite the security measures the Company has in place to ensure compliance with applicable laws and rules, the Company's facilities and systems, and those of the Company's third-party providers and participants in its distribution channels may be vulnerable to security breaches, acts of vandalism or theft, computer viruses, misplaced or lost data, programming and/or human errors or other similar events. From time to time, the Company, its third party providers and participants in the Company’s distribution channels have experienced and will likely continue to experience such events. In such cases, notification to affected individuals, state and federal regulators, state attorneys general and media may be required, depending upon the number of affected individuals and whether personal information including health or financial data was subject to unauthorized access.

The U.S. Congress and many states are considering new privacy and security requirements that would apply to the Company's business. Compliance with new privacy and security laws, requirements, and new regulations may result in cost

16



increases due to necessary systems changes, new limitations or constraints on the Company's business models, the development of new administrative processes, and the effects of potential noncompliance by the Company's business associates. They also may impose further restrictions on the Company's collection, disclosure and use of customer identifiable data that are housed in one or more of the Company's administrative databases. Noncompliance with any privacy laws or any security breach involving the misappropriation, loss, theft or other unauthorized disclosure of sensitive or confidential customer information, whether by the Company or by one of its third parties, could have a material adverse effect on the Company's business, reputation, brand and results of operations, including: material fines and penalties; compensatory, special, punitive and statutory damages; consent orders regarding the Company's privacy and security practices; adverse actions against the Company's licenses to do business; and injunctive relief.

In addition, under Japanese laws and regulations, including the APPI, if a leak or loss of personal information by Aflac Japan or its business associates should occur, depending on factors such as the volume of personal data involved and the likelihood of other secondary damage, Aflac Japan may be required to file reports to the FSA; issue public releases explaining such incident to the public; or become subject to an FSA business improvement order, which could pose a risk to the Company's reputation.

Interruption in telecommunication, information technology and other operational systems, or a failure to maintain the security, confidentiality, integrity or privacy of sensitive data residing on such systems, could harm the Company's business.

The Company stores confidential policyholder, employee, agent, and other proprietary information on its information technology systems. In addition, the Company depends heavily on its telecommunication, information technology and other operational systems and on the integrity and timeliness of data it uses to run its businesses and service its customers. These systems may fail to operate properly or become disabled as a result of events or circumstances wholly or partly beyond the Company's control. Additionally, design flaws may exist in certain systems, processes, software, or configurations that in turn may result in system failure, data corruption, or compromise. Despite the Company's implementation of a variety of security measures to defend against threats incurred on a daily basis, its information technology and other systems, as well as those of third party providers and participants in the Company’s distribution channels, have been and will likely continue to be subject to physical or electronic break-ins, unauthorized tampering, security breaches or other cyber-attacks, that may result in the failure to adequately maintain the security, confidentiality, integrity, or privacy of sensitive data, including personal information relating to customers and prospective customers, or in the misappropriation of the Company's intellectual property or proprietary information.

From time to time, the Company, its third party providers and participants in the Company’s distribution channels have experienced and will likely continue to experience such events. Although the minor data leakage issues the Company has experienced to date have not had a material effect on its business, there is no assurance that the Company's security systems or processes will prevent or mitigate future break-ins, tampering, security breaches or other cyber-attacks. Interruption in telecommunication, information technology and other operational systems, or a failure to maintain the security, confidentiality or privacy of sensitive data residing on such systems, whether due to actions by the Company or others, including third party providers and participants in the company’s distribution channels, could delay or disrupt the Company's ability to do business and service its customers, seriously harm the Company's brand and reputation as well as the Company's ability to compete effectively, subject it to regulatory sanctions and other claims, lead to a loss of customers and revenues and otherwise adversely affect the Company's business. In addition, the costs to address or remediate system interruptions or security threats and vulnerabilities, whether before or after an incident, could be significant.

While the Company continues to invest in the infrastructure of its data security programs, the Company, as well as its third party providers and participants in the Company’s distribution channels, have been, and will likely continue to be, the target of unauthorized access, social engineering, phishing, cyber-attacks, web application attacks, computer viruses or other malicious codes, or other computer-related penetrations. Although the Company attempts to manage its exposure to such events through the purchase of cyber liability insurance, such events are inherently unpredictable and insurance may not be sufficient to protect the Company against all losses. As a result, events such as these could adversely affect the Company's financial condition or results of operation.

Catastrophic events could adversely affect the Company's financial condition and results of operations as well as the availability of the Company’s infrastructure and systems.

The Company's insurance operations are exposed to the risk of catastrophic events including, but not necessarily limited to, epidemics, pandemics, tornadoes, hurricanes, earthquakes, tsunamis, war or other military action, and terrorism or other acts of violence. The extent of losses from a catastrophe is a function of both the total amount of insured exposure in the area affected by the event and the severity of the event. Certain events such as earthquakes, tsunamis, hurricanes and man-made catastrophes could cause substantial damage or loss of life in larger areas, especially those that are heavily populated. Claims resulting from natural or man−made catastrophic events could cause substantial volatility in the Company's financial results for any fiscal quarter or year and could materially reduce its profitability or harm the Company's financial condition, as well as affect its ability to write new business.

Additionally, the Company's business operations may be adversely affected by such catastrophic events to the extent they disrupt the Company's physical infrastructure, human resources or systems that support its businesses and customers. Although the Company has a global crisis management framework to minimize the business disruption from a catastrophic event, such framework may not be effective to avoid an adverse impact to the Company from such an event.

Difficult conditions in global capital markets and the economy could have a material adverse effect on the Company's investments, capital position, revenue, profitability, and liquidity and harm the Company's business.
The Company's results of operations are materially affected by conditions in the global capital markets and the global economy generally, including in its two primary operating markets of the U.S. and Japan. Weak global financial markets impact the value of the Company's existing investment portfolio, influence opportunities for new investments, and may contribute to generally weak economic fundamentals, which can have a negative impact on its operating activities.

In recent years, global capital markets have been severely impacted by several major events. The financial crisis that began in the latter part of 2008 saw dramatic declines in investment values and weak economic conditions as the global financial system came under extreme pressure. Although U.S. markets began recovering in late 2009 and 2010, Europe continued to struggle under a severely weakened banking system and investor concerns with sovereign debt levels. Following a period of unprecedented intervention by governments and central banks, including the U.S. Federal Reserve and European Central Bank (ECB), financial conditions improved from the dire conditions of the global financial crisis, global recession, and European debt crisis. More recently, global markets have experienced bouts of volatility due to uncertainty surrounding a British exit from the European Union, Japan’s continued recovery amidst assorted policy changes, volatility in global commodity prices including oil, divergent monetary policies in the U.S. versus many other developed economies, heightened concerns surrounding the Chinese economy and increasing protectionism in U.S. foreign trade policy. While capital and market conditions have been generally favorable in the last year, the prospect for increased volatility remains.

A shift in the global trading policies by the U.S. and subsequent trade conflict with China has raised concerns about a slowdown of the Chinese economy and the recent trade agreement between the U.S. and China left tariffs in place and many trade issues unresolved. In addition, the recent trade agreement between the U.S. and Japan resulted in tariff reductions on some products but left tariffs on other products in place. While it is not expected that the Company's products would be directly impacted by tariffs, any resulting economic downturn could adversely affect the Company.

Activity by the government of North Korea in 2018 was the subject of increasing focus for a number of other governments, including those of the U.S. and Japan. Although hostile rhetoric decreased in 2019, there is a possibility of renewed hostility between their governments. In addition, in January 2020, hostility between the government of the U.S. and the government of Iran increased, ultimately culminating in a number of missile strikes. Such activity and related geopolitical risk could have a significant impact on financial market conditions across the world. Under certain circumstances, government actions taken in response to these or similar situations could have a material impact on the Company's operations and financial performance, including the indirect impact of potentially severe and prolonged capital market volatility and disruption.

As the Company holds a significant amount of fixed maturity securities issued by borrowers located in many different parts of the world, including a large portion issued by banks and financial institutions, sovereigns, and other corporate borrowers in the U.S. and Europe, its financial results are directly influenced by global financial markets. A retrenchment of the recent strength of the capital markets could adversely affect the Company's financial condition, including its capital position and overall profitability. Market volatility and recessionary pressures could result in significant realized or unrealized losses due to severe price declines driven by increases in interest rates or credit spreads, defaults in payment of principal or interest, or credit rating downgrades.

Following the election of Shinzo Abe as Prime Minister of Japan in December 2012, the new administration adopted a new set of financial measures to stimulate the Japanese economy, including imposing negative interest rates on excess bank reserves. In December 2014 and October 2017 snap-elections, the ruling Liberal Democratic Party (LDP) won decisive victories further strengthening Mr. Abe's ability to continue with economic reforms and address key policy challenges. In September 2018, Mr. Abe won reelection to another three-year term as president of the LDP. Most recently, the BoJ signaled to hold its policy rate at zero and to continue yield curve control to maintain a targeted yield on the 10-year JGB. Prime Minister Abe’s election victories may result in the continuation of current monetary policy, but there can be no guarantee that this is the case.

Japan is the largest market for the Company's products, and the Company owns substantial holdings in JGBs. Government actions to stimulate the economy affect the value of the Company's existing holdings, its reinvestment rate on new investments in JGBs or other yen-denominated assets, and consumer behavior relative to the Company's suite of products. The additional government debt from fiscal stimulus actions could adversely impact the Japan sovereign credit profile, which could in turn lead to volatility in Japanese capital and currency markets.

The Company's investment portfolio has sizeable credit positions in many other geographic areas of the world including the Middle East, Latin America, Asia, and other emerging markets. Deterioration in their underlying economies, sovereign credit worthiness, or financial market conditions could negatively impact the Company's financial position.

While the Company has continued to add floating rate investments to its investment portfolio, most of its investment portfolio holdings are income-producing bonds that provide a fixed level of income. Many of the Company's investments were made at the relatively low level of interest rates prevailing over the last decade. Any increase in the market yields of the Company's holdings due to an increase in interest rates could create substantial unrealized losses in the Company's portfolio, as discussed further in a separate risk factor in this section of the Form 10-K.

The Company needs liquidity to pay its operating expenses, dividends on its common stock, interest on its debt, and liabilities. For a further description of the Company's liquidity needs, including maturing indebtedness, see the Liquidity and Capital Resources section of MD&A in this report. In the event the Company's current resources do not meet its needs, the Company may need to seek additional financing. The Company's access to additional funding will depend on a variety of factors such as market conditions, the general availability of credit to the financial services industry and its credit rating.

Should investors become concerned with any of the Company's investment holdings, including the concentration in JGBs, its access to market sources of funding could be negatively impacted. There is a possibility that lenders or debt investors may also become concerned if the Company incurs large investment losses or if the level of the Company's business activity decreases due to a market downturn or there are further adverse economic trends in the U.S. or Japan, specifically, or generally in developed markets. Similarly, the Company's access to funds may be impaired if regulatory authorities or rating agencies take negative actions. See more information on recent rating actions later in this Risk Factors section.

Broad economic factors such as consumer spending, business investment, government spending, the volatility and strength of the capital markets, and inflation all affect the business and economic environment and, indirectly, the amount and profitability of the Company's business. In an economic downturn characterized by higher unemployment, lower family income, lower corporate earnings, lower business investment and lower consumer spending, the demand for financial and insurance products could be adversely affected. This adverse effect could be particularly significant for companies such as Aflac that distribute supplemental, discretionary insurance products primarily through the worksite in the event that economic conditions result in a decrease in the number of new hires and total employees. Adverse changes in the economy could potentially lead the Company's customers to be less inclined to purchase supplemental insurance coverage or to decide to cancel or modify existing insurance coverage, which could adversely affect the Company's premium revenue, results of operations and financial condition. The Company is unable to predict the course of the global financial markets or the recurrence, duration or severity of disruptions in such markets.

Events, including those external to the Company's operations, could damage the Company's reputation.

The Company has made significant investments in the Aflac brand over a long period of time. Because insurance products are intangible, the Company's ability to compete for and maintain policyholders relies to a large extent on consumer trust in the Company's business, including its alliance partners, sales associates and other distribution partners. The perception of unfavorable business practices or financial weakness with respect to the Company, its alliance partners, sales associates or other distribution partners could create doubt regarding the Company's ability to honor the commitments it has made to its policyholders. Such a perception could also negatively impact the Company’s ability to attract and retain qualified sales associates, brokers and other distribution partners, including its alliance partners in Japan, and could have a material adverse effect on the Company's sales, results of operations and financial condition. Maintaining the Company's stature as a trustworthy

19



insurer and responsible corporate citizen, which helps support the strength of the Company's brand, is critical to the Company's reputation and the failure or perceived failure to do so could adversely affect the Company's brand value, financial condition and results of operations. For example, negative publicity or allegations of unfavorable business practices or poor governance can be rapidly and widely shared over social or traditional media or other means, and could reduce demand for the Company's insurance products, reduce the Company's ability to recruit and retain employees, or lead to greater regulatory scrutiny of the Company's operations.

Extensive regulation and changes in legislation can impact profitability and growth.

Aflac's insurance subsidiaries are subject to complex laws and regulations that are administered and enforced by a number of governmental authorities, including the FSA and Ministry of Finance (MOF) in Japan, and state insurance regulators, the SEC, the NAIC, the FIO, the U.S. Department of Justice, state attorneys general, the U.S. Commodity Futures Trading Commission, and the U.S. Treasury, including the Internal Revenue Service (IRS), in the U.S., each of which exercises a degree of interpretive latitude. In addition, proposals regarding the global regulation of insurance are under discussion, and changes to corporate form that attend the conversion of Aflac Japan to a subsidiary may introduce new forms of regulation compared to those with which the Company has historically been subject. For example, AAMJ is licensed as a discretionary asset manager under the Japan Financial Instruments and Exchange Act and is subject to rules of the Japan Investment Advisors Association, a self-regulatory organization with mandatory membership for Japan investment managers. Consequently, the Company is subject to the risk that compliance with any particular regulator's or enforcement authority's interpretation of a legal or regulatory issue may not result in compliance with another regulator's or enforcement authority's interpretation of the same issue, particularly when compliance is judged in hindsight. There is also a risk that any particular regulator's or enforcement authority's interpretation of a legal or regulatory issue may change over time to the Company's detriment. In addition, changes in the overall legal or regulatory environment may, even absent any particular regulator's or enforcement authority's interpretation of an issue changing, cause us to change the Company's views regarding the actions the Company needs to take from a legal or regulatory risk management perspective, thus necessitating changes to the Company's practices that may, in some cases, limit its ability to grow or otherwise negatively impact the profitability of the Company's business.

The primary purpose of insurance company regulatory supervision is the protection of insurance policyholders, rather than investors. The extent of regulation varies, but generally is governed by state statutes in the U.S. and by the FSA and the MOF in Japan. These systems of supervision and regulation cover, among other things:

standards of establishing and setting premium rates and the approval thereof
standards of minimum capital and reserve requirements and solvency margins, including RBC measures
restrictions on, limitations on and required approval of certain transactions between the Company's insurance subsidiaries and their affiliates, including management fee arrangements
restrictions on the nature, quality and concentration of investments
restrictions on the types of terms and conditions that the Company can include in the insurance policies offered by its primary insurance operations
limitations on the amount of dividends that insurance subsidiaries can pay
the existence and licensing status of a company under circumstances where it is not writing new or renewal business
certain required methods of accounting
reserves for unearned premiums, losses and other purposes
assignment of residual market business and potential assessments for the provision of funds necessary for the settlement of covered claims under certain policies provided by impaired, insolvent or failed insurance companies
administrative practices requirements
imposition of fines and other sanctions
Regulatory authorities periodically re-examine existing laws and regulations applicable to insurance companies and their products. Changes in these laws and regulations, or in interpretations thereof, could have a material adverse effect on the Company's financial condition and results of operations. If the Company's subsidiaries fail to meet the minimum capital or operational requirements established by its respective regulators, they could be subject to examination or corrective action, or the Company's financial strength ratings could be downgraded, or both.

Compliance with applicable laws and regulations is time consuming and personnel-intensive, and changes in these laws and regulations may materially increase the Company's direct and indirect compliance and other expenses of doing business, thus having a material adverse effect on the Company's financial condition and results of operations.

The Companyis exposed to foreign currency fluctuations in the yen/dollar exchange rate.

Due to the size of Aflac Japan, where functional currency is the Japanese yen, fluctuations in the rate of exchange between the yen and the U.S. dollar can have a significant effect on the Company's reported financial position and results of operations. Aflac Japan's premiums and approximately half of its investment income are received in yen, and its claims and most expenses are paid in yen. Aflac Japan purchases yen-denominated assets and U.S. dollar-denominated assets, which may be hedged to yen, to support yen-denominated policy liabilities. These and other yen-denominated financial statement items are, however, translated into U.S. dollars for financial reporting purposes. Accordingly, fluctuations in the yen/dollar exchange rate can have a significant effect on the Company's reported financial position and results of operations. In periods when yen weakens, translating yen into U.S. dollars causes fewer U.S. dollars to be reported. When yen strengthens, translating yen into U.S. dollars causes more U.S. dollars to be reported. Any unrealized foreign currency translation adjustments are reported in accumulated other comprehensive income. As a result, yen weakening has the effect of suppressing current year results in relation to the prior year, while yen strengthening has the effect of magnifying current year results in relation to the prior year. In addition, the weakening of the yen relative to the U.S. dollar will generally adversely affect the value of the Company's yen-denominated investments in U.S. dollar terms.

The Company engages in certain foreign currency hedging activities for the purpose of hedging the yen exposure to its net investment in operations in Japan. These hedging activities are limited in scope, and the Company cannot provide assurance that these activities will be effective.

Unhedged U.S. dollar-denominated securities held by Aflac Japan are exposed to foreign exchange fluctuations, which impact SMR. In periods of yen strengthening, the unhedged U.S. dollar-denominated investments will experience unrealized foreign exchange losses, negatively impacting SMR. This impact increases when the size of the unhedged U.S. dollar-denominated portfolio increases, which can occur due to the purchase of additional unhedged U.S. dollar-denominated investments, or through termination or expiration of existing hedges. Unrealized currency gains and losses on unhedged U.S. dollar-denominated securities are monetized (or, in other words, are economically realized) only upon converting the proceeds from the sale, maturity or redemption of these securities to yen, which primarily occurs when yen are needed to satisfy policyholder obligations or other business expenses of Aflac Japan. To mitigate exposure to the foreign exchange risk from U.S. dollar-denominated investments and to reduce SMR volatility, the Company engages in certain currency hedging activities. However, these hedging activities are limited in scope and the Company cannot provide assurance that its hedging strategies will be effective. As a result, periods of unusually volatile currency exchange rates could result in limitations on dividends available to the Parent Company.

As indicated in the MD&A, the Company has determined that the unhedged U.S. dollar-denominated investment portfolio acts as a natural economic currency hedge of a portion of the Company’s investment in Aflac Japan against erosion of economic value. However, the unhedged U.S. dollar-denominated investment portfolio at the same time creates an unmatched foreign currency exposure and subjects Aflac Japan to volatility in regulatory capital and earnings, which may adversely impact Aflac Japan’s ability to pay dividends to the Parent Company. The overall investment strategy in Aflac Japan is guided primarily by the objective of securing the long-term financial strength of Aflac Japan and funding of yen liabilities. As a result, the Company has historically maintained and currently maintains the size of the unhedged portfolio at levels below the economic equity surplus in Aflac Japan. However, there can be no assurance that this strategy will be successful.

Furthermore, for regulatory accounting purposes, there are certain requirements for realizing impairments that could be triggered by changes in the rate of exchange between the yen and U.S. dollar and could negatively impact Aflac Japan's earnings and the corresponding dividends and capital deployment.

Additionally, the Company is exposed to currency risk when yen cash flows are converted into U.S. dollars, resulting in an increase or decrease in the Company's U.S. dollar-denominated cash flows and earnings when exchange gains or losses, respectively, are realized. This primarily occurs when the Company dividends funds from Aflac Japan to the Parent Company, but it also has an impact when cash in the form of yen is converted to U.S. dollars for investment into U.S. dollar-denominated assets. The exchange rates prevailing at the time of dividend payment may differ from the exchange rates prevailing at the time the yen profits were earned. In 2018, the Parent Company began entering into forward contracts to accomplish a dual objective of hedging foreign currency exchange rate risk related to dividend payments by Aflac Japan, and reducing enterprise-wide hedge costs. If the markets experience a significant strengthening of yen, this could cause cash strain at the Parent Company as a result of cash collateral and potentially cash settlement requirements. Based on the timing and severity of exchange rate fluctuations combined with the level of outstanding activity in this program, the cash strain at the Parent Company could be significant. 

For more information regarding unhedged U.S. dollar-denominated securities, see the risk factor below entitled, “Lack of availability of acceptable yen-denominated investments could adversely affect the Company’s results of operations, financial

21



position or liquidity”. For more information regarding foreign currency risk, see the Currency Risk subsection within the Market Risks of Financial Instruments section of MD&A.

Tax rates applicable to the Company may change.

The Company is subject to taxation in Japan, and in the U.S. under federal and numerous state and local tax jurisdictions. In preparing the Company's financial statements, the Company estimates the amount of tax that will become payable, but the Company's effective tax rate may be different than estimates due to numerous factors including accounting for income taxes, the mix of earnings from Japan and the U.S., the results of tax audits, adjustments to the value of uncertain tax positions, changes to estimates and other factors. Further, changes in U.S. or Japan tax laws or interpretations of such laws could increase the Company's corporate taxes and reduce earnings.

In addition, it remains difficult to predict the timing and effect that future tax law changes could have on the Company's earnings both in the U.S. and in foreign jurisdictions. Any of these factors could cause the Company to experience an effective tax rate significantly different from previous periods or the Company's current estimates. If the Company's effective tax rate were to increase, the Company's financial condition and results of operations could be adversely affected.

A decline in the creditworthiness of other financial institutions could adversely affect the Company.

The Company has exposure to and routinely executes transactions with counterparties in the financial services industry, including broker dealers, derivative counterparties, commercial banks and other institutions.

The Company uses derivative instruments to mitigate various risks associated with its investment portfolio, notes payable, and subsidiary dividends. The Company enters into a variety of agreements involving assorted instruments including foreign currency forward contracts; foreign currency options; foreign currency swaps; and interest rate swaps and swaptions. The Company's use of derivatives results in financial exposure to derivative counterparties. If the Company's counterparties fail or refuse to honor their obligations under derivative instruments, the Company's hedges of the risks will be ineffective, and the Company's financial condition and results of operations could be adversely affected.

The Company engages in derivative transactions directly with unaffiliated third parties under International Swaps and Derivatives Association, Inc. (ISDA) agreements and other documentation. Most of the ISDA agreements also include Credit Support Annexes (CSAs) provisions, which generally provide for two-way collateral postings at the first dollar of exposure. The Company mitigates the risk that counterparties to transactions might be unable to fulfill their contractual obligations by monitoring counterparty credit exposure and collateral value while generally requiring that collateral be posted at the outset of the transaction. In addition, a significant portion of the derivative transactions have provisions that give the counterparty the right to terminate the transaction upon a downgrade of Aflac’s financial strength rating. The actual amount of payments that the Company could be required to make, depends on market conditions, the fair value of outstanding affected transactions, and other factors prevailing at and after the time of the downgrade. If the Company is required to post collateral to support derivative contracts and/or pay cash to settle the contracts at maturity, the Company's liquidity could be strained. In addition, the Company's cleared swaps result in counterparty exposure to clearing brokers and central clearinghouses; while this exposure is mitigated in part by clearinghouse and clearing broker capital and regulation, no assurance can be provided that these counterparties will fulfill their obligations. The Company also has exposure to counterparties to securities lending transactions in the event they fail to return loaned securities. The Company is also exposed to the risk that there may be a decline in value of securities posted as collateral for securities lending programs or a decline in value of investments made with cash posted as collateral for such programs.

Further, the Company has agreements with various financial institutions for the distribution of its insurance products. For example, at December 31, 2019, the Company had agreements with 367 banks to market Aflac's products in Japan. Sales through these banks represented 4.3% of Aflac Japan's new annualized premium sales in 2019. Any material adverse effect on these or other financial institutions could also have an adverse effect on the Company's sales.
The Company has entered into significant reinsurance transactions with large, highly rated counterparties. Negative events or developments affecting any one of these counterparties could have an adverse effect on the Company's financial position or results of operations.
All of these risks related to exposure to other financial institutions could adversely impact the Company's consolidated results of operations and financial condition.


22



The determination of the amount of impairments taken on the Company's investments is based on significant valuation judgments and could materially impact its results of operations or financial position.
An investment in a fixed maturity security is impaired if the fair value falls below book value. The Company regularly reviews its entire investment portfolio for declines in value. The majority of the Company's investments are evaluated for other-than-temporary impairment using the Company's debt impairment model.
The Company's debt impairment model includes emphasis on the ultimate collection of the cash flows from its investments. The determination of the amount of impairments under this model is based upon the Company's periodic evaluation and assessment of known and inherent risks associated with the respective securities. Such evaluations and assessments are revised as conditions change and new information becomes available.
For the Company's fixed maturity securities reported in the available-for-sale portfolio, the Company reports the investments at fair value in the statement of financial condition and records any unrealized gain or loss in the value of the asset in accumulated other comprehensive income. For the Company's held-to-maturity securities portfolio, the Company reports the investments at amortized cost. Under the debt impairment model, the determination of whether an impairment in value is other than temporary is based largely on the Company's evaluation of the issuer's creditworthiness. The Company must apply considerable judgment in determining the likelihood of the security recovering in value while the Company owns it. Factors that may influence this include the Company's assessment of the issuer’s ability to continue making timely payments of interest and principal, the overall level of interest rates and credit spreads, and other factors. The Company also verifies whether it has the intent to sell or if it is more likely than not the Company would be required to sell the security prior to recovery of its amortized cost. If the Company determines it is unlikely to recover the book value of the instrument prior to disposal of the security, the Company will reduce the carrying value of the security to its fair value and recognize any associated impairment loss in the Company's consolidated statement of earnings or other comprehensive income, depending on the nature of the loss.
For regulatory accounting purposes for Aflac Japan, there are certain requirements for realizing impairments that could be triggered by rising interest rates, credit-related losses, or changes in foreign exchange, negatively impacting Aflac Japan's earnings and corresponding dividend and capital deployment.
The Company's management updates its evaluations regularly as conditions change and as new information becomes available and reflects impairment losses in the Company's income statement when considered necessary. Furthermore, additional impairments may need to be taken in the future. Historical trends may not be indicative of future impairments.

U.S. tax audit risk related to conversion of the Japan branch to a subsidiary could adversely impact the Company's financial position.

The conversion of the Japan branch to a legal subsidiary, which the Company executed in the second quarter of 2018, was a complex, tax-free transaction that is conditioned on the continued validity of a private letter ruling the Company received from the IRS. Notwithstanding the receipt of the private letter ruling, the IRS could determine that the Japan branch conversion should be treated as a taxable transaction. For example, the IRS could conclude that the representations, assumptions and covenants on which the private letter ruling is based are untrue, not accurate, or have not been fulfilled. If the IRS made such a conclusion, the Company could incur significant U.S. federal income tax liabilities or litigation costs to defend the tax-free treatment of the transaction outlined by the private letter ruling. Such liabilities or costs could have a material adverse effect on the Company's business, results of operations and financial condition.

As a holding company, the Parent Company depends on the ability of its subsidiaries to transfer funds to it to meet its debt service and other obligations and to pay dividends on its common stock.
The Parent Company is a holding company and has no direct operations, and its most significant assets are the stock of its subsidiaries. Because the Parent Company conducts its operations through its operating subsidiaries, the Parent Company depends on those entities for dividends and other payments to generate the funds necessary to meet its debt service and other obligations, to pay dividends on and conduct repurchases of its common stock, and to make investments into its subsidiaries or external investment opportunities.
Aflac is domiciled in Nebraska and is subject to insurance regulations that impose certain limitations and restrictions on payments of dividends, management fees, loans and advances by Aflac to the Parent Company. The Nebraska insurance statutes require prior approval for dividend distributions that exceed the greater of the net income from operations, which excludes net realized investment gains, for the previous year determined under statutory accounting principles, or 10% of statutory capital and surplus as of the previous year-end. In addition, the Nebraska insurance department must approve

23



service arrangements and other transactions within the affiliated group of companies. After the Japan branch conversion, the Nebraska insurance department and the FSA approved their respective domiciled insurance company service arrangements and transactions. The FSA does not allow dividends or other payments from Aflac Japan unless it meets certain financial criteria as governed by Japanese corporate law. Under these criteria, dividend capacity at the Japan subsidiary will be defined as retained earnings plus other capital reserve less net after-tax net unrealized losses on available-for-sale securities.
The ability of Aflac and Aflac Japan to pay dividends or make other payments to the Parent Company could also be constrained by the Company's dependency on financial strength ratings from independent rating agencies. The Company's ratings from these agencies depend to a large extent on Aflac's capitalization level. Any inability of Aflac to pay dividends or make other payments to the Parent Company could have a material adverse effect on the Company's financial condition and results of operations.
For the foregoing reasons, there is no assurance that the earnings from, or other available assets of, the Parent Company's operating subsidiaries will be sufficient to make distributions to enable the Company to operate.
Any decrease in the Company's financial strength or debt ratings may have an adverse effect on its competitive position and access to liquidity and capital.

Financial strength ratings can play an important role in establishing the competitive position of insurance companies. On an ongoing basis, NRSROs review the financial performance and condition of many insurers, including the Company and its competitors. They may assign multiple ratings including a financial strength rating, reflecting their view of the insurer’s ability to pay claims on a timely basis, and ratings on an insurer’s senior and subordinated debt obligations, indicating their view of an insurer’s ability to make timely payments on their debt obligations.

NRSROs may change their ratings or outlook on an insurer's ratings due to a variety of factors including the NRSRO’s assessment of the insurer’s strength of operations and overall financial condition. Some factors that may influence ratings include competitive position; profitability; cash generation and other sources of liquidity; capital levels; quality of the investment portfolio; and perception of management capabilities. The ratings assigned to the Company by the NRSROs are important factors in the Company's ability to access liquidity and capital from the bank market, debt capital markets or other available sources, such as reinsurance transactions. Downgrades to the Company's credit ratings could give its derivative counterparties the right to require early termination of derivatives transactions or delivery of additional collateral, thereby adversely affecting the Company's liquidity.

In view of the difficulties experienced after the financial crisis by many financial institutions, including those in the insurance industry, the NRSROs have heightened the level of scrutiny that they apply to such institutions. Steps taken by the NRSROs include an increase in the frequency and scope of their reviews, additional information requests from the companies that they rate, including additional information regarding the valuation of investment securities held, and, in certain cases, an increase in the capital and other requirements employed in their models for maintenance of certain rating levels.

On September 16, 2015, S&P downgraded their credit rating of Japan’s sovereign debt. Following this action, they also downgraded several other foreign insurers, including the Company. The Company's significant operations in Japan and corresponding regulation by the Japanese FSA, combined with its significant exposure to JGBs as outlined above, resulted in S&P downgrading the financial strength rating of Aflac's core insurance operations to A+ and the Parent Company's senior debt rating to A-, both with a stable outlook. While S&P made no further downgrades to the Company's ratings between 2016 and 2019, they state that a downgrade of Japan's sovereign rating could lead to a downgrade of the Company's financial strength rating. As a matter of policy, S&P rarely rates insurance companies above the sovereign long-term rating of the country of domicile because during times of stress, the sovereign’s regulatory and supervisory powers may restrict an insurer’s or financial system’s flexibility. Moody’s has also stated that the following factors could lead to a downgrade of the Company’s ratings: a downgrade of the U.S. or Japanese operating entities; or a downgrade of the Government of Japan sovereign debt rating.

In addition to the impact on the Company's access to liquidity, as mentioned above, a downgrade of the Company's ratings could have a material adverse effect on agent recruiting and retention, sales, competitiveness and the marketability of its products which could negatively impact the Company's liquidity, operating results and financial condition. Additionally, sales through the bank channel in Japan could be adversely affected as a result of their reliance and sensitivity to ratings levels.

The Company cannot predict what actions rating agencies may take, or what actions the Company may take in response to the actions of rating agencies, which could adversely affect the Company's business. As with other companies in the financial services industry, the Company's ratings could be downgraded at any time and without any notice by any NRSRO.

The Company's risk management policies and procedures may prove to be ineffective and leave the Company exposed to unidentified or unanticipated risk, which could adversely affect the Company's businesses or result in losses.

The Company has developed an enterprise-wide risk management and governance framework to mitigate risk and loss to the Company. The Company maintains policies, procedures and controls intended to identify, measure, monitor, report and analyze the risks to which the Company is exposed.
However, there are inherent limitations to risk management strategies because risk may exist, or emerge in the future, that the Company has not appropriately anticipated or identified. If the Company's risk management framework proves ineffective, the Company may suffer unexpected losses and could be materially adversely affected. As the Company's businesses change and the markets in which it operates evolve, the Company's risk management framework may not evolve at the same pace as those changes. As a result, there is a risk that new products or new business strategies may present risks that are not appropriately identified, monitored or managed. In times of market stress, unanticipated market movements or unanticipated claims experience resulting from greater than expected morbidity, mortality, longevity, or persistency, the effectiveness of the Company's risk management strategies may be limited, resulting in losses to the Company. In addition, under difficult or less liquid market conditions, the Company's risk management strategies may not be effective because other market participants may be using the same or similar strategies to manage risk under the same challenging market conditions. In such circumstances, it may be difficult or more expensive for the Company to mitigate risk due to the activity of such other market participants.
Many of the Company's risk management strategies or techniques are based upon historical customer and market behavior and all such strategies and techniques are based to some degree on management’s subjective judgment. The Company cannot provide assurance that its risk management framework, including the underlying assumptions or strategies, will be accurate and effective.
Management of operational, legal and regulatory risks requires, among other things, policies, procedures and controls to record properly and verify a large number of transactions and events, and these policies, procedures and controls may not be fully effective. Models are utilized by the Company's businesses and corporate areas primarily to project future cash flows associated with pricing products, calculating reserves and valuing assets, as well as in evaluating risk and determining capital requirements, among other uses. These models are utilized under a risk management policy approved by the Company's executive risk management committees, however, the models may not operate properly and rely on assumptions and projections that are inherently uncertain. As the Company's businesses continue to grow and evolve, the number and complexity of models the Company utilizes expands, increasing the Company's exposure to error in the design, implementation or use of models, including the associated input data and assumptions.
Past or future misconduct by the Company's employees or employees of the Company's third parties (suppliers which are cost-based relationships and alliance partners which are revenue-generating relationships) could result in violations of law by the Company, regulatory sanctions and/or serious reputational or financial harm and the precautions the Company takes to prevent and detect this activity may not be effective in all cases. Despite the Company's published Supplier Code of Conduct, due diligence of the Company's alliance partners, and rigorous contracting procedures (including financial, legal, IT security, and risk reviews), there can be no assurance that controls and procedures that the Company employs, which are designed to assess third party viability and prevent the Company from taking excessive or inappropriate risks, will be effective. Additionally, the use of third parties also poses operational risks that could result in financial loss, operational disruption, brand damage, or compliance issues. Inadequate oversight of Aflac’s third party suppliers due to the lack of policies, procedures, training and governance may lead to financial loss or damage to the Aflac brand.
The concentration of the Company's investment portfolios in any particular single-issuer or sector of the economy may have an adverse effect on the Company's financial position or results of operations.
Negative events or developments affecting any particular single issuer, industry, group of related industries, asset class or geographic sector may have an adverse impact on a particular holding or set of holdings, which may increase risk of loss from defaults due to non-payment of interest or principal. The Company seeks to minimize this risk by maintaining an appropriate level of diversification. To the extent the Company has concentrated positions, it could have an adverse effect on the Company's results of operations and financial position. The Company's global investment guidelines establish

25



concentration limits for its investment portfolios.

For details on the concentrations within the Company's investment portfolios, see the Investments section of Item 7, MD&A, and the Credit Risk section of Item 7A, Quantitative and Qualitative Disclosures about Market Risk, of this Form 10-K.

The valuation of the Company's investments and derivatives includes methodologies, estimations and assumptions which are subject to differing interpretations and could result in changes to investment valuations that may adversely affect the Company's results of operations or financial condition.
The Company reports a significant amount of its fixed maturity securities and other financial instruments at fair value. As such, valuations may include inputs and assumptions that are less observable or require greater estimation as well as valuation methods which are more sophisticated, thereby resulting in values which may be greater or less than the value at which the investments may be ultimately sold. Rapidly changing and unprecedented credit and equity market conditions could materially impact the valuation of securities as reported within the Company's consolidated financial statements and the period-to-period changes in value could vary significantly.

Valuations of the Company's derivatives fluctuate with changes in underlying market variables, such as interest rates and foreign currency exchange rates. During periods of market turbulence created by political instability, economic uncertainty, government interventions or other factors, the Company may experience significant changes in the volatility of its derivative valuations. Extreme market conditions can also affect the liquidity of such instruments creating marked differences in transaction levels and counterparty valuations. Depending on the severity and direction of the movements in its derivative valuations, the Company will face increases in the amount of collateral required to be posted with its counterparties. Liquidity stresses to the Company may also occur if the required collateral amounts increase significantly over a very short period of time. Conversely, the Company may be exposed to an increase in counterparty credit risk for short periods of time while calling collateral from its counterparties.

Elimination of LIBOR as an interest rate benchmark may create uncertainty in valuation of loans, derivatives and other assets where valuation and interest rates are based on LIBOR, and may create uncertainty in the pricing of such assets in markets for their sale and disposition.

For further discussion on investment and derivative valuations, see the Critical Accounting Estimates section in Item 7, Management's Discussion and Analysis, and Notes 1, 3, 4, and 5 of the Notes to the Consolidated Financial Statements in this Form 10-K.

The Company depends heavily on key management personnel, and the loss of services of one or more of its key executives could harm the Company's business.

The Company’s success depends to a significant extent upon the efforts and abilities of its key management personnel. The loss of the services of one or more of the Company's senior executives could significantly undermine its management expertise and the Company's business could be adversely affected.

Changes in accounting standards issued by the Financial Accounting Standard Boards (FASB) or other standard-setting bodies may adversely affect the Company's financial statements.
The Company's financial statements are subject to the application of U.S. GAAP, which is periodically revised and/or expanded. Accordingly, from time to time the Company is required to adopt new or revised accounting standards issued by recognized authoritative bodies, including the FASB. The impact of accounting pronouncements that have been issued but not yet implemented and are applicable to the Company is disclosed in Note 1 of the Notes to the Consolidated Financial Statements. The pronouncements expected to have the most significant impact on the Company's financial position or results of operations are outlined below.
In June 2016, the FASB issued Accounting Standard Update (ASU) 2016-13, Financial Instruments - Credit Losses: Measurement of Credit Losses on Financial Instruments. The amendments in this update require a financial asset (or a group of financial assets) measured on an amortized cost basis to be presented net of an allowance for current expected credit losses in order to reflect the amount expected to be collected on the financial asset(s). The Company currently estimates the after-tax net impact from the adoption of ASU 2016-13 at a $56 million decrease to retained earnings, which primarily relates to loans and loan receivables. The amendments are effective for fiscal years beginning after December 15, 2019.

26



Additionally, in August 2018 the FASB issued ASU 2018-12, Financial Services - Insurance, Targeted Improvements to the Accounting for Long-Duration Contracts. The amendments in this update will significantly change how insurers account for long-duration contracts. Among the issues addressed in the amendments is the requirement to review and, if there is a change, update cash flow assumptions for the liability for future policy benefits at least annually, and to update the discount rate assumption quarterly. The Company anticipates that the requirement to review and update assumptions for liability for future policy benefits will have a significant impact on its results of operations, systems, processes, and controls, while the requirement to update the discount rate will have a significant impact on the other comprehensive income component of its equity. The amendments are effective for fiscal years beginning after December 15, 2021. See Critical Accounting Estimates section of Item 7. MD&A in this report.

Changes to accounting standards could have a material adverse effect on the Company's results of operations and financial condition. For information on new accounting pronouncements and the impact, if any, on the Company's financial position or results of operations, see Note 1 of the Notes to the Consolidated Financial Statements in this report.
The Company faces risks related to litigation, regulatory investigations and inquiry and other matters.

The Company is a defendant in various lawsuits considered to be in the normal course of business. The final results of any litigation cannot be predicted with certainty, and plaintiffs may seek very large amounts in class actions or other litigation. Although some of this litigation is pending in states where large punitive damages, bearing little relation to the actual damages sustained by plaintiffs, have been awarded in recent years, the Company believes the outcome of pending litigation will not have a material adverse effect on its financial position, results of operations, or cash flows. However, a substantial legal liability or a significant federal, state or other regulatory action against the Company, as well as regulatory inquiries or investigations, could harm the Company's reputation, result in changes in operations, result in material fines or penalties, result in significant costs due to legal fees, settlements or judgments against the Company, or otherwise have a material adverse effect on the Company's business, financial condition and results of operations. Without limiting the foregoing, the litigation and regulatory matters the Company is, has been, or may become, subject to include matters related to sales agent recruiting, policy sales practices, claim payments and procedures including denial or delay of benefits, material misstatements or omissions in the Company's financial reports or other public statements, and/or corporate governance, corporate culture or business ethics matters. Further, the Company may be subject to claims of or litigation regarding sexual or other forms of misconduct or harassment, or discrimination on the basis of race, color, national origin, religion, gender, or other bases, notwithstanding that the Company's Code of Business Conduct and Ethics prohibits such harassment and discrimination by its employees, the Company has ongoing training programs and provide opportunities to report claims of noncompliant conduct, and it investigates and may take disciplinary action regarding alleged harassment or discrimination. Any violations of or deviation from laws, regulations, internal or external codes or standards of normative behavior, or perceptions of such violations or deviations, by the Company's employees or by independent sales agents could adversely impact the Company's reputation and brand value, financial condition and results of operations.

Allegations or determinations of agent misclassification could adversely affect the Company’s results of operations, financial condition and liquidity.

A majority of the Company's U.S. sales force is, and has historically been, comprised of independent agents. While the Company believes that it has properly classified such agents as independent contractors, the Company may be subject to claims, regulatory action by state or federal departments of labor or tax authorities or litigation asserting that such agents are employees. The laws and regulations governing the classification of workers in the U.S. may be changed or interpreted differently compared to past interpretations, including in states where the Company generates significant sales through independent agents. An allegation or determination that independent agents in the Company’s U.S. sales force have been misclassified as independent contractors could result in changes in the Company’s operations and U.S. business model, result in material fines or penalties, result in significant costs due to legal fees, settlements or judgments against the Company, or otherwise have a material adverse effect on the Company's business, results of operation, financial condition and liquidity.

ITEM 3. LEGAL PROCEEDINGS

The Company is a defendant in various lawsuits considered to be in the normal course of business.

EXECUTIVE SUMMARY

For the full year of 2019, total revenues were up 2.5% to $22.3 billion, compared with $21.8 billion for the full year of 2018. Net earnings were $3.3 billion, or $4.43 per diluted share, compared with $2.9 billion, or $3.77 per diluted share, for the full year of 2018.

Results for 2019 included pretax net realized investment losses of $135 million, compared with net realized investment losses of $430 million in 2018. Net investment losses in 2019 included $31 million of other-than-temporary impairment losses and changes in loan loss reserves; $236 million in net losses from certain derivatives and foreign currency gains or losses; $101 million of net gains on equity securities; and $31 million of net gains from sales and redemptions.

Adjusted earnings(2) for the full year of 2019 were $3.3 billion, or $4.44 per diluted share, compared with $3.2 billion, or $4.16 per diluted share, in 2018. The stronger yen/dollar exchange rate impacted adjusted earnings per diluted share by $.02.

Total investments and cash at the end of December 2019 were $138.1 billion, compared with $126.2 billion at December 31, 2018. In 2019, Aflac Incorporated repurchased $1.6 billion, or 32.0 million of its common shares. At the end of December, the Company had 37.1 million remaining shares authorized for repurchase.

Shareholders’ equity was $29.0 billion, or $39.84 per share, at December 31, 2019, compared with $23.5 billion, or $31.06 per share, at December 31, 2018. Shareholders’ equity at December 31, 2019 included a net unrealized gain on investment securities and derivatives of $8.5 billion, compared with a net unrealized gain of $4.2 billion at December 31, 2018. Shareholders’ equity at December 31, 2019 also included an unrealized foreign currency translation lossof $1.6 billion, compared with an unrealized foreign currency translation loss of $1.8 billion at December 31, 2018. The annualized return on average shareholders’ equity in 2019 was 12.6%.

The annualized adjusted return on equity excluding foreign currencyimpact(2) in 2019 was 15.1%.

INDUSTRY TRENDS

The Company is impacted by financial markets, economic conditions, regulatory oversight and a variety of trends that affect the industries where it competes.

Financial and Economic Environment

The Company’s business and results of operations are materially affected by conditions in the global capital markets and the economy generally. Stressed conditions, volatility and disruptions in global capital markets, particular markets, or financial asset classes can have an adverse effect on the Company, in part because the Company has a large investment portfolio and its insurance liabilities and derivatives are sensitive to changing market factors. See Item 1A. Risk Factors for the risk factor entitled, "Difficult conditions in global capital markets and the economy could have a material adverse effect on the Company's investments, capital position, revenue, profitability, and liquidity and harm the Company's business."

Demographics

Japan Business - With Japan’s aging population and the rise in healthcare costs, supplemental health care insurance products remain attractive. However, due to the aging population and decline in birthrate, new opportunities for customer demographics are not as readily available. Japan’s existing customers and potential customers seek products that are easily understood, cost-effective and can be accessed through technology-enabled devices.

(2) See the Results of Operations section of this MD&A for a definition of this non-U.S. GAAP financial measure.

35



U.S. Business - Customer demographics continue to evolve and new opportunities present themselves in different customer segments such as the millennial and multicultural markets. Customer expectations and preferences are changing. Trends indicate existing customers and potential customers seek cost-effective solutions that are easily understood and can be accessed through technology-enabled devices.

2020 OUTLOOK

The Company’s strategy to drive long-term shareholder value is to pursue growth through product development, distribution expansion and digital advancements to improve the customer experience.

The Company's objectives in 2020 are to maintain strong pre-tax margins in its Aflac Japan and Aflac U.S. segments through disciplined product pricing, stable investment returns and leveraging a period of favorable benefit ratios to invest in its platform for future growth and efficiency. The Company believes that its market-leading position, powerful brand recognition and diverse distribution in Japan and the U.S. will provide support toward these objectives.

The Company believes that its efforts will support its prudent strategies for capital deployment in the form of dividends, share repurchases, and opportunistic investments that enhance the Company’s business with a focus on digital distribution and leveraging the Company’s brand, distribution and scale. The Company has stated that the dividend payout ratio from its Aflac Japan segment is likely to be to 100% of FSA earnings from Aflac Japan and 100% of U.S. statutory earnings from Aflac U.S. In its Aflac U.S. segment, the Company plans to maintain a risk-based capital (RBC) ratio in the 500% range for 2020.

Aflac Japan Segment
In Japan, the Company anticipates that the shift in earned premium from first sector savings products to third sector cancer and medical products and first sector protection products, will continue to result in moderately lower benefit ratios in the Aflac Japan segment. The Company also expects this shift in business mix, plus continued investment in IT and digital advancements, to result in moderately higher expense ratios for Aflac Japan. The Company anticipates the Japan segment will face revenue challenges in 2020 due to the run-off and paid-up status of first sector savings and third sector products. The Company expects a decline in the range of .7% in third sector and first sector protection earned premium for 2020. In addition, net investment income is expected to decline modestly as compared to 2019, due in part to the low interest rate environment in Japan and de-risking of the portfolio, partially offset by lower hedge cost as a result of a reduction in the hedge ratio in the fourth quarter of 2019.

Aflac U.S. Segment
The Company expects the profit margins for the Aflac U.S. segment to remain strong, providing a prudent opportunity to reinvest profits back into the U.S. business. The Company anticipates that in 2020, benefit ratios in the U.S. will remain stable and that expense ratios will continue to be elevated in light of investments into U.S. platforms in both the individual and group channels. The Company expects Aflac U.S. to generate earned premium growth in the range of 1% in 2020. Net investment income is expected to decline modestly, primarily as the result of the Company’s implemented U.S. capital and RBC draw-down plan.

Corporate and Other Segment
The Company expects corporate segment results to benefit from net investment income driven by increased capital and liquidity held at the Parent Company, as well as the increase in size of the Company’s enterprise currency hedging strategy. The anticipated increase in investment income is expected to be partially offset by increased costs associated with continued investment in Aflac Corporate Ventures initiatives.

RESULTS OF OPERATIONS

The Company earns its revenues principally from insurance premiums and investments. The Company’s operating expenses primarily consist of insurance benefits provided and reserves established for anticipated future insurance benefits, general business expenses, commissions and other costs of selling and servicing its products. Profitability for the Company depends principally on its ability to price its insurance products at a level that enables the Company to earn a margin over the costs associated with providing benefits and administering those products. Profitability also depends on, among other items, actuarial and policyholder behavior experience on insurance products, and the Company's ability to attract and retain customer assets, generate and maintain favorable investment results, effectively deploy capital and utilize tax capacity, and manage expenses.

Yen–denominated income statement accounts are translated to U.S. dollars using a weighted average Japanese yen/U.S. dollar foreign exchange rate, except realized gains and losses on security transactions which are translated at the exchange rate on the trade date of each transaction. Yen–denominated balance sheet accounts are translated to U.S. dollars using a spot Japanese yen/U.S. dollar foreign exchange rate.

The following discussion includes references to the Company's performance measures, adjusted earnings, adjusted earnings per diluted share, and amortized hedge costs/income, which are not calculated in accordance with U.S. GAAP (non-U.S. GAAP). These measures exclude items that the Company believes may obscure the underlying fundamentals and trends in the Company's insurance operations because they tend to be driven by general economic conditions and events or related to infrequent activities not directly associated with its insurance operations. The Company's management uses adjusted earnings and adjusted earnings per diluted share to evaluate the financial performance of its insurance operations on a consolidated basis, and the Company believes that a presentation of these measures is vitally important to an understanding of its underlying profitability drivers and trends of its insurance business. The Company believes that amortized hedge costs/income, which are a component of adjusted earnings, measure the periodic currency risk management costs/income related to hedging certain foreign currency exchange risks and are an important component of net investment income.

The Company defines the non-U.S. GAAP financial measures included in this filing as follows:

Adjusted earnings are the profits derived from operations.The most comparable U.S. GAAP measure is net earnings. Adjusted earnings are adjusted revenues less benefits and adjusted expenses. The adjustments to both revenues and expenses account for certain items that cannot be predicted or that are outside management’s control. Adjusted revenues are U.S. GAAP total revenues excluding realized investment gains and losses, except for amortized hedge costs/income related to foreign currency exposure management strategies and net interest cash flows from derivatives associated with certain investment strategies. Adjusted expenses are U.S. GAAP total acquisition and operating expenses including the impact of interest cash flows from derivatives associated with notes payable but excluding any nonrecurring or other items not associated with the normal course of the Company’s insurance operations and that do not reflect the Company's underlying business performance.

Adjusted earnings per share (basic or diluted) are adjusted earnings for the period divided by the weighted average outstanding shares (basic or diluted) for the period presented. The most comparable U.S. GAAP measure is net earnings per share.

Amortized hedge costs/income represent costs/income incurred or recognized in using foreign currency forward
contracts to hedge certain foreign exchange risks in the Company's Japan segment (costs) or in the Corporate and Other segment (income). These amortized hedge costs/income are derived from the difference between the foreign currency spot rate at time of trade inception and the contractual foreign currency forward rate, recognized on a straight line basis over the term of the hedge. There is no comparable U.S. GAAP financial measure for amortized hedge costs/income.

Adjusted earnings and adjusted earnings per diluted share excluding current period foreign currency impact are computed using the average yen/dollar exchange rate for the comparable prior year period, which eliminates fluctuations driven solely by yen-to-dollar currency rate changes.


37



Amounts excluding foreign currency impact on U.S. dollar-denominated investment income were determined using the average dollar/yen exchange rate for the comparable prior year period.

Adjusted book value is the U.S. GAAP book value (representing total shareholders' equity), less AOCI as recorded on the U.S. GAAP balance sheet. The Company considers adjusted book value important as it excludes AOCI, which fluctuates due to market movements that are outside management's control.

Adjusted return on equity (ROE) excluding foreign currency impact is calculated using adjusted earnings excluding the impact of the yen/dollar exchange rate, as reconciled with total U.S. GAAP net earnings, divided by average shareholders’ equity, excluding AOCI. The most comparable U.S. GAAP financial measure is return on average equity as determined using net earnings and average total shareholders’ equity.

The following table is a reconciliation of items impacting adjusted earnings and adjusted earnings per diluted share to the most directly comparable U.S. GAAP measures of net earnings and net earnings per diluted share, respectively, for the years ended December 31.

Reconciling Items

Realized Investment Gains and Losses

The Company's investment strategy is to invest primarily in fixed maturity securities to provide a reliable stream of investment income, which is one of the drivers of the Company’s growth and profitability. This investment strategy incorporates asset-liability matching (ALM) to align the expected cash flows of the portfolio to the needs of the Company's liability structure. The Company does not purchase securities with the intent of generating capital gains or losses. However, investment gains and losses may be realized as a result of changes in the financial markets and the creditworthiness of specific issuers, tax planning strategies, and/or general portfolio management and rebalancing. The realization of investment gains and losses is independent of the underwriting and administration of the Company's insurance products. Realized investment gains and

38



losses include securities transactions, impairments, changes in loan loss reserves, derivative and foreign currency activities and changes in fair value of equity securities.
Securities Transactions, Impairments, and Gains (Losses) on Equity Securities

Securities transactions include gains and losses from sales and redemptions of investments where the amount received is different from the amortized cost of the investment. Impairments include other-than-temporary-impairment losses on investment securities as well as changes in loan loss reserves for loan receivables. Starting in the first quarter of 2018, gains and losses from changes in fair value of equity securities are recorded in earnings.
Certain Derivative and Foreign Currency Gains (Losses)

The Company's derivative activities include foreign currency forwards and options on certain fixed maturity securities; foreign currency forwards and options that economically hedge certain portions of forecasted cash flows denominated in yen and hedge the Company's long-term exposure to a weakening yen; foreign currency swaps associated with certain senior notes and subordinated debentures; foreign currency swaps and credit defaults swaps held in consolidated variable interest entities (VIEs); interest rate swaps used to economically hedge interest rate fluctuations in certain variable-rate investments; and interest rate swaptions to hedge changes in the fair value associated with interest rate changes for certain dollar-denominated available-for-sale securities. Gains and losses are recognized as a result of valuing these derivatives, net of the effects of hedge accounting. The Company also excludes the accounting impacts of remeasurement associated with changes in the yen/dollar exchange rate from adjusted earnings. Amortized hedge costs/ income related to certain foreign currency exposure management strategies (see Amortized Hedge Cost/Income section below), and net interest cash flows from derivatives associated with certain investment strategies and notes payable are reclassified from realized investment gains (losses) and included in adjusted earnings.

Amortized hedge costs/income can fluctuate based upon many factors, including the derivative notional amount, the length of time of the derivative contract, changes in both U.S. and Japan interest rates, and supply and demand for dollar funding. Amortized hedge costs and income have fluctuated in recent periods due to changes in the previously mentioned factors. For additional information regarding foreign currency hedging, refer to Hedging Activities in the Investments section of this MD&A.

For additional information regarding realized investment gains and losses, including details of reported amounts for the periods presented, see Notes 3 and 4 of the Notes to the Consolidated Financial Statements.

Other and Non-recurring Items

The U.S. insurance industry has a policyholder protection system that provides funds for the policyholders of insolvent insurers. The system can result in periodic charges to the Company as a result of insolvencies/bankruptcies that occur with other companies in the life insurance industry. Some states permit member insurers to recover assessments paid through full or partial premium tax offsets. These charges neither relate to the ordinary course of the Company’s business nor reflect the Company’s underlying business performance, but result from external situations not controlled by the Company. The Company excludes any charges associated with U.S. guaranty fund assessments and the corresponding tax benefit or expense from adjusted earnings.

In Japan, the government also requires the insurance industry to contribute to a policyholder protection corporation that provides funds for the policyholders of insolvent insurers; however, these costs are calculated and administered differently than in the U.S. In Japan, these costs are not directly related to specific insolvencies or bankruptcies, but are rather a regular operational cost for an insurance company. Based on this structure, the Company does not remove the Japan policyholder protection expenses from adjusted earnings.

Nonrecurring items also include conversion costs related to legally converting the Company's Japan business to a subsidiary; these costs primarily consist of expenditures for legal, accounting, consulting, integration of systems and processes and other similar services. These Japan branch conversion costs were an immaterial amount for the year-ended December 31, 2019 and $75 million for the year-ended December 31, 2018.

Income Taxes

The Company's combined U.S. and Japanese effective income tax rate on pretax earnings was 25.7% in 2019 and 26.7% in 2018. The decrease in the U.S. federal statutory corporate income tax rate from 35% to 21% effective January 1, 2018 drove the reduction in the effective tax rate for 2019 and 2018. Total income taxes were $1.1 billion in both 2019 and 2018. Japanese income taxes on Aflac Japan's results account for most of the Company's consolidated income tax expense.

The traditional channels through which Aflac Japan has sold its products consist ofTraditional Sales ChannelThis distribution channel includes individual agents/agencies, independent corporate agencies and affiliated corporate agencies. The individual agencies and independent corporate agencies that sell Aflac Japan's products give better access to workers at a vast number of small businesses in Japan. Agents' activities are primarily focused on insurance sales, with customer service support provided by the Aflac Contact Center. Affiliated corporate agencies are originally formed when companies establish subsidiary businesses to sell Aflac Japan's insurance products to its employees as part of a benefit package, and then expand to sell Aflac Japan products to other parties such as suppliers and customers.Thesewas represented by more than 9,000 sales agencies help Aflacat the end of 2019, with more than 109,000 licensed sales associates employed by those agencies, including individual agencies.

BanksConsumers in Japan reach employees at large worksites, and some of them are also successful in approaching customers outside their business groups. The Company believes that new agencies will continue to be attracted to Aflac Japan's competitive commissions, attractive products, superior customer service and strong brand image.

(JPI) offers Aflac Japan has more banks selling its supplemental health insurancecancer products than any of its competitors. Japanese consumers rely on banks to provide traditional bank services, and also to provide insurance solutions and other services. The Company believes Aflac Japan's long-standing and strong relationships within the

Japanese banking sector, along with its strategic preparations, have proven to be an advantage, particularly starting when this channel opened up for its products. Aflac Japan's partnerships throughout the banking sector provide Aflac Japan with a wider demographic of potential customers than it would otherwise have been able to reach, and it also allows banks to expand their product and service offerings to consumers.
In 2005, legislation aimed at privatizing Japan's postal system (Japan Post) was enacted into law. The privatization laws split Japan Post into four operating entities that began operating in October 2007. In 2007, one of these entities selected Aflac Japan as its provider of cancer insurance to be sold through its post offices, and, in 2008, Aflac Japan began selling cancer insurance through these post76 directly managed sales offices. Japan Post has historically beenIn 2018, the Company’ entered a popular place for consumers to purchase insurance products. Legislation to reform the postal system passed Japan’s legislature, the Diet, in April 2012 and resulted in the merger of two of the postal operating entities (the one that delivers the mail and the one that runs the post offices) in October 2012. In July 2013, Aflac Japan entered into a new agreementstrategic alliance with Japan Post Holdings to further expandCo., Ltd. (Japan Post Holdings), the partnership that was established in 2008.

U.S.
As of December 31, 2017, the U.S. sales force was composed of sales associates and brokers who are licensed to sell accident and health insurance. Many are also licensed to sell life insurance. Aflac U.S. utilizes dual-channel distribution to market its insurance products to businesses of all sizes. The career agent channel focuses on marketing Aflac to the small business market, which consists of employers with less than 100 employees. As such, Aflac U.S. has aligned its recruiting, training, compensation, marketing and incentives for its career agents to encourage specific activity and sales of individual policies in this market. The broker channel focuses on selling to the mid- and large-case market, which is comprised of employers with more than 100 employees and typically an average size of 1,000 employees or more. Since regional and national brokers have traditionally served the mid- and large-case market, the highly trained and experienced sales professionals of the broker channel are assigned a geographic market to strengthen relationships with the top brokers and sell Aflac products to their clients. As a result, Aflac U.S. is represented on 160 benefit administration platforms, sometimes referred to as exchanges, of various brokers.

Sales associates and brokers are independent contractors and are paid commissions based on first-year and renewal premiums from their sales of insurance products. In addition to receiving commissions on personal production, district and regional sales coordinators may also receive override commissions and incentive bonuses.

Aflac U.S. has continued to evolve its career and broker management infrastructure to drive growth in sales. In 2017, Aflac hired a Chief Distribution Officer to align the strategies of career and broker channels and to further expand U.S. distribution. All Aflac U.S. sales channels are now within the organizational structure of the Chief Distribution Officer. Prior to this change, the broker and career channels were part of separate organizational structures. Aflac U.S. believes the addition of this role will enhance performance management and augment its long-term sales strategy.

Aflac U.S. concentrates on marketing its insurance products at the worksite. This method offers policies to individuals through employment, trade and other associations. Historically, Aflac U.S. policies have been individually underwritten, however over the past several years, guaranteed issue options have become available. Premiums are generally paid by the employee. Additionally, Aflac's individual policies are portable, meaning that individuals may retain their full insurance coverage upon separation from employment or such affiliation, generally at the same premium. Aflac U.S. collects a major portion of premiums on such sales through payroll deduction or other forms of centralized billing. With Aflac U.S. brokerage sales expansion and CAIC, branded as Aflac Group Insurance, Aflac U.S. offers group voluntary insurance products desired by many large employers. These products are sold on a group basis and often have some element of guaranteed issue. Worksite marketing enables sales associates and brokers to reach a greater number of prospective policyholders and lowers distribution costs, compared with individually marketed business.

Competition
Japan
In 1974, Aflac was granted an operating license to sell lifeThe Company competes with other insurance in Japan, making Aflac the second non-Japanese life insurance company to gain direct access to the Japanese insurance market. Through 1981, Aflac Japan faced limited competition for cancer insurance policy sales. However, Japan has experienced two periods of deregulation since Aflac Japan entered the market. The first came in the early 1980s, when nine mid-sized insurers, including domesticcarriers through policyholder service, price, product design and foreign companies, were allowed to sell cancer insurance products for the first time. The second period began in 2001 when all life and non-life insurers were allowed to sell stand-alone cancer and medical insurance productssales efforts, as well as other stand-alone health insurance products. As a result, the number of insurance companies offering stand-alone cancer and medical insurance has more than doubled since the deregulation of the Japan market was deregulated in 2001. However, based on Aflac Japan's growth of annualized premiums in force and agencies,diversified distribution network, the Company does not believe that Aflac Japan's market-leading position has been significantly impacted by increased competition. Furthermore, the Company believes the continued development and maintenance of operating efficiencies will allow Aflac Japan to offer affordable products that appeal to consumers. Aflac is the largest life insurer in Japan in terms of cancer and medical policies in force. As of December 31, 2017, Aflac Japan exceeded 24 million individual policies in force in Japan.

Aflac has had substantial success selling cancer policies in Japan, with more than 15 millioncancer policies in force as of December 31, 2017. Aflac continued to be the number one seller of cancer insurance policies in Japan throughout 2017. The Company believes Aflac Japan will remain a leading provider of cancer and medical insurance coverage in Japan, principally due to its experience in the market, well-known brand, low-cost operations, expansive marketing system (see Distribution - Japan above) and product expertise.

Aflac Japan has also experienced substantial success selling medical insurance in Japan. While other companies have recognized the opportunities that Aflac Japan has seen in the medical insurance market and offered new products, Aflac Japan endeavors to make its products stand out for their value to consumers.

U.S.
Aflac competes against several voluntary supplemental insurance carriers on a national and regional basis. Aflac U.S. believes its policies, premium rates, platforms, value-added services and sales commissions are competitive by product type. Moreover, Aflac U.S. believes that Aflac products are distinct from competitive offerings given its product focus (including features, benefits, and its claims service model), distribution capabilities, and brand awareness. For many companies with which Aflac U.S. competes, voluntary supplemental insurance products are sold as a secondary business. A growing number of major medical and life insurance carriers are also entering into the voluntary supplemental insurance market. For Aflac U.S., supplemental insurance products are its primary business and are sold via a distribution network of independent sales associates and brokers (see U.S. Distribution above). In addition, the Company believes that advertising campaigns for Aflac U.S. have increased name awareness and understanding among consumers and businesses of the value its products provide.

Both private and publicly-traded insurers offer major medical insurance for hospitalization and medical expenses. Much of this insurance is sold on a group basis to accounts that are both fully and self-insured. The federal and state governments also pay substantial costs of medical treatment through various programs. Major medical insurance generally covers a substantial portion of the medical expenses incurred by an insured. Aflac policies are designed to provide coverage that supplements major medical insurance by paying cash directly to the policyholder to use for expenses their major medical insurance is not designed to cover, or for any other uses that the policyholder chooses. Thus, Aflac U.S. does not compete directly with major medical insurers except those who sell supplemental insurance products as a secondary business. Any reduction of coverage, increase in employee participation costs, or increased deductibles and copayments by major medical commercial or government insurance carriers could favorably affect Aflac U.S. business opportunities. Since the implementation of the Affordable Care Act (ACA)beginning in 2010, some employers have shifted a larger burden of the cost of care to their employees, primarily through increases in premiums, copays, and/or deductibles, such as through the use of high-deductible health plans. In addition, the Company believes that some employers have made increasing use of supplemental insurance product offerings in order to improve their competitiveness in employee recruitment and retention.


7



Since Aflac products provide an additional level of financial protection for policyholders, the Company believes the increased financial exposure some employees may face creates a favorable opportunity for Aflac U.S. products. However, given the profitability erosion some major medical carriers are facing in their core lines of business, the Company has seen a more competitive landscape as they seek entry into Aflac's supplemental product segments and leverage their core benefit offerings by bundling and discounting products in order to gain voluntary market share.

One Day PaySM is a claims initiative that Aflac U.S. introduced in 2015 to process, approve and pay eligible claims in just one day. The Company believes that along with its brand and relevant products, this claims practice has helped Aflac stand out from competitors.

Investments

Japan

The Company’s investment strategy with respect to Aflac Japan utilizes disciplined asset and liability management while seeking diversification, long-term risk-adjusted investment returns and the delivery of stable income within regulatory and capital objectives, as well as preserving shareholder value in the Aflac Japan business.

In attempting to optimally balance these objectives, the Company seeks to maintain on behalf of Aflac Japan a diversified portfolio of yen-denominated investment assets, U.S. dollar-denominated investment portfolio hedged back to yen and a portfolio of unhedged U.S. dollar-denominated assets. Each of these portfolios presents unique benefits and risks to the Company.

Yen-denominated investments included in Aflac Japan’s portfolio primarily consist of Japan Government Bonds (JGB), other public bonds and private placement fixed income instruments. The Company attempts to match both the duration and currency of these assets with Aflac Japan’s liabilities. This poses a difficulty in Aflac Japan due to the lack of suitable long-dated yen-denominated fixed income instruments. In 2012, the Company initiated a strategic approach to include U.S. dollar-denominated investments in Aflac Japan’s portfolio with the initial intent that they would be coupled with foreign exchange hedges. Today, this hedged U.S. dollar-denominated investment portfolio is mainly invested in long-term fixed and floating-rate loans and long-term investment-grade and high-yield fixed income securities. The primary goals of the yen-denominated and hedged U.S. dollar portfolios are to provide sufficient yen cash flows to support the insurance liabilities and other yen-denominated obligations of Aflac Japan, and to seek appropriate long-term risk-adjusted investment returns supportive of solvency margin ratio (SMR) levels that provide sufficient repatriation and dividend flows to the Parent Company. The hedges supporting this portion of the U.S.-dollar portfolio pose derivative rollover risk that could amplify hedge costs in unfavorable market conditions, risk of counterparty default, and may require the Company to post collateral. In a declining yen environment, these hedges are attended by negative cash settlements that may significantly increase liquidity requirements, thereby shifting funds away from other capital management opportunities including loss of investment income. If over long term the combined yen-denominated and hedged U.S.-dollar portfolios are too large relative to the Aflac Japan’s yen obligations, this may erode the economic value of these portfolios under a long-term scenario of weakening yen due to foreign currency translation risk which may emerge over time in the form of reduced repatriation and dividend capacity.

The Company also maintains an unhedged U.S. dollar-denominated investment portfolio with the objectives of generating enhanced investment returns and mitigating certain of the risks posed by the yen and hedged U.S. dollar-denominated portfolios as outlined above. Further, the Company has determined that the unhedged portfolio acts as a natural economic currency hedge of a portion of the Company’s investment in Aflac Japan against erosion of economic value. However, the unhedged U.S. dollar-denominated investment portfolio creates an unmatched foreign currency exposure and subjects Aflac Japan to volatility in regulatory capital and earnings, which may adversely impact Aflac Japan’s ability to pay dividends to the Parent Company. The Company’s approach to sizing the unhedged U.S. dollar-denominated investment portfolio seeks to balance the unique risks presented by each of the three portfolios outlined above, but the overall investment strategy in Aflac Japan is guided primarily by the objective of securing the long-term financial strength of Aflac Japan and funding of yen liabilities. As a result, the Company has historically maintained and currently maintains the size of the unhedged portfolio at levels below the stressed economic surplus in Aflac Japan.

The determination of stressed economic surplus in Aflac Japan involves multiple models using multiple statistical approaches and assuming various economic and operating scenarios that are stressed to arrive at a range of potential outcomes. This range does not account for all economic scenarios, some of which may result in values outside of the range. The Company periodically assesses the stressed economic surplus in Aflac Japan, which fluctuates over time, and adjusts the size of the unhedged portfolio accordingly. The portfolio may include medium-term and long-term fixed-rate government and corporate (investment-grade and high-yield) bonds, floating-rate loans, public equities, and alternative

asset classes. In determining the composition of the portfolio, the Company also considers diversification, hedge cost, investment returns relative to yen-denominated investment yields, and Aflac Japan capital requirements. At December 31, 2017, this unhedged U.S. dollar-denominated portfolio was approximately $13.0 billion, compared with approximately $8.6 billion at December 31, 2016. For additional discussion of business and market risks associated with the Company’s investment strategy in Japan, refer to the Risk Factors and Quantitative and Qualitative Disclosures about Market Risk sections.

U.S.

The Company’s investment strategy with respect to Aflac U.S. utilizes disciplined asset and liability management while seeking long-term risk-adjusted investment returns and the delivery of stable income within regulatory and capital objectives. As part of the Company's portfolio management and asset allocation process, Aflac U.S. invests in fixed-maturity investments and growth assets, including public equities and alternative investments in limited partnerships. Aflac U.S. has been investing in both publicly traded and privately originated investment-grade and below-investment-grade fixed-maturity securities and loans.

Regulation


Japan

Financial Services Agency (FSA)The financial and business affairs of Aflac Japan are subject to examination by Japan's FSA. Aflac Japan files annual reports and financial statements for the Japanese insurance operations based on a March 31 fiscal year end, prepared in accordance with Japanese regulatory accounting practices prescribed or permitted by the FSA. Japanese regulatory basis earnings are determined using accounting principles that differ materially from U.S. GAAP. For example, under Japanese regulatorygenerally

4





accepted accounting practices, policy acquisition costs are expensed immediately; policy benefit and claim reserving methods and assumptions are different; premium income is recognized on a cash basis; different consolidation criteria apply to variable interest entities (VIEs); different accounting applies to reinsurance; and investments can have a separate accounting classification and treatment referred to as policy reserve matching bonds (PRM)principles (U.S. GAAP). Capital and surplus of Aflac Japan, based on Japanese regulatory accounting practices, was $6.7$7.8 billion at December 31, 2017,2019, compared with $5.6$6.4 billion at December 31, 2016.2018. Two FSA regulations applicable to Aflac Japan are outlined below.


Privacy and Cybersecurity
With regard to personal information obtained from policyholders, the insured, or others, Aflac Japan is regulated in Japan by the Act on the Protection of Personal Information (APPI) and guidelines issued by FSA and other governmental authorities. The FSA updated its guidelines regarding cybersecurity in October 2018.

FSA Solvency Standard
The FSA maintains a solvency standard, the solvency margin ratio (SMR), which is used by Japanese regulators to monitor the financial strength of insurance companies. As of December 31, 2017,2019, Aflac Japan's SMR was 1,064%1,043%, compared with 945%965% at December 31, 2016.2018. Aflac Japan's SMR is sensitive to interest rate, credit spread and foreign exchange rate changes. See the Liquidity and Capital Resources and Liquidity Sectionsection of the MD&A for a discussion of measures the Company has taken to mitigate the sensitivity of Aflac Japan's SMR.


Japan Company LawAs abranch of Aflac prior to April 1, 2018, Aflac Japan typically repatriatesrepatriated a portion of its accumulated earnings, as determined on a Japanese regulatory accounting basis, to Aflac U.S. provided that Aflac Japan hashad determined that it adequately protected policyholders' interests as measured by its SMR. The FSA may not allow profit repatriations to Aflac U.S. ifAfter the transfers would cause Aflac Japan to lack sufficient financial strength for the protection of Japanese policyholders. In the near term, the Company does not expect these requirements to adversely affect the funds available for profit repatriations, nor does the Company expect these requirements to adversely affect the funds available for payments of allocated expenses to Aflac U.S. and management fees to the Parent Company. Upon conversion of Aflac Japan to a subsidiary structure which the Company anticipates completing as early ason April 1, 2018 and starting in the new subsidiary will distributefourth quarter of 2018, Aflac Japan distributes dividends instead of internal profit repatriation.to the Parent Company. Such dividends will beare subject to permitted dividend capacity under the Japan Company Law.


Policyholder ProtectionThe Japanese insurance industry has a policyholder protection corporation that provides funds for the policyholders of insolvent insurers. For additional information, regardingsee the policyholder protection fund, seesection of the Policyholder Protection subsection of MD&A in this report.&A.
In June 2013, a revision to the Financial Instruments and Exchange Act established a post-funded Orderly Resolution Regime for financial institutions to prevent a financial crisis in the event of a financial institution’s failure. This regime came into effect in March 2014 and has not had, and is not expected to have, a material impact on the Company's operations in Japan.

As a branch of Aflac's principal insurance subsidiary, Aflac Japan is also subject to regulation and supervision in the United States (see U.S. Regulation below). For additional information regarding Aflac Japan's operations and regulations, see the Aflac"Aflac Japan SegmentSegment" subsection of MD&A and Notes 2 and 13 of the Notes to the Consolidated Financial Statements in this report.


AFLAC U.S.
General
The Company designs its U.S. insurance products to provide supplemental coverage for people who already have major medical or primary insurance coverage, as Aflac U.S. insurance policies pay benefits regardless of other insurance. Aflac U.S. products are distributed in the individual and group supplemental insurance markets. Aflac's individual policies are portable, meaning that individuals may retain their full insurance coverage upon separation from employment or affiliation with a group, generally at the same premium. Individual policies are typically guaranteed-renewable for the lifetime of the policyholder (to age 75 for short-term disability policies).

Cancer InsuranceAflac U.S.'s cancer insurance products provide a lump-sum benefit upon initial diagnosis of cancer and subsequent benefits for treatment received due to cancer. Aflac U.S. offers cancer insurance on an individual basis.

Accident InsuranceAflac U.S. offers accident coverage on both an individual and group basis. These policies pay cash benefits in the event of a covered injury. The accident portion of the policy includes lump-sum benefits for accidental death, dismemberment and specific injuries as well as fixed benefits for hospital confinement. Additional benefits are also available for home modifications, wellness and increased benefits for injuries related to participations in an organized sporting activity.

Short-Term Disability InsuranceAflac U.S. offers short-term disability benefits on both an individual and group basis. The individual short-term disability product offers an Aflac Value Rider that pays a benefit, less claims, for every consecutive five-year term that the policy is in force.

Critical Illness InsuranceAflac U.S. offers coverage for critical illness plans on both an individual and group basis. These policies are designed to pay cash benefits in the event of critical illnesses such as heart attack, stroke or cancer.


5





Hospital Indemnity InsuranceAflac U.S. offers hospital indemnity coverage on both an individual and group basis. Hospital indemnity products provide policyholders fixed dollar benefits triggered by hospitalization due to accident or sickness. Indemnity benefits for inpatient and outpatient surgeries, as well as various other diagnostic events, are also available. Aflac U.S. also offers a lump sum rider for a range of critical illness events that can be added to its individual accident, short-term disability and hospital indemnity products.

Dental and Vision Insurance Aflac U.S. now offers network dental and vision products on a group basis. Aflac U.S. offers fixed-benefit dental coverage on both an individual and group basis. Aflac U.S. offers Vision NowSM, an individually issued policy which provides benefits for serious eye health conditions and loss of sight as well as coverage for corrective eye materials and exam benefits.

Life (Term and Whole)Aflac U.S. offers term- and whole-life policies on both an individual and group basis.

Distribution Channels

Independent Associates/Career AgentsThe career agent channel in Aflac U.S. focuses on marketing Aflac to the small business market, defined as employers of between three and 99 employees. Sales associates in the U.S. are independent contractors and are paid commissions and other variable compensation based on first-year and renewal premiums from their sales of insurance products.

BrokersThe broker channel of Aflac U.S. focuses on selling to the mid- and large-case market, which is comprised of employers with 100 or more employees and typically an average size of 1,000 employees or more. Brokers in the U.S. are independent contractors and are paid commissions based on first-year and renewal premiums from their sales of insurance products.

Aflac U.S. concentrates on marketing its insurance products at the worksite. This method offers policies to individuals through employment, trade and other associations. Aflac U.S. believes that worksite marketing enables sales associates and brokers to reach a greater number of prospective policyholders and lowers distribution costs, compared with individually marketed business. Aflac U.S. is also expanding its distribution strategy to reach consumers outside of the traditional worksite through digital lead generation.

Competition

Aflac U.S. competes against several supplemental insurance carriers on a national and regional basis. Aflac U.S. believes its policies, premium rates, platforms, value-added services and sales commissions are competitive by product type. Moreover, Aflac U.S. believes that its products are distinct from competitive offerings given its product focus (including features, benefits and claims service model), distribution capabilities and brand awareness. 

Since Aflac products provide an additional level of financial protection for policyholders, the Company believes the increased financial exposure some employees may face creates a favorable opportunity for Aflac U.S. products. However, given the profitability erosion some major medical carriers are facing in their core lines of business, the Company has seen a more competitive landscape as these carriers seek entry into Aflac's supplemental product segments and leverage their core benefit offerings by bundling and discounting products in order to gain market share.

One Day PaySM is a claims initiative that Aflac U.S. has focused on to process, approve and pay eligible claims in just one day. The Company believes that this claims practice enhances the Aflac U.S. brand reputation and the trust policyholders have in Aflac, and it helps Aflac stand out from competitors.

Regulation

Insurance RegulationThe Parent Company and its U.S. insurance subsidiaries, Aflac, (a Nebraska-domiciledCAIC, TOIC (Nebraska-domiciled insurance company), American Family Life Assurance Company ofcompanies) and Aflac New York (Aflac New York, a(a New York-domiciled insurance company) and CAIC (redomiciled from South Carolina to Nebraska effective December 2016) are subject to state regulations in the United StatesU.S. as an insurance holding company system. Such regulations generally provide that transactions between companies within the holding company system must be fair and equitable. In addition, transfers of assets among such affiliated companies, certain dividend payments from insurance subsidiaries and materialcertain transactions between companies within the system, including management fees, loans and advances are subject to prior notice to, or approval by, state regulatory authorities. These laws generally require, among other things, the insurance holding company and each insurance company directly owned by the holding company to register with the insurance departments of their respective domiciliary states and to furnish annually financial and other information about the operations of companies within the holding company system.

Like all U.S. insurance companies, Aflac, isAflac New York, CAIC and TOIC are subject to regulation and supervision in the jurisdictions in which it doesthey do business. In general, the insurance laws of the various jurisdictions establish supervisory agencies with broad administrative powers relating to, among other things:

granting and revoking licenses to transact business
regulating trade and claims practices
licensing of insurance agents and brokers
approval of policy forms and premium rates
standards of solvency and maintenance of specified policy benefit reserves and minimum loss ratio requirements
capital requirements
limitations on dividends to shareholders
the nature of and limitations on investments
deposits of securities for the benefit of policyholders
filing of financial statements prepared in accordance with statutory insurance accounting practices prescribed or permitted by regulatory authorities
periodic examinations of the market conduct, financial, and other affairs of insurance companies

The insurance laws of Nebraska that govern Aflac's activities provide that the acquisition or change of “control” of a domestic insurer or of any person that controls a domestic insurer cannot be consummated without the prior approval of the Nebraska Department of Insurance.Insurance (NDOI). A person seeking to acquire control, directly or indirectly, of a domestic insurance company or of any person controlling a domestic insurance company (in the case of Aflac, CAIC and TOIC, the Parent Company) must generally file with the Nebraska Department of Insurance (NDOI)NDOI an application for change of control containing certain information required by statute and published regulations and provide a copy to Aflac. In Nebraska, control is generally presumed to exist if any person, directly or indirectly, acquires 10% or more of an insurance company or of any other person or entity controlling the insurance company. The 10% presumption is not conclusive and control may be found to exist at less than 10%. Similar laws apply in New York, the domiciliary jurisdiction of Aflac's New York insurance subsidiary.

State insurance departments conduct periodic examinations of the books and records, financial reporting, policy filings and market conduct of insurance companies domiciled in their states, generally once every three to five years. Examinations are generally carried out in cooperation with the insurance departments of other states under guidelines promulgated by the National Association of Insurance Commissioners (NAIC). In 2016, full-scope, risk-focused financial examinations were conducted by the NDOI, New York Department of Financial Services (NYDFS), and the South Carolina Department of Insurance (SCDOI) on their state domiciled insurance entities American Family Life Assurance Company of Columbus, American Family Life Assurance Company ofAflac, Aflac New York, and Continental American Insurance Company,CAIC, respectively. The NDOI and NYDFS exams covered a four-year period ending December 31, 2015, whereas the SCDOI

10



exam covered a five-year period ending December 31, 2015. There were no material findings contained in the NDOI, NYDFS and SCDOI final exam reports. CAIC redomiciled to Nebraska as of December 2016 and TOIC redomiciled to Nebraska effective March 11, 2019. The NDOI and NYDFS are scheduled to conduct a full-scope comprehensive financial examination covering years 2016-2019 in 2020.


NAIC Risk-Based CapitalThe NAIC continually reviews regulatory matters,, such as risk-based capital (RBC) modernization, group capital calculations, liquidity risk assessment and principle-based reserving, and recommends changes and revisions for adoption by state legislators and insurance departments.reserving. The NAIC has adopted a valuation manual containing a principle-based approach to calculation of life insurance reserves. The valuation manual became effective January 1, 2017. There is a three-year transition period, beginning January 1, 2017, during which companies can choose on a product by product basis to implement principle-based reserving for new business. ThereThe Company anticipates that the adoption of this manual will be nonot cause a material impact on ourthe statutory reserves.reserves of Aflac, Aflac New York, CAIC or TOIC. The NAIC uses a risk-based capitalan RBC formula relating to insurance risk, business risk, asset risk and interest rate risk to facilitate identification by insurance regulators of inadequately capitalized insurance companies based upon the types and mix of risk inherent in the insurer's operations. The formulas for determining the amount of risk-based capitalRBC specify various weighting factors that are applied to financial balances or various levels of activity based on the perceived degree of risk. Regulatory compliance is determined by a ratio of a company's regulatory total adjusted capital to its authorized control level risk-based capitalRBC as defined by the NAIC. Companies below specific trigger points or ratios are classified within certain levels, each of which requires specified corrective action. The levels are company action, regulatory action, authorized control, and mandatory control. Aflac's NAIC risk-based capital ratio remains high and reflects a very strong capital and surplus position. As of December 31, 2017,2019, based on year-end statutory accounting results, Aflac's company action level RBC ratio was 831%539%. The 2018 RBC as filed is lower than Aflac U.S. stand-alone RBC due to the inclusion of Aflac Japan for the first quarter of 2018. The RBC charge reflects the business risk without any total adjusted capital (TAC). Aflac's NAIC RBC ratio remains high and reflects a very strong capital and surplus position.


Guaranty Association and Similar ArrangementsUnder state insurance guaranty association laws and similar laws in international jurisdictions, the Company is subject to assessments, based on the share of business the Company writes in the relevant jurisdiction, for certain obligations of insolvent insurance companies to policyholders and claimants. In the United States,U.S., some states permit member insurers to recover assessments paid through full or partial premium tax offsets. The Company's policy is to accrue assessments when the entity for which the insolvency relates has met its state of domicile's statutory

definition of insolvency, the amount of the loss is reasonably estimable and the related premium upon which the assessment is based is written. In most states, the definition is met with a declaration of financial insolvency by a court of competent jurisdiction. For additional information regarding state insurance guaranty assessments, see the U.S. Regulatory Environment subsection of MD&A in this report.


Healthcare Reform Legislation

Federal InitiativesFederal legislation and administrative policies in several areas, including health care reform legislation, financial services reform legislation, securities regulation, pension regulation, privacy, tort reform legislation and taxation, can significantly and adversely affect insurance companies. For example, theFederal regulations applicable to Aflac U.S. are outlined below.

Affordable Care Act (ACA)
The ACA, federal health care reform legislation, gave the U.S. federal government direct regulatory authority over the business of health insurance. The reform included major changes to the U.S. health care insurance marketplace. Among other changes, the reform legislation included an individual medical insurance coverage mandate (which has since been repealed effective 2019 by the Tax Act, discussed below), provided for penalties on certain employers for failing to provide adequate coverage, created health insurance exchanges, and addressed coverage and exclusions as well as medical loss ratios. It also imposed an excise tax on certain high cost plans, known as the “Cadillac tax,” that is currently scheduled to begin in 2020. The legislation also included changes in government reimbursements and tax credits for individuals and employers and alters federal and state regulation of health insurers. The ACA, as enacted, does not require material changes in the design of the Company's insurance products. However, indirect consequences of the legislation and regulations could present challenges that could potentially have an impact on the Company's sales model, financial condition and results of operations. The United StatesU.S. Congress has considered and may continue to consider legislation that would repeal and replace key provisions of the ACA. There can be no assurance that any legislation affecting the ACA will be passed by Congress, nor as to the ultimate timing or provisions of any such legislation, nor as to the effect of any such legislation on the design or marketability of the Company's insurance products.

Tax Reform Legislation

A budget reconciliation act commonly referred to as the Tax Cuts and Job Act (Tax Act) was signed into law on December 22, 2017. Among other things, effective January 1, 2018, the Tax Act reduced the U.S. federal statutory corporate income tax rate from 35% to 21%, eliminated or reduced Further, certain deductions and credits, and limited the deductibility of interest expense and executive compensation.

The Tax Act also transitions international corporate taxation from a worldwide system to a modified territorial system, which in lightprovisions of the current tax treatment of Aflac Japan as a branch has the effect of subjecting the earnings of Aflac Japan to Japan taxationACA have been and subjecting the Company’s other earnings, including the consolidated earnings of the Parent Company, to U.S. taxation.

Because changessubject to tax rates are accounted for inchallenge through litigation, the periodultimate effects of enactment, during the period ended December 31, 2017, the Company revalued its deferred tax assets and liabilities and recorded, as the Company’s reasonable estimate, a net deferred tax liability reduction of $1.9 billion as of that date.

Dodd-Frank Act

Title VII of the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 (Dodd-Frank) and regulations issued thereunder, in particular rules to require central clearing for certain types of derivatives, may have an impact on Aflac'sthe Company's derivative activity, including activity on behalf of Aflac Japan. In addition, in 2015 and 2016, six U.S. financial regulators, including the U.S. Commodity Futures Trading Commission (CFTC), issued final rules regarding the exchange of initial margin (IM) and variation margin (VM) for uncleared swaps that impose greater obligations on swap dealers regarding uncleared swaps with certain counterparties, such as Aflac. The requirements of such rules with respect to VM, as well as similar regulations in Europe, became effective on March 1, 2017. Full compliance with respect to all counterparties was required by September 1, 2017.the Company. The requirements of such rules with respect to IM are currently being phased in and will be fully implemented by September 1, 2020. In October of 2017, the CFTC and the European Commission each finalized comparability determinations that permit certain swap dealers who are subject2020, although an extension to both regulatory margin regimes to take advantage of substituted compliance by complyingSeptember 1, 2021 is expected for covered entities with one set of margin requirements.an aggregate average notional amount below $50 billion. The margin requirements are expected to result in more stringent collateral requirements and to affect other aspects of Aflac's derivativesthe Company's derivative activity.


The Dodd-Frank Act also established a Federal Insurance Office (FIO) under the U.S. Treasury Department to monitor all aspects of the insurance industry and of lines of business other than certain health insurance, certain long-term care insurance and crop insurance. Traditionally, U.S. insurance companies have been regulated primarily by state insurance departments. The FIO does not directly regulate the insurance industry, but under Dodd FrankDodd-Frank it has the power to preempt state insurance regulations that are inconsistent with international agreements reached by the federal government, subject to certain requirements and restrictions. In December 2013, the FIO released a report entitled "How To Modernize And Improve The System Of Insurance Regulation In The United States." The report was required by the Dodd-Frank Act, and included 18 recommended areas of near-term reform for the states, including addressing capital adequacy and safety/soundness issues, reform of insurer resolution practices, and reform of marketplace regulation. The report also listed nine recommended areas for direct federal involvement in insurance regulation. Some of the recommendations outlined in the FIO report released in December 2013 have been implemented. The National Association of Registered Agents and Brokers Reform Act, signed into law in January 2015, simplifies the agent and broker licensing process across state lines. The FIO has also engagedand certain federal agencies must achieve consensus positions with the supervisory colleges to monitor financial stability and identify regulatory gaps for large national and internationally active insurers.

state insurance regulators when taking positions on insurance proposals by certain international forums. The presidential administration in the United StatesPresident and Congress have stated proposals to reform or repeal certain provisions of the Dodd-Frank Act, some of which have been implemented. Several proposals have been introduced, including proposals to limit or repeal the Financial Stability Oversight Council's (the Council) ability to designate nonbank financial companies as Systemically Important Financial Institutions (SIFI), eliminate the FIO, and increase Congressional oversight of the regulation issuing process. The Company cannot predict with any degree of certainty what impact, if any, such proposals willmight have on Aflac's business, financial condition, or results of operations.


Further InformationPrivacy and Cybersecurity

The collection, maintenance, use, protection, disclosure and disposal of individually identifiable data by the Company's businesses are regulated at the international, federal and state levels. These laws and rules are subject to change by legislation or administrative or judicial interpretation. Various state laws address the unauthorized access and acquisition of personal information and the use and disclosure of individually identifiable health data to the extent they are more restrictive than those contained in the privacy and security provisions in the federal Gramm-Leach-Bliley Act of 1999 (GLBA) and in the Health Insurance Portability and Accountability Act of 1996 (HIPAA). For example, the California Consumer Privacy Act became effective January 1, 2020 and requires businesses to provide California consumers rights to access, delete, and restrict certain uses of their personal information. Under the law, the California Attorney General may not bring an enforcement action prior to July 1, 2020. HIPAA also requires that the Company imposes privacy and security requirements on its business associates (as such term is defined in the HIPAA regulations).

Cybersecurity also continues to be an area of evolving focus for U.S. legislation and regulatory activity. In March 2017, new cybersecurity regulation issued by the NYDFS went into effect that requires covered entities, including Aflac New York, to maintain an information security program meeting certain security, data disposal, audit, activity

8





monitoring, and data encryption requirements. In October 2017, the NAIC adopted an Insurance Data Security Model Law that may be adopted in whole or in part by U.S. states in which the Company’s subsidiaries are licensed. Other states have adopted and, the Company expects, will continue to pass legislation and issue regulations related to cybersecurity. The Company anticipates, assesses and if necessary modifies its information security program to accommodate such changes.

Difficult conditionsSales of the Company's products and services are dependent on its ability to attract, retain and support a network of qualified sales associates, brokers and employees in global capital marketsthe U.S. and sales associates and other distribution partners in Japan.

The Company's sales, results of operations and financial condition could be materially adversely affected if its sales networks deteriorate or if the economyCompany does not adequately provide support, training and education for its existing network of sales associates, brokers, other distribution partners and employees. In the U.S., competition exists for sales associates and brokers with demonstrated ability. In Japan, the Company's sales results are dependent upon its relationship with sales associates and other distribution partners, including its strategic partner, Japan Post.

The Company competes with other insurers and financial institutions primarily on the basis of its products, compensation, support services and financial rating. The Company's sales associates, brokers and other distribution partners are independent contractors and may sell products of its competitors. If the Company's competitors offer products that are more attractive, or pay higher commissions than the Company does, any or all of these distribution partners may concentrate their efforts on selling the Company's competitors' products instead of the Company's. In addition to the Company's commissioned sales force in the U.S., Aflac has expanded its sales leadership team to include a salaried sales force of over 200 market directors and broker sales professionals. The Company's inability to attract and retain qualified sales associates, brokers and other distribution partners, including its alliance partners in Japan, could have a material adverse effect on the Company's investments, capital position, revenue, profitability, and liquidity and harm the Company's business.
The Company'ssales, results of operations are materially affected by conditions in the global capital markets and the global economy generally, including in its two primary operating markets of the United States and Japan. Weak global financial markets impact the value of the Company's existing investment portfolio, influence opportunities for new investments, and may contribute to generally weak economic fundamentals, which can have a negative impact on its operating activities.condition.


In recent years, global capital markets have been severely impacted by several major events. The financial crisis that began in the latter part of 2008 saw dramatic declines in investment values and weak economic conditionsAdditionally, as the global financial system came under extreme pressure. Although U.S. markets began recovering in late 2009 and 2010, Europe continued to struggle under a severely weakened banking system and investor concerns with sovereign debt levels. Following a period of unprecedented intervention by governments and central banks, including the U.S. Federal Reserve and European Central Bank (ECB), financial conditions improved from the dire conditions of the global financial crisis, global recession, and European debt crisis. More recently, global markets have experienced bouts of volatility due to a British exit from the European Union (EU) (Brexit), uncertainty surrounding Japan’s continued recovery amidst assorted policy changes, significant declines in global commodity prices including oil, divergent monetary policies in the United States versus many other developed economies and heightened concerns surrounding the Chinese economy. While capital and market conditions have been generally favorable in the last year, the prospect for increased volatility remains.

Recent activity by the government of North Korea has been the subject of increasing focus for a number of other governments, including those of the United States and Japan. Such North Korean activity and related geopolitical risk could have a significant impact on financial market conditions across the world. Under certain circumstances, government actions taken in response to the North Korean situation could have a material impact on the Company's Japan and U.S. operationsemployment markets continue to evolve, there is risk that the Company's practices regarding attracting, developing, and retaining employees may not be fully effective. Failure to successfully meet and maintain sufficient levels of employees may diminish the Company's ability to achieve its financial performance, includingand compliance objectives, both of which are time consuming and personnel-intensive.

Following the election of Shinzo Abe as Prime Ministermatters regarding sales of Japan in December 2012, the new administration adopted a new set of financial measures to stimulate the Japanese economy, including imposing negative interest rates on excess bank reserves. In a December 2014 snap-election, the ruling Liberal Democratic Party (LDP) won a landslide victory, further strengthening Mr. Abe's ability to implement economic reform and address key policy challenges. The Japanese financial markets reacted with even lower rates on Japanese Government bonds, large increases in Japanese equity market values, and a weakening of the yen relative to the U.S. dollar. More recently, as the Bank of Japan (BoJ) has signaled to hold its policy rate at zero, the Japan Government Bond (JGB) yield curve has steepened producing higher rates on longer maturity Japanese Government bonds. Prime Minister Abe’s victory in the October 2017 elections may result in the continuation of current monetary policy, but there can be no guarantee that this is the case.

WhileEvents related to the ongoing Japan Post investigation and other matters regarding sales of Japan Post Insurance products could negatively impact the Company’s sales and results of operations

As previously disclosed, in the second half of 2019 and the first quarter of 2020 there have been news reports and public comments regarding improper sales practices relating to sales of JPI products by JPI and JPC, each an affiliate of Japan Post Holdings (together with JPI and JPC, the Japan Post Group). JPC and JPI are important distribution and alliance partners of the Company, which in 2018 collectively accounted for approximately 25% of Aflac Japan’s third sector sales. On July 24, 2019, after such news reports and other public comments, the Japan Post Group announced that they had established a Special Investigative Committee comprised of independent former prosecutors to determine whether JPC and JPI sales practices with respect to JPI products had caused disadvantages to customers holding such policies that were not otherwise the result of honoring such customers’ intentions.

On December 18, 2019, the Japan Post Group issued a release discussing results of the investigation and stating that JPI had identified a number of cases involving potential violation of laws and regulations or internal rules. On the same date, the Japan Post Group stated that it would continue the investigation with a goal of completing it by March 2020. On December 27, 2019, the Japanese FSA issued three-month business suspension orders to JPC and JPI for the sale of JPI insurance products, and the Japan Ministry of Internal Affairs and Communications also issued a three-month business suspension order to JPC for the sale of JPI insurance products. Also on December 27, 2019, the Japan Post Group announced the resignation of the chief executives of Japan Post Holdings, JPC and JPI, to be effective January 5, 2020. On January 31,

11



2020, the Japan Post Group announced that its internal investigation had been expanded to additional policyholders and the investigation would continue with a goal of completing it by the end of June 2020. The Japan Post Group stated they could not comment on the expected timing for it to re-initiate sales of JPI insurance products.

Notwithstanding the JPI investigation and the three-month suspension orders promulgated by the FSA and the Japan Ministry of Internal Affairs and Communications, the sale of Aflac Japan cancer policies has continued through JPC and JPI. However, while the sale of Aflac Japan cancer insurance products is not within the scope of the suspension orders, beginning in August 2019 the Company has continued to add floating rate investments to its investment portfolio, mostexperienced a material decrease of its investment portfolio holdings are income-producing bonds that provide a fixed level of income.

It is uncertain what long-term effect these developments will have on the Company’s results of operations or financial condition, but any such effects could be material. See the Form 10-K.

The Company needs liquidity to pay its operating expenses, dividends on its common stock, interest on its debt, and liabilities.

Competition could adversely affect the Company's current resources do not meetability to increase or maintain its needs,market share or profitability.

The Company operates in a competitive environment and in an industry that is subject to ongoing changes from market pressures brought about by customer demands, legislative reform, marketing practices and changes to health care and health insurance delivery. These factors require the Company mayto anticipate market trends and make changes to differentiate the Company's products and services from those of its competitors. The Company also faces the potential of competition from existing or new companies in the U.S. and Japan that have not historically been active in the supplemental health insurance industry, but some of which have greater financial, marketing and management resources than the Company does. Further, some of these potential competitors could introduce new means of product development and delivery that disrupt the Company’s business model. Failure to anticipate market trends and/or to differentiate the Company's products and services can affect the Company's ability to retain or grow profitable lines of business. Further, as employers and brokers are increasingly requesting a full-suite of products from one insurance provider, a failure to react and adapt to these demands could result in decreased sales or market share.

The insurance market is undergoing rapid changes with frequent introductions of new technology-driven products and services. The Company's future success will depend, in part, on its ability to keep pace with the technological changes and to use technology to satisfy and grow customer demand for the Company's products and services and to create additional efficiencies in its operations. The Company expects that it will need to seek additional financing.continue making substantial investments in its technology and information systems to compete effectively and to stay current with technological changes. The Company's accessCompany may not be able to additional funding will depend on a variety of factors such as market conditions, the general availability of crediteffectively implement new technology-driven products and services or be successful in marketing these products and services to the financial services industryits customers. A failure to meet evolving customer demands through innovative product development, effective distribution channels, and its credit rating.

Should investors become concerned with any ofcontinuous investment in the Company's investment holdings, including the concentration in JGBs, its access to market sources of fundingtechnology could be negatively impacted. There is a possibility that lenders or debt investors may also become concerned if the Company incurs large investment losses or if the level of the Company's business activity decreases due to a market downturn or there are further adverse economic trends in the United States or Japan, specifically, or generally in developed markets. Similarly, the Company's access to funds may be impaired if regulatory authorities or rating agencies take negative actions. See more information on recent rating actions later in this Risk Factors section.

Broad economic factors such as consumer spending, business investment, government spending, the volatility and strength of the capital markets, and inflation all affect the business and economic environment and, indirectly, the amount and profitability of the Company's business. In an economic downturn characterized by higher unemployment, lower family income, lower corporate earnings, lower business investment and lower consumer spending, the demand for financial and insurance products could be adversely affected. This adverse effect could be particularly significant for companies such as Aflac that distribute supplemental, discretionary insurance products primarily through the worksite in the event that economic conditions result in a decrease in the number of new hireslower revenues and total employees. Adverse changes in the economy could potentially lead the Company's customers to be less inclined to purchase supplemental insurance coverage or to decide to cancel or modify existing insurance coverage,favorable policy terms and conditions, which could adversely affect the Company's premium revenue,operating results. As a result, the Company's ability to effectively compete to retain or acquire new business may be impaired, and its business, financial condition or results of operations may be adversely affected.

If future policy benefits, claims or expenses exceed those anticipated in establishing premiums and reserves, the Company's financial results would be adversely affected.

The Company establishes premiums for many of its policies on assumptions for morbidity, mortality, longevity and persistency. The Company also establishes and carries, as a liability, reserves based on estimates of how much will be required to pay for future benefits and claims on its policies. The Company calculates these reserves using various assumptions and estimates, including premiums the Company will receive over the assumed life of the policy; the timing, frequency and severity of the events covered by the insurance policy; and the investment returns on the assets the Company purchases with a portion of its net cash flow from operations.

The assumptions and estimates that the Company uses in establishing premiums and reserves depend on the Company's judgment regarding the likelihood of future events and are inherently uncertain. Many factors can cause actual outcomes to deviate from these assumptions and estimates, such as changes in incidence rates, economic conditions, changes in government healthcare policy, advances in medical technology, changes in treatment patterns, and changes in average lifespan. Accordingly, the Company cannot determine with precision the ultimate amounts that it will pay for, or the timing of payment of, actual benefits and claims or whether the assets supporting the policy liabilities will grow to the level the Company assumes prior to payment of benefits or claims. If the Company's actual experience is different from its assumptions or estimates, the Company's reserves may prove inadequate. As a result, the Company would incur a charge to earnings in the period in which it determines such a shortfall exists, which could have a material adverse effect on the Company's business, results of operations and financial condition.


12



Generally, lower mortality decreases the profitability of third sector products in Japan, as more policyholders will survive into ages where they have a higher rate of claim incidence. This assumption can impact pricing and reserving.  For instance, Japan FSA periodically requires updates to their Standard mortality tables for FSA reserves. An update to the Standard mortality tables was performed in April 2018 applicable to all business issued after that date. For business that is inforce prior to the update, the change in mortality table would not have an impact. For new issues, the updated mortality tables would be included in the Company's reserve assumptions, and slow the emergence of FSA earnings for third sector products and therefore will have an impact on pricing returns. The Company adjusts pricing assumptions as new products are developed to adjust for these mortality assumptions. 

The success of the Company's business depends in part on effective information technology systems and on continuing to develop and implement improvements in technology.

The Company's business depends in large part on its technology systems for interacting with employers, policyholders, sales associates, and brokers, and the Company's business strategy involves providing customers with easy-to-use products to meet their needs and ensuring employees have the technology in place to support those needs. Some of the Company's information technology systems and software are older, legacy-type systems that are less efficient and require an ongoing commitment of significant resources to maintain or upgrade to current standards including adequate business continuity procedures. The Company is unablein a continual state of upgrading and enhancing its business systems; however, these changes tend to predictchallenge the courseCompany's complex integrated environment. The Company's success is dependent in large part on maintaining or improving the effectiveness of existing systems and continuing to develop and enhance information systems that support its business processes in a cost-efficient manner. If the Company does not maintain the effectiveness of its systems, the Company's operations and reputation could be adversely affected and it could be exposed to litigation as well as to regulatory proceedings and fines or penalties.

Defaults, downgrades, widening credit spreads or other events impairing the value of the current recoveriesfixed maturity securities and loan receivables in the Company's investment portfolio may reduce the Company's earnings and capital position.
The Company is subject to the risk that the issuers and/or guarantors of fixed maturity securities and loan receivables the Company owns may default on principal or interest. A significant portion of the Company's portfolio represents an unsecured obligation of the issuer, including some that may be subordinated to other debt in the issuer’s capital structure. In these cases, many factors can influence the overall creditworthiness of the issuer and ultimately its ability to service and repay the Company's holdings. This can include changes in the global economy, the company's assets, strategy, or management, shifts in the dynamics of the industries in which they compete, their access to additional funding, and the overall health of the credit markets. Factors unique to the Company's securities including contractual protections such as financial marketscovenants or relative position in the recurrence, durationissuer's capital structure also influence the value of the Company's holdings.

Most of the Company's investments carry a rating by one or severitymore of disruptionsthe nationally recognized statistical rating organizations (NRSROs or rating agencies). Any change in the rating agencies' approach to evaluating credit and assigning an opinion could negatively impact the fair value of the Company's portfolio. The Company employs a team of credit analysts to monitor the creditworthiness of the issuers in its portfolio. Any credit-related declines in the fair value of positions held in the Company's portfolio believed to be not temporary in nature will negatively impact the Company's net income and capital position through impairment and other credit related losses. These losses would also affect the Company's solvency ratios in the U.S. and Japan. Aflac Japan has certain regulatory accounting requirements for realizing impairments that could be triggered by credit-related losses, which may be different from U.S. GAAP and statutory requirements. These impairment losses could negatively impact Aflac Japan's earnings, and the corresponding dividends and capital deployment.

The Company is also subject to the risk that any collateral providing credit enhancement to the Company's positions could deteriorate. These instruments may include senior secured first lien loans, such markets.as commercial mortgage loans, bank loans, middle market loans, and loan-backed securities where the underlying loan or collateral notes may default on principal, interest, or other payments, causing an adverse change in cash flows to the positions held in the Company's investment portfolio.


The Company is exposed to sovereign credit risk through instruments issued directly by governments and government entities as well as banks and other institutions that rely in part on the strength of the underlying government for their credit quality. In addition to the U.S. and Japan, many governments, especially in Europe, have been subject to rating downgrades due to the need for fiscal and budgetary remediation and structural reforms, reduced economic activity, and investment needed to support banks or other systemically important entities. Additional downgrades or default of the Company's sovereign issuers will have a negative impact on its portfolio and could reduce the Company's earnings and capital.


13



In addition to the Company's exposure to the underlying fundamental credit strength of the issuers of its fixed maturity securities and the underlying risk of default, the Company is also exposed to the general movement in credit market spreads. A widening of credit spreads could reduce the value of the Company's existing portfolio, create unrealized losses on its investment portfolio, and reduce the Company's adjusted capital position which is used in determining the SMR in Japan. This widening of credit spreads could, however, increase the net investment income on new credit investments. Conversely, a tightening of credit spreads could increase the value of the Company's existing portfolio and create unrealized gains on its investment portfolio. This tightening of credit spreads could also reduce the net investment income available to the Company on new credit investments. Increased market volatility also makes it difficult to value certain of the Company's investment holdings (see the Critical Accounting Estimates section in Item 7, Management's Discussion and Analysis, of this Form 10-K).

For more information regarding credit risk, see the Credit Risk subsection of Item 7A, Quantitative and Qualitative Disclosures about Market Risk, of this Form 10-K.

The Company is exposed to significant interest rate risk, which may adversely affect its results of operations, financial condition and liquidity.
The Company has substantial investment portfolios that support its policy liabilities. Low levels of interest rates on investments experienced in Japan and the United StatesU.S. over the last decade have reduced the level of investment income earned by the Company. The Company's overall level of investment income will be negatively impacted in a persistent low-interest-rate environment. While the Company generally seeks to maintain a diversified portfolio of fixed-income investments that reflects the cash flow and duration characteristics of the liabilities it supports, the Company may not be able to fully mitigate the interest rate risk of its assets relative to its liabilities. The Company's exposure to interest rate risk relates primarily to the ability to invest future cash flows to support the interest rate assumption made at the time the Company's products were priced and the related reserving assumptions were established. A sustained decline in interest rates could hinder the Company's ability to earn the returns assumed in the pricing and the reserving for its products at the time they were sold and issued. Due to low interest rates, the Company's ability to earn the returns it expects may also influence the Company's ability to develop and price attractive new products and could impact its overall sales levels. The Company's first sector products are more interest rate sensitive than third sector products. As discussed in Item 1. Business, beginning in 2013, Aflac Japan began to curtail sales of first sector savings-type products due to persistent low interest rates in Japan. The recentcontinuing negative interest rate imposed by the Bank of Japan (BoJ) on excess bank reserves could continue to have a negative impact on the distribution and pricing of these products.

15



A rise in interest rates could improve the Company's ability to earn higher rates of return on future investments, as well as floating rate investments held in its investment portfolio. However, an increase in the differential of short-term U.S. and Japan interest rates would increase the cost of hedging a portion of the U.S. dollar-denominated assets in the Aflac Japan segment into yen, which could have a material adverse effect on the Company's business, results of operations or financial condition. The Company’s floating rate investments typically bear interest based on the London Interbank Offered Rate (LIBOR). Regulatory and industry initiatives to eliminate LIBOR as an interest rate benchmark may create uncertainty in the valuation of LIBOR-based loans, as well as for other LIBOR-based derivatives and assets. This may adversely impact both pricing and liquidity in such instruments. The Company is unable to predict with certainty how LIBOR elimination may impact markets, pricing, liquidity and other factors or the Company's activities.
Changes in interest rates impact unrealized gains and losses of fixed income securities in the Company's investment portfolio; however, they do not have a direct impact on the related valuation of the corresponding liabilities. Prolonged periods of low interest rates, as have been experienced in recent years, heighten the risk ofassociated with future increases in interest rates because an increasing proportion of the Company's investment portfolio includes investments that bear lower rates of return than the embedded book yield of the investment portfolio. A rise in interest rates could decrease the fair value of the Company's debt and perpetual securities. Some of the insurance products that Aflac sells in the United StatesU.S. and Japan provide cash surrender values. A rise in interest rates could trigger significant policy surrenders, which might require the Company to sell investment assets and recognize unrealized losses. This situation is commonly referred to as disintermediation risk. The Company generally invests its assets to match the duration and cash flow characteristics of its policy liabilities, and therefore would not expect to realize most of these gains or losses, however, the Company's risk is that unforeseen events or economic conditions, such as changes in interest rates resulting from governmental monetary policies, domestic and international economic and political conditions, and other factors beyond the Company's control will reduce the effectiveness of this strategy. These events or economic conditions could either cause the Company to dispose of some or all of these investments prior to their maturity, or increase the risk that the issuers of these securities may default or may require impairment, which could result in the Company having to recognize such gains or losses.

14



Rising interest rates also negatively impact the SMR since unrealized losses on the available-for-sale investment portfolio factor into the ratio. For regulatory accounting purposes for Aflac Japan, there are certain requirements for realizing impairments that could be triggered by rising interest rates, negatively impacting Aflac Japan's earnings and corresponding repatriationdividends and capital deployment.
Further, interest rate risk is still an inherent portfolio, business and capital risk for the Company, and significant changes in interest rates could have a material adverse effect on the Company's consolidated results of operations, financial condition or cash flows through realized losses, impairments, changes in unrealized positions, and liquidity.


For more information regarding interest rate risk, see the Interest Rate Risk subsection within the Market Risks of Financial Instruments section of MD&A in this report.


The Company's concentration of business in Japan poses risks to its operations.
The Company's operations in Japan, including realized gains and losses on Aflac Japan's investment portfolio, accounted for 70%69% of the Company's total revenues for 2017, compared with 71% in 20162019, and 70% in 2015.both 2018 and 2017. The Japanese operations accounted for 83% of the Company's total assets at both December 31, 2017 and 2016.2019, compared with 84% at December 31, 2018.


Further, because of the concentration of the Company's business in Japan and its need for long-dated yen-denominated assets, the Company has a substantial concentration of JGBsJapan Government Bond (JGBs) in its investment portfolio. As such the Company has material exposure to the Japanese economy, geo-political climate, political regime, and other factors that generally determine a country's creditworthiness. Specifically, the nationally recognized statistical rating organizations (NRSROs, or "rating agencies"), credit rating agencies registered with the SEC, have placed increased scrutiny on JGBs, which are a significant component of the Company’s overall investment portfolio, resulting in downgrades as discussed later in this Risk Factors section. In addition, the NAIC is also considering changes to investment risk factors. Any negative developments by the NRSROs or NAIC in these areas could result in increased capital requirements for the Company.


The Company seeks to match investment currency and interest rate risk to its yen liabilities. The low level of interest rates available on yen-denominated securities has a negative effect on overall net investment income. A large portion of the cash available for reinvestment each year is deployed in yen-denominated instruments and subject to the low level of yen interest rates.


Any potential deterioration in Japan's credit quality, market access, the overall economy of Japan, or Japanese market volatility could adversely impact the business of Aflac in general and specifically Aflac Japan and its related results of operations and financial condition.


16



The Companyis exposed to foreign currency fluctuations in the yen/dollar exchange rate.

Due to the size of Aflac Japan, where functional currency is the Japanese yen, fluctuations in the rate of exchange between the yen and the U.S. dollar can have a significant effect on the Company's reported financial position and results of operations. Aflac Japan's premiums and approximately half of its investment income are received in yen, and its claims and most expenses are paid in yen. Aflac Japan purchases yen-denominated assets and U.S. dollar-denominated assets, which may be hedged to yen, to support yen-denominated policy liabilities. These and other yen-denominated financial statement items are, however, translated into U.S. dollars for financial reporting purposes. Accordingly, fluctuations in the yen/dollar exchange rate can have a significant effect on the Company's reported financial position and results of operations. In periods when yen weakens, translating yen into U.S. dollars causes fewer U.S. dollars to be reported. When yen strengthens, translating yen into U.S. dollars causes more U.S. dollars to be reported. Any unrealized foreign currency translation adjustments are reported in accumulated other comprehensive income. As a result, yen weakening has the effect of suppressing current year results in relation to the prior year, while yen strengthening has the effect of magnifying current year results in relation to the prior year. In addition, the weakening of the yen relative to the U.S. dollar will generally adversely affect the value of the Company's yen-denominated investments in U.S. dollar terms.

Foreign currency translation also impacts the computation of the Company's risk-based capital ratio because Aflac Japan is consolidated in the Company's U.S. statutory filings due to its status as a branch. The Company's required capital, as determined by the application of risk factors to its assets and liabilities, is sensitive to currency risk. As a result, when the yen strengthens relative to the dollar, the Company's RBC is suppressed. The Company engages in certain foreign currency hedging activities for the purpose of hedging the yen exposure to its net investment in operations in Japan. These hedging activities are limited in scope, and the Company cannot provide assurance that these activities will be effective.

Unhedged U.S. dollar-denominated securities held by Aflac Japan are exposed to foreign exchange fluctuations, which impact SMR. In periods of yen strengthening, the unhedged U.S. dollar-denominated investments will experience unrealized foreign exchange losses, negatively impacting SMR. This impact increases when the size of the unhedged U.S. dollar-denominated portfolio increases, which can occur due to the purchase of additional unhedged U.S. dollar-denominated investments, or through termination or expiration of existing hedges. Unrealized currency gains and losses on unhedged U.S. dollar-denominated securities are monetized (or, in other words, are economically realized) only upon converting the proceeds from the sale, maturity or redemption of these securities to yen, which primarily occurs when yen are needed to satisfy policyholder obligations or other business expenses of Aflac Japan. To mitigate exposure to the foreign exchange risk from U.S. dollar-denominated investments and to reduce SMR volatility, the Company engages in certain currency hedging activities. However, these hedging activities are limited in scope and the Company cannot provide assurance that its hedging strategies will be effective. As a result, periods of unusually volatile currency exchange rates could result in limitations on dividends available to the Parent Company.

As indicated in the Business section of Item 1, the Company has determined that the unhedged U.S. dollar-denominated investment portfolio acts as a natural economic currency hedge of a portion of the Company’s investment in Aflac Japan against erosion of economic value. However, the unhedged U.S. dollar-denominated investment portfolio at the same time creates an unmatched foreign currency exposure and subjects Aflac Japan to volatility in regulatory capital and earnings, which may adversely impact Aflac Japan’s ability to pay dividends to the Parent Company. The overall investment strategy in Aflac Japan is guided primarily by the objective of securing the long-term financial strength of Aflac Japan and funding of yen liabilities. As a result, the Company has historically maintained and currently maintains the size of the unhedged portfolio at levels below the stressed economic surplus in Aflac Japan. However, there can be no assurance that this strategy will be successful.

Furthermore, for regulatory accounting purposes, there are certain requirements for realizing impairments that could be triggered by changes in the rate of exchange between the yen and U.S. dollar and could negatively impact Aflac Japan's earnings and the corresponding repatriation and capital deployment.

Additionally, the Company is exposed to currency risk when yen cash flows are converted into U.S. dollars, resulting in an increase or decrease in the Company's U.S. dollar-denominated cash flows and earnings when exchange gains or losses, respectively, are realized. This primarily occurs when the Company repatriates or dividends funds from Aflac Japan to the Parent Company, but it also has an impact when cash in the form of yen is converted to U.S. dollars for investment into U.S. dollar-denominated assets. The exchange rates prevailing at the time of repatriation or dividend may differ from the exchange rates prevailing at the time the yen profits were earned.

financial position or liquidity”. For more information regarding foreign currency risk, see the Currency Risk subsection within the Market Risks of Financial Instruments section of MD&A.


Lack of availability of acceptable yen-denominated investments could adversely affect the Company's results of operations, financial position or liquidity.
The Company attempts to match both the duration and currency of its assets with its liabilities. This is very difficult for Aflac Japan due to the lack of available long-dated yen-denominated fixed income instruments beyond JGBs.


Prior to the onset of the financial crisis of 2008, the Company was focused on investing cash flows in JGBs, which had relatively low yields, and utilizing private placement and perpetual securities to gain additional yield, extend the duration of the investment portfolio, and maintain yen exposure. Given call activity with respect to certain of the Company's legacy private placement investments, the Company has added a modest amount of yen-denominated private placements to its investment portfolio in recent periods. The investment in private placements and legacy perpetual securities carries risk associated with illiquidity, which is managed and monitored by the Company.


Starting in 2012, Aflac Japan augmented its investment strategy to include U.S. dollar-denominated investments, some of which could then be hedged back to yen. Initially this program focused on public investment-grade bonds but has evolved over time to include U.S. dollar-denominated investment-grade commercial mortgage loans, middle market loans, infrastructure debt, as well as other loan types, high yield bondsbond and U.S. equity securities. As of December 31, 2017, Aflac Japan held approximately $24.0 billion in U.S. dollar-denominated investments, at amortized cost. To hedge foreign currency risk, Aflac Japan held $9.3 billion outstanding notional amounts of foreign currency forwardspublic and $8.4 billion outstanding notional amounts of foreign currency options, of which none were in-the-money.private equities. The Company plans to continue adding other instruments denominated in U.S. dollars, including floating rate investments, to improve the portfolio diversification and/or return profile. Some of the U.S. dollar-denominated asset classes that the Company has added, and anticipates continuing to add, have less liquidity than investment-grade corporate bonds. These strategies will continue to increase the Company's exposure to U.S. interest rates, credit spreads and other risks. The Company has increased foreign exchange risk exposure as the comprehensive hedging program may not always correlate to the underlying U.S. dollar-denominated assets, thereby increasing earnings volatility. These risks can significantly impact the Company's consolidated results of operations, financial position or liquidity.

Investing in U.S. dollar-denominated investments in Aflac Japan also creates an unmatched foreign currency exposure and related SMR volatility, as Aflac Japan’s insurance liabilities are yen-denominated. Although the Company engages in certain foreign exchange hedging activities to partially mitigate this risk, and such hedged assets may be used to satisfy yen-denominated insurance liabilities and other business obligations, important risks remain.


Foreign exchange derivatives used for hedging are periodically settled, which results in cash receipt or payment at maturity or early termination. Cumulative net cash settlements on derivatives hedging currency exposure of Aflac Japan's U.S. dollar-denominated investments are associated with existing U.S. dollar-denominated investments that continue to be hedged, previously hedged investments that continue to be held but are no longer hedged, as well as, investments previously hedged that have since been sold, matured or redeemed and may or may not have not been converted to yen. The Company’s foreign exchange derivatives are typically shorter-dated than the underlying U.S. dollar-denominated investments being hedged.hedged, which creates roll-over risks within the hedging program that could increase the cost of such derivatives. If the Company reduces the notional amount of foreign exchange derivatives prior to the maturity of the hedged U.S. dollar-denominated investments, the respective holding foreign exchange gains or losses on the U.S. dollar-denominated investments remain economically unrealized. These foreign currency gains or losses on the investments are only economically realized, or monetized, through sale, maturity or redemption of the investments and concurrent conversion to yen. However, the Company may not realize the benefit of offsetting adverse cash settlements on hedging derivatives with cash receipts on the U.S. dollar-denominated investments if the currency exchange rates move in an adverse direction before the investments are converted to yen, or if the investments are never converted to yen. As an example of the latter, if the Company’s actual insurance risk experience in Japan is as expected or more favorable than expected, the need for yen to pay expenses and claims would correspondingly remain at or below expected levels, thereby diminishing operational requirements to convert U.S. dollar-denominated investments to yen. Since 2012, the cumulative net cash settlements on derivatives hedging currency exposure of Aflac Japan’s dollar-denominated investments were an outflow of $3.6 billion as of December 31, 2017. These outflows or cumulative net negative settlements are associated with foreign exchange derivatives on existing U.S. dollar-denominated investments and hedged investments that have since been sold, matured or redeemed and may or may have not been converted to yen. Furthermore, the settlements include instances where the initial foreign exchange derivative notional amounts were reduced prior to the maturity of the hedged investments. The settlement of the foreign exchange derivatives is reported in the investing activities section of the Company’s consolidated statements of cash flows in the line item “Settlement of derivatives, net.”

Quantitative and Qualitative Disclosures about Market Risk section in this report.

Failure to execute or implement the planned conversion of the Japan branch to a legal subsidiary could adversely affect the Company's business, results of operations, or financial position.

The implementation of the planned Japan branch conversion to a legal subsidiary is a complex undertaking and involves a number of risks, including increased execution costs, information technology-related delays and problems, personnel loss, regulatory law changes, legal and regulatory requirements, changes to the Company's operations, and management distraction. Changes in law or regulation before the completion of the transaction could result in significant costs or reduction in capital. The transaction may entail modifications of certain aspects of the Company's operations, which could result in additional costs or reduce net earnings. Any of these risks, if realized, could result in a material adverse effect on the Company's business, results of operations or financial condition.

The planned Japan branch conversion is conditioned on the continued validity of a private letter ruling that the Company received from the U.S. Internal Revenue Service (IRS). Notwithstanding the receipt of the private letter ruling, the IRS could determine that the Japan branch conversion should be treated as a taxable transaction. For example, the IRS could conclude that the representations, assumptions and covenants on which the private letter ruling is based are untrue or not accurate. If the IRS made such a conclusion, the Japan branch conversion could be treated as a taxable transaction, and the Company could incur significant U.S. federal income tax liabilities or litigation costs to defend the tax treatment by the IRS.

If future policy benefits, claims or expenses exceed those anticipated in establishing premiums and reserves, the Company's financial results would be adversely affected.

The Company establishes premiums for many of its policies on assumptions for morbidity, mortality, longevity and persistency. The Company also establishes and carries, as a liability, reserves based on estimates of how much will be required to pay for future benefits and claims on its policies. The Company calculates these reserves using various assumptions and estimates, including premiums the Company will receive over the assumed life of the policy; the timing, frequency and severity of the events covered by the insurance policy; and the investment returns on the assets the Company purchases with a portion of its net cash flow from operations.

The assumptions and estimates that the Company uses in establishing premiums and reserves depend on the Company's judgment regarding the likelihood of future events and are inherently uncertain. Many factors can cause actual outcomes to deviate from these assumptions and estimates, such as changes in economic conditions, changes in government healthcare policy, advances in medical technology, changes in treatment patterns, and changes in average lifespan. Accordingly, the Company cannot determine with precision the ultimate amounts that it will pay for, or the timing of payment of, actual benefits and claims or whether the assets supporting the policy liabilities will grow to the level the Company assumes prior to payment of benefits or claims. If the Company's actual experience is different from its assumptions or estimates, the Company's reserves may prove inadequate. As a result, the Company would incur a charge to earnings in the period in which it determines such a shortfall exists, which could have a material adverse effect on the Company's business, results of operations and financial condition.

Generally, lower mortality decreases the profitability of third sector products in Japan, as more policyholders will survive into ages where they have a higher rate of claim incidence. This assumption can impact pricing and reserving.  For instance, Japan FSA periodically requires updates to their Standard mortality tables for FSA reserves. An update to the Standard mortality tables will occur in April 2018 applicable to all business issued after that date. For business that is inforce prior to the update, the change in mortality table would not have an impact. For new issues, the updated mortality tables would be included in our reserve assumptions, and slow the emergence of FSA earnings for third sector products and therefore will have an impact on pricing returns. The Company adjusts pricing assumptions as new products are developed to adjust for these mortality assumptions. The Company is continuing to review potential impacts as it nears the adoption of those tables in April 2018.

The success of the Company's business depends in part on effective information technology systems and on continuing to develop and implement improvements in technology.

The Company's business depends in large part on its technology systems for interacting with employers, policyholders, sales associates, and brokers, and the Company's business strategy involves providing customers with easy-to-use products to meet their needs and ensuring employees have the technology in place to support those needs. Some of the Company's information technology systems and software are older, legacy-type systems that are less

19



efficient and require an ongoing commitment of significant resources to maintain or upgrade to current standards including adequate business continuity procedures. The Company is in a continual state of upgrading and enhancing its business systems; however, these changes tend to challenge the Company's complex integrated environment. The Company's success is dependent in large part on maintaining or improving the effectiveness of existing systems and continuing to develop and enhance information systems that support its business processes in a cost-efficient manner. If the Company does not maintain the effectiveness of its systems, the Company's operations and reputation could be adversely affected and it could be exposed to litigation as well as to regulatory proceedings and fines or penalties.

Competition could adversely affect the Company's ability to increase or maintain its market share or profitability.

The Company operates in a competitive environment and in an industry that is subject to ongoing changes from market pressures brought about by customer demands, legislative reform, marketing practices and changes to health care and health insurance delivery. These factors require the Company to anticipate market trends and make changes to differentiate the Company's products and services from those of its competitors. The Company also faces the potential of competition from existing or new companies in the United States and Japan that have not historically been active in the supplemental health insurance industry, but some of which have greater financial, marketing and management resources than the Company does. Failure to anticipate market trends and/or to differentiate the Company's products and services can affect the Company's ability to retain or grow profitable lines of business.

Further, as employers and brokers are increasingly requesting a full-suite of products from one insurance provider, a failure to react and adapt to these demands could result in decreased sales or market share. Similarly, a failure to meet evolving customer demands through innovative product development, effective distribution channels, and continuous investment in the Company's technology could result in lower revenues and less favorable policy terms and conditions, which could adversely affect the Company's operating results.

Events, including those external to the Company's operations, could damage the Company's reputation.
The Company has made significant investments in the Aflac brand over a long period of time. Because insurance products are intangible, the Company's ability to compete for and maintain policyholders relies to a large extent on consumer trust in the Company's business. The perception of unfavorable business practices or financial weakness could create doubt regarding the Company's ability to honor the commitments it has made to its policyholders. Maintaining the Company's stature as a trustworthy insurer and responsible corporate citizen, which helps support the strength of the Company's brand, is critical to the Company's reputation and the failure or perceived failure to do so could adversely affect the Company's brand value, financial condition and results of operations.

Sales of the Company's products and services are dependent on its ability to attract, retain and support a network of qualified sales associates, brokers and employees in the United States and sales associates and other distribution partners in Japan.

The Company's sales could be adversely affected if its sales networks deteriorate or if the Company does not adequately provide support, training and education for its existing network. In the United States, competition exists for sales associates and brokers with demonstrated ability. In Japan, the Company's sales results are dependent upon its relationship with sales associates and other distribution partners. The Company competes with other insurers and financial institutions primarily on the basis of its products, compensation, support services and financial rating. An inability to attract and retain qualified sales associates, brokers and other distribution partners, including its alliance partners in Japan, could have a material adverse effect on the Company's sales, results of operations and financial condition. The Company's sales associates and brokers are independent contractors and may sell products of its competitors. If the Company's competitors offer products that are more attractive, or pay higher commissions than the Company does, any or all of these distribution partners may concentrate their efforts on selling the Company's competitors' products instead of the Company's. In addition to the Company's commissioned sales force in the United States, Aflac has expanded its sales leadership team to include a salaried sales force of over 175 market directors and broker sales professionals. The Company's ability to attract and retain top talent in these salaried roles has a material impact on its sales success.

Additionally, as the Japan and U.S. employment markets continue to evolve, there is risk that the Company's practices regarding attracting, developing, and retaining employees may not be fully effective. Failure to successfully meet and maintain sufficient levels of employees may diminish the Company's ability to achieve its financial and compliance objectives, both of which are time consuming and personnel-intensive.

Interruption in telecommunication, information technology and other operational systems, or a failure to maintain the security, confidentiality, integrity or privacy of sensitive data residing on such systems, could harm the Company's business.

The Company stores confidential policyholder, employee, agent, and other proprietary information on its information technology systems. In addition, the Company depends heavily on its telecommunication, information technology and other operational systems and on the integrity and timeliness of data it uses to run its businesses and service its customers. These systems may fail to operate properly or become disabled as a result of events or circumstances wholly or partly beyond the Company's control. Despite the Company's implementation of a variety of security measures, its information technology and other systems, as well as those of third party providers, could be subject to physical or electronic break-ins, unauthorized tampering, security breaches or other cyber-attacks, resulting in a failure to maintain the security, confidentiality, integrity, or privacy of sensitive data, including personal information relating to customers, or in the misappropriation of the Company's intellectual property or proprietary information. Additionally, design flaws may exist in certain systems, processes, software, or configurations that in turn may result in system failure, data corruption, or compromise.

Although the minor data leakage issues the Company has experienced to date have not had a material effect on its business, there is no assurance that the Company's security systems or processes will prevent or mitigate future break-ins, tampering, security breaches or other cyber-attacks. Interruption in telecommunication, information technology and other operational systems, or a failure to maintain the security, confidentiality or privacy of sensitive data residing on such systems, whether due to actions by the Company or others, including third party providers, could delay or disrupt the Company's ability to do business and service its customers, seriously harm the Company's brand and reputation as well as the Company's ability to compete effectively, subject it to regulatory sanctions and other claims, lead to a loss of customers and revenues and otherwise adversely affect the Company's business. In addition, the costs to address or remediate system interruptions or security threats and vulnerabilities, whether before or after an incident, could be significant.

While the Company continues to invest in the infrastructure of its data security programs, the Company has been, and will likely continue to be, the target of unauthorized access, social engineering, phishing, cyber-attacks, web application attacks, computer viruses or other malicious codes, or other computer-related penetrations. Although the Company attempts to manage its exposure to such events through the purchase of cyber liability insurance, such events are inherently unpredictable and insurance may not be sufficient to protect the Company against all losses. As a result, events such as these could adversely affect the Company's financial condition or results of operation.


If the Company fails to comply with restrictions on customer privacy and information security, including taking steps to ensure that its third-party service providers and business associates who access, store, process or transmit sensitive customer information maintain its security, integrity, confidentiality and availability, the Company's reputation and business operations could be materially adversely affected.


The collection, maintenance, use, protection, disclosure and disposal of individually identifiable data by the Company's businesses are regulated at the international, federal and state levels. These laws and rules are subject to change by legislation or administrative or judicial interpretation. Various state laws address the unauthorized access and acquisition of personal information and the use and disclosure of individually identifiable health data to the extent they are more restrictive than those contained in the privacy and security provisions in the federal Gramm-Leach-Bliley Act of 1999 (GLBA)GLBA and in the Health Insurance Portability and Accountability Act of 1996 (HIPAA).HIPAA. HIPAA also requires that the Company imposes privacy and security requirements on its business associates (as such term is defined in the HIPAA regulations).With regard to personal information obtained from policyholders, the insured, or others, Aflac Japan is regulated in Japan by the Act on the Protection of Personal Information (APPI)APPI and guidelines issued by FSA and other governmental authorities.

The Company relies on third parties, and in some cases subcontractors, to provide information technology and data services. It also relies on various parties in its distribution channels including agencies, banks and Japan Post in Japan, as well as sales associates and brokers in the U.S., to provide services to prospective and existing customers. Although the Company provides for appropriate protections through its contracts and performs information security risk assessments of its third-party service providers and business associates, the Company still has limited control over their actions and practices. In addition, despite the security measures the Company has in place to ensure compliance with applicable laws and rules, the Company's facilities and systems, and those of the Company's third-party providers and participants in its distribution channels may be vulnerable to security breaches, acts of vandalism or theft, computer viruses, misplaced or lost data, programming and/or human errors or other similar events. From time to time, the Company, its third party providers and participants in the Company’s distribution channels have experienced and will likely continue to experience such events. In such cases, notification to affected individuals, state and federal regulators, state attorneys general and media may be required, depending upon the number of affected individuals and whether personal information including health or financial data was subject to unauthorized access.

The U.S. Congress and many states are considering new privacy and security requirements that would apply to the Company's business. Compliance with new privacy and security laws, requirements, and new regulations may result in cost

16



increases due to necessary systems changes, new limitations or constraints on the Company's business models, the development of new administrative processes, and the effects of

21



potential noncompliance by the Company's business associates. They also may impose further restrictions on the Company's collection, disclosure and use of customer identifiable data that are housed in one or more of the Company's administrative databases. Noncompliance with any privacy laws or any security breach involving the misappropriation, loss, theft or other unauthorized disclosure of sensitive or confidential customer information, whether by the Company or by one of its third parties, could have a material adverse effect on the Company's business, reputation, brand and results of operations, including: material fines and penalties; compensatory, special, punitive and statutory damages; consent orders regarding the Company's privacy and security practices; adverse actions against the Company's licenses to do business; and injunctive relief.

In addition, under Japanese laws and regulations, including the APPI, if a leak or loss of personal information by Aflac Japan or its business associates should occur, depending on factors such as the volume of personal data involved and the likelihood of other secondary damage, Aflac Japan may be required to file reports to the FSA; issue public releases explaining such incident to the public; or become subject to an FSA business improvement order, which could pose a risk to the Company's reputation.


Interruption in telecommunication, information technology and other operational systems, or a failure to maintain the security, confidentiality, integrity or privacy of sensitive data residing on such systems, could harm the Company's business.

The Company stores confidential policyholder, employee, agent, and other proprietary information on its information technology systems.

These systems may fail to operate properly or become disabled as a result of events or circumstances wholly or partly beyond the Company's control. Additionally, design flaws may exist in certain systems, processes, software, or configurations that in turn may result in system failure, data corruption, or compromise. Despite the Company's implementation of a variety of security measures to defend against threats incurred on a daily basis, its information technology and other systems, as well as those of third party providers and participants in the Company’s distribution channels, have been and will likely continue to be subject to physical or electronic break-ins, unauthorized tampering, security breaches or other cyber-attacks, that may result in the failure to adequately maintain the security, confidentiality, integrity, or privacy of sensitive data, including personal information relating to customers and prospective customers, or in the misappropriation of the Company's intellectual property or proprietary information.

From time to time, the Company, its third party providers and participants in the Company’s distribution channels have experienced and will likely continue to experience such events. Although the minor data leakage issues the Company has experienced to date have not had a material effect on its business, there is no assurance that the Company's security systems or processes will prevent or mitigate future break-ins, tampering, security breaches or other cyber-attacks. Interruption in telecommunication, information technology and other operational systems, or a failure to maintain the security, confidentiality or privacy of sensitive data residing on such systems, whether due to actions by the Company or others, including third party providers and participants in the company’s distribution channels, could delay or disrupt the Company's ability to do business and service its customers, seriously harm the Company's brand and reputation as well as the Company's ability to compete effectively, subject it to regulatory sanctions and other claims, lead to a loss of customers and revenues and otherwise adversely affect the Company's business.

Although the Company attempts to manage its exposure to such events through the purchase of cyber liability insurance, such events are inherently unpredictable and insurance may not be sufficient to protect the Company against all losses. As a result, events such as these could adversely affect the Company's financial condition or results of operation.

Catastrophic events could adversely affect the Company's financial condition and results of operations as well as the availability of the Company’s infrastructure and systems.

The Company's insurance operations are exposed to the risk of catastrophic events including, but not necessarily limited to, epidemics, pandemics, tornadoes, hurricanes, earthquakes, tsunamis, war or other military action, and terrorism or other acts of violence. The extent of losses from a catastrophe is a function of both the total amount of insured exposure in the area affected by the event and the severity of the event. Certain events such as earthquakes, tsunamis, hurricanes and man-made catastrophes could cause substantial damage or loss of life in larger areas, especially those that are heavily populated. Claims resulting from natural or man−made catastrophic events could cause substantial volatility in the Company's financial results for any fiscal quarter or year and could materially reduce its profitability or harm the Company's financial condition, as well as affect its ability to write new business.

Additionally, the Company's business operations may be adversely affected by such catastrophic events to the extent they disrupt the Company's physical infrastructure, human resources or systems that support its businesses and customers. Although the Company has a global crisis management framework to minimize the business disruption from a catastrophic event, such framework may not be effective to avoid an adverse impact to the Company from such an event.

Difficult conditions in global capital markets and the economy could have a material adverse effect on the Company's investments, capital position, revenue, profitability, and liquidity and harm the Company's business.
The Company's results of operations are materially affected by conditions in the global capital markets and the global economy generally, including in its two primary operating markets of the U.S. and Japan. Weak global financial markets impact the value of the Company's existing investment portfolio, influence opportunities for new investments, and may contribute to generally weak economic fundamentals, which can have a negative impact on its operating activities.

In recent years, global capital markets have been severely impacted by several major events. The financial crisis that began in the latter part of 2008 saw dramatic declines in investment values and weak economic conditions as the global financial system came under extreme pressure. Although U.S. markets began recovering in late 2009 and 2010, Europe continued to struggle under a severely weakened banking system and investor concerns with sovereign debt levels. Following a period of unprecedented intervention by governments and central banks, including the U.S. Federal Reserve and European Central Bank (ECB), financial conditions improved from the dire conditions of the global financial crisis, global recession, and European debt crisis. More recently, global markets have experienced bouts of volatility due to uncertainty surrounding a British exit from the European Union, Japan’s continued recovery amidst assorted policy changes, volatility in global commodity prices including oil, divergent monetary policies in the U.S. versus many other developed economies, heightened concerns surrounding the Chinese economy and increasing protectionism in U.S. foreign trade policy. While capital and market conditions have been generally favorable in the last year, the prospect for increased volatility remains.

A shift in the global trading policies by the U.S. and subsequent trade conflict with China has raised concerns about a slowdown of the Chinese economy and the recent trade agreement between the U.S. and China left tariffs in place and many trade issues unresolved. In addition, the recent trade agreement between the U.S. and Japan resulted in tariff reductions on some products but left tariffs on other products in place. While it is not expected that the Company's products would be directly impacted by tariffs, any resulting economic downturn could adversely affect the Company.

Activity by the government of North Korea in 2018 was the subject of increasing focus for a number of other governments, including those of the U.S. and Japan. Although hostile rhetoric decreased in 2019, there is a possibility of renewed hostility between their governments. In addition, in January 2020, hostility between the government of the U.S. and the government of Iran increased, ultimately culminating in a number of missile strikes. Such activity and related geopolitical risk could have a significant impact on financial market conditions across the world. Under certain circumstances, government actions taken in response to these or similar situations could have a material impact on the Company's operations and financial performance, including the indirect impact of potentially severe and prolonged capital market volatility and disruption.

As the Company holds a significant amount of fixed maturity securities issued by borrowers located in many different parts of the world, including a large portion issued by banks and financial institutions, sovereigns, and other corporate borrowers in the U.S. and Europe, its financial results are directly influenced by global financial markets. A retrenchment of the recent strength of the capital markets could adversely affect the Company's financial condition, including its capital position and overall profitability. Market volatility and recessionary pressures could result in significant realized or unrealized losses due to severe price declines driven by increases in interest rates or credit spreads, defaults in payment of principal or interest, or credit rating downgrades.

Following the election of Shinzo Abe as Prime Minister of Japan in December 2012, the new administration adopted a new set of financial measures to stimulate the Japanese economy, including imposing negative interest rates on excess bank reserves. In December 2014 and October 2017 snap-elections, the ruling Liberal Democratic Party (LDP) won decisive victories further strengthening Mr. Abe's ability to continue with economic reforms and address key policy challenges. In September 2018, Mr. Abe won reelection to another three-year term as president of the LDP. Most recently, the BoJ signaled to hold its policy rate at zero and to continue yield curve control to maintain a targeted yield on the 10-year JGB. Prime Minister Abe’s election victories may result in the continuation of current monetary policy, but there can be no guarantee that this is the case.

Japan is the largest market for the Company's products, and the Company owns substantial holdings in JGBs. Government actions to stimulate the economy affect the value of the Company's existing holdings, its reinvestment rate on new investments in JGBs or other yen-denominated assets, and consumer behavior relative to the Company's suite of products. The additional government debt from fiscal stimulus actions could adversely impact the Japan sovereign credit profile, which could in turn lead to volatility in Japanese capital and currency markets.

The Company's investment portfolio has sizeable credit positions in many other geographic areas of the world including the Middle East, Latin America, Asia, and other emerging markets. Deterioration in their underlying economies, sovereign credit worthiness, or financial market conditions could negatively impact the Company's financial position.

While the Company has continued to add floating rate investments to its investment portfolio, most of its investment portfolio holdings are income-producing bonds that provide a fixed level of income. Many of the Company's investments were made at the relatively low level of interest rates prevailing over the last decade. Any increase in the market yields of the Company's holdings due to an increase in interest rates could create substantial unrealized losses in the Company's portfolio, as discussed further in a separate risk factor in this section of the Form 10-K.

The Company needs liquidity to pay its operating expenses, dividends on its common stock, interest on its debt, and liabilities. For a further description of the Company's liquidity needs, including maturing indebtedness, see the Liquidity and Capital Resources section of MD&A in this report. In the event the Company's current resources do not meet its needs, the Company may need to seek additional financing. The Company's access to additional funding will depend on a variety of factors such as market conditions, the general availability of credit to the financial services industry and its credit rating.

Should investors become concerned with any of the Company's investment holdings, including the concentration in JGBs, its access to market sources of funding could be negatively impacted. There is a possibility that lenders or debt investors may also become concerned if the Company incurs large investment losses or if the level of the Company's business activity decreases due to a market downturn or there are further adverse economic trends in the U.S. or Japan, specifically, or generally in developed markets. Similarly, the Company's access to funds may be impaired if regulatory authorities or rating agencies take negative actions. See more information on recent rating actions later in this Risk Factors section.

Broad economic factors such as consumer spending, business investment, government spending, the volatility and strength of the capital markets, and inflation all affect the business and economic environment and, indirectly, the amount and profitability of the Company's business. In an economic downturn characterized by higher unemployment, lower family income, lower corporate earnings, lower business investment and lower consumer spending, the demand for financial and insurance products could be adversely affected. This adverse effect could be particularly significant for companies such as Aflac that distribute supplemental, discretionary insurance products primarily through the worksite in the event that economic conditions result in a decrease in the number of new hires and total employees. Adverse changes in the economy could potentially lead the Company's customers to be less inclined to purchase supplemental insurance coverage or to decide to cancel or modify existing insurance coverage, which could adversely affect the Company's premium revenue, results of operations and financial condition. The Company is unable to predict the course of the global financial markets or the recurrence, duration or severity of disruptions in such markets.

Events, including those external to the Company's operations, could damage the Company's reputation.

The Company has made significant investments in the Aflac brand over a long period of time. Because insurance products are intangible, the Company's ability to compete for and maintain policyholders relies to a large extent on consumer trust in the Company's business, including its alliance partners, sales associates and other distribution partners. The perception of unfavorable business practices or financial weakness with respect to the Company, its alliance partners, sales associates or other distribution partners could create doubt regarding the Company's ability to honor the commitments it has made to its policyholders. Such a perception could also negatively impact the Company’s ability to attract and retain qualified sales associates, brokers and other distribution partners, including its alliance partners in Japan, and could have a material adverse effect on the Company's sales, results of operations and financial condition. Maintaining the Company's stature as a trustworthy

19



insurer and responsible corporate citizen, which helps support the strength of the Company's brand, is critical to the Company's reputation and the failure or perceived failure to do so could adversely affect the Company's brand value, financial condition and results of operations. For example, negative publicity or allegations of unfavorable business practices or poor governance can be rapidly and widely shared over social or traditional media or other means, and could reduce demand for the Company's insurance products, reduce the Company's ability to recruit and retain employees, or lead to greater regulatory scrutiny of the Company's operations.

Extensive regulation and changes in legislation can impact profitability and growth.


Aflac's insurance subsidiaries are subject to complex laws and regulations that are administered and enforced by a number of governmental authorities, including the FSA and Ministry of Finance (MOF) in Japan, and state insurance regulators, the SEC, the NAIC, the FIO, the U.S. Department of Justice, state attorneys general, the U.S. Commodity Futures Trading Commission, and the U.S. Treasury, including the IRS,Internal Revenue Service (IRS), in the United States,U.S., each of which exercises a degree of interpretive latitude. In addition, proposals regarding the global regulation of insurance are under discussion, and changes to corporate form that attend the conversion of Aflac Japan to a subsidiary may introduce new forms of regulation compared to those with which the Company has historically been subject. For example, AAMJ is licensed as a discretionary asset manager under the Japan Financial Instruments and Exchange Act and is subject to rules of the Japan Investment Advisors Association, a self-regulatory organization with mandatory membership for Japan investment managers. Consequently, the Company is subject to the risk that compliance with any particular regulator's or enforcement authority's interpretation of a legal or regulatory issue may not result in compliance with another regulator's or enforcement authority's interpretation of the same issue, particularly when compliance is judged in hindsight. There is also a risk that any particular regulator's or enforcement authority's interpretation of a legal or regulatory issue may change over time to the Company's detriment. In addition, changes in the overall legal or regulatory environment may, even absent any particular regulator's or enforcement authority's interpretation of an issue changing, cause us to change the Company's views regarding the actions the Company needs to take from a legal or regulatory risk management perspective, thus necessitating changes to the Company's practices that may, in some cases, limit its ability to grow or otherwise negatively impact the profitability of the Company's business.


The primary purpose of insurance company regulatory supervision is the protection of insurance policyholders, rather than investors. The extent of regulation varies, but generally is governed by state statutes in the United StatesU.S. and by the FSA and the MOF in Japan. These systems of supervision and regulation cover, among other things:


standards of establishing and setting premium rates and the approval thereof
standards of minimum capital and reserve requirements and solvency margins, including risk-based capitalRBC measures
restrictions on, limitations on and required approval of certain transactions between the Company's insurance subsidiaries and their affiliates, including management fee arrangements
restrictions on the nature, quality and concentration of investments
restrictions on the types of terms and conditions that the Company can include in the insurance policies offered by its primary insurance operations
limitations on the amount of dividends that insurance subsidiaries can pay or foreign profits that can be repatriated
the existence and licensing status of a company under circumstances where it is not writing new or renewal business
certain required methods of accounting
reserves for unearned premiums, losses and other purposes
assignment of residual market business and potential assessments for the provision of funds necessary for the settlement of covered claims under certain policies provided by impaired, insolvent or failed insurance companies
administrative practices requirements
imposition of fines and other sanctions

22



Regulatory authorities periodically re-examine existing laws and regulations applicable to insurance companies and their products. Changes in these laws and regulations, or in interpretations thereof, could have a material adverse effect on the Company's financial condition and results of operations. If the Company's subsidiaries fail to meet the minimum capital or operational requirements established by its respective regulators, they could be subject to examination or corrective action, or the Company's financial strength ratings could be downgraded, or both.

Various forms of federal oversight and regulation of insurance were signed into law by the prior U.S. presidential administration. For example, the ACA gave the U.S. federal government direct regulatory authority over the business of health insurance and made significant changes to the U.S. health care insurance marketplace, including the imposition of an individual medical insurance coverage mandate (which has since been repealed effective 2019 by the Tax Act), penalties on certain employers for failing to provide adequate coverage, the creation of health insurance exchanges, and proscriptions regarding coverage and exclusions as well as medical loss ratios. The legislation also includes changes in government reimbursements and tax credits for individuals and employers and alters federal and state regulation of health insurers. The ACA, as enacted, does not require material changes in the design of the Company's insurance products. However, indirect consequences of the legislation and regulations could present challenges that could potentially have an impact on the Company's sales model, financial condition and results of operations. The United States Congress has considered and may continue to consider legislation that would repeal and replace key provisions of the ACA. There can be no assurance that any legislation affecting the ACA will be passed by Congress, nor as to the ultimate timing or provisions of any such legislation, nor as to the effect of any such legislation on the design or marketability of the Company's insurance products.

In addition, the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 (“Dodd Frank”), intended to reduce risk of a financial crisis, contains multiple provisions that could impact the Company's business as rules are finalized and implemented. While it is difficult to isolate the impact of Dodd Frank from other government and central bank actions and general market conditions since the financial crisis, the Company believes that the Dodd-Frank Act, in particular bank capital requirements, limits on proprietary trading and derivatives regulation, has affected the value of its holdings in banks and other financial institutions, and impacted pricing, liquidity, and the Company's general ability to conduct financial and capital market transactions. Dodd Frank is expansive in scope and, among other things, requires the adoption of extensive regulations and numerous regulating decisions, many of which have been adopted. The presidential administration in the United States and Congress have stated proposals to reform or repeal certain provisions of the Dodd-Frank Act, some of which have been implemented. The Company cannot predict with any degree of certainty the ultimate effects (if any) that Dodd Frank, or subsequent implementation of regulations and decisions, will have on its U.S. business, financial condition, or results of operations.


Compliance with applicable laws and regulations is time consuming and personnel-intensive, and changes in these laws and regulations may materially increase the Company's direct and indirect compliance and other expenses of doing business, thus having a material adverse effect on the Company's financial condition and results of operations.

The Companyis exposed to foreign currency fluctuations in the yen/dollar exchange rate.

Due to the size of Aflac Japan, where functional currency is the Japanese yen, fluctuations in the rate of exchange between the yen and the U.S. dollar can have a significant effect on the Company's reported financial position and results of operations. Aflac Japan's premiums and approximately half of its investment income are received in yen, and its claims and most expenses are paid in yen. Aflac Japan purchases yen-denominated assets and U.S. dollar-denominated assets, which may be hedged to yen, to support yen-denominated policy liabilities. These and other yen-denominated financial statement items are, however, translated into U.S. dollars for financial reporting purposes. Accordingly, fluctuations in the yen/dollar exchange rate can have a significant effect on the Company's reported financial position and results of operations. In periods when yen weakens, translating yen into U.S. dollars causes fewer U.S. dollars to be reported. When yen strengthens, translating yen into U.S. dollars causes more U.S. dollars to be reported. Any unrealized foreign currency translation adjustments are reported in accumulated other comprehensive income. As a result, yen weakening has the effect of suppressing current year results in relation to the prior year, while yen strengthening has the effect of magnifying current year results in relation to the prior year. In addition, the weakening of the yen relative to the U.S. dollar will generally adversely affect the value of the Company's yen-denominated investments in U.S. dollar terms.

The Company engages in certain foreign currency hedging activities for the purpose of hedging the yen exposure to its net investment in operations in Japan. These hedging activities are limited in scope, and the Company cannot provide assurance that these activities will be effective.

Unhedged U.S. dollar-denominated securities held by Aflac Japan are exposed to foreign exchange fluctuations, which impact SMR. In periods of yen strengthening, the unhedged U.S. dollar-denominated investments will experience unrealized foreign exchange losses, negatively impacting SMR. This impact increases when the size of the unhedged U.S. dollar-denominated portfolio increases, which can occur due to the purchase of additional unhedged U.S. dollar-denominated investments, or through termination or expiration of existing hedges. Unrealized currency gains and losses on unhedged U.S. dollar-denominated securities are monetized (or, in other words, are economically realized) only upon converting the proceeds from the sale, maturity or redemption of these securities to yen, which primarily occurs when yen are needed to satisfy policyholder obligations or other business expenses of Aflac Japan. To mitigate exposure to the foreign exchange risk from U.S. dollar-denominated investments and to reduce SMR volatility, the Company engages in certain currency hedging activities. However, these hedging activities are limited in scope and the Company cannot provide assurance that its hedging strategies will be effective. As a result, periods of unusually volatile currency exchange rates could result in limitations on dividends available to the Parent Company.

As indicated in the MD&A, the Company has determined that the unhedged U.S. dollar-denominated investment portfolio acts as a natural economic currency hedge of a portion of the Company’s investment in Aflac Japan against erosion of economic value. However, the unhedged U.S. dollar-denominated investment portfolio at the same time creates an unmatched foreign currency exposure and subjects Aflac Japan to volatility in regulatory capital and earnings, which may adversely impact Aflac Japan’s ability to pay dividends to the Parent Company. The overall investment strategy in Aflac Japan is guided primarily by the objective of securing the long-term financial strength of Aflac Japan and funding of yen liabilities. As a result, the Company has historically maintained and currently maintains the size of the unhedged portfolio at levels below the economic equity surplus in Aflac Japan. However, there can be no assurance that this strategy will be successful.

Furthermore, for regulatory accounting purposes, there are certain requirements for realizing impairments that could be triggered by changes in the rate of exchange between the yen and U.S. dollar and could negatively impact Aflac Japan's earnings and the corresponding dividends and capital deployment.

Additionally, the Company is exposed to currency risk when yen cash flows are converted into U.S. dollars, resulting in an increase or decrease in the Company's U.S. dollar-denominated cash flows and earnings when exchange gains or losses, respectively, are realized. This primarily occurs when the Company dividends funds from Aflac Japan to the Parent Company, but it also has an impact when cash in the form of yen is converted to U.S. dollars for investment into U.S. dollar-denominated assets. The exchange rates prevailing at the time of dividend payment may differ from the exchange rates prevailing at the time the yen profits were earned. In 2018, the Parent Company began entering into forward contracts to accomplish a dual objective of hedging foreign currency exchange rate risk related to dividend payments by Aflac Japan, and reducing enterprise-wide hedge costs. If the markets experience a significant strengthening of yen, this could cause cash strain at the Parent Company as a result of cash collateral and potentially cash settlement requirements. Based on the timing and severity of exchange rate fluctuations combined with the level of outstanding activity in this program, the cash strain at the Parent Company could be significant. 

For more information regarding unhedged U.S. dollar-denominated securities, see the risk factor below entitled, “Lack of availability of acceptable yen-denominated investments could adversely affect the Company’s results of operations, financial

21



position or liquidity”. For more information regarding foreign currency risk, see the Currency Risk subsection within the Market Risks of Financial Instruments section of MD&A.

Tax rates applicable to the Company may change.


The Company is subject to taxation in Japan, and in the U.S. under federal and numerous state and local tax jurisdictions. In preparing the Company's financial statements, the Company estimates the amount of tax that will become payable, but the Company's effective tax rate may be different than estimates due to numerous factors including accounting for income taxes, the mix of earnings from Japan and the U.S., the results of tax audits, adjustments to the value of uncertain tax positions, changes to estimates and other factors. Further, changes in U.S. or Japan tax laws or interpretations of such laws could increase the Company's corporate taxes and reduce earnings.

Among other changes, effective January 1, 2018 the Tax Act reduced the U.S. federal statutory corporate income tax rate from 35% to 21%, eliminated or reduced certain deductions and credits, and limited the deductibility of interest expense and executive compensation. The Tax Act also transitions international corporate taxation from a worldwide system to a modified territorial system, which in light of the current tax treatment of Aflac Japan as a branch has the effect of subjecting the earnings of Aflac Japan to Japan taxation and subjecting the Company's other earnings, including the consolidated earnings of the Parent Company, to U.S. taxation. The changes to tax law included in the Tax Act are complex and are subject to new and changing regulations, interpretations and tax guidance in the future, as well as further refinement of our estimates and calculations and changes in the interpretations and assumptions that the Company has made. As such, the Company's estimates based upon the changes in the Tax Act may change over time. For example, during the period ended December 31, 2017, the Company revalued its deferred tax assets and liabilities and recorded, as its current reasonable estimate, a net deferred tax liability reduction of $1.9 billion as of that date. While the Company believes that this estimate is reasonable, it is relying upon guidance provided by SEC Staff Accounting Bulletin No. 118 (SAB 118) that provides a measurement period of up to one year from the enactment date of December 22, 2017, in order

23



to complete the accounting for the effects of the Tax Act. Therefore, in future periods the Company may reduce or increase the estimated reduction of net deferred tax liability, and any such revision may be material.


In addition, it remains difficult to predict the timing and effect that future tax law changes could have on the Company's earnings both in the U.S. and in foreign jurisdictions. Any of these factors could cause the Company to experience an effective tax rate significantly different from previous periods or ourthe Company's current estimates. If the Company's effective tax rate were to increase, the Company's financial condition and results of operations could be adversely affected.

Defaults, downgrades, widening credit spreads or other events impairing the value of the fixed maturity securities, perpetual securities and loan receivables in the Company's investment portfolio may reduce the Company's earnings and capital position.
The Company is subject to the risk that the issuers and/or guarantors of fixed-maturity securities, perpetual securities and loan receivables the Company owns may default on principal or interest. A significant portion of the Company's portfolio represents an unsecured obligation of the issuer, including some that may be subordinated to other debt in the issuer’s capital structure. In these cases, many factors can influence the overall creditworthiness of the issuer and ultimately its ability to service and repay the Company's holdings. This can include changes in the global economy, the company's assets, strategy, or management, shifts in the dynamics of the industries in which they compete, their access to additional funding, and the overall health of the credit markets. Factors unique to the Company's securities including contractual protections such as financial covenants or relative position in the issuer's capital structure also influence the value of the Company's holdings.

Most of the Company's investments carry a rating by one or more of the NRSROs. Any change in the rating agencies' approach to evaluating credit and assigning an opinion could negatively impact the fair value of the Company's portfolio. The Company employs a team of credit analysts to monitor the creditworthiness of the issuers in its portfolio. Any credit-related declines in the fair value of positions held in the Company's portfolio believed to be not temporary in nature will negatively impact the Company's net income and capital position through impairment and other credit related losses. These losses would also affect the Company's solvency ratios in the United States and Japan. Aflac Japan has certain regulatory accounting requirements for realizing impairments that could be triggered by credit-related losses, which may be different from U.S. GAAP and statutory requirements. These impairment losses could negatively impact Aflac Japan's earnings, and the corresponding repatriation and capital deployment.

The Company is also subject to the risk that any collateral providing credit enhancement to the Company's positions could deteriorate. These instruments may include senior secured first lien loans, such as commercial mortgage loans, bank loans, middle market loans, and loan-backed securities where the underlying loan or collateral notes may default on principal, interest, or other payments, causing an adverse change in cash flows to the positions held in the Company's investment portfolio.

The Company's portfolio includes holdings of perpetual securities. Most of these are issued by global banks and financial institutions. Following the financial crisis, rating agencies reviewed and, in most cases, modified the rating criteria for financial institutions. This has caused multiple downgrades of many bank and financial issuers, but perpetual securities have been more negatively impacted as their lower position in the capital structure represents relatively more risk than other more senior obligations of the issuer. Further downgrades or default of issuers of securities the Company owns will have a negative impact on its portfolio and could reduce the Company's earnings and capital.

The Company is exposed to sovereign credit risk through instruments issued directly by governments and government entities as well as banks and other institutions that rely in part on the strength of the underlying government for their credit quality. In addition to the United States and Japan, many governments, especially in Europe, have been subject to rating downgrades due to the need for fiscal and budgetary remediation and structural reforms, reduced economic activity, and investment needed to support banks or other systemically important entities. Additional downgrades or default of the Company's sovereign issuers will have a negative impact on its portfolio and could reduce the Company's earnings and capital.

In addition to the Company's exposure to the underlying fundamental credit strength of the issuers of its fixed maturity and perpetual securities and the underlying risk of default, the Company is also exposed to the general movement in credit market spreads. A widening of credit spreads could reduce the value of the Company's existing portfolio, create unrealized losses on its investment portfolio, and reduce the Company's adjusted capital position which is used in determining the SMR in Japan. This widening of credit spreads could, however, increase the net investment income on new credit investments. Conversely, a tightening of credit spreads could increase the value of the Company's existing portfolio and create unrealized gains on its investment portfolio. This tightening of credit spreads could also reduce the net

24



investment income available to the Company on new credit investments. Increased market volatility also makes it difficult to value certain of the Company's investment holdings (see the Critical Accounting Estimates section in Item 7, Management's Discussion and Analysis, of this Form 10-K).

For more information regarding credit risk, see the Credit Risk subsection of Item 7A, Quantitative and Qualitative Disclosures about Market Risk, of this Form 10-K.


A decline in the creditworthiness of other financial institutions could adversely affect the Company.


The Company has exposure to and routinely executes transactions with counterparties in the financial services industry, including broker dealers, derivative counterparties, commercial banks and other institutions.


The Company uses derivative instruments to mitigate various risks associated with its investment portfolio, notes payable, and profit repatriation.subsidiary dividends. The Company enters into a variety of agreements involving assorted instruments including foreign currency forward contracts,contracts; foreign currency options; and foreign currency swaps; and interest rate swaps. To provide additional alternatives to increase the Company's overall portfolio yield while managing its overall currency risk, starting in 2012, the Company invested a significant portion of the investable cash flow generated by Aflac Japan into U.S. dollar-denominated investmentsswaps and hedged these investments to yen through the use of currency forward and option contracts. The derivative forward and option contracts are of a shorter maturity than the hedged investments, which creates roll-over risks within the hedging program. Due to changes in market environments, there is a risk the hedges become ineffective and lose the corresponding hedge accounting treatment. At December 31, 2017, the Company held foreign currency forwards and options of approximately $9.3 billion of notional amount associated with Aflac Japan's U.S. dollar-denominated investments referenced above; foreign currency swaps of $2.8 billion of notional amount associated with the Company's notes payable; and foreign currency forwards and options of approximately $439 million of notional amount used to economically hedge profit repatriation.swaptions. The Company's increased use of derivatives has increased itsresults in financial exposure to derivative counterparties. If the Company's counterparties fail or refuse to honor their obligations under derivative instruments, the Company's hedges of the risks will be ineffective, and the Company's financial condition and results of operations could be adversely affected.


The Company engages in derivative transactions directly with unaffiliated third parties under International Swaps and Derivatives Association, Inc. (ISDA) agreements and other documentation. Most of the ISDA agreements also include Credit Support Annexes (CSAs) provisions, which generally provide for two-way collateral postings at the first dollar of exposure. The Company mitigates the risk that counterparties to transactions might be unable to fulfill their contractual obligations by monitoring counterparty credit exposure and collateral value while generally requiring that collateral be posted at the outset of the transaction. In addition, a significant portion of the derivative transactions have provisions that give the counterparty the right to terminate the transaction upon a downgrade of Aflac’s financial strength rating. The actual amount of payments that the Company could be required to make, depends on market conditions, the fair value of outstanding affected transactions, and other factors prevailing at and after the time of the downgrade. If the Company is required to post collateral to support derivative contracts and/or pay cash to settle the contracts at maturity, the Company's liquidity could be strained. In addition, the Company's cleared swaps result in counterparty exposure to clearing brokers and central clearinghouses; while this exposure is mitigated in part by clearinghouse and clearing broker capital and regulation, no assurance can be provided that these counterparties will fulfill their obligations. The Company also has exposure to counterparties to securities lending transactions in the event they fail to return loaned securities. The Company is also exposed to the risk that there may be a decline in value of securities posted as collateral for securities lending programs or a decline in value of investments made with cash posted as collateral for such programs.


Further, the Company has agreements with various financial institutions for the distribution of its insurance products. For example, at December 31, 2017,2019, the Company had agreements with 374367 banks to market Aflac's products in Japan. Sales through these banks represented 5.2%4.3% of Aflac Japan's new annualized premium sales in 2017.2019. Any material adverse effect on these or other financial institutions could also have an adverse effect on the Company's sales.
The Company has entered into significant reinsurance transactions with large, highly rated counterparties. Negative events or developments affecting any one of these counterparties could have an adverse effect on the Company's financial position or results of operations.
All of these risks related to exposure to other financial institutions could adversely impact the Company's consolidated results of operations and financial condition.



22



The determination of the amount of impairments taken on the Company's investments is based on significant valuation judgments and could materially impact its results of operations or financial position.
An investment in a fixed maturity security is impaired if the fair value falls below book value. The Company regularly reviews its entire investment portfolio for declines in value. The majority of the Company's investments are evaluated for other-than-temporary impairment using the Company's debt impairment model.
The Company's debt impairment model includes emphasis on the ultimate collection of the cash flows from its investments. The determination of the amount of impairments under this model is based upon the Company's periodic evaluation and assessment of known and inherent risks associated with the respective securities. Such evaluations and assessments are revised as conditions change and new information becomes available.
For the Company's fixed maturity securities reported in the available-for-sale portfolio, the Company reports the investments at fair value in the statement of financial condition and records any unrealized gain or loss in the value of the asset in accumulated other comprehensive income. For the Company's held-to-maturity securities portfolio, the Company reports the investments at amortized cost. Under the debt impairment model, the determination of whether an impairment in value is other than temporary is based largely on the Company's evaluation of the issuer's creditworthiness. The Company must apply considerable judgment in determining the likelihood of the security recovering in value while the Company owns it. Factors that may influence this include the Company's assessment of the issuer’s ability to continue making timely payments of interest and principal, the overall level of interest rates and credit spreads, and other factors. The Company also verifies whether it has the intent to sell or if it is more likely than not the Company would be required to sell the security prior to recovery of its amortized cost. If the Company determines it is unlikely to recover the book value of the instrument prior to disposal of the security, the Company will reduce the carrying value of the security to its fair value and recognize any associated impairment loss in the Company's consolidated statement of earnings or other comprehensive income, depending on the nature of the loss.
For regulatory accounting purposes for Aflac Japan, there are certain requirements for realizing impairments that could be triggered by rising interest rates, credit-related losses, or changes in foreign exchange, negatively impacting Aflac Japan's earnings and corresponding dividend and capital deployment.
The Company's management updates its evaluations regularly as conditions change and as new information becomes available and reflects impairment losses in the Company's income statement when considered necessary. Furthermore, additional impairments may need to be taken in the future. Historical trends may not be indicative of future impairments.

U.S. tax audit risk related to conversion of the Japan branch to a subsidiary could adversely impact the Company's financial position.

The conversion of the Japan branch to a legal subsidiary, which the Company executed in the second quarter of 2018, was a complex, tax-free transaction that is conditioned on the continued validity of a private letter ruling the Company received from the IRS. Notwithstanding the receipt of the private letter ruling, the IRS could determine that the Japan branch conversion should be treated as a taxable transaction. For example, the IRS could conclude that the representations, assumptions and covenants on which the private letter ruling is based are untrue, not accurate, or have not been fulfilled. If the IRS made such a conclusion, the Company could incur significant U.S. federal income tax liabilities or litigation costs to defend the tax-free treatment of the transaction outlined by the private letter ruling. Such liabilities or costs could have a material adverse effect on the Company's business, results of operations and financial condition.

As a holding company, the Parent Company depends on the ability of its subsidiaries to transfer funds to it to meet its debt service and other obligations and to pay dividends on its common stock.
The Parent Company is a holding company and has no direct operations, and its most significant assets are the stock of its subsidiaries. Because the Parent Company conducts its operations through its operating subsidiaries, the Parent Company depends on those entities for dividends and other payments to generate the funds necessary to meet its debt service and other obligations, and to pay dividends on and conduct repurchases of its common stock.

25



stock, and to make investments into its subsidiaries or external investment opportunities.
Aflac is domiciled in Nebraska and is subject to insurance regulations that impose certain limitations and restrictions on payments of dividends, management fees, loans and advances by Aflac to the Parent Company. The Nebraska insurance statutes require prior approval for dividend distributions that exceed the greater of the net income from operations, which excludes net realized investment gains, for the previous year determined under statutory accounting principles, or 10% of statutory capital and surplus as of the previous year-end. In addition, the Nebraska insurance department must approve

23



service arrangements and other transactions within the affiliated group of companies. After the planned Japan branch conversion, the Company expects that the Nebraska insurance department and the FSA will approveapproved their respective domiciled insurance company service arrangements and transactions. The FSA maydoes not allow profit repatriationsdividends or other transferspayments from Aflac Japan if they would cause Aflac Japan to lack sufficient financial strength for the protection of Japanese policyholders. After the planned Japan branch conversion as early as April 1, 2018, the new Japan subsidiary will be required to meetunless it meets certain financial criteria as governed by Japanese corporate law in order to provide dividends to the Parent Company.law. Under these criteria, dividend capacity at the Japan subsidiary will be defined as retained earnings plus other capital reserve less net after-tax net unrealized losses on available-for-sale securities.
The ability of Aflac and Aflac Japan (in its current form as a branch, and in its planned future form as a subsidiary) to pay dividends or make other payments to the Parent Company could also be constrained by the Company's dependency on financial strength ratings from independent rating agencies. The Company's ratings from these agencies depend to a large extent on Aflac's capitalization level. Any inability of Aflac to pay dividends or make other payments to the Parent Company could have a material adverse effect on the Company's financial condition and results of operations.
For the foregoing reasons, there is no assurance that the earnings from, or other available assets of, the Parent Company's operating subsidiaries will be sufficient to make distributions to enable the Company to operate.
Any decrease in the Company's financial strength or debt ratings may have an adverse effect on its competitive position and access to liquidity and capital.


Financial strength ratings can play an important role in establishing the competitive position of insurance companies. On an ongoing basis, NRSROs review the financial performance and condition of many insurers, including Aflacthe Company and its competitors. They may assign multiple ratings including a financial strength rating, reflecting their view of the insurer’s ability to pay claims on a timely basis, and ratings on an insurer’s senior and subordinated debt obligations, indicating their view of an insurer’s ability to make timely payments on their debt obligations.


NRSROs may change their ratings or outlook on an insurer's ratings due to a variety of factors including the NRSRO’s assessment of the insurer’s strength of operations and overall financial condition. Some factors that may influence ratings include competitive position; profitability; cash generation and other sources of liquidity; capital levels; quality of the investment portfolio; and perception of management capabilities. The ratings assigned to Aflacthe Company by the NRSROs are important factors in the Company's ability to access liquidity and capital from the bank market, debt capital markets or other available sources, such as reinsurance transactions. Downgrades to Aflac'sthe Company's credit ratings could give its derivative counterparties the right to require early termination of derivatives transactions or delivery of additional collateral, thereby adversely affecting the Company's liquidity.


In view of the difficulties experienced after the financial crisis by many financial institutions, including those in the insurance industry, the NRSROs have heightened the level of scrutiny that they apply to such institutions. Steps taken by the NRSROs include an increase in the frequency and scope of their reviews, additional information requests from the companies that they rate, including additional information regarding the valuation of investment securities held, and, in certain cases, an increase in the capital and other requirements employed in their models for maintenance of certain rating levels.


On September 16, 2015, S&P downgraded their credit rating of Japan’s sovereign debt. Following this action, they also downgraded several other foreign insurers, including Aflac. Although Aflac is a U.S.-based insurer, Aflac'sthe Company. The Company's significant operations in Japan and corresponding regulation by the Japanese FSA, combined with its significant exposure to JGBs as outlined above, resulted in S&P downgrading the financial strength rating of Aflac's core insurance operations to A+ and itsthe Parent Company's senior debt rating to A-, both with a stable outlook. While S&P made no further downgrades to Aflac'sthe Company's ratings inbetween 2016 or 2017,and 2019, they have stated in the paststate that a downgrade of Japan's sovereign rating could lead to a downgrade of Aflac'sthe Company's financial strength rating. As a matter of policy, S&P rarely rates insurance companies above the sovereign long-term rating of the country of domicile because during times of stress, the sovereign’s regulatory and supervisory powers may restrict an insurer’s or financial system’s flexibility. Moody’s has also stated that the following factors could lead to a downgrade of the Company’s ratings: a downgrade of the U.S. or Japanese operating entities; or a downgrade of the Government of Japan sovereign debt rating.


26




In addition to the impact on Aflac'sthe Company's access to liquidity, as mentioned above, a downgrade of Aflac'sthe Company's ratings could have a material adverse effect on agent recruiting and retention, sales, competitiveness and the marketability of its products which could negatively impact Aflac'sthe Company's liquidity, operating results and financial condition. Additionally, sales through the bank channel in Japan could be adversely affected as a result of their reliance and sensitivity to ratings levels.



24



The Company cannot predict what actions rating agencies may take, or what actions the Company may take in response to the actions of rating agencies, which could adversely affect Aflac'sthe Company's business. As with other companies in the financial services industry, Aflac'sthe Company's ratings could be downgraded at any time and without any notice by any NRSRO.


The Company's risk management policies and procedures may prove to be ineffective and leave the Company exposed to unidentified or unanticipated risk, which could adversely affect the Company's businesses or result in losses.


The Company has developed an enterprise-wide risk management and governance framework to mitigate risk and loss to the Company. The Company maintains policies, procedures and controls intended to identify, measure, monitor, report and analyze the risks to which the Company is exposed.
However, there are inherent limitations to risk management strategies because risk may exist, or emerge in the future, that the Company has not appropriately anticipated or identified. If the Company's risk management framework proves ineffective, the Company may suffer unexpected losses and could be materially adversely affected. As the Company's businesses change and the markets in which it operates evolve, the Company's risk management framework may not evolve at the same pace as those changes. As a result, there is a risk that new products or new business strategies may present risks that are not appropriately identified, monitored or managed. In times of market stress, unanticipated market movements or unanticipated claims experience resulting from greater than expected morbidity, mortality, longevity, or persistency, the effectiveness of the Company's risk management strategies may be limited, resulting in losses to the Company. In addition, under difficult or less liquid market conditions, the Company's risk management strategies may not be effective because other market participants may be using the same or similar strategies to manage risk under the same challenging market conditions. In such circumstances, it may be difficult or more expensive for the Company to mitigate risk due to the activity of such other market participants.
Many of the Company's risk management strategies or techniques are based upon historical customer and market behavior and all such strategies and techniques are based to some degree on management’s subjective judgment. The Company cannot provide assurance that its risk management framework, including the underlying assumptions or strategies, will be accurate and effective.
Management of operational, legal and regulatory risks requires, among other things, policies, procedures and controls to record properly and verify a large number of transactions and events, and these policies, procedures and controls may not be fully effective. Models are utilized by the Company's businesses and corporate areas primarily to project future cash flows associated with pricing products, calculating reserves and valuing assets, as well as in evaluating risk and determining capital requirements, among other uses. These models are utilized under a risk management policy approved by the Company's executive risk management committees, however, the models may not operate properly and rely on assumptions and projections that are inherently uncertain. As the Company's businesses continue to grow and evolve, the number and complexity of models the Company utilizes expands, increasing the Company's exposure to error in the design, implementation or use of models, including the associated input data and assumptions.
Past or future misconduct by the Company's employees or employees of the Company's third parties (suppliers which are cost-based relationships and alliance partners which are revenue-generating relationships) could result in violations of law by the Company, regulatory sanctions and/or serious reputational or financial harm and the precautions the Company takes to prevent and detect this activity may not be effective in all cases. Despite the Company's published Supplier Code of Conduct, due diligence of the Company's alliance partners, and rigorous contracting procedures (including financial, legal, IT security, and risk reviews), there can be no assurance that controls and procedures that the Company employs, which are designed to assess third party viability and prevent the Company from taking excessive or inappropriate risks, will be effective. Additionally, the use of third parties also poses operational risks that could result in financial loss, operational disruption, brand damage, or compliance issues. Inadequate oversight of Aflac’s third party suppliers due to the lack of policies, procedures, training and governance may lead to financial loss or damage to the Aflac brand.

27



The concentration of the Company's investment portfolios in any particular single-issuer or sector of the economy may have an adverse effect on the Company's financial position or results of operations.
Negative events or developments affecting any particular single issuer, industry, group of related industries, asset class or geographic sector may have an adverse impact on a particular holding or set of holdings, which may increase risk of loss from defaults due to non-payment of interest or principal. The Company seeks to minimize this risk by maintaining an appropriate level of diversification. To the extent the Company has concentrated positions, it could have an adverse effect on the Company's results of operations and financial position. The Company's global investment guidelines establish

concentration limits for its investment portfolios.


At December 31, 2017, the Company held approximately $48.4 billion at amortized cost, or 45.4% of its total debt and perpetual securities, in JGBs. JGBs were rated A1/A+/A at December 31, 2017 by Moody's, S&P and Fitch, respectively. For further details on the concentrations within the Company's investment portfolios, see the Analysis of Financial ConditionInvestments section of Item 7, MD&A, and the Credit Risk section of Item 7A, Quantitative and Qualitative Disclosures about Market Risk, of this Form 10-K.


The valuation of the Company's investments and derivatives includes methodologies, estimations and assumptions which are subject to differing interpretations and could result in changes to investment valuations that may adversely affect the Company's results of operations or financial condition.
The Company reports a significant amount of its fixed maturity securities and other financial instruments at fair value. As such, valuations may include inputs and assumptions that are less observable or require greater estimation as well as valuation methods which are more sophisticated, thereby resulting in values which may be greater or less than the value at which the investments may be ultimately sold. Rapidly changing and unprecedented credit and equity market conditions could materially impact the valuation of securities as reported within the Company's consolidated financial statements and the period-to-period changes in value could vary significantly.


Valuations of the Company's derivatives fluctuate with changes in underlying market variables, such as interest rates and foreign currency exchange rates. During periods of market turbulence created by political instability, economic uncertainty, government interventions or other factors, the Company may experience significant changes in the volatility of its derivative valuations. Extreme market conditions can also affect the liquidity of such instruments creating marked differences in transaction levels and counterparty valuations. Depending on the severity and direction of the movements in its derivative valuations, the Company will face increases in the amount of collateral required to be posted with its counterparties. Liquidity stresses to the Company may also occur if the required collateral amounts increase significantly over a very short period of time. Conversely, the Company may be exposed to an increase in counterparty credit risk for short periods of time while calling collateral from its counterparties.


Elimination of LIBOR as an interest rate benchmark may create uncertainty in valuation of loans, derivatives and other assets where valuation and interest rates are based on LIBOR, and may create uncertainty in the pricing of such assets in markets for their sale and disposition.

For further discussion on investment and derivative valuations, see the Critical Accounting Estimates section in Item 7, Management's Discussion and Analysis, and Notes 1, 3, 4, and 5 of the Notes to the Consolidated Financial Statements in this Form 10-K.

Managing key executive succession is critical to the Company's success.
The Company would be adversely affected if it fails to adequately plan for successiondepends heavily on key management personnel, and the loss of services of one or more of its senior management and other key executives. While the Company has succession plans and employment arrangements with certain key executives these plans cannot guarantee thatcould harm the Company's business.

The Company’s success depends to a significant extent upon the efforts and abilities of its key management personnel. The loss of the services of theseone or more of the Company's senior executives will be available tocould significantly undermine its management expertise and the Company, and its operationsCompany's business could be adversely affected if they are not.affected.

The determination of the amount of impairments taken on the Company's investments is based on significant valuation judgments and could materially impact its results of operations or financial position.
An investment in a fixed maturity, perpetual or equity security is impaired if the fair value falls below book value. The Company regularly reviews its entire investment portfolio for declines in value. The majority of the Company's investments are evaluated for other-than-temporary impairment using the Company's debt impairment model, while the Company's investments in equities and below-investment-grade perpetual securities are evaluated using the Company's equity impairment model.
The Company's debt impairment model includes emphasis on the ultimate collection of the cash flows from its investments. The determination of the amount of impairments under this model is based upon the Company's periodic

28



evaluation and assessment of known and inherent risks associated with the respective securities. Such evaluations and assessments are revised as conditions change and new information becomes available.
For the Company's fixed maturity and perpetual securities reported in the available-for-sale portfolio, the Company reports the investments at fair value in the statement of financial condition and records any unrealized gain or loss in the value of the asset in accumulated other comprehensive income. For the Company's held-to-maturity securities portfolio, the Company reports the investments at amortized cost. Under the debt impairment model, the determination of whether an impairment in value is other than temporary is based largely on the Company's evaluation of the issuer's creditworthiness. The Company must apply considerable judgment in determining the likelihood of the security recovering in value while the Company owns it. Factors that may influence this include the Company's assessment of the issuer’s ability to continue making timely payments of interest and principal, the overall level of interest rates and credit spreads, and other factors. The Company also verifies whether it has the intent to sell or if it is more likely than not the Company would be required to sell the security prior to recovery of its amortized cost. If the Company determines it is unlikely to recover the book value of the instrument prior to disposal of the security, the Company will reduce the carrying value of the security to its fair value and recognize any associated impairment loss in the Company's consolidated statement of earnings or other comprehensive income, depending on the nature of the loss.
The Company's investments in perpetual securities that are rated below investment grade and equity securities are evaluated for other-than-temporary impairment under the Company's equity impairment model. This impairment model focuses on the severity of a security's decline in fair value coupled with the length of time the fair value of the security has been below cost or amortized cost and the financial condition and near-term prospects of the issuer. For equity securities, the Company also verifies its intent to hold the securities until they recover in value.
For regulatory accounting purposes for Aflac Japan, there are certain requirements for realizing impairments that could be triggered by rising interest rates, credit-related losses, or changes in foreign exchange, negatively impacting Aflac Japan's earnings and corresponding repatriation and capital deployment.
The Company's management updates its evaluations regularly as conditions change and as new information becomes available and reflects impairment losses in the Company's income statement when considered necessary. Furthermore, additional impairments may need to be taken in the future. Historical trends may not be indicative of future impairments.

Catastrophic events could adversely affect the Company's financial condition and results of operations as well as the availability of the Company’s infrastructure and systems.

The Company's insurance operations are exposed to the risk of catastrophic events including, but not necessarily limited to, epidemics, pandemics, tornadoes, hurricanes, earthquakes, tsunamis, war or other military action, and terrorism or other acts of violence. The extent of losses from a catastrophe is a function of both the total amount of insured exposure in the area affected by the event and the severity of the event. Certain events such as earthquakes, tsunamis, hurricanes and man-made catastrophes could cause substantial damage or loss of life in larger areas, especially those that are heavily populated. Claims resulting from natural or man−made catastrophic events could cause substantial volatility in the Company's financial results for any fiscal quarter or year and could materially reduce its profitability or harm the Company's financial condition, as well as affect its ability to write new business.

Additionally, the Company's business operations may be adversely affected by such catastrophic events to the extent they disrupt the Company's physical infrastructure and systems that support its businesses and customers.


Changes in accounting standards issued by the Financial Accounting Standard Boards (FASB) or other standard-setting bodies may adversely affect the Company's financial statements.
The Company's financial statements are subject to the application of generally accepted accounting principles in both the United States and Japan,U.S. GAAP, which areis periodically revised and/or expanded. Accordingly, from time to time the Company is required to adopt new or revised accounting standards issued by recognized authoritative bodies, including the FASB. It is possibleThe impact of accounting pronouncements that future accounting standardshave been issued but not yet implemented and are applicable to the Company is requireddisclosed in Note 1 of the Notes to adopt couldthe Consolidated Financial Statements. The pronouncements expected to have the most significant impact on the Company's financial position or results of operations are outlined below.
In June 2016, the FASB issued Accounting Standard Update (ASU) 2016-13, Financial Instruments - Credit Losses: Measurement of Credit Losses on Financial Instruments. The amendments in this update require a financial asset (or a group of financial assets) measured on an amortized cost basis to be presented net of an allowance for current expected credit losses in order to reflect the amount expected to be collected on the financial asset(s). The Company currently estimates the after-tax net impact from the adoption of ASU 2016-13 at a $56 million decrease to retained earnings, which primarily relates to loans and loan receivables. The amendments are effective for fiscal years beginning after December 15, 2019.

26



Additionally, in August 2018 the FASB issued ASU 2018-12, Financial Services - Insurance, Targeted Improvements to the Accounting for Long-Duration Contracts. The amendments in this update will significantly change how insurers account for long-duration contracts. Among the current accounting treatmentissues addressed in the amendments is the requirement to review and, if there is a change, update cash flow assumptions for the liability for future policy benefits at least annually, and to update the discount rate assumption quarterly. The Company anticipates that the Company appliesrequirement to review and update assumptions for liability for future policy benefits will have a significant impact on its consolidated financial statementsresults of operations, systems, processes, and that such changescontrols, while the requirement to update the discount rate will have a significant impact on the other comprehensive income component of its equity. The amendments are effective for fiscal years beginning after December 15, 2021. See Critical Accounting Estimates section of Item 7. MD&A in this report.

Changes to accounting standards could have a material adverse effect on the Company's results of operations and financial condition. During the last three years, various accounting standard-setting bodies have been active in soliciting comments and issuing statements, interpretations and exposure drafts. For information on new accounting pronouncements and the impact, if any, on the Company's financial position or results of operations, see Note 1 of the Notes to the Consolidated Financial Statements in this report.

29



Changes in the Company's discount rate, expected rate of return, life expectancy, health care cost and expected compensation increase assumptions for its pension and other postretirement benefit plans may result in increased expenses and reduce the Company's profitability.

The Company determines its pension and other postretirement benefit plan costs based on assumed discount rates, expected rates of return on plan assets, life expectancy of plan participants and expected increases in compensation levels and trends in health care costs. Changes in these assumptions, including from the impact of a sustained low interest rate environment, may result in increased expenses and reduce the Company's profitability.

The Company faces risks related to litigation.litigation, regulatory investigations and inquiry and other matters.


The Company is a defendant in various lawsuits considered to be in the normal course of business. Members of the Company's senior legal and financial management teams review litigation on a quarterly and annual basis. The final results of any litigation cannot be predicted with certainty.certainty, and plaintiffs may seek very large amounts in class actions or other litigation. Although some of this litigation is pending in states where large punitive damages, bearing little relation to the actual damages sustained by plaintiffs, have been awarded in recent years, the Company believes the outcome of pending litigation will not have a material adverse effect on its financial position, results of operations, or cash flows. However, litigation could adversely affecta substantial legal liability or a significant federal, state or other regulatory action against the Company, because ofas well as regulatory inquiries or investigations, could harm the Company's reputation, result in changes in operations, result in material fines or penalties, result in significant costs of defending these cases, costs of settlementdue to legal fees, settlements or judgments against the Company, or becauseotherwise have a material adverse effect on the Company's business, financial condition and results of operations. Without limiting the foregoing, the litigation and regulatory matters the Company is, has been, or may become, subject to include matters related to sales agent recruiting, policy sales practices, claim payments and procedures including denial or delay of benefits, material misstatements or omissions in the Company's financial reports or other public statements, and/or corporate governance, corporate culture or business ethics matters. Further, the Company may be subject to claims of or litigation regarding sexual or other forms of misconduct or harassment, or discrimination on the basis of race, color, national origin, religion, gender, or other bases, notwithstanding that the Company's Code of Business Conduct and Ethics prohibits such harassment and discrimination by its employees, the Company has ongoing training programs and provide opportunities to report claims of noncompliant conduct, and it investigates and may take disciplinary action regarding alleged harassment or discrimination. Any violations of or deviation from laws, regulations, internal or external codes or standards of normative behavior, or perceptions of such violations or deviations, by the Company's employees or by independent sales agents could adversely impact the Company's reputation and brand value, financial condition and results of operations.

Allegations or determinations of agent misclassification could adversely affect the Company’s results of operations, financial condition and liquidity.

A majority of the Company's U.S. sales force is, and has historically been, comprised of independent agents. While the Company believes that it has properly classified such agents as independent contractors, the Company may be subject to claims, regulatory action by state or federal departments of labor or tax authorities or litigation asserting that such agents are employees. The laws and regulations governing the classification of workers in the U.S. may be changed or interpreted differently compared to past interpretations, including in states where the Company generates significant sales through independent agents. An allegation or determination that independent agents in the Company’s U.S. sales force have been misclassified as independent contractors could result in changes in itsthe Company’s operations that couldand U.S. business model, result from litigation.in material fines or penalties, result in significant costs due to legal fees, settlements or judgments against the Company, or otherwise have a material adverse effect on the Company's business, results of operation, financial condition and liquidity.

ITEM 3. LEGAL PROCEEDINGS

On December 14, 2017, three former independent sales contractors filed a shareholders derivative complaint in the U.S. District Court for the Southern District of New York naming the Parent Company as nominal defendant and the Parent Company’s Chairman and Chief Executive Officer, several of its directors, and a former officer and director as defendants. The complaint alleges breaches of fiduciary duty, misstatements and omissions in the Company’s public disclosures, and insider trading. The Company’s Board of Directors had previously established a special litigation committee (SLC) in July 2017 to investigate certain allegations underlying the derivative action. The SLC issued a report of its investigation in September 2017 and another report in February 2018, each of which determined that it was not in the best interests of the Company to pursue the action demanded by the shareholders. On February 12, 2018, this litigation was transferred to the U.S. District Court for the Middle District of Georgia. The Company intends to file a motion to dismiss based upon the conclusions of the special committee in these two reports. An amended complaint was filed on January 31, 2018, and the SLC is investigating certain additional allegations raised in the new filing. The Company believes the outcome of this litigation will not have a material adverse effect on its financial position, results of operation or cash flows.

On February 9, 2018, a putative class action complaint was filed in the U.S. District Court for the Middle District of Georgia, purportedly on behalf of purchasers of Aflac Incorporated stock between February 27, 2013 and January 11, 2018. The complaint names the Parent Company and certain officers as defendants and alleges the Company’s public disclosures were misleading in relation to purported recruiting practices, misclassification of independent contractors, manipulation of a sales

30




metric, and failure to adhere to the Company’s Code of Business Conduct and Ethics and corporate social responsibility standards. The complaint seeks class action certification, an unspecified amount for compensatory damages and interest, costs and expenses, and other unspecified equitable or injunctive relief. The Company believes that this lawsuit is without merit. The Company intends to vigorously defend against the allegations made in the complaint and to file a motion to dismiss the action.


The Company is a defendant in various lawsuits considered to be in the normal course of business. Members of the Company's senior legal and financial management teams review litigation on a quarterly and annual basis. The final results of any litigation cannot be predicted with certainty. Although some of this litigation is pending in states where large punitive damages, bearing little relation to the actual damages sustained by plaintiffs, have been awarded in recent years, the Company believes the outcome of pending litigation will not have a material adverse effect on its financial position, results of operations, or cash flows.

THE COMPANY'S BUSINESS2020 OUTLOOK


The Company’s strategy to drive long-term shareholder value is to pursue growth through product development, distribution expansion and digital advancements to improve the customer experience.

The Company's objectives in 2020 are to maintain strong pre-tax margins in its Aflac Japan and Aflac U.S. segments through disciplined product pricing, stable investment returns and leveraging a period of favorable benefit ratios to invest in its platform for future growth and efficiency. The Company believes that its market-leading position, powerful brand recognition and diverse distribution in Japan and the U.S. will provide support toward these objectives.

The Company believes that its efforts will support its prudent strategies for capital deployment in the form of dividends, share repurchases, and opportunistic investments that enhance the Company’s business with a focus on digital distribution and leveraging the Company’s brand, distribution and scale. The Company has stated that the dividend payout ratio from its Aflac Japan segment is likely to be to 100% of FSA earnings from Aflac Japan and 100% of U.S. statutory earnings from Aflac U.S. In its Aflac U.S. segment, the Company plans to maintain a risk-based capital (RBC) ratio in the 500% range for 2020.

Aflac Incorporated (the Parent Company)Japan Segment
In Japan, the Company anticipates that the shift in earned premium from first sector savings products to third sector cancer and its subsidiaries (collectively, the Company) primarily sell supplemental healthmedical products and life insurancefirst sector protection products, will continue to result in moderately lower benefit ratios in the United StatesAflac Japan segment. The Company also expects this shift in business mix, plus continued investment in IT and digital advancements, to result in moderately higher expense ratios for Aflac Japan. The Company's insurance business is marketedCompany anticipates the Japan segment will face revenue challenges in 2020 due to the run-off and administered through American Family Life Assurancepaid-up status of first sector savings and third sector products. The Company of Columbus (Aflac), which operatesexpects a decline in the United States (Aflac U.S.)range of .7% in third sector and first sector protection earned premium for 2020. In addition, net investment income is expected to decline modestly as compared to 2019, due in part to the low interest rate environment in Japan and de-risking of the portfolio, partially offset by lower hedge cost as a branchresult of a reduction in Japan (Aflac Japan). American Family Life Assurance Companythe hedge ratio in the fourth quarter of New York (Aflac New York) is a wholly owned subsidiary of Aflac.

The Company expects Aflac U.S. to generate earned premium growth in the range of 1% in 2020. Net investment income is expected to decline modestly, primarily as the result of the Company’s implemented U.S. capital and RBC draw-down plan.


Corporate and Other Segment
The Company expects corporate segment results to benefit from net investment income driven by increased capital and liquidity held at the Parent Company, as well as the increase in size of the Company’s enterprise currency hedging strategy. The anticipated increase in investment income is expected to be partially offset by increased costs associated with continued investment in Aflac Corporate Ventures initiatives.

For more informationimportant disclosures applicable to statements made in this 2020 Outlook, please see the Risk Factors section and the statement on Forward-Looking Information at the Company's business, seebeginning of Item 1. Business, Part I,the Risk Factors identified in Item 1 of this report.1A. and Item 7. Management Discussion and Analysis.


PERFORMANCE HIGHLIGHTSRESULTS OF OPERATIONS


Yen-denominatedThe Company earns its revenues principally from insurance premiums and investments. The Company’s operating expenses primarily consist of insurance benefits provided and reserves established for anticipated future insurance benefits, general business expenses, commissions and other costs of selling and servicing its products. Profitability for the Company depends principally on its ability to price its insurance products at a level that enables the Company to earn a margin over the costs associated with providing benefits and administering those products. Profitability also depends on, among other items, actuarial and policyholder behavior experience on insurance products, and the Company's ability to attract and retain customer assets, generate and maintain favorable investment results, effectively deploy capital and utilize tax capacity, and manage expenses.

Yen–denominated income statement accounts are translated to U.S. dollars using a weighted-averageweighted average Japanese yen/U.S. dollar foreign exchange rate, while yen-denominatedexcept realized gains and losses on security transactions which are translated at the exchange rate on the trade date of each transaction. Yen–denominated balance sheet accounts are translated to U.S. dollars using a spot Japanese yen/U.S. dollar foreign exchange rate.

The following discussion includes references to the Company's performance measures, adjusted earnings, adjusted earnings per diluted share, and amortized hedge costs/income, which are not calculated in accordance with U.S. GAAP (non-U.S. GAAP). These measures exclude items that the Company believes may obscure the underlying fundamentals and trends in the Company's insurance operations because they tend to be driven by general economic conditions and events or related to infrequent activities not directly associated with its insurance operations. The Company's management uses adjusted earnings and adjusted earnings per diluted share to evaluate the financial performance of its insurance operations on a consolidated basis, and the Company believes that a presentation of these measures is vitally important to an understanding of its underlying profitability drivers and trends of its insurance business. The Company believes that amortized hedge costs/income, which are a component of adjusted earnings, measure the periodic currency risk management costs/income related to hedging certain foreign currency exchange risks and are an important component of net investment income.

The Company defines the non-U.S. GAAP financial measures included in this filing as follows:

Adjusted earnings are the profits derived from operations.The most comparable U.S. GAAP measure is net earnings. Adjusted earnings are adjusted revenues less benefits and adjusted expenses. The adjustments to both revenues and expenses account for certain items that cannot be predicted or that are outside management’s control. Adjusted revenues are U.S. GAAP total revenues excluding realized investment gains and losses, except for amortized hedge costs/income related to foreign currency exposure management strategies and net interest cash flows from derivatives associated with certain investment strategies. Adjusted expenses are U.S. GAAP total acquisition and operating expenses including the impact of interest cash flows from derivatives associated with notes payable but excluding any nonrecurring or other items not associated with the normal course of the Company’s insurance operations and that do not reflect the Company's underlying business performance.

Adjusted earnings per share (basic or diluted) are adjusted earnings for the period divided by the weighted average outstanding shares (basic or diluted) for the period presented. The most comparable U.S. GAAP measure is net earnings per share.

Amortized hedge costs/income represent costs/income incurred or recognized in using foreign currency forward
contracts to hedge certain foreign exchange risks in the Company's Japan segment (costs) or in the Corporate and Other segment (income). These amortized hedge costs/income are derived from the difference between the foreign currency spot yen/dollar exchange rate at December 31, 2017 was 113.00, or 3.1% stronger thantime of trade inception and the spot yen/dollar exchangecontractual foreign currency forward rate, recognized on a straight line basis over the term of 116.49 at December 31, 2016. The weighted-averagethe hedge. There is no comparable U.S. GAAP financial measure for amortized hedge costs/income.

Adjusted earnings and adjusted earnings per diluted share excluding current period foreign currency impact are computed using the average yen/dollar exchange rate for the comparable prior year ended December 31, 2017 was 112.16, or 3.1% weaker thanperiod, which eliminates fluctuations driven solely by yen-to-dollar currency rate changes.


37


Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations

Amounts excluding foreign currency impact on U.S. dollar-denominated investment income were determined using the weighted-averageaverage dollar/yen exchange rate for the comparable prior year period.

Adjusted book value is the U.S. GAAP book value (representing total shareholders' equity), less AOCI as recorded on the U.S. GAAP balance sheet. The Company considers adjusted book value important as it excludes AOCI, which fluctuates due to market movements that are outside management's control.

Adjusted return on equity (ROE) excluding foreign currency impact is calculated using adjusted earnings excluding the impact of the yen/dollar exchange rate, as reconciled with total U.S. GAAP net earnings, divided by average shareholders’ equity, excluding AOCI. The most comparable U.S. GAAP financial measure is return on average equity as determined using net earnings and average total shareholders’ equity.

The following table is a reconciliation of 108.70 for the same period in 2016.

Total revenues decreased 4.0% to $21.7 billion in 2017, compared with $22.6 billion in 2016. Netitems impacting adjusted earnings in 2017 were $4.6 billion, or $11.54and adjusted earnings per diluted share compared with $2.7 billion, or $6.42to the most directly comparable U.S. GAAP measures of net earnings and net earnings per diluted share, respectively, for the years ended December 31.

Reconciling Items

Realized Investment Gains and Losses

The Company's investment strategy is to invest primarily in fixed maturity securities to provide a reliable stream of investment income, which is one of the drivers of the Company’s growth and profitability. This investment strategy incorporates asset-liability matching (ALM) to align the expected cash flows of the portfolio to the needs of the Company's liability structure. The Company does not purchase securities with the intent of generating capital gains or losses. However, investment gains and losses may be realized as a result of changes in the U.S. Tax Act.financial markets and the creditworthiness of specific issuers, tax planning strategies, and/or general portfolio management and rebalancing. The realization of investment gains and losses is independent of the underwriting and administration of the Company's insurance products. Realized investment gains and

Impairments include other-than-temporary-impairment losses on investment securities as well as changes in loan loss reserves for loan receivables. Starting in the first quarter of 2018, gains and losses from changes in fair value of equity securities are recorded in earnings.
Certain Derivative and Foreign Currency Gains (Losses)

The Company's derivative activities include foreign currency forwards and options on certain fixed maturity securities; foreign currency forwards and options that economically hedge certain portions of forecasted cash flows denominated in yen and hedge the Company's long-term exposure to a weakening yen; foreign currency swaps associated with certain senior notes and subordinated debentures; foreign currency swaps and credit defaults swaps held in consolidated variable interest entities (VIEs); interest rate swaps used to economically hedge interest rate fluctuations in certain variable-rate investments; and interest rate swaptions to hedge changes in the fair value associated with interest rate changes for certain dollar-denominated available-for-sale securities. Gains and losses are recognized as a result of valuing these derivatives, net of the effects of hedge accounting. The Company also excludes the accounting impacts of remeasurement associated with changes in the yen/dollar exchange rate from adjusted earnings. Amortized hedge costs/ income related to certain foreign currency exposure management strategies (see Amortized Hedge Cost/Income section below), and net interest cash flows from derivatives associated with certain investment strategies and notes payable are reclassified from realized investment gains (losses). and included in adjusted earnings.


Amortized hedge costs/income can fluctuate based upon many factors, including the derivative notional amount, the length of time of the derivative contract, changes in both U.S. and Japan interest rates, and supply and demand for dollar funding. Amortized hedge costs and income have fluctuated in recent periods due to changes in the previously mentioned factors. For additional information regarding foreign currency hedging, refer to Hedging Activities in the Investments section of this MD&A.

For additional information regarding realized investment gains and losses, including details of reported amounts for the periods presented, see Notes 3 and 4 of the Notes to the Consolidated Financial Statements.

Other and Non-recurring Items

The U.S. insurance industry has a policyholder protection system that provides funds for the policyholders of insolvent insurers. The system can result in periodic charges to the Company as a result of insolvencies/bankruptcies that occur with other companies in the life insurance industry. Some states permit member insurers to recover assessments paid through full or partial premium tax offsets. These charges neither relate to the ordinary course of the Company’s business nor reflect the Company’s underlying business performance, but result from external situations not controlled by the Company. The Company excludes any charges associated with U.S. guaranty fund assessments and the corresponding tax benefit or expense from adjusted earnings.

In October 2017,Japan, the government also requires the insurance industry to contribute to a policyholder protection corporation that provides funds for the policyholders of insolvent insurers; however, these costs are calculated and administered differently than in the U.S. In Japan, these costs are not directly related to specific insolvencies or bankruptcies, but are rather a regular operational cost for an insurance company. Based on this structure, the Company does not remove the Japan policyholder protection expenses from adjusted earnings.

Nonrecurring items also include conversion costs related to legally converting the Company's Japan business to a subsidiary; these costs primarily consist of expenditures for legal, accounting, consulting, integration of systems and processes and other similar services. These Japan branch conversion costs were an immaterial amount for the year-ended December 31, 2019 and $75 million for the year-ended December 31, 2018.

Income Taxes

The Company's combined U.S. and Japanese effective income tax rate on pretax earnings was 25.7% in 2019 and 26.7% in 2018. The decrease in the U.S. federal statutory corporate income tax rate from 35% to 21% effective January 1, 2018 drove the reduction in the effective tax rate for 2019 and 2018. Total income taxes were $1.1 billion in both 2019 and 2018. Japanese income taxes on Aflac Japan's results account for most of the Company's consolidated income tax expense.

For further information, see "Critical Accounting Estimates - Income Taxes" in this MD&A, and Note 10 of the Notes to the Consolidated Financial Statements for additional information.

Foreign Currency Translation

Aflac Japan’s premiums and a significant portion of its investment income are received in yen, and its claims and most expenses are paid in yen. Aflac Japan purchases yen-denominated assets and U.S. dollar-denominated assets, which may be hedged to yen, to support yen-denominated policy liabilities. These and other yen-denominated financial statement items are, however, translated into dollars for financial reporting purposes. The Company translates Aflac Japan’s yen-denominated income statement into dollars using the average exchange rate for the reporting period, and the Company translates its yen-denominated balance sheet using the exchange rate at the end of the period.

Due to the size of Aflac Japan, whose functional currency is the Japanese yen, fluctuations in the yen/dollar exchange rate can have a significant effect on the Company's reported results. In periods when the yen weakens, translating yen into dollars results in fewer dollars being reported. When the yen strengthens, translating yen into dollars results in more dollars being reported. Consequently, yen weakening has the effect of suppressing current period results in relation to the comparable prior period, while yen strengthening has the effect of magnifying current period results in relation to the comparable prior period. Management evaluates the Company's financial performance both including and excluding the impact of foreign currency translation to monitor, respectively, cumulative currency impacts on book value and the currency-neutral operating performance over time.
RESULTS OF OPERATIONS BY SEGMENT
U.S. GAAP financial reporting requires that a company report financial and descriptive information about operating segments in its annual and interim period financial statements. Furthermore, the Company is required to report a measure of segment profit or loss, certain revenue and expense items, and segment assets. Aflac's insurance business consists of two segments: Aflac Japan and Aflac U.S. Aflac Japan is the principal contributor to consolidated earnings. Businesses that are not individually reportable, such as the Parent Company, issued 60.0 billionasset management subsidiaries and business activities, including reinsurance retrocession activities are included in the Corporate and other segment. See the Item 1. Business section of this Form 10-K for a summary of each segment's products and distribution channels, and a discussion of the conversion of Aflac Japan from a branch to a subsidiary and the creation of asset management subsidiaries in 2018. Consistent with U.S. GAAP guidance for segment reporting, pretax adjusted earnings is the Company's U.S. GAAP measure of segment performance. See Note 2 of the Notes to the Consolidated Financial Statements for the reconciliation of segment results to the Company's consolidated U.S. GAAP results and additional information.

In yen terms, Aflac Japan's net premium income decreased in 2019, primarily due to limited-pay products reaching paid-up status. Net investment income, net of amortized hedge costs, increased in 2019 primarily due to increased investments in U.S. dollar-denominated floating rate assets and $25 million of income related to a partial call of a concentrated yen-denominated exposure.

Annualized premiums in force at December 31, 2019, were ¥1.49 trillion, compared with ¥1.53 trillion in 2018. The decrease in annualized premiums in force in yen of subordinated debentures through2.5% in 2019and 1.6% in 2018 was driven primarily by limited-pay products reaching paid up status. Annualized premiums in force, translated into dollars at respective year-end exchange rates, were $13.6 billion in 2019 and $13.8 billion in 2018.

Aflac Japan's investment portfolios include U.S. dollar-denominated securities and reverse-dual currency securities (yen-denominated debt securities with dollar coupon payments). In years when the yen strengthens in relation to the dollar, translating Aflac Japan's U.S. dollar-denominated investment income into yen lowers growth rates for net investment income, total adjusted revenues, and pretax adjusted earnings in yen terms. In years when the yen weakens, translating U.S. dollar-denominated investment income into yen magnifies growth rates for net investment income, total adjusted revenues, and pretax adjusted earnings in yen terms.
The following table illustrates the effect of translating Aflac Japan's U.S. dollar-denominated investment income and related items into yen by comparing certain segment results with those that would have been reported had dollar/yen exchange rates remained unchanged from the prior year. Amounts excluding foreign currency impact on U.S. dollar-denominated investment income, a U.S. public debt offering. non-U.S. GAAP financial measure, were determined using the average dollar/yen exchange rate for the comparable prior year period. See non-U.S. GAAP financial measures defined above.

In 2019, the adjusted expense ratio increased mainly due to lower premium income from paid-up first sector products and higher expenses for advanced technology implementation. In total for 2019, the pretax adjusted profit margin (calculated by dividing adjusted earnings by adjusted revenues) increased reflecting continued strength in benefit ratios and favorable net investment income. For 2020, the Company anticipates the Aflac Japan pretax adjusted profit margin (calculated by dividing adjusted earnings by adjusted revenues) to remain stable.

The foundation of Aflac Japan's product portfolio has been, and continues to be, third sector products, which include cancer, medical and income support insurance products. Aflac Japan has been focusing more on promotion of cancer and medical insurance products in this low-interest-rate environment. These products are less interest-rate sensitive and more profitable compared to first sector savings products. With continued cost pressure on Japan’s health care system, the Company expects the need for third sector products will continue to rise in the future and that the medical and cancer insurance products Aflac Japan provides will continue to be an important part of its product portfolio.

Sales of protection-type first sector and third sector products on a yen basis decreased 16.8% in 2019, compared with 2018. Earned premium growth for third and first sector protection products was $13 million.1.3%, which was consistent with the Company's expectation. The decline in sales primarily reflected reduced sales of cancer insurance through the Japan Post channel following the 2018 launch of Aflac Japan's revised cancer insurance product. In addition, the approach to refreshing the medical insurance product in 2019 took a rider versus whole policy approach. This was designed for improved economics but naturally resulted in lower reported sales. Additional factors include a change in corporate tax law, which slowed the pace of certain third sector medical products and some cancer products in both our associate channel and the bank channel, as well as increased competition from large life insurers who are increasing their focus on the third sector.


Sales of Aflac Japan cancer products in the Japan Post Group channel experienced a material decline beginning in August 2019 which has continued into 2020. For 2019, sales in the Japan Post Group channel declined by approximately 50.0% compared with 2018. The Company expects very little sales production in the Japan Post channel during the first half of 2020 and is uncertain with regard to production during the second half of the year. See the 2020 Outlook section of this MD&A for information on Aflac Japan earned premium expectations.

Independent corporate agencies and individual agencies contributed 45.7% of total new annualized premium sales for Aflac Japan in 2019, compared with 40.1% in 2018. Affiliated corporate agencies, which include Japan Post, contributed 50.0% of total new annualized premium sales in 2019, compared with 55.3% in 2018. Japan Post offers Aflac's cancer insurance products in more than 20,000 postal outlets. Notwithstanding the recent reduction in sales of Aflac Japan's cancer products in the Japan Post channel, the Company believes this alliance with Japan Post has and will benefit its cancer insurance sales over the long term. In January 2017,2019, Aflac Japan recruited 77 new sales agencies. At December 31, 2019, Aflac Japan was represented by more than 9,000 sales agencies, with more than 109,000 licensed sales associates employed by those agencies.

At December 31, 2019, Aflac Japan had agreements to sell its products at 367 banks, approximately 90% of the Parent Company issued 60.0 billion yentotal number of senior notes through a U.S. public debt offering. In February 2017, the Parent Company extinguished $650 millionbanks in Japan. Bank channel sales accounted for 4.3% of 2.65% senior notes upon their maturity.new annualized premium sales in 2019 for Aflac Japan, compared with 4.6% in 2018.


In 2017,Strategic Alliance with Japan Post Holdings

On December 19, 2018, the Parent Company and Aflac renewedJapan entered into a 364-day uncommitted bilateralBasic Agreement with Japan Post Holdings a Japanese corporation. Pursuant to the terms of the Basic Agreement, Japan Post Holdings agreed to form a capital relationship with the Parent Company, and Japan Post Holdings and Aflac Japan agreed to reconfirm existing initiatives regarding cancer insurance and to consider new joint initiatives, including leveraging digital technology in various processes, cooperation in new product development to promote customer-centric business management, cooperation in domestic and/or overseas business expansion and joint investment in third party entities and cooperation regarding asset management.

Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations

On February 28, 2019, the Parent Company entered a Shareholders Agreement with Japan Post Holdings, J&A Alliance Holdings Corporation, a Delaware corporation, solely in its capacity as trustee of J&A Alliance Trust, a New York voting trust (Trust), and General Incorporated Association J&A Alliance, a Japanese general incorporated association. Pursuant to the terms of the Shareholders Agreement, the Trust will use commercially reasonable efforts to acquire, through open market or private block purchases in the U.S., beneficial ownership of approximately 7% of the outstanding shares of the Parent Company’s common stock within a period of 12 months following the date the Trust begins acquiring such stock. On May 7, 2019, a press release issued by Japan Post Holdings announced that purchases of shares of the Parent Company’s common stock commenced on April 29, 2019 through the Trust and that it planned to complete such purchases within Japan Post’s fiscal year 2019 (which ends March 31, 2020).

The Trust has agreed not to own more than 10% of the Parent Company’s outstanding shares for a period expiring on the earlier of four years after the Trust acquires 7% of such shares, five years after it acquires 5% of such shares, or ten years after the Trust begins acquiring the Parent Company’s stock. After expiration of such period, the Trust has agreed not to own more than the greater of 10% of the Parent Company’s outstanding shares or such shares representing 22.5% of the voting rights in the Parent Company.

In light of the fact that the shares acquired by the Trust, like all Aflac Incorporated common shares, will be eligible for 10-for-1 voting rights after being held for 48 consecutive months, the Shareholders Agreement further provides for voting restrictions that effectively limit the trustee’s voting rights to no more than 20% of the voting rights in the Parent Company and further restrict the trustee’s voting rights with respect to certain change in control transactions. Japan Post Holdings will not have a Board seat on the Parent Company’s Board of Directors and will not have rights to control, manage or intervene in the management of the Parent Company.

As of December 31, 2019, all regulatory approvals expressly set forth in the Shareholders Agreement have been obtained. The Shareholders Agreement requires the parties to use reasonable best efforts to cooperate in connection with any ongoing regulatory matters related to or arising from the Trust’s acquisition or ownership or control of the shares of Company Common Stock, including any applications or filings in connection with a direct or indirect acquisition of control of or merger with an insurer by the Company or its affiliates. The foregoing is subject to and qualified in its entirety by reference to the full text of the Shareholders Agreement, a copy of which is attached as Exhibit 10.50 to the Company’s Quarterly Report on Form 10-Q filed April 26, 2019, and the terms of which exhibit are incorporated herein by reference.

Aflac Japan Investments

The level of investment income in yen is affected by available cash flow from operations, the timing of investing the cash flow, yields on new investments, the effect of yen/dollar exchange rates on U.S. dollar-denominated investment income, and other factors.

As part of the Company's portfolio management and asset allocation process, Aflac Japan invests in yen and U.S. dollar-denominated investments. Yen-denominated investments primarily consist of JGBs and public and private fixed maturity securities. Aflac Japan's U.S. dollar-denominated investments include fixed maturity investments and growth assets, including public equity securities and alternative investments in limited partnerships or similar investment vehicles. Aflac Japan has been investing in both publicly-traded and privately originated U.S. dollar-denominated investment-grade and below-investment-grade fixed maturity securities and loan receivables, and has entered into foreign currency forwards and options to hedge the currency risk on the fair value of a portion of the U.S. dollar investments.

The benefit ratio decreased in 2019, compared with 2018, primarily due to somewhat elevated lapses and a change in business mix from higher loss ratio, reserve building products to lower loss ratio, guaranteed issue products. The adjusted expense ratio increased in 2019, compared with 2018, primarily due to deferred policy acquisition costs (DAC) capitalization related to lower than anticipated sales as well as anticipated spending increases reflecting ongoing investments in the U.S. platform, distribution, and customer experience. Both the lower benefit and higher DAC amortization ratios were also impacted by increases in lapses as a result of large case volatility and replacement of an administrative partner. These items impacted persistency in the short-term but are expected to drive profitable earned premium growth in future periods. The pretax adjusted

While overall sales decreased in 2019, net earned premium increased 1.8%.
In 2019, the Aflac U.S. sales forces included an average of approximately 8,200 U.S. agents, including brokers, who were actively producing business on a weekly basis. The Company believes that this average weekly producer equivalent metric allows sales management to monitor progress and needs.

In November 2019, the Company acquired Argus Holdings, LLC and its subsidiary Argus Dental & Vision, Inc. (Argus), a benefits management organization and national network dental and vision company, which provides a platform for Aflac Dental and Vision. This transaction represents a commitment of $75 million in capital at closing and an additional $21 million in consideration paid over three years based on the achievement by Argus of certain performance targets. Tampa, Florida will serve as the home for Aflac Dental and Vision. This acquisition is a strategic entry point into the network dental and vision market and is expected to provide opportunities for sales growth, improved account penetration and distribution productivity.

Net investment income benefited from the Company’s enterprise corporate hedging program for the years ended December 31, 2019 and 2018, respectively. See the Hedging Activities subsection of this MD&A for further information on the enterprise corporate hedging program.

In December 2018, the Parent Company invested $20 million in Singapore Life Pte. Ltd. (Singapore Life), a digitally-focused life insurance company based in Singapore. The Parent Company made an additional investment of $16 million in the second quarter of 2019, bringing the total investment to $36 million. As part of the relationship, Aflac entered into a reinsurance agreement on certain protection products with Singapore Life in September 2019. However, the Company does not currently expect the equity investment or the reinsurance agreement to have a material impact on its financial position or results of operations.

INVESTMENTS

The Company’s investment strategy utilizes disciplined asset and liability management while seeking long-term risk-adjusted investment returns and the delivery of stable income within regulatory and capital objectives, and preserving shareholder value. In attempting to optimally balance these objectives, the Company seeks to maintain on behalf of Aflac Japan a diversified portfolio of yen-denominated investment assets, a U.S. dollar-denominated investment portfolio hedged back to yen and a portfolio of unhedged U.S. dollar-denominated assets. As part of the Company's portfolio management and asset allocation process, Aflac U.S. invests in fixed maturity investments and growth assets, including public equity securities and alternative investments in limited partnerships. Aflac U.S. invests in both publicly traded and privately originated investment-grade and below-investment-grade fixed maturity securities and loans.

Generally, declines in fair values can be a result of changes in interest rates, yen/dollar exchange rate, and changes in net spreads driven by a broad market move or a change in the issuer's underlying credit quality. As the Company believes these issuers have the ability to continue making timely payments of principal and interest, the Company views these changes in fair value to be temporary. See the Unrealized Investment Gains and Losses section in Note 3 of the Notes to the Consolidated Financial Statements for further discussions of unrealized losses related to financial institutions and other corporate investments.
Below-Investment-Grade Securities
The Company's portfolio of below-investment-grade securities includes debt securities purchased while the issuer was rated investment grade plus other loans and bonds purchased as part of an allocation to that segment of the market. The following is the Company's below-investment-grade exposure.

(1) Securities initially purchased as investment grade, but have subsequently been downgraded to below investment grade
(2) Middle market loans are carried at amortized cost

The Company invests in senior secured bank loans and middle market loans primarily to U.S. corporate borrowers, most of which have below-investment-grade ratings. The objectives of these programs include enhancing the yield on invested assets, achieving further diversification of credit risk, and mitigating the risk of rising interest rates and hedge costs through the acquisition of floating rate assets.

The Company maintains an allocation to higher yielding corporate bonds within the Aflac Japan and Aflac U.S. portfolios. Most of these securities were rated below-investment-grade at the time of purchase, but the Company also purchased several that were rated investment grade which, because of market pricing, offer yields commensurate with below-investment-grade risk profiles. The objective of this allocation was to enhance the Company's yield on invested assets and further diversify credit risk. All investments in this program must have a minimum rating at purchase of low BB using the Company's above described rating methodology and are managed by the Company's internal credit portfolio management team.
Fixed Maturity Securities by Sector
The Company maintains diversification in investments by sector to avoid concentrations to any one sector, thus managing exposure risk. The following table shows the distribution of fixed maturities by sector classification as of December 31.

Securities by Type of Issuance
The Company has investments in both publicly and privately issued securities. The Company's ability to sell either type of security is a function of overall market liquidity which is impacted by, among other things, the amount of outstanding securities of a particular issuer or issuance, trading history of the issue or issuer, overall market conditions, and idiosyncratic events affecting the specific issue or issuer.

Aflac Japan has a portfolio of privately issued securities to better match liability characteristics and secure higher yields than those available on Japanese government or other public corporate bonds.Aflac Japan’s investments in yen-denominated privately issued securities consist primarily of non-Japanese issuers, are rated investment grade at purchase and have longer maturities, thereby allowing the Company to improve asset/liability matching and overall investment returns. These securities are generally either privately negotiated arrangements or issued under medium-term note programs and have standard documentation commensurate with credit ratings of the issuer, except when internal credit analysis indicates that additional protective and/or event-risk covenants were required. Many of these investments have protective covenants appropriate to the specific investment. These may include a prohibition of certain activities by the borrower, maintenance of certain financial measures, and specific conditions impacting the payment of the Company's notes.

HEDGING ACTIVITIES

The Company uses derivative contracts to hedge foreign currency exchange rate risk and interest rate risk. The Company uses various strategies, including derivatives, to manage these risks. See item “7A. Quantitative and Qualitative Disclosures About Market Risk” for more information about Market risk and the Company’s use of derivatives.

Derivatives are designed to reduce risk on an economic basis while minimizing the impact on financial results. The Company’s derivatives programs vary depending on the type of risk being hedged. See Note 4 of the Notes to the Consolidated Financial Statements for:

A description of the Company's derivatives, hedging strategies and underlying risk exposure.
Information about the notional amount and fair market value of the Company's derivatives.
The unrealized and realized gains and losses impact on adjusted earnings of derivatives in cash flow, fair value, net investments in foreign operations, or non-qualifying hedging relationships.

Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations

Foreign Currency Exchange Rate Risk Hedge Program

The Company has deployed the following hedging strategies to mitigate exposure to foreign currency exchange rate risk:

Aflac Japan hedges U.S. dollar-denominated investments back to yen (see Aflac Japan’s U.S. Dollar-Denominated Hedge Program below).

Aflac Japan maintains certain unhedged U.S. dollar-denominated securities, which serve as an economic currency hedge of a portion of the Company's investment in Aflac Japan (see Aflac Japan’s U.S. Dollar-Denominated Hedge Program below).

The Parent Company designates yen-denominated liabilities (notes payable and loans) as non-derivative hedging instruments and designates certain foreign currency forwards and options as derivative hedges of the Company’s net investment in Aflac Japan (see Enterprise Corporate Hedging Program below).

The Parent Company enters into forward and option contracts to accomplish a dual objective of hedging foreign currency exchange rate risk related to dividend payments by its subsidiary, ALIJ, and reducing enterprise-wide hedge costs. (see Enterprise Corporate Hedging Program below).

Aflac Japan’s U.S. Dollar-Denominated Hedge Program

Aflac Japan buys U.S. dollar-denominated investments, typically corporate bonds, and hedges them back to yen with foreign currency forwards and options to hedge foreign currency exchange rate risk. This economically creates yen assets that match yen liabilities during the life of the derivative and provides capital relief. The currency risk being hedged is generally based on fair value of hedged investments. The following table summarizes the U.S. dollar-denominated investments held by Aflac Japan as of December 31.

U.S. Dollar Program includes all U.S. dollar-denominated investments in Aflac Japan other than the investments in certain consolidated VIEs where the instrument is economically converted to yen as a result of a derivative in the consolidated variable interest entity. As of December 31, 2019, Aflac Japan had $8.8 billion outstanding notional amounts of foreign currency forwards and $21.1 billion outstanding notional amounts of foreign currency options, of which none were in-the-money, hedging the U.S. dollar-denominated investments. The fair value of Aflac Japan's unhedged U.S. dollar-denominated portfolio was $19.9 billion (excluding certain U.S. dollar-denominated assets shown in the table above as a result of consolidation that have been economically converted to yen using derivatives).

Foreign exchange derivatives used for hedging are periodically settled, which results in cash receipt or payment at maturity or early termination. The Company had net cash outflows of $20 million in 2019, net cash inflows of $272 million in

55


Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations

2018 and net cash outflows of $747 million in 2017, associated with the currency derivatives used for hedging Aflac Japan’s U.S. dollar-denominated investments.

Enterprise Corporate Hedging Program

The Company has designated certain yen-denominated liabilities and foreign currency forwards and options of the Parent Company as accounting hedges of its net investment in Aflac Japan. The Company's consolidated yen-denominated net asset position was partially hedged at $9.1 billion as of December 31, 2019, compared with $1.8 billion as of December 31, 2018.

The Company makes its accounting designation of net investment hedge at the beginning of each quarter. If the total of the designated Parent Company non-derivative and derivative notional is equal to or less than the Company's net investment in Aflac Japan, the hedge is deemed to be effective, and the currency exchange effect on the yen-denominated liabilities and the change in estimated fair value of the derivatives are reported in the unrealized foreign currency component of other comprehensive income. The Company's net investment hedge was effective during the years ended December 31, 2019 and 2018, respectively. For additional information on the Company's net investment hedging strategy, see Note 4 of the Notes to the Consolidated Financial Statements.

In order to economically mitigate risks associated with the enterprise-wide exposure to the yen and the level and volatility of hedge costs, the Parent Company enters into foreign exchange forward and option contracts. By buying U.S. dollars and selling yen, the Parent Company is effectively lowering its overall economic exposure to the yen, while Aflac Japan's U.S dollar exposure remains reduced as a result of Aflac Japan's U.S. dollar-denominated hedge program that economically creates yen assets. Among other objectives, this strategy is intended to offset the enterprise-wide amortized hedge costs by generating amortized hedge income. The portion of the enterprise-wide amortized hedge income contributed by this strategy was $89 million in 2019 and $36 million in 2018. This activity is reported in Corporate and Other. As this program evolves, the Company will continue to evaluate the program’s efficacy. See the Results of Operations section of this MD&A for the Company's definition of amortized hedge costs/income.

The following table presents metrics related to Aflac Japan amortized hedge costs and the Parent Company amortized hedge income for the years ended December 31.

Interest Rate Risk Hedge Program

Aflac Japan and Aflac U.S. use interest rate swaps to mitigate the risk of investment income volatility for certain variable-rate investments. Additionally, to manage interest rate risk associated with its U.S. dollar-denominated investments held by Aflac Japan, the Company utilizes interest rate swaptions.

For additional discussion of the risks associated with the foreign currency exposure refer to the Currency Risk section in Item 1A, specifically to the Risk Factors titled “The Company is exposed to foreign currency fluctuations in the yen/dollar exchange rate“ and “Lack of availability of acceptable yen-denominated investments could adversely affect the Company's results of operations, financial position or liquidity."

BENEFIT PLANS

Aflac Japan and Aflac U.S. have various benefit plans. For additional information on the Company's Japanese and U.S. plans, see Note 14 of the Notes to the Consolidated Financial Statements.

POLICYHOLDER PROTECTION
Policyholder Protection Corporation

The Japanese insurance industry has a policyholder protection system that provides funds for the policyholders of insolvent insurers. Legislation enacted regarding the framework of the Life Insurance Policyholder Protection Corporation (LIPPC) included government fiscal measures supporting the LIPPC. In November 2016, Japan's Diet passed legislation that again extends the government's fiscal support of the LIPPC through March 2022. Effective April 2014, the annual LIPPC contribution amount for the total life industry was lowered from ¥40 billion to ¥33 billion. Aflac Japan recognized an expense of ¥1.9 billion and ¥2.0 billion for the years ended December 31, 2019 and 2018, respectively, for LIPPC assessments.

Guaranty Fund Assessments

Under U.S. state guaranty association laws, certain insurance companies can be assessed (up to prescribed limits) for certain obligations to the policyholders and claimants of impaired or insolvent insurance companies that write the same line or similar lines of business. The amount of the guaranty fund assessment that an insurer is assessed is based on its proportionate share of premiums in that state. See Note 15 of the Notes to the Consolidated Financial Statements for further information on the assessment.

OFF-BALANCE SHEET ARRANGEMENTS

As of December 31, 2019, the Company had no material letters of credit, standby letters of credit, guarantees or standby repurchase obligations. See Note 15 of the Notes to the Consolidated Financial Statements for information on material unconditional purchase obligations that are not recorded on the Company's balance sheet.

LIQUIDITY AND CAPITAL RESOURCES
Liquidity refers to the ability to generate sufficient cash resources to meet the payment obligations of the Company. Capital refers to the long-term financial resources available to support the operations of the businesses, fund business growth and provide for an ability to withstand adverse circumstances. Financial leverage (leverage) refers to an investment strategy of using debt to increase the potential return on equity. The Company targets and actively manages liquidity, capital and leverage in the context of a number of considerations, including:

business investment and growth needs
strategic growth objectives
financial flexibility and obligations
capital support for hedging activity
a constantly evolving business and economic environment
a balanced approach to capital allocation and shareholder deployment.

The governance framework supporting liquidity, capital and leverage includes global senior management and board committees that review and approve all significant capital related decisions.

The Company's cash and cash equivalents include unrestricted cash on hand, money market instruments, and other debt instruments with a maturity of 90 days or less when purchased, all of which has minimal market, settlement or other risk exposure. The target minimum amount for the Parent Company’s cash and cash equivalents is approximately $2.0 billion to provide available capital and liquidity support at the holding company.Aflac Japan and Aflac U.S. provide the primary sources of liquidity to the Parent Company through the payment of dividends and management fees. The following table presents the amounts provided to the Parent Company for the years ended December 31.

The decline in dividends during 2018 was driven by a change in the dividend regulatory approval process subsequent to the conversion of Aflac Japan from a branch to a subsidiary on April 1, 2018. The Company resumed dividend payments from Aflac Japan in the fourth quarter of 2018. Management fees decreased during 2019 and 2018, compared to prior years, due to changes in the administration of intercompany expenses between legal entities subsequent to the conversion, as well.

Prior to the Aflac Japan branch conversion, Aflac Japan paid allocated expenses and profit remittances to Aflac U.S. The following table details Aflac Japan remittances for the years ended December 31.

In 2018, the Company announced a change in its internal dividend policy which allows the Company to increase the proportion of regulatory earnings transferred from Aflac U.S. and Aflac Japan to the Parent Company. The Company intends to maintain higher than historical levels of capital and liquidity at the Parent Company with the goals of addressing the Company’s hedge costs and related potential need for collateral and mitigating against long-term weakening of the Japanese yen. Further, the Company plans to continue to maintain a portfolio of unhedged U.S. dollar based investments at Aflac Japan and consider whether the amount of such investments should be increased or decreased relative to the Company’s view of economic equity surplus in Aflac Japan in light of potentially rising hedge costs and other factors. See the "Hedging Activity" subsection in this MD&A for more information.

Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations

In addition to cash and equivalents, the Company also maintains credit facilities, both intercompany and with external partners, and a number of other available tools to support liquidity needs on a global basis. In September 2018, the Parent Company filed a shelf registration statement with the SEC that allows the Company to issue an indefinite amount of debt securities, in one or more series, from time to time until September 2021. In August 2018, the Parent Company filed a shelf registration with Japanese regulatory authorities that allows the Parent Company to conduct public offerings of bonds in Japan, including yen-denominated Samurai notes, up to ¥200 billion or its equivalent through August 2020. The shelf registration statement is for possible public offerings in Japan, but the bonds issued under the shelf may be transferred by the bondholders to U.S. persons in compliance with U.S. law. The Company believes outside sources for additional debt and equity capital, if needed, will continue to be available. Additionally, as of December 31, 2019, the Parent Company and Aflac had four lines of credit with a third party that provides for borrowings in the amount of $100 millionparties and executed two 364-daythree intercompany uncommitted and revolving lines of credit, one of which provides for borrowings by Aflac in the amount of $250 million, and the other provides for borrowings by the Parent Company in the amount of 37.5 billion yen.

credit. For furtheradditional information, regarding these transactions, see Note 9 of the Notes to the Consolidated Financial StatementsStatements.

The primary uses of cash by the Parent Company are shareholder dividends, the repurchase of its common stock and interest on its outstanding indebtedness and operating expenses.

Liabilities for unrecognized tax benefits in the amount of $17 have been excluded from the tabular disclosure above because the timing of cash payment is not reasonably estimable.
(1)Liability amounts are those reported on the consolidated balance sheet as of December 31, 2019.
(2)The estimated payments due by period reflect future estimated cash payments to be made to policyholders and others for future policy benefits. These projected cash outflows are based on assumptions for future policy persistency, mortality, morbidity, and other assumptions comparable with the Company's experience, consider future premium receipts on current policies in force, and assume market growth and interest crediting consistent with assumptions used in amortizing deferred acquisition costs. These cash outflows are undiscounted with respect to interest and, as a result, the sum of the cash outflows shown for all years in the table of $244,884 exceeds the corresponding liability amount of $90,335. The Company has made significant assumptions to determine the future estimated cash outflows related to the underlying policies and contracts. Due to the significance of the assumptions used, actual cash outflow amounts and timing will differ, possibly materially, from these estimates.

including securities lending transactions. See Notes 1, 3, and 4 of the Notes to the Consolidated Financial Statements for more information on the Company's securities lending and derivative activities. With the exception of disclosed activities in those referenced footnotes and the Risk Factors entitled, "The Company is exposed to foreign currency fluctuations in the yen/dollar exchange rate" and "Lack of availability of acceptable yen-denominated investments could adversely affect the Company's results of operations, financial position or liquidity," the Company is not aware of a trend, demand, commitment, event or uncertainty that would likely result in its liquidity increasing or decreasing by a material amount.
Consolidated Cash Flows

The Company repurchased 17.8translates cash flows for Aflac Japan's yen-denominated items into U.S. dollars using weighted-average exchange rates. In years when the yen weakens, translating yen into dollars causes fewer dollars to be reported. When the yen strengthens, translating yen into dollars causes more dollars to be reported.

Operating Activities
The principal cash inflows for the Company's insurance activities come from insurance premiums and investment income. The principal cash outflows are the result of policy claims, operating expenses, income tax, as well as interest expense. As a result of policyholder aging, claims payments are expected to gradually increase over the life of a policy. Therefore, future policy benefit reserves are accumulated in the early years of a policy and are designed to help fund future claims payments.
The Company expects its future cash flows from premiums and its investment portfolio to be sufficient to meet its cash needs for benefits and expenses. Consolidated cash flow from operations decreased 9.3% in 2019, compared with 2018.
Investing Activities
The Company's investment objectives provide for liquidity primarily through the purchase of publicly traded investment-grade debt securities. Prudent portfolio management dictates that the Company attempts to match the duration of its assets with the duration of its liabilities. Currently, when the Company's fixed maturity securities mature, the proceeds may be reinvested at a yield below that required for the accretion of policy benefit liabilities on policies issued in earlier years. However, the long-term nature of the Company's business and its strong cash flows provide the Company with the ability to minimize the effect of mismatched durations and/or yields identified by various asset adequacy analyses. From time to time or when market opportunities arise, the Company disposes of selected fixed maturity securities that are available for sale to improve the duration matching of assets and liabilities, improve future investment yields, and/or re-balance its portfolio. As a result, dispositions before maturity can vary significantly from year to year.

As part of its overall corporate strategy, the Company has announced an increase in its commitment to the Aflac Ventures Fund from $250 million to $400 million, as opportunities emerge. These investments are included in equity securities or the other investments line in the consolidated balance sheets. The Aflac Ventures Fund is a subsidiary of Aflac Corporate Ventures which is reported in the Corporate and other segment. The central mission of Aflac Corporate Ventures is to support the organic growth and business development needs of Aflac Japan and Aflac U.S. with emphasis on digital applications designed to improve the customer experience, gain efficiencies, and develop new markets in an effort to enhance and defend long-term shareholder value.

As part of an arrangement with Federal Home Loan Bank of Atlanta (FHLB), Aflac U.S. obtains low-cost funding from FHLB supported by acceptable forms of collateral pledged by Aflac U.S. Aflac U.S. borrowed and repaid $217 million under this program during 2019. As of December 31, 2019, Aflac U.S. had outstanding borrowings of $403 million reported in its balance sheet.

Financing Activities

Consolidated cash used by financing activities was $1.7 billion in 2019 and $1.6 billion in 2018.

In December 2019, the Parent Company issued four series of senior notes totaling ¥38.0 billion through a public debt offering under its U.S. shelf registration statement. The first series, which totaled ¥12.6 billion, bears interest at a fixed rate of .500% per annum, payable semi-annually, and will mature in December 2029. The second series, which totaled ¥9.3 billion, bears interest at a fixed rate of .843% per annum, payable semi-annually, and will mature in December 2031. The third series, which totaled ¥9.8 billion, bears interest at a fixed rate of .934% per annum, payable semi-annually, and will mature in December 2034. The fourth series, which totaled ¥6.3 billion, bears interest at a fixed rate of 1.122% per annum, payable semi-annually, and will mature in December 2039. These notes may only be redeemed before maturity, in whole but not in part, upon the occurrence of certain changes affecting U.S. taxation, as specified in the indenture governing the terms of the issuance.

In September 2019, the Parent Company renewed a ¥30.0 billion senior term loan facility. The first tranche of the facility, which totaled ¥5.0 billion, bears interest at a rate per annum equal to the Tokyo interbank market rate (TIBOR), or alternate TIBOR, if applicable, plus the applicable TIBOR margin and will mature in September 2026. The applicable margin ranges between .30% and .70%, depending on the Parent Company's debt ratings as of the date of determination. The second tranche, which totaled ¥25.0 billion, bears interest at a rate per annum equal to the TIBOR, or alternate TIBOR, if applicable, plus the applicable TIBOR margin and will mature in September 2029. The applicable margin ranges between .45% and 1.00%, depending on the Parent Company's debt ratings as of the date of determination.

In April 2019, ALIJ issued ¥30.0 billion (par value) of perpetual subordinated bonds. These bonds bear interest at a fixed rate of .963% per annum and then at six-month Euro Yen LIBOR plus an applicable spread on and after the day immediately following April 18, 2024. The bonds will be callable on each interest payment date on and after April 18, 2024. In November 2019, ALIJ amended the bonds to change their duration from perpetual to a stated maturity date of April 16, 2049 and to remove provisions that permitted ALIJ to defer payments of interest under certain circumstances.

In October 2018, the Parent Company issued $550 million of senior notes through a U.S. public debt offering. The notes bear interest at a fixed rate of 4.750% per annum, payable semi-annually, and will mature in January 2049. These notes are redeemable at the Parent Company's option in whole at any time or in part from time to time at a redemption price equal to the greater of: (i) the aggregate principal amount of the notes to be redeemed or (ii) the amount equal to the sum of the present values of the remaining scheduled payments for principal of and interest on the notes to be redeemed, not including any portion of the payments of interest accrued as of such redemption date, discounted to such redemption date on a semiannual basis at the yield to maturity for a U.S.Treasury security with a maturity comparable to the remaining term of the notes, plus 25 basis points, plus in each case, accrued and unpaid interest on the principal amount of the notes to be redeemed to, but excluding, such redemption date.

In October 2018, the Parent Company issued three series of senior notes totaling ¥53.4 billion through a public debt offering under its U.S. shelf registration statement. The first series, which totaled ¥29.3 billion, bears interest at a fixed rate of 1.159% per annum, payable semi-annually, and will mature in October 2030. The second series, which totaled ¥15.2 billion, bears interest at a fixed rate of 1.488% per annum, payable semi-annually, and will mature in October 2033. The third series, which totaled ¥8.9 billion, bears interest at a fixed rate of 1.750% per annum, payable semi-annually, and will mature in October 2038. These notes may only be redeemed before maturity, in whole but not in part, upon the occurrence of certain changes affecting U.S. taxation, as specified in the indenture governing the terms of the issuance.

In November 2018, the Parent Company used the net proceeds from the October 2018 issuance of its senior notes to redeem $550 million of the Parent Company's 2.40% senior notes due in 2020.

See Note 9 of the Notes to the Consolidated Financial Statements for further information on the debt issuances discussed above.

The Company was in compliance with all of the covenants of its notes payable and lines of credit at December 31, 2019.

Cash returned to shareholders through treasury stock purchases and dividends was $2.4 billion in 2019, compared with $2.1 billion in 2018.

The following tables present a summary of treasury stock activity during the years ended December 31.

Under share repurchase authorizations from the Company's board of directors, the Company purchased 32.0 million shares of its common stock in the open market for $1.35 billion under2019, compared with 28.9 million shares in 2018. As of December 31, 2019, a remaining balance of 37.1 million shares of the Company's common stock was available for purchase under share repurchase programauthorizations by its board of directors. The Company currently plans to repurchase $1.3 billion to $1.7 billion of its common stock in 2017,2020, assuming stable capital conditions and absent compelling alternatives. See Note 11 of the Notes to the Consolidated Financial Statements for additional information.

Cash dividends paid to shareholders in 2019 of $1.08 per share increased 3.8% over 2018. The following table presents the dividend activity for the years ended December 31.

Regulatory Restrictions

Aflac, CAIC and TOIC are domiciled in Nebraska and are subject to its regulations. Subsequent to the Japan branch conversion to a subsidiary, Aflac Japan is domiciled in Japan and subject to local regulations. The Nebraska Department of Insurance imposes certain limitations and restrictions on payments of dividends, management fees, loans and advances to the Parent Company. Under Nebraska insurance law, prior approval of the Nebraska Department of Insurance is required for dividend distributions that exceed the greater of the net income from operations, which excludes net realized investment gains, for the previous year determined under statutory accounting principles, or 10% of statutory capital and surplus as of the previous year-end. In addition, the Nebraska insurance department must approve service arrangements and other transactions within the affiliated group of companies. These regulatory limitations are not expected to affect the level of management fees or dividends paid to the Parent Company. (See below for discussion of restrictions imposed by Japanese insurance regulators.) A life insurance company’s statutory capital and surplus is determined according to rules prescribed by the NAIC, as modified by the insurance department in the insurance company’s state of domicile. Statutory accounting rules are different from U.S. GAAP and are intended to emphasize policyholder protection and company solvency. Similar laws apply in New York, the domiciliary jurisdiction of Aflac New York.


62


Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations

The continued long-term growth of the Company's business may require increases in the statutory capital and surplus of its insurance operations. Aflac’s insurance operations may secure additional statutory capital through various sources, such as internally generated statutory earnings, capital contributions by the Parent Company from funds generated through debt or equity offerings, or reinsurance transactions. The NAIC’s RBC formula is used by insurance regulators to help identify inadequately capitalized insurance companies. The RBC formula quantifies insurance risk, business risk, asset risk and interest rate risk by weighing the types and mixtures of risks inherent in the insurer’s operations.

Aflac's company action level RBC ratio was 539% as of December 31, 2019, compared with 560% at December 31, 2018. Aflac’s RBC ratio remains high and reflects a strong capital and surplus position. As of December 31, 2019, Aflac's total adjusted capital of $2.2 billion exceeded the company action level required capital and surplus of $.4 billion by $1.8 billion. With the announcement of the Japan branch conversion to a subsidiary, we had announced our intention to remove excess capital out of Aflac, targeting a 500% RBC by the end of 2019. As of December 31, 2019, the Company has completed the RBC drawdown plan and has moved $1.75 billion of capital from Aflac to the Parent Company, supporting the Company's capital deployment and risk management activities.

The maximum amount of dividends that can be paid to the Parent Company by Aflac, CAIC and TOIC without prior approval of Nebraska's director of insurance is the greater of the net income from operations, which excludes net realized investment gains, for the previous year determined under statutory accounting principles, or 10% of statutory capital and surplus as of the previous year-end. Dividends declared by Aflac during 2020 in excess of $864 million would be considered extraordinary and require such approval. Following the Japan branch conversion to a subsidiary, the Company used extraordinary dividends as needed to actively manage to appropriate RBC levels that are lower yet sufficient to maintain ratings and support prudent capital management. Similar laws apply in New York, the domiciliary jurisdiction of Aflac New York. See Note 13 of the Notes to the Consolidated Financial Statements for information regarding the impact of permitted practices by the Nebraska Department of Insurance on the Company's statutory capital and surplus.

The NAIC considers its Solvency Modernization Initiative (SMI) process relating to updating the U.S. insurance solvency regulation framework to be ongoing. The SMI has focused on key issues such as capital requirements, governance and risk management, group supervision, reinsurance, statutory accounting and financial reporting matters. Many of these key issues have been finalized and/or are near completion; however, the NAIC still has some ongoing initiatives related to SMI, such as monitoring the international efforts on group capital requirements as well as RBC.In addition, the NAIC is also considering changes to investment risk factors. Any negative developments by the NAIC in these areas could result in increased capital requirements for the Company.

Aflac is subject to the NAIC’s Own Risk and Solvency Assessment (ORSA). Through the ORSA requirements, Aflac is expected to regularly, no less than annually, conduct an ORSA to assess the adequacy of its risk management framework, and its current and estimated projected future solvency position; internally document the process and results of the assessment; and provide a confidential high-level ORSA Summary Report annually to the lead state commissioner if the insurer is a member of an insurance group. In November 2019, Aflac filed its ORSA report with the Nebraska Department of Insurance.

In addition to limitations and restrictions imposed by U.S. insurance regulators, after the Japan branch conversion on April 1, 2018, the new Japan subsidiary is required to meet certain financial criteria as governed by Japanese corporate law in order to provide dividends to the Parent Company. Under these criteria, dividend capacity at the Japan subsidiary is basically defined as total equity excluding common stock, accumulated other comprehensive income amounts, capital reserves (representing statutorily required amounts in Japan) but reduced for net after-tax unrealized losses on available-for-sale securities. These dividend capacity requirements are generally aligned with the SMR. Japan's FSA maintains its own solvency standard which is quantified through the SMR. Aflac Japan's SMR is sensitive to interest rate, credit spread, and foreign exchange rate changes, therefore the Company continues to evaluate alternatives for reducing this sensitivity. In the event of a rapid change in market risk conditions causing SMR to decline, the Company has one senior unsecured revolving credit facility in the amount of ¥100 billion and a committed reinsurance facility in the amount of approximately ¥110 billion as a capital contingency plan. Additionally, the Company could take action to enter into derivatives on unhedged U.S. dollar-denominated investments with foreign currency options or forwards. See Notes 8 and 9 of the Notes to the Consolidated Financial Statements for additional information.

The Company has already undertaken various measures to mitigate the sensitivity of Aflac Japan's SMR. For example, the Company employs policy reserve matching (PRM) investment strategies, which is a Japan-specific accounting treatment that reduces SMR interest rate sensitivity since PRM-designated investments are carried at amortized cost consistent with corresponding liabilities. In order for a PRM-designated asset to be held at amortized cost, there are certain criteria that must be maintained. The primary criteria relates to maintaining the duration of designated assets and liabilities within a specified tolerance range. If the duration difference is not maintained within the specified range without rebalancing, then a certain

63


Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations

portion of the assets must be re-classified as available for sale and held at fair value with any associated unrealized gain or loss recorded in surplus. To rebalance, assets may need to be sold in order to maintain the duration with the specified range, resulting in realizing a gain or loss from the sale. For U.S. GAAP, PRM investments are categorized as available for sale. The Company also uses foreign currency derivatives to hedge a portion of its U.S. dollar-denominated investments.(See Notes 3, 4 and 8 of the Notes to the Consolidated Financial Statements for additional information on the Company's investment strategies, hedging activities, and reinsurance, respectively.)

Aflac's SMR ratio remains high and reflects a strong capital and surplus position. As of December 31, 2019, Aflac Japan's SMR was 1,043%, compared with 965% at December 31, 2018. As part of the conversion of Aflac Japan from a branch to a subsidiary on April 1, 2018, the Company experienced an accounting-driven decline in the SMR of approximately 130 points, compared with the repurchaseSMR as of 21.6 million sharesDecember 31, 2017. The Company expects to be able to pay dividends out of certain accounts, thus restoring this accounting impact over an estimated three-year period.

The FSA has been conducting field testing with the insurance industry concerning the introduction of an economic value-based solvency regime. The field testing will assist the FSA in determining if an economic value-based solvency regime in Japan will be appropriate for $1.4 billionthe insurance industry.

Privacy and Cybersecurity Governance

The Company’s Board of Directors has adopted an information security policy directing management to establish and operate a global information security program with the goals of monitoring existing and emerging threats and ensuring that the Company’s information assets and data, and the data of its customers, are appropriately protected from loss or theft. The Board has delegated oversight of the Company’s information security program to the Audit and Risk Committee. The Company’s senior officers, including its Global Security and Chief Information Security Officer, are responsible for the operation of the global information security program and regularly communicate with the Audit and Risk Committee on the program, including with respect to the state of the program, compliance with applicable regulations, current and evolving threats, and recommendations for changes in 2016.the information security program. The global information security program also includes a cybersecurity incident response plan that is designed to provide a management framework across Company functions for a coordinated assessment and response to potential security incidents. This framework establishes a protocol to report certain incidents to the Global Security and Chief Information Security Officer and other senior officers, with the goal of timely assessing such incidents, determining applicable disclosure requirements and communicating with the Audit and Risk Committee. The incident response plan directs the executive officers to report certain incidents immediately and directly to the Lead Non-Management Director.

CRITICAL ACCOUNTING ESTIMATES


The Company prepares its financial statements in accordance with U.S. generally accepted accounting principles (GAAP).GAAP. These principles are established primarily by the Financial Accounting Standards Board (FASB).FASB. In this MD&A, references to U.S. GAAP issued by the FASB are derived from the FASB Accounting Standards CodificationTMCodification™ (ASC). The preparation of financial statements in conformity with U.S. GAAP requires the Company to make estimates based on currently available information when recording transactions resulting from business operations. The estimates that the Company deems to be most critical to an understanding of Aflac'sAflac’s results of operations and financial condition are those related to the valuation of investments and derivatives, deferred policy acquisition costs (DAC),DAC, liabilities for future policy benefits and unpaid policy claims, and income taxes. The preparation and evaluation of these critical accounting estimates involve the use of various assumptions developed from management'smanagement’s analyses and judgments. The application of these critical accounting estimates determines the values at which 95%94% of the Company's assets and 81% of its liabilities are reported as

Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations

of December 31, 2017,2019, and thus has a direct effect on net earnings and shareholders' equity. Subsequent experience or use of other assumptions could produce significantly different results.


Valuation of Investments, Including Derivatives, and DerivativesRecognition of Other-than-Temporary Impairments


Aflac's investments, primarily consisting of debt perpetual and equity securities, include both publicly issued and privately issued securities. For publicly issued securities, the Company determines the fair values from quoted market prices readily available from public exchange markets and price quotes and valuations from third party pricing vendors. For the majority of privately issued securities within the Company's investment portfolio, a third party pricing vendor has developed valuation models that the Company utilizes to determine fair values. For the remaining privately issued securities, the Company uses non-binding price quotes from outside brokers.


The Company estimates the fair values of its securities on a monthly basis. The Company monitors the estimated fair values obtained from its pricing vendors and brokers for consistency from month to month, while considering current market conditions. The Company also periodically discusses with its pricing brokers and vendors the pricing techniques they use to monitor the consistency of their approach and periodically assess the appropriateness of the valuation level assigned to the values obtained from them. If a fair value appears unreasonable, the Company will re-examine the inputs and assess the reasonableness of the pricing data with the vendor. Additionally, the Company may compare the inputs to relevant market indices and other performance measurements. Based on management's analysis, the valuation is confirmed or may be revised if there is evidence of a more appropriate estimate of fair value based on available market data. The Company has performed verification of the inputs and calculations in any valuation models to confirm that the valuations represent reasonable estimates of fair value. Inputs used to value derivatives include, but are not limited to, interest rates, credit spreads, foreign currency forward and spot rates, and interest volatility.


The Company also routinely reviews its investments that have experienced declines in fair value to determine if the decline is other than temporary. The identification of distressed investments, the determination of fair value if not publicly traded and the assessment of whether a decline is other than temporary involve significant management judgment. The Company must apply considerable judgment in determining the likelihood of the security recovering in value while the Company owns it. Factors that may influence this include the Company's assessment of the issuer’s ability to continue making timely payments of interest and principal, the overall level of interest rates and credit spreads, and other factors. This process requires consideration of risks, which can be controlled to a certain extent, such as credit risk, and risks which cannot be controlled, such as interest rate risk. Management updates its evaluations regularly and reflects impairment losses in the Company's net earnings or other comprehensive income, depending on the nature of the loss, as such evaluations are revised.

The Company's derivative activities include foreign currency, interest rate and credit default swaps in variable interest entities (VIEs) that are consolidated; foreign currency swaps associated with certain senior notes and its subordinated debentures; foreign currency forwards and options used in hedging foreign exchange risk and options on interest rate swaps (or interest rate swaptions) used in hedging interest rate risk on U.S. dollar-denominated securities in Aflac Japan's portfolio; and foreign currency forwards and options used to economically hedge certain portions of forecasted cash flows denominated in yen. Inputs used to value derivatives include, but are not limited to, interest rates, credit spreads, foreign

currency forward and spot rates, and interest volatility. For derivatives associated with VIEs where it is the primary beneficiary, the Company receives valuations from a third party pricing vendor.

Deferred Policy Acquisition Costs and Policy Liabilities


Insurance premiums for most of the Company's health and life policies, including cancer, accident, hospital, critical illness, dental, vision, term life, whole life, long-term care and disability, are recognized as revenue over the premium-paying periods of the contracts when due from policyholders. When revenues are reported, the related amounts of benefits and expenses are charged against such revenues, so that profits are recognized in proportion to premium revenues during the period the policies are expected to remain in force. This association is accomplished by means of annual additions to the liability for future policy benefits and the deferral and subsequent amortization of policy acquisition costs.


Premiums from the Company's products with limited-pay features, including term life, whole life, WAYS, and child endowment, are collected over a significantly shorter period than the period over which benefits are provided. Premiums for these products are recognized as revenue over the premium-paying periods of the contracts when due from policyholders. Any gross premium in excess of the net premium is deferred and recorded in earnings, such that profits are recognized in a constant relationship with insurance in force. Benefits are recorded as an expense when they are incurred. A liability for future policy benefits is recorded when premiums are recognized using the net premium method.


Deferred Policy Acquisition Costs


The calculation of DAC and the liability for future policy benefits requires the use of estimates based on sound actuarial valuation techniques. For new policy issues, the Company reviews its actuarial assumptions and deferrable acquisition costs each year and revise them when necessary to more closely reflect recent experience and studies of actual acquisition costs. For policies in force, the Company evaluates DAC by major product groupings to determine that they are recoverable from future revenues, and any amounts determined not to be recoverable are charged against net earnings. See Note 6 of the Notes to the Consolidated Financial Statements for a detail of the DAC activity for the past two years.

The Company's policy liabilities, which are determined in accordance with applicable guidelines as defined under U.S. GAAP and Actuarial Standards of Practice, include two components that involve analysis and judgment: future policy benefits and unpaid policy claims, which accounted for 83%85% and 4% of total policy liabilities as of December 31, 2017,2019, respectively.


Future policy benefits provide for claims that will occur in the future and are generally calculated as the present value of future expected benefits to be incurred less the present value of future expected net benefit premiums. The Company calculates future policy benefits based on assumptions of morbidity, mortality, persistency and interest. These assumptions are generally established at the time a policy is issued. The assumptions used in the calculations are closely related to those used in developing the gross premiums for a policy. As required by U.S. GAAP, the Company also includes a provision for adverse deviation, which is intended to accommodate adverse fluctuations in actual experience.


Unpaid policy claims include those claims that have been incurred and are in the process of payment as well as an estimate of those claims that have been incurred but have not yet been reported to the Company. The Company computes unpaid policy claims on a non-discounted basis using statistical analyses of historical claims payments, adjusted for current trends and changed conditions. The Company updates the assumptions underlying the estimate of unpaid policy claims regularly and incorporates its historical experience as well as other data that provides information regarding the Company's outstanding liability.


The Company's insurance products provide fixed-benefit amounts per occurrence that are not subject to medical-cost inflation. Furthermore, the Company's business is widely dispersed in both the United StatesU.S. and Japan. This geographic dispersion and the nature of the Company's benefit structure mitigate the risk of a significant unexpected increase in claims payments due to epidemics and events of a catastrophic nature. Claims incurred under Aflac's policies are generally reported and paid in a relatively short time frame. The unpaid claims liability is sensitive to morbidity assumptions, in particular, severity and frequency of claims. Severity is the ultimate size of a claim, and frequency is the number of claims incurred. The Company's claims experience is primarily related to the demographics of its policyholders.


As a part of its established financial reporting and accounting practices and controls, the Company performs detailed annual actuarial reviews of its policyholder liabilities (gross premium valuation GPV, analysis) and reflects the results of those reviews in its results of operations and financial condition as required by U.S. GAAP. For Aflac Japan, the Company'sCompany’s annual reviews in 20162019 and 20152018 indicated that it neededno need to strengthen the liabilityliabilities associated with a block of care policies primarily due to low investment yields. The Company strengthened its future policy benefits liability by $52 and $18 million in 2016 and 2015, respectively, as a result of these reviews. Results of the Company’s annual review in 2017 concluded that no further strengthening was required at this time for these liabilities.Japan. For Aflac U.S., the Company's annual reviews in 2017, 20162019 and 20152018 indicated no need to strengthen liabilities associated with policies in the United States. In the U.S. and Japan, investment assumptions were reviewed in 2017 and the Company adopted expected forward rates in its GPV yield projections. In addition, in Japan, assets were allocated to blocks of business to align with yield and duration requirements of the businesses.


The table below reflects the growth of the future policy benefits liability for the years ended December 31.

The Company earns its revenues principally from insurance premiums and investments. The Company’s operating expenses primarily consist of insurance benefits provided and reserves established for anticipated future insurance benefits, general business expenses, commissions and other costs of selling and servicing its products. Profitability for the Company depends principally on its ability to price its insurance products at a level that enables the Company to earn a margin over the costs associated with providing benefits and administering those products. Profitability also depends on, among other items, actuarial and policyholder behavior experience on insurance products, and the Company's ability to attract and retain customer assets, generate and maintain favorable investment results, effectively deploy capital and utilize tax capacity, and manage expenses.


Yen–denominated income statement accounts are translated to U.S. dollars using a weighted average Japanese yen/U.S. dollar foreign exchange rate, except realized gains and losses on security transactions which are translated at the exchange rate on the trade date of each transaction. Yen–denominated balance sheet accounts are translated to U.S. dollars using a spot Japanese yen/U.S. dollar foreign exchange rate.

In computing the estimate of unpaid policy claims, the Company considers many factors, including the benefits and amounts available under the policy; the volume and demographics of the policies exposed to claims; and internal business practices, such as incurred date assignment and current claim administrative practices. The Company monitors these conditions closely and make adjustments to the liability as actual experience emerges. Claim levelsamortized hedge costs/income, which are generally stable from period to period; however, fluctuations in claim levels may occur. In calculating the unpaid policy claim liability, the Company does not calculate a range of estimates.

Other policy liabilities, which accounted for 13% of total policy liabilities as of December 31, 2017, consisted primarily of annuity and unearned premium reserves, and discounted advance premiums on deposit from policyholders in conjunction with their purchase of certain Aflac Japan insurance products. These advanced premiums are deferred upon collection and recognized as premium revenue over the contractual premium payment period. Advanced premiums represented 34% and 38% of the December 31, 2017 and 2016 other policy liabilities balances, respectively. See the Aflac Japan segment subsection of this MD&A for further information.

Income Taxes

Income tax provisions are generally based on pretax earnings reported for financial statement purposes, which differ from those amounts used in preparing the Company's income tax returns. Deferred income taxes are recognized for temporary differences between the financial reporting basis and income tax basis of assets and liabilities, based on enacted tax laws and statutory tax rates applicable to the periods in which the Company expects the temporary differences to reverse. The evaluation of a tax positioncalculated in accordance with U.S. GAAP (non-U.S. GAAP). These measures exclude items that the Company believes may obscure the underlying fundamentals and trends in the Company's insurance operations because they tend to be driven by general economic conditions and events or related to infrequent activities not directly associated with its insurance operations. The Company's management uses adjusted earnings and adjusted earnings per diluted share to evaluate the financial performance of its insurance operations on a consolidated basis, and the Company believes that a presentation of these measures is vitally important to an understanding of its underlying profitability drivers and trends of its insurance business. The Company believes that amortized hedge costs/income, which are a component of adjusted earnings, measure the periodic currency risk management costs/income related to hedging certain foreign currency exchange risks and are an important component of net investment income.

The Company defines the non-U.S. GAAP financial measures included in this filing as follows:

Adjusted earnings are the profits derived from operations.The most comparable U.S. GAAP measure is net earnings. Adjusted earnings are adjusted revenues less benefits and adjusted expenses. The adjustments to both revenues and expenses account for certain items that cannot be predicted or that are outside management’s control. Adjusted revenues are U.S. GAAP total revenues excluding realized investment gains and losses, except for amortized hedge costs/income related to foreign currency exposure management strategies and net interest cash flows from derivatives associated with certain investment strategies. Adjusted expenses are U.S. GAAP total acquisition and operating expenses including the impact of interest cash flows from derivatives associated with notes payable but excluding any nonrecurring or other items not associated with the normal course of the Company’s insurance operations and that do not reflect the Company's underlying business performance.

Adjusted earnings per share (basic or diluted) are adjusted earnings for the period divided by the weighted average outstanding shares (basic or diluted) for the period presented. The most comparable U.S. GAAP measure is net earnings per share.

Amortized hedge costs/income represent costs/income incurred or recognized in using foreign currency forward
contracts to hedge certain foreign exchange risks in the Company's Japan segment (costs) or in the Corporate and Other segment (income). These amortized hedge costs/income are derived from the difference between the foreign currency spot rate at time of trade inception and the contractual foreign currency forward rate, recognized on a straight line basis over the term of the hedge. There is no comparable U.S. GAAP financial measure for amortized hedge costs/income.

Adjusted earnings and adjusted earnings per diluted share excluding current period foreign currency impact are computed using the average yen/dollar exchange rate for the comparable prior year period, which eliminates fluctuations driven solely by yen-to-dollar currency rate changes.

Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations

Amounts excluding foreign currency impact on U.S. dollar-denominated investment income were determined using the average dollar/yen exchange rate for the comparable prior year period.

Adjusted book value is the U.S. GAAP book value (representing total shareholders' equity), less AOCI as recorded on the U.S. GAAP balance sheet. The Company considers adjusted book value important as it excludes AOCI, which fluctuates due to market movements that are outside management's control.

Adjusted return on equity (ROE) excluding foreign currency impact is calculated using adjusted earnings excluding the impact of the yen/dollar exchange rate, as reconciled with total U.S. GAAP net earnings, divided by average shareholders’ equity, excluding AOCI. The most comparable U.S. GAAP financial measure is return on average equity as determined using net earnings and average total shareholders’ equity.

Reconciling Items

Realized Investment Gains and Losses

The Company's investment strategy is more likely thanto invest primarily in fixed maturity securities to provide a reliable stream of investment income, which is one of the drivers of the Company’s growth and profitability. This investment strategy incorporates asset-liability matching (ALM) to align the expected cash flows of the portfolio to the needs of the Company's liability structure. The Company does not thatpurchase securities with the intent of generating capital gains or losses. However, investment gains and losses may be realized as a tax position will be sustained upon examination by taxing authorities. The second step is measurement, whereby a tax position that meets the more-likely-than-not recognition threshold is measured to determine the amountresult of benefit to recognizechanges in the financial statements. A valuation allowance is established for deferred tax assets when it is more likely than not that an amount will not be realized. The determinationmarkets and the creditworthiness of a valuation allowance for deferred tax assets requires management to make certain judgments and assumptions.

In evaluating the ability to recover deferred tax assets, the Company's management considers all available evidence, including taxable income in open carry back years, the existence of cumulative losses in the most recent years, forecasted earnings, future taxable income exclusive of reversing temporary differences and carryforwards, future taxable temporary difference reversals, and prudent and feasible tax planning strategies. In the event the Company determines it is not more likely than not that it will be able to realize all or part of its deferred tax assets in the future, a valuation allowance would be charged to earnings in the period such determination is made. Likewise, if it is later determined that it is more likely than not that those deferred tax assets would be realized, the previously provided valuation allowance would be reversed. Future economic conditions and market volatility, including increases in interest rates or widening credit spreads, can adversely impact the Company’sspecific issuers, tax planning strategies, and/or general portfolio management and rebalancing. The realization of investment gains and losses is independent of the underwriting and administration of the Company's insurance products. Realized investment gains and

38


Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations

losses include securities transactions, impairments, changes in particularloan loss reserves, derivative and foreign currency activities and changes in fair value of equity securities.
Securities Transactions, Impairments, and Gains (Losses) on Equity Securities

Securities transactions include gains and losses from sales and redemptions of investments where the amount received is different from the amortized cost of the investment. Impairments include other-than-temporary-impairment losses on investment securities as well as changes in loan loss reserves for loan receivables. Starting in the first quarter of 2018, gains and losses from changes in fair value of equity securities are recorded in earnings.
Certain Derivative and Foreign Currency Gains (Losses)

The Company's derivative activities include foreign currency forwards and options on certain fixed maturity securities; foreign currency forwards and options that economically hedge certain portions of forecasted cash flows denominated in yen and hedge the Company's long-term exposure to a weakening yen; foreign currency swaps associated with certain senior notes and subordinated debentures; foreign currency swaps and credit defaults swaps held in consolidated variable interest entities (VIEs); interest rate swaps used to economically hedge interest rate fluctuations in certain variable-rate investments; and interest rate swaptions to hedge changes in the fair value associated with interest rate changes for certain dollar-denominated available-for-sale securities. Gains and losses are recognized as a result of valuing these derivatives, net of the effects of hedge accounting. The Company also excludes the accounting impacts of remeasurement associated with changes in the yen/dollar exchange rate from adjusted earnings. Amortized hedge costs/ income related to certain foreign currency exposure management strategies (see Amortized Hedge Cost/Income section below), and net interest cash flows from derivatives associated with certain investment strategies and notes payable are reclassified from realized investment gains (losses) and included in adjusted earnings.

Amortized hedge costs/income can fluctuate based upon many factors, including the derivative notional amount, the length of time of the derivative contract, changes in both U.S. and Japan interest rates, and supply and demand for dollar funding. Amortized hedge costs and income have fluctuated in recent periods due to changes in the previously mentioned factors. For additional information regarding foreign currency hedging, refer to Hedging Activities in the Investments section of this MD&A.

For additional information regarding realized investment gains and losses, including details of reported amounts for the periods presented, see Notes 3 and 4 of the Notes to the Consolidated Financial Statements.

Other and Non-recurring Items

The U.S. insurance industry has a policyholder protection system that provides funds for the policyholders of insolvent insurers. The system can result in periodic charges to the Company as a result of insolvencies/bankruptcies that occur with other companies in the life insurance industry. Some states permit member insurers to recover assessments paid through full or partial premium tax offsets. These charges neither relate to the ordinary course of the Company’s abilitybusiness nor reflect the Company’s underlying business performance, but result from external situations not controlled by the Company. The Company excludes any charges associated with U.S. guaranty fund assessments and the corresponding tax benefit or expense from adjusted earnings.

In Japan, the government also requires the insurance industry to utilize tax benefitscontribute to a policyholder protection corporation that provides funds for the policyholders of insolvent insurers; however, these costs are calculated and administered differently than in the U.S. In Japan, these costs are not directly related to specific insolvencies or bankruptcies, but are rather a regular operational cost for an insurance company. Based on previously recognized capital losses. this structure, the Company does not remove the Japan policyholder protection expenses from adjusted earnings.

Nonrecurring items also include conversion costs related to legally converting the Company's Japan business to a subsidiary; these costs primarily consist of expenditures for legal, accounting, consulting, integration of systems and processes and other similar services. These Japan branch conversion costs were an immaterial amount for the year-ended December 31, 2019 and $75 million for the year-ended December 31, 2018.

Income Taxes

The Company's judgmentscombined U.S. and assumptions are subject to change given the inherent uncertaintyJapanese effective income tax rate on pretax earnings was 25.7% in predicting future performance2019 and specific industry and investment market conditions.

Interest rates and credit spreads26.7% in both the United States and Japan are not the only factors that impact the Company’s unrealized gain/loss position and the evaluation of a need for a valuation allowance on the Company’s deferred tax asset, but they do have a direct and significant effect on both. Based on its methodology described above for evaluating the need for a valuation allowance, the Company has determined that it is more likely than not that its deferred tax assets will be realized2018. The decrease in the future, therefore the Company has not recorded a valuation allowance as of December 31, 2017.

The Tax Act was signed into law on December 22, 2017. Among other things, effective January 1, 2018 the Tax Act reduced the U.S. federal statutory corporate income tax rate from 35% to 21%, eliminated or reduced certain deductions effective January 1, 2018 drove the reduction in the effective tax rate for 2019 and credits,2018.

These changes are effective on January 1, 2018. Because changes to tax rates are accounted for in the period of enactment, during the period ended December 31, 2017, the Company revalued its deferred tax assets and liabilities and recorded, as its current reasonable estimate, a net deferred tax liability reduction of $1.9 billion as of that date. While the Company believes that this estimate is reasonable, it is relying upon guidance provided by SEC Staff Accounting Bulletin No. 118 (SAB 118) that provides a measurement period of up to one year from the enactment date of December 22, 2017, in order to complete the accounting for the effects of the Tax Act. This estimate is subject to new and changing regulations, interpretations and tax guidance in the future, as well as further refinement of the Company’s calculations and changes in the interpretations and assumptions that the Company has made. As such, the estimate may change over time, possibly materially, and the Company may reduce or increase the estimated reduction of net deferred tax liability.


For additionalfurther information, on income taxsee "Critical Accounting Estimates - Income Taxes" in this MD&A, and the effects of the Tax Act during the period ended December 31, 2017, see Note 10 of the Notes to the Consolidated Financial Statements presentedfor additional information.

Foreign Currency Translation

Aflac Japan’s premiums and a significant portion of its investment income are received in yen, and its claims and most expenses are paid in yen. Aflac Japan purchases yen-denominated assets and U.S. dollar-denominated assets, which may be hedged to yen, to support yen-denominated policy liabilities. These and other yen-denominated financial statement items are, however, translated into dollars for financial reporting purposes. The Company translates Aflac Japan’s yen-denominated income statement into dollars using the average exchange rate for the reporting period, and the Company translates its yen-denominated balance sheet using the exchange rate at the end of the period.

Due to the size of Aflac Japan, whose functional currency is the Japanese yen, fluctuations in the yen/dollar exchange rate can have a significant effect on the Company's reported results. In periods when the yen weakens, translating yen into dollars results in fewer dollars being reported. When the yen strengthens, translating yen into dollars results in more dollars being reported. Consequently, yen weakening has the effect of suppressing current period results in relation to the comparable prior period, while yen strengthening has the effect of magnifying current period results in relation to the comparable prior period. Management evaluates the Company's financial performance both including and excluding the impact of foreign currency translation to monitor, respectively, cumulative currency impacts on book value and the currency-neutral operating performance over time.
RESULTS OF OPERATIONS BY SEGMENT
U.S. GAAP financial reporting requires that a company report financial and descriptive information about operating segments in its annual and interim period financial statements. Furthermore, the Company is required to report a measure of segment profit or loss, certain revenue and expense items, and segment assets. Aflac's insurance business consists of two segments: Aflac Japan and Aflac U.S. Aflac Japan is the principal contributor to consolidated earnings. Businesses that are not individually reportable, such as the Parent Company, asset management subsidiaries and business activities, including reinsurance retrocession activities are included in the Corporate and other segment. See the Item 1. Business section of this report. For information onForm 10-K for a summary of each segment's products and distribution channels, and a discussion of the conversion of Aflac Japan from a branch to a subsidiary and the creation of asset management subsidiaries in 2018. Consistent with U.S. GAAP guidance for segment reporting, pretax adjusted earnings is the Company's U.S. GAAP measure of segment performance. See Note 2 of the Notes to the Consolidated Financial Statements for the reconciliation of segment results to the Company's consolidated U.S. GAAP results and additional information.

In yen terms, Aflac Japan's net premium income decreased in 2019, primarily due to limited-pay products reaching paid-up status. Net investment income, net of amortized hedge costs, increased in 2019 primarily due to increased investments in U.S. dollar-denominated floating rate assets and $25 million of income related to a partial call of a concentrated yen-denominated exposure.

Annualized premiums in force at December 31, 2019, were ¥1.49 trillion, compared with ¥1.53 trillion in 2018. The decrease in annualized premiums in force in yen of 2.5% in 2019and 1.6% in 2018 was driven primarily by limited-pay products reaching paid up status. Annualized premiums in force, translated into dollars at respective year-end exchange rates, were $13.6 billion in 2019 and $13.8 billion in 2018.

Aflac Japan's investment portfolios include U.S. dollar-denominated securities and reverse-dual currency securities (yen-denominated debt securities with dollar coupon payments). In years when the yen strengthens in relation to the dollar, translating Aflac Japan's U.S. dollar-denominated investment income into yen lowers growth rates for net investment income, total adjusted revenues, and pretax adjusted earnings in yen terms. In years when the yen weakens, translating U.S. dollar-denominated investment income into yen magnifies growth rates for net investment income, total adjusted revenues, and pretax adjusted earnings in yen terms.
The following table illustrates the effect of translating Aflac Japan's U.S. dollar-denominated investment income and related items into yen by comparing certain segment results with those that would have been reported had dollar/yen exchange rates remained unchanged from the prior year. Amounts excluding foreign currency impact on U.S. dollar-denominated investment income, a non-U.S. GAAP financial measure, were determined using the average dollar/yen exchange rate for the comparable prior year period. See non-U.S. GAAP financial measures defined above.

In 2019, the benefit ratio decreased, compared to the prior year, primarily due to the continued change in mix of first and third sector business as first sector products become paid-up. In 2019, the adjusted expense ratio increased mainly due to lower premium income from paid-up first sector products and higher expenses for advanced technology implementation. In total for 2019, the pretax adjusted profit margin (calculated by dividing adjusted earnings by adjusted revenues) increased reflecting continued strength in benefit ratios and favorable net investment income. For 2020, the Company anticipates the Aflac Japan pretax adjusted profit margin (calculated by dividing adjusted earnings by adjusted revenues) to remain stable.

The foundation of Aflac Japan's product portfolio has been, and continues to be, third sector products, which include cancer, medical and income support insurance products. Aflac Japan has been focusing more on promotion of cancer and medical insurance products in this report.low-interest-rate environment. These products are less interest-rate sensitive and more profitable compared to first sector savings products. With continued cost pressure on Japan’s health care system, the Company expects the need for third sector products will continue to rise in the future and that the medical and cancer insurance products Aflac Japan provides will continue to be an important part of its product portfolio.


Sales of protection-type first sector and third sector products on a yen basis decreased 16.8% in 2019, compared with 2018. Earned premium growth for third and first sector protection products was 1.3%, which was consistent with the Company's expectation. The decline in sales primarily reflected reduced sales of cancer insurance through the Japan Post channel following the 2018 launch of Aflac Japan's revised cancer insurance product. In addition, the approach to refreshing the medical insurance product in 2019 took a rider versus whole policy approach. This was designed for improved economics but naturally resulted in lower reported sales. Additional factors include a change in corporate tax law, which slowed the pace of certain third sector medical products and some cancer products in both our associate channel and the bank channel, as well as increased competition from large life insurers who are increasing their focus on the third sector.

Sales of Aflac Japan cancer products in the Japan Post Group channel experienced a material decline beginning in August 2019 which has continued into 2020. For 2019, sales in the Japan Post Group channel declined by approximately 50.0% compared with 2018. The Company expects very little sales production in the Japan Post channel during the first half of 2020 and is uncertain with regard to production during the second half of the year. See the 2020 Outlook section of this MD&A for information on Aflac Japan earned premium expectations.

Independent corporate agencies and individual agencies contributed 45.7% of total new annualized premium sales for Aflac Japan in 2019, compared with 40.1% in 2018. Affiliated corporate agencies, which include Japan Post, contributed 50.0% of total new annualized premium sales in 2019, compared with 55.3% in 2018. Japan Post offers Aflac's cancer insurance products in more than 20,000 postal outlets. Notwithstanding the recent reduction in sales of Aflac Japan's cancer products in the Japan Post channel, the Company believes this alliance with Japan Post has and will benefit its cancer insurance sales over the long term. In 2019, Aflac Japan recruited 77 new sales agencies. At December 31, 2019, Aflac Japan was represented by more than 9,000 sales agencies, with more than 109,000 licensed sales associates employed by those agencies.

At December 31, 2019, Aflac Japan had agreements to sell its products at 367 banks, approximately 90% of the total number of banks in Japan. Bank channel sales accounted for 4.3% of new annualized premium sales in 2019 for Aflac Japan, compared with 4.6% in 2018.

Strategic Alliance with Japan Post Holdings

On December 19, 2018, the Parent Company and Aflac Japan entered into a Basic Agreement with Japan Post Holdings a Japanese corporation. Pursuant to the terms of the Basic Agreement, Japan Post Holdings agreed to form a capital relationship with the Parent Company, and Japan Post Holdings and Aflac Japan agreed to reconfirm existing initiatives regarding cancer insurance and to consider new joint initiatives, including leveraging digital technology in various processes, cooperation in new product development to promote customer-centric business management, cooperation in domestic and/or overseas business expansion and joint investment in third party entities and cooperation regarding asset management.

Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations

On February 28, 2019, the Parent Company entered a Shareholders Agreement with Japan Post Holdings, J&A Alliance Holdings Corporation, a Delaware corporation, solely in its capacity as trustee of J&A Alliance Trust, a New Accounting PronouncementsYork voting trust (Trust), and General Incorporated Association J&A Alliance, a Japanese general incorporated association. Pursuant to the terms of the Shareholders Agreement, the Trust will use commercially reasonable efforts to acquire, through open market or private block purchases in the U.S., beneficial ownership of approximately 7% of the outstanding shares of the Parent Company’s common stock within a period of 12 months following the date the Trust begins acquiring such stock. On May 7, 2019, a press release issued by Japan Post Holdings announced that purchases of shares of the Parent Company’s common stock commenced on April 29, 2019 through the Trust and that it planned to complete such purchases within Japan Post’s fiscal year 2019 (which ends March 31, 2020).


DuringThe Trust has agreed not to own more than 10% of the last threeParent Company’s outstanding shares for a period expiring on the earlier of four years various accounting standard-setting bodiesafter the Trust acquires 7% of such shares, five years after it acquires 5% of such shares, or ten years after the Trust begins acquiring the Parent Company’s stock. After expiration of such period, the Trust has agreed not to own more than the greater of 10% of the Parent Company’s outstanding shares or such shares representing 22.5% of the voting rights in the Parent Company.

In light of the fact that the shares acquired by the Trust, like all Aflac Incorporated common shares, will be eligible for 10-for-1 voting rights after being held for 48 consecutive months, the Shareholders Agreement further provides for voting restrictions that effectively limit the trustee’s voting rights to no more than 20% of the voting rights in the Parent Company and further restrict the trustee’s voting rights with respect to certain change in control transactions. Japan Post Holdings will not have a Board seat on the Parent Company’s Board of Directors and will not have rights to control, manage or intervene in the management of the Parent Company.

As of December 31, 2019, all regulatory approvals expressly set forth in the Shareholders Agreement have been activeobtained. The Shareholders Agreement requires the parties to use reasonable best efforts to cooperate in soliciting commentsconnection with any ongoing regulatory matters related to or arising from the Trust’s acquisition or ownership or control of the shares of Company Common Stock, including any applications or filings in connection with a direct or indirect acquisition of control of or merger with an insurer by the Company or its affiliates.

Aflac Japan Investments

The level of investment income in yen is affected by available cash flow from operations, the timing of investing the cash flow, yields on new accounting pronouncementsinvestments, the effect of yen/dollar exchange rates on U.S. dollar-denominated investment income, and other factors.

As part of the Company's portfolio management and asset allocation process, Aflac Japan invests in yen and U.S. dollar-denominated investments. Yen-denominated investments primarily consist of JGBs and public and private fixed maturity securities. Aflac Japan's U.S. dollar-denominated investments include fixed maturity investments and growth assets, including public equity securities and alternative investments in limited partnerships or similar investment vehicles. Aflac Japan has been investing in both publicly-traded and privately originated U.S. dollar-denominated investment-grade and below-investment-grade fixed maturity securities and loan receivables, and has entered into foreign currency forwards and options to hedge the currency risk on the fair value of a portion of the U.S. dollar investments.

The benefit ratio decreased in 2019, compared with 2018, primarily due to somewhat elevated lapses and a change in business mix from higher loss ratio, reserve building products to lower loss ratio, guaranteed issue products. The adjusted expense ratio increased in 2019, compared with 2018, primarily due to deferred policy acquisition costs (DAC) capitalization related to lower than anticipated sales as well as anticipated spending increases reflecting ongoing investments in the U.S. platform, distribution, and customer experience. Both the lower benefit and higher DAC amortization ratios were also impacted by increases in lapses as a result of large case volatility and replacement of an administrative partner. These items impacted persistency in the short-term but are expected to drive profitable earned premium growth in future periods. The pretax adjusted

While overall sales decreased in 2019, net earned premium increased 1.8%.
In 2019, the Aflac U.S. sales forces included an average of approximately 8,200 U.S. agents, including brokers, who were actively producing business on a weekly basis. The Company believes that this average weekly producer equivalent metric allows sales management to monitor progress and needs.

In November 2019, the Company acquired Argus Holdings, LLC and its subsidiary Argus Dental & Vision, Inc. (Argus), a benefits management organization and national network dental and vision company, which provides a platform for Aflac Dental and Vision. This transaction represents a commitment of $75 million in capital at closing and an additional $21 million in consideration paid over three years based on the achievement by Argus of certain performance targets. Tampa, Florida will serve as the home for Aflac Dental and Vision. This acquisition is a strategic entry point into the network dental and vision market and is expected to provide opportunities for sales growth, improved account penetration and distribution productivity.

Net investment income benefited from the Company’s enterprise corporate hedging program for the years ended December 31, 2019 and 2018, respectively. See the Hedging Activities subsection of this MD&A for further information on the enterprise corporate hedging program.

In December 2018, the Parent Company invested $20 million in Singapore Life Pte. Ltd. (Singapore Life), a digitally-focused life insurance company based in Singapore. The Parent Company made an additional investment of $16 million in the second quarter of 2019, bringing the total investment to $36 million. As part of the relationship, Aflac entered into a reinsurance agreement on certain protection products with Singapore Life in September 2019. However, the Company does not currently expect the equity investment or the reinsurance agreement to have a material impact on its financial position or results of operations,operations.

INVESTMENTS

The Company’s investment strategy utilizes disciplined asset and liability management while seeking long-term risk-adjusted investment returns and the delivery of stable income within regulatory and capital objectives, and preserving shareholder value. In attempting to optimally balance these objectives, the Company seeks to maintain on behalf of Aflac Japan a diversified portfolio of yen-denominated investment assets, a U.S. dollar-denominated investment portfolio hedged back to yen and a portfolio of unhedged U.S. dollar-denominated assets. As part of the Company's portfolio management and asset allocation process, Aflac U.S. invests in fixed maturity investments and growth assets, including public equity securities and alternative investments in limited partnerships. Aflac U.S. invests in both publicly traded and privately originated investment-grade and below-investment-grade fixed maturity securities and loans.

Generally, declines in fair values can be a result of changes in interest rates, yen/dollar exchange rate, and changes in net spreads driven by a broad market move or a change in the issuer's underlying credit quality. As the Company believes these issuers have the ability to continue making timely payments of principal and interest, the Company views these changes in fair value to be temporary. See the Unrealized Investment Gains and Losses section in Note 3 of the Notes to the Consolidated Financial Statements for further discussions of unrealized losses related to financial institutions and other corporate investments.
Below-Investment-Grade Securities
The Company's portfolio of below-investment-grade securities includes debt securities purchased while the issuer was rated investment grade plus other loans and bonds purchased as part of an allocation to that segment of the market. The following is the Company's below-investment-grade exposure.

(1) Securities initially purchased as investment grade, but have subsequently been downgraded to below investment grade
(2) Middle market loans are carried at amortized cost

The Company invests in senior secured bank loans and middle market loans primarily to U.S. corporate borrowers, most of which have below-investment-grade ratings. The objectives of these programs include enhancing the yield on invested assets, achieving further diversification of credit risk, and mitigating the risk of rising interest rates and hedge costs through the acquisition of floating rate assets.

The Company maintains an allocation to higher yielding corporate bonds within the Aflac Japan and Aflac U.S. portfolios. Most of these securities were rated below-investment-grade at the time of purchase, but the Company also purchased several that were rated investment grade which, because of market pricing, offer yields commensurate with below-investment-grade risk profiles. The objective of this allocation was to enhance the Company's yield on invested assets and further diversify credit risk. All investments in this program must have a minimum rating at purchase of low BB using the Company's above described rating methodology and are managed by the Company's internal credit portfolio management team.
Fixed Maturity Securities by Sector
The Company maintains diversification in investments by sector to avoid concentrations to any one sector, thus managing exposure risk. The following table shows the distribution of fixed maturities by sector classification as of December 31.

Securities by Type of Issuance
The Company has investments in both publicly and privately issued securities. The Company's ability to sell either type of security is a function of overall market liquidity which is impacted by, among other things, the amount of outstanding securities of a particular issuer or issuance, trading history of the issue or issuer, overall market conditions, and idiosyncratic events affecting the specific issue or issuer.

Aflac Japan has a portfolio of privately issued securities to better match liability characteristics and secure higher yields than those available on Japanese government or other public corporate bonds.Aflac Japan’s investments in yen-denominated privately issued securities consist primarily of non-Japanese issuers, are rated investment grade at purchase and have longer maturities, thereby allowing the Company to improve asset/liability matching and overall investment returns. These securities are generally either privately negotiated arrangements or issued under medium-term note programs and have standard documentation commensurate with credit ratings of the issuer, except when internal credit analysis indicates that additional protective and/or event-risk covenants were required. Many of these investments have protective covenants appropriate to the specific investment. These may include a prohibition of certain activities by the borrower, maintenance of certain financial measures, and specific conditions impacting the payment of the Company's notes.

HEDGING ACTIVITIES

The Company uses derivative contracts to hedge foreign currency exchange rate risk and interest rate risk. The Company uses various strategies, including derivatives, to manage these risks. See item “7A. Quantitative and Qualitative Disclosures About Market Risk” for more information about Market risk and the Company’s use of derivatives.

Derivatives are designed to reduce risk on an economic basis while minimizing the impact on financial results. The Company’s derivatives programs vary depending on the type of risk being hedged. See Note 4 of the Notes to the Consolidated Financial Statements for:

A description of the Company's derivatives, hedging strategies and underlying risk exposure.
Information about the notional amount and fair market value of the Company's derivatives.
The unrealized and realized gains and losses impact on adjusted earnings of derivatives in cash flow, fair value, net investments in foreign operations, or non-qualifying hedging relationships.

Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations

Foreign Currency Exchange Rate Risk Hedge Program

The Company has deployed the following hedging strategies to mitigate exposure to foreign currency exchange rate risk:

Aflac Japan hedges U.S. dollar-denominated investments back to yen (see Aflac Japan’s U.S. Dollar-Denominated Hedge Program below).

Aflac Japan maintains certain unhedged U.S. dollar-denominated securities, which serve as an economic currency hedge of a portion of the Company's investment in Aflac Japan (see Aflac Japan’s U.S. Dollar-Denominated Hedge Program below).

The Parent Company designates yen-denominated liabilities (notes payable and loans) as non-derivative hedging instruments and designates certain foreign currency forwards and options as derivative hedges of the Company’s net investment in Aflac Japan (see Enterprise Corporate Hedging Program below).

The Parent Company enters into forward and option contracts to accomplish a dual objective of hedging foreign currency exchange rate risk related to dividend payments by its subsidiary, ALIJ, and reducing enterprise-wide hedge costs. (see Enterprise Corporate Hedging Program below).

Aflac Japan’s U.S. Dollar-Denominated Hedge Program

Aflac Japan buys U.S. dollar-denominated investments, typically corporate bonds, and hedges them back to yen with foreign currency forwards and options to hedge foreign currency exchange rate risk. This economically creates yen assets that match yen liabilities during the life of the derivative and provides capital relief. The currency risk being hedged is generally based on fair value of hedged investments. The following table summarizes the U.S. dollar-denominated investments held by Aflac Japan as of December 31.

U.S. Dollar Program includes all U.S. dollar-denominated investments in Aflac Japan other than the investments in certain consolidated VIEs where the instrument is economically converted to yen as a result of a derivative in the consolidated variable interest entity. As of December 31, 2019, Aflac Japan had $8.8 billion outstanding notional amounts of foreign currency forwards and $21.1 billion outstanding notional amounts of foreign currency options, of which none were in-the-money, hedging the U.S. dollar-denominated investments. The fair value of Aflac Japan's unhedged U.S. dollar-denominated portfolio was $19.9 billion (excluding certain U.S. dollar-denominated assets shown in the table above as a result of consolidation that have been economically converted to yen using derivatives).

Foreign exchange derivatives used for hedging are periodically settled, which results in cash receipt or payment at maturity or early termination. The Company had net cash outflows of $20 million in 2019, net cash inflows of $272 million in

55


Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations

2018 and net cash outflows of $747 million in 2017, associated with the currency derivatives used for hedging Aflac Japan’s U.S. dollar-denominated investments.

Enterprise Corporate Hedging Program

The Company has designated certain yen-denominated liabilities and foreign currency forwards and options of the Parent Company as accounting hedges of its net investment in Aflac Japan. The Company's consolidated yen-denominated net asset position was partially hedged at $9.1 billion as of December 31, 2019, compared with $1.8 billion as of December 31, 2018.

The Company makes its accounting designation of net investment hedge at the beginning of each quarter. If the total of the designated Parent Company non-derivative and derivative notional is equal to or less than the Company's net investment in Aflac Japan, the hedge is deemed to be effective, and the currency exchange effect on the yen-denominated liabilities and the change in estimated fair value of the derivatives are reported in the unrealized foreign currency component of other comprehensive income. The Company's net investment hedge was effective during the years ended December 31, 2019 and 2018, respectively. For additional information on the Company's net investment hedging strategy, see Note 4 of the Notes to the Consolidated Financial Statements.

In order to economically mitigate risks associated with the enterprise-wide exposure to the yen and the level and volatility of hedge costs, the Parent Company enters into foreign exchange forward and option contracts. By buying U.S. dollars and selling yen, the Parent Company is effectively lowering its overall economic exposure to the yen, while Aflac Japan's U.S dollar exposure remains reduced as a result of Aflac Japan's U.S. dollar-denominated hedge program that economically creates yen assets. Among other objectives, this strategy is intended to offset the enterprise-wide amortized hedge costs by generating amortized hedge income. The portion of the enterprise-wide amortized hedge income contributed by this strategy was $89 million in 2019 and $36 million in 2018. This activity is reported in Corporate and Other. As this program evolves, the Company will continue to evaluate the program’s efficacy. See the Results of Operations section of this MD&A for the Company's definition of amortized hedge costs/income.

The following table presents metrics related to Aflac Japan amortized hedge costs and the Parent Company amortized hedge income for the years ended December 31.

Interest Rate Risk Hedge Program

Aflac Japan and Aflac U.S. use interest rate swaps to mitigate the risk of investment income volatility for certain variable-rate investments. Additionally, to manage interest rate risk associated with its U.S. dollar-denominated investments held by Aflac Japan, the Company utilizes interest rate swaptions.

For additional discussion of the risks associated with the foreign currency exposure refer to the Currency Risk section in Item 1A, specifically to the Risk Factors titled “The Company is exposed to foreign currency fluctuations in the yen/dollar exchange rate“ and “Lack of availability of acceptable yen-denominated investments could adversely affect the Company's results of operations, financial position or liquidity."

BENEFIT PLANS

Aflac Japan and Aflac U.S. have various benefit plans. For additional information on the Company's Japanese and U.S. plans, see Note 14 of the Notes to the Consolidated Financial Statements.

POLICYHOLDER PROTECTION
Policyholder Protection Corporation

The Japanese insurance industry has a policyholder protection system that provides funds for the policyholders of insolvent insurers. Legislation enacted regarding the framework of the Life Insurance Policyholder Protection Corporation (LIPPC) included government fiscal measures supporting the LIPPC. In November 2016, Japan's Diet passed legislation that again extends the government's fiscal support of the LIPPC through March 2022. Effective April 2014, the annual LIPPC contribution amount for the total life industry was lowered from ¥40 billion to ¥33 billion. Aflac Japan recognized an expense of ¥1.9 billion and ¥2.0 billion for the years ended December 31, 2019 and 2018, respectively, for LIPPC assessments.

Guaranty Fund Assessments

Under U.S. state guaranty association laws, certain insurance companies can be assessed (up to prescribed limits) for certain obligations to the policyholders and claimants of impaired or insolvent insurance companies that write the same line or similar lines of business. The amount of the guaranty fund assessment that an insurer is assessed is based on its proportionate share of premiums in that state. See Note 15 of the Notes to the Consolidated Financial Statements for further information on the assessment.

OFF-BALANCE SHEET ARRANGEMENTS

As of December 31, 2019, the Company had no material letters of credit, standby letters of credit, guarantees or standby repurchase obligations. See Note 15 of the Notes to the Consolidated Financial Statements for information on material unconditional purchase obligations that are not recorded on the Company's balance sheet.

LIQUIDITY AND CAPITAL RESOURCES
Liquidity refers to the ability to generate sufficient cash resources to meet the payment obligations of the Company. Capital refers to the long-term financial resources available to support the operations of the businesses, fund business growth and provide for an ability to withstand adverse circumstances. Financial leverage (leverage) refers to an investment strategy of using debt to increase the potential return on equity. The Company targets and actively manages liquidity, capital and leverage in the context of a number of considerations, including:

business investment and growth needs
strategic growth objectives

The governance framework supporting liquidity, capital and leverage includes global senior management and board committees that review and approve all significant capital related decisions.

The Company's cash and cash equivalents include unrestricted cash on hand, money market instruments, and other debt instruments with a maturity of 90 days or less when purchased, all of which has minimal market, settlement or other risk exposure. The target minimum amount for the Parent Company’s cash and cash equivalents is approximately $2.0 billion to provide available capital and liquidity support at the holding company.Aflac Japan and Aflac U.S. provide the primary sources of liquidity to the Parent Company through the payment of dividends and management fees. The following table presents the amounts provided to the Parent Company for the years ended December 31.

The decline in dividends during 2018 was driven by a change in the dividend regulatory approval process subsequent to the conversion of Aflac Japan from a branch to a subsidiary on April 1, 2018. The Company resumed dividend payments from Aflac Japan in the fourth quarter of 2018. Management fees decreased during 2019 and 2018, compared to prior years, due to changes in the administration of intercompany expenses between legal entities subsequent to the conversion, as well.

Prior to the Aflac Japan branch conversion, Aflac Japan paid allocated expenses and profit remittances to Aflac U.S. The following table details Aflac Japan remittances for the years ended December 31.

In 2018, the Company announced a change in its internal dividend policy which allows the Company to increase the proportion of regulatory earnings transferred from Aflac U.S. and Aflac Japan to the Parent Company. The Company intends to maintain higher than historical levels of capital and liquidity at the Parent Company with the goals of addressing the Company’s hedge costs and related potential need for collateral and mitigating against long-term weakening of the Japanese yen. Further, the Company plans to continue to maintain a portfolio of unhedged U.S. dollar based investments at Aflac Japan and consider whether the amount of such investments should be increased or decreased relative to the Company’s view of economic equity surplus in Aflac Japan in light of potentially rising hedge costs and other factors. See the "Hedging Activity" subsection in this MD&A for more information.

Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations

In addition to cash and equivalents, the Company also maintains credit facilities, both intercompany and with external partners, and a number of other available tools to support liquidity needs on a global basis. In September 2018, the Parent Company filed a shelf registration statement with the SEC that allows the Company to issue an indefinite amount of debt securities, in one or more series, from time to time until September 2021. In August 2018, the Parent Company filed a shelf registration with Japanese regulatory authorities that allows the Parent Company to conduct public offerings of bonds in Japan, including yen-denominated Samurai notes, up to ¥200 billion or its equivalent through August 2020. The shelf registration statement is for possible public offerings in Japan, but the bonds issued under the shelf may be transferred by the bondholders to U.S. persons in compliance with U.S. law. The Company believes outside sources for additional debt and equity capital, if needed, will continue to be available. Additionally, as of December 31, 2019, the Parent Company and Aflac had four lines of credit with third parties and three intercompany lines of credit. For additional information, see Note 9 of the Notes to the Consolidated Financial Statements.

The primary uses of cash by the Parent Company are shareholder dividends, the repurchase of its common stock and interest on its outstanding indebtedness and operating expenses.

Liabilities for unrecognized tax benefits in the amount of $17 have been excluded from the tabular disclosure above because the timing of cash payment is not reasonably estimable.
(1)Liability amounts are those reported on the consolidated balance sheet as of December 31, 2019.
(2)The estimated payments due by period reflect future estimated cash payments to be made to policyholders and others for future policy benefits. These projected cash outflows are based on assumptions for future policy persistency, mortality, morbidity, and other assumptions comparable with the Company's experience, consider future premium receipts on current policies in force, and assume market growth and interest crediting consistent with assumptions used in amortizing deferred acquisition costs. These cash outflows are undiscounted with respect to interest and, as a result, the sum of the cash outflows shown for all years in the table of $244,884 exceeds the corresponding liability amount of $90,335. The Company has made significant assumptions to determine the future estimated cash outflows related to the underlying policies and contracts. Due to the significance of the assumptions used, actual cash outflow amounts and timing will differ, possibly materially, from these estimates.
(3)Includes assumptions as to the timing of policyholders reporting claims for prior periods and the amount of those claims. Actual amounts and timing of unpaid policy claims payments may differ significantly from the estimates above.

For more information on the Company's major contractual obligations, see the applicable Note in the Notes to the Consolidated Financial Statements as indicated in the line items in the table above.

The Company's financial statements convey its financing arrangements during the periods presented. The Company has not engaged in material intra-period short-term financings during the periods presented that are not otherwise reported in its balance sheet or disclosed therein. The Company was in compliance with all of the covenants of its notes payable and lines of credit at December 31, 2019. The Company has not entered into transactions involving the transfer of financial assets with an obligation to repurchase financial assets that have been accounted for as a sale under applicable accounting standards,

including securities lending transactions. See Notes 1, 3, and 4 of the Notes to the Consolidated Financial Statements for more information on the Company's securities lending and derivative activities. With the exception of disclosed activities in those referenced footnotes and the Risk Factors entitled, "The Company is exposed to foreign currency fluctuations in the yen/dollar exchange rate" and "Lack of availability of acceptable yen-denominated investments could adversely affect the Company's results of operations, financial position or liquidity," the Company is not aware of a trend, demand, commitment, event or uncertainty that would likely result in its liquidity increasing or decreasing by a material amount.
Consolidated Cash Flows

The Company translates cash flows for Aflac Japan's yen-denominated items into U.S. dollars using weighted-average exchange rates. In years when the yen weakens, translating yen into dollars causes fewer dollars to be reported. When the yen strengthens, translating yen into dollars causes more dollars to be reported.

Operating Activities
The principal cash inflows for the Company's insurance activities come from insurance premiums and investment income. The principal cash outflows are the result of policy claims, operating expenses, income tax, as well as interest expense. As a result of policyholder aging, claims payments are expected to gradually increase over the life of a policy. Therefore, future policy benefit reserves are accumulated in the early years of a policy and are designed to help fund future claims payments.
The Company expects its future cash flows from premiums and its investment portfolio to be sufficient to meet its cash needs for benefits and expenses. Consolidated cash flow from operations decreased 9.3% in 2019, compared with 2018.
Investing Activities
The Company's investment objectives provide for liquidity primarily through the purchase of publicly traded investment-grade debt securities. Prudent portfolio management dictates that the Company attempts to match the duration of its assets with the duration of its liabilities. Currently, when the Company's fixed maturity securities mature, the proceeds may be reinvested at a yield below that required for the accretion of policy benefit liabilities on policies issued in earlier years. However, the long-term nature of the Company's business and its strong cash flows provide the Company with the ability to minimize the effect of mismatched durations and/or yields identified by various asset adequacy analyses. From time to time or when market opportunities arise, the Company disposes of selected fixed maturity securities that are available for sale to improve the duration matching of assets and liabilities, improve future investment yields, and/or re-balance its portfolio. As a result, dispositions before maturity can vary significantly from year to year.

As part of its overall corporate strategy, the Company has announced an increase in its commitment to the Aflac Ventures Fund from $250 million to $400 million, as opportunities emerge. These investments are included in equity securities or the other investments line in the consolidated balance sheets. The Aflac Ventures Fund is a subsidiary of Aflac Corporate Ventures which is reported in the Corporate and other segment. The central mission of Aflac Corporate Ventures is to support the organic growth and business development needs of Aflac Japan and Aflac U.S. with emphasis on digital applications designed to improve the customer experience, gain efficiencies, and develop new markets in an effort to enhance and defend long-term shareholder value.

As part of an arrangement with Federal Home Loan Bank of Atlanta (FHLB), Aflac U.S. obtains low-cost funding from FHLB supported by acceptable forms of collateral pledged by Aflac U.S. Aflac U.S. borrowed and repaid $217 million under this program during 2019. As of December 31, 2019, Aflac U.S. had outstanding borrowings of $403 million reported in its balance sheet.

Financing Activities

Consolidated cash used by financing activities was $1.7 billion in 2019 and $1.6 billion in 2018.

In December 2019, the Parent Company issued four series of senior notes totaling ¥38.0 billion through a public debt offering under its U.S. shelf registration statement. The first series, which totaled ¥12.6 billion, bears interest at a fixed rate of .500% per annum, payable semi-annually, and will mature in December 2029. The second series, which totaled ¥9.3 billion, bears interest at a fixed rate of .843% per annum, payable semi-annually, and will mature in December 2031. The third series, which totaled ¥9.8 billion, bears interest at a fixed rate of .934% per annum, payable semi-annually, and will mature in December 2034. The fourth series, which totaled ¥6.3 billion, bears interest at a fixed rate of 1.122% per annum, payable semi-annually, and will mature in December 2039. These notes may only be redeemed before maturity, in whole but not in part, upon the occurrence of certain changes affecting U.S. taxation, as specified in the indenture governing the terms of the issuance.

In September 2019, the Parent Company renewed a ¥30.0 billion senior term loan facility. The first tranche of the facility, which totaled ¥5.0 billion, bears interest at a rate per annum equal to the Tokyo interbank market rate (TIBOR), or alternate TIBOR, if applicable, plus the applicable TIBOR margin and will mature in September 2026. The applicable margin ranges between .30% and .70%, depending on the Parent Company's debt ratings as of the date of determination. The second tranche, which totaled ¥25.0 billion, bears interest at a rate per annum equal to the TIBOR, or alternate TIBOR, if applicable, plus the applicable TIBOR margin and will mature in September 2029. The applicable margin ranges between .45% and 1.00%, depending on the Parent Company's debt ratings as of the date of determination.

In April 2019, ALIJ issued ¥30.0 billion (par value) of perpetual subordinated bonds. These bonds bear interest at a fixed rate of .963% per annum and then at six-month Euro Yen LIBOR plus an applicable spread on and after the day immediately following April 18, 2024. The bonds will be callable on each interest payment date on and after April 18, 2024. In November 2019, ALIJ amended the bonds to change their duration from perpetual to a stated maturity date of April 16, 2049 and to remove provisions that permitted ALIJ to defer payments of interest under certain circumstances.

In October 2018, the Parent Company issued $550 million of senior notes through a U.S. public debt offering. The notes bear interest at a fixed rate of 4.750% per annum, payable semi-annually, and will mature in January 2049. These notes are redeemable at the Parent Company's option in whole at any time or in part from time to time at a redemption price equal to the greater of: (i) the aggregate principal amount of the notes to be redeemed or (ii) the amount equal to the sum of the present values of the remaining scheduled payments for principal of and interest on the notes to be redeemed, not including any portion of the payments of interest accrued as of such redemption date, discounted to such redemption date on a semiannual basis at the yield to maturity for a U.S.Treasury security with a maturity comparable to the remaining term of the notes, plus 25 basis points, plus in each case, accrued and unpaid interest on the principal amount of the notes to be redeemed to, but excluding, such redemption date.

In October 2018, the Parent Company issued three series of senior notes totaling ¥53.4 billion through a public debt offering under its U.S. shelf registration statement. The first series, which totaled ¥29.3 billion, bears interest at a fixed rate of 1.159% per annum, payable semi-annually, and will mature in October 2030. The second series, which totaled ¥15.2 billion, bears interest at a fixed rate of 1.488% per annum, payable semi-annually, and will mature in October 2033. The third series, which totaled ¥8.9 billion, bears interest at a fixed rate of 1.750% per annum, payable semi-annually, and will mature in October 2038. These notes may only be redeemed before maturity, in whole but not in part, upon the occurrence of certain changes affecting U.S. taxation, as specified in the indenture governing the terms of the issuance.

In November 2018, the Parent Company used the net proceeds from the October 2018 issuance of its senior notes to redeem $550 million of the Parent Company's 2.40% senior notes due in 2020.

See Note 9 of the Notes to the Consolidated Financial Statements for further information on the debt issuances discussed above.

The Company was in compliance with all of the covenants of its notes payable and lines of credit at December 31, 2019.

Cash returned to shareholders through treasury stock purchases and dividends was $2.4 billion in 2019, compared with $2.1 billion in 2018.

The following tables present a summary of treasury stock activity during the years ended December 31.

Under share repurchase authorizations from the Company's board of directors, the Company purchased 32.0 million shares of its common stock in 2019, compared with 28.9 million shares in 2018. As of December 31, 2019, a remaining balance of 37.1 million shares of the Company's common stock was available for purchase under share repurchase authorizations by its board of directors. The Company currently plans to repurchase $1.3 billion to $1.7 billion of its common stock in 2020, assuming stable capital conditions and absent compelling alternatives. See Note 11 of the Notes to the Consolidated Financial Statements for additional information.

Cash dividends paid to shareholders in 2019 of $1.08 per share increased 3.8% over 2018. The following table presents the dividend activity for the years ended December 31.

Regulatory Restrictions

Aflac, CAIC and TOIC are domiciled in Nebraska and are subject to its regulations. Subsequent to the Japan branch conversion to a subsidiary, Aflac Japan is domiciled in Japan and subject to local regulations. The Nebraska Department of Insurance imposes certain limitations and restrictions on payments of dividends, management fees, loans and advances to the Parent Company. Under Nebraska insurance law, prior approval of the Nebraska Department of Insurance is required for dividend distributions that exceed the greater of the net income from operations, which excludes net realized investment gains, for the previous year determined under statutory accounting principles, or 10% of statutory capital and surplus as of the previous year-end. In addition, the Nebraska insurance department must approve service arrangements and other transactions within the affiliated group of companies. These regulatory limitations are not expected to affect the level of management fees or dividends paid to the Parent Company. (See below for discussion of restrictions imposed by Japanese insurance regulators.) A life insurance company’s statutory capital and surplus is determined according to rules prescribed by the NAIC, as modified by the insurance department in the insurance company’s state of domicile. Statutory accounting rules are different from U.S. GAAP and are intended to emphasize policyholder protection and company solvency. Similar laws apply in New York, the domiciliary jurisdiction of Aflac New York.


62


Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations

The continued long-term growth of the Company's business may require increases in the statutory capital and surplus of its insurance operations. Aflac’s insurance operations may secure additional statutory capital through various sources, such as internally generated statutory earnings, capital contributions by the Parent Company from funds generated through debt or equity offerings, or reinsurance transactions. The NAIC’s RBC formula is used by insurance regulators to help identify inadequately capitalized insurance companies. The RBC formula quantifies insurance risk, business risk, asset risk and interest rate risk by weighing the types and mixtures of risks inherent in the insurer’s operations.

Aflac's company action level RBC ratio was 539% as of December 31, 2019, compared with 560% at December 31, 2018. Aflac’s RBC ratio remains high and reflects a strong capital and surplus position. As of December 31, 2019, Aflac's total adjusted capital of $2.2 billion exceeded the company action level required capital and surplus of $.4 billion by $1.8 billion. With the announcement of the Japan branch conversion to a subsidiary, we had announced our intention to remove excess capital out of Aflac, targeting a 500% RBC by the end of 2019. As of December 31, 2019, the Company has completed the RBC drawdown plan and has moved $1.75 billion of capital from Aflac to the Parent Company, supporting the Company's capital deployment and risk management activities.

The maximum amount of dividends that can be paid to the Parent Company by Aflac, CAIC and TOIC without prior approval of Nebraska's director of insurance is the greater of the net income from operations, which excludes net realized investment gains, for the previous year determined under statutory accounting principles, or 10% of statutory capital and surplus as of the previous year-end. Dividends declared by Aflac during 2020 in excess of $864 million would be considered extraordinary and require such approval. Following the Japan branch conversion to a subsidiary, the Company used extraordinary dividends as needed to actively manage to appropriate RBC levels that are lower yet sufficient to maintain ratings and support prudent capital management. Similar laws apply in New York, the domiciliary jurisdiction of Aflac New York. See Note 13 of the Notes to the Consolidated Financial Statements for information regarding the impact of permitted practices by the Nebraska Department of Insurance on the Company's statutory capital and surplus.

The NAIC considers its Solvency Modernization Initiative (SMI) process relating to updating the U.S. insurance solvency regulation framework to be ongoing. The SMI has focused on key issues such as capital requirements, governance and risk management, group supervision, reinsurance, statutory accounting and financial reporting matters. Many of these key issues have been finalized and/or are near completion; however, the NAIC still has some ongoing initiatives related to SMI, such as monitoring the international efforts on group capital requirements as well as RBC.In addition, the NAIC is also considering changes to investment risk factors. Any negative developments by the NAIC in these areas could result in increased capital requirements for the Company.

Aflac is subject to the NAIC’s Own Risk and Solvency Assessment (ORSA). Through the ORSA requirements, Aflac is expected to regularly, no less than annually, conduct an ORSA to assess the adequacy of its risk management framework, and its current and estimated projected future solvency position; internally document the process and results of the assessment; and provide a confidential high-level ORSA Summary Report annually to the lead state commissioner if the insurer is a member of an insurance group. In November 2019, Aflac filed its ORSA report with the Nebraska Department of Insurance.

In addition to limitations and restrictions imposed by U.S. insurance regulators, after the Japan branch conversion on April 1, 2018, the new Japan subsidiary is required to meet certain financial criteria as governed by Japanese corporate law in order to provide dividends to the Parent Company. Under these criteria, dividend capacity at the Japan subsidiary is basically defined as total equity excluding common stock, accumulated other comprehensive income amounts, capital reserves (representing statutorily required amounts in Japan) but reduced for net after-tax unrealized losses on available-for-sale securities. These dividend capacity requirements are generally aligned with the SMR. Japan's FSA maintains its own solvency standard which is quantified through the SMR. Aflac Japan's SMR is sensitive to interest rate, credit spread, and foreign exchange rate changes, therefore the Company continues to evaluate alternatives for reducing this sensitivity. In the event of a rapid change in market risk conditions causing SMR to decline, the Company has one senior unsecured revolving credit facility in the amount of ¥100 billion and a committed reinsurance facility in the amount of approximately ¥110 billion as a capital contingency plan. Additionally, the Company could take action to enter into derivatives on unhedged U.S. dollar-denominated investments with foreign currency options or forwards. See Notes 8 and 9 of the Notes to the Consolidated Financial Statements for additional information.

The Company has already undertaken various measures to mitigate the sensitivity of Aflac Japan's SMR. For example, the Company employs policy reserve matching (PRM) investment strategies, which is a Japan-specific accounting treatment that reduces SMR interest rate sensitivity since PRM-designated investments are carried at amortized cost consistent with corresponding liabilities. In order for a PRM-designated asset to be held at amortized cost, there are certain criteria that must be maintained. The primary criteria relates to maintaining the duration of designated assets and liabilities within a specified tolerance range. If the duration difference is not maintained within the specified range without rebalancing, then a certain

63


Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations

portion of the assets must be re-classified as available for sale and held at fair value with any associated unrealized gain or loss recorded in surplus. To rebalance, assets may need to be sold in order to maintain the duration with the specified range, resulting in realizing a gain or loss from the sale. For U.S. GAAP, PRM investments are categorized as available for sale. The Company also uses foreign currency derivatives to hedge a portion of its U.S. dollar-denominated investments.(See Notes 3, 4 and 8 of the Notes to the Consolidated Financial Statements for additional information on the Company's investment strategies, hedging activities, and reinsurance, respectively.)

Aflac's SMR ratio remains high and reflects a strong capital and surplus position. As of December 31, 2019, Aflac Japan's SMR was 1,043%, compared with 965% at December 31, 2018. As part of the conversion of Aflac Japan from a branch to a subsidiary on April 1, 2018, the Company experienced an accounting-driven decline in the SMR of approximately 130 points, compared with the SMR as of December 31, 2017. The Company expects to be able to pay dividends out of certain accounts, thus restoring this accounting impact over an estimated three-year period.

The FSA has been conducting field testing with the insurance industry concerning the introduction of an economic value-based solvency regime. The field testing will assist the FSA in determining if an economic value-based solvency regime in Japan will be appropriate for the insurance industry.

Privacy and Cybersecurity Governance

The Company’s Board of Directors has adopted an information security policy directing management to establish and operate a global information security program with the goals of monitoring existing and emerging threats and ensuring that the Company’s information assets and data, and the data of its customers, are appropriately protected from loss or theft. The Board has delegated oversight of the Company’s information security program to the Audit and Risk Committee. The Company’s senior officers, including its Global Security and Chief Information Security Officer, are responsible for the operation of the global information security program and regularly communicate with the Audit and Risk Committee on the program, including with respect to the state of the program, compliance with applicable regulations, current and evolving threats, and recommendations for changes in the information security program. The global information security program also includes a cybersecurity incident response plan that is designed to provide a management framework across Company functions for a coordinated assessment and response to potential security incidents. This framework establishes a protocol to report certain incidents to the Global Security and Chief Information Security Officer and other senior officers, with the goal of timely assessing such incidents, determining applicable disclosure requirements and communicating with the Audit and Risk Committee. The incident response plan directs the executive officers to report certain incidents immediately and directly to the Lead Non-Management Director.

Additional Information

Investors should note that the Company announces material financial information in its SEC filings, press releases and public conference calls. In accordance with SEC guidance, the Company may also use the Investor Relations section of the Company's website (http://investors.aflac.com) to communicate with investors about the Company. It is possible that the financial and other information the Company posts there could be deemed to be material information. The information on the Company's website is not part of this document. Further, the Company's references to website URLs are intended to be inactive textual references only.

CRITICAL ACCOUNTING ESTIMATES

The Company prepares its financial statements in accordance with U.S. GAAP. These principles are established primarily by the FASB. In this MD&A, references to U.S. GAAP issued by the FASB are derived from the FASB Accounting Standards Codification™ (ASC). The preparation of financial statements in conformity with U.S. GAAP requires the Company to make estimates based on currently available information when recording transactions resulting from business operations. The estimates that the Company deems to be most critical to an understanding of Aflac’s results of operations and financial condition are those related to the valuation of investments and derivatives, DAC, liabilities for future policy benefits and unpaid policy claims, and income taxes. The preparation and evaluation of these critical accounting estimates involve the use of various assumptions developed from management’s analyses and judgments. The application of these critical accounting estimates determines the values at which 94% of the Company's assets and 81% of its liabilities are reported as

64


Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations

of December 31, 2019, and thus has a direct effect on net earnings and shareholders' equity. Subsequent experience or use of other assumptions could produce significantly different results.

Valuation of Investments, Including Derivatives, and Recognition of Other-than-Temporary Impairments

Aflac's investments, primarily consisting of debt and equity securities, include both publicly issued and privately issued securities. For publicly issued securities, the Company determines the fair values from quoted market prices readily available from public exchange markets and price quotes and valuations from third party pricing vendors. For the majority of privately issued securities within the Company's investment portfolio, a third party pricing vendor has developed valuation models that the Company utilizes to determine fair values. For the remaining privately issued securities, the Company uses non-binding price quotes from outside brokers.

The Company estimates the fair values of its securities on a monthly basis. The Company monitors the estimated fair values obtained from its pricing vendors and brokers for consistency from month to month, while considering current market conditions. The Company also periodically discusses with its pricing brokers and vendors the pricing techniques they use to monitor the consistency of their approach and periodically assess the appropriateness of the valuation level assigned to the values obtained from them. If a fair value appears unreasonable, the Company will re-examine the inputs and assess the reasonableness of the pricing data with the vendor. Additionally, the Company may compare the inputs to relevant market indices and other performance measurements. Based on management's analysis, the valuation is confirmed or may be revised if there is evidence of a more appropriate estimate of fair value based on available market data. The Company has performed verification of the inputs and calculations in any valuation models to confirm that the valuations represent reasonable estimates of fair value. Inputs used to value derivatives include, but are not limited to, interest rates, credit spreads, foreign currency forward and spot rates, and interest volatility.

The Company routinely reviews its investments that have experienced declines in fair value to determine if the decline is other than temporary. The identification of distressed investments, the determination of fair value if not publicly traded and the assessment of whether a decline is other than temporary involve significant management judgment. The Company must apply considerable judgment in determining the likelihood of the security recovering in value while the Company owns it. Factors that may influence this include the Company's assessment of the issuer’s ability to continue making timely payments of interest and principal, the overall level of interest rates and credit spreads, and other factors. This process requires consideration of risks, which can be controlled to a certain extent, such as credit risk, and risks which cannot be controlled, such as interest rate risk. Management updates its evaluations regularly and reflects impairment losses in the Company's net earnings or other comprehensive income, depending on the nature of the loss, as such evaluations are revised.

Deferred Policy Acquisition Costs and Policy Liabilities

Insurance premiums for most of the Company's health and life policies, including cancer, accident, hospital, critical illness, dental, vision, term life, whole life, long-term care and disability, are recognized as revenue over the premium-paying periods of the contracts when due from policyholders. When revenues are reported, the related amounts of benefits and expenses are charged against such revenues, so that profits are recognized in proportion to premium revenues during the period the policies are expected to remain in force. This association is accomplished by means of annual additions to the liability for future policy benefits and the deferral and subsequent amortization of policy acquisition costs.

Premiums from the Company's products with limited-pay features, including term life, whole life, WAYS, and child endowment, are collected over a significantly shorter period than the period over which benefits are provided. Premiums for these products are recognized as revenue over the premium-paying periods of the contracts when due from policyholders. Any gross premium in excess of the net premium is deferred and recorded in earnings, such that profits are recognized in a constant relationship with insurance in force. Benefits are recorded as an expense when they are incurred. A liability for future policy benefits is recorded when premiums are recognized using the net premium method.

Deferred Policy Acquisition Costs

The calculation of DAC and the liability for future policy benefits requires the use of estimates based on sound actuarial valuation techniques. For new policy issues, the Company reviews its actuarial assumptions and deferrable acquisition costs each year and revise them when necessary to more closely reflect recent experience and studies of actual acquisition costs. For policies in force, the Company evaluates DAC by major product groupings to determine that they are recoverable from future revenues, and any amounts determined not to be recoverable are charged against net earnings. See Note 6 of the Notes to the Consolidated Financial Statements for a detail of the DAC activity for the past two years.

Policy Liabilities

The Company's policy liabilities, which are determined in accordance with applicable guidelines as defined under U.S. GAAP and Actuarial Standards of Practice, include two components that involve analysis and judgment: future policy benefits and unpaid policy claims, which accounted for 85% and 4% of total policy liabilities as of December 31, 2019, respectively.

Future policy benefits provide for claims that will occur in the future and are generally calculated as the present value of future expected benefits to be incurred less the present value of future expected net benefit premiums. The Company calculates future policy benefits based on assumptions of morbidity, mortality, persistency and interest. These assumptions are generally established at the time a policy is issued. The assumptions used in the calculations are closely related to those used in developing the gross premiums for a policy. As required by U.S. GAAP, the Company also includes a provision for adverse deviation, which is intended to accommodate adverse fluctuations in actual experience.

Unpaid policy claims include those claims that have been incurred and are in the process of payment as well as an estimate of those claims that have been incurred but have not yet been reported to the Company. The Company computes unpaid policy claims on a non-discounted basis using statistical analyses of historical claims payments, adjusted for current trends and changed conditions. The Company updates the assumptions underlying the estimate of unpaid policy claims regularly and incorporates its historical experience as well as other data that provides information regarding the Company's outstanding liability.

The Company's insurance products provide fixed-benefit amounts per occurrence that are not subject to medical-cost inflation. Furthermore, the Company's business is widely dispersed in both the U.S. and Japan. This geographic dispersion and the nature of the Company's benefit structure mitigate the risk of a significant unexpected increase in claims payments due to epidemics and events of a catastrophic nature. Claims incurred under Aflac's policies are generally reported and paid in a relatively short time frame. The unpaid claims liability is sensitive to morbidity assumptions, in particular, severity and frequency of claims. Severity is the ultimate size of a claim, and frequency is the number of claims incurred. The Company's claims experience is primarily related to the demographics of its policyholders.

As a part of its established financial reporting and accounting practices and controls, the Company performs detailed annual actuarial reviews of its policyholder liabilities (gross premium valuation analysis) and reflects the results of those reviews in its results of operations and financial condition as required by U.S. GAAP. For Aflac Japan, the Company’s annual reviews in 2019 and 2018 indicated no need to strengthen liabilities associated with policies in Japan. For Aflac U.S., the Company's annual reviews in 2019 and 2018 indicated no need to strengthen liabilities associated with policies in the U.S.

The table below reflects the growth of the future policy benefits liability for the years ended December 31.

RESULTS OF OPERATIONS

The Company earns its revenues principally from insurance premiums and investments. The Company’s operating expenses primarily consist of insurance benefits provided and reserves established for anticipated future insurance benefits, general business expenses, commissions and other costs of selling and servicing its products. Profitability for the Company depends principally on its ability to price its insurance products at a level that enables the Company to earn a margin over the costs associated with providing benefits and administering those products. Profitability also depends on, among other items, actuarial and policyholder behavior experience on insurance products, and the Company's ability to attract and retain customer assets, generate and maintain favorable investment results, effectively deploy capital and utilize tax capacity, and manage expenses.

Yen–denominated income statement accounts are translated to U.S. dollars using a weighted average Japanese yen/U.S. dollar foreign exchange rate, except realized gains and losses on security transactions which are translated at the exchange rate on the trade date of each transaction. Yen–denominated balance sheet accounts are translated to U.S. dollars using a spot Japanese yen/U.S. dollar foreign exchange rate.

The following discussion includes references to the Company's performance measures, operatingadjusted earnings, operatingadjusted earnings per diluted share, and amortized hedge costs,costs/income, which are not calculated in accordance with U.S. GAAP.GAAP (non-U.S. GAAP). These measures exclude items that the Company believes may obscure the underlying fundamentals and trends in the Company's insurance operations because they tend to be driven by general economic conditions and events or related to infrequent activities not directly associated with its insurance operations. The Company's management uses operatingadjusted earnings and operatingadjusted earnings per diluted share to evaluate the financial performance of its insurance operations on a consolidated basis, and the Company believes that a presentation of these measures is vitally important to an understanding of its underlying profitability drivers and trends of its insurance business. The Company believes that amortized hedge costs,costs/income, which are a component of operatingadjusted earnings, measure the periodic currency risk management costs associated withcosts/income related to hedging a portion of Aflac Japan’s U.S. dollar-denominated investmentscertain foreign currency exchange risks and are an important component of net investment income.


AflacThe Company defines operating earnings (athe non-U.S. GAAP financial measure)measures included in this filing as follows:

Adjusted earnings are the profits derived from operations. Operatingoperations.The most comparable U.S. GAAP measure is net earnings. Adjusted earnings includes interest cash flows associated with notes payableare adjusted revenues less benefits and amortized hedge costs relatedadjusted expenses. The adjustments to foreign currency denominated investments, but excludesboth revenues and expenses account for certain items that cannot be predicted or that are outside of management's control, such asmanagement’s control. Adjusted revenues are U.S. GAAP total revenues excluding realized investment gains and losses, from securities transactions, impairments, change in loan loss reserves and certain derivative andexcept for amortized hedge costs/income related to foreign currency activities;exposure management strategies and net interest cash flows from derivatives associated with certain investment strategies. Adjusted expenses are U.S. GAAP total acquisition and operating expenses including the impact of interest cash flows from derivatives associated with notes payable but excluding any nonrecurring items; andor other non-operating income (loss) from net earnings. Nonrecurring and other non-operating items consist of infrequent events and activity not associated with the normal course of the Company’s insurance operations and that do not reflect Aflac’sthe Company's underlying business performance. The Company defines operating

This change will only pertain to the label of the hedge. There is no comparable U.S. GAAP financial measure and will not alter its definition or calculation.for amortized hedge costs/income.


Because a significant portion of the Company's business is conducted in Japan and foreign exchange rates are outside of management’s control, the Company believes it is important to understand the impact of translating Japanese yen into U.S. dollars. OperatingAdjusted earnings and operatingadjusted earnings per diluted share excluding current period foreign currency impact are computed using the average yen/dollar exchange rate for the comparable prior year period, which

Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations

Amounts excluding foreign currency impact on U.S. dollar-denominated investment income were determined using the average dollar/yen exchange rate for the comparable prior year period.

Adjusted book value is the U.S. GAAP book value (representing total shareholders' equity), less AOCI as recorded on the U.S. GAAP balance sheet. The Company considers adjusted book value important as it excludes AOCI, which fluctuates due to market movements that are outside management's control.

Adjusted return on equity (ROE) excluding foreign currency impact is calculated using adjusted earnings excluding the impact of the yen/dollar exchange rate, as reconciled with total U.S. GAAP net earnings, divided by average shareholders’ equity, excluding AOCI. The most comparable U.S. GAAP financial measure is return on average equity as determined using net earnings and average total shareholders’ equity.

The following table is a reconciliation of items impacting operatingadjusted earnings and operatingadjusted earnings per diluted share to the most directly comparable U.S. GAAP measures of net earnings and net earnings per diluted share, respectively, for the years ended December 31.

Reconciling Items

Realized Investment Gains and Losses


The Company's investment strategy is to invest primarily in fixed-maturityfixed maturity securities to provide a reliable stream of investment income, which is one of the drivers of the Company’s growth and profitability. This investment strategy incorporates asset-liability matching (ALM) to align the expected cash flows of the portfolio to the needs of the Company's liability structure. The Company does not purchase securities with the intent of generating capital gains or losses. However, investment gains and losses may be realized as a result of changes in the financial markets and the creditworthiness of specific issuers, tax planning strategies, and/or general portfolio management and rebalancing. The realization of investment gains and losses is independent of the underwriting and administration of the Company's insurance products. Realized investment gains and

Securities Transactions, Impairments, and ImpairmentsGains (Losses) on Equity Securities


Securities transactions include gains and losses from sales and redemptions of investments where the amount received is different from the amortized cost of the investment. Impairments include other-than-temporary-impairment losses on investment securities as well as changes in loan loss reserves for loan receivables.

Starting in the first quarter of 2018, gains and losses from changes in fair value of equity securities are recorded in earnings.
Certain Derivative and Foreign Currency Gains (Losses)


The Company's derivative activities include foreign currency forwards and options interest rate swaptions and futures on certain fixed-maturityfixed maturity securities; foreign currency forwards and options that economically hedge certain portions of forecasted cash flows denominated in yen and hedge the Company's long-term exposure to a weakening yen; foreign currency swaps associated with certain senior notes and subordinated debentures; and foreign currency swaps and credit defaults swaps held in consolidated variable interest entities (VIEs).; interest rate swaps used to economically hedge interest rate fluctuations in certain variable-rate investments; and interest rate swaptions to hedge changes in the fair value associated with interest rate changes for certain dollar-denominated available-for-sale securities.

Hedge Costs

Effective January 1, 2017, operating earnings includes the impact of amortized hedge costs. Amortized hedge costs represent costs incurred in using foreign currency forward contracts to hedge the foreign exchange risk of a portion of U.S. dollar-denominated assets in the Company's Japan segment investment portfolio. These amortized hedge costs are derived from the difference between the foreign currency spot rate at time of trade inception and the contractual foreign currency forward rate, recognized on a straight line basis over the term of the hedge. There is no comparable U.S. GAAP financial measure for amortized hedge costs. Prior year operating earnings have been revised to conform to this change. Beginning in 2016, the Company changed its non-U.S. GAAP reporting for these hedge costs by amortizing them evenly over the life of the foreign currency forward contracts. In 2016, the Company began increasing the duration of the foreign currency forward contracts used to hedge its U.S. dollar-denominated assets in Aflac Japan's investment portfolio to cover periods extending beyond one year. Therefore, recognizing these costs over the extended hedging periods provides a better measure of the Company's costs, and better reflects the economics of how hedge costs emerge over the life of the hedge.

Hedge costscosts/income can fluctuate based upon many factors, including the derivative notional amount, the length of time of the derivative contract, changes in both U.S. and Japan interest rates, and supply and demand for U.S. dollar funding. HedgeAmortized hedge costs and income have increasedfluctuated in recent periods due to changes in the previously mentioned factors. In late 2017, the Company took steps to mitigate rising hedge costs by increasing the amount of unhedged U.S. dollar-denominated investments held in Aflac Japan and to reduce hedge cost volatility by extending hedge duration. For additional information regarding foreign currency hedging, refer to the Hedging Activities in the Investments section below.of this MD&A.


For additional information regarding realized investment gains and losses, including details of reported amounts for the periods presented, see Notes 3 and 4 of the Notes to the Consolidated Financial Statements.


Other and Non-recurring Items


The United StatesU.S. insurance industry has a policyholder protection system that provides funds for the policyholders of insolvent insurers. The system can result in periodic charges to the Company as a result of insolvencies/bankruptcies that occur with other companies in the life insurance industry. Some states permit member insurers to recover assessments paid through full or partial premium tax offsets. These charges neither relate to the ordinary course of the Company’s business nor reflect the Company’s underlying business performance, but result from external situations not controlled by the Company.

Based on the underlying nature of these assessments, effective January 1, 2017, the The Company adopted a policy of excludingexcludes any charges associated with U.S. guaranty fund assessments and the corresponding tax benefit or expense from operatingadjusted earnings.


ForIn Japan, the Penn Treaty liquidationgovernment also requires the insurance industry to contribute to a policyholder protection corporation that was recognized by judicial authorityprovides funds for the policyholders of insolvent insurers; however, these costs are calculated and administered differently than in March 2017,the U.S. In Japan, these costs are not directly related to specific insolvencies or bankruptcies, but are rather a regular operational cost for an insurance company. Based on this structure, the Company estimated and recognized a discounted liability for assessments of $62 million (undiscounted $94 million), offset by discounted premium tax credits of $48 million (undiscounted $74 million), for a net $14 million impact to net income indoes not remove the quarter ended March 31, 2017. Other guaranty fund assessments for the year ended December 31, 2017 were immaterial. For additional information regarding guaranty fund assessments, see Note 15 of the Notes to the Consolidated Financial Statements.Japan policyholder protection expenses from adjusted earnings.


Effective January 1, 2017, nonrecurringNonrecurring items also include conversion costs related to legally converting the Company's Japan branchbusiness to a subsidiary; these costs primarily consist of expenditures for legal, accounting, consulting, integration of systems and processes and other similar services. These Japan branch conversion costs amounted to $42were an immaterial amount for the year-ended December 31, 2019 and $75 million for the year endedyear-ended December 31, 2017.2018.

The Company includes the accounting impacts of remeasurement associated with changesCompany's combined U.S. and Japanese effective income tax rate on pretax earnings was 25.7% in the yen/dollar exchange rate as an other non-operating item. During 2016, the Company recognized a foreign currency gain of $109 million due to a temporary sizable U.S. dollar cash balance2019 and cash settlements of U.S. dollar-denominated investment transactions within the Japan segment.

26.7% in 2018. The Company considers the costs associated with the early redemption of its debt to be unrelated to the underlying fundamentals and trendsdecrease in its insurance operations. Additionally, these costs are driven by changes in interest rates subsequent to the issuance of the debt, and the Company considers these interest rate changes to represent economic conditions not directly associated with its insurance operations. In November 2017, the Parent Company extinguished $500 million of its 5.50% subordinated debentures. The pretax non-operating expense due to the early redemption of these notes was $13 million. In 2016, the Parent Company completed a tender offer in which it extinguished $176 million principal of its 6.90% senior notes due 2039 and $193 million principal of its 6.45% senior notes due 2040. The pretax non-operating loss due to the early redemption of these notes was $137 million. During 2015, the make-whole premium paid to the investors of the Company's 8.50% fixed-rate senior notes for the early redemption of those notes was recorded as a $230 million pretax non-operating loss.

Tax Reform Adjustment

Among other changes, the Tax Act reduced the U.S. federal statutory corporate income tax rate from 35% to 21% effective January 1, 2018. Because changes to tax rates are accounted for2018 drove the reduction in the period of enactment, the Company recognized a non-recurring estimated $1.9effective tax rate for 2019 and 2018. Total income taxes were $1.1 billion benefit in the three-month periodboth 2019 and full year ended December 31, 2017. While the Company believes that this estimate is reasonable, it is relying upon guidance provided by SEC Staff Accounting Bulletin No. 118 that provides a measurement period of up to one year from the enactment date of December 22, 2017 in order2018.

Foreign Currency Translation

Aflac Japan’s premiums and a significant portion of its investment income are received in yen, and its claims and most expenses are paid in yen. Aflac Japan purchases yen-denominated assets and U.S. dollar-denominated assets, which may be hedged to yen, to support yen-denominated policy liabilities. These and other yen-denominated financial statement items are, however, translated into dollars for financial reporting purposes. The Company translates Aflac Japan’s yen-denominated income statement into dollars using the average exchange rate for the reporting period, and the Company translates its yen-denominated balance sheet using the exchange rate at the end of the period.

Due to the size of Aflac Japan, whose functional currency is the Japanese yen, fluctuations in the yen/dollar exchange rate can have a significant effect on the Company's reported results. In periods when the yen weakens, translating yen into dollars results in fewer dollars being reported. When the yen strengthens, translating yen into dollars results in more dollars being reported. Consequently, yen weakening has the effect of suppressing current period results in relation to the comparable prior period, while yen strengthening has the effect of magnifying current period results in relation to the comparable prior period. Management evaluates the Company's financial performance both including and excluding the impact of foreign currency translation to monitor, respectively, cumulative currency impacts on book value and the currency-neutral operating performance over time.

Income Taxes

The Company's combined U.S. and Japanese effective income tax rate on pretax earnings was (14.6)% in 2017, 34.6% in 2016 and 34.4% in 2015. The reduction in the tax rate for 2017 was primarily due to a $1.9 billion benefit as a result of the Tax Act. The impact of the Tax Act, including the Company's combined U.S. and Japanese effective income tax rate, may be adjusted in future periods due to, among other things, further refinement of the Company's calculations, changes in interpretations and assumptions the Company has made, tax guidance that may be issued and actions the Company may take as a result of the Tax Act. The Company also benefited from a $24 million favorable resolution of uncertain tax positions in 2017 related to tax years that closed, in addition to benefits associated with filing amended tax returns and the adoption of new accounting guidance related to stock compensation.Total income taxes were $(586) million in 2017, compared with $1.4 billion in 2016 and $1.3 billion in 2015. Japanese income taxes on Aflac Japan's results account for most of the Company's consolidated income tax expense. For further information, see Critical Accounting Estimates - Income Taxes above in this MD&A, and Note 10 of the Notes to the Consolidated Financial Statements for additional information.

2018 Outlook

The Company's objective in 2018 is to maintain its strong capital position while producing stable earnings and strong cash flows. The Company believes that its market-leading position, powerful brand recognition and diverse distribution in Japan and the United States will provide support toward this objective.

The U.S. tax reforms enacted in December 2017 provided Aflac with an opportunity to accelerate and increase its investments in initiatives that reflect the Company's values and objectives. The Company expects to increase overall investment in the U.S. by approximately $250 million over the next three to five years. These strategic investments target continued growth in the Company's U.S. operations, investments in technology and digital businesses, commitments to the Company's philanthropic efforts, and employee training programs and expanded employee benefits, including both an enhanced 401(k) matching program and additional Company-paid Aflac policies.

The Company has projected an effective tax rate of 26.5% for 2018, derived from Japan’s corporate tax rate of 28%, the U.S. rate of 21%, and assuming a stable mix of earnings.

While the Company has faced a challenging interest rate environment, particularly in Japan, it will continue to monitor these and other economic conditions as the Company executes on its plans for sales, investments and capital management. The Company believes that its efforts will support its prudent strategies for capital deployment, as well as its ongoing commitment to customer service, product innovation and distribution enhancement.

INSURANCERESULTS OF OPERATIONS
Aflac's insurance business consists of two segments: Aflac Japan and Aflac U.S. Aflac Japan, which operates as a branch of Aflac, is the principal contributor to consolidated earnings. Operating business segments that are not individually reportable and business activities, including reinsurance retrocession activities, not included in Aflac Japan or Aflac U.S. are included in the "Other business segments" category.

On December 2, 2016, the Company publicly announced that it will pursue the conversion of Aflac Japan from a branch structure to a subsidiary structure, with the subsidiary incorporated as a “Kabushiki Kaisha.” While the branch structure remains an acceptable legal form, the subsidiary structure has emerged as the more prevalent structure for both domestic and foreign companies operating in Japan. In addition, emerging global regulatory standards generally favor the subsidiary structure for foreign insurance and financial service companies. The adoption of this new organizational framework is expected to be tax-neutral and not to have a material impact on the daily operations of either Aflac Japan or Aflac U.S. as a result of this conversion. In addition, the Company expects to obtain enhanced flexibility in capital management and business development as a result of the conversion. The Company anticipates completion of the conversion as early as April 1, 2018.

BY SEGMENT
U.S. GAAP financial reporting requires that a company report financial and descriptive information about operating segments in its annual and interim period financial statements. Furthermore, the Company is required to report a measure of segment profit or loss, certain revenue and expense items, and segment assets.

Businesses that are not individually reportable, such as the Parent Company, evaluates its sales efforts using new annualized premium sales, an industry operating measure. New annualized premium sales, which include both new salesasset management subsidiaries and business activities, including reinsurance retrocession activities are included in the Corporate and other segment. See the Item 1. Business section of this Form 10-K for a summary of each segment's products and distribution channels, and a discussion of the conversion of Aflac Japan from a branch to a subsidiary and the incremental increasecreation of asset management subsidiaries in premiums due2018.

Annualized premiums in force at December 31, 2017,2019, were 1.55¥1.49 trillion, yen, compared with 1.61¥1.53 trillion yen in 2016 and 1.62 trillion yen in 2015.2018.

Annualized premiums in force, translated into dollars at respective year-end exchange rates, were $13.7$13.6 billion in 2017,2019 and $13.8 billion in 2016, and $13.4 billion in 2015.2018.


Aflac Japan's investment portfolios include U.S. dollar-denominated securities and reverse-dual currency securities (yen-denominated debt securities with dollar coupon payments). In years when the yen strengthens in relation to the dollar, translating Aflac Japan's U.S. dollar-denominated investment income into yen lowers growth rates for net investment income, total operatingadjusted revenues, and pretax operatingadjusted earnings in yen terms. In years when the yen weakens, translating U.S. dollar-denominated investment income into yen magnifies growth rates for net investment income, total operatingadjusted revenues, and pretax operatingadjusted earnings in yen terms.

The following table illustrates the effect of translating Aflac Japan's U.S. dollar-denominated investment income and related items into yen by comparing certain segment results with those that would have been reported had yen/dollardollar/yen exchange rates remained unchanged from the prior year.

The foundation of Aflac Japan's product portfolio has been, and continues to be, third sector products, which include cancer, medical and Income Supportincome support insurance products. Sales of third sector products on a yen basis increased 4.1% during 2017, compared with 2016. Aflac Japan has been focusing more on promotion of cancer and medical insurance products in this low-interest-rate environment. These products are less interest-rate sensitive and more profitable compared to first sector savings products. With continued cost pressure on Japan’s health care system, the Company expects the need for third sector products will continue to rise in the future and that the medical and cancer insurance products Aflac Japan provides will continue to be an important part of its product portfolio.


AsSales of protection-type first sector and third sector products on a resultyen basis decreased 16.8% in 2019, compared with 2018. Earned premium growth for third and first sector protection products was 1.3%, which was consistent with the Company's expectation. The decline in sales primarily reflected reduced sales of cancer insurance through the Japan Post channel following the 2018 launch of Aflac Japan's revised cancer insurance product. In addition, the approach to refreshing the medical insurance product in 2019 took a rider versus whole policy approach. This was designed for improved economics but naturally resulted in lower reported sales. Additional factors include a change in corporate tax law, which slowed the pace of certain third sector medical products and some cancer products in both our associate channel and the bank channel, as well as increased competition from large life insurers who are increasing their focus on the third sector.

Sales of Aflac Japan cancer products in the Japan Post Group channel experienced a material decline beginning in August 2019 which has continued into 2020. For 2019, sales in the Japan Post Group channel declined by approximately 50.0% compared with 2018. The Company expects very little sales production in the Japan Post channel during the first half of 2020 and is uncertain with regard to production during the second half of the interest rate policy in Japan,year. See the 2020 Outlook section of this MD&A for information on Aflac Japan has taken significant actions to limit sales of certain first sector products, including WAYS and child endowment. First sector product sales were down 75.0% in 2017 compared with 2016, reflecting the Company's actions to reduce the sale of first sector savings products that are more interest-sensitive. Aflac Japan's focus will remain on less interest-sensitive third sector products.earned premium expectations.

Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations

On February 28, 2019, the Parent Company entered a Shareholders Agreement with Japan Post Holdings, J&A Alliance Holdings Corporation, a Delaware corporation, solely in its capacity as trustee of J&A Alliance Trust, a New York voting trust (Trust), and General Incorporated Association J&A Alliance, a Japanese general incorporated association. Pursuant to the terms of the Shareholders Agreement, the Trust will use commercially reasonable efforts to acquire, through open market or private block purchases in the U.S., beneficial ownership of approximately 7% of the outstanding shares of the Parent Company’s common stock within a period of 12 months following the date the Trust begins acquiring such stock. On May 7, 2019, a press release issued by Japan Post Holdings announced that purchases of shares of the Parent Company’s common stock commenced on April 29, 2019 through the Trust and that it planned to complete such purchases within Japan Post’s fiscal year 2019 (which ends March 31, 2020).

The Trust has agreed not to own more than 10% of the Parent Company’s outstanding shares for a period expiring on the earlier of four years after the Trust acquires 7% of such shares, five years after it acquires 5% of such shares, or ten years after the Trust begins acquiring the Parent Company’s stock. After expiration of such period, the Trust has agreed not to own more than the greater of 10% of the Parent Company’s outstanding shares or such shares representing 22.5% of the voting rights in the Parent Company.

In light of the fact that the shares acquired by the Trust, like all Aflac Incorporated common shares, will be eligible for 10-for-1 voting rights after being held for 48 consecutive months, the Shareholders Agreement further provides for voting restrictions that effectively limit the trustee’s voting rights to no more than 20% of the voting rights in the Parent Company and further restrict the trustee’s voting rights with respect to certain change in control transactions. Japan Post Holdings will not have a Board seat on the Parent Company’s Board of Directors and will not have rights to control, manage or intervene in the management of the Parent Company.

As of December 31, 2019, all regulatory approvals expressly set forth in the Shareholders Agreement have been obtained. The Shareholders Agreement requires the parties to use reasonable best efforts to cooperate in connection with any ongoing regulatory matters related to or arising from the Trust’s acquisition or ownership or control of the shares of Company Common Stock, including any applications or filings in connection with a direct or indirect acquisition of control of or merger with an insurer by the Company or its affiliates. The foregoing is subject to and qualified in its entirety by reference to the full text of the Shareholders Agreement, a copy of which is attached as Exhibit 10.50 to the Company’s Quarterly Report on Form 10-Q filed April 26, 2019, and the terms of which exhibit are incorporated herein by reference.

On January 1, 2016, the company revised its definition of purchases to include the reinvestment of proceeds related to unplanned sale activity. New purchases include all purchases related to fixed maturities and perpetuals, loan receivables, and equities. Securities lending/repurchase agreement activity and capital contributions to alternatives are excluded. The definition of new money yield has also been revised to reflect this change. Yields for equities are based on the assumed dividend yield at the time of purchase.


The increase in the Aflac Japan new money yield in 20172019 was primarily due to increases in yen interest rates during much of the investment period as well as increaseddecreased allocations to higherlower yielding yen-denominated asset classes.

In 2017,2019, the Aflac U.S. sales forces included an average of more than 8,800approximately 8,200 U.S. agents, including brokers, who were actively producing business on a weekly basis. The Company believes that this average weekly producer equivalent metric allows sales management to monitor progress and needs.


One Day PaySM In November 2019, the Company acquired Argus Holdings, LLC and its subsidiary Argus Dental & Vision, Inc. (Argus), a benefits management organization and national network dental and vision company, which provides a platform for Aflac Dental and Vision. This transaction represents a commitment of $75 million in capital at closing and an additional $21 million in consideration paid over three years based on the achievement by Argus of certain performance targets. Tampa, Florida will serve as the home for Aflac Dental and Vision. This acquisition is a claims initiative that Aflac U.S. has focused on to process, approvestrategic entry point into the network dental and pay eligible claims in just one day. The Company believes that this claims practice enhances the Aflac U.S. brand reputationvision market and the trust policyholders have in Aflac, and it helps Aflac stand out from competitors.

Aflac U.S. products provide cash benefits that can be used to help with increasing out-of-pocket medical expenses, help cover household costs, or protect against income and asset loss. Group products and relationships with insurance brokers that handle the larger-case market are helping Aflac U.S. expand its reach selling to larger businesses. Aflac U.S. is regularly evaluating the marketplace to identify opportunities to bring the most relevant, cost-effective products to customers. The Company believes the need for its products remains very strong, and Aflac U.S. continues to work on enhancing its distribution capabilities to access employers of all sizes, including initiatives that benefit the field force and the broker community. At the same time, the Company is seeking opportunities to leverage its brand strength and attractive product portfolio in the evolving health care environment.

U.S. Regulatory Environment

Healthcare Reform Legislation

The Affordable Care Act (ACA), federal health care legislation, was intended to give Americans of all ages and income levels access to comprehensive major medical health insurance and gave the U.S. federal government direct regulatory authority over the business of health insurance. While the ACA was enacted in 2010, the major elements of the law became effective on January 1, 2014. The ACA included major changes to the U.S. health care insurance marketplace. Among other changes, the ACA included an individual medical insurance coverage mandate (which has since been repealed effective 2019 by the Tax Act), provided for penalties on certain employers for failing to provide adequate coverage, created health insurance exchanges, and addressed coverage and exclusions as well as medical loss ratios. It also imposed an excise tax on certain high cost plans, known as the “Cadillac tax,” that is currently scheduled to begin in 2020. The ACA also included changes in government reimbursements and tax credits for individuals and employers and altered federal and state regulation of health insurers. The ACA, as enacted, does not require material changes in the design of the Company's insurance products. However, indirect consequences of the legislation and regulations could present challenges that could potentially have an impact on the Company's sales model, financial condition and results of operations. The United States Congress has considered and may continue to consider legislation that would repeal and replace key provisions of the ACA. There can be no assurance that any legislation affecting the ACA will be passed by Congress, nor as to the ultimate timing or provisions of any such legislation, nor as to the effect of any such legislation on the design or marketability of the Company's insurance products.

President Trump signed an Executive Order in October 2017 directing federal regulatory agencies to review and modify certain regulations issued under the ACA. The stated objectives of the Executive Order are to increase competition and consumer choices in health care markets, and to lower costs for health care, by making association health plans available to more employers, allowing employers to make better use of health reimbursement arrangements, and expanding coverage through short-term insurance. The Executive Order tasks three federal agencies, the Departments of Labor (DOL), Treasury, and Health and Human Services (HHS) with reviewing current rules and developing guidance to implement the order. While the details of any proposed modifications will not be known until further action by the agencies, the Company anticipates that the Executive Order will not have a significant impact on the availability or marketability of its products.

Tax Reform Legislation

The Tax Act was signed into law on December 22, 2017. Among other things, effective January 1, 2018, the Tax Act reduced the U.S. federal statutory corporate income tax rate from 35% to 21%, eliminated or reduced certain deductions and credits and limited the deductibility of interest expense and executive compensation.

The Tax Act also transitions international corporate taxation from a worldwide system to a modified territorial system, which in light of the current tax treatment of Aflac Japan as a branch has the effect of subjecting the earnings of Aflac

54



Japan to Japan taxation and subjecting the Company's other earnings, including the consolidated earnings of the Parent Company, to U.S. taxation. The treatment of Aflac Japan as a branch for U.S. tax purposes is not expected to change upon the completion of its conversion from a branch structure to a subsidiary structure for legal purposes, which conversion is currently anticipated to be completed as early as April 1, 2018.

Aflac U.S. prices its business on an internal rate of return basis. The Aflac U.S. business has a financial structure that the Company expects to be neutral on a pricing basis from these tax changes. The Aflac U.S. products have high initial costs for marketing, underwriting and administration, which will have less tax relief under the changes and will increase the amount required to invest in new business. In addition, the Company expects that RBC requirements will increase on an after-tax basis, being another source of initial funding required for these products. The tax basis for reserves and DAC may also change the timing of tax payments in an accelerated or unfavorable direction. All of these effects will offset a favorable lower tax rate on income in later years. The overall impact is expected to be neutral on a pricing basis from these various effects.

The Tax Act changes are effective on January 1, 2018. However, because changes to tax rates are accountedprovide opportunities for in the period of enactment, during the period ended December 31, 2017, the Company revalued its deferred tax assetssales growth, improved account penetration and liabilities and recorded, as its current reasonable estimate, a net deferred tax liability reduction of $1.9 billion as of that date. For information on the effects of the Tax Act during the period ended December 31, 2017, see Note 10 of the Notes to the Consolidated Financial Statements presented in this report. For information on the conversion of Aflac Japan from a branch to a subsidiary, see General Business under Item 1, Business, in this report.

Dodd-Frank Act

Title VII of the Dodd-Frank Act and regulations issued thereunder, in particular rules to require central clearing for certain types of derivatives, may have an impact on Aflac's derivative activity, including activity on behalf of Aflac Japan. In addition, in 2015 and 2016, six U.S. financial regulators, including the U.S. Commodity Futures Trading Commission (CFTC), issued final rules regarding the exchange of initial margin (IM) and variation margin (VM) for uncleared swaps that impose greater obligations on swap dealers regarding uncleared swaps with certain counterparties, such as Aflac. The requirements of such rules with respect to VM, as well as similar regulations in Europe, became effective on March 1, 2017. Full compliance with respect to all counterparties was required by September 1, 2017. The requirements of such rules with respect to IM are currently being phased in and will be fully implemented by September 1, 2020. In October of 2017, the CFTC and the European Commission each finalized comparability determinations that permit certain swap dealers who are subject to both regulatory margin regimes to take advantage of substituted compliance by complying with one set of margin requirements. The margin requirements are expected to result in more stringent collateral requirements and to affect other aspects of Aflac's derivatives activity.

The Dodd-Frank Act also established a Federal Insurance Office (FIO) under the U.S. Treasury Department to monitor all aspects of the insurance industry and of lines of business other than certain health insurance, certain long-term care insurance and crop insurance. Traditionally, U.S. insurance companies have been regulated primarily by state insurance departments. The FIO does not directly regulate the insurance industry, but under Dodd-Frank it has the power to preempt state insurance regulations that are inconsistent with international agreements reached by the federal government, subject to certain requirements and restrictions. In December 2013, the FIO released a report entitled "How To Modernize And Improve The System Of Insurance Regulation In The United States." The report was required by the Dodd-Frank Act, and included 18 recommended areas of near-term reform for the states, including addressing capital adequacy and safety/soundness issues, reform of insurer resolution practices, and reform of marketplace regulation. The report also listed nine recommended areas for direct federal involvement in insurance regulation. Some of the recommendations outlined in the FIO report released in December 2013 have been implemented. The National Association of Registered Agents and Brokers Reform Act, signed into law in January 2015, simplifies the agent and broker licensing process across state lines. The FIO has also engaged with the supervisory colleges to monitor financial stability and identify regulatory gaps for large national and internationally active insurers. The new presidential administration in the United States and Congress have stated proposals to reform or repeal certain provisions of the Dodd-Frank Act, some of which have been implemented. The Company cannot predict with any degree of certainty what impact, if any, such proposals will have on Aflac's business, financial condition, or results of operations.

Insurance Guaranty Laws

Under state insurance guaranty association laws and similar laws in international jurisdictions, Aflac is subject to assessments, based on the share of business it writes in the relevant jurisdiction, for certain obligations of insolvent insurance companies to policyholders and claimants. In the United States, some states permit member insurers to recover

55



assessments paid through full or partial premium tax offsets. The Company's policy is to accrue assessments when the entity for which the insolvency relates has met its state of domicile's statutory definition of insolvency, the amount of the loss is reasonably estimable and the related premium upon which the assessment is based is written. In most states, the definition is met with a declaration of financial insolvency by a court of competent jurisdiction.

* Investment grade at respective reporting date
(1) Securities initially purchased as investment grade, but have subsequently been downgraded to below investment grade
(2) Middle market loans are carried at amortized cost


The Company invests in senior secured bank loans and middle market loans primarily to U.S. corporate borrowers, most of which have below-investment-grade ratings. The bank loan and middle market loan investment programs are managed externally by third party firms specializing in this asset class and require a minimum average portfolio rating of low BB and a minimum single investment rating of low B from one of the NRSROs. The objectives of these programs include enhancing the yield on invested assets, achieving further diversification of credit risk, and mitigating the risk of rising interest rates and hedge costs through the acquisition of floating rate assets.


60




The Company maintains an allocation to higher yielding corporate bonds within the Aflac Japan and Aflac U.S. portfolios. Most of these securities were rated below-investment-grade at the time of purchase, but the Company also purchased several that were rated investment grade which, because of market pricing, offer yields commensurate with below-investment-grade risk profiles. The objective of this allocation was to enhance the Company's yield on invested assets and further diversify credit risk. All investments in this program must have a minimum rating at purchase of low BB using the Company's above described rating methodology and are managed by the Company's internal credit portfolio management team.

Fixed Maturity Securities by Sector
The Company maintains diversification in investments by sector to avoid concentrations to any one sector, thus managing exposure risk. The following table shows the distribution of fixed maturities by sector classification as of December 31.

Securities by Type of Issuance
The Company has investments in both publicly and privately issued securities. The Company's ability to sell either type of security is a function of overall market liquidity which is impacted by, among other things, the amount of outstanding securities of a particular issuer or issuance, trading history of the issue or issuer, overall market conditions, and idiosyncratic events affecting the specific issue or issuer.

(2) Excludes Rule 144A securities starting in the first quarter of 2019

The perpetual securities the Company holds were largely issued by banks that are integral to the financial markets of the sovereign country of the issuer. As a result of the issuer's position within the economy of the sovereign country, the Company's perpetual securities may be subject to a higher risk of nationalization of their issuers in connection with capital injections from an issuer's sovereign government. The Company cannot be assured that such capital support will extend to all levels of an issuer's capital structure. In addition, certain governments or regulators may consider imposing interest and principal payment restrictions on issuers of hybrid securities to preserve cash and preserve the issuer's capital. Beyond the cash flow impact that additional deferrals would have on the Company's portfolio, such deferrals could result in ratings downgrades of the affected securities, which in turn could result in a reduction of fair value of the securities and increase the Company's regulatory capital requirements. The Company considers these factors in its credit review process.

Aflac Japan has a portfolio of privately issued securities to better match liability characteristics and secure higher yields than those available on Japanese government or other public corporate bonds.Aflac Japan’s investments in yen-denominated privately issued securities consist primarily of non-Japanese issuers, are rated investment grade at purchase and have longer maturities, thereby allowing the Company to improve asset/liability matching and overall investment returns. These securities are generally either privately negotiated arrangements or issued under medium-term note programs and have standard documentation commensurate with credit ratings of the issuer, except when internal credit analysis indicates that additional protective and/or event-risk covenants were required. Many of these investments have protective covenants appropriate to the specific investment. These may include a prohibition of certain activities by the borrower, maintenance of certain financial measures, and specific conditions impacting the payment of the Company's notes.


Hedging ActivitiesHEDGING ACTIVITIES


The Company uses derivative contracts to hedge foreign currency exchange rate risk and interest rate risk. The Company uses various strategies, including derivatives, to manage these risks. See item “7A. Quantitative and Qualitative Disclosures About Market Risk” for more information about Market risk and the Company’s use of derivatives.

Derivatives are designed to reduce risk on an economic basis while minimizing the impact on financial results. The Company’s derivatives programs vary depending on the type of risk being hedged. See Note 4 of the Notes to the Consolidated Financial Statements for:

A description of the Company's derivatives, hedging strategies and underlying risk exposure.
Information about the notional amount and fair market value of the Company's derivatives.
The unrealized and realized gains and losses impact on adjusted earnings of derivatives in cash flow, fair value, net investments in foreign operations, or non-qualifying hedging relationships.

Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations

Foreign Currency Exchange Rate Risk Hedge Program

The Company has deployed the following hedging strategies to mitigate exposure to foreign currency exchange rate risk:

Aflac Japan hedges U.S. dollar-denominated investments back to yen (see Aflac Japan’s U.S. Dollar-Denominated Hedge Program below).

Aflac Japan maintains certain unhedged U.S. dollar-denominated securities, which serve as an economic currency hedge of a portion of the Company's investment in Aflac Japan (see Aflac Japan’s U.S. Dollar-Denominated Hedge Program below).

The Parent Company designates yen-denominated liabilities (notes payable and loans) as non-derivative hedging instruments and designates certain foreign currency forwards and options as derivative hedges of the Company’s net investment in Aflac Japan (see Enterprise Corporate Hedging Program below).

The Parent Company enters into forward and option contracts to accomplish a dual objective of hedging foreign currency exchange rate risk related to dividend payments by its subsidiary, ALIJ, and reducing enterprise-wide hedge costs. (see Enterprise Corporate Hedging Program below).

Aflac Japan’s U.S. Dollar-Denominated InvestmentsHedge Program


Most of Aflac Japan's cash, investments, and liabilities are yen-denominated. However, Aflac Japan also ownsbuys U.S. dollar-denominated investments, a portion of which Aflac Japantypically corporate bonds, and hedges them back to yen with foreign currency forwards and options.options to hedge foreign currency exchange rate risk. This economically creates yen assets that match yen liabilities during the life of the derivative and provides capital relief. The currency risk being hedged is generally based on fair value of hedged investments.investments. The following charttable summarizes the U.S. dollar-denominated investments held by Aflac Japan as of December 31.

U.S. Dollar Program includes all U.S. dollar-denominated investments in Aflac Japan other than the investments in certain consolidated VIEs where the instrument is economically converted to yen as a result of a derivative in the consolidated variable interest entity. As of December 31, 2017,2019, Aflac Japan had $9.3$8.8 billion outstanding notional amounts of foreign currency forwards and $8.4$21.1 billion outstanding notional amounts of foreign currency options, of which none were in-the-money, hedging the U.S. dollar-denominated investments, resulting in the unhedgedinvestments.

Net Investment Hedge

The Company's investment in Aflac Japan is affected by changes in the yen/dollar exchange rate. To mitigate this exposure, the Company has taken several courses of action. First, Aflac Japan maintains certain unhedged U.S. dollar-denominated securities, which serve as an economic currency hedge of a portion of the Company's investment in Aflac Japan. Second, the Company has designated the majority of the Parent Company’scertain yen-denominated liabilities (notes payable and loans) as non-derivative hedging instruments and certain foreign currency forwards and options of the Parent Company as derivativeaccounting hedges of the Company'sits net investment in Aflac Japan. The Company's consolidated yen-denominated net asset position was partially hedged at $9.1 billion as of December 31, 2019, compared with $1.8 billion as of December 31, 2018.

The Company makes its accounting designation of net investment hedge at the beginning of each quarter. If the total of the designated Parent Company non-derivative and derivative notional is equal to or less than the Company's net investment in Aflac Japan, the hedge is deemed to be effective, and the currency exchange effect on the yen-denominated liabilities and the change in estimated fair value of the derivatives are reported in the unrealized foreign currency component of other comprehensive income. The Company's net investment hedge was effective during the years ended December 31, 2017, 20162019 and 2015,2018, respectively.

For the hedge ofadditional information on the Company's net investment hedging strategy, see Note 4 of the Notes to the Consolidated Financial Statements.

In order to economically mitigate risks associated with the enterprise-wide exposure to the yen and the level and volatility of hedge costs, the Parent Company enters into foreign exchange forward and option contracts. By buying U.S. dollars and selling yen, the Parent Company is effectively lowering its overall economic exposure to the yen, while Aflac Japan's U.S dollar exposure remains reduced as a result of Aflac Japan's U.S. dollar-denominated hedge program that economically creates yen assets. Among other objectives, this strategy is intended to offset the enterprise-wide amortized hedge costs by generating amortized hedge income. The portion of the enterprise-wide amortized hedge income contributed by this strategy was $89 million in 2019 and $36 million in 2018. This activity is reported in Corporate and Other. As this program evolves, the Company will continue to evaluate the program’s efficacy. See the Results of Operations section of this MD&A for the Company's definition of amortized hedge costs/income.

The following table presents metrics related to Aflac Japan the Company has designated certain ofamortized hedge costs and the Parent Company's yen-denominated liabilities and foreign currency forwards and options as accounting hedges of its net investment in Aflac Japan. The Company's consolidated yen-denominated net asset position was partially hedged at $1.8 billion as of December 31, 2017, with hedging instruments comprised of $1.4 billion of yen-denominated debt and $.4 billion of foreign currency forwards and options, compared with aCompany amortized hedge of $1.3 billion as of December 31, 2016, with hedging instruments comprised of $.3 billion of yen-denominated debt and $1.0 billion of foreign currency forwards and options.

Interest Rate Risk Hedge Program

Aflac Japan and Aflac U.S. use interest rate swaps to mitigate the risk of investment income volatility for hedging purposes differs fromcertain variable-rate investments. Additionally, to manage interest rate risk associated with its U.S. dollar-denominated investments held by Aflac Japan, the yen-denominated net asset position as discussed inCompany utilizes interest rate swaptions.

For additional discussion of the risks associated with the foreign currency exposure refer to the Currency Risk subsection ofsection in Item 7A. As disclosed in that section,1A, specifically to the consolidation of the underlying assets in certain VIEs requires that theRisk Factors titled “The Company derecognize its yen-denominated investment in the VIE and recognize the underlying fixed-maturity or perpetual securities and cross-currency swaps. While these U.S. dollar investments will createis exposed to foreign currency fluctuations in the combinationyen/dollar exchange rate“ and “Lack of availability of acceptable yen-denominated investments could adversely affect the U.S. dollar-denominated investment and the cross-currencyCompany's results of operations, financial position or liquidity."

swap economically creates a yen-denominated investment that qualifies for inclusion as a component of the Company's investment in Aflac Japan. Similarly, the combination of the U.S. corporate bonds and the foreign currency forwards and options that the Company has entered into economically creates a yen-denominated investment that qualifies for inclusion as a component of the Company's investment in Aflac Japan.

BENEFIT PLANS

Aflac Japan and Aflac U.S. have various benefit plans. For additional information on the Company's Japanese and U.S. plans, see Note 14 of the Notes to the Consolidated Financial Statements.

POLICYHOLDER PROTECTION
Policyholder Protection Corporation

The Japanese insurance industry has a policyholder protection system that provides funds for the policyholders of insolvent insurers. Legislation enacted regarding the framework of the Life Insurance Policyholder Protection Corporation (LIPPC) included government fiscal measures supporting the LIPPC. In November 2016, Japan's Diet passed legislation that again extends the government's fiscal support of the LIPPC through March 2022. Effective April 2014, the annual LIPPC contribution amount for the total life industry was lowered from ¥40 billion to ¥33 billion. Aflac Japan recognized an expense of ¥1.9 billion and ¥2.0 billion for the years ended December 31, 2019 and 2018, respectively, for LIPPC assessments.

Guaranty Fund Assessments

Under U.S. state guaranty association laws, certain insurance companies can be assessed (up to prescribed limits) for certain obligations to the policyholders and claimants of impaired or insolvent insurance companies that write the same line or similar lines of business. The amount of the guaranty fund assessment that an insurer is assessed is based on its proportionate share of premiums in that state. See Note 15 of the Notes to the Consolidated Financial Statements for further information on the assessment.

OFF-BALANCE SHEET ARRANGEMENTS

As of December 31, 2019, the Company had no material letters of credit, standby letters of credit, guarantees or standby repurchase obligations. See Note 15 of the Notes to the Consolidated Financial Statements for information on material unconditional purchase obligations that are not recorded on the Company's balance sheet.

Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations


LIQUIDITY AND CAPITAL RESOURCES
Liquidity refers to the ability to generate sufficient cash resources to meet the payment obligations of the Company. Capital refers to the long-term financial resources available to support the operations of the businesses, fund business growth and provide for an ability to withstand adverse circumstances. Financial leverage (leverage) refers to an investment strategy of using debt to increase the potential return on equity. The Company targets and actively manages liquidity, capital and leverage in the context of a number of considerations, including:

business investment and growth needs
strategic growth objectives
financial flexibility and obligations
capital support for hedging activity
a constantly evolving business and economic environment
a balanced approach to capital allocation and shareholder deployment.

The governance framework supporting liquidity, capital and leverage includes global senior management and board committees that review and approve all significant capital related decisions.

The Company's cash and cash equivalents include unrestricted cash on hand, money market instruments, and other debt instruments with a maturity of 90 days or less when purchased, all of which has minimal market, settlement or other risk exposure. The target minimum amount for the Parent Company’s cash and cash equivalents is approximately $2.0 billion to provide available capital and liquidity support at the holding company.Aflac Japan and Aflac U.S. provide the primary sources of liquidity to the Parent Company through the payment of dividends and management fees. The following table presents the amounts provided to the Parent Company for the years ended December 31.

The decline in dividends during 2018 was driven by a change in the dividend regulatory approval process subsequent to the conversion of Aflac Japan from a branch to a subsidiary on April 1, 2018. The Company resumed dividend payments from Aflac Japan in the fourth quarter of 2018. Management fees decreased during 2019 and 2018, compared to prior years, due to changes in the administration of intercompany expenses between legal entities subsequent to the conversion, as well.

Prior to the Aflac Japan branch conversion, Aflac Japan paid allocated expenses and profit remittances to Aflac U.S. The following table details Aflac Japan remittances for the years ended December 31.

In 2018, the Company announced a change in its internal dividend policy which allows the Company to increase the proportion of regulatory earnings transferred from Aflac U.S. and Aflac Japan to the Parent Company. The Company intends to maintain higher than historical levels of capital and liquidity at the Parent Company with the goals of addressing the Company’s hedge costs and related potential need for collateral and mitigating against long-term weakening of the Japanese yen. Further, the Company plans to continue to maintain a portfolio of unhedged U.S. dollar based investments at Aflac Japan and consider whether the amount of such investments should be increased or decreased relative to the Company’s view of economic equity surplus in Aflac Japan in light of potentially rising hedge costs and other factors. See the "Hedging Activity" subsection in this MD&A for more information.

Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations

In addition to cash and equivalents, the Company also maintains credit facilities, both intercompany and with external partners, and a number of other available tools to support liquidity needs on a global basis. In September 2018, the Parent Company filed a shelf registration statement with the SEC that allows the Company to issue an indefinite amount of debt securities, in one or more series, from time to time until September 2021. In August 2018, the Parent Company filed a shelf registration with Japanese regulatory authorities that allows the Parent Company to conduct public offerings of bonds in Japan, including yen-denominated Samurai notes, up to ¥200 billion or its equivalent through August 2020. The shelf registration statement is for possible public offerings in Japan, but the bonds issued under the shelf may be transferred by the bondholders to U.S. persons in compliance with U.S. law. The Company believes outside sources for additional debt and equity capital, if needed, will continue to be available. Additionally, as of December 31, 2019, the Parent Company and Aflac had four lines of credit with third parties and three intercompany lines of credit. For additional information, see Note 9 of the Notes to the Consolidated Financial Statements.

The primary uses of cash by the Parent Company are shareholder dividends, the repurchase of its common stock and interest on its outstanding indebtedness and operating expenses.

Liabilities for unrecognized tax benefits in the amount of $17 have been excluded from the tabular disclosure above because the timing of cash payment is not reasonably estimable.
(1)Liability amounts are those reported on the consolidated balance sheet as of December 31, 2019.
(2)The estimated payments due by period reflect future estimated cash payments to be made to policyholders and others for future policy benefits. These projected cash outflows are based on assumptions for future policy persistency, mortality, morbidity, and other assumptions comparable with the Company's experience, consider future premium receipts on current policies in force, and assume market growth and interest crediting consistent with assumptions used in amortizing deferred acquisition costs. These cash outflows are undiscounted with respect to interest and, as a result, the sum of the cash outflows shown for all years in the table of $244,884 exceeds the corresponding liability amount of $90,335. The Company has made significant assumptions to determine the future estimated cash outflows related to the underlying policies and contracts. Due to the significance of the assumptions used, actual cash outflow amounts and timing will differ, possibly materially, from these estimates.

including securities lending transactions. See Notes 1, 3, and 4 of the Notes to the Consolidated Financial Statements for more information on the Company's securities lending and derivative activities. With the exception of disclosed activities in those referenced footnotes and the Risk Factors entitled, "The Company is exposed to foreign currency fluctuations in the yen/dollar exchange rate" and "Lack of availability of acceptable yen-denominated investments could adversely affect the Company's results of operations, financial position or liquidity," the Company is not aware of a trend, demand, commitment, event or uncertainty that would likely result in its liquidity increasing or decreasing by a material amount.
Consolidated Cash Flows

The Company translates cash flows for Aflac Japan's yen-denominated items into U.S. dollars using weighted-average exchange rates. In years when the yen weakens, translating yen into dollars causes fewer dollars to be reported. When the yen strengthens, translating yen into dollars causes more dollars to be reported.

Operating Activities
The principal cash inflows for the Company's insurance activities come from insurance premiums and investment income. The principal cash outflows are the result of policy claims, operating expenses, income tax, as well as interest expense. As a result of policyholder aging, claims payments are expected to gradually increase over the life of a policy. Therefore, future policy benefit reserves are accumulated in the early years of a policy and are designed to help fund future claims payments.
The Company expects its future cash flows from premiums and its investment portfolio to be sufficient to meet its cash needs for benefits and expenses. Consolidated cash flow from operations decreased 9.3% in 2019, compared with 2018.
Investing Activities
The Company's investment objectives provide for liquidity primarily through the purchase of publicly traded investment-grade debt securities. Prudent portfolio management dictates that the Company attempts to match the duration of its assets with the duration of its liabilities. Currently, when the Company's fixed maturity securities mature, the proceeds may be reinvested at a yield below that required for the accretion of policy benefit liabilities on policies issued in earlier years. However, the long-term nature of the Company's business and its strong cash flows provide the Company with the ability to minimize the effect of mismatched durations and/or yields identified by various asset adequacy analyses. From time to time or when market opportunities arise, the Company disposes of selected fixed maturity securities that are available for sale to improve the duration matching of assets and liabilities, improve future investment yields, and/or re-balance its portfolio. As a result, dispositions before maturity can vary significantly from year to year.

As part of its overall corporate strategy, the Company has announced an increase in its commitment to the Aflac Ventures Fund from $250 million to $400 million, as opportunities emerge. These investments are included in equity securities or the other investments line in the consolidated balance sheets. The Aflac Ventures Fund is a subsidiary of Aflac Corporate Ventures which is reported in the Corporate and other segment. The central mission of Aflac Corporate Ventures is to support the organic growth and business development needs of Aflac Japan and Aflac U.S. with emphasis on digital applications designed to improve the customer experience, gain efficiencies, and develop new markets in an effort to enhance and defend long-term shareholder value.

As part of an arrangement with Federal Home Loan Bank of Atlanta (FHLB), Aflac U.S. obtains low-cost funding from FHLB supported by acceptable forms of collateral pledged by Aflac U.S. Aflac U.S. borrowed and repaid $217 million under this program during 2019. As of December 31, 2019, Aflac U.S. had outstanding borrowings of $403 million reported in its balance sheet.

In September 2019, the Parent Company renewed a ¥30.0 billion senior term loan facility. The first tranche of the facility, which totaled ¥5.0 billion, bears interest at a rate per annum equal to the Tokyo interbank market rate (TIBOR), or alternate TIBOR, if applicable, plus the applicable TIBOR margin and will mature in September 2026. The applicable margin ranges between .30% and .70%, depending on the Parent Company's debt ratings as of the date of determination. The second tranche, which totaled ¥25.0 billion, bears interest at a rate per annum equal to the TIBOR, or alternate TIBOR, if applicable, plus the applicable TIBOR margin and will mature in September 2029. The applicable margin ranges between .45% and 1.00%, depending on the Parent Company's debt ratings as of the date of determination.

In April 2019, ALIJ issued ¥30.0 billion (par value) of perpetual subordinated bonds. These bonds bear interest at a fixed rate of .963% per annum and then at six-month Euro Yen LIBOR plus an applicable spread on and after the day immediately following April 18, 2024. The bonds will be callable on each interest payment date on and after April 18, 2024. In November 2019, ALIJ amended the bonds to change their duration from perpetual to a stated maturity date of April 16, 2049 and to remove provisions that permitted ALIJ to defer payments of interest under certain circumstances.

In October 2018, the Parent Company issued $550 million of senior notes through a U.S. public debt offering. The notes bear interest at a fixed rate of 4.750% per annum, payable semi-annually, and will mature in January 2049. These notes are redeemable at the Parent Company's option in whole at any time or in part from time to time at a redemption price equal to the greater of: (i) the aggregate principal amount of the notes to be redeemed or (ii) the amount equal to the sum of the present values of the remaining scheduled payments for principal of and interest on the notes to be redeemed, not including any portion of the payments of interest accrued as of such redemption date, discounted to such redemption date on a semiannual basis at the yield to maturity for a U.S.Treasury security with a maturity comparable to the remaining term of the notes, plus 25 basis points, plus in each case, accrued and unpaid interest on the principal amount of the notes to be redeemed to, but excluding, such redemption date.

In October 2018, the Parent Company issued three series of senior notes totaling ¥53.4 billion through a public debt offering under its U.S. shelf registration statement. The first series, which totaled ¥29.3 billion, bears interest at a fixed rate of 1.159% per annum, payable semi-annually, and will mature in October 2030. The second series, which totaled ¥15.2 billion, bears interest at a fixed rate of 1.488% per annum, payable semi-annually, and will mature in October 2033. The third series, which totaled ¥8.9 billion, bears interest at a fixed rate of 1.750% per annum, payable semi-annually, and will mature in October 2038. These notes may only be redeemed before maturity, in whole but not in part, upon the occurrence of certain changes affecting U.S. taxation, as specified in the indenture governing the terms of the issuance.

In November 2018, the Parent Company used the net proceeds from the October 2018 issuance of its senior notes to redeem $550 million of the Parent Company's 2.40% senior notes due in 2020.

See Note 9 of the Notes to the Consolidated Financial Statements for further information on the debt issuances discussed above.

The Company was in compliance with all of the covenants of its notes payable and lines of credit at December 31, 2019.

Cash returned to shareholders through treasury stock purchases and dividends was $2.4 billion in 2019, compared with $2.1 billion in 2018.

Under share repurchase authorizations from the Company's board of directors, the Company purchased 32.0 million shares of its common stock in 2019, compared with 28.9 million shares in 2018. As of December 31, 2019, a remaining balance of 37.1 million shares of the Company's common stock was available for purchase under share repurchase authorizations by its board of directors. The Company currently plans to repurchase $1.3 billion to $1.7 billion of its common stock in 2020, assuming stable capital conditions and absent compelling alternatives. See Note 11 of the Notes to the Consolidated Financial Statements for additional information.

Cash dividends paid to shareholders in 2019 of $1.08 per share increased 3.8% over 2018. The following table presents the dividend activity for the years ended December 31.

Regulatory Restrictions

Aflac, CAIC and TOIC are domiciled in Nebraska and are subject to its regulations. Subsequent to the Japan branch conversion to a subsidiary, Aflac Japan is domiciled in Japan and subject to local regulations. The Nebraska Department of Insurance imposes certain limitations and restrictions on payments of dividends, management fees, loans and advances to the Parent Company. Under Nebraska insurance law, prior approval of the Nebraska Department of Insurance is required for dividend distributions that exceed the greater of the net income from operations, which excludes net realized investment gains, for the previous year determined under statutory accounting principles, or 10% of statutory capital and surplus as of the previous year-end. In addition, the Nebraska insurance department must approve service arrangements and other transactions within the affiliated group of companies. These regulatory limitations are not expected to affect the level of management fees or dividends paid to the Parent Company. (See below for discussion of restrictions imposed by Japanese insurance regulators.) A life insurance company’s statutory capital and surplus is determined according to rules prescribed by the NAIC, as modified by the insurance department in the insurance company’s state of domicile. Statutory accounting rules are different from U.S. GAAP and are intended to emphasize policyholder protection and company solvency. Similar laws apply in New York, the domiciliary jurisdiction of Aflac New York.

Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations

The continued long-term growth of the Company's business may require increases in the statutory capital and surplus of its insurance operations. Aflac’s insurance operations may secure additional statutory capital through various sources, such as internally generated statutory earnings, capital contributions by the Parent Company from funds generated through debt or equity offerings, or reinsurance transactions. The NAIC’s RBC formula is used by insurance regulators to help identify inadequately capitalized insurance companies. The RBC formula quantifies insurance risk, business risk, asset risk and interest rate risk by weighing the types and mixtures of risks inherent in the insurer’s operations.

Aflac's company action level RBC ratio was 539% as of December 31, 2019, compared with 560% at December 31, 2018. Aflac’s RBC ratio remains high and reflects a strong capital and surplus position. As of December 31, 2019, Aflac's total adjusted capital of $2.2 billion exceeded the company action level required capital and surplus of $.4 billion by $1.8 billion. With the announcement of the Japan branch conversion to a subsidiary, we had announced our intention to remove excess capital out of Aflac, targeting a 500% RBC by the end of 2019. As of December 31, 2019, the Company has completed the RBC drawdown plan and has moved $1.75 billion of capital from Aflac to the Parent Company, supporting the Company's capital deployment and risk management activities.

The maximum amount of dividends that can be paid to the Parent Company by Aflac, CAIC and TOIC without prior approval of Nebraska's director of insurance is the greater of the net income from operations, which excludes net realized investment gains, for the previous year determined under statutory accounting principles, or 10% of statutory capital and surplus as of the previous year-end. Dividends declared by Aflac during 2020 in excess of $864 million would be considered extraordinary and require such approval. Following the Japan branch conversion to a subsidiary, the Company used extraordinary dividends as needed to actively manage to appropriate RBC levels that are lower yet sufficient to maintain ratings and support prudent capital management. Similar laws apply in New York, the domiciliary jurisdiction of Aflac New York. See Note 13 of the Notes to the Consolidated Financial Statements for information regarding the impact of permitted practices by the Nebraska Department of Insurance on the Company's statutory capital and surplus.

The NAIC considers its Solvency Modernization Initiative (SMI) process relating to updating the U.S. insurance solvency regulation framework to be ongoing. The SMI has focused on key issues such as capital requirements, governance and risk management, group supervision, reinsurance, statutory accounting and financial reporting matters. Many of these key issues have been finalized and/or are near completion; however, the NAIC still has some ongoing initiatives related to SMI, such as monitoring the international efforts on group capital requirements as well as RBC.In addition, the NAIC is also considering changes to investment risk factors. Any negative developments by the NAIC in these areas could result in increased capital requirements for the Company.

Aflac is subject to the NAIC’s Own Risk and Solvency Assessment (ORSA). Through the ORSA requirements, Aflac is expected to regularly, no less than annually, conduct an ORSA to assess the adequacy of its risk management framework, and its current and estimated projected future solvency position; internally document the process and results of the assessment; and provide a confidential high-level ORSA Summary Report annually to the lead state commissioner if the insurer is a member of an insurance group. In November 2019, Aflac filed its ORSA report with the Nebraska Department of Insurance.

In addition to limitations and restrictions imposed by U.S. insurance regulators, after the Japan branch conversion on April 1, 2018, the new Japan subsidiary is required to meet certain financial criteria as governed by Japanese corporate law in order to provide dividends to the Parent Company. Under these criteria, dividend capacity at the Japan subsidiary is basically defined as total equity excluding common stock, accumulated other comprehensive income amounts, capital reserves (representing statutorily required amounts in Japan) but reduced for net after-tax unrealized losses on available-for-sale securities. These dividend capacity requirements are generally aligned with the SMR. Japan's FSA maintains its own solvency standard which is quantified through the SMR. Aflac Japan's SMR is sensitive to interest rate, credit spread, and foreign exchange rate changes, therefore the Company continues to evaluate alternatives for reducing this sensitivity. In the event of a rapid change in market risk conditions causing SMR to decline, the Company has one senior unsecured revolving credit facility in the amount of ¥100 billion and a committed reinsurance facility in the amount of approximately ¥110 billion as a capital contingency plan. Additionally, the Company could take action to enter into derivatives on unhedged U.S. dollar-denominated investments with foreign currency options or forwards. See Notes 8 and 9 of the Notes to the Consolidated Financial Statements for additional information.

The Company has already undertaken various measures to mitigate the sensitivity of Aflac Japan's SMR. For example, the Company employs policy reserve matching (PRM) investment strategies, which is a Japan-specific accounting treatment that reduces SMR interest rate sensitivity since PRM-designated investments are carried at amortized cost consistent with corresponding liabilities. In order for a PRM-designated asset to be held at amortized cost, there are certain criteria that must be maintained. The primary criteria relates to maintaining the duration of designated assets and liabilities within a specified tolerance range. If the duration difference is not maintained within the specified range without rebalancing, then a certain

63


Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations

portion of the assets must be re-classified as available for sale and held at fair value with any associated unrealized gain or loss recorded in surplus. To rebalance, assets may need to be sold in order to maintain the duration with the specified range, resulting in realizing a gain or loss from the sale. For U.S. GAAP, PRM investments are categorized as available for sale. The Company also uses foreign currency derivatives to hedge a portion of its U.S. dollar-denominated investments.(See Notes 3, 4 and 8 of the Notes to the Consolidated Financial Statements for additional information on the Company's investment strategies, hedging activities, and reinsurance, respectively.)

Aflac's SMR ratio remains high and reflects a strong capital and surplus position. As of December 31, 2019, Aflac Japan's SMR was 1,043%, compared with 965% at December 31, 2018. As part of the conversion of Aflac Japan from a branch to a subsidiary on April 1, 2018, the Company experienced an accounting-driven decline in the SMR of approximately 130 points, compared with the SMR as of December 31, 2017. The Company expects to be able to pay dividends out of certain accounts, thus restoring this accounting impact over an estimated three-year period.

The FSA has been conducting field testing with the insurance industry concerning the introduction of an economic value-based solvency regime. The field testing will assist the FSA in determining if an economic value-based solvency regime in Japan will be appropriate for the insurance industry.

Privacy and Cybersecurity Governance

The Company’s Board of Directors has adopted an information security policy directing management to establish and operate a global information security program with the goals of monitoring existing and emerging threats and ensuring that the Company’s information assets and data, and the data of its customers, are appropriately protected from loss or theft. The Board has delegated oversight of the Company’s information security program to the Audit and Risk Committee. The Company’s senior officers, including its Global Security and Chief Information Security Officer, are responsible for the operation of the global information security program and regularly communicate with the Audit and Risk Committee on the program, including with respect to the state of the program, compliance with applicable regulations, current and evolving threats, and recommendations for changes in the information security program. The global information security program also includes a cybersecurity incident response plan that is designed to provide a management framework across Company functions for a coordinated assessment and response to potential security incidents. This framework establishes a protocol to report certain incidents to the Global Security and Chief Information Security Officer and other senior officers, with the goal of timely assessing such incidents, determining applicable disclosure requirements and communicating with the Audit and Risk Committee. The incident response plan directs the executive officers to report certain incidents immediately and directly to the Lead Non-Management Director.

Additional Information

Investors should note that the Company announces material financial information in its SEC filings, press releases and public conference calls. In accordance with SEC guidance, the Company may also use the Investor Relations section of the Company's website (http://investors.aflac.com) to communicate with investors about the Company. It is possible that the financial and other information the Company posts there could be deemed to be material information. The information on the Company's website is not part of this document. Further, the Company's references to website URLs are intended to be inactive textual references only.

CRITICAL ACCOUNTING ESTIMATES

The Company prepares its financial statements in accordance with U.S. GAAP. These principles are established primarily by the FASB. In this MD&A, references to U.S. GAAP issued by the FASB are derived from the FASB Accounting Standards Codification™ (ASC). The preparation of financial statements in conformity with U.S. GAAP requires the Company to make estimates based on currently available information when recording transactions resulting from business operations. The estimates that the Company deems to be most critical to an understanding of Aflac’s results of operations and financial condition are those related to the valuation of investments and derivatives, DAC, liabilities for future policy benefits and unpaid policy claims, and income taxes. The preparation and evaluation of these critical accounting estimates involve the use of various assumptions developed from management’s analyses and judgments. The application of these critical accounting estimates determines the values at which 94% of the Company's assets and 81% of its liabilities are reported as

64


Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations

of December 31, 2019, and thus has a direct effect on net earnings and shareholders' equity. Subsequent experience or use of other assumptions could produce significantly different results.

Valuation of Investments, Including Derivatives, and Recognition of Other-than-Temporary Impairments

Aflac's investments, primarily consisting of debt and equity securities, include both publicly issued and privately issued securities. For publicly issued securities, the Company determines the fair values from quoted market prices readily available from public exchange markets and price quotes and valuations from third party pricing vendors. For the majority of privately issued securities within the Company's investment portfolio, a third party pricing vendor has developed valuation models that the Company utilizes to determine fair values. For the remaining privately issued securities, the Company uses non-binding price quotes from outside brokers.

The Company estimates the fair values of its securities on a monthly basis. The Company monitors the estimated fair values obtained from its pricing vendors and brokers for consistency from month to month, while considering current market conditions. The Company also periodically discusses with its pricing brokers and vendors the pricing techniques they use to monitor the consistency of their approach and periodically assess the appropriateness of the valuation level assigned to the values obtained from them. If a fair value appears unreasonable, the Company will re-examine the inputs and assess the reasonableness of the pricing data with the vendor. Additionally, the Company may compare the inputs to relevant market indices and other performance measurements. Based on management's analysis, the valuation is confirmed or may be revised if there is evidence of a more appropriate estimate of fair value based on available market data. The Company has performed verification of the inputs and calculations in any valuation models to confirm that the valuations represent reasonable estimates of fair value. Inputs used to value derivatives include, but are not limited to, interest rates, credit spreads, foreign currency forward and spot rates, and interest volatility.

The Company routinely reviews its investments that have experienced declines in fair value to determine if the decline is other than temporary. The identification of distressed investments, the determination of fair value if not publicly traded and the assessment of whether a decline is other than temporary involve significant management judgment. The Company must apply considerable judgment in determining the likelihood of the security recovering in value while the Company owns it. Factors that may influence this include the Company's assessment of the issuer’s ability to continue making timely payments of interest and principal, the overall level of interest rates and credit spreads, and other factors. This process requires consideration of risks, which can be controlled to a certain extent, such as credit risk, and risks which cannot be controlled, such as interest rate risk. Management updates its evaluations regularly and reflects impairment losses in the Company's net earnings or other comprehensive income, depending on the nature of the loss, as such evaluations are revised.

See Notes 1, 3, 4 and 5 of the Notes to the Consolidated Financial Statements for additional information.

Deferred Policy Acquisition Costs and Policy Liabilities

Insurance premiums for most of the Company's health and life policies, including cancer, accident, hospital, critical illness, dental, vision, term life, whole life, long-term care and disability, are recognized as revenue over the premium-paying periods of the contracts when due from policyholders. When revenues are reported, the related amounts of benefits and expenses are charged against such revenues, so that profits are recognized in proportion to premium revenues during the period the policies are expected to remain in force. This association is accomplished by means of annual additions to the liability for future policy benefits and the deferral and subsequent amortization of policy acquisition costs.

Premiums from the Company's products with limited-pay features, including term life, whole life, WAYS, and child endowment, are collected over a significantly shorter period than the period over which benefits are provided. Premiums for these products are recognized as revenue over the premium-paying periods of the contracts when due from policyholders. Any gross premium in excess of the net premium is deferred and recorded in earnings, such that profits are recognized in a constant relationship with insurance in force. Benefits are recorded as an expense when they are incurred. A liability for future policy benefits is recorded when premiums are recognized using the net premium method.

(1)Liability amounts are those reported on the consolidated balance sheet as of December 31, 2019.
(2)The estimated payments due by period reflect future estimated cash payments to be made to policyholders and others for future policy benefits. These projected cash outflows are based on assumptions for future policy persistency, mortality, morbidity, and other assumptions comparable with the Company's experience, consider future premium receipts on current policies in force, and assume market growth and interest crediting consistent with assumptions used in amortizing deferred acquisition costs. These cash outflows are undiscounted with respect to interest and, as a result, the sum of the cash outflows shown for all years in the table of $244,884 exceeds the corresponding liability amount of $90,335. The Company has made significant assumptions to determine the future estimated cash outflows related to the underlying policies and contracts. Due to the significance of the assumptions used, actual cash outflow amounts and timing will differ, possibly materially, from these estimates.

With the exception of disclosed activities in those referenced footnotes and the Risk Factors entitled, "The Company is exposed to foreign currency fluctuations in the yen/dollar exchange rate" and "Lack of availability of acceptable yen-denominated investments could adversely affect the Company's results of operations, financial position or liquidity," the Company is not aware of a trend, demand, commitment, event or uncertainty that would likely result in its liquidity increasing or decreasing by a material amount.
Consolidated Cash Flows

The Company translates cash flows for Aflac Japan's yen-denominated items into U.S. dollars using weighted-average exchange rates. In years when the yen weakens, translating yen into dollars causes fewer dollars to be reported. When the yen strengthens, translating yen into dollars causes more dollars to be reported.

Notes Payable
Notes payable totaled $5.3 billion at December 31, 2017, compared with $5.4 billion at December 31, 2016.

In January 2017, the Parent Company issued 60.0 billion yen of senior notes through a U.S. public debt offering. The notes bear interest at a fixed rate of .932% per annum, payable semi-annually, and have a 10-year maturity. These notes may only be redeemed before maturity, in whole but not in part, upon the occurrence of certain changes affecting U.S. taxation, as specified in the indenture governing the terms of the issuance.

In February 2017, the Parent Company extinguished $650 million of 2.65% senior notes upon their maturity.

In October 2017, the Parent Company issued 60.0 billion yen of subordinated debentures through a U.S. public debt offering. The debentures bear interest at an initial rate of 2.108% per annum through October 22, 2027, or earlier redemption. Thereafter, the rate of the interest of the debentures will be reset every five years at a rate of interest equal to the then-current JPY 5-year Swap Offered Rate plus 205 basis points. The debentures are payable semi-annually in arrears and have a 30-year maturity. The debentures are redeemable (i) at any time, in whole but not in part, upon the occurrence of certain tax events or certain rating agency events, as specified in the indenture governing the terms of the debentures or (ii) in 10 years, in whole or in part, at a redemption price equal to their principal amount plus accrued and unpaid interest. In November 2017, the Parent Company used a portion of net proceeds from the debenture offering to redeem $500 million of the Parent Company's 5.50% subordinated debentures due 2052. The pretax non-operating expense due to the early redemption of these notes was $13 million.

Benefit Plans
Aflac Japan and Aflac U.S. have various benefit plans. For additional information on the Company's Japanese and U.S. plans, see Note 14 of the Notes to the Consolidated Financial Statements.

Policyholder Protection
Policyholder Protection Corporation

The Japanese insurance industry has a policyholder protection system that provides funds for the policyholders of insolvent insurers. Legislation enacted regarding the framework of the Life Insurance Policyholder Protection Corporation (LIPPC) included government fiscal measures supporting the LIPPC. On March 30, 2012, the Diet approved legislation to enhance the stability of the LIPPC by extending the government's fiscal support of the LIPPC through March 2017. On November 25, 2016, Japan's Diet passed legislation that again extends the government's fiscal support of the LIPPC through March 2022. Effective April 2014, the annual LIPPC contribution amount for the total life industry was lowered from 40 billion yen to 33 billion yen.

Guaranty Fund Assessments

Under U.S. state guaranty association laws, certain insurance companies can be assessed (up to prescribed limits) for certain obligations to the policyholders and claimants of impaired or insolvent insurance companies that write the same line or similar lines of business. The amount of the guaranty fund assessment that an insurer is assessed is based on its proportionate share of premiums in that state.

As of December 31, 2017, the Company has estimated and recognized the impact of its share of guaranty fund assessments resulting from the liquidation of a long-term care insurer. See Note 15 of the Notes to the Consolidated Financial Statements for further information on the assessment.

Off-Balance Sheet Arrangements

As of December 31, 2017, the Company had no material letters of credit, standby letters of credit, guarantees or standby repurchase obligations. See Note 15 of the Notes to the Consolidated Financial Statements for information on material unconditional purchase obligations that are not recorded on the Company's balance sheet.
CAPITAL RESOURCES AND LIQUIDITY
Aflac provides the primary sources of liquidity to the Parent Company through dividends and management fees. The following table presents the amounts provided for the years ended December 31.

The primary uses of cash by the Parent Company are shareholder dividends, the repurchase of its common stock and interest on its outstanding indebtedness and operating expenses. The Parent Company's sources and uses of cash are reasonably predictable and are not expected to change materially in the future. For additional information, see the FinancingOperating Activities subsection of this MD&A.

The Parent Company also accesses debt security markets to provide additional sources of capital. In August 2016, the Company filed a shelf registration statement with Japanese regulatory authorities that allows the Company to conduct public offerings of bonds in Japan, including yen-denominated Samurai notes, up to 200 billion yen or its equivalent through August 2018. The shelf registration statement is for possible public offerings in Japan, but the bonds issued under the shelf may be transferred by the bondholders to U.S. persons in compliance with U.S. law. The Company filed a shelf

65



registration statement with the SEC in May 2015 that allows the Company to issue an indefinite amount of senior and subordinated debt, in one or more series, from time to time until May 2018. The Company believes outside sources for additional debt and equity capital, if needed, will continue to be available. For additional information, see Note 9 of the Notes to the Consolidated Financial Statements.

The principal sources of cash inflows for the Company's insurance operations areactivities come from insurance premiums and investment income. The primary usesprincipal cash outflows are the result of cash by the Company's insurance operations are investments, policy claims, commissions, operating expenses, income taxes and payments to the Parent Company for management fees and dividends. Both the sources and uses of cash are reasonably predictable.

When making an investment decision, the Company's first consideration is based on product needs. The Company's investment objectives provide for liquidity through the purchase of investment-grade debt securities. These objectives also take into account duration matching, and because of the long-term nature of the Company's business, the Company has adequate time to react to changing cash flow needs.

tax, as well as interest expense. As a result of policyholder aging, claims payments are expected to gradually increase over the life of a policy. Therefore, future policy benefit reserves are accumulated in the early years of a policy and are designed to help fund future claims payments.
The Company expects its future cash flows from premiums and its investment portfolio to be sufficient to meet its cash needs for benefits and expenses. Consolidated cash flow from operations decreased 9.3% in 2019, compared with 2018.

Investing Activities
The Company's investment objectives provide for liquidity primarily through the purchase of publicly traded investment-grade debt securities. Prudent portfolio management dictates that the Company attempts to match the duration of its assets with the duration of its liabilities. Currently, when the Company's fixed maturity securities mature, the proceeds may be reinvested at a yield below that required for the accretion of policy benefit liabilities on policies issued in earlier years. However, the long-term nature of the Company's business and its strong cash flows provide the Company with the ability to minimize the effect of mismatched durations and/or yields identified by various asset adequacy analyses. From time to time or when market opportunities arise, the Company disposes of selected fixed maturity securities that are available for sale to improve the duration matching of assets and liabilities, improve future investment yields, and/or re-balance its portfolio. As a result, dispositions before maturity can vary significantly from year to year.

As part of its overall corporate strategy, the Company has announced an increase in its commitment to the Aflac Ventures Fund from $250 million to $400 million, as opportunities emerge. These investments are included in equity securities or the other investments line in the consolidated balance sheets. The Aflac Ventures Fund is a subsidiary of Aflac Corporate Ventures which is reported in the Corporate and other segment. The central mission of Aflac Corporate Ventures is to support the organic growth and business development needs of Aflac Japan and Aflac U.S. with emphasis on digital applications designed to improve the customer experience, gain efficiencies, and develop new markets in an effort to enhance and defend long-term shareholder value.

As part of an arrangement with Federal Home Loan Bank of Atlanta (FHLB), Aflac U.S. obtains low-cost funding from FHLB supported by acceptable forms of collateral pledged by Aflac U.S. Aflac U.S. borrowed and repaid $217 million under this program during 2019. As of December 31, 2017,2019, Aflac U.S. had outstanding borrowings of $403 million reported in its balance sheet.

Consolidated cash used by financing activities was $1.7 billion in 2019 and $1.6 billion in 2018.

In December 2019, the Parent Company issued four series of senior notes totaling ¥38.0 billion through a public debt offering under its U.S. shelf registration statement. The first series, which totaled ¥12.6 billion, bears interest at a fixed rate of .500% per annum, payable semi-annually, and Aflac had four lineswill mature in December 2029. The second series, which totaled ¥9.3 billion, bears interest at a fixed rate of credit with.843% per annum, payable semi-annually, and will mature in December 2031. The third partiesseries, which totaled ¥9.8 billion, bears interest at a fixed rate of .934% per annum, payable semi-annually, and will mature in December 2034. The fourth series, which totaled ¥6.3 billion, bears interest at a fixed rate of 1.122% per annum, payable semi-annually, and will mature in December 2039. These notes may only be redeemed before maturity, in whole but not in part, upon the occurrence of certain changes affecting U.S. taxation, as well as two intercompany linesspecified in the indenture governing the terms of credit. For additional informationthe issuance.

In September 2019, the Parent Company renewed a ¥30.0 billion senior term loan facility. The first tranche of the facility, which totaled ¥5.0 billion, bears interest at a rate per annum equal to the Tokyo interbank market rate (TIBOR), or alternate TIBOR, if applicable, plus the applicable TIBOR margin and will mature in September 2026. The applicable margin ranges between .30% and .70%, depending on the Parent Company's linesdebt ratings as of credit, seethe date of determination. The second tranche, which totaled ¥25.0 billion, bears interest at a rate per annum equal to the TIBOR, or alternate TIBOR, if applicable, plus the applicable TIBOR margin and will mature in September 2029. The applicable margin ranges between .45% and 1.00%, depending on the Parent Company's debt ratings as of the date of determination.

In April 2019, ALIJ issued ¥30.0 billion (par value) of perpetual subordinated bonds. These bonds bear interest at a fixed rate of .963% per annum and then at six-month Euro Yen LIBOR plus an applicable spread on and after the day immediately following April 18, 2024. The bonds will be callable on each interest payment date on and after April 18, 2024. In November 2019, ALIJ amended the bonds to change their duration from perpetual to a stated maturity date of April 16, 2049 and to remove provisions that permitted ALIJ to defer payments of interest under certain circumstances.

In October 2018, the Parent Company issued $550 million of senior notes through a U.S. public debt offering. The notes bear interest at a fixed rate of 4.750% per annum, payable semi-annually, and will mature in January 2049. These notes are redeemable at the Parent Company's option in whole at any time or in part from time to time at a redemption price equal to the greater of: (i) the aggregate principal amount of the notes to be redeemed or (ii) the amount equal to the sum of the present values of the remaining scheduled payments for principal of and interest on the notes to be redeemed, not including any portion of the payments of interest accrued as of such redemption date, discounted to such redemption date on a semiannual basis at the yield to maturity for a U.S.Treasury security with a maturity comparable to the remaining term of the notes, plus 25 basis points, plus in each case, accrued and unpaid interest on the principal amount of the notes to be redeemed to, but excluding, such redemption date.

In October 2018, the Parent Company issued three series of senior notes totaling ¥53.4 billion through a public debt offering under its U.S. shelf registration statement. The first series, which totaled ¥29.3 billion, bears interest at a fixed rate of 1.159% per annum, payable semi-annually, and will mature in October 2030. The second series, which totaled ¥15.2 billion, bears interest at a fixed rate of 1.488% per annum, payable semi-annually, and will mature in October 2033. The third series, which totaled ¥8.9 billion, bears interest at a fixed rate of 1.750% per annum, payable semi-annually, and will mature in October 2038. These notes may only be redeemed before maturity, in whole but not in part, upon the occurrence of certain changes affecting U.S. taxation, as specified in the indenture governing the terms of the issuance.

In November 2018, the Parent Company used the net proceeds from the October 2018 issuance of its senior notes to redeem $550 million of the Parent Company's 2.40% senior notes due in 2020.

See Note 9 of the Notes to the Consolidated Financial Statements.Statements for further information on the debt issuances discussed above.

Regulatory Restrictions

Aflac, CAIC and TOIC are domiciled in Nebraska and are subject to its regulations. Subsequent to the Japan branch conversion to a subsidiary, Aflac Japan is domiciled in Japan and subject to local regulations. The Nebraska Department of Insurance imposes certain limitations and restrictions on payments of dividends, management fees, loans and advances to the Parent Company. Under Nebraska insurance law, prior approval of the Nebraska Department of Insurance is required for dividend distributions that exceed the greater of the net income from operations, which excludes net realized investment gains, for the previous year determined under statutory accounting principles, or 10% of statutory capital and surplus as of the previous year-end. In addition, the Nebraska insurance department must approve service arrangements and other transactions within the affiliated group of companies. These regulatory limitations are not expected to affect the level of management fees or dividends paid to the Parent Company. (See below for discussion of restrictions imposed by periodJapanese insurance regulators.) A life insurance company’s statutory capital and surplus is determined according to rules prescribed by the NAIC, as modified by the insurance department in the insurance company’s state of domicile. Statutory accounting rules are different from U.S. GAAP and are intended to emphasize policyholder protection and company solvency. Similar laws apply in New York, the domiciliary jurisdiction of Aflac New York.

Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations

The continued long-term growth of the Company's major contractual obligationsbusiness may require increases in the statutory capital and surplus of its insurance operations. Aflac’s insurance operations may secure additional statutory capital through various sources, such as internally generated statutory earnings, capital contributions by the Parent Company from funds generated through debt or equity offerings, or reinsurance transactions. The NAIC’s RBC formula is used by insurance regulators to help identify inadequately capitalized insurance companies. The RBC formula quantifies insurance risk, business risk, asset risk and interest rate risk by weighing the types and mixtures of risks inherent in the insurer’s operations.

Aflac's company action level RBC ratio was 539% as of December 31, 2019, compared with 560% at December 31, 2018. Aflac’s RBC ratio remains high and reflects a strong capital and surplus position. As of December 31, 2019, Aflac's total adjusted capital of $2.2 billion exceeded the company action level required capital and surplus of $.4 billion by $1.8 billion. With the announcement of the Japan branch conversion to a subsidiary, we had announced our intention to remove excess capital out of Aflac, targeting a 500% RBC by the end of 2019. As of December 31, 2019, the Company has completed the RBC drawdown plan and has moved $1.75 billion of capital from Aflac to the Parent Company, supporting the Company's capital deployment and risk management activities.

The maximum amount of dividends that can be paid to the Parent Company by Aflac, CAIC and TOIC without prior approval of Nebraska's director of insurance is the greater of the net income from operations, which excludes net realized investment gains, for the previous year determined under statutory accounting principles, or 10% of statutory capital and surplus as of the previous year-end. Dividends declared by Aflac during 2020 in excess of $864 million would be considered extraordinary and require such approval. Following the Japan branch conversion to a subsidiary, the Company used extraordinary dividends as needed to actively manage to appropriate RBC levels that are lower yet sufficient to maintain ratings and support prudent capital management. Similar laws apply in New York, the domiciliary jurisdiction of Aflac New York. See Note 13 of the Notes to the Consolidated Financial Statements for information regarding the impact of permitted practices by the Nebraska Department of Insurance on the Company's statutory capital and surplus.

The NAIC considers its Solvency Modernization Initiative (SMI) process relating to updating the U.S. insurance solvency regulation framework to be ongoing. The SMI has focused on key issues such as capital requirements, governance and risk management, group supervision, reinsurance, statutory accounting and financial reporting matters. Many of these key issues have been finalized and/or are near completion; however, the NAIC still has some ongoing initiatives related to SMI, such as monitoring the international efforts on group capital requirements as well as RBC.In addition, the NAIC is also considering changes to investment risk factors. Any negative developments by the NAIC in these areas could result in increased capital requirements for the Company.

Aflac is subject to the NAIC’s Own Risk and Solvency Assessment (ORSA). Through the ORSA requirements, Aflac is expected to regularly, no less than annually, conduct an ORSA to assess the adequacy of its risk management framework, and its current and estimated projected future solvency position; internally document the process and results of the assessment; and provide a confidential high-level ORSA Summary Report annually to the lead state commissioner if the insurer is a member of an insurance group. In November 2019, Aflac filed its ORSA report with the Nebraska Department of Insurance.

In addition to limitations and restrictions imposed by U.S. insurance regulators, after the Japan branch conversion on April 1, 2018, the new Japan subsidiary is required to meet certain financial criteria as governed by Japanese corporate law in order to provide dividends to the Parent Company. Under these criteria, dividend capacity at the Japan subsidiary is basically defined as total equity excluding common stock, accumulated other comprehensive income amounts, capital reserves (representing statutorily required amounts in Japan) but reduced for net after-tax unrealized losses on available-for-sale securities. These dividend capacity requirements are generally aligned with the SMR. Japan's FSA maintains its own solvency standard which is quantified through the SMR. Aflac Japan's SMR is sensitive to interest rate, credit spread, and foreign exchange rate changes, therefore the Company continues to evaluate alternatives for reducing this sensitivity. In the event of a rapid change in market risk conditions causing SMR to decline, the Company has one senior unsecured revolving credit facility in the amount of ¥100 billion and a committed reinsurance facility in the amount of approximately ¥110 billion as a capital contingency plan. Additionally, the Company could take action to enter into derivatives on unhedged U.S. dollar-denominated investments with foreign currency options or forwards. See Notes 8 and 9 of the Notes to the Consolidated Financial Statements for additional information.

The Company has already undertaken various measures to mitigate the sensitivity of Aflac Japan's SMR. For example, the Company employs policy reserve matching (PRM) investment strategies, which is a Japan-specific accounting treatment that reduces SMR interest rate sensitivity since PRM-designated investments are carried at amortized cost consistent with corresponding liabilities. In order for a PRM-designated asset to be held at amortized cost, there are certain criteria that must be maintained. The primary criteria relates to maintaining the duration of designated assets and liabilities within a specified tolerance range. If the duration difference is not maintained within the specified range without rebalancing, then a certain

63


Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations

portion of the assets must be re-classified as available for sale and held at fair value with any associated unrealized gain or loss recorded in surplus. To rebalance, assets may need to be sold in order to maintain the duration with the specified range, resulting in realizing a gain or loss from the sale. For U.S. GAAP, PRM investments are categorized as available for sale. The Company also uses foreign currency derivatives to hedge a portion of its U.S. dollar-denominated investments.(See Notes 3, 4 and 8 of the Notes to the Consolidated Financial Statements for additional information on the Company's investment strategies, hedging activities, and reinsurance, respectively.)

Aflac's SMR ratio remains high and reflects a strong capital and surplus position. As of December 31, 2019, Aflac Japan's SMR was 1,043%, compared with 965% at December 31, 2018. As part of the conversion of Aflac Japan from a branch to a subsidiary on April 1, 2018, the Company experienced an accounting-driven decline in the SMR of approximately 130 points, compared with the SMR as of December 31, 2017. The Company translatedexpects to be able to pay dividends out of certain accounts, thus restoring this accounting impact over an estimated three-year period.

The FSA has been conducting field testing with the insurance industry concerning the introduction of an economic value-based solvency regime. The field testing will assist the FSA in determining if an economic value-based solvency regime in Japan will be appropriate for the insurance industry.

Privacy and Cybersecurity Governance

The Company’s Board of Directors has adopted an information security policy directing management to establish and operate a global information security program with the goals of monitoring existing and emerging threats and ensuring that the Company’s information assets and data, and the data of its yen-denominated obligations usingcustomers, are appropriately protected from loss or theft. The Board has delegated oversight of the December 31, 2017, exchange rate. Actual future payments as reported in dollars will fluctuateCompany’s information security program to the Audit and Risk Committee. The Company’s senior officers, including its Global Security and Chief Information Security Officer, are responsible for the operation of the global information security program and regularly communicate with the Audit and Risk Committee on the program, including with respect to the state of the program, compliance with applicable regulations, current and evolving threats, and recommendations for changes in the yen/dollar exchange rate.information security program. The global information security program also includes a cybersecurity incident response plan that is designed to provide a management framework across Company functions for a coordinated assessment and response to potential security incidents. This framework establishes a protocol to report certain incidents to the Global Security and Chief Information Security Officer and other senior officers, with the goal of timely assessing such incidents, determining applicable disclosure requirements and communicating with the Audit and Risk Committee. The incident response plan directs the executive officers to report certain incidents immediately and directly to the Lead Non-Management Director.

Additional Information

Investors should note that the Company announces material financial information in its SEC filings, press releases and public conference calls. In accordance with SEC guidance, the Company may also use the Investor Relations section of the Company's website (http://investors.aflac.com) to communicate with investors about the Company. It is possible that the financial and other information the Company posts there could be deemed to be material information. The information on the Company's website is not part of this document. Further, the Company's references to website URLs are intended to be inactive textual references only.

CRITICAL ACCOUNTING ESTIMATES

The Company prepares its financial statements in accordance with U.S. GAAP. These principles are established primarily by the FASB. In this MD&A, references to U.S. GAAP issued by the FASB are derived from the FASB Accounting Standards Codification™ (ASC). The preparation of financial statements in conformity with U.S. GAAP requires the Company to make estimates based on currently available information when recording transactions resulting from business operations. The estimates that the Company deems to be most critical to an understanding of Aflac’s results of operations and financial condition are those related to the valuation of investments and derivatives, DAC, liabilities for future policy benefits and unpaid policy claims, and income taxes. The preparation and evaluation of these critical accounting estimates involve the use of various assumptions developed from management’s analyses and judgments. The application of these critical accounting estimates determines the values at which 94% of the Company's assets and 81% of its liabilities are reported as

6664




Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations

of December 31, 2019, and thus has a direct effect on net earnings and shareholders' equity. Subsequent experience or use of other assumptions could produce significantly different results.

Valuation of Investments, Including Derivatives, and Recognition of Other-than-Temporary Impairments

Aflac's investments, primarily consisting of debt and equity securities, include both publicly issued and privately issued securities. For publicly issued securities, the Company determines the fair values from quoted market prices readily available from public exchange markets and price quotes and valuations from third party pricing vendors. For the majority of privately issued securities within the Company's investment portfolio, a third party pricing vendor has developed valuation models that the Company utilizes to determine fair values. For the remaining privately issued securities, the Company uses non-binding price quotes from outside brokers.

The Company estimates the fair values of its securities on a monthly basis. The Company monitors the estimated fair values obtained from its pricing vendors and brokers for consistency from month to month, while considering current market conditions. The Company also periodically discusses with its pricing brokers and vendors the pricing techniques they use to monitor the consistency of their approach and periodically assess the appropriateness of the valuation level assigned to the values obtained from them. If a fair value appears unreasonable, the Company will re-examine the inputs and assess the reasonableness of the pricing data with the vendor. Additionally, the Company may compare the inputs to relevant market indices and other performance measurements. Based on management's analysis, the valuation is confirmed or may be revised if there is evidence of a more appropriate estimate of fair value based on available market data. The Company has performed verification of the inputs and calculations in any valuation models to confirm that the valuations represent reasonable estimates of fair value. Inputs used to value derivatives include, but are not limited to, interest rates, credit spreads, foreign currency forward and spot rates, and interest volatility.

The Company routinely reviews its investments that have experienced declines in fair value to determine if the decline is other than temporary. The identification of distressed investments, the determination of fair value if not publicly traded and the assessment of whether a decline is other than temporary involve significant management judgment. The Company must apply considerable judgment in determining the likelihood of the security recovering in value while the Company owns it. Factors that may influence this include the Company's assessment of the issuer’s ability to continue making timely payments of interest and principal, the overall level of interest rates and credit spreads, and other factors. This process requires consideration of risks, which can be controlled to a certain extent, such as credit risk, and risks which cannot be controlled, such as interest rate risk. Management updates its evaluations regularly and reflects impairment losses in the Company's net earnings or other comprehensive income, depending on the nature of the loss, as such evaluations are revised.

See Notes 1, 3, 4 and 5 of the Notes to the Consolidated Financial Statements for additional information.

Deferred Policy Acquisition Costs and Policy Liabilities

Insurance premiums for most of the Company's health and life policies, including cancer, accident, hospital, critical illness, dental, vision, term life, whole life, long-term care and disability, are recognized as revenue over the premium-paying periods of the contracts when due from policyholders. When revenues are reported, the related amounts of benefits and expenses are charged against such revenues, so that profits are recognized in proportion to premium revenues during the period the policies are expected to remain in force. This association is accomplished by means of annual additions to the liability for future policy benefits and the deferral and subsequent amortization of policy acquisition costs.

Premiums from the Company's products with limited-pay features, including term life, whole life, WAYS, and child endowment, are collected over a significantly shorter period than the period over which benefits are provided. Premiums for these products are recognized as revenue over the premium-paying periods of the contracts when due from policyholders. Any gross premium in excess of the net premium is deferred and recorded in earnings, such that profits are recognized in a constant relationship with insurance in force. Benefits are recorded as an expense when they are incurred. A liability for future policy benefits is recorded when premiums are recognized using the net premium method.

(1)Liability amounts are those reported on the consolidated balance sheet as of December 31, 2017.2019.
(2)The estimated payments due by period reflect future estimated cash payments to be made to policyholders and others for future policy benefits. These projected cash outflows are based on assumptions for future policy persistency, mortality, morbidity, and other assumptions comparable with the Company's experience, consider future premium receipts on current policies in force, and assume market growth and interest crediting consistent with assumptions used in amortizing deferred acquisition costs. These cash outflows are undiscounted with respect to interest and, as a result, the sum of the cash outflows shown for all years in the table of $244,395$244,884 exceeds the corresponding liability amount of $81,857.$90,335. The Company has made significant assumptions to determine the future estimated cash outflows related to the underlying policies and contracts. Due to the significance of the assumptions used, actual cash outflow amounts and timing will differ, possibly materially, from these estimates.

including securities lending transactions. See Notes 1, 3, and 4 of the Notes to the Consolidated Financial Statements for more information on the Company's securities lending and derivative activities. With the exception of disclosed activities in those referenced footnotes and the Risk Factors entitled, "The Company is exposed to foreign currency fluctuations in the yen/dollar exchange rate" and "Lack of availability of acceptable yen-denominated investments could adversely affect the Company's results of operations, financial position or liquidity," the Company is not aware of a trend, demand, commitment, event or uncertainty that would likely result in its liquidity increasing or decreasing by a material amount.
Consolidated Cash Flows


The Company translates cash flows for Aflac Japan's yen-denominated items into U.S. dollars using weighted-average exchange rates. In years when the yen weakens, translating yen into dollars causes fewer dollars to be reported. When the yen strengthens, translating yen into dollars causes more dollars to be reported.

Operating Activities

The principal cash inflows for the Company's insurance activities come from insurance premiums and investment income. The principal cash outflows are the result of policy claims, operating expenses, income tax, as well as interest expense. As a result of policyholder aging, claims payments are expected to gradually increase over the life of a policy. Therefore, future policy benefit reserves are accumulated in the early years of a policy and are designed to help fund future claims payments.
The Company expects its future cash flows from premiums and its investment portfolio to be sufficient to meet its cash needs for benefits and expenses. Consolidated cash flow from operations increased 2.4%decreased 9.3% in 2017,2019, compared with 2016. The following table summarizes operating cash flows by source for the years ended December 31.

The Company's investment objectives provide for liquidity primarily through the purchase of publicly traded investment-grade debt securities. Prudent portfolio management dictates that the Company attempts to match the duration of its assets with the duration of its liabilities. Currently, when the Company's fixed-maturity securities and perpetualfixed maturity securities mature, the proceeds may be reinvested at a yield below that required for the accretion of policy benefit liabilities on policies issued in earlier years. However, the long-term nature of the Company's business and its strong cash flows provide the Company with the ability to minimize the effect of mismatched durations and/or yields identified by various asset adequacy analyses. From time to time or when market opportunities arise, the Company disposes of selected fixed-maturity and perpetualfixed maturity securities that are available for sale to improve the duration matching of assets and liabilities, improve future investment yields, and/or re-balance its portfolio. As a result, dispositions before maturity can vary significantly from year to year. Dispositions before maturity were approximately 5%

As part of its overall corporate strategy, the Company has announced an increase in its commitment to the Aflac Ventures Fund from $250 million to $400 million, as opportunities emerge. These investments are included in equity securities or the other investments line in the consolidated balance sheets. The Aflac Ventures Fund is a subsidiary of Aflac Corporate Ventures which is reported in the Corporate and other segment. The central mission of Aflac Corporate Ventures is to support the organic growth and business development needs of Aflac Japan and Aflac U.S. with emphasis on digital applications designed to improve the customer experience, gain efficiencies, and develop new markets in an effort to enhance and defend long-term shareholder value.

As part of an arrangement with Federal Home Loan Bank of Atlanta (FHLB), Aflac U.S. obtains low-cost funding from FHLB supported by acceptable forms of collateral pledged by Aflac U.S. Aflac U.S. borrowed and repaid $217 million under this program during 2019.

Treasury Stock Issued
In 2018, the Company announced a change in its internal dividend policy which allows the Company to increase the proportion of regulatory earnings transferred from Aflac U.S. and Aflac Japan to the Parent Company. The Company intends to maintain higher than historical levels of capital and liquidity at the Parent Company with the goals of addressing the Company’s hedge costs and related potential need for collateral and mitigating against long-term weakening of the Japanese yen. Further, the Company plans to continue to maintain a portfolio of unhedged U.S. dollar based investments at Aflac Japan and consider whether the amount of such investments should be increased or decreased relative to the Company’s view of economic equity surplus in Aflac Japan in light of potentially rising hedge costs and other factors.

In January 2018,Operating Activities
The principal cash inflows for the boardCompany's insurance activities come from insurance premiums and investment income. The principal cash outflows are the result of directors announcedpolicy claims, operating expenses, income tax, as well as interest expense. As a 15.6%result of policyholder aging, claims payments are expected to gradually increase over the life of a policy. Therefore, future policy benefit reserves are accumulated in the quarterlyearly years of a policy and are designed to help fund future claims payments.
The Company expects its future cash dividend, effectiveflows from premiums and its investment portfolio to be sufficient to meet its cash needs for benefits and expenses. Consolidated cash flow from operations decreased 9.3% in 2019, compared with 2018.
Investing Activities
The Company's investment objectives provide for liquidity primarily through the purchase of publicly traded investment-grade debt securities. Prudent portfolio management dictates that the Company attempts to match the duration of its assets with the first quarterduration of 2018. The first quarter 2018 cash dividend of $.52 per share is payable on March 1, 2018, to shareholders of recordits liabilities. Currently, when the Company's fixed maturity securities mature, the proceeds may be reinvested at the close of business on February 21, 2018.

Regulatory Restrictions

Aflac and CAIC are domiciled in Nebraska and are subject to its regulations. The Nebraska Department of Insurance imposes certain limitations and restrictions on payments of dividends, management fees, loans and advances to the Parent Company. Under Nebraska insurance law, prior approval of the Nebraska Department of Insurance isa yield below that required for dividend distributions that exceed the greateraccretion of policy benefit liabilities on policies issued in earlier years. However, the net income from operations, which excludes net realized investment gains, for the previous year determined under statutory accounting principles, or 10% of statutory capital and surplus as of the previous year-end. In addition, the Nebraska insurance department must approve service arrangements and other transactions within the affiliated group of companies. These regulatory limitations are not expected to affect the level of management fees or dividends paid to the Parent Company. After the planned Japan branch conversion as early as April 1, 2018, Nebraska insurance department approval will not be needed for activities of the new subsidiary. (See below for discussion of restrictions imposed by Japanese insurance regulators.) A life insurance company’s statutory capital and surplus is determined according to rules prescribed by the National Association of Insurance Commissioners (NAIC), as modified by the insurance department in the insurance company’s state of domicile. Statutory accounting rules are different from U.S. GAAP and are intended to emphasize policyholder protection and company solvency. Similar laws apply in New York, the domiciliary jurisdiction of Aflac's New York insurance subsidiary. As of December 2016, CAIC was redomiciled from South Carolina to Nebraska.

The continued long-term growthnature of the Company's business may require increasesand its strong cash flows provide the Company with the ability to minimize the effect of mismatched durations and/or yields identified by various asset adequacy analyses. From time to time or when market opportunities arise, the Company disposes of selected fixed maturity securities that are available for sale to improve the duration matching of assets and liabilities, improve future investment yields, and/or re-balance its portfolio. As a result, dispositions before maturity can vary significantly from year to year.

As part of its overall corporate strategy, the Company has announced an increase in its commitment to the Aflac Ventures Fund from $250 million to $400 million, as opportunities emerge. These investments are included in equity securities or the other investments line in the statutory capital and surplusconsolidated balance sheets. The Aflac Ventures Fund is a subsidiary of its insurance operations. Aflac’s insurance operations may secure additional statutory capital through various sources, such as internally generated statutory earnings, capital contributions by the Parent Company from funds generated through debt or equity offerings, or reinsurance transactions. The NAIC’s risk-based capital (RBC) formulaAflac Corporate Ventures which is used by insurance regulators to help identify inadequately capitalized insurance companies. The RBC formula quantifies insurance risk, business risk, asset risk and interest rate risk by weighing the types and mixtures of risks inherentreported in the insurer’s operations. Aflac's company action level RBC ratio was 831% asCorporate and other segment. The central mission of December 31, 2017, comparedAflac Corporate Ventures is to support the organic growth and business development needs of Aflac Japan and Aflac U.S. with 894% at December 31, 2016.

As part of an arrangement with Federal Home Loan Bank of Atlanta (FHLB), Aflac U.S. obtains low-cost funding from FHLB supported by acceptable forms of collateral pledged by Aflac U.S. Aflac U.S. borrowed and repaid $217 million under this program during 2019. As of December 31, 2017, Aflac's total adjusted capital2019, Aflac U.S. had outstanding borrowings of $12.0 billion exceeded the company action level required capital and surplus of $1.4 billion by $10.6 billion. The U.S. Tax Act will have a negative impact on Aflac's U.S.-only RBC ratio. This reduction occurs as a result of writing down deferred tax assets and the increase$403 million reported in required capital due to the reduction in tax rates. However, Aflac expects to recover from this negative impact over a period of three to five years through additional statutory income, assuming that the additional income is fully retained.its balance sheet.


The maximum amount of dividends that can be paid to the Parent Company by Aflac without prior approval of Nebraska's director of insurance is the greater of the net income from operations, which excludes net realized investment gains, for the previous year determined under statutory accounting principles, or 10% of statutory capital and surplus as of the previous year-end. Dividends declared by Aflac during 2018 in excess of $2.6 billion would be considered extraordinary and require such approval. Subsequent to the Japan branch conversion to a subsidiary, the Company

The first tranche of the facility, which totaled ¥5.0 billion, bears interest at a rate per annum equal to the Tokyo interbank market rate (TIBOR), or alternate TIBOR, if applicable, plus the applicable TIBOR margin and will mature in September 2026. The applicable margin ranges between .30% and .70%, depending on the Parent Company's statutory capitaldebt ratings as of the date of determination. The second tranche, which totaled ¥25.0 billion, bears interest at a rate per annum equal to the TIBOR, or alternate TIBOR, if applicable, plus the applicable TIBOR margin and surplus.will mature in September 2029. The applicable margin ranges between .45% and 1.00%, depending on the Parent Company's debt ratings as of the date of determination.


In April 2019, ALIJ issued ¥30.0 billion (par value) of perpetual subordinated bonds. These bonds bear interest at a fixed rate of .963% per annum and then at six-month Euro Yen LIBOR plus an applicable spread on and after the day immediately following April 18, 2024. The NAIC considers its Solvency Modernization Initiative (SMI) process relatingbonds will be callable on each interest payment date on and after April 18, 2024. In November 2019, ALIJ amended the bonds to updatingchange their duration from perpetual to a stated maturity date of April 16, 2049 and to remove provisions that permitted ALIJ to defer payments of interest under certain circumstances.

In October 2018, the Parent Company issued $550 million of senior notes through a U.S. insurance solvency regulation frameworkpublic debt offering. The notes bear interest at a fixed rate of 4.750% per annum, payable semi-annually, and will mature in January 2049. These notes are redeemable at the Parent Company's option in whole at any time or in part from time to time at a redemption price equal to the greater of: (i) the aggregate principal amount of the notes to be ongoing. The SMI has focused on key issues such as capital requirements, governance and risk management, group supervision, reinsurance, statutory accounting and financial reporting matters. Many of these key issues have been finalized and/redeemed or are near completion; however,(ii) the NAIC still has some ongoing initiatives related to SMI, such as monitoring the international efforts on group capital requirements and group supervision as well as risk-based capital.In addition, the NAIC is also considering changes to investment risk factors. Any negative developments by the NAIC in these areas could result in increased capital requirements for the Company.

Aflac is subjectamount equal to the NAIC’s Own Risksum of the present values of the remaining scheduled payments for principal of and Solvency Assessment (ORSA), effective January 1, 2015. Throughinterest on the ORSA requirements, Aflac is expectednotes to regularly, no less than annually, conduct an ORSAbe redeemed, not including any portion of the payments of interest accrued as of such redemption date, discounted to assesssuch redemption date on a semiannual basis at the adequacyyield to maturity for a U.S.Treasury security with a maturity comparable to the remaining term of the notes, plus 25 basis points, plus in each case, accrued and unpaid interest on the principal amount of the notes to be redeemed to, but excluding, such redemption date.

In October 2018, the Parent Company issued three series of senior notes totaling ¥53.4 billion through a public debt offering under its U.S. shelf registration statement. The first series, which totaled ¥29.3 billion, bears interest at a fixed rate of 1.159% per annum, payable semi-annually, and will mature in October 2030. The second series, which totaled ¥15.2 billion, bears interest at a fixed rate of 1.488% per annum, payable semi-annually, and will mature in October 2033. The third series, which totaled ¥8.9 billion, bears interest at a fixed rate of 1.750% per annum, payable semi-annually, and will mature in October 2038. These notes may only be redeemed before maturity, in whole but not in part, upon the occurrence of certain changes affecting U.S. taxation, as specified in the indenture governing the terms of the issuance.

In November 2018, the Parent Company used the net proceeds from the October 2018 issuance of its risk management framework, and its current and estimated projected future solvency position; internally document the process and resultssenior notes to redeem $550 million of the assessment; and provide a confidential high-level ORSA Summary Report annually to the lead state commissioner if the insurer is a member of an insurance group. In November 2017, Aflac filed its ORSA report with the Nebraska Department of Insurance.Parent Company's 2.40% senior notes due in 2020.


In addition to limitations and restrictions imposed by U.S. insurance regulators, Japan’s Financial Services Agency (FSA) may not allow profit repatriations from Aflac Japan if the transfers would cause Aflac Japan to lack sufficient financial strength for the protection of policyholders. After the planned Japan branch conversion as early as April 1, 2018, the new Japan subsidiary will be required to meet certain financial criteria as governed by Japanese corporate law in order to provide dividends to the Parent Company. Under these criteria, dividend capacity at the Japan subsidiary will be defined as retained earnings plus other capital reserve less net after-tax unrealized losses on available-for-sale securities. These dividend capacity requirements are generally aligned with the solvency margin ratio (SMR). The FSA maintains its own solvency standard which is quantified through the SMR. Aflac Japan's SMR is sensitive to interest rate, credit spread, and foreign exchange rate changes, therefore the Company continues to evaluate alternatives for reducing this sensitivity. In the event of a rapid change in market risk conditions causing SMR to decline, the Company has two senior unsecured revolving credit facilities in the amounts of 100 billion yen and 55 billion yen, respectively, and a committed reinsurance facility in the amount of approximately 110 billion yen as a capital contingency plan. (See Notes 8 andSee Note 9 of the Notes to the Consolidated Financial Statements for additional information.)

The Company has already undertaken various measures to mitigate the sensitivity of Aflac Japan's SMR. For example, the Company employs policy reserve matching (PRM) investment strategies, which is a Japan-specific accounting treatment that reduces SMR interest rate sensitivity since PRM-designated investments are carried at amortized cost consistent with corresponding liabilities. In order for a PRM-designated asset to be held at amortized cost, there are certain criteria that must be maintained. The primary criteria relates to maintaining the duration of designated assets and liabilities within a specified tolerance range. If the duration difference is not maintained within the specified range without rebalancing, then a certain portion of the assets must be re-classified as available for sale and held at fair value with any associated unrealized gain or loss recorded in surplus. To rebalance, assets may need to be sold in order to maintain the duration with the specified range, resulting in realizing a gain or loss from the sale. For U.S. GAAP, PRM investments are categorized as available for sale. The Company also uses foreign currency derivatives to hedge a portion of its U.S. dollar-denominated investments.(See Notes 3, 4 and 8 of the Notes to the Consolidated Financial Statements for additionalfurther information on the Company's investment strategies, hedging activities,debt issuances discussed above.

The Company was in compliance with all of the covenants of its notes payable and reinsurance, respectively.)

Aslines of December 31, 2017, Aflac Japan's SMR was 1,064%, compared with 945%credit at December 31, 2016. Aflac's SMR ratio remains high2019.

Cash returned to shareholders through treasury stock purchases and reflects a strong capital and surplus position. The FSA has been conducting field testingdividends was $2.4 billion in 2019, compared with the insurance industry concerning the introduction of an economic value-based solvency regime. The field testing will assist the FSA$2.1 billion in determining if an economic value-based solvency regime in Japan will be appropriate for the insurance industry.2018.

In 2018, the Company announced a change in its internal dividend policy which allows the Company to increase the proportion of regulatory earnings transferred from Aflac U.S. and Aflac Japan to the Parent Company. The Company intends to maintain higher than historical levels of capital and liquidity at the Parent Company with the goals of addressing the Company’s hedge costs and related potential need for collateral and mitigating against long-term weakening of the Japanese yen. Further, the Company plans to continue to maintain a portfolio of unhedged U.S. dollar based investments at Aflac Japan and consider whether the amount of such investments should be increased or decreased relative to the Company’s view of economic equity surplus in Aflac Japan in light of potentially rising hedge costs and other factors. See the "Hedging Activity" subsection in this MD&A for more information.

In addition to cash and equivalents, the Company also maintains credit facilities, both intercompany and with external partners, and a number of other available tools to support liquidity needs on a global basis. In September 2018, the Parent Company filed a shelf registration statement with the SEC that allows the Company to issue an indefinite amount of debt securities, in one or more series, from time to time until September 2021. In August 2018, the Parent Company filed a shelf registration with Japanese regulatory authorities that allows the Parent Company to conduct public offerings of bonds in Japan, including yen-denominated Samurai notes, up to ¥200 billion or its equivalent through August 2020. The shelf registration statement is for possible public offerings in Japan, but the bonds issued under the shelf may be transferred by the bondholders to U.S. persons in compliance with U.S. law. The Company believes outside sources for additional debt and equity capital, if needed, will continue to be available. Additionally, as of December 31, 2019, the Parent Company and Aflac had four lines of credit with third parties and three intercompany lines of credit. For additional information, see Note 9 of the Notes to the Consolidated Financial Statements.

The primary uses of cash by the Parent Company are shareholder dividends, the repurchase of its common stock and interest on its outstanding indebtedness and operating expenses.

Liabilities for unrecognized tax benefits in the amount of $17 have been excluded from the tabular disclosure above because the timing of cash payment is not reasonably estimable.
(1)Liability amounts are those reported on the consolidated balance sheet as of December 31, 2019.
(2)The estimated payments due by period reflect future estimated cash payments to be made to policyholders and others for future policy benefits. These projected cash outflows are based on assumptions for future policy persistency, mortality, morbidity, and other assumptions comparable with the Company's experience, consider future premium receipts on current policies in force, and assume market growth and interest crediting consistent with assumptions used in amortizing deferred acquisition costs. These cash outflows are undiscounted with respect to interest and, as a result, the sum of the cash outflows shown for all years in the table of $244,884 exceeds the corresponding liability amount of $90,335. The Company has made significant assumptions to determine the future estimated cash outflows related to the underlying policies and contracts. Due to the significance of the assumptions used, actual cash outflow amounts and timing will differ, possibly materially, from these estimates.
(3)Includes assumptions as to the timing of policyholders reporting claims for prior periods and the amount of those claims. Actual amounts and timing of unpaid policy claims payments may differ significantly from the estimates above.

including securities lending transactions. See Notes 1, 3, and 4 of the Notes to the Consolidated Financial Statements for more information on the Company's securities lending and derivative activities. With the exception of disclosed activities in those referenced footnotes and the Risk Factors entitled, "The Company is exposed to foreign currency fluctuations in the yen/dollar exchange rate" and "Lack of availability of acceptable yen-denominated investments could adversely affect the Company's results of operations, financial position or liquidity," the Company is not aware of a trend, demand, commitment, event or uncertainty that would likely result in its liquidity increasing or decreasing by a material amount.
Consolidated Cash Flows

The Company had foreigntranslates cash flows for Aflac Japan's yen-denominated items into U.S. dollars using weighted-average exchange forwardsrates. In years when the yen weakens, translating yen into dollars causes fewer dollars to be reported. When the yen strengthens, translating yen into dollars causes more dollars to be reported.

Operating Activities
The principal cash inflows for the Company's insurance activities come from insurance premiums and optionsinvestment income. The principal cash outflows are the result of policy claims, operating expenses, income tax, as well as interest expense. As a result of policyholder aging, claims payments are expected to gradually increase over the life of a policy. Therefore, future policy benefit reserves are accumulated in the early years of a policy and are designed to help fund future claims payments.
The Company expects its future cash flows from premiums and its investment portfolio to be sufficient to meet its cash needs for benefits and expenses. Consolidated cash flow from operations decreased 9.3% in 2019, compared with 2018.
Investing Activities
The Company's investment objectives provide for liquidity primarily through the purchase of publicly traded investment-grade debt securities. Prudent portfolio management dictates that the Company attempts to match the duration of its assets with the duration of its liabilities. Currently, when the Company's fixed maturity securities mature, the proceeds may be reinvested at a yield below that required for the accretion of policy benefit liabilities on policies issued in earlier years. However, the long-term nature of the Company's business and its strong cash flows provide the Company with the ability to minimize the effect of mismatched durations and/or yields identified by various asset adequacy analyses. From time to time or when market opportunities arise, the Company disposes of selected fixed maturity securities that are available for sale to improve the duration matching of assets and liabilities, improve future investment yields, and/or re-balance its portfolio. As a result, dispositions before maturity can vary significantly from year to year.

As part of its overall corporate strategy, the Company has announced an increase in its commitment to the Aflac Ventures Fund from $250 million to $400 million, as opportunities emerge. These investments are included in equity securities or the other investments line in the consolidated balance sheets. The Aflac Ventures Fund is a subsidiary of Aflac Corporate Ventures which is reported in the Corporate and other segment. The central mission of Aflac Corporate Ventures is to support the organic growth and business development needs of Aflac Japan and Aflac U.S. with emphasis on digital applications designed to improve the customer experience, gain efficiencies, and develop new markets in an effort to enhance and defend long-term shareholder value.

As part of an economic hedgearrangement with Federal Home Loan Bank of Atlanta (FHLB), Aflac U.S. obtains low-cost funding from FHLB supported by acceptable forms of collateral pledged by Aflac U.S. Aflac U.S. borrowed and repaid $217 million under this program during 2019. As of December 31, 2019, Aflac U.S. had outstanding borrowings of $403 million reported in its balance sheet.

Financing Activities

Consolidated cash used by financing activities was $1.7 billion in 2019 and $1.6 billion in 2018.

In December 2019, the Parent Company issued four series of senior notes totaling ¥38.0 billion through a public debt offering under its U.S. shelf registration statement. The first series, which totaled ¥12.6 billion, bears interest at a fixed rate of .500% per annum, payable semi-annually, and will mature in December 2029. The second series, which totaled ¥9.3 billion, bears interest at a fixed rate of .843% per annum, payable semi-annually, and will mature in December 2031.

The fourth series, which totaled ¥6.3 billion, bears interest at a fixed rate of 1.122% per annum, payable semi-annually, and will mature in December 2039. These notes may only be redeemed before maturity, in whole but not in part, upon the occurrence of certain changes affecting U.S. taxation, as specified in the indenture governing the terms of the issuance.

In September 2019, the Parent Company renewed a ¥30.0 billion senior term loan facility. The first tranche of the facility, which totaled ¥5.0 billion, bears interest at a rate per annum equal to the Tokyo interbank market rate (TIBOR), or alternate TIBOR, if applicable, plus the applicable TIBOR margin and will mature in September 2026. The applicable margin ranges between .30% and .70%, depending on the Parent Company's debt ratings as of the date of determination. The second tranche, which totaled ¥25.0 billion, bears interest at a rate per annum equal to the TIBOR, or alternate TIBOR, if applicable, plus the applicable TIBOR margin and will mature in September 2029. The applicable margin ranges between .45% and 1.00%, depending on the Parent Company's debt ratings as of the date of determination.

In April 2019, ALIJ issued ¥30.0 billion (par value) of perpetual subordinated bonds. These bonds bear interest at a fixed rate of .963% per annum and then at six-month Euro Yen LIBOR plus an applicable spread on and after the day immediately following April 18, 2024. The bonds will be callable on each interest payment date on and after April 18, 2024. In November 2019, ALIJ amended the bonds to change their duration from perpetual to a stated maturity date of April 16, 2049 and to remove provisions that permitted ALIJ to defer payments of interest under certain circumstances.

In October 2018, the Parent Company issued $550 million of senior notes through a U.S. public debt offering. The notes bear interest at a fixed rate of 4.750% per annum, payable semi-annually, and will mature in January 2049. These notes are redeemable at the Parent Company's option in whole at any time or in part from time to time at a redemption price equal to the greater of: (i) the aggregate principal amount of the notes to be redeemed or (ii) the amount equal to the sum of the present values of the remaining scheduled payments for principal of and interest on the notes to be redeemed, not including any portion of the payments of interest accrued as of such redemption date, discounted to such redemption date on a semiannual basis at the yield to maturity for a U.S.Treasury security with a maturity comparable to the remaining term of the notes, plus 25 basis points, plus in each case, accrued and unpaid interest on the principal amount of the notes to be redeemed to, but excluding, such redemption date.

In October 2018, the Parent Company issued three series of senior notes totaling ¥53.4 billion through a public debt offering under its U.S. shelf registration statement. The first series, which totaled ¥29.3 billion, bears interest at a fixed rate of 1.159% per annum, payable semi-annually, and will mature in October 2030. The second series, which totaled ¥15.2 billion, bears interest at a fixed rate of 1.488% per annum, payable semi-annually, and will mature in October 2033. The third series, which totaled ¥8.9 billion, bears interest at a fixed rate of 1.750% per annum, payable semi-annually, and will mature in October 2038. These notes may only be redeemed before maturity, in whole but not in part, upon the occurrence of certain changes affecting U.S. taxation, as specified in the indenture governing the terms of the issuance.

In November 2018, the Parent Company used the net proceeds from the October 2018 issuance of its senior notes to redeem $550 million of the Parent Company's 2.40% senior notes due in 2020.

See Note 9 of the Notes to the Consolidated Financial Statements for further information on the debt issuances discussed above.

The Company was in compliance with all of the covenants of its notes payable and lines of credit at December 31, 2019.

Cash returned to shareholders through treasury stock purchases and dividends was $2.4 billion in 2019, compared with $2.1 billion in 2018.

Regulatory Restrictions

Aflac, CAIC and TOIC are domiciled in Nebraska and are subject to its regulations. Subsequent to the Japan branch conversion to a subsidiary, Aflac Japan is domiciled in Japan and subject to local regulations. The Nebraska Department of Insurance imposes certain limitations and restrictions on payments of dividends, management fees, loans and advances to the Parent Company. Under Nebraska insurance law, prior approval of the Nebraska Department of Insurance is required for dividend distributions that exceed the greater of the net income from operations, which excludes net realized investment gains, for the previous year determined under statutory accounting principles, or 10% of statutory capital and surplus as of the previous year-end. In addition, the Nebraska insurance department must approve service arrangements and other transactions within the affiliated group of companies. These regulatory limitations are not expected to affect the level of management fees or dividends paid to the Parent Company. (See below for discussion of restrictions imposed by Japanese insurance regulators.) A life insurance company’s statutory capital and surplus is determined according to rules prescribed by the NAIC, as modified by the insurance department in the insurance company’s state of domicile. Statutory accounting rules are different from U.S. GAAP and are intended to emphasize policyholder protection and company solvency. Similar laws apply in New York, the domiciliary jurisdiction of Aflac New York.

Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations

The continued long-term growth of the Company's business may require increases in the statutory capital and surplus of its insurance operations. Aflac’s insurance operations may secure additional statutory capital through various sources, such as internally generated statutory earnings, capital contributions by the Parent Company from funds generated through debt or equity offerings, or reinsurance transactions. The NAIC’s RBC formula is used by insurance regulators to help identify inadequately capitalized insurance companies. The RBC formula quantifies insurance risk, on 90.9business risk, asset risk and interest rate risk by weighing the types and mixtures of risks inherent in the insurer’s operations.

Aflac's company action level RBC ratio was 539% as of December 31, 2019, compared with 560% at December 31, 2018. Aflac’s RBC ratio remains high and reflects a strong capital and surplus position. As of December 31, 2019, Aflac's total adjusted capital of $2.2 billion yenexceeded the company action level required capital and surplus of profit repatriation received$.4 billion by $1.8 billion. With the announcement of the Japan branch conversion to a subsidiary, we had announced our intention to remove excess capital out of Aflac, targeting a 500% RBC by the end of 2019. As of December 31, 2019, the Company has completed the RBC drawdown plan and has moved $1.75 billion of capital from Aflac to the Parent Company, supporting the Company's capital deployment and risk management activities.

The maximum amount of dividends that can be paid to the Parent Company by Aflac, CAIC and TOIC without prior approval of Nebraska's director of insurance is the greater of the net income from operations, which excludes net realized investment gains, for the previous year determined under statutory accounting principles, or 10% of statutory capital and surplus as of the previous year-end. Dividends declared by Aflac during 2020 in excess of $864 million would be considered extraordinary and require such approval. Following the Japan branch conversion to a subsidiary, the Company used extraordinary dividends as needed to actively manage to appropriate RBC levels that are lower yet sufficient to maintain ratings and support prudent capital management. Similar laws apply in 2017, resulting in $1 million less funds received whenNew York, the yen were exchanged into dollars relative to what would have been received at the then-current exchange rate.

For additional information on regulatory restrictions on dividends, profit repatriations and other transfers, seedomiciliary jurisdiction of Aflac New York. See Note 13 of the Notes to the Consolidated Financial Statements.Statements for information regarding the impact of permitted practices by the Nebraska Department of Insurance on the Company's statutory capital and surplus.


The NAIC considers its Solvency Modernization Initiative (SMI) process relating to updating the U.S. insurance solvency regulation framework to be ongoing. The SMI has focused on key issues such as capital requirements, governance and risk management, group supervision, reinsurance, statutory accounting and financial reporting matters. Many of these key issues have been finalized and/or are near completion; however, the NAIC still has some ongoing initiatives related to SMI, such as monitoring the international efforts on group capital requirements as well as RBC.In addition, the NAIC is also considering changes to investment risk factors. Any negative developments by the NAIC in these areas could result in increased capital requirements for the Company.

Aflac is subject to the NAIC’s Own Risk and Solvency Assessment (ORSA). Through the ORSA requirements, Aflac is expected to regularly, no less than annually, conduct an ORSA to assess the adequacy of its risk management framework, and its current and estimated projected future solvency position; internally document the process and results of the assessment; and provide a confidential high-level ORSA Summary Report annually to the lead state commissioner if the insurer is a member of an insurance group. In November 2019, Aflac filed its ORSA report with the Nebraska Department of Insurance.

In addition to limitations and restrictions imposed by U.S. insurance regulators, after the Japan branch conversion on April 1, 2018, the new Japan subsidiary is required to meet certain financial criteria as governed by Japanese corporate law in order to provide dividends to the Parent Company. Under these criteria, dividend capacity at the Japan subsidiary is basically defined as total equity excluding common stock, accumulated other comprehensive income amounts, capital reserves (representing statutorily required amounts in Japan) but reduced for net after-tax unrealized losses on available-for-sale securities. These dividend capacity requirements are generally aligned with the SMR. Japan's FSA maintains its own solvency standard which is quantified through the SMR. Aflac Japan's SMR is sensitive to interest rate, credit spread, and foreign exchange rate changes, therefore the Company continues to evaluate alternatives for reducing this sensitivity. In the event of a rapid change in market risk conditions causing SMR to decline, the Company has one senior unsecured revolving credit facility in the amount of ¥100 billion and a committed reinsurance facility in the amount of approximately ¥110 billion as a capital contingency plan. Additionally, the Company could take action to enter into derivatives on unhedged U.S. dollar-denominated investments with foreign currency options or forwards. See Notes 8 and 9 of the Notes to the Consolidated Financial Statements for additional information.

The Company has already undertaken various measures to mitigate the sensitivity of Aflac Japan's SMR. For example, the Company employs policy reserve matching (PRM) investment strategies, which is a Japan-specific accounting treatment that reduces SMR interest rate sensitivity since PRM-designated investments are carried at amortized cost consistent with corresponding liabilities. In order for a PRM-designated asset to be held at amortized cost, there are certain criteria that must be maintained. The primary criteria relates to maintaining the duration of designated assets and liabilities within a specified tolerance range. If the duration difference is not maintained within the specified range without rebalancing, then a certain

63


Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations

portion of the assets must be re-classified as available for sale and held at fair value with any associated unrealized gain or loss recorded in surplus. To rebalance, assets may need to be sold in order to maintain the duration with the specified range, resulting in realizing a gain or loss from the sale. For U.S. GAAP, PRM investments are categorized as available for sale. The Company also uses foreign currency derivatives to hedge a portion of its U.S. dollar-denominated investments.(See Notes 3, 4 and 8 of the Notes to the Consolidated Financial Statements for additional information on the Company's investment strategies, hedging activities, and reinsurance, respectively.)

Aflac's SMR ratio remains high and reflects a strong capital and surplus position. As of December 31, 2019, Aflac Japan's SMR was 1,043%, compared with 965% at December 31, 2018. As part of the conversion of Aflac Japan from a branch to a subsidiary on April 1, 2018, the Company experienced an accounting-driven decline in the SMR of approximately 130 points, compared with the SMR as of December 31, 2017. The Company expects to be able to pay dividends out of certain accounts, thus restoring this accounting impact over an estimated three-year period.

The FSA has been conducting field testing with the insurance industry concerning the introduction of an economic value-based solvency regime. The field testing will assist the FSA in determining if an economic value-based solvency regime in Japan will be appropriate for the insurance industry.

Privacy and Cybersecurity Governance

The Company’s Board of Directors has adopted an information security policy directing management to establish and operate a global information security program with the goals of monitoring existing and emerging threats and ensuring that the Company’s information assets and data, and the data of its customers, are appropriately protected from loss or theft. The Board has delegated oversight of the Company’s information security program to the Audit and Risk Committee. The Company’s senior officers, including its Global Security and Chief Information Security Officer, are responsible for the operation of the global information security program and regularly communicate with the Audit and Risk Committee on the program, including with respect to the state of the program, compliance with applicable regulations, current and evolving threats, and recommendations for changes in the information security program. The global information security program also includes a cybersecurity incident response plan that is designed to provide a management framework across Company functions for a coordinated assessment and response to potential security incidents. This framework establishes a protocol to report certain incidents to the Global Security and Chief Information Security Officer and other senior officers, with the goal of timely assessing such incidents, determining applicable disclosure requirements and communicating with the Audit and Risk Committee. The incident response plan directs the executive officers to report certain incidents immediately and directly to the Lead Non-Management Director.

CRITICAL ACCOUNTING ESTIMATES

The Company prepares its financial statements in accordance with U.S. GAAP. These principles are established primarily by the FASB. In this MD&A, references to U.S. GAAP issued by the FASB are derived from the FASB Accounting Standards Codification™ (ASC). The preparation of financial statements in conformity with U.S. GAAP requires the Company to make estimates based on currently available information when recording transactions resulting from business operations. The estimates that the Company deems to be most critical to an understanding of Aflac’s results of operations and financial condition are those related to the valuation of investments and derivatives, DAC, liabilities for future policy benefits and unpaid policy claims, and income taxes. The preparation and evaluation of these critical accounting estimates involve the use of various assumptions developed from management’s analyses and judgments. The application of these critical accounting estimates determines the values at which 94% of the Company's assets and 81% of its liabilities are reported as

64


Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations

of December 31, 2019, and thus has a direct effect on net earnings and shareholders' equity. Subsequent experience or use of other assumptions could produce significantly different results.

Valuation of Investments, Including Derivatives, and Recognition of Other-than-Temporary Impairments

Aflac's investments, primarily consisting of debt and equity securities, include both publicly issued and privately issued securities. For publicly issued securities, the Company determines the fair values from quoted market prices readily available from public exchange markets and price quotes and valuations from third party pricing vendors. For the majority of privately issued securities within the Company's investment portfolio, a third party pricing vendor has developed valuation models that the Company utilizes to determine fair values. For the remaining privately issued securities, the Company uses non-binding price quotes from outside brokers.

The Company estimates the fair values of its securities on a monthly basis. The Company monitors the estimated fair values obtained from its pricing vendors and brokers for consistency from month to month, while considering current market conditions. The Company also periodically discusses with its pricing brokers and vendors the pricing techniques they use to monitor the consistency of their approach and periodically assess the appropriateness of the valuation level assigned to the values obtained from them. If a fair value appears unreasonable, the Company will re-examine the inputs and assess the reasonableness of the pricing data with the vendor. Additionally, the Company may compare the inputs to relevant market indices and other performance measurements. Based on management's analysis, the valuation is confirmed or may be revised if there is evidence of a more appropriate estimate of fair value based on available market data. The Company has performed verification of the inputs and calculations in any valuation models to confirm that the valuations represent reasonable estimates of fair value. Inputs used to value derivatives include, but are not limited to, interest rates, credit spreads, foreign currency forward and spot rates, and interest volatility.

The Company routinely reviews its investments that have experienced declines in fair value to determine if the decline is other than temporary. The identification of distressed investments, the determination of fair value if not publicly traded and the assessment of whether a decline is other than temporary involve significant management judgment. The Company must apply considerable judgment in determining the likelihood of the security recovering in value while the Company owns it. Factors that may influence this include the Company's assessment of the issuer’s ability to continue making timely payments of interest and principal, the overall level of interest rates and credit spreads, and other factors. This process requires consideration of risks, which can be controlled to a certain extent, such as credit risk, and risks which cannot be controlled, such as interest rate risk. Management updates its evaluations regularly and reflects impairment losses in the Company's net earnings or other comprehensive income, depending on the nature of the loss, as such evaluations are revised.

See Notes 1, 3, 4 and 5 of the Notes to the Consolidated Financial Statements for additional information.

Deferred Policy Acquisition Costs and Policy Liabilities

Insurance premiums for most of the Company's health and life policies, including cancer, accident, hospital, critical illness, dental, vision, term life, whole life, long-term care and disability, are recognized as revenue over the premium-paying periods of the contracts when due from policyholders. When revenues are reported, the related amounts of benefits and expenses are charged against such revenues, so that profits are recognized in proportion to premium revenues during the period the policies are expected to remain in force. This association is accomplished by means of annual additions to the liability for future policy benefits and the deferral and subsequent amortization of policy acquisition costs.

Premiums from the Company's products with limited-pay features, including term life, whole life, WAYS, and child endowment, are collected over a significantly shorter period than the period over which benefits are provided. Premiums for these products are recognized as revenue over the premium-paying periods of the contracts when due from policyholders. Any gross premium in excess of the net premium is deferred and recorded in earnings, such that profits are recognized in a constant relationship with insurance in force. Benefits are recorded as an expense when they are incurred. A liability for future policy benefits is recorded when premiums are recognized using the net premium method.

Deferred Policy Acquisition Costs

The calculation of DAC and the liability for future policy benefits requires the use of estimates based on sound actuarial valuation techniques. For new policy issues, the Company reviews its actuarial assumptions and deferrable acquisition costs each year and revise them when necessary to more closely reflect recent experience and studies of actual acquisition costs. For policies in force, the Company evaluates DAC by major product groupings to determine that they are recoverable from future revenues, and any amounts determined not to be recoverable are charged against net earnings. See Note 6 of the Notes to the Consolidated Financial Statements for a detail of the DAC activity for the past two years.

Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations


Policy Liabilities

The Company's policy liabilities, which are determined in accordance with applicable guidelines as defined under U.S. GAAP and Actuarial Standards of Practice, include two components that involve analysis and judgment: future policy benefits and unpaid policy claims, which accounted for 85% and 4% of total policy liabilities as of December 31, 2019, respectively.

Future policy benefits provide for claims that will occur in the future and are generally calculated as the present value of future expected benefits to be incurred less the present value of future expected net benefit premiums. The Company calculates future policy benefits based on assumptions of morbidity, mortality, persistency and interest. These assumptions are generally established at the time a policy is issued. The assumptions used in the calculations are closely related to those used in developing the gross premiums for a policy. As required by U.S. GAAP, the Company also includes a provision for adverse deviation, which is intended to accommodate adverse fluctuations in actual experience.

Unpaid policy claims include those claims that have been incurred and are in the process of payment as well as an estimate of those claims that have been incurred but have not yet been reported to the Company. The Company computes unpaid policy claims on a non-discounted basis using statistical analyses of historical claims payments, adjusted for current trends and changed conditions. The Company updates the assumptions underlying the estimate of unpaid policy claims regularly and incorporates its historical experience as well as other data that provides information regarding the Company's outstanding liability.

The Company's insurance products provide fixed-benefit amounts per occurrence that are not subject to medical-cost inflation. Furthermore, the Company's business is widely dispersed in both the U.S. and Japan. This geographic dispersion and the nature of the Company's benefit structure mitigate the risk of a significant unexpected increase in claims payments due to epidemics and events of a catastrophic nature. Claims incurred under Aflac's policies are generally reported and paid in a relatively short time frame. The unpaid claims liability is sensitive to morbidity assumptions, in particular, severity and frequency of claims. Severity is the ultimate size of a claim, and frequency is the number of claims incurred. The Company's claims experience is primarily related to the demographics of its policyholders.

As a part of its established financial reporting and accounting practices and controls, the Company performs detailed annual actuarial reviews of its policyholder liabilities (gross premium valuation analysis) and reflects the results of those reviews in its results of operations and financial condition as required by U.S. GAAP. For Aflac Japan, the Company’s annual reviews in 2019 and 2018 indicated no need to strengthen liabilities associated with policies in Japan. For Aflac U.S., the Company's annual reviews in 2019 and 2018 indicated no need to strengthen liabilities associated with policies in the U.S.

The table below reflects the growth of the future policy benefits liability for the years ended December 31.

The growth of the future policy benefits liability in yen for Aflac Japan and in dollars for Aflac U.S. has been due to the aging of the Company's in-force block of business and the addition of new business.

In computing the estimate of unpaid policy claims, the Company considers many factors, including the benefits and amounts available under the policy; the volume and demographics of the policies exposed to claims; and internal business practices, such as incurred date assignment and current claim administrative practices. The Company monitors these conditions closely and make adjustments to the liability as actual experience emerges. Claim levels are generally stable from period to period; however, fluctuations in claim levels may occur. In calculating the unpaid policy claim liability, the Company

66


Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations

does not calculate a range of estimates. The following table shows the expected sensitivity of the unpaid policy claims liability as of December 31, 2019, to changes in severity and frequency of claims.

Other policy liabilities, which accounted for 11% of total policy liabilities as of December 31, 2019, consisted primarily of annuity and unearned premium reserves, and discounted advance premiums on deposit from policyholders in conjunction with their purchase of certain Aflac Japan insurance products. These advanced premiums are deferred upon collection and recognized as premium revenue over the contractual premium payment period. Advanced premiums represented 24% and 29% of the December 31, 2019 and 2018 other policy liabilities balances, respectively. See the Aflac Japan segment subsection of this MD&A for further information.

Income Taxes

Income tax provisions are generally based on pretax earnings reported for financial statement purposes, which differ from those amounts used in preparing the Company's income tax returns. Deferred income taxes are recognized for temporary differences between the financial reporting basis and income tax basis of assets and liabilities, based on enacted tax laws and statutory tax rates applicable to the periods in which the Company expects the temporary differences to reverse. The evaluation of a tax position in accordance with U.S. GAAP is a two-step process. Under the first step, the enterprise determines whether it is more likely than not that a tax position will be sustained upon examination by taxing authorities. The second step is measurement, whereby a tax position that meets the more-likely-than-not recognition threshold is measured to determine the amount of benefit to recognize in the financial statements. A valuation allowance is established for deferred tax assets when it is more likely than not that an amount will not be realized. The determination of a valuation allowance for deferred tax assets requires management to make certain judgments and assumptions.

In evaluating the ability to recover deferred tax assets, the Company's management considers all available evidence, including taxable income in open carry back years, the existence of cumulative losses in the most recent years, forecasted earnings, future taxable income exclusive of reversing temporary differences and carryforwards, future taxable temporary difference reversals, and prudent and feasible tax planning strategies. In the event the Company determines it is not more likely than not that it will be able to realize all or part of its deferred tax assets in the future, a valuation allowance would be charged to earnings in the period such determination is made. Likewise, if it is later determined that it is more likely than not that those deferred tax assets would be realized, the previously provided valuation allowance would be reversed. Future economic conditions and market volatility, including increases in interest rates or widening credit spreads, can adversely impact the Company’s tax planning strategies and in particular the Company’s ability to utilize tax benefits on previously recognized capital losses. The Company's judgments and assumptions are subject to change given the inherent uncertainty in predicting future performance and specific industry and investment market conditions.
For additional information on income tax, see Note 10 of the Notes to the Consolidated Financial Statements presented in this report.

Future Adoption of Accounting Standard for Long-Duration Insurance Contracts

In August 2018, the FASB issued ASU 2018-12, “Financial Services - Insurance, Targeted Improvements to the Accounting for Long-Duration Contracts.” The update, which is expected to significantly change how insurers account for long-duration contracts, amends existing recognition, measurement, presentation, and disclosure requirements applicable to the Company. Issues addressed in the new guidance include: 1) a requirement to review and, if there is a change, update cash flow assumptions for the liability for future policy benefits at least annually, and to update the discount rate assumption quarterly, 2) accounting for market risk benefits at fair value, 3) simplified amortization for deferred acquisition costs, and 4) enhanced financial statement presentation and disclosures. In November 2019, the FASB issued ASU 2019-09, “Financial Services - Insurance (Topic 944): Effective Date”, which defers the effective date of ASU 2018-12 for all entities. The amendments are effective for public business entities that meet the definition of an SEC filer, excluding entities eligible to be smaller reporting companies as defined by the SEC,for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2021. Early application of the amendments is permitted, however, the Company does not expect to early adopt the updated standard.

The Company is thoroughly evaluating the impact of ASU 2018-12 adoption and expects it will have a significant impact on the Company’s reported financial position, results of operations, and disclosures under U.S. GAAP accounting. The Company anticipates that the requirement to update assumptions for liability for future policy benefits will have a significant impact on its results of operations, systems, processes and controls while the requirement to update the discount rate will have a significant impact on its AOCI and equity. The Company currently has no products with market risk benefits.

There are two permitted transition methods upon adoption. The default transition method is a modified retrospective approach or companies may elect to apply the amendments using a full retrospective approach.

Under the modified retrospective method, the opening reserve balance at the transition date, January 1, 2020, would generally be the same as the closing balance before transition; however, it would be updated for changes in the discount rate required under the new guidance.

Regardless of the transition method selected, the new guidance requires that discount rates used for discounting of insurance liabilities be initially adjusted on the adoption date and subsequently at each reporting period to the market levels for the upper-medium-grade (low credit risk) fixed income instrument yields (single-A in the currency of the underlying insurance contract) reflecting the duration of the company’s insurance liabilities. Long duration of the Company’s third-sector insurance liabilities in Japan coupled with limited-to-no-liquidity of the Japanese long-dated fixed-income market creates challenges in application of the market-based discount rate guidance and will require the Company to apply significant judgments in designing discount rate methodologies for its Japanese third-sector liabilities. The update of the discount rate would be recognized in AOCI under both transition methods.

Under the full retrospective method, the Company would restate all historical periods based upon actual historical experience as of contract inception and its updated view of the contractual cash flow projections at transition. A cumulative catch-up adjustment to opening retained earnings would be recognized to reflect the actual experience and updated projections. Companies are permitted to apply a full retrospective transition approach if actual historical information is available for all contracts that will be affected by the new guidance.

The Company has selected the modified retrospective transition method.

The Company expects that under either transition method, the impact to its reported financial statements under U.S. GAAP will be greatly influenced by the nature of the Company’s business model. Adoption of the new guidance will reflect the Company’s concentration in Japan third-sector business, in particular cancer insurance, with respect to which the duration of liabilities is materially longer than asset durations, while Japan’s aggregate block of business continues to see favorable experience from mortality, morbidity, and expenses. Under the modified retrospective method, the impact of a low discount rate applied to long-duration third sector liabilities is recognized at adoption, while associated favorable morbidity margins are recognized over time thus driving a pronounced timing impact to U.S. GAAP equity. In addition, with respect to the Japan segment, the Company maintains a large portfolio of assets designated as held-to-maturity (HTM) as a strategy to reduce capital (solvency margin ratio or SMR) volatility. In a low interest rate environment, such as presently exists in Japan, assets designated as HTM that were purchased in a higher interest rate environment have significant embedded gains not reflected in AOCI (HTM securities are carried at amortized cost under U.S. GAAP), which serves as an economic offset to a low discount rate applied to policy liabilities. At December 31, 2019, the Company’s HTM portfolio was $30.1 billion at amortized cost and had $7.5 billion in net unrealized gains. Pursuant to the implementation of ASU 2019-04, ”Codification Improvements to Topic 326, Financial Instruments - Credit Losses, Topic 815, Derivatives and Hedging, and Topic 825, Financial

68


Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations

Instruments” (see Note 1 for additional details of this ASU), effective on January 1, 2020, the Company anticipates the reclassification of approximately $6.9 billion (at amortized cost) of pre-payable fixed maturity securities from the HTM to the available-for-sale (AFS) category. This reclassification is expected to result in recording in AOCI a net unrealized gain of approximately $800 million on an after-tax basis based on the securities’ fair values on the reclassification date.After adoption of ASU 2018-12, the Company also expects net earnings and net earnings per share (which were $3.3 billion and $4.43 per diluted share, respectively, in 2019) to reflect larger quarterly fluctuations due to the new requirement to update assumptions for liability for future policy benefits.

As an example of the potential impact of the new guidance, and for illustrative purposes only, under the modified retrospective method and in a low interest rate environment, the Company would expect AOCI (which was $6.6 billion at December 31, 2019) to significantly decline upon adoption and to thereafter reflect larger quarterly fluctuations due to the new requirement to quarterly adjust discount rates. Conversely, in a higher interest rate environment, and assuming adoption of the modified retrospective method, the Company would expect AOCI to decline less or even increase (depending on the specifics of the interest rate environment), as well as to reflect quarterly fluctuations. Under the full retrospective method, the Company would expect lesser declines or increases in total equity upon adoption compared to the modified retrospective method due to the potential offsetting effect from updating experience and cash flow projections.

The ultimate impact on these items from the Company’s implementation of the updated standard is subject to assessments that are dependent on many variables, including but not limited to (i) the transition method selected by the Company, (ii) how certain aspects of the new standard will be interpreted and implemented by the Company and other similar companies, such as (but not limited to) amortization of deferred acquisition costs and selection of discounting methodologies and inputs, as well as establishment of policies, processes and controls for setting, monitoring and periodically updating reserve assumptions, and (iii) changes in the interest rate environment in the US and Japan. The impact on transition under the modified retrospective method will be driven by updating discount rates that will increase reserves and lower AOCI by the corresponding amount.

The Company expects that while the adoption of this new accounting guidance will affect the Company’s financial statements under U.S. GAAP, it will not impact financial statements for Aflac Japan under FSA requirements or for Aflac U.S. under applicable statutory requirements. Therefore, the Company does not expect adoption of the updated standard to impact its overall cash flows, subsidiaries’ dividend capacity or their ability to meet applicable regulatory capital standards, nor does the Company anticipate adoption to affect its existing debt covenants or strategies for capital deployment.
New Accounting Pronouncements

During the last three years, various accounting standard-setting bodies have been active in soliciting comments and issuing statements, interpretations and exposure drafts. For information on new accounting pronouncements and the impact, if any, on the Company's financial position or results of operations, see Note 1 of the Notes to the Consolidated Financial Statements.
ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
The Company is exposed primarily to the following types of market risks: currency risk, interest rate risk, credit risk and equity risk. Fluctuations in these factors could impact the Company’s consolidated results of operations or financial condition. The Company regularly monitors its market risks and uses a variety of strategies to manage its exposure
to these market risks.


Currency Risk


Aflac Japan

The functional currency of Aflac Japan's insurance operations is the Japanese yen. Aflac Japan’s premiums and approximately halfa significant portion of its investment income are received in yen, and its claims and most expenses are paid in yen. Aflac Japan purchases yen-denominated assets and U.S. dollar-denominated assets, which may be hedged to yen, to support yen-denominated policy liabilities. These and other yen-denominated financial statement items are, however, translated into U.S. dollars for financial reporting purposes. Most of Aflac Japan's cash and liabilities are yen-denominated. Aflac Japan's yen-denominated investments consisted of fixed income securities of $71.8 billion, at amortized cost, and equity securities of $561 million, at cost, at December 31, 2017. However, Aflac Japan also owns

The Company engages in hedging activities to mitigate certain currency risks from holding U.S. dollar-denominated investments in Aflac Japan. However, this hedging program in turn poses a countervailing long-term risk of $9.3 billion,loss on hedging currency derivatives under the long-term scenario of weakening yen, and related derivative rollover risk that could amplify hedge cost in unfavorable market conditions and significantly increase liquidity requirements to support negative derivative

Item 7A. Quantitative and Qualitative Disclosures About Market Risk

settlements. Additionally, as discussed in detail in the Risk Factors section titled “Lack of availability of acceptable yen-denominated investments could adversely affect the Company’s results of operations, financial position or liquidity,” there is a risk that losses realized on derivative settlements during periods of weakening yen may not be recouped through realization of the corresponding holding currency gains on the hedged U.S. dollar-denominated investments if these investments are not ultimately converted to yen.

The Company has taken steps to refine the strategy to mitigate currency exposure of Aflac Japan from U.S. dollar-denominated investments while balancing the consideration of the economic equity surplus in Aflac Japan. This refinement in strategy resulted in an increased amount of the unhedged U.S. dollar-denominated investments held in Aflac Japan while at the same time mitigating hedge cost or amortized cost, whose carrying value is hedged againstincreases. Generally, Aflac Japan’s exposure to the currency risk using foreign currency forwards and in-the-money foreign currency options and $13.0 billionincreases when its portfolio of unhedged U.S. dollar-denominated investments at amortized cost, that are not hedged as of December 31, 2017. Aflac Japan also owns Reverse Dual Currency bonds (RDCs) of $7.1 billion, which provide for coupon payments in fixed U.S. dollar amounts and principal payments in fixed yen amounts. RDCs exposeincreases. As the Company to changes in foreign exchange rates. The change in fair value of the yen-denominated securitiesU.S. dollar-denominated investment portfolio in Aflac Japan fluctuates and the Company’s business model evolves, the Company periodically reevaluates this size of the unhedged portfolio and may accordingly adjust up or down its currency hedging targets. See additional discussion in the Risk Factors section titled "The Company is accounted for as a component of unrealized gains or losses on available-for-sale securities in accumulated other comprehensive income, while theexposed to foreign currency effect onfluctuations in the yen/dollar coupons is realized in earnings.exchange rate."



The Parent Company
72





The Company is exposed to currency risk as an economic event when yen funds are actually converted into U.S. dollars. This occurs when the Company repatriates yen-denominated funds are paid as dividends and management fees from Aflac Japan to Aflac U.Sthe Parent Company and with quarterly settlements of its reinsurance retrocession transactions. The exchange rates prevailing at the time of profit repatriationyen payments will differ from the exchange rates prevailing at the time the yen profits were earned. A portion of the yen repatriationdividend and management fee payments may be used to service Aflac Incorporated's yen-denominated notes payable with the remainder converted into U.S. dollars. In order to economically hedge foreign exchange risk for a portion of the profit repatriation received in yen from Aflac Japan, the Company had foreign exchange forwards and options as part of a hedging strategy on 90.9 billion yen received in 2017. As of December 31, 2017, the Company had foreign exchange forwards and options to economically hedge foreign exchange risk on 49.5 billion yen of future profit repatriation from Aflac Japan.


In addition to profit repatriationyen payments and the reinsurance retrocessions, certain investment activities for Aflac Japan expose the Company to economic currency risk when yen are converted into U.S. dollars. As noted above, the Company invests a portion of its yen cash flows in U.S. dollar-denominated assets. This requires that the Company convert the yen cash flows to U.S. dollars before investing. As previously discussed, for certain of its U.S. dollar-denominated securities, the Company enters into foreign currency forward and option contracts to hedge the currency risk on the fair value of hedged investments. In 2018, the Parent Company entered into forward contracts to accomplish a dual objective of hedging foreign currency rate risk to dividend payments by Aflac Japan, and reducing enterprise-wide hedge costs. If the markets experience a significant strengthening of yen, this could cause cash strain at the Parent Company as a result of cash collateral and potentially cash settlement requirements. Based on the timing and severity of exchange rate fluctuations combined with the level of outstanding activity in this program, the cash strain at the Parent Company could be significant.
Aside from the activities discussed above, the Company generally does not convert yen into U.S. dollars; however, it does translate financial statement amounts from yen into U.S. dollars for financial reporting purposes. Therefore, reported amounts are affected by foreign currency fluctuations. The Company reports unrealized foreign currency translation gains and losses in accumulated other comprehensive income.AOCI. In periods when the yen weakens against the dollar, translating yen into dollars causes fewer dollars to be reported. When the yen strengthens, translating yen into U.S. dollars causes more U.S. dollars to be reported. The weakening of the yen relative to the U.S. dollar will generally adversely affect the value of the Company's yen-denominated investments in U.S. dollar terms. The Company also considers the stressed economic equity surplus in Aflac Japan and related exposure to foreign currency. The Company manages this currency risk by investing a portion of Aflac Japan's investment portfolio in U.S. dollar-denominated securities and by the Parent Company's issuance of yen-denominated debt (for additional information, see the discussion under the Investments subsection within Item 1, Business).debt. As a result, the effect of currency fluctuations on the Company's net assets is reduced.

As discussed above in the Investment subsection of Item 1, Business, the Company engages in hedging activities to mitigate certain currency risks from holding U.S. dollar-denominated investments in Aflac Japan. However, this hedging program in turn poses a countervailing long-term risk of loss on hedging currency derivatives under the long-term scenario of weakening yen, and related derivative rollover risk that could amplify hedge cost in unfavorable market conditions and significantly increase liquidity requirements to support negative derivative settlements. Additionally, as discussed in detail in the Risk Factors section titled “Lack of availability of acceptable yen-denominated investments could adversely affect the Company’s results of operations, financial position or liquidity,” there is a risk that losses realized on derivative settlements during periods of weakening yen may not be recouped through realization of the corresponding holding currency gains on the hedged U.S. dollar-denominated investments if these investments are not ultimately converted to yen.

As noted above, in late 2017, the Company took steps to refine the strategy to mitigate currency exposure of Aflac Japan from U.S. dollar-denominated investments while balancing the consideration of the stressed economic surplus in Aflac Japan. This refinement in strategy resulted in an increased amount of the unhedged U.S. dollar-denominated investments held in Aflac Japan while at the same time mitigating hedge cost increases. Generally, Aflac Japan’s exposure to the currency risk increases when its portfolio of unhedged U.S. dollar-denominated investments increases. This increases the volatility of the SMR and FSA earnings and may result in an adverse impact on these regulatory measures when yen appreciates relatively to U.S. dollar. This in turn may reduce Aflac Japan’s repatriation or dividend capacity, as well as increase the level of capital needed to support increased SMR volatility. The adverse impact on the regulatory measures could be amplified by regulatory accounting rules requiring impairment loss recognition on prolonged significant declines in U.S. dollar relative to yen. Furthermore, under the scenario where unhedged U.S. dollar-denominated investments are needed to pay Aflac Japan’s yen-denominated obligations, they would have to be converted to yen, which could force realization of the then potential currency losses. As the value of the U.S. dollar-denominated investment portfolio in Aflac Japan fluctuates and the Company’s business model evolves, the Company will periodically reevaluate this size of the unhedged portfolio and may accordingly adjust up or down its currency hedging targets.
The following table demonstrates the effect of foreign currency fluctuations by presenting the dollar values of the Company's yen-denominated assets and liabilities, and its consolidated yen-denominated net asset exposure at selected exchange rates as of December 31.

(3) Does not include U.S. dollar-denominated bonds that have corresponding cross-currency swaps in consolidated VIEs


The Company is required to consolidate certain VIEs. Some of the consolidated VIEs in Aflac Japan's portfolio use foreign currency swaps to convert foreign denominated cash flows to yen, the functional currency of Aflac Japan, in order to minimize cash flow fluctuations. Foreign currency swaps exchange an initial principal amount in two currencies, agreeing to re-exchange the currencies at a future date, at an agreed upon exchange rate. There may also be periodic exchanges of payments at specified intervals based on the agreed upon rates and notional amounts. Prior to consolidation, the Company's beneficial interest in these VIEs was a yen-denominated available-for-sale fixed maturity security. Upon consolidation, the original yen-denominated investment was derecognized and the underlying fixed-maturity or perpetualfixed maturity securities and cross-currency swaps were recognized. The combination of a U.S. dollar-denominated investment and cross-currency swap economically creates a yen-denominated investment and has no impact on the Company's net investment hedge position.


Similarly, the combination of the U.S. corporate bonds and the foreign currency forwards and options that the Company has entered into, as discussed in the Aflac Japan Investment subsection of MD&A, economically creates a yen-denominated investment that qualifies for inclusion as a component of the Company's investment in Aflac Japan for net investment hedge purposes.

Item 7A. Quantitative and Qualitative Disclosures About Market Risk

Interest Rate Risk


The Company's primary interest rate exposure is to the impact of changes in interest rates on the fair value of its investments in debt and perpetual securities. The Company monitors its investment portfolio on a quarterly basis utilizing a full valuation methodology, measuring price volatility, and sensitivity of the fair values of its investments to interest rate changes on the debt and perpetual securities the Company owns. For example, if the current duration of a debt security or perpetual security is 10 years, then the fair value of that security will increase by approximately 10% if market interest rates decrease by 100 basis points, assuming all other factors remain constant. Likewise, the fair value of the debt security or perpetual security will decrease by approximately 10% if market interest rates increase by 100 basis points, assuming all other factors remain constant.


The estimated effect of potential increases in interest rates on the fair values of debt and perpetual securities the Company owns; derivatives, excluding credit default swaps, and notes payable as of December 31 follows:

There are various factors that affect the fair value of the Company's investment in debt and perpetual securities. Included in those factors are changes in the prevailing interest rate environment, which directly affect the balance of unrealized gains or losses for a given period in relation to a prior period. Decreases in market yields generally improve the fair value of debt and perpetual securities, while increases in market yields generally have a negative impact on the fair value of the Company's debt and perpetual securities. However, the Company does not expect to realize a majority of any unrealized gains or losses because it generally has the intent and ability to hold such securities until a recovery of value, which may be maturity.losses. For additional information on unrealized losses on debt and perpetual securities, see Note 3 of the Notes to the Consolidated Financial Statements.

Aflac Japan investment yields above includes U.S. dollar–denominated investment yields prior to factoring in amortized hedge costs. The Company continues to monitor the spread between its new money yield and the required interest assumption for newly issued products in both the United StatesU.S. and Japan and will re-evaluate those assumptions as necessary. Over the next two years, the Company has yen-denominated securities that will mature with yields in excess of Aflac Japan's current net investment yield of 1.88%. These securities total $1.7 billion at amortized cost and have a weighted average yield of 3.57%. Currently, when debt and perpetual securitiesinvestments the Company owns mature, the proceeds may be reinvested at a yield below that of the interest required for the accretion of policy benefit liabilities on policies issued in earlier years. Overall, adequate profit margins exist in Aflac Japan's aggregate block of business because of changes in the mix of business and favorable experience from mortality, morbidity and expenses.


The Company holds investments and has issued debt with interest rates based on LIBOR, and also holds derivatives that reference LIBOR. Regulatory and industry initiatives to eliminate LIBOR as an interest rate benchmark may create uncertainty in the valuation of LIBOR-based loans, as well as for other LIBOR-based derivatives and assets. This may adversely impact both pricing and liquidity in such instruments. The Company is preparing for the expected discontinuation of LIBOR by identifying, assessing and monitoring risks associated with LIBOR transition. Preparation includes taking steps to update operational processes (including to support alternative reference rates) and models, as well as evaluating legacy contracts for any changes that may be required, including the determination of applicable fallbacks.

Periodically, the Company may enter into derivative transactions to hedge interest rate risk, depending on general economic conditions.

For furtheradditional information on interest rate derivatives, see the Hedging Activities subsection of MD&A and Note 4 of the accompanying Notes to the Consolidated Financial Statements.


Credit Risk


A significant portion of the Company's investment portfolio consists of debt securities or perpetual securities and loans that expose it to the credit risk of the underlying issuer or borrower. The Company carefully evaluates this risk on every new investment and closely monitors the credit risk of its existing investment portfolio. The Company incorporates the needs of its products and liabilities, the overall requirements of the business, and other factors in addition to its underwriting of the credit risk for each investment in the portfolio.


Evaluating the underlying risks in the Company's credit portfolio involves a multitude of factors including but not limited to its assessment of the issuer's or borrower's business activities, assets, products, market position, financial condition, and future prospects. The Company incorporates the assessment of the NRSROs in assigning credit ratings

76




and incorporates the rating methodologies of its specialist external managers in assigning loan ratings to portfolio holdings. The Company performs extensive internal assessments of the credit risks for all its portfolio holdings and potential new investments, which includes using analyses provided by the Company's specialist external managers. For assets managed by external asset managers, the Company provides investment and credit risk parameters that must be used when making investment decisions and requirerequires ongoing monitoring and reporting from the asset managers on significant changes in credit risks within the portfolio.

As previously disclosed, the Company owns long-dated debt instruments in support of its long-dated policyholder obligations. Some of the Company's largest global investment holdings are positions that were purchased many years ago and increased in size due to merger and consolidation activity among the issuing entities. In addition, many of the Company's largest holdings are yen-denominated, therefore strengthening of the yen can increase its position in dollars, and weakening of the yen can decrease its position in dollars. The Company's global investment guidelines establish concentration limits for its investment portfolios.

The primary factor considered when determining the domicile of investment exposure is the legal country risk location of the issuer. However, other factors such as the location of the parent guarantor, the location of the company's headquarters or major business operations (including location of major assets), location of primary market (including location of revenue generation) and specific country risk publicly recognized by rating agencies can influence the assignment of the country (or geographic) risk location. When the issuer is a special financing vehicle or a branch or subsidiary of a global company, then the Company considers any guarantees and/or legal, regulatory and corporate relationships of the issuer relative to its ultimate parent in determining the proper assignment of country risk.

Item 7A. Quantitative and Qualitative Disclosures About Market Risk


Derivative Counterparties
The Company is a direct counterparty to the foreign currency swaps that it has entered into in connection with certainmajority of its senior notesderivative instruments and subordinated debentures; foreign currency forwards; foreign currency options; and interest rate swaptions, therefore the Company is exposed to credit risk in the event of nonperformance by the counterparties in those contracts. For the foreign currency and credit default swaps associated with the Company's VIE investments for which it is the primary beneficiary, the Company bears the risk of foreign exchange and/or credit loss due to counterparty default even though it is not a direct counterparty to those contracts. The risk of counterparty default for the Company's VIE and senior note and subordinated debenture swaps, foreign currency swaps, certain foreign currency forwards, foreign currency options and interest rate swaptions is mitigated by collateral posting requirements that counterparties to those transactions must meet. If collateral posting agreements are not in place, the counterparty risk associated with foreign currency forwards and foreign currency options is the risk that at expiry of the contract, the counterparty is unable to deliver the agreed upon amount of yen at the agreed upon price or delivery date, thus exposing the Company to additional unhedged exposure to U.S. dollars in the Aflac Japan investment portfolio. See Note 4 of the accompanying Notes to the Consolidated Financial Statements for more information.


Equity Risk


Market prices for equity securities are subject to fluctuation and consequently the amount realized in the subsequent sale of an investment may significantly differ from the reported market value. Fluctuation in the market price of a security may result from the relative price of alternative investments and general market conditions. If equity prices experienced a hypothetical broad-based decline of 10%, the fair value of the Company's equity investments would decline by approximately $102$80 million.

Report of Independent Registered Public Accounting Firm
To the Shareholders and Board of Directors
Aflac Incorporated:


Opinion on Internal Control Over Financial Reporting
We have audited Aflac Incorporated and subsidiaries’ (the “Company”)Company) internal control over financial reporting as of December 31, 2017,2019, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission.Commission (COSO) in 2013. In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2017,2019, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission.Commission (COSO) in 2013.
We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (“PCAOB”)(PCAOB), the consolidated balance sheets of the Company as of December 31, 20172019 and 2016,2018, the related consolidated statements of earnings, comprehensive income (loss), shareholders’ equity, and cash flows for each of the years in the three-year period ended December 31, 2017,2019, and the related notes and financial statement schedules II, III, and IV (collectively, the “consolidatedconsolidated financial statements”)statements), and our report dated February 22, 201821, 2020 expressed an unqualified opinion on those consolidated financial statements.
Basis for Opinion
The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management's Annual Report on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audit also included performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.
Definition and Limitations of Internal Control Over Financial Reporting
A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.
Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Report of Independent Registered Public Accounting Firm
To the Shareholders and Board of Directors
Aflac Incorporated:


Opinion on the ConsolidatedFinancial Statements
We have audited the accompanying consolidated balance sheets of Aflac Incorporated and subsidiaries (the “Company”)Company) as of December 31, 20172019 and 2016,2018, the related consolidated statements of earnings, comprehensive income (loss), shareholders’ equity, and cash flows for each of the years in the three‑year period ended December 31, 2017,2019, and the related notes and financial statement schedules II, III, and IV (collectively, the “consolidatedconsolidated financial statements”)statements). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 20172019 and 2016,2018, and the results of its operations and its cash flows for each of the years in the three‑year period ended December 31, 2017,2019, in conformity with U.S. generally accepted accounting principles.
We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (“PCAOB”)(PCAOB), the Company’s internal control over financial reporting as of December 31, 2017,2019, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) in 2013, and our report dated February 22, 201821, 2020 expressed an unqualified opinion on the effectiveness of the Company’s internal control over financial reporting.
Basis for Opinion
These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these consolidated financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. We believe that our audits provide a reasonable basis for our opinion.

Item 8. Financial Statements and Supplementary Data


Critical Audit Matters
The critical audit matters communicated below are matters arising from the current period audit of the consolidated financial statements that were communicated or required to be communicated to the audit committee and that: (1) relate to accounts or disclosures that are material to the consolidated financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matters below, providing separate opinions on the critical audit matters or on the accounts or disclosures to which they relate.
Assessment of the measurement of fair value of certain investments and derivatives
As discussed in Note 5 to the consolidated financial statements, the Company has certain privately issued securities and derivative instruments associated with variable interest entities (VIEs) that require significant judgment in the estimation of fair value. The fair value of privately issued securities are estimated using valuation models developed by a third party pricing vendor and require judgment to determine the inputs and assumptions used in the valuation models, such as credit default swap (CDS) spreads and the selection of comparable securities, when appropriate. The fair value of the Company’s derivatives associated with VIEs are also estimated using valuation models developed by a third party pricing vendor. Given the long duration of derivatives associated with VIEs, the estimate of the fair value requires judgment to extrapolate short-term observable data into long-term inputs for use in the valuation models. As of December 31, 2019, the value of privately issued securities are included within the financial statement captions of fixed maturity securities available for sale, at fair value; fixed maturity securities available for sale - consolidated variable interest entities, at fair value; and, fixed maturity securities held to maturity, at amortized cost, which totaled $86,950 million, $4,312 million, and $30,085 million, respectively. As of December 31, 2019, the fair value of derivatives associated with VIEs are included within the financial statement captions of other assets and other liabilities, which totaled $2,368 million and $3,440 million, respectively.
We identified the assessment of the measurement of fair value of certain privately issued securities and derivative instruments associated with VIEs as a critical audit matter. Due to the complexity of the valuation models, specialized valuation skills and knowledge and subjective auditor judgment were needed to evaluate the valuation models and the inputs and assumptions used in the models to estimate fair value.
The primary procedures we performed to address this critical audit matter included the following. We tested certain internal controls, with the involvement of valuation professionals when appropriate, over the Company’s process to estimate the fair value of such securities and derivative instruments, including controls over the Company’s evaluation of the inputs, assumptions and estimates of fair value obtained from its third party pricing vendor. We involved valuation professionals with specialized skills and knowledge to assist in assessing the estimated fair values of such securities and derivative instruments, which included:
Evaluating the inputs and assumptions used in the models to estimate the fair value of the privately issued securities, including an assessment of the determination of comparable securities and/or CDS spreads used by the third party pricing vendor for a selection of privately issued securities.
Assessing the internal models used by the Company to evaluate the fair values for privately issued securities and derivatives associated with VIEs obtained from the third party pricing vendor. We observed that differences, if any, in fair value between the Company and the third party pricing vendor above pre-established tolerances were investigated by the Company.
Developing an independent estimate of the fair value for a selection of privately issued securities and derivative instruments associated with VIEs and comparing our independent estimate to the fair value measurement recorded by the Company.

Item 8. Financial Statements and Supplementary Data


Assessment of the estimate of unpaid policy claims
As discussed in Note 1 to the consolidated financial statements, unpaid policy claims are estimates computed primarily on an undiscounted basis using statistical analyses of historical claims experience adjusted for current trends and changed conditions. The estimates are evaluated by the Company and, as new claim experience emerges, the estimates are adjusted as necessary. As of December 31, 2019, the Company recorded a liability for unpaid policy claims of $4,659 million.
We identified the assessment of the estimate of unpaid policy claims as a critical audit matter. Specialized actuarial skills and knowledge and subjective auditor judgment were needed to evaluate the actuarial methodologies and assumptions used to estimate the unpaid policy claims liability and determine that the Company’s methodologies are consistent with generally accepted actuarial methodologies.
The primary procedures we performed to address this critical audit matter included the following. We tested, with the involvement of actuarial professionals when appropriate, certain internal controls over the Company’s process to estimate the unpaid policy claims liability, including controls related to the evaluation of the actuarial methodologies and assumptions used in the calculation of the unpaid policy claims liability. We involved actuarial professionals with specialized skills and knowledge to assist in assessing the unpaid policy claims liability, which included:
Assessing the actuarial methodologies and assumptions utilized by the Company by comparing them to generally accepted actuarial methodologies and historical results.
Evaluating the Company’s estimate of the unpaid policy claims liability by comparing to historical results and our expectations of changes in the estimate.
Developing an independent range for the estimate of unpaid policy claims for certain products to evaluate the Company’s recorded liability and assessing any movement of the recorded liability within our range.
Evaluating the Company’s historical ability to estimate unpaid policy claims by comparing the unpaid policy claims liability for certain products recorded by the Company at various historical periods to an independent range developed using claims paid through December 31, 2019.

Aflac Incorporated and Subsidiaries
Notes to the Consolidated Financial Statements
1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
Description of Business
Aflac Incorporated (the Parent Company) and its subsidiaries (collectively, the Company) primarily sell supplemental health and life insurance in the United States (U.S.) and Japan. The Company's insurance business is marketed and administered through American Family Life Assurance Company of Columbus (Aflac), which operates in the United States (Aflac U.S.) and, effective April 1, 2018, through Aflac Life Insurance Japan Ltd. (ALIJ) in Japan. Prior to April 1, 2018, the Company's insurance business was marketed in Japan as a branch inof Aflac. The Company’s operations consist of two reportable business segments: Aflac U.S., which includes Aflac, and Aflac Japan, (Aflac Japan).which includes ALIJ. American Family Life Assurance Company of New York (Aflac New York) is a wholly owned subsidiary of Aflac. Most of Aflac's policies are individually underwritten and marketed through independent agents. Additionally, Aflac U.S. markets and administers group products through Continental American Insurance Company (CAIC), branded as Aflac Group Insurance. The Company's insurance operations in the United StatesU.S. and its branch in Japan service the two markets for the Company's insurance business. Aflac Japan's revenues, including realized gains and losses on its investment portfolio, accounted for 70%69% of the Company's total revenues in 2017,2019, compared with 71% in 2016 and 70% in 2015.both 2018 and 2017. The percentage of the Company's total assets attributable to Aflac Japan was 83% at December 31, 20172019, compared with 84% at December 31, 2018.

In November 2019, the Company acquired Argus Holdings, LLC and 2016.its subsidiary Argus Dental & Vision, Inc. (Argus), a benefits management organization and national network dental and vision company, which provides a platform for Aflac Dental and Vision. The Company paid $75 million at closing and made an additional commitment of up to $21 million in contingent consideration payable over three years based on the achievement by Argus of certain performance targets. Argus is an addition to the Aflac U.S. segment.


Basis of Presentation
The Company prepares its financial statements in accordance with U.S. generally accepted accounting principles (GAAP)(U.S. GAAP). These principles are established primarily by the Financial Accounting Standards Board (FASB). In these Notes to the Consolidated Financial Statements, references to U.S. GAAP issued by the FASB are derived from the FASB Accounting Standards CodificationTM (ASC). The preparation of financial statements in conformity with U.S. GAAP requires the Company to make estimates based on currently available information when recording transactions resulting from business operations. The most significant items on the Company's balance sheet that involve a greater degree of accounting estimates and actuarial determinations subject to changes in the future are the valuation of investments and derivatives, deferred policy acquisition costs (DAC), liabilities for future policy benefits and unpaid policy claims, and income taxes. These accounting estimates and actuarial determinations are sensitive to market conditions, investment yields, mortality, morbidity, commission and other acquisition expenses, and terminations by policyholders. As additional information becomes available, or actual amounts are determinable, the recorded estimates will be revised and reflected in operating results. Although some variability is inherent in these estimates, the Company believes the amounts provided are adequate.


The consolidated financial statements include the accounts of the Parent Company, its subsidiaries, and those entities required to be consolidated under applicable accounting standards. All material intercompany accounts and transactions have been eliminated.


Significant Accounting Policies


Translation of Foreign Currencies:Currency Translation: The functional currency of Aflac Japan's insurance operationsJapan is the Japanese yen. The Company translates its yen-denominated financial statement accounts into U.S. dollars as follows. Assets and liabilities are translated at end-of-period exchange rates. Realized gains and losses on security transactions are translated at the exchange rate on the trade date of each transaction. Other revenues, expenses, and cash flows are translated using average exchange rates for the period. The resulting currency translation adjustments are reported in accumulated other comprehensive income.

derivatives are recorded as unrealized foreign currency translation gains (losses) in other comprehensive income and are included in accumulated other comprehensive income.


Insurance Revenue and Expense Recognition: The Substantially all of the supplemental health and life insurance policies the Company issues are classified as long-duration contracts. The contract provisions generally cannot be changed or canceled during

88



the contract period; however, the Company may adjust premiums for supplemental health policies issued in the United StatesU.S. within prescribed guidelines and with the approval of state insurance regulatory authorities.


Insurance premiums for most of the Company's health and life policies, including cancer, accident, hospital, critical illness, dental, vision, term life, whole life, long-term care and disability, are recognized as revenue over the premium-paying periods of the contracts when due from policyholders. When revenues are reported, the related amounts of benefits and expenses are charged against such revenues, so that profits are recognized in proportion to premium revenues during the period the policies are expected to remain in force. This association is accomplished by means of annual additions to the liability for future policy benefits and the deferral and subsequent amortization of policy acquisition costs.


Premiums from the Company's products with limited-pay features, including term life, whole life, WAYS, and child endowment, are collected over a significantly shorter period than the period over which benefits are provided. Premiums for these products are recognized as revenue over the premium-paying periods of the contracts when due from policyholders. Any gross premium in excess of the net premium is deferred and recorded in earnings, such that profits are recognized in a constant relationship with insurance in force. Benefits are recorded as an expense when they are incurred. A liability for future policy benefits is recorded when premiums are recognized using the net premium method.


At the policyholder's option, customers can also pay discounted advanced premiums for certain of the Company's products. Advanced premiums are deferred and recognized when due from policyholders over the regularly scheduled premium payment period.


The calculation of DAC and the liability for future policy benefits requires the use of estimates based on sound actuarial valuation techniques. For new policy issues, the Company reviews its actuarial assumptions and deferrable acquisition costs each year and revises them when necessary to more closely reflect recent experience and studies of actual acquisition costs. For policies in force, the Company evaluates DAC by major product groupings to determine that they are recoverable from future revenues, and any amounts determined not to be recoverable are charged against net earnings. The Company has not had any material charges to earnings for DAC that was determined not to be recoverable in any of the years presented in this Form 10-K.


Advertising expense is reported as incurred in insurance expenses in the consolidated statements of earnings.


Cash and Cash Equivalents: Cash and cash equivalents include cash on hand, money market instruments, and other debt instruments with a maturity of 90 days or less when purchased.


Investments: The Company's debt securities consist of fixed-maturityfixed maturity securities, which are classified as either held to maturity or available for sale. Securities classified as held to maturity are securities that the Company has the ability and intent to hold to maturity or redemption and are carried at amortized cost. All other fixed-maturityfixed maturity debt securities, perpetual securities, and equity securities are classified as available for sale and are carried at fair value. If the fair value is higher than the amortized cost for debt and perpetual securities, or the purchase cost for equity securities, the excess is an unrealized gain, and if lower than cost, the difference is an unrealized loss. The net unrealized gains and losses on securities available for sale, less related deferred income taxes, are recorded through other comprehensive income and included in accumulated other comprehensive income.


Amortized cost of debt and perpetual securities is based on the Company's purchase price adjusted for accrual of discount, or amortization of premium, and recognition of impairment charges, if any. The amortized cost of debt and perpetual securities the Company purchases at a discount or premium will equal the face or par value at maturity or the call date, if applicable. Interest is reported as income when earned and is adjusted for amortization of any premium or discount.


The Company has investments in marketable equity securities which are carried at fair value. Changes in the fair value of equity securities are recorded in earnings as a component of realized investment gains and losses.

The Company has investments in variable interest entities (VIEs). Criteria for evaluating VIEs for consolidation focuses on identifying which enterprise has the power to direct the activities of a variable interest entity that most significantly impact the entity's economic performance and (1) the obligation to absorb losses of the entity or (2) the right to receive benefits from the entity. The Company is the primary beneficiary of certain VIEs, and therefore consolidates these entities in its financial statements. While the consolidated VIEs generally operate within a defined set of documents,contractual terms, there are certain powers

88


Item 8. Financial Statements and Supplementary Data


that are retained by the Company that are considered significant in the conclusion that the Company is the primary beneficiary. These powers vary by structure but generally include the initial selection of the underlying collateral or, for collateralized debt obligations (CDOs), the reference credits to include in the structure;collateral; the ability to obtain the underlying collateral in the event of default; and, the ability to appoint or dismiss key parties in the structure. In particular, the Company's powers surrounding the underlying collateral were considered to be the most

89



significant powers sincebecause those most significantly impact the economics of the VIE. The Company has no obligation to provide any continuing financial support to any of the entities in which it is the primary beneficiary. The Company's maximum loss is limited to its original investment. Neither the Company nor any of its creditors hashave the ability to obtain the underlying collateral, nor does the Company have control over the instruments held in the VIEs, unless there is an event of default. For those entities where the Company is the primary beneficiary, the consolidated entity's assets consolidated are segregated on the balance sheet by the caption "consolidated variable interest entities," and consist of fixed-maturity securities, perpetualfixed maturity securities, equity securities, loan receivables, limited partnerships and derivative instruments.


For the mortgage- and asset-backed securities held in the Company's fixed maturitiesmaturity portfolio, the Company recognizes income using a constant effective yield, which is based on anticipated prepayments and the estimated economic life of the securities. When estimates of prepayments change, the effective yield is recalculated to reflect actual payments to date and anticipated future payments. The net investment in mortgage- and asset-backed securities is adjusted to the amount that would have existed had the new effective yield been applied at the time of acquisition. This adjustment is reflected in net investment income.


The Company uses the specific identification method to determine the gain or loss from securities transactions and report the realized gain or loss in the consolidated statements of earnings. Securities transactions are accounted for based on values as of the trade date of the transaction.


An investment in a fixed maturity perpetual security, or equity security is impaired if the fair value falls below book value.amortized cost. The Company regularly reviews its entire investmentfixed maturity security investments portfolio for declines in fair value. The Company's fixed maturities and investment-grade perpetual securitiesmaturity security investments are evaluated for other-than-temporary impairment using its debt impairment model. The Company's debt impairment model focuses on the ultimate collection of the cash flows from its investments and whether the Company has the intent to sell or if it is more likely than not the Company would be required to sell the security prior to recovery of its amortized cost. The determination of the amount of impairments under this model is based upon the Company's periodic evaluation and assessment of known and inherent risks associated with the respective securities. Such evaluations and assessments are revised as conditions change and new information becomes available.
When determining the Company's intention to sell a security prior to recovery of its fair value to amortized cost, the Company evaluates facts and circumstances such as, but not limited to, future cash flow needs, decisions to reposition its security portfolio, and risk profile of individual investment holdings. The Company performs ongoing analyses of its liquidity needs, which includes cash flow testing of its policy liabilities, debt maturities, projected dividend payments, and other cash flow and liquidity needs. The Company's cash flow testing includes extensive duration analysis of its investment portfolio and policy liabilities. Based on the Company's analyses, the Company has concluded that it has sufficient excess cash flows to meet its liquidity needs without selling any of its investments prior to their maturity.


The determination of whether an impairment in value of the Company's fixed maturity securities is other than temporary is based largely on the Company's evaluation of the issuer's creditworthiness. The Company must apply considerable judgment in determining the likelihood of its fixed maturity securities recovering in value. Factors that may influence this include the overall level of interest rates, credit spreads, the credit quality of the underlying issuer, and other factors. This process requires consideration of risks which can be controlled to a certain extent, such as credit risk, and risks which cannot be controlled, such as interest rate risk and foreign currency risk.


If, after monitoring and analyses, management believes that fair value will not recover to amortized cost, prior to the disposal of the security, the Company recognizes an other-than-temporary impairment of the security. Once a security is considered to be other-than-temporarily impaired, the impairment loss is separated into two separate components: the portion of the impairment related to credit and the portion of the impairment related to factors other than credit. The Company recognizes a charge to earnings for the credit-related portion of other-than-temporary impairments. Impairments related to factors other than credit are charged to earnings in the event the Company intends to sell the security prior to the recovery of its amortized cost or if it is more likely than not that the Company would be required to dispose of the security prior to recovery of its amortized cost; otherwise, non-credit-related other-than-temporary impairments are charged to other comprehensive income.

The Company's investments in perpetual securities that are rated below investment grade and equity securities are evaluated for other-than-temporary impairment under the Company's equity impairment model. The Company's equity impairment model focuses on the severity of a security's decline in fair value coupled with the length of time the fair value of the security has been below amortized cost and the financial condition and near-term prospects of the issuer. For equity securities that have declines in value that are deemed to be temporary, the Company makes an assertion as to its ability and intent to retain the security until recovery. Once identified, these equity securities are restricted from trading unless

90



authorized based upon significant events that could not have been foreseen at the time the Company asserted its ability and intent to retain the security until recovery.

If management believes that the equity security will not recover prior to the disposal of the security, the Company recognizes an other-than-temporary impairment of the security. Once an equity security is considered to be other-than-temporarily impaired, its fair value on that date becomes the new cost basis and the impairment loss is recognized in earnings.


The Company lends fixed-maturityfixed maturity and public equity securities to financial institutions in short-term security lendingsecurity-lending transactions. These securities continue to be carried as investment assets on the Company's balance sheet during the terms of the loans and are not reported as sales. The Company receives cash or other securities as collateral for such loans. For loans involving unrestricted cash or securities as collateral, the collateral is reported as an asset with a corresponding liability for the return of the collateral. For loans where the Company receives as collateral securities that the Company is not permitted to sell or repledge, the collateral is not reported as an asset.

Commercial mortgage and other loans include transitional real estate loans (TREs), commercial mortgage loans (CMLs), and middle market loans (MMLs), policy loans, limited partnerships, and other short-term. The Company's investments with maturities of one year or less, but greater than 90 days, at the time of purchase. The Company invests in TREs, CMLs, and MMLs that are accounted for as loan receivables and are recorded at amortized cost on the acquisition date. Since theThe Company has the intent and ability to hold these loan receivables for the foreseeable future or until they mature and therefore, they are considered held for investment and are carried at adjusted amortized cost in the commercial mortgage and other investmentsloans line onin its consolidated balance sheets. The adjusted amortized cost of the loan receivables reflects allowances for expected incurred losses estimated based on past events and current economic conditions as of each reporting date.

Other investments include policy loans, limited partnerships, and short-term investments with maturities at the time of purchase of one year or less, but greater than 90 days. Limited partnership investmentspartnerships are accounted for using the equity method of accounting. Under the equity method of accounting, the Company reports its portion of partnership earnings as a component of net investment income in its consolidated statements of earnings. The underlying investments held by the Company’s limited partnerships primarily consist of private equity. Other short-termequity and real estate. Short-term investments are stated at amortized cost, which approximates estimated fair value.


Derivatives and Hedging: Freestanding derivative instruments are reported in the consolidated balance sheet at fair value and are reported in other assets and other liabilities, with changes in value reported in earnings and/or other comprehensive income. These freestanding derivatives are interest rate swaps, foreign currency swaps, credit default swaps (CDSs), foreign currency forwards, foreign currency options, foreign currency swaps, interest rate swaps, interest rate swaptions, and, in prior year periods, options on interest ratecredit default swaps (or interest rate swaptions)(CDSs). Interest rate and foreign currency swaps are used within VIEs to hedge the risk arising from interest rate and currency exchange risk, while the CDSs are used to increase the yield and improve the diversification of the portfolio. Foreign currency forwards and options are used in hedging foreign exchange risk on U.S. dollar-denominated investments in Aflac Japan's portfolio. Foreign currency forwards and options are used to hedge certain portions of forecasted cash flows denominated in yen. Interest rate swaps are used to hedge the variability of interest cash flows associated with the Company's variable interest rate notes. Cross-currency interest rate swaps, also referred to as foreign currency swaps, are used to economically convert certain U.S. dollar-denominated note obligations into yen-denominated principal and interest obligations. Interest rate swaptions have been used from time to time to hedge interest rate risk for certain U.S. dollar-denominated available-for-sale securities. The Company does not use derivatives for trading purposes, nor does the Company engage in leveraged derivative transactions.


From time to time, the Company purchases certain investments that contain an embedded derivative. The Company assesses whether this embedded derivative is clearly and closely related to the asset that serves as its host contract. If the Company deems that the embedded derivative's terms are not clearly and closely related to the host contract, and a separate instrument with the same terms would qualify as a derivative instrument, the derivative is separated from that contract, held at fair value, and reported with the host instrument in the consolidated balance sheet, with changes in fair value reported in earnings. If the Company has elected the fair value option, the embedded derivative is not bifurcated, and the entire investment is held at fair value with changes in fair value reported in earnings.
See Note 5 for a discussion on how the Company determines the fair value of its derivatives. Accruals on derivatives are typically recorded in accrued investment incomeother assets or within other liabilities in the consolidated balance sheets.


To qualify for hedge accounting treatment, a derivative must be highly effective in mitigating the designated risk ofattributable to the hedged item. At the inception of hedging relationships for which the Company elects to designate for hedge accounting treatment, the Company formally documents all relationships between hedging instruments and hedged items, as well as its risk-management objectives and strategies for undertaking eachthe respective hedging relationship, and the methodology that will be used to assess the effectiveness of the hedge transaction.relationship at and subsequent to hedge inception. The Company documents the designation of each hedge as either (i) a hedge of the variability of cash flows to be received or paid related to a recognized asset or liability or the hedge of a forecasted transaction ("cash flow hedge"); (ii) a hedge of the estimated fair value of a recognized asset or liability ("fair value hedge"); or (iii) a hedge of a net investment in a foreign operation. The

91



documentation process includes linking derivatives and non-derivative financial instruments that are designated as hedges to specific assets or groups of assets or liabilities onin the statement of financial position or to specific forecasted transactions and defining the effectiveness and ineffectiveness testing methods to be used. At the hedge'shedge inception and on an ongoing quarterly basis, the Company also formally assesses whether the derivatives and non-derivative financial instruments used in hedging activities have been, and are expected to continue to be, highly effective in offsetting their designated risk. Hedge effectiveness is assessed using qualitative and quantitative methods. The assessment of hedge effectiveness determines the accounting treatment of noncash changes in fair value.
For assessing hedge effectiveness, of cash flow hedges, qualitative methods may include the comparison of critical terms of the derivative to the hedged item, and quantitative methods may include regression, dollar offset, or other statistical analysis of changes in fair value or cash flows associated with the hedge relationship. Hedge ineffectiveness of the hedge relationships on the Company's VIE cash flow hedges is measured each reporting period using the “Hypothetical Derivative Method.”
For derivative instruments that are designated and qualify as cash flow hedges, the effective portion of the gain or loss on the derivative is reported as a component of other comprehensive income (loss) and reclassified into earnings in the same period or periods during which the hedged transaction affects earnings. Gains and losses on the derivative representing hedge ineffectiveness are recognized in current earnings within derivative and other gains (losses). AllIn cash flow hedges, all components of each derivative's gain or loss are included in the assessment of hedge effectiveness. Periodic
For derivative net coupon settlementsinstruments that are designated and qualify as fair value hedges, the gain or loss on the hedged item and the portion of the hedging instrument included in the assessment of effectiveness are recorded in the line item of the consolidated statements of earnings in which the cash flows ofgain or loss on the hedged item areis recorded.
For assessing hedge effectiveness of fair value hedges, qualitative methods may include the comparison of critical terms of the derivative to the hedged item, and quantitative methods may include regression or other statistical analysis of changes in fair value associated with the hedge relationship. Hedge ineffectiveness of the hedge relationships is measured each reporting period using the dollar offset method. For derivative instruments that are designated and qualify as fair value hedges, changes in the estimated fair value of the derivative, including amounts measured as ineffectiveness, and changes in the estimated fair value of the hedged item related to the designated risk being hedged, are reported in current earnings within derivative and other gains (losses).

For interest rate swaptions designated under fair value hedges of interest rate risk, the change in the time value of money is recognized in other comprehensive income (loss) and amortized into earnings (net investment income) over its legal term.
ForAs discussed in Note 4, from time to time the hedgeCompany designates net investment hedges of the Company'sits net investment in Aflac Japan, the Company has designated the majority of the Parent Company's yen-denominated liabilities (notes payable and yen-denominated loans) as non-derivative hedging instruments and has designated certain foreign currency forwards and options as derivative hedging instruments.Japan. The Company makes its net investment hedge designation at the beginning of each quarter. For assessing hedge effectiveness ofderivative hedging instruments designated as net investment hedges, ifAflac follows the totalspot-rate method. According to that method, the change in fair value of the designated Parent Company non-derivative and derivatives notionalhedging instrument due to fluctuations in the spot exchange rate is equal to or less than its net investment in Aflac Japan, the hedge is deemed to be effective. If the hedge is effective, the related exchange effect on the yen-denominated liabilities is reportedrecorded in the unrealized foreign currency component of other comprehensive income. For derivatives designated asincome and reclassified to earnings only when the hedged net investment hedges, Aflac followsis sold, or when a liquidation of the forward-rate method. According to that method, allrespective net investment in the foreign entity is substantially completed. If and when a sale or liquidation occurs, the changes in fair value including changes related toof the forward-rate component of foreign currency forward contracts and the time value of foreign currency options, are reportedderivative deferred in the unrealized foreign currency component of other comprehensive income.income will be released in the same income statement line item where the gain (loss) on the hedged net investment would be recorded upon sale. All other changes in fair value of the hedging instrument are considered the “excluded component” and are accounted for in realized investment gains (losses). Should these designated net investment hedge positions exceed the Company's net investment in Aflac Japan, the foreign exchange effect on the portion that exceeds its investment in Aflac Japan would be recognized in current earnings within derivative and otherrealized investment gains (losses).
The Company discontinues hedge accounting prospectively when (1) it is determined that the derivative is no longer highly effective in offsetting changes in the estimated cash flows or fair value of a hedged item; (2) the derivative is de-designated as a hedging instrument; or (3) the derivative expires or is sold, terminated or exercised.
When hedge accounting is discontinued on a cash flow hedge or fair value hedge, the derivative is carried in the consolidated balance sheets at its estimated fair value, with changes in estimated fair value recognized in current period earnings. For discontinued cash flow hedges, including those where the derivative is sold, terminated or exercised, amounts previously deferred in other comprehensive income (loss) are reclassified into earnings when earnings are impacted by the cash flow of the hedged item.
If a derivative is not designated as an accounting hedge or its use in managing risk does not qualify for hedge accounting, changes in the estimated fair value of the derivative are generally reported within derivative and other gains (losses), which is a component of realized investment gains (losses). The fluctuations in estimated fair value of derivatives that have not been designated for hedge accounting can result in volatility in net earnings.

The Company receives and pledges cash or other securities as collateral on open derivative positions. Cash received as collateral is reported as an asset with a corresponding liability for the return of the collateral. Cash pledged as collateral is recorded as a reduction to cash, and a corresponding receivable is recognized for the return of the cash collateral. The Company generally can repledge or resell collateral obtained from counterparties, although the Company does not typically exercise such rights. Securities received as collateral are not recognized unless the Company was to exercise its right to sell that collateral or exercise remedies on that collateral upon a counterparty default. Securities that the Company has pledged as collateral continue to be carried as investment assets on its balance sheet.


Deferred Policy Acquisition Costs:Certain direct and incremental costs of acquiring new business are deferred and amortized with interest over the premium payment periods in proportion to the ratio of annual premium income to total anticipated premium income. Anticipated premium income is estimated by using the same mortality, persistency and interest assumptions used in computing liabilities for future policy benefits. In this manner, the related acquisition expenses are matched with revenues. Deferred costs include the excess of current-year commissions over ultimate renewal-year commissions and certain incremental direct policy issue, underwriting and sales expenses. All of these incremental costs are directly related to successful policy acquisition.


For some products, policyholders can elect to modify product benefits, features, rights or coverages by exchanging a contract for a new contract or by amendment, endorsement, or rider to a contract, or by the election of a feature or coverage within a contract. These transactions are known as internal replacements. The Company performs a two-stage analysis of the internal replacements to determine if the modification is substantive to the base policy. The stages of evaluation are as follows: 1) determine if the modification is integrated with the base policy, and 2) if it is integrated, determine if the resulting contract is substantially changed.
For internal replacement transactions where the resulting contract is substantially unchanged, the policy is accounted for as a continuation of the replaced contract. Unamortized deferred acquisition costs from the original policy continue to be amortized over the expected life of the new policy, and the costs of replacing the policy are accounted for as policy maintenance

91


Item 8. Financial Statements and Supplementary Data


costs and expensed as incurred. Examples include conversions of same age bands, certain family coverage changes, pricing era changes (decrease), and ordinary life becomes reduced paid-up and certain reinstatements.
An internal replacement transaction that results in a policy that is substantially changed is accounted for as an extinguishment of the original policy and the issuance of a new policy. Unamortized deferred acquisition costs on the original policy are immediately expensed, and the costs of acquiring the new policy are capitalized and amortized in accordance with the Company's accounting policies for deferred acquisition costs. Further, the policy reserves are evaluated based on the new policy features, and any change (up or down) necessary is recognized at the date of contract change/modification. Examples include conversions-higherconversions to higher age bands, certain family coverage changes, pricing era changes (increase), lapse & re-issue, certain reinstatements and certain other contract conversions.
Riders can be considered internal replacements that are either integrated or non-integrated resulting in either substantially changed or substantially unchanged treatment. Riders are evaluated based on the specific facts and circumstances of the rider and are considered an expansion of the existing benefits with additional premium required. Non-integrated riders to existing contracts do not change the Company's profit expectations for the related products and are treated as a new policy establishment for incremental coverage.
The Company measures the recoverability of DAC and the adequacy of its policy reserves annually by performing gross premium valuations on its business. (See the following discussion for further information regarding policy reserves.)
Policy Liabilities: Future policy benefits represent claims that are expected to occur in the future and are computed byfollowing a net level premium method using estimated future investment yields, persistency and recognized morbidity and mortality tables modified to reflect the Company's experience, including a provision for adverse deviation. These assumptions are generally established and considered locked at policy inception. These assumptions may only be unlocked in certain circumstances based on the results of periodic DAC recoverability and premium deficiency testing.
Unpaid policy claims are estimates computed primarily on an undiscounted basis using statistical analyses of historical claims experience adjusted for current trends and changed conditions. The ultimate liability may vary significantly from such estimates. The Company regularly adjusts these estimates as new claims experience emerges and reflects the changes in operating results in the year such adjustments are made.



93



Other policy liabilitiesUnearned premiums consist primarily of discounted advance premiums on deposit from policyholders in conjunction with their purchase of certain Aflac Japan limited-pay insurance products. These advanced premiums are deferred upon collection and recognized as premium revenue over the contractual premium payment period.


Other policyholders’ funds liability consists primarily of the fixed annuity line of business in Aflac Japan which has fixed benefits and premiums.

For internal replacements that are determined to not be substantially unchanged, policy liabilities related to the original policy that was replaced are immediately released, and policy liabilities are established for the new insurance contract; however, for internal replacements that are considered substantially unchanged, no changes to the reserves are recognized.


Reinsurance: The Company enters into reinsurance agreements with other companies in the normal course of business. For each reinsurance agreement, the Company determines if the agreement provides indemnification against loss or liability relating to insurance risk in accordance with applicable accounting standards. Reinsurance premiums and benefits paid or provided are accounted for on bases consistent with those used in accounting for the original policies issued and the terms of the reinsurance contracts. Premiums, benefits and DAC are reported net of insurance ceded.


Income Taxes:Income tax provisions are generally based on pretax earnings reported for financial statement purposes, which differ from those amounts used in preparing the Company's income tax returns. Deferred income taxes are recognized for temporary differences between the financial reporting basis and income tax basis of assets and liabilities, based on enacted tax laws and statutory tax rates applicable to the periods in which the Company expects the temporary differences to reverse. The Company records deferred tax assets for tax positions taken based on its assessment of whether the tax position is more likely than not to be sustained upon examination by taxing authorities. A valuation allowance is established for deferred tax assets when it is more likely than not that an amount will not be realized.


Policyholder Protection Corporation and State Guaranty Association Assessments:In Japan, the government has required the insurance industry to contribute to a policyholder protection corporation. The Company recognizes a charge for

92


Item 8. Financial Statements and Supplementary Data


its estimated share of the industry's obligation once it is determinable. The Company reviews the estimated liability for policyholder protection corporation contributions on an annual basis and reports any adjustments in Aflac Japan's expenses.


In the United States,U.S., each state has a guaranty association that supports insolvent insurers operating in those states. The Company's policy is to accrue assessments when the entity for which the insolvency relates has met its state of domicile's statutory definition of insolvency, the amount of the loss is reasonably estimable and the related premium upon which the assessment is based is written. See Note 15 of the Notes to the Consolidated Financial Statements for further discussion of the guaranty fund assessments charged to the Company.


Treasury Stock:Treasury stock is reflected as a reduction of shareholders' equity at cost. The Company uses the weighted-average purchase cost to determine the cost of treasury stock that is reissued. The Company includes any gains and losses in additional paid-in capital when treasury stock is reissued.


Share-Based Compensation:The Company measures compensation cost related to its share-based payment transactions at fair value on the grant date, and the Company recognizes those costs in the financial statements over the vesting period during which the employee provides service in exchange for the award. The Company has formalized its entity-wide accounting policy election to estimate the number of awards that are expected to vest and the corresponding forfeitures.


Earnings Per Share:The Company computes basic earnings per share (EPS) by dividing net earnings by the weighted-average number of unrestricted shares outstanding for the period. Diluted EPS is computed by dividing net earnings by the weighted-average number of shares outstanding for the period plus the shares representing the dilutive effect of share-based awards.


Reclassifications:Certain reclassifications have been made to prior-year amounts to conform to current-year reporting classifications. These reclassifications had no impact on net earnings or total shareholders' equity.

Prior year foreign currency transaction gains and losses have been reclassified from Other income (loss) to Realized investment gains (losses) - Derivative and other gains (losses) to conform to current-year reporting classifications. These reclassifications had no impact on net earnings or total shareholders' equity. This change in classification was made to reflect that the major source of the Company's foreign currency transaction gains and losses is directly or indirectly a result of its investment activity.

In February 2018, the FASB issued amendments which allow a reclassification from accumulated other comprehensive income (AOCI) to retained earnings of the effects of the change in the U.S. federal income tax rate resulting from the Tax Cuts and Jobs Act (Tax Act) on the gross deferred tax amounts and the corresponding valuation allowances related to items remaining in AOCI. The amendments eliminate the stranded tax effects resulting from the Tax Act and also require certain disclosures about the reclassified tax effects.Early adopted as of January 1, 2018
The amounts reclassified from
AOCI to retained earnings include the income tax effects of the change in the federal corporate tax rate enacted by the Tax Act. The Company’s policy is to follow the portfolio approach for releasing income tax effects from AOCI. The adoption of this guidance resulted in an increase to beginning 2018 AOCI of $374 million with a corresponding decrease to beginning 2018 retained earnings as of January 1, 2018.

In March 2017, the FASB issued amendments requiring that an employer report the service cost component of net periodic pension cost and net periodic postretirement benefit cost in the same line item or items as other compensation costs arising from services rendered by the pertinent employees during the period. The other components of net periodic pension cost and net periodic postretirement benefit cost are required to be presented in the income statement separately from the service cost component and outside a subtotal of income from operations, if one is presented. If a separate line item or items are used to present the other components of net benefit cost, that line item or items must be appropriately described. If a separate line item or items are not used, the line item or items used in the income statement to present the other components of net benefit cost must be disclosed. The amendments in this update also allow only the service cost component to be eligible for capitalization when applicable.January 1, 2018The adoption of this guidance did not have a significant impact on the Company's financial position, results of operations, or disclosures.

Business Combinations: Clarifying the Definition of a Business
In January 2017, the FASB issued amendments clarifying when a set of assets and activities is a business. The amendments provide a screen to exclude transactions where substantially all the fair value of the transferred set is concentrated in a single asset, or group of similar assets, from being evaluated as a business.January 1, 2018The adoption of this guidance did not have a significant impact on the Company's financial position, results of operations, or disclosures.

The guidance requires certain reclassifications of balances on the statement of cash flows to or from operating and financing activities. The reclassification guidance did not have a significant impact on the Company's statement of cash flows.

The amendment allows an entity to elect whether to use estimates of forfeitures, or to account for forfeitures as they occur, using modified retrospective application. The Company adopted this guidance as of January 1, 2017. The Company made an entity-wide accounting policy election to estimate the number of awards that are expected to vest (consistent with the Company's prior policy). The election and adoption of this guidance did not have a significant impact on the Company's financial position, results of operations, or disclosures.

Investments - Equity Method and Joint Ventures - Simplifying the Transition to the Equity Method of Accounting: In March 2016, the FASB issued amendments which eliminate the requirement that when an investment qualifies for use of the equity method as a result of an increase in the level of ownership interest or degree of influence, an investor must adjust the investment, results of operations, and retained earnings retroactively on a step-by-step basis as if the equity method had been in effect during all previous periods that the investment had been held. Per the amendments, upon qualifying for the equity method of accounting, no retroactive adjustment of the investment is required. The amendments also require that an entity that has an available-for-sale equity security that becomes qualified for the equity method of accounting recognize through earnings the unrealized holding gain or loss in accumulated other comprehensive income at the date the investment becomes qualified for use of the equity method.

Business Combinations - Simplifying the Accounting for Measurement-Period Adjustments: In September 2015, the FASB issued guidance requiring that an acquirer recognize adjustments to estimated amounts that are identified during the measurement period in the reporting period in which the adjustments are determined. In the same period’s financial statements, the acquirer is required to record income effects of the adjustments as if the accounting had been completed at the acquisition date. The acquirer is also required to present separately on the face of the income statement or disclose in the notes the portion of the amount recorded in current-period earnings by line item that would have been recorded in previous reporting periods if the adjustment to the estimated amounts had been recognized as of the acquisition date. The Company adopted this guidance as of January 1, 2016. The adoption of this guidance did not have a significant impact on the Company's financial position, results of operations, or disclosures.

Financial Services - Insurance - Disclosures about Short-Duration Contracts: In May 2015, the FASB issued updated guidance requiring enhanced disclosures by all insurance entities that issue short-duration contracts. The amendments require insurance entities to disclose for annual reporting periods information about the liability for unpaid claims and claim adjustment expenses. The amendments also require insurance entities to disclose information about significant changes in methodologies and assumptions used to calculate the liability for unpaid claims and claim adjustment expenses. In addition, the amendments require insurance entities to disclose for annual and interim reporting periods a roll-forward of the liability for unpaid claims and claim adjustment expenses. For health insurance claims, the amendments require the disclosure of the total of incurred-but-not-reported liabilities and expected development on reported claims included in the liability for unpaid claims and claim adjustment expenses. The Company adopted this guidance as of December 31, 2016. The adoption of this guidance did not have a significant impact on the Company's disclosures.

Fair Value Measurement - Disclosures for Investments in Certain Entities That Calculate Net Asset Value per Share (or Its Equivalent): In May 2015, the FASB issued updated guidance that removes the requirement to categorize within the fair value hierarchy all investments for which fair value is measured using the net asset value per share practical expedient. The amendments also remove the requirement to make certain disclosures for all investments that are eligible to be measured at fair value using the net asset value per share practical expedient. Rather, those disclosures are limited to investments for which the entity has elected to measure the fair value using that practical expedient. The Company adopted this guidance as of January 1, 2016. The adoption of this guidance did not have a significant impact on the Company's disclosures.

Interest - Imputation of Interest - Simplifying the Presentation of Debt Issuance Costs: In April 2015, the FASB issued updated guidance to simplify presentation of debt issuance costs. The updated guidance requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. The recognition and measurement guidance for debt issuance costs are not affected by this amendment. In August 2015, the FASB issued updated Securities and Exchange Commission (SEC) Staff guidance pertaining to the presentation of debt issuance costs related to line-of-credit arrangements. The guidance states that an entity may defer and present debt issuance costs as an asset, subsequently amortizing the deferred debt issuance costs ratably over the term of the line-of-credit arrangement, regardless of whether there are any outstanding borrowings on the line-of-credit arrangement. The Company retrospectively adopted this guidance as of January 1, 2016. The retrospective adoption of this accounting standard resulted in a $40 million reduction to notes payable and other assets as of December 31, 2015, the earliest balance sheet date presented in the period of adoption, but did not have a significant impact on the Company's financial position, results of operations, or disclosures.

Consolidation - Amendments to the Consolidation Analysis: In February 2015, the FASB issued updated guidance that affects evaluation of whether limited partnerships and similar legal entities (limited liability corporations and securitization structures, etc.) are VIEs, evaluation of whether fees paid to a decision maker or a service provider are a variable interest, and evaluation of the effect of fee arrangements and the effect of related parties on the determination of the primary beneficiary under the VIE model for consolidation. The updated guidance eliminates the presumption that a general partner should consolidate a limited partnership. Limited partnership and similar legal entities that provide


96




partners with either substantive kick-out rights or substantive participating rights over the general partner will now be evaluated under the voting interest model rather than the VIE model for consolidation. In situations where no single party has a controlling financial interest in a VIE, the related party relationships under common control should be considered in their entirety in determining whether that common control group has a controlling financial interest in the VIE. The Company adopted this guidance as of January 1, 2016. The adoption of this guidance impacted the Company's footnote disclosures, but did not have a significant impact on its financial position or results of operations.

Derivatives and Hedging - Determining Whether the Host Contract in a Hybrid Financial Instrument Issued in the Form of a Share Is More Akin to Debt or to Equity: In November 2014, the FASB issued guidance to clarify how to evaluate the economic characteristics and risks of a host contract in a hybrid financial instrument that is issued in the form of a share. The guidance also clarifies that an entity should assess the substance of the relevant terms and features when considering how to weight those terms and features. The Company adopted this guidance as of January 1, 2016. The adoption of this guidance did not have a significant impact on the Company's financial position, results of operations, or disclosures.

Presentation ofItem 8. Financial Statements - Going Concern - Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern: In August 2014, the FASB issued this amendment that provides U.S. GAAP guidance on management’s responsibility in evaluating whether there is substantial doubt about a company’s ability to continue as a going concern and about related footnote disclosures. For each reporting period, management will be required to evaluate whether there are conditions or events that raise substantial doubt about a company’s ability to continue as a going concern within one year from the date the financial statements are issued. The new guidance requires a formal assessment of going concern by management based on criteria prescribed in the new guidance. The Company adopted this guidance as of December 31, 2016. The adoption of this guidance did not have a significant impact on the Company's financial position, results of operations, or disclosures, and no substantial doubt currently exists about the Company’s ability to continue as a going concern. Supplementary Data


Compensation - Stock Compensation - Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period: In June 2014, the FASB issued this amendment that provides guidance on certain share-based payment awards that require a specific performance target that affects vesting and that could be achieved after the requisite service period be treated as a performance condition. A reporting entity should apply existing guidance to awards with performance conditions that affect vesting to account for such awards. Compensation cost should be recognized in the period in which it becomes probable that the performance target will be achieved and should represent the compensation cost attributable to the period(s) for which the requisite service has already been rendered. The total amount of compensation cost recognized during and after the requisite service period should reflect the number of awards that are expected to vest and should be adjusted to reflect those awards that ultimately vest.

ASU 2018-11, Leases, Targeted Improvements, and
ASU 2018-20, Leases: Narrow-Scope Improvements for Lessors
In February 2016, the FASB issued updated guidance for accounting for leases (“Leases Update”). Per the Leases Update, lessees are required to recognize all leases on the balance sheet with the exception of short-term leases. A lease liability will be recorded for the obligation of a lessee to make lease payments arising from a lease. Leases will be classified as finance or operating, with classification affecting the pattern and classification of expense recognition in the income statement. The Leases Update provided a number of optional practical expedients. The Company elected the "package of practical expedients," which permits the Company not to reassess under the new standard its prior conclusions about lease identification, lease classification and initial direct costs. Under the Leases Update, lessor accounting is largely unchanged.

In January 2018, an amendment was issued to the Leases Update which provided an entity with the option to elect a transition practical expedient to not evaluate land easements that exist or expired before the entity's adoption of the Leases Update and that were not previously accounted for as leases.

In July 2018, the FASB issued two amendments to the Leases Update which clarified, corrected errors in, or made minor improvements to the Leases Update and provided entities with an optional transition method to adopt the Leases Update by recording a cumulative-effect adjustment to beginning retained earnings. Additionally, the amendments provided lessors with a practical expedient to not separate nonlease components from associated lease components and instead account for those components as a single component under certain conditions.

In December 2018, an amendment to the Leases Update was issued to clarify: 1) lessor accounting for all sales (and other similar) taxes; 2) the handling of certain lessor costs when the amount of those costs is not readily determinable; and 3) lessor allocation of certain variable payments to the lease and non-lease components.
January 1, 2019
The Company has operating and finance leases for office space and equipment. The Company elected the short-term lease exemption for all classes of leases which allows the Company to not recognize right-of-use assets and lease liabilities on the consolidated balance sheet and allows the Company to recognize the lease expense for short-term leases on a straight-line basis over the lease term. The Company elected the practical expedient to not separate lease and non-lease components and applied it to all classes of leases where the non-lease components are not significant. Some of the Company's leases include options to extend or terminate the lease and the lease terms may include such options when it is reasonably certain that the Company will exercise that option. Certain leases also include options to purchase the leased property. The leases within scope of the leases update increased the Company's right-of-use assets and lease liabilities recorded in its consolidated balance sheet by $134 million.

As of January 1, 2019, the Company did not have land easements, but has elected the practical expedient as a safe harbor.

The Company elected the optional transition method and as a safe harbor, the practical expedient provided to lessors.
 
The Company has made an accounting policy election to exclude amounts collected from customers for all sales (and other similar) taxes from the transaction price.

In January 2016, the FASB issued guidance to address certain aspects of recognition, measurement, presentation, and disclosure of financial instruments. The main provisions of this guidance require certain equity investments to be measured at fair value with changes in fair value recognized in net earnings; separate presentation in other comprehensive income for changes in fair value of financial liabilities measured under the fair value option that are due to instrument-specific credit risk; and changes in disclosures associated with the fair value of financial instruments. The guidance also clarifies that entities should evaluate the need for a valuation allowance on a deferred tax asset (DTA) related to available-for-sale (AFS) securities in combination with the entity's other DTAs.January 1, 2018The Company recorded a cumulative effect adjustment with an increase to beginning 2018 retained earnings and a decrease to beginning 2018 AOCI of $148 million, net of taxes.

Clarifying the interactions between Topic 321, Topic 323, and Topic 815

In January 2020, the FASB issued amendments clarifying that an entity should consider observable transactions that require it to either apply or discontinue the equity method of accounting for the purposes of applying the measurement alternative in accordance with Topic 321 immediately before applying or upon discontinuing the equity method.

In addition, the amendments clarify that for the purpose of applying certain derivative guidance in Topic 815, an entity should not consider whether, upon the settlement of the forward contract or exercise of the purchased option, individually or with existing investments, the underlying securities would be accounted for under the equity method in Topic 323 or the fair value option in accordance with the financial instruments guidance in Topic 825. An entity also would evaluate the remaining characteristics in Topic 815 to determine the accounting for those forward contracts and purchased options.

The amendments are effective for public business entities for fiscal years beginning after December 15, 2020, and interim periods within those fiscal years. Early adoption is permitted.
The adoption of this guidance is not expected to have a significant impact on the Company's financial position, results of operations, or disclosures.

Income Statement - Reporting Comprehensive Income - Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income: In February 2018, the FASB issued amendments which allow a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the Tax Cuts and Jobs Act. The amendments eliminate the stranded tax effects resulting from the Tax Cuts and Jobs Act and also require certain disclosures about stranded tax effects. The amendments are effective for all entities for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. Public business entities may early adopt this guidance in any interim reporting period for which financial statements have not yet been issued. The amendments should be applied either in the period of adoption or retrospectively to each period (or periods) in which the effect of the change in the U.S. federal corporate income tax rate in the Tax Cuts and Jobs Act is recognized. The Company expects adoption of this guidance will result in an increase to accumulated other comprehensive income and a decrease to retained earnings and also result in additional disclosures.

Leases - Land Easement Practical Expedient for Transition to Topic 842: In January 2018, FASB issued guidance which provides an entity with the option to elect a transition practical expedient to not evaluate, under Topic 842, land easements that exist or expired before the entity's adoption of Topic 842 and that were not previously accounted for as leases under Topic 840. The amendments clarify that new or modified land easements should be evaluated under the new leases standard once an entity has adopted the new standard. The amendments are effective for public business entities for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. Early adoption is permitted. The adoption of this guidance is not expected to have a significant impact on the Company's financial position, results of operations, or disclosures.

Derivatives and Hedging - Targeted Improvements to Accounting for Hedging Activities: In August 2017, FASB issued guidance which improves and simplifies the accounting rules around hedge accounting and will create more transparency around how economic results are presented on financial statements. Issues addressed in this new guidance include: 1) risk component hedging, 2) accounting for the hedged item in fair value hedges of interest rate risk, 3) recognition and presentation of the effects of hedging instruments, and 4) amounts excluded from the assessment of hedge effectiveness. The amendments are effective for public business entities for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. Early adoption is permitted in any interim period after issuance of the guidance. The adoption of this guidance is not expected to have a significant impact on the Company's financial position, results of operations, or disclosures.

Compensation-Stock Compensation: Scope of Modification Accounting: In May 2017, the FASB issued amendments to provide guidance clarifying when changes to the terms or conditions of a share-based payment award must be accounted for as modifications. An entity should apply modification accounting if the fair value, vesting conditions or classification of the award (as an equity instrument or liability instrument) changes as a result of the change in terms or conditions of the award. The amendments are effective for public business entities for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. Early adoption is permitted and should be applied prospectively. The adoption of this guidance is not expected to have a significant impact on the Company's financial position, results of operations, or disclosures.

Receivables-Nonrefundable Fees and Other Costs: Premium Amortization on Purchased Callable Debt Securities: In March 2017, the FASB issued amendments to shorten the amortization period for certain callable debt securities held at a premium. Specifically, the amendments require the premium to be amortized to the earliest call date. The amendments do not require an accounting change for securities held at a discount. The amendments are effective for public business entities for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. Early adoption is permitted, including adoption in an interim period. The adoption of this guidance is not expected to have a significant impact on the Company's financial position, results of operations, or disclosures.

The other components of net periodic pension cost and net periodic postretirement benefit cost are required to be presented in the income statement separately from the service cost component and outside a subtotal of income from operations, if one is presented. If a separate line item or items are used to present the other components of net benefit cost, that line item or items must be appropriately described. If a separate line item or items are not used, the line item or items used in the income statement to present the other components of net benefit cost must be disclosed. The amendments in this update also allow only the service cost component to be eligible for capitalization when applicable. The amendments are effective for public business entities for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. Early adoption is permitted. The adoption of this guidance is not expected to have a significant impact on the Company's financial position, results of operations, disclosures, or statements of cash flows.

Other Income - Gains and Losses from the Derecognition of Nonfinancial Assets - Clarifying the Scope of Asset Derecognition Guidance and Accounting for Partial Sales of Nonfinancial Assets: In February 2017, the FASB issued amendments that clarify the scope and accounting guidance for the derecognition of a nonfinancial asset or a financial asset that meets the definition of an "in substance nonfinancial asset." The amendments define an "in substance nonfinancial asset" and provide additional accounting guidance for partial sales of nonfinancial assets. The amendments are effective for public business entities for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. Earlier adoption is permitted for fiscal years beginning after December 15, 2016, including interim periods therein. An entity is required to apply the amendments at the same time that it applies the FASB amendments for Revenue from Contracts with Customers. The Company does not expect the adoption of this guidance to have a significant impact on its financial position, results of operations, disclosures, and statements of cash flows.

Intangibles - Goodwill and Other - Simplifying the Test for Goodwill Impairment: In January 2017, the FASB issued amendments simplifying the subsequent measurement of goodwill. An entity, under this update, is no longer required to perform a hypothetical purchase price allocation to measure goodwill impairment. Instead, the entity should perform its annual or interim goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. The amendments are effective for public business entities that are SEC filers for annual or any interim goodwill impairment tests in fiscal years beginning after December 15, 2019. Early adoption is permitted for any goodwill impairment tests performed on testing dates after January 1, 2017. The Company does not expect the adoption of this guidance to have a significant impact on its financial position, results of operations, or disclosures.

Business Combinations - Clarifying the Definition of a Business: In January 2017, the FASB issued amendments clarifying when a set of assets and activities is a business. The amendments provide a screen to exclude transactions where substantially all the fair value of the transferred set is concentrated in a single asset, or group of similar assets, from being evaluated as a business. The amendments are effective for public business entities beginning after December 15, 2017, including interim periods within those periods. The Company does not expect the adoption of this guidance to have a significant impact on its financial position, results of operations, or disclosures.

Statement of Cash Flows - Restricted Cash: In November 2016, the FASB issued amendments requiring that a statement of cash flows explain the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. The amendments are effective for public business entities for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. Early adoption is permitted. The Company does not expect the adoption of this guidance to have a significant impact on its financial position, results of operations, disclosures, or statement of cash flows.

Income Taxes - Intra-Entity Transfers of Assets Other Than Inventory: In October 2016, the FASB issued amendments that require an entity to recognize the income tax consequences of an intra-entity transfer of an asset other than inventory when the transfer occurs. The amendments are effective for public business entities for annual reporting periods beginning after December 15, 2017, including interim reporting periods within those annual reporting periods. Early adoption is permitted. The Company does not expect the adoption of this guidance to have a significant impact on its financial position, results of operations, and disclosures.

Statement of Cash Flows - Classification of Certain Cash Receipts and Cash Payments: In August 2016, the FASB issued amendments that provide guidance on eight specific statement of cash flows classification issues. The amendments are effective for public companies for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. Early adoption is permitted for any interim or annual period. The adoption of this guidance is not expected to have a significant impact on the Company's financial position, results of operations, disclosures, or statements of cash flows.

Financial Instruments - Credit Losses - Measurement of Credit Losses on Financial Instruments: In June 2016, the FASB issued amendments that require a financial asset (or a group of financial assets) measured on an amortized cost basis to be presented net of an allowance for credit losses in order to reflect the amount expected to be collected on the financial asset(s). The measurement of expected credit losses is amended by replacing the incurred loss impairment methodology in current U.S. GAAP with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform about a credit loss. Credit losses on available-for-sale debt securities will continue to be measured in a manner similar to current U.S. GAAP. However, the amendments require that credit losses be presented as an allowance rather than as a writedown. Other amendments include changes to the balance sheet presentation and interest income recognition of purchased financial assets with a more-than-insignificant amount of credit deterioration since origination. The amendments are effective for public companies for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. Companies may early adopt this guidance as of the fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. The Company has identified certain financial instruments in scope of this guidance to include certain fixed maturity securities, loans and loan receivables and reinsurance recoverables (See Notes 3 and 7 for current balances of instruments in scope). The Company is continuing its progress towards updating its credit loss projection models and accounting systems in order to comply with the required changes in measurement of credit losses. The Company currently expects loans and loan receivables and held-to-maturity fixed-maturity securities to be the asset classes most significantly impacted upon adoption of the guidance. The Company continues to evaluate the impact of adoption of this guidance on its financial position, results of operations, and disclosures.

Leases: In February 2016, the FASB issued updated guidance for accounting for leases. Per the amendments, lessees will be required to recognize all leases on the balance sheet with the exception of short-term leases. A lease liability will be recorded for the obligation of a lessee to make lease payments arising from a lease. A right-of-use asset will be recorded which represents the lessee’s right to use, or to control the use of, a specified asset for a lease term. Under the new guidance, lessor accounting is largely unchanged. The amendments are effective for public companies for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early adoption is permitted, including adoption in an interim period. The Company has identified certain operating leases in scope of this guidance to include office space and equipment leases (See Note 15 of the Notes to the ConsolidatedItem 8. Financial Statements in the 2016 Annual Report for current balances of leases in scope). The leases within scope of this guidance will increase the Company's right-of-use assets and lease liabilities recorded on its statement of financial position, however the Company estimates leases within scope of the guidance to represent less than 1% of its total assets as of December 31, 2017. The Company estimates that the adoption of this guidance will not have a significant impact on its financial position, results of operations, and disclosures.Supplementary Data


Financial Instruments - Overall - Recognition and Measurement of Financial Assets and Financial Liabilities: In January 2016, the FASB issued guidance to address certain aspects of recognition, measurement, presentation, and disclosure of financial instruments. The main provisions of this guidance require certain equity investments to be measured at fair value with changes in fair value recognized in net earnings; separate presentation in other comprehensive income for changes in fair value of financial liabilities measured under the fair value option that are due to instrument-specific credit risk; and changes in disclosures associated with the fair value of financial instruments. The guidance also clarifies that entities should evaluate the need for a valuation allowance on a deferred tax asset (DTA) related to available-for-sale (AFS) securities in combination with the entity's other DTAs. The amendments are effective for public companies for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. Early adoption is not permitted, with the exception of the own credit provision if an entity has elected to measure a liability at fair value. The Company has determined that the most significant impact of adopting this guidance will be the requirement to report changes in fair value in net earnings for all equity investments within scope of this guidance. The Company estimates the cumulative effect adjustment of adopting this guidance will increase beginning 2018 retained earnings and decrease beginning 2018 accumulated other comprehensive income by $133 million, net of taxes. The Company also expects that the adoption of this guidance may potentially increase volatility in its consolidated statements of earnings on a prospective basis.

Codification Improvements to Topic 326, Financial Instruments - Credit Losses, Topic 815, Derivatives and Hedging, and Topic 825, Financial Instruments
In April 2019, the FASB issued Codification improvements to clarify and correct certain areas of guidance amended as part of ASU 2016-01, Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities; ASU 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments; and ASU 2017-12, Derivative and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities.  

The most significant of these improvements to the Company was related to the Codification improvement to ASU 2017-12 and the clarification that a one-time reclassification of assets that are eligible to be hedged under the last-of-layer method (i.e., certain pre-payable securities) from held-to-maturity to available-for-sale is allowed under the new hedge accounting guidance and would not impact the Company’s ability to continue to classify other bonds as held-to-maturity. This clarification is effective for the Company beginning January 1, 2020, with early adoption permitted. If a reclassification is elected, it must be reflected as of the date of adoption of this update.

The other amendments related to ASU 2017-12 and 2016-01 are either not significant, or were previously implemented as part of the related ASU adoptions.

Applicable amendments related to ASU 2016-13 are discussed within the pending adoption of that update below.



The Company did not reclassify any assets from held-to-maturity to available-for-sale as part of its implementation of ASU 2017-12, and is therefore eligible to reclassify qualifying securities as a result of these clarifications. Effective on January 1, 2020, the Company anticipates the reclassification of approximately $6.9 billion (at amortized cost) of pre-payable fixed-maturity securities from the held-to-maturity to the available-for-sale category. This reclassification is expected to result in recording in accumulated other comprehensive income a net unrealized gain of approximately $800 million on an after-tax basis, based on the securities’ fair values on the reclassification date. The reclassification will impact the adoption of ASU 2016-13 which will be effective January 1, 2020 (see ASU 2016-13 below for additional details).

ASU 2018-17 Consolidation: Targeted Improvements to Related Party Guidance for Variable Interest Entities
In October 2018, the FASB issued targeted improvements which provide that indirect interests held through related parties under common control should be considered on a proportional basis for determining whether fees paid to decision makers and service providers are variable interests. The amendments are effective for public business entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. Early adoption is permitted.
The adoption of this guidance is not expected to have a significant impact on the Company’s financial position, results of operations or disclosures.
ASU 2018-13
Fair Value Measurement, Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement
In August 2018, the FASB issued amendments to the disclosure requirements on fair value measurements. The amendments remove, modify, and add certain disclosures. The amendments are effective for all entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. Early adoption is permitted. Further, an entity is permitted to early adopt any removed or modified disclosures upon issuance of this update and delay adoption of the additional disclosures until their effective date.The adoption of this guidance is not expected to have a significant impact on the Company’s financial position, results of operations, or disclosures.

Revenue from Contracts with Customers: In May 2014, the FASB issued updated guidance that affects any entity that either enters into contracts with customers to transfer goods or services or enters into contracts for the transfer of nonfinancial assets unless those contracts are within the scope of other standards (e.g., insurance contracts or lease contracts). The core principle of the guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. In August 2015, the FASB deferred the effective date for this standard to annual reporting periods beginning after December 15, 2017, including interim periods within that reporting period. Earlier application is permitted only as of annual reporting periods beginning after December 15, 2016, including interim reporting periods. The Company has identified revenue in scope of this guidance to include certain revenues associated with

Financial Services - Insurance, Targeted Improvements to the Accounting for Long-Duration Contracts
as clarified and amended by:
ASU No. 2019-09,Financial Services Insurance (Topic 944)- Effective Date
In August 2018, the FASB issued amendments that will significantly change how insurers account for long-duration contracts. The amendments will change existing recognition, measurement, presentation, and disclosure requirements. Issues addressed in the new guidance include: 1) a requirement to review and, if there is a change, update assumptions for the liability for future policy benefits at least annually, and to update the discount rate assumption quarterly, 2) accounting for market risk benefits at fair value, 3) simplified amortization for deferred acquisition costs, and 4) enhanced financial statement presentation and disclosures.

In November 2019, the FASB issued an amendment extending the effective date for public business entities that meet the definition of an SEC filer, excluding entities eligible to be small reporting companies as defined by the SEC, by one year. The amendments are now effective for the Company for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2021. Early application of the amendments is permitted.

The Company is thoroughly evaluating the impact of adoption and expects that the adoption will have a significant impact on the Company’s financial position, results of operations, and disclosures. The Company anticipates that the requirement to update assumptions for liability for future policy benefits will have a significant impact on its results of operations, systems, processes and controls while the requirement to update the discount rate will have a significant impact on its equity. The Company has no products with market risk benefits. The Company does not expect to early adopt the updated standard and has tentatively selected a modified retrospective transition method.

Financial Instruments - Credit Losses: Measurement of Credit Losses on Financial Instruments

as clarified and amended by:
ASU 2019-04, Codification Improvements to Topic 326, Financial Instruments - Credit Losses, Topic 815, Derivatives and Hedging, and Topic 825, Financial Instruments,
ASU 2019-05, Financial Instruments - Credit Losses (Topic 326), Targeted Transition Relief
and
ASU 2019-11, Codification Improvements to Topic 326, Financial Instruments- Credit Losses

In June 2016, the FASB issued amendments that require a financial asset (or a group of financial assets) measured at amortized cost to be presented net of an allowance for credit losses (Credit Losses ASU) in order to reflect the amount expected to be collected on the financial asset(s). The measurement of expected credit losses is amended by replacing the incurred loss impairment methodology in current U.S. GAAP with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information. Credit losses on available-for-sale debt securities will be measured in a manner similar to current U.S. GAAP; however, the amendments require that credit losses be presented as an allowance rather than as a write-down. Other amendments include changes to the balance sheet presentation and interest income recognition of purchased financial assets with a more-than-insignificant credit deterioration since origination (PCD financial assets).

The Credit Losses ASU is effective for public companies for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. Companies may early adopt this guidance as of the fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. The amendments will be adopted following a modified-retrospective approach resulting in a cumulative effect adjustment in retained earnings as of the beginning of the year of adoption. Two exceptions to this adoption method are for PCD financial assets and debt securities for which other-than-temporary impairment (OTTI) will have been recognized before the effective date. Loans purchased with credit deterioration accounted for under current U.S. GAAP as "purchased credit impaired" (PCI) financial assets will be classified as PCD financial assets at transition and PCD guidance will be applied prospectively. Debt securities that have experienced OTTI before the effective date will follow a prospective adoption method which allows an entity to maintain the same amortized cost basis before and after the effective date.

In April 2019, the Credit Losses ASU was amended to allow entities to make a policy election about presentation and disclosure of accrued interest receivable and the related credit losses, whereby entities that write off uncollectible accrued interest receivable in a timely manner can make a policy election not to measure an allowance on the accrued interest receivable. Other amendments made within this Update clarify and address stakeholders’ specific issues about certain aspects of the Credit Losses ASU.

In May 2019, the FASB granted a targeted transition relief by allowing to irrevocably elect the fair value option for certain financial assets previously measured at amortized cost.

These amendments will be effective upon adoption of the Credit Losses ASU.
The Company has identified the following financial instruments in scope of the new guidance: certain fixed maturity securities, loans and loan receivables, reinsurance recoverable, as well as certain other receivable balances and off-balance sheet arrangements.

The Company has concluded that of the held-to-maturity fixed maturity securities, Japanese government and agency securities and certain Japanese government-guaranteed mortgage backed securities meet the requirements for a zero-loss expectation and therefore will not be included in the current expected credit loss measurement process upon adoption of the new standard.

The Company has substantially completed the review and validation of credit models, methodologies and inputs for all asset classes. The Company performed parallel runs during the second, third and fourth quarters and refined its estimation process with additional parallel testing throughout 2019. The Company has estimated the adoption-date net after-tax impact at a $56 million decrease to retained earnings. As noted above relative to ASU 2019-04, the Company is planning a one-time reclassification as of January 1, 2020 of approximately $6.9 billion (amortized cost as of December 31, 2019) of its eligible fixed-maturity securities from held-to-maturity to available-for-sale category. The aforementioned reclassification has been reflected in the expected impact estimate from adoption of ASU 2016-13. The Company plans to adopt this ASU on January 1, 2020.


Recent accounting guidance not discussed above is not applicable, did not have, or is not expected to have a material impact to the Company's business.

2.BUSINESS SEGMENT AND FOREIGN INFORMATION
The Company consists of two2 reportable insurance business segments: Aflac Japan and Aflac U.S., both of which sell supplemental health and life insurance. OperatingIn addition, operating business segmentsunits that are not individually reportable and business activities, including reinsurance retrocession activities, not included in Aflac Japan or Aflac U.S. are included in the "Other business segments" category.Corporate and other.


The Company does not allocate corporate overhead expenses to business segments. Consistent with U.S. GAAP accounting guidance for segment reporting, the Company evaluates and manages its business segments using a financial performance measure called pretax operatingadjusted earnings. Adjusted earnings are adjusted revenues less benefits and adjusted expenses. The Company's definition of operating earnings includes interest cash flows associated with notes payableadjustments to both revenues and amortized hedge costs related to foreign currency denominated investments, but excludesexpenses account for certain items that cannot be predicted or that are outside of the management's control, such asmanagement’s control. Adjusted revenues are U.S. GAAP total revenues excluding realized investment gains and losses, from securities transactions, impairments, change in loan loss reserves and certain derivative andexcept for amortized hedge costs/income related to foreign currency activities;exposure management strategies and net interest cash flows from derivatives associated with certain investment strategies. Adjusted expenses are U.S. GAAP total acquisition and operating expenses including the impact of interest cash flows from derivatives associated with notes payable but excluding any nonrecurring items; andor other non-operating income (loss) from net earnings. Nonrecurring and other non-operating items consist of infrequent events and activity not associated with the normal
course of the Company’s insurance operations and that do not reflect Aflac’s underlying business performance. The Company excludes income taxes related to operations to arrive at pretax operatingadjusted earnings.

Expected maturities may differ from contractual maturities because some issuers havefinancial instrument such as the right to call or prepay obligations with or without call or prepayment penalties.changes in coupon rates.

The majority of the Company's perpetual securities are subordinated to other debt obligations of the issuer, but rank higher than the issuer's equity securities. Perpetual securities have characteristics of both debt and equity investments, along with unique features that create economic maturity dates for the securities. Although perpetual securities have no contractual maturity date, they have stated interest coupons that were fixed at their issuance and subsequently change to a floating short-term interest rate after some period of time. The instruments are generally callable by the issuer at the time of changing from a fixed coupon rate to a new variable rate of interest, which is determined by the combination of some market index plus a fixed amount of basis points. The net effect is to create an expected maturity date for the instrument. The economic maturities of the Company's investments in perpetual securities, which were all reported as available for sale at December 31, 2017, were as follows:

Investment Concentrations


The Company's process for investing in credit-related investments begins with an independent approach to underwriting each issuer's fundamental credit quality. The Company evaluates independently those factors that it believes could influence an issuer's ability to make payments under the contractual terms of the Company's instruments. This includes a thorough analysis of a variety of items including the issuer's country of domicile (including political, legal, and financial considerations); the industry in which the issuer competes (with an analysis of industry structure, end-market dynamics, and regulation); company specific issues (such as management, assets, earnings, cash generation, and capital needs); and contractual provisions of the instrument (such as financial covenants and position in the capital structure). The Company further evaluates the investment considering broad business and portfolio management objectives, including asset/liability needs, portfolio diversification, and expected income.

Analysis of Securities in Unrealized Loss Positions


The unrealized losses on the Company's fixed maturity or perpetual securities investments have been primarily related to general market changes in interest rates, foreign exchange rates, and/or the levels of credit spreads rather than specific concerns with the issuer's ability to pay interest and repay principal. The unrealized losses on the Company's investments in equity securities are primarily related to foreign exchange rates, general market conditions which reflect prospects for the economy as a whole, or specific information pertaining to an industry or an individual company.

For corporate issuers, the Company evaluates their assets, business profile including industry dynamics and competitive positioning, financial statements and other available financial data. For non-corporate issuers, the Company analyzes all sources of credit support, including issuer-specific factors. The Company utilizes information available in the public domain and, for certain private placement issuers, from consultations with the issuers directly. The Company also considers ratings from Nationally Recognized Statistical Rating Organizations (NRSROs), as well as the specific characteristics of the security it owns including seniority in the issuer's capital structure, covenant predictions,protections, or other relevant features. From these reviews, the Company evaluates the issuers' continued ability to service the Company's investment through payment of interest and principal.

For any significant declines in fair value of its equity securities, the Company reviews the severity of the security’s decline in fair value coupled with the length of time the fair value of the security has been below cost. The Company also performs a more focused review of the financial condition and near-term prospects of the issuer as well as general market conditions reflecting the prospects for the economy as a whole, and determines whether it has the intent to hold the securities until they recover in value.


Assuming no credit-related factors develop, unrealized gains and losses on fixed maturities and perpetualmaturity securities are expected to diminish as investments near maturity. Based on its credit analysis, the Company believes that the issuers of its fixed maturity and perpetual security investments in the sectors shown in the table above have the ability to service their obligations to the Company.

Item 8. Financial Statements and Supplementary Data


Transitional Real Estate Loans

Transitional real estate loans are commercial mortgage loans that are typically relatively short-term floating rate instruments secured by a first lien on the property.These loans provide funding for properties undergoing a change in their physical characteristics and/or economic profile and do not typically require any principal repayment prior to the maturity date. This loan portfolio is generally considered to be investment grade. As of December 31, 2019, the Company had $875 millionin outstanding commitments to fund transitional real estate loans. These commitments are contingent on the final underwriting and due diligence to be performed.

Commercial Mortgage Loans

Commercial mortgage loans are typically fixed rate loans on commercial real estate with partial repayment of principal over the life of the loan with the remaining outstanding principal being repaid upon maturity. This loan portfolio is generally considered higher quality investment grade loans. As of December 31, 2019, the Company had $27 million of outstanding commitments to fund commercial mortgage loans. These commitments are contingent on the final underwriting and due diligence to be performed.

Middle Market Loans

Middle market loans are typically first lien senior secured cash flow loans to small to mid-size companies for working capital, refinancing, acquisition, and recapitalization. These loans are generally considered to be below investment grade. The carrying value for middle market loans included $99 million and $56 million for a short term credit facility that is reflected in other liabilities on the consolidated balance sheets, as of December 31, 2019, and 2018, respectively.

As of December 31, 2019, the Company had commitments of approximately $502 million to fund potential future loan originations related to this investment program. These commitments are contingent upon the availability of middle market loans that meet the Company's underwriting criteria.

Allowance for Loan Losses

The Company's allowance for loan losses is established using both general and specific allowances. The general allowance is used for loans grouped by similar risk characteristics where a loan-specific or market-specific risk has not been identified, but for which the Company estimates probable incurred losses. The specific allowance is used on an individual loan basis when it is probable that a loss has been incurred. As of December 31, 2019, the Company had loan loss reserves of $6 million related to 2 specific middle market loans. There was no specific loan loss reserve as of December 31, 2018. The following table presents the rollforward of the Company's allowance for loan losses by portfolio segment during the year ended December 31.

Allowance for loan losses at December 31, 2019 $(3)   $(22)   $(20)   $(45) 


As of December 31, 2019 and 2018, the Company had no loans that were past due in regards to principal and/or interest payments. Additionally, the Company held no loans that were on nonaccrual status or considered impaired as of December 31, 2019 and 2018. The Company had no troubled debt restructurings during the years ended December 31, 2019 and 2018.

Credit Quality Indicators

The key credit quality indicators used by the Company in establishing the general and specific loan loss reserves, as well as in determining whether or not a loan should be impaired, include loan-to-value and debt service coverage ratios for CMLs and TREs and ratings for its middle market loan portfolio. Given that transitional real estate loans involve properties undergoing renovation or construction, loan-to-value provides the most insight on the credit risk of the property. Middle market loans generally have below-investment-grade ratings. The performance of the loans are monitored and reviewed periodically, but not less than quarterly.

The table below summarizes key credit quality information by carrying value for CMLs and TREs as of December 31.

For those VIEs other than certain unit trust structures, the Company's involvement is passive in nature. The Company has not, nor has it been, required to purchase any securities issued in the future by these VIEs.


The Company's ownership interest in VIEs is limited to holding the obligations issued by them. The Company has no direct or contingent obligations to fund the limited activities of these VIEs, nor does it have any direct or indirect financial guarantees related to the limited activities of these VIEs. The Company has not provided any assistance or any other type of financing support to any of the VIEs it invests in, nor does it have any intention to do so in the future. For those VIEs in

(1) Consists entirely of alternative investments in limited partnerships


The Company holds alternative investments in limited partnerships that have been determined to be VIEs. These partnerships invest in private equity and structured investments. The Company’s maximum exposure to loss on these investments is limited to the amount of its investment. The Company is not the primary beneficiary of these VIEs and is therefore not required to consolidate them. The Company classifies these investments as Other investments in the consolidated balance sheets.


Certain investments in VIEs that the Company is not required to consolidate are investments that are in the form of debt obligations from the VIEs that are irrevocably and unconditionally guaranteed by their corporate parents or sponsors. These VIEs are the primary financing vehicles used by their corporate sponsors to raise financing in the capital markets. The variable interests created by these VIEs are principally or solely a result of the debt instruments issued by them. The Company does not have the power to direct the activities that most significantly impact the entity's economic performance, nor does it have the obligation to absorb losses of the entity or the right to receive benefits from the entity. As such, the Company is not the primary beneficiary of these VIEs and is therefore not required to consolidate them.


Securities Lending and Pledged Securities


The Company lends fixed-maturityfixed maturity and public equity securities to financial institutions in short-term security-lending transactions. These short-term security-lending arrangements increase investment income with minimal risk. The Company receives cash or other securities as collateral for such loans. The Company's security lending policy requires that the fair value of the securities and/or unrestricted cash received as collateral be 102% or more of the fair value of the loaned securities and that unrestricted cash received as collateral be 100% or more of the fair value of the loaned securities. TheseThe securities loaned continue to be carried as investment assets on the Company's balance sheet during the terms of the loans and are not reported as sales. The Company receives cash or other securities as collateral for such loans. For loans involving unrestricted cash or securities as collateral, the collateral is reported as an asset with a corresponding liability for the return of the collateral. For loans where the Company receives as collateral securities that the Company is not permitted to sell or repledge, the collateral is not reflected on the consolidated financial statements.

4.  DERIVATIVE INSTRUMENTS
The Company's freestanding derivative financial instruments have historically consisted of: (1)
foreign currency forwards and options used in hedging foreign exchange risk on U.S. dollar-denominated investments in Aflac Japan's portfolio; (2) portfolio

foreign currency forwards and options used to hedge foreign exchange risk from the Company's net investment in Aflac Japan and economically hedge certain portions of forecasted cash flows denominated in yen; (3) swaps associated withyen and hedge the Company's notes payable, consisting of long term exposure to a weakening yen

cross-currency interest rate swaps, also referred to as foreign currency swaps, associated with certain senior notes and its subordinated debentures; (4) debentures

foreign currency swaps and, in prior periods, credit default swaps that are associated with investments in special-purpose entities, including VIEs where the Company is the primary beneficiary; and (5) options on beneficiary

interest rate swaps (orused to economically hedge interest rate swaptions) and futuresfluctuations in certain variable-rate investments

interest rate swaptions used to hedge changes in the fair value associated with interest rate riskfluctuations for certain U.S. dollar-denominated available-for-sale fixed-maturity securities. The Company does not use derivative financial instruments for trading purposes, nor does it engage in leveraged derivative transactions.

Some of the Company's derivatives are designated as cash flow hedges, fair value hedges or net investment hedges; however, other derivatives do not qualify for hedge accounting or the Company elects not to designate them as an accounting hedge. The Company utilizes a net investment hedge to mitigate foreign exchange exposure resulting from its net investment in Aflac Japan. In addition to designating derivatives as hedging instruments, the Company has designated the majority of the Parent Company's yen-denominated liabilities (notes payable and loans) as nonderivative hedging instruments for this net investment hedge.hedges.


Derivative Types


Foreign currency forwards and options are executed for the Aflac Japan segment in order to hedge the currency risk on the carrying value of certain U.S. dollar-denominated investments. The average maturity of these forwards and options can change depending on factors such as market conditions and types of investments being held. In situations where the maturity of the forwards and options areis shorter than the underlying investment being hedged, the Company may enter into new forwards and options near maturity of the existing derivative in order to continue hedging the underlying investment.

The Company enters into foreign currency swaps pursuant to which it exchanges an initial principal amount in one currency for an initial principal amount of another currency, with an agreement to re-exchange the currenciesprincipal amounts at a future date at an agreed upon exchange rate.date. There may also be periodic exchanges of payments at specified intervals based on the agreed upon rates and notional amounts. Foreign currency swaps are used primarily in the consolidated VIEs in the Company's Aflac Japan portfolio to convert foreign-denominated cash flows to yen, the functional currency of Aflac Japan, in order to minimize cash flow fluctuations. The Company also uses foreign currency swaps to economically convert certain of its U.S. dollar-denominated senior note and subordinated debenture principal and interest obligations into yen-denominated obligations.


The only CDS thatIn order to reduce investment income volatility from its variable-rate investments, the Company currently hold relates to components of an investment in a VIE and is used to assume credit risk related to an individual security. This CDS contract entitles the consolidated VIE to receive periodic fees in exchange for an obligation to compensate the derivative counterparties should the referenced security issuer experience a credit event, as defined in the contract.

Interestenters into receive–fixed, pay–floating interest rate swaps involve the periodic exchange of cash flows with other parties, at specified intervals, calculated using agreed upon rates or other financial variables and notional principal amounts. Typically, at the time a swap is entered into, the cash flow streams exchanged by the counterparties are equal in value. No cash or principal payments are exchanged at the inception of the contract. Interest rate swaps are primarily used to convert interest receipts on floating-rate fixed-maturity securities contracts to fixed rates.swaps.

Item 8. Financial Statements and Supplementary Data


Beginning in July 2019, certain foreign currency forwards and options have beenwere designated as derivative hedges of the foreign currency exposure of the Company's net investment in Aflac Japan. Prior to April 1, 2018, foreign currency forwards and options were also designated as derivative hedges of the foreign currency exposure of the Company's net investment in Aflac Japan.

The Company used foreign exchange forwards and options to hedge foreign exchange risk on 90.9 billion yen of profit repatriation received from Aflac Japan in 2017. As of December 31, 2017, the Company had entered into foreign exchange forwards and options as part of a hedge on 49.5 billion yen of future profit repatriation.


The Company's net investment hedge was effective forduring the years ended December 31, 2017, 20162019, 2018 and 2015.2017.
Non-qualifying Strategies
For the Company's derivative instruments in consolidated VIEs that do not qualify for hedge accounting treatment, all changes in their fair value are reported in current period earnings within derivative and otherrealized investment gains (losses). The amount of gain or loss recognized in earnings for the Company's VIEs is attributable to the derivatives in those investment structures. While the change in value of the swaps is recorded through current period earnings, the change in value of the available-for-sale fixed-maturity or perpetualfixed maturity securities associated with these swaps is recorded through other comprehensive income.
As of December 31, 2017,2019, the Parent Company had cross-currency interest rate swap agreements related to its $550 million senior notes due March 2020, $350 million senior notes due February 2022, $700 million senior notes due June 2023, $750 million senior notes due November 2024 and $450 million senior notes due March 2025. Changes in the values of these swaps are recorded through current period earnings. For additional information regarding these swaps, see Note 9.

This activity is reported in the Corporate and other segment. As of July 1, 2019, the Parent Company designates these foreign exchange forward contracts as accounting hedges of its net investment in Aflac Japan.

The Company uses interest rate swaps to economically convert the variable rate investment income to a fixed rate on certain variable-rate investments.

The Company is a direct counterparty to the foreign currency swaps that it has entered into in connection with certain of its senior notes and subordinated debentures; foreign currency forwards; and foreign currency options; and interest rate swaptions,options, and therefore the Company is exposed to credit risk in the event of nonperformance by the counterparties in those contracts. The risk of counterparty default for the Company's foreign currency swaps, certain foreign currency

121



forwards, and foreign currency options and interest rate swaptions is mitigated by collateral posting requirements that counterparties to those transactions must meet.


As of December 31, 2017, there were 15 counterparties to2019, all of the Company's derivative agreements, with four comprising 60% of the aggregate notional amount. Theagreement counterparties to these derivatives are financial institutions with the following credit ratings as of December 31:were investment grade.

The Company engages in over-the-counter (OTC) bilateral derivative transactions directly with unaffiliated third parties under International Swaps and Derivatives Association, Inc. (ISDA) agreements and other documentation. Most of the ISDA agreements also include Credit Support Annexes (CSAs) provisions, which generally provide for two-way collateral postings at the first dollar of exposure. The Company mitigates the risk that counterparties to transactions might be unable to fulfill their contractual obligations by monitoring counterparty credit exposure and collateral value while generally requiring that collateral be posted at the outset of the transaction. In addition, a significant portion of the derivative transactions have provisions that give the counterparty the right to terminate the transaction upon a downgrade of Aflac’s financial strength rating. The actual amount of payments that the Company could be required to make depends on market conditions, the fair value of outstanding affected transactions, and other factors prevailing at and after the time of the downgrade.


The Company also engages in OTC cleared derivative transactions through regulated central clearing counterparties. These positions are marked to market and margined on a daily basis (both initial margin and variation margin), and the Company has minimal exposure to credit-related losses in the event of nonperformance by counterparties to these derivatives.

Collateral posted by the Company to third parties for derivative transactions can generally be repledged or resold by the counterparties. The aggregate fair value of all derivative instruments with credit-risk-related contingent features that were in a net liability position by counterparty was approximately $264$301 million and $1.2 billion$139 million as of December 31, 20172019 and 2016,2018, respectively. If the credit-risk-related contingent features underlying these agreements had been triggered on December 31, 2017,2019, the Company estimates that it would be required to post a maximum of $9$46 million of additional collateral to these derivative counterparties. The Company is generally allowed to sell or repledge collateral obtained from its derivative counterparties, although it does not typically exercise such rights. (See the Offsetting tables below for collateral posted or received as of the reported balance sheet dates.)


Offsetting of Financial Instruments and Derivatives


Most of the Company's derivative instruments are subject to enforceable master netting arrangements that provide for the net settlement of all derivative contracts between the Parent Company or Aflacits subsidiaries and itsthe respective counterparty in the event of default or upon the occurrence of certain termination events. Collateral support agreements with the master netting arrangements generally provide that the Company will receive or pledge financial collateral at the first dollar of exposure.


The Company has securities lending agreements with unaffiliated financial institutions that post collateral to the Company in return for the use of its fixed maturity and public equity securities (see Note 3). When the Company has entered into securities lending agreements with the same counterparty, the agreements generally provide for net settlement in the event of default by the counterparty. This right of set-off allows the Company to keep and apply collateral received if the counterparty failed to return the securities borrowed from the Company as contractually agreed. For additional information on the Company's accounting policy for securities lending, see Note 1.


The tables below summarize the Company's derivatives and securities lending transactions as of December 31, and as reflected in the tables, in accordance with U.S. GAAP, the Company's policy is to not offset these financial instruments in the Consolidated Balance Sheets.

5.FAIR VALUE MEASUREMENTS
Fair Value Hierarchy


U.S. GAAP specifies a hierarchy of valuation techniques based on whether the inputs to those valuation techniques are observable or unobservable. These two types of inputs create three valuation hierarchy levels. Level 1 valuations reflect quoted market prices for identical assets or liabilities in active markets. Level 2 valuations reflect quoted market prices for similar assets or liabilities in an active market, quoted market prices for identical or similar assets or liabilities in non-active markets or model-derived valuations in which all significant valuation inputs are observable in active markets. Level 3 valuations reflect valuations in which one or more of the significant inputs are not observable in an active market.


The following tables present the fair value hierarchy levels of the Company's assets and liabilities that are measured and carried at fair value on a recurring basis as of December 31.

Fair Value of Financial Instruments


Fixed maturities, perpetual securities,maturity and equity securities


The Company determines the fair values of fixed-maturity securities, perpetualfixed maturity securities and public and privately issuedprivately-issued equity securities using the following approaches or techniques: price quotes and valuations from third party pricing vendors (including quoted market prices readily available from public exchange markets) and non-binding price quotes the Company obtains from outside brokers.


A third party pricing vendor has developed valuation models to determine fair values of privately issued securities to reflect the impact of the persistent economic environment and the changing regulatory framework. These models are discounted cash flow (DCF) valuation models, but also use information from related markets, specifically the CDS market to estimate expected cash flows. These models take into consideration any unique characteristics of the securities and make various adjustments to arrive at an appropriate issuer-specific loss adjusted credit curve. This credit curve is then used with the relevant recovery rates to estimate expected cash flows and modeling of additional features, including illiquidity adjustments, if necessary, to price the security by discounting those loss adjusted cash flows. In cases where a credit curve cannot be developed from the specific security features, the valuation methodology takes into consideration other market observable inputs, including:
1) the most appropriate comparable security(ies) of the issuer; issuer
2) issuer-specific CDS spreads; spreads
3) bonds or CDS spreads of comparable issuers with similar characteristics such as rating, geography, or sector; or sector
4) bond indices that are comparative in rating, industry, maturity and region.


The pricing data and market quotes the Company obtains from outside sources, including third party pricing services, are reviewed internally for reasonableness. If a fair value appears unreasonable, the Company will re-examine the inputs and assess the reasonableness of the pricing data with the vendor. Additionally, the Company may compare the inputs to

132


Item 8. Financial Statements and Supplementary Data


relevant market indices and other performance measurements. Based on management's analysis, the valuation is confirmed or may be revised if there is evidence of a more appropriate estimate of fair value based on available market data. The Company has performed verification of the inputs and calculations in any valuation models to confirm that the valuations represent reasonable estimates of fair value.


128




The fixed maturitiesmaturity securities classified as Level 3 consist of securities with limited or no observable valuation inputs. For Level 3 securities, the Company estimates the fair value of these securities by obtaining non-binding broker quotes from a limited number of brokers. These brokers base their quotes on a combination of their knowledge of the current pricing environment and market conditions. The Company considers these inputs to be unobservable. The Company also considers a variety of significant valuation inputs in the valuation process, including forward exchange rates, yen swap rates, dollar swap rates, interest rate volatilities, credit spread data on specific issuers, assumed default and default recovery rates, and certain probability assumptions. In obtaining these valuation inputs, the Company has determined that certain pricing assumptions and data used by its pricing sources are difficult to validate or corroborate by the market and/or appear to be internally developed rather than observed in or corroborated by the market. The use of these unobservable valuation inputs causes more subjectivity in the valuation process for these securities.


For the periods presented, the Company has not adjusted the quotes or prices it obtains from the pricing services and brokers it uses.


The following tables present the pricing sources for the fair values of the Company's fixed maturities, perpetual securities,maturity and equity securities as of December 31.

The following is a discussion of the determination of fair value of the Company's remaining financial instruments.


Derivatives


The Company uses derivative instruments to manage the risk associated with certain assets. However, the derivative instrument may not be classified in the same fair value hierarchy level as the associated asset. The Company uses pricing models to determine the estimated fair value of derivatives. Inputs used to value derivatives include, but are not limited to, interest rates, credit spreads, foreign currency forward and spot rates, and interest volatility. The significant inputs to pricing derivatives are generally observable in the market or can be derived by observable market data. When these inputs are observable, the derivatives are classified as Level 2.


The fair values of the foreign currency forwards options, and interest rate swaptions associated with certain investments; the foreign currency forwards and options used to hedge foreign exchange risk from the Company's net investment in Aflac Japan and economically hedge certain portions of forecasted cash flows denominated in yen; and the foreign currency swaps associated with certain senior notes and subordinated debentures are based on the amounts the Company would expect to receive or pay. The determination of the fair value of these derivatives is based on observable market inputs, therefore they are classified as Level 2.


To determine the fair value of its interest rate derivatives, the Company uses inputs that are generally observable in the market or can be derived from observable market data. Interest rate swaps are cleared trades. In a cleared swap contract the clearinghouse provides benefits to the counterparties similar to contracts listed for investment traded on an exchange since it maintains a daily margin to mitigate counterparties credit risk. These derivatives are priced using observable inputs, accordingly, they are classified as Level 2. For its interest rate swaptions, the Company estimates their fair values using observable market data, including interest rate curves and volatilities. Their fair values are also classified as Level 2.
For derivatives associated with VIEs where the Company is the primary beneficiary, the Company is not the direct counterparty to the swap contracts. As a result, the fair value measurements incorporate the credit risk of the collateral associated with the VIE. The Company receives valuations from a third party pricing vendor for these derivatives. Based on

137


Item 8. Financial Statements and Supplementary Data


an analysis of these derivatives and a review of the methodology employed by the pricing vendor, the Company determined that due to the long duration of these swaps and the need to extrapolate from short-term observable data to derive and measure long-term inputs, certain inputs, assumptions and judgments are required to value future cash flows

133



that cannot be corroborated by current inputs or current observable market data. As a result, the derivatives associated with the Company's consolidated VIEs are classified as Level 3 of the fair value hierarchy.


Other investmentsCommercial mortgage and other loans


Other investments where fair value is disclosed above include short-term investmentsCommercial mortgage and loan receivables. Loan receivablesother loans include transitional real estate loans, commercial mortgage loans and middle market loans. The Company's loan receivables do not have readily determinable market prices and generally lack market liquidity. Fair values for loan receivables are determined based on the present value of expected future cash flows discounted at the applicable U.S. Treasury or London Interbank Offered Rate (LIBOR) yield plus an appropriate spread that considers other risk factors, such as credit and liquidity risk. These spreads are provided by the applicable asset managers based on their knowledge of the current loan pricing environment and market conditions. The spreads are a significant component of the pricing inputs and are generally considered unobservable. Therefore, these investments have been assigned a Level 3 within the fair value hierarchy.


Other investments

Other investments includes short-term investments that are measured at fair value where amortized cost approximates fair value.

Other policyholders' funds


The largest component of the other policyholders' funds liability is the Company's annuity line of business in Aflac Japan. The Company's annuities have fixed benefits and premiums. For this product, the Company estimates the fair value to be equal to the cash surrender value. This is analogous to the value paid to policyholders on the valuation date if they were to surrender their policy. The Company periodically checks the cash value against discounted cash flow projections for reasonableness. The Company considers its inputs for this valuation to be unobservable and have accordingly classified this valuation as Level 3.


Notes payable


As of December 31, 2016, theThe fair values of the Company's publicly issued notes payable were obtained from a limited number of independent brokers and classified as Level 3 within the fair value hierarchy. However, in 2017 recognizing the similarities of the Company'spublicly issued notes payable to fixed income securities in its investment portfolios, the Company aligned the determination of the fair values of these liabilities with its practices of determining asset fair values whereby the Company utilizesare determined by utilizing available sources of observable inputs from third party pricing vendors; therefore, the fair values of the Company's publicly issued notes payable were reclassified intovendors and are classified as Level 2 from Level 3 in the first quarter of 2017.2. The fair values of the Company's yen-denominated loans approximate their carrying values.values and are classified as Level 3.



Transfers between Hierarchy Levels and Level 3 Rollforward


There were no transfers between Level 1 and 2 for assets and liabilities that are measured and carried at fair value on a recurring basis for the years ended December 31, 20172019 and 2016,2018, respectively.


The following tables present the changes in fair value of the Company's available-for-sale investments and derivatives carried at fair value classified as Level 3 as of December 31.

Item 8. Financial Statements and Supplementary Data


The following is a discussion of the significant unobservable inputs or valuation techniques used in determining the fair value of securities and derivatives classified as Level 3.


Net Asset Value


The Company holds certain unlisted equity securities whose fair value is derived based on the financial statements published by the investee. These securities do not trade on an active market and the valuations derived are dependent on the availability of timely financial reporting of the investee. Net asset value is an unobservable input in the determination of fair value ofequity securities.


Offered Quotes


In circumstances where the Company's valuation model price is overridden because it implies a value that is not consistent with current market conditions, the Company will solicit bids from a limited number of brokers. The Company also receives unadjusted prices from brokers for its mortgage and asset-backed securities. These quotes are non-binding but are reflective of valuation best estimates at that particular point in time. Offered quotes are an unobservable input in the determination of fair value of mortgage- and asset-backed securities, certain banks/financial institutions, certain other corporate, and equity securities investments.


Interest Rates and CDS Spreads Foreign Exchange Rates


The significant drivers of the valuation of the interest and foreign exchange swaps are interest rates foreign exchange rates and CDS spreads. TheSome of the Company's swaps have long maturities that increase the sensitivity of the swaps to interest rate fluctuations. Since most ofFor the Company's yen-denominatedforeign exchange or cross currency swaps that are in a net liabilityasset position, an increase in yen interest rates (all other factors held constant) will decrease the liabilities and increasepresent value of the yen final settlement receivable (receive leg), thus decreasing the value of the swap.swap as long as the derivative remains in a net asset position.
Foreign exchange swaps also have a lump-sum final settlement of foreign exchange principal receivablesamounts at the termination of the swap. AnAssuming all other factors are held constant, an increase in yen interest rates will decrease the receive leg and decrease the net value of the final settlement foreign exchange receivables and decrease the value of the swap, andswap. Likewise, holding all other factors constant, an increase in U.S. dollar interest rates will increase the swap value.
A similar sensitivity pattern is observed for the foreign exchange rates. When the spot U.S. dollar/Japanese yen (USD/JPY) foreign exchange rate decreases and the swap is receiving a final exchange payment in JPY, the swapswap's net value will increase due to the appreciation of the JPY. Most of the Company's swaps are designed to receive payments in JPY at the termination and will thus be impacted by the USD/JPY foreign exchange rate in this way. In cases where there is no final foreign exchange receivable in JPY and the Company is paying JPY as interest payments and receiving USD, a decrease in the foreign exchange rate will lead to a decrease inpresent value of the swap value.

dollar final settlement payable (pay leg).
The extinguisher feature in most of the Company's VIE swaps results in a cessation of cash flows and no further payments between the parties to the swap in the event of a default on the referenced or underlying collateral. To price this feature, the Company applies the survival probability of the referenced entity to the projected cash flows. The survival probability uses the CDS spreads and recovery rates to adjust the present value of the cash flows. For extinguisher swaps with positive values, an increase in CDS spreads decreases the likelihood of receiving the final exchange payments and reduces the value of the swap.

Base Correlations, CDS Spreads, Recovery Rates

The Company's remaining collateralized debt obligation (CDO) is a tranche on a basket of single-name credit default swaps. The risk in this synthetic CDO comes from the single-name CDS risk and the correlations between the single names. The valuation of synthetic CDOs is dependent on the calibration of market prices for interest rates, single name CDS default probabilities and base correlation using financial modeling tools. Since there is limited or no observable data available for this tranche, the base correlations must be obtained from commonly traded market tranches such as the CDX and iTraxx indices. From the historical prices of these indices, base correlations can be obtained to develop a pricing curve of CDOs with different seniorities. Since the reference entities of the market indices do not match those in the portfolio underlying the synthetic CDO to be valued, several processing steps are taken to map the CDO in the Company's portfolio to the indices. With the base correlation determined and the appropriate spreads selected, a valuation is calculated. An increase in the CDS spreads in the underlying portfolio leads to a decrease in the value due to higher probability of defaults and losses. The impact on the valuation due to base correlation depends on a number of factors, including the riskiness between market tranches and the modeled tranche based on the Company's portfolio and the equivalence between detachment points in these tranches. Generally speaking, an increase in base correlation will

decrease the value of the senior tranches while increasing the value of junior tranches. This may result in a positive or negative value change.

The CDO tranche in the Company's portfolio is a senior mezzanine tranche and, due to the low level of credit support for this type of tranche, exhibits equity-like behavior. As a result, an increase in recovery rates tends to cause its value to decrease.

Base correlations, CDS spreads, and recovery rates are unobservable inputs in the determination of fair value of credit default swaps.

The favorable claims development of $518$552 million for 20172019 comprises approximately $383$395 million from Japan, which represents approximately 74%72% of the total. Excluding the impact of foreign exchange of a lossgain of approximately $18$5 million from December 31, 20162018 to December 31, 2017,2019, the favorable claims development in Japan would have been approximately $400$390 million, representing approximately 77%71% of the total.


The Company has experienced continued favorable claim trends in 20172019 for its core health products in Japan. The Company's experience in Japan related to the average length of stay in the hospital for cancer treatment has shown continued decline in the current period. In addition, cancer treatment patterns in Japan are continuing to be influenced by significant advances in early-detection techniques and by the increased use of pathological diagnosis rather than clinical exams. Additionally, follow-up radiation and chemotherapy treatments are occurring more often on an outpatient basis. Such changes in treatment not only increase the quality of life and initial outcomes for the patients, but also decrease the average length of each hospital stay, resulting in favorable claims development.


As of December 31, 20172019 and 2016,2018, unearned premiums consisted primarily of discounted advance premiums on deposit. Discounted advance premiums are premiums on deposit from policyholders in conjunction with their purchase of certain Aflac Japan limited-pay insurance products. These advanced premiums are deferred upon collection and recognized as premium revenue over the contractual premium payment period. These advanced premiums represented 73%64% of the December 31, 20172019 and 76%69% of the December 31, 20162018 unearned premiums balances.


As of December 31, 20172019 and 2016,2018, the largest component of the other policyholders' funds liability was the Company's annuity line of business in Aflac Japan.

8. REINSURANCE


The Company periodically enters into fixed quota-share coinsurance agreements with other companies in the normal course of business. For each of its reinsurance agreements, the Company determines whether the agreement provides indemnification against loss or liability relating to insurance risk in accordance with applicable accounting standards. Reinsurance premiums and benefits paid or provided are accounted for on bases consistent with those used in accounting for the original policies issued and the terms of the reinsurance contracts. Premiums and benefits are reported net of insurance ceded.


Effective March 31, 2015, the Company entered into a coinsurance transaction whereby it ceded 30.0% of the sickness hospital benefit of one of Aflac Japan’s closed in-force blocks of business. The Company has an agreement for a $90 million letter of credit as collateral for this reinsurance transaction (see Note 13 for additional information). Effective April 1, 2015, the Company entered into a retrocession coinsurance transaction whereby it assumed 27.0% of the sickness hospital benefit of one of Aflac Japan’s closed in-force blocks of business through its subsidiary CAIC.

Effective October 1, 2014 and September 30, 2013, the Company entered into coinsurance reinsurance transactions whereby it ceded 16.7% and 33.3%, respectively, of the hospital benefit of one of Aflac Japan’s closed medical in-force blocks of business. Effective December 31, 2014, the Company entered into a retrocession coinsurance reinsurance transaction whereby it assumed 8.35% of the reinsured hospital benefit of one of Aflac Japan’s closed medical in-force blocks of business through its subsidiary CAIC.

For its reinsurance transactions to date, the Company has recorded a deferred profit liability related to reinsurance transactions. The remaining deferred profit liability of $954 million,$1.0 billion, as of December 31, 2017,2019, is included in future policy benefits in the consolidated balance sheet and is being amortized into income over the expected lives of the policies. The Company has also recorded a reinsurance recoverable for reinsurance transactions, which is included in other assets in the consolidated balance sheet and had a remaining balance of $908$970 million and $860$941 million as of December 31, 20172019 and 2016,2018, respectively. The increase in the reinsurance recoverable balance was driven by two aggregating factors: yen strengthening and the growth in reserves related to the business that has been reinsured as the policies age. The spot yen/dollar exchange rate strengthened by approximately 3%1.3% and ceded reserves increased approximately 2%1.4% from December 31, 2016,2018, to December 31, 2017.2019.

These reinsurance transactions are indemnity reinsurance that do not relieve the Company from its obligations to policyholders. In the event that the reinsurer is unable to meet their obligations, the Company remains liable for the reinsured claims.


As a part of its capital contingency plan, the Company entered into a committed reinsurance facility agreement on December 1, 2015 in the amount of approximately 110¥110 billion yen.of reserves. This reinsurance facility agreement was renewed in 20172019 and is effective until December 31, 2018.2020. There are also additional commitment periods of a one-year duration each of which are automatically extended unless notification is received from the reinsurer within 60 days prior to the expiration.

These notes are redeemable at the Parent Company's option in whole at any time or in part from time to time at a redemption price equal to the greater of: (i) the aggregate principal amount of the notes to be redeemed or (ii) the amount equal to the sum of the present values of the remaining scheduled payments for principal of and interest on the notes to be redeemed, not including any portion of the payments of interest accrued as of such redemption date, discounted to such redemption date on a semiannual basis at the treasury rate plus 20 basis points, plus in each case, accrued and unpaid interest on the principal amount of the notes to be redeemed to, but excluding, such redemption date. The Parent Company had entered into cross-currency interest rate swaps to reduce interest expense by converting the U.S. dollar-denominated principal and interest on the senior notes it issued into yen-denominated obligations. By entering into these swaps, the Parent Company economically converted its $700 million liability into a 69.8¥69.8 billion yen liability and reduced the interest rate on this debt from 3.625% in dollars to 1.50% in yen.

In September 2012, the Parent Company issued $450 million of subordinated debentures through a U.S. public debt offering. The debentures bore interest at a fixed rate of 5.50% per annum, payable quarterly, and had a 40-year maturity. The Parent Company had entered into cross-currency interest rate swaps to convert the U.S. dollar-denominated principal and interest on the subordinated debentures it issued into yen-denominated obligations. By entering into these swaps, the Parent Company economically converted its $450 million liability into a 35.3 billion yen liability and reduced the interest rate on this debt from 5.50% in dollars to 4.41% in yen. The swaps expired after the initial five-year non-callable period for the debentures. In October 2012, the underwriters exercised their option, pursuant to the underwriting agreement, to purchase an additional $50 million principal amount of the debentures discussed above. The Parent Company had entered into a cross-currency interest rate swap to economically convert this $50 million liability into a 3.9 billion yen liability and reduce the interest rate from 5.50% in dollars to 4.42% in yen. The swap expired after the initial five-year non-

callable period for the debentures. In November 2017, the Parent Company used a portion of net proceeds from the October 2017 issuance of its subordinated debentures to redeem $500 million of the Parent Company's 5.50% subordinated debentures due 2052. The pretax expense due to the early redemption of these notes was $13 million.


In February 2012, the Parent Company issued two series$350 million of senior notes totaling $750 million through a U.S. public debt offering. The first series, which totaled $400 million, bears interest at a fixed rate of 2.65% per annum, payable semiannually, and had a five-year maturity. The second series, which totaled $350 million, bearsnotes bear interest at a fixed rate of 4.00% per annum, payable semiannually, and has a 10-year maturity.will mature in February 2022. These notes are redeemable at the Parent Company's option in whole at any time or in part from time to time at a redemption price equal to the greater of: (i) the principal amount of the notes or (ii) the present value of the remaining scheduled payments of principal and interest to be redeemed, discounted to the redemption date, plus accrued and unpaid interest. The Parent Company entered into cross-currency interest rate swaps to reduce interest expense by converting the U.S. dollar-denominated principal and interest on the senior notes it issued into yen-denominated obligations. By entering into these swaps, the Parent Company economically converted its $400 million liability into a 30.9 billion yen liability and reduced the interest rate on this debt from 2.65% in dollars to 1.22% in yen. The Parent Company also economically converted its $350 million liability into a 27.0¥27.0 billion yen liability and reduced the interest rate on this debt from 4.00% in dollars to 2.07% in yen. In July 2012, the Parent Company issued $250 million of senior notes that are an addition to the original first series of senior notes issued in February 2012. These notes had a five-year maturity and a fixed rate of 2.65% per annum, payable semiannually. In February 2017, the Parent Company extinguished $650 million of the 2.65% senior notes upon their maturity.


In 2010 and 2009, the Parent Company issued senior notes through U.S. public debt offerings; the details of these notes are as follows. In August 2010, the Parent Company issued $450 million of senior notes that have a 30-year maturity.will mature in August 2040. In December 2009, the Parent Company issued $400 million of senior notes that have a 30-year maturity.will mature in December 2039. These senior notes pay interest semiannually and are redeemable at the Parent Company's option in whole at any time or in part from time to time at a redemption price equal to the greater of: (i) the principal amount of the notes or (ii) the present value of the remaining scheduled payments of principal and interest to be redeemed, discounted to the redemption date, plus accrued and unpaid interest. In December 2016, the Parent Company completed a tender offer in which it extinguished $176 million principal of its 6.90% senior notes due December 2039 and $193 million principal of its 6.45% senior notes due August 2040. The pretax loss due to the early redemption of these notes was $137 million.


For the Company's yen-denominated notes and loans, the principal amount as stated in dollar terms will fluctuate from period to period due to changes in the yen/dollar exchange rate. The Company has designated the majority of its yen-denominated notes payable as a nonderivative hedge of the foreign currency exposure of the Company's investment in Aflac Japan.

The Japan income tax rate for the fiscal year 20152017 was 30.8%28.2%. The rate was reduced to 28.8%28.0% for the fiscal year 2016years 2018 and 28.2% for the fiscal year 2017.2019.


For the United States,U.S., the Tax Cuts and Jobs Act (Tax Act) was signed into law on December 22, 2017. Effective January 1, 2018, the Tax Act imposesimposed a broad number of changes in tax law, including the permanent reduction ofpermanently reducing the U.S. federal statutory corporate income tax rate from 35% to 21%., eliminating or reducing certain deductions and credits and limiting the deductibility of interest expense and executive compensation.
At December 22, 2017, prior to accounting for the effects of the Tax Act, the Company calculated a reasonable estimate of its deferred tax assets (DTA) to equal $6.2 billion and deferred tax liabilities (DTL) to equal $12.7 billion, resulting in a net deferred tax liability of $6.5 billion. Based on the value of its deferred assets and liabilities as of the December 22, 2017, enactment date, the Company has evaluated the effects of the Tax Act and has concluded that the reduction in the U.S. federal statutory corporate income tax rate from 35% to 21% will necessitate revaluation of its deferred tax assets and liabilities.
The Company expects to complete its accounting for the effects of the Tax Act over the measurement period of up to one year from the enactment date, as permitted by SECIn accordance with Staff Accounting Bulletin No. 118 (SAB 118). issued by the U.S. Securities and Exchange Commission in December 2017, the Company recorded provisional amounts for certain items for which the income tax accounting was not complete. As of the enactment date, the Company has determined a reasonable estimate of income tax effects of the Tax Act. The Company’s current estimated provisional amounts for its deferred taxes, including related valuation allowance, resultresulting in a reduction of its DTADTAs by approximately $1.0 billion and its DTLdeferred tax liabilities (DTLs) by $2.9 billion, for a net DTL reduction of approximately $1.9 billion. The Company believes that these amounts represent reasonable estimates in accordance with SAB 118. The provisions of ASC 740-10,Income Taxes, require that the effects of changes in tax law on deferred taxes be recognized as a component of the income tax provision in the period the tax rate change was enacted. Therefore, the $1.9 billion provisional amount of net DTL reduction has beenwas recorded in the fourth quarter of 2017 as a reduction in the “Income tax expense, Deferred” line item of the Company’s consolidated statement of earnings.
The following includes an overview of
In 2018, the existing current and deferred balances for which calculation ofCompany recorded additional income tax effectsexpense of $.4 million resulting from a decrease in the SAB 118 provisional estimate related to Japan deferred tax balances. No further adjustment was made to the SAB 118 provisional estimate related to the valuation allowance. As of December 31, 2018, the Company has completed its accounting for the Tax Act has not been completed:in accordance with SAB 118.
Japan deferred tax balances: The Tax Act reduces the tax rate to 21%, effective January 1, 2018. Prior to the reduction in rate, the Japan deferred tax balances were completely offset by an anticipatory foreign tax credit. As a result of the rate reduction, the Japan deferred tax balance will no longer be offset by an anticipatory foreign tax credit as all of the foreign tax credits will be used to offset the U.S. deferred tax balance of the Aflac Japan branch.

The Company has not yet completed its analysis of the components of the Japan tax computation, including a complete validation of the Aflac Japan tax basis. Additional time is needed to collect, analyze, and validate the detailed data underlying the deferred tax amounts in the Aflac Japan branch. The Company has currently recorded a provisional amount of $4.5 billion of net DTL related to this item.



150



Valuation allowances: The Company must assess whether its valuation allowance analyses are impacted by various aspects of the Tax Act with a primary focus on any unused anticipatory foreign tax credits. As the Company has recorded provisional amounts related to the Japan deferred tax balances, any corresponding determination of the need for or change in a valuation allowance is also provisional. The Company has recorded a provisional valuation allowance of $.7 billion against its anticipatory foreign tax credit asset.

The impact of the Tax Act may differ, possibly materially, from the recorded provisional amounts.

As noted above, the provisions of ASC 740-10, Income Taxes, require that the effects of changes in tax law on deferred taxes be recognized as a component of the income tax provision in the period the tax rate change was enacted, even if the deferred taxes are related to items recorded in accumulated other comprehensive income (AOCI). This results in the misalignment between deferred taxes (reflected, net of allowance, at the newly enacted income tax rates) and the corresponding effects of the deferred amounts in AOCI, which are not subject to revaluation as of the enactment date. Therefore, the deferred tax amounts recorded through AOCI and existing at the enactment date of the Tax Act continue to be reflected at the tax rates effective immediately prior to the enactment date, and the amounts recorded in the period between the enactment date and the end of 2017 are reflected at the new rates pursuant to the Tax Act.

Income tax expense in the accompanying statements of earnings varies from the amount computed by applying the expected U.S. tax rate of 21% in both 2019 and 2018 and 35% in 2017 to pretax earnings.

The application of U.S. GAAP requires the Company to evaluate the recoverability of deferred tax assets and establish a valuation allowance if necessary to reduce the deferred tax asset to an amount that is more likely than not expected to be realized. As noted above, theThe Company has determined a $.7 billion$1,022 million valuation allowance against its anticipatory foreign tax credit is necessary. The anticipatory foreign tax credit represents the foreign tax credit the Company will generate from the reversal of Japan deferred tax liabilities in the future. The increase in the valuation allowance on the anticipatory foreign tax credit is due to an increase Japan's local country deferred tax inventory relative to the deferred tax inventory for Japan's U.S. tax obligation. The Company has also determined a $318 million valuation allowance against its deferred foreign tax credits is necessary. Deferred foreign tax credits are foreign tax credits generated in the current tax year by the Japanese life company, but are unable to be utilized until 2020 due to Japan's current tax year not closing until March 31, 2020. The valuation

allowance on the deferred foreign tax credit has increased due to the utilization of prior year credits as well as the recognition of the current year deferred foreign tax credit. Based upon a review of the Company's anticipated future taxable income, and including all other available evidence, both positive and negative, the Company's management has concluded that, notwithstanding the anticipatory foreign tax credit,items noted above, it is more likely than not that all other deferred tax assets will be realized.

Management believes it has established adequate tax liabilities and final resolution of all open audits is not expected to have a material impact on the Company's consolidated financial statements.


A reconciliation of the beginning and ending amount of unrecognized tax benefits is as follows for the years ended December 31:

(In millions) 2019  2018

Balance, end of year $14

 $294


Included in the balance of the liability for unrecognized tax benefits at December 31, 2017,2019, are $13$15 million of tax positions for which the ultimate deductibility is highly certain, but for which there is uncertainty about the timing of such deductibility, compared with $293$14 million at December 31, 2016.2018. Because of the impact of deferred tax accounting, other than interest and penalties, the disallowance of the shorter deductibility period would not affect the annual effective tax rate, but would accelerate the payment of cash to the taxing authority to an earlier period. The Company has accrued approximately $1$2 million as of December 31, 2017,2019, for permanent uncertainties, which if reversed would not have a material effect on the annual effective rate.


The Company recognizes accrued interest and penalties related to unrecognized tax benefits in income tax expense. The Company recognized approximately $1 million in interest and penalties in 2017, compared with $13 million in 20162019, 2018 and $11 million in 2015.2017, respectively. The Company has accrued approximately $2 million for the payment of interest and penalties as of December 31, 2017,2019, compared with $26$2 million a year ago. at December 31, 2018.


As of December 31, 2017,2019, there were no material uncertain tax positions for which the total amounts of unrecognized tax benefits will significantly increase or decrease within the next 12 months.

12. SHARE-BASED COMPENSATION
As of December 31, 2017,2019, the Company has outstanding share-based awards under the Aflac Incorporated Long-Term Incentive Plan (the "Plan")Plan). Share-based awards are designed to reward employees for their long-term contributions to the Company and provide incentives for them to remain with the Company. The number and frequency of share-based awards are based on competitive practices, operating results of the Company, government regulations, and other factors.
The Plan, as amended on February 14, 2017, allows for a maximum number of shares issuable over its term of 37.575 million shares including 1938 million shares that may be awarded in respect of awards other than options or stock appreciation rights. If any awards granted under the Plan are forfeited or are terminated before being exercised or settled for any reason other than tax forfeiture, then the shares underlying the awards will again be available under the Plan.


157




The Plan allows awards to Company employees for incentive stock options (ISOs), non-qualifying stock options (NQSOs), restricted stock, restricted stock units, and stock appreciation rights. Non-employee directors are eligible for grants of NQSOs,

Item 8. Financial Statements and Supplementary Data


restricted stock, and stock appreciation rights. As of December 31, 2017,2019, approximately 20.639.3 million shares were available for future grants under this plan. The ISOs and NQSOs have a term of 10 years, and the share-based awards generally vest upon time-based conditions or time and performance-based conditions. Time-based vesting generally occurs after three years. Performance-based vesting conditions generally include the attainment of goals related to Company financial performance. As of December 31, 2017,2019, the only performance-based awards issued and outstanding were restricted stock awards.awards and units.


Stock options and stock appreciation rights granted under the amended Plan have an exercise price of at least the fair market value of the underlying stock on the grant date and have an expiration date no later than 10 years from the grant date. Time-based restricted stock awards, restricted stock units and stock options granted after January 1, 2017 generally vest on a ratable basis over three years, and awards granted prior to the amendment vest on a three-year cliff basis. The Compensation Committee of the Board of Directors has the discretion to determine vesting schedules.


Share-based awards granted to U.S.-based grantees are settled with authorized but unissued Company stock, while those issued to Japan-based grantees are settled with treasury shares.
Summary of Share-Based Compensation Expense

The Company estimates the fair value of each stock option granted using the Black-Scholes-Merton multiple option approach. Expected volatility is based on historical periods generally commensurate with the estimated terms of the options. The Company uses historical data to estimate option exercise and termination patterns within the model. Separate groups of employees that have similar historical exercise patterns are stratified and considered separately for valuation purposes. The expected term of options granted is derived from the output of the Company's option model and represents the weighted-average period of time that options granted are expected to be outstanding. The Company bases the risk-free interest rate on the Treasury note rate with a term comparable to that of the estimated term of the options. There were no options granted in 2019. The weighted-average fair value of options at their grant date was $15.28 per share$8.81 for 2017,2018 compared with $12.70 for 2016 and $9.46$7.64 in 2015.2017.

PerformancePerformance-Based Restricted Stock Awards and Units


Under the Plan, the Company grants selected executive officers performanceperformance-based restricted stock awards (PBRS) each February whose vesting is contingent upon meeting various performance goals. PBRS are generally granted at-the-money and contingently cliff vest over a period of three years, generally subject to continued employment. In February

2017, 2019, the Company granted 253399 thousand performance-based stock awards, which are contingent on the achievement of Companythe Company's financial performance metrics and its market-based conditions. On the date of grant, the Company estimated

Item 8. Financial Statements and Supplementary Data


the fair value of restricted stock awards with market-based conditions using a Monte Carlo simulation model. The model discounts the value of the stock at the assumed vesting date based on a risk-free interest rate. Based on estimates of actual performance versus the vesting thresholds, the calculated fair value percentage payoutpay-out estimate iswill be updated each quarter. Actual performance, including modification for relative total shareholder return, may result in the ultimate award of 0% to 200% percent of the initial number of PBRS issued, with the potential for no award if company performance goals are not achieved during the three-year period. PBRS subject to accelerated vesting at the date of retirement eligibility is recognized over the implicit service period.


The Company also granted selected executive officers performance-based restricted stock units (PSUs) throughout the year whose vesting is contingent upon meeting various performance goals. PSUs are generally granted at-the-money and contingently cliff vest over a period of three years, generally subject to continued employment. In November 2019, the Company granted 46 thousand performance-based stock units, which are contingent on the achievement of certain Company determined metrics. Based on estimates of actual performance versus the vesting thresholds, the calculated fair value percentage pay-out estimate will be updated each quarter. Actual performance may result in the ultimate award of 0% to 200% percent of the initial number of PSUs issued, with the potential for no award if the Company determined metrics are not achieved during the three-year period. PSUs subject to accelerated vesting at the date of retirement eligibility is recognized over the implicit service period.

The Company uses third-party analyses to assist in developing the assumptions used in, as well as calibrating, thea Monte Carlo simulation model. The Company is responsible for determining the assumptions used in estimating the fair value of its share-based payment awards.


Key assumptions used to value PBRS granted during 20172019 follows:

13. STATUTORY ACCOUNTING AND DIVIDEND RESTRICTIONS
The Company's insurance subsidiaries are required to report their results of operations and financial position to state insurance regulatory authorities on the basis of statutory accounting practices prescribed or permitted by such authorities. Statutory accounting practices primarily differ from U.S. GAAP by charging policy acquisition costs to expense as incurred, establishing future policy benefit liabilities using different actuarial assumptions as well as valuing investments and certain assets and accounting for deferred taxes on a different basis.


Aflac the Company's most significant insurance subsidiary, reports statutory financial statements that are prepared on the basis of accounting practices prescribed or permitted by the Nebraska Department of Insurance (NDOI). The NDOI recognizes statutory accounting principles and practices prescribed or permitted by the state of Nebraska for determining and reporting the financial condition and results of operations of an insurance company, and for determining a company's solvency under Nebraska insurance law. TheStatutory Accounting Principles (SAP) as detailed by the National Association of Insurance Commissioners' (NAIC) Accounting Practices and Procedures Manual (SAP) has been adopted by the state of Nebraska as a component of those prescribed or permitted practices. Additionally, the Director of the NDOI has the right to permit other specific practices which deviate from prescribed practices. Prior to the Japan branch conversion on April 1, 2018, Aflac hashad been given explicit permission by the Director of the NDOI for two such permitted practices. These permitted practices, which do not impactOn April 1, 2018, the calculation of net income on a statutory basis or prevent the triggering of a regulatory event in the Company's risk-based capital calculation, are as follows:

Aflac has reported as admitted assets the refundable lease deposits on the leases of commercial office space which house Aflac Japan's sales operations. These lease deposits are unique and part of the ordinary course of doing business in the country of Japan; these assets would be non-admitted under SAP.

AflacCompany entered into a reinsurance agreement effective March 31, 2015 with a then unauthorized reinsurer. The effective dateseries of this agreement predatedtransactions in order to complete the effective date of Nebraska's Amended Credit for Reinsurance statute (44-416) allowing certified reinsurers and also predated the subsequent approvalconversion of the agreement's assuming reinsurerJapan branch into a Japanese insurance corporation. As a result of the conversion, the permitted practices were no longer necessary, therefore they were canceled by the NDOI effective April 2, 2018. Aflac had no permitted practices as a Certified Reinsurer, which occurred on August 30, 2015of December 31, 2019 and December 24, 2015, respectively. Aflac has obtained a permitted practice to recognize this treaty and counterparty as a Certified Reinsurer for the purpose of determining the collateral required to receive reinsurance reserve credit.2018.


A reconciliation of Aflac's capital and surplus between SAPas determined by NAIC basis and practices permitted by theNebraska state basis was $2.1 billion and $2.6 billion as of Nebraska is shown below:
(In millions)2017 2016
Capital and surplus, Nebraska state basis $11,001
   $11,221

Reinsurance - Japan (818)   (764) 
Capital and surplus, NAIC basis $10,140
   $10,417
 
December 31, 2019 and 2018, respectively. As of December 31, 2017,2019, Aflac's capital and surplus significantly exceeded the required company action level capital and surplus of $1.4$.4 billion. As determined on a U.S. statutory accounting basis, Aflac's net income was $864 million in 2019, $1.3 billion in 2018 and $2.6 billion in 2017, $2.8 billion in2016 and $2.3 billion in 2015.2017.


Aflac Japan must report its results of operations and financial position to the Japanese Financial Services Agency (FSA) on a Japanese regulatory accounting basis as prescribed by the FSA. Capital and surplus of theAflac Japan, branch, based on Japanese regulatory accounting practices, was $6.7$7.8 billion at December 31, 2017,2019, compared with $5.6$6.4 billion at December 31, 2016.2018. Japanese regulatory accounting practices differ in many respects from U.S. GAAP. Under Japanese regulatory accounting practices, policy acquisition costs are expensed immediately; policy benefit and claim reserving methods and assumptions are different; premium income is recognized on a cash basis; different consolidation criteria apply to VIEs; reinsurance is recognized on a different basis; and investments can have a separate accounting classification and treatment referred to as policy reserve matching bonds (PRM).


The Parent Company depends on its subsidiaries for cash flow, primarily in the form of dividends and management fees. Consolidated retained earnings in the accompanying financial statements largely represent the undistributed earnings of the Company's insurance subsidiary. Amounts available for dividends, management fees and other payments to the Parent Company by its insurance subsidiarysubsidiaries may fluctuate due to different accounting methods required by regulatory authorities. These payments are also subject to various regulatory restrictions and approvals related to

161



safeguarding the interests of insurance policyholders. The Company's insurance subsidiaryAflac must maintain adequate risk-based capitalRBC for U.S. regulatory authorities, and itsAflac Japan branch must maintain adequate solvency margins for Japanese regulatory authorities. Additionally, the

The maximum amount of dividends that can be paid to the Parent Company by Aflac and CAIC without prior approval of Nebraska's director of insurance is the greater of the net income from operations, which excludes net realized investment gains, for the previous year determined under statutory accounting principles, or 10% of statutory capital and surplus as of the previous year-end. Dividends declared by Aflac during 20182020 in excess of $2.6 billion$864 million would require such approval. Aflac declared dividends of $2.6$1.3 billion during 2017.2019.


AAfter the Japan branch conversion as of April 1, 2018, Aflac Japan is required to meet certain financial criteria as governed by Japanese corporate law in order to provide dividends to the Parent Company. Under these criteria, dividend capacity at Aflac Japan is basically defined as retained earnings excluding capital reserves, which represent equity generated by capital profits that are statutorily required in Japan, less net after-tax unrealized losses on available-for-sale securities based on the previous fiscal year-end. Prior to April 1, 2018, a portion of Aflac Japan earnings, as determined on a Japanese regulatory accounting basis, cancould be repatriatedremitted each year to Aflac U.S. after complying with solvency margin provisions and satisfying various conditions imposed by Japanese regulatory authorities for protecting policyholders. Profit repatriationsremittances to the United States canU.S. could fluctuate due to changes in the amounts of Japanese regulatory earnings. Among other items, factors affecting regulatory

earnings include Japanese regulatory accounting practices and fluctuations in currency translation of Aflac Japan's U.S. dollar-denominated investments and related investment income into yen. Profits repatriatedremitted by Aflac Japan to the Parent Company, after April 1, 2018, and to Aflac U.S., prior to April 1, 2018, were as follows for the years ended December 31:

The Company entered into foreign exchange forwards and options as part of an economic hedge on foreign exchange risk on 90.9 billion yen of profit repatriation received in 2017, resulting in $1 million less funds received when the yen were exchanged into dollars relative to what would have been received at the then-current exchange rate. As of December 31, 2017, the Company had foreign exchange forwards and options as part of a hedging strategy on 49.5 billion yen of future profit repatriation.

(2)For the years 20172019, 20162018 and 20152017, the health care cost trend rates are expected to trend down to 4.5%3.8% in 7754 years, 4.5%4.1% in 7461 years, and 4.5% in 7877 years, respectively.

The Company determines its discount rate assumption for its pension retirement obligations based on indices for AA corporate bonds with an average duration of approximately 20 years for the Japan pension plans and 17 years for the U.S. pension plans, and determination of the U.S. pension plans discount rate utilizes the 85-year extrapolated yield

curve. In Japan, participant salary and future salary increases are not factors in determining pension benefit cost or the related pension benefit obligation.


The Company bases its assumption for the long-term rate of return on assets on historical trends (10-year or longer historical rates of return for the Japanese plan assets and 15-year historical rates of return for the U.S. plan assets), expected future market movement, as well as the portfolio mix of securities in the asset portfolio including, but not limited to, style, class and equity and fixed income allocations. In addition, the Company's consulting actuaries evaluate its assumptions for long-term rates of return under Actuarial Standards of Practice (ASOP). Under the ASOP, the actual portfolio type, mix and class is modeled to determine a best estimate of the long-term rate of return. The Company in turn use those results to further validate its own assumptions.

Assumed health care cost trend rates have a significant effect on the amounts reported for the health care plan. A one-percentage point increase and decrease in assumed health care cost trend rates would have the following effects as of December 31, 2017:

NoNaN transition obligations arose during 2017, and the transition obligations amortized to expense were immaterial for the years ended December 31, 2017, 2016 and 2015. Amortization of actuarial losses to expense in 2018 is estimated to be $1 million for the Japanese plans, $16 million for the U.S. plans and $1 million for the other postretirement benefits plan. Amortization of prior service costs and credits and transition obligations for all plans is expected to be negligible in 2018.2019.

Funding


The Company plans to make contributions of $34$35 million to the Japanese funded defined benefit plan and $10 millionin 2020. The Company does not plan to make any contributions to the U.S. funded defined benefit plan in 2018.2020. The Company funded additional contributions to the U.S. funded defined benefit plan in 2019.

Plan Assets


The investment objective of the Company's Japanese and U.S. funded defined benefit plans is to preserve the purchasing power of the plan's assets and earn a reasonable inflation-adjusted rate of return over the long term. Furthermore, the Company seeks to accomplish these objectives in a manner that allows for the adequate funding of plan benefits and expenses. In order to achieve these objectives, the Company's goal is to maintain a conservative, well-diversified and balanced portfolio of high-quality equity, fixed-income and money market securities. As a part of its strategy, the Company has established strict policies covering quality, type and concentration of investment securities. For the Company's Japanese plan, these policies include limitations on investments in derivatives including futures, options and swaps, and low-liquidity investments such as real estate, venture capital investments, and privately issued securities. For the Company's U.S. plan, these policies prohibit investments in precious metals, limited partnerships, venture capital, and direct investments in real estate. The Company is also prohibited from trading on margin.


The plan fiduciaries for the Company's funded defined benefit plans have developed guidelines for asset allocations reflecting a percentage of total assets by asset class, which are reviewed on an annual basis. Asset allocation targets as of December 31, 20172019 were as follows:

  Japan Pension U.S. Pension

Guaranty Fund Assessments


The United StatesU.S. insurance industry has a policyholder protection system that is monitored and regulated by state insurance departments. These life and health insurance guaranty associations are state entities (in all 50 states as well as Puerto Rico and the District of Columbia) created to protect policyholders of an insolvent insurance company. All insurance companies (with limited exceptions) licensed to sell life or health insurance in a state must be members of that state’s guaranty association. Under state guaranty association laws, certain insurance companies can be assessed (up to prescribed limits) for certain obligations to the policyholders and claimants of impaired or insolvent insurance companies that write the same line or similar lines of business.


In 2009, the Pennsylvania Insurance Commissioner placed long-term care insurer Penn Treaty Network America Insurance Company and its subsidiary American Network Insurance Company (collectively referred to as Penn Treaty), neither of which is affiliated with Aflac, in rehabilitation and petitioned a state court for approval to liquidate Penn Treaty. A final order of liquidation was granted by a recognized judicial authority on March 1, 2017, and as a result, Penn Treaty is in the process of liquidation. The Company estimated and recognized the impact of its share of guaranty fund assessments resulting from the liquidation using a discounted rate of 4.25%. The Company recognized a discounted liability for the assessments of $62 million (undiscounted $94 million), offset by discounted premium tax credits of $48 million (undiscounted $74 million), for a net $14 million impact to net income in the quarter ended March 31, 2017. The Company paid a majority of these assessments during the past year. A majority of the resulting tax credits will be realized over the next five years.by March 31, 2019. The Company used the cost estimate provided as of the liquidation date by the National Organization of Life and Health Guaranty Associations (NOLHGA) to calculate its estimated assessments and tax credits. Other guaranty fund assessments for the years ended December 31, 2017, 2016,2019, 2018, and 20152017 were immaterial.

ITEM 16. FORM 10-K SUMMARY
Not applicable


173



Glossary of Selected Terms

Throughout this Annual Report on Form 10-K, the Company may use certain terms which are defined below.

Adjusted Earnings Per Diluted Share Excluding the
Impact of Foreign Currency – Adjusted earnings are adjusted revenues less benefits and adjusted expenses. The adjustments to both revenues and expenses account for certain items that cannot be predicted or that are outside management’s control. Adjusted revenues are U.S. GAAP total revenues excluding realized investment gains and losses, except for amortized hedge costs/income related to foreign currency exposure management strategies and net interest cash flows from derivatives associated with certain investment strategies. Adjusted expenses are U.S. GAAP total acquisition and operating expenses including the impact of interest cash flows from derivatives associated with notes payable but excluding any nonrecurring or other items not associated with the normal course of the company’s insurance operations and that do not reflect Aflac’s underlying business performance. The most comparable U.S. GAAP measure is net earnings. Adjusted earnings per share (basic or diluted) are the adjusted earnings for the period divided by the weighted average outstanding shares (basic or diluted) for the period presented. The most comparable U.S. GAAP measure is net earnings per share. This metric is then adjusted using the average yen/dollar exchange rate for the comparable prior year period, which eliminates dollar based fluctuations driven solely from currency rate changes.

Affiliated Corporate Agency – Agency in Japan directly affiliated with a specific corporation that sells insurance policies primarily to its employees

Annualized premiums in forcethe amount of gross premium that a policyholder must pay over a full year in order to keep coverage. The growth of net premiums (defined below) is directly affected by the change in premiums in force and by the change in weighted-average yen/dollar exchange rates.

Earnings Per Basic Share – Net earnings divided by weighted-average number of shares outstanding for the period

Earnings Per Diluted Share – Net earnings divided by the weighted-average number of shares outstanding for the period plus the weighted-average shares for the dilutive effect of share-based awards outstanding

Group Insurance Insurance issued to a group, such as an employer or trade association, that covers employees or association members and their dependents through certificates of coverage

Individual Insurance – Insurance issued to an individual with the policy designed to cover that person and his or her dependents

In-force PoliciesA count of policies that are active contracts at the end of a period.
Net Investment Income – The income derived from interest and dividends on invested assets, after deducting investment expenses

Net premiums – (sometimes referred to as net premium income or net earned premiums) is a financial measure that appears on the Company's Consolidated Statements of Earnings and in its segment reporting. This measure reflects collected or due premiums that have been earned ratably on policies in force during the reporting period, reduced by premiums that have been ceded to third parties and increased by premiums assumed through reinsurance.

New Annualized Premium Sales – (sometimes referred to as new sales or sales) An operating measure that is not reflected on the Company's financial statements. New annualized premium sales generally represent annual premiums on policies the Company sold and incremental increases from policy conversions that would be collected over a 12-month period assuming the policies remain in force for that entire period. For Aflac Japan, new annualized premium sales are determined by applications submitted during the reporting period. For Aflac U.S., new annualized premium sales are determined by applications that are issued during the reporting period. Policy conversions are defined as the positive difference in the annualized premium when a policy upgrades in the current reporting period.

Persistency – Percentage of premiums remaining in force at the end of a period, usually one year. For example, 95% persistency would mean that 95% of the premiums in force at the beginning of the period were still in force at the end of the period

Risk-based Capital (RBC) Ratio – Statutory adjusted capital divided by statutory required capital. This insurance ratio is based on rules prescribed by the National Association of Insurance Commissioners (NAIC) and provides an indication of the amount of statutory capital the insurance company maintains, relative to the inherent risks in the insurer’s operations

Solvency Margin Ratio (SMR) – Solvency margin total divided by one half of the risk total. This insurance ratio is prescribed by the Japan Financial Services Agency (FSA) and is used for all life insurance companies in Japan to measure the adequacy of the company’s ability to pay policyholder claims in the event actual risks exceed expected levels

Total Return to Shareholders – Appreciation of a shareholder’s investment over a period of time, including reinvested cash dividends paid during that time
