Organization, Consolidation and Presentation of Financial Statements [Abstract] | |
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES | 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) in the 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 of Aflac. The Company’s operations consist of two reportable business segments: Aflac U.S., which includes Aflac, and 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 U.S. and 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 68% of the Company's total revenues in 2020, compared with 69% in 2019 and 70% in 2018. The percentage of the Company's total assets attributable to Aflac Japan was 83% at both December 31, 2020 and 2019. 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. 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. The contingent consideration was completed in 2020 with a payment of approximately $14 million. Argus is an addition to the Aflac U.S. segment. In November 2020, the Company, through its insurance subsidiaries Aflac and Aflac New York, acquired Zurich North America’s U.S. Corporate Life and Pensions business (Zurich), which consists of group life, disability and absence management products for total consideration of $140 million. Aflac and Aflac New York will reinsure on an indemnity basis Zurich's in-force group life and disability policies. Aflac also acquired assets needed to support the group life and disability business, along with an absence management platform. Basis of Presentation The Company prepares its financial statements in accordance with U.S. generally accepted accounting principles (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 Codification TM (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 are 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. COVID-19: The impact of the COVID-19 global pandemic on the Company continues to evolve, and its future effects remain uncertain. The Company continues to closely monitor the effects and risks of COVID-19 to assess its impact on economic conditions in Japan and the U.S. and on the Company's business, financial condition, results of operations, liquidity and capital position. Liquidity and Capital Resources The Company entered the crisis having maintained capital ratios in Japan and the U.S. at a level designed to absorb a degree of market volatility. To further support liquidity and capital resources, the Parent Company, in March 2020, issued four series of senior notes totaling ¥57.0 billion and, in April 2020, issued $1.0 billion in senior notes through public debt offerings under its U.S. shelf registration statement. The Company has available liquidity in its unsecured revolving credit facilities of $1.0 billion and ¥100.0 billion and currently has no borrowings under either of these facilities. In April 2020, Aflac increased its internal limit for Federal Home Loan Bank of Atlanta (FHLB) borrowings to $800 million, $300 million of which the Company has designated to be used for short-term liquidity needs of the U.S. insurance subsidiaries and subject to qualified collateral availability and other conditions. The Company has the ability to adjust cash flow management from other sources of liquidity including reinvestment cash flows and selling investments. Loan Modifications In March 2020, the Coronavirus, Aid, Relief, and Economic Security (CARES) Act, which provides relief from certain requirements under GAAP, was signed into law. Section 4013 of the CARES Act gives entities temporary relief from the accounting and disclosure requirements for troubled debt restructurings (TDRs) under ASC 310-40 in certain situations. In April 2020, certain regulatory banking agencies, in consultation with the FASB, issued the Interagency Statement on Loan Modifications and Reporting for Financial Institutions Working with Customers Affected by the Coronavirus (Interagency statement) applicable for all entities, which offers practical expedients for evaluating whether loan modifications in response to the COVID-19 pandemic are treated as TDRs. The relief provided by the CARES Act applies to loan modifications made between March 1, 2020 and December 31, 2020, whereas the Interagency statement does not specify a time horizon. In December 2020, the Consolidated Appropriations Act, 2021 (CAA) was signed into law. The CAA extends certain provisions of the CARES Act, provides additional funding for others and contains new relief provisions. The CAA modifies a number of existing loan programs. The relief from TDR accounting will apply to modifications executed between March 1, 2020 and the earlier of (1) 60 days after the end of the COVID-19 national emergency as determined by the Executive Branch and (2) January 1, 2022. The Company applies relief granted under Section 4013 of the CARES Act and the Interagency statement with respect to certain qualifying loan modifications. For loan modifications that qualify under the CARES Act, TDR accounting and reporting is suspended through the period of the modification; however, the Company will continue to apply its existing non-accrual policies including consideration of the loan's past due status which is determined on the basis of the contractual terms of the loan. Once a loan has been contractually modified, the past due status is generally based on the updated terms including payment deferrals. See Note 3 of Notes to the Consolidated Financial Statements for additional details. Significant Accounting Policies Foreign Currency Translation: The functional currency of Aflac Japan 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. The Company includes in earnings the realized currency exchange gains and losses resulting from foreign currency transactions. The Parent Company has designated a majority of its yen-denominated liabilities (notes payable and yen-denominated loans) as non-derivative hedges and from time-to-time may designate certain foreign currency forwards and options as derivative hedges of the foreign currency exposure of the Company's net investment in Aflac Japan. Outstanding principal and related accrued interest on these Parent Company liabilities and the fair value of these derivatives are translated into U.S. dollars at end-of-period exchange rates. Currency translation adjustments and changes in the fair value of these 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: 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 the contract period; however, the Company may adjust premiums for supplemental health policies issued in the U.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 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 maturity debt 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 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 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 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 contractual terms, there are certain powers 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; 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 significant powers because 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 have 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 are segregated on the balance sheet by the caption "consolidated variable interest entities," and consist of fixed maturity securities, equity securities, loan receivables, limited partnerships and derivative instruments. For the mortgage- and asset-backed securities held in the Company's fixed maturity 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. The Company lends fixed maturity and public equity securities to financial institutions in short-term security-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). The Company's investments in TREs, CMLs, and MMLs are accounted for as loan receivables and are recorded at amortized cost on the acquisition date. The 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 amortized cost in the commercial mortgage and other loans line in its consolidated balance sheets. The amortized cost of the loan receivables reflects allowances for expected lifetime losses estimated 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 partnerships 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 and real estate. Short-term investments are stated at amortized cost, which approximates fair value. Credit Losses: Effective January 1, 2020, the Company adopted ASC 326: Financial Instruments - Credit Losses . The newly adopted accounting standard requires the Company to estimate an expected lifetime credit loss on financial assets measured at amortized cost including short-term receivables including premiums receivable, held-to-maturity fixed maturity securities, loan receivables, loan commitments and reinsurance recoverables. For the Company’s available-for-sale fixed maturity securities, the newly adopted guidance requires an entity to evaluate estimated credit losses only when the fair value of the available-for-sale fixed maturity security is below its amortized cost basis. Credit loss changes are recorded as a component of net investment gains and losses for the Company’s held-to-maturity and available-for-sale securities, loan receivables, loan commitments and reinsurance recoverables, whereas credit losses on premium receivables are recorded in net premiums. The Company’s off-balance sheet credit exposure is primarily attributable to loan commitments that are not unconditionally cancellable. The Company considers the contractual period of exposure to credit risk, the likelihood that funding will occur, the risk of loss, and the current conditions and expectations of future economic conditions to develop the estimate of expected credit losses. The Company records the estimate of expected credit losses for certain loan commitments within other liabilities in the consolidated balance sheet. Write-offs and partial write-offs are recorded as a reduction to the amortized cost of the loan or fixed maturity security balance and a corresponding reduction to the credit allowance. The Company has elected not to measure an allowance on accrued interest income for all asset types, because the uncollectible accrued interest receivable is written off in a timely manner. The Company writes off accrued interest when it is more than ninety days past due by reducing interest income, which is a component of net investment income, in the consolidated statement of earnings. The Company records due premium receivable net of current expected credit losses in the receivables line item in the consolidated balance sheet, utilizing an aging methodology based on historical loss information, adjusted for current conditions and reasonable and supportable forecasts. Changes in the estimated credit losses related to premium receivable are recorded in net premiums in the consolidated statement of earnings. Prior to January 1, 2020, the Company presented losses in accordance with the then effective guidance, where the Company primarily evaluated the financial instrument’s and issuer’s creditworthiness to determine whether an impairment in value of the Company's fixed maturity securities was other-than-temporary. For fixed maturity securities, if, after monitoring and analyses, management believed that fair value would not recover to amortized cost, the Company recognized an other-than-temporary impairment. Once a security was considered to be other-than-temporarily impaired, the impairment loss was separated into two components: the portion of the impairment related to credit and the portion of the impairment related to factors other than credit. The Company recognized a charge to earnings for the credit-related portion of other-than-temporary impairments. Impairments related to factors other than credit were recorded in earnings in the event the Company intended to sell the security prior to the recovery of its amortized cost or if it was 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 were recorded in other comprehensive income. For loans receivable, the amortized cost of the loan receivables reflected allowances for incurred losses estimated based on past events and current economic conditions as of each reporting date. 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 foreign currency forwards, foreign currency options, foreign currency swaps, interest rate swaps and interest rate swaptions. 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 other 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 attributable to the hedged item. At the inception of hedging relationships the Company formally documents all relationships between hedging instruments and hedged items, as well as its risk-management objectives and strategies for undertaking the respective hedging relationship, and the methodology that will be used to assess the effectiveness of the hedge 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 documentation process includes linking derivatives and non-derivative financial instruments that are designated as hedges to specific assets or groups of assets or liabilities in the statement of financial position or to specific forecasted transactions and defining the effectiveness testing methods to be used. At the hedge 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 changes in fair value. For assessing hedge effectiveness, 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. For derivative instruments that are designated and qualify as cash flow hedges, 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. In cash flow hedges, all components of each derivative's gain or loss are included in the assessment of hedge effectiveness. For derivative instruments 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 gain or loss on the hedged item is recorded. When assessing the effectiveness of the Company's fair value hedges, the Company excludes the changes in fair value related to the difference between the spot and the forward rate on its foreign currency forwards, the fair value not resulting from fluctuations in spot currency rates on the final notional exchange on cross currency swaps, and the time value of money of foreign exchange options and interest rate swaptions. For interest rate swaptions and cross-currency interest rate swaps 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. As discussed in Note 4, from time to time the Company designates net investment hedges of its net investment in Aflac Japan. The Company makes its net investment hedge designation at the beginning of each quarter. For derivative hedging instruments designated as net investment hedges, Aflac follows the spot-rate method. According to that method, the change in fair value of the hedging instrument due to fluctuations in the spot exchange rate is recorded in the unrealized foreign currency component of other comprehensive income and reclassified to earnings only when the hedged net investment is sold, or when a liquidation of the respective net investment in the foreign entity is substantially completed. If and when a sale or liquidation occurs, the changes in fair value of the derivative deferred in the unrealized foreign currency component of other comprehensive 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 net 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 net 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 other gains (losses), which is a component of net 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 insurance contracts 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.

Segment Reporting [Abstract] | |
BUSINESS SEGMENT INFORMATION | BUSINESS SEGMENT AND FOREIGN INFORMATION The Company consists of two reportable insurance business segments: Aflac Japan and Aflac U.S., both of which sell supplemental health and life insurance. In addition, operating business units that are not individually reportable and business activities, including reinsurance retrocession activities, not included in Aflac Japan or Aflac U.S. are included in 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 adjusted 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 net 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 Company excludes income taxes related to operations to arrive at pretax adjusted earnings.

Investment | INVESTMENTS Net Investment Income The components of net investment income for the years ended December 31 were as follows: (In millions) 2020 2019 2018 Fixed maturity securities $ 3,113 $ 3,141 $ 3,142 Equity securities 29 37 38 Commercial mortgage and other loans 545 468 333 Other investments 145 53 36 Short-term investments and cash equivalents 18 56 41 Gross investment income 3,850 3,755 3,590 Less investment expenses 212 177 148 Net investment income $ 3,638 $ 3,578 $ 3,442 Investment Holdings The amortized cost for the Company's investments in fixed maturity securities, the cost for equity securities and the fair values of these investments at December 31 are shown in the following tables. 2020 (In millions) Allowance for Credit Losses Gross Gross Fair Securities available for sale, carried at fair Fixed maturity securities: Yen-denominated: Japan government and agencies $ 32,959 $ 0 $ 4,182 $ 52 $ 37,089 Municipalities 1,324 0 374 5 1,693 Mortgage- and asset-backed securities 342 0 27 1 368 Public utilities 4,777 0 1,096 1 5,872 Sovereign and supranational 981 0 108 0 1,089 Banks/financial institutions 7,552 0 886 102 8,336 Other corporate 8,114 0 1,747 37 9,824 Total yen-denominated 56,049 0 8,420 198 64,271 U.S. dollar-denominated: U.S. government and agencies 245 0 16 0 261 Municipalities 1,154 0 173 2 1,325 Mortgage- and asset-backed securities 667 0 8 5 670 Public utilities 4,013 0 947 15 4,945 Sovereign and supranational 232 0 64 3 293 Banks/financial institutions 2,973 0 758 7 3,724 Other corporate 26,297 38 4,385 251 30,393 Total U.S. dollar-denominated 35,581 38 6,351 283 41,611 Total securities available for sale $ 91,630 $ 38 $ 14,771 $ 481 $ 105,882 2019 (In millions) Gross Gross Fair Securities available for sale, carried at fair value Fixed maturity securities: Yen-denominated: Japan government and agencies $ 30,929 $ 5,169 $ 0 $ 36,098 Municipalities 516 116 3 629 Mortgage- and asset-backed securities 229 25 0 254 Public utilities 1,855 406 0 2,261 Sovereign and supranational 680 50 0 730 Banks/financial institutions 6,152 700 86 6,766 Other corporate 5,323 944 24 6,243 Total yen-denominated 45,684 7,410 113 52,981 U.S dollar-denominated: U.S. government and agencies 293 9 0 302 Municipalities 1,077 141 0 1,218 Mortgage- and asset-backed securities 149 7 0 156 Public utilities 3,804 725 10 4,519 Sovereign and supranational 239 73 0 312 Banks/financial institutions 2,879 646 4 3,521 Other corporate 25,246 3,255 248 28,253 Total U.S. dollar-denominated 33,687 4,856 262 38,281 Total securities available for sale $ 79,371 $ 12,266 $ 375 $ 91,262 2020 (In millions) Allowance for Credit Losses Net Carrying Amount Gross Gross Fair Securities held to maturity, carried at Fixed maturity securities: Yen-denominated: Japan government and agencies $ 23,448 $ 3 $ 23,445 $ 5,625 $ 0 $ 29,070 Municipalities 377 0 377 122 0 499 Public utilities 48 1 47 14 0 61 Sovereign and supranational 577 6 571 165 0 736 Other corporate 24 0 24 9 0 33 Total yen-denominated 24,474 10 24,464 5,935 0 30,399 Total securities held to maturity $ 24,474 $ 10 24,464 $ 5,935 $ 0 $ 30,399 2019 (In millions) Gross Gross Fair Securities held to maturity, carried at Fixed maturity securities: Yen-denominated: Japan government and agencies $ 22,241 $ 6,050 $ 0 $ 28,291 Municipalities 821 262 0 1,083 Mortgage- and asset-backed securities 16 1 0 17 Public utilities 2,535 419 0 2,954 Sovereign and supranational 1,123 197 0 1,320 Banks/financial institutions 916 105 3 1,018 Other corporate 2,433 485 7 2,911 Total yen-denominated 30,085 7,519 10 37,594 Total securities held to maturity $ 30,085 $ 7,519 $ 10 $ 37,594 2020 2019 (In millions) Fair Value Fair Value Equity securities, carried at fair value through net earnings: Equity securities: Yen-denominated $ 680 $ 658 U.S. dollar-denominated 603 144 Total equity securities $ 1,283 $ 802 The methods of determining the fair values of the Company's investments in fixed maturity securities and equity securities are described in Note 5. During 2020, as a result of the adoption of ASU 2019-04 discussed in Note 1, the Company reclassified $6.9 billion (at amortized cost) of pre-payable fixed-maturity securities from the held-to-maturity category to the available-for-sale category. This reclassification resulted in recording in accumulated other comprehensive income a net unrealized gain of $848 million on an after-tax basis . During 2019 and 2018, the Company did not reclassify any investments from the held-to-maturity category to the available-for-sale category. Contractual and Economic Maturities The contractual and economic maturities of the Company's investments in fixed maturity securities at December 31, 2020, were as follows: (In millions) Amortized Cost (1) Fair Available for sale: Due in one year or less $ 1,130 $ 1,125 Due after one year through five years 8,750 9,020 Due after five years through 10 years 13,752 15,945 Due after 10 years 66,951 78,754 Mortgage- and asset-backed securities 1,009 1,038 Total fixed maturity securities available for sale $ 91,592 $ 105,882 Held to maturity: Due in one year or less $ 0 $ 0 Due after one year through five years 0 0 Due after five years through 10 years 2,212 2,594 Due after 10 years 22,252 27,805 Mortgage- and asset-backed securities 0 0 Total fixed maturity securities held to maturity $ 24,464 $ 30,399 (1) Net of allowance for credit losses Economic maturities are used for certain debt instruments with no stated maturity where the expected maturity date is based on the combination of features in the financial instrument such as the right to call or prepay obligations or changes in coupon rates. 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. Investment exposures that individually exceeded 10% of shareholders' equity as of December 31 were as follows: 2020 2019 (In millions) Credit Amortized Fair Credit Amortized Fair Japan National Government (1) A+ $55,153 $64,657 A+ $51,726 $62,584 (1) Japan Government Bonds (JGBs) or JGB-backed securities Net Investment Gains and Losses Information regarding pretax net gains and losses from investments for the years ended December 31 follows: (In millions) 2020 2019 2018 Net investment gains (losses): Sales and redemptions: Fixed maturity securities available for sale: Gross gains from sales $ 31 $ 115 $ 101 Gross losses from sales (47) (68) (156) Foreign currency gains (losses) on sales and redemptions (69) (16) 73 Total sales and redemptions (85) 31 18 Equity securities 184 101 (131) Loan loss reserves (1) 0 (18) (19) Credit losses: Fixed maturity securities available for sale (2) (75) (13) (64) Fixed maturity securities held to maturity 1 0 0 Commercial mortgage and other loans (103) 0 0 Loan commitments (21) 0 0 Reinsurance recoverables and other (2) 0 0 Total credit losses (200) (13) (64) Derivatives and other: Derivative gains (losses) 399 (174) (224) Foreign currency gains (losses) (568) (62) (10) Total derivatives and other (169) (236) (234) Total net investment gains (losses) $ (270) $ (135) $ (430) (1) U.S. GAAP guidance adopted as of January 1, 2020 has superseded these losses, included for comparative purposes only (2) Includes other-than-temporary impairment losses for prior year The unrealized holding gains, net of losses, recorded as a component of net investment gains and losses for the year ended December 31, 2020, that relates to equity securities still held at the December 31, 2020, reporting date was $210 million. Unrealized Investment Gains and Losses Information regarding changes in unrealized gains and losses from investments recorded in AOCI for the years ended December 31 follows: (In millions) 2020 2019 2018 Changes in unrealized gains (losses): Fixed maturity securities, available for sale $ 2,399 $ 5,852 $ (3,142) Total change in unrealized gains (losses) $ 2,399 $ 5,852 $ (3,142) Effect on Shareholders' Equity The net effect on shareholders' equity of unrealized gains and losses from fixed maturity securities at December 31 was as follows: (In millions) 2020 2019 Unrealized gains (losses) on securities available for sale $ 14,290 $ 11,891 Deferred income taxes (3,929) (3,343) Shareholders’ equity, unrealized gains (losses) on fixed maturity securities $ 10,361 $ 8,548 Gross Unrealized Loss Aging The following tables show the fair values and gross unrealized losses of the Company's available-for-sale investments for the period ended December 31, 2020 and available-for-sale and held-to-maturity investments for prior periods that were in an unrealized loss position, aggregated by investment category and length of time that individual securities have been in a continuous unrealized loss position that were in an unrealized loss position. 2020 Total Less than 12 months 12 months or longer (In millions) Fair Unrealized Fair Unrealized Fair Unrealized Fixed maturity securities available Japan government and Yen-denominated $ 2,604 $ 52 $ 2,604 $ 52 $ 0 $ 0 Municipalities: U.S. dollar-denominated 94 2 94 2 0 0 Yen-denominated 183 5 169 4 14 1 Mortgage- and asset- U.S. dollar-denominated 360 5 360 5 0 0 Yen-denominated 37 1 37 1 0 0 Public utilities: U.S. dollar-denominated 326 15 208 7 118 8 Yen-denominated 135 1 135 1 0 0 Sovereign and supranational: U.S. dollar-denominated 39 3 39 3 0 0 Banks/financial institutions: U.S. dollar-denominated 82 7 44 1 38 6 Yen-denominated 1,809 102 765 36 1,044 66 Other corporate: U.S. dollar-denominated 4,499 251 2,157 59 2,342 192 Yen-denominated 613 37 290 13 323 24 Total $ 10,781 $ 481 $ 6,902 $ 184 $ 3,879 $ 297 2019 Total Less than 12 months 12 months or longer (In millions) Fair Unrealized Fair Unrealized Fair Unrealized Fixed maturity securities: Municipalities: Yen-denominated $ 80 $ 3 $ 80 $ 3 $ 0 $ 0 Public utilities: U.S. dollar-denominated 306 10 69 2 237 8 Banks/financial institutions: U.S. dollar-denominated 79 4 18 0 61 4 Yen-denominated 1,828 89 1,828 89 0 0 Other corporate: U.S. dollar-denominated 4,261 248 792 53 3,469 195 Yen-denominated 636 31 636 31 0 0 Total $ 7,190 $ 385 $ 3,423 $ 178 $ 3,767 $ 207 Analysis of Securities in Unrealized Loss Positions The unrealized losses on the Company's fixed maturity 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. For any significant declines in fair value of its fixed maturity securities, the Company performs a more focused review of the related issuers' credit profile. 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 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. Assuming no credit-related factors develop, unrealized gains and losses on fixed maturity securities are expected to diminish as investments near maturity. Based on its credit analysis, the Company believes that the issuers of its fixed maturity investments in the sectors shown in the table above have the ability to service their obligations to the Company, and the Company does not intend to sell the investments and it is not more likely than not that the Company will be required to sell the investments before recovery of their amortized cost bases, which may be at maturity. However, the Company has identified certain available-for-sale fixed maturity securities where the amortized cost basis exceeds the present value of the cash flows expected to be collected due to credit related factors and as a result, a credit allowance has been calculated. As of December 31, 2020, the Company held an allowance of $38 million. Refer to the Credit Losses section below for additional information. Commercial Mortgage and Other Loans The Company classifies its TREs, CMLs and MMLs as held-for-investment and includes them in the commercial mortgage and other loans line on the consolidated balance sheets. The Company carries them on the balance sheet at amortized cost less an estimated allowance for credit losses. The table below reflects the composition of the carrying value for commercial mortgage and other loans by property type as of December 31. (In millions) 2020 2019 Amortized Cost % of Total Amortized Cost % of Total Commercial Mortgage and other loans Transitional real estate loans: Office $ 2,115 19.7 % $ 1,800 18.7 % Retail 125 1.2 131 1.4 Apartments/Multi-Family 1,782 16.6 2,085 21.7 Industrial 85 .8 256 2.7 Hospitality 1,106 10.3 1,036 10.8 Other 81 .7 164 1.7 Total transitional real estate loans 5,294 49.3 5,472 57.0 Commercial mortgage loans: Office 401 3.7 410 4.3 Retail 340 3.2 348 3.5 Apartments/Multi-Family 588 5.5 569 5.9 Industrial 391 3.6 383 4.0 Total commercial mortgage loans 1,720 16.0 1,710 17.7 Middle market loans 3,720 34.7 2,432 25.3 Total commercial mortgage and other loans $ 10,734 100.0 % $ 9,614 100.0 % Allowance for credit losses (180) (45) (1) Total net commercial mortgage and other loans $ 10,554 $ 9,569 (1) U.S. GAAP guidance adopted as of January 1, 2020 has superseded these losses, included for comparative purposes only. Commercial mortgage and transitional real estate loans were secured by properties entirely within the U.S. (with the largest concentrations in California (21%), Texas (14%) and Florida (11%)). Middle market loans are issued only to companies domiciled within the U.S. and Canada. 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, 2020, the Company had $601 million in 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, 2020, the Company had $32 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 $25 million and $99 million for a short term credit facility that is reflected in other liabilities on the consolidated balance sheets, as of December 31, 2020, and 2019, respectively. As of December 31, 2020, the Company had commitments of approximately $2.2 billion of which $2.0 billion was a result of a new agreement with an external manager during the first quarter of 2020 to fund future middle market loans. These commitments are contingent upon the availability of middle market loans that meet the Company's underwriting criteria. Credit Quality Indicators For TREs, the Company’s key credit quality indicator is loan-to-value (LTV). Given that TRE loans involve properties undergoing renovation or construction, loan-to-value provides the most insight into the credit risk of the loan. The Company monitors the performance of the loans periodically, but not less frequently than quarterly. For CMLs, the Company’s key credit quality indicators include LTV and debt service coverage ratios (DSCR). LTV is calculated by dividing the current outstanding loan balance by the most recent estimated property value. DSCR is the most recently available operating income of the underlying property compared to the required debt service of the loan. For MMLs and held-to-maturity fixed maturity securities, the Company’s key credit quality indicator is credit ratings. The Company’s held-to-maturity portfolio is composed of investment grade securities that are senior unsecured instruments, while its MMLs generally have below-investment-grade ratings but are typically senior secured instruments. The Company monitors the credit ratings periodically, but not less frequently than quarterly. For the Company’s reinsurance recoverable balance, the key credit quality indicator is the credit rating of the Company’s reinsurance counterparty. The Company uses external credit ratings focused on the reinsurer’s financial strength and credit worthiness. The Company's counterparties are rated A+. The Company monitors the credit ratings periodically, but not less frequently than quarterly. The following tables present as of December 31, 2020 the amortized cost basis of TREs, CMLs and MMLs by year of origination and credit quality indicator .

For held-to-maturity fixed maturity securities, MMLs, and MML commitments, the Company groups assets by credit ratings, industry, and country. The Company groups CMLs and TREs and respective loan commitments by property type, property location and the property’s loan-to-value and debt service coverage ratios. The credit allowance for the reinsurance recoverable balance is estimated using a probability-of-default (PD) / loss-given-default (LGD) method. The credit allowance for held-to-maturity fixed maturity securities and loan receivables is estimated using a PD / LGD method, discounted for the time value of money. For held-to-maturity fixed maturity securities, available-for-sale fixed maturity securities and loan receivables, the Company includes the change in present value due to the passage of time in the change in the allowance for credit losses. The Company’s methodology for estimating credit losses utilizes the contractual maturity date of the financial asset, adjusted when necessary to reflect the expected timing of repayment (such as prepayment options, renewal options, call options, or extension options). The Company applies reasonable and supportable forecasts of macroeconomic variables that impact the determination of PD/LGD over a two-year period for held-to-maturity fixed maturity securities and MMLs. The Company reverts to historical loss information over one year, following the two-year forecast period. For the CML and TRE portfolio, the Company applies reasonable and supportable forecasts of macroeconomic variables as well as national and local real-estate market factors to estimate future credit losses where the market factors revert back to historical levels over time with the period being dependent on current market conditions, projected market conditions and difference in the current and historical market levels for each factor. The Company continuously monitors the estimation methodology, due to changes in portfolio composition, changes in underwriting practices and significant events or conditions and makes adjustments as necessary. The Company’s held-to-maturity fixed maturity portfolio includes Japan Government and Agency securities of $23.3 billion amortized cost as of December 31, 2020 that meet the requirements for zero-credit-loss expectation and therefore these asset classes have been excluded from the current expected credit loss measurement. An investment in an available-for-sale fixed maturity security is impaired if the fair value falls below amortized cost. The Company regularly reviews its fixed maturity security investments portfolio for declines in fair value. 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 methodology for estimating credit losses for available-for-sale fixed maturity securities utilizes the discounted cash flow model, based on past events, current market conditions and future economic conditions, as well as industry analysis and credit ratings of the fixed maturity securities. In addition, the Company evaluates the specific issuer’s probability of default and expected recovery of its position in the event of default based on the underlying financial condition and assets of the borrower as well as seniority and/or security of other debt holders in the issuer when developing management’s best estimate of expected cash flows. The Company granted certain loan modifications in its MML and TRE portfolios due to COVID-19 during the year ended December 31, 2020. As of December 31, 2020 loan modifications did not have a material impact on the Company’s results of operations. The nature of the modifications varied in scope and significance, but generally a small proportion of modifications qualified as TDR, which is a situation where a Company grants a concession to a borrower that a Company would not otherwise have considered due to the borrower’s financial difficulties. Additionally, in accordance with the FASB’s published response to a COVID-19 Pandemic technical inquiry, the Company continues to accrue interest income on such loans that have deferred payment. The Company continues to evaluate loan modifications in its MML and TRE portfolios. As of December 31, 2020, the amortized cost of modified loans where Section 4013 of the CARES Act, as extended by the CAA, or the Interagency statement is applicable was immaterial. The Company had an immaterial amount of TDRs during the year ended December 31, 2020. The Company had no TDRs during 2019 . For certain TDRs, modifications resulted in write-offs for certain loans where the modified loan resulted in a forgiveness of existing principal and are included in the rollforward of the allowance for credit losses below. The Company designates nonaccrual status for a nonperforming debt security or a loan that is not generating its stated interest rate because of nonpayment of periodic interest by the borrower. The Company applies the cash basis method to record any payments received on non-accrual assets. The Company resumes the accrual of interest on fixed maturity securities and loans that are currently making contractual payments or for those that are not current where the borrower has paid timely (less than 30 days outstanding). As of December 31, 2020 and 2019, the Company had an immaterial amount (cost basis) of loans and fixed maturities on nonaccrual status. The following table presents the roll forward of the allowance for credit losses by portfolio segment for the year ended December 31, 2020 .

For assets that are subject to the credit loss measurement, the change in credit loss allowance will be significantly impacted by purchases and sales in those assets during the period as well as entering into new non-cancelable loan commitments. During the first quarter of 2020, the Company entered into a loan commitment with an external manager that met the requirements to recognize a credit loss on over $2.2 billion of loan commitments over the next few years. The estimate of credit losses for loan commitments as of December 31, 2020 was $35 million. Other Investments The table below reflects the composition of the carrying value for other investments as of December 31. (In millions) 2020 2019 Other investments: Policy loans $ 260 $ 250 Short-term investments (1) 1,139 628 Limited partnerships 1,004 569 Other 26 30 Total other investments $ 2,429 $ 1,477 (1) Includes securities lending collateral As of December 31, 2020, the Company had $1.6 billion in outstanding commitments to fund alternative investments in limited partnerships. Variable Interest Entities (VIEs) As a condition of its involvement or investment in a VIE, the Company enters into certain protective rights and covenants that preclude changes in the structure of the VIE that would alter the creditworthiness of the Company's investment or its beneficial interest in the VIE. 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 which the Company holds debt obligations, the weighted-average lives of the Company's notes are very similar to the underlying collateral held by these VIEs where applicable. The Company's risk of loss related to its interests in any of its VIEs is limited to the carrying value of the related investments held in the VIE. VIEs - Consolidated The following table presents the cost or amortized cost, fair value and balance sheet caption in which the assets and liabilities of consolidated VIEs are reported as of December 31.

As the sole investor in these VIEs, the Company has the power to direct the activities of a variable interest entity that most significantly impact the entity's economic performance and is therefore considered to be the primary beneficiary of the VIEs that it consolidates. The Company also participates in substantially all of the variability created by these VIEs. The activities of these VIEs are limited to holding invested assets and foreign currency swaps, as appropriate, and utilizing the cash flows from these securities to service its investment. Neither the Company nor any of its creditors are able to obtain the underlying collateral of the VIEs unless there is an event of default or other specified event. For those VIEs that contain a swap, the Company is not a direct counterparty to the swap contracts and has no control over them. The Company's loss exposure to these VIEs is limited to its original investment. The Company's consolidated VIEs do not rely on outside or ongoing sources of funding to support their activities beyond the underlying collateral and swap contracts, if applicable. With the exception of its investment in unit trust structures, the underlying collateral assets and funding of the Company's consolidated VIEs are generally static in nature. Investments in Unit Trust Structures The Company also utilizes unit trust structures in its Aflac Japan segment to invest in various asset classes. As the sole investor of these VIEs, the Company is required to consolidate these trusts under U.S. GAAP. VIEs - Not Consolidated The table below reflects the amortized cost, fair value and balance sheet caption in which the Company's investment in VIEs not consolidated are reported as of December 31.

Derivative Instruments and Hedging Activities Disclosure [Abstract] | |
DERIVATIVE INSTRUMENTS | DERIVATIVE INSTRUMENTS The Company's freestanding derivative financial instruments have historically consisted of: • foreign currency forwards and options used in hedging foreign exchange risk on U.S. dollar-denominated investments in Aflac Japan's portfolio • foreign currency forwards and options used to economically hedge certain portions of forecasted cash flows denominated in yen and hedge the Company's 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 subordinated debentures • foreign currency swaps that are associated with VIE bond purchase commitments, and investments in special-purpose entities, including VIEs where the Company is the primary beneficiary • interest rate swaps used to economically hedge interest rate fluctuations in certain variable-rate investments • interest rate swaptions used to hedge changes in the fair value associated with interest rate fluctuations for certain U.S. dollar-denominated available-for-sale fixed-maturity securities • bond purchase commitments at the inception of investments in consolidated VIEs. 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 accounting 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 is 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. In forward transactions, Aflac Japan agrees with another party to buy a fixed amount of yen and sell a corresponding amount of U.S. dollars at a specified future date. Aflac Japan also executes foreign currency option transactions in a collar strategy, where Aflac Japan agrees with another party to simultaneously purchase put options and sell call options. In the purchased put transactions, Aflac Japan obtains the option to buy a fixed amount of yen and sell a corresponding amount of U.S. dollars at a specified future date. In the sold call transaction, Aflac Japan agrees to sell a fixed amount of yen and buy a corresponding amount of U.S. dollars at a specified future date. The combination of purchasing the put option and selling the call option results in no net premium being paid (i.e. a costless or zero-cost collar). In the first quarter of 2020, the Company reduced the size of the collar program by approximately $3 billion. In December 2020, the Company reduced the total size of the forward and collar programs by approximately $5 billion and purchased foreign currency options to hedge approximately $5 billion of U.S. dollar-denominated assets. From time to time, the Company may also enter into foreign currency forwards and options to hedge the currency risk associated with the net investment in Aflac Japan. In these forward transactions, Aflac agrees with another party to buy a fixed amount of U.S. dollars and sell a corresponding amount of yen at a specified price at a specified future date. In the option transactions, the Company may use a combination of foreign currency options to protect expected future cash flows by simultaneously purchasing yen put options (options that protect against a weakening yen) and selling yen call options (options that limit participation in a strengthening yen). The combination of these two actions create a zero-cost collar. Additionally, the Company enters into purchased options to hedge cash flows from the net investment in Aflac Japan. 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 principal amounts at a future 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. In order to reduce investment income volatility from its variable-rate investments, the Company enters into receive–fixed, pay–floating interest rate swaps. These derivatives are cleared and settled through a central clearinghouse. Swaptions are used to mitigate the adverse impact resulting from significant changes in the fair value of U.S. dollar-denominated available-for-sale securities due to fluctuation in interest rates. In a payer swaption, the Company pays a premium to obtain the right, but not the obligation, to enter into a swap contract where it will pay a fixed rate and receive a floating rate. Interest rate swaption collars are combinations of two swaption positions. In order to maximize the efficiency of the collars while minimizing cost, a collar strategy is used whereby the Company purchases a long payer swaption (the Company purchases an option that allows it to enter into a swap where the Company will pay the fixed rate and receive the floating rate of the swap) and sells a short receiver swaption (the Company sells an option that provides the counterparty with the right to enter into a swap where the Company will receive the fixed rate and pay the floating rate of the swap). The combination of purchasing the long payer swaption and selling the short receiver swaption results in no net premium being paid (i.e. a costless or zero-cost collar). Bond purchase commitments result from repackaged bond structures that are consolidated VIEs whereby there is a delay in the trade date and settlement date of the bond within the structure to ensure completion of all necessary legal agreements to support the consolidated VIE that issues the repackaged bond. Since the Company has a commitment to purchase the underlying bond at a specified price, the agreement meets the definition of a derivative where the value is derived based on the current market value of the bond compared to the fixed purchase price to be paid on the settlement date. Derivative Balance Sheet Classification The table below summarizes the balance sheet classification of the Company's derivative fair value amounts, as well as the gross asset and liability fair value amounts, at December 31. The fair value amounts presented do not include income accruals. Derivative assets are included in “Other Assets,” while derivative liabilities are included in “Other Liabilities” within the Company’s Consolidated Balance Sheets. The notional amount of derivative contracts represents the basis upon which pay or receive amounts are calculated and are not reflective of exposure or credit risk. 2020 2019 (In millions) Asset Liability Asset Liability Hedge Designation/ Derivative Notional Fair Value Fair Value Notional Fair Value Fair Value Cash flow hedges: Foreign currency swaps - VIE $ 18 $ 0 $ 1 $ 75 $ 0 $ 8 Total cash flow hedges 18 0 1 75 0 8 Fair value hedges: Foreign currency forwards 64 2 0 964 0 38 Foreign currency options 8,865 0 0 11,573 0 5 Interest rate swaptions 0 0 0 243 0 0 Total fair value hedges 8,929 2 0 12,780 0 43 Net investment hedge: Foreign currency forwards 5,010 14 84 4,952 72 2 Foreign currency options 2,027 1 0 2,000 0 0 Total net investment hedge 7,037 15 84 6,952 72 2 Non-qualifying strategies: Foreign currency swaps 2,250 47 81 2,800 72 78 Foreign currency swaps - VIE 2,857 133 230 2,587 169 118 Foreign currency forwards 26,528 386 301 19,821 166 337 Foreign currency options 11,037 0 0 9,553 0 0 Interest rate swaps 0 0 0 7,120 3 0 Interest rate swaptions 0 0 0 7 0 0 Total non-qualifying 42,672 566 612 41,888 410 533 Total derivatives $ 58,656 $ 583 $ 697 $ 61,695 $ 482 $ 586 Cash Flow Hedges For certain variable-rate U.S. dollar-denominated available-for-sale securities held by Aflac Japan via consolidated VIEs, foreign currency swaps are used to swap the USD variable rate interest and principal payments to fixed rate JPY interest and principal payments. The Company has designated foreign currency swaps as a hedge of the variability in cash flows of a forecasted transaction or of amounts to be received or paid related to a recognized asset (“cash flow” hedge). The remaining maximum length of time for which these cash flows are hedged is six years. The derivatives in the Company's consolidated VIEs that are not designated as accounting hedges are discussed in the "non-qualifying strategies" section of this note. Fair Value Hedges The Company designates and accounts for certain foreign currency forwards, options, and interest rate swaptions as fair value hedges when they meet the requirements for hedge accounting. The Company recognizes gains and losses on these derivatives as well as the offsetting gain or loss on the related hedged items in current earnings. Foreign currency forwards and options hedge the foreign currency exposure of certain U.S. dollar-denominated available-for-sale fixed-maturity investments held in Aflac Japan. The change in the fair value of the foreign currency forwards related to the changes in the difference between the spot rate and the forward price is excluded from the assessment of hedge effectiveness. The change in fair value of the foreign currency option related to the time value of the option is recognized in current earnings and is excluded from the assessment of hedge effectiveness. Interest rate swaptions hedge the interest rate exposure of certain U.S. dollar-denominated available-for-sale securities held in Aflac Japan. For these hedging relationships, the Company excludes time value from the assessment of hedge effectiveness and recognizes changes in the intrinsic value of the swaptions in current earnings within net investment income. The change in the time value of the swaptions is recognized in other comprehensive income (loss) and amortized into earnings (net investment income) over its legal term. The following table presents the gains and losses on derivatives and the related hedged items in fair value hedges for the years ended December 31.

It also includes the change in the fair value of the interest rate swaptions related to the time value of the swaptions which is recognized as a component of other comprehensive income (loss). (2) Gains and losses on foreign currency forwards and options and related hedged items are reported in the consolidated statement of earnings as net investment gains (losses). For interest rate swaptions and related hedged items, gains and losses included in the hedge assessment, premium amortization and time value amortization while the hedge items are still outstanding are reported within net investment income. The time value gains and losses for interest rate swaptions when the related hedged items are redeemed are reported in net investment gains and losses consistent with the impact of the hedged item. For the years ended December 31, 2020 and 2019, gains and losses included in the hedge assessment on interest rate swaptions and related hedged items were immaterial. The following table shows the carrying amounts of assets designated and qualifying as hedged items in fair value hedges of interest rate risk and the related cumulative hedge adjustment included in the carrying amount as of December 31. (In millions) Carrying Amount of the Hedged Assets/(Liabilities) (1) Cumulative Amount of Fair Value Hedging Adjustment Included in the Carrying Amount of Hedged Assets/(Liabilities) 2020 2019 2020 2019 Fixed maturity securities $ 4,331 $ 4,633 $ 237 $ 256 (1) The balance includes hedging adjustment on discontinued hedging relationships of $237 in 2020 and $256 in 2019. The total notional amount of the Company's interest rate swaptions was $0 in 2020 and $243 in 2019. The hedging adjustment related to these derivatives was immaterial. 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 Parent Company's yen-denominated liabilities (see Note 9) have been designated as non-derivative hedges. Beginning in July 2019, certain foreign currency forwards and options were designated as derivative hedges of the foreign currency exposure of the Company's net investment in Aflac Japan. The Company's net investment hedge was effective during the years ended December 31, 2020, 2019 and 2018. 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 net 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 securities associated with these swaps is recorded through other comprehensive income. As of December 31, 2020, the Parent Company had $2.3 billion notional amount of cross-currency interest rate swap agreements related to certain of its U.S. dollar-denominated senior notes to effectively convert a portion of the interest on the notes from U.S dollar to Japanese yen. Changes in the values of these swaps are recorded through current period earnings. For additional information regarding these swaps, see Note 9. The Company uses foreign exchange forwards and options to economically mitigate the currency risk of some of its U.S. dollar-denominated loan receivables held within the Aflac Japan segment. These arrangements are not designated as accounting hedges, as the foreign currency remeasurement of the loan receivables impacts current period earnings, and generally offsets gains and losses from foreign exchange forwards within net investment gains (losses). The Company also has certain foreign exchange forwards on U.S. dollar-denominated available-for-sale securities where hedge accounting is not being applied. Prior to July 2019, in order to economically mitigate currency risk of future yen dividends from Aflac Japan while lowering consolidated hedge costs associated with Aflac Japan's U.S. dollar investment hedging, the Parent Company entered into offsetting hedge positions using foreign exchange forwards. 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. Impact of Derivatives and Hedging Instruments The following table summarizes the impact to earnings and other comprehensive income (loss) from all derivatives and hedging instruments for the years ended December 31. 2020 2019 2018 (In millions) Net Investment Income (1) Net Investment Other (2) Net Investment Income (1) Net Investment Other (2) Net Investment Income (1) Net Investment Other (2) Qualifying hedges: Cash flow hedges: Foreign currency swaps - VIE $ (1) $ 0 $ (2) $ (2) $ (1) $ (4) $ 0 $ 0 $ 3 Total cash flow hedges (1) 0 (3) (2) (2) (1) (3) (4) 0 0 (3) 3 Fair value hedges: Foreign currency forwards (3) (7) (62) (116) Foreign currency options (3) (8) (7) 4 Interest rate swaptions (3) (1) 0 1 (1) 0 (8) 0 0 (1) Total fair value hedges (1) (15) 1 (1) (69) (8) 0 (112) (1) Net investment hedge: Non-derivative hedging 0 (135) 0 (24) 0 (32) Foreign currency forwards 149 (282) 10 83 0 0 Foreign currency options (5) 0 (4) 0 0 (8) Total net investment hedge 144 (417) 6 59 0 (40) Non-qualifying strategies: Foreign currency swaps 29 90 (40) Foreign currency swaps - VIE (122) (68) 60 Foreign currency forwards 311 (148) (135) Foreign currency options (3) 0 0 Interest rate swaps 49 17 3 Forward bond purchase 6 0 0 Total non-qualifying strategies 270 (110) (112) Total $ (2) $ 399 $ (418) $ (3) $ (174) $ 47 $ 0 $ (224) $ (38) (1) Interest expense/income on cash flow hedges are recorded in net investment income. For interest rate swaptions classified as fair value hedges, the change in the time value of the swaptions is recognized in other comprehensive income (loss) and amortized into net investment income over its legal term. If the swaption is early terminated but the hedge item is still outstanding, the amortization of disposal amount of the swaptions is recorded in net investment income over the remaining life of the hedged items. (2) Gains and losses on cash flow hedges and the change in the fair value of interest rate swaptions related to the time value of the swaptions in fair value hedges are recorded as unrealized gains (losses). Gains and losses on net investment hedges related to change in foreign currency spot rates are recorded in the unrealized foreign currency translation gains (losses) line in the consolidated statement of comprehensive income (loss). (3) Impact of cash flow hedges reported as net investment gains (losses) includes an immaterial amount of gains or losses reclassified from accumulated other comprehensive income (loss) into earnings. It also includes an immaterial amount excluded from effectiveness testing during the years ended December 31, 2020, 2019 and 2018, respectively. Impact shown net of effect of hedged items (see Fair Value Hedges section of this Note 4 for further detail) As of December 31, 2020, $5 million of deferred losses on derivative instruments recorded in accumulated other comprehensive income are expected to be reclassified into earnings during the next twelve months. Credit Risk Assumed through Derivatives 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 loss due to counterparty default even though it is not a direct counterparty to those contracts. 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 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 forwards, and foreign currency options is mitigated by collateral posting requirements that counterparties to those transactions must meet. As of December 31, 2020, all of the Company's derivative agreement counterparties 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 $268 million and $301 million as of December 31, 2020 and 2019, respectively. If the credit-risk-related contingent features underlying these agreements had been triggered on December 31, 2020, the Company estimates that it would be required to post a maximum of $156 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 its subsidiaries and the 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.

Fair Value Disclosures [Abstract] | |
FAIR VALUE MEASUREMENTS | 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.

A third party pricing vendor has developed valuation models to determine fair values of privately issued securities. These models are discounted cash flow (DCF) valuation models, but also use information from related markets, specifically the credit default swaps (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 2) issuer-specific CDS spreads 3) bonds or CDS spreads of comparable issuers with similar characteristics such as rating, geography, 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 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. Beginning in the third quarter of 2020, the Company refined these valuation models to explicitly incorporate currency basis swap adjustments (market observable data) to assumed interest rate curves where appropriate. 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. For the periods presented, the Company has not adjusted the quotes or prices it obtains from the pricing services and brokers it uses.

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 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 Company uses present value techniques to value non-option based derivatives. It also uses option pricing models to value option based derivatives. Key inputs are as follows: Instrument Type Level 2 Level 3 Interest rate derivatives Swap yield curves Basic curves Interest rate volatility (1) Not applicable Foreign currency exchange rate derivatives - Non-VIES (forwards, swaps and options) Foreign currency forward rates Swap yield curves Basis curves Foreign currency spot rates Cross foreign currency basis curves Foreign currency volatility (1) Not applicable Foreign currency exchange rate derivatives - VIEs (swaps) Foreign currency spot rates Swap yield curves (2) Credit default swap curves (2) Basis curves (2) Recovery rates Foreign currency forward rates (2) Foreign cross currency basis curves (2) (1) Option-based only (2) Extrapolation beyond the observable limits of the curve(s). The fair values of the foreign currency forwards and options are based on observable market inputs, therefore they are classified as Level 2. The Parent Company has cross-currency swap agreements related to certain of its U.S. dollar-denominated senior notes to effectively convert a portion of the interest on the notes from U.S dollar to Japanese yen. Their fair values are 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. Based on 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 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. For forward bond purchase commitments with VIEs, the fair value of the derivative is based on the difference in the fixed purchase price and the current market value of the related bond prior to the settlement date. Since the bond is typically a public bond with readily available pricing, the derivatives associated with the forward purchase commitment are classified as Level 2 of the fair value hierarchy. Commercial mortgage and other loans Commercial mortgage and other 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. 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 Transfers between Hierarchy Levels and Level 3 Rollforward The following tables present the changes in fair value of the Company's investments and derivatives carried at fair value classified as Level 3 as of December 31. 2020 Fixed Maturity Securities Equity Derivatives (1) (In millions) Mortgage- Public Sovereign Banks/ Other Foreign Total Balance, beginning of period $ 178 $ 224 $ 0 $ 23 $ 262 $ 80 $ 43 $ 810 Net investment gains (losses) 0 (1) 0 0 0 16 (139) (124) Unrealized gains (losses) 9 19 0 0 12 0 (2) 38 Purchases, issuances, sales Purchases 30 174 48 1 39 14 0 306 Issuances 0 0 0 0 0 0 0 0 Sales 0 0 0 0 0 (6) 0 (6) Settlements (2) (9) 0 0 (1) 0 0 (12) Transfers into Level 3 9 (2) 15 (3) 0 0 2 0 0 26 Transfers out of Level 3 0 0 0 0 (15) (3) (2) 0 (17) Balance, end of period $ 224 $ 422 $ 48 $ 24 $ 299 $ 102 $ (98) $ 1,021 Changes in unrealized gains $ 0 $ 0 $ 0 $ 0 $ 0 $ 0 $ (139) $ (139) (1) Derivative assets and liabilities are presented net (2) Transfer due to reclassification of level 3 securities from HTM to AFS (3) Transfer due to sector classification change 2019 Fixed Maturity Securities Equity Derivatives (1) (In millions) Mortgage- Public Banks/ Other Foreign Total Balance, beginning of period $ 177 $ 109 $ 23 $ 213 $ 46 $ 80 $ 648 Net investment gains (losses) included in 0 0 0 (1) 0 (33) (34) Unrealized gains (losses) included in other 1 6 1 8 0 (4) 12 Purchases, issuances, sales and settlements: Purchases 0 48 0 165 34 0 247 Issuances 0 0 0 0 0 0 0 Sales 0 (24) 0 (17) 0 0 (41) Settlements 0 (6) 0 0 0 0 (6) Transfers into Level 3 0 116 (2) 0 26 (2) 0 0 142 Transfers out of Level 3 0 (25) (2) (1) (132) (2),(3) 0 0 (158) Balance, end of period $ 178 $ 224 $ 23 $ 262 $ 80 $ 43 $ 810 Changes in unrealized gains (losses) relating $ 0 $ 0 $ 0 $ 0 $ 0 $ (33) $ (33) (1) Derivative assets and liabilities are presented net (2) Transfer due to sector classification change (3) Transfer due to availability of observable market inputs Level 3 Significant Unobservable Input Sensitivity The following tables summarize the significant unobservable inputs used in the valuation of the Company's Level 3 investments and derivatives carried at fair value as of December 31.

(b) Inputs derived from U.S. long-term rates to accommodate long maturity nature of the Company's swaps (c) Inputs derived from Japan long-term rates to accommodate long maturity nature of the Company's swaps 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 of equity 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 The significant drivers of the valuation of the foreign exchange swaps are interest rates and CDS spreads. Some of the Company's swaps have long maturities that increase the sensitivity of the swaps to interest rate fluctuations. For the Company's foreign exchange or cross currency swaps that are in a net asset position, an increase in yen interest rates (all other factors held constant) will decrease the present value of the yen final settlement receivable (receive leg), thus decreasing the value of the 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 amounts at the termination of the swap. Assuming all other factors are held constant, an increase in yen interest rates will decrease the receive leg and decrease the net value of the swap. Likewise, holding all other factors constant, an increase in U.S. dollar interest rates will increase the swap's net value due to the decrease in the present value of the 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.

POLICY LIABILITIES | POLICY LIABILITIES Policy liabilities consist of future policy benefits, unpaid policy claims, unearned premiums, and other policyholders' funds, which accounted for 85%, 5%, 3% and 7% of total policy liabilities at December 31, 2020, respectively. The Company regularly reviews the adequacy of its policy liabilities in total and by component. The liability for future policy benefits as of December 31 consisted of the following: Liability Amounts Interest Rate Assumptions (In millions) 2020 2019 Health insurance Japan $ 54,659 $ 50,941 0.6 - 6.75 % U.S. 8,834 8,646 3.0 - 8.0 Intercompany eliminations (1) (545) (532) 2.0 Life insurance Japan 33,993 30,520 0.6 - 4.5 U.S. 842 760 2.5 - 6.0 Total $ 97,783 $ 90,335 (1) Elimination entry necessary due to recapture of a portion of policy liabilities ceded externally, as a result of the reinsurance retrocession transaction as described in Note 8 of the Notes to the Consolidated Financial Statements The weighted-average interest rates reflected in the consolidated statements of earnings for future policy benefits for Japanese policies were 3.1% in 2020, compared with 3.2% in 2019 and 3.3% in 2018; and for U.S. policies, 5.2% in 2020, compared with 5.3% in 2019 and 2018. Changes in the liability for unpaid policy claims were as follows for the years ended December 31: (In millions) 2020 2019 2018 Unpaid supplemental health claims, beginning of period $ 3,968 $ 3,952 $ 3,884 Less reinsurance recoverables 30 27 30 Net balance, beginning of period 3,938 3,925 3,854 Add claims incurred during the period related to: Current year 7,179 7,216 7,101 Prior years (540) (552) (563) Total incurred 6,639 6,664 6,538 Less claims paid during the period on claims incurred during: Current year 4,488 4,715 4,612 Prior years 1,966 1,965 1,898 Total paid 6,454 6,680 6,510 Effect of foreign exchange rate changes on unpaid claims 128 29 43 Zurich acquisition 99 0 0 Net balance, end of period 4,350 3,938 3,925 Add reinsurance recoverables 39 30 27 Unpaid supplemental health claims, end of period 4,389 3,968 3,952 Unpaid life claims, end of period 798 691 632 Total liability for unpaid policy claims $ 5,187 $ 4,659 $ 4,584 The incurred claims development related to prior years reflects favorable claims experience compared to previous estimates. The favorable claims development of $540 million for 2020 comprises approximately $334 million from Japan and $206 million from the U.S., representing approximately 62% and 38% of the total, respectively. Excluding the impact of foreign exchange of a gain of approximately $7 million from December 31, 2019 to December 31, 2020, the favorable claims development in Japan would have been approximately $327 million, representing approximately 61% of the total. The Company has experienced continued favorable claim trends in 2020 for its core health products in Japan. During the year, there were impacts from lower utilization of healthcare services, due to the COVID-19 pandemic. This impacted both cancer and medical products, as the Japan population was avoiding doctor and hospital visits, and was staying home more. This resulted in lower sickness, accident, and cancer incurred claims. Also, 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. For the majority of the Company's major U.S. accident and health lines of business, including accident, hospital indemnity, cancer, critical illness and short-term disability, the incurred claims development related to prior years reflects favorable claims experience compared to previous estimates. The decrease in current year incurred claims in 2020 primarily reflects a decrease in Aflac U.S. claims as a result of reduced accidents, wellness medical visits and routine procedures due to shelter-in-place orders and heightened social distancing due to COVID-19, offset somewhat by COVID-19 claims. As of December 31, 2020 and 2019, 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 60% of the December 31, 2020 and 64% of the December 31, 2019 unearned premiums balances. As of December 31, 2020 and 2019, the largest component of the other policyholders' funds liability was the Company's annuity line of business in Aflac Japan. The Company's annuities have fixed benefits and premiums. These annuities represented 97% of other policyholders' funds liability at December 31, 2020 and 2019. |

Reinsurance Disclosures [Abstract] | |
REINSURANCE | 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. The Company has recorded a deferred profit liability related to reinsurance transactions. The remaining deferred profit liability of $1.0 billion, as of December 31, 2020, 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 $1.0 billion and $970 million as of December 31, 2020 and 2019, 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 5.9% and ceded reserves increased approximately 8.9% from December 31, 2019 to December 31, 2020. The following table reconciles direct premium income and direct benefits and claims to net amounts after the effect of reinsurance which also includes the elimination of inter-segment amounts associated with affiliated reinsurance for the years ended December 31. (In millions) 2020 2019 2018 Direct premium income $ 18,955 $ 19,122 $ 19,018 Ceded to other companies: Ceded Aflac Japan closed blocks (466) (478) (497) Other (87) (69) (58) Assumed from other companies: Retrocession activities 195 200 208 Other 25 5 6 Net premium income $ 18,622 $ 18,780 $ 18,677 Direct benefits and claims $ 12,080 $ 12,237 $ 12,293 Ceded benefits and change in reserves for future benefits: Ceded Aflac Japan closed blocks (419) (433) (450) Eliminations 39 41 43 Other (63) (57) (44) Assumed from other companies: Retrocession activities 180 194 209 Eliminations (39) (41) (53) Other 18 1 2 Benefits and claims, net $ 11,796 $ 11,942 $ 12,000 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, with reserves of approximately ¥120 billion as of December 31, 2020. This reinsurance facility agreement was renewed in 2020 and is effective until December 31, 2021. 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. The reinsurer can withdraw from the committed facility if Aflac‘s Standard and Poor's (S&P) rating drops below BBB-. As of December 31, 2020, the Company had not executed a reinsurance treaty under this committed reinsurance facility. |

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.

INCOME TAXES | INCOME TAXES The components of income tax expense (benefit) applicable to pretax earnings for the years ended December 31 were as follows: (In millions) Foreign U.S. Total 2020: Current $ 822 $ (28) $ 794 Deferred (28) (1,385) (1,413) Total income tax expense $ 794 $ (1,413) $ (619) 2019: Current $ 737 $ 69 $ 806 Deferred 183 152 335 Total income tax expense $ 920 $ 221 $ 1,141 2018: Current $ 771 $ 608 $ 1,379 Deferred 93 (409) (316) Total income tax expense $ 864 $ 199 $ 1,063 The Japan income tax rate for the fiscal years 2018, 2019 and 2020 was 28.0%. For the 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 imposed a broad number of changes in tax law, including permanently 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. In March 2020, the Coronavirus Aid, Relief, and Economic Security (CARES) Act was signed into law and includes certain income tax provisions relevant to businesses. The Company was required to recognize the effect on the consolidated financial statements in the period the law was enacted, which was the period ended March 31, 2020. For the year ended December 31, 2020, the CARES Act did not have a material impact on the Company’s consolidated financial statements. In September 2020, the U.S. Treasury and Internal Revenue Service issued Final and Proposed Regulations which address, among other items, the allocation of insurance expenses in the calculation of the foreign tax credit limitation. These regulations clarify how insurance related expenses are allocated and apportioned for this purpose. The Company had previously established valuation allowances on deferred foreign tax credits due to the uncertainty that previously existed. Under the guidance of these regulations, the Company recognized a one-time income tax benefit of $1.4 billion due to the release of these valuation allowances which were predominantly established on the Company’s deferred foreign tax credit benefits. The Company has determined that this will also reduce its effective tax rate in future periods, subject to any future changes in U.S. tax policy. 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 2020, 2019 and 2018 to pretax earnings. The principal reasons for the differences and the related tax effects for the years ended December 31 were as follows: (In millions) 2020 2019 2018 Income taxes based on U.S. statutory rates $ 873 $ 933 $ 836 Foreign rate differential 0 229 220 Valuation allowance release (1,411) 0 0 Other, net (81) (21) 7 Income tax expense $ (619) $ 1,141 $ 1,063 Total income tax expense for the years ended December 31 was allocated as follows: (In millions) 2020 2019 2018 Statements of earnings $ (619) $ 1,141 $ 1,063 Other comprehensive income (loss): Unrealized foreign currency translation gains (losses) during (3) 27 10 Unrealized gains (losses) on fixed maturity securities: Unrealized holding gains (losses) on fixed maturity 223 1,532 (787) Reclassification adjustment for (gains) losses 33 5 (12) Unrealized gains (losses) on derivatives during period 0 (3) 0 Pension liability adjustment during period (2) (18) (8) Total income tax expense (benefit) related to items of 251 1,543 (797) Total income taxes $ (368) $ 2,684 $ 266 The income tax effects of the temporary differences that gave rise to deferred income tax assets and liabilities as of December 31 were as follows: (In millions) 2020 2019 Deferred income tax liabilities: Deferred policy acquisition costs $ 3,663 $ 3,492 Unrealized gains and other basis differences on investments 5,227 4,485 Foreign currency gain on Aflac Japan 70 0 Premiums receivable 112 152 Policy benefit reserves 3,834 3,442 Total deferred income tax liabilities 12,906 11,571 Deferred income tax assets: Unfunded retirement benefits 9 8 Other accrued expenses 37 36 Policy and contract claims 868 781 Foreign currency loss on Aflac Japan 0 16 Deferred compensation 137 162 Capital loss carryforwards 12 34 Depreciation 202 164 Anticipatory foreign tax credit 5,972 5,487 Deferred foreign tax credit 647 605 Other 326 204 Total deferred income tax assets before valuation allowance 8,210 7,497 Valuation allowance 0 (1,340) Total deferred income tax assets after valuation allowance 8,210 6,157 Net deferred income tax liability 4,696 5,414 Current income tax (asset) liability (35) (44) Total income tax liability $ 4,661 $ 5,370 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. The Company has determined no valuation allowance against its anticipatory foreign tax credits 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 release of the valuation allowance on the anticipatory foreign tax credit is due to the regulations addressing the allocation of insurance expenses in the calculation of the foreign tax credit released September 29, 2020. The Company has also determined no 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 2021 due to Japan's current tax year not closing until March 31, 2021. The release of the valuation allowance on the deferred foreign tax credit is also due to the foreign tax credit regulations released September 29, 2020. 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 items noted above, it is more likely than not that all other deferred tax assets will be realized. Under U.S. income tax rules, only 35% of non-life operating losses can be offset against life insurance taxable income each year. For current U.S. income tax purposes, as of December 31, 2020, there were non-life operating loss carryforwards of $298 million available to offset against future taxable income, all of which do not expire. The Company has capital loss carryforwards of $55 million available to offset capital gains, all of which expire in 2025. The Company has foreign tax credit carryforwards of $22 million available to offset against future excess foreign taxes paid, all of which expire in 2031. The Company files federal income tax returns in the U.S. and Japan as well as state or prefecture income tax returns in various jurisdictions in the two countries. The Company is currently under audit by the IRS for the 2013-2018 amended federal income tax returns. There are currently no other open Federal, State, or local U.S. income tax audits. U.S. federal income tax returns for years before 2016 are no longer subject to examination. Japan corporate income tax returns for years before 2016 are no longer subject to examination. 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) 2020 2019 Balance, beginning of year $ 17 $ 15 Additions for tax positions of prior years 2 2 Balance, end of year $ 19 $ 17 Included in the balance of the liability for unrecognized tax benefits at December 31, 2020, are $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 $15 million at December 31, 2019. 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 $4 million as of December 31, 2020, 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 2020, compared with $1 million in 2019 and $1 million in 2018. The Company has accrued approximately $3 million for the payment of interest and penalties as of December 31, 2020, compared with $2 million at December 31, 2019. As of December 31, 2020, 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. |

Share-based Payment Arrangement [Abstract] | |
SHARE-BASED COMPENSATION | SHARE-BASED COMPENSATION In June 2020, the Company transitioned from E*Trade Financial Corporate Services, Inc. to Fidelity Management Trust Company as the trustee and recordkeeper of the Company's long-term share-based compensation plans. As of December 31, 2020, the Company has outstanding share-based awards under the Aflac Incorporated Long-Term Incentive Plan (the 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 75 million shares including 38 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. 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, restricted stock, and stock appreciation rights. As of December 31, 2020, approximately 38.0 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, 2020, the only performance-based awards issued and outstanding were restricted stock 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 . 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 Share-based compensation expense consists primarily of expenses for stock options, restricted stock awards (including performance based restricted stock awards), and restricted stock units granted to employees. The following table presents the impact of the expense recognized in connection with share-based awards for the periods ended December 31. (In millions, except for per-share amounts) 2020 2019 2018 Impact on earnings from continuing operations $ 61 $ 59 $ 57 Impact on earnings before income taxes 61 59 57 Impact on net earnings 48 46 45 Impact on net earnings per share: Basic $ .07 $ .06 $ .06 Diluted .07 .06 .06 Stock Options The following table summarizes stock option activity under the employee stock option plan.

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. The weighted-average fair value of options at their grant date was $6.33 in 2020 and $8.81 in 2018. There were no options granted in 2019. The following table presents the assumptions used in valuing options granted during the years ended December 31. 2020 2019 2018 Expected term (years) 6.0 7.0 7.0 Expected volatility 24.4 % 18.0 % 22.0 % Annual forfeiture rate 3.9 3.9 3.6 Risk-free interest rate 2.0 2.9 2.5 Dividend yield 3.3 2.2 2.4 The following table summarizes information about stock options outstanding and exercisable at December 31, 2020.

As of December 31, 2020, the aggregate intrinsic value of stock options outstanding was $43 million, with a weighted-average remaining term of 3.9 years. The total number of in-the-money stock options exercisable as of December 31, 2020, was 3.0 million shares. The aggregate intrinsic value of stock options exercisable at that same date was $43 million, with a weighted-average remaining term of 3.8 years.

PBRS are generally granted at-the-money and contingently cliff vest over a period of three years, generally subject to continued employment. In February 2020, the Company granted 409 thousand performance-based stock awards, which are contingent on the achievement of the Company's financial performance metrics and its market-based conditions. On the date of grant, the Company estimated 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 pay-out estimate will 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 2020, the Company granted 9 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 The Company uses third-party analyses to assist in developing the assumptions used in, as well as calibrating, a 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 2020 follows: (In millions) 2020 Expected volatility (based on Aflac Inc. and peer group historical daily stock price) 16.13 % Expected life from grant date (years) 2.9 Risk-free interest rate (based on U.S. Treasury yields at the date of grant) 1.42 % Restricted Stock Awards and Units The value of restricted stock awards and restricted stock units is based on the fair market value of the Company's common stock at the date of grant.

STATUTORY ACCOUNTING AND DIVIDEND RESTRICTIONS | STATUTORY ACCOUNTING AND DIVIDEND RESTRICTIONS The Company's insurance subsidiaries are required to report their results of operations and financial position to insurance regulatory authorities on the basis of statutory accounting practices prescribed or permitted by such authorities. 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. 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). Capital and surplus of Aflac Japan, based on Japanese regulatory accounting practices, was $9.0 billion at December 31, 2020, compared with $7.8 billion at December 31, 2019. Aflac, CAIC and TOIC report 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. Aflac New York reports statutory financial statements that are prepared on the basis of accounting practices prescribed or permitted by the New York State Department of Financial Services (NYDFS). The NYDFS recognizes statutory accounting principles and practices prescribed or permitted by the state of New York for determining and reporting the financial condition and results of operations of an insurance company, and for determining a company's solvency under New York insurance law. Statutory Accounting Principles (SAP) as detailed by the National Association of Insurance Commissioners' (NAIC) Accounting Practices and Procedures Manual has been adopted by both the state of Nebraska and the state of New York as a component of those prescribed or permitted practices. 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. Additionally, the Director of the NDOI and the Superintendent of the NYDFS each have the right to permit other specific practices which deviate from prescribed practices. Aflac, CAIC, TOIC and Aflac New York had no permitted practices as of December 31, 2020 and 2019. The table below represents statutory capital and surplus based on statutory accounting practices for the Company’s U.S. life insurance subsidiaries as of December 31. (In millions) 2020 2019 Aflac $ 2,088 $ 2,122 CAIC 271 128 TOIC 61 12 Aflac New York 352 320 As of December 31, 2020, the capital and surplus for each of the Company's U.S. life insurance subsidiaries exceeded the required company action level capital and surplus. The table below represents net income (loss) based on statutory accounting practices for the Company’s U.S. life insurance subsidiaries as of December 31. (In millions) 2020 2019 2018 Aflac $ 872 $ 864 $ 1,331 CAIC 1 (16) 6 TOIC (24) (2) 0 Aflac New York 75 75 67 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 subsidiaries may fluctuate due to different accounting methods required by regulatory authorities. These payments are also subject to various regulatory restrictions and approvals related to safeguarding the interests of insurance policyholders. The company's U.S. life insurance entities must maintain adequate RBC for U.S. regulatory authorities, and Aflac Japan must maintain adequate solvency margins for Japanese regulatory authorities. 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 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 2020, Aflac declared dividends of $853 million. Dividends declared by Aflac during 2021 in excess of $872 million would require such approval. CAIC and TOIC did not declare dividends during 2020. From time to time, Aflac New York pays dividends to Aflac, the parent company of Aflac New York. Aflac New York may not pay dividends to Aflac without the prior approval of the NYDFS. Aflac New York declared dividends of $30 million in 2020, which were authorized by the NYDFS. After 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, could be remitted 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 remittances to the U.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 remitted 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: In Dollars In Yen (In millions of dollars and billions of yen) 2020 2019 2018 2020 2019 2018 Profit remittances $ 1,215 $ 2,070 $ 808 ¥ 129.8 ¥ 225.2 ¥ 89.7 |

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. Components of Net Periodic Benefit Cost Pension and other postretirement benefit expenses are included in acquisition and operating expenses in the consolidated statements of earnings, which includes $30 million, $8 million and $25 million of other components of net periodic pension cost and postretirement costs (other than services costs) for the years ended December 31, 2020, 2019 and 2018, respectively.

The Company does not plan to make any contributions to the U.S. funded defined benefit plan in 2021. The Company funded contributions of $100 million to the U.S. funded defined benefit plan in 2020. The funding policy for the Company's non-qualified supplemental defined benefit pension plans and other postretirement benefits plan is to contribute the amount of the benefit payments made during the year. 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, 2020 were as follows: Japan Pension U.S. Pension Domestic equities 5 % 40 % International equities 21 20 Fixed income securities 65 40 Other 9 0 Total 100 % 100 % The U.S. Pension Plan had $169 million in cash at December 31, 2020. The plan fiduciaries authorized investing contributions made to the Plan in 2019 and 2020 on a graduated basis over a period of time. The following table presents the fair value of Aflac Japan's pension plan assets that are measured at fair value on a recurring basis as of December 31.

The fair values of the Company's pension plan investments classified as Level 2 are based on quoted prices for similar assets in markets that are not active, other inputs that are observable, such as interest rates, yield curves, volatilities, prepayment speeds, loss severities, credit risks, and default rates, or other market-corroborated inputs. 401(k) Plan The Company sponsors a 401(k) plan in which it matches a portion of U.S. employees' contributions. The plan provides for salary reduction contributions by employees and provides for matching contributions which, starting January 1, 2018, the Company increased to 100% of each employee's contributions which were not in excess of 4% of the employee's annual cash compensation as a result of tax reform. The Company also provides a nonelective contribution to the 401(k) plan of 2% of annual cash compensation for employees who opted out of the future benefits of the U.S. defined benefit plan and for new U.S. employees. Effective January 1, 2021, the Company increased this nonelective contribution to 4% of annual compensation. The 401(k) contributions by the Company, included in acquisition and operating expenses in the consolidated statements of earnings, were $20 million in 2020 and $18 million in both 2019 and 2018. The plan trustee held approximately 2.5 million shares of the Company's common stock for plan participants at December 31, 2020. Stock Bonus Plan Aflac U.S. maintains a stock bonus plan for eligible U.S. sales associates. Plan participants receive shares of Aflac Incorporated common stock based on their new annualized premium sales and their first-year persistency of substantially all new insurance policies. The cost of this plan, which was capitalized as deferred policy acquisition costs, amounted to $24 million in 2020 and $31 million in both 2019 and 2018. Voluntary Separation Program In September 2020, the Company announced a voluntary separation program for certain U.S. employees. The program provides eligible employees with a severance package, including twelve months of salary, the employee's targeted bonus payout for 2020 and one year of Consolidated Omnibus Budget Reconciliation Act (COBRA) or retiree medical, if eligible. Employees accepted into this program were notified in October 2020 and most transitions were completed by December 31, 2020, with a small number continuing into the first quarter of 2021. The Company recorded a one-time severance charge of $43 million in the fourth quarter of 2020 related to the program. |

COMMITMENTS AND CONTINGENT LIABILITIES | COMMITMENTS AND CONTINGENT LIABILITIESThe Company has two outsourcing agreements with a technology and consulting corporation. The first agreement provides mainframe computer operations, distributed mid-range server computer operations, and related support for Aflac Japan. It has a remaining term of two years and an aggregate remaining cost of ¥17.5 billion ($169 million using the December 31, 2020, exchange rate). The second agreement provides application maintenance and development services for Aflac Japan. It has a remaining term of three years and an aggregate remaining cost of ¥4.6 billion ($45 million using the December 31, 2020, exchange rate). The Company has one outsourcing agreement with a management consulting and technology services company to provide application maintenance and development services for its Japanese operation. The agreement has a remaining term of one year with an aggregate remaining cost of ¥3.3 billion ($32 million using the December 31, 2020, exchange rate). The Company has two outsourcing agreements with information technology and data services companies to provide application maintenance and development services for its Japanese operation. The first agreement has a remaining term of two years with an aggregate remaining cost of ¥3.0 billion ($29 million using the December 31, 2020, exchange rate). The second agreement has a remaining term of five years with an aggregate remaining cost of ¥13.7 billion ($133 million using the December 31, 2020, exchange rate). 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. See Note 3 of the Notes to the Consolidated Financial Statements for details on certain investment commitments. Guaranty Fund Assessments The U.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 by December 31, 2020. 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, 2020, 2019, and 2018 were immaterial. |

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 45 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 March 2020, the Parent Company issued four series of senior notes totaling ¥57.0 billion through a public debt offering under its U.S. shelf registration statement.

Organization, Consolidation and Presentation of Financial Statements [Abstract] | |
Description of Business and Basis of Presentation | 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) in the 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 of Aflac. The Company’s operations consist of two reportable business segments: Aflac U.S., which includes Aflac, and 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 U.S. and 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 68% of the Company's total revenues in 2020, compared with 69% in 2019 and 70% in 2018. The percentage of the Company's total assets attributable to Aflac Japan was 83% at both December 31, 2020 and 2019. 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. 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. The contingent consideration was completed in 2020 with a payment of approximately $14 million. Argus is an addition to the Aflac U.S. segment. In November 2020, the Company, through its insurance subsidiaries Aflac and Aflac New York, acquired Zurich North America’s U.S. Corporate Life and Pensions business (Zurich), which consists of group life, disability and absence management products for total consideration of $140 million. Aflac and Aflac New York will reinsure on an indemnity basis Zurich's in-force group life and disability policies. Aflac also acquired assets needed to support the group life and disability business, along with an absence management platform. Basis of Presentation The Company prepares its financial statements in accordance with U.S. generally accepted accounting principles (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 Codification TM (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 are 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. COVID-19: The impact of the COVID-19 global pandemic on the Company continues to evolve, and its future effects remain uncertain. The Company continues to closely monitor the effects and risks of COVID-19 to assess its impact on economic conditions in Japan and the U.S. and on the Company's business, financial condition, results of operations, liquidity and capital position. Liquidity and Capital Resources The Company entered the crisis having maintained capital ratios in Japan and the U.S. at a level designed to absorb a degree of market volatility. To further support liquidity and capital resources, the Parent Company, in March 2020, issued four series of senior notes totaling ¥57.0 billion and, in April 2020, issued $1.0 billion in senior notes through public debt offerings under its U.S. shelf registration statement. The Company has available liquidity in its unsecured revolving credit facilities of $1.0 billion and ¥100.0 billion and currently has no borrowings under either of these facilities. In April 2020, Aflac increased its internal limit for Federal Home Loan Bank of Atlanta (FHLB) borrowings to $800 million, $300 million of which the Company has designated to be used for short-term liquidity needs of the U.S. insurance subsidiaries and subject to qualified collateral availability and other conditions. The Company has the ability to adjust cash flow management from other sources of liquidity including reinvestment cash flows and selling investments. Loan Modifications In March 2020, the Coronavirus, Aid, Relief, and Economic Security (CARES) Act, which provides relief from certain requirements under GAAP, was signed into law. Section 4013 of the CARES Act gives entities temporary relief from the accounting and disclosure requirements for troubled debt restructurings (TDRs) under ASC 310-40 in certain situations. In April 2020, certain regulatory banking agencies, in consultation with the FASB, issued the Interagency Statement on Loan Modifications and Reporting for Financial Institutions Working with Customers Affected by the Coronavirus |
Translation of Foreign Currencies | Foreign Currency Translation: The functional currency of Aflac Japan 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. The Company includes in earnings the realized currency exchange gains and losses resulting from foreign currency transactions. The Parent Company has designated a majority of its yen-denominated liabilities (notes payable and yen-denominated loans) as non-derivative hedges and from time-to-time may designate certain foreign currency forwards and options as derivative hedges of the foreign currency exposure of the Company's net investment in Aflac Japan. Outstanding principal and related accrued interest on these Parent Company liabilities and the fair value of these derivatives are translated into U.S. dollars at end-of-period exchange rates. Currency translation adjustments and changes in the fair value of these 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 | Insurance Revenue and Expense Recognition: 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 the contract period; however, the Company may adjust premiums for supplemental health policies issued in the U.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. |
Advertising Cost, Policy, Expensed Advertising Cost | Advertising expense is reported as incurred in insurance expenses in the consolidated statements of earnings. |
Cash and Cash Equivalents | 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 | Investments: The Company's debt securities consist of fixed 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 maturity debt 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 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 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 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 contractual terms, there are certain powers 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; 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 significant powers because 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 have 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 are segregated on the balance sheet by the caption "consolidated variable interest entities," and consist of fixed maturity securities, equity securities, loan receivables, limited partnerships and derivative instruments. For the mortgage- and asset-backed securities held in the Company's fixed maturity 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. The Company lends fixed maturity and public equity securities to financial institutions in short-term security-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). The Company's investments in TREs, CMLs, and MMLs are accounted for as loan receivables and are recorded at amortized cost on the acquisition date. The 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 amortized cost in the commercial mortgage and other loans line in its consolidated balance sheets. The amortized cost of the loan receivables reflects allowances for expected lifetime losses estimated 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 partnerships 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 and real estate. Short-term investments are stated at amortized cost, which approximates fair value. Credit Losses: Effective January 1, 2020, the Company adopted ASC 326: Financial Instruments - Credit Losses . The newly adopted accounting standard requires the Company to estimate an expected lifetime credit loss on financial assets measured at amortized cost including short-term receivables including premiums receivable, held-to-maturity fixed maturity securities, loan receivables, loan commitments and reinsurance recoverables. For the Company’s available-for-sale fixed maturity securities, the newly adopted guidance requires an entity to evaluate estimated credit losses only when the fair value of the available-for-sale fixed maturity security is below its amortized cost basis. Credit loss changes are recorded as a component of net investment gains and losses for the Company’s held-to-maturity and available-for-sale securities, loan receivables, loan commitments and reinsurance recoverables, whereas credit losses on premium receivables are recorded in net premiums. The Company’s off-balance sheet credit exposure is primarily attributable to loan commitments that are not unconditionally cancellable. The Company considers the contractual period of exposure to credit risk, the likelihood that funding will occur, the risk of loss, and the current conditions and expectations of future economic conditions to develop the estimate of expected credit losses. The Company records the estimate of expected credit losses for certain loan commitments within other liabilities in the consolidated balance sheet. Write-offs and partial write-offs are recorded as a reduction to the amortized cost of the loan or fixed maturity security balance and a corresponding reduction to the credit allowance. The Company has elected not to measure an allowance on accrued interest income for all asset types, because the uncollectible accrued interest receivable is written off in a timely manner. The Company writes off accrued interest when it is more than ninety days past due by reducing interest income, which is a component of net investment income, in the consolidated statement of earnings. The Company records due premium receivable net of current expected credit losses in the receivables line item in the consolidated balance sheet, utilizing an aging methodology based on historical loss information, adjusted for current conditions and reasonable and supportable forecasts. Changes in the estimated credit losses related to premium receivable are recorded in net premiums in the consolidated statement of earnings. Prior to January 1, 2020, the Company presented losses in accordance with the then effective guidance, where the Company primarily evaluated the financial instrument’s and issuer’s creditworthiness to determine whether an impairment in value of the Company's fixed maturity securities was other-than-temporary. For fixed maturity securities, if, after monitoring and analyses, management believed that fair value would not recover to amortized cost, the Company recognized an other-than-temporary impairment. Once a security was considered to be other-than-temporarily impaired, the impairment loss was separated into two components: the portion of the impairment related to credit and the portion of the impairment related to factors other than credit. The Company recognized a charge to earnings for the credit-related portion of other-than-temporary impairments. Impairments related to factors other than credit were recorded in earnings in the event the Company intended to sell the security prior to the recovery of its amortized cost or if it was 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 were recorded in other comprehensive income. For loans receivable, the amortized cost of the loan receivables reflected allowances for incurred losses estimated based on past events and current economic conditions as of each reporting date. |
Derivatives and Hedging | 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 foreign currency forwards, foreign currency options, foreign currency swaps, interest rate swaps and interest rate swaptions. 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 other 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 attributable to the hedged item. At the inception of hedging relationships the Company formally documents all relationships between hedging instruments and hedged items, as well as its risk-management objectives and strategies for undertaking the respective hedging relationship, and the methodology that will be used to assess the effectiveness of the hedge 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 documentation process includes linking derivatives and non-derivative financial instruments that are designated as hedges to specific assets or groups of assets or liabilities in the statement of financial position or to specific forecasted transactions and defining the effectiveness testing methods to be used. At the hedge 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 changes in fair value. For assessing hedge effectiveness, 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. For derivative instruments that are designated and qualify as cash flow hedges, 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. In cash flow hedges, all components of each derivative's gain or loss are included in the assessment of hedge effectiveness. For derivative instruments 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 gain or loss on the hedged item is recorded. When assessing the effectiveness of the Company's fair value hedges, the Company excludes the changes in fair value related to the difference between the spot and the forward rate on its foreign currency forwards, the fair value not resulting from fluctuations in spot currency rates on the final notional exchange on cross currency swaps, and the time value of money of foreign exchange options and interest rate swaptions. For interest rate swaptions and cross-currency interest rate swaps 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. As discussed in Note 4, from time to time the Company designates net investment hedges of its net investment in Aflac Japan. The Company makes its net investment hedge designation at the beginning of each quarter. For derivative hedging instruments designated as net investment hedges, Aflac follows the spot-rate method. According to that method, the change in fair value of the hedging instrument due to fluctuations in the spot exchange rate is recorded in the unrealized foreign currency component of other comprehensive income and reclassified to earnings only when the hedged net investment is sold, or when a liquidation of the respective net investment in the foreign entity is substantially completed. If and when a sale or liquidation occurs, the changes in fair value of the derivative deferred in the unrealized foreign currency component of other comprehensive 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 net 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 net 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 other gains (losses), which is a component of net 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. |
Deferred Policy Acquisition Costs | Deferred Policy Acquisition Costs: Certain direct and incremental costs of acquiring insurance contracts 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 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 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 | Policy Liabilities: Future policy benefits represent insurance claims that are expected to occur in the future and are computed following 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. |
Policy Liabilities - Unpaid Policy Claims | 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. |
Unearned Premiums | Unearned 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 Policy Liabilities | Other policyholders’ funds liability consists primarily of the fixed annuity line of business in Aflac Japan which has fixed benefits and premiums. |
Internal Replacements of Insurance Contracts | 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 Accounting Policy | 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 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 | 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 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 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: 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 | 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 | 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 | 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. |
Recently Adopted Accounting Pronouncements | New Accounting Pronouncements Recently Adopted Accounting Pronouncements Standard Description Date of Adoption Effect on Financial Statements or Other Significant Matters Accounting Standards Update (ASU) 2020-04 Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting as clarified and amended by: ASU 2021-01 Reference Rate Reform (Topic 848): Relief Extended to Derivatives Impacted by Discounting Transition In March 2020, the FASB issued amendments that provide optional expedients and exceptions for applying U.S. GAAP to contracts, hedging relationships, and other transactions affected by the reference rate reform if certain criteria are met. The amendments in this ASU only apply to contracts, hedging relationships, and other transactions that reference LIBOR or another reference rate expected to be discontinued because of reference rate reform. An entity may elect to apply the amendments as of any date from the beginning of an interim period that includes or is subsequent to March 12, 2020, or prospectively from a date within an interim period that includes or is subsequent to March 12, 2020, up to the date that the financial statements are available to be issued. The amendments generally expire on December 31 2022, i.e., they do not apply to contract modifications made after December 31, 2022, new hedging relationships entered into after December 31, 2022, and hedging relationships evaluated for periods after December 31, 2022. In January 2021, the FASB issued a standard to permit entities to apply optional expedients in ASC 848 to derivative instruments modified because of discounting transition. Discounting transition refers to the changing of interest rates used for margining, discounting, or contract price alignment of derivative instruments to transition to alternative rates.The amendment is effective immediately. April 1, 2020 The adoption of the new guidance did not have an impact on the Company’s financial statements. The Company will continue to evaluate the impacts of reference rate reform on contract modifications and hedging relationships through December 31, 2022. Standard Description Date of Adoption Effect on Financial Statements or Other Significant Matters ASU 2019-04 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. 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 recent adoption of that update below. January 1, 2020 The adoption of this guidance resulted in a reclassification of $6.9 billion (at amortized cost) of pre-payable fixed-maturity securities from the held-to-maturity to the available-for-sale category. The reclassification resulted in recording in beginning 2020 accumulated other comprehensive income a net unrealized gain of $848 million on an after-tax basis, based on the securities’ fair values on the reclassification date. The reclassification impacted the adoption of ASU 2016-13 (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. January 1, 2020 The adoption of this guidance did not have a significant impact on the Company's financial position, results of operations, or disclosures. ASU 2018-16 Derivatives and Hedging Inclusion of the Secured Overnight Financing Rate (SOFR) Overnight Index Swap (OIS) Rate as a Benchmark Interest Rate for Hedge Accounting Purposes In October 2018, the FASB issued amendments to permit use of the Overnight Index Swap (OIS) rate based on the Secured Overnight Financing Rate (SOFR) as a U.S. benchmark interest rate for hedge accounting purposes under Topic 815 in addition to the Treasury obligations of the U.S. government (UST), the London Interbank Offered Rate (LIBOR) swap rate, the OIS rate based on the Fed Funds Effective Rate, and the Securities Industry and Financial Markets Association (SIFMA) Municipal Swap Rate. Early adopted as of October 1, 2018 The adoption of this guidance did not have a significant impact on the Company’s financial position, results of operations or disclosures. Standard Description Date of Adoption Effect on Financial Statements or Other Significant Matters ASU 2018-15 Intangibles - Goodwill and Other - Internal-Use Software, Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract In August 2018, the FASB issued amendments to align the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software. Early adopted as of January 1, 2019 The adoption of this guidance did not have a significant impact on the Company’s financial position, results of operations or disclosures. ASU 2018-14 Compensation - Retirement Benefits - Defined Benefit Plans - General, Disclosure Framework - Changes to the Disclosure Requirements for Defined Benefit Plans In August 2018, the FASB issued amendments to modify the disclosure requirements for employers that sponsor defined benefit pension or other postretirement plans. Accordingly, six disclosures requirements were removed, two added and two clarified. Early adopted as of December 31, 2019 The adoption of this guidance did not 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. January 1, 2020 The adoption of this guidance did not have a significant impact on the Company’s financial position, results of operations, or disclosures. ASU 2018-03 Technical Corrections and Improvements to Financial Instruments - Overall Recognition and Measurement of Financial Assets and Financial Liabilities In February 2018, the FASB issued amendments to clarify certain aspects of the guidance issued in the original Financial Instruments - Overall - Recognition and Measurement pronouncement summarized below. Specifically, for entities who have chosen the measurement alternative approach for equity securities without readily determinable fair values, the amendments clarify that entities may change from a measurement alternative approach to a fair value method through an irrevocable election that would apply to a specific equity security and all identical or similar investments of the same issuer; entities should use an observable price at the date of the transaction rather than reporting date for the measurement alternative calculation; and insurance companies should use a prospective transition method when applying the measurement alternative. Early adopted as of January 1, 2018 The adoption of this guidance did not have a significant impact on the Company’s financial position, results of operations, or disclosures. ASU 2018-02 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 (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. Standard Description Date of Adoption Effect on Financial Statements or Other Significant Matters ASU 2017-12 Derivatives and Hedging: Targeted Improvements to Accounting for Hedging Activities In August 2017, the FASB issued guidance which improves and simplifies the accounting rules around hedge accounting and creates more transparency around how economic results are presented in 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. Early adopted as of October 1, 2018 The adoption of this guidance did not have a significant impact on the Company's financial position, results of operations, or disclosures. ASU 2017-09 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. January 1, 2018 The adoption of this guidance did not have a significant impact on the Company's financial position, results of operations, or disclosures. ASU 2017-08 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. Early adopted as of July 1, 2018 The adoption of this guidance did not have a significant impact on the Company’s financial position, results of operations, or disclosures. ASU 2017-07 Compensation - Retirement Benefits: Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost 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, 2018 The adoption of this guidance did not have a significant impact on the Company's financial position, results of operations, or disclosures. Standard Description Date of Adoption Effect on Financial Statements or Other Significant Matters ASU 2017-05 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. January 1, 2018 The adoption of this guidance did not have a significant impact on the Company's financial position, results of operations, or disclosures. ASU 2017-04 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. January 1, 2020 The adoption of this guidance did not have a significant impact on the Company's financial position, results of operations, or disclosures. ASU 2017-01 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, 2018 The adoption of this guidance did not have a significant impact on the Company's financial position, results of operations, or disclosures. ASU 2016-18 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. January 1, 2018 The adoption of this guidance did not have a significant impact on the Company's financial position, results of operations, statements of cash flows, or disclosures. ASU 2016-16 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. January 1, 2018 The adoption of this guidance did not have a significant impact on the Company's financial position, results of operations, or disclosures. ASU 2016-15 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 flow classification issues, including distributions received from equity method investees. January 1, 2018 The Company elected nature of distribution for distributions received from equity method investees. The adoption of this guidance did not have a significant impact on the Company's financial position, statement of cash flows, results of operations, or disclosures. Standard Description Date of Adoption Effect on Financial Statements or Other Significant Matters ASU 2016-13 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 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 is measured in a manner similar to prior 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). January 1, 2020 The Company recorded a cumulative effect adjustment with a decrease to beginning 2020 retained earnings of $56 million, net of taxes. See Note 3 of the Notes to the Consolidated Financial Statements for credit loss disclosures. The following line items in the consolidated balance sheets were most significantly impacted by the adoption of the new accounting standard: • Fixed maturity securities held to maturity, at amortized cost • Commercial mortgage and other loans • Reinsurance recoverable, included within Other assets Standard Description Date of Adoption Effect on Financial Statements or Other Significant Matters ASU 2016-02 Leases as clarified and amended by: ASU 2018-01, Leases: Land Easement Practical Expedient for Transition to Topic 842, ASU 2018-10 , Codification Improvements to Topic 842, Leases, 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 unchanged. 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 beginning 2019 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. The adoption of the Leases Update and related amendments did not have a significant impact on the Company's financial position, results of operations, or disclosures. Standard Description Date of Adoption Effect on Financial Statements or Other Significant Matters ASU 2016-01 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. January 1, 2018 The 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. |
Description of Accounting Pronouncements Pending Adoption | Accounting Pronouncements Pending Adoption Standard Description Effect on Financial Statements or Other Significant Matters ASU 2020-01 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. 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 2018-12 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 ASU 2020-11 Financial Services - Insurance (Topic 944): Effective Date and Early Application 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. In November 2020, the FASB issued an amendment providing an additional year deferral for all insurance entities due to the impact of COVID-19. The amendments are now effective for the Company for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2022. 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 selected a modified retrospective transition method. |
Goodwill and Intangible Assets, Policy | Goodwill: Goodwill is an asset representing the future economic benefits arising from other assets acquired in a business combination that are not individually identified and separately recognized. The amount of goodwill recognized is also impacted by measurement differences resulting from certain assets and liabilities not recorded at fair value (e.g. income taxes, employee benefits). Goodwill is not amortized, but is tested for impairment at a level of a reporting unit at least annually, in the same reporting period each year. Goodwill is included in the line item “Other” assets in the consolidated balance sheets and was $269 million as of December 31, 2020, compared with $140 million at December 31, 2019. A significant majority of the goodwill balance is attributable to the following business combinations within the Aflac U.S. segment, which represents the reporting unit for goodwill impairment testing: (i) CAIC acquisition in 2009, (ii) Empowered Benefits acquisition in 2015, (iii) Argus acquisition in 2019, and (iv) acquisition of Zurich's business in the fourth quarter of 2020. |

[1] | Interest expense/income on cash flow hedges are recorded in net investment income. For interest rate swaptions classified as fair value hedges, the change in the time value of the swaptions is recognized in other comprehensive income (loss) and amortized into net investment income over its legal term. If the swaption is early terminated but the hedge item is still outstanding, the amortization of disposal amount of the swaptions is recorded in net investment income over the remaining life of the hedged items. | |||
[2] | Gains and losses on cash flow hedges and the change in the fair value of interest rate swaptions related to the time value of the swaptions in fair value hedges are recorded as unrealized gains (losses). Gains and losses on net investment hedges related to change in foreign currency spot rates are recorded in the unrealized foreign currency translation gains (losses) line in the consolidated statement of comprehensive income (loss). | |||
[3] | Impact of cash flow hedges reported as net investment gains (losses) includes an immaterial amount of gains or losses reclassified from accumulated other comprehensive income (loss) into earnings. It also includes an immaterial amount excluded from effectiveness testing during the years ended December 31, 2020, 2019 and 2018, respectively. Impact shown net of effect of hedged items (see Fair Value Hedges section of this Note 4 for further detail) |
