NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

1. BASIS OF PRESENTATION AND SIGNIFICANT EVENTS

The accompanying condensed consolidated financial statements are presented in accordance with generally accepted accounting principles for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the disclosures normally required by accounting principles generally accepted in the United States of America, or GAAP, or those normally made in an Annual Report on Form 10-K. The year-end condensed consolidated balance sheet data was derived from audited financial statements, but does not include all disclosures required by GAAP. For further information, the reader of this Form 10-Q should refer to our Form 10-K for the year ended December 31, 2018, that was filed with the Securities and Exchange Commission, or the SEC, on February 21, 2019. We refer to the Form 10-K as the “2018 Form 10-K” in this document. References throughout this document to “we,” “us,” “our,” “Company,” and “Humana” mean Humana Inc. and its subsidiaries.

The preparation of our condensed consolidated financial statements in accordance with GAAP requires us to make estimates and assumptions that affect the amounts reported in the condensed consolidated financial statements and accompanying notes. The areas involving the most significant use of estimates are the estimation of benefits payable, the impact of risk adjustment provisions related to our Medicare contracts, the valuation and related impairment recognition of investment securities, and the valuation and related impairment recognition of long-lived assets, including goodwill. These estimates are based on knowledge of current events and anticipated future events, and accordingly, actual results may ultimately differ materially from those estimates. Refer to Note 2 to the consolidated financial statements included in our 2018 Form 10-K for information on accounting policies that we consider in preparing our consolidated financial statements.

The financial information has been prepared in accordance with our customary accounting practices and has not been audited. In our opinion, the information presented reflects all adjustments necessary for a fair statement of interim results. All such adjustments are of a normal and recurring nature.

Revenue Recognition

Our revenues include premium and service revenues. Service revenues include administrative service fees that are recorded based upon established per member per month rates and the number of members for the month and are recognized as services are provided for the month. Additionally, service revenues include net patient service revenues that are recorded based upon established billing rates, less allowances for contractual adjustments, and are recognized as services are provided. For more information about our revenues, refer to Note 2 to the consolidated financial statements included in our 2018 Form 10-K for information on accounting policies that we consider in preparing our consolidated financial statements. See Note 15 for disaggregation of revenue by segment and type.

At ~~March 31,~~June 30, 2019, accounts receivable related to services were ~~$136~~$135 million. For the three and six months ended ~~March 31,~~June 30, 2019, we had no material bad-debt expense and there were no material contract assets, contract liabilities or deferred contract costs recorded on the condensed consolidated balance sheet at ~~March 31,~~June 30, 2019.

For the three and six months ended ~~March 31,~~June 30, 2019, services revenue recognized from performance obligations related to prior periods (for example, due to changes in transaction price), was not material. Further, services revenue expected to be recognized in any future year related to remaining performance obligations was not material.

Equity Method Investment in Kindred at Home

In the third quarter of 2018, we, along with TPG Capital, or TPG, and Welsh, Carson, Anderson & Stowe, or WCAS, completed the acquisitions of Kindred Healthcare, Inc., or Kindred, and privately-held Curo Health Services, or Curo, respectively, merging Curo with the hospice business of the Kindred at Home Division, or Kindred at Home. As part of these transactions, we acquired a 40% minority interest in Kindred at Home, a leading home health and hospice company, for total cash consideration of approximately $1.1 billion. ~~Earnings from Kindred at Home are included in our consolidated statement of income in the line captioned "Equity in net earnings of Kindred at Home."~~

Humana Inc.

(Unaudited)

We account for our 40% investment in Kindred at Home using the equity method of accounting. This investment is reflected as "Equity method investment in Kindred at Home" in our condensed consolidated balance sheets, with our share of income or loss reported as "Equity in net earnings of Kindred at Home" in our condensed consolidated statements of income.

We entered into a shareholders agreement with TPG and WCAS, the Sponsors, that provides for certain rights and obligations of each party. The shareholders agreement with the Sponsors includes a put option under which they have the right to require us to purchase their interest in the joint venture beginning on July 2, 2021 and ending on July 1, 2022. Likewise, we have a call option under which we have the right to require the Sponsors to sell their interest in the joint venture to Humana beginning on July 2, 2022 and ending on July 1, 2023. The put and call options, which are exercisable at a fixed EBITDA multiple and provide a minimum return on the Sponsor's investment if exercised, are measured at fair value each period using a Monte Carlo simulation. The simulation relies on assumptions around Kindred at Home's equity value, risk free interest rates, volatility, and the details specific to the put and call options. The final purchase price allocation resulted in approximately $1 billion being allocated to the investment and $236 million and $291 million allocated to the put and call options, respectively. The fair values of the put option and call option were ~~$234~~$128 million and ~~$217~~$285 million, respectively, at ~~March 31,~~June 30, 2019. The put option is included within other long-term liabilities and the call option is included within other long-term assets. The change in fair value of the put and call options is reflected as "Other ~~expense,~~income, net" in our condensed consolidated statements of income.

Health Care Reform

The Patient Protection and Affordable Care Act and The Health Care and Education Reconciliation Act of 2010 (which we collectively refer to as the Health Care Reform Law) enacted significant reforms to various aspects of the U.S. health insurance industry. Certain of these reforms became effective January 1, 2014, including an annual insurance industry premium-based fee. The Continuing Resolution bill, H.R. 195, enacted on January 22, 2018, included a one year suspension in 2019 of the health insurance industry fee, but under current law, the fee is scheduled to resume in calendar year 2020. In October 2018, we paid the federal government $1.04 billion for the annual health insurance industry fee attributed to calendar year 2018. This fee, fixed in amount by law and apportioned to insurance carriers based on market share, was not deductible for tax purposes. Each year on January 1, except when suspended, we record a liability for this fee in trade accounts payable and accrued expenses which we carry until the fee is paid. We record a corresponding deferred cost in other current assets in our condensed consolidated financial statements which is amortized ratably to expense over the calendar year. Amortization of the deferred cost was recorded in operating cost expense of approximately ~~$263~~$257 million and $520 million for the three and six months ended ~~March 31,~~June 30, 2018, respectively, resulting from the amortization of the 2018 annual health insurance industry fee.

2. RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS

In February 2016, the FASB issued new guidance related to accounting for leases which requires lessees to record assets and liabilities reflecting the leased assets and lease obligations, respectively, while following the dual model for recognition in statements of income requiring leases to be classified as either operating or finance. Operating leases will result in straight-line expense (similar to current operating leases) while finance leases will result in a front-loaded expense pattern (similar to current capital leases). We adopted the new standard effective January 1, 2019, as allowed, using the modified retrospective approach. We elected the practical expedients of not reassessing whether any expired or existing contracts are or contain leases, not reassessing the lease classification for any expired or existing leases and not reassessing any initial direct costs for existing leases. In addition, we elected the practical expedient to not separate lease and nonlease components for all of our asset classes. We made a permitted accounting policy election to not apply the new guidance to leases with an initial term of 12 months or less. We ~~will~~ recognize those lease payments in the condensed consolidated statement of income on a straight-line basis over the lease term. As of January 1, 2019, the adoption of the standard resulted in recognition of right-of-use, or ROU, liabilities of approximately $470 million and ROU assets of $436 million, which equals the ROU liabilities net of accrued rent and lease incentives. The standard does not materially affect our results of operations, cash flows and liquidity. See Note 8 for further information.

In June 2016, the FASB issued guidance introducing a new model for recognizing credit losses on financial instruments based on an estimate of current expected credit losses. The guidance is effective for us beginning January

Humana Inc.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

(Unaudited)

1, 2020. The new current expected credit losses (CECL) model generally calls for the immediate recognition of all expected credit losses and applies to loans, accounts and trade receivables as well as other financial assets measured at amortized cost, loan commitments and off-balance sheet credit exposures, debt securities and other financial assets measured at fair value through other comprehensive income, and beneficial interests in securitized financial assets. The new guidance replaces the current incurred loss model for measuring expected credit losses, requires expected losses on available for sale debt securities to be recognized through an allowance for credit losses rather than as reductions in the amortized cost of the securities, and provides for additional disclosure requirements. Our investment portfolio consists of available for sale debt securities. We are in the process of identifying and analyzing financial assets measured at amortized cost balances that are in scope of the new CECL model. We are currently evaluating the impact on our results of operations, financial condition, and cash flows.

In March 2017, the FASB issued new guidance that amends the accounting for premium amortization on purchased callable debt securities by shortening the amortization period. This amended guidance requires the premium to be amortized to the earliest call date instead of maturity date. The new guidance is effective for us beginning with annual and interim periods in 2019. This guidance did not have a material impact on our results of operations, financial condition or cash flows.

In September 2018, the FASB issued new guidance related to accounting for long-duration contracts of insurers which revises key elements of the measurement models and disclosure requirements for long-duration contracts issued by insurers and reinsurers. The new guidance is effective for us beginning with annual and interim periods in 2021, with earlier adoption permitted, and requires retrospective application to previously issued annual and interim financial statements. We are currently evaluating the impact on our results of operations, financial position and cash flows.

There are no other recently issued accounting standards that apply to us or that are expected to have a material impact on our results of operations, financial condition, or cash flows.

3. ACQUISITIONS AND DIVESTITURES

Sale of Closed Block of Commercial Long-Term Care Insurance Business

In the third quarter of 2018, we completed the sale of our wholly-owned subsidiary, KMG America Corporation, or KMG, to Continental General Insurance Company, or CGIC, a Texas-based insurance company wholly owned by HC2 Holdings, Inc., a diversified holding company. KMG's subsidiary, Kanawha Insurance Company, or KIC, included our closed block of non-strategic commercial long-term care policies. Upon closing, we funded the transaction with approximately $190 million of parent company cash contributed into KMG, subject to customary adjustments, in addition to the transfer of approximately $160 million of statutory capital with the sale.

In connection with the sale of KMG, we recognized a pretax loss, including transaction costs, of $786 million and a corresponding $452 million income tax benefit.

Also, in the third quarter of 2018, we entered into reinsurance contracts to transfer the risk associated with certain voluntary benefit and financial protection products previously issued primarily by KIC to a third party. We transferred approximately $245 million of cash to the third party and recorded a commensurate reinsurance recoverable as a result of these transactions. The reinsurance recoverable was included as part of the net assets disposed. There was no material impact to operating results from these reinsurance transactions.

KMG revenues for the three and six months ended ~~March 31,~~June 30, 2018 were ~~$79 million. For the three months ended March 31, 2018~~$93 million and $172 million, respectively. KMG pretax income ~~was $18 million.~~for the three and six months ended June 30, 2018 were $35 million and $53 million, respectively.

Other Acquisitions and Divestitures

In the first quarter of 2018, we acquired the remaining equity interest in MCCI Holdings, LLC, or MCCI, a privately held management service organization headquartered in Miami, Florida, that primarily coordinates medical care for Medicare Advantage beneficiaries in Florida and Texas. The purchase price consisted primarily of $169 million cash, as well as our existing investment in MCCI and a note receivable and a revolving note with an aggregate balance of $383 million. This resulted in a purchase price allocation to goodwill of $483 million, other intangible assets of $80 million, and net tangible assets of $24 million. The goodwill was assigned to the Retail and Healthcare Services segments. The other intangible assets, which primarily consist of customer contracts, have an estimated weighted average useful life of 8 years. Goodwill and other intangible assets are amortizable as deductible expenses for tax purposes.

In the second quarter of 2018, we acquired Family Physicians Group, or FPG, for cash consideration of approximately $185 million, net of cash received. FPG serves Medicare Advantage and Managed Medicaid HMO patients in Greater Orlando, Florida with a footprint that includes clinics located in Lake, Orange, Osceola and Seminole counties. This resulted in a purchase price allocation to goodwill of $133 million, other intangible assets of $38 million and net tangible assets of $14 million. The goodwill was assigned to the Retail and Healthcare Services segments. The other intangible assets, which primarily consist of customer contracts, have an estimated weighted average useful life of 4.9 years. The purchase price allocations for MCCI and FPG are final.

During 2019 and 2018, we acquired other health and wellness related businesses which, individually or in the aggregate, have not had a material impact on our results of operations, financial condition, or cash flows. The results of operations and financial condition of these businesses have been included in our condensed consolidated statements of income and condensed consolidated balance sheets from the respective acquisition dates. Acquisition-related costs recognized in 2019 and 2018 were not material to our results of operations. The pro forma financial information assuming the acquisitions had occurred as of the beginning of the calendar year prior to the year of acquisition, as well as the revenues and earnings generated during the year of acquisition, were not material for disclosure purposes.

individual state exceeding ~~12%~~16%. Our investment policy limits investments in a single issuer and requires diversification among various asset types.

Our unrealized losses from all securities were generated from approximately ~~690~~330 positions out of a total of approximately ~~1,430~~1,460 positions at ~~March 31,~~June 30, 2019. All issuers of securities we own that were trading at an unrealized loss at ~~March 31,~~June 30, 2019 remain current on all contractual payments. After taking into account these and other factors previously described, we believe these unrealized losses primarily were caused by an increase in market interest rates in the current markets since the time the securities were purchased. At ~~March 31,~~June 30, 2019, we did not intend to sell the securities with an unrealized loss position in accumulated other comprehensive income, and it is not likely that we will be required to sell these securities before recovery of their amortized cost basis. As a result, we believe that the securities with an unrealized loss were not other-than-temporarily impaired at ~~March 31,~~June 30, 2019.

The detail of realized gains (losses) related to investment securities and included within investment income was as follows for the three and six months ended ~~March 31,~~June 30, 2019 and 2018:

Financial Liabilities

Our debt is recorded at carrying value in our consolidated balance sheets. The carrying value of our senior notes debt outstanding, net of unamortized debt issuance costs, was $4,776 million at ~~March 31,~~June 30, 2019 and $4,774 million at December 31, 2018. The fair value of our senior notes debt was ~~$5,006~~$5,115 million at ~~March 31,~~June 30, 2019 and $5,191 million at December 31, 2018. The fair value of our long-term debt is determined based on Level 2 inputs, including quoted market prices for the same or similar debt, or if no quoted market prices are available, on the current prices estimated to be available to us for debt with similar terms and remaining maturities. Due to the short-term nature, carrying value approximates fair value for our term note and commercial paper borrowings. The term loan outstanding and commercial paper borrowings were ~~$1,318~~$950 million as of ~~March 31,~~June 30, 2019 and $1,295 million as of December 31, 2018.

~~OtherAssets~~Other Assets and Liabilities Measured at Fair Value

As disclosed in Note 3, we acquired MCCI and FPG during 2018. The values of net tangible assets acquired and the resulting goodwill and other intangible assets were recorded at fair value using Level 3 inputs. The majority of the tangible assets acquired and liabilities assumed were recorded at their carrying values as of the respective dates of acquisition, as their carrying values approximated their fair values due to their short-term nature. The fair values of goodwill and other intangible assets acquired in these acquisitions were internally estimated primarily based on the income approach. The income approach estimates fair value based on the present value of the cash flows that the assets are expected to generate in the future. We developed internal estimates for the expected future cash flows and discount rates used in the present value calculations. Other than assets acquired and liabilities assumed in these acquisitions, and the put option liability and call option asset associated with our investment in Kindred at Home as detailed in Note 2,1, there were no other material assets or liabilities measured at fair value on a recurring or nonrecurring basis during 2019 or 2018.

6. MEDICARE PART D

We cover prescription drug benefits in accordance with Medicare Part D under multiple contracts with the Centers for Medicare and Medicaid Services, or CMS, as described further in Note 2 to the consolidated financial statements included in our 2018 Form 10-K. The accompanying condensed consolidated balance sheets include the following amounts associated with Medicare Part D at ~~March 31,~~June 30, 2019 and December 31, 2018. CMS subsidies/discounts in the table below include the reinsurance and low-income cost subsidies funded by CMS for which we assume no risk as well as brand name prescription drug discounts for Part D plan participants in the coverage gap funded by CMS and pharmaceutical manufacturers.

8. LEASES

2019

We determine if a contract contains a lease by evaluating the nature and substance of the agreement. We lease facilities, computer hardware, and other furniture and equipment. Leases with an initial term of 12 months or less are not recorded on the balance sheet; we recognize lease expense for these leases on a straight-line basis over the lease term. For new lease agreements, we combine lease and nonlease components for all of our asset classes. See Note 2 for further information.

When portions of the lease payments are not fixed or depend on an index or rate, we consider those payments to be variable in nature. These include, but are not limited to, common area maintenance, taxes and insurance. Variable lease payments are recorded in the period in which the obligation for the payment is incurred.

Most leases include options to renew, with renewal terms that can extend the lease term. The exercise of lease renewal options is at our sole discretion. Certain leases also include options to purchase the leased property. The depreciable life of assets and leasehold improvements are limited by the expected lease term, unless there is a transfer of title or purchase option reasonably certain of exercise. Our lease agreements do not contain any material residual value guarantees or material restrictive covenants.

At ~~March 31,~~June 30, 2019, ~~$416~~$406 million of operating ROU assets are included within other long-term assets in our condensed consolidated balance sheet. Additionally, at ~~March 31,~~June 30, 2019, ~~$122~~$121 million and ~~$328~~$324 million of operating ROU lease liabilities are included within trade accounts payable and accrued expenses and other long-term liabilities, respectively, in our condensed consolidated balance sheet based on the remaining lease term.

For the three and six months ended ~~March 31,~~June 30, 2019, total fixed operating lease costs, excluding short-term lease costs, were $39 million and $78 million, respectively, and are included within operating costs in our condensed consolidated statement of income. Short-term lease costs were not material. In addition, for the three and six months ended June 30, 2019, total variable operating lease costs were ~~$16~~$19 million and $35 million, respectively and are included within operating costs in our condensed consolidated statement of income. We sublease facilities or partial facilities to third party tenants for space not used in our operations. For the three and six months ended ~~March 31,~~June 30, 2019, sublease rental income was $9$10 million and $19 million, respectively, and is included within operating costs in our condensed consolidated statement of income.

The weighted average remaining lease term is 4.8 years with a weighted average discount rate of 4.3% at ~~March 31,~~June 30, 2019. For the ~~three~~six months ended ~~March 31,~~June 30, 2019, cash paid for amounts included in the measurement of lease liabilities included within our operating cash flows was ~~$39~~$75 million.

(Unaudited)

As most of our leases do not provide an implicit rate, we use our incremental borrowing rate, as adjusted for collateralized borrowings, based on the information available at date of adoption or commencement date in determining the present value of lease payments.

For the year ended 2018, under prior lease disclosure requirements

We lease facilities, computer hardware, and other furniture and equipment under long-term operating leases that are ~~noncancelable~~non-cancelable and expire on various dates through 2046. We sublease facilities or partial facilities to third party tenants for space not used in our operations. Rent with scheduled escalation terms are accounted for on a straight-line basis over the lease term. Rent expense and sublease rental income, which are recorded net as an operating cost, for all operating leases were as follows for the years ended December 31, 2018, 2017 and 2016:

Amounts incurred related to prior periods vary from previously estimated liabilities as the claims ultimately are settled. Negative amounts reported for incurred related to prior years result from claims being ultimately settled for amounts less than originally estimated (favorable development).

Our reserving practice is to consistently recognize the actuarial best estimate of our ultimate liability for claims. Actuarial standards require the use of assumptions based on moderately adverse experience, which generally results in favorable reserve development, or reserves that are considered redundant.

Benefits expense excluded from the previous table related to our long duration policies was as follows for the ~~three~~six months ended ~~March 31,~~June 30, 2019 and 2018. The Other Businesses category was related to our closed-block of commercial long-term care insurance policies, which were sold in 2018. We also exited our Individual Commercial business beginning January 1, 2018.

privately-negotiated transactions, including pursuant to accelerated share repurchase agreements with investment banks, subject to certain regulatory restrictions on volume, pricing, and timing.

On December 14, 2017, our Board of Directors authorized the repurchase of up to $3.0 billion of our common shares expiring on December 31, 2020, exclusive of shares repurchased in connection with employee stock plans.

On November 28, 2018, we entered into an accelerated stock repurchase agreement, the November 2018 ASR, with Goldman Sachs to repurchase $750 million of our common stock as part of the $3.0 billion share repurchase program authorized by the Board of Directors on December 14, 2017. On November 29, 2018, we made a payment of $750 million to Goldman Sachs from available cash on hand and received an initial delivery of 1.94 million shares of our common stock from Goldman Sachs. The payment to Goldman Sachs was recorded as a reduction to stockholders’ equity, consisting of a $600 million increase in treasury stock, which reflects the value of the initial 1.94 million shares received upon initial settlement, and a $150 million decrease in capital in excess of par value, which reflected the value of stock held back by Goldman Sachs pending final settlement of the November 2018 ASR. Upon final settlement of the November 2018 ASR on February 28, 2019, we received an additional 0.6 million shares as determined by the average daily volume weighted-averages share price of our common stock during the term of the agreement of $295.15, bringing the total shares received under this program to 2.54 million. In addition, upon settlement we reclassified the $150 million value of stock initially held back by Goldman Sachs from capital in excess of par value to treasury stock.

~~Our remaining~~On July 30, 2019, the Board of Directors replaced a previous share repurchase authorization ~~was~~of up to $3 billion (of which approximately ~~$1.0~~$1.03 billion remained unused) with a new authorization for repurchases of up to $3 billion of ~~the $3.0 billion share repurchase program as~~our common shares exclusive of ~~May 1, 2019.~~shares repurchased in connection with employee stock plans, expiring on June 30, 2022.

In connection with employee stock plans, we acquired ~~0.03 million~~34 thousand common shares for $10 million and ~~0.19~~0.3 million common shares for ~~$51~~$69 million during the ~~three~~six months ended ~~March 31,~~June 30, 2019 and 2018, respectively.

The effective income tax rate was ~~24.4%~~24.3% for the ~~three~~six months ended ~~March 31,~~June 30, 2019 compared to ~~30.7%~~5.8% for the ~~three~~six months ended ~~March 31,~~June 30, 2018, primarily due to the impact of the ~~temporary~~ suspension of the non-deductible health insurance industry fee in 2019 as well as the deferred tax benefit recognized in 2018 from the loss on sale of KMG. The effective income tax rate was 24.2% for the three months ended June 30, 2019. The effective income tax rate for the three months ended June 30, 2018 reflects a $430 million deferred tax benefit recorded during the three months ended June 30, 2018, resulting from the loss on the sale of KMG attributable to its original tax basis and subsequent capital contributions to fund accumulated losses.

Credit Agreement

Our 5-year, $2.0 billion unsecured revolving credit agreement expires May 2022. Under the credit agreement, at our option, we can borrow on either a competitive advance basis or a revolving credit basis. The revolving credit portion bears interest at either LIBOR plus a spread or the base rate plus a spread. The LIBOR spread, currently 110.0 basis points, varies depending on our credit ratings ranging from 91.0 to 150.0 basis points. We also pay an annual facility fee regardless of utilization. This facility fee, currently 15.0 basis points, may fluctuate between 9.0 and 25.0 basis points, depending upon our credit ratings. The competitive advance portion of any borrowings will bear interest at market rates prevailing at the time of borrowing on either a fixed rate or a floating rate based on LIBOR, at our option.

The terms of the credit agreement include standard provisions related to conditions of borrowing which could limit our ability to borrow additional funds. In addition, the credit agreement contains customary restrictive covenants and a financial covenant regarding maximum debt to capitalization of 50%, as well as customary events of default. We are in compliance with this financial covenant, with actual debt to capitalization of ~~36.0%~~32.5% as measured in accordance with the credit agreement as of ~~March 31,~~June 30, 2019. Upon our agreement with one or more financial institutions, we may expand

Humana Inc.

the aggregate commitments under the credit agreement to a maximum of $2.5 billion, through a ~~$500.0~~$500 million incremental loan facility.

At ~~March 31,~~June 30, 2019, we had no borrowings and no letters of credit outstanding under the credit agreement. Accordingly, as of ~~March 31,~~June 30, 2019, we had $2.0 billion of remaining borrowing capacity (which excludes the uncommitted $500 million incremental loan facility under the credit agreement), none of which would be restricted by our financial covenant compliance requirement. We have other customary, arms-length relationships, including financial advisory and banking, with some parties to the credit agreement.

Commercial Paper

Under our commercial paper program we may issue short-term, unsecured commercial paper notes privately placed on a discount basis through certain broker dealers at any time not to exceed $2 billion. Amounts available under the program may be borrowed, repaid and re-borrowed from time to time. The net proceeds of issuances have been and are expected to be used for general corporate purposes. The maximum principal amount outstanding at any one time during the ~~three~~six months ended ~~March 31,~~June 30, 2019 was ~~$801~~$670 million, with ~~$669~~$300 million outstanding at ~~March 31,~~June 30, 2019 compared to $645 million outstanding at December 31, 2018. The outstanding commercial paper at ~~March 31,~~June 30, 2019 had a weighted average annual interest rate of ~~3.03%~~2.85%.

Term Note

In November 2018, we entered into a $1.0 billion term note agreement with a bank at a variable rate of interest due within one year. We may elect to incur interest at either the bank's base rate or LIBOR plus 115 basis points. The base rate is defined as the higher of the daily federal funds rate plus 50 basis points; or the bank's prime rate; or LIBOR plus 100 basis points. The interest rate in effect at ~~March 31,~~June 30, 2019 was ~~3.65%~~3.55%. The note is prepayable without penalty. ~~Proceeds were primarily used to fund the November 2018 accelerated stock repurchase agreement.~~ We repaid $350 million prior to December 31, 2018. The term note shares the customary terms and provisions as well as financial covenants of our Credit Agreement, as discussed above.

14. COMMITMENTS, GUARANTEES AND CONTINGENCIES

Government Contracts

Our Medicare products, which accounted for approximately 82% of our total premiums and services revenue for the ~~three~~six months ended ~~March 31,~~June 30, 2019, primarily consisted of products covered under the Medicare Advantage and Medicare Part D Prescription Drug Plan contracts with the federal government. These contracts are renewed generally for a calendar year term unless CMS notifies us of its decision not to renew by May 1 of the calendar year in which the contract would end, or we notify CMS of our decision not to renew by the first Monday in June of the calendar

~~Humana Inc.~~

~~NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS—(Continued)~~

~~(Unaudited)~~

year in which the contract would end. All material contracts between Humana and CMS relating to our Medicare products have been renewed for ~~2019, and all of our~~2020. Our product offerings ~~filed with~~under those contracts are subject to approval by CMS ~~for 2019 have been approved.~~in the third quarter of 2019.

CMS uses a risk-adjustment model which adjusts premiums paid to Medicare Advantage, or MA, plans according to health status of covered members. The risk-adjustment model, which CMS implemented pursuant to the Balanced Budget Act of 1997 (BBA) and the Benefits Improvement and Protection Act of 2000 (BIPA), generally pays more where a plan's membership has higher expected costs. Under this model, rates paid to MA plans are based on actuarially determined bids, which include a process whereby our prospective payments are based on our estimated cost of providing standard Medicare-covered benefits to an enrollee with a "national average risk profile." That baseline payment amount is adjusted to reflect the health status of our enrolled membership. Under the risk-adjustment methodology, all MA plans must collect and submit the necessary diagnosis code information from hospital inpatient, hospital outpatient, and physician providers to CMS within prescribed deadlines. The CMS risk-adjustment model uses the diagnosis data to calculate the risk-adjusted premium payment to MA plans, which CMS adjusts for coding pattern differences between the health plans and the government fee-for-service program. We generally rely on providers, including certain providers in our network who are our employees, to code their claim submissions with appropriate diagnoses, which we send to CMS as the basis for our payment received from CMS under the actuarial risk-adjustment model. We also rely on these

Humana Inc.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

(Unaudited)

providers to document appropriately all medical data, including the diagnosis data submitted with claims. In addition, we conduct medical record reviews as part of our data and payment accuracy compliance efforts, to more accurately reflect diagnosis conditions under the risk adjustment model. These compliance efforts include the internal contract level audits described in more detail below, as well as ordinary course reviews of our internal business processes.

CMS is phasing-in the process of calculating risk scores using diagnoses data from the Risk Adjustment Processing System, or RAPS, to diagnoses data from the Encounter Data System, or EDS. The RAPS process requires MA plans to apply a filter logic based on CMS guidelines and only submit diagnoses that satisfy those guidelines. For submissions through EDS, CMS requires MA plans to submit all the encounter data and CMS will apply the risk adjustment filtering logic to determine the risk scores. For 2018, 15% of the risk score was calculated from claims data submitted through EDS. In 2019 and 2020 CMS will increase that percentage to 25% and 50%, respectively. The phase-in from RAPS to EDS could result in different risk scores from each dataset as a result of plan processing issues, CMS processing issues, or filtering logic differences between RAPS and EDS, and could have a material adverse effect on our results of operations, financial position, or cash flows.

CMS and the Office of the Inspector General of Health and Human Services, or HHS-OIG, are continuing to perform audits of various companies’ selected MA contracts related to this risk adjustment diagnosis data. We refer to these audits as Risk-Adjustment Data Validation Audits, or RADV audits. RADV audits review medical records in an attempt to validate provider medical record documentation and coding practices which influence the calculation of premium payments to MA plans.

In 2012, CMS released a “Notice of Final Payment Error Calculation Methodology for Part C Medicare Advantage Risk Adjustment Data Validation (RADV) Contract-Level Audits.” The payment error calculation methodology provided that, in calculating the economic impact of audit results for an MA contract, if any, the results of the RADV audit sample would be extrapolated to the entire MA contract after a comparison of the audit results to a similar audit of the government’s traditional fee-for-service Medicare program, or Medicare FFS. We refer to the process of accounting for errors in FFS claims as the "FFS Adjuster." This comparison of RADV audit results to the FFS error rate is necessary to determine the economic impact, if any, of RADV audit results because the government used the Medicare FFS program data set, including any attendant errors that are present in that data set, to estimate the costs of various health status conditions and to set the resulting adjustments to MA plans’ payment rates in order to establish actuarial equivalence in payment rates as required under the Medicare statute. CMS already makes other adjustments to payment rates based on a comparison of coding pattern differences between MA plans and Medicare FFS data (such as for frequency of coding for certain diagnoses in MA plan data versus the Medicare FFS program dataset).

The final RADV extrapolation methodology, including the first application of extrapolated audit results to determine audit settlements, is expected to be applied to CMS RADV contract level audits conducted for contract year 2011 and

~~Humana Inc.~~

~~NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS—(Continued)~~

~~(Unaudited)~~

subsequent years. CMS is currently conducting RADV contract level audits for certain of our Medicare Advantage plans.

Estimated audit settlements are recorded as a reduction of premiums revenue in our consolidated statements of income, based upon available information. We perform internal contract level audits based on the RADV audit methodology prescribed by CMS. Included in these internal contract level audits is an audit of our Private Fee-For Service business which we used to represent a proxy of the FFS Adjuster which has not yet been finalized. We based our accrual of estimated audit settlements for each contract year on the results of these internal contract level audits and update our estimates as each audit is completed. Estimates derived from these results were not material to our results of operations, financial position, or cash flows. We report the results of these internal contract level audits to CMS, including identified overpayments, if any.

On October 26, 2018, CMS issued a proposed rule and accompanying materials (which we refer to as the “Proposed Rule”) related to, among other things, the RADV audit methodology described above. If implemented, the Proposed Rule would use extrapolation in RADV audits applicable to payment year 2011 contract-level audits and all subsequent audits, without the application of a FFS Adjuster to audit findings. We are studying the Proposed Rule and CMS’ underlying analysis contained therein. We believe, however, that the Proposed Rule fails to address adequately the statutory requirement of actuarial equivalence, and we expect to provide substantive comments to CMS on the Proposed

Humana Inc.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

(Unaudited)

Rule as part of the notice-and-comment rulemaking process. We are also evaluating the potential impact of the Proposed Rule, and any related regulatory, industry or company reactions, all or any of which could have a material adverse effect on our results of operations, financial position, or cash flows.

In addition, as part of our internal compliance efforts, we routinely perform ordinary course reviews of our internal business processes related to, among other things, our risk coding and data submissions in connection with the risk- adjustment model. These reviews may also result in the identification of errors and the submission of corrections to CMS, that may, either individually or in the aggregate, be material. As such, the result of these reviews may have a material adverse effect on our results of operations, financial position, or cash flows.

We believe that CMS' statements and policies regarding the requirement to report and return identified overpayments received by MA plans are inconsistent with CMS' 2012 RADV audit methodology, and the Medicare statute's requirements. These statements and policies, such as certain statements contained in the preamble to CMS’ final rule release regarding Medicare Advantage and Part D prescription drug benefit program regulations for Contract Year 2015 (which we refer to as the "Overpayment Rule"), and the Proposed Rule, appear to equate each Medicare Advantage risk adjustment data error with an “overpayment” without addressing the principles underlying the FFS Adjuster referenced above. On September 7, 2018, the Federal District Court for the District of Columbia vacated CMS's Overpayment Rule, concluding that it violated the Medicare statute, including the requirement for actuarial equivalence, and that the Overpayment Rule was also arbitrary and capricious in departing from CMS's RADV methodology without adequate explanation (among other reasons). CMS has filed a motion for reconsideration related to certain aspects of the Federal District Court's opinion and has simultaneously filed a notice to appeal the decision to the Circuit Court of Appeals.

We will continue to work with CMS to ensure that MA plans are paid accurately and that payment model principles are in accordance with the requirements of the Social Security Act, which, if not implemented correctly could have a material adverse effect on our results of operations, financial position, or cash flows.

At ~~March 31,~~June 30, 2019, our military services business, which accounted for approximately 1% of our total premiums and services revenue for the ~~three~~six months ended ~~March 31,~~June 30, 2019, primarily consisted of the TRICARE T2017 East Region contract. The T2017 East Region contract is a consolidation of the former T3 North and South Regions, comprising thirty-two states and approximately 6 million TRICARE beneficiaries, under which delivery of health care services commenced on January 1, 2018. The T2017 East Region contract is a 5-year contract set to expire on December 31, 2022 and is subject to renewals on January 1 of each year during its term at the government's option.

Our state-based Medicaid business accounted for approximately 4% of our total premiums and services revenue for the ~~three~~six months ended ~~March 31,~~June 30, 2019. In addition to our state-based Temporary Assistance for Needy Families,

The loss of any of the contracts above or significant changes in these programs as a result of legislative or regulatory action, including reductions in premium payments to us, regulatory restrictions on profitability, including reviews by regulatory bodies that may compare our Medicare Advantage profitability to our non-Medicare Advantage business profitability, or compare the profitability of various products within our Medicare Advantage business, and require that they remain within certain ranges of each other, or increases in member benefits or member eligibility criteria without corresponding increases in premium payments to us, may have a material adverse effect on our results of operations, financial position, and cash flows.

Legal Proceedings and Certain Regulatory Matters

As previously disclosed, the Civil Division of the United States Department of Justice provided us with an information request in December 2014, concerning our Medicare Part C risk adjustment practices. The request relates to our oversight and submission of risk adjustment data generated by providers in our Medicare Advantage network, as well as to our business and compliance practices related to risk adjustment data generated by our providers and by us, including medical record reviews conducted as part of our data and payment accuracy compliance efforts, the use of health and well-being assessments, and our fraud detection efforts. We believe that this request for information is in connection with a wider review of Medicare Risk Adjustment generally that includes a number of Medicare Advantage plans, providers and vendors. We continue to cooperate with and voluntarily respond to the information requests from the Department of Justice. These matters are expected to result in additional qui tam litigation.

As previously disclosed, on January 19, 2016, an individual filed a qui tam suit captioned United States of America ex rel. Steven Scott v. Humana, Inc., in United States District Court, Central District of California, Western Division. The complaint alleges certain civil violations by us in connection with the actuarial equivalence of the plan benefits under Humana’s Basic PDP plan, a prescription drug plan offered by us under Medicare Part D. The action seeks damages and penalties on behalf of the United States under the False Claims Act. The court ordered the qui tam action unsealed on September 13, 2017, so that the relator could proceed, following notice from the U.S. Government that it was not intervening at that time. On January 29, 2018, the suit was transferred to the United States District Court, Western District of Kentucky, Louisville Division. We take seriously our obligations to comply with applicable CMS requirements and actuarial standards of practice, and continue to vigorously defend against these allegations since the transfer to the Western District of Kentucky. We have engaged in active discovery with the relator who has ~~pursed~~pursued the matter on behalf of the United States ~~for the past year,~~following its unsealing, and expect that discovery process to conclude in the near future and for the Court to consider our motion for summary judgment.

On November 2, 2017, we filed suit against the United States of America in the United States Court of Federal Claims, on behalf of our health plans seeking recovery from the federal government of approximately $611 million in payments under the risk corridor premium stabilization program established under Health Care Reform, for years 2014, 2015 and 2016. Our case has been stayed by the Court, pending resolution of similar cases filed by other insurers. We have not recognized revenue, nor have we recorded a receivable, for any amount due from the federal government for unpaid risk corridor payments as of ~~March 31,~~June 30, 2019. We have fully recognized all liabilities due to the federal government that we have incurred under the risk corridor program, and have paid all amounts due to the federal government as required. There is no assurance that we will prevail in the lawsuit.

Other Lawsuits and Regulatory Matters

Our current and past business practices are subject to review or other investigations by various state insurance and health care regulatory authorities and other state and federal regulatory authorities. These authorities regularly scrutinize the business practices of health insurance, health care delivery and benefits companies. These reviews focus on numerous facets of our business, including claims payment practices, statutory capital requirements, provider contracting, risk adjustment, competitive practices, commission payments, privacy issues, utilization management practices, pharmacy benefits, access to care, and sales practices, among others. Some of these reviews have historically resulted in fines imposed on us and some have required changes to some of our practices. We continue to be subject to these reviews, which could result in additional fines or other sanctions being imposed on us or additional changes in some of our practices.

We also are involved in various other lawsuits that arise, for the most part, in the ordinary course of our business

operations, certain of which may be styled as class-action lawsuits. Among other matters, this litigation may include employment matters, claims of medical malpractice, bad faith, nonacceptance or termination of providers, anticompetitive practices, improper rate setting, provider contract rate and payment disputes, including disputes over reimbursement rates required by statute, general contractual matters, intellectual property matters, and challenges to subrogation practices. Under state guaranty assessment laws, including those related to state cooperative failures in the industry, we may be assessed (up to prescribed limits) for certain obligations to the policyholders and claimants of insolvent insurance companies that write the same line or lines of business as we do.

Humana Inc.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

(Unaudited)

As a government contractor, we may also be subject to qui tam litigation brought by individuals who seek to sue on behalf of the government, alleging that the government contractor submitted false claims to the government including, among other allegations, those resulting from coding and review practices under the Medicare risk adjustment model. Qui tam litigation is filed under seal to allow the government an opportunity to investigate and to decide if it wishes to intervene and assume control of the litigation. If the government does not intervene, the individual may continue to prosecute the action on his or her own, on behalf of the government. We also are subject to other allegations of non-performance of contractual obligations to providers, members, and others, including failure to properly pay claims, improper policy terminations, challenges to our implementation of the Medicare Part D prescription drug program and other litigation.

A limited number of the claims asserted against us are subject to insurance coverage. Personal injury claims, claims for extra contractual damages, care delivery malpractice, and claims arising from medical benefit denials are covered by insurance from our wholly owned captive insurance subsidiary and excess carriers, except to the extent that claimants seek punitive damages, which may not be covered by insurance in certain states in which insurance coverage for punitive damages is not permitted. In addition, insurance coverage for all or certain forms of liability has become increasingly costly and may become unavailable or prohibitively expensive in the future.

We record accruals for the contingencies discussed in the sections above to the extent that we conclude it is probable that a liability has been incurred and the amount of the loss can be reasonably estimated. No estimate of the possible loss or range of loss in excess of amounts accrued, if any, can be made at this time regarding the matters specifically described above because of the inherently unpredictable nature of legal proceedings, which also may be exacerbated by various factors, including: (i) the damages sought in the proceedings are unsubstantiated or indeterminate; (ii) discovery is not complete; (iii) the proceeding is in its early stages; (iv) the matters present legal uncertainties; (v) there are significant facts in dispute; (vi) there are a large number of parties (including where it is uncertain how liability, if any, will be shared among multiple defendants); or (vii) there is a wide range of potential outcomes.

The outcome of any current or future litigation or governmental or internal investigations, including the matters described above, cannot be accurately predicted, nor can we predict any resulting judgments, penalties, fines or other sanctions that may be imposed at the discretion of federal or state regulatory authorities or as a result of actions by third parties. Nevertheless, it is reasonably possible that any such outcome of litigation, judgments, penalties, fines or other sanctions could be substantial, and the outcome of these matters may have a material adverse effect on our results of operations, financial position, and cash flows, and may also affect our reputation.

15. SEGMENT INFORMATION

We manage our business with three reportable segments: Retail, Group and Specialty, and Healthcare Services. ~~In addition,~~Beginning January 1, 2018, we exited the individual commercial fully-insured medical health insurance business, as well as certain other business, and therefore no longer report separately the Individual Commercial segment and the Other Business category in the current year. Previously, the Other Business category included businesses that were not individually reportable because they did not meet the quantitative thresholds required by generally accepted accounting ~~principles. We exited the individual~~principles, primarily our closed-block of commercial ~~fully-insured medical health~~long-term care insurance ~~business beginning January 1, 2018, as well as certain other business, and therefore no longer report separately the Individual Commercial segment and the Other Business category~~policies which were sold in ~~the current year.~~2018. These segments are based on a combination of the type of health plan customer and adjacent businesses centered on well-being solutions for our health plans and other customers, as described below. These segment groupings are consistent with information used by our Chief Executive Officer, the Chief Operating Decision Maker, to assess performance and allocate resources.

care service, such as home health and other services and capabilities to promote wellness and advance population health, including our minority investment in Kindred at Home. We reported under the category of Other Businesses those businesses that did not align with the reportable segments described above, primarily our closed-block long-term care insurance policies, which were sold in 2018.

Our Healthcare Services intersegment revenues primarily relate to managing prescription drug coverage for members of our other segments through Humana Pharmacy Solutions®, or HPS, and includes the operations of Humana Pharmacy, Inc., our mail order pharmacy business. These revenues consist of the prescription price (ingredient cost plus dispensing fee), including the portion to be settled with the member (co-share) or with the government (subsidies), plus any associated administrative fees. Services revenues related to the distribution of prescriptions by third party retail pharmacies in our networks are recognized when the claim is processed and product revenues from dispensing prescriptions from our mail order pharmacies are recorded when the prescription or product is shipped. Our pharmacy operations, which are responsible for designing pharmacy benefits, including defining member co-share responsibilities, determining formulary listings, contracting with retail pharmacies, confirming member eligibility, reviewing drug utilization, and processing claims, act as a principal in the arrangement on behalf of members in our other segments. As principal, our Healthcare Services segment reports revenues on a gross basis, including co-share amounts from members collected by third party retail pharmacies at the point of service.

In addition, our Healthcare Services intersegment revenues include revenues earned by certain owned providers derived from risk-based and non-risk-based managed care agreements with our health plans. Under ~~risk based~~risk-based agreements, the provider receives a monthly capitated fee that varies depending on the demographics and health status of the member, for each member assigned to these owned providers by our health plans. The owned provider assumes the economic risk of funding the assigned members’ healthcare services. Under non risk-based agreements, our health plans retain the economic risk of funding the assigned members' healthcare services. Our Healthcare Services segment reports provider services revenues associated with risk-based agreements on a gross basis, whereby capitation fee revenue is recognized in the period in which the assigned members are entitled to receive healthcare services. Provider services revenues associated with non-risk-based agreements are presented net of associated healthcare costs.

We present our condensed consolidated results of operations from the perspective of the health plans. As a result, the cost of providing benefits to our members, whether provided via a third party provider or internally through a stand-alone subsidiary, is classified as benefits expense and excludes the portion of the cost for which the health plans do not bear responsibility, including member co-share amounts and government subsidies of ~~$3.1~~$3.6 billion and ~~$2.9~~$3.3 billion for the three months ended ~~March 31,~~June 30, 2019 and 2018, respectively. For the six months ended June 30, 2019 and 2018 these amounts were $6.7 billion and $6.2 billion, respectively. In addition, depreciation and amortization expense associated with certain businesses in our Healthcare Services segment delivering benefits to our members, primarily associated with our provider services and pharmacy operations, are included with benefits expense. The amount of this expense was ~~$29~~$31 million and ~~$39~~$30 million for the three months ended ~~March 31,~~June 30, 2019 and 2018, respectively. For the six months ended June 30, 2019 and 2018, the amount of this expense was $60 million and $69 million, respectively.

Other than those described previously, the accounting policies of each segment are the same and are described in Note 2 to the consolidated financial statements included in our 2018 Form 10-K. Transactions between reportable segments primarily consist of sales of services rendered by our Healthcare Services segment, primarily pharmacy, provider, and clinical care services, to our Retail and Group and Specialty segment customers. Intersegment sales and expenses are recorded at fair value and eliminated in consolidation. Members served by our segments often use the same provider networks, enabling us in some instances to obtain more favorable contract terms with providers. Our segments also share indirect costs and assets. As a result, the profitability of each segment is interdependent. We allocate most operating expenses to our segments. Assets and certain corporate income and expenses are not allocated to the segments, including the portion of investment income not supporting segment operations, interest expense on corporate debt, and certain other corporate expenses. These items are managed at a corporate level. These corporate amounts are reported separately from our reportable segments and are included with intersegment eliminations in the tables presenting segment results below.

Executive Overview

General

Humana Inc., headquartered in Louisville, Kentucky, is a leading health and well-being company committed to

helping our millions of medical and specialty members achieve their best health. Our successful history in care delivery and health plan administration is helping us create a new kind of integrated care with the power to improve health and well being and lower costs. Our efforts are leading to a better quality of life for people with Medicare, families, individuals, military service personnel, and communities at large. To accomplish that, we support physicians and other health care professionals as they work to deliver the right care in the right place for their patients, our members. Our range of clinical capabilities, resources and tools, such as in home care, behavioral health, pharmacy services, data analytics and wellness solutions, combine to produce a simplified experience that makes health care easier to navigate and more effective.

Our industry relies on two key statistics to measure performance. The benefit ratio, which is computed by taking

total benefits expense as a percentage of premiums revenue, represents a statistic used to measure underwriting profitability. The operating cost ratio, which is computed by taking total operating costs, excluding depreciation and amortization, as a percentage of total revenue less investment income, represents a statistic used to measure administrative spending efficiency.

Acquisitions and Divestitures

In the third quarter of 2018, we completed the sale of our wholly-owned subsidiary KMG to CGIC. KMG's subsidiary, KIC, included our closed block of non-strategic commercial long-term care policies. Upon closing, we funded the transaction with approximately $190 million of parent company cash contributed into KMG, subject to customary adjustments, in addition to the transfer of approximately $160 million of statutory capital with the sale.

Also in the third quarter of 2018, we, along with TPG and WCAS, completed the acquisitions of Kindred and Curo, respectively, merging Curo with the hospice business of Kindred at Home. As part of these transactions, we acquired a 40% minority interest in Kindred at Home, a leading home health and hospice company, for total cash consideration of approximately $1.1 billion.

In the second quarter of 2018, we acquired FPG for cash consideration of approximately $185 million, net of cash received. FPG is one of the largest at-risk providers serving Medicare Advantage and Managed Medicaid HMO patients in Greater Orlando, Florida with a footprint that includes clinics located in Lake, Orange, Osceola and Seminole counties. The acquisition of FPG advances our strategy of helping physicians and clinicians evolve from treating health episodically to managing health holistically.

In the first quarter of 2018, we acquired the remaining equity interest in MCCI, a privately held management service organization headquartered in Miami, Florida, that primarily coordinates medical care for Medicare Advantage beneficiaries in Florida and Texas. The purchase price consisted primarily of $169 million cash, as well as our existing investment in MCCI and a note receivable and a revolving note with an aggregate balance of $383 million.

These transactions are more fully discussed in Note 1 and Note 3 to the condensed consolidated financial statements.

Business Segments

The Retail segment consists of Medicare benefits, marketed to individuals or directly via group Medicare accounts. In addition, the Retail segment also includes our contract with CMS to administer the Limited Income Newly Eligible Transition, or LI-NET, prescription drug plan program and contracts with various states to provide Medicaid, dual eligible, and Long-Term Support Services benefits, which we refer to collectively as our state-based contracts. The Group and Specialty segment consists of employer group commercial fully-insured medical and specialty health insurance benefits marketed to individuals and employer groups, including dental, vision, and other supplemental health benefits, as well as administrative services only, or ASO products. In addition, our Group and Specialty segment includes military services business, primarily our TRICARE T2017 East Region contract. The Healthcare Services segment includes our services offered to our health plan members as well as to third parties, including pharmacy solutions, provider services, and clinical care service, such as home health and other services and capabilities to promote wellness and advance population health, including our minority investment in Kindred at Home. We reported under the category of Other Businesses those businesses that did not align with the reportable segments described above, primarily our closed-block long-term care insurance policies, which were sold in 2018.

The results of each segment are measured by segment earnings, and for our Healthcare Services Segment, also include the equity in net earnings of Kindred at Home. Transactions between reportable segments primarily consist of sales of services rendered by our Healthcare Services segment, primarily pharmacy, provider, and clinical care services, to our Retail and Group and Specialty segment customers. Intersegment sales and expenses are recorded at fair value and eliminated in consolidation. Members served by our segments often use the same provider networks, enabling us in some instances to obtain more favorable contract terms with providers. Our segments also share indirect costs and assets. As a result, the profitability of each segment is interdependent. We allocate most operating expenses to our segments. Assets and certain corporate income and expenses are not allocated to the segments, including the portion of investment income not supporting segment operations, interest expense on corporate debt, and certain other corporate expenses. These items are managed at a corporate level. These corporate amounts are reported separately from our reportable segments and are included with intersegment eliminations.

Seasonality

One of the product offerings of our Retail segment is Medicare stand-alone prescription drug plans, or PDPs, under the Medicare Part D program. Our quarterly Retail segment earnings and operating cash flows are impacted by the Medicare Part D benefit design and changes in the composition of our membership. The Medicare Part D benefit design results in coverage that varies as a member’s cumulative out-of-pocket costs pass through successive stages of a member’s plan period, which begins annually on January 1 for renewals. These plan designs generally result in us sharing a greater portion of the responsibility for total prescription drug costs in the early stages and less in the latter stages. As a result, the PDP benefit ratio generally decreases as the year progresses. In addition, the number of ~~low-income~~low-

income senior members as well as year-over-year changes in the mix of membership in our stand-alone PDP products affects the quarterly benefit ratio pattern.

In addition, the Retail segment also experiences seasonality in the operating cost ratio as a result of costs incurred in the second half of the year associated with the Medicare marketing season.

Our Group and Specialty segment also experiences seasonality in the benefit ratio pattern. However, the effect is opposite of Medicare stand-alone PDP in the Retail segment, with the Group and Specialty segment’s benefit ratio increasing as fully-insured members progress through their annual deductible and maximum out-of-pocket expenses.

2019 Highlights

Our strategy offers our members affordable health care combined with a positive consumer experience in growing markets. At the core of this strategy is our integrated care delivery model, which unites quality care, high member engagement, and sophisticated data analytics. Our approach to primary, physician-directed care for our members aims to provide quality care that is consistent, integrated, cost-effective, and member-focused, provided by both employed physicians and physicians with network contract arrangements. The model is designed to improve health outcomes and affordability for individuals and for the health system as a whole, while offering our members a simple, seamless healthcare experience. We believe this strategy is positioning us for long-term growth in both membership and earnings. We offer providers a continuum of opportunities to increase the integration of care and offer assistance to providers in transitioning from a fee-for-service to a value-based arrangement. These include performance bonuses, shared savings and shared risk relationships. At ~~March 31,~~June 30, 2019, approximately ~~2,223,300~~2,272,300 members, or 65%, of our individual Medicare Advantage members were in value-based relationships under our integrated care delivery model, as compared to ~~1,959,400~~1,978,200 members, or 65%, at ~~March 31,~~June 30, 2018. Medicare Advantage and dual demonstration program membership enrolled in a Humana chronic care management program was ~~834,700~~853,600 at ~~March 31,~~June 30, 2019, an increase of ~~10.9%~~13.4% from ~~752,400~~752,700 at ~~March 31,~~June 30, 2018. These members may not be unique to each program since members have the ability to enroll in multiple programs. The increase is driven by our improved process for identifying and enrolling members in the appropriate program at the right time, coupled with growth in Special Needs Plans, or SNP, membership and the insuring of certain SNP membership to Humana At Home's care management program.

Net income increased ~~15.3%~~$747 million from $193 million in 2018 to $940 million in 2019 and earnings per diluted common share increased ~~17.8%~~$5.55 from $1.39 earnings per diluted common share in 2018 to $6.94 earnings per diluted common share in 2019. This comparison was primarily impacted by the ~~2019 quarter. This growth was mainly due to~~loss on the ~~year-over-year improvement in our Retail segment results,~~sale of KMG recognized during the three months ended June 30, 2018 as well as the beneficial impact of the ~~temporary~~ suspension of the health industry insurance fee in 2019. The year-over-year comparisons were further impacted by the improvement in our Retail and Healthcare Services segment results, partially offset by the lower Group and Specialty segment results as detailed in the discussion that follows, as well as the impact of previously implemented productivity initiatives which have led to significant operating cost efficiencies in our segments. In addition, year-over-year comparisons are favorably impacted by a lower number of shares used to compute dilutive earnings per share, primarily reflecting share repurchases.

Contributing to our Retail segment revenue growth was our individual Medicare Advantage membership, which increased ~~414,800~~457,300 members, or ~~13.7%~~15.1%, from ~~March 31,~~June 30, 2018 to ~~March 31,~~June 30, 2019.

~~Excluding the impact from the early receipt of the Medicare premium remittance of $3.3 billion in the 2018 quarter, our~~Our operating cash flow of ~~$896 million~~$2.3 billion for ~~the~~ 2019 ~~quarter~~ improved primarily from the timing of ~~working capital items and~~the mid-year Medicare risk adjustment premium revenue collections which were received during the second quarter of 2019 as compared to the third quarter of 2018, higher earnings, ~~including the effect of Medicare Advantage membership growth.~~

On April 1, 2019, CMS published its 2020 Medicare Advantage Capitation Rates and Medicare Advantage and Part D Payment Policies and Final Call Letter (the Final Rate Notice). We expect the Final Rate Notice to result in a 2.2 percent rate increase for our individual Medicare Advantage business versus CMS’ estimate for the sector of 2.53 percent, excluding the impact of ~~Employer Group Waiver Plan (EGWP) funding changes,~~approximately $230 million payment related to reinsuring certain voluntary benefit and financial protection products to a third party in connection with the sale of KMG in 2018, as well as the timing of other working capital changes.

On July 31, 2019, we announced that we intend to enter into an agreement with a third party financial institution to effect a $1 billion accelerated stock repurchase program. We will repurchase shares through the program as part of the $3 billion authorized on July 30, 2019. The actual number of shares repurchased under the

agreement will be determined based on a ~~comparable basis.The difference between~~volume-weighted average price of our common stock during the ~~Humana projection and the CMS projection results from small differences in various components of the rate.~~purchase period.

Health Care Reform

The Health Care Reform Law enacted significant reforms to various aspects of the U.S. health insurance industry. Certain significant provisions of the Health Care Reform Law include, among others, mandated coverage requirements, mandated benefits and guarantee issuance associated with commercial medical insurance, rebates to policyholders based on minimum benefit ratios, adjustments to Medicare Advantage premiums, the establishment of federally facilitated or state-based exchanges coupled with programs designed to spread risk among insurers, and the introduction of plan designs based on set actuarial values. In addition, the Health Care Reform Law established insurance industry

assessments, including an annual health insurance industry fee. The annual health insurance industry fee levied on the insurance industry was $14.3 billion in 2018 and was not deductible for income tax purposes, which significantly increased our effective income tax rate. A one year suspension of the health insurance industry fee, as we experienced in 2017 and are experiencing in 2019, significantly impacts our trend in key operating metrics including our operating cost and medical expense ratios, as well as our effective tax rate. The annual health insurance industry fee is scheduled to resume for calendar year 2020 under current law.

It is reasonably possible that the Health Care Reform Law and related regulations, as well as future legislative, judicial or regulatory changes, including restrictions on our ability to manage our provider network or otherwise operate our business, or restrictions on profitability, including reviews by regulatory bodies that may compare our Medicare Advantage profitability to our non-Medicare Advantage business profitability, or compare the profitability of various products within our Medicare Advantage business, and require that they remain within certain ranges of each other, increases in member benefits or member eligibility criteria without corresponding increases in premium payments to us, or increases in regulation of our prescription drug benefit businesses, in the aggregate may have a material adverse effect on our results of operations (including restricting revenue, enrollment and premium growth in certain products and market segments, restricting our ability to expand into new markets, increasing our medical and operating costs, further lowering our Medicare payment rates and increasing our expenses associated with the non-deductible health insurance industry fee and other assessments); our financial position (including our ability to maintain the value of our goodwill); and our cash flows.

In addition, a number of proposals are being considered at the federal and state levels that would increase regulation of our prescription drug benefit and related businesses. For example, one proposal currently under consideration includes proposed federal regulation of drug rebates that would materially alter the treatment of rebates that are allowed in public programs and require rebates to be reflected at the point-of-sale. These reforms have the potential to have broad impacts on our prescription drug benefit and related businesses.

We intend for the discussion of our financial condition and results of operations that follows to assist in the understanding of our financial statements and related changes in certain key items in those financial statements from year to year, including the primary factors that accounted for those changes. Transactions between reportable segments primarily consist of sales of services rendered by our Healthcare Services segment, primarily pharmacy, provider, and clinical care services, to our Retail and Group and Specialty segment customers and are described in Note 15 to the condensed consolidated financial statements included in this report.

Comparison of Results of Operations for 2019 and 2018

Summary

Net income was ~~$566~~$940 million, or ~~$4.16~~$6.94 per diluted common share, in the 2019 quarter compared to ~~$491~~$193 million, or ~~$3.53~~$1.39 per diluted common share, in the 2018 quarter. ~~This increase~~Net income was ~~mainly due to the year-over-year improvement in our Retail segment results as discussed~~$1.5 billion, or $11.10 per diluted common share, in the ~~detailed discussion that follows,~~2019 period compared to $684 million, or $4.93 per diluted common share, in the 2018 period. These increases were primarily impacted by the loss on the sale of KMG recognized during the three months ended June 30, 2018 as well as the beneficial impact of the ~~temporary~~ suspension of the health industry insurance fee in 2019. The year-over-year comparisons were further impacted by the improvement in our Retail and Healthcare Services segment results, partially offset by the lower Group and Specialty segment results as detailed in the discussion that follows, as well as the impact of previously implemented productivity initiatives which have led to significant operating cost efficiencies in our segments. In addition, year-over-year comparisons are favorably impacted by a lower number of shares used to compute dilutive earnings per share, primarily reflecting share repurchases.

Premiums Revenue

Consolidated premiums increased ~~$1.84~~$2.1 billion, or ~~13.3%~~15.0%, from the 2018 quarter to ~~$15.7~~$15.8 billion for the 2019 quarter and increased $3.9 billion, or 14.2%, from the 2018 period to $31.4 billion for the 2019 period primarily due to higher premiums in the Retail segment, ~~mainly resulting from~~driven by membership growth ~~in our Medicare Advantage business~~ and higher per member premiums in our Medicare Advantage business. These increases were partially offset by the impact of declining stand-alone PDP membership year-over-year, as well as lower premiums in the Group and Specialty segment as discussed in the detailed segment results discussion that follows.

Services Revenue

Consolidated services revenue ~~increased $28~~decreased $27 million, or ~~8.6%~~7.1%, from the 2018 quarter to $355 million for the 2019 quarter primarily due to ~~an increase~~a decline in services revenue in the Group and Specialty and Healthcare Services ~~segment~~segments as ~~discussed~~detailed in the ~~detailed~~ segment results discussion that follows. Consolidated services revenue was relatively unchanged at $710 million for the 2019 period increasing $1 million, or 0.1%, from the 2018 period.

Investment Income

Investment income totaled ~~$101~~$114 million for the 2019 quarter, decreasing ~~$40~~$50 million, or ~~28.4%~~30.5%, from ~~$141~~$164 million for the 2018 ~~quarter,~~quarter. For the 2019 period, investment income totaled $215 million, decreasing $90 million, or 29.5%, from $305 million in the 2018 period. These decreases primarily ~~reflecting~~reflect lower realized capital gains and lower average invested ~~balances.~~balances, partially offset by higher interest rates.

Benefits Expense

Consolidated benefits expense was ~~$13.5~~$13.3 billion for the 2019 quarter, an increase of $1.8 billion from the 2018 quarter. For the 2019 period, benefits expense was $26.8 billion, an increase of $3.6 billion from the 2018 period. The consolidated benefit ratio for the 2019 quarter of 84.4% increased 30 basis points from 84.1% in the 2018 quarter. The consolidated benefit ratio for the 2019 period increased 100 basis points to 85.3% from 84.3% in the 2018 period. These increases were primarily due to the ~~temporary~~ suspension of the health insurance industry fee in 2019, which was contemplated in the pricing and benefit design of our products, lower favorable prior-period claims medical reserve development, including the impact of the exit of the Individual Commercial business, and an increase in the ~~growth~~Group and Specialty benefit ratio as discussed in ~~individual Medicare Advantage membership. At~~ the ~~onset, on average, new~~detailed segment results discussion that follows. These increases were partially offset by engaging our Medicare Advantage members ~~typically have a higher benefit ratio than existing Medicare Advantage members as they were not previously engaged~~ in clinical programs, oras well as ensuring they are appropriately documented under the CMS risk-adjustment ~~model.~~model, and lower than expected medical costs as compared to the assumptions used in the pricing of our individual Medicare Advantage business for 2019.

The favorable prior-period medical claims reserve development decreased the consolidated benefit ratio by approximately ~~170~~10 basis points in the 2019 quarter versus approximately ~~190~~50 basis points in the 2018 quarter. The favorable prior-period medical claims reserve development decreased the consolidated benefit ratio by approximately 90 basis points to 84.4% for the 2019 period compared to approximately 120 basis points to 84.1% for the 2018 period.

Operating Costs

Our segments incur both direct and shared indirect operating costs. We allocate the indirect costs shared by the segments primarily as a function of revenues. As a result, the profitability of each segment is interdependent.

Consolidated operating costs decreased ~~$89~~$58 million, or ~~5.1%~~3.3%, during the 2019 quarter compared to the 2018 quarter and decreased $147 million, or 4.2%, during the 2019 period compared to the 2018 period. These decreases were primarily due to a decrease in operating costs in the Retail and the Group and Specialty segments.

The consolidated operating cost ratio for the 2019 quarter of ~~10.4%~~10.6% decreased ~~200~~190 basis points from 12.5% in the 2018 quarter and for the 2019 period decreased 190 basis points to 10.5% from 12.4% in the 2018 period. These decreases were primarily due to the ~~temporary~~ suspension of the health insurance industry fee in 2019 and operating cost efficiencies in ~~the~~ 2019 ~~quarter, primarily the Retail segment,~~ driven by previously implemented productivity initiatives. These improvements were partially offset by strategic investments in our integrated care delivery ~~model.~~model and the impact of higher compensation expense accruals for the annual incentive program, or AIP, offered to employees across all levels. The higher accruals resulted from the continued strong performance, including improved customer satisfaction as measured by our net promoter score, along with higher than anticipated individual Medicare Advantage membership. The non-deductible health insurance industry fee impacted the operating cost ratio by ~~190~~180 basis points in both the 2018 ~~quarter.~~

quarter and period.

Depreciation and Amortization

Depreciation and amortization for the 2019 quarter totaled ~~$107~~$109 million compared to $100 million for the 2018 quarter. For the 2019 period, depreciation and amortization totaled $216 million compared to $200 million for the 2018 period.

Interest Expense

Interest expense for the 2019 quarter of ~~$62~~$60 million increased $9$7 million, compared to $53 million for the 2018 ~~quarter,~~quarter. Interest expense for the 2019 period of $122 million increased $16 million, compared to $106 million for the 2018 period. These increases were primarily due to the higher average borrowings outstanding including the impact of the borrowings under the November 2018 term loan agreement.

Income Taxes

~~For the 2019 quarter our~~The effective income tax rate was ~~24.4%~~24.3% for the six months ended June 30, 2019 compared to ~~the effective tax rate of 30.7%~~5.8% for the six months ended June 30, 2018, ~~period,~~ primarily due to the impact of the ~~temporary~~ suspension of the non-deductible health insurance industry fee in 2019 as well as the deferred tax benefit recognized in 2018 from the loss on sale of KMG. The effective income tax rate was 24.2% for the three months ended June 30, 2019. The effective income tax rate for the three months ended June 30, 2018 reflects a $430 million deferred tax benefit recorded during the three months ended June 30, 2018, resulting from the loss on the sale of KMG attributable to its original tax basis and subsequent capital contributions to fund accumulated losses.

Segment Earnings

Retail segment earnings increased ~~$198~~$363 million, or ~~74.2%~~73.6%, from ~~$267~~$493 million in the 2018 quarter to ~~$465~~$856 million in the 2019 quarter primarily due the segment's lower benefit and operating cost ratios, as well as increased premiums, primarily associated with significant growth in our individual Medicare Advantage membership as more fully described below. Retail segment earnings increased $561 million, or 73.8%, from $760 million in the 2018 period to $1.3 billion in the 2019 period primarily reflecting the lower operating cost ratio along with increased premiums associated with the significant growth in our individual Medicare Advantage membership, partially offset by the segment's higher benefit ratio as more fully described below.

Enrollment

Individual Medicare Advantage membership increased ~~414,800~~457,300 members, or ~~13.7%~~15.1%, from ~~March 31,~~June 30, 2018 to ~~March 31,~~June 30, 2019, primarily due to membership additions associated with the most recent Annual Election Period, or AEP, and Open Election Period (OEP) for Medicare beneficiaries. The OEP sales period, which ran from January 1 to March 31, added approximately ~~28,700~~43,700 members ~~through March 31, 2019.~~. The increase in Individual Medicare Advantage membership includes the addition of approximately ~~42,000~~55,200 Dual Eligible Special Need Plan (D-SNP) members from ~~March 31,~~June 30, 2018 to ~~March 31,~~June 30, 2019.

Group Medicare Advantage membership increased ~~25,200,~~26,000, or ~~5.1%~~5.3%, from ~~March 31,~~June 30, 2018 to ~~March 31,~~June 30, 2019, primarily due to net membership additions associated with the most recent AEP for Medicare beneficiaries.

Medicare stand-alone PDP membership decreased ~~593,700~~607,700 members, or ~~11.8%~~12.1%, from ~~March 31,~~June 30, 2018 to ~~March 31,~~June 30, 2019 reflecting net declines during the most recent AEP for Medicare beneficiaries. These anticipated declines were primarily due to the competitive nature of the industry and the pricing discipline we have employed, which has resulted in us no longer being the low cost plan in any market for 2019.

State-based Medicaid membership increased ~~125,300~~140,000 members, or ~~37.3%~~43.1%, from ~~March 31,~~June 30, 2018 to ~~March 31,~~June 30, 2019, primarily driven by the statewide award of a comprehensive contract under the Managed Medical Assistance (MMA) program in Florida.

Premiums Revenue

Retail segment premiums increased ~~$1.9~~$2.1 billion, or ~~15.7%~~17.5%, from the 2018 quarter to the 2019 quarter and increased $4.0 billion, or 16.6%, from the 2018 period to the 2019 period primarily due to individual and group Medicare Advantage membership growth and higher per member premiums, ~~in the most recent AEP,~~ as well as increased state-based contracts membership. These favorable items were partially offset by the decline in membership in our stand-alone PDP offerings.

Benefits Expense

The Retail segment benefit ratio ~~increased 90~~decreased 30 basis points from ~~87.4%~~85.5% in the 2018 quarter to ~~88.3%~~85.2% in the 2019 quarter primarily ~~due~~as a result of engaging our Medicare Advantage members in clinical programs, as well as ensuring that they are appropriately documented under the CMS risk-adjustment model. In addition the decreases were impacted by the lower than expected medical costs as compared to the ~~temporary~~pricing assumptions used in our individual Medicare Advantage business for 2019. This improvement was partially offset by the suspension of the health insurance industry fee in 2019 which was contemplated in the pricing and benefit design of our products, and ~~higher individual Medicare Advantage membership growth. At~~lower favorable prior-period medical reserve development in the ~~onset, our new Medicare Advantage members typically have a higher~~2019 quarter. The Retail segment benefit ratio ~~than existing Medicare Advantage members as they~~increased 20 basis points from 86.5% in the 2018 period to 86.7% in the 2019 period, primarily reflecting the net-negative impact of the same factors that affected the 2019 quarter described above. These increases were ~~not previously engaged in clinical programs or appropriately documented under the CMS risk-adjustment model. These items are~~ partially offset by ~~the impact of engaging our new 2018 Medicare Advantage members in clinical programs and ensuring that they are appropriately documented under the CMS risk-adjustment model,~~ higher favorable ~~prior period~~prior-period reserve development and the impact of a less severe flu season in the 2019 ~~quarter.~~period.

The Retail ~~segment’s~~segment's benefits expense for the 2019 quarter included ~~$283~~$28 million in favorable prior-period medical claims reserve development versus ~~$187~~$60 million in the 2018 quarter. For the 2019 period, the Retail segment’s benefit expense includes the beneficial effect of $311 million in favorable prior-period reserve development versus $247 million in the 2018 period. Prior-period medical claims reserve development decreased the Retail segment benefit ratio by approximately ~~200~~20 basis points in the 2019 quarter versus approximately ~~150~~50 basis points in the 2018 quarter.

~~Operating Costs~~

~~The~~ Favorable prior-period reserve development decreased the Retail segment ~~operating cost~~benefit ratio ~~of 8.2% for~~by approximately 110 basis points in the 2019 quarter decreased 190 basis points from 10.1% for the 2018 quarter, primarily due to the temporary suspension of the health insurance industry fee in 2019, as well as operating costs efficiencies from previously implemented productivity initiatives. These decreases

~~were partially offset by the strategic investments in our integrated care delivery model. The non-deductible health insurance industry fee impacted the operating cost ratio by 190~~period versus approximately 100 basis points in the 2018 period.

Operating Costs

•

The Retail segment operating cost ratio of 8.5% for the 2019 quarter decreased 160 basis points from 10.1% for the 2018 quarter. The Retail segment operating cost ratio of 8.4% for the 2019 period decreased 170 basis points from 10.1% for the 2018 period. The year-over-year comparison was primarily due to the suspension of the health insurance industry fee in 2019, as well as operating costs efficiencies from previously implemented productivity initiatives. These decreases were partially offset by the strategic investments in our integrated care delivery model and the impact of higher compensation expense accruals in 2019 for the AIP as a result of our continued strong performance. The non-deductible health insurance industry fee impacted the operating cost ratio by 190 basis points in the 2018 quarter and period.

Segment Earnings

Group and Specialty segment earnings decreased $121 million, or 41.6%, from $291 million in the 2018 period to $170 million in the 2019 period. These decreases were primarily due to a higher benefit ratio, along with lower military services business earnings. Earnings comparisons related to the military services business were unfavorably impacted by the receipt of certain contractual incentives and adjustments in ~~the~~ 2018 ~~quarter~~ related to the previous TRICARE contract which did not recur in ~~the 2019 quarter. This was~~2019. These decreases were partially offset by ~~a lower~~improvement in the operating cost ratio ~~in the 2019 quarter and a favorable year -over-year earnings comparison for our group ASO commercial medical business.~~as more fully described below.

Enrollment

Fully-insured commercial group medical membership decreased ~~116,900~~108,400 members, or ~~10.9%~~10.3%, from ~~March 31,~~June 30, 2018 to ~~March 31,~~June 30, 2019 primarily reflecting lower membership in small group accounts due in part to more

small group accounts selecting level-funded ASO products in 2019, as well as the loss of certain large group accounts due to the competitive pricing environment. The portion of group fully-insured commercial medical membership in small group accounts was approximately ~~61 percent~~61% at ~~March 31,~~June 30, 2019 and ~~63 percent~~62% at ~~March 31,~~June 30, 2018.

Group ASO commercial medical membership increased ~~26,000~~37,200 members, or ~~5.7%~~8.1%, from ~~March 31,~~June 30, 2018 to ~~March 31,~~June 30, 2019 reflecting more small group accounts selecting level-funded ASO products in 2019, partially offset by the loss of certain large group accounts as a result of continued discipline in pricing of services for self-funded accounts amid a highly competitive environment.

Military services membership increased ~~11,400~~39,900 members, or ~~0.2%~~0.7%, from ~~March 31,~~June 30, 2018 to ~~March 31,~~June 30, 2019. Membership includes military service members, retirees, and their families to whom the company ~~is providing~~provides healthcare services under the current T2017 TRICARE East Region contract. The current contract, which covers 32 states, became effective on January 1, 2018.

Specialty membership decreased ~~903,700~~367,700 members, or ~~13.4%~~5.9%, from ~~March 31,~~June 30, 2018 to ~~March 31,~~June 30, 2019 primarily due to the exit of our voluntary benefits and financial protection products in connection with the ~~previously disclosed~~ sale of KMG ~~which resulted~~ in ~~the loss of approximately 600,000 members,~~2018, as well as the loss of some group accounts offering stand-alone dental and vision products.

Premiums Revenue

Group and Specialty segment premiums decreased ~~$55~~$17 million, or ~~3.2%~~1.0%, from the 2018 quarter to ~~$1.68~~$1.67 billion for the 2019 quarter and decreased $72 million, or 2.1%, from the 2018 period to $3.36 billion for the 2019 period. These decreases were primarily due to a decline in our fully-insured group commercial and specialty membership ~~as well as due to reinsuring~~and the exit of our voluntary ~~benefits~~benefit and financial protection products ~~to a third party~~ in connection with the ~~previously disclosed~~ sale of KMG ~~during the second quarter of~~in 2018. These decreases were partially offset by higher stop-loss revenues related to our level-funded ASO accounts resulting from membership growth in this product. Additionally, the impact of the lower unfavorable commercial risk adjustment, or CRA, payable estimates in ~~the~~ 2019 ~~quarter~~ as compared to ~~the~~ 2018 ~~quarter~~ resulted in higher small group fully-insured commercial revenues.

Services Revenue

Group and Specialty segment services revenue decreased ~~$25~~$15 million, or ~~11.4%~~7.2%, from the 2018 quarter to ~~$194~~$193 million for the 2019 quarter and decreased $40 million, or 9.4%, from the 2018 period to $387 million for the 2019 period primarily due to the impact of certain contractual incentives and adjustments related to the previous TRICARE contract received in ~~the~~ 2018, ~~quarter,~~ which did not recur in ~~the 2019 quarter,~~2019.

Benefits Expense

The Group and Specialty segment benefit ratio increased ~~320~~590 basis points from ~~73.2%~~80.4% in the 2018 quarter to ~~76.4%~~86.3% in the 2019 ~~quarter~~quarter. The Group and Specialty segment benefit ratio increased 460 basis points from 76.7% in the 2018 period to 81.3% in the 2019 period. These increases were primarily due to the impact of unfavorable prior-period reserve development in ~~the~~ 2019, ~~quarter,~~ the ~~temporary~~ suspension of the health insurance industry fee in 2019 which was contemplated in the pricing of our products, as well as membership mix, including the continued migration of ~~healthier~~ groups to level-funded ASO products in ~~the 2019 quarter.~~2019. These ~~increases~~items were partially offset by ~~lower ASO stop-loss claims.~~the smaller unfavorable premium adjustment in 2019 as compared to 2018 related to our CRA accrual associated with the ACA-compliant business as a result of the release of CMS's final 2018 CRA data.

The Group and Specialty segment's benefits expense included ~~$16~~$20 million in ~~the 2019 quarter of~~ unfavorable prior-period medical claims reserve development in the 2019 quarter versus ~~$34 million~~none in the 2018 ~~quarter of favorable prior-period medical claims reserve development.

This unfavorable prior-period medical claims reserve development increased the Group and Specialty segment benefit ratio by approximately ~~100~~120 basis points in the 2019 quarter and had no impact in the 2018 quarter. The Group and Specialty segment's benefits expense included the effect of an unfavorable prior-period medical claims reserve development of $36 million in the 2019 period versus favorable prior-period medical claims reserve development ~~decreased~~of $34 million in the 2018 period.

Operating Costs

The Group and Specialty segment operating cost ratio of ~~21.9%~~21.7% for the 2019 quarter decreased ~~170~~180 basis points from 23.5% for the 2018 quarter. For the 2019 period, the Group and Specialty segment operating cost ratio of 21.8% decreased 180 basis points from 23.6% for the 2018 ~~quarter~~period. These improvements primarily were due to the ~~temporary~~ suspension of the health insurance industry fee in 2019, as well as operating cost efficiencies in the 2019 quarter driven by previously implemented productivity initiatives. The ~~decrease~~improvement was further impacted by the exit of the voluntary benefits and financial protection products in connection with the previously disclosed sale of KMG recognized during the second quarter of 2018, which carried a higher operating cost ratio. These improvements were offset by the higher compensation expense accruals in 2019 for the AIP as a result of our continued strong performance.

Healthcare Services segment earnings of ~~$175~~$224 million for the 2019 quarter increased $2$18 million, or ~~1.2%~~8.7%, from ~~$173~~$206 million in the 2018 quarter. For the 2019 period, the Healthcare Services segment earnings of $399 million increased $20 million, or 5.3%, from $379 million in the 2018 period. These increases were primarily due to the impact of Kindred at Home operations, higher earnings from our pharmacy operations, and the

improvement in core operating results from the provider services business. These factors were partially offset by additional investments in new clinical assets associated with our provider services business.

Script Volume

Humana Pharmacy Solutions script volumes on an adjusted 30-day equivalent basis increased to approximately ~~110~~113 million in the 2019 quarter, up ~~1.9%~~2.6%, versus scripts of approximately ~~108~~110 million in the 2018 ~~quarter,~~quarter.

our provider services business reflecting the acquisition of MCCI and FPG. These increases were partially offset by the loss of intersegment revenues associated with the reduction of stand-alone PDP membership.

Operating Costs

The Healthcare Services segment operating cost ratio of ~~96.6%~~96.1% and 96.3% for the 2019 quarter ~~increased 40 basis points~~and period, respectively, were relatively unchanged from 96.2% in both the 2018 quarter ~~primarily due to investments in our provider services business~~ and ~~a change in the mix of pharmacy spend as specialty drug spending continues to rise as a percentage of total spend.~~period.

Liquidity

Historically, our primary sources of cash have included receipts of premiums, services revenue, and investment and other income, as well as proceeds from the sale or maturity of our investment securities, borrowings, and proceeds from sales of businesses. Our primary uses of cash historically have included disbursements for claims payments, operating costs, interest on borrowings, taxes, purchases of investment securities, acquisitions, capital expenditures, repayments on borrowings, dividends, and share repurchases. Because premiums generally are collected in advance of claim payments by a period of up to several months, our business normally should produce positive cash flows during periods of increasing premiums and enrollment. Conversely, cash flows would be negatively impacted during periods of decreasing premiums and enrollment. From period to period, our cash flows may also be affected by the timing of working capital items including premiums receivable, benefits payable, and other receivables and payables. Our cash flows are impacted by the timing of payments to and receipts from CMS associated with Medicare Part D subsidies for which we do not assume risk. The use of cash flows may be limited by regulatory requirements of state departments of insurance (or comparable state regulators) which require, among other items, that our regulated subsidiaries maintain minimum levels of capital and seek approval before paying dividends from the subsidiaries to the parent. Our use of cash flows derived from our non-insurance subsidiaries, such as in our Healthcare Services segment, is generally not restricted by state departments of insurance (or comparable state regulators).

For additional information on our liquidity risk, please refer to the section entitled “Risk Factors” in our 2018 Form 10-K.

Cash and cash equivalents increased to approximately ~~$3.9~~$4.8 billion at ~~March 31,~~June 30, 2019 from $2.3 billion at December 31, 2018. The change in cash and cash equivalents for the ~~three~~six months ended ~~March 31,~~June 30, 2019 and 2018 is summarized as follows:

Cash Flow from Operating Activities

Our operating cash flows for the 2018 ~~quarter~~period were significantly impacted by the early receipt of the Medicare premium remittances of $3.3 billion in ~~March~~June 2018 because the payment date of ~~April~~July 1, 2018 fell on a weekend. Generally, when the first day of a month falls on a weekend or holiday, with the exception of January 1 (New Year's Day), we receive this payment at the end of the previous month. Excluding the 2018 ~~quarter~~ impact from the early receipt of the Medicare premium remittance, our operating cash flow for the 2019 ~~quarter~~period improved from the 2018 ~~quarter~~period primarily from the timing of the mid-year Medicare risk adjustment premium revenue collections which were received during the second quarter of 2019 as compared to the third quarter of 2018, higher earnings, the impact of approximately $230 million payment related to reinsuring certain voluntary benefit and financial protection products to a third party in connection with the sale of KMG in 2018, as well as the timing of other working capital ~~items and higher earnings, including the effect of Medicare Advantage membership growth.~~

changes.

The most significant drivers of changes in our working capital are typically the timing of payments of benefits expense and receipts for premiums. We illustrate these changes with the following summaries of benefits payable and receivables.

The detail of benefits payable was as follows at ~~March 31,~~June 30, 2019 and December 31, 2018:


	March 31, 2019		December 31, 2018		2019 Quarter Change		2018 Quarter Change			June 30, 2019		December 31, 2018		2019 Period Change		2018 Period Change

(1)

IBNR represents an estimate of benefits payable for claims incurred but not reported (IBNR) at the balance sheet date and includes unprocessed claim inventories. The level of IBNR is primarily impacted by membership levels, medical claim trends and the receipt cycle time, which represents the length of time between when a claim is initially incurred and when the claim form is received and processed (i.e. a shorter time span results in a lower IBNR). IBNR includes unprocessed claims inventories.


(2)	Reported claims in process represents the estimated valuation of processed claims that are in the post claim adjudication process, which consists of administrative functions such as audit and check batching and handling, as well as amounts owed to our pharmacy benefit administrator which fluctuate due to bi-weekly payments and the month-end cutoff.


(3)	Other benefits payable primarily include amounts owed to providers under capitated and risk sharing arrangements.

The increase in benefits payable from December 31, 2018 to ~~March 31,~~June 30, 2019 and from December 31, 2017 to ~~March 31,~~June 30, 2018 primarily was due to an increase in IBNR primarily as a result of Medicare Advantage membership growth, as

well as an increase in the amount of processed but unpaid claims which fluctuate due to month-end cutoff. The increase in benefits payable from December 31, 2018 to ~~March 31,~~June 30, 2019 was also impacted by an increase in the amounts owed to providers under the capitated and risk sharing arrangements.

The detail of total net receivables was as follows at ~~March 31,~~June 30, 2019 and December 31, 2018:


	March 31, 2019			December 31, 2018			2019 Quarter Change		2018 Quarter Change			June 30, 2019			December 31, 2018			2019 Period Change			2018 Period Change

quarter of 2018.

Cash Flow from Investing Activities

Net proceeds from investment securities sales and maturities in the 2019 ~~quarter~~period and 2018 period were ~~$284 million. In~~$385 million and $339 million, respectively.

During the 2018 ~~quarter, we reinvested a portion of our operating cash flows in investment securities, primarily investment-grade fixed income securities, totaling $102 million.~~

~~On March 1, 2018,~~period, we acquired the remaining equity interest in ~~MCCI. The purchase price included, in part,~~MCCI and acquired FPG for cash consideration of $169 million and $185 million, respectively, as discussed in Note 3 to the condensed consolidated financial statements.

Our ongoing capital expenditures primarily relate to our information technology initiatives, support of services in our provider services operations including medical and administrative facility improvements necessary for activities such as the provision of care to members, claims processing, billing and collections, wellness solutions, care coordination, regulatory compliance and customer service. Total capital expenditures, excluding acquisitions, were ~~$139~~$296 million in the 2019 ~~quarter~~period and ~~$134~~$272 million in the 2018 ~~quarter.~~period.

Cash Flow from Financing Activities

Receipts from CMS associated with Medicare Part D claim subsidies for which we do not assume risk were higher than claims payments by ~~$620~~$539 million ~~during~~in the 2019 ~~quarter~~period and ~~higher than claims payments by $1.4~~$1.6 billion ~~during~~in the 2018 ~~quarter.~~period.

Under our administrative services only TRICARE contracts, health care cost payments for which we do not assume risk exceeded reimbursements from the federal government by $66 million in the 2019 ~~quarter. In~~period and $33 million in the 2018 ~~quarter, health care cost~~period.

Claim payments ~~for which we do not assume risk exceeded reimbursements from the federal government by $28 million.~~

~~Receipts from~~to the Department of Health and Human Services, or HHS, associated with cost sharing provisions of the Health Care Reform Law for which we do not assume risk were ~~$16~~$13 million higher than reimbursements from HHS during the 2018 ~~quarter.~~period.

On March 26, 2018 we completed the final settlement of our accelerated stock repurchase along with 0.08 million additional share repurchases under the current stock repurchase authorization during the 2018 period for $24 million.

We also acquired common shares in connection with employee stock plans for an aggregate cost of $10 million in the 2019 ~~quarter~~period and ~~$51~~$69 million in the 2018 ~~quarter.~~period.

Net repayments of commercial paper were $356 million in the 2019 period and net proceeds from the issuance of commercial paper were ~~$17 million in the 2019 quarter and $245~~$243 million in the 2018 ~~quarter.~~period. The maximum principal amount outstanding at any one time during the 2019 quarter was ~~$801~~$670 million.

We paid dividends to stockholders of ~~$68~~$142 million during the 2019 ~~quarter~~period and ~~$57~~$126 million during the 2018 ~~quarter.~~period.

Acquisitions and Divestitures

During the 2018 ~~quarter,~~period, we completed the acquisition of MCCI and FPG for total cash consideration of ~~$169~~$354 million.

For a detailed discussion of ~~this transaction,~~these transactions, please refer to Note 3 to the condensed consolidated financial statements.

Liquidity Requirements

We believe our cash balances, investment securities, operating cash flows, and funds available under our credit agreement and our commercial paper program or from other public or private financing sources, taken together, provide adequate resources to fund ongoing operating and regulatory requirements, acquisitions, future expansion opportunities, and capital expenditures for at least the next twelve months, as well as to refinance or repay debt, and repurchase shares.

Adverse changes in our credit rating may increase the rate of interest we pay and may impact the amount of credit available to us in the future. Our investment-grade credit rating at ~~March 31,~~June 30, 2019 was BBB+ according to Standard & Poor’s Rating Services, or S&P, and Baa3 according to Moody’s Investors Services, Inc., or Moody’s. A downgrade by S&P to BB+ or by Moody’s to Ba1 triggers an interest rate increase of 25 basis points with respect to $250 million of our senior notes. Successive one notch downgrades increase the interest rate an additional 25 basis points, or annual interest expense by less than $1 million, up to a maximum 100 basis points, or annual interest expense by $3 million.

In addition, we operate as a holding company in a highly regulated industry. Humana Inc., our parent company, is dependent upon dividends and administrative expense reimbursements from our subsidiaries, most of which are subject to regulatory restrictions. We continue to maintain significant levels of aggregate excess statutory capital and surplus in our state-regulated operating subsidiaries. Cash, cash equivalents, and short-term investments at the parent company

were ~~$721 million~~$1.9 billion at ~~March 31,~~June 30, 2019 compared to $578 million at December 31, 2018. This increase primarily was due to insurance subsidiary dividends in excess of capital contributions from our parent company as well as operating cash derived from our non-insurance subsidiary earnings and other working capital ~~changes,~~changes. These increases were partially offset by the net repayment of commercial paper borrowings, capital expenditures, subsidiaries capital contributions, and cash dividends to shareholders. Our use of operating cash derived from our non-insurance subsidiaries, such as our Healthcare Services segment, is generally not restricted by departments of insurance (or comparable state regulator).

Regulatory Requirements

Certain of our subsidiaries operate in states that regulate the payment of dividends, loans, or other cash transfers to Humana Inc., our parent company, and require minimum levels of equity as well as limit investments to approved securities. The amount of dividends that may be paid to Humana Inc. by these subsidiaries, without prior approval by state regulatory authorities, or ordinary dividends, is limited based on the entity’s level of statutory income and statutory capital and surplus. If the dividend, together with other dividends paid within the preceding twelve months, exceeds a specified statutory limit or is paid from sources other than earned surplus, it is generally considered an extraordinary dividend requiring prior regulatory approval. In most states, prior notification is provided before paying a dividend even if approval is not required.

Although minimum required levels of equity are largely based on premium volume, product mix, and the quality of assets held, minimum requirements vary significantly at the state level. Based on the most recently filed statutory financial statements as of ~~December~~March 31, ~~2018,~~2019, our state regulated subsidiaries had aggregate statutory capital and surplus of approximately ~~$7.6~~$8.1 billion, which exceeded aggregate minimum regulatory requirements of ~~$5.2~~$5.5 billion. The amount of ~~ordinary~~ dividends ~~that may be~~ paid to our parent company inwas approximately $1.2 billion during the six months ended June 30, 2019 ~~is approximately $1~~compared to $1.9 billion induring the ~~aggregate. The amount, timing and mix of ordinary and extraordinary dividend payments will~~six months ended June 30, 2018. Actual dividends paid may vary year over year due to ~~state regulatory requirements, the level~~consideration of excess statutory capital and surplus and expected future surplus requirements related to, for example, premium volume and product mix. ~~Actual dividends that were paid to our parent company were approximately $2.3 billion in 2018.~~

Item 3. Quantitative and Qualitative Disclosures about Market Risk

Our earnings and financial position are exposed to financial market risk, including those resulting from changes in interest rates.

Interest rate risk also represents a market risk factor affecting our consolidated financial position due to our significant investment portfolio, consisting primarily of fixed maturity securities of investment-grade quality with a weighted average S&P credit rating of AA at ~~March 31,~~June 30, 2019. Our net unrealized position increased ~~$196~~$361 million from a net unrealized loss position of $204 million at December 31, 2018 to a net unrealized ~~loss~~gain position of $8$157 million at ~~March 31,~~June 30, 2019. At ~~March 31,~~June 30, 2019, we had gross unrealized losses of ~~$61~~$17 million on our investment portfolio primarily due to an increase in market interest rates since the time the securities were purchased. There were no material other-than-temporary impairments during the ~~three~~six months ended ~~March 31,~~June 30, 2019. While we believe that these impairments are temporary and we currently do not have the intent to sell such securities, given the current market conditions and the significant judgments involved, there is a continuing risk that future declines in fair value may occur and material realized losses from sales or other-than-temporary impairments may be recorded in future periods.

Duration is the time-weighted average of the present value of the bond portfolio’s cash flow. Duration is indicative of the relationship between changes in fair value and changes in interest rates, providing a general indication of the sensitivity of the fair values of our fixed maturity securities to changes in interest rates. However, actual fair values may differ significantly from estimates based on duration. The average duration of our investment portfolio, including cash and cash equivalents, was approximately ~~2.5~~2.1 years as of ~~March 31,~~June 30, 2019 and approximately 2.9 years as of December 31, 2018. The decline in the average duration is reflective of the longer duration securities associated with the sale of KMG. Based on the duration, including cash equivalents, a 1% increase in interest rates would generally decrease the fair value of our securities by approximately ~~$344~~$316 million at ~~March 31,~~June 30, 2019.

Item 4. Controls and Procedures

Under the supervision and with the participation of our Chief Executive Officer, or CEO, our Chief Financial Officer, or CFO, and our Principal Accounting Officer, we carried out an evaluation of the effectiveness of the design and operation of our disclosure controls and procedures for the quarter ended ~~March 31,~~June 30, 2019.

Based on our evaluation, our CEO, CFO, and our Principal Accounting Officer concluded that our disclosure controls and procedures are effective to provide reasonable assurance that information the Company is required to disclose in its reports under the Securities Exchange Act of 1934, as amended, is recorded, processed, summarized and reported within the time periods specified in SEC rules and forms, including, without limitation, ensuring that such information is accumulated and communicated to the Company’s management, including its principal executive and principal financial officers, or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure.

There have been no changes in the Company’s internal control over financial reporting during the quarter ended ~~March 31,~~June 30, 2019 that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.
