NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

1. BASIS OF PRESENTATION AND SIGNIFICANT EVENTS
The accompanying unaudited 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, 2022, that was filed with the Securities and Exchange Commission, or the SEC, on February 16, 2023. We refer to this Form 10-K as the “2022 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 unaudited 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 and indefinite-lived intangible assets. These estimates are based on knowledge of current events and anticipated future events, and accordingly, actual results may ultimately differ materially from those estimates. For additional information regarding accounting policies considered in preparing our consolidated financial statements, refer to Note 2 to the audited Consolidated Financial Statements included in Part II, Item 8, "Financial Statements and Supplementary Data" in our 2022 Form 10-K.
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.
Employer Group Commercial Medical Products Business Exit

In February 2023, we announced our planned exit from the Employer Group Commercial Medical Products business, which includes all fully insured, self-funded and Federal Employee Health Benefit medical plans, as well as associated wellness and rewards programs. No other Humana health plan offerings are materially affected. Following a strategic review, we determined the Employer Group Commercial Medical Products business was no longer positioned to sustainably meet the needs of commercial members over the long term or support our long-term strategic plans. The exit from this line of business will be phased over the 18 to 24 months following our February 2023 announcement.

Value Creation Initiatives
During 2022, in order to create capacity to fund growth and investment in our Medicare Advantage business and further expansion of our healthcare services capabilities in 2023, we committed to drive additional value for the enterprise through cost saving, productivity initiatives, and value acceleration from previous investments. As a result of these initiatives, during the second quarter of 2022, we recorded charges of $203 million. These charges primarily relate to $140 million in asset impairments, including software and abandonment, and $21 million of severance charges in connection with workforce optimization. The remainder of the charges primarily relate to external consulting fees. These charges were recorded at the corporate level and not allocated to the segments. There were no recurring charges in 2023.

COVID-19
The emergence and spread of the novel coronavirus, or COVID-19, beginning in the first quarter of 2020 has impacted our business. During periods of increased incidences of COVID-19, a reduction in non-COVID-19 hospital admissions for non-emergent and elective medical care have resulted in lower overall healthcare system utilization. At the same time, COVID-19 treatment and testing costs increased utilization. During 2022, we experienced lower overall utilization of the healthcare system than anticipated, as the reduction in COVID-19 utilization following the increased incidence associated with the Omicron variant outpaced the increase in non-COVID-19 utilization. The significant disruption in utilization during 2020 also impacted our ability to implement clinical initiatives to manage health care costs and chronic conditions of our members, and appropriately document their risk profiles, and, as such, significantly affected our 2021 revenue under the risk adjustment payment model for Medicare Advantage plans. Finally, changes in utilization patterns and actions taken in 2021 as a result of the COVID-19 pandemic, including the suspension of certain financial recovery programs for a period of time and shifting the timing of claim payments and provider capitation surplus payments, impacted our claim reserve development and operating cash flows for 2021.
The COVID-19 National Emergency declared in 2020 was terminated on April 10, 2023 and the Public Health Emergency expired on May 11, 2023.
Revenue Recognition
Our revenues include premiums and services revenue. Services revenue includes 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, services revenue includes net patient services revenue that are recorded based upon established billing rates, less allowances for contractual adjustments, and are recognized as services are provided. For additional information regarding our revenues, refer to Note 2 to the audited Consolidated Financial Statements included in Part II, Item 8, "Financial Statements and Supplementary Data" in our 2022 Form 10-K. For additional information regarding disaggregation of revenue by segment and type, refer to Note 14 to the unaudited Condensed Consolidated Financial Statements included in Part I, Item 1, "Financial Statements" of this Form 10-Q.
At June 30, 2023, accounts receivable related to services were $311 million. For the three and six months ended June 30, 2023, 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 June 30, 2023.
For the three and six months ended June 30, 2023, services revenue recognized from performance obligations related to prior periods, such as 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.

2. RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS
In November 2020, the FASB issued Accounting Standards Update No. 2020-11, Financial Services—Insurance (Topic 944): Effective Date and Early Application (“ASU 2020-11”). The amendments in ASU 2020-11 make changes to the effective date and early application of Accounting Standards Update No. 2018-12, Financial Services—Insurance (Topic 944): Targeted Improvements to the Accounting for Long-Duration Contracts (“ASU 2018-12”), which was issued in November 2018. The amendments in ASU 2020-11 have extended the original effective date by one year, and now the amendments are required for our interim and annual reporting periods beginning after December 15, 2022. The new guidance relates 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, including the amortization of deferred contract acquisition costs and the measurement of liabilities for future policy benefits using current, rather than locked-in, assumptions. The new guidance, limited to our Medicare Supplement product which represents less than 1% of consolidated premiums and services revenue, became effective for us beginning January 1, 2023 and is to be applied to contracts in force on the basis of their existing carrying value amounts at the beginning of the earliest period presented. The adoption of the new standard in 2023 did not have a material impact on our consolidated results of operations, financial position or 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
On August 11, 2022, we completed the sale of a 60% interest in Gentiva, formerly Kindred, Hospice to Clayton, Dubilier & Rice, or CD&R, for cash proceeds of approximately $2.7 billion, net of cash disposed, including debt repayments from Gentiva Hospice to Humana of $1.9 billion. In connection with the sale we recognized a pre-tax gain, net of transaction costs, of $237 million. For the three and six months ended June 30, 2022, the accompanying condensed consolidated statement of income includes revenues related to Gentiva Hospice of $399 million and $781 million, respectively, and pretax earnings of $64 million and $126 million, respectively.
During 2023 and 2022, we acquired various 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 acquired in 2023 and 2022 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 2023 and 2022 were not material to our results of operations. For asset acquisitions, the goodwill acquired is partially amortizable as deductible expenses for tax purposes. 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.

Approximately 98% of our debt securities were investment-grade quality, with a weighted average credit rating of AA by Standard & Poor's Rating Service, or S&P, at June 30, 2023. Most of the debt securities that were below investment-grade were rated BB-, the higher end of the below investment-grade rating scale. Tax-exempt municipal securities were diversified among general obligation bonds of states and local municipalities in the United States as well as special revenue bonds issued by municipalities to finance specific public works projects such as utilities, water and sewer, transportation, or education. Our general obligation bonds are diversified across the United States with no individual state exceeding 1% of our total debt securities. Our investment policy limits investments in a single issuer and requires diversification among various asset types.
Our unrealized losses from all debt securities were generated from approximately 1,740 positions out of a total of approximately 2,055 positions at June 30, 2023. All issuers of debt securities we own that were trading at an unrealized loss at June 30, 2023 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 these debt securities were purchased. At June 30, 2023, we did not intend to sell any debt securities with an unrealized loss position in accumulated other comprehensive income, and it is not likely that we will be required to sell these debt securities before recovery of their amortized cost basis. Additionally, we did not record any material credit allowances for debt securities that were in an unrealized loss position for the three and six months ended June 30, 2023 or 2022.
The detail of gains (losses) related to investment securities and included within investment income was as follows for the three and six months ended June 30, 2023 and 2022:
