Accounting Policies [Abstract]
Basis Of Presentation And Significant Accounting Policies	Basis of Presentation and Significant Accounting Policies Basis of Presentation: The accompanying consolidated financial statements include the accounts of Elevance Health and its subsidiaries and have been prepared in conformity with U.S. generally accepted accounting principles (“GAAP”). All significant intercompany accounts and transactions have been eliminated in consolidation. Certain of our subsidiaries operate outside of the United States and have functional currencies other than the U.S. dollar (“USD”). We translate the assets and liabilities of those subsidiaries to USD using the exchange rate in effect at the end of the period. We translate the revenues and expenses of those subsidiaries to USD using the average exchange rates in effect during the period. The net effect of these translation adjustments is included in “Foreign currency translation adjustments” in our consolidated statements of comprehensive income. Reclassifications: Certain prior year amounts have been reclassified to conform to the current year presentation. Use of Estimates: The preparation of consolidated financial statements in conformity with GAAP requires us to make estimates and assumptions that affect the amounts reported in our consolidated financial statements and accompanying notes. Our most significant estimate relates to estimates and judgments for medical claims payable. Actual results could differ from those estimates. Cash and Cash Equivalents: Cash and cash equivalents includes available cash and all highly liquid investments with maturities of three months or less when purchased. We control a number of bank accounts that are used exclusively to hold customer funds for the administration of customer benefits, and we have cash and cash equivalents on deposit to meet certain regulatory requirements. These amounts totaled $258 and $173 at December 31, 2022 and 2021, respectively, and are included in the cash and cash equivalents line on our consolidated balance sheets. Investments: We classify fixed maturity securities in our investment portfolio as “available-for-sale” and report those securities at fair value. Certain fixed maturity securities are available to support current operations and, accordingly, we classify such investments as current assets without regard to their contractual maturity. Investments used to satisfy contractual, regulatory or other requirements are classified as long-term, without regard to contractual maturity. If a fixed maturity security is in an unrealized loss position and we have the intent to sell the fixed maturity security, or it is more likely than not that we will have to sell the fixed maturity security before recovery of its amortized cost basis, we write down the fixed maturity security’s cost basis to fair value and record an impairment loss in our consolidated statements of income. For impaired fixed maturity securities that we do not intend to sell or if it is more likely than not that we will not have to sell such securities, but we expect that we will not fully recover the amortized cost basis, we recognize the credit component of the impairment as an allowance for credit loss in our consolidated balance sheets and record an impairment loss in our consolidated statements of income. The non-credit component of the impairment is recognized in accumulated other comprehensive loss. Furthermore, unrealized losses entirely caused by non-credit-related factors related to fixed maturity securities for which we expect to fully recover the amortized cost basis continue to be recognized in accumulated other comprehensive loss. The credit component of an impairment is determined primarily by comparing the net present value of projected future cash flows with the amortized cost basis of the fixed maturity security. The net present value is calculated by discounting our best estimate of projected future cash flows at the effective interest rate implicit in the fixed maturity security at the date of purchase. For mortgage-backed and asset-backed securities, cash flow estimates are based on assumptions regarding the underlying collateral, including prepayment speeds, vintage, type of underlying asset, geographic concentrations, default rates, recoveries and changes in value. For all other securities, cash flow estimates are driven by assumptions regarding probability of default, including changes in credit ratings and estimates regarding timing and amount of recoveries associated with a default. For asset-backed securities included in fixed maturity securities, we recognize income using an effective yield based on anticipated prepayments and the estimated economic life of the securities. When estimates of prepayments change, the effective yield is recalculated to reflect actual payments to date and anticipated future payments. The net investment in the securities is adjusted to the amount that would have existed had the new effective yield been applied since the purchase date of the securities. Such adjustments are reported within net investment income. The changes in fair value of our marketable equity securities are recognized in our results of operations within net gains and losses on financial instruments. Certain marketable equity securities are held to satisfy contractual obligations, and are reported under the caption “Other invested assets” in our consolidated balance sheets. We have corporate-owned life insurance policies on certain participants in our deferred compensation plans and other members of management. The cash surrender value of the corporate-owned life insurance policies is reported under the caption “Other invested assets” in our consolidated balance sheets. We use the equity method of accounting for investments in companies in which our ownership interest may enable us to influence the operating or financial decisions of the investee company. Our proportionate share of equity in net income of these unconsolidated affiliates is reported within net investment income. The equity method investments are reported under the caption “Other invested assets” in our consolidated balance sheets. Investment income is recorded when earned. All securities sold resulting in investment realized gains and losses are recorded on the trade date. Realized gains and losses are determined on the basis of the cost or amortized cost of the specific securities sold. We participate in securities lending programs whereby marketable securities in our investment portfolio are transferred to independent brokers or dealers in exchange for cash and securities collateral. Under Financial Accounting Standards Board (“FASB”) guidance related to accounting for transfers and servicing of financial assets and extinguishments of liabilities, we recognize the collateral as an asset, which is reported in other current assets on our consolidated balance sheets, and we record a corresponding liability for the obligation to return the collateral to the borrower, which is reported in other current liabilities. The securities on loan are reported in the applicable investment category on our consolidated balance sheets. Unrealized gains or losses on securities lending collateral are included in accumulated other comprehensive income as a separate component of shareholders’ equity. The market value of loaned securities and that of the collateral pledged can fluctuate in non-synchronized fashions. To the extent the loaned securities’ value appreciates faster or depreciates slower than the value of the collateral pledged, we are exposed to the risk of the shortfall. As a primary mitigating mechanism, the loaned securities and collateral pledged are marked to market on a daily basis and the shortfall, if any, is collected accordingly. Secondarily, the collateral level is set at 102% of the value of the loaned securities, which provides a cushion before any shortfall arises. The investment of the cash collateral is subject to market risk, which is managed by limiting the investments to higher quality and shorter duration instruments. Receivables: Receivables are reported net of amounts for expected credit losses. The allowance for doubtful accounts is based on historical collection trends, future forecasts and our judgment regarding the ability to collect specific accounts. Premium receivables include the uncollected amounts from insured groups, individuals and government programs. Premium receivables are reported net of an allowance for doubtful accounts of $152 and $142 at December 31, 2022 and 2021, respectively. Self-funded receivables include administrative fees, claims and other amounts due from fee-based customers. Self-funded receivables are reported net of an allowance for doubtful accounts of $68 and $50 at December 31, 2022 and 2021, respectively. Other receivables include pharmacy rebates, provider advances, claims recoveries, reinsurance receivables, proceeds due from brokers on investment trades, accrued investment income and other miscellaneous amounts due to us. These receivables are reported net of an allowance for doubtful accounts of $744 and $648 at December 31, 2022 and 2021, respectively. Income Taxes: We file a consolidated U.S. federal income tax return. Deferred income tax assets and liabilities are recognized for temporary differences between the financial statement and tax return basis of assets and liabilities based on enacted tax rates and laws and are reported net on our consolidated balance sheets. The deferred tax benefits of the deferred tax assets are recognized to the extent realization of such benefits is more likely than not. Deferred income tax expense or benefit generally represents the net change in deferred income tax assets and liabilities during the year, excluding the impact from amounts initially recorded for business combinations, if any, and amounts recorded to accumulated other comprehensive income. Current income tax expense represents the tax consequences of revenues and expenses currently taxable or deductible on various income tax returns for the year reported. The Internal Revenue Code subjects a U.S. shareholder to tax on Global Intangible Low-Taxed Income (“GILTI”) earned by certain foreign subsidiaries. We have elected to account for GILTI tax in the year the tax is incurred. The Inflation Reduction Act of 2022 includes a provision that imposes a new corporate alternative minimum tax (the “Corporate AMT”) that became effective for us beginning January 1, 2023. We have elected to account for the effects of the Corporate AMT on deferred tax assets and carryforwards and tax credits in the period they arise. Additionally, the Inflation Reduction Act of 2022 imposes an excise tax on the fair market value of net stock repurchases made after December 31, 2022. We do not believe the Corporate AMT will have a material impact on our consolidated financial position, results of operations, cash flows or related disclosures. We account for income tax contingencies in accordance with FASB guidance that contains a model to address uncertainty in tax positions and clarifies the accounting for income taxes by prescribing a minimum recognition threshold, which all income tax positions must achieve before being recognized in the financial statements. Property and Equipment: Property and equipment is recorded at cost, net of accumulated depreciation. Depreciation is computed principally by the straight-line method over estimated useful lives ranging from fifteen to thirty years for buildings and improvements, three to five years for computer equipment and software, and the lesser of the remaining life of the building lease, if any, or seven years for furniture and other equipment. Leasehold improvements are depreciated over the term of the related lease. Certain costs related to the development or purchase of internal-use software are capitalized and amortized over estimated useful lives ranging from three to ten years. Goodwill and Other Intangible Assets: FASB guidance requires business combinations to be accounted for using the acquisition method of accounting, and it also specifies the types of acquired intangible assets that are required to be recognized and reported separately from goodwill. Goodwill represents the excess of the cost of acquisition over the fair value of net assets acquired. Other intangible assets represent the values assigned to customer relationships, provider and hospital networks, Blue Cross and Blue Shield and other trademarks, licenses and other agreements, such as non-compete agreements. Goodwill and other intangible assets are allocated to reportable segments based on the relative fair value of the components of the businesses acquired. Goodwill and other intangible assets with indefinite lives are not amortized but are tested for impairment at least annually. Goodwill and other intangible assets are allocated to reporting units for purposes of the annual goodwill impairment test. Other intangible assets with indefinite lives, such as trademarks, are tested for impairment separately. We complete our annual impairment tests of existing goodwill and other intangible assets with indefinite lives during the fourth quarter of each year. Our impairment tests require us to make assumptions and judgments regarding the estimated fair value of our reporting units, including goodwill and other intangible assets with indefinite lives. Certain interim impairment tests are also performed when potential impairment indicators exist or changes in our business or other triggering events occur. FASB guidance allows for qualitative assessments of whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount for purposes of a goodwill impairment analysis and whether it is more likely than not that an indefinite-lived intangible asset is impaired for purposes of an indefinite-lived intangible asset impairment analysis. Estimated fair values developed based on our assumptions and judgments might be different if other reasonable assumptions and estimates were to be used. Qualitative analysis involves assessing situations and developments that could affect key drivers used to evaluate whether the fair value of our goodwill and indefinite-lived intangible assets are impaired. Our procedures include assessing our financial performance, macroeconomic conditions, industry and market considerations, various asset specific factors, and entity specific events. Quantitative analysis must be performed if qualitative analyses are not conclusive. Entities also have the option to bypass the assessment of qualitative factors and proceed directly to performing quantitative analyses. Fair value for purposes of a quantitative goodwill impairment test is calculated using a blend of the projected income and market valuation approaches. The projected income approach is developed using assumptions about future revenue, expenses and net income derived from our internal planning process. Our assumed discount rate is based on our industry’s weighted-average cost of capital and reflects volatility associated with the cost of equity capital. Market valuations include market comparisons to publicly traded companies in our industry and are based on observed multiples of certain measures including revenue; earnings before interest, taxes, depreciation and amortization (“EBITDA”); and book value of invested capital. A goodwill impairment loss is recognized to the extent that the carrying amount exceeds the asset’s fair value. This determination consists of a one-step test comparing the fair value of a reporting unit, including goodwill, to its carrying amount. If the carrying amount of a reporting unit exceeds its fair value, an impairment loss is recognized. This goodwill impairment loss is equal to the excess of the reporting unit’s carrying amount over its fair value. Fair value for purposes of a quantitative impairment test for indefinite-lived intangible assets is estimated using a projected income approach. We recognize an impairment loss when the estimated fair value of indefinite-lived intangible assets is less than the carrying value. If significant impairment indicators are noted relative to other intangible assets subject to amortization, we may be required to record impairment losses against future income. Derivative Financial Instruments: We primarily invest in the following types of derivative financial instruments: interest rate swaps, futures, forward contracts, put and call options, collars, swaptions, embedded derivatives and warrants. Derivatives embedded within non-derivative instruments, such as options embedded in convertible fixed maturity securities, are bifurcated from the host instrument when the embedded derivative is not clearly and closely related to the host instrument. Our use of derivatives is limited by statutes and regulations promulgated by the various regulatory bodies to which we are subject, and by our own derivative policy. Our derivative use is generally limited to hedging purposes, on an economic basis, and we generally do not use derivative instruments for speculative purposes. We have exposure to economic losses due to interest rate risk arising from changes in the level or volatility of interest rates. We attempt to mitigate our exposure to interest rate risk through active portfolio management, including rebalancing our existing portfolios of assets and liabilities, as well as changing the characteristics of investments to be purchased or sold in the future. In addition, derivative financial instruments are used to modify the interest rate exposure of certain liabilities or forecasted transactions. These strategies include the use of interest rate swaps and forward contracts, which are used to lock-in interest rates or to hedge, on an economic basis, interest rate risks associated with variable rate debt. We have used these types of instruments as designated hedges against specific liabilities. All investments in derivatives are recorded as assets or liabilities at fair value. If certain correlation, hedge effectiveness and risk reduction criteria are met, a derivative may be specifically designated as a hedge of exposure to changes in fair value or cash flow. The accounting for changes in the fair value of a derivative depends on the intended use of the derivative and the nature of any hedge designation thereon. Amounts excluded from the assessment of hedge effectiveness, if any, are reported in results of operations immediately. If the derivative is not designated as a hedge, the gain or loss resulting from the change in the fair value of the derivative is recognized in results of operations in the period of change. Cash flows associated with the settlement of non-designated derivatives are shown on a net basis in investing activity in our consolidated statements of cash flow. From time to time, we may also purchase derivatives to hedge, on an economic basis, our exposure to foreign currency exchange fluctuations associated with the operations of certain of our subsidiaries. We generally use futures or forward contracts for these transactions. We generally do not designate these contracts as hedges and, accordingly, the changes in fair value of these derivatives are recognized in results of operations immediately. Credit exposure associated with non-performance by the counterparties to derivative instruments is generally limited to the uncollateralized fair value of the asset related to instruments recognized in the consolidated balance sheets. We attempt to mitigate the risk of non-performance by selecting counterparties with high credit ratings and monitoring their creditworthiness and by diversifying derivatives among multiple counterparties. At December 31, 2022, we believe there were no material concentrations of credit risk with any individual counterparty. We generally enter into master netting agreements, which reduce credit risk by permitting net settlement of transactions with the same counterparty. Certain of our derivative agreements also contain credit support provisions that require us or the counterparty to post collateral if there are declines in the derivative fair value or our credit rating. The derivative assets and derivative liabilities are reported at their fair values net of collateral and netting by the counterparty. Retirement Benefits: We recognize the funded status of pension and other postretirement benefit plans on the consolidated balance sheets based on fiscal-year-end measurements of plan assets and benefit obligations. Prepaid pension benefits represent prepaid costs related to defined benefit pension plans and are reported with other noncurrent assets. Postretirement benefits represent outstanding obligations for retiree medical, life, vision and dental benefits. Liabilities for pension and other postretirement benefits are reported with noncurrent assets, current liabilities and noncurrent liabilities based on the amount by which the actuarial present value of benefits payable in the next twelve months included in the benefit obligation exceeds the fair value of plan assets. We determine the expected return on plan assets using the calculated value of plan assets, which recognizes changes in the fair value of plan assets in a systematic manner over three years. We apply a corridor approach to amortize unrecognized actuarial gains or losses. Under this approach, only accumulated net actuarial gains or losses in excess of 10% of the greater of the projected benefit obligation or the fair value of plan assets are amortized over the average remaining service or lifetime of the workforce as a component of net periodic benefit cost. The discount rate reflects the current rate at which the pension liabilities could be effectively settled at the end of the year based on our most recent measurement date. We use the annual spot rate approach for setting our discount rate. Under the spot rate approach, individual spot rates from a full yield curve of published rates are used to discount each plan’s cash flows to determine the plan’s obligations. The assumed healthcare cost trend rates used to measure the expected cost of other postretirement benefits are based on an initial assumed healthcare cost trend rate declining to an ultimate healthcare cost trend rate over a select number of years. Medical Claims Payable: Liabilities for medical claims payable include estimated provisions for incurred but not paid claims on an undiscounted basis, as well as estimated provisions for expenses related to the processing of claims. Incurred but not paid claims include (1) an estimate for claims that are incurred but not reported, as well as claims reported to us but not yet processed through our systems; and (2) claims reported to us and processed through our systems but not yet paid. Liabilities for both claims incurred but not reported and reported but not yet processed through our systems are determined in the aggregate, employing actuarial methods that are commonly used by health insurance actuaries and meet Actuarial Standards of Practice. Our reserving practice for claim liabilities is to consistently recognize the appropriate amount of reserve within a level of confidence required by Actuarial Standards of Practice. We determine the amount of the liability for incurred but not paid claims by following a detailed actuarial process that uses both historical claim payment patterns as well as emerging medical cost trends to project our best estimate of claim liabilities. Under this process, historical paid claims data is formatted into “claim triangles,” which compare claim incurred dates to the dates of claim payments. This information is analyzed to create “completion factors” that represent the average percentage of total incurred claims that have been paid through a given date after being incurred. Completion factors are applied to claims paid through the period-end date to estimate the ultimate claim expense incurred for the period. Actuarial estimates of incurred but not paid claim liabilities are then determined by subtracting the actual paid claims from the estimate of the ultimate incurred claims. For the most recent incurred months (typically the most recent two months), the percentage of claims paid for claims incurred in those months is generally low. This makes the completion factor methodology less reliable for such months. Therefore, incurred claims for recent months are not projected from historical completion and payment patterns; rather, they are projected by estimating the claims expense for those months based on recent claims expense levels and healthcare trend levels (“trend factors”). We regularly review and set assumptions regarding cost trends and utilization when initially establishing claim liabilities. We continually monitor and adjust the claims liability and benefit expense based on subsequent paid claims activity. If it is determined that our assumptions regarding cost trends and utilization are materially different than actual results, our income statement and financial position could be impacted in future periods. Premium deficiencies are recognized when it is probable that expected claims and administrative expenses will exceed future premiums on existing medical insurance contracts without consideration of investment income. Determination of premium deficiencies for longer duration life and disability contracts includes consideration of investment income. For purposes of premium deficiencies, contracts are deemed to be either short or long duration and are grouped in a manner consistent with our method of acquiring, servicing and measuring the profitability of such contracts. Once established, premium deficiencies are released commensurate with actual claims experience over the remaining life of the contract. No premium deficiencies were established at December 31, 2022 or 2021. Benefit expense includes incurred medical claims as well as quality improvement expenses for our risk-based members. Quality improvement activities are those designed to improve member health outcomes, prevent hospital readmissions and improve patient safety. They also include expenses for wellness and health promotion provided to our members. Other Policyholder Liabilities: Other policyholder liabilities include rate stabilization reserves associated with retrospectively rated insurance contracts and certain case-specific reserves. Other policyholder liabilities also include liabilities for premium refunds based upon the minimum medical loss ratio (“MLR”), the relative health risk of members, and other contractual or regulatory requirements. Rate stabilization reserves represent accumulated premiums that exceed what customers owe us based on actual claim experience. The timing of payment of these retrospectively rated refunds is based on the contractual terms with our customers and can vary from period to period based on the specific contractual requirements. We are required to meet certain minimum MLR thresholds prescribed by the Patient Protection and Affordable Care Act and the Health Care and Education Reconciliation Act of 2010, as amended (collectively the “ACA”). If we do not meet or exceed the minimum MLR thresholds specified by the ACA, we are required to pay rebates to certain customers. Minimum MLR rebates are calculated by subsidiary, state and applicable line of business in accordance with regulations issued by the Department of Health and Human Services (“HHS”). Such calculations are made using estimated calendar year medical loss expense and premiums, as defined by HHS. We follow HHS guidelines for determining the types of expenses that may be included in our minimum MLR rebate calculations, which differ from benefit expense and premiums as reported in our consolidated financial statements prepared in conformity with GAAP. Certain amounts reported as expense in our consolidated GAAP financial statements may be reported as a reduction of premiums in accordance with HHS regulations. In addition, profit amounts included in our payments to third-party administrative service providers are recorded as benefit expense in our consolidated GAAP financial statements, while HHS does not allow for the inclusion of these expenses within the medical loss expense for purposes of calculating minimum MLR. Reserves for Future Policy Benefits: Reserves for future policy benefits include liabilities for life and long-term disability insurance policy benefits based upon interest, mortality and morbidity assumptions from published actuarial tables, modified based upon our experience. Future policy benefits also include liabilities for insurance policies for which some of the premiums received in earlier years are intended to pay anticipated benefits to be incurred in future years. Future policy benefits are continually monitored and reviewed, and when reserves are adjusted, differences are reflected in benefit expense. We believe that our liabilities for future policy benefits, along with future premiums received, are adequate to satisfy our ultimate benefit liability; however, these estimates are inherently subject to a number of variable circumstances. Consequently, the actual results could differ materially from the amounts recorded in our consolidated financial statements. Revenue Recognition: Premiums for risk-based contracts are recognized as revenue over the period insurance coverage is provided, and, if applicable, net of amounts recognized for MLR rebates, risk adjustment, reinsurance and risk corridor under contractual premium stabilization arrangements, the ACA or other regulatory requirements. Premiums may also include performance incentives and penalties, which are recognized based on contractual terms. We estimate amounts receivable and payable under these contractual terms, and to the extent that such estimated amounts vary from the final amounts paid, the adjustments are included in earnings in the period of final settlement. Premium payments from contracted government agencies are based on eligibility lists produced by the government agencies. Premiums related to the unexpired contractual coverage periods are reflected in the accompanying consolidated balance sheets as unearned income. Premiums include revenue adjustments for retrospectively rated contracts where revenue is based on the estimated loss experience of the contract. Premium rates for certain lines of business are subject to approval by the Department of Insurance of each respective state. Additionally, delays in annual premium rate changes from contracted government agencies require that we defer the recognition of any increases to the period in which the premium rates become final. The value of the impact can be significant in the period in which it is recognized depending on the magnitude of the premium rate increase, the membership to which it applies and the length of the delay between the effective date of the rate increase and the final contract date. Premium rate decreases are recognized in the period the change in premium rate becomes effective and the change in the rate is known, which may be prior to the period when the contract amendment affecting the rate is finalized. Administrative fees and other revenue include revenue from certain group contracts that provide for the group to be at risk for all, or with supplemental insurance arrangements, a portion, of their claims experience. We charge these fee-based groups an administrative fee, which is based on the number of members in a group and the group’s claim experience. In addition, administrative fees and other revenue include amounts received for the administration of Medicare, certain other government programs, and administrative services arrangements of our Carelon (Diversified Business Group) subsidiaries, now known as Carelon. Generally, these fee-based arrangements include services which constitute a single suite of services provided and for which consideration is based upon an agreed-upon rate, regardless of the amount of services provided in a given period. As with premiums, these fee-based arrangements may include terms with retroactive rate or membership adjustments, performance incentives and penalties, each of which is a form of variable consideration within the transaction price. As such, these fee-based arrangements contain a single performance obligation that constitutes a series, and revenue is recognized over time as the services are performed. All benefit payments under these programs are excluded from benefit expense. The determination of whether services are distinct performance obligations that should be accounted for separately or combined as one unit of accounting may require significant judgment. The estimation of variable consideration to be recognized requires significant judgment in the determination of the level of achievement of performance incentives, service level achievements subject to performance penalties, and the completion level of tasks subject to implementation fees. Product revenue includes revenue for services performed by our CarelonRx PBM for unaffiliated PBM customers. Unaffiliated PBM customers include our fee-based groups that have contracted with CarelonRx for PBM services and third-party health plans. Product revenues and costs of goods sold for our affiliated health plans are eliminated in consolidation. Product revenue for PBM services is recognized using the gross method at the negotiated contract price when CarelonRx has concluded that it is the principal and it controls the services before prescription drugs are transferred to the customer. CarelonRx determined it is the principal due to its contractual rights to design and develop a listing of prescription drugs offered to the customer (formulary management); its control over establishing the pharmacy network available to the customer to have its prescription fulfilled (network management); and its discretion over establishing the pricing for prescription drugs. Overall, control over these activities indicate CarelonRx is primarily responsible for fulfilling the promise to provide PBM services. Product revenue includes ingredient costs (net of any rebates or discounts), including any co-payments made by or on behalf of the customer, and administrative fees. CarelonRx recognizes revenue when control of the prescription drugs is transferred to customers, in an amount it expects to be entitled to in exchange for the products or services provided. For our non-risk-based contracts, we had no material contract assets, contract liabilities or deferred contract costs recorded on our consolidated balance sheet at December 31, 2022. Revenue recognized in 2022 and 2021 from performance obligations related to prior years, such as due to changes in transaction price, was not material. For contracts that have an original expected duration of greater than one year, revenue expected to be recognized in future periods related to unfulfilled contractual performance obligations and contracts with variable consideration related to undelivered performance obligations is not material. Cost of Products Sold: CarelonRx’s cost of products sold includes the cost of prescription drugs dispensed to unaffiliated PBM customers (net of rebates or discounts). Cost of products sold includes per-claim administrative fees for prescription fulfillment by its vendor and certain CarelonRx direct costs related to sales and administration of customer contracts. Share-Based Compensation: Our current compensation philosophy provides for share-based compensation, including stock options, restricted stock awards and an employee stock purchase plan. Stock options are granted for a fixed number of shares with an exercise price at least equal to the fair value of the shares at the date of the grant. Restricted stock awards are issued at the fair value of the stock on the grant date. The employee stock purchase plan allows for a purchase price per share which is 90% of the fair value of a share of common stock on the lower of the first or last trading day of the plan quarter. The employee stock purchase plan discount is recognized as compensation expense based on GAAP guidance. All other share-based payments to employees are recognized as compensation expense in our consolidated statements of income based on their fair values. Additionally, excess tax benefits, which result from actual tax benefits realized when awards vest or options are exercised exceeding deferred tax benefits previously recognized based on grant date fair value, are recognized as tax benefits in the consolidated statements of income. Advertising and Marketing Costs: We use print, broadcast and other advertising to promote our products and to develop our corporate image. We market our products through direct marketing activities and an extensive network of independent agents, brokers and retail partnerships for Individual and Medicare customers, and for certain Group risk-based customers with a smaller employee base. Products for Group risk-based customers with a larger employee base are generally sold through independent brokers or consultants retained by the customer who work with industry specialists from our in-house sales force. In the Individual and Group markets, we offer products through state or federally facilitated marketplaces, or Public Exchanges, and off-exchange products. The cost of advertising and marketing for product promotion is expensed as incurred, while advertising and marketing costs associated with our corporate image are expensed when first aired. Total advertising and marketing expense was $511, $588 and $558 for the years ended December 31, 2022, 2021 and 2020, respectively. Health Insurance Provider Fee: The ACA imposed an annual Health Insurance Provider Fee (“HIP Fee”) on health insurers that wrote certain types of health insurance on U.S. risks, which was permanently repealed effective January 1, 2021. The HIP Fee was non-deductible for federal income tax purposes. Our affected products were priced to cover the increased selling, general and administrative and income tax expenses associated with the HIP Fee when it was in effect. The HIP Fee was $15,523 for 2020 and was permanently eliminated beginning in 2021. For the year ended December 31, 2020, we recognized $1,570 as selling, general and administrative expense related to the HIP Fee. Leases: We lease office space and certain computer and related equipment under noncancelable operating leases. We determine whether an arrangement is or contains a lease at its inception. We recognize lease liabilities based on the present value of the minimum lease payments not yet paid by using the lease term, any amounts probable of being owed under any residual value guarantees and the discount rate determined at lease commencement. As our leases do not generally provide an implicit rate, we use our incremental secured borrowing rate commensurate with the underlying lease terms to determine the present value of our lease payments. Our lease liabilities may include amounts for options to extend or terminate a lease when it is reasonably certain that we will exercise that option. We recognize operating right-of-use (“ROU”) assets at an amount equal to the lease liability adjusted for prepaid or accrued rent, the remaining balance of any lease incentives and unamortized initial direct costs. The operating lease liabilities are reported in other current liabilities and other noncurrent liabilities and the related ROU assets are reported in other noncurrent assets on our consolidated balance sheets. Lease expense for our operating leases is calculated on a straight-line basis over the lease term and is reported in selling, general and administrative expense on our consolidated statements of income. For our office space leases, we account for the lease and non-lease components (such as common area maintenance) as a single lease component. We also do not recognize a lease liability or ROU asset for our office space leases whose lease terms, at commencement, are twelve months or less and that do not include a purchase option or option to extend that we are reasonably certain to exercise. We assess our ROU assets for impairment when there are indicators of impairment and compare the carrying amount of the ROU asset to its estimated undiscounted future cash flows. If the estimated undiscounted future cash flows are less than the carrying amount of the ROU asset, an impairment calculation is performed. An impairment loss is recorded for the difference of the ROU asset’s carrying value that exceeds its estimated discounted cash flows. During the years ended December 31, 2022, 2021 and 2020, we recorded $34, $136 and $258, respectively, for impairment and abandonment of ROU assets. See Note 18, “Leases” for additional information about the ROU asset impairment and abandonment charges. Earnings per Share: Earnings per share amounts, on a basic and diluted basis, have been calculated based upon the weighted-average common shares outstanding for the period. Basic earnings per share excludes dilution and is computed by dividing income available to common shareholders by the weighted-average number of common shares outstanding for the period. Diluted earnings per share may include the dilutive effect of stock options, restricted stock and convertible debentures, using the treasury stock method. The treasury stock method assumes exercise of stock options and vesting of restricted stock, with the assumed proceeds used to purchase common stock at the average market price for the period. The difference between the number of shares assumed issued and the number of shares assumed purchased represents the dilutive shares. Recently Adopted Accounting Guidance: In January 2021, the FASB issued Accounting Standards Update No. 2021-01, Reference Rate Reform (Topic 848) (“ASU 2021-01”). The amendments in ASU 2021-01 provide optional expedients and exceptions for applying GAAP to contract modifications and hedging relationships, subject to meeting certain criteria, that reference the London Interbank Offered Rate (“LIBOR”) or another reference rate expected to be discontinued because of the reference rate reform. The provisions must be applied at a Topic, Subtopic, or Industry Subtopic level for all transactions other than derivatives, which may be applied at a hedging relationship level. We adopted ASU 2021-01 on January 7, 2021, and the adoption did not have an impact on our consolidated financial position, results of operations or cash flows. In October 2020, the FASB issued Accounting Standards Update No. 2020-08, Codification Improvements to Subtopic 310-20, Receivables—Nonrefundable Fees and Other Costs (“ASU 2020-08”). The amendments in ASU 2020-08 clarify when an entity should assess whether a callable debt security is within the scope of accounting guidance, which impacts the amortization period for nonrefundable fees and other costs. ASU 2020-08 became effective for interim and annual reporting periods beginning after December 15, 2020. The amendments were applied on a prospective basis as of the beginning of the period of adoption for existing or newly purchased callable debt securities. We adopted ASU 2020-08 on January 1, 2021, and the adoption did not have an impact on our consolidated financial position, results of operations or cash flows. In August 2020, the FASB issued Accounting Standards Update No. 2020-06, Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging—Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity (“ASU 2020-06”). The amendments eliminate two of the three accounting models that require separate accounting for convertible features of debt securities, simplify the contract settlement assessment for equity classification, require the use of the if-converted method for all convertible instruments in the diluted earnings per share calculation and expand disclosure requirements. The amendments became effective for our annual and interim reporting periods beginning after December 15, 2021. We adopted ASU 2020-06 on January 1, 2022 using the modified retrospective transition method, which resulted in an increase to our reported debt outstanding of $31, a decrease to our deferred tax liabilities of $8, and a corresponding cumulative-effect reduction to our opening retained earnings of $23, eliminating the bifurcation of the embedded conversion option; these amounts were not material to our overall consolidated financial position. The adoption of ASU 2020-06 did not have an impact on our results of operations or our consolidated cash flows. Use of the if-converted method did not have an impact on our overall earnings per share calculation. In December 2019, the FASB issued Accounting Standards Update No. 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes (“ASU 2019-12”). The amendments in ASU 2019-12 remove certain exceptions to the general principles in Accounting Standards Codification Topic 740. The amendments also clarify and amend existing guidance to improve consistent application. The amendments became effective for our annual reporting periods beginning after December 15, 2020. The transition method (retrospective, modified retrospective, or prospective basis) related to the amendments depends on the applicable guidance, and all amendments for which there is no transition guidance specified are to be applied on a prospective basis. We adopted ASU 2019-12 on January 1, 2021, and the adoption did not have an impact on our consolidated financial position, results of operations or cash flows. Recent Accounting Guidance Not Yet Adopted: 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 extended the original effective date by one year, with the amendments required for our interim and annual reporting periods beginning after December 15, 2022. This standard requires the Company to review cash flow assumptions for its long-duration insurance contracts at least annually and recognize the effect of changes in future cash flow assumptions in net income. This standard also requires the Company to update discount rate assumptions quarterly and recognize the effect of changes in these assumptions in other comprehensive income. The rate used to discount the Company’s reserves for future policy benefits will be based on an estimate of the yield for an upper-medium grade fixed-income instrument with a duration profile matching that of the Company’s liabilities. In addition, this standard changes the amortization method for deferred acquisition costs. The Company adopted the new standard on January 1, 2023, using the modified retrospective transition method for changes to the liability for future policy benefits and deferred acquisition costs as of the earliest period presented, January 1, 2021. The adoption did not have a material impact on our consolidated financial position, results of operations, cash flows, or related disclosures. There were no other new accounting pronouncements that were issued or became effective during the year ended December 31, 2022 that had, or are expected to have, a material impact on our financial position, results of operations, cash flows or financial statement disclosures.

Certain of our subsidiaries operate outside of the United States and have functional currencies other than the U.S. dollar (“USD”). We translate the assets and liabilities of those subsidiaries to USD using the exchange rate in effect at the end of the period. We translate the revenues and expenses of those subsidiaries to USD using the average exchange rates in effect during the period. The net effect of these translation adjustments is included in “Foreign currency translation adjustments” in our consolidated statements of comprehensive income.

Cash and Cash Equivalents: Cash and cash equivalents includes available cash and all highly liquid investments with maturities of three months or less when purchased. We control a number of bank accounts that are used exclusively to hold customer funds for the administration of customer benefits, and we have cash and cash equivalents on deposit to meet certain regulatory requirements. These amounts totaled $258 and $173 at December 31, 2022 and 2021, respectively, and are included in the cash and cash equivalents line on our consolidated balance sheets.

Investments: We classify fixed maturity securities in our investment portfolio as “available-for-sale” and report those securities at fair value. Certain fixed maturity securities are available to support current operations and, accordingly, we classify such investments as current assets without regard to their contractual maturity. Investments used to satisfy contractual, regulatory or other requirements are classified as long-term, without regard to contractual maturity.

If a fixed maturity security is in an unrealized loss position and we have the intent to sell the fixed maturity security, or it is more likely than not that we will have to sell the fixed maturity security before recovery of its amortized cost basis, we write down the fixed maturity security’s cost basis to fair value and record an impairment loss in our consolidated statements of income. For impaired fixed maturity securities that we do not intend to sell or if it is more likely than not that we will not have to sell such securities, but we expect that we will not fully recover the amortized cost basis, we recognize the credit component of the impairment as an allowance for credit loss in our consolidated balance sheets and record an impairment loss in our consolidated statements of income. The non-credit component of the impairment is recognized in accumulated other comprehensive loss. Furthermore, unrealized losses entirely caused by non-credit-related factors related to fixed maturity securities for which we expect to fully recover the amortized cost basis continue to be recognized in accumulated other comprehensive loss.

The credit component of an impairment is determined primarily by comparing the net present value of projected future cash flows with the amortized cost basis of the fixed maturity security. The net present value is calculated by discounting our best estimate of projected future cash flows at the effective interest rate implicit in the fixed maturity security at the date of purchase. For mortgage-backed and asset-backed securities, cash flow estimates are based on assumptions regarding the underlying collateral, including prepayment speeds, vintage, type of underlying asset, geographic concentrations, default rates, recoveries and changes in value. For all other securities, cash flow estimates are driven by assumptions regarding probability of default, including changes in credit ratings and estimates regarding timing and amount of recoveries associated with a default.

We use the equity method of accounting for investments in companies in which our ownership interest may enable us to influence the operating or financial decisions of the investee company. Our proportionate share of equity in net income of these unconsolidated affiliates is reported within net investment income. The equity method investments are reported under the caption “Other invested assets” in our consolidated balance sheets.

We participate in securities lending programs whereby marketable securities in our investment portfolio are transferred to independent brokers or dealers in exchange for cash and securities collateral. Under Financial Accounting Standards Board (“FASB”) guidance related to accounting for transfers and servicing of financial assets and extinguishments of liabilities, we recognize the collateral as an asset, which is reported in other current assets on our consolidated balance sheets, and we record a corresponding liability for the obligation to return the collateral to the borrower, which is reported in other current liabilities. The securities on loan are reported in the applicable investment category on our consolidated balance sheets. Unrealized gains or losses on securities lending collateral are included in accumulated other comprehensive income as a separate component of shareholders’ equity. The market value of loaned securities and that of the collateral pledged can fluctuate in non-synchronized fashions. To the extent the loaned securities’ value appreciates faster or depreciates slower than the value of the collateral pledged, we are exposed to the risk of the shortfall. As a primary mitigating mechanism, the loaned securities and collateral pledged are marked to market on a daily basis and the shortfall, if any, is collected accordingly. Secondarily, the collateral level is set at 102% of the value of the loaned securities, which provides a cushion before any shortfall arises. The investment of the cash collateral is subject to market risk, which is managed by limiting the investments to higher quality and shorter duration instruments.

Income Taxes: We file a consolidated U.S. federal income tax return. Deferred income tax assets and liabilities are recognized for temporary differences between the financial statement and tax return basis of assets and liabilities based on enacted tax rates and laws and are reported net on our consolidated balance sheets. The deferred tax benefits of the deferred tax assets are recognized to the extent realization of such benefits is more likely than not. Deferred income tax expense or benefit generally represents the net change in deferred income tax assets and liabilities during the year, excluding the impact

The Inflation Reduction Act of 2022 includes a provision that imposes a new corporate alternative minimum tax (the “Corporate AMT”) that became effective for us beginning January 1, 2023. We have elected to account for the effects of the Corporate AMT on deferred tax assets and carryforwards and tax credits in the period they arise. Additionally, the Inflation Reduction Act of 2022 imposes an excise tax on the fair market value of net stock repurchases made after December 31, 2022. We do not believe the Corporate AMT will have a material impact on our consolidated financial position, results of operations, cash flows or related disclosures.

Property and Equipment: Property and equipment is recorded at cost, net of accumulated depreciation. Depreciation is computed principally by the straight-line method over estimated useful lives ranging from fifteen to thirty years for buildings and improvements, three to five years for computer equipment and software, and the lesser of the remaining life of the building lease, if any, or seven years for furniture and other equipment. Leasehold improvements are depreciated over the term of the related lease. Certain costs related to the development or purchase of internal-use software are capitalized and amortized over estimated useful lives ranging from three to ten years.

Goodwill and Other Intangible Assets: FASB guidance requires business combinations to be accounted for using the acquisition method of accounting, and it also specifies the types of acquired intangible assets that are required to be recognized and reported separately from goodwill. Goodwill represents the excess of the cost of acquisition over the fair value of net assets acquired. Other intangible assets represent the values assigned to customer relationships, provider and hospital networks, Blue Cross and Blue Shield and other trademarks, licenses and other agreements, such as non-compete agreements. Goodwill and other intangible assets are allocated to reportable segments based on the relative fair value of the components of the businesses acquired.

Goodwill and other intangible assets with indefinite lives are not amortized but are tested for impairment at least annually. Goodwill and other intangible assets are allocated to reporting units for purposes of the annual goodwill impairment test. Other intangible assets with indefinite lives, such as trademarks, are tested for impairment separately. We complete our annual impairment tests of existing goodwill and other intangible assets with indefinite lives during the fourth quarter of each year. Our impairment tests require us to make assumptions and judgments regarding the estimated fair value of our reporting units, including goodwill and other intangible assets with indefinite lives. Certain interim impairment tests are also performed when potential impairment indicators exist or changes in our business or other triggering events occur.

FASB guidance allows for qualitative assessments of whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount for purposes of a goodwill impairment analysis and whether it is more likely than not that an indefinite-lived intangible asset is impaired for purposes of an indefinite-lived intangible asset impairment analysis. Estimated fair values developed based on our assumptions and judgments might be different if other reasonable assumptions and estimates were to be used. Qualitative analysis involves assessing situations and developments that could affect key drivers used to evaluate whether the fair value of our goodwill and indefinite-lived intangible assets are impaired. Our procedures include assessing our financial performance, macroeconomic conditions, industry and market considerations, various asset specific factors, and entity specific events.

Quantitative analysis must be performed if qualitative analyses are not conclusive. Entities also have the option to bypass the assessment of qualitative factors and proceed directly to performing quantitative analyses. Fair value for purposes of a quantitative goodwill impairment test is calculated using a blend of the projected income and market valuation approaches. The projected income approach is developed using assumptions about future revenue, expenses and net income derived from our internal planning process. Our assumed discount rate is based on our industry’s weighted-average cost of capital and reflects volatility associated with the cost of equity capital. Market valuations include market comparisons to publicly traded

A goodwill impairment loss is recognized to the extent that the carrying amount exceeds the asset’s fair value. This determination consists of a one-step test comparing the fair value of a reporting unit, including goodwill, to its carrying amount. If the carrying amount of a reporting unit exceeds its fair value, an impairment loss is recognized. This goodwill impairment loss is equal to the excess of the reporting unit’s carrying amount over its fair value.

Fair value for purposes of a quantitative impairment test for indefinite-lived intangible assets is estimated using a projected income approach. We recognize an impairment loss when the estimated fair value of indefinite-lived intangible assets is less than the carrying value. If significant impairment indicators are noted relative to other intangible assets subject to amortization, we may be required to record impairment losses against future income.

Derivative Financial Instruments: We primarily invest in the following types of derivative financial instruments: interest rate swaps, futures, forward contracts, put and call options, collars, swaptions, embedded derivatives and warrants. Derivatives embedded within non-derivative instruments, such as options embedded in convertible fixed maturity securities, are bifurcated from the host instrument when the embedded derivative is not clearly and closely related to the host instrument. Our use of derivatives is limited by statutes and regulations promulgated by the various regulatory bodies to which we are subject, and by our own derivative policy. Our derivative use is generally limited to hedging purposes, on an economic basis, and we generally do not use derivative instruments for speculative purposes.

We have exposure to economic losses due to interest rate risk arising from changes in the level or volatility of interest rates. We attempt to mitigate our exposure to interest rate risk through active portfolio management, including rebalancing our existing portfolios of assets and liabilities, as well as changing the characteristics of investments to be purchased or sold in the future. In addition, derivative financial instruments are used to modify the interest rate exposure of certain liabilities or forecasted transactions. These strategies include the use of interest rate swaps and forward contracts, which are used to lock-in interest rates or to hedge, on an economic basis, interest rate risks associated with variable rate debt. We have used these types of instruments as designated hedges against specific liabilities.

All investments in derivatives are recorded as assets or liabilities at fair value. If certain correlation, hedge effectiveness and risk reduction criteria are met, a derivative may be specifically designated as a hedge of exposure to changes in fair value or cash flow. The accounting for changes in the fair value of a derivative depends on the intended use of the derivative and the nature of any hedge designation thereon. Amounts excluded from the assessment of hedge effectiveness, if any, are reported in results of operations immediately. If the derivative is not designated as a hedge, the gain or loss resulting from the change in the fair value of the derivative is recognized in results of operations in the period of change. Cash flows associated with the settlement of non-designated derivatives are shown on a net basis in investing activity in our consolidated statements of cash flow.

From time to time, we may also purchase derivatives to hedge, on an economic basis, our exposure to foreign currency exchange fluctuations associated with the operations of certain of our subsidiaries. We generally use futures or forward contracts for these transactions. We generally do not designate these contracts as hedges and, accordingly, the changes in fair value of these derivatives are recognized in results of operations immediately.

Credit exposure associated with non-performance by the counterparties to derivative instruments is generally limited to the uncollateralized fair value of the asset related to instruments recognized in the consolidated balance sheets. We attempt to mitigate the risk of non-performance by selecting counterparties with high credit ratings and monitoring their creditworthiness and by diversifying derivatives among multiple counterparties. At December 31, 2022, we believe there were no material concentrations of credit risk with any individual counterparty.

We generally enter into master netting agreements, which reduce credit risk by permitting net settlement of transactions with the same counterparty. Certain of our derivative agreements also contain credit support provisions that require us or the counterparty to post collateral if there are declines in the derivative fair value or our credit rating. The derivative assets and derivative liabilities are reported at their fair values net of collateral and netting by the counterparty.

benefits represent prepaid costs related to defined benefit pension plans and are reported with other noncurrent assets. Postretirement benefits represent outstanding obligations for retiree medical, life, vision and dental benefits. Liabilities for pension and other postretirement benefits are reported with noncurrent assets, current liabilities and noncurrent liabilities based on the amount by which the actuarial present value of benefits payable in the next twelve months included in the benefit obligation exceeds the fair value of plan assets.

We determine the expected return on plan assets using the calculated value of plan assets, which recognizes changes in the fair value of plan assets in a systematic manner over three years. We apply a corridor approach to amortize unrecognized actuarial gains or losses. Under this approach, only accumulated net actuarial gains or losses in excess of 10% of the greater of the projected benefit obligation or the fair value of plan assets are amortized over the average remaining service or lifetime of the workforce as a component of net periodic benefit cost.

The discount rate reflects the current rate at which the pension liabilities could be effectively settled at the end of the year based on our most recent measurement date. We use the annual spot rate approach for setting our discount rate. Under the spot rate approach, individual spot rates from a full yield curve of published rates are used to discount each plan’s cash flows to determine the plan’s obligations.

Medical Claims Payable: Liabilities for medical claims payable include estimated provisions for incurred but not paid claims on an undiscounted basis, as well as estimated provisions for expenses related to the processing of claims. Incurred but not paid claims include (1) an estimate for claims that are incurred but not reported, as well as claims reported to us but not yet processed through our systems; and (2) claims reported to us and processed through our systems but not yet paid.

Liabilities for both claims incurred but not reported and reported but not yet processed through our systems are determined in the aggregate, employing actuarial methods that are commonly used by health insurance actuaries and meet Actuarial Standards of Practice. Our reserving practice for claim liabilities is to consistently recognize the appropriate amount of reserve within a level of confidence required by Actuarial Standards of Practice. We determine the amount of the liability for incurred but not paid claims by following a detailed actuarial process that uses both historical claim payment patterns as well as emerging medical cost trends to project our best estimate of claim liabilities. Under this process, historical paid claims data is formatted into “claim triangles,” which compare claim incurred dates to the dates of claim payments. This information is analyzed to create “completion factors” that represent the average percentage of total incurred claims that have been paid through a given date after being incurred. Completion factors are applied to claims paid through the period-end date to estimate the ultimate claim expense incurred for the period. Actuarial estimates of incurred but not paid claim liabilities are then determined by subtracting the actual paid claims from the estimate of the ultimate incurred claims.

For the most recent incurred months (typically the most recent two months), the percentage of claims paid for claims incurred in those months is generally low. This makes the completion factor methodology less reliable for such months. Therefore, incurred claims for recent months are not projected from historical completion and payment patterns; rather, they are projected by estimating the claims expense for those months based on recent claims expense levels and healthcare trend levels (“trend factors”).

We regularly review and set assumptions regarding cost trends and utilization when initially establishing claim liabilities. We continually monitor and adjust the claims liability and benefit expense based on subsequent paid claims activity. If it is determined that our assumptions regarding cost trends and utilization are materially different than actual results, our income statement and financial position could be impacted in future periods.

Premium deficiencies are recognized when it is probable that expected claims and administrative expenses will exceed future premiums on existing medical insurance contracts without consideration of investment income. Determination of premium deficiencies for longer duration life and disability contracts includes consideration of investment income. For purposes of premium deficiencies, contracts are deemed to be either short or long duration and are grouped in a manner consistent with our method of acquiring, servicing and measuring the profitability of such contracts. Once established, premium deficiencies are released commensurate with actual claims experience over the remaining life of the contract. No premium deficiencies were established at December 31, 2022 or 2021.

Other Policyholder Liabilities: Other policyholder liabilities include rate stabilization reserves associated with retrospectively rated insurance contracts and certain case-specific reserves. Other policyholder liabilities also include liabilities for premium refunds based upon the minimum medical loss ratio (“MLR”), the relative health risk of members, and other contractual or regulatory requirements. Rate stabilization reserves represent accumulated premiums that exceed what customers owe us based on actual claim experience. The timing of payment of these retrospectively rated refunds is based on the contractual terms with our customers and can vary from period to period based on the specific contractual requirements.

We are required to meet certain minimum MLR thresholds prescribed by the Patient Protection and Affordable Care Act and the Health Care and Education Reconciliation Act of 2010, as amended (collectively the “ACA”). If we do not meet or exceed the minimum MLR thresholds specified by the ACA, we are required to pay rebates to certain customers. Minimum MLR rebates are calculated by subsidiary, state and applicable line of business in accordance with regulations issued by the Department of Health and Human Services (“HHS”). Such calculations are made using estimated calendar year medical loss expense and premiums, as defined by HHS.

We follow HHS guidelines for determining the types of expenses that may be included in our minimum MLR rebate calculations, which differ from benefit expense and premiums as reported in our consolidated financial statements prepared in conformity with GAAP. Certain amounts reported as expense in our consolidated GAAP financial statements may be reported as a reduction of premiums in accordance with HHS regulations. In addition, profit amounts included in our payments to third-party administrative service providers are recorded as benefit expense in our consolidated GAAP financial statements, while HHS does not allow for the inclusion of these expenses within the medical loss expense for purposes of calculating minimum MLR.

Reserves for Future Policy Benefits: Reserves for future policy benefits include liabilities for life and long-term disability insurance policy benefits based upon interest, mortality and morbidity assumptions from published actuarial tables, modified based upon our experience. Future policy benefits also include liabilities for insurance policies for which some of the premiums received in earlier years are intended to pay anticipated benefits to be incurred in future years. Future policy benefits are continually monitored and reviewed, and when reserves are adjusted, differences are reflected in benefit expense.

Revenue Recognition: Premiums for risk-based contracts are recognized as revenue over the period insurance coverage is provided, and, if applicable, net of amounts recognized for MLR rebates, risk adjustment, reinsurance and risk corridor under contractual premium stabilization arrangements, the ACA or other regulatory requirements. Premiums may also include performance incentives and penalties, which are recognized based on contractual terms. We estimate amounts receivable and payable under these contractual terms, and to the extent that such estimated amounts vary from the final amounts paid, the adjustments are included in earnings in the period of final settlement. Premium payments from contracted government agencies are based on eligibility lists produced by the government agencies. Premiums related to the unexpired contractual coverage periods are reflected in the accompanying consolidated balance sheets as unearned income. Premiums include revenue adjustments for retrospectively rated contracts where revenue is based on the estimated loss experience of the contract. Premium rates for certain lines of business are subject to approval by the Department of Insurance of each respective state. Additionally, delays in annual premium rate changes from contracted government agencies require that we defer the recognition of any increases to the period in which the premium rates become final. The value of the impact can be significant in the period in which it is recognized depending on the magnitude of the premium rate increase, the membership to which it applies and the length of the delay between the effective date of the rate increase and the final contract date. Premium rate decreases are recognized in the period the change in premium rate becomes effective and the change in the rate is known, which may be prior to the period when the contract amendment affecting the rate is finalized.

groups an administrative fee, which is based on the number of members in a group and the group’s claim experience. In addition, administrative fees and other revenue include amounts received for the administration of Medicare, certain other government programs, and administrative services arrangements of our Carelon (Diversified Business Group) subsidiaries, now known as Carelon. Generally, these fee-based arrangements include services which constitute a single suite of services provided and for which consideration is based upon an agreed-upon rate, regardless of the amount of services provided in a given period. As with premiums, these fee-based arrangements may include terms with retroactive rate or membership adjustments, performance incentives and penalties, each of which is a form of variable consideration within the transaction price. As such, these fee-based arrangements contain a single performance obligation that constitutes a series, and revenue is recognized over time as the services are performed. All benefit payments under these programs are excluded from benefit expense.

The determination of whether services are distinct performance obligations that should be accounted for separately or combined as one unit of accounting may require significant judgment. The estimation of variable consideration to be recognized requires significant judgment in the determination of the level of achievement of performance incentives, service level achievements subject to performance penalties, and the completion level of tasks subject to implementation fees.

Product revenue includes revenue for services performed by our CarelonRx PBM for unaffiliated PBM customers. Unaffiliated PBM customers include our fee-based groups that have contracted with CarelonRx for PBM services and third-party health plans. Product revenues and costs of goods sold for our affiliated health plans are eliminated in consolidation. Product revenue for PBM services is recognized using the gross method at the negotiated contract price when CarelonRx has concluded that it is the principal and it controls the services before prescription drugs are transferred to the customer. CarelonRx determined it is the principal due to its contractual rights to design and develop a listing of prescription drugs offered to the customer (formulary management); its control over establishing the pharmacy network available to the customer to have its prescription fulfilled (network management); and its discretion over establishing the pricing for prescription drugs. Overall, control over these activities indicate CarelonRx is primarily responsible for fulfilling the promise to provide PBM services. Product revenue includes ingredient costs (net of any rebates or discounts), including any co-payments made by or on behalf of the customer, and administrative fees. CarelonRx recognizes revenue when control of the prescription drugs is transferred to customers, in an amount it expects to be entitled to in exchange for the products or services provided.

For our non-risk-based contracts, we had no material contract assets, contract liabilities or deferred contract costs recorded on our consolidated balance sheet at December 31, 2022. Revenue recognized in 2022 and 2021 from performance obligations related to prior years, such as due to changes in transaction price, was not material. For contracts that have an original expected duration of greater than one year, revenue expected to be recognized in future periods related to unfulfilled contractual performance obligations and contracts with variable consideration related to undelivered performance obligations is not material.

Share-Based Compensation: Our current compensation philosophy provides for share-based compensation, including stock options, restricted stock awards and an employee stock purchase plan. Stock options are granted for a fixed number of shares with an exercise price at least equal to the fair value of the shares at the date of the grant. Restricted stock awards are issued at the fair value of the stock on the grant date. The employee stock purchase plan allows for a purchase price per share which is 90% of the fair value of a share of common stock on the lower of the first or last trading day of the plan quarter. The employee stock purchase plan discount is recognized as compensation expense based on GAAP guidance. All other share-based payments to employees are recognized as compensation expense in our consolidated statements of income based on their fair values. Additionally, excess tax benefits, which result from actual tax benefits realized when awards vest or options are exercised exceeding deferred tax benefits previously recognized based on grant date fair value, are recognized as tax benefits in the consolidated statements of income.

agents, brokers and retail partnerships for Individual and Medicare customers, and for certain Group risk-based customers with a smaller employee base. Products for Group risk-based customers with a larger employee base are generally sold through independent brokers or consultants retained by the customer who work with industry specialists from our in-house sales force. In the Individual and Group markets, we offer products through state or federally facilitated marketplaces, or Public Exchanges, and off-exchange products. The cost of advertising and marketing for product promotion is expensed as incurred, while advertising and marketing costs associated with our corporate image are expensed when first aired. Total advertising and marketing expense was $511, $588 and $558 for the years ended December 31, 2022, 2021 and 2020, respectively.

Health Insurance Provider Fee: The ACA imposed an annual Health Insurance Provider Fee (“HIP Fee”) on health insurers that wrote certain types of health insurance on U.S. risks, which was permanently repealed effective January 1, 2021. The HIP Fee was non-deductible for federal income tax purposes. Our affected products were priced to cover the increased selling, general and administrative and income tax expenses associated with the HIP Fee when it was in effect. The HIP Fee was $15,523 for 2020 and was permanently eliminated beginning in 2021. For the year ended December 31, 2020, we recognized $1,570 as selling, general and administrative expense related to the HIP Fee.

Leases: We lease office space and certain computer and related equipment under noncancelable operating leases. We determine whether an arrangement is or contains a lease at its inception. We recognize lease liabilities based on the present value of the minimum lease payments not yet paid by using the lease term, any amounts probable of being owed under any residual value guarantees and the discount rate determined at lease commencement. As our leases do not generally provide an implicit rate, we use our incremental secured borrowing rate commensurate with the underlying lease terms to determine the present value of our lease payments. Our lease liabilities may include amounts for options to extend or terminate a lease when it is reasonably certain that we will exercise that option. We recognize operating right-of-use (“ROU”) assets at an amount equal to the lease liability adjusted for prepaid or accrued rent, the remaining balance of any lease incentives and unamortized initial direct costs.

The operating lease liabilities are reported in other current liabilities and other noncurrent liabilities and the related ROU assets are reported in other noncurrent assets on our consolidated balance sheets. Lease expense for our operating leases is calculated on a straight-line basis over the lease term and is reported in selling, general and administrative expense on our consolidated statements of income. For our office space leases, we account for the lease and non-lease components (such as common area maintenance) as a single lease component. We also do not recognize a lease liability or ROU asset for our office space leases whose lease terms, at commencement, are twelve months or less and that do not include a purchase option or option to extend that we are reasonably certain to exercise.

We assess our ROU assets for impairment when there are indicators of impairment and compare the carrying amount of the ROU asset to its estimated undiscounted future cash flows. If the estimated undiscounted future cash flows are less than the carrying amount of the ROU asset, an impairment calculation is performed. An impairment loss is recorded for the difference of the ROU asset’s carrying value that exceeds its estimated discounted cash flows. During the years ended December 31, 2022, 2021 and 2020, we recorded $34, $136 and $258, respectively, for impairment and abandonment of ROU assets. See Note 18, “Leases” for additional information about the ROU asset impairment and abandonment charges.

Basic earnings per share excludes dilution and is computed by dividing income available to common shareholders by the weighted-average number of common shares outstanding for the period. Diluted earnings per share may include the dilutive effect of stock options, restricted stock and convertible debentures, using the treasury stock method. The treasury stock method assumes exercise of stock options and vesting of restricted stock, with the assumed proceeds used to purchase common stock at the average market price for the period. The difference between the number of shares assumed issued and the number of shares assumed purchased represents the dilutive shares.

Recently Adopted Accounting Guidance: In January 2021, the FASB issued Accounting Standards Update No. 2021-01, Reference Rate Reform (Topic 848) (“ASU 2021-01”). The amendments in ASU 2021-01 provide optional expedients and exceptions for applying GAAP to contract modifications and hedging relationships, subject to meeting certain criteria, that reference the London Interbank Offered Rate (“LIBOR”) or another reference rate expected to be discontinued because of the

In October 2020, the FASB issued Accounting Standards Update No. 2020-08, Codification Improvements to Subtopic 310-20, Receivables—Nonrefundable Fees and Other Costs (“ASU 2020-08”). The amendments in ASU 2020-08 clarify when an entity should assess whether a callable debt security is within the scope of accounting guidance, which impacts the amortization period for nonrefundable fees and other costs. ASU 2020-08 became effective for interim and annual reporting periods beginning after December 15, 2020. The amendments were applied on a prospective basis as of the beginning of the period of adoption for existing or newly purchased callable debt securities. We adopted ASU 2020-08 on January 1, 2021, and the adoption did not have an impact on our consolidated financial position, results of operations or cash flows.

In August 2020, the FASB issued Accounting Standards Update No. 2020-06, Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging—Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity (“ASU 2020-06”). The amendments eliminate two of the three accounting models that require separate accounting for convertible features of debt securities, simplify the contract settlement assessment for equity classification, require the use of the if-converted method for all convertible instruments in the diluted earnings per share calculation and expand disclosure requirements. The amendments became effective for our annual and interim reporting periods beginning after December 15, 2021. We adopted ASU 2020-06 on January 1, 2022 using the modified retrospective transition method, which resulted in an increase to our reported debt outstanding of $31, a decrease to our deferred tax liabilities of $8, and a corresponding cumulative-effect reduction to our opening retained earnings of $23, eliminating the bifurcation of the embedded conversion option; these amounts were not material to our overall consolidated financial position. The adoption of ASU 2020-06 did not have an impact on our results of operations or our consolidated cash flows. Use of the if-converted method did not have an impact on our overall earnings per share calculation.

In December 2019, the FASB issued Accounting Standards Update No. 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes (“ASU 2019-12”). The amendments in ASU 2019-12 remove certain exceptions to the general principles in Accounting Standards Codification Topic 740. The amendments also clarify and amend existing guidance to improve consistent application. The amendments became effective for our annual reporting periods beginning after December 15, 2020. The transition method (retrospective, modified retrospective, or prospective basis) related to the amendments depends on the applicable guidance, and all amendments for which there is no transition guidance specified are to be applied on a prospective basis. We adopted ASU 2019-12 on January 1, 2021, and the adoption did not have an impact on our consolidated financial position, results of operations or cash flows.

Recent Accounting Guidance Not Yet Adopted: 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 extended the original effective date by one year, with the amendments required for our interim and annual reporting periods beginning after December 15, 2022. This standard requires the Company to review cash flow assumptions for its long-duration insurance contracts at least annually and recognize the effect of changes in future cash flow assumptions in net income. This standard also requires the Company to update discount rate assumptions quarterly and recognize the effect of changes in these assumptions in other comprehensive income. The rate used to discount the Company’s reserves for future policy benefits will be based on an estimate of the yield for an upper-medium grade fixed-income instrument with a duration profile matching that of the Company’s liabilities. In addition, this standard changes the amortization method for deferred acquisition costs. The Company adopted the new standard on January 1, 2023, using the modified retrospective transition method for changes to the liability for future policy benefits and deferred acquisition costs as of the earliest period presented, January 1, 2021. The adoption did not have a material impact on our consolidated financial position, results of operations, cash flows, or related disclosures.
