SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES | SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Description of Business Aflac Incorporated (the Parent Company) and its subsidiaries (collectively, the Company) primarily sell supplemental health and life insurance in Japan and the United States (U.S.). The Company's insurance business is marketed and administered through Aflac Life Insurance Japan Ltd. (ALIJ) in Japan and through American Family Life Assurance Company of Columbus (Aflac), American Family Life Assurance Company of New York (Aflac New York), Continental American Insurance Company (CAIC), Tier One Insurance Company (TOIC) and Aflac Benefit Solutions, Inc. (ABS) in the U.S. The Company’s operations consist of two reportable business segments: Aflac Japan, which includes ALIJ, and Aflac U.S., which includes Aflac, Aflac New York, CAIC, TOIC and ABS. Aflac New York is a wholly owned subsidiary of Aflac. Most of Aflac's policies are individually underwritten and marketed through independent agents. With the exception of dental and vision products administered by ABS, and certain group life insurance products, Aflac U.S. markets and administers group products through CAIC, branded as Aflac Group Insurance. Additionally, Aflac U.S. markets its consumer markets products through TOIC. The Company's insurance operations in the U.S. and Japan service the two markets for the Company's insurance business. The Parent Company, other operating business units that are not individually reportable, and business activities, including reinsurance activities, not included in Aflac Japan or Aflac U.S. are included in Corporate and other. In 2022, the Company established Aflac Re Bermuda Ltd. (Aflac Re), a Bermuda domiciled insurer that reinsures certain policies issued by ALIJ. Aflac Re is subject to regulation in Bermuda, where the Bermuda Monetary Authority (BMA) has broad administrative powers relating to granting and revoking licenses to transact reinsurance business, approval of specific reinsurance transactions, capital requirements and solvency standards, limitations on dividends to shareholders, the nature of and limitations on investments, and the filing of financial statements in accordance with prescribed or permitted accounting practices. Financial results from Aflac Re are included in Corporate and other. Basis of Presentation The Company prepares its financial statements in accordance with U.S. generally accepted accounting principles (U.S. GAAP). These principles are established primarily by the Financial Accounting Standards Board (FASB). In these Notes to the Consolidated Financial Statements, references to U.S. GAAP issued by the FASB are derived from the FASB Accounting Standards Codification TM (ASC). The preparation of financial statements in conformity with U.S. GAAP requires the Company to make estimates based on currently available information when recording transactions resulting from business operations. The most significant items on the Company's balance sheet that involve a greater degree of accounting estimates and actuarial determinations subject to changes in the future are the valuation of investments and derivatives, deferred policy acquisition costs (DAC), liabilities for future policy benefits and income taxes. These accounting estimates and actuarial determinations are sensitive to market conditions, investment yields, interest rates, mortality, morbidity, commission and other acquisition expenses and terminations by policyholders. As additional information becomes available, or actual amounts are determinable, the recorded estimates are revised and reflected in the consolidated financial statements. Although some variability is inherent in these estimates, the Company believes the amounts provided are reasonable and reflective of the best estimates of management. The consolidated financial statements include the accounts of the Parent Company, its subsidiaries, and those entities required to be consolidated under applicable accounting standards. All material intercompany accounts and transactions have been eliminated. Significant Accounting Policies Foreign Currency Translation:The functional currency of Aflac Japan is the Japanese yen. The Company translates its yen-denominated financial statement accounts into U.S. dollars as follows. Assets and liabilities are translated at end-of-period exchange rates. Realized gains and losses on security transactions are translated at the exchange rate on the trade date of each transaction. Other revenues, expenses, and cash flows are translated using average exchange rates for the period. The resulting currency translation adjustments are reported in accumulated other comprehensive income. The Company includes in earnings the realized currency exchange gains and losses resulting from foreign currency transactions. The Parent Company has designated a majority of its yen-denominated liabilities (notes payable and yen-denominated loans) as non-derivative hedges and foreign currency forwards and options as derivative hedges of the foreign currency exposure of the Company's net investment in Aflac Japan. Outstanding principal and related accrued interest on these Parent Company liabilities and the fair value of these derivatives are translated into U.S. dollars at end-of-period exchange rates. Currency translation adjustments and changes in the fair value of these derivatives are recorded as unrealized foreign currency translation gains (losses) in other comprehensive income and are included in accumulated other comprehensive income. Insurance Revenue and Expense Recognition:Substantially all of the supplemental health and life insurance policies the Company issues are classified as long-duration contracts. The contract provisions generally cannot be changed or canceled during the contract period; however, the Company may adjust premiums for supplemental health policies issued in the U.S. within prescribed guidelines and with the approval of state insurance regulatory authorities. Insurance premiums for most of the Company's health and life policies, including cancer, accident, hospital, critical illness, supplemental dental and vision, term life, whole life, long-term care and disability, are recognized as earned premiums over the premium-paying periods of the contracts when due from policyholders. When earned premiums are reported, the related amounts of benefits and expenses are charged against such revenues. This association is accomplished by means of annual increases or decreases to the liability for future policy benefits (LFPB) and the deferral and subsequent amortization of policy acquisition costs. Premiums from the Company's products with limited-pay features, including cancer, medical and nursing care, term life, whole life, WAYS, and child endowment, are collected over a significantly shorter period than the contract term (i.e., the period during which benefits are provided). Premiums for these products are recognized as earned premiums over the premium-paying periods when due from policyholders. Any gross premium in excess of the net premium is deferred and recorded as a deferred profit liability, which is subsequently amortized in net earned premiums such that profits are recognized in a constant relationship with insurance in force. Net premium is calculated as gross premium multiplied by the net premium ratio (NPR) and represents the portion of gross premium required to provide for benefits and expenses. Benefits are recorded as an expense when they are incurred. An LFPB is recorded when premiums are recognized using the net premium method. Policyholders also have an option to pay discounted advanced premiums for certain of the Company's products. Advanced premiums are deferred and recognized when due from policyholders over the otherwise required contractual premium payment period. Benefit expense is bifurcated between benefits and claims and reserve remeasurement (gains) losses. The NPR is used to measure benefit expense and is calculated as the ratio of the present value of actual and future expected benefits and expenses to the present value of actual and future expected gross premiums. A revised NPR is calculated as of the beginning of each reporting period using updated future cash flow expectations. Reserve remeasurement (gains) losses represent the difference between two reserve measures both calculated as of the beginning of the current reporting period using the same locked-in discount rates. One reserve measure uses the NPR as of the end of the prior reporting period, and the second uses the revised NPR. Benefits and claims represent the difference in the liability balance calculated as of the beginning of the current reporting period and the end of the current reporting period both using the revised NPR and the locked-in discount rates. The locked-in interest accretion rate utilized for accretion of interest expense on insurance reserves is the original discount rate used at contract issue date. Advertising expense is reported as incurred in insurance and other expenses in the consolidated statements of earnings. Cash and Cash Equivalents:Cash and cash equivalents include cash on hand, money market instruments, and other debt instruments with a maturity of 90 days or less when purchased. Investments:The Company's debt securities consist of fixed maturity securities, which are classified as either held-to-maturity or available-for-sale. Securities classified as held-to-maturity are securities that the Company has the ability and intent to hold to maturity or redemption and are carried at amortized cost. All other fixed maturity debt securities are classified as available-for-sale and are carried at fair value. If the fair value is higher than the amortized cost for debt securities, the excess is an unrealized gain, and if lower than cost, the difference is an unrealized loss. The net unrealized gains and losses on securities available-for-sale, less related deferred income taxes, are recorded through other comprehensive income and included in accumulated other comprehensive income. Amortized cost of debt securities is based on the Company's purchase price adjusted for accrual of discount, or amortization of premium, and recognition of impairment charges, if any. The amortized cost of debt securities the Company purchases at a discount or premium will equal the face or par value at maturity or the call date, if applicable. Interest is reported as income when earned and is adjusted for amortization of any premium or discount. The Company has investments in marketable equity securities which are carried at fair value. Changes in the fair value of equity securities are recorded in earnings as a component of net investment gains (losses). The Company has investments in variable interest entities (VIEs). Criteria for evaluating VIEs for consolidation focuses on identifying which enterprise has the power to direct the activities of a variable interest entity that most significantly impact the entity's economic performance and (1) the obligation to absorb losses of the entity or (2) the right to receive benefits from the entity. The Company is the primary beneficiary of certain VIEs, and therefore consolidates these entities in its financial statements. While the consolidated VIEs generally operate within a defined set of contractual terms, there are certain powers that are retained by the Company that are considered significant in the conclusion that the Company is the primary beneficiary. These powers vary by structure but generally include the initial selection of the underlying collateral; the ability to obtain the underlying collateral in the event of default; and, the ability to appoint or dismiss key parties in the structure. In particular, the Company's powers surrounding the underlying collateral were considered to be the most significant powers because these most significantly impact the economics of the VIE. The Company has no obligation to provide any continuing financial support to any of the entities in which it is the primary beneficiary. The Company's maximum loss is limited to its original investment. Neither the Company nor any of its creditors have the ability to obtain the underlying collateral, nor does the Company have control over the instruments held in the VIEs, unless there is an event of default. For those entities where the Company is the primary beneficiary, the consolidated entity's assets are segregated on the balance sheet by the caption "consolidated variable interest entities," and consist of fixed maturity securities, equity securities, loan receivables, limited partnerships and derivative instruments. For the mortgage- and asset-backed securities held in the Company's fixed maturity portfolio, the Company recognizes income using a constant effective yield, which is based on anticipated prepayments and the estimated economic life of the securities. When estimates of prepayments change, the effective yield is recalculated to reflect actual payments to date and anticipated future payments. The net investment in mortgage- and asset-backed securities is adjusted to the amount that would have existed had the new effective yield been applied at the time of acquisition. This adjustment is reflected in net investment income. The Company uses the specific identification method to determine the gain or loss from securities transactions and report the realized gain or loss in the consolidated statements of earnings as net investment gain or loss. Securities transactions are accounted for based on values as of the trade date of the transaction. The Company lends fixed maturity and public equity securities to financial institutions in short-term security-lending transactions. These securities continue to be carried as investment assets on the Company's balance sheet during the terms of the loans and are not reported as sales. The Company receives cash or other securities as collateral for such loans. For loans involving unrestricted cash or securities as collateral, the collateral is reported as an asset with a corresponding liability for the return of the collateral. For loans where the Company receives as collateral securities that the Company is not permitted to sell or repledge, the collateral is not reported as an asset. Commercial mortgage and other loans include transitional real estate loans (TREs), commercial mortgage loans (CMLs), middle market loans (MMLs), and other loans. The Company's investments in TREs, CMLs, MMLs, and other loans are accounted for as loan receivables and are recorded at amortized cost on the acquisition date. The Company has the intent and ability to hold these loan receivables for the foreseeable future or until they mature and therefore, they are considered held for investment and are carried at amortized cost in the commercial mortgage and other loans line in its consolidated balance sheets. The amortized cost of the loan receivables reflects allowances for expected lifetime credit losses estimated as of each reporting date. Income on commercial mortgage and other loans is recognized using the interest method. Other investments include policy loans, limited partnerships, real estate owned (REO), and short-term investments with maturities at the time of purchase of one year or less, but greater than 90 days. Limited partnerships are accounted for using the equity method of accounting. Under the equity method of accounting, the Company reports its proportionate share of the investee's earnings or losses as a component of net investment income in its consolidated statements of earnings. The underlying investments held by the Company’s limited partnerships primarily consist of private equity and real estate. REO consists of property held-and-used for the production of income and property held-for-sale. REO is obtained through foreclosure or deed in lieu of foreclosure of certain of the Company's loan receivables. When held for the production of income, REO is recorded at fair value upon acquisition, which establishes the property’s initial cost basis. Thereafter, it is carried at cost less accumulated depreciation and written down to fair value for impairment losses. Depreciation is recorded on a straight-line basis over the estimated useful life of the asset and is reported in net investment income. A review for impairment is performed whenever events or circumstances indicate that the carrying value may not be recoverable. An impairment loss is recognized in net investment gains (losses) when the carrying value of the property exceeds the expected undiscounted cash flows generated from the property, at which point the carrying value is written down to an estimated fair value. Real estate held-for-sale is initially recorded at fair value less costs to sell and is subsequently measured at the lower of its initial carrying amount or fair value less costs to sell. Properties held-for-sale are not depreciated. Net operating income earned on REO is reported as a component of net investment income. Short-term investments are stated at amortized cost, which approximates fair value. The Company designates nonaccrual status for a nonperforming loan or debt security or a loan or debt security that is not generating its stated interest rate because of nonpayment of periodic interest or principal by the borrower. The Company applies the cash basis method to record any payments received on nonaccrual assets. The Company resumes the accrual of interest on fixed maturity securities and loans that are currently making contractual payments or for those that are not current where the borrower has paid timely (less than 30 days outstanding). Credit Losses: The Company estimates expected lifetime credit losses on financial assets measured at amortized cost including short-term receivables, premiums receivable, held-to-maturity fixed maturity securities, loan receivables, loan commitments and reinsurance recoverables. For available-for-sale fixed maturity securities, the Company evaluates estimated credit losses only when the fair value of the available-for-sale fixed maturity security is below its amortized cost basis. Credit loss changes are recorded as a component of net investment gains (losses) for the Company’s held-to-maturity and available-for-sale securities, loan receivables, including collateral dependent assets, loan commitments and reinsurance recoverables, whereas credit losses on premium receivables are recorded in net earned premiums in the consolidated statement of earnings. The Company’s off-balance sheet credit exposure is primarily attributable to loan commitments that are not unconditionally cancellable. The Company considers the contractual period of exposure to credit risk, the likelihood that funding will occur, the risk of loss, and the current conditions and expectations of future economic conditions to develop the estimate of expected credit losses. The Company records the estimate of expected credit losses for certain loan commitments within other liabilities in the consolidated balance sheet. Write-offs and partial write-offs are recorded as a reduction to the amortized cost of the loan or fixed maturity security balance and a corresponding reduction to the credit allowance. The Company has elected not to measure an allowance on accrued interest income for all asset types, because the uncollectible accrued interest receivable is written off in a timely manner. The Company writes off accrued interest when it is more than ninety days past due by reducing interest income, which is a component of net investment income, in the consolidated statement of earnings. The Company records due premium receivable net of current expected credit losses in the receivables line item in the consolidated balance sheet, utilizing an aging methodology based on historical loss information, adjusted for current conditions and reasonable and supportable forecasts. Changes in the estimated credit losses related to premium receivable are recorded in net earned premiums in the consolidated statement of earnings. Derivatives and Hedging: Freestanding derivative instruments are reported in the consolidated balance sheet at fair value within other assets and other liabilities, with changes in value reported in earnings and/or other comprehensive income. These freestanding derivatives include foreign currency forwards, foreign currency options, foreign currency swaps, interest rate swaps and interest rate swaptions. The Company does not use derivatives for trading purposes. The Company may purchase certain investments or enter into contracts that contain embedded derivatives. The Company assesses whether an embedded derivative is clearly and closely related to its host contract. If the Company determines that the embedded derivative is not clearly and closely related to the host contract, and a separate instrument with the same terms would qualify as a derivative instrument, the embedded derivative is separated from that contract, held at fair value, and reported with the host instrument in the consolidated balance sheets, with changes in fair value reported in earnings. If the Company has elected the fair value option, the embedded derivative is not bifurcated, and the entire investment is held at fair value with changes in fair value reported in earnings. See Note 5 for a discussion on how the Company determines the fair value of its derivatives. Accruals on derivatives are typically recorded in other assets or other liabilities in the consolidated balance sheets. To qualify for hedge accounting treatment, a derivative must be highly effective in mitigating the designated risk attributable to the hedged item. At the inception of hedging relationships the Company formally documents all relationships between hedging instruments and hedged items, as well as its risk-management objectives and strategies for undertaking the respective hedging relationship, and the methodology that will be used to assess the effectiveness of the hedge relationship at and subsequent to hedge inception. The Company documents the designation of each hedge as either (i) a hedge of the variability of cash flows to be received or paid related to a recognized asset or liability or the hedge of a forecasted transaction ("cash flow hedge"); (ii) a hedge of the exposure to changes in the fair value of a recognized asset or liability, attributable to a particular risk ("fair value hedge"); or (iii) a hedge of foreign currency exposure of a net investment in a foreign operation ("net investment hedge"). The documentation process includes linking derivatives and non-derivative financial instruments that are designated in hedge relationships with specific assets or groups of assets or liabilities in the statement of financial position or to specific forecasted transactions and defining the effectiveness testing methods to be used. At the hedge inception and on an ongoing quarterly basis, the Company also formally assesses whether the derivatives and non-derivative financial instruments used in hedging activities have been, and are expected to continue to be, highly effective in offsetting their designated risk. The assessment of hedge effectiveness determines the accounting treatment of changes in fair value. Hedge effectiveness is assessed using qualitative and quantitative methods. Qualitative methods may include the comparison of critical terms of the derivative to the hedged item, and quantitative methods may include regression, dollar offset, or other statistical analysis of changes in fair value or cash flows associated with the hedge relationship. For derivative instruments that are designated in cash flow hedge relationships, the gain or loss on the portion of the hedging instrument included in the assessment of effectiveness is reported as a component of accumulated other comprehensive income (loss) and reclassified into earnings in the same period or periods during which the hedged transaction affects earnings. Amounts reclassified are recorded in the line item of the consolidated statements of earnings in which gain or loss on the hedged item is recorded. The Company includes all components of each derivative's gain or loss in the assessment of hedge effectiveness. For derivative instruments that are designated in fair value hedge relationships, the gain or loss on the hedged item and the portion of the hedging instrument included in the assessment of effectiveness are recorded in the line item of the consolidated statements of earnings in which gain or loss on the hedged item is recorded. When assessing the effectiveness of the Company's fair value hedges, the Company excludes the changes in fair value related to the difference between the spot and forward rates on its foreign currency forwards, the change in fair value of cross-currency swaps not resulting from fluctuations in spot currency rates, and the time value component of foreign exchange options and interest rate swaptions. For interest rate swaptions and cross-currency interest rate swaps designated in fair value hedges of interest rate risk, the excluded component is recognized in other comprehensive income (loss) and amortized into earnings (net investment income) over its legal term. For derivative and/or non-derivative hedging instruments designated in net investment hedge relationships with the Company’s investment in Aflac Japan, the Company makes its net investment hedge designation at the beginning of each quarter. When the hedging instrument is a foreign currency derivative, the Company assesses hedge effectiveness using the spot-rate method. According to that method, the change in fair value of the hedging instrument due to fluctuations in the spot exchange rate is recorded in the unrealized foreign currency component of other comprehensive income and reclassified to earnings only when the hedged net investment is sold, or when a liquidation of the respective net investment in the foreign entity is substantially completed. If and when a sale or liquidation occurs, the changes in fair value of the derivative deferred in the unrealized foreign currency component of other comprehensive income will be released in the same income statement line item where the gain (loss) on the hedged net investment would be recorded upon sale. All other changes in fair value of the hedging instrument are considered the “excluded component” and are accounted for in net investment gains (losses). Should these designated net investment hedge positions exceed the Company's net investment in Aflac Japan, the foreign exchange effect on the portion that exceeds its investment in Aflac Japan would be recognized in current earnings within net investment gains (losses). The Company discontinues hedge accounting prospectively when (1) it is determined that the derivative is no longer highly effective in offsetting changes in the estimated cash flows or fair value of a hedged item; (2) the derivative is de-designated as a hedging instrument; or (3) the derivative expires or is sold, terminated or exercised. When hedge accounting is discontinued on a cash flow hedge or fair value hedge, the derivative is carried in the consolidated balance sheets at its estimated fair value, with changes in estimated fair value recognized in current period earnings. For discontinued cash flow hedges, including those where the derivative is sold, terminated or exercised, amounts previously deferred in other comprehensive income (loss) are reclassified into earnings when earnings are impacted by the cash flow of the hedged item. If a derivative is not designated as an accounting hedge or its use in managing risk does not qualify for hedge accounting, changes in the estimated fair value of the derivative are generally reported within other gains (losses), which is a component of net investment gains (losses). The fluctuations in estimated fair value of derivatives that have not been designated for hedge accounting can result in volatility in net earnings. The Company receives and pledges cash or other securities as collateral on open derivative positions. Cash received as collateral is reported as an asset with a corresponding liability for the return of the collateral. Cash pledged as collateral is recorded as a reduction to cash, and a corresponding receivable is recognized for the return of the cash collateral. The Company generally can repledge or resell collateral obtained from counterparties, although the Company does not typically exercise such rights. Securities received as collateral are not recognized unless the Company was to exercise its right to sell that collateral or exercise remedies on that collateral upon a counterparty default. Securities that the Company has pledged as collateral continue to be carried as investment assets on its balance sheet. The Company does not offset amounts recognized for derivative instruments and amounts recognized for the right to reclaim or the obligation to return cash collateral arising from derivative instruments executed with the same counterparty under a master netting arrangement. For additional information on the Company's derivative instruments, see Note 4. Deferred Policy Acquisition Costs: Certain direct and incremental costs of acquiring insurance contracts are deferred and amortized on a grouped-contract basis over the expected term of the related contracts, using a constant-level basis. For life and health products issued in Japan, the constant-level basis used is units in force, which is a proxy for face amount, and insurance in force, respectively. For life and health products issued in the U.S., the constant-level basis used is face amount and number of policies in force, respectively. Amortization is computed using the same contract groupings (also referred to as cohorts) and mortality and termination assumptions that are used in computing the LFPB, and these assumptions are reviewed and updated at least annually. The effects of changes in assumptions are recognized prospectively over the remaining contract term as a revision of the future amortization pattern, while current period amortization is calculated based on the actual experience during the quarter. Deferred costs include the excess of current-year commissions over ultimate renewal-year commissions and certain incremental direct policy issue, underwriting and sales expenses directly related to successful policy acquisition. For some products, policyholders can elect to modify product benefits, features, rights or coverages by exchanging a contract for a new contract or by amendment, endorsement, or rider to a contract, or by the election of a feature or coverage within a contract. These transactions are known as internal replacements. The Company performs a two-stage analysis of the internal replacements to determine if the modification is substantive to the base policy. The stages of evaluation are as follows: 1) determine if the modification is integrated with the base policy, and 2) if it is integrated, determine if the resulting contract is substantially changed. For internal replacement transactions where the resulting contract is substantially unchanged, unamortized deferred acquisition costs from the original policy continue to be amortized over the expected life of the cohort, and the costs of replacing the policy are accounted for as policy maintenance costs and expensed as incurred. For an internal replacement transaction that results in a policy that is substantially changed, the policy is treated as lapsed for amortization purposes, and the costs of acquiring the new policy are capitalized and amortized in accordance with the Company's accounting policies for deferred acquisition costs. Riders can be considered internal replacements that are either integrated or non-integrated resulting in either substantially changed or substantially unchanged treatment. Riders are evaluated based on the specific facts and circumstances of the rider and are considered an expansion of the existing benefits with additional premium required. Non-integrated riders to existing contracts do not change the Company's profit expectations for the related products and are treated as a new policy establishment for incremental coverage. Goodwill: Goodwill is an asset representing the future economic benefits arising from other assets acquired in a business combination that are not individually identified and separately recognized. The amount of goodwill recognized is also impacted by measurement differences resulting from certain assets and liabilities not recorded at fair value (e.g. income taxes, employee benefits). Goodwill is not amortized, but is tested for impairment at a level of a reporting unit at least annually, in the same reporting period each year. Goodwill is included in the other assets line item in the consolidated balance sheets and was $265 million at both December 31, 2023 and December 31, 2022. A significant majority of the goodwill balance is attributable to the following business combinations within the Aflac U.S. segment, which represents the reporting unit for goodwill impairment testing: (i) CAIC acquisition in 2009, (ii) Empoweredbenefits, LLC acquisition in 2015, (iii) ABS acquisition in 2019, and (iv) acquisition of Zurich's business in 2020. Policy Liabilities:For long-duration insurance contracts, the Company calculates an integrated reserve that represents all payments under the contract including future expected claims and unpaid policy claims and related expenses. The LFPB is measured using the net level premium method. Long-duration insurance contracts issued by the Company are grouped into annual calendar-year cohorts based on the contract issue date, reportable segment, legal entity and product type. Limited-pay contracts are grouped into separate cohorts from other traditional products in the same manner and are further separated based on their premium payment structures. The LFPB is determined as the present value of expected future policy benefits to be paid to or on the behalf of policyholders and certain related expenses less the present value of expected future net premiums receivable under the Company’s insurance contracts, where expected future net premiums receivable are future gross premiums receivable under the contract multiplied by the NPR. Future policy benefits are calculated using assumptions and estimates including mortality, morbidity, termination (also referred to as lapses), expense and discount rates. The assumptions and estimates that the Company uses depend on its judgment regarding the likelihood of future events and are inherently uncertain. Cash flow assumptions (mortality, morbidity, and termination) are established at policy inception and are evaluated each quarter to determine if an update is needed. To facilitate a more detailed review of cash flow assumptions, experience studies are performed annually during the third quarter. Changes in cash flow assumptions are the result of applying the updated best estimate assumptions as of the beginning of the reporting period and are recognized in reserve remeasurement (gains) losses in the consolidated statements of earnings. Expense assumptions are established at policy inception and determined for each issue-year cohort as a percentage of paid claims. These expense assumptions are locked in and remain unchanged over the term of the insurance policy. Actual experience is reflected in the calculation of future policy benefits each quarter, and changes in the liability due to actual experience are recognized in reserve remeasurement (gains) losses in the consolidated statements of earnings. Discount rates used to calculate net premiums are locked in at policy inception and represent the basis to recognize interest expense in the consolidated statements of earnings. Discount rates used to measure the carrying value of the LFPB in the consolidated balance sheets are updated each reporting period, and the difference between the liability balances calculated using the locked-in discount rates and the updated discount rates is recognized in accumulated other comprehensive income (loss) (AOCI). The Company has designed its discount rate methodology for the U.S. and Japan insurance business. The methodology incorporates constructing a current discount rate curve separately for discounting cash flows used to calculate the U.S. and Japan LFPBs, reflective of the characteristics of the insurance liabilities, such as currency and tenor. Discount rates comprising each curve are determined by reference to upper-medium grade (low credit risk) fixed-income instrument yields that reflect the duration characteristics of the corresponding insurance liabilities. The Company uses for these yields single-A rated fixed income instruments with credit ratings based on international rating standards. Where only local ratings are available, the Company selects the fixed-income instruments with local ratings that are equivalent to a single-A rating based on international rating standards. The methodology is designed to prioritize observable inputs based on market data available in the local debt markets where the respective policies were issued in the currency in which the policies are denominated. For the discount rates applicable to tenors for which the single-A debt market is not liquid or there is little or no observable market data, the Company uses various estimation techniques consistent with the fair value guidance in ASC 820 - Fair Value Measurement, which include, but are not limited to: (i) for tenors where there is less observable market data and/or the observable market data is available for similar instruments, estimating tenor-specific single-A credit spreads and applying them to risk-free government rates; (ii) for tenors where there is very limited or no observable single-A or similar market data, interpolation and extrapolation techniques. The locked-in discount rate used for the computation of interest accretion on LFPBs is determined separately for each issue-year cohort as a single discount rate, calculated as the weighted-average of monthly upper-medium grade (low credit risk) fixed-income instrument forward curves in the calendar year, determined using the methodology described above and weighted using issued annualized premiums for each issue month. The single discount rate for each issue-year cohort is determined by solving for a rate that produces an equivalent net premium ratio to the forward curve and will remain unchanged after the calendar year of issue. Unearned premiums consist primarily of discounted advance premiums on deposit from policyholders in conjunction with their purchase of certain Aflac Japan limited-pay insurance products. These advanced premiums are deferred upon collection and recognized as earned premiums over the contractual premium payment period. The other policyholders’ funds liability consists primarily of the fixed annuity line of business in Aflac Japan which has fixed benefits and premiums. For internal replacements that are determined to be substantially changed, policy liabilities related to the original policy that was replaced are immediately released, and policy liabilities are established for the new insurance contract. The policy reserves are evaluated based on the new policy features, and changes are recognized at the date of contract change/modification. For internal replacements that are substantially unchanged, no changes to the reserves are recognized. For modifications that are not integrated with the base policy, new coverage is recognized as a separately issued contract within the current cohort. Reinsurance: The Company enters into reinsurance agreements in the normal course of business. For each reinsurance agreement, the Company determines if the agreement provides indemnification against loss or liability relating to insurance risk in accordance with applicable accounting standards. Reinsurance premiums and benefits paid or provided are accounted for on bases consistent with those used in accounting for the original policies issued and the terms of the reinsurance contracts. Premiums, benefits and acquisition costs are reported net of insurance ceded. Income Taxes: Income tax provisions are generally based on pretax earnings reported for financial statement purposes, which differ from those amounts used in preparing the Company's income tax returns. Deferred income taxes are recognized for temporary differences between the financial reporting basis and income tax basis of assets and liabilities, based on enacted tax laws and statutory tax rates applicable to the periods in which the Company expects the temporary differences to reverse. The Company records deferred tax assets for tax positions taken based on its assessment of whether the tax position is more likely than not to be sustained upon examination by taxing authorities. A valuation allowance is established for deferred tax assets when it is more likely than not that an amount will not be realized. Policyholder Protection Corporation and State Guaranty Association Assessments: In Japan, the government has required the insurance industry to contribute to a policyholder protection corporation. The Company recognizes a charge for its estimated share of the industry's obligation once it is determinable. The Company reviews the estimated liability for policyholder protection corporation contributions on an annual basis and reports any adjustments in Aflac Japan's expenses. In the U.S., each state has a guaranty association that supports insolvent insurers operating in those states. The Company's policy is to accrue assessments when the entity for which the insolvency relates has met its state of domicile's statutory definition of insolvency, the amount of the loss is reasonably estimable and the related premium upon which the assessment is based is written. See Note 15 for further discussion of the guaranty fund assessments charged to the Company. Treasury Stock: Treasury stock is reflected as a reduction of shareholders' equity at cost. The Company uses the weighted-average purchase cost to determine the cost of treasury stock that is reissued. The Company includes any gains and losses in additional paid-in capital when treasury stock is reissued. Share-Based Compensation: The Company measures compensation cost related to its share-based payment transactions at fair value on the grant date, and the Company recognizes those costs in the financial statements over the vesting period during which the employee provides service in exchange for the award. The Company has made an entity-wide accounting policy election to estimate the number of awards that are expected to vest and the corresponding forfeitures. Earnings Per Share: The Company computes basic earnings per share (EPS) by dividing net earnings by the weighted-average number of unrestricted shares outstanding for the period. Diluted EPS is computed by dividing net earnings by the weighted-average number of shares outstanding for the period plus the shares representing the dilutive effect of share-based awards. Reclassifications: Certain reclassifications have been made to prior-year amounts to conform to current-year reporting classifications. These reclassifications had no impact on net earnings or total shareholders' equity. New Accounting Pronouncements Recently Adopted Accounting Pronouncements Accounting Standards Update (ASU) 2023-02 Investments - Equity Method and Joint Ventures (Topic 323): Accounting for Investments in Tax Credit Structures Using the Proportional Amortization Method In March 2023, the FASB issued amendments to permit reporting entities to elect to account for their tax equity investments, regardless of the tax credit program from which the income tax credits are received, using the proportional amortization method if certain conditions are met. Under the proportional amortization method, an entity amortizes the initial cost of the investment in proportion to the income tax credits and other income tax benefits received and recognizes the net amortization and income tax credits and other income tax benefits in the income statement as a component of income tax expense (benefit). The Company early adopted this guidance on July 1, 2023. The adoption of this guidance did not have a significant impact on the Company's financial position, results of operations or disclosures. ASU 2022-02, Financial Instruments - Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures In March 2022, the FASB issued amendments that eliminated the accounting guidance for troubled debt restructurings (TDRs) for creditors, required enhanced disclosures for creditors about loan modifications when a borrower is experiencing financial difficulty, and required public business entities to include current-period gross write-offs in the vintage disclosure tables. As a result of eliminating the TDR guidance for creditors, all loan modifications will follow the existing loan refinancing or restructuring guidance. The Company adopted this guidance on January 1, 2023 on a prospective basis. The adoption did not have an impact on the Company’s financial position or results of operations. ASU 2018-12 Financial Services - Insurance: Targeted Improvements to the Accounting for Long-Duration Contracts, as clarified and amended by: ASU 2019-09 Financial Services - Insurance: Effective Date ASU 2020-11 Financial Services - Insurance: Effective Date and Early Application In August 2018, the FASB issued amendments that significantly changed how insurers account for long-duration contracts. The Company adopted the standard on January 1, 2023 using a modified retrospective transition method which resulted in applying the amended guidance as of the beginning of the earliest period presented on the January 1, 2021 transition date (Transition Date). The modified retrospective transition method generally results in applying the guidance to contracts on the basis of existing carrying values as of the Transition Date. On the Transition Date, the Company calculated the ratio of the present value of expected future policy benefits and expenses less existing carrying values to the present value of expected future gross premiums (Transition Date NPR) using updated assumptions and the discount rate immediately before the Transition Date. The Company capped the Transition Date NPR at 100% for any cohorts with a Transition Date NPR greater than 100%. The Company calculated the LFPB using the Transition Date NPR (capped at 100% if required) and two different discount rates: (i) the discount rate used immediately before the Transition Date, and (ii) the discount rate determined by reference to the Transition Date market level yields for upper-medium grade (low credit risk) fixed income instruments (as of December 31, 2020). For cohorts with their Transition Date NPR capped at 100%, the Company recorded as an adjustment (decrease) to opening retained earnings any difference between the LFPB calculated using the discount rate immediately before the Transition Date and the existing carrying value as of the Transition Date. For all cohorts on the Transition Date, the Company recorded in AOCI net of tax, the difference in the LFPB calculated using the two different discount rates (i.e., the discount rate used immediately before the Transition Date and the updated discount rate as of the Transition Date). Upon adoption, the Company adjusted opening equity for the Transition Date impacts to AOCI and retained earnings and adjusted prior periods presented (years 2021 and 2022) following the updated standard. Based upon the modified retrospective transition method, the Transition Date impact from adoption resulted in a decrease in AOCI of approximately $18.6 billion and a decrease in retained earnings (RE) of approximately $0.3 billion. All relevant prior-year amounts have been adjusted for the adoption of ASU 2018-12. See Note 6 and Note 7 for expanded disclosures for DAC and future policy benefits, respectively, required as a result of the amended guidance. Transition Impact to Shareholder's Equity The following table presents the cumulative transition impact as of January 1, 2021 to the Company’s shareholders' equity as a result of the adoption of ASU 2018-12, using the modified retrospective transition method.

(1) Impact to retained earnings is driven primarily by capping the Transition Date NPR on Care products. Transition Impact on the Liability for Future Policy Benefits The Company adopted ASU 2018-12 using the modified retrospective transition method. The tables below present the disaggregated transition impacts to the Company’s LFPB as a result of adoption, split between the changes in the present value of expected future net premiums and the present value of expected future policy benefits as of the Transition Date and the LFPB rollforward for the year ended December 31, 2021. The locked-in discount rates on the policies held at the Transition Date reflect the locked-in rates in existence immediately before the Transition Date. See Note 7 for additional information. Under the modified retrospective transition method, the NPR for future policy benefits existing as of the Transition Date considers the carryover basis of those liabilities, which equals the future policy benefits and unpaid policy claims balance as of December 31, 2020. If the revised Transition Date NPR for a cohort is greater than 100%, the Company capped the Transition Date NPR at 100% and increased the LFPB with an offsetting decrease to opening retained earnings. The LFPB recorded in the consolidated balance sheets includes the deferred profit liability for limited-payment contracts. This deferred profit liability is not included in the Transition Date and LFPB rollforwards. For products with limited-payment features, to the extent the transition date adjustment related to updating cash flow assumptions is favorable, the Company increased the deferred profit liability. The following table presents the transition impacts to the present value of expected future net premiums, gross of internal and external ceded reinsurance, by reporting segment and disaggregated by product type due to the cumulative effect of the change in accounting principle as a result of the adoption of ASU 2018-12 using the modified retrospective transition method.

The adoption of ASU 2018-12 did not have an impact on the Company's balance for deferred policy acquisition costs upon adoption. In conjunction with the adoption of ASU 2018-12, the Company changed its practice of recording the change in the deferred profit liability on products with limited-payment features from the benefits and claims, net line item to the net earned premiums line item in the consolidated statements of earnings. This reclassification had no impact on net earnings. The change in presentation has been made for all comparative periods presented. Accounting Pronouncements Pending Adoption ASU 2023-09 Income Taxes (Topic 740) – Improvements to Income Tax Disclosures In December 2023, the FASB issued amendments that require enhanced income tax disclosures including (1) disclosure of specific categories and greater disaggregation of information in the rate reconciliation and (2) income taxes paid disaggregated by jurisdiction. It also includes certain other amendments to improve the effectiveness of income tax disclosures. The amendments are effective for annual periods beginning after December 15, 2024. Early adoption is permitted. The adoption of this guidance is not expected to have a significant impact on the Company’s financial position or results of operations. The Company is evaluating the impact of adoption on its disclosures. ASU 2023-07 Segment Reporting (Topic 280) – Improvements to Reportable Segment Disclosures In November 2023, the FASB issued amendments that will add certain segment disclosures related to significant segment expenses and require that a public entity disclose the title and position of the Chief Operating Decision Maker (CODM) and an explanation of how the CODM uses the reported measure(s) of segment profit or loss in assessing segment performance and deciding how to allocate resources. The amendments are effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. Early adoption is permitted. The Company is evaluating the impact of adoption on its financial position, results of operations and disclosures. Recent accounting guidance not discussed above is not applicable, did not have, or is not expected to have a material impact to the Company's business.
