SUMMARY OF SIGNIFICANT ACCOUNTI

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	9 Months Ended

Organization, Consolidation and Presentation of Financial Statements [Abstract]
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Description of Business Aflac Incorporated (the Parent Company) and its subsidiaries (collectively, the Company) primarily sell supplemental health and life insurance in the United States (U.S.) and Japan. The Company's insurance business is marketed and administered through American Family Life Assurance Company of Columbus (Aflac) in the U.S. and through Aflac Life Insurance Japan Ltd. (ALIJ) in Japan. The Company’s operations consist of two reportable business segments: Aflac U.S., which includes Aflac, and Aflac Japan, which includes ALIJ. American Family Life Assurance Company of New York (Aflac New York) is a wholly owned subsidiary of Aflac. Most of Aflac's policies are individually underwritten and marketed through independent agents. With the exception of dental and vision products administered by Aflac Benefits Solutions, Inc. (ABS), formerly known as Argus Dental & Vision, Inc., and certain group life insurance products, Aflac U.S. markets and administers group products through Continental American Insurance Company (CAIC), branded as Aflac Group Insurance. The Company's insurance operations in the U.S. and Japan service the two markets for the Company's insurance business. Aflac Japan's revenues, including net gains and losses on its investment portfolio, accounted for 72% and 69% of the Company's total revenues in the nine-month periods ended September 30, 2022 and 2021, respectively. The percentage of the Company's total assets attributable to Aflac Japan was 79% at September 30, 2022, compared with 82% at December 31, 2021. Basis of Presentation The Company prepares its financial statements in accordance with U.S. generally accepted accounting principles (U.S. GAAP). These principles are established primarily by the Financial Accounting Standards Board (FASB). In these Notes to the Consolidated Financial Statements, references to U.S. GAAP issued by the FASB are derived from the FASB Accounting Standards Codification TM (ASC). The preparation of financial statements in conformity with U.S. GAAP requires the Company to make estimates based on currently available information when recording transactions resulting from business operations. The most significant items on the Company's balance sheet that involve a greater degree of accounting estimates and actuarial determinations subject to changes in the future are the valuation of investments and derivatives, deferred policy acquisition costs (DAC), liabilities for future policy benefits and unpaid policy claims, and income taxes. These accounting estimates and actuarial determinations are sensitive to market conditions, investment yields, mortality, morbidity, commission and other acquisition expenses, and terminations by policyholders. As additional information becomes available, or actual amounts are determinable, the recorded estimates are revised and reflected in operating results. Although some variability is inherent in these estimates, the Company believes the amounts provided are reasonable and reflective of the best estimates of management. The unaudited 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. In the opinion of management, the accompanying unaudited consolidated financial statements of the Company contain all adjustments, consisting of normal recurring accruals, which are necessary to fairly present the consolidated balance sheets as of September 30, 2022 and December 31, 2021, the consolidated statements of earnings and comprehensive income (loss) for the three- and nine-month periods ended September 30, 2022 and 2021, the consolidated statement of shareholders' equity for the three-month periods ended March 31, 2022 and 2021, June 30, 2022 and 2021, and September 30, 2022 and 2021, and the consolidated statement of cash flows for the nine-month periods ended September 30, 2022 and 2021. Results of operations for interim periods are not necessarily indicative of results for the entire year. As a result, these financial statements should be read in conjunction with the financial statements and notes thereto included in the Company's annual report on Form 10-K for the year ended December 31, 2021 (2021 Annual Report). Market Conditions: The impact of the Coronavirus Disease 2019 (COVID-19) global pandemic on the Company continues to evolve and the continued path of the global economic recovery remains uncertain given the potential longer term impacts of the pandemic. For example, economic conditions have acted as headwinds to sales in the first nine months of 2022, particularly in Japan and most notably in the first quarter with a gradually decreasing impact in the second and third quarters, pressuring net earned premiums. Further, in the U.S., supply shortages, upward pressure on wages to attract employees and higher commodity prices have all driven near-term increases in inflation. Central bank and government efforts to control inflation, as well the impacts of the Russia-Ukraine conflict, including volatility in energy prices and additional disruptions in the global supply chain, have led to slower economic growth in Japan and the U.S. Additionally, continued widening of the differential between U.S. and Japan interest rates has contributed to a weakening of the yen, which has the effect of suppressing the Company's current period results in relation to the comparable prior period. 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 Accounting Pronouncements Pending Adoption 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 will significantly change how insurers account for long-duration contracts. The amendments will change existing recognition, measurement, presentation, and disclosure requirements. Issues addressed in the new guidance include: 1) a requirement to review and, if there is a change, update assumptions for the liability for future policy benefits (LFPB) at least annually, and to update the discount rate assumption quarterly, 2) accounting for market risk benefits at fair value, 3) simplified amortization for deferred acquisition costs, and 4) enhanced financial statement presentation and disclosures. In November 2019, the FASB issued an amendment extending the effective date for public business entities that meet the definition of a Securities and Exchange Commission (SEC) filer, excluding entities eligible to be small reporting companies as defined by the SEC, by one year. In November 2020, the FASB issued an amendment providing an additional year deferral for all insurance entities due to the impact of COVID-19. The amendments are now effective for the Company for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2022. Early application of the amendments is permitted. The Company continues to evaluate the impact of adoption and has determined that the adoption will have a significant impact on the Company’s financial position, results of operations, and disclosures. The requirement to update assumptions for LFPB will have a significant impact on the Company's results of operations, systems, processes and controls and the requirement to update discount rates will have a significant impact on its equity. As part of working toward implementation of the updated standard, the Company has made key accounting policy decisions, including processes to identify insurance policy groupings (cohorts) for LFPB measurement and DAC amortization purposes, applicable discount rates, development of liability cash flow and claim expense assumptions, and DAC amortization methodology. The Company will not early adopt the updated standard and has selected the modified retrospective transition method, which requires the amended guidance be applied as of the beginning of the earliest period presented beginning 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 calculates the ratio of expected benefits less existing carrying values to gross premiums (net premium ratio) using updated assumptions and the discount rate immediately before the Transition Date. For any cohorts that have a net premium ratio greater than 100% on the Transition Date, the net premium ratio is capped at 100%. The Company uses the net premium ratio calculated on the Transition Date (and capped at 100% if required) to calculate the LFPB using 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 net premium ratio capped at 100% on the Transition Date, 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 is recorded as an adjustment (decrease) to opening retained earnings. For all cohorts on the Transition Date, 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) is recorded in accumulated other comprehensive income (AOCI) net of tax at transition. When the Company adopts the updated standard beginning January 1, 2023, opening equity will be adjusted for the Transition Date impacts to AOCI and retained earnings and prior periods presented (years 2021 and 2022) will be restated following the updated standard. Based on the modified retrospective transition method, the Transition Date impact from adoption will result in a decrease in AOCI of approximately $18.6 billion and a decrease in retained earnings of approximately $0.3 billion. The Company has designed its discount rate methodology for both the U.S. and Japan insurance business. The methodology incorporates constructing a discount rate curve separately for discounting cash flows used to calculate the U.S. and Japan LFPB, with each curve intended to be reflective of the currency, tenor and characteristics of the insurance liabilities. Discount rates comprising each curve will be 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, 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. Discount rates are updated each reporting period. Long duration insurance contracts issued by the Company will be grouped into annual calendar-year cohorts based on the contract issue date, reportable segment, legal entity and product type. Limited pay contracts will be grouped into separate cohorts from other traditional products in the same manner and will be further separated based on their premium payment structures. Riders will be combined with base policies with similar insurance coverage types and the same contract issue years. In addition to the policy elections related to cohorts and LFPB discount rates directly impacting Transition Date AOCI, the Company has also made the following accounting policy elections relevant to the post-Transition Date accounting: • All payments under an insurance contract including future expected claims and already incurred claims (i.e., claim liabilities) and related expenses will be measured together as an integrated reserve. This will result in the following presentation changes in the consolidated balance sheet: (i) unpaid policy claims on long-duration insurance contracts and accrued claim adjustment expenses presented separately pre-adoption will be presented as part of LFPB; and (ii) liabilities for fixed annuity benefits will be excluded from the integrated reserve, as they are outside the scope of the amended standard, and will be presented in other policyholders' funds. • Cash flow assumptions underlying insurance liabilities will be evaluated as to whether an update is needed at least annually in the same fiscal quarter each year. To facilitate the review, experience studies will be performed annually in the consistent quarter year-to-year to substantiate assumptions, including mortality, morbidity, and terminations in future periods. • Locked-in discount rates used for the computation of interest accretion on LFPB for policies issued on or after January 1, 2021 will be determined 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 over 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 will remain unchanged after the calendar year of issue. Locked-in discount rates on the policies held at Transition Date reflect the locked-in rates in existence immediately before the Transition Date. • For DAC amortization, the Company has elected to group insurance policies into cohorts that are consistent with the groupings used in estimating the associated LFPB. DAC will be amortized on a constant-level basis for the grouped contracts over the expected remaining term of the related contracts. For both life and health products issued by Aflac Japan, the constant-level basis used will be units in force, which is a proxy for face amount and insurance in force, respectively. For life products issued by Aflac U.S., the constant level basis used will be face amount of policies in force; for health products issued by Aflac U.S., the constant level basis used will be the number of policies in force. • The Company has made an entity-wide election to use locked-in claim expense assumptions determined for each issue-year cohort as a percentage of paid claims; these assumptions would remain unchanged over the term of the insurance policy. Under the amended guidance, certain insurance commissions and expenses must be excluded from the expense assumption, which will result in an increase in the deferred profit liability on limited-payment products compared to current guidance. In conjunction with the adoption of the updated standard effective January 1, 2023, the Company will change 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 statement of earnings. This reclassification will have no impact on net earnings. The change in presentation will be made for all comparative periods presented. The Company has created a governance framework and a plan to support implementation of the updated standard. As part of its implementation plan, the Company continues to advance the modernization of its actuarial technology platform to enhance its modeling, data management, experience study and analytical capabilities, increase the end-to-end automation of key reporting and analytical processes and optimize its control framework. The Company has also put in place internal controls related to the new processes created as part of implementing the updated standard and will continue to refine and maturate these internal controls until the formal implementation in the first quarter of 2023. The Company continues testing its reporting and disclosure capabilities under the new ASU for post-Transition Date accounting periods. The Company currently has no products with market risk benefits. Impacts on Previously Reported Results Impacts from the adoption of ASU 2018-12 to the Company's previously reported results are expected to be as follows: Consolidated Statement of Earnings Year Ended December 31, 2021 (In millions) As Adoption As Revenues: Net earned premiums, principally supplemental health insurance (1) $ 17,647 $ (552) $ 17,095 Net investment income 3,818 0 3,818 Net investment gains (losses) 468 0 468 Other income (loss) 173 0 173 Total revenues 22,106 (552) 21,554 Benefits and expenses: Benefits and claims, excluding reserve remeasurement (1)(2) 10,576 47 10,623 Reserve remeasurement (gains) losses (3) 0 (147) (147) Total benefits and claims, net 10,576 (100) 10,476 Acquisition and operating expenses: Amortization of deferred policy acquisition costs (4) 1,170 (335) 835 Insurance commissions 1,256 0 1,256 Insurance and other expenses (5) 3,544 (3) 3,541 Interest expense 238 0 238 Total acquisition and operating expenses 6,208 (338) 5,870 Total benefits and expenses 16,784 (438) 16,346 Earnings before income taxes 5,322 (114) 5,208 Income taxes (6) 997 (20) 977 Net earnings $ 4,325 $ (94) $ 4,231 (1) Adjustment reflects a $489 increase in the deferred profit liability on limited-payment products under the updated standard combined with the reclassification of a $63 increase in deferred profit liability previously reported in benefits and claims and reclassified to net earned premiums in conjunction with adoption of the updated standard.

Segment Reporting [Abstract]
BUSINESS SEGMENT INFORMATION	BUSINESS SEGMENT INFORMATION The Company consists of two reportable insurance business segments: Aflac Japan and Aflac U.S., both of which sell supplemental health and life insurance. In addition, the Parent Company, other operating business units that are not individually reportable, and business activities, including reinsurance retrocession activities, not included in Aflac Japan or Aflac U.S. are included in Corporate and other. The Company does not allocate corporate overhead expenses to business segments. Consistent with U.S. GAAP accounting guidance for segment reporting, the Company evaluates and manages its business segments using a financial performance measure called pretax adjusted earnings. Adjusted earnings are adjusted revenues less benefits and adjusted expenses. The adjustments to both revenues and expenses account for certain items that cannot be predicted or that are outside management’s control. Adjusted revenues are U.S. GAAP total revenues excluding net investment gains and losses, except for amortized hedge costs/income related to foreign currency exposure management strategies and net interest cash flows from derivatives associated with certain investment strategies. Adjusted expenses are U.S. GAAP total acquisition and operating expenses including the impact of interest cash flows from derivatives associated with notes payable but excluding any nonrecurring or other items not associated with the normal course of the Company’s insurance operations and that do not reflect the Company's underlying business performance. The Company excludes income taxes related to operations to arrive at pretax adjusted earnings.

During the first nine months of 2022 and 2021, respectively, the Company did not reclassify any investments from the held-to-maturity category to the available-for-sale category. Contractual and Economic Maturities The contractual and economic maturities of the Company's investments in fixed maturity securities at September 30, 2022, were as follows: (In millions) Amortized (1) Fair Available for sale: Due in one year or less $ 1,285 $ 1,455 Due after one year through five years 7,261 7,815 Due after five years through 10 years 13,081 14,297 Due after 10 years 47,445 48,067 Mortgage- and asset-backed securities 1,963 2,009 Total fixed maturity securities available for sale $ 71,035 $ 73,643 Held to maturity: Due in one year or less $ 0 $ 0 Due after one year through five years 37 39 Due after five years through 10 years 9,285 10,498 Due after 10 years 8,144 9,548 Mortgage- and asset-backed securities 0 0 Total fixed maturity securities held to maturity $ 17,466 $ 20,085 (1) Net of allowance for credit losses Economic maturities are used for certain debt instruments with no stated maturity where the expected maturity date is based on the combination of features in the financial instrument such as the right to call or prepay obligations or changes in coupon rates. Investment Concentrations The Company's process for investing in credit-related investments begins with an independent approach to underwriting each issuer's fundamental credit quality. The Company evaluates independently those factors that it believes could influence an issuer's ability to make payments under the contractual terms of the Company's instruments. This includes a thorough analysis of a variety of items including the issuer's country of domicile (including political, legal, and financial considerations); the industry in which the issuer competes (with an analysis of industry structure, end-market dynamics, and regulation); company specific issues (such as management, assets, earnings, cash generation, and capital needs); and contractual provisions of the instrument (such as financial covenants and position in the capital structure). The Company further evaluates the investment considering broad business and portfolio management objectives, including asset/liability needs, portfolio diversification, and expected income.

For any of its fixed maturity securities with significant declines in fair value, the Company performs detailed analyses to identify whether the drivers of the declines are due to general market drivers, such as the recent rise in interest rates, or due to credit-related factors. Identifying the drivers of the declines in fair value helps to align and allocate the Company‘s resources to securities with real credit-related concerns that could impact ultimate collection of principal and interest. For any significant declines in fair value determined to be non-interest rate or market related, the Company performs a more focused review of the related issuers' specific credit profile. For corporate issuers, the Company evaluates their assets, business profile including industry dynamics and competitive positioning, financial statements and other available financial data. For non-corporate issuers, the Company analyzes all sources of credit support, including issuer-specific factors. The Company utilizes information available in the public domain and, for certain private placement issuers, from consultations with the issuers directly. The Company also considers ratings from Nationally Recognized Statistical Rating Organizations (NRSROs), as well as the specific characteristics of the security it owns including seniority in the issuer's capital structure, covenant protections, or other relevant features. From these reviews, the Company evaluates the issuers' continued ability to service the Company's investment through payment of interest and principal. Assuming no credit-related factors develop, unrealized gains and losses on fixed maturity securities are expected to diminish as investments near maturity. Based on its credit analysis, the Company believes that the issuers of its fixed maturity investments in the sectors shown in the table above have the ability to service their obligations to the Company, and the Company does not intend to sell the investments and it is not more likely than not that the Company will be required to sell the investments before recovery of their amortized cost bases, which may be at maturity. However, from time to time the Company identifies certain available-for-sale fixed maturity securities where the amortized cost basis exceeds the present value of the cash flows expected to be collected due to credit related factors and as a result, a credit allowance will be estimated. Refer to the Allowance for Credit Losses section below for additional information. Commercial Mortgage and Other Loans The Company classifies its transitional real estate loans (TREs), commercial mortgage loans (CMLs) and middle market loans (MMLs) as held-for-investment and includes them in the commercial mortgage and other loans line on the consolidated balance sheets. The Company carries them on the balance sheet at amortized cost less an estimated allowance for credit losses. The following table reflects the composition of the carrying value for commercial mortgage and other loans by property type as of the periods presented. (In millions) September 30, 2022 December 31, 2021 Amortized Cost % of Total Amortized Cost % of Total Commercial Mortgage and other loans: Transitional real estate loans: Office $ 2,121 15.5 % $ 2,001 16.7 % Retail 485 3.6 267 2.2 Apartments/Multi-Family 2,730 20.0 1,893 15.8 Industrial 154 1.1 94 .8 Hospitality 835 6.1 876 7.3 Other 177 1.3 228 1.9 Total transitional real estate loans 6,502 47.6 5,359 44.7 Commercial mortgage loans: Office 390 2.9 398 3.3 Retail 312 2.3 332 2.8 Apartments/Multi-Family 634 4.6 649 5.4 Industrial 691 5.1 525 4.4 Total commercial mortgage loans 2,027 14.9 1,904 15.9 Middle market loans 5,112 37.5 4,697 39.4 Total commercial mortgage and other loans $ 13,641 100.0 % $ 11,960 100.0 % Allowance for credit losses (182) (174) Total net commercial mortgage and other loans $ 13,459 $ 11,786 CMLs and TREs were secured by properties entirely within the U.S. (with the largest concentrations in California (19%), Texas (13%) and Florida (10%)). Middle market loans are issued only to companies domiciled within the U.S. and Canada. Transitional Real Estate Loans TREs are commercial mortgage loans that are typically relatively short-term floating rate instruments secured by a first lien on the property. These loans provide funding for properties undergoing a change in their physical characteristics and/or economic profile and do not typically require any principal repayment prior to the maturity date. This loan portfolio is generally considered to be investment grade. As of September 30, 2022, the Company had $982 million in outstanding commitments to fund TREs. These commitments are contingent on the final underwriting and due diligence to be performed. Commercial Mortgage Loans CMLs are typically fixed rate loans on commercial real estate with partial repayment of principal over the life of the loan with the remaining outstanding principal being repaid upon maturity. This loan portfolio is generally considered higher quality investment grade loans. Middle Market Loans MMLs are typically first lien senior secured cash flow loans to small to mid-size companies for working capital, refinancing, acquisition, and recapitalization. These loans are generally considered to be below investment grade. The carrying value for MMLs included $14 million and $11 million for a short term credit facility that is reflected in other liabilities on the consolidated balance sheets, as of September 30, 2022, and December 31, 2021, respectively. As of September 30, 2022, the Company had commitments of approximately $442 million to fund future MMLs. These commitments are contingent upon the availability of middle market loans that meet the Company's underwriting criteria. Credit Quality Indicators For TREs, the Company’s key credit quality indicator is loan-to-value (LTV). Given that TRE loans involve properties undergoing renovation or construction, LTV provides the most insight into the credit risk of the loan. The Company monitors the performance of the loans periodically, but not less frequently than quarterly. For CMLs, the Company’s key credit quality indicators include LTV and debt service coverage ratios (DSCR). LTV is calculated by dividing the current outstanding loan balance by the most recent estimated property value. DSCR is the most recently available operating income of the underlying property compared to the required debt service of the loan. For MMLs and held-to-maturity fixed maturity securities, the Company’s key credit quality indicator is credit ratings. The Company’s held-to-maturity portfolio is composed of investment grade securities that are senior unsecured instruments, while its MMLs generally have below-investment-grade ratings but are typically senior secured instruments. The Company monitors the credit ratings periodically, but not less frequently than quarterly. For the Company’s reinsurance recoverable balance, the key credit quality indicator is the credit rating of the Company’s reinsurance counterparty. The Company uses external credit ratings focused on the reinsurer’s financial strength and credit worthiness. As of September 30, 2022, the Company's reinsurance counterparties were rated A+. The Company monitors the credit ratings periodically, but not less frequently than quarterly. The following tables present as of September 30, 2022 the amortized cost basis of TREs, CMLs and MMLs by year of origination and credit quality indicator .

For held-to-maturity fixed maturity securities, MMLs, and MML commitments, the Company groups assets by credit ratings, industry, and country. The Company groups CMLs and TREs and respective loan commitments by property type, property location and the property’s LTV and debt service coverage ratios. The credit allowance for the reinsurance recoverable balance is estimated using a probability-of-default (PD) / loss-given-default (LGD) method. The credit allowance for held-to-maturity fixed maturity securities and loan receivables is estimated using a PD / LGD method, discounted for the time value of money. For held-to-maturity fixed maturity securities, available-for-sale fixed maturity securities and loan receivables, the Company includes the change in present value due to the passage of time in the change in the allowance for credit losses. The Company’s methodology for estimating credit losses utilizes the contractual maturity date of the financial asset, adjusted when necessary to reflect the expected timing of repayment (such as prepayment options, renewal options, call options, or extension options). The Company applies reasonable and supportable forecasts of macroeconomic variables that impact the determination of PD/LGD over a two-year period for held-to-maturity fixed maturity securities and MMLs. The Company reverts to historical loss information over one year, following the two-year forecast period. For the CML and TRE portfolio, the Company applies reasonable and supportable forecasts of macroeconomic variables as well as national and local real-estate market factors to estimate future credit losses where the market factors revert back to historical levels over time with the period being dependent on current market conditions, projected market conditions and difference in the current and historical market levels for each factor. The Company continuously monitors the estimation methodology, due to changes in portfolio composition, changes in underwriting practices and significant events or conditions and makes adjustments as necessary. The Company’s held-to-maturity fixed maturity portfolio includes Japan Government and Agency securities of $16.6 billion amortized cost as of September 30, 2022 that meet the requirements for zero-credit-loss expectation and therefore these asset classes have been excluded from the current expected credit loss measurement. An investment in an available-for-sale fixed maturity security may be impaired if the fair value falls below amortized cost. The Company regularly reviews its fixed maturity security investments portfolio for declines in fair value. The Company's debt impairment model focuses on the ultimate collection of the cash flows from its investments and whether the Company has the intent to sell or if it is more likely than not the Company would be required to sell the security prior to recovery of its amortized cost. The determination of the amount of impairments under this model is based upon the Company's periodic evaluation and assessment of known and inherent risks associated with the respective securities. Such evaluations and assessments are revised as conditions change and new information becomes available. When determining the Company's intention to sell a security prior to recovery of its fair value to amortized cost, the Company evaluates facts and circumstances such as, but not limited to, future cash flow needs, decisions to reposition its security portfolio, and risk profile of individual investment holdings. The Company performs ongoing analyses of its liquidity needs, which includes cash flow testing of its policy liabilities, debt maturities, projected dividend payments, and other cash flow and liquidity needs. The Company’s methodology for estimating credit losses for available-for-sale fixed maturity securities utilizes the discounted cash flow model, based on past events, current market conditions and future economic conditions, as well as industry analysis and credit ratings of the fixed maturity securities. In addition, the Company evaluates the specific issuer’s probability of default and expected recovery of its position in the event of default based on the underlying financial condition and assets of the borrower as well as seniority and/or security of other debt holders in the issuer when developing management’s best estimate of expected cash flows. The Company granted certain loan modifications in its MML and TRE portfolios during the nine-month period ended September 30, 2022. As of September 30, 2022, these loan modifications did not have a material impact on the Company’s results of operations. The Company had no troubled debt restructurings (TDRs) during the nine-month periods ended September 30, 2022 and 2021, respectively. The Company designates nonaccrual status for a nonperforming debt security or a loan that is not generating its stated interest rate because of nonpayment of periodic interest by the borrower. The Company applies the cash basis method to record any payments received on non-accrual assets. The Company resumes the accrual of interest on fixed maturity securities and loans that are currently making contractual payments or for those that are not current where the borrower has paid timely (less than 30 days outstanding). As of September 30, 2022 and December 31, 2021, the Company had an immaterial amount of loans and fixed maturity securities on nonaccrual status. The following table presents the roll forward of the allowance for credit losses by portfolio segment.

The estimate of credit losses for loan commitments as of September 30, 2022 was $26 million. Other Investments The table below reflects the composition of the carrying value for other investments as of the periods presented. (In millions) September 30, December 31, 2021 Other investments: Policy loans $ 195 $ 236 Short-term investments (1) 1,816 1,726 Limited partnerships 2,145 1,858 Other 30 22 Total other investments $ 4,186 $ 3,842 (1) Includes securities lending collateral The Parent Company invests in partnerships that specialize in rehabilitating historic structures or the installation of solar equipment in order to receive federal historic rehabilitation and solar tax credits. These investments are classified as limited partnerships and included in other investments in the consolidated balance sheet. The change in value of each investment is recorded as a reduction to net investment income. Tax credits generated by these investments are recorded as an income tax benefit in the consolidated statement of earnings. As of September 30, 2022, the Company had $2.1 billion in outstanding commitments to fund alternative investments in limited partnerships. Variable Interest Entities (VIEs) As a condition of its involvement or investment in a VIE, the Company enters into certain protective rights and covenants that preclude changes in the structure of the VIE that would alter the creditworthiness of the Company's investment or its beneficial interest in the VIE. For those VIEs other than certain unit trust structures, the Company's involvement is passive in nature. The Company is not, nor has it been, required to purchase any securities issued in the future by these VIEs. The Company's ownership interest in VIEs is limited to holding the obligations issued by them. The Company has no direct or contingent obligations to fund the limited activities of these VIEs, nor does it have any direct or indirect financial guarantees related to the limited activities of these VIEs. The Company has not provided any assistance or any other type of financing support to any of the VIEs it invests in, nor does it have any intention to do so in the future. For those VIEs in which the Company holds debt obligations, the weighted-average lives of the Company's notes are very similar to the underlying collateral held by these VIEs where applicable. The Company's risk of loss related to its interests in any of its VIEs is limited to the carrying value of the related investments held in the VIE. VIEs - Consolidated The following table presents the cost or amortized cost, fair value and balance sheet caption in which the assets and liabilities of consolidated VIEs are reported. Investments in Consolidated Variable Interest Entities September 30, 2022 December 31, 2021 (In millions) Amortized (1) Fair Amortized Cost (1) Fair Assets: Fixed maturity securities, available for sale $ 2,908 $ 3,617 $ 3,264 $ 4,490 Commercial mortgage and other loans 10,775 10,716 9,740 9,910 Other investments (2) 1,815 1,815 1,535 1,535 Other assets (3) 65 65 78 78 Total assets of consolidated VIEs $ 15,563 $ 16,213 $ 14,617 $ 16,013 Liabilities: Other liabilities (3) $ 463 $ 463 $ 414 $ 414 Total liabilities of consolidated VIEs $ 463 $ 463 $ 414 $ 414 (1) Net of allowance for credit losses (2) Consists entirely of alternative investments in limited partnerships (3) Consists entirely of derivatives The Company is substantively the only investor in the consolidated VIEs listed in the table above. As the sole investor in these VIEs, the Company has the power to direct the activities of a variable interest entity that most significantly impact the entity's economic performance and is therefore considered to be the primary beneficiary of the VIEs that it consolidates. The Company also participates in substantially all of the variability created by these VIEs. The activities of these VIEs are limited to holding invested assets and foreign currency swaps, as appropriate, and utilizing the cash flows from these securities to service its investment. Neither the Company nor any of its creditors are able to obtain the underlying collateral of the VIEs unless there is an event of default or other specified event. For those VIEs that contain a swap, the Company is not a direct counterparty to the swap contracts and has no control over them. The Company's loss exposure to these VIEs is limited to its original investment. The Company's consolidated VIEs do not rely on outside or ongoing sources of funding to support their activities beyond the underlying collateral and swap contracts, if applicable. With the exception of its investment in unit trust structures, the underlying collateral assets and funding of the Company's consolidated VIEs are generally static in nature. Investments in Unit Trust Structures The Company also utilizes unit trust structures in its Aflac Japan segment to invest in various asset classes. As the sole investor of these VIEs, the Company is required to consolidate these trusts under U.S. GAAP. VIEs - Not Consolidated The table below reflects the amortized cost, fair value and balance sheet caption in which the Company's investment in VIEs not consolidated are reported.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
DERIVATIVE INSTRUMENTS	DERIVATIVE INSTRUMENTS The Company's freestanding derivative financial instruments have historically consisted of: • foreign currency forwards and options used in hedging foreign exchange risk on U.S. dollar-denominated investments in Aflac Japan's portfolio, with options used on a standalone basis and/or in a collar strategy; • foreign currency forwards and options used to economically hedge certain portions of forecasted cash flows denominated in yen and hedge the Company's long term exposure to a weakening yen; • cross-currency interest rate swaps, also referred to as foreign currency swaps, associated with certain senior notes and subordinated debentures; • foreign currency swaps that are associated with variable interest entity (VIE) bond purchase commitments, and investments in special-purpose entities, including VIEs where the Company is the primary beneficiary; • interest rate swaps used to economically hedge interest rate fluctuations in certain variable-rate investments; • interest rate swaptions used to hedge changes in the fair value associated with interest rate fluctuations for certain U.S. dollar-denominated available-for-sale fixed-maturity securities; and • bond purchase commitments at the inception of investments in consolidated VIEs. Some of the Company's derivatives are designated as cash flow hedges, fair value hedges or net investment hedges; however, other derivatives do not qualify for hedge accounting or the Company elects not to designate them as accounting hedges. Derivative Types Foreign currency forwards and options are executed for the Aflac Japan segment in order to hedge the currency risk on the carrying value of certain U.S. dollar-denominated investments. The average maturity of these forwards and options can change depending on factors such as market conditions and types of investments being held. In situations where the maturity of the forwards and options is shorter than the underlying investment being hedged, the Company may enter into new forwards and options near maturity of the existing derivative in order to continue hedging the underlying investment. In forward transactions, Aflac Japan agrees with another party to buy a fixed amount of yen and sell a corresponding amount of U.S. dollars at a specified future date. The Company also uses one-sided foreign currency put options to mitigate the settlement risk on U.S. dollar-denominated assets related to extreme foreign currency rate changes. From time to time, Aflac Japan also executes foreign currency option transactions in a collar strategy, where Aflac Japan agrees with another party to simultaneously purchase put options and sell call options. In the purchased put transactions, Aflac Japan obtains the option to buy a fixed amount of yen and sell a corresponding amount of U.S. dollars at a specified future date. In the sold call transactions, Aflac Japan agrees to sell a fixed amount of yen and buy a corresponding amount of U.S. dollars at a specified future date. The combination of purchasing the put option and selling the call option results in no net premium being paid (i.e. a costless or zero-cost collar). In 2021, the Company moved to a strategy that contains one-sided put options, fewer foreign currency forwards and no collars. From time to time, the Company may also enter into foreign currency forwards and options to hedge the currency risk associated with the net investment in Aflac Japan. In these forward transactions, the Company agrees with another party to buy a fixed amount of U.S. dollars and sell a corresponding amount of yen at a specified price at a specified future date. In the option transactions, the Company may use a combination of foreign currency options to protect expected future cash flows by simultaneously purchasing yen put options (options that protect against a weakening yen) and selling yen call options (options that limit participation in a strengthening yen). The combination of these two actions create a zero-cost collar. Additionally, the Company enters into purchased options to hedge cash flows from the net investment in Aflac Japan. The Company enters into foreign currency swaps pursuant to which it exchanges an initial principal amount in one currency for an initial principal amount of another currency, with an agreement to re-exchange the principal amounts at a future date. There may also be periodic exchanges of payments at specified intervals based on the agreed upon rates and notional amounts. Foreign currency swaps are used primarily in the consolidated VIEs in the Company's Aflac Japan portfolio to convert foreign-denominated cash flows to yen, the functional currency of Aflac Japan, in order to minimize cash flow fluctuations. The Company also uses foreign currency swaps to economically convert certain of its U.S. dollar-denominated senior note and subordinated debenture principal and interest obligations into yen-denominated obligations. In order to reduce investment income volatility from its variable-rate investments, the Company enters into receive–fixed, pay–floating interest rate swaps. These derivatives are cleared and settled through a central clearinghouse. Swaptions are used to mitigate the adverse impact resulting from significant changes in the fair value of U.S. dollar-denominated available-for-sale securities due to fluctuation in interest rates. In a payer swaption, the Company pays a premium to obtain the right, but not the obligation, to enter into a swap contract where it will pay a fixed rate and receive a floating rate. Interest rate swaption collars are combinations of two swaption positions. In order to maximize the efficiency of the collars while minimizing cost, a collar strategy is used whereby the Company purchases a long payer swaption (the Company purchases an option that allows it to enter into a swap where the Company will pay the fixed rate and receive the floating rate of the swap) and sells a short receiver swaption (the Company sells an option that provides the counterparty with the right to enter into a swap where the Company will receive the fixed rate and pay the floating rate of the swap). The combination of purchasing the long payer swaption and selling the short receiver swaption results in no net premium being paid (i.e. a costless or zero-cost collar). Bond purchase commitments result from repackaged bond structures that are consolidated VIEs whereby there is a delay in the trade date and settlement date of the bond within the structure to ensure completion of all necessary legal agreements to support the consolidated VIE that issues the repackaged bond. Since the Company has a commitment to purchase the underlying bond at a specified price, the agreement meets the definition of a derivative where the value is derived based on the current market value of the bond compared to the fixed purchase price to be paid on the settlement date. Derivative Balance Sheet Classification The table below summarizes the balance sheet classification of the Company's derivative fair value amounts, as well as the gross asset and liability fair value amounts. The fair value amounts presented do not include income accruals. Derivative assets are included in “Other Assets,” while derivative liabilities are included in “Other Liabilities” within the Company’s Consolidated Balance Sheets. The notional amount of derivative contracts represents the basis upon which pay or receive amounts are calculated and are not reflective of exposure or credit risk.

The Company has designated foreign currency swaps as a hedge of the variability in cash flows of a forecasted transaction or of amounts to be received or paid related to a recognized asset (“cash flow” hedge). The remaining maximum length of time for which these cash flows are hedged is approximately four years. The derivatives in the Company's consolidated VIEs that are not designated as accounting hedges are discussed in the "non-qualifying strategies" section of this note. Fair Value Hedges The Company designates and accounts for certain foreign currency forwards, options, and interest rate swaptions as fair value hedges when they meet the requirements for hedge accounting. The Company recognizes gains and losses on these derivatives as well as the offsetting gain or loss on the related hedged items in current earnings. Foreign currency forwards and options hedge the foreign currency exposure of certain U.S. dollar-denominated available-for-sale fixed-maturity investments held in Aflac Japan. The change in the fair value of the foreign currency forwards related to the changes in the difference between the spot rate and the forward price is excluded from the assessment of hedge effectiveness. The change in fair value of the foreign currency option related to the time value of the option is recognized in current earnings and is excluded from the assessment of hedge effectiveness. Interest rate swaptions hedge the interest rate exposure of certain U.S. dollar-denominated available-for-sale securities held in Aflac Japan. For these hedging relationships, the Company excludes time value from the assessment of hedge effectiveness and recognizes changes in the intrinsic value of the swaptions in current earnings within net investment income. The change in the time value of the swaptions is recognized in other comprehensive income (loss) and amortized into earnings (net investment income) over its legal term. The following table presents the gains and losses on derivatives and the related hedged items in fair value hedges.

It also includes the change in the fair value of the interest rate swaptions related to the time value of the swaptions which is recognized as a component of other comprehensive income (loss). (2) Gains and losses on foreign currency forwards and options and related hedged items are reported in the consolidated statement of earnings as net investment gains (losses). For interest rate swaptions and related hedged items, gains and losses included in the hedge assessment, premium amortization and time value amortization while the hedge items are still outstanding are reported within net investment income. The time value gains and losses for interest rate swaptions when the related hedged items are redeemed are reported in net investment gains and losses consistent with the impact of the hedged item. For the three-month and nine-month periods ended September 30, 2022 and 2021, gains and losses included in the hedge assessment on interest rate swaptions and related hedged items were immaterial. The following table shows the carrying amounts of assets designated and qualifying as hedged items in fair value hedges of interest rate risk and the related cumulative hedge adjustment included in the carrying amount. (In millions) Carrying Amount of the Hedged Assets/(Liabilities) (1) Cumulative Amount of Fair Value Hedging Adjustment Included in the Carrying Amount of Hedged Assets/(Liabilities) September 30, December 31, 2021 September 30, December 31, 2021 Fixed maturity securities $ 2,166 $ 3,038 $ 193 $ 205 (1) The balance includes hedging adjustment on discontinued hedging relationships of $193 in 2022 and $205 in 2021. Net Investment Hedge The Company's investment in Aflac Japan is affected by changes in the yen/dollar exchange rate. To mitigate this exposure, the Parent Company's yen-denominated liabilities (see Note 8) have been designated as non-derivative hedges and certain foreign currency forwards and options have been designated as derivative hedges of the foreign currency exposure of the Company's net investment in Aflac Japan. The Company's net investment hedge was effective during the three- and nine-month periods ended September 30, 2022 and 2021, respectively. Non-qualifying Strategies For the Company's derivative instruments in consolidated VIEs that do not qualify for hedge accounting treatment, all changes in their fair value are reported in current period earnings within n et i nvestment gains (losses). The amount of gain or loss recognized in earnings for the Company's VIEs is attributable to the derivatives in those investment structures. While the change in value of the swaps is recorded through current period earnings, the change in value of the available-for-sale fixed maturity securities associated with these swaps is recorded through other comprehensive income. As of September 30, 2022, the Parent Company had $1.9 billion notional amount of cross-currency interest rate swap agreements related to certain of its U.S. dollar-denominated senior notes to effectively convert a portion of the interest on the notes from U.S dollar to Japanese yen. Changes in the values of these swaps are recorded through current period earnings. For additional information regarding these swaps, see Note 9 of the Notes to the Consolidated Financial Statements in the 2021 Annual Report. The Company uses foreign exchange forwards and options to economically mitigate the currency risk of some of its U.S. dollar-denominated loan receivables held within the Aflac Japan segment. These arrangements are not designated as accounting hedges, as the foreign currency remeasurement of the loan receivables impacts current period earnings, and substantially offsets gains and losses from foreign exchange forwards within net investment gains (losses). The Company also has certain foreign exchange forwards on U.S. dollar-denominated available-for-sale securities where hedge accounting is not being applied. The Company uses interest rate swaps to economically convert the variable rate investment income to a fixed rate on certain variable-rate investments.

(2) Gains and losses on cash flow hedges and the change in the fair value of interest rate swaptions related to the time value of the swaptions in fair value hedges are recorded as unrealized gains (losses). Gains and losses on net investment hedges related to changes in foreign currency spot rates are recorded in the unrealized foreign currency translation gains (losses) line in the consolidated statement of comprehensive income (loss). (3) Impact of cash flow hedges reported as net investment gains (losses) includes $3 of losses reclassified from accumulated other comprehensive income (loss) into earnings during the nine-month period ended September 30, 2022, and $3 of losses during the nine-month period ended September 30, 2021. In addition, $1 of losses were reclassified from accumulated other comprehensive income (loss) into earnings during the nine-month period ended September 30, 2022, and $1 of losses during the nine-month period ended September 30, 2021, related to fair value hedges excluded component. Impact shown net of effect of hedged items (see Fair Value Hedges section of this Note 4 for further detail). As of September 30, 2022, $5 million of deferred losses on derivative instruments recorded in accumulated other comprehensive income are expected to be reclassified into earnings during the next twelve months. Credit Risk Assumed through Derivatives For the foreign currency swaps associated with the Company's VIE investments for which it is the primary beneficiary, the Company bears the risk of loss due to counterparty default even though it is not a direct counterparty to those contracts. The Company is a direct counterparty to the foreign currency swaps that it has entered into in connection with certain of its senior notes and subordinated debentures; foreign currency forwards; and foreign currency options, and therefore the Company is exposed to credit risk in the event of nonperformance by the counterparties in those contracts. The risk of counterparty default for the Company's foreign currency swaps, certain foreign currency forwards, and foreign currency options is mitigated by collateral posting requirements that counterparties to those transactions must meet. As of September 30, 2022, all of the Company's derivative agreement counterparties were investment grade. The Company engages in over-the-counter (OTC) bilateral derivative transactions directly with unaffiliated third parties under International Swaps and Derivatives Association, Inc. (ISDA) agreements and other documentation. Most of the ISDA agreements also include Credit Support Annexes (CSAs) provisions, which generally provide for two-way collateral postings at the first dollar of exposure. The Company mitigates the risk that counterparties to transactions might be unable to fulfill their contractual obligations by monitoring counterparty credit exposure and collateral value while generally requiring that collateral be posted at the outset of the transaction. In addition, a significant portion of the derivative transactions have provisions that give the counterparty the right to terminate the transaction upon a downgrade of the Company's financial strength rating. The actual amount of payments that the Company could be required to make depends on market conditions, the fair value of outstanding affected transactions, and other factors prevailing at and after the time of the downgrade. The Company also engages in OTC cleared derivative transactions through regulated central clearing counterparties. These positions are marked to market and margined on a daily basis (both initial margin and variation margin), and the Company has minimal exposure to credit-related losses in the event of nonperformance by counterparties to these derivatives. Collateral posted by the Company to third parties for derivative transactions can generally be repledged or resold by the counterparties. The aggregate fair value of all derivative instruments with credit-risk-related contingent features that were in a net liability position by counterparty was approximately $1.5 billion and $904 million as of September 30, 2022, and December 31, 2021, respectively. If the credit-risk-related contingent features underlying these agreements had been triggered on September 30, 2022, the Company estimates that it would be required to post a maximum of $77 million of additional collateral to these derivative counterparties. The Company is generally allowed to sell or repledge collateral obtained from its derivative counterparties, although it does not typically exercise such rights. (See the Offsetting tables below for collateral posted or received as of the reported balance sheet dates.) Offsetting of Financial Instruments and Derivatives Most of the Company's derivative instruments are subject to enforceable master netting arrangements that provide for the net settlement of all derivative contracts between the Parent Company or its subsidiaries and the respective counterparty in the event of default or upon the occurrence of certain termination events. Collateral support agreements with the master netting arrangements generally provide that the Company will receive or pledge financial collateral at the first dollar of exposure. The Company has securities lending agreements with unaffiliated financial institutions that post collateral to the Company in return for the use of its fixed maturity and public equity securities (see Note 3). When the Company has entered into securities lending agreements with the same counterparty, the agreements generally provide for net settlement in the event of default by the counterparty. This right of set-off allows the Company to keep and apply collateral received if the counterparty failed to return the securities borrowed from the Company as contractually agreed. The tables below summarize the Company's derivatives and securities lending transactions, and as reflected in the tables, in accordance with U.S. GAAP, the Company's policy is to not offset these financial instruments in the Consolidated Balance Sheets.

Fair Value Disclosures [Abstract]
FAIR VALUE MEASUREMENTS	FAIR VALUE MEASUREMENTS Fair Value Hierarchy U.S. GAAP specifies a hierarchy of valuation techniques based on whether the inputs to those valuation techniques are observable or unobservable. These two types of inputs create three valuation hierarchy levels. Level 1 valuations reflect quoted market prices for identical assets or liabilities in active markets. Level 2 valuations reflect quoted market prices for similar assets or liabilities in an active market, quoted market prices for identical or similar assets or liabilities in non-active markets or model-derived valuations in which all significant valuation inputs are observable in active markets. Level 3 valuations reflect valuations in which one or more of the significant inputs are not observable in an active market. The following tables present the fair value hierarchy levels of the Company's assets and liabilities that are measured and carried at fair value on a recurring basis.

A third party pricing vendor has developed valuation models to determine fair values of privately issued securities and derivatives associated with VIEs. Starting in June 2021 and July 2022, respectively, these models and associated processes and controls were transitioned to and executed by Company personnel. These models are discounted cash flow (DCF) valuation models but also use information from related markets, specifically the credit default swap (CDS) market, to estimate expected cash flows. These models take into consideration any unique characteristics of the securities or derivatives and make various adjustments to arrive at an appropriate issuer-specific loss adjusted credit curve. This credit curve is then used with the relevant recovery rates to estimate expected cash flows and modeling of additional features, including illiquidity adjustments, if necessary, to price the security or derivative by discounting those loss adjusted cash flows. In cases where a credit curve cannot be developed from the specific security features, the valuation methodology takes into consideration other market observable inputs, including: 1) the most appropriate comparable security(ies) of the issuer 2) issuer-specific CDS spreads 3) bonds or CDS spreads of comparable issuers with similar characteristics such as rating, geography, or sector 4) bond indices that are comparative in rating, industry, maturity, and region. The pricing data and market quotes the Company obtains from outside sources, including third party pricing services, are reviewed internally for reasonableness. If a fair value appears unreasonable, the Company will re-examine the inputs and assess the reasonableness of the pricing data with the vendor. Additionally, the Company may compare the inputs to relevant market indices and other performance measurements. Based on management's analysis, the valuation is confirmed or may be revised if there is evidence of a more appropriate estimate of fair value based on available market data. The Company has performed verification of the inputs and calculations in any valuation models to confirm that the valuations represent reasonable estimates of fair value. For the periods presented, the Company has not adjusted the quotes or prices it obtains from the pricing services and brokers it uses. The following tables present the pricing sources for the fair values of the Company's fixed maturity and equity securities.

Derivatives The Company uses derivative instruments to manage the risk associated with certain assets. However, the derivative instrument may not be classified in the same fair value hierarchy level as the associated asset. The significant inputs to pricing derivatives are generally observable in the market or can be derived by observable market data. When these inputs are observable, the derivatives are classified as Level 2. The Company uses present value techniques to value non-option based derivatives. It also uses option pricing models to value option based derivatives. Key inputs are as follows: Instrument Type Level 2 Interest rate derivatives Swap yield curves Basic curves Interest rate volatility (1) Foreign currency exchange rate derivatives - Non-VIES (forwards, swaps and options) Foreign currency forward rates Swap yield curves Basis curves Foreign currency spot rates Cross foreign currency basis curves Foreign currency volatility (1) Foreign currency exchange rate derivatives - VIEs (swaps) Foreign currency spot rates Swap yield curves Credit default swap curves Basis curves Recovery rates Foreign currency forward rates Foreign cross currency basis curves (1) Option-based only The fair values of the foreign currency forwards and options are based on observable market inputs, therefore they are classified as Level 2. The Parent Company has cross-currency swap agreements related to certain of its U.S. dollar-denominated senior notes to effectively convert a portion of the interest on the notes from U.S dollar to Japanese yen. Their fair values are based on observable market inputs, therefore they are classified as Level 2. To determine the fair value of its interest rate derivatives, the Company uses inputs that are generally observable in the market or can be derived from observable market data. Interest rate swaps are cleared trades. In a cleared swap contract, the clearinghouse provides benefits to the counterparties similar to contracts listed for investment traded on an exchange since it maintains a daily margin to mitigate counterparties' credit risk. These derivatives are priced using observable inputs, accordingly, they are classified as Level 2. For its interest rate swaptions, the Company estimates their fair values using observable market data, including interest rate curves and volatility. Their fair values are also classified as Level 2. For derivatives associated with VIEs where the Company is the primary beneficiary, the Company is not the direct counterparty to the swap contracts. Nevertheless, the Company has full transparency into the contracts to properly value the swaps for reporting purposes. Prior to October 1, 2021, these derivatives were classified as Level 3 because certain significant inputs were determined to be unobservable, primarily due to the long duration of the swaps which required extrapolation beyond the observable limits of the curve(s). However, due to the natural aging of the swap portfolio and the continued evolution of capital market inputs, especially the availability of long-term interest rates with tenors beyond 30 years, the Company has concluded that all significant inputs are now observable. As a result, effective October 1, 2021, the Company transferred the derivatives associated with its consolidated VIEs to Level 2 of the fair value hierarchy. For forward bond purchase commitments with VIEs, the fair value of the derivative is based on the difference in the fixed purchase price and the current market value of the related bond prior to the settlement date. Since the bond is typically a public bond with readily available pricing, the derivatives associated with the forward purchase commitment are classified as Level 2 of the fair value hierarchy. Commercial mortgage and other loans Commercial mortgage and other loans include TREs, CMLs and MMLs. The Company's loan receivables do not have readily determinable market prices and generally lack market liquidity. Fair values for loan receivables are determined based on the present value of expected future cash flows discounted at the applicable U.S. Treasury or floating-rate benchmark yield plus an appropriate spread that considers other risk factors, such as credit and liquidity risk. The spreads are a significant component of the pricing inputs and are generally considered unobservable. Therefore, these investments have been assigned a Level 3 within the fair value hierarchy. Other investments Other investments includes short-term investments that are measured at fair value where amortized cost approximates fair value. Other policyholders' funds The largest component of the other policyholders' funds liability is the Company's annuity line of business in Aflac Japan. The Company's annuities have fixed benefits and premiums. For this product, the Company estimates the fair value to be equal to the cash surrender value. This is analogous to the value paid to policyholders on the valuation date if they were to surrender their policy. The Company periodically checks the cash value against discounted cash flow projections for reasonableness. The Company considers its inputs for this valuation to be unobservable and have accordingly classified this valuation as Level 3. Notes payable The fair values of the Company's publicly issued notes payable are determined by utilizing available sources of observable inputs from third party pricing vendors and are classified as Level 2. The fair values of the Company's yen-denominated loans approximate their carrying values and are classified as Level 3. Transfers between Hierarchy Levels and Level 3 Rollforward Assets and liabilities are transferred into Level 3 when a significant input cannot be corroborated with market observable data. This occurs when market activity decreases significantly and underlying inputs cannot be observed, current prices are not available, and/or when there are significant variances in quoted prices, thereby affecting transparency. Assets and liabilities are transferred out of Level 3 when circumstances change such that a significant input can be corroborated with market observable data. This may be due to a significant increase in market activity, a specific event, or one or more significant input(s) becoming observable. Effective October 1, 2021, the foreign exchange swaps discussed above were transferred from Level 3 to Level 2 because the significant inputs used for their valuation that were previously unobservable are now observable.

Included in the tables are the inputs or range of possible inputs that have an effect on the overall valuation of the financial instruments. September 30, 2022 (In millions) Fair Value Valuation Technique(s) Unobservable Input Range Assets: Securities available for sale, carried at fair value: Fixed maturity securities: Mortgage- and asset-backed securities $ 310 Consensus pricing Offered quotes N/A (a) Public utilities 507 Discounted cash flow Credit spreads N/A (a) Sovereign and supranational 34 Discounted cash flow Historical volatility N/A (a) Banks/financial institutions 148 Consensus pricing Offered quotes N/A (a) Other corporate 621 Discounted cash flow Credit spreads N/A (a) Equity securities 197 Net asset value Offered quotes N/A (a) Total assets $ 1,817 (a) N/A represents securities where the Company receives unadjusted broker quotes and for which there is no transparency into the providers' valuation techniques or unobservable inputs. December 31, 2021 (In millions) Fair Value Valuation Technique(s) Unobservable Input Range Assets: Securities available for sale, carried at fair value: Fixed maturity securities: Mortgage- and asset-backed securities $ 291 Consensus pricing Offered quotes N/A (a) Public utilities 493 Discounted cash flow Credit spreads N/A (a) Sovereign and supranational 43 Discounted cash flow Historical volatility N/A (a) Banks/financial institutions 45 Consensus pricing Offered quotes N/A (a) Other corporate 426 Discounted cash flow Credit spreads N/A (a) Equity securities 173 Net asset value Offered quotes N/A (a) Total assets $ 1,471 (a) N/A represents securities where the Company receives unadjusted broker quotes and for which there is no transparency into the providers' valuation techniques or unobservable inputs. The following is a discussion of the significant unobservable inputs or valuation techniques used in determining the fair value of securities and derivatives classified as Level 3. Net Asset Value The Company holds certain unlisted equity securities whose fair value is derived based on the financial statements published by the investee. These securities do not trade on an active market and the valuations derived are dependent on the availability of timely financial reporting of the investee. Net asset value is an unobservable input in the determination of fair value of equity securities. Offered Quotes In circumstances where the Company's valuation model price is overridden because it implies a value that is not consistent with current market conditions, the Company will solicit bids from a limited number of brokers. The Company also receives unadjusted prices from brokers for its mortgage and asset-backed securities. These quotes are non-binding but are reflective of valuation best estimates at that particular point in time. Offered quotes are an unobservable input in the determination of fair value of mortgage- and asset-backed securities, certain banks/financial institutions, certain other corporate, and equity securities investments. Interest Rates and CDS Spreads The significant drivers of the valuation of the foreign exchange swaps are interest rates and CDS spreads. Some of the Company's swaps have long maturities that increase the sensitivity of the swaps to interest rate fluctuations. For the Company's foreign exchange or cross currency swaps that are in a net asset position, an increase in yen interest rates (all other factors held constant) will decrease the present value of the yen final settlement receivable (receive leg), thus decreasing the value of the swap as long as the derivative remains in a net asset position. Foreign exchange swaps also have a lump-sum final settlement of foreign exchange principal amounts at the termination of the swap. Assuming all other factors are held constant, an increase in yen interest rates will decrease the receive leg and decrease the net value of the swap. Likewise, holding all other factors constant, an increase in U.S. dollar interest rates will increase the swap's net value due to the decrease in the present value of the dollar final settlement payable (pay leg). The extinguisher feature in most of the Company's VIE swaps results in a cessation of cash flows and no further payments between the parties to the swap in the event of a default on the referenced or underlying collateral. To price this feature, the Company applies the survival probability of the referenced entity to the projected cash flows. The survival probability uses the CDS spreads and recovery rates to adjust the present value of the cash flows. For extinguisher swaps with positive values, an increase in CDS spreads decreases the likelihood of receiving the final exchange payments and reduces the value of the swap. Effective October 1, 2021, the foreign exchange swaps mentioned above were transferred from Level 3 to Level 2 because the significant inputs used for their valuation that were previously unobservable are now observable.

Insurance Loss Reserves [Abstract]
POLICY LIABILITIES	POLICY LIABILITIES Changes in the liability for unpaid policy claims were as follows: Three Months Ended Nine Months Ended (In millions) 2022 2021 2022 2021 Unpaid supplemental health claims, beginning of period $ 3,779 $ 4,162 $ 4,067 $ 4,389 Less reinsurance recoverables 38 37 37 39 Net balance, beginning of period 3,741 4,125 4,030 4,350 Add claims incurred during the period related to: Current year 1,689 1,720 5,007 5,302 Prior years (151) (215) (512) (739) Total incurred 1,538 1,505 4,495 4,563 Less claims paid during the period on claims incurred during: Current year 1,148 1,279 2,703 2,947 Prior years 214 219 1,554 1,676 Total paid 1,362 1,498 4,257 4,623 Effect of foreign exchange rate changes on unpaid claims (105) (29) (456) (187) Net balance, end of period 3,812 4,103 3,812 4,103 Add reinsurance recoverables 50 39 50 39 Unpaid supplemental health claims, end of period 3,862 4,142 3,862 4,142 Unpaid life claims, end of period 654 767 654 767 Total liability for unpaid policy claims $ 4,516 $ 4,909 $ 4,516 $ 4,909 The incurred claims development related to prior years reflects favorable claims experience compared to previous estimates. The favorable claims development of $512 million for the nine-month period ended September 30, 2022 comprises approximately $321 million from Japan and $191 million from the U.S., representing approximately 63% and 37% of the total, respectively. Excluding the impact of foreign exchange of a loss of approximately $83 million from December 31, 2021 to September 30, 2022, the favorable claims development in Japan would have been approximately $404 million, representing approximately 79% of the total. The Company has experienced continued favorable claim trends in 2022 for its core health products in Japan. During the first nine months of 2022, there were impacts from lower utilization of healthcare services, due to the COVID-19 pandemic. This impacted both cancer and medical products, as the Japan population was avoiding doctor and hospital visits and staying home more. This resulted in lower sickness, accident, and cancer incurred claims. Although overall experience is favorable, during the first nine months of 2022, there has been an increase in medical hospitalization claims related to COVID-19, mainly due to a wider scope of "deemed hospitalization" being utilized in Japan. In addition, dating back to before the pandemic, cancer treatment patterns in Japan are continuing to be influenced by significant advances in early-detection techniques and by the increased use of pathological diagnosis rather than clinical exams. Additionally, follow-up radiation and chemotherapy treatments are occurring more often on an outpatient basis. Such changes in treatment not only increase the quality of life and initial outcomes for the patients, but also decrease the average length of each hospital stay, resulting in favorable claims development. In the first nine months of 2022, as experienced in 2021 and 2020, the incurred claims development related to prior years reflects favorable claims experience compared to previous estimates. The favorable claims trend continued for the majority of the Company's major U.S. accident and health lines of business, including accident, hospital indemnity, cancer, critical illness and short-term disability. Additionally, refinements to COVID-19 incurred estimates also contributed to the favorable development. The U.S. portion of the favorable claims development in the first nine months of 2022 includes $63 million related to refinements in the estimates for COVID-19 and non-COVID-19 claims as experience emerges.

REINSURANCE

REINSURANCE	9 Months Ended

Reinsurance Disclosures [Abstract]
REINSURANCE	REINSURANCE The Company periodically enters into fixed quota-share coinsurance agreements in the normal course of business. For each of its reinsurance agreements, the Company determines whether the agreement provides indemnification against loss or liability relating to insurance risk in accordance with applicable accounting standards. Reinsurance premiums and benefits paid or provided are accounted for on bases consistent with those used in accounting for the original policies issued and the terms of the reinsurance contracts. Premiums and benefits are reported net of insurance ceded. The Company has recorded a deferred profit liability related to reinsurance transactions. The remaining deferred profit liability of $646 million and $859 million as of September 30, 2022 and December 31, 2021, respectively, is included in future policy benefits in the consolidated balance sheet and is being amortized into income over the expected lives of the policies. The Company has also recorded a reinsurance recoverable for reinsurance transactions, which is included in other assets in the consolidated balance sheet and had a remaining balance of $761 million and $937 million as of September 30, 2022 and December 31, 2021, respectively. The spot yen/dollar exchange rate weakened by approximately 20.6% and ceded reserves decreased approximately 19.1% from December 31, 2021 to September 30, 2022. The following table reconciles direct premiums and direct benefits and claims to net amounts after the effect of reinsurance which also includes the elimination of inter-segment amounts associated with affiliated reinsurance. Three Months Ended Nine Months Ended (In millions) 2022 2021 2022 2021 Direct earned premiums $ 3,681 $ 4,426 $ 11,772 $ 13,567 Ceded to other companies: Ceded Aflac Japan closed blocks (80) (107) (266) (329) Other (20) (19) (55) (54) Assumed from other companies: Retrocession activities 35 45 112 138 Other 35 27 116 84 Net earned premiums $ 3,651 $ 4,372 $ 11,679 $ 13,406 Direct benefits and claims $ 2,385 $ 2,649 $ 7,209 $ 8,112 Ceded benefits and change in reserves for future benefits: Ceded Aflac Japan closed blocks (103) (94) (276) (288) Eliminations 5 8 17 24 Other (9) (9) (28) (25) Assumed from other companies: Retrocession activities 43 42 115 126 Eliminations (5) (8) (17) (24) Other 24 21 105 71 Benefits and claims, net $ 2,340 $ 2,609 $ 7,125 $ 7,996 These reinsurance transactions are indemnity reinsurance that do not relieve the Company from its obligations to policyholders. In the event that the reinsurer is unable to meet their obligations, the Company remains liable for the reinsured claims. As a part of its capital contingency plan, the Company entered into a committed reinsurance facility agreement on December 1, 2015, with reserves of approximately ¥120 billion as of September 30, 2022. This reinsurance facility agreement was renewed in 2021 and is effective until December 31, 2022. There are also additional commitment periods of a one-year duration, each of which are automatically extended unless notification is received from the reinsurer within 60 days prior to the expiration. The reinsurer can withdraw from the committed facility if Aflac's Standard and Poor's (S&P) rating drops below BBB-. As of September 30, 2022, the Company has not executed a reinsurance treaty under this committed reinsurance facility.

In September 2022, the Parent Company issued four series of senior notes totaling ¥73.0 billion through a public debt offering under its U.S. shelf registration statement. The first series, which totaled ¥33.4 billion, bears interest at a fixed rate of 1.075% per annum, payable semi-annually, and will mature in September 2029. The second series, which totaled ¥21.1 billion, bears interest at a fixed rate of 1.320% per annum, payable semi-annually, and will mature in December 2032. The third series, which totaled ¥6.5 billion, bears interest at a fixed rate of 1.594% per annum, payable semi-annually, and will mature in September 2037.

These notes are redeemable at the Parent Company’s option at any time, in whole but not in part, upon the occurrence of certain changes affecting U.S. taxation, as specified in the indenture governing the terms of the issuance. In addition, the notes maturing in September 2029, December 2032 and September 2037 are redeemable at the Parent Company's option, in whole or in part from time to time, on or after June 14, 2029, June 14, 2032 and March 14, 2037, respectively, at a redemption price equal to the aggregate principal amount of the applicable series to be redeemed plus accrued and unpaid interest on the principal amount to be redeemed to, but excluding, the date of redemption. In August 2022, the Parent Company renewed a senior term loan facility with a commitment amount totaling ¥107.0 billion. The first tranche of the facility, which totaled ¥11.7 billion, bears interest at a rate per annum equal to the Tokyo interbank market rate (TIBOR), or alternate TIBOR, if applicable, plus the applicable TIBOR margin and will mature in August 2027. The applicable margin ranges between .225% and .625%, depending on the Parent Company's debt ratings as of the date of determination. The second tranche, which totaled ¥25.3 billion, bears interest at a rate per annum equal to TIBOR, or alternate TIBOR, if applicable, plus the applicable TIBOR margin and will mature in August 2029. The applicable margin ranges between .325% and .725%, depending on the Parent Company's debt ratings as of the date of determination. The third tranche, which totaled ¥70.0 billion, bears interest at a rate per annum equal to TIBOR, or alternate TIBOR, if applicable, plus the applicable TIBOR margin and will mature in August 2032. The applicable margin ranges between .475% and 1.025%, depending on the Parent Company's debt ratings as of the date of determination. In September 2022, the Parent Company used a portion of the net proceeds from its September 2022 issuance of various series of senior notes and the August 2022 senior term loan facility to redeem $750 million of its 3.625% senior notes due November 2024.

INCOME TAXES	9 Months Ended

Income Tax Disclosure [Abstract]
INCOME TAXES	INCOME TAXES The Company uses a full year estimated annual effective tax rate to calculate total income tax expense on interim quarters. In addition, the Company discretely recognizes certain other items in the period in which they occur. The estimated annual effective tax rate is calculated as the ratio of projected total income tax expense divided by projected earnings before income taxes for the year. The interim period tax expense (or benefit) is the difference between the year-to-date income tax provision and the amounts reported for the previous interim periods of the year. The Company’s consolidated effective income tax rate on pretax earnings was (44.7)% and 20.2% for the three-month periods and 1.6% and 19.7% for the nine-month periods ended September 30, 2022 and 2021, respectively. This combined effective tax rate differs from the U.S. statutory rate primarily due to the impact of the tax accounting method change discussed below, as well as solar, historic and foreign tax credits. Aflac Japan holds certain U.S. dollar-denominated assets in a Delaware Statutory Trust (DST). These assets are mostly comprised of various U.S. dollar-denominated commercial mortgage loans. The functional currency of the DST for U.S. tax purposes was historically the Japanese yen. In the third quarter of 2022, the Company requested a change in tax accounting method through the Internal Revenue Service's automatic consent procedures to change its functional currency on the DST for U.S. tax purposes to the U.S. dollar. As a result, foreign currency translation gains or losses on assets held in the DST will no longer be recognized for U.S. tax purposes. The Company historically recorded a deferred tax liability for foreign currency translation gains on the DST assets, which was released in the third quarter of 2022 as a result of the functional currency change. The release of the deferred tax liability resulted in the Company recognizing an income tax benefit of $695 million ($1.10 per basic and diluted share, respectively) in the third quarter of 2022. The Company has determined that the change in tax accounting method will impact its combined effective tax rate in future periods as a function of changes in the foreign exchange rate between the Japanese yen and U.S. dollar. In August 2022, the Inflation Reduction Act of 2022 (IRA) was signed into U.S. law. Effective January 1, 2023, the law will impose a 15% alternative minimum corporate tax rate and imposes a 1% excise tax on the Company’s repurchases of its common stock. The Company does not anticipate any impacts from the new corporate minimum tax rate since its current tax rate is above the 15% minimum rate. Further, the Company expects the charges associated with the excise tax to be recognized in equity consistent with other costs related to treasury stock.

SHARE-BASED COMPENSATION

SHARE-BASED COMPENSATION	9 Months Ended
	Sep. 30, 2022
Share-Based Payment Arrangement [Abstract]
SHARE-BASED COMPENSATION	SHARE-BASED COMPENSATION As of September 30, 2022, the Company has outstanding share-based awards under the Aflac Incorporated Long-Term Incentive Plan (As Amended and Restated February 14, 2017), as further amended on August 9, 2022 (the Plan). Share-based awards are designed to reward employees for their long-term contributions to the Company and provide incentives for them to remain with the Company. The number and frequency of share-based awards are based on competitive practices, operating results of the Company, government regulations, and other factors. The Plan, allows for a maximum number of shares issuable over its term of 75 million shares including 38 million shares that may be awarded in respect of awards other than options or stock appreciation rights. If any awards granted under the Plan are forfeited or are terminated before being exercised or settled for any reason other than tax forfeiture, then the shares underlying the awards will again be available under the Plan. The Plan allows awards to Company employees for incentive stock options (ISOs), non-qualifying stock options (NQSOs), restricted stock, restricted stock units, and stock appreciation rights. Non-employee directors are eligible for grants of NQSOs, restricted stock, and stock appreciation rights. As of September 30, 2022, approximately 35.7 million shares were available for future grants under this plan. The ISOs and NQSOs have a term of 10 years, and the share-based awards generally vest upon time-based conditions or time and performance-based conditions. Time-based vesting generally occurs after three years. Performance-based vesting conditions generally include the attainment of goals related to Company financial performance. As of September 30, 2022, the only performance-based awards issued and outstanding were restricted stock awards and units. Stock options and stock appreciation rights granted under the amended Plan have an exercise price of at least the fair market value of the underlying stock on the grant date and have an expiration date no later than 10 years from the grant date. Time-based restricted stock awards, restricted stock units and stock options granted after January 1, 2017 generally vest on a ratable basis over three years, and awards granted prior to the amendment vest on a cliff basis over three years. The Compensation Committee of the Board of Directors has the discretion to determine vesting schedules. Share-based awards granted to U.S.-based grantees are settled with authorized but unissued Company stock, while those issued to Japan-based grantees are settled with treasury shares. The following table provides information on stock options outstanding and exercisable at September 30, 2022. Stock Weighted-Average Aggregate Weighted-Average Outstanding 1,657 3.0 $ 40 $ 31.88 Exercisable 1,657 3.0 40 31.88 The Company received cash from the exercise of stock options in the amount of $13 million during the first nine months of 2022, compared with $20 million in the first nine months of 2021. The tax benefit realized as a result of stock option exercises and restricted stock releases was $18 million in the first nine months of 2022, compared with $16 million in the first nine months of 2021. As of September 30, 2022, total compensation cost not yet recognized in the Company's consolidated financial statements related to restricted stock awards and units was $46 million, of which $23 million (1.8 million shares) was related to restricted stock awards and units with a performance-based vesting condition. The Company expects to recognize these amounts over a weighted-average period of approximately 1.7 years. There are no other contractual terms covering restricted stock awards once vested. The following table summarizes restricted stock activity during the nine-month period ended September 30, 2022. (In thousands of shares) Shares Weighted-Average Restricted stock at December 31, 2021 2,557 $ 49.38 Granted in 2022 1,099 66.70 Canceled in 2022 (54) 53.77 Vested in 2022 (1,127) 49.58 Restricted stock at September 30, 2022 2,475 $ 56.09 In February 2022, the Company granted 390 thousand performance-based stock awards and units, which are contingent on the achievement of the Company's financial performance metrics and its market-based conditions. On the date of grant, the Company estimated the fair value of restricted stock awards and units with market-based conditions using a Monte Carlo simulation model. The model discounts the value of the stock at the assumed vesting date based on the risk-free interest rate. Based on estimates of actual performance versus the vesting thresholds, the calculated fair value percentage pay-out estimate will be updated each quarter. The Company uses third-party analyses to assist in developing the assumptions used in, as well as calibrating, a Monte Carlo simulation model. The Company is responsible for determining the assumptions used in estimating the fair value of its share-based payment awards. For additional information on the Company's long-term share-based compensation plans and the types of share-based awards, see Note 12 of the Notes to the Consolidated Financial Statements included in the 2021 Annual Report.

Commitments and Contingencies Disclosure [Abstract]
COMMITMENTS AND CONTINGENT LIABILITIES	COMMITMENTS AND CONTINGENT LIABILITIES Effective April 1, 2022, the Company renewed an outsourcing agreement with an information technology and data services company to provide application maintenance and development services for Aflac Japan. As of September 30, 2022, the agreement has a remaining term of four years and an aggregate remaining cost of ¥6.7 billion ($46 million using the September 30, 2022 exchange rate). The Company is a defendant in various lawsuits considered to be in the normal course of business. Members of the Company's senior legal and financial management teams review litigation on a quarterly and annual basis. The final results of any litigation cannot be predicted with certainty. Although some of this litigation is pending in states where large punitive damages, bearing little relation to the actual damages sustained by plaintiffs, have been awarded in recent years, the Company believes the outcome of pending litigation will not have a material adverse effect on its financial position, results of operations, or cash flows. See Note 3 of the Notes to the Consolidated Financial Statements for details on certain investment commitments. Guaranty Fund Assessments The U.S. insurance industry has a policyholder protection system that is monitored and regulated by state insurance departments. These life and health insurance guaranty associations are state entities (in all 50 states as well as Puerto Rico and the District of Columbia) created to protect policyholders of an insolvent insurance company. All insurance companies (with limited exceptions) licensed to sell life or health insurance in a state must be members of that state’s guaranty association. Under state guaranty association laws, certain insurance companies can be assessed (up to prescribed limits) for certain obligations to the policyholders and claimants of impaired or insolvent insurance companies that write the same line or similar lines of business. In 2009, the Pennsylvania Insurance Commissioner placed long-term care insurer Penn Treaty Network America Insurance Company and its subsidiary American Network Insurance Company (collectively referred to as Penn Treaty), neither of which is affiliated with Aflac, in rehabilitation and petitioned a state court for approval to liquidate Penn Treaty. A final order of liquidation was granted by a recognized judicial authority on March 1, 2017, and as a result, Penn Treaty is in the process of liquidation. The Company estimated and recognized the impact of its share of guaranty fund assessments resulting from the liquidation using a discounted rate of 4.25%. The Company recognized a discounted liability for the assessments of $62 million (undiscounted $94 million), offset by discounted premium tax credits of $48 million (undiscounted $74 million), for a net $14 million impact to net income in the quarter ended March 31, 2017. The Company paid a majority of these assessments by September 30, 2022. The Company used the cost estimate provided as of the liquidation date by the National Organization of Life and Health Guaranty Associations (NOLHGA) to calculate its estimated assessments and tax credits. Guaranty fund assessments for the nine-month periods ended September 30, 2022 and 2021 were immaterial.

SUMMARY OF SIGNIFICANT ACCOUN_2

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	9 Months Ended
	Sep. 30, 2022
Organization, Consolidation and Presentation of Financial Statements [Abstract]
Description of Business and Basis of Presentation	Description of Business Aflac Incorporated (the Parent Company) and its subsidiaries (collectively, the Company) primarily sell supplemental health and life insurance in the United States (U.S.) and Japan. The Company's insurance business is marketed and administered through American Family Life Assurance Company of Columbus (Aflac) in the U.S. and through Aflac Life Insurance Japan Ltd. (ALIJ) in Japan. The Company’s operations consist of two reportable business segments: Aflac U.S., which includes Aflac, and Aflac Japan, which includes ALIJ. American Family Life Assurance Company of New York (Aflac New York) is a wholly owned subsidiary of Aflac. Most of Aflac's policies are individually underwritten and marketed through independent agents. With the exception of dental and vision products administered by Aflac Benefits Solutions, Inc. (ABS), formerly known as Argus Dental & Vision, Inc., and certain group life insurance products, Aflac U.S. markets and administers group products through Continental American Insurance Company (CAIC), branded as Aflac Group Insurance. The Company's insurance operations in the U.S. and Japan service the two markets for the Company's insurance business. Aflac Japan's revenues, including net gains and losses on its investment portfolio, accounted for 72% and 69% of the Company's total revenues in the nine-month periods ended September 30, 2022 and 2021, respectively. The percentage of the Company's total assets attributable to Aflac Japan was 79% at September 30, 2022, compared with 82% at December 31, 2021. Basis of Presentation The Company prepares its financial statements in accordance with U.S. generally accepted accounting principles (U.S. GAAP). These principles are established primarily by the Financial Accounting Standards Board (FASB). In these Notes to the Consolidated Financial Statements, references to U.S. GAAP issued by the FASB are derived from the FASB Accounting Standards Codification TM (ASC). The preparation of financial statements in conformity with U.S. GAAP requires the Company to make estimates based on currently available information when recording transactions resulting from business operations. The most significant items on the Company's balance sheet that involve a greater degree of accounting estimates and actuarial determinations subject to changes in the future are the valuation of investments and derivatives, deferred policy acquisition costs (DAC), liabilities for future policy benefits and unpaid policy claims, and income taxes. These accounting estimates and actuarial determinations are sensitive to market conditions, investment yields, mortality, morbidity, commission and other acquisition expenses, and terminations by policyholders. As additional information becomes available, or actual amounts are determinable, the recorded estimates are revised and reflected in operating results. Although some variability is inherent in these estimates, the Company believes the amounts provided are reasonable and reflective of the best estimates of management. The unaudited 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. In the opinion of management, the accompanying unaudited consolidated financial statements of the Company contain all adjustments, consisting of normal recurring accruals, which are necessary to fairly present the consolidated balance sheets as of September 30, 2022 and December 31, 2021, the consolidated statements of earnings and comprehensive income (loss) for the three- and nine-month periods ended September 30, 2022 and 2021, the consolidated statement of shareholders' equity for the three-month periods ended March 31, 2022 and 2021, June 30, 2022 and 2021, and September 30, 2022 and 2021, and the consolidated statement of cash flows for the nine-month periods ended September 30, 2022 and 2021. Results of operations for interim periods are not necessarily indicative of results for the entire year. As a result, these financial statements should be read in conjunction with the financial statements and notes thereto included in the Company's annual report on Form 10-K for the year ended December 31, 2021 (2021 Annual Report).
Market Conditions	Market Conditions: The impact of the Coronavirus Disease 2019 (COVID-19) global pandemic on the Company continues to evolve and the continued path of the global economic recovery remains uncertain given the potential longer term impacts of the pandemic. For example, economic conditions have acted as headwinds to sales in the first nine months of 2022, particularly in Japan and most notably in the first quarter with a gradually decreasing impact in the second and third quarters, pressuring net earned premiums. Further, in the U.S., supply shortages, upward pressure on wages to attract employees and higher commodity prices have all driven near-term increases in inflation. Central bank
Reclassifications	Reclassifications : Certain reclassifications have been made to prior-year amounts to conform to current-year reporting classifications. These reclassifications had no impact on net earnings or total shareholders' equity.
Description of Accounting Pronouncements Pending Adoption	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 will significantly change how insurers account for long-duration contracts. The amendments will change existing recognition, measurement, presentation, and disclosure requirements. Issues addressed in the new guidance include: 1) a requirement to review and, if there is a change, update assumptions for the liability for future policy benefits (LFPB) at least annually, and to update the discount rate assumption quarterly, 2) accounting for market risk benefits at fair value, 3) simplified amortization for deferred acquisition costs, and 4) enhanced financial statement presentation and disclosures. In November 2019, the FASB issued an amendment extending the effective date for public business entities that meet the definition of a Securities and Exchange Commission (SEC) filer, excluding entities eligible to be small reporting companies as defined by the SEC, by one year. In November 2020, the FASB issued an amendment providing an additional year deferral for all insurance entities due to the impact of COVID-19. The amendments are now effective for the Company for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2022. Early application of the amendments is permitted. The Company continues to evaluate the impact of adoption and has determined that the adoption will have a significant impact on the Company’s financial position, results of operations, and disclosures. The requirement to update assumptions for LFPB will have a significant impact on the Company's results of operations, systems, processes and controls and the requirement to update discount rates will have a significant impact on its equity. As part of working toward implementation of the updated standard, the Company has made key accounting policy decisions, including processes to identify insurance policy groupings (cohorts) for LFPB measurement and DAC amortization purposes, applicable discount rates, development of liability cash flow and claim expense assumptions, and DAC amortization methodology. The Company will not early adopt the updated standard and has selected the modified retrospective transition method, which requires the amended guidance be applied as of the beginning of the earliest period presented beginning 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 calculates the ratio of expected benefits less existing carrying values to gross premiums (net premium ratio) using updated assumptions and the discount rate immediately before the Transition Date. For any cohorts that have a net premium ratio greater than 100% on the Transition Date, the net premium ratio is capped at 100%. The Company uses the net premium ratio calculated on the Transition Date (and capped at 100% if required) to calculate the LFPB using 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 net premium ratio capped at 100% on the Transition Date, 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 is recorded as an adjustment (decrease) to opening retained earnings. For all cohorts on the Transition Date, 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) is recorded in accumulated other comprehensive income (AOCI) net of tax at transition. When the Company adopts the updated standard beginning January 1, 2023, opening equity will be adjusted for the Transition Date impacts to AOCI and retained earnings and prior periods presented (years 2021 and 2022) will be restated following the updated standard. Based on the modified retrospective transition method, the Transition Date impact from adoption will result in a decrease in AOCI of approximately $18.6 billion and a decrease in retained earnings of approximately $0.3 billion. The Company has designed its discount rate methodology for both the U.S. and Japan insurance business. The methodology incorporates constructing a discount rate curve separately for discounting cash flows used to calculate the U.S. and Japan LFPB, with each curve intended to be reflective of the currency, tenor and characteristics of the insurance liabilities. Discount rates comprising each curve will be 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, 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. Discount rates are updated each reporting period. Long duration insurance contracts issued by the Company will be grouped into annual calendar-year cohorts based on the contract issue date, reportable segment, legal entity and product type. Limited pay contracts will be grouped into separate cohorts from other traditional products in the same manner and will be further separated based on their premium payment structures. Riders will be combined with base policies with similar insurance coverage types and the same contract issue years. In addition to the policy elections related to cohorts and LFPB discount rates directly impacting Transition Date AOCI, the Company has also made the following accounting policy elections relevant to the post-Transition Date accounting: • All payments under an insurance contract including future expected claims and already incurred claims (i.e., claim liabilities) and related expenses will be measured together as an integrated reserve. This will result in the following presentation changes in the consolidated balance sheet: (i) unpaid policy claims on long-duration insurance contracts and accrued claim adjustment expenses presented separately pre-adoption will be presented as part of LFPB; and (ii) liabilities for fixed annuity benefits will be excluded from the integrated reserve, as they are outside the scope of the amended standard, and will be presented in other policyholders' funds. • Cash flow assumptions underlying insurance liabilities will be evaluated as to whether an update is needed at least annually in the same fiscal quarter each year. To facilitate the review, experience studies will be performed annually in the consistent quarter year-to-year to substantiate assumptions, including mortality, morbidity, and terminations in future periods. • Locked-in discount rates used for the computation of interest accretion on LFPB for policies issued on or after January 1, 2021 will be determined 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 over 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 will remain unchanged after the calendar year of issue. Locked-in discount rates on the policies held at Transition Date reflect the locked-in rates in existence immediately before the Transition Date. • For DAC amortization, the Company has elected to group insurance policies into cohorts that are consistent with the groupings used in estimating the associated LFPB. DAC will be amortized on a constant-level basis for the grouped contracts over the expected remaining term of the related contracts. For both life and health products issued by Aflac Japan, the constant-level basis used will be units in force, which is a proxy for face amount and insurance in force, respectively. For life products issued by Aflac U.S., the constant level basis used will be face amount of policies in force; for health products issued by Aflac U.S., the constant level basis used will be the number of policies in force. • The Company has made an entity-wide election to use locked-in claim expense assumptions determined for each issue-year cohort as a percentage of paid claims; these assumptions would remain unchanged over the term of the insurance policy. Under the amended guidance, certain insurance commissions and expenses must be excluded from the expense assumption, which will result in an increase in the deferred profit liability on limited-payment products compared to current guidance. In conjunction with the adoption of the updated standard effective January 1, 2023, the Company will change 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 statement of earnings. This reclassification will have no impact on net earnings. The change in presentation will be made for all comparative periods presented. The Company has created a governance framework and a plan to support implementation of the updated standard. As part of its implementation plan, the Company continues to advance the modernization of its actuarial technology platform to enhance its modeling, data management, experience study and analytical capabilities, increase the end-to-end automation of key reporting and analytical processes and optimize its control framework. The Company has also put in place internal controls related to the new processes created as part of implementing the updated standard and will continue to refine and maturate these internal controls until the formal implementation in the first quarter of 2023. The Company continues testing its reporting and disclosure capabilities under the new ASU for post-Transition Date accounting periods. The Company currently has no products with market risk benefits. Impacts on Previously Reported Results Impacts from the adoption of ASU 2018-12 to the Company's previously reported results are expected to be as follows: Consolidated Statement of Earnings Year Ended December 31, 2021 (In millions) As Adoption As Revenues: Net earned premiums, principally supplemental health insurance (1) $ 17,647 $ (552) $ 17,095 Net investment income 3,818 0 3,818 Net investment gains (losses) 468 0 468 Other income (loss) 173 0 173 Total revenues 22,106 (552) 21,554 Benefits and expenses: Benefits and claims, excluding reserve remeasurement (1)(2) 10,576 47 10,623 Reserve remeasurement (gains) losses (3) 0 (147) (147) Total benefits and claims, net 10,576 (100) 10,476 Acquisition and operating expenses: Amortization of deferred policy acquisition costs (4) 1,170 (335) 835 Insurance commissions 1,256 0 1,256 Insurance and other expenses (5) 3,544 (3) 3,541 Interest expense 238 0 238 Total acquisition and operating expenses 6,208 (338) 5,870 Total benefits and expenses 16,784 (438) 16,346 Earnings before income taxes 5,322 (114) 5,208 Income taxes (6) 997 (20) 977 Net earnings $ 4,325 $ (94) $ 4,231 (1) Adjustment reflects a $489 increase in the deferred profit liability on limited-payment products under the updated standard combined with the reclassification of a $63 increase in deferred profit liability previously reported in benefits and claims and reclassified to net earned premiums in conjunction with adoption of the updated standard.
