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 Japan and the United States (U.S.). The Company's insurance business is marketed and administered through Aflac Life Insurance Japan Ltd. (ALIJ) in Japan and through American Family Life Assurance Company of Columbus (Aflac), American Family Life Assurance Company of New York (Aflac New York), Continental American Insurance Company (CAIC), Tier One Insurance Company (TOIC) and Aflac Benefits Solutions, Inc. (ABS) in the U.S. The Company’s operations consist of two reportable business segments: Aflac Japan, which includes ALIJ, and Aflac U.S., which includes Aflac, Aflac New York, CAIC, TOIC, and ABS. Aflac New York is a wholly owned subsidiary of Aflac. Most of the Aflac U.S. policies are individually underwritten and marketed through independent agents. With the exception of dental and vision products administered by ABS, and certain group life insurance products, Aflac U.S. markets and administers group products through CAIC, branded as Aflac Group Insurance. Additionally, Aflac U.S. markets its consumer markets products through TOIC. The Company's insurance operations in the U.S. and Japan service the two markets for the Company's insurance business. The Parent Company, other operating business units that are not individually reportable, reinsurance activities, including internal reinsurance activity with Aflac Re Bermuda Ltd.(Aflac Re), and other business activities not included in Aflac Japan or Aflac U.S., as well as intercompany eliminations, are included in Corporate and other. Basis of Presentation The Company prepares its financial statements in accordance with U.S. generally accepted accounting principles (U.S. GAAP). These principles are established primarily by the Financial Accounting Standards Board (FASB). In these Notes to the Consolidated Financial Statements, references to U.S. GAAP issued by the FASB are derived from the FASB Accounting Standards Codification TM (ASC). The preparation of financial statements in conformity with U.S. GAAP requires the Company to make estimates based on currently available information when recording transactions resulting from business operations. The most significant items on the Company's balance sheet that involve a greater degree of accounting estimates and actuarial determinations subject to changes in the future are the valuation of investments and derivatives, deferred policy acquisition costs (DAC), liabilities for future policy benefits and income taxes. These accounting estimates and actuarial determinations are sensitive to market conditions, investment yields, interest rates, mortality, morbidity, commission and other acquisition expenses and terminations by policyholders. As additional information becomes available, or actual amounts are determinable, the recorded estimates are revised and reflected in the consolidated financial statements. Although some variability is inherent in these estimates, the Company believes the amounts provided are reasonable and reflective of the best estimates of management. The 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 March 31, 2025 and December 31, 2024, and the consolidated statements of earnings, comprehensive income (loss), shareholders' equity and cash flows for the three-month periods ended March 31, 2025 and 2024. 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, 2024 (2024 Annual Report).
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.
