Organization, Consolidation and Presentation of Financial Statements [Abstract] |
Basis of Presentation | 1. Basis of Presentation American International Group, Inc. is a leading global insurance organization. AIG provides insurance solutions that help businesses and individuals in over 200 countries and jurisdictions protect their assets and manage risks through AIG operations, licenses and authorizations as well as network partners. Unless the context indicates otherwise, the terms “AIG,” “we,” “us,” “our” or "the Company" mean American International Group, Inc. and its consolidated subsidiaries, and the term “AIG Parent” means American International Group, Inc. and not any of its consolidated subsidiaries. These unaudited Condensed Consolidated Financial Statements do not include all disclosures that are normally included in annual financial statements prepared in accordance with accounting principles generally accepted in the United States (GAAP) and should be read in conjunction with the audited Consolidated Financial Statements and the related notes included in our Annual Report on Form 10-K for the year ended December 31, 2024 (the 2024 Annual Report). The condensed consolidated financial information as of December 31, 2024 included herein has been derived from the audited Consolidated Financial Statements in the 2024 Annual Report. In the opinion of management, these Condensed Consolidated Financial Statements contain normal recurring adjustments, including eliminations of material intercompany accounts and transactions, necessary for a fair statement of the results presented herein. Results of operations for the nine months ended September 30, 2025 are not necessarily indicative of the results that may be expected for the year ending December 31, 2025. We evaluated the need to recognize or disclose events that occurred subsequent to September 30, 2025 and prior to the issuance of these Condensed Consolidated Financial Statements. USE OF ESTIMATES The preparation of financial statements in accordance with U.S. GAAP requires the application of accounting policies that often involve a significant degree of judgment. Accounting policies that we believe are most dependent on the application of estimates and assumptions are considered our critical accounting estimates and are related to the determination of: •loss reserves; •reinsurance assets, including the allowance for credit losses and disputes; •allowance for credit losses on certain investments, primarily on loans and available for sale fixed maturity securities; •fair value measurements of certain financial assets and financial liabilities; and •income taxes, in particular the recoverability of our deferred tax asset and establishment of provisions for uncertain tax positions. These accounting estimates require the use of assumptions about matters, some of which are highly uncertain at the time of estimation. To the extent actual experience differs from the assumptions used, our consolidated financial condition, results of operations and cash flows could be materially affected.
