Summary of Significant Accounting Policies | 2. Summary of Significant Accounting Policies FUTURE APPLICATION OF ACCOUNTING STANDARDS Income Tax In December 2023, the Financial Accounting Standards Board (FASB) issued an accounting standard update to address improvements to income tax disclosures. The standard requires disaggregated information about a company’s effective tax rate reconciliation as well as information on income taxes paid. The standard is effective for public companies for annual periods beginning after December 15, 2024, which AIG plans to adopt on a prospective basis. The adoption of the standard will not have an impact on AIG’s consolidated results of operations and financial condition as this standard is related to the disclosures in the Notes to the Consolidated Financial Statements. Disaggregation of Income Statement Expenses On November 4, 2024, the FASB issued new guidance that is intended to improve disclosures regarding the nature of expenses included in the income statement. The standard will require companies to disaggregate certain expense captions into specified categories in disclosures within notes to the financial statements and provide qualitative descriptions for those that are not separately disclosed. The guidance is effective for annual reporting periods beginning after December 15, 2026, and interim reporting periods within annual reporting periods beginning after December 15, 2027. The requirements can be applied prospectively or retrospectively for prior periods presented when adopted. We are assessing the impact of the standard. Improvements to Internal-use Software In September 2025, the FASB issued targeted improvements to modernize the accounting for software development costs by aligning it with how software is developed today. The effective date for the standard is for annual periods beginning after December 15, 2027 and interim reporting periods within those fiscal years. Early adoption is permitted. The amendments can be applied either prospectively, retrospectively or utilizing a modified transition approach. We are assessing the impact of the standard.
