Income Tax Disclosure [Abstract] |
Income taxes | Note 19. Income taxes Our consolidated effective income tax rate in the first quarter of 2025 was 9.2% compared to 18.3% in the first quarter of 2024. Our effective income tax rate normally reflects recurring benefits from dividends-received deductions applicable to investments in certain equity securities and production tax credits related to wind-powered electricity generation placed in service in the U.S. Our periodic effective income tax rate will also vary due to the changes in mix of pre-tax earnings, including realized and unrealized investment gains or losses with respect to our investments in equity securities, the amount of non-deductible goodwill impairment charges and other expenses and the underlying income tax rates applicable in the various taxing jurisdictions. The Organization for Economic Co-operation and Development issued Pillar Two model rules introducing a global minimum tax of 15%. While the U.S. has not adopted the Pillar Two rules, various countries are enacting legislation to adopt the rules. We do not currently have material operations in jurisdictions with income tax rates lower than the Pillar Two minimum tax rate, and we do not currently expect these rules will materially increase our global tax costs. There remains uncertainty as to the final Pillar Two rules.
