| Income Taxes | 5. Income Taxes Our provision for income taxes varied from the tax computed at the U.S. federal statutory income tax rate for the periods presented primarily due to the Foreign Derived Intangible Income deduction, state taxes, employee compensation limitation, the tax effects of stock-based compensation, and the U.S. research and development tax credit. Our effective tax rate was 23.8% and 23.6% for the three months ended June 30, 2025 and 2024, respectively, and 21.3% and 16.6% for the six months ended June 30, 2025 and 2024, respectively. The increase in the effective tax rate for the three months ended June 30, 2025 is due to a decrease of excess tax benefits on restricted stock awards that vested during the quarter. The increase in the effective tax rate for the six months ended June 30, 2025 is also due to a decrease of excess tax benefits on restricted stock awards that vested during the period. We apply the provisions for income taxes related to, among other things, accounting for uncertain tax positions and disclosure requirements in accordance with Accounting Standards Classification (ASC) 740, Income Taxes. For the three months ended June 30, 2025, there were no material changes to our uncertain tax positions. We conduct business globally and, as a result, file income tax returns in the U.S. federal jurisdiction and various state and foreign jurisdictions. In the normal course of business, Manhattan is subject to examination by taxing authorities throughout the world. We are no longer subject to U.S. federal, substantially all state and local income tax examinations and substantially all non-U.S. income tax examinations for years before 2010. |
