Income taxes Income taxes
The estimated effective annual tax rate as of March 31, 2025 and 2024 for the years ended December 31, 2025 and 2024, excluding the impact of discrete adjustments, was 27% and 19%, respectively. The effective tax rate for the three months ended March 31, 2025 and 2024 was 27% and 26%, respectively. The increase in the estimated effective annual tax rate and the effective quarterly tax rate is primarily due to an increase in estimated profit combined with a change in jurisdictional mix of income and losses.
The Company establishes valuation allowances for deferred income tax assets in accordance with U.S. GAAP, which provides that such valuation allowances shall be established unless realization of the income tax benefits is more likely than not. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible. At each reporting period, the Company considers the scheduled reversal of deferred tax liabilities and assets, available taxes in carryback periods, tax planning strategies and projected future taxable income in making this assessment.
