4.     Income Taxes

The Company’s quarterly provision for income taxes is measured using an annual effective tax rate, adjusted for discrete items within the period presented. To determine the annual effective tax rate, the Company estimates both the total income (loss) before income taxes for the full year and the jurisdictions in which that income (loss) is subject to tax. The actual effective tax rate for the full year may differ from these estimates if income (loss) before income taxes is greater than or less than what was estimated or if the allocation of income (loss) to jurisdictions in which it is taxed is different from the estimated allocations.

The effective tax rate for the three months ended  March 31, 2024 and 2023 was 20.2% and 23.1%, respectively. Differences between the Company’s effective income tax rate and the U.S. federal statutory rate are primarily the impact of research and development credits, permanent differences, and state taxes.
