Our effective tax rate was 26% percent for the three months ended March 31, 2024, compared to 9% for the three months ended March 31, 2023. The increase in our effective tax rate is primarily due to the impact of releasing the valuation allowance on our U.S. deferred tax assets in the fourth quarter of 2023 and changes in the mix of our jurisdictional earnings.
Our effective tax rates for the first three months of 2024 and 2023 differed from the U.S. federal statutory rate of 21% primarily due to the mix of our jurisdictional earnings subject to different tax rates, impact of valuation allowances on our deferred tax assets, as well as benefits from our U.S. tax credits and the Inflation Reduction Act of 2022 (“IRA”) manufacturing credits.
We are subject to tax examinations in the U.S. federal, state, and foreign jurisdictions. Given the uncertainty in timing and outcome of our tax examinations, an estimate of the range of the reasonably possible change in gross unrecognized tax benefits within twelve months cannot be made at this time.
