Our effective income tax rate was 18.9% and 36.4% in the first quarters of 2021 and 2020, respectively. This decrease is primarily attributed to the change in the mix of earnings by jurisdiction and the establishment of valuation allowance on certain tax credits in the first quarter of 2020. The first quarter 2021 tax rate was lower than the U.S. statutory federal tax rate primarily due to foreign earnings that are taxed at lower rates and tax benefits recorded upon vesting of restricted stock units. The first quarter 2020 tax rate was higher than the U.S. statutory federal tax rate primarily due to the establishment of valuation allowances on certain tax credits and a one-time tax expense resulting from a company restructuring.
