INCOME TAXES

Our effective income tax rate was 22.3% and 14.5% for the three months ended March 31, 2022 and 2021, respectively. Our effective income tax rate can differ from the 21% U.S. federal statutory rate due to a number of factors, including foreign rate differences, tax incentives, increases or decreases in valuation allowances and liabilities for uncertain tax positions and excess tax benefits on stock compensation awards.

For the three months ended March 31, 2022, the difference between our effective income tax rate and the U.S. federal statutory rate was primarily attributable to discrete tax matters in various foreign jurisdictions, of which none are individually material, and an increase in our liabilities for uncertain tax positions, partially offset by excess tax benefits on stock compensation awards and a favorable geographic earnings mix.

For the three months ended March 31, 2021, the difference between our effective income tax rate and the U.S. federal statutory rate was primarily attributable to decreases in accrued withholding taxes in several foreign jurisdictions and a favorable geographic earnings mix.
