Income Taxes INCOME TAXES 
Our effective income tax rate was 14.9% for the three months ended March 31, 2021, as compared to 18.2% for the three months ended March 31, 2020, The decrease in our effective tax rate for the three months ended March 31, 2021, as compared to the same period in the prior year, was primarily driven by higher tax benefits from share-based compensation and regional earnings mix.

The effective tax rate for the three months ended March 31, 2021, differed from the U.S. statutory tax rate of 21% primarily due to tax benefits from share-based compensation.
