Income Taxes INCOME TAXES 
Our effective income tax rate was 10.8% for the three months ended September 30, 2020, as compared to 18.0% for the three months ended September 30, 2019, and 16.0% for the nine months ended September 30, 2020, as compared to 18.5% for the nine months ended September 30, 2019. The decrease in our effective tax rate for the three and nine months ended September 30, 2020, as compared to the same period in the prior year, was primarily driven by higher tax benefits from share-based compensation.

The effective tax rate for the three and nine months ended September 30, 2020, differed from the U.S. statutory tax rate of 21% primarily due to tax benefits from share-based compensation.
