INCOME TAXES 

Our effective income tax rate was 19.5% for the three months ended June 30, 2019, as compared to 20.9% for the three months ended June 30, 2018, and 18.7% for the six months ended June 30, 2019, as compared to 18.0% for the six months ended June 30, 2018. The decrease in our effective tax rate for the three months ended June 30, 2019, as compared to the same period in the prior year, was primarily driven by statutory earnings mix, with relatively higher statutory earnings subject to lower international tax rates than domestic tax rates. The increase in our effective tax rate for the six months ended June 30, 2019, as compared to the same period in the prior year, was primarily driven by lower tax benefits from share-based compensation, partially offset by a nonrecurring item recorded in the three months ended March 31, 2018, that resulted from the 2017 Tax Cut and Jobs Act, as well as statutory earnings mix, with relatively higher statutory earnings subject to lower international tax rates than domestic tax rates.

The effective tax rate for the three and six months ended June 30, 2019, differed from the U.S. statutory tax rate of 21% primarily due to tax benefits from share-based compensation.
