Income Taxes	9 Months Ended

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes Our effective tax rate was 20% and 21% for the nine months ended September 30, 2019 and 2018, respectively, and 16% for both the three months ended September 30, 2019 and 2018. The effective tax rate for the nine months ended September 30, 2019 is lower than the effective tax rate for the same period in 2018 primarily due to changes in estimates of certain international tax provisions enacted as part of the U.S. Federal Tax Cuts and Jobs Act, or TCJA, and reductions of income tax reserves resulting from the expiration of certain statutes of limitation.
