Income Tax Disclosure [Abstract]
Income Taxes	INCOME TAXES Our effective tax rate was 27 percent for both of the three-month periods ended September 30, 2019 and 2018. Our effective tax rate was 26 percent and 25 percent for the nine-month periods ended September 30, 2019 and 2018, respectively. The increase in the rate was primarily due to an additional $9 million income tax benefit on stock-based compensation recognized in the nine-month period ended September 30, 2018.
