Income Tax Disclosure [Abstract]
Income Taxes	INCOME TAXES Our effective tax rate was 27 percent and 26 percent for the three-month periods ended June 30, 2020 and 2019, respectively. The increase in the tax rate was primarily due to an additional $1 million income tax benefit on stock-based compensation recognized in the second quarter of 2019 and the recording of a valuation allowance against deferred tax assets in certain jurisdictions in the second quarter of 2020. Our effective tax rate was 24 percent and 25 percent for the six-month periods ended June 30, 2020 and 2019, respectively. The decrease in the tax rate was primarily due to an additional $1 million income tax benefit on stock-based compensation and an additional $3 million state income tax benefit from a reduction in the liability for uncertain tax positions resulting from the expiration of statutes of limitation recognized in the first half of 2020.
