Income Tax Disclosure [Abstract]
Income Taxes	INCOME TAXES Our effective tax rate was a benefit of 63.5 percent for the 2020 first quarter compared to a provision of 13.2 percent for the 2019 first quarter. The decrease in our effective tax rate was primarily due to a more favorable impact from stock based compensation as a percentage of lower pre-tax book income. We paid cash for income taxes, net of refunds, of $59 million in the 2020 first quarter and $64 million in the 2019 first quarter.
