Income Tax Disclosure [Abstract] |
Income Taxes | INCOME TAXES Our effective tax rate was 27 percent and 28 percent for the three-month periods ended June 30, 2019 and 2018, respectively. The decrease in the rate was primarily due to a $3 million income tax expense resulting from enacted state and local tax law changes recognized in the three-month period ended June 30, 2018. Our effective tax rate was 26 percent and 25 percent for the six-month periods ended June 30, 2019 and 2018, respectively. The increase in the rate was primarily due to an additional $10 million income tax benefit on stock-based compensation recognized in the six-month period ended June 30, 2018.
