Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes For the second quarter of 2021, the Company calculated the provision for income taxes on the current estimate of the annual effective tax rate and adjusted as necessary for quarterly events. Due to the impacts of the COVID-19 pandemic, the income tax expense for the second quarter of 2020 was computed on a year-to-date effective tax rate. For the second quarter of 2021, the Company’s effective tax rate was 25.1% compared to 17.7% in the second quarter of 2020. The second quarter of 2021 rate was lower than the Company's combined estimated federal and state statutory rate primarily due to the recognition of excess tax benefits recorded through the Consolidated Statements of Income on share-based awards that vested in the quarter. In the second quarter of 2020, the Company recognized a benefit for income taxes of $11 million on a loss before income taxes of $60 million. The second quarter of 2020 rate was lower than the Company's combined federal and state statutory rate primarily due to losses related to certain foreign subsidiaries, which generated no tax benefit, offset by changes in tax legislation included in the CARES Act, which resulted in a $21 million tax benefit. For year-to-date 2021, the Company's effective tax rate was 23.6% compared to 26.7% year-to-date 2020. The year-to-date 2021 rate was lower than the Company's combined estimated federal and state statutory rate primarily due to the recognition of excess tax benefits recorded through the Consolidated Statements of Income on share-based awards that vested year-to-date. The year-to-date 2020 rate was generally consistent with the Company's combined estimated federal and state statutory rate due to the resolution of certain tax matters, which resulted in a $50 million tax benefit and changes in tax legislation included in the CARES Act, which resulted in a $21 million tax benefit, offset by losses related to certain foreign subsidiaries, which generate no tax benefit. Income taxes paid were $320 million and $13 million for the second quarter of 2021 and 2020, respectively. Income taxes paid were $330 million and $22 million for year-to-date 2021 and 2020, respectively.
