Income Tax Disclosure [Abstract]
Income Taxes	Income TaxesFor the three months ended June 30, 2022 and 2021, the provision for income taxes was $372 million and $415 million, respectively, representing effective tax rates of 19.5% and 20.0%, respectively. For the six months ended June 30, 2022 and 2021, the provision for income taxes was $702 million and $766 million, respectively, representing effective tax rates of 19.2% and 19.7%, respectively. The lower effective tax rate for the three months ended June 30, 2022 was primarily driven by lower pre-tax income. The lower effective tax rate for the six months ended June 30, 2022 was primarily driven by changes in discrete taxes. The Company calculated the provision for income taxes by applying the estimated annual effective tax rate to year-to-date pre-tax income and adjusting for discrete items that occurred during the period.
