Income Tax Disclosure [Abstract]
Income Taxes	Income TaxesFor the three months ended June 30, 2020 and 2019, the provision for income taxes was $191 million and $234 million, respectively, representing effective tax rates of 16.6% and 20.9%, respectively. For the six months ended June 30, 2020 and 2019, the provision for income taxes was $415 million and $411 million, respectively, representing effective tax rates of 17.0% and 19.6%, respectively. The lower effective tax rate for the three and six months ended June 30, 2020 was primarily due to higher favorable permanent tax items, including interest income from lending to tax-exempt entities and income tax credits earned in the current year. 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.
