Income Tax Disclosure [Abstract]
Income Taxes	NOTE 3 — INCOME TAXES Our provision for income taxes for the quarters ended September 30, 2020 and 2019 was $209 million and $215 million, respectively, and the effective tax rates were 23.8% and 26.0%, respectively. Our provision for income taxes for the nine months ended September 30, 2020 and 2019 was $665 million and $765 million, respectively, and the effective tax rates were 22.2% and 23.9%, respectively. Our provision for income taxes included tax benefits related to the settlement of employee equity awards of $59 million and $56 million for the nine months ended September 30, 2020 and 2019, respectively. Our liability for unrecognized tax benefits was $523 million, including accrued interest of $74 million, as of September 30, 2020 ($550 million and $62 million, respectively, as of December 31, 2019). Unrecognized tax benefits of $167 million ($160 million as of December 31, 2019) would affect the effective rate, if recognized. The Internal Revenue Service was conducting an examination of the Company’s 2016, 2017 and 2018 federal income tax returns at September 30, 2020. We are also subject to examination by state and foreign taxing authorities. Depending on the resolution of any federal, state and foreign tax disputes, the completion of examinations by federal, state or foreign taxing authorities, or the expiration of statutes of limitation for specific taxing jurisdictions, we believe it is reasonably possible that our liability for unrecognized tax benefits may significantly increase or decrease within the next 12 months. However, we are currently unable to estimate the range of any possible change.
