Subsequent Events [Abstract]
Subsequent Events	Subsequent EventAs of November 1, 2020, we had a committed revolving credit facility totaling $1,850 scheduled to mature on December 9, 2021. The facility remained unused at November 1, 2020, except for $1 of standby letters of credit that we issued under it. On November 2, 2020, we replaced the current facility with a new $1,850 committed revolving facility that matures on November 2, 2023. The new facility contains customary covenants, including a financial covenant with respect to a minimum consolidated interest coverage ratio of consolidated adjusted EBITDA to consolidated interest expense (as each is defined in the credit facility) of not less than 3.25:1.00, measured quarterly, and customary events of default for credit facilities of this type. Loans under this facility will bear interest at the rates specified in the facility, which vary based on the type of loan and certain other customary conditions. The facility supports our commercial paper program and other general corporate purposes.
