Retirement Benefits [Abstract]
Pension and Other Postretirement Benefits Disclosure [Text Block]	We maintain certain defined contribution retirement plans (the "Plans"), which qualify under Section 401(k) of the Internal Revenue Code. Generally, the Plans allow our U.S. associates to make salary contributions to the Plans, subject to annual limitations determined by the Internal Revenue Service. The Plans provide for certain discretionary matches on behalf of the participants for which we recognized expenses of $61 million, $59 million and $41 million in 2020, 2019 and 2018, respectively.
