Accounting Policies [Abstract]
Basis of Accounting, Policy [Policy Text Block]	Basis of presentation — Our consolidated financial statements are prepared in accordance with accounting principles generally accepted in the United States (GAAP) for interim financial information. These statements are unaudited, but in the opinion of management include all adjustments (consisting only of normal recurring adjustments) necessary for a fair statement of the results for the interim periods. The results reported in these consolidated financial statements should not necessarily be taken as indicative of results that may be expected for the entire year. The financial information included herein should be read in conjunction with the consolidated financial statements in Item 8 of our Annual Report on Form 10-K for the year ended December 31, 2021 (the 2021 Form 10-K). Certain prior year amounts have been reclassified to conform to the current presentation. During the first quarter of 2022, we identified an error related to certain intercompany inventory transfers that were not appropriately eliminated and recorded an adjustment of $8 to cost of sales. A portion of this adjustment relates to prior periods. We concluded that the correction of this error is not material to the financial statements for the quarter ended March 31, 2022 or any prior periods.
