Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes On May 19, 2019, a public referendum held in Switzerland passed the Federal Act on Tax Reform and AHV Financing (TRAF), effective January 1, 2020. The enactment of certain provisions of the TRAF resulted in adjustments to our deferred taxes. During 2020, we recorded a net tax benefit of $72 million related to the adoption of the TRAF in the Swiss Canton of Bern. There were no income tax adjustments related to the TRAF recorded in either of the 12 weeks ended March 20, 2021 or March 21, 2020. While the accounting for the impacts of the TRAF are deemed to be complete, further adjustments to our financial statements and related disclosures could be made in future quarters, including in connection with final tax return filings. For further information and discussion of the TRAF, refer to Note 5 to our consolidated financial statements in our 2020 Form 10-K.
