Income Tax Disclosure [Abstract]
Income Tax Disclosure	INCOME TAXES In December 2017, the U.S. enacted comprehensive tax legislation with the Tax Act, making broad and complex changes to U.S. tax law, including lowering the U.S. corporate income tax rate to 21%, transitioning to a modified territorial system, and providing for current expensing of certain qualifying capital expenditures. Also in December 2017, the SEC issued Staff Accounting Bulletin No. 118 ("SAB 118") to address the application of GAAP in situations when a registrant does not have the necessary information available, prepared, or analyzed (including computations) in reasonable detail to complete the accounting for certain income tax effects of the Tax Act. As of October 28, 2018, our accounting for the Tax Act was not finalized. As disclosed in our 2017 Form 10-K, however, we were able to reasonably estimate certain effects and, therefore, recorded a provisional charge of $400 million for the deemed repatriation of historical earnings of foreign subsidiaries, recorded a provisional benefit of $147 million for the remeasurement of deferred tax assets and liabilities, and estimated a $126 million benefit due to a lower U.S. statutory tax rate. During the third quarter of fiscal 2018, we recorded a benefit of $115 million as measurement-period adjustments related to (i) a benefit of $86 million for the deemed repatriation of historical earnings of foreign subsidiaries and (ii) a benefit of $29 million for deferred tax activity. These adjustments were made upon our further analysis of certain aspects of the Tax Act, refinement of our calculations, and the issuance of guidance by the U.S. Treasury. We have not made any additional measurement-period adjustments during the current quarter because we have not finalized our provisional adjustments. We will continue to analyze and refine our calculations related to the measurement of these balances as supplemental legislation, regulatory guidance, or evolving technical interpretations become available. Any adjustment to these amounts during the measurement period will be recorded to the provision for income taxes in the period in which the analysis is finalized. We expect to complete our accounting under SAB 118 in the fourth quarter of fiscal 2018. The Tax Act also creates a new requirement that certain income (i.e., global intangible low-taxed income or “GILTI”) earned by controlled foreign corporations (“CFCs”) must be included currently in the gross income of the CFCs’ U.S. shareholder. Due to the complexity of the new GILTI tax rules, we are not yet able to reasonably estimate the long-term effects of this provision. Therefore, we have not recorded any potential deferred tax effects related to GILTI in our consolidated financial statements and have not made a policy decision regarding whether to record deferred taxes on GILTI or use the period cost method. We have, however, included an estimate of the current GILTI impact in our estimated annual effective tax rate for fiscal 2018. Our income tax returns are routinely examined by domestic and foreign tax authorities. During the third quarter of fiscal 2018, we settled a transfer pricing issue between the U.S. and Mexican tax authorities. The resolution of this issue reduced our unrecognized tax benefits by $80 million. The net impact of the settlement resulted in an immaterial tax charge in the third quarter of fiscal 2018.

In December 2017, the U.S. enacted comprehensive tax legislation with the Tax Act, making broad and complex changes to U.S. tax law, including lowering the U.S. corporate income tax rate to 21%, transitioning to a modified territorial system, and providing for current expensing of certain qualifying capital expenditures.
