Income Taxes	3 Months Ended

Income Tax Disclosure [Abstract]
Income Taxes	INCOME TAXES On December 22, 2017, President Trump signed into law the "Tax Cuts and Jobs Act" (the "Tax Act"). The Tax Act includes significant changes to the U.S. tax code that will affect our fiscal year ending September 29, 2018, and future periods, including, but not limited to, (1) reducing the corporate federal income tax rate from 35% to 21%, (2) bonus depreciation that will allow for full expensing of qualified property in the year placed in service, and (3) a general elimination of U.S. federal income taxes on dividends from foreign subsidiaries. Section 15 of the Internal Revenue Code (the "Code") stipulates that our fiscal year ending September 29, 2018, will have a blended corporate tax rate of 24.5%, which is based on the applicable tax rates before and after the Tax Act and the number of days in the year. Additionally, the Tax Act includes the repeal of the domestic production activity deduction, a new provision designed to tax global intangible low-taxed income ("GILTI"), a new provision which allows a deduction for foreign-derived intangible income ("FDII"), and a new provision which institutes a base erosion and anti-abuse tax ("BEAT"), beginning with our fiscal year 2019. We are still evaluating these new international provisions; however, we do not expect them to have a material impact to our financial statements. Changes in the Code from the Tax Act had a material impact on our financial statements in the first quarter of 2018. Under generally accepted accounting principles ("U.S. GAAP") specifically ASC Topic 740, Income Taxes, the tax effects of changes in tax laws must be recognized in the period in which the law is enacted, or December 22, 2017, for the Tax Act. ASC 740 also requires deferred tax assets and liabilities to be measured at the enacted tax rate expected to apply when temporary differences are to be realized or settled. Thus, at the date of enactment, the Company’s deferred taxes were re-measured based upon the new tax rates. The change in deferred taxes is recorded as an adjustment to our deferred tax provision. The staff of the U.S. Securities and Exchange Commission has recognized the complexity of reflecting the impacts of the Tax Act and issued guidance in Staff Accounting Bulletin 118 ("SAB 118"), which clarifies accounting for income taxes under ASC 740 if information is not yet available or complete and provides for up to a one year period in which to complete the required analyses and accounting (the "measurement period"). SAB 118 describes three scenarios (or "buckets") associated with a company’s status of accounting for income tax reform: (1) a company is complete with its accounting for certain effects of tax reform, (2) a company is able to determine a reasonable estimate for certain effects of tax reform and records that estimate as a provisional amount, or (3) a company is not able to determine a reasonable estimate and therefore continues to apply ASC 740, based on the provisions of the tax laws that were in effect immediately prior to the Tax Act being enacted. Our accounting for the Tax Act is incomplete. However, we were able to make reasonable estimates of certain effects and, therefore, recorded provisional adjustments as follows: Corporate Tax Rate Reduction: The Tax Act reduced the corporate tax rate from 35% to 21%, effective January 1, 2018. This results in a blended corporate tax rate of 24.5% in fiscal year 2018 and 21% thereafter. We analyzed our domestic deferred tax balances to estimate which of those balances are expected to reverse in fiscal 2018 or thereafter, and we re-measured the deferred taxes at 24.5% or 21% accordingly. In the three months ended December 30, 2017, we recorded a discrete net deferred income tax benefit of $994 million with a corresponding provisional reduction to our net deferred income tax liability. This estimate may change as we receive additional information about the timing of deferred income tax reversals. Transition Tax: The Tax Act requires a one-time Deemed Repatriation Transition Tax on previously untaxed net accumulated and current earnings and profits of our foreign subsidiaries. Based on our analysis of our foreign earnings and profits, net of deficits and foreign tax credits, we do not expect any transition tax to be due for the Company. Our accounting for the following element of the Tax Act is incomplete, and we were not yet able to make reasonable estimates of the effects. Therefore, no provisional adjustments were recorded. GILTI: The Tax Act creates a new requirement in tax years beginning after December 31, 2017, that certain income (i.e., GILTI) earned by controlled foreign corporations ("CFCs") must be included currently in the gross income of the CFCs’ U.S. shareholder. Because of the complexity of the new GILTI tax rules, we continue to evaluate this provision of the Tax Act and the application of ASC 740. Under U.S. GAAP, we are allowed to make an accounting policy choice of either (1) treating taxes due on future U.S. inclusions in taxable income related to GILTI as a current-period expense when incurred (the “period cost method”) or (2) factoring such amounts into a company’s measurement of its deferred taxes (the “deferred method”). Our selection of an accounting policy with respect to the new GILTI tax rules will depend, in part, on analyzing our global income to determine whether we expect to have future U.S. inclusions in taxable income related to GILTI and, if so, what the impact is expected to be. Since future U.S. inclusions in taxable income related to GILTI depends on not only our current ownership structure and estimated future results of global operations but also our intent and ability to modify such structure and/or our business, we are not yet able to reasonably estimate the effect of this provision of the Tax Act. Therefore, we have not made any adjustments related to potential GILTI tax in our financial statements and have not made a policy decision regarding whether to record deferred taxes on GILTI. The changes included in the Tax Act are broad and complex. The final transition impacts of the Tax Act may differ from the above estimates, due to, among other things, changes in interpretations of the Tax Act, any legislative action to address questions that arise because of the Tax Act, any changes in accounting standards for income taxes or related interpretations in response to the Tax Act, or any updates or changes to estimates the company has utilized to calculate the impacts. The effective tax rate was (93.8)% and 34.9% for the first quarter of fiscal 2018 and 2017, respectively. The remeasurement of deferred income taxes at newly enacted tax rates resulted in a $994 million income tax benefit, or a (118.1)% impact on the effective tax rate in the first quarter, and the newly enacted tax legislation resulted in a 24.5% statutory federal income tax rate for fiscal 2018. The effective tax rate for the first quarter 2018 also includes (2.3)% impact related to excess tax benefits associated with share-based payments to employees. Additionally, the effective tax rates for the first quarter of fiscal 2018 and fiscal 2017 were impacted by such items as the domestic production deduction and state income taxes. Unrecognized tax benefits were $305 million and $316 million at December 30, 2017, and September 30, 2017, respectively. We estimate that during the next twelve months it is reasonably possible that unrecognized tax benefits could decrease by as much as $12 million primarily due to expiration of statutes of limitations in various jurisdictions. As of September 30, 2017, we had accumulated undistributed earnings of foreign subsidiaries aggregating approximately $182 million. The Tax Act generally eliminates U.S. federal income taxes on dividends from foreign subsidiaries after December 31, 2017. As a result, our intention is that excess cash held by our foreign subsidiaries that is not subject to regulatory restrictions is expected to be repatriated net of applicable withholding taxes which are expected to be immaterial. The remainder of accumulated undistributed earnings are expected to be indefinitely reinvested outside of the United States.
