Income Tax Disclosure [Abstract]
INCOME TAXES	INCOME TAXES On December 22, 2017, the Tax Act was enacted in the U.S. The Tax Act introduced many changes, including lowering the U.S. corporate tax rate from 35% to 21%, changes in incentives, provisions to prevent U.S. base erosion and significant changes in the taxation of international income, and provisions which allow for the repatriation of foreign earnings without U.S. tax. By operation of tax law, the Company will apply a blended U.S. statutory federal income tax rate of 22.4% for fiscal year 2018 based on the pro rata number of days in the fiscal year before and after the effective date of the Tax Act. The enactment of the Tax Act resulted in a provisional charge of $137 million to tax expense in the first half of fiscal year 2018. This charge was comprised of a $99 million re-measurement of the Company's deferred tax assets and liabilities based on the lower rates at which they are expected to reverse in the future as well as a $38 million one-time U.S. transition tax on undistributed foreign earnings. The provisions in the Tax Act are complex and broad. All components of the provisional charge of $137 million are based on the Company’s estimates as of May 27, 2018. Specifically, the transition tax and the re-measurement of deferred tax balances are provisional and have been calculated based on existing tax law and the best information available as of May 27, 2018. The final impact of U.S. tax reform may differ, possibly materially, due to factors such as changes in interpretations of the Tax Act, legislative action to address uncertainties that arise because of the Tax Act, changes to estimates the Company has utilized to calculate the provisional impacts, and additional guidance that may be issued by the U.S. government, among other items. As these various factors are finalized, any change will be recorded as an adjustment to the provision for income taxes in the period the amounts are determined during a measurement period granted by the Securities and Exchange Commission of up to one year after the enactment date of the Tax Act to finalize the accounting of the related income tax impacts, not to exceed 12 months from the date of enactment of the Tax Act. In addition, the Company is still evaluating the Global Intangible Low Tax Income ("GILTI") provisions of the Tax Act and their impact, if any, on the consolidated financial statements beginning fiscal year 2019, including whether the Company adopts an accounting policy to treat such taxes as a current-period expense when incurred or whether such amounts should be factored into the Company's measurement of deferred taxes. As a result, the Company has not included an estimate of the tax expense related to this item as of May 27, 2018. The effective income tax benefit rate of 1.7% for the three months ended May 27, 2018 was driven by a 17.5% discrete tax benefit from release of reserves for uncertain tax positions due to finalization of a foreign audit in the second quarter of 2018. The effective income tax rate was 74.0% for the six months ended May 27, 2018, compared to 16.0% for the same period ended May 28, 2017. The increase in the effective tax rate in 2018 as compared to 2017 was driven by a 61% one-time tax charge related to the impact of the U.S. tax reform described above, offset by a 5.9% discrete tax benefit from release of reserves for uncertain tax positions due to finalization of a foreign audit in the second quarter of 2018.
