Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company’s interim income tax provisions are based on the effective income tax rate expected to be applicable for the full fiscal year, adjusted for specific items that are required to be recognized in the period in which they occur. Deferred tax assets and liabilities are based on the enacted tax rate that will apply in future periods when such assets and liabilities are expected to be settled or realized. The Tax Cuts and Jobs Act of 2017 (“Tax Reform”) was enacted in December 2017 and includes significant changes to U.S. income tax law. Tax Reform, among other things, reduced the U.S. federal corporate income tax rate from 35 percent to 21 percent. As a result, the Company’s net deferred tax liabilities as of January 27, 2018 were remeasured to reflect the reduced rate under Tax Reform. The Company’s effective income tax rate of 27.5% and 36.7% for the nine months ended October 27, 2018 and October 28, 2017, respectively, differs from the applicable U.S. federal corporate income tax rate for each respective period primarily as the result of non-deductible and non-taxable items, tax credits recognized in relation to pre-tax results, and certain impacts from the vesting and exercise of share-based awards. The Company’s current interpretations of the provisions of Tax Reform could differ from future interpretations and guidance from the U.S. Treasury Department, the IRS and other regulatory agencies, including state taxing authorities in jurisdictions where the Company operates. Any future adjustments resulting from these factors would impact the Company’s provision for income taxes and effective tax rate in the period in which they are made.
