Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes In accordance with ASC 740, Income Taxes (“ASC 740”), each interim period is considered integral to the annual period and tax expense is measured using an estimated annual effective tax rate. An entity is required to record income tax expense each quarter based on its annual effective tax rate estimated for the full fiscal year and use that rate to provide for income taxes on a current year-to-date basis, adjusted for discrete taxable events that occur during the interim period. The Company’s effective tax rate for the thirteen weeks ended November 24, 2018 was 26.2% compared to 35.5% for the corresponding period in the prior year. The reduction in the effective tax rates in the thirteen weeks ended November 24, 2018 as compared to the corresponding period in the prior year was due primarily to the impact of Tax Cuts and Jobs Act (the “Act”) enacted on December 22, 2017. As a result of the Act, U.S. corporations are subject to lower income tax rates, which also caused the Company to remeasure its U.S. net deferred tax liabilities at the lower rates. Also because of this Act, the Company is subject to a one-time transition tax for the deemed repatriation of its foreign earnings. U.S. Tax Reform The Act, among other matters, reduced the U.S. federal corporate income tax rate from 35% to 21%, required companies to pay a one-time transition tax on earnings of certain foreign subsidiaries that were previously tax deferred, and created new taxes on certain foreign sourced earnings. As of November 24, 2018, the Company had not completed its accounting for the tax effects of enactment of the Act and is still analyzing certain aspects of the Act and refining its calculations, which could potentially affect the measurement of these balances or potentially give rise to new deferred tax amounts. On December 22, 2017, the SEC issued Staff Accounting Bulletin No. 118, Income Tax Accounting Implications of the Act (“SAB 118”) directing SEC registrants to consider the impact of the Act as “provisional” when they do not have the necessary information available, prepared or analyzed (including computations) in reasonable detail to complete their accounting for the change in tax law. In accordance with SAB 118, the amounts recorded related to accounting for the Act represent the Company’s best estimate based on its interpretation of the Act as the Company is still accumulating data to finalize the underlying calculations, or in certain cases, the U.S. Treasury is expected to issue further guidance on the application of certain provisions of the Act. In addition, the Company also used assumptions and estimates that may change as a result of future guidance and interpretation from the Internal Revenue Service, the SEC, the FASB and various other taxing jurisdictions. In particular, the Company anticipates that the U.S. state jurisdictions will continue to determine and announce their conformity or decoupling from the Act, either in its entirety or with respect to specific provisions. All of these potential legislative and interpretive actions could result in adjustments to the Company's provisional estimates when the accounting for the income tax effects of the Act is completed. Uncertain tax positions The Company recognizes interest and penalties related to uncertain tax positions as a component of income tax expense which is consistent with the recognition of these items in prior reporting periods. During the thirteen weeks ended November 24, 2018, there were no material changes in the amount of unrecognized tax benefits or the amount accrued for interest and penalties. All U.S. and Canadian federal income tax statutes have lapsed for filings up to and including fiscal years 2013 and 2010, respectively. With a few exceptions, the Company is no longer subject to state and local income tax examinations for periods prior to fiscal 2014. The Company is not aware of any tax positions for which it is reasonably possible that the total amounts of unrecognized tax benefits will change significantly in the next 12 months.
