Income Tax Disclosure [Abstract]
Income Taxes	Note N – Income Taxes The Company’s effective income tax rate on pretax income for the twelve weeks ended November 17, 2018, was 21.7% compared to 34.6% for the prior year period. The decrease in the tax rate was primarily due to the reduction in the Company’s Federal statutory tax rate from 35% to 21% upon enactment of Tax Reform, which resulted in a tax benefit of $52.6 million in addition to $9.0 million excess tax benefits from option exercises versus the prior year period. The Company’s effective tax rate for the twelve weeks ended November 17, 2018 of 21.7% was slightly higher than the U.S. statutory federal rate of 21% primarily due to state income taxes offset by $11.2 million of tax benefits associated with stock option accounting, compared to $2.2 million in the prior year period. The SEC staff issued Staff Accounting Bulletin No. 118 (“SAB 118”) to address the application of GAAP in situations where 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 Tax Reform. To the extent that a company’s accounting for certain income tax effects of Tax Reform is incomplete but it is able to determine a reasonable estimate, it must record a provisional estimate in the financial statements. If a company cannot determine a provisional estimate to be included in the financial statements, it should continue to apply ASC 740 on the basis of the provisions of the tax laws that were in effect immediately before the enactment of Tax Reform. The ultimate impact may differ from provisional amounts recorded, possibly materially, due to, among other things, additional analysis, changes in interpretations and assumptions the Company has made, and additional regulatory guidance that may be issued.
