Income Tax Disclosure [Abstract]
Income Taxes	Note 9 – Income Taxes The effective income tax rate was 11.9% and 38.2% for the 12 weeks ended October 6, 2018 and October 7, 2017, respectively. For the 40 weeks ended October 6, 2018 and October 7, 2017, the effective income tax rate was 20.6% and 39.4%, respectively. The difference from the federal statutory rate of 21% in 2018 was primarily due to the lapse of the statute of limitations for an uncertain tax position, the Federal rate change effect on the finalization of deferred taxes for 2017 and tax credits, partially offset by state income taxes. The difference from the federal statutory rate of 35% for 2017 was primarily due to state taxes, stock-based compensation and federal tax credits. On December 22, 2017, the U.S. government enacted comprehensive tax legislation commonly referred to as the Tax Cuts and Jobs Act (the “Tax Act”). The Tax Act made broad and complex changes to the U.S. tax code, including, but not limited to reducing the U.S. federal corporate tax rate from 35 percent to 21 percent, effective January 1, 2018. In connection with initial analysis of the impact of the Tax Act, the Company recorded a provisional discrete income tax benefit of $26.0 million in the period ended December 30, 2017 associated with the re-measurement of deferred tax assets and liabilities as a result of the reduction in the U.S. federal corporate tax rate. During the 12 weeks ended October 6, 2018, the Company completed its accounting for the income tax effects of certain elements of the Tax Act, resulting in an income tax benefit of $0.5 million.
