Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The effective income tax rates were 35.5% and 45.2% for the twelve weeks ended September 12, 2017 and September 6, 2016, respectively. The provision for income taxes consisted of income tax expense of $2.8 million and $4.1 million for the twelve weeks ended September 12, 2017 and September 6, 2016, respectively. The effective income tax rates were 37.9% and 42.5% for the thirty-six weeks ended September 12, 2017 and September 6, 2016, respectively. The provision for income taxes consisted of income tax expense of $9.0 million and $9.5 million for the thirty-six weeks ended September 12, 2017 and September 6, 2016, respectively. The income tax expense for the twelve weeks ended September 12, 2017 is driven by the estimated effective income tax rate of 35.5% which primarily consists of statutory federal and state tax rates based on apportioned income, reduced by higher stock compensation expense deductible for tax related to the June 30, 2017 vesting of certain restricted stock awards as compared to the cumulative amount recorded as stock-based compensation expense, as well as federal targeted job credits. The income tax expense for the twelve weeks ended September 6, 2016 is driven by the estimated effective income tax rate of 45.2% which primarily consists of statutory federal and state tax rates based on apportioned income, as well as providing for deferred tax liabilities for the excess of the amount for financial reporting over the tax basis of an investment in a domestic subsidiary. In addition, the effective tax rate is also driven by transaction-related costs incurred in connection with the warrant tender offer which are not deductible for taxes as well as lower stock compensation expense deductible for tax related to the June 30, 2016 vesting of certain restricted stock awards as compared to the cumulative amount recorded as stock-based compensation expense, partially offset by federal targeted job credits. The income tax expense for the thirty-six weeks ended September 12, 2017 is driven by the estimated effective income tax rate of 37.9% which primarily consists of statutory federal and state tax rates based on apportioned income, reduced by higher stock compensation expense deductible for tax related to the June 30, 2017 vesting of certain restricted stock awards as compared to the cumulative amount recorded as stock-based compensation expense, as well as federal targeted job credits. The income tax expense for the thirty-six weeks ended September 6, 2016 is driven by the estimated effective income tax rate of 42.5% which primarily consists of statutory federal and state tax rates based on apportioned income, as well as providing for deferred tax liabilities for the excess of the amount for financial reporting over the tax basis of an investment in a domestic subsidiary. In addition, the effective tax rate is also driven by transaction-related costs incurred in connection with the warrant tender offer which are not deductible for taxes as well as lower stock compensation expense deductible for tax related to the June 30, 2016 vesting of certain restricted stock awards as compared to the cumulative amount recorded as stock-based compensation expense, partially offset by federal targeted job credits. Management believes it is more likely than not that all deferred tax assets will be realized and therefore no valuation allowance as of September 12, 2017 and January 3, 2017 is required.
