Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company accounts for income taxes under the asset and liability method. This approach requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of temporary differences between the carrying amounts and the tax bases of assets and liabilities. The Company's effective income tax rate differs from the statutory rate for the tax jurisdictions where it operates primarily as the result of the impact of non-deductible and non-taxable items and tax credits recognized in relation to pre-tax results. Measurement of the Company's tax position is based on the applicable statutes, federal and state case law, and its interpretations of tax regulations. The Company is subject to federal income taxes in the United States, the income taxes of multiple state jurisdictions and in Canada. There were immaterial amounts of pre-tax income related to Canadian operations for the three and six months ended January 23, 2016 and January 24, 2015. With few exceptions, the Company is no longer subject to U.S. federal, state and local, or Canadian income tax examinations for fiscal years ended 2011 and prior. The Company believes its provision for income taxes is adequate; however, any assessment would affect the Company's results of operations and cash flows. Income tax receivable was $29.3 million and $2.1 million as of January 23, 2016 and July 25, 2015, respectively. The $2.1 million income tax receivable as of July 25, 2015 was included in other current assets. The increase in income tax receivable and related increase in deferred tax liabilities, net non-current, was primarily related to the extension of bonus depreciation pursuant to the Protecting Americans from Tax Hikes Act of December 2015. Income tax payable was $0.3 million and $8.9 million as of January 23, 2016 and July 25, 2015, respectively, and was included in other accrued liabilities. As of both January 23, 2016 and July 25, 2015, the Company had total unrecognized tax benefits of $2.3 million, resulting from uncertain tax positions. The Company's effective tax rate will be reduced during future periods if it is determined these tax benefits are realizable. The Company had approximately $1.0 million and $0.9 million accrued for the payment of interest and penalties as of January 23, 2016 and July 25, 2015, respectively. Interest expense related to unrecognized tax benefits for the Company was immaterial.
