Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes For the thirteen weeks ended August 4, 2018, the Company recorded income tax expense of $63 thousand, or an effective rate of (0.9)%, compared to income tax expense of $40 thousand, or an effective rate of (0.5)%, for the second quarter of fiscal 2017. For the twenty-six weeks ended August 4, 2018, the Company recorded income tax expense of $106 thousand, or an effective rate of (0.8)%, compared to income tax expense of $92 thousand, or an effective rate of (0.8)%, for the same period of fiscal 2017. The income tax provision for the fiscal 2018 and 2017 periods is primarily driven by state taxes. As of August 4, 2018, the possibility of future cumulative losses still exists. Accordingly, the Company has continued to maintain a valuation allowance against its net deferred tax assets. A small deferred tax asset remains related to certain state tax benefits. The Company has federal and state net operating loss ("NOL") carryforwards which will reduce future taxable income. Approximately $26.1 million in net federal tax benefits are available from these federal loss carryforwards. An additional $0.8 million is available in net tax credit carryforwards. The state loss carryforwards will result in net state tax benefits of approximately $4.5 million. Sections 382 and 383 of the Internal Revenue Code limit the annual utilization of certain tax attributes, including net operating loss carryforwards, incurred prior to a change in ownership. If the Company were to experience an ownership change, as defined by Sections 382 and 383, its ability to utilize its tax attributes could be substantially limited. Depending on the severity of the annual NOL limitation, the Company could permanently lose its ability to use a significant number of its accumulated NOLs. The Company's liability for unrecognized tax benefits associated with uncertain tax positions is recorded within other non-current liabilities. There has been no material change in the reserve for unrecognized tax benefits since the end of the previous fiscal year. The Company recognizes interest and penalties related to unrecognized tax benefits as components of income tax expense. We do not expect any significant changes to the amount of unrecognized tax benefits in the next twelve months. The Company files income tax returns in the U.S. federal jurisdiction and various state and local jurisdictions. With few exceptions, the Company or its subsidiaries are no longer subject to examination prior to tax years before fiscal 2013. The Company does not have any ongoing income tax audits. The Tax Cuts and Jobs Act ("the Act") was enacted on December 22, 2017. The Act reduced the U.S. federal corporate tax rate from 35% to 21% as of January 1, 2018. The income tax effects of the Act required the remeasurement of our deferred tax assets and liabilities in accordance with ASC Topic 740. The Securities and Exchange Commission ("SEC") staff issued Staff Accounting Bulletin No. 118 ('SAB 118') that allows companies to record provisional estimates of the impacts of the Act during a measurement period of up to one year from the enactment, which is similar to the measurement period used when accounting for business combinations. The Company has estimated the effects of the Act, and those estimates have been reflected in our 2017 financial statements.
