Income Taxes	10.Income Taxes The effective income tax rate for the first half of fiscal 2018 was a provision rate of (0.2)% compared to a provision rate of (0.2)% for the first half of fiscal 2017. Income tax expense for the interim periods was computed using the effective tax rate estimated to be applicable for the full fiscal year. The effective tax rate reflects the tax effect of the establishment of a valuation allowance against deferred tax assets in the second quarter of fiscal 2016, and the effect of not recognizing the benefit of losses incurred in fiscal 2018 and 2017 in jurisdictions where the Company concluded it is more likely than not that such benefits would not be realized. The Company assesses its ability to realize deferred tax assets throughout the fiscal year. As a result of this assessment during the second quarter of fiscal 2016, the Company concluded that it was more likely than not that the Company would not realize its deferred tax assets. Therefore, in the second quarter of fiscal 2016, the Company recorded a $31.7 million increase to provision for income taxes in order to establish a valuation allowance against such net deferred tax assets. As of January 27, 2017, the valuation allowance increased to $137.7 million, which was primarily related to an increase in losses incurred during fiscal 2017. The Company will continue to evaluate all of the positive and negative evidence in future periods and will make a determination as to whether it is more likely than not that all or a portion of its deferred tax assets will be realized in such future periods. At such time as the Company determines that it is more likely than not that all or a portion of its deferred tax assets are realizable, the valuation allowance will be reduced or released in its entirety, and the corresponding benefit will be reflected in the Company’s tax provision. Deferred tax liabilities associated with indefinite-lived intangibles cannot be considered a source of taxable income to support the realization of deferred tax assets because these deferred tax liabilities will not reverse until some indefinite future period when these assets are either sold or impaired for book purposes. The establishment of a valuation allowance does not have any impact on cash, nor does such an allowance preclude the Company from using its loss carryforwards or utilizing other deferred tax assets in the future. As of July 28, 2017 and January 27, 2017, the Company had not accrued any liabilities related to unrecognized tax benefits, and had also not accrued any interest and penalties related to uncertain tax positions for the relevant periods. The Company files income tax returns in the U.S. federal jurisdiction and in various states. The Company is subject to examinations by the major tax jurisdictions in which it files for the tax years 2011 forward.
