The Company recognizes interest and penalties related to unrecognized tax benefits as components of income tax expense. The Company and its subsidiaries are subject to U.S. federal income taxes and the income tax obligations of various state and local jurisdictions. Periods after fiscal 2013 remain subject to examination by the IRS. With few exceptions, the Company is not subject to state income tax examination by tax authorities for taxable years prior to fiscal 2012. As of July 29, 2017, the end of the second quarter of fiscal 2017, the Company had no other ongoing audits in various jurisdictions and does not expect the liability for unrecognized tax benefits to significantly increase or decrease in the next twelve months. As of July 29, 2017, 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 was allowed related to certain tax benefits. As of July 29, 2017, the Company has federal and state net operating loss carryforwards ("NOLs") which will reduce future taxable income. Approximately $36.2 million in net federal tax benefits are available from federal NOLs. An additional $1.2 million is available in net tax credit carryforwards. The state NOLs will result in net state tax benefits of approximately $2.5 million. Sections 382 and 383 of the Internal Revenue Code limit the annual utilization of certain tax attributes, including NOL 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.
