Income Taxes	5. Income Taxes The Company is currently open to audit under statutes of limitation by the Internal Revenue Service, various foreign jurisdictions, and state jurisdictions for the fiscal years ended July 31, 2008 through July 31, 2014. However, limited adjustments can be made to federal and state tax returns in earlier years in order to reduce net operating loss carryforwards. As of January 24, 2015 and July 31, 2014, the Company had a liability of $1.79 million for taxes, interest and penalties for unrecognized tax benefits related to various foreign income tax matters. As of January 24, 2015 and July 31, 2014, the Company had $0.6 million accrued for interest and penalties related to uncertain tax positions. The Company accounts for interest and penalties related to uncertain tax positions as part of its provision for federal, international and state income taxes. This liability is subject to change, perhaps materially. As a result of having substantial net operating losses over recent years and no current operations, the Company determined that it is more likely than not that our deferred tax assets will not be realized. Therefore, we maintain a valuation allowance on the full amount of our net deferred tax assets. If the Company generates future taxable income against which these tax attributes may be applied, the net operating loss carryforwards may be utilized and some or all of the valuation allowance reversed. If the valuation allowance is reversed, portions would be recorded as an increase to paid-in capital and the remainder would be recorded as a reduction in income tax expense. The occurrence of ownership changes, as defined in Section 382 of the Internal Revenue Code of 1986, as amended (the “Code”), is not controlled by the Company, and could significantly limit the amount of net operating loss carryforwards and research and development credits that can be utilized annually to offset future taxable income. The Company completed an updated Section 382 study for the period April 2006 through July 31, 2011 and the results of this study showed that no ownership change within the meaning of the Code had occurred from April 2006 through July 31, 2011. The Company has not, however, conducted a Section 382 study for any periods after July 31, 2011 and, accordingly, the Company cannot provide any assurance that an ownership change within the meaning of the Code has not occurred since that date.
