Income Taxes	13. Income Taxes For the three and nine months ended July 30, 2011, the Company recorded an income tax benefit of $10.3 million and $16.6 million, respectively, primarily as a result of discrete benefits from the retroactive reinstatement of the federal research and development tax credit provision as a result of the Tax Relief, Unemployment Insurance Reauthorization, and Job Creation Act of 2010 (the "Tax Relief Act"), reserve releases from the settlement with the IRS regarding the Company's fiscal year 2007 and 2008 audits, and reserve release from the expiration of the statute of limitation, offset by foreign tax expense. For the three and nine months ended July 31, 2010, the Company recorded an income tax benefit of $14.9 million and $15.0 million, respectively. The total amount of unrecognized tax benefits of $140.8 million as of July 30, 2011 would affect the Company's effective tax rate, if recognized. Although the timing of the closure of audits is highly uncertain, it is reasonably possible that the balance of unrecognized tax benefits could significantly change during fiscal year 2011. The IRS and other tax authorities regularly examine our income tax returns. We are currently under negotiations with the Appeals division of the IRS for the audit of fiscal years 2004 through 2006, which we expect to resolve during the next twelve months. In addition, we are in negotiations with foreign tax authorities to receive correlative relief on transfer pricing settlements with the IRS. We believe that our reserves for unrecognized tax benefits are adequate for all open tax years. The timing of the resolution of income tax examinations, as well as the amounts and timing of related settlements, is highly uncertain. The Company believes that before the end of fiscal year 2011, it is reasonably possible that either certain audits will conclude or the statute of limitations relating to certain income tax examination periods will expire, or both. As such, after we reach settlement with the IRS, we expect to record a corresponding adjustment to our unrecognized tax benefits. Given the uncertainty as to settlement terms, the timing of payments and the impact of such settlements on other uncertain tax positions, the range of estimated potential decreases in underlying uncertain tax positions is between $0 and $24 million in the next twelve months. In May 2011, the Company received the IRS revenue agent's report for fiscal years 2007 and 2008. The IRS is contesting the Company's transfer pricing for the cost sharing and buy-in arrangements with its foreign subsidiaries. The IRS' proposed adjustment would offset approximately $317.4 million of the Company's net operating loss carryforwards. In June 2011, the Company filed a protest with the Appeals Office of the IRS to challenge the IRS' proposed adjustment and assessment. The Franchise Tax Board is auditing Foundry's California income tax returns for calendar years 2006 and 2007. These audits and appeals are still ongoing and the Company believes its reserves are adequate to cover any potential assessments and settlements that may result from these examinations. Due to the availability of net operating losses and credits, the Company does not expect a significant tax liability from the settlement of the audits. The Company believes that sufficient positive evidence exists from historical operations and projections of taxable income in future years to conclude that it is more likely than not that the Company will realize its deferred tax assets. Accordingly, the Company applies a valuation allowance only on the deferred tax assets relating to capital loss and investments loss carryforwards, due to limited carryforward periods and the character of such tax attributes. As part of the 2011-2012 budget, the Governor of the State of California has introduced tax proposals affecting future state income tax apportionment that may have a significant impact on the Company's ability to realize certain California deferred tax assets. The Company will reevaluate the realization of its California deferred tax assets if and when the current law changes.
