Income Taxes	3 Months Ended
Dec. 29, 2012
Income Tax Disclosure [Abstract]
Income Taxes	INCOME TAXES Income tax expense includes a provision for federal, state and foreign taxes based on the annual estimated effective tax rate applicable to us and our subsidiaries, adjusted for items which are considered discrete to the period. Our estimated effective tax rate for the three months ended December 29, 2012 was 25.7%. Our effective tax rate for the three months ended December 29, 2012 was lower than the statutory rate of 35% primarily due to permanent differences related to the benefit of income subject to foreign tax rates that are lower than U.S. tax rates, the benefit of foreign tax credits and the benefit of releasing foreign tax reserves accrued under ASC 740-10 (formerly FASB Financial Interpretation No. 48, "Accounting for Uncertainty in Income Taxes") and related interest. These amounts are partially offset by deemed dividend inclusions under the Subpart F tax rules, stock compensation not deductible for tax purposes and limitations on the deductibility of compensation under IRC Section 162(m). Determining the consolidated provision for income taxes, income tax liabilities and deferred tax assets and liabilities involves judgment. We calculate and provide for income taxes in each of the tax jurisdictions in which we operate, which involves estimating current tax exposures as well as making judgments regarding the recoverability of deferred tax assets in each jurisdiction. The estimates used could differ from actual results, which may have a significant impact on operating results in future periods. As of December 29, 2012, the total amount of gross unrecognized tax benefits was $25.8 million including gross interest and penalties of $1.3 million, of which $16.3 million, if recognized, would affect our effective tax rate. Our total gross unrecognized tax benefits, net of certain deferred tax assets, were classified as other long-term liabilities in the condensed consolidated balance sheets. Our policy is to include interest and penalties related to unrecognized tax benefits within the provision for income taxes. As of December 29, 2012, the total amount of gross interest and penalties accrued was $1.3 million, which is classified as other long-term liabilities in the condensed consolidated balance sheets. We are subject to taxation and file income tax returns in the U.S. federal jurisdiction and in many state and foreign jurisdictions. For U.S. federal income tax purposes, all years prior to 2009 are closed to examination. In our major state jurisdiction and our major foreign jurisdictions, the years prior to 2008 and 2006, respectively, are closed to examination. In December 2011 and January 2012, our three German subsidiaries received notices of tax audits for the fiscal years 2006 through 2010. These audits are currently in process. Management believes that it has adequately provided for any adjustments that may result from tax examinations. The Company regularly engages in discussions and negotiations with tax authorities regarding tax matters in various jurisdictions. It is reasonably possible that certain federal, foreign and state tax matters may be concluded in the next 12 months. Although the timing of the resolution and/or closure of audits is highly uncertain, it is reasonably possible that the balance of net unrecognized tax benefits including interest and penalties at December 29, 2012 could be reduced by approximately $0.2 million to $2.4 million in the next 12 months. The American Taxpayer Relief Act of 2012 (“the Act”), was enacted on January 2, 2013. Under the Act, the federal research and development credit was retroactively extended for amounts paid or incurred after December 31, 2011 through December 31, 2013. The look-through treatment of payments between related controlled foreign corporations under the Subpart F rule was also retroactively extended for the same time period. The effects of the change in the tax law will be recognized in our second quarter of fiscal 2013, which is the quarter that the law was enacted. Accordingly, we anticipate that prior period research and development credits of approximately $1.0 million to $2.5 million from the last three quarters of fiscal 2012 and the first quarter of fiscal 2013 will be recognized in the second quarter of fiscal 2013. In addition, we also anticipate a reduction in the tax impact of the Subpart F income inclusion of up to approximately $0.5 million. Deferred Income Taxes As of December 29, 2012, our condensed consolidated balance sheet included net deferred tax assets, before valuation allowance, of approximately $55.2 million, which consists of tax credits carryovers, accruals and reserves, competent authority offset to transfer pricing tax reserves, employee stock-based compensation expenses and certain other liabilities. Management periodically evaluates the realizability of our net deferred tax assets based on all available evidence, both positive and negative. The realization of net deferred tax assets is solely dependent on our ability to generate sufficient future taxable income in the applicable jurisdictions during periods prior to the expiration of tax statutes to fully utilize these assets. After evaluating all available evidence, we have determined that it is “more likely than not” that a portion of the deferred tax assets would not be realized and we have a total valuation allowance of $9.1 million as of December 29, 2012. We intend to maintain the valuation allowance until sufficient positive evidence exists to support reversal of the valuation allowance.
