Income Tax Disclosure [Abstract]
Income Taxes	INCOME TAXES The income tax provision includes federal, state and local and foreign income taxes and is based on the application of a forecasted annual income tax rate applied to the current quarter’s year-to-date pre-tax income (loss). In determining the estimated annual effective income tax rate, the Company estimates the annual impact of certain factors, including projections of the Company’s annual earnings, taxing jurisdictions in which the earnings will be generated, state and local income taxes, the Company’s ability to use tax credits and net operating loss carryforwards, and available tax planning alternatives. Discrete items, including the effect of changes in tax laws, tax rates, and certain circumstances with respect to valuation allowances or other unusual or non-recurring tax adjustments, are reflected in the period in which they occur as an addition to, or reduction from, the income tax provision, rather than being included in the estimated annual effective income tax rate. For the nine months ended September 27, 2013, the difference between the recorded benefit from income taxes and the tax provision, based on the federal statutory rate of 35%, was primarily attributable to the net of various discrete items, non-deductible amortization on foreign intangibles, the differential in foreign tax rates, the federal research and development tax credit, and non-deductible stock-based compensation expense. The discrete items recorded in the first nine months of 2013 primarily related to the benefit associated with the reversal of previously recorded federal and, to a lesser extent, foreign income taxes as a result of the expiration of the applicable statutes of limitations in the U.S. for 2008 and 2009 and in foreign jurisdictions for various years, and the benefit associated with the reinstatement of the federal research and development tax credit for 2012, offset partially by the increase in the valuation allowance on the California research and development tax credit and accrued interest on uncertain tax positions. For the nine months ended September 28, 2012, the difference between the recorded provision for income taxes and the tax provision, based on the federal statutory rate of 35%, was primarily attributable to the net of various discrete items, the differential in foreign tax rates, non-deductible stock-based compensation expense, and non-deductible amortization on foreign intangibles. The discrete items recorded in the first nine months of 2012 primarily related to the increase in the valuation allowance on the California research and development tax credit and accrued interest on uncertain tax positions, offset partially by the benefit associated with the reversal of previously recorded foreign income taxes due to the expiration of the statute of limitation in the foreign jurisdictions. The Company files federal, state, and foreign income tax returns in jurisdictions with varying statutes of limitations during which such tax returns may be audited and adjusted by the relevant tax authorities. The U.S. Internal Revenue Service has concluded its audit for the 2008 and 2009 tax years. In addition, the statute of limitations on the Company's 2008 and 2009 U.S. corporate income tax return expired in September 2013 and, as a result, in the third quarter of 2013, the Company recorded a discrete net tax benefit of $38.4 million related to the release of tax reserves for uncertain tax positions for those tax years. The 2010 through 2012 tax years generally remain subject to examination by federal and most state tax authorities. In significant foreign jurisdictions, the 2006 through 2012 tax years generally remain subject to examination by their respective tax authorities. In the third quarter of 2013, the Israeli tax authority concluded its audit of a subsidiary of the Company for the years 2007 through 2010, and a final settlement was made with the Israeli tax authority. The settlement did not have a material impact on the Company's overall tax expense, deferred tax assets realization, effective tax rate, operating results or cash flow. In compliance with applicable guidance for accounting for uncertainty in income taxes, the Company had gross unrecognized tax benefits, which include interest and penalties, of approximately $59.2 million as of December 31, 2012, and approximately $22.3 million as of September 27, 2013. If all of the unrecognized tax benefits at September 27, 2013 were recognized, the entire amount would impact the provision for income taxes. The unrecognized tax benefits may decrease significantly within the next 12 months if a related statute of limitations that is currently set to expire during that period is not extended. The realization of our deferred tax assets is dependent upon the generation of sufficient U.S and foreign taxable income in the future to offset against those assets. We may not have sufficient taxable income in the future to determine that we will be able to realize some significant portion of our deferred tax assets. As a result, an additional valuation allowance against our deferred tax assets may be required in the period in which such a determination is made, and our operating results could be materially and adversely impacted in the period of adjustment. The Company recognizes interest and possible penalties related to uncertain tax positions in income tax expense. During the nine months ended September 27, 2013, as a result of the expiration of the applicable statutes of limitations in the U.S. for 2008 and 2009 and in foreign jurisdictions for various years, the Company recorded a net decrease of $5.8 million for interest and possible penalties related to uncertain tax positions, resulting in a balance at September 27, 2013 of $1.4 million.
