Income Tax Disclosure [Abstract]
Income Taxes	NOTE 12: 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 three months ended March 29, 2013, the Company recorded a benefit from income taxes of $5.5 million, compared to a benefit from income taxes of $0.6 million for the same period a year ago, inclusive of discrete items. The increase in the benefit from income taxes in the three months ended March 29, 2013, compared to the same period in 2012, was primarily attributable to the reinstatement of the federal R&D tax credit retroactively from January 1, 2012, and an increase in loss from continuing operations in the three months ended March 29, 2013, compared to the same period in 2012. For the three months ended March 29, 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, the differential in foreign tax rates, non-deductible stock-based compensation expense and non-deductible amortization on foreign intangibles, and federal R&D credits. The discrete items recorded in the first three months of 2013 primarily related to the increase in the valuation allowance on California R&D tax credits, the reinstatement of the federal R&D tax credit, and accrued interest on uncertain tax positions. For the three months ended March 30, 2012, 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, 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 three months of 2012 related to accrued interest on uncertain tax positions, and foreign currency translation adjustments. 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 2008 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. The Company is under audit by the US Internal Revenue Service for the 2008, 2009 and 2010 tax years. In addition, the statute of limitations on our 2008 and 2009 U.S. corporate income tax return has been extended to September 2013. A subsidiary of the Company is under an audit, which commenced in the first quarter of 2012, by the Israel tax authority for the years 2007 through 2010. If, upon the conclusion of these audits, the ultimate determination of taxes owed in the U.S. or Israel is for an amount in excess of the tax provision we have recorded in the applicable period, our overall tax expense, effective tax rate, operating results and cash flow could be materially and adversely impacted in the period of adjustment. 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 $60.8 million as of March 29, 2013. If all of these unrecognized tax benefits 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 related statutes of limitation that are to expire during that period are not extended. The Company recognizes interest and possible penalties related to uncertain tax positions in income tax expense. During the three months ended March 29, 2013, the Company recorded a net increase of $0.6 million for interest and possible penalties related to uncertain tax positions, resulting in a balance at March 29, 2013 of $7.7 million.

NOTE 12: 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 three months ended March 29, 2013, the Company recorded a benefit from income taxes of $5.5 million, compared to a benefit from income taxes of $0.6 million for the same period a year ago, inclusive of discrete items. The increase in the benefit from income taxes in the three months ended March 29, 2013, compared to the same period in 2012, was primarily attributable to the reinstatement of the federal R&D tax credit retroactively from January 1, 2012, and an increase in loss from continuing operations in the three months ended March 29, 2013, compared to the same period in 2012.

For the three months ended March 29, 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, the differential in foreign tax rates, non-deductible stock-based compensation expense and non-deductible amortization on foreign intangibles, and federal R&D credits. The discrete items recorded in the first three months of 2013 primarily related to the increase in the valuation allowance on California R&D tax credits, the reinstatement of the federal R&D tax credit, and accrued interest on uncertain tax positions.
