Income Tax Expense (Benefit) [Abstract]
Income Tax Disclosure [Text Block]	Income Taxes We file income tax returns with the Internal Revenue Service (“IRS”) and in various states and foreign jurisdictions. In 2008, the IRS completed field examinations for 2002 through 2004 and proposed an additional tax liability of $34.5 million, excluding interest. We contested this proposed additional tax liability in the IRS Office of Appeals and resolved several of the issues. On December 8, 2011, the IRS issued a Statutory Notice of Deficiency, revising the assessment of additional taxes for 2002 through 2004 to $19.8 million, excluding interest. The Notice relates primarily to inter-company adjustments between related companies, computational adjustments to the R&D Credit and reductions to the benefits of tax credit carrybacks and carryforwards to subsequent years. On March 6, 2012, we filed a petition in the U.S. Tax Court to request a redetermination of the tax deficiency regarding certain IRS adjustments for 2004. We deposited $18.0 million as a cash bond with the IRS in 2008, and converted this amount to tax payments in March 2012. On May 8, 2012, the IRS filed its petition response in the Tax Court, in which the IRS conceded the R&D Credit adjustment for 2004. In June 2012, the federal statute of limitations for the 2002 and 2003 tax years expired. In addition, in 2010 the IRS completed field examinations for 2005 through 2007 and proposed an additional tax liability of $34.2 million, excluding interest. On January 23, 2012, the IRS issued a Statutory Notice of Deficiency, revising the assessment of additional taxes for 2005 through 2007 to $21.4 million, excluding interest. The Notice relates primarily to intercompany adjustments between related companies and reductions to the benefits of tax credit carrybacks and carryforwards to subsequent years. On April 20, 2012, we filed a petition in the U.S. Tax Court to request a redetermination of the tax deficiencies regarding certain IRS adjustments for 2005 through 2007. On June 21, 2012, the IRS filed its petition response in the Tax Court. We believe we have made adequate tax payments and/or accrued adequate amounts for our tax liabilities for 2004 through 2007 and that the outcome of the above matters will not have a material adverse effect on our consolidated operating results, cash flows or financial position. Other significant jurisdictions in which we are or may be subject to examination for fiscal years 2002 forward include China (including Hong Kong), Ireland, Malaysia, Japan, United Kingdom and the state of California. We believe we have made adequate tax payments and/or accrued adequate amounts such that the outcome of these audits will have no material adverse effect on our consolidated operating results. Due to the potential resolution of various tax examinations, and the expiration of various statutes of limitations, it is possible that our gross unrecognized tax benefits may change within the next twelve months. However, given the number of years remaining subject to examination and the number of matters being examined, we are unable to estimate the full range of possible adjustments to the balance of gross unrecognized tax benefits. Our effective tax rate reflects the impact of a significant amount of our earnings being taxed in foreign jurisdictions at rates below the U.S. statutory tax rate. Our effective tax rate for the three months ended June 29, 2012 was -2.5%, compared with 9.9% for the three months ended July 1, 2011. The net decrease in our effective tax rate was primarily due to higher one-time tax benefits in 2012 compared to 2011, partially offset by the absence of a U.S. federal research and development tax credit in 2012, due to its expiration in 2011. During the three months ended June 29, 2012, the effective tax rate includes a $24.4 million net tax benefit primarily associated with the release of liabilities for uncertain tax positions upon the expiration of the federal statutes of limitation, the reassessment and recognition of previously unrecognized federal tax benefits, and the reversal of the related interest accruals. Our effective tax rate for the six months ended June 29, 2012 was -0.7%, compared with 9.3% for the six months ended July 1, 2011. The net decrease in our effective tax rate was primarily due to higher one time tax benefits in 2012 compared to 2011, partially offset by the absence of a U.S. federal research and development tax credit in 2012, due to its expiration in 2011. During the six months ended June 29, 2012, the effective tax rate includes the following net tax benefits associated with the release of liabilities for uncertain tax positions: 1) a $24.4 million net tax benefit primarily associated with the expiration of the federal statutes of limitation, the reassessment and recognition of previously unrecognized federal tax benefits, and the reversal of the related interest accruals; 2) a $6.9 million net tax benefit as a result of a Statutory Notice of Deficiency received from the IRS for 2005 to 2007; and 3) a $5.2 million net tax benefit as a result of the expiration of the statutes of limitations for certain foreign jurisdictions. As of June 29, 2012, we had $251.0 million of unrecognized tax benefits that, if recognized, would impact our effective tax rate. On December 31, 2011, we had $284.9 million of unrecognized tax benefits. We are unable to make a reasonable estimate as to when cash settlements with the relevant taxing authorities will occur. We recognize interest and penalties related to uncertain tax positions in our income tax provision. We had accrued approximately $45.7 million and $54.8 million for the payment of interest and penalties related to uncertain tax positions as of June 29, 2012 and December 31, 2011, respectively.
