Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes Our income tax expense of $3.4 million for the three months ended March 31, 2012, primarily reflects $2.0 million of expense related to income taxes at certain of our foreign operations, $0.5 million of foreign withholding taxes and $0.9 million of deferred taxes on undistributed earnings from our investment in J-Devices Corporation ("J-Devices"). Our income tax expense reflects income taxed in foreign jurisdictions where we benefit from tax holidays. At March 31, 2012, we had U.S. net operating loss carryforwards totaling $375.5 million, which expire at various times through 2031. Additionally, at March 31, 2012, we had $69.7 million of non-U.S. net operating loss carryforwards, the majority of which will expire at various times through 2022. We maintain a valuation allowance on all of our U.S. net deferred tax assets, including our net operating loss carryforwards. We also have valuation allowances on deferred tax assets in certain foreign jurisdictions. Such valuation allowances are released as the related tax benefits are realized on our tax returns or when sufficient net positive evidence exists to conclude it is more likely than not that the deferred tax assets will be realized. Our gross unrecognized tax benefits of $8.0 million as of March 31, 2012, did not change significantly since December 31, 2011. However, in April 2012 we received formal notification that a foreign tax authority accepted our ruling request related to revenue attribution. As a result, we will recognize a tax benefit of $4.0 million in the second quarter of 2012, which will have a favorable impact on our effective tax rate for that quarter and for 2012. Substantially all of the remaining balance of our unrecognized tax benefits at March 31, 2012, would also reduce our effective tax rate, if recognized. Our unrecognized tax benefits are subject to change as examinations of tax years are completed. Tax return examinations involve uncertainties, and there can be no assurances that the outcome of examinations will be favorable.
