Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes Our income tax benefit of $0.5 million for the six months ended June 30, 2012, primarily reflects $0.1 million of expense related to income taxes at certain of our foreign operations, $0.9 million of foreign withholding taxes and $1.2 million of deferred taxes on undistributed earnings from our investment in J-Devices Corporation ("J-Devices") offset by a net $2.7 million reduction in unrecognized tax benefits. Our income tax expense reflects income taxed in foreign jurisdictions where we benefit from tax holidays. At June 30, 2012, we had U.S. net operating loss carryforwards totaling $367.6 million, which expire at various times through 2031. Additionally, at June 30, 2012, we had $83.9 million of non-U.S. net operating loss carryforwards, substantially all 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 decreased from $7.9 million at December 31, 2011 to $4.8 million as of June 30, 2012, primarily because of a $4.0 million reduction as a result of a favorable ruling request related to revenue attribution and a $0.3 million settlement of a contested prior year deduction in a foreign jurisdiction, which were partially offset by $1.2 million of net additions related to the deductibility of certain expenses. Substantially all of the remaining balance of our unrecognized tax benefits at June 30, 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.
