Income Taxes	3 Months Ended
Apr. 02, 2016
Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes For the three months ended April 2, 2016 and April 4, 2015, we recorded an income tax provision of approximately $1.9 million and $24.7 million, respectively. The income tax provision for the three months ended April 2, 2016 represents tax at the federal, state and foreign statutory tax rates adjusted for withholding taxes, changes in uncertain tax positions, changes in the U.S. valuation allowance, as well as other non-deductible items in the United States and foreign jurisdictions. The difference between the U.S. federal statutory tax rate of 35% and our effective tax rate is primarily due to a valuation allowance increase in the United States and income earned in lower tax rate jurisdictions, for which no U.S. income tax has been provided, because we intend to permanently reinvest these earnings outside of the United States. During the first quarter of 2015, we concluded that it was not more-likely-than-not that we would be able to realize the benefit of our remaining U.S. deferred tax assets, resulting in an increase to the valuation allowance and an increase to the tax provision of $21.0 million. We based this conclusion on changes to our expected operations in the United States as a result of the acquisition of Silicon Image. We exercised significant judgment and considered estimates about our ability to generate revenue and gross profits sufficient enough to offset expenditures in future periods within the United States. We are subject to federal income tax as well as income tax of multiple state and foreign jurisdictions. We are no longer subject to income tax examinations for the following jurisdictions and years: federal, for years before 2012, state and local, for years before 2011, or foreign, for years before 2009. However, U.S. federal net operating loss ("NOL") and credit carryforwards from all years are subject to examination and adjustments for at least three years following the year in which we used the attributes. Our French income tax returns are currently under examination for 2011 and 2012, as well as our Singapore income tax return for 2012. We are not under examination in any other jurisdiction. We believe that it is reasonably possible that $0.2 million of unrecognized tax benefits and less than $0.1 million of associated interest and penalties could be recognized during the next twelve months. The $0.2 million potential change would represent a decrease in unrecognized tax benefits, comprised of items related to tax filings for years that will no longer be subject to examination under expiring statutes of limitations. We have U.S. federal NOL carryforwards (pretax) of approximately $339.9 million at January 2, 2016 that expire at various dates between 2023 and 2035. We have state net operating loss carryforwards (pretax) of approximately $239.9 million at January 2, 2016 that expire at various dates from 2016 through 2035. We also have federal and state credit carryforwards of $48.2 million and $55.9 million, respectively at January 2, 2016, of which $53.4 million do not expire. The remaining credits expire at various dates from 2016 through 2034. Our liability for uncertain tax positions was $24.4 million and $23.3 million at April 2, 2016 and January 2, 2016, respectively, and is recorded as a component of other long-term liabilities on our Consolidated Balance Sheets. We are not currently paying U.S. federal income taxes and do not expect to pay such taxes until we fully utilize our tax NOL and credit carryforwards. We expect to pay a nominal amount of state income tax. We are paying foreign income and withholding taxes, which are reflected in income tax expense in our Consolidated Statements of Operations and are primarily related to the cost of operating offshore activities and subsidiaries. We accrue interest and penalties related to uncertain tax positions in income tax expense.
