Income Taxes	3 Months Ended
Mar. 30, 2019
Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes We are subject to federal and state income tax as well as income tax in the various foreign jurisdictions in which we operate. For the three months ended March 30, 2019, we recorded an income tax expense of approximately $0.2 million, and for the three months ended March 31, 2018, we recorded an income tax expense of approximately $0.6 million. Income taxes for the three month periods ended March 30, 2019 and March 31, 2018 represent 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 21% and our effective tax rate for the three months ended March 30, 2019 results from foreign income and withholding taxes offset with release of uncertain tax positions due to lapsing of the statute of limitations. Through March 30, 2019, we continued to evaluate the valuation allowance position in the United States and concluded we should maintain a valuation allowance against the net federal and state deferred tax assets. In making this evaluation, we exercised significant judgment and considered estimates about our ability to generate revenue and gross profits sufficient to offset expenditures in future periods within the United States. We will continue to evaluate both positive and negative evidence in future periods to determine if we should recognize more deferred tax assets. We do not have a valuation allowance in any foreign jurisdictions as we have concluded it is more likely than not that we will realize the net deferred tax assets in future periods. We believe that the years that our tax returns remain subject to examination by taxing authorities are 2015 for federal income taxes, 2014 for state income taxes, and 2012 for foreign income taxes, including years ending thereafter. However, to the extent allowed by law, the tax authorities may have the right to examine prior periods where net operating losses or tax credits were generated and carried forward, and make adjustments up to the amount of the net operating losses or credit carryforward amount. Our income tax returns are under examination in the Philippines for fiscal years 2016 and 2017. At March 30, 2019, it is reasonably possible that $1.2 million of unrecognized tax benefits and $0.1 million of associated interest and penalties could be recognized during the next twelve months. The $1.3 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. At December 29, 2018, we had U.S. federal net operating loss ("NOL") carryforwards (pretax) of approximately $365.3 million that expire at various dates between 2019 and 2037. We had state NOL carryforwards (pretax) of approximately $147.6 million that expire at various dates from 2019 through 2037. We also had federal and state credit carryforwards of $51.5 million and $61.2 million, respectively. Of the total $61.2 million state credit carryforwards, $60.2 million do not expire. The remaining credits expire at various dates from 2019 through 2037. Our liability for uncertain tax positions (including penalties and interest) was $25.9 million and $26.3 million at March 30, 2019 and December 29, 2018, respectively, and is recorded as a component of Other long-term liabilities on our Consolidated Balance Sheets. The remainder of our uncertain tax position exposure of $24.9 million is netted against deferred tax assets. The Tax Cuts and Jobs Act, enacted December 22, 2017, required a deemed repatriation of deferred foreign earnings as of December 30, 2017 and, as a result, no future U.S. taxes should be due on these earnings because of enactment of a 100% dividends received deduction. We had no impact from this transition tax due to utilization of NOL carryforwards. Foreign earnings may be subject to withholding taxes in local jurisdictions if they are distributed and repatriated in the United States. 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.
