Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes We are subject to federal and state income tax as well as income tax in the foreign jurisdictions in which we operate. For the second quarter of fiscal 2019 and fiscal 2018, we recorded an income tax expense of approximately $0.2 million and $1.3 million, respectively, and for the first six months of fiscal 2019 and fiscal 2018, we recorded an income tax expense of approximately $0.4 million and $1.9 million, respectively. Income taxes for the three and six month periods ended June 29, 2019 and June 30, 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 and six months ended June 29, 2019 resulted from foreign income and withholding taxes offset with release of uncertain tax positions due to lapsing of the statute of limitations. For the three and six months ended June 30, 2018, the difference resulted from an increase in the valuation allowance that offset expected tax benefit in the United States, foreign rate differential and withholding taxes, zero tax rate in Bermuda which resulted in no tax benefit for the pretax loss in Bermuda, and discrete benefit from the release of uncertain tax positions. Through June 29, 2019, we continued to evaluate the valuation allowance position in the United States and concluded that we should maintain a full 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 taxable profits sufficient to offset expenditures in future periods within the U.S. It is reasonably possible that during the next twelve months, we will establish a sustained level of profitability in the U.S. As a result, we may reverse a significant portion of the valuation allowance recorded against our U.S. deferred tax assets. The reversal would result in an income tax benefit for the quarterly and annual fiscal period in which we release the valuation allowance. 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 we will realize the net deferred tax assets in future periods. At June 29, 2019, it is reasonably possible that $1.5 million of unrecognized tax benefits and $0.1 million of associated interest and penalties could be recognized during the next twelve months. The $1.6 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. Our liability for uncertain tax positions (including penalties and interest) was $25.9 million and $26.3 million at June 29, 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 $24.8 million is netted against deferred tax assets. We are not currently paying U.S. federal income taxes and do not expect to pay such taxes until we fully utilize our tax net operating loss ("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.
