Income Tax Disclosure [Text Block]	Note 10 - 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 first quarter of fiscal 2020 and fiscal 2019, we recorded income tax expense of approximately $0.4 million and $0.2 million, respectively. Income taxes for the three month period ended March 28, 2020 and March 30, 2019 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 28, 2020 resulted primarily from a decrease in the valuation allowance that offset expected tax expense in the United States, foreign withholding tax expense, discrete impact from uncertain tax positions, and foreign rate differential primarily due to zero tax rate in Bermuda. For the three months ended March 30, 2019, 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 a benefit from the release of uncertain tax positions. Through March 28, 2020, 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 will realize the 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. At March 28, 2020, it is reasonably possible that $2.3 million of unrecognized tax benefits and $0.5 million of associated interest and penalties could be recognized during the next twelve months. The $2.8 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 $24.3 million and $24.6 million at March 28, 2020 and December 28, 2019, 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 isnetted 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.
