Income Tax Disclosure [Abstract]
Income Taxes	Note 4—Income Taxes Income tax benefit was $9.0 million on pre-tax loss of $10.9 million for the three months ended April 2, 2016, as compared to an income tax benefit of $9.4 million on pre-tax loss of $10.6 million for the three months ended April 4, 2015. This is the result of recognizing income tax benefit of pre-tax losses in certain jurisdictions that is not offset by income tax expense in other jurisdictions with pre-tax income. As we have significant global permanent book to tax differences that exceed our estimated income before taxes on an annual basis, small changes in our estimated income before taxes or changes in year to date income before taxes between jurisdictions can cause material fluctuations in our estimated effective tax rate on a quarterly basis. We have therefore calculated our quarterly income tax provision for the fiscal quarters ended April 2, 2016 and April 4, 2015 on a discrete basis for the United States rather than using the estimated annual effective tax rate for the year, in accordance with ASC 740, Income Taxes.
