Income Tax Disclosure [Abstract]
Income Taxes	Note 6—Income Taxes Income tax benefit was $10.5 million on pre-tax income of $6.6 million for the six months ended July 4, 2015, as compared to an income tax expense of $2.0 million on pre-tax loss of $5.2 million for the six months ended June 28, 2014. With the release of our federal tax valuation allowance in the United States during the fourth quarter of 2014, we are now able to realize tax benefits generated in the United States. 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 can cause material fluctuations in our estimated effective tax rate on a quarterly basis. We have therefore calculated our income tax provision for the six months ended July 4, 2015 on a discrete basis rather than using the estimated annual effective tax rate for the year, in accordance with ASC 740.
