Income Tax Disclosure [Abstract]
Income Taxes	NOTE 7. INCOME TAXES Our effective tax rate for the three months ended April 2, 2021 was 23.6% as compared to 119.7% for the three months ended March 27, 2020. The year-over-year decrease in the effective tax rate for the three months ended April 2, 2021 as compared to the comparable period in the prior year was primarily due to a non-deductible book goodwill impairment recognized in the three months ended March 27, 2020. Our effective tax rate for 2021 and 2020 differs from the U.S. federal statutory rate of 21% due primarily to the effect of state taxes and foreign taxable earnings at a rate different from the U.S. federal statutory rate. Additionally, in 2020, there was an unfavorable impact related to a non-deductible book goodwill impairment.
