Income Tax Disclosure [Abstract]
Income Taxes	NOTE 8. INCOME TAXES Our effective tax rates for the three and six month periods ended June 26, 2020 were 14.9% and 23.2%, respectively, as compared to 14.2% and 14.5% for the three and six month periods ended June 28, 2019, respectively. There were no significant differences in the year-over-year effective tax rate for the three month period ended June 26, 2020 compared to the three month period ended June 28, 2019. The year-over-year increase in the effective tax rate for the six month period ended June 26, 2020 compared to the six month period ended June 28, 2019 was due primarily to a non-deductible goodwill impairment and tax costs associated with repatriating a portion of our previously reinvested earnings outside of the United States. For the six month period ended June 26, 2020, these factors were partially offset by favorable impacts of a higher mix of income in jurisdictions with lower tax rates than the U.S. federal statutory rate of 21% and increases in favorable impacts of certain federal and international tax benefits. Our effective tax rate for both periods in 2020 and 2019 differs from the U.S. federal statutory rate of 21% due primarily to the positive and negative effects of the Tax Cuts and Jobs Act (“TCJA”), U.S. federal permanent differences, the impact of credits and deductions provided by law, and current year earnings outside the United States that are indefinitely reinvested and taxed at rates lower than the U.S. federal statutory rate. Specific to 2020, our effective tax rate also differs from the U.S. federal statutory rate of 21% due to a non-deductible goodwill impairment and the tax costs associated with repatriating a portion of our previously reinvested earnings outside of the United States. On March 27, 2020, the U.S. federal government enacted the Coronavirus Aid, Relief, and Economic Security Act (the “CARES Act”). The CARES Act is an emergency economic stimulus package in response to the COVID-19 outbreak which, among other things, contains numerous income tax provisions. Some of these tax provisions are expected to be effective retroactively for years ending before the date of enactment. We anticipate the provisions of the CARES Act will impact income tax in 2020; however, we have not identified material impacts to the tax provision as of June 26, 2020. We will continue to evaluate the impact of the CARES Act as new clarifying guidance is issued throughout 2020.
