Income Tax Disclosure [Abstract]
Income Taxes	During the three months ended April 2, 2021, Income from continuing operations before income taxes was $35.6 million, while the income tax expense was $7.9 million. The effective tax rate was 22.2% for the three months ended April 2, 2021. The effective tax rate for the three months ended April 2, 2021 differed from the 2021 U.S. federal statutory rate of 21% mainly due to withholding taxes, taxable foreign exchange gains and other non-deductible expenses partially offset by the benefit of U.S. tax credits. During the three months ended April 3, 2020, Income from continuing operations before income taxes was $22.0 million, while the income tax expense was $13.2 million. The effective tax rate was 59.8% for the three months ended April 3, 2020. The effective tax rate for the three months ended April 3, 2020 differed from the 2020 U.S. federal statutory rate of 21% mainly due to the impact of additional U.S. tax on international operations and taxable foreign exchange gains offset in part by a discrete tax benefit associated with the enactment of a tax law change in India. Income taxes for the three months ended April 3, 2020 were calculated using the actual year-to-date effective tax rate, also known as the discrete method. The discrete method was used because of the high degree of uncertainty in estimating annual pretax earnings at that time caused by the COVID-19 pandemic market conditions.
