The effective income tax rates for the three months ended March 27, 2022 and March 28, 2021 were 17.1% and 14.2%, respectively. The effective income tax rate for the three months ended March 27, 2022 includes higher tax expense resulting from a U.S. law effective in 2022 requiring capitalization of certain research and development expenditures. The effective income tax rate for the three months ended March 28, 2021 reflects tax benefits associated with the Z-Medica acquisition and the 2021 Restructuring Plan. The effective income tax rates for both periods reflect a net tax benefit related to share-based compensation and a tax benefit from research and development tax credits.
