The increase in the effective tax rate for the three months ended December 31, 2022 as compared to the three months ended January 1, 2022 is primarily related to the impact of mandatory capitalization of R&D expenditures to foreign minimum tax.
For the three months ended December 31, 2022, the effective tax rate is slightly lower than the U.S. federal statutory tax rate primarily due to foreign income earned in lower tax jurisdictions, tax incentives and tax credits, partially offset by foreign minimum tax.
