Income Taxes
The effective tax rates for the three and nine months ended July 2, 2016 were 30.9% and 27.5%, respectively. The effective tax rates for the three and nine months ended July 4, 2015 were 28.4% and 26.8%, respectively. The effective tax rates for these periods are lower than the U.S. federal statutory tax rate primarily due to a significant portion of our earnings that come from foreign operations with lower tax rates and the recognition and timing of U.S. research and development tax credits. In addition, we also benefited from the reversal of accruals for certain tax exposures outside the U.S. whose statutes of limitations expired during these periods.
