The effective tax rates were approximately 27.0% and 29.3% for the nine months ended and 29.9% and 26.5% for the three months ended September 30, 2017 and October 1, 2016, respectively. The 2017 tax rates were favorably impacted relative to the statutory rate by excess tax benefits associated with the exercise of stock options, decreases in foreign tax rates, and from the federal research and development tax credit.
