Income Taxes	Note 16. Income Taxes The effective tax rate was 21.8% for the three months ended September 30, 2018 and 30.4% for the three months ended September 30, 2017.

The effective tax rate for the nine months ended September 30, 2018 was more than the federal statutory rate of 21% primarily due to foreign income taxed at higher rates and certain non-deductible business expenses, offset in part by $3.1 million tax benefits recognized in the quarter for the updated estimate of our provision for the impact of the Tax Act. The effective tax rate for the nine months ended September 30, 2017 was less than the federal statutory rate of 35% primarily due to foreign income taxes at lower rates, the excess tax benefit on share-based compensation, and the release of a valuation allowance.
