Income Taxes

Our effective tax rate was 36.6% and 36.4% for the nine months ended September 30, 2017 and 2016, respectively. Income tax expense during interim periods is based on our estimated annual effective income tax rate plus any discrete items that are recorded in the period in which they occur. Our tax rate is affected by discrete items that may occur in any given year, but may not be consistent from year to year.
