Income Tax Provision

(6) Income Tax Provision

For the three and nine months ended September 30, 2016, we had effective income tax rates of 38.9% and 38.2%, respectively, compared to 36.5% and 36.7% for the three and nine months ended September 30, 2015, respectively. The effective income tax rates for the periods presented were different from the statutory United States federal income tax rate of 35% principally due to state income taxes, non-deductible share-based compensation expense, the qualified manufacturing activities deduction, disqualifying incentive stock option dispositions and non-deductible meals and entertainment costs.

We made tax payments of $25.0 million and $27.2 million in the nine months ended September 30, 2016 and September 30, 2015, respectively.
