Note 3. Income Taxes

Our effective tax rate generally exceeds the federal statutory rate of 35% due to the impact of state taxes and, to a lesser extent, certain other non-deductible items.  For the three and nine months ended September 30, 2015, our effective tax rate was 38.4% and 38.5%, respectively, as compared to 37.1% and 38.7% for the same periods in 2014, respectively.  Our effective tax rate for the three months ended September 30, 2014 was lower due to a reduction in state taxes.
