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 six months ended June 30, 2015, our effective tax rate was 38.6%, as compared to 39.0% and 39.6% for the same periods in 2014, respectively.  Our effective tax rates for the three and six months ended June 30, 2014 were impacted by higher state taxes and other discrete tax adjustments.
