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 months ended March 31, 2014, our effective tax rate was 40.6% as compared to 36.1% for the same period in 2013. The increase in our effective tax rate was due to the expiration of favorable tax credits for the use of alternative fuels provided by the American Taxpayer Relief Act of 2012 enacted in the first quarter of 2013 and other discrete tax adjustments for the three months ended March 31, 2014.
