Income Tax Disclosure [Abstract]
Income Taxes	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, 2015, our effective tax rate was 38.6% as compared to 40.6% for the same period in 2014. Our effective tax rate for the three months ended March 31, 2014 was impacted by higher state taxes and other discrete tax adjustments.
