Income Taxes [Abstract]
Income Taxes	10. Income Taxes At the end of each interim period we are required to estimate our annual effective tax rate for the fiscal year, and use that rate to provide for income taxes for the current year-to-date reporting period. Accordingly, we recorded income tax expense of $3.2 million and $1.8 million for the three months ended March 31, 2015 and 2014, respectively. Our income tax expense for the three months ended March 31, 2015 is based on our estimated annual effective tax rate of approximately 34.5% and certain discreet items, which benefited our effective tax rate by approximately 1.2%.
