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 to use that rate to provide for income taxes for the current year-to-date reporting period. Our 2020 estimated annual effective tax rate of 23.7% is driven by our blended federal and state statutory rate of 25.4%, and certain other permanent differences between GAAP and tax which decreased our rate by 1.7%. For the three months ended March 31, 2020, our estimated annual rate of 23.7% was impacted by discrete items which had a net impact of decreasing our rate by 0.3%, including excess tax benefits for vested stock-based compensation. For the three months ended March 31, 2020 and 2019, we recorded income tax expense of $8.0 million and $5.9 million, respectively.

The entire disclosure for income taxes.
