Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes For the three months ended March 31, 2019, and 2018, we recorded $3.2 million and $9.8 million, respectively of income tax expense and had an effective rate of 21.9% and 20.9%, respectively. During the three months ended March 31, 2019, and 2018, the primary reason for the difference between the federal statutory income tax rate of 21% and the effective tax rate was the effect of state taxes, offset by excess tax benefits of vested share-based payment awards. During the three months ended March 31, 2019 and 2018, refunds received, net of cash taxes paid were $11.0 million and $12.0 million, respectively.
