Income Taxes	3 Months Ended

Income Tax Disclosure [Abstract]
Income Taxes	The Company’s income tax rate for the three months ended March 31, 2018 was lower than the U. S federal statutory rate of 21.0% primarily due to a $1.2 million tax benefit resulting from tax deductions from vesting restricted stock units in excess of the book deductions that were recognized. This benefit was partially offset by state income taxes and certain expenses that are not deductible for the purposes of income taxes. The Company’s income tax rate for the three months ended March 31, 2017 was lower than the U. S federal statutory rate of 35.0% primarily due to state income tax benefits associated with a revaluation of deferred tax assets due to changes in apportionment and state tax rates.
