Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes: The Company’s effective tax rate for the three and six months ended June 30, 2018 was 17.03% and 17.50%, compared to the effective tax rate for the three and six months ended June 30, 2017 of 28.80% and 30.59%. The effective tax rate for the three and six months ended June 30, 2018 is lower than the effective tax rate for the three and six months ended June 30, 2017 primarily due to the impact of tax reform lowering the U.S. tax rate from 35.0% to 21.0%, as well as the impact of greater tax benefits from equity compensation in the current period versus the prior period. The difference between statutory tax rates and the Company’s effective tax rate is primarily due to tax benefits attributable to equity compensation, offset by additional state and local income taxes.
