Income Tax Disclosure [Abstract] |
Income Taxes | The Company’s income tax rate for the three and six months ended June 30, 2018 was higher than the U. S. federal statutory rate of 21.0% primarily due to state income taxes and certain expenses that are not deductible for income tax purposes, partially offset by tax benefits resulting from tax deductions from vesting of restricted stock units in excess of book deductions as well as deferred tax benefits from Kentucky House Bill 487 ("HB 487"), which was enacted on April 27, 2018. HB 487 reduces Kentucky’s corporate statutory income tax rate from 6% to 5% and imposes a single-sales factor apportionment effective for the 2018 tax year and beyond. The Company’s income tax rate for the three and six months ended June 30, 2017 was higher than the U.S. federal statutory rate of 35.0% primarily due to state income taxes and certain expenses that are not deductible for income tax purposes, partially offset by tax benefits resulting from tax deductions from vesting of restricted stock units in excess of book deductions.
