Income Taxes [Abstract]
Income Taxes	Income Taxes Our effective income tax rate was 6% and 24% for the six-month periods ended August 31, 2017 and 2018, respectively. The Company estimates its effective tax rate for the year, which incorporates the reversal of a portion of the valuation allowance, and applies that rate to pre-tax income for the applicable period. This methodology is primarily responsible for the difference between the effective rate and statutory rate, particularly in the prior year, which included the sale of KPWR in Los Angeles and the related reversal of a significant portion of our valuation allowance. Our current year rate is also impacted by the reduction in the Federal Statutory rate from 35% to 21% upon passage of the Tax Cuts and Jobs Act (the "Tax Act").

Our effective income tax rate was 6% and 24% for the six-month periods ended August 31, 2017 and 2018, respectively. The Company estimates its effective tax rate for the year, which incorporates the reversal of a portion of the valuation allowance, and applies that rate to pre-tax income for the applicable period. This methodology is primarily responsible for the difference between the effective rate and statutory rate, particularly in the prior year, which included the sale of KPWR in Los Angeles and the related reversal of a significant portion of our valuation allowance. Our current year rate is also impacted by the reduction in the Federal Statutory rate from 35% to 21% upon passage of the Tax Cuts and Jobs Act (the "Tax Act").

Any further technical corrections or other forms of guidance addressing the Tax Act, as well as regulatory or governmental actions, could result in adjustments to our accounting for the effects of the Tax Act.
