Income Taxes	6 Months Ended
Income Taxes	Jun. 30, 2020
Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company applies an estimated annual effective rate to interim period pre-tax income to calculate the income tax provision for the quarter in accordance with the principal method prescribed by the accounting guidance established for computing income taxes in interim periods. Prior to 2020, the Company determined the quarterly income tax provision using a discrete year-to-date calculation. Income tax benefit was $8.6 million and $23.1 million for the three and six months ended June 30, 2020, respectively. The Company’s effective tax rate was 24.7% for the six months ended June 30, 2020. The income tax benefit for the three months ended June 30, 2020 primarily reflects the effect of the reduction of a naked credit (described below). The income tax benefit for the six months ended June 30, 2020 primarily reflects the effects of a change in state taxing jurisdictions and the reduction of a naked credit (described below). In late 2019, the Company moved its headquarters from Minnesota to Texas. This move resulted in a change in the state deferred tax rate from 9.8% to 0%. The tax effect of this move has been recorded as a discrete item during the period. The Company currently records a valuation allowance against its deferred tax assets to the extent there are indefinite lived intangibles related to investments, business interest expense and net operating losses. Due to the uncertain timing of the reversal of these temporary differences, they cannot be considered as a source of future taxable income for purposes of determining a valuation allowance; therefore, the deferred tax liability cannot offset deferred tax assets. This is often referred to as a “naked credit.” Due to a prior deemed ownership change, net operating loss carryforwards are subject to Section 382 of the Internal Revenue Code. We continue to monitor and evaluate the rationale for recording a full valuation allowance for the net amount of the deferred tax assets which are in excess of the indefinite-lived deferred tax assets and liabilities. We intend to continue maintaining a full valuation allowance on these net deferred tax assets until there is sufficient evidence to support the reversal of all or some portion of these allowances. Release of the valuation allowance would result in the recognition of certain deferred tax assets and a decrease to income tax expense for the period the release is recorded. However, the exact timing and amount of the valuation allowance release are subject to change on the basis of the level of profitability that we are able to actually achieve. On March 27, 2020, Congress passed and the President signed into law the Coronavirus Aid, Relief, and Economic Security Act (the “CARES Act”), which included significant changes to U.S. Federal income tax law. However, the only change that is expected to affect the Company is the modification to Section 163(j), which increased the allowable business interest deduction from 30% of adjusted taxable income to 50% of adjusted taxable income.
