Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The income tax benefit for the three and nine month periods ended September 30, 2020 was calculated using a discrete approach. This methodology was used because changes in the Company's results of operations and non-deductible expenses can materially impact the estimated annual effective tax rate. For the three months ended September 30, 2020, the Company's income tax benefit was $7.7 million on a pre-tax loss of $27.6 million, which includes certain non-deductible expenses and discrete tax benefits. This compares to an income tax benefit of $6.2 million on a pre-tax loss of $38.1 million, which includes certain non-deductible expenses, for the three months ended September 30, 2019. For the nine months ended September 30, 2020, the Company's income tax benefit was $54.1 million on a pre-tax loss of $503.7 million, which included non-cash goodwill charges (approximately $313.1 million) and other expenses that are not deductible for income tax purposes. The impact of these non-deductible expenses was partially offset by a $16.4 million discrete tax benefit related to the carryback of U.S. net operating losses under the Coronavirus Aid, Relief, and Economic Security ("CARES") Act. This compares to an income tax benefit of $6.7 million on a pre-tax loss of $63.0 million, which includes certain non-deductible expenses, for the nine months ended September 30, 2019.
