Income Tax Disclosure [Abstract]
Income Tax	12. Income Tax On March 27, 2020, the President of the United States signed into law the Coronavirus Aid, Relief and Economic Security Act (“CARES Act”). The CARES Act allows a carryback of net operating losses generated in 2018, 2019 and 2020 to each of the five preceding taxable years. As a result of the carryback, we recognized a tax benefit of $9.7 million due to a partial release of a previously recognized valuation allowance and tax rate change.

The entire disclosure for income taxes. Disclosures may include net deferred tax liability or asset recognized in an enterprise's statement of financial position, net change during the year in the total valuation allowance, approximate tax effect of each type of temporary difference and carryforward that gives rise to a significant portion of deferred tax liabilities and deferred tax assets, utilization of a tax carryback, and tax uncertainties information.
