Income Tax Disclosure [Abstract]
Income Taxes	Note 7. Income Taxes The effective tax rate for the three months ended March 31, 2020 and 2021 was (29)%, and 3% respectively. During the year ended December 31, 2020, as a result of a sharp deterioration of business activity related to the COVID-19 pandemic, the Company determined that it was more likely than not that it would be unable to realize its deferred tax assets and recorded a $18.8 million valuation allowance against these assets through an increase to our provision for income taxes. Our effective tax rate for the three months ended March 31, 2021 differs from the statutory tax rate due to the recognition of additional valuation allowance.

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.
