Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company’s effective tax rate for the nine months ended September 30, 2021 and 2020 was zero percent. The effective tax rate may vary significantly from period to period and can be influenced by many factors. These factors include, but are not limited to, changes to the statutory rates in the jurisdictions where the Company has operations and changes in the valuation of deferred tax assets and liabilities. The difference between the effective tax rate and the federal statutory rate of 21% primarily relates to certain nondeductible items, state and local income taxes and a full valuation allowance for deferred tax assets.
