Unusual or Infrequent Items, or Both, Disclosure [Text Block]	*NOTE 20.* PAYCHECK PROTECTION PROGRAM** On May 6, 2020, the Company received loan proceeds in the amount of $0.9 million from Wells Fargo Bank, N.A. (the “PPP Loan”) pursuant to the Paycheck Protection Program (“PPP”) under the Coronavirus Aid, Relief and Economic Security Act (the “CARES Act”), which was enacted on March 27, 2020. The terms of the PPP Loan were subsequently revised in accordance with the provisions of the Paycheck Protection Flexibility Act of 2020, or the PPP Flexibility Act, which was enacted on September 5, 2020. The PPP loan provided for an interest rate of 1.00% per year and maturity two years after the date of initial disbursement, with initial principal and interest payments coming due late in fiscal 2021. The PPP Loan could be prepaid by the Company at any time prior to the maturity with no prepayment penalties. Funds from the PPP Loan could only be used for payroll costs, costs used to continue group health care benefits, rent and utilities incurred during the 24-week period after receiving the PPP Loan (collectively, “Qualifying Expenses”) in order for the PPP Loan to be forgiven in whole or in part. The Company used the entire PPP Loan amount for Qualifying Expenses. Since the Company determined that there was reasonable assurance that it would meet the conditions for forgiveness of the full loan amount, the Company accounted for the forgivable PPP Loan as a government income grant that we earned through the Company’s compliance with the loan forgiveness criteria. A deferred income liability was recognized upon receipt of the forgivable loan proceeds. The deferred income liability was recognized as other income as Qualifying Expenses were incurred. For the year ended December 31, 2020, $0.9 million, was recognized as other income and recorded in the consolidated statements of operations and comprehensive loss. No amount was recognized for the year ended December 31, 2021. The Company received notice, dated May 24, 2021, from Wells Fargo Bank, N.A. confirming the full loan amount of $0.9 million was forgiven.
