Long-term Debt [Text Block]	9. PAYMENT PROTECTION PROGRAM On April 21, 2020, the Company entered into a promissory note and received a Paycheck Protection Program loan “PPP Loan” from the Small Business Association “SBA”, which was established under the CARES Act. The Company received net proceeds of $646,000 from the PPP Loan. The term of the PPP Loan is two years with an interest rate of 1.00% per annum, which was deferred for the first six months of the term of the loan or after an application is filed for loan forgiveness, whichever is later. Each monthly payment shall be in the amount which would fully amortize the principal balance outstanding under the PPP Loan. Pursuant to the terms of the CARES Act, the proceeds of the PPP Loan may be used for payroll costs, mortgage interest, rent or utility costs. The promissory note of the PPP Loan contains customary events of default relating to, among other things, payment defaults, breach of representations and warranties, or provisions of the promissory note. The occurrence of an event of default may result in a claim for the immediate repayment of the amount outstanding under the PPP Loan. In late December 2020, the Company applied with the SBA for forgiveness of the PPP Loan and was notified on March 30, 2021 that the SBA had approved our application to forgive the entire amount of the loan and accrued interest. For the six months ended June 30, 2021, the Company recorded a gain on extinguishment of debt of $652,000 representing the principal and accrued interest for the PPP Loan at the time of forgiveness.
