Debt Disclosure [Abstract] |  |  |  |  |
Debt Instrument, Description | In April 2020, we received funds in the amount of approximately $1.6 million pursuant to a loan under the Paycheck Protection Program of the 2020 CARES Act (PPP) administered by the Small Business Administration. The loan has an interest rate of 0.98% and a term of 24 months. Due to an extension of the program, no payments were due until August 2021, although interest accrued during that period. Thereafter, the loan became repayable in monthly installments through April 2022 to retire the loan plus accrued interest. Funds from the loan could only be used for certain purposes, including payroll, benefits, rent and utilities, and a portion of the loan used to pay certain costs was forgivable, all as provided by the terms of the PPP. The CARES Act provided that the forgivable portion of the PPP loan could be reduced if the borrower reduced full-time equivalent employees during the covered period as compared to a base period. As of December 31, 2020, all of the funds received under the PPP had been used for qualified purposes. We applied for and, in July 2021, received partial forgiveness of the loan of approximately $690,000 in accordance with PPP guidelines. The forgiveness was recorded in our financial statements in the third quarter of 2021 as a gain on debt extinguishment. As of December 31, 2021, we have made principal payments totaling $488,000 on the loan. The loan is evidenced by a promissory note, which contains customary events of default relating to, among other things, payment defaults and breaches of representations and warranties. We may prepay the loan at any time prior to maturity with no prepayment penalties. |  |  |  |
