In September 2019, the Company entered into a revolving line of credit (LOC) with Massachusetts Business Development Corporation (BDC) in the amount of $2.5 million.  The agreement includes a demand note allowing the Lender to call the loan at any time.  The Company may terminate the agreement without a termination fee after 3 years.  In May of 2020 this credit line was increased to $3.0 million. The LOC is secured by the accounts receivable and other assets of the Company and has an interest rate of LIBOR plus 550 basis points.  The Company is subject to certain financial and non-financial covenants, all of which have been met and/or waived by BDC for 2022.  At December 31, 2022 the Company had $0 borrowings under this LOC and its borrowing base at the time would have permitted an additional $2.9 to have been borrowed.   Total Interest Expense for 2022 was $0 and was $24 thousand for 2021.
