We used net cash in operations of $2,278,334 and $2,706,235 during fiscal years ended September 24, 2022 and September 25, 2021, respectively. At September 24, 2022, we had $6,727 in cash and cash equivalents. On August 4, 2022, Technical Communications Corporation (the "Company") issued an amended and restated demand promissory note in the principal amount of up to $4,000,000 in favor of Carl H. Guild, Jr. Mr. Guild, the Company's Chief Executive Officer, President and Chairman of the Board, loaned the money to the Company to provide working capital. The $4,000,000 consists of $1,000,000 previously loaned to the Company at an interest rate of 6% and $2,000,000 previously loaned to the Company at an interest rate of 7.5% and an additional $1,000,000 at an interest rate of 7.5%. The additional funds will be available to the Company to borrow from Mr. Guild on a revolving basis and the loan has no specified term and may be prepaid at any time without premium or penalty. The outstanding principal balance at September 24, 2022 was $3,000,000, plus accrued interest of $106,000. An interest payment of $30,000 was made in January of 2022.
In December 2022 the Company implemented a partial furlough plan for the majority of salaried employees. Although we have been able to and believe we will continue to be able to retain our employees and maintain all vital functions, it is likely that in a period of continued sustained disruption we would be forced to further furlough or terminate some or all of our employees.
We anticipate that our principal sources of liquidity, including the recent line of credit, will be sufficient to fund our activities through January 2023. We must raise additional capital to pursue our development initiatives, penetrate markets for the sale of our products and continue as a going concern. We cannot provide any assurance that we will be able to raise additional capital. If we are unable to secure additional capital, we may be required to curtail our research and development initiatives and take additional measures to reduce costs in order to conserve cash in amounts sufficient to sustain operations and meet our obligations.
