Line Of Credit Facility [Abstract]
Revolving Credit Agreement	I. Revolving Credit Agreement On May 12, 2020, MtronPTI and PTI (collectively, the “Borrowers”), both operating subsidiaries of the Company, entered into a loan agreement for a revolving line of credit with Synovus Bank, an unaffiliated entity, as the lender (“Lender”), for up to $3,500,000 (the “Loan Agreement”), such amount to be used for working capital and general operations. The Loan Agreement is evidenced by a promissory note dated May 12, 2020 that matures on May 12, 2022 (the “Note”) and a corresponding security agreement (the “Security Agreement”). The Note bears interest at the London Inter-bank Offered Rate (“LIBOR”) 30-day rate plus 2.50% with a floor of 0.50%. Upon discontinuance or lack of availability of the LIBOR rate, Lender is required to determine a comparable equivalent replacement rate. Accrued interest-only payments are due on a monthly basis until the maturity date. The Borrowers may prepay all or any portion of the loans under the Loan Agreement at any time, without fee, premium or penalty. The Loan Agreement also includes a clean-up provision whereby, during each 12-month period, the outstanding balance must remain at zero for 30 consecutive days. In accordance with the Security Agreement, all property of the Borrowers, both tangible and intangible, will serve as security for borrowings under the Loan Agreement. At December 31, 2021 and 2020, the Company had no outstanding borrowings under its revolving line of credit with Synovus Bank. The Loan Agreement contains various affirmative and negative covenants that are customary for lines of credit and transactions of this type which the Company is in compliance with, including limitations on the incurrence of debt and liabilities by the Borrowers, as well as financial reporting requirements. The Loan Agreement also imposes certain financial covenants based on Debt Service Coverage Ratio and the Ratio of Total Liabilities to Total Net Worth (as such terms are defined in the Loan Agreement). In the event of default, the Lender has the right to terminate its commitment to make loans pursuant to the Loan Agreement and to accelerate the payment on any unpaid principal amount of all outstanding loans and interest thereon.
