F. CNB Loan

On December 31, 2016, MtronPTI renewed its Loan Agreement (the "CNB Loan Agreement") with City National Bank of Florida ("City National"). The CNB Loan Agreement provided for a revolving line of credit in the amount of $3.0 million (the "CNB Revolver"), bearing interest at a variable rate equal to 30-day LIBOR plus 200 basis points to be set on the first day of each month, expiring on September 30, 2018. The CNB Loan Agreement also provided that MtronPTI will pay City National a fee equal to 0.75% per year on the daily unused amount. The Company's obligations under the CNB Loan Agreement were secured only by cash collateral and did not require any other liens.

At December 31, 2017, there was no balance outstanding under the CNB Revolver. The CNB Revolver expired September 30, 2018.

About Debt Disclosures

Debt disclosures detail a company's borrowing structure — the types of instruments, interest rates, maturity schedule, and covenant restrictions that define its financial obligations and flexibility. This section is essential for assessing refinancing risk, interest rate exposure, and the margin of safety against financial distress.

Key signals: the maturity schedule reveals concentration risk — large maturities within 1-2 years during tight credit markets can force dilutive refinancing or asset sales. Compare the fair value of debt against carrying amount to gauge whether the market views the company's credit risk differently than the balance sheet suggests. Watch covenant compliance disclosures for tightening cushions, especially leverage and interest coverage ratios. Variable-rate debt exposure quantifies sensitivity to interest rate changes. Secured versus unsecured mix affects recovery rates and future borrowing capacity. Compare net debt-to-EBITDA against industry peers and covenant limits to assess financial health.
