On August 24, 2020, we entered into a financing arrangement consisting of a $50.0 million revolving line of credit secured by substantially all our assets, maturing five years from the closing date, with available borrowings determined by a borrowing base calculation. The revolving line included an option to increase the credit commitment by an additional $15 million.
On March 25, 2022, we amended our secured loan and security agreement, or the Amended Loan and Security Agreement, increasing the revolving line of credit to $75 million, secured by substantially all our assets, maturing in March 2027, with available borrowings determined by a borrowing base calculation.

The applicable margin can range from a minimum of 0.25% to a maximum of 1.75% based on certain conditions as defined in the Amended Loan and Security Agreement. The financing arrangement contains covenants relating to minimum debt service coverage.

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.
