DEBT
    Credit Facility—In August 2022, we and certain of our subsidiaries entered into the Second Amended and Restated Credit Agreement with a syndicate of lenders with the Bank of Montreal, as administrative agent, which provides for a revolving credit facility. The agreement amended our existing revolving credit facility to, among other things, increase the amount available under the facility from $75 million to $150 million, extend the maturity date to August 4, 2027, and transition from LIBOR (London Interbank Offered Rate) to SOFR (Secured Overnight Financing Rate) as a reference rate for borrowings under the credit agreement. Borrowings under the amended credit facility bear interest at SOFR plus an applicable margin of 1.50% to 2.25% per annum, based on our leverage ratio as calculated in accordance with the amended agreement governing the revolving credit facility. Borrowings under the revolving credit facility are secured by substantially all of our current and non-current assets, and the obligations under the credit facility are unconditionally guaranteed by several of our subsidiaries.
    We occasionally borrow and repay amounts under the facility for near-term working capital needs or other purposes and may do so in the future. For the year ended December 31, 2025, we made no borrowings and made no repayments under the facility. For the year ended December 31, 2024, we made no borrowings and made $4.0 million in repayments under the facility. For the year ended December 31, 2023, we made $9.0 million in borrowings and made $5.0 million repayments under the facility. As of December 31, 2025, we had no borrowings outstanding and no outstanding letters of credit under the facility. As of December 31, 2024, we had no borrowings outstanding and no outstanding letters of credit under the facility. As of December 31, 2023, we had $4.0 million in borrowings outstanding and no outstanding letters of credit under the facility. We had $150.0 million available under the facility as of December 31, 2025.
We were in compliance with the applicable covenants under the facility as of December 31, 2025.
    Interest Expense—Interest expense is recorded net of any capitalized interest associated with investments in capital projects. We incurred gross interest expense of $0.8 million, $0.7 million, and $0.8 million for the years ended December 31, 2025, 2024, and 2023, respectively.
    Amounts included in interest expense for the years ended December 31, 2025, 2024, and 2023 (in thousands) are as follows:

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.
