__________
The Company is required to make quarterly minimum principal payments totaling $5.0 million annually on the term loan until its maturity date; this amount is included in other current liabilities on the accompanying consolidated balance sheets. Taking into consideration the $5.0 million annual required principal payments, the balance due at maturity will be $466.3 million.
Senior Secured Credit Facility — In March 2024, the Company amended its senior secured credit facility (the "facility") with a 50-basis point reduction in the term loan B ("term loan") interest rate. As a result, borrowings under the term loan bear interest, at the Company's election, at (i) the secured overnight financing rate ("SOFR") plus 1.75 percent, or (ii) the bank's base rate plus 0.75 percent. Related to the debt amendment there were $0.9 million of costs. The Company accounted for the debt amendment as a modification and accordingly, these costs were expensed as incurred. There was an insignificant amount of previously capitalized costs that were written off. Borrowings under the $500.0 million revolving credit facility (the "revolver") bear interest, at the Company's election, at (i) SOFR plus a 10 basis points adjustment plus 2.00 to 3.00 percent, or (ii) the bank's base rate plus 1.00 to 2.00 percent, depending on leverage levels. A commitment fee of 0.30 to 0.45 percent is payable on the undrawn portion of the revolver. The facility is subject to various restrictive covenants including, when amounts are drawn under the revolver, a maximum ratio of senior secured debt to trailing-twelve-months of lender-defined consolidated EBITDA of 3.75 to 1, which was 1.09 to 1 at December 31, 2024. The facility is secured by substantially all of the Company's assets and at December 31, 2024, the Company was in compliance with its debt covenants.
Unsecured Senior Notes — The Company has $550.0 million of unsecured senior notes, due in 2028, which bear interest at 4.625 percent payable semiannually in arrears on May 15 and November 15. These notes are unsecured obligations and are subordinate to the senior secured credit facility. These notes also contain certain customary limitations including, the Company's ability to incur additional indebtedness, engage in mergers and acquisitions, transfer or sell assets, and make certain distributions.
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.
