The Company’s long-term debt financing is comprised of certain senior unsecured notes issued to insurance companies in private placement transactions pursuant to note purchase agreements (the Note Purchase Agreements), totaling $311,739,000 as of December 31, 2024. These notes are denominated in U.S. dollars and have fixed interest rates ranging from 2.30 percent to 3.95 percent. The notes had original maturities of seven to 12 years with mandatory principal payments beginning four, five and six years after issuance. The Company will be required to make principal payments on the currently outstanding notes from 2025 to 2032.

On August 27, 2024, the Company entered into amendments to two of its note purchase agreements to increase the available facility amounts and extend the end date of the issuance period to August 27, 2027. The Company’s credit agreement (the Credit Agreement) with a syndicate of banks provides for credit facilities in an initial aggregate principal amount of $450,000,000, consisting of (a) a $350,000,000 multi-currency revolving credit facility and (b) a $100,000,000 delayed draw term loan credit facility, each of which matures on June 24, 2027. The Company's credit agreement with Credit Industriel et Commercial NY (the CIC Credit Agreement) provides for a credit facility in an aggregate principal amount of $8,700,000. The facility is for the sole purpose of the issuance of standby letters of credit. The Company maintains import and export letters of credit, and standby letters of credit under its workers’ compensation insurance agreements and for other purposes, as needed from time to time, which are issued under the Credit Agreement and under the CIC Credit Agreement. As of December 31, 2024, the Company had outstanding letters of credit totaling $4,217,000 and $313,700,000 of outstanding borrowings under the Credit Agreement, inclusive of a $90,000,000 delayed-draw term loan ($10,000,000 of the term loan principal has been permanently repaid as scheduled). There was $122,083,000 available under the Credit Agreement as of December 31, 2024. As of December 31, 2024, the Company had an outstanding letter of credit of $8,694,000 under the CIC Credit Agreement.

Loans under the credit agreement may be incurred, at the discretion of the Company, with terms to maturity of one month, three months or six months. The Company may choose from two interest rate options: (1) Adjusted Term Secured Overnight Financing Rate (SOFR) applicable to USD loans and relevant benchmark rates applicable to EUR, GBP and CAD loans plus spreads ranging from 1.125 percent to 1.750 percent, depending on the Company’s net leverage ratio, or (2) the prime rate plus 0.125 percent to 0.750 percent, depending on the Company’s net leverage ratio. The credit agreement requires the Company to pay a commitment fee ranging from 0.125 percent to 0.250 percent per annum, which also depends on the Company’s net leverage ratio. The credit agreement requires the maintenance of certain financial ratios and compliance with certain other covenants that are similar to the Company’s existing debt agreements, including net worth, interest coverage, leverage financial covenants and limitations on restricted payments, indebtedness and liens.

The Company’s foreign subsidiaries had no debt outstanding at December 31, 2024.

The Company’s material debt agreements contain provisions which, among other covenants, require maintenance of certain financial ratios and place limitations on additional debt, investments and payment of dividends. Based on the loan agreement provisions that place limitations on dividend payments, unrestricted retained earnings (i.e., retained earnings available for dividend distribution) were $251,953,000 and $234,399,000 at December 31, 2024 and 2023, respectively.

Debt at December 31, 2024, matures as follows: $292,807,000 in 2025; $66,786,000 in 2026; $135,535,000 in 2027; $45,000,000 in 2028; $25,000,000 in 2029 and $60,715,000 after 2029. Debt maturing in 2025 includes $69,108,000 of scheduled repayments under long-term debt agreements. The Company’s foreign subsidiaries routinely have short-term working capital loans. These short-term loan agreements could be supplemented, if necessary, by the Company’s $350,000,000 revolving credit facility entered into on June 24, 2022.
