12. DEBT AND CREDIT FACILITIES
In June 2018, the Company issued $600.0 million of fixed-rate unsecured senior notes (the “Notes”) due June 15, 2028. Interest is payable semi-annually in arrears, with payments due in June and December of each year. The Company may redeem the Notes, in whole or in part, at any time and from time to time at specified redemption prices. In addition, upon the occurrence of certain change of control triggering events, the Company may be required to repurchase all or a portion of the Notes at a price equal to 101% of their principal amount, plus accrued and unpaid interest. The Notes also include covenants that limit the Company's ability to incur secured indebtedness, enter into sale and leaseback transactions, and consolidate, merge, or transfer all or substantially all of its assets.

The Company has a Five-Year Credit Agreement (the “Credit Agreement”) that provides for a $750.0 million multi-currency unsecured revolving credit facility and matures on July 15, 2027. Subject to certain terms and conditions and the agreement of the lenders, the Company may increase the amount available under the Credit Agreement by up to an additional $250.0 million in the aggregate and extend the maturity date for an additional year. Borrowings under the Credit Agreement bear interest at a variable rate based on the Secured Overnight Financing Rate (“SOFR”), plus a spread ranging from 0.785% to 1.3%, depending on the leverage ratio or credit rating, as defined in the Credit Agreement, plus a 0.1% credit spread adjustment. The Company will also pay a facility fee ranging from 0.09% to 0.20%, depending on the Company's leverage ratio or credit rating, on the entire credit commitment available, whether or not drawn. The facility fee is expensed as incurred. During 2025, under the Credit Agreement, the spread over SOFR was 0.9% and the facility fee was 0.1%. Issuance costs of $2.1 million are
being amortized to interest expense over the term of the Credit Agreement. As of December 31, 2025 and 2024, there were no borrowings outstanding. Amounts outstanding under the Credit Agreement, if any from time to time, are classified as long-term obligations in accordance with the terms of the Credit Agreement. The Credit Agreement is unsecured and contains various financial and other covenants, including a maximum leverage ratio, as defined in the Credit Agreement. The Company was in compliance with all covenants under the Credit Agreement at December 31, 2025.
The weighted-average interest rate under all debt obligations, including the impact of the cross-currency swap contract (for further information, see Note 14), was 3.5% and 3.4% at December 31, 2025 and 2024, respectively.
