Credit Facilities
The Company has a $3.5 billion multi-currency unsecured five-year revolving credit facility (the "Credit Facility") expiring October 2028. Borrowings under the Credit Facility bear interest at a rate per annum equal, at the Company's option, either at (a) the Secured Overnight Financing Rate ("SOFR") benchmark rate for U.S. dollar borrowings, or (b) a currency specific benchmark rate, plus an applicable margin which varies with the Company's credit ratings. The Company is required to maintain certain coverage and leverage ratios for the Credit Facility, which are evaluated quarterly.
The Credit Facility includes provisions for determining a benchmark replacement rate in the event existing benchmark rates are no longer available or in certain other circumstances, in which an alternative rate may be required. At December 31, 2025 and 2024, the Company had no borrowings under this facility.
The Company also maintains other credit and overdraft facilities with various financial institutions aggregating $122 million at December 31, 2025 and $123 million at December 31, 2024. There were no outstanding borrowings under these facilities at December 31, 2025 and 2024.
The Company has outstanding guarantees and letters of credit with various banks aggregating $150 million and $163 million at December 31, 2025 and 2024, respectively.

Fair Value of Short-term and Long-term Debt
The estimated fair value of the Company’s short-term and long-term debt is provided below. Certain estimates and judgments were required to develop the fair value amounts. The fair value amounts shown in the following table are not necessarily indicative of the amounts that the Company would realize upon disposition, nor do they indicate the Company’s intent or need to dispose of the financial instrument.
| December 31, 2025 | December 31, 2024 | |||||||||||||||||||||||||
| (In millions) | Carrying Amount | Fair Value | Carrying Amount | Fair Value | ||||||||||||||||||||||
| Short-term debt | $ | 1,267 | $ | 1,261 | $ | 519 | $ | 518 | ||||||||||||||||||
| Long-term debt | $ | 18,320 | $ | 18,093 | $ | 19,428 | $ | 18,734 | ||||||||||||||||||
The fair value of the Company’s short-term debt consists of term debt maturing within the next year and its fair value approximates its carrying value. The estimated fair value of a primary portion of the Company's long-term debt is based on discounted future cash flows using current interest rates available for debt with similar terms and remaining maturities. Short- and long-term debt would be classified as Level 2 in the fair value hierarchy.

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.
