On November 20, 2024, we completed the offering of €700.0 million aggregate principal amount of our 3.518% Euro Notes due December 15, 2032. Interest is payable on these Euro Notes on December 15 of each year until maturity, commencing on December 15, 2025. We received net proceeds of $736.3 million.

On August 15, 2024, we completed the offering of $700.0 million aggregate principal amount of our 5.200% Senior Notes due September 15, 2034. Interest is payable on these Senior Notes on March 15 and September 15 of each year until maturity. We received net proceeds of $700.0 million.

On June 28, 2024, we entered into a new five-year revolving credit agreement (the “2024 Five-Year Credit Agreement”) and a new 364-day revolving credit agreement (the “2024 364-Day Revolving Credit Agreement”), as described below. Borrowings under these credit agreements will be used for general corporate purposes.

The 2024 Five-Year Credit Agreement contains a five-year unsecured revolving facility of $1.5 billion (the “2024 Five-Year Revolving Facility”). The 2024 Five-Year Credit Agreement replaced the previous revolving credit agreement entered into on July 7, 2023 (the “2023 Five-Year Credit Agreement”), which contained a five-year unsecured revolving facility of $1.5 billion (the “2023 Five-Year Revolving Facility”). There were no outstanding borrowings under the 2023 Five-Year Credit Agreement at the time it was terminated.

The 2024 Five-Year Credit Agreement will mature on June 28, 2029, with two one-year extensions exercisable at our discretion and subject to required lender consent. The 2024 Five-Year Credit Agreement also includes an uncommitted incremental feature allowing us to request an increase of the facility by an aggregate amount of up to $500.0 million.

Borrowings under the 2024 Five-Year Credit Agreement bear interest at floating rates, based upon either an adjusted term secured overnight financing rate (“Term SOFR”) for the applicable interest period or an alternate base rate, in each case, plus an applicable margin determined by reference to our senior unsecured long-term debt credit rating. We pay a facility fee on the aggregate amount of the 2024 Five-Year Revolving Facility at a rate determined by reference to our senior unsecured long-term debt credit rating.

The 2024 Five-Year Credit Agreement contains customary affirmative and negative covenants and events of default for unsecured financing arrangements, including, among other things, limitations on consolidations, mergers, and sales of assets. The 2024 Five-Year Credit Agreement also requires us to maintain a consolidated indebtedness to consolidated EBITDA ratio of no greater than 4.5 to 1.0 as of the last day of any period of four consecutive fiscal quarters (with such ratio subject to increase to 5.0 to 1.0 for a period of time in connection with a qualified material acquisition and certain other restrictions). We were in compliance with all covenants under the 2024 Five-Year Credit Agreement as of December 31, 2024. As of December 31, 2024, there were no outstanding borrowings under the 2024 Five-Year Credit Agreement.

The 2024 364-Day Revolving Credit Agreement is an unsecured revolving credit facility in the principal amount of $1.0 billion (the “2024 364-Day Revolving Facility”). The 2024 364-Day Revolving Credit Agreement replaced a credit agreement entered into on July 7, 2023, which was also a 364-day unsecured revolving credit facility of $1.0 billion (the “2023 364-Day Revolving Facility”). There were no borrowings outstanding under the 2023 364-Day Revolving Facility when it was terminated.

The 2024 364-Day Revolving Facility will mature on June 27, 2025. Borrowings under the 2024 364-Day Revolving Credit Agreement bear interest at floating rates based upon either an adjusted Term SOFR for the applicable interest period or an alternate base rate, in each case, plus an applicable margin determined by reference to our senior unsecured long-term debt credit rating. We pay a facility fee on the aggregate amount of the 2024 364-Day Revolving Facility at a rate determined by reference to our senior unsecured long-term debt credit rating.

The 2024 364-Day Revolving Credit Agreement contains customary affirmative and negative covenants and events of default for an unsecured financing arrangement including, among other things, limitations on consolidations, mergers, and sales of assets. The 2024 364-Day Revolving Credit Agreement also requires us to maintain a consolidated indebtedness to consolidated EBITDA ratio of no greater than 4.5 to 1.0 as of the last day of any period of four consecutive fiscal quarters (with such ratio subject to increase to 5.0 to 1.0 in connection with a qualified material acquisition and certain other restrictions). We were in compliance with all covenants under the 2024 364-Day Revolving Credit Agreement as of December 31, 2024. As of December 31, 2024, there were no outstanding borrowings under the 2024 364-Day Revolving Credit Agreement.

On August 28, 2023, we entered into an uncommitted facility letter (the "Uncommitted Credit Facility"), which provides that from time to time, we may request, and the lender in its absolute and sole discretion may provide, short-term loans. Borrowings under the Uncommitted Credit Facility may be used only for general corporate and working capital purposes. The Uncommitted Credit Facility provides that the aggregate principal amount of outstanding borrowings at any time shall not exceed $300.0 million. Each borrowing under the Uncommitted Credit Facility will mature on the maturity date specified by the lender at the time of the advance, which will be no more than 90 days following the date of the advance. The Uncommitted Credit Facility and borrowings thereunder are unsecured. Borrowings under the Uncommitted Credit Facility bear interest at floating rates, based upon either Term SOFR for the applicable interest period, the prime rate, or lender’s cost of funds, in each case, plus an applicable margin determined at the time of each borrowing. The Uncommitted Credit Facility includes customary affirmative and negative covenants and events of default for unsecured uncommitted financing arrangements. We were in compliance with all covenants under the Uncommitted Credit Facility as of December 31, 2024. As of December 31, 2024, there were no outstanding borrowings under the Uncommitted Credit Facility.

Borrowings under our revolving credit facilities have been executed with underlying notes that have maturities of three months or less. At maturity of the underlying note, we elect to either repay the note, borrow the same amount, or some combination thereof. On our consolidated statements of cash flows, we present the borrowings and repayments of these underlying notes as net cash inflows or outflows due to their short-term nature.

The estimated fair value of our senior notes, which includes our Euro notes, as of December 31, 2024, based on quoted prices for the specific securities from transactions in over-the-counter markets (Level 2), was $6,145.2 million.

At December 31, 2024 and 2023, the weighted average interest rate for our borrowings was 3.7 percent and 3.2 percent, respectively. We paid $200.8 million, $200.6 million, and $161.7 million in interest during 2024, 2023, and 2022, respectively.
