On February 12, 2024, we closed and funded an offering of $1,000.0 million of unsecured senior notes in two tranches. The $500.0 million aggregate principal amount of 5.45% Senior Notes is due in 2034 (which we refer to as the 2034 July Notes) and $500.0 million aggregate principal amount of 5.75% Senior Notes is due in 2054 (which we refer to as the 2054 July Notes). The weighted average interest rate is 5.71% per annum after giving effect to underwriting costs and a net hedge loss. During 2023, we entered into a pre-issuance interest rate hedging transaction related to these notes. We realized a net cash loss of approximately $1.4 million on the hedging transactions that will be recognized on a pro rata basis as an increase to our reported interest expense over ten years. We used the proceeds of these offerings to fund acquisitions, earnout payments related to acquisitions and general corporate purposes.
Note Purchase Agreement - During February 2024, we used operating cash to fund the $100.0 million Series HH note maturity that had a fixed rate of 4.72% that was due February 13, 2024 and the $325.0 million Series H note maturity that had a fixed rate of 4.58% that was due February 27, 2024.
Credit Agreement - On June 22, 2023, we entered into a new Credit Agreement (which we refer to as the Credit Agreement) with an administrative agent and a group of other lenders. The Credit Agreement provided for a five-year unsecured revolving credit facility in the amount of $1,200.0 million (including a $75.0 million letter of credit sub-facility), which was also available in Pounds Sterling, Canadian Dollars, Australian Dollars, New Zealand Dollars, Euros, Japanese Yen and any other currencies agreed by the lenders. On November 7, 2023, we entered into the First Amendment to the Credit Agreement, pursuant to which we increased the commitments under the Credit Agreement to $1,700.0 million.
On April 3, 2025, we entered into an amendment and restatement to the Credit Agreement. The Credit Agreement provides for a five-year unsecured revolving credit facility in the amount of $2,500.0 million, which is also available in Pounds Sterling, Canadian Dollars, Australian Dollars, New Zealand Dollars, Euros, Japanese Yen and any other currencies agreed by the lenders. The Credit Agreement also includes a $75.0 million letter of credit sub-facility and a $250.0 million Euro swingline sub-facility. We may also, upon the agreement of either one or more then-existing lenders or of additional banks not currently party to the Credit Agreement, increase the commitments under the Credit Agreement up to $3,000.0 million. The amendment and restatement, among other things, also extended the maturity date from June 22, 2028 to April 3, 2030 and updated the facility fee and applicable margin as determined by reference to the rating of our long-term senior unsecured debt.
We use the Credit Agreement to post letters of credit and to borrow funds to supplement our operating cash flows from time to time. In the three-month period ended March 31, 2025, we had no borrowings or repayments. At March 31, 2025, there were no borrowings outstanding under the Credit Agreement. Due to outstanding letters of credit, $1,697.9 million remained available for potential borrowings under the Credit Agreement at March 31, 2025. Principal uses of the 2024 borrowings under the Credit Agreement were to fund acquisitions, earnout payments related to acquisitions and general corporate purposes.
Premium Financing Debt Facility - On October 30, 2024, we entered into an amendment to our revolving loan facility (which we refer to as the Premium Financing Debt Facility), that provides funding for the three Australian (AU) and New Zealand (NZ) premium finance subsidiaries. The Premium Financing Debt Facility is comprised of: (i) Facility B, which is separated into AU$390.0 million and NZ$25.0 million tranches (the NZ$ tranche has been decreased as of May 1, 2025 to NZ$10.0 million), (ii) Facility C, which is an AU$60.0 million equivalent multi-currency overdraft tranche and (iii) Facility D, which is a NZ$15.0 million equivalent multi-currency overdraft tranche.
At March 31, 2025, AU$230.0 million of borrowings were outstanding under Facility B, with no borrowings outstanding under the NZ$ tranche of Facility B. There were no borrowings outstanding under Facility C and NZ$13.9 million of borrowings were outstanding under Facility D, which in aggregate amount to US$152.8 million of borrowings outstanding under the Premium Financing Debt Facility.
Dividends - Our board of directors determines our dividend policy. Our board of directors determines dividends on our common stock on a quarterly basis after considering our available cash from earnings, our anticipated cash needs and current conditions in the economy and financial markets.
In the three-month period ended March 31, 2025, we declared $167.2 million in cash dividends on our common stock, or $0.65 per common share, an 8% increase over the three-month period ended March 31, 2024. On April 30, 2025, we announced a quarterly dividend for second quarter 2025 of $0.65 per common share. This dividend level in 2025 will result in annualized net cash used by financing activities in 2025 of approximately $664.1 million (based on the number of outstanding shares as of March 31, 2025) or an anticipated increase in cash used of approximately $138.7 million compared to 2024. We make no assurances regarding the amount of any future dividend payments.
