On May 18, 2023, we completed the first phase of the Australia Transaction in which we sold seven of the 11 Australia facilities for A$730 million. We used the proceeds from the first phase of this sale to prepay A$730 million of the A$1.2 billion Australian term loan. As a result of this prepayment, we incurred approximately $0.8 million to accelerate the amortization of related debt issue costs.

On June 29, 2022, we amended our Credit Facility to extend the maturity date of our $1.8 billion revolving facility to June 30, 2026, with our option to extend for an additional 12 months, and extend the maturity date of our $200 million unsecured term loan facility to June 30, 2027. Additionally, we may request incremental term loan and/or revolving loan commitments in an aggregate amount not to exceed $1 billion. As a result of this amendment, we incurred approximately $0.6 million of debt refinancing costs.

On March 15, 2022, we paid off and terminated our $1 billion interim credit facility that was entered into on July 27, 2021 with proceeds from the Macquarie Transaction as more fully described in Note 3 to the condensed consolidated financial statements. As part of this transaction, we incurred approximately $8.8 million of debt refinancing costs.

Our debt facilities impose certain restrictions on us, including restrictions on our ability to: incur debts; create or incur liens; provide guarantees in respect of obligations of any other entity; make redemptions and repurchases of our capital stock; prepay, redeem, or repurchase debt; engage in mergers or consolidations; enter into affiliated transactions; dispose of real estate or other assets; and change our business. In addition, the credit agreements governing our Credit Facility limit the amount of dividends we can pay as a percentage of normalized adjusted funds from operations (“NAFFO”), as defined in the agreements, on a rolling four quarter basis. At June 30, 2023, the dividend restriction was 95% of NAFFO. The indentures governing our senior unsecured notes also limit the amount of dividends we can pay based on the sum of 95% of NAFFO, proceeds of equity issuances, and certain other net cash proceeds. Finally, our senior unsecured notes require us to maintain total unencumbered assets (as defined in the related indenture) of not less than 150% of our unsecured indebtedness.

In addition to these restrictions, the Credit Facility contains customary financial and operating covenants, including covenants relating to our total leverage ratio, fixed charge coverage ratio, secured leverage ratio, consolidated adjusted net worth, unsecured leverage ratio, and unsecured interest coverage ratio. The Credit Facility also contains customary events of default, including among others, nonpayment of principal or interest, material inaccuracy of representations, and failure to comply with our covenants. If an event of default occurs and is continuing under the Credit Facility, the entire outstanding balance may become immediately due and payable. At June 30, 2023, we were in compliance with all such financial and operating covenants.
