2018 Activity

In preparation of the joint venture with Primotop described under “Acquisitions” in Note 3, we issued secured debt on August 3, 2018, resulting in gross proceeds of €655 million. Subsequently, on August 31, 2018, the secured debt was contributed along with the related real estate of 71 properties to form the joint venture. Provisions of the secured debt include a term of seven years and a swapped fixed rate of approximately 2.3%.

2017 Activity

On February 1, 2017, we replaced our previous unsecured credit facility with a new revolving credit and term loan agreement (“Credit Facility”). The Credit Facility includes a $1.3 billion unsecured revolving loan facility, a $200 million unsecured term loan facility ($50 million lower than the previous term loan), and a new €200 million unsecured term loan facility.

On March 4, 2017, we redeemed the €200 million aggregate principal amount of our 5.750% Senior Unsecured Notes due 2020.

On March 24, 2017, we completed a €500 million senior unsecured notes offering (“3.325% Senior Unsecured Notes due 2025”). A portion of the proceeds from this offering were used to prepay and extinguish the €200 million term loan facility portion of our Credit Facility on March 30, 2017.

On September 7, 2017, we completed a $1.4 billion senior unsecured notes offering (“5.000% Senior Unsecured Notes due 2027”). We used a portion of the net proceeds from the 5.000% Senior Unsecured Notes due 2027 offering to redeem the $350 million aggregate principal amount of our 6.375% Senior Unsecured Notes due 2022 on October 7, 2017.

Furthermore, the completion of the 5.000% Senior Unsecured Notes due 2027 offering resulted in the cancellation of the $1.0 billion term loan facility commitment from JP Morgan Chase Bank, N.A. that we received to assist in funding the September 2017 Steward transaction. With this commitment, we paid $5.2 million of underwriting and other fees, which we fully expensed upon the cancellation of the commitment.

On September 29, 2017, we prepaid the principal amount of the mortgage loan on our property in Kansas City, Missouri at par in the amount of $12.9 million. To fund such prepayment, including accrued and unpaid interest thereon, we used borrowings from the revolving credit facility portion of our Credit Facility.

With the replacement of our old credit facility, the redemption of the 5.750% Senior Unsecured Notes due 2020, the payoff of our €200 million euro term loan, the cancellation of the $1.0 billion term loan facility commitment, and the payment of our $12.9 million mortgage loan, we incurred a debt refinancing charge of $18.8 million in the first nine months of 2017.

Covenants

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, as defined in the agreements, on a rolling four quarter basis. At September 30, 2018, the dividend restriction was 95% of normalized adjusted funds from operations (“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 September 30, 2018, we were in compliance with all such financial and operating covenants.
