2017 Activity

On February 1, 2017, we replaced our unsecured credit facility with a new revolving credit and term loan agreement (“Credit Facility”). The new agreement includes a $1.3 billion unsecured revolving loan facility, a $200 million unsecured term loan facility, and a €200 million unsecured term loan facility. The new unsecured revolving loan facility matures in February 2021 and can be extended for an additional 12 months at our option. The $200 million unsecured term loan facility matures on February 1, 2022, and the €200 million unsecured term loan facility had a maturity date of January 31, 2020; however, it was paid off on March 30, 2017 – see below. The commitment fee on the revolving loan facility is paid at a rate of 0.25%. The term loan and/or revolving loan commitments may be increased in an aggregate amount not to exceed $500 million.

At our election, loans under the Credit Facility may be made as either ABR Loans or Eurodollar Loans. The applicable margin for term loans that are ABR Loans is adjustable on a sliding scale from 0.00% to 0.95% based on our current credit rating. The applicable margin for term loans that are Eurodollar Loans is adjustable on a sliding scale from 0.90% to 1.95% based on our current credit rating. The applicable margin for revolving loans that are ABR Loans is adjustable on a sliding scale from 0.00% to 0.65% based on our current credit rating. The applicable margin for revolving loans that are Eurodollar Loans is adjustable on a sliding scale from 0.875% to 1.65% based on our current credit rating. The commitment fee is adjustable on a sliding scale from 0.125% to 0.30% based on our current credit rating and is payable on the revolving loan facility. At March 31, 2017, the interest rate in effect on our term loan and revolver was 2.49% and 2.24%, respectively.

On March 4, 2017, we redeemed the €200 million aggregate principal amount of our 5.750% Senior Unsecured Notes due 2020 and incurred a redemption premium of approximately $9 million. We funded this redemption, including the premium and accrued interest, with the proceeds of the new euro term loan together with cash on hand.

On March 24, 2017, we completed a €500 million senior unsecured notes offering (“3.325% Senior Unsecured Notes due 2025”). Interest on the notes is payable annually on March 24 of each year. The notes pay interest in cash at a rate of 3.325% per year. The notes mature on March 24, 2025. We may redeem some or all of the 3.325% Senior Unsecured Notes due 2025 at any time. If the notes are redeemed prior to 90 days before maturity, the redemption price will be equal to 100% of their principal amount, plus a make-whole premium, plus accrued and unpaid interest up to, but excluding, the applicable redemption date. Within the period beginning on or after 90 days before maturity, the notes may be redeemed, in whole or in part, at a redemption price equal to 100% of their principal amount, plus accrued and unpaid interest to, but excluding, the applicable redemption date. The 3.325% Senior Unsecured Notes due 2025 are fully and unconditionally guaranteed on a senior unsecured basis by us. In the event of a change of control, each holder of the notes may require us to repurchase some or all of our notes at a repurchase price equal to 101% of the aggregate principal amount of the notes plus accrued and unpaid interest up to, but excluding, the date of the purchase.

On March 30, 2017, we prepaid and extinguished the €200 million of outstanding term loans under the euro term loan facility portion of our Credit Facility. To fund such prepayment, including accrued and unpaid interest thereon, we used part of the proceeds of the 3.325% Senior Unsecured Notes due 2025.

With the replacement of our old credit facility, the redemption of the 5.750% Senior Unsecured Notes due 2020, and the payoff of our €200 million euro term loan, we incurred a debt refinancing charge of approximately $14 million in the 2017 first quarter.

2016 Activity

On February 22, 2016, we completed a $500 million senior unsecured notes offering (“6.375% Senior Unsecured Notes due 2024”). Interest on the notes is payable on March 1 and September 1 of each year. Interest on the notes is paid in cash at a rate of 6.375% per year. The notes mature on March 1, 2024. We may redeem some or all of the notes at any time prior to March 1, 2019 at a “make whole” redemption price. On or after March 1, 2019, we may redeem some or all of the notes at a premium that will decrease over time. In addition, at any time prior to March 1, 2019, we may redeem up to 35% of the notes at a redemption price equal to 106.375% of the aggregate principal amount thereof, plus accrued and unpaid interest thereon, using proceeds from one or more equity offerings. In the event of a change in control, each holder of the notes may require us to repurchase some or all of the notes at a repurchase price equal to 101% of the aggregate principal amount of the notes plus accrued and unpaid interest to the date of purchase.

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 March 31, 2017, the dividend restriction was 95% of normalized adjusted funds from operations (“FFO”). The indentures governing our senior unsecured notes also limit the amount of dividends we can pay based on the sum of 95% of FFO, 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. This 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 March 31, 2017, we were in compliance with all such financial and operating covenants.
