Bank Line of Credit and Term Loan

On March 31, 2014, the Company amended its unsecured revolving line of credit facility (the “Facility”) with a syndicate of banks, which was scheduled to mature in March 2016, increasing the borrowing capacity by $500 million to $2.0 billion. The amended Facility matures on March 31, 2018, with a one-year committed extension option. Borrowings under the Facility accrue interest at LIBOR plus a margin that depends upon the Company’s debt ratings. The Company pays a facility fee on the entire revolving commitment that depends on its debt ratings. Based on the Company’s debt ratings at March 31, 2014, the margin on the Facility was 0.925%, and the facility fee was 0.15%. The Facility also includes a feature that will allow the Company to increase the borrowing capacity by an aggregate amount of up to $500 million, subject to securing additional commitments from existing lenders or new lending institutions. At March 31, 2014, the Company had no amounts drawn under the Facility.

On July 30, 2012, the Company entered into a credit agreement with a syndicate of banks for a £137 million ($228 million at March 31, 2014) four-year unsecured term loan (the “Term Loan”) that accrues interest at a rate of GBP LIBOR plus 1.20%, based on the Company’s current debt ratings. Concurrent with the closing of the Term Loan, the Company entered into a four-year interest rate swap contract that fixes the interest rate of the Term Loan at 1.81%, subject to adjustments based on the Company’s debt ratings. The Term Loan contains a one-year committed extension option.

The Facility and Term Loan contain certain financial restrictions and other customary requirements, including cross-default provisions to other indebtedness. Among other things, these covenants, using terms defined in the agreements, (i) limit the ratio of Consolidated Total Indebtedness to Consolidated Total Asset Value to 60%, (ii) limit the ratio of Secured Debt to Consolidated Total Asset Value to 30%, (iii) limit the ratio of Unsecured Debt to Consolidated Unencumbered Asset Value to 60% and (iv) require a minimum Fixed Charge Coverage ratio of 1.5 times. The Facility also requires a Minimum Consolidated Tangible Net Worth of $9.5 billion at March 31, 2014. The Term Loan also requires a formula-determined Minimum Consolidated Tangible Net Worth of $9.2 billion at March 31, 2014. At March 31, 2014, the Company was in compliance with each of these restrictions and requirements of the Facility and Term Loan.

Senior Unsecured Notes

At March 31, 2014, the Company had senior unsecured notes outstanding with an aggregate principal balance of $6.9 billion. At March 31, 2014, interest rates on the notes ranged from 1.20% to 6.99% with a weighted average effective interest rate of 5.06% and a weighted average maturity of six years. Discounts and premiums are amortized to interest expense over the term of the related senior unsecured notes. The senior unsecured notes contain certain covenants including limitations on debt, maintenance of unencumbered assets, cross-acceleration provisions and other customary terms. The Company believes it was in compliance with these covenants at March 31, 2014.

On February 12, 2014, the Company issued $350 million of 4.20% senior unsecured notes due 2024. The notes were priced at 99.537% of the principal amount with an effective yield-to-maturity of 4.257%; net proceeds from this offering were $346 million.

On February 1, 2014, the Company repaid $400 million of maturing senior unsecured notes, which accrued interest at a rate of 2.7%. The senior unsecured notes were repaid with a portion of the proceeds from the Company’s November 2013 bond offering.

Mortgage Debt

At March 31, 2014, the Company had $1.2 billion in aggregate principal amount of mortgage debt outstanding secured by 95 healthcare facilities (including redevelopment properties) with a carrying value of $1.5 billion. At March 31, 2014, interest rates on the mortgage debt ranged from 0.69% to 8.69% with a weighted average effective interest rate of 6.19% and a weighted average maturity of three years.

Mortgage debt generally requires monthly principal and interest payments, is collateralized by real estate assets and is generally non-recourse. Mortgage debt typically restricts transfer of the encumbered assets, prohibits additional liens, restricts prepayment, requires payment of real estate taxes, requires maintenance of the assets in good condition, requires maintenance of insurance on the assets and includes conditions to obtain lender consent to enter into or terminate material leases. Some of the mortgage debt is also cross-collateralized by multiple assets and may require tenants or operators to maintain compliance with the applicable leases or operating agreements of such real estate assets.
