(10) Debt

Bank Line of Credit and Term Loan

The Company’s $1.5 billion unsecured revolving line of credit facility (the “Facility”) matures in March 2016 and contains a one-year extension option. Borrowings under the Facility accrue interest at LIBOR plus a margin that depends on the Company’s debt ratings. The Company pays a facility fee on the entire revolving commitment that depends upon its debt ratings. Based on the Company’s debt ratings at September 30, 2013, the margin on the Facility was 1.075%, and the facility fee was 0.175%. 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 September 30, 2013, the Company had $285 million outstanding under the Facility.

On July 30, 2012, the Company entered into a credit agreement with a syndicate of banks for a £137 million ($222 million at September 30, 2013) 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%, (iv) require a minimum Fixed Charge Coverage ratio of 1.5 times and (v) require a formula-determined Minimum Consolidated Tangible Net Worth of $9.2 billion at September 30, 2013. At September 30, 2013, the Company was in compliance with each of these restrictions and requirements of the Facility and Term Loan.

Senior Unsecured Notes

At September 30, 2013, the Company had senior unsecured notes outstanding with an aggregate principal balance of $6.6 billion. At September 30, 2013, interest rates on the notes ranged from 1.22% to 6.98% with a weighted average effective interest rate of 5.10% and a weighted average maturity of five 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 September 30, 2013.

On February 28, 2013, the Company repaid $150 million of maturing 5.625% senior unsecured notes.

On November 19, 2012, the Company issued $800 million of 2.625% senior unsecured notes due in 2020. The notes were priced at 99.7% of the principal amount with an effective yield to maturity of 2.7%; net proceeds from this offering were $793 million.

On July 23, 2012, the Company issued $300 million of 3.15% senior unsecured notes due in 2022. The notes were priced at 98.9% of the principal amount with an effective yield to maturity of 3.3%; net proceeds from the offering were $294 million.

On June 25, 2012, the Company repaid $250 million of maturing 6.45% senior unsecured notes. The notes were repaid with proceeds from the Company’s June 2012 common stock offering.

On January 23, 2012, the Company issued $450 million of 3.75% senior unsecured notes due in 2019. The notes were priced at 99.5% of the principal amount with an effective yield to maturity of 3.8%; net proceeds from the offering were $444 million.

Mortgage Debt

At September 30, 2013, the Company had $1.4 billion in aggregate principal amount of mortgage debt outstanding secured by 132 healthcare facilities (including redevelopment properties) with a carrying value of $2.0 billion. At September 30, 2013, interest rates on the mortgage debt ranged from 0.69% to 8.69% with a weighted average effective interest rate of 6.16% and a weighted average maturity of four 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.

Other Debt

At September 30, 2013, the Company had $78 million of non-interest bearing life care bonds at two of its continuing care retirement communities and non-interest bearing occupancy fee deposits at two of its senior housing facilities, all of which were payable to certain residents of the facilities (collectively, “Life Care Bonds”). The Life Care Bonds are generally refundable to the residents upon the termination of the contract or upon the successful resale of the unit.
