Four Seasons Health Care Senior Unsecured Notes

On June 28, 2012, the Company purchased senior unsecured notes with an aggregate par value of £138.5 million at a discount for £136.8 million (par value of $237 million). The notes were issued by Elli Investments Limited, a subsidiary of Terra Firma, a European private equity firm, as part of its financing for the acquisition of Four Seasons Health Care (“Four Seasons”), an elderly and specialist care provider in the UK. The notes mature in June 2020 and are non-callable through June 2016. The notes bear interest on their par value at a fixed rate of 12.25% per annum, with an original issue discount resulting in a yield to maturity of 12.5%. This investment was financed by a GBP denominated unsecured term loan that is discussed in Note 10. These senior unsecured notes are accounted for as marketable debt securities and classified as held-to-maturity.
