Four Seasons Health Care Senior Unsecured Notes

Marketable debt securities, net are classified as held-to-maturity debt securities and primarily represent senior notes issued by Elli Investments Limited (“Elli”), a company beneficially owned by funds or limited partnerships managed by Terra Firma, as part of the financing for Elli’s acquisition of Four Seasons Health Care (the “Four Seasons Notes”). The Four Seasons Notes mature in June 2020, are non-callable through June 2016 and bear interest on their par value at a fixed rate of 12.25% per annum. The Company purchased an aggregate par value of £138.5 million of the Four Seasons Notes at a discount for £136.8 million ($215 million) in June 2012, representing 79% of the total £175 million issued and outstanding Four Seasons Notes. In June 2015 and September 2015, the Company determined that the Four Seasons Notes were other-than-temporarily impaired and recorded impairment charges of $42 million and $70 million, respectively. Elli remains obligated to repay the aggregate par value at maturity and interest payments due June 15 and December 15 each year. When the remaining semi-annual interest payments are received, the Company expects to reduce the carrying value of the Four Seasons Notes during the related fiscal period. In December 2015, the Company received its contractual interest payment of £8 million ($13 million), which was applied against the principal balance reducing the carrying amount to £58 million ($85 million and $83 million at December 31, 2015 and March 31, 2016, respectively).
