The fair value of the Company’s investments in money market funds approximates their face value. Such instruments are classified as Level 1 and are included in Cash and cash equivalents. The fair value of the debt securities consisting of U.S. Treasury bills is based on their quoted market prices and are classified as Level 1. Debt securities purchased with original maturities in excess of three months are included in Marketable securities. The fair value of the equity securities of public companies is based on quoted market prices and are classified as Level 1. Investments in equity securities of public companies are included in Marketable securities. The fair value of the Company’s foreign currency forward contracts is based on foreign currency rates quoted by banks or foreign currency dealers and other public data sources.

The Company utilizes a valuation model to estimate the fair value of the contingent interest derivative on the subordinated convertible debentures due 2037 (“the Subordinated Convertible Debentures”). The inputs to the model include stock price, bond price, risk free interest rates, volatility, and credit spread observations. As several significant inputs are not observable, the overall fair value measurement of the derivative is classified as Level 3. The volatility and credit spread assumptions used in the calculation are the most significant unobservable inputs. As of June 30, 2016, the valuation of the contingent interest derivative assumed a volatility rate of approximately 26% and a credit spread of approximately 6%. The fair value of the contingent interest derivative would not have significantly changed using a volatility rate of either 21% or 31%, or a credit spread of either 5% or 7%.

The following table summarizes the change in the fair value of the Company’s contingent interest derivative on the Subordinated Convertible Debentures during the three and six months ended June 30, 2016 and 2015:

On February 15, 2016, the Company paid contingent interest of $6.5 million in addition to the normal coupon interest to holders of record of the Subordinated Convertible Debentures as of February 1, 2016. In February 2016, the upside trigger on the Subordinated Convertible Debentures was met for the six month interest period ending in August 2016. On August 15, 2016, the Company will pay contingent interest of $6.8 million in addition to the normal coupon interest to holders of record of the Subordinated Convertible Debentures as of August 1, 2016. The $6.8 million contingent interest payable in August 2016 is included in the balance of the contingent interest derivative on the Subordinated Convertible Debentures as of June 30, 2016.

The Company’s other financial instruments include cash, accounts receivable, restricted cash, and accounts payable. As of June 30, 2016, the carrying value of these financial instruments approximated their fair value. The fair value of the Company’s Subordinated Convertible Debentures was $3.1 billion as of June 30, 2016. The fair values of the senior notes due 2023 (the “2023 Senior Notes”) and the senior notes due 2025 (the “2025 Senior Notes”) were $761.3 million and $512.8 million, respectively, as of June 30, 2016. The fair values of these debt instruments are based on available market information from public data sources and are classified as Level 2.
