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 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 adjusted 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 March 31, 2014, the valuation of the contingent interest derivative assumed a volatility rate of approximately 26%. A hypothetical 5% increase or decrease in the volatility rate would not significantly change the fair value of the contingent interest derivative. The credit spread assumed in the valuation was approximately 4% at March 31, 2014. A hypothetical 1% increase or decrease in the credit spread would not significantly change the fair value of the contingent interest derivative.

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 months ended March 31, 2014 and 2013:

Other

The Company’s other financial instruments include cash, accounts receivable, restricted cash, and accounts payable. As of March 31, 2014, the carrying value of these financial instruments approximated their fair value. The fair values of the Company’s Subordinated Convertible Debentures and the senior notes due 2023 (the “Senior Notes”) as of March 31, 2014, are $2.0 billion and $741.1 million, respectively, and are based on available market information from public data sources. These fair value measurements are classified as Level 2.
