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. The fair value of the Company’s investments in other debt securities are obtained using the weighted average price of available market prices for the underlying securities from various industry standard data providers, large financial institutions and other third-party sources and are classified as Level 2. 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. 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 December 31, 2013, the valuation of the contingent interest derivative assumed a volatility rate of approximately 25%. 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 December 31, 2013. 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 Subordinated Convertible Debentures during the year ended December 31, 2013 and 2012:



	Year Ended December 31,
	2013		2012

Beginning balance	$	11,203	$	11,625
Unrealized loss (gain) on contingent interest derivative on Subordinated Convertible Debentures	17,801		(422		)
Ending balance	$	29,004	$	11,203

Other

As of December 31, 2013, the Company’s other financial instruments include cash, accounts receivable, restricted cash, and accounts payable whose carrying values approximated their fair values. The fair values of the Company’s Subordinated Convertible Debentures and the Company’s senior notes due 2023 (the “Senior Notes”) as of December 31, 2013, were $2.2 billion and $723.3 million, respectively, and are based on available market information from public data sources. These fair value measurements are classified as Level 2.
