The carrying value of cash equivalents approximates fair value due to their short-term maturity. The fair value of notes receivable is based on discounting the expected future cash flow streams using yields of the underlying credit. The fair value of long-term debt is estimated using quoted market prices or indices for similar liabilities and taking into consideration other factors such as credit quality and maturity. The carrying value and fair value of the guarantee of the equity method investee's debt represents the amount the Company expects to pay to settle this obligation. The fair value of the letters of credit and surety bond are based on the present value of the costs associated with maintaining these instruments over their expected term. See Note 2 for discussion of the fair value of marketable securities and long-term marketable equity securities, Note 9 for discussion of the fair value of the auction rate securities and Note 5 for discussion of the fair value of the contingent consideration arrangement related to the OkCupid acquisition.
