The following methods and assumptions were used in estimating fair values:

Cash and cash equivalents: Due to the liquid nature of these instruments, the carrying value approximates fair value.

Term loans: The term loans are not registered with the SEC but are generally transferable through banks that hold the debt and make a market. The fair value is based on quoted prices from recent trades of the term loans.

Convertible senior subordinated notes: The convertible notes are registered with the SEC and are generally transferable. The fair value is based on quoted prices from recent broker trades of the convertible notes. At June 30, 2011, the discount on the liability component was fully amortized. See Note 6 for further discussion.

Derivatives: See Note 7 for a description of our methods and assumptions in determining the fair value of our derivatives, which were determined using fair value measurements of significant other observable inputs (Level 2).
