Fair Values of Financial Instruments

The fair values at March 31, 2012 and December 31, 2011 do not reflect subsequent changes in the economy, interest rates, and other variables that may affect the determination of fair value.

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 (Level 1).

2011 Credit Facility - term loan and multicurrency revolving line of credit: The term loan and revolver are not traded publicly. The fair value is calculated using a discounted cash flow model with significant inputs that are corroborated by observable market data, including estimates of incremental borrowing rates for debt with similar terms, maturities, and credit profiles (Level 2). Refer to Note 6 for a further discussion of our debt.

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