The Company's Level 2 interest-rate swap derivative instruments are valued using pricing models based on an income approach that discounts future cash flows to a present value amount. The significant pricing model inputs for the interest-rate swaps include published rates for U.S. Dollar LIBOR interest rate swaps. The pricing model also adjusts for nonperformance risk associated with the counterparty or Company, as applicable, through the use of credit risk adjusted discount rates based on published default rates. The Company did not have any Level 3 instruments measured at fair value at June 30, 2011 or December 31, 2010.

 

The approximate fair value of the Company's cash and cash equivalents, accounts receivable and accounts payable is equal to book value, due to their short-term nature.
