Interest rate contracts The Company has two interest rate swap contracts that the base on its two term loans. The effect of the swaps is to convert the floating base rates on the term loans to fixed rates. Under the swap terms, the Company pays a fixed rate and in return receives a three-month LIBOR rate. The three-month LIBOR rate received on the swaps matches the base rate paid on the term loans since the Company optionally selects a three-month LIBOR rate on the term loans. Both of the interest rate swaps are amortizing swaps such that the notional value of the swaps declines over time and constantly matches the outstanding amounts of the term loans. Including the effect of the interest rate swaps, the annualized interest rates on the original term loan and 2008 term loan were 6.06% and 4.42%, respectively, as of December 31, 2008.

The Company accounts for the swaps as cash flow hedges in accordance with SFAS No. 133, “Accounting for Instruments and Hedging Activities” (“SFAS No. 133”). SFAS No. 133 requires all derivatives, whether designated as hedges or not, to be recorded on the balance sheet at fair value. Since the swaps qualify as cash flow hedges under SFAS No. 133, changes in the fair values of the swaps are recorded in Other comprehensive income as
