The Company from time to time enters into derivative financial instruments, including interest rate exchange agreements ("Swaps") and interest rate collar agreements ("Collars"), to manage its exposure to fluctuations in interest rates.

During the year ended December 31, 2008, the Company entered into interest rate derivative transactions in the aggregate notional amount of $550.0 million which were designated as a hedge against the Company's variable rate senior debt. During the period of the hedging relationship, the Company's variable rate debt is expected to be greater than the notional amount of the derivative rate hedging transactions. These transactions are tied to the one-month Eurodollar London Interbank Offered Rate ("LIBOR") interest rate. Under a fixed rate swap, the Company pays a fixed rate on a notional amount to the counter-party, and the counter-party pays to the Company a variable rate on the notional amount equal to the Company's LIBOR borrowing rate. A Collar establishes two separate agreements: an upper limit, or cap, and a lower limit, or floor, for the Company's LIBOR borrowing rate.

During the six months ended June 30, 2011 and 2010, the Company had outstanding the aggregate notional amounts of $225.0 million and $475.0 million, respectively, of interest rate transactions that were hedged against the Company's variable rate senior debt.

The gains and losses were recorded to the statement of comprehensive income (loss) as these derivatives qualified for hedge accounting treatment (see Note 14 for the net change in the fair value). The fair value of these derivatives was determined using observable market-based inputs (a Level 2 measurement as described under Note 17) and the impact of the credit risk on a derivative's fair value (the creditworthiness of the transaction's counterparty for assets and the creditworthiness of the Company for liabilities).

The Company does not expect to reclassify any portion of this amount to the statement of operations over the next twelve months.

The following table presents the accumulated derivative gain (loss) recorded in the statements of other comprehensive income (loss) as of the periods indicated:
