At September 30, 2013, the Company had entered into interest rate swaps with a notional amount of $52.2 billion and interest rate swaptions with a notional amount of $6.8 billion, or 74% of the Company’s Agency mortgage-backed securities and debentures compared to 56% of the Company’s Agency mortgage-backed securities and debentures at June 30, 2013. Changes in the unrealized gains or losses on the interest rate swaps are reflected in the Company’s consolidated statements of comprehensive income (loss). The purpose of the interest rate swaps is to mitigate the risk of rising interest rates that affect the Company’s cost of funds. Since the Company pays a fixed rate and receives a floating rate on the notional amount of the swaps, the intended effect of the swaps is to lock in a cost of financing. As of September 30, 2013, the swap portfolio had a weighted average pay rate of 2.06%, a weighted average receive rate of 0.21% and weighted average maturity of 5.17 years.
