These financial instruments consist of interest rate swap agreements which contain master netting and collateral provisions designed to protect the party at risk. Interest rate swaps with commercial banking customers were executed to facilitate their respective risk management strategies. Under the terms of these arrangements, the commercial banking customers effectively exchanged their floating interest rate exposures on loans into fixed interest rate exposures. Those interest rate swaps have been simultaneously economically hedged by offsetting interest rate swaps with a third party such that the Corporation has effectively exchanged its fixed interest rate exposures for floating rate exposures. These derivatives are not designated as hedges and are not speculative. Rather, these derivatives result from a service provided to certain customers. As the interest rate swaps associated with this program do not meet the hedge accounting requirements, changes in the fair value of both the customer swaps and the offsetting swaps are recognized directly in earnings. Interest differentials paid or received under the swap agreements are reflected as adjustments to interest and fees on loans. The notional amounts of the interest rate swaps are not exchanged and do not represent exposure to credit loss. The fair value of interest rate derivatives is included in the balance of other assets and other liabilities in the consolidated balance sheets.</p>
