In preparing financial statements, management is required to make estimates and assumptions that affect the reported amount of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the financial statements. In addition, these estimates and assumptions affect revenues and expenses in the financial statements and as such, actual results could differ from those estimates.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;">Material estimates that are particularly susceptible to change include: (1) the allowance for loan losses, (2) fair values of debt securities based on estimates from independent valuation services or from brokers and (3) assessment of goodwill for possible impairment.</p>

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 from Covenant (acquired by the Corporation) into fixed interest rate exposures. Those interest rate swaps have been simultaneously economically hedged by offsetting interest rate swaps that Covenant had in place with a third party (assumed by the Corporation), 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>
