For derivative instruments that are designated and qualify as a cash flow hedge, the change in fair value of the derivative instrument is reported as a component of other comprehensive income (loss) and reclassified into earnings in the same period or periods during which the hedged transaction affects earnings. Change in fair value of components excluded from the assessment of effectiveness are recognized in current earnings.

Forward sales commitments that meet the definition of derivative financial instruments under ASC Topic 815, </span><i style="font-style:italic;">Derivatives and Hedging</i><span style="white-space:pre-wrap;">, are carried at their fair value in other assets or other liabilities in the Consolidated Financial Statements.

The Company may offer derivative contracts to its customers in connection with their risk management needs. The Company manages the risk associated with these contracts by entering into an equal and offsetting derivative with a third-party dealer. These derivatives are carried at their fair value in other assets or other liabilities in the Consolidated Financial Statements. Changes in fair value of the corresponding derivative financial asset or liability are recorded in non-interest expense.</span></p>
