These derivative financial instruments consist primarily of interest rate locks and forward sale commitments. These derivative instruments are recorded on the Consolidated Statements of Financial Condition, as either an asset or liability, at their fair value. Changes in fair value are recognized in noninterest income on the Consolidated Statements of Income. The Company also offers interest rate swaps to some customers through a third-party dealer. These derivatives generally work together as an economic interest rate hedge, but the Company does not designate them for hedge accounting treatment. Consequently, changes in fair value of the corresponding derivative financial asset or liability are recorded as either a charge or credit to current earnings during the period in which the changes occurred, typically resulting in no net earnings impact. </span></p>
