note 14 financial derivatives we use derivative financial instruments ( derivatives ) primarily to help manage exposure to interest rate , market and credit risk and reduce the effects that changes in interest rates may have on net income , the fair value of assets and liabilities , and cash flows .
we also enter into derivatives with customers to facilitate their risk management activities .
derivatives represent contracts between parties that usually require little or no initial net investment and result in one party delivering cash or another type of asset to the other party based on a notional amount and an underlying as specified in the contract .
derivative transactions are often measured in terms of notional amount , but this amount is generally not exchanged and it is not recorded on the balance sheet .
the notional amount is the basis to which the underlying is applied to determine required payments under the derivative contract .
the underlying is a referenced interest rate ( commonly libor ) , security price , credit spread or other index .
residential and commercial real estate loan commitments associated with loans to be sold also qualify as derivative instruments .
