CNB evaluates each customer's creditworthiness and related collateral on a case-by-case basis.The amount of collateral obtained if deemed necessary by CNB upon extension of credit is based on management's credit evaluation of the customer.Collateral held varies but may include accounts receivable, inventory, real estate, equipment and income-producing commercial properties.Standby letters of credit written are conditional commitments issued by CNB to guarantee the performance of a customer to a third party.Those guarantees are issued to support public and private borrowing arrangements, bond financing and similar transactions.The credit risk involved in issuing a letter of credit is essentially the same as that involved in extending loan facilities to customers.A summary of off-balance sheet instruments as of December 31 is as follows:39"
