Note 28 - Supplemental Cash Flow Information >. Note 29 - Financial Instruments With Off-Balance Sheet Risk, Commitments to Extend Credit and Standby Letters of Credit >. Supplemental cash flow information follows: The following table presents a detail of commitments to extend credit and standby letters of credit: The Corporation’s exposure to credit loss in the event of nonperformance by the other party to the financial instrument on commitments to extend credit and standby letters of credit is represented by the contractual amount of those instruments. Management uses the same credit policies in making commitments and conditional obligations as it does for on-bal- ance sheet instruments. Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. These commitments generally expire within one year. Since certain com- mitments are expected to expire without being drawn upon, the total com- mitment amount does not necessarily represent future cash requirements. In the case of credit cards and personal lines of credit, the Corporation can at any time and without cause, cancel the unused credit facility. The amount of collateral, obtained if deemed necessary by the Corporation upon extension of credit, is based on Management’s credit evaluation of the bor- rower. Rates charged on the loans that are finally disbursed is the rate being offered at the time the loans are closed, therefore, no fee is charged on these commitments. The fee is the amount which is used as the esti- mate of the fair value of commitments. In general, commercial and standby letters of credit are issued to facilitate foreign and domestic trade transactions. Normally, commercial and stand- by letters of credit are short-term commitments used to finance commer- cial contracts for the shipment of goods. The collateral for these letters of credit include cash or available commercial lines of credit. The fair value of commercial and standby letters of credit is based on the fees currently charged for such agreements, which at December 31, 2001 is not signifi- cant.
