LOAN COMMITMENTS AND OTHER RELATED ACTIVITIES LOAN COMMITMENTS AND OTHER RELATED ACTIVITIES
Some financial instruments, such as unfunded loan commitments, credit lines, letters of credit, and overdraft protection, are issued to meet customer financing needs. These are agreements to provide credit or to support the credit of others, as long as conditions established in the contract are met prior to their expiration dates. Commitments may expire without being used. Risk of credit loss exists up to the face amount of these instruments. The same credit policies are used to make such commitments as are used for originating loans, including obtaining collateral at exercise of the commitment.
The following table presents the contractual amount of financial instruments with off-balance-sheet risk as of the periods indicated:
