5. Off-balance sheet financial instruments:

The Company is a party to financial instruments with off-balance sheet risk in the normal course of business to meet the financing needs of its customers. These financial instruments include commitments to extend credit, unused portions of lines of credit and standby letters of credit. Those instruments involve, to varying degrees, elements of credit risk in excess of the amount recognized in the consolidated balance sheets.

The Company’s exposure to credit loss in the event of nonperformance by the other party to the financial instrument for commitments to extend credit, unused portions of lines of credit and standby letters of credit is represented by the contractual amounts of those instruments. The Company follows the same credit policies in making commitments and conditional obligations as it does for on-balance sheet instruments. The Company records a valuation allowance for off-balance sheet credit losses, if deemed necessary, separately as a liability. The allowance is not significant.

The contractual amounts of off-balance sheet commitments at December 31, 2019 and 2018 are summarized as follows:


December 31	2019		2018
Commitments to extend credit	$	290,517	$	294,122
Unused portions of lines of credit		52,168		51,790
Standby letters of credit		45,018		33,275
	$	387,703	$	379,187

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. Since many of the commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. The Company evaluates each customer’s credit worthiness on a case-by-case basis. The amount of collateral obtained, if deemed necessary by the Company upon extension of credit, is based on management’s credit evaluation. Collateral held varies but may include personal or commercial real estate, accounts receivable, inventory and equipment.

Unused portions of lines of credit, including home equity and overdraft protection agreements, are commitments for possible future extensions of credit to existing customers. Unused portions of home equity lines are collateralized and generally have fixed expiration dates. Overdraft protection agreements are uncollateralized and usually do not carry specific maturity dates. Unused portions of lines of credit ultimately may not be drawn upon to the total extent to which the Company is committed.

Standby letters of credit are conditional commitments issued by the Company to guarantee the performance of a customer to a third party. Generally, all standby letters of credit expire within twelve months. The credit risk involved in issuing standby letters of credit is essentially the same as that involved in extending other loan commitments. The Company requires collateral supporting these standby letters of credit as deemed necessary. Collateral supporting standby letters of credit amounted to $31,893 at December 31, 2019 and $22,415 at December 31, 2018. The carrying value of the liability for the Company’s obligations under guarantees for standby letters of credit was not material at December 31, 2019 and 2018.
