The Bank is 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 originate loans, unadvanced funds on loans and standby letters of credit. The instruments involve, to varying degrees, elements of credit risk in excess of the amount recognized in the consolidated balance sheets. The contract amounts of those instruments reflect the extent of involvement the Bank has in particular classes of financial instruments.

The Bank’s exposure to credit loss in the event of nonperformance by the other party to the financial instrument for loan commitments and standby letters of credit is represented by the contractual amounts of those instruments. The Bank uses the same credit policies in making commitments and conditional obligations as it does for on-balance sheet instruments.

Commitments to originate loans are agreements to lend to a customer provided there is no violation of any condition established in the contract. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. Since many of the commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. The Bank evaluates each customer’s creditworthiness on a case-by-case basis. The amount of collateral obtained, if deemed necessary by the Bank upon extension of credit, is based on management’s credit evaluation of the borrower. Collateral held varies, but generally includes secured interests in mortgages.

Standby letters of credit are conditional commitments issued by the Bank to guarantee performance by a customer to a third-party. The credit risk involved in issuing letters of credit is essentially the same as that involved in extending loan facilities to customers.

Notional amounts of financial instruments with off-balance sheet credit risk are approximately as follows as of December 31:

	2021		2020
Unadvanced portions of loans	$	42,781	$	39,817
Commitments to originate loans		15,103		17,451
Standby letters of credit		318		613

In the ordinary course of business, the Company may be subject to various legal proceedings. Management, after consultation with legal counsel, believes that the liabilities, if any, arising from such proceedings will not be material to the consolidated balance sheet or consolidated statements of income.

The Bank has obligations under an operating lease related to a branch. This lease expires in June 2022 and has future lease payments of approximately $16,000. Total lease expense was approximately $32,000 for the years ended December 31, 2021 and 2020.
