Commitments and Contingencies [Text Block] Commitments and Contingencies
Financial instruments with off-balance-sheet risk: The Company 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 extend credit and standby letters of credit. These 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 and standby letters of credit is represented by the contractual amount of those instruments. The Company uses the same credit policies in making commitments and conditional obligations that it uses for on-balance-sheet instruments. The Company's commitments consisted of the following amounts as of June 30, 2026 and December 31, 2025.

West Bank previously executed Mortgage Partnership Finance (MPF) Master Commitments (Commitments) with the FHLB of Des Moines to deliver residential mortgage loans and to guarantee the payment of any realized losses that exceed the FHLB's first loss account for mortgages delivered under the Commitments. West Bank receives credit enhancement fees from the FHLB for providing this guarantee and continuing to assist with managing the credit risk of the MPF Program residential mortgage loans. The total outstanding balance of mortgage loans sold under the MPF Program was $12,993 and $14,411 at June 30, 2026 and December 31, 2025, respectively.

Concentrations of credit risk: Substantially all of the Company's loans, commitments to extend credit and standby letters of credit have been granted to customers in the Company's market areas. The concentrations of credit by type of loan are set forth in Note 4. The distribution by type of loan of commitments to extend credit approximates the distribution by type of loan outstanding. Standby letters of credit were granted primarily to commercial borrowers.
Contingencies: Neither the Company nor West Bank is a party, and no property of these entities is subject, to any material pending legal proceedings, other than ordinary routine litigation incidental to West Bank's business. The Company does not know of any proceeding contemplated by a governmental authority against the Company or West Bank.
