Debt Instruments [Abstract] |
Long-term Debt [Text Block] | Long-Term Debt In December 2021, the Company entered into a credit agreement with a commercial bank and borrowed $40,000. Interest under the term note is payable quarterly over five years. Required quarterly principal payments are $1,250, with the remaining balance due February 2027. The Company may make additional principal payments without penalty. The interest rate is variable at the Wall Street Journal Prime Rate minus 1.00 percent, which totaled 5.75 percent as of December 31, 2025. The Company has an interest rate swap contract that effectively converts $20,000 of the borrowings to a fixed rate of 6.40 percent. See Note 11 for additional information on the interest rate swap. In the event of default, the unaffiliated commercial bank may accelerate payment of the loan. The outstanding principal balance of the loan was $26,250 and $31,250 as of December 31, 2025 and 2024, respectively. The loan is secured by 100 percent of West Bank’s stock. Future required principal payments for long-term debt as of December 31, 2025 are shown in the table below.
