Junior Subordinated Debenture Owed to Unconsolidated Subsidiary Trust [Abstract] |
Subordinated Borrowings [Text Block] | Subordinated Notes In July 2003, the Company issued $20,619 in junior subordinated debentures to the Company’s subsidiary trust, West Bancorporation Capital Trust I. The junior subordinated debentures are senior to the Company’s common stock. As a result, the Company must make payments on the junior subordinated debentures (and the related trust preferred securities) before any dividends can be paid on its common stock, and, in the event of the Company’s bankruptcy, dissolution or liquidation, the holders of the debentures must be satisfied before any distribution can be made to the holders of the common stock. The Company has the right to defer distributions on the junior subordinated debentures (and the related trust preferred securities) for up to five years, during which time no dividends may be paid to holders of the Company’s common stock. The junior subordinated debentures have a 30-year term, do not require any principal amortization, and are callable at the issuer’s option. The interest rate is a variable rate based on the 3-month term Secured Overnight Financing Rate (SOFR) plus 0.26161 percent tenor spread adjustment plus 3.05 percent. At December 31, 2025, the interest rate was 7.00 percent. Interest is payable quarterly, unless deferred. The Company has never deferred an interest payment. The effective cost of the junior subordinated debentures at December 31, 2025, including amortization of issuance costs, was 7.06 percent. Holders of the trust preferred securities associated with the junior subordinated debentures have no voting rights, are unsecured, and rank junior in priority to all the Company’s indebtedness and senior to the Company’s common stock. The junior subordinated debentures were reported net of unamortized debt issuance costs of $101 and $114 as of December 31, 2025 and 2024, respectively. The Company has an interest rate swap contract that effectively converts $20,000 of the variable-rate junior subordinated debentures to a fixed rate of 4.81 percent. See Note 11 for additional information on the interest rate swap. In addition, the junior subordinated debentures qualify as additional Tier 1 capital of the Company for regulatory purposes. In June 2022, the Company issued $60,000 of subordinated notes (the Notes). The Notes initially bear interest at 5.25 percent, with interest payable semi-annually for the first five years of the Notes. Beginning in June 2027, the interest rate will be reset quarterly to a floating rate that is expected to be three-month term SOFR plus 2.41 percent with payments due quarterly. The Company may redeem the Notes, in whole or in part, on or after June 15, 2027 at a price equal to 100 percent of the principal amount of the Notes being redeemed plus accrued and unpaid interest. The Notes will mature on June 15, 2032 if they are not earlier redeemed. The Notes were reported net of unamortized debt issuance costs of $363 and $612 as of December 31, 2025 and 2024, respectively.
