Regulatory Capital Requirements under Banking Regulations [Text Block] Regulatory Capital Requirements
The Company and West Bank are subject to various regulatory capital requirements administered by federal and state banking agencies. Failure to meet minimum capital requirements (as shown in the following table) can result in certain mandatory and possibly additional discretionary actions by regulators which, if undertaken, could have a direct material effect on the Company’s consolidated financial statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, the Company and West Bank must meet specific capital guidelines that involve quantitative measures of their assets, liabilities and certain off-balance-sheet items as calculated under regulatory requirements. The Company’s and West Bank’s capital amounts and classifications are also subject to qualitative judgments by the regulators about components, risk weightings and other factors. Management believed the Company and West Bank met all capital adequacy requirements to which they were subject as of December 31, 2025.
The Company’s and West Bank’s capital ratios are presented in the following table as of December 31, 2025 and 2024.

The Company and West Bank are subject to the rules of the Basel III regulatory capital framework and related Dodd-Frank Wall Street Reform and Consumer Protection Act. The rules include the implementation of a 2.5 percent capital conservation buffer that is added to the minimum requirements for capital adequacy purposes. A banking organization with a conservation buffer of less than the required amount will be subject to limitations on capital distributions, including dividend payments, and certain discretionary bonus payments to executive officers. At December 31, 2025, the capital ratios for the Company and West Bank were sufficient to meet the capital conservation buffer.

The ability of the Company to pay dividends to its stockholders is dependent upon dividends paid by its subsidiary, West Bank. There are currently no additional restrictions on such dividends other than the general restrictions imposed on all Iowa state-chartered banks by applicable law.
The Company’s tangible common equity ratio was 6.42 percent and 5.68 percent at December 31, 2025 and 2024, respectively. The tangible common equity ratio is computed by dividing total equity less preferred stock and intangible assets by total assets less intangible assets. As of December 31, 2025 and 2024, the Company had no intangible assets or preferred stock.
