Regulatory Matters [Abstract]
Regulatory Matters	Regulatory Matters The Bank is subject to a legal limitation on dividends that can be paid to the parent company without prior approval of the applicable regulatory agencies. Arkansas bank regulators have specified that the maximum dividend limit state banks may pay to the parent company without prior approval is 75% of the current year earnings plus 75% of the retained net earnings of the preceding year. Since the Bank is also under supervision of the Federal Reserve, it is further limited if the total of all dividends declared in any calendar year by the Bank exceeds the Bank’s net profits to date for that year combined with its retained net profits for the preceding two years. During the three months ended March 31, 2026, the Company requested approximately $85.6 million in regular dividends from its banking subsidiary. The Company’s banking subsidiary is subject to various regulatory capital requirements administered by the federal banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory and possibly additional discretionary actions by regulators that, 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 must meet specific capital guidelines that involve quantitative measures of the Company’s assets, liabilities and certain off-balance-sheet items as calculated under regulatory accounting practices. The Company’s capital amounts and classifications are also subject to qualitative judgments by the regulators about components, risk weightings and other factors. Furthermore, the Company’s regulators could require adjustments to regulatory capital not reflected in the consolidated financial statements. Quantitative measures established by regulation to ensure capital adequacy require the Company to maintain minimum amounts and ratios of total, Tier 1 common equity Tier 1 ("CET1") and Tier 1 capital (as defined in the regulations) to risk-weighted assets (as defined) and of Tier 1 capital (as defined) to average assets (as defined). Management believes that, as of March 31, 2026, the Company meets all capital adequacy requirements to which it is subject. Basel III became effective for the Company and its bank subsidiary on January 1, 2015. Basel III amended the prompt corrective action rules to incorporate a CET1 requirement and to raise the capital requirements for certain capital categories. In order to be adequately capitalized for purposes of the prompt corrective action rules, a banking organization is required to have at least a 4.5% CET1 risk-based capital ratio, a 4% Tier 1 leverage capital ratio, a 6% Tier 1 risk-based capital ratio and an 8% total risk-based capital ratio. The Federal Reserve Board’s risk-based capital guidelines include the definitions for (1) a well-capitalized institution, (2) an adequately-capitalized institution, and (3) an undercapitalized institution. Under Basel III, the criteria for a well-capitalized institution are: a 6.5% CET1 risk-based capital ratio, a 5% Tier 1 leverage capital ratio, an 8% Tier 1 risk-based capital ratio, and a 10% total risk-based capital ratio. As of March 31, 2026, the Bank met the capital standards for a well-capitalized institution. The Company’s CET1 risk-based capital ratio, Tier 1 leverage capital ratio, Tier 1 risk-based capital ratio, and total risk-based capital ratio were 16.70%, 14.30%, 16.70%, and 19.46%, respectively, as of March 31, 2026.
