Banks and bank holding companies are subject to regulatory capital requirements administered by federal banking agencies. Capital adequacy guidelines and, additionally for banks, prompt corrective action regulations involve quantitative measures of assets, liabilities, and certain off-balance sheet items calculated under regulatory accounting practices. Capital amounts and classifications are also subject to qualitative judgments by regulators. Failure to meet capital requirements can initiate regulatory action.

Under regulatory guidance for non-advanced approach institutions, the Bank and Company are required to maintain minimum capital ratios as outlined in the table below. Minimum risk-based capital adequacy ratios below include a capital conservation buffer of 2.50%. As of June 30, 2025 and December 31, 2024, the Bank and Company met all capital adequacy requirements to which they are subject. Additionally, under U.S. Basel III Capital Rules, the Bank and Company opted out of including accumulated other comprehensive income in regulatory capital.
