Minimum capital requirements

Minimum capital requirements:

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 approaches institutions, the Bank and Company are required to maintain minimum capital ratios as outlined in the table below. Additionally, under U.S. Basel III Capital Rules, the decision was

made to opt out of including accumulated other comprehensive income in regulatory capital. As of December 31, 2021 and 2020, the Bank and Company met all capital adequacy requirements to which they are subject.

In March 2020, the OCC, the Board of Governors of the Federal Reserve System, and the FDIC announced a final rule to delay the estimated impact on regulatory capital stemming from the implementation of CECL. The final rule maintains the three-year transition option in the previous rule and provides banks the option to delay for two years an estimate of CECL’s effect on regulatory capital, relative to the incurred loss methodology’s effect on regulatory capital, followed by a three-year transition period (five-year transition option). The Company adopted the capital transition relief over the permissible five-year period.

Actual and required capital amounts and ratios are included below as of the dates indicated.
