​ 1 Amounts are shown inclusive of a capital conservation buffer of 2.50%. Under the Federal Reserve’s Small Bank Holding Company Policy Statement, the Company is not subject to the minimum capital adequacy and capital conservation buffer capital requirements at the holding company level, unless otherwise advised by the Federal Reserve (such capital requirements are applicable only at the Bank level). Although the minimum regulatory capital requirements are not applicable to the Company, we calculate these ratios for our own planning and monitoring purposes. 2 The prompt corrective action provisions are only applicable at the Bank level. The Bank exceeded the general minimum regulatory requirements to be considered “well capitalized.”
