REGULATORY REQUIREMENTS |
REGULATORY REQUIREMENTS | NOTE 23—REGULATORY REQUIREMENTS Risk-Based Capital—The Bank is a member bank of the Federal Reserve System and the FRB is the Bank’s primary regulator. The Company and the Bank are subject to various regulatory capital requirements administered by the federal banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory actions by regulators that, if undertaken, could have a direct material effect on the Company’s financial statements. Under capital adequacy guidelines, the Company and the Bank must meet specific capital guidelines that involve quantitative measures of the assets, liabilities and certain off-balance sheet items as calculated under regulatory accounting practices. The capital amounts and classification are also subject to qualitative judgments by the regulators about components, risk weightings and other factors. As of December 31, 2013 and 2012, the Bank is categorized as well capitalized under the regulatory framework for prompt corrective action. To be categorized as well capitalized, the Bank must maintain specific total risk-based, Tier I risk-based, and Tier I leverage ratios as set forth in the table below. There are no conditions or events since December 31, 2013 which management believes have changed the category of the Bank. The actual and required capital amounts and ratios at December 31, 2013 and 2012 are presented as follows:
