Minimum Regulatory Capital Requirements

12. MINIMUM REGULATORY CAPITAL REQUIREMENTS

Banks and bank holding companies are subject to various regulatory capital requirements administered by federal banking agencies.  Capital adequacy guidelines and, additionally for banks, prompt corrective actions regulations, involve qualitative measures of assets, liabilities, and certain off-balance sheet items calculated under regulatory accounting practices.  Capital amounts and classifications are also subject to qualitative judgement by regulators.  Failure to meet capital requirements can initiate regulatory action.  The final rules implementing Basel Committee on Banking Supervision’s capital guidelines for U.S. banks (Basel III rules) became effective for the Company on January 1, 2016 under BASEL III, community banking institutions must maintain a capital conservation buffer of common equity tier 1 capital in an amount greater than 2.5% of total risk-weighted assets to avoid being subject to limitations on capital distributions and discretionary bonuses. The capital conservation buffer is being phased in over three years with an initial phase-in of 0.625%.

Quantitative measures established by regulation to ensure capital adequacy require the Bancorp and Bank to maintain minimum amounts and ratios (set forth in the following tables) of total and Tier 1 capital to risk weighted assets Tier 1 capital to average assets and common equity Tier 1 capital (all as defined). Management believes, as of December 31, 2016 and 2015, that Randolph Bancorp, Inc. and Randolph Savings Bank met all capital adequacy requirements to which they are subject.

As of December 31, 2016, the most recent notification from the FDIC categorized the Bank as well capitalized under the regulatory framework for prompt corrective action.  To be categorized as well capitalized, the Bank must maintain minimum total risk-based, Tier 1 risk-based, common equity Tier 1 and Tier 1 leverage ratios as set forth in the following tables.  There are no conditions or events since the notification that management believes have changed the Bank’s category.

Bancorp’s and the Bank’s actual and minimum capital amounts and ratios are presented in the following tables.
