In July 2013, the federal banking agencies issued a final rule revising the regulatory capital rules applicable to most banks and federal savings associations as well as their holding companies generally beginning on January 1, 2015. The rule implements the Basel Committee’s December 2010 framework known as “Basel III” for strengthening the international capital standards as well as certain provisions of the Dodd-Frank Act. The final rule implements a revised definition of regulatory capital, a new common equity Tier 1 minimum capital requirement of 4.5%, and a higher minimum Tier 1 capital requirement of 6.0% (which is an increase from 4.0%). Under the final rule, the total capital ratio remains at 8.0% and the minimum leverage ratio is 4.0%. Additionally, under the final rule, in order to avoid limitations on capital distributions, including dividend payments and certain discretionary bonus payments to executive officers, a banking organization must hold a 2.5% capital conservation buffer composed of common equity Tier 1 capital above its minimum risk-based capital requirements. The buffer is measured relative to risk-weighted assets. The final rule also enhances risk sensitivity and addresses weaknesses identified by the regulators over recent years with the measure of risk-weighted assets. Additionally, the federal banking agencies developed a “Community Bank Leverage Ratio” (the ratio of a bank’s tangible equity capital to average total consolidated assets) for financial institutions with assets of less than $10 billion. A “qualifying community bank” that exceeds this ratio will be deemed to be in compliance with all other capital and leverage requirements, including the capital requirements to be considered “well capitalized” under Prompt Corrective Action statutes. The federal banking agencies may consider a financial institution’s risk profile when evaluating whether it qualifies as a community bank for purposes of the capital ratio requirement. The federal banking agencies must set the minimum capital for the
