Regulatory Capital Requirements [Abstract]

Regulatory Capital Requirements

(10) Regulatory Capital Requirements

Banks and bank holding companies are subject to regulatory capital requirements administered by federal banking agencies.  Capital adequacy regulations and, additionally for banks, the 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 result in 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, 2015 with full compliance with all of the requirements being phased in over a multi-year schedule, and became fully phased in on January 1, 2019.  The capital rules include a capital conservation buffer that is designed to absorb losses during periods of economic stress and to require increased capital levels before capital distributions and certain other payments can be made.  Failure to meet the full amount of the buffer will result in restrictions on the Company’s ability to make capital distributions, including dividend payments and stock repurchases, and to pay discretionary bonuses to executive officers.  The buffer was fully implemented at 2.5% as of January 1, 2019.  Management believes, as of March 31, 2019, the Company and Bank meet all capital adequacy requirements to which they are subject.

Prompt corrective action regulations provide five classifications:  well capitalized, adequately capitalized, undercapitalized, significantly undercapitalized, and critically undercapitalized, although these terms are not used to represent overall financial condition.  If a bank is not classified as well capitalized, regulatory approval is required to accept brokered deposits.  If a bank is undercapitalized, capital distributions are limited, as is asset growth and expansion, and capital restoration plans are required.  The federal banking agencies are required to take certain supervisory actions (and may take additional discretionary actions) with respect to an undercapitalized institution or its holding company.  Such actions could have a direct material effect on an institution’s or its holding company’s financial statements.  As of March 31, 2019 and December 31, 2018, the most recent regulatory notifications categorized the Bank as well capitalized under the regulatory framework for prompt corrective action.  There are no conditions or events since that notification that management believes have changed the Bank’s category.

The Bank and the Company reported the following capital ratios as of March 31, 2019 and December 31, 2018:
