REGULATORY MATTERS [Abstract] |
REGULATORY MATTERS |
NOTE P: | REGULATORY MATTERS
The Company and the Bank are subject to various regulatory capital requirements administered by federal banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory and possibly additional discretionary actions by regulators that, if undertaken, could have a direct material effect on the Company’s financial statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, the Company and the Bank must meet specific capital guidelines that involve quantitative measures of the Company’s and the Bank’s assets, liabilities, and certain off-balance sheet items as calculated under regulatory accounting practices. The Company’s and the Bank's capital amounts and classification are also subject to qualitative judgments by the regulators about components, risk weightings, and other factors. Management believes, as of December 31, 2017, that the Company and Bank meet all applicable capital adequacy requirements. Basel III Transitional rules became effective for the Company on January 1, 2015 with all of the requirements being phased in over a multi-year schedule, and fully phased in by January 1, 2019. Beginning in 2016, the Company and the Bank are required to maintain a “capital conservation buffer,” composed entirely of common equity Tier 1 capital, in addition to minimum risk-based capital ratios. The required capital conservation buffer is 1.25% for 2017 and 0.625% for 2016. Therefore, to satisfy both the minimum risk-based capital ratios and the capital conservation buffer in 2017, the Company and the Bank must maintain: (i) Common equity Tier 1 capital to total risk-weighted assets of at least 5.75%, (ii) Tier 1 capital to total risk-weighted assets of at least 7.25%, and (iii) Total capital (Tier 1 capital plus Tier 2 capital) to total risk-weighted assets of at least 9.25%. To satisfy both the minimum risk-based capital ratios and the capital conservation buffer in 2016, the Company and the Bank must maintain: (i) Common equity Tier 1 capital to total risk-weighted assets of at least 5.125%, (ii) Tier 1 capital to total risk-weighted assets of at least 6.625%, and (iii) Total capital (Tier 1 capital plus Tier 2 capital) to total risk-weighted assets of at least 8.625%. As of December 31, 2017 and 2016, the amounts, ratios and requirements for the Company are presented below calculated under the Basel III Standardized Transitional Approach. As of December 31, 2017, the OCC categorized the Company and Bank as “well capitalized” under the regulatory framework for prompt corrective action.
