Regulatory Capital
Regulatory Capital

The Company and its subsidiary Bank are subject to regulatory capital requirements promulgated by the federal banking agencies. The Federal Reserve establishes capital requirements, including well capitalized standards, for the consolidated financial holding company, and the OCC has similar requirements for the Company's subsidiary bank. 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 consolidated statements of financial condition.

Federal regulators require federally insured depository institutions to meet several minimum capital standards: (1) total capital to risk-weighted assets of 8.0%; (2) tier 1 capital to risk-weighted assets of 6.0%; (3) common equity tier 1 capital to risk-weighted assets of 4.5%; and (4) tier 1 capital to adjusted total assets of 4.0%. In addition to establishing the minimum regulatory capital requirements,

the regulations limit capital distributions and certain discretionary bonus payments to management if the institution does not hold a "capital conservation buffer" consisting of 2.5% of common equity tier 1 capital to risk-weighted assets above the amount necessary to meet its minimum risk-based capital requirements. The capital conservation buffer requirement was phased in beginning January 1, 2016, at 0.625% of risk-weighted assets and increased each year until it was fully implemented at 2.5% on January 1, 2019. The regulators established a framework for the classification of savings institutions into five categories: well capitalized, adequately capitalized, undercapitalized, significantly undercapitalized, and critically undercapitalized. Generally, an institution is considered well capitalized if it has: a total capital to risk-weighted assets ratio of at least 10.0%, a tier 1 capital to risk-weighted assets ratio of at least 8.0%, a common tier 1 capital to risk-weighted assets ratio of at least 6.5%, and a tier 1 capital to adjusted total assets ratio of at least 5.0%. As of December 31, 2018 and 2017, the Company and the Bank exceeded all capital adequacy requirements to which it is subject.
    
Based upon most recent notification from federal banking regulators, the Bank was categorized as well capitalized as of September 30, 2018, under the regulatory framework for prompt corrective action. There are no conditions existing or events which have occurred since notification that management believes have changed the Bank's category.

The following table presents the Company's and the Bank's actual capital amounts and ratios as of December 31, 2018 and 2017 as compared to the Federal Reserve Bank minimum capital adequacy requirements and the Federal Reserve Bank requirements for classification as a well-capitalized institution:
