Regulatory Capital Requirements [Abstract]

Regulatory Capital Requirements

Regulatory Capital Requirements

The Company and the Bank are subject to various regulatory capital requirements administered by the 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 material effect on the Company's consolidated 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 Bank's assets, liabilities, and certain off-balance sheet items as calculated under regulatory accounting practices. The capital amounts and the Bank's prompt corrective action classification are also subject to qualitative judgments by the regulators about components, risk-weightings and other factors. Prompt corrective action provisions are not applicable to BHCs such as the Company. The Bank is subject to laws and regulations that limit the amount of dividends it can pay to the Company.

Quantitative measures established by regulation to help ensure capital adequacy require the Company and the Bank to maintain minimum amounts and ratios (set forth in the tables below) of Total and Tier 1 capital (as defined in the regulations) to risk-weighted assets (as defined) and of Tier 1 capital (as defined) to quarterly average assets (as defined). As of December 31, 2015, management believes the capital ratios of the Bank met all regulatory requirements of "well-capitalized" institutions, which are 10% for the Total risk-based capital ratio and 8.0% for the Tier 1 risk-based capital ratio. Furthermore, management believes, as of December 31, 2015 and 2014, that the Company and the Bank met all capital adequacy requirements to which they are subject.

The Company's and the Bank's capital amounts and ratios are presented in the following tables.
