Regulatory Capital

The Company is subject to the regulatory capital requirements administered by federal banking regulators and the Federal Reserve. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, the Company must meet specific capital guidelines that involve quantitative measures of the Company’s assets, liabilities and certain off-balance sheet items as calculated under regulatory accounting practices. Quantitative measures established by regulation to ensure capital adequacy require the Company to maintain minimum amounts and ratios of total and tier 1 capital to risk-weighted assets, and of tier 1 capital to average assets, as defined in the regulations. As of September 30, 2014 and December 31, 2013, the Company exceeded all capital adequacy requirements to which it is subject.

Actual capital amounts and ratios and selected minimum regulatory thresholds for the Company and its bank subsidiaries, as of September 30, 2014 and December 31, 2013 are presented in the following tables:
