Minimum Regulatory Capital Requirement [Abstract]  
Company's and the bank's actual capital amounts and ratios
As of December 31, 2011, the most recent notifications from the Office of the Comptroller of the Currency categorized the bank as well capitalized under the regulatory framework for prompt corrective action. To be categorized as well capitalized, an institution must maintain minimum total risk-based, Tier 1 risk-based and Tier 1 leverage ratios, as set forth in the following tables. There are no conditions or events since these notifications that management believes have changed the bank's category. The Company's and the bank's actual capital amounts and ratios as of December 31, 2012 and 2011 are also presented in the following tables.
