Regulatory Capital Requirements [Abstract]  
Regulatory Capital Requirements
Regulatory Capital Requirements
The Company (on a consolidated basis) and its banking subsidiary 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 direct material effect on the Company and its subsidiary's financial statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, the Company and its banking subsidiary must meet specific capital guidelines that involve quantitative measures of assets, liabilities, and certain off-balance sheet items as calculated under regulatory accounting practices. The capital amounts and 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 bank holding companies.
Quantitative measures established by regulation to ensure capital adequacy require the Company and its banking subsidiary to maintain minimum amounts and ratios (set forth in the following table) of total and Tier 1 capital to risk-weighted assets (as defined in the regulations) and of Tier 1 capital to average assets (as defined in the regulations). Management believes, as of December 31, 2011 and 2010, that the Company and Columbia Bank met all capital adequacy requirements to which they are subject.
As of December 31, 2011, the most recent notification from the Federal Deposit Insurance Corporation categorized Columbia 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 the notification that management believes have changed Columbia Bank’s category. The Company and its banking subsidiary’s actual capital amounts and ratios as of December 31, 2011 and 2010, are also presented in the following table.
