Capital Requirements And Actual Capital Ratios

The tables below illustrate the capital requirements for the Company and the Bank and the actual capital ratios for each entity that exceed these requirements.  The dividends that the Bank pays to the Company are limited to the extent necessary for the Bank to meet the regulatory requirements of a “well-capitalized” bank.  The capital ratios for the Company exceed those for the Bank primarily because the $10 million trust preferred securities offerings that the Company completed in the fourth quarter of 2005 are included in the Company’s capital for regulatory purposes although they are accounted for as a liability in its financial statements.  The trust preferred securities are not included in the Bank's capital ratios.
