Description of dividend rate percentages												For the first nine quarters after issuance, the dividend rate can range from one percent (1%) to five percent (5%) per annum based upon the increase in QSBL as compared to the baseline. For quarters subsequent to the issuance in 2011, the Company has paid a dividend rate ranging from 3.0% to 5.0%. Based upon an increase in the level of QSBL over the baseline level calculated under the terms of the related purchase agreement, the dividend rate for the first quarter of 2013 is expected to be 1.2% and the dividend rate for the second quarter is expected to be 1.0%, subject to confirmation by Treasury. For the tenth calendar quarter through four and one half years after issuance, the dividend rate will be fixed at between one percent (1%) and seven percent (7%) based upon the level of QSBL compared to the baseline. After four and one half years from the issuance, the dividend rate will increase to nine percent (9%). Subject to regulatory approval, the Company is generally permitted to redeem the Series B preferred shares at par plus unpaid dividends.
