At December 31, 2013 preferred stock consisted solely of Series F Non-Cumulative Perpetual Preferred Stock. Series E Non-Cumulative Convertible Perpetual Preferred Stock (“Series E Preferred Stock”): The Series E Preferred Stock, originally issued on June 30, 2010, carried a stated dividend rate of 7.00% and was perpetually convertible by the holder into shares of common stock at a per share conversion price of $12.15, subject to anti-dilution adjustments upon the occurrence of certain events. In addition, the Company could exercise a conversion option on or after the third anniversary of the issue date (June 30, 2013), at the same $12.15 conversion price if the Company’s common stock price equals or exceeds $17.22 for at least 20 trading days in a period of 30 consecutive trading days. The Series E Preferred Stock was not registered under the Securities Act of 1933, as amended (the “Act”), and was issued pursuant to an exemption from registration under Regulation D of the rules promulgated under the Act. The Series E Preferred Stock was intended to qualify as Tier 1 capital of the Company for regulatory purposes. The Company used the net proceeds from the issuance to further strengthen its capital and liquidity positions. Pursuant to the terms of the Series E Preferred Stock, because the Company’s common stock price exceeded $17.22 for at least 20 trading days in a period of 30 consecutive trading days, the Company’s Board of Directors approved the conversion and the preferred shareholders were notified by mail on November 21, 2013. The conversion was effective December 23, 2013. Each share of the Series E Preferred Stock was converted into the number of shares of common stock that resulted from dividing $1,000 (the issuance price per share of the Series E Preferred Stock) by $12.15 (the conversion price per share). No fractional shares were issued as a result of the conversion of the Series E Preferred Stock. Instead, holders received cash totaling $1,915 which equaled the amount of fractional shares multiplied by $17.24 (the closing price of the Company’s common stock on December 20, 2013). As a result of the conversion, the Company issued 2,057,502 shares of common stock. Senior Non-Cumulative Perpetual Preferred Stock, Series F: On September 15, 2011, the Company issued 40,090 shares of Series F Preferred Stock to the Treasury for an aggregate purchase price of $40,090,000. The sale of Series F Preferred Stock was the result of an investment by the Treasury from the Small Business Lending Fund, a $30 billion fund established under the Small Business Jobs Act of 2010 that encourages lending to small businesses by providing capital to qualified community banks with assets of less than $10 billion. On June 29, 2012, the Company redeemed 10,223 shares of Series F Preferred Stock from the Treasury for an aggregate redemption amount of $10,223,000 plus unpaid dividends to the date of redemption of $124,948. On March 31, 2014, the Company redeemed 15,000 shares of Series F Preferred Stock for an aggregate amount of $15,000,000 plus unpaid dividends to the date of redemption of $337,500.
