Preferred Stock [Text Block]	Note 11 – Preferred Stock and Warrants On July 14, 2011, the Company entered into and consummated a Securities Purchase Agreement (the “Purchase Agreement”) with the Secretary of the Treasury of the United States (the “Secretary”) under the Small Business Lending Fund program. Pursuant to the Purchase Agreement, the Company issued 56,600 shares of the Company’s Senior Non-Cumulative Perpetual Preferred Stock, Series B (the “Series B Preferred Stock”), having a liquidation amount per share equal to $1,000, for a total purchase price of $56,600,000. The Series B Preferred Stock was entitled to receive non-cumulative dividends beginning October 1, 2011. The dividend rate, as a percentage of the liquidation amount, could fluctuate on a quarterly basis during the first ten quarters during which the Series B Preferred Stock is outstanding, based upon changes in the level of “Qualified Small Business Lending” or “QSBL” (as defined in the Purchase Agreement) by the Bank. The dividend rate for the first ten dividend periods was one percent (1%). For the eleventh calendar quarter through four and one half years after issuance, the dividend rate is fixed at one percent (1%) based upon the increase in QBSL as compared to the baseline. After four and one half years from issuance, the dividend rate will increase to nine percent (9%) if the stock has not been redeemed. The Series B Preferred Stock may be redeemed at any time at the Company’s option, at a redemption price of 100% of the liquidation amount plus accrued but unpaid dividends to the date of redemption for the current period, subject to the approval of its federal banking regulator. On November 18, 2011 under provisions of the CPP the Company issued to the Treasury warrants for 423,977 shares (as adjusted reflect the 10% stock dividend paid on June 14, 2013) of Company common stock at $6.76 per share (as adjusted for the 10% stock dividend paid on June 14, 2013) were sold by the Treasury. At December 31, 2014 those warrants remain outstanding and have an expiration date of December 8, 2018. Upon exercise, which is at the option of the holder, the Company will issue a number of shares of Company common stock in exchange for the warrants equal to the number of shares subject to the warrant less the number of shares determined by multiplying the number of shares subject to the warrant by the strike price and dividing the result by the current share price. Pursuant to the Merger Agreement, each of the 15,300 shares of Virginia Heritage Series A Preferred Stock, was exchanged for one share of the Company’s Series C Preferred Stock, which ranks equally with and has substantially identical terms and conditions as the Company’s existing Series B Preferred Stock.
