Under this agreement, the Company issued to the Treasury Department 57,000 shares of Fixed Rate Cumulative Perpetual Preferred Stock, Series A (“preferred stock”), having a liquidation amount per share of $1,000, for a total price of $57 million and a warrant (Warrant”) to purchase up to 571,906 shares of the Company’s common stock, at an initial per share exercise price of $14.95, for an aggregate purchase price of $8,550.  On June 6, 2013, the Treasury Dept. announced it had completed an auction to sell the Warrant in a private transaction.   The preferred stock pays cumulative dividends at a rate of 5% per year for the first five years and 9% per year thereafter. Dividends are payable quarterly in arrears on February 15, May 15, August 15 and November 15 of each year. The Company may, at its option and at any time, redeem the preferred stock for the liquidation amount of $1,000 per share, plus any accrued and unpaid dividends. While the preferred stock is outstanding, the Company may only pay dividends on common stock if all accrued and unpaid dividends for the preferred stock have been paid.   On March 28, 2012, the U.S. Department of the Treasury priced its secondary public offering of 57,000 shares of the Company’s Preferred Stock. The Company successfully bid for the purchase of 21,030 shares of the Preferred Stock for a total purchase price of $19,581, plus accrued and unpaid dividends on the Preferred Stock from and including February 15, 2012 to the settlement date, April 3, 2012. The book value of the preferred stock retired was $20,823. As a result of its successful bid in the offering, the Company retired 21,030 shares of its original sale of 57,000 shares of Preferred Stock on March 29, 2012. The difference between the book value and the bid price of $1,242 was credited to retained earnings.  On May 31, 2012 the Company purchased an additional 1,820 shares or $1,820 in liquidation value of the preferred stock at a cost of $1,747.  The difference between the book value and bid price of $60 was credited to retained earnings.  On December 5, 2012, the Company purchased an additional 19,050 shares or $19,050 in liquidation value of the preferred stock at a cost of $18,927.  The difference between the book value and bid price of $55 was credited to retained earnings. The $1,242 and $60 are included in the second quarter and six months ending June 30, 2012 calculations shown in Note 7.   See Note 14 - Subsequent Event for additional information on the Company’s preferred stock.   </div>falsefalsefalsenonnum:textBlockItemTypenaThe disclosure pertaining to the entity's agreement, as part of the U.
