Stockholders' Equity Note [Abstract] |
Preferred and Common Stock | Preferred and Common Stock Preferred Stock On January 9, 2009, the Company issued $25,000,000 in Fixed Rate Cumulative Perpetual Preferred Stock, Series A, to the U.S. Treasury under the Capital Purchase Program ("the CPP Shares"). The CPP Shares qualified as Tier 1 capital on the Company's books for regulatory purposes and ranked senior to the Company's common stock and senior or at an equal level in the Company's capital structure to any other shares of preferred stock the Company may issue in the future. In three separate transactions in 2012 and 2013, the Company repurchased all of the CPP Shares from the Treasury. Incident to such issuance of the CPP Shares, the Company issued to the U.S. Treasury warrants (the "Warrants") to purchase up to 225,904 shares of the Company's common stock at a price per share of $16.60 (subject to adjustment). The Warrants (and any shares of common stock issuable pursuant to the Warrants) are freely transferable by Treasury to third parties. The warrants have a term of 10 years and could be exercised by Treasury or a subsequent holder at any time or from time to time during their term. To the extent they had not previously been exercised, the Warrants will expire after ten years. The Warrants were unchanged as a result of the CPP Shares repurchase transactions. In May 2015, the Treasury sold all of the Warrants to private parties. In accordance with the contractual terms of the Warrants, the number of shares issuable upon exercise of the Warrants and the strike price were adjusted at the time of the sale. As a result of this transaction, the number of shares issuable under the Warrants was adjusted to 226,819 with a strike price of $16.53 per share. In November 2016, the Company repurchased all of the outstanding Warrants for an aggregate purchase price of $1,750,000. Common Stock In 2016, the Company reserved 250,000 shares of its common stock to be made available to directors and employees who elect to participate in the stock purchase or savings and investment plans. As of December 31, 2016, 14,511 shares had been issued pursuant to these plans, leaving 235,489 shares available for future use. The issuance price is based on the market price of the stock at issuance date. Prior to 2016, the Company had reserved 700,000 shares of its common stock to be made available to directors and employees who elect to participate in the stock purchase or savings investment plans. As of December 31, 2015, 562,224 shares had been issued pursuant to these plans. The issuance price was based on the market price of the stock at issuance date. Sales of stock to directors and employees amounted to 13,787 shares in 2015 and 14,638 shares in 2014. In 2001, the Company established a dividend reinvestment plan to allow shareholders to use their cash dividends for the automatic purchase of shares in the Company. When the plan was established, 600,000 shares were registered with the Securities and Exchange Commission, and as of December 31, 2016, 247,837 shares have been issued, leaving 352,163 shares usable for future issuance. Participation in this plan is optional and at the individual discretion of each shareholder. Shares are purchased for the plan from the Company at a price per share equal to the average of the daily bid and asked prices reported on the NASDAQ System for the five trading days immediately preceding, but not including, the dividend payment date. Sales of stock under the dividend reinvestment plan amounted to 10,889 shares in 2016, 11,668 shares in 2015, and 12,686 shares in 2014. Issuance of common stock for plans totaled $531,000, $465,000 and $457,000 for the years ended December 31, 2016, 2015 and 2014, respectively.
