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, having a liquidation preference of $1,000 per share, to the U.S. Treasury ("Treasury') under the Capital Purchase Program ("the CPP Shares"). The CPP Shares called for cumulative dividends at a rate of 5.0% per year for the first five years, and at a rate of 9.0% per year in following years, payable quarterly in arrears on February 15, May 15, August 15 and November 15 of each year. On August 24, 2011, the Company repurchased $12,500,000 of the CPP Shares. Almost all of the repayment was made from retained earnings accumulated since the preferred stock was issued in 2009. On March 27, 2013, the Company repurchased $2,500,000 of the CPP Shares with funds from its operating account. On May 8, 2013, the Company repurchased the remaining $10,000,000 CPP Shares using proceeds from the Company's common stock offering in the first quarter of 2013. All the repurchase transactions were approved by the Federal Reserve Bank of Boston, the Company's primary regulator. Incident to such issuance of the CPP shares, the Company issued to the 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 and the Company has filed a registration statement with the Securities and Exchange Commission to allow for possible resale of such securities. The Warrants have a term of ten 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. Treasury will not vote any shares of common stock it receives upon exercise of the Warrants, but that restriction would not apply to third parties to whom Treasury transferred the Warrants. The proceeds from the sale of the CPP Shares were allocated between the CPP Shares and Warrants based on their relative fair values on the issue date. The fair value of the Warrants was determined using the Black-Scholes model which includes the following assumptions: common stock price of $16.60 per share, dividend yield of 4.70%, stock price volatility of 24.43%, and a risk-free interest rate of 2.01%. The discount on the CPP Shares was based on the value that was allocated to the Warrants upon issuance, and has been accreted back to the value of the CPP Shares over a five-year period (the expected life of the shares upon issuance) on a straight-line basis. The Warrants were unchanged as a result of the CPP Shares repurchase transactions and remain outstanding. Common Stock On March 28, 2013, the Company consummated a fully underwritten offering for 760,771 shares of the Company's common stock, with net proceeds of $11,649,000. The Company used these proceeds to repurchase the remaining $10,000,000 of CPP Shares on May 8, 2013. Proceeds from sale of common stock totaled $110,000 and $103,000 for the three months ended March 31, 2015 and 2014, respectively.
