Stock-Based Compensation [Abstract] 
Stock-Based Compensation
17. Stock-Based Compensation
The Company maintains stock incentive plans whereby stock option grants or awards of restricted stock may be made to certain officers, directors and key employees. The plans, which are shareholder approved, permit the award of up to 1,350,000 shares of the Company’s common stock, of which 272,026 shares were still available for grant at September 30, 2011. When options are exercised, new shares of the Company’s common stock are issued. Stock options may not be granted below 100% of the fair market value of the Company’s common stock at the date of grant and generally expire seven years from the date of grant. Stock options and awards of restricted stock vest over a period determined by the plan administrator, typically a one to five year period. The stock incentive plans provide for accelerated vesting of stock options and removal of restrictions on restricted stock awards upon a change in control (as defined in the plans).
Stock-based compensation cost charged against income for the three and six months ended September 30, 2011, was approximately $271,000 and $456,000, respectively. The Company recorded stock-based compensation expense of $189,000 and $327,000 for the three and six months ended September 30, 2010, respectively.
As of September 30, 2011, total unrecognized compensation cost related to stock options was approximately $2.4 million and the related weighted-average period over which it is expected to be recognized is approximately 2.5 years.
