Disclosure of Compensation Related Costs, Share-based Payments [Abstract] |
Stock Options | STOCK OPTIONS Incentive Options On April 28, 1994, the stockholders approved the 1994 Incentive Stock Option Plan (“1994 ISO Plan”) for key employees. Each option becomes vested and exercisable for up to 20% of the total optioned shares each year after grant. Under the terms of this plan, the exercise price of the shares subject to each option granted would not be less than the fair market value of the common stock at the date the option is granted. There are 39,580 shares outstanding under this option plan. No further option grants can be made under this plan. On May 3, 2005, the stockholders of the Company approved the 2005 Incentive Stock Option Plan (“2005 ISO Plan”) and the Company reserved 500,000 shares of common stock for options to be issued under the 2005 ISO Plan . During the years ended December 31, 2012, 2011 and 2010, options to purchase 61,000 shares, 35,000 shares and 19,000 shares, respectively, were granted under this plan. Each option becomes vested and exercisable for up to 20% of the total optioned shares one year following the grant of the option and for an additional 20% of the total optioned shares after each succeeding year until the option is fully exercisable at the end of the fifth year.
