Disclosure of Compensation Related Costs, Share-based Payments [Abstract] |
Disclosure of Compensation Related Costs, Share-based Payments [Text Block] | 3. STOCK-BASED COMPENSATION We have one stock option plan which provides for annual stock option grants to non-employee directors with an exercise price equal to the fair market value of the shares at the date of grant. Under this plan, 12,000 options were awarded to directors in each of the first nine months of 2013 and 2012. These options vest and become exercisable six months from the option grant date. We had two other stock option plans from 1995 which provided for stock option grants to officers, key employees and non-employee directors. These plans expired in 2005. The expiration of the plans has no effect on the options previously granted. Options outstanding and exercisable were granted at a stock option price which was not less than the fair market value of our common stock as of closing on the date the option was granted and no option has a term in excess of ten years. No share based compensation expense was recognized in each of the quarters ended September 30, 2013 and 2012. Share based compensation expense of $11,686 and $10,000 was recognized for the nine month periods ended September 30, 2013 and 2012, respectively, as a component of operating expenses. During the nine months ended September 3 0, 2013 and 2012, the stock option activity under our stock option plans was as follows:
