Disclosure of Compensation Related Costs, Share-based Payments [Text Block] | 6.

This amount changes based upon the fair market value of the Company’s stock. As of September 30, 2014, there was $324,990 of total unrecognized compensation expense, net of estimated forfeitures, related to all unvested stock options and restricted stock, which is expected to be recognized over a weighted-average period of 2.99 years.
