Incentive Stock Bonus Plan-- On July 22, 2014 the Company's shareholders approved the 2014 Incentive Stock Bonus Plan, authorizing the issuance of up to 640,000 shares in the Company’s Incentive Stock Bonus Plan. The shares will only be earned upon the achievement of certain milestones leading to the commercialization of the Company’s Multikine technology, or specified increases in the market price of the Company’s stock. If the performance or market criteria are not met as specified in the Incentive Stock Bonus Plan, all or a portion of the awarded shares will be forfeited. The fair value of the shares on the grant date was calculated using the market value on the grant-date for issuances where the attainment of performance criteria is likely and using a Monte Carlo simulation for issuances where the attainment of performance criteria is uncertain. The grant date fair value of shares issued that remain outstanding as of September 30, 2016 is approximately $8.6 million. The total value of the shares, if earned, is being expensed over the requisite service periods for each milestone, provided the requisite service periods are rendered, regardless of whether the market conditions are met. No compensation cost is recognized for awards where the requisite service period is not rendered. During the years ended September 30, 2016 and 2015, the Company recorded expense relating to the issuance of restricted stock pursuant to the plan of approximately $634,000 and $3.4 million, respectively. At September 30, 2016, the Company has unrecognized compensation expense of approximately $3.1 million which is expected to be recognized over a weighted average period of 5.03 years.
