Common Stock Warrants Requiring Liability Accounting
The net-cash settlement and down round provisions contained in common stock warrants issued by the Company in a January 2013 private placement require derivative liability accounting treatment for the warrants. Likewise, the down round provision contained in common stock warrants issued by the Company in a July 2012 private placement also requires derivative liability accounting treatment for the warrants. The fair value of all such warrants was calculated using the Monte Carlo simulation valuation method.
Assumptions used in calculating the fair value of these warrants at June 30, 2014 are noted below:
In addition to the assumptions above, the Company also takes into consideration whether it would participate in another round of equity financing and, if so, what that stock price would be for such a financing at that time.
The fair values and the changes in fair values of the warrants accounted for as a derivative liability are reflected below:
The Company has various share-based compensation plans and share-based compensatory contracts (collectively, the “Plans”). The Plans provide for the granting of share-based awards, such as incentive and non-qualified stock options, to employees, directors, consultants and advisors, and some of the Plans provide for cash-based awards. Awards may be subject to a vesting schedule as set forth in each individual award agreement.
In June 2013, the stockholders of the Company approved the 2013 Incentive Compensation Plan (the “2013 Plan”). Upon stockholder approval of the 2013 Plan, the Company ceased making awards under a previous plan. A total of 1,250,000 shares of the Company’s common stock are reserved for issuance under the 2013 Plan, of which awards as to 1,004,000 shares were outstanding as of June 30, 2014. Thus, awards as to 246,000 shares remained available for grants under the 2013 Plan as of June 30, 2014.
In December 2013, the Company’s board of directors approved the 2013 Non-Employee Director Equity Incentive Plan (the “Director Plan”). A total of 570,000 shares of the Company’s common stock are reserved for issuance under the Director Plan. The shares reserved for issuance under the Director Plan are intended to be used to cover the stock options granted pursuant to the terms of the Company’s Non-Employee Director Compensation Plan. As of June 30, 2014, awards for 250,000 shares had been issued under the Director Plan. Therefore, awards for 320,000 shares remained available for grants under the Director Plan as of June 30, 2014.
Activity under all of the Company’s equity compensation plans during the six months ended June 30, 2014 is summarized below:
The estimated grant date fair values of options granted during the six months ended June 30, 2014 were calculated using the Black-Scholes valuation model, based on the following assumptions:
The Company records share-based compensation expense on a straight-line basis over the related vesting period. For the periods indicated below, share-based compensation expense related to options are:
As of June 30, 2014, there was unrecognized compensation expense of $952,349 related to outstanding stock options, which is expected to be recognized over a weighted average period of approximately 1.6 years.
Warrants have generally been issued for terms of up to five years. Common stock warrant activity for the six months ended June 30, 2014 was as follows:
