STOCK-BASED COMPENSATION

During the three months ended September 30, 2018, we granted options for a total of $1,351,515 shares with a weighted average grant date fair value of $0.55 per option. No options were granted during the prior quarters.

 

The fair values of options at the grant date were estimated utilizing the Black-Scholes valuation model with the following weighted average assumptions for the three months ended September 30, 2018: (i) dividend yield on our common stock of 0 percent, (ii) expected stock price volatility of 88 percent, (iii) a risk-free interest rate of 3.2 percent, and (iv) and expected option term of 9 years.

 

General and administrative expense for the three months ended September 30, 2018 included stock-based compensation expense of $8,334. Research and development expenses also included stock-based compensation expenses of $174,504 for the three months ended September 30, 2018. No such expenses were recognized in the prior quarters.

 

As of September 30, 2018, the unrecognized stock-based compensation expenses related to non-vested stock options was approximately $562,000, which will be amortized over an estimated weighted average period of approximately 9 months.
