Stock options that commence vesting upon the achievement of market, performance and service conditions (‘Hybrid Options”). These options will vest ratably over a period of 36 months beginning when all of the following have occurred: (i) the option recipient has been employed by the Company for at least one year, (ii) the Company’s shares of Common Stock have been listed for trading on a national stock exchange, and (iii) such date no later than July 31, 2023, when the Company’s closing stock price exceeds $0.58 per share for 20 trading days in any consecutive 30 day period.

The Company has not recognized any expense related to these stock options for the three and six months ended December 31, 2019, since it is not yet probable that the performance condition will be achieved. The Company will begin recognizing compensation expense at such time that the performance condition is probable and continuing through the end of the requisite service period. Determination of the requisite service period and valuation of the Hybrid Options will be calculated on the date that the performance condition is considered probable.

Unrecognized stock-based compensation expense related to stock options that provide solely for time-based vesting as of December 31, 2019 is approximately $4.8 million. This amount is expected to be recognized over a remaining weighted average period of 2.2 years. Unrecognized compensation cost has not yet been determined for an aggregate of 11,250,000 shares for the Hybrid Options since the valuation is required to be performed on the date that the performance condition becomes probable. However, based on preliminary estimates using the BSM option-pricing model, management believes the aggregate fair value will be approximately $2.0 million before adjusting for forfeitures.
For the six months ended December 31, 2019, the aggregate fair value of stock options granted for approximately 24.7 million shares of Common Stock that provide solely for time-based vesting, amounted to $4.3 million or approximately $0.18 per share as of the grant date. Fair value was computed using the BSM option-pricing model and will result in the recognition of compensation cost ratably over the expected vesting period of the stock options. For the six months ended December 31, 2019, the fair value of each time-based option was estimated on the date of grant using the BSM option-pricing model, with the following weighted-average assumptions:

Represents warrants granted for consulting services in November 2019 with an expiration date in November 2024. The fair value the warrants of $67,000 was determined using the BSM model. Since the warrants were immediately vested, this entire amount is included in consulting and outside services under research and development expenses for the three and six months ended December 31, 2019. Key assumptions for the valuation of these warrants included the closing price of the Company’s shares of common stock of $0.13 on the grant date, the exercise price of $0.29 per share, historical volatility of 119%, and an expected term of 5 years.
