The Perceptive Warrant became exercisable on the Perceptive Closing Date, and were valued at $2.7 million.

Equity Incentive Plans

The fair value of stock options granted under the Company’s 2007 Employee Stock Option Plan (the “2007 Plan”) and the ADMA Biologics, Inc. 2014 Omnibus Incentive Compensation Plan, as amended and restated (the “2014 Plan”), was determined on the date of grant using the Black-Scholes option valuation model. The Black-Scholes model was developed for use in estimating the fair value of publicly traded options, which have no vesting restrictions and are fully transferable. In addition, option valuation models require the input of certain subjective assumptions including the expected stock price volatility. The stock options granted to employees and directors have characteristics significantly different from those of traded options, and changes in the subjective input assumptions can materially affect the fair value estimate. The following assumptions were used to determine the fair value of options granted during the three months ended March 31, 2019 and 2018: 

 

    Three Months Ended March 31,
    2019   2018
         
Expected term     5.8 - 6.3 years       6.3 years  
Volatility     61 %     57 %
Dividend yield     0.0       0.0  
Risk-free interest rate     2.25-2.63%       2.59 %

  

During the three months ended March 31, 2019 and 2018, the Company granted options to purchase an aggregate of 1,330,850 and 848,700 shares of common stock, respectively, to its directors and employees. Also during the three months ended March 31, 2019 and 2018, the Company granted options to purchase 5,000 and 20,000 shares of common stock, respectively, to third party service providers.

 

The weighted average remaining contractual life of stock options outstanding and expected to vest at March 31, 2019 is 7.8 years. The weighted average remaining contractual life of stock options exercisable at March 31, 2019 is 6.3 years.
