4. STOCKHOLDERS' EQUITY

 

On March 18, 2015, the Company announced the closing of an underwritten sale of 1,225,000 shares of its common stock, as well as 183,750 additional shares of its common stock pursuant to the full exercise of the over-allotment option granted to the underwriters, at a public offering price of $8.00 per share, for gross proceeds of approximately $11.3 million. Net proceeds from this offering were approximately $10.2 million, net of underwriting discounts and offering expenses of approximately $1.1 million. The shares were sold under a shelf registration statement on Form S-3 (File No. 333-200638) that was declared effective by the SEC on December 23, 2014.

 

Equity Incentive Plan

 

The fair value of employee options granted 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 highly subjective assumptions including the expected stock price volatility. The Company's employee stock options have characteristics significantly different from those of traded options, and changes in the subjective input assumptions can materially affect the fair value estimate. Because there has been minimal data for the Company's stock and very little historical experience with the Company's stock options, similar public companies and a pro rata percentage of the Company’s  common stock were used for calculating ADMA’s volatility for comparison and expectations as to the assumptions required for fair value computation using the Black-Scholes methodology.

Guidance for stock-based compensation requires forfeitures to be estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. The Company currently estimates there will be no material forfeitures of options.

 

The weighted average remaining contractual life of stock options outstanding and expected to vest at March 31, 2015 is 7.6 years.  The weighted average remaining contractual life of stock options exercisable at March 31, 2015 is 6.6 years.
