Note 7 Stock-Based Compensation Options - AntriaBio adopted individual stock option plans in January 2013 for four officers and/or directors of the Company. The stock option plans granted 1,500,000 option shares with an exercise price of $4.50 per share. Options to purchase 819,445 shares vested immediately, options to purchase 541,667 shares vest monthly over 3 years and 138,888 shares vest on May 31, 2013.
In June 2013, AntriaBio adopted individual stock option plans for two consultants of the Company. The stock option plans granted 8,334 shares with an exercise price of $4.50 per share. Option to purchase 2,084 shares vested immediately with the remaining shares vesting at various dates through October 2014.
On March 26, 2014, the Company adopted the AntriaBio, Inc. 2014 Stock and Incentive Plan which allows the Company to issue up to 3,750,000 of common stock in the form of stock options, incentive options or common stock. As of September 30, 2014, the Company granted 3,195,000 of these shares to current employees and directors of the Company. The options have an exercise price from $1.75 to $3.44 per share. The options vest monthly over 4 years with some options subject to a one year cliff before options begin to vest monthly.
AntriaBio has computed the fair value of all options granted using the Black-Scholes option pricing model. In order to calculate the fair value of the options, certain assumptions are made regarding components of the model, including the estimated fair value of the underlying common stock, risk-free interest rate, volatility, expected dividend yield and expected option life. Changes to the assumptions could cause significant adjustments to valuation. AntriaBio estimated a volatility factor utilizing a comparable published volatility of a peer company. Due to the small number of option holders and all options being to officers and/or directors, AntriaBio has estimated a forfeiture rate of zero. AntriaBio estimates the expected term based on the average of the vesting term and the contractual term of the options. The risk-free interest rate is based on the U.S. Treasury yield in effect at the time of the grant for treasury securities of similar maturity.
AntriaBio has computed the fair value of all options granted during the three months ended September 30, 2014 using the following assumptions:
Stock option activity is as follows:
Stock-based compensation expense related to the fair value of stock options was included in the statement of operations as payroll expense of $589,007 for the three months ended September 30, 2014. The unrecognized stock-based compensation expense at September 30, 2014 is $7,047,980. AntriaBio determined the fair value as of the date of grant using the Black-Scholes option pricing method and expenses the fair value ratably over the vesting period.

On May 2, 2014, an investor elected to exercise their warrant under a net issue exercise in which 100,550 shares of common stock were issued and 41,570 warrant shares were forfeited.
These warrants were valued using the Black-Scholes option pricing model on the date of issuance except for the warrants to purchase 290,861 shares which were valued using a Lattice pricing model. In order to calculate the fair value of the warrants in both models, certain assumptions were made regarding components of the model, including the closing price of the underlying common stock, risk-free interest rate, volatility, expected dividend yield, and warrant term. Changes to the assumptions could cause significant adjustments to valuation. AntriaBio estimated a volatility factor utilizing a comparable published volatility of a peer company. The risk-free interest rate is based on the U.S. Treasury yield in effect at the time of the grant for treasury securities of similar maturity.
The Black-Scholes valuation methodology was used because that model embodies all of the relevant assumptions that address the features underlying these instruments. Significant assumptions were as follows:
We utilize a Lattice model to determine the fair market value of the warrants to purchase 290,861 shares on the day they were issued. The warrants issued resulted in a warrant derivative liability of $898,719. The Lattice model accommodates the probability of exercise price adjustment features as outlined in the warrant agreement. Under the terms of the warrant agreement, at any time while the warrant is outstanding, the exercise price per share can be reduced in proportion to the exercise price per share of future warrants issued that is lower than the exercise price per share as stated in the warrant agreement. The estimated fair value was derived using the lattice model with the following assumptions:
