Stockholders’ Equity
 
2011 Equity Incentive Plan
 
The Company’s 2011 Equity Incentive Plan, as amended and restated (the “Plan”), is designed and utilized to enable the Company to provide its employees, officers, directors, consultants and others whose past, present and/or potential contributions to the Company have been, are or will be important to the success of the Company, an opportunity to acquire a proprietary interest in the Company. A total of 8,000,000 shares of common stock are eligible for issuance under the Plan. The Plan provides for the grant of any or all of the following types of awards: stock options, restricted stock, deferred stock, stock appreciation rights and other stock-based awards. The Plan is administered by the Company’s Board of Directors, or, at the Board’s discretion, a committee of the Board.
 
The fair value of options and warrants is estimated on the date of grant using the Black-Scholes option pricing model. The valuation determined by the Black-Scholes option pricing model is affected by the Company’s stock price as well as assumptions regarding a number of highly complex and subjective variables. These variables include, but are not limited to, expected stock price volatility over the term of the awards, and actual and projected employee stock option exercise behaviors. The risk-free rate is based on the U.S. Treasury rate for the expected life at the time of grant, volatility is based on the average long-term implied volatilities of peer companies, the expected life is based on the estimated average of the life of options and warrants using the simplified method, and forfeitures are estimated on the date of grant based on certain historical data. The Company utilizes the simplified method to determine the expected life of the options and warrants due to insufficient exercise activity during recent years as a basis from which to estimate future exercise patterns. The expected dividend assumption is based on the Company’s history and expectation of dividend payouts.
 
Forfeitures are required to be estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates.
 
Stock Options
 
Options granted under the Plan expire at various times, either five, seven or ten years from the date of grant, depending on the particular grant.
 
On March 1, 2016, the Company granted options to purchase an aggregate of 100,000 shares of common stock to a member of management. The exercise price of the options is $7.00 per share, and one-third of the options will vest on each of December 31, 2016, December 31, 2017, and March 31, 2018.
 
On March 31, 2016, the Company granted options to purchase an aggregate of 1,671,500 shares of common stock to certain executives, non-executive management, and employees. The exercise price of the options is $5.80 per share, and one-third of the options will vest on each of March 31, 2017, March 31, 2018, and March 31, 2019.
 
On March 31, 2016, the Company granted options to purchase an aggregate of 500,000 shares of common stock to certain key employees. The exercise price for 100,000 of these options is $5.80 per share, and such options will vest on January 1, 2017. The exercise price of the remaining 400,000 options is $7.50 per share, and the vesting of such options is dependent upon the achievement of certain royalty income targets.
 
On March 31, 2016, the Company granted options to purchase an aggregate of 150,000 shares of common stock to non-management directors. The exercise price of the options is $5.80 per share, and 50% of the options will vest on each of March 31, 2017 and March 31, 2018.
