Equity Incentive Awards

We follow Codification Topic "Stock Compensation" ("FASB ASC 718") in accounting for our share-based payments. This guidance requires measurement of the cost of employee services received in exchange for stock compensation based on the grant-date fair value of the employee stock awards. This cost is recognized as compensation expense ratably over the employee's requisite service period. Incremental compensation costs arising from subsequent modifications of awards after the grant date must be recognized when incurred. We use the Black-Scholes-Merton formula to estimate the value of stock options granted to employees, consultants and directors.

Our 2014 Equity Incentive Plan (the "2014 Plan") was adopted by our Board of Directors on March 11, 2014 and approved by our stockholders on May 13, 2014. Pursuant to the 2014 Plan, our officers, directors, employees and consultants may be awarded (i) shares of common stock ("Restricted Stock Grants"), (ii) options to acquire shares of common stock ("Options"), including non-qualified stock options and incentive stock options within the meaning of Section 422 of the Internal Revenue Code, and (iii) other forms of equity awards subject to conditions and restrictions determined by the Compensation, Nominating, and Corporate Governance Committee of our Board of Directors (the "Compensation Committee"). The Compensation Committee will determine the vesting schedule, if any, of each Restricted Stock Grant or Option and the term of each Option, which term shall not exceed ten years from the date of grant. Shares that do not vest are forfeited. Dividends paid on restricted stock are not returnable, even if the underlying stock does not entirely vest. A maximum of 3,750,000 shares of common stock are available for grant under the 2014 Plan. As of December 31, 2015, 3,405,321 shares remained available for grant.

Grants under the 2014 Plan are made by the Compensation Committee, which determines the individuals eligible to receive awards, the types of awards, and the terms, conditions and restrictions applicable to any award, except grants to directors which are made by the Board of Directors.
