Stockholders' Equity

Stock Incentive Plans

In November 2017, our stockholders approved an amendment to our Amended and Restated 2010 Stock Incentive Plan to increase the number of shares of common stock reserved for issuance under the plan by 2,000,000 shares.

Our stock incentive plans permit the granting of stock options (both incentive and nonqualified stock options), restricted stock units (“RSUs”), stock appreciation rights, non-vested stock, and performance shares to certain employees, directors and consultants. As of March 31, 2018, no stock appreciation rights, non-vested stock, or performance shares were outstanding.
