The Company has three incentive plans. One was adopted in 2004 (2004 Plan) and provided for the granting of stock options and restricted stock awards to employees, board members and consultants and generally prescribed a contractual term of seven years. The 2004 Plan terminated in August 2010. However, grants made under the 2004 Plan are still governed by that plan. As of June 30, 2014, options to purchase 23,954 shares of common stock at an exercise price of $3.24 per share remained outstanding under the 2004 Plan. |
The Company approved the 2010 Employee, Director and Consultant Equity Incentive Plan (2010 Plan) in September 2010 to replace the 2004 Plan. The 2010 Plan provided for the granting of stock options and restricted stock awards to certain employees, members of the board of directors and consultants of the Company. As of June 30, 2014, the number of shares of common stock authorized for issuance in connection with the 2010 Plan was 681,788. As of June 30, 2014, there were no shares available for issuance under the 2010 Plan. |
The 2010 Plan terminated upon the Initial Public Offering. However, grants made under the 2010 Plan are still governed by that plan. |
The Company approved the 2013 Equity Incentive Plan (2013 Plan) in October 2013. The 2013 Plan became effective immediately on adoption although no awards were to be made under it until the effective date of the Registration Statement for the Initial Public Offering. The 2013 Plan provides for the granting of stock options, restricted stock, stock appreciation rights, stock units, and performance cash awards to certain employees, members of the board of directors and consultants of the Company. As of June 30, 2014, the number of shares of common stock authorized for issuance in connection with the 2013 Plan was 625,000. As of the first business day of each fiscal year of the Company during the term of the Plan, commencing on the first day of the Company’s 2015 fiscal year, the aggregate number of common shares that may be issued under the Plan shall automatically increase by a number equal to the least of (a) 4% of the total number of common shares outstanding on the last calendar day of the prior fiscal year, (b) subject to adjustment for certain corporate transactions, 333,333 common shares, or (c) a number of common shares determined by the Company’s board of directors. As of June 30, 2014, there were 469,852 shares available for issuance under the 2013 Plan. |
Options granted for the year ended December 31, 2013 include two grants of options exercisable for a total of 32,014 common shares for which vesting is contingent on certain performance conditions. For options granted containing performance conditions, the fair value is determined on the date of grant. For the three and six months ended June 30, 2014, there was $340,372 expense recorded relating to the options as the performance conditions were satisfied in May 2014. |
