Issuance of Common Stock in Lieu of Cash Payments
Under the terms of the Amended and Restated Non-Employee Director Compensation Plan, each non-employee member of the Companys Board of Directors may elect to receive all or part of his or her director fees in shares of the Companys common stock. Director fees, whether paid in cash or in shares of common stock, are payable quarterly on the last day of each fiscal quarter. The number of shares of common stock issued to directors is determined by dividing the product of: (i) the fees otherwise payable to each director in cash, times (ii) the percentage of fees the director elected to receive in shares of common stock, by (iii) the volume weighted average price per share of common stock over the last five trading days of the quarter. During the three months ended June 30, 2016 and 2015, 2,824 shares and 939 shares, respectively, were issued to directors as payment for director fees in lieu of cash. During the six months ended June 30, 2016 and 2015, 6,374 shares and 5,744 shares, respectively, were issued to directors as payment for director fees in lieu of cash.
Stock Incentive Plans
The Company has various share-based compensation plans and share-based compensatory contracts (collectively, the Plans) under which it has granted share-based awards, such as stock grants, and incentive and non-qualified stock options, to employees, directors, consultants and advisors. Awards may be subject to a vesting schedule as set forth in individual award agreements. Certain of the Plans also have provided for cash-based performance bonus awards.
In June 2013, the Companys stockholders approved the 2013 Incentive Compensation Plan. Upon its approval, the Company ceased making awards under other previous Plans, although then-outstanding awards made under such other previous Plans remain outstanding in conformity with their original terms. At the 2015 Annual Meeting, the Companys stockholders approved the adoption of the MRI Interventions, Inc. Amended and Restated 2013 Incentive Compensation Plan (the Amended 2013 Plan). The material change effected in the Amended 2013 Plan was to increase the number of shares of the Companys common stock available for awards thereunder by 125,000 shares, resulting in a total of 156,250 shares of the Companys common stock being reserved for issuance under the Amended 2013 Plan. Of this amount, stock grants of 22,359 shares have been awarded and option grants of 81,616 shares were outstanding as of June 30, 2016. Accordingly, 52,275 shares remained available for grants under the Amended 2013 Plan as of that date.
Activity under all of the Companys Plans during the six months ended June 30, 2016 is summarized below:
