Stock incentive plan
 
In accordance with accounting standards, the Company measures the cost of employee services received in exchange for an award of equity instruments based on the grant-date fair value of the award (with limited exceptions). That cost is recognized over the period during which an employee is required to provide service in exchange for the award rather than disclosed in the financial statements.
 
The following table summarizes options outstanding under the stock incentive plan at the indicated dates:

During the second quarter of 2016, we granted certain officers 4,000 performance based shares of common stock with a weighted average fair market value of $20.00 at the date of grant. These restricted stock awards vest over two years. During the third quarter of 2016, we granted certain officers 6,250 restricted shares of common stock with a weighted average fair market value of $22.50 at the date of grant. These restricted stock awards have a three-year graded vesting. During the third quarter of 2015, we granted certain officers 40,675 restricted shares of common stock with a weighted average fair market value of $19.72 at the date of grant. Prior to vesting, these shares are subject to forfeiture to us without consideration upon termination of employment under certain circumstances. The total number of shares underlying non-vested restricted stock was 39,080 and 47,893 at December 31, 2016 and 2015, respectively.
 
The fair value of the stock is calculated under the same methodology as stock options and the expense is recognized over the vesting period. Unamortized stock-based compensation related to non-vested share based compensation arrangements granted under the Incentive Plan as of December 31, 2016 and 2015 was $697,000 and $514,000, respectively. The time based unamortized compensation of $374,000 is expected to be recognized over a weighted average period of 1.79 years. During 2016 there were forfeitures of 3,399 shares of restricted stock awards. There were no forfeitures of restricted stock awards in 2015 and 2014.
