Stock-Based Compensation In November 2016, our Board of Directors amended the 2003 Incentive Stock Option Plan (the “2003 Plan”) and the 2013 Omnibus Stock and Incentive Plan (the “2013 Plan”) to permit equitable adjustments to outstanding awards in the event of a special dividend. In March 2017, the Board of Directors approved the modification of all outstanding stock option awards to provide option holders with substantially equivalent economic value after the effect of the dividend. The modification resulted in the issuance of options to purchase up to 150,476 additional shares. Total stock-based compensation expense for the modifications was approximately $79,000, of which $78,000 was recorded during the six months ended June 30, 2017. During the six months ended June 30, 2017, no other stock option awards were granted by the Company beyond the modification discussed above. During the six months ended June 30, 2016, the Company issued options to purchase an aggregate of 20,000 shares of common stock under its 2013 Omnibus Stock and Incentive Plan, as amended, with a weighted average exercise price of $2.90. The Company estimated the fair value of these awards using the following weighted average assumptions: expected life of 2.5 years, expected volatility of 41%, dividend yield of 0% and risk-free interest rate of 1.00%. During the six months ended June 30, 2017, the Company issued 8,424 restricted stock units under the 2013 Plan. The shares underlying the awards were assigned a value of $1.51 per share, which was the closing price of our common stock on the date of grant, and are scheduled to vest over a weighted average of 1.5 years following the date of grant. During the six months ended June 30, 2016, the Company issued 100,000 shares of restricted stock under the 2013 Plan. The shares underlying the awards were assigned a value of $2.33 per share, based on the stock price on the date of the grant, and are scheduled to vest over five years. The Company estimated the fair value of stock-based awards granted during the six months ended June 30, 2017, under the Company’s employee stock purchase plan using the following weighted average assumptions: expected life of 1.0 years, expected volatility of 51%, dividend yield of 0% and risk-free interest rate of 0.89%. During June 2017, non-employee members of the Board of Directors received grants totaling 72,115 fully vested shares of common stock pursuant to the 2013 Plan. The shares were assigned a value of $1.04 per share, based on the closing price on the grant date, for a total value of $75,000, which is included in stock-based compensation expense for the six months ended June 30, 2017. During May and June 2016, members of the Board of Directors received grants totaling 54,036 fully vested shares of common stock pursuant to the 2013 Plan. The shares were assigned a weighted average value of $2.19 per share, based on the stock prices on the applicable grant dates, for a total value of $119,000, of which $109,000 is included in stock-based compensation expense for the six months ended June 30, 2016 and $10,000 was accrued for and expensed in 2015. Total stock-based compensation expense recorded for the three and six months ended June 30, 2017 was $127,000 and $274,000, respectively, and for the three and six months ended June 30, 2016 was $82,000 and $108,000, respectively. During the three and six months ended June 30, 2017, there were no options exercised. During each of the three and six months ended June 30, 2016, there were approximately 61,000 shares issued pursuant to stock option exercises, for which the Company received proceeds of $16,000. A portion of the stock option exercises in the three and six months ended June 30, 2016 were completed on a cashless basis. Net Loss per Share . Due to the net loss incurred during the three and six months ended June 30, 2017 and 2016, all stock awards were anti-dilutive for both periods.
