The Company issued 200,000 stock option awards, with a weighted average exercise price of $2.82, during the nine months ended September 30, 2015, and the Company estimated the fair value of these awards using the following weighted average assumptions: expected life of 3.4 years, expected volatility of 45%, dividend yield of 0% and risk-free interest rate of 1.18%. The Company estimated the fair value of stock-based rights granted during the nine months ended September 30, 2015, under the Company’s employee stock purchase plan using the following weighted average assumptions: expected life of 1.0 years, expected volatility of 37%, dividend yield of 0% and risk-free interest rate of 0.25%.

Total stock-based compensation (benefit) expense recorded for the three and nine months ended September 30, 2015 was ($11,000) and $267,000, respectively, and for the three and nine months ended September 30, 2014 was $83,000 and $300,000, respectively.

During the three and nine months ended September 30, 2015, there were approximately 80,000 shares and 113,000 shares issued pursuant to stock option exercises, for which the Company received proceeds of $0 and $2,000, respectively.

Basic net income per share is computed by dividing net income by the weighted average shares outstanding and excludes any potential dilutive effects of outstanding stock options and restricted stock units. Diluted net income per share gives effect to all diluted potential common shares outstanding during the period. Options to purchase approximately 660,000 and 653,000 shares of common stock with a weighted average exercise price of $3.64 and $3.80, respectively, were outstanding at September 30, 2015 and were not included in the computation of common stock equivalents for the three and nine months ended September 30, 2015 because their exercise prices were higher than the average fair market value of the common shares during the reporting period. Options to purchase approximately 695,000 and 578,000 shares of common stock with a weighted average exercise price of $4.20 and $4.27, respectively, were outstanding at September 30, 2014 and were not included in the computation of common stock equivalents for the three and nine months ended September 30, 2014 because their exercise prices were higher than the average fair market value of the common shares during the reporting period.
