Share-Based Compensation

(6) Share-Based Compensation

We follow FASB ASC Topic 718, Share-Based Payments, in which compensation expense is recognized only for share-based payments expected to vest. We recognized compensation expense related to stock options of $46 and $141 for the three and nine month periods ended September 30, 2015, respectively, compared to $45 and $155 for the same periods in 2014.

As of September 30, 2015, there was approximately $246 of total unrecognized compensation cost related to nonvested share-based compensation arrangements granted under our stock option plans. That cost is expected to be recognized over a remaining weighted-average period of 1.7 years.

 

Stock Options and Stock Grants

During the nine months ended September 30, 2015, 69,333 shares of common stock were issued pursuant to option exercises for proceeds of $26. During the nine months ended September 30, 2014, no stock options were exercised. During the nine months ended September 30, 2015, 461,100 stock options were granted compared to 568,000 during the same period in 2014. During the nine months ended September 30, 2015, 248,900 stock options were forfeited compared to 22,000 stock options forfeited during the same period in 2014. We had 2,583,199 stock options outstanding at a weighted average exercise price of $0.95 on September 30, 2015, compared to 2,440,000 stock options outstanding at a weighted average exercise price of $1.15 on December 31, 2014.

Stock Appreciation Rights

Prior to 2011, we granted outside directors stock appreciation rights (SARs). The change in fair value of the awards granted during prior years is included in non-cash compensation expense for the three and nine months ended September 30, 2015 and 2014. The SARs granted vested immediately and are payable upon the directors’ removal or resignation from the position of director. These awards are accounted for as liability awards, included in accrued expenses as of September 30, 2015 and 2014, and adjusted to fair value each reporting period. The fair value of the liability was less than $1 on September 30, 2015 and December 31, 2014.

As of September 30, 2015, we did not have any unvested restricted stock or performance shares outstanding.
