Disclosure Of Compensation Related Costs Sharebased Payments [Abstract]

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 $53 and $111 for the three and six month periods ended June 30, 2014, respectively, compared to $70 and $139 for the same periods in 2013.

As of June 30, 2014, there was approximately $349 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 2.2 years.

Stock Options and Stock Grants

During the six months ended June 30, 2014, no stock options were exercised. During the six months ended June 30, 2013, 10,000 shares were issued pursuant to stock option exercises with proceeds of $3 realized. During the six months ended June 30, 2014, 568,000 stock options were granted compared to 553,000 for the same period in 2013. During the six months ended June 30, 2014, 22,000 stock options were forfeited compared to 91,133 stock options forfeited during the same period in 2013.

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 six months ended June 30, 2014 and 2013. 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 June 30, 2014 and 2013, and adjusted to fair value each reporting period. The fair value of the liability on June 30, 2014 was $4 compared to $8 on December 31, 2013.

As of June 30, 2014, we did not have any unvested restricted stock or performance shares outstanding.
