Disclosure of Compensation Related Costs, Share-based Payments [Abstract] |
Stock-Based Compensation | Stock-Based Compensation We maintain a stock-based compensation program intended to attract, retain and provide incentives for talented employees and directors and align stockholder and employee interests. Currently, we grant options and restricted stock units ("RSUs") from the 2005 Long-Term Incentive Plan ("2005 LTIP") and the 2010 Equity Compensation Plan (“2010 ECP”). Option and restricted stock unit vesting periods are generally up to three years. We recorded stock-based compensation expense for all equity incentive plans of $130,448 and $189,993 for the three months ended March 31, 2014 and 2013, respectively. Total compensation cost not yet recognized at March 31, 2014 was $576,568 to be recognized over a weighted-average recognition period of 1.6 years. During the first quarter of 2014, no equity grants were made. In the first quarter of 2013, we granted employees a total of 100,000 RSUs with a weighted average fair value of $0.72 per share. On March 31, 2013, some of our employees voluntarily canceled certain outstanding stock options for no consideration. As a result, 805,134 shares were canceled and returned to 2005 LTIP and 2010 ECP plans. The cancellation of these options resulted in the recognition of $49,577 in additional stock-based compensation expense, which represented the fair value of the canceled options that had not yet been recognized as of the date of cancellation. The following table summarizes the stock grants outstanding under our 2005 LTIP and 2010 ECP plans as of March 31, 2014:
| Options Outstanding |  | RSUs Outstanding |  | Options and RSUs Exercised |  | Available Shares |  | Total
2010 ECP | 258,248 |  |  | 105,522 |  |  | 1,060,823 |  |  | 2,261,352 |  |  | 3,685,945 |
2005 LTIP | 33,748 |  |  | 398,766 |  |  | 523,976 |  |  | 43,510 |  |  | 1,000,000 |
Total | 291,996 |  |  | 504,288 |  |  | 1,584,799 |  |  | 2,304,862 |  |  | 4,685,945 |
We also have 160,996 options outstanding under a separate plan which is not authorized to issue any additional shares.
