Earnings (Loss) Per Share [Abstract] |
Earnings (Loss) Per Share | NOTE 10. EARNINGS (LOSS) PER SHARE Basic earnings (loss) per share is computed by dividing earnings (loss) by the weighted average number of common shares outstanding during each period. Diluted earnings (loss) per share is computed by dividing earnings (loss) by the total of the weighted average number of shares of common stock outstanding during each period, plus the effect of outstanding stock options and unvested restricted stock grants. Potentially dilutive securities are excluded from the computation of diluted earnings (loss) per share if their effect is anti-dilutive. The following table is a reconciliation of basic and diluted shares outstanding used in the calculation of earnings (loss) per share:
|  |  |  | Year Ended December 31, |  |  |  |
| 2011 |  |  | 2010 |  | 2009 |  |
Weighted average shares outstanding - basic |  | 21,845 |  | 19,815 |  |  | 16,867 |
Effect of dilutive stock options |  | 201 |  | 58 |  |  | - |
Effect of dilutive unvested restricted stock |  | - |  | 149 |  |  | - |
Weighted average shares outstanding - diluted |  | 22,046 |  | 20,022 |  |  | 16,867 |
Earnings (loss) per share: |  |  |  |  |  |  |  |
Basic | $ | 0.22 | $ | 2.58 | $ |  | (0.29 | )
Diluted |  | 0.22 |  | 2.56 |  |  | (0.29 | )
For the year ended December 31, 2011, diluted earnings per share excludes the anti-dilutive effect of options to purchase 800 shares of common stock whose exercise prices were higher than the average market price of the Company's common stock for the year ended December 31, 2011 and 750 shares of unvested restricted stock as their required performance or market conditions were not met. For the year ended December 31, 2010, diluted earnings per share excludes the anti-dilutive effect of options to purchase 1,322 shares of common stock whose exercise prices were higher than the average market price of the Company's common stock for the year ended December 31, 2010 and 500 shares of unvested restricted stock as their required performance or market conditions were not met. For the year ended December 31, 2009, basic net loss per share was the same as diluted net loss per share because all potentially dilutive securities were anti-dilutive due to the net loss for the period.
