NET INCOME (LOSS) PER SHARE |
NET INCOME (LOSS) PER SHARE | 10.NET INCOME (LOSS) PER SHARE For the three months ended March 31, 2014 and 2015, outstanding stock options were the only potentially dilutive securities. The reconciliation from basic to diluted weighted average common shares outstanding is as follows (in thousands):
|  | Three Months Ended March 31, |
|  | 2014 |  | 2015 |
Basic weighted-average common shares outstanding |  | 15,830 |  | 15,939 |
Stock options |  | 120 |  | — |
Diluted weighted-average common shares outstanding |  | 15,950 |  | 15,939 |
The above calculation for the three months ended March 31, 2015 does not include approximately 173,000 shares related to certain stock options because the effects of such were anti-dilutive. There were no anti-dilutive securities for the three months ended March 31, 2014.
