NET INCOME PER SHARE |
NET INCOME PER SHARE | 10. NET INCOME PER SHARE For the three and six months ended June 30, 2013 and 2014, 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 June 30, |  | Six Months Ended June 30, |
|  | 2013 |  | 2014 |  | 2013 |  | 2014 |
Basic weighted-average common shares outstanding |  | 15,706 |  | 15,915 |  | 15,647 |  | 15,873 |
Stock options |  | 115 |  | 108 |  | 109 |  | 113 |
Diluted weighted-average common shares outstanding |  | 15,821 |  | 16,023 |  | 15,756 |  | 15,986 |
The above calculation for the three months ended June 30, 2013 does not include 60,000 shares related to certain stock options because the effects of such options were anti-dilutive. For the six months ended June 30, 2014 the calculation does not include 153,000 shares related to certain stock options because the effect of such options was anti-dilutive.
