NET INCOME PER SHARE |
NET INCOME PER SHARE | 11. NET INCOME (LOSS) PER SHARE For the three and six months ended June 30, 2016 and 2015, outstanding stock options were the only potentially dilutive securities. The reconciliation from basic to diluted weighted average shares of common stock outstanding is as follows (in thousands):
|  | Three months ended June 30, |  | Six months ended June 30, |
|  | 2016 |  | 2015 |  | 2016 |  | 2015 |
Basic weighted-average shares of common stock outstanding |  | 16,145 |  | 16,038 |  | 16,118 |  | 15,988 |
Stock options |  | — |  | 112 |  | 103 |  | 121 |
Diluted weighted-average shares of common stock outstanding |  | 16,145 |  | 16,150 |  | 16,221 |  | 16,109 |
The above calculation does not include approximately 105,000 shares and 5,000 shares related to certain stock options because the effects of such options were anti-dilutive during the three and six months ended June 30, 2016, respectively. There were no anti-dilutive options for the three months ended June 30, 2015 or the six months ended June 30, 2015.
