10. NET INCOME (LOSS) PER SHARE

For the three and nine months ended September 30, 2017 and 2016, 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 September 30,		Nine months ended September 30,
	2017	2016	2017	2016
Basic weighted-average shares of common stock outstanding	16,178	16,148	16,177	16,128
Stock options	—	93	—	100
Diluted weighted-average shares of common stock outstanding	16,178	16,241	16,177	16,228

The above calculation does not include approximately 5,000 shares related to certain stock options because the effects of such options were anti-dilutive during both the three and nine months ended September 30, 2016, respectively.
