For the three and six months ended June 30, 2012 and 2013, 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,
	2012	2013	2012	2013
Basic weighted-average common shares outstanding	15,535	15,706	15,495	15,647
Stock options	74	115	86	109
Diluted weighted-average common shares outstanding	15,609	15,821	15,581	15,756

The above calculations for the three months ended June 30, 2012 and 2013 do not include 381,000 and 60,000 shares, respectively, related to certain stock options because the effects of such were anti-dilutive. For the six months ended June 30, 2012 and 2013, the calculation does not include 353,000 and 153,000 shares, respectively, related to certain stock options because the effect of such options was anti-dilutive.
