For the three and six months ended June 30, 2011 and 2012, 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,
	2011	2012	2011	2012
Basic weighted-average common shares outstanding	15,394	15,535	15,389	15,495
Stock options	103	74	102	86
Diluted weighted-average common shares outstanding	15,497	15,609	15,491	15,581

The above calculations for the three months ended June 30, 2011 and 2012 do not include 293,000 and 381,000 shares, respectively, related to certain stock options because the effects of such were anti-dilutive. For the six months ended June 30, 2011 and 2012, the calculation does not include 245,000 and 353,000 shares, respectively, related to certain stock options because the effect on such options was anti-dilutive.
