For the three and nine months ended September 30, 2010 and 2011, 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 September 30,		Nine Months Ended September 30,
	2010	2011	2010	2011
Basic weighted average common shares outstanding	15,349	15,401	15,303	15,393
Stock options	153	88	173	97
Diluted weighted-average common shares outstanding	15,502	15,489	15,476	15,490

The above calculations for the three months ended September 30, 2010 and 2011 do not include 156,000 and 313,000 shares, respectively, related to certain stock options because the effects of such were anti-dilutive. For the nine months ended September 30, 2010 and 2011, the calculation does not include 111,000 and 267,000 shares, respectively, related to certain stock options because the effect on such options was anti-dilutive.
