A reconciliation of the weighted average shares outstanding used in calculating basic and diluted net income (loss) per share in the accompanying condensed consolidated statements of operations is as follows:



	Three Months Ended September 30,		Nine Months Ended September 30,
(in thousands)	2011	2010	2011	2010
Weighted average shares outstanding:
Weighted average common stock outstanding	38,669	38,773	38,678	38,747
Less: weighted average unvested restricted stock outstanding	497	908	586	945
Total basic weighted average shares outstanding	38,172	37,865	38,092	37,802

Diluted weighted average shares outstanding:
Weighted average common stock outstanding, basic	38,172	37,865	38,092	37,802
Effect of dilutive securities:
Common stock options and restricted stock units¹	426	206	336	—
Total weighted average shares outstanding assuming dilution	38,598	38,071	38,428	37,802

¹Due to the net loss for the nine months ended September 30, 2010, 146,000 common stock options and restricted stock units have been excluded from the number of shares used in calculating diluted loss per share, as their inclusion would be antidilutive.
