NET LOSS PER SHARE

6.    NET LOSS PER SHARE

Net loss per share is computed using the weighted average number of common shares outstanding. Basic and diluted net loss per share amounts are equivalent for the periods presented as the inclusion of potential common shares in the number of shares used for the diluted computation would be anti-dilutive to loss per share. Unvested restricted stock, although legally issued and outstanding, are not considered outstanding for purposes of calculating basic net income per share. The weighted average number of common shares outstanding excludes 206,653 and 334,214 unvested shares of restricted stock for the three and six months ended June 30, 2011 and 2010, respectively and 390,000 performance-based stock units for the three and six months ended June 30, 2011.  There were no performance-based stock units outstanding at June 30, 2010. Potential common shares, the shares that would be issued upon the exercise of outstanding stock options, were 6,965,518 and 6,238,332 for the three and six months ended June 30, 2011 and 2010, respectively.
