Net Loss Per Share

 

(4) NET LOSS PER SHARE

Basic and diluted net loss per share is computed by dividing net loss by the weighted average number of common shares outstanding for the applicable period. Diluted net loss per share excludes the effect of outstanding potentially dilutive securities because they are anti-dilutive. The following table shows the outstanding potentially dilutive options, unvested restricted stock awards, warrants and convertible notes for the three months ended March 31, 2012 and 2011 (in thousands):
