Net Loss Per Share
 10.    Net Loss Per Share
 
Basic loss per share is computed by dividing the weighted-average number of shares of Class A common stock outstanding, during each period presented. Diluted earnings per share is computed similarly to basic earnings per share except that it reflects the potential dilution that could occur if dilutive securities or other obligations to issue shares of Class A common stock were exercised or converted into shares of Class A common stock.  The computation for basic and diluted loss per share are the same as the diluted calculation excludes certain shares as their effect would be anti-dilutive, as described in the following table:
