Earnings Per Share [Abstract]  
Earnings Per Share
Loss Per Share

Basic loss per share has been computed based upon the weighted average number of common shares outstanding. Diluted loss per share has been computed based upon the weighted average number of common shares outstanding plus the effect of all potentially dilutive common stock equivalents, except when the effect would be anti-dilutive.

The following table sets forth the computation of basic and diluted earnings (loss) per share (in millions, except per share data).
