Basic and Diluted Loss Per Share [Abstract]

BASIC AND DILUTED LOSS PER SHARE

8. BASIC AND DILUTED LOSS PER SHARE

Basic net loss per common share is computed by dividing net loss attributable to common shareholders by the weighted average number of common shares outstanding during the period. Diluted net loss per common share is computed giving effect to all dilutive potential common shares that were outstanding during the period. Diluted potential common shares consist of incremental shares issuable upon exercise of stock options and warrants and conversion of preferred stock. In computing diluted net loss per share for the three months ended October 31, 2011 and 2010, no dilution adjustment has been made to the weighted average outstanding common shares because the assumed exercise of outstanding options and warrants and the conversion of preferred stock would be anti-dilutive.

Potential common shares not included in calculating diluted net loss per share are as follows:

Stock options		1,491,250		2,505,832
Series C Preferred Stock		1,551,200		1,551,200
Series D Preferred Stock		13,975,000		13,975,000
Total		17,017,450		18,032,032
