Earnings Per Share [Text Block] | Note 14 – Net Loss Per Share Basic net loss per common share is computed by dividing net loss by the weighted average number of common shares and pre-funded warrants outstanding for the period. Diluted net loss per share is computed by dividing net loss by the weighted average number of common shares outstanding during the period after giving effect to all dilutive potential common shares that were outstanding during the period. Dilutive potential common shares consist of the incremental common shares issuable upon the exercise of outstanding warrants, stock options and stock appreciation rights. Due to our net loss for the periods presented, all potentially dilutive instruments were excluded because their inclusion would have been anti-dilutive. See Notes 9 and 10 for a discussion of our potentially dilutive common shares.
