Earnings Per Share [Abstract]

Net Loss Per Share

Net Loss Per Share

The company accounts for and discloses net loss per common share in accordance with FASB ASC Topic 260 “Earnings per Share.” Basic net loss per common share is computed by dividing net loss attributable to common stockholders by the weighted average number of common shares outstanding. Diluted net loss per common share is computed by dividing net loss attributable to common stockholders by the weighted average number of common shares that would have been outstanding during the period assuming the issuance of common shares for all potential dilutive common shares outstanding. Potential common shares consist of shares issuable upon the exercise of stock options and warrants.

The following table sets forth the potential common shares excluded from the calculation of net loss per common share because their inclusion would be anti-dilutive (in thousands):
