Earnings Per Share [Abstract]

Earnings (Loss) per Share

Earnings (Loss) per Share

Basic earnings (loss) per share is computed by dividing net income (loss) for the period by the weighted average number of common shares outstanding during the period. Diluted earnings (loss) per share is computed by dividing net income (loss) for the period by the weighted average number of common shares and potentially dilutive common shares outstanding for the period. The calculation of diluted net income per share excludes all antidilutive common shares.
