Earnings Per Share [Abstract]  
Income (Loss) Per Common Share
Basic income (loss) per share is computed by dividing net income (loss) by the weighted average number of common shares outstanding for the period. Diluted income (loss) per share is based on the weighted average number of shares outstanding during each period and the assumed exercise of potentially dilutive stock options and warrants and vesting of RSUs less the number of treasury shares assumed to be purchased from the proceeds using the average market price of the Company’s stock for each of the periods presented.
Basic and diluted loss per common share is computed as follows (in thousands, except share and per share amounts):
