Earnings Per Share [Abstract]

Earnings Per Share

Earnings (Loss) Per Share

Earnings (loss) per share is calculated by dividing net earnings attributable to common stockholders by the weighted average number of share of common shares outstanding during the period. Diluted earnings (loss) per share reflects the potential dilution from the conversion or exercise into common stock of securities such as stock options and warrants.

For the nine and three months ended September 30, 2013 and September 30, 2012, diluted loss per share is the same as basic loss per share due to the net loss and the potential shares of common stock that could have been issuable have been excluded from the calculation of diluted loss per share because the effects, as a result of our net loss, would be anti-dilutive. Such potentially dilutive shares of common stock consist of the following (in thousands):
