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 share 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 three months ended March 31, 2013, 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.

For the three months ended March 31, 2012, diluted earnings per share included 181,000 shares of common stock associated with outstanding options and warrants, 235,000 issuable upon conversion of our convertible preferred stock calculated using the treasury stock method, and 1,265,000 shares of unvested restricted stock.
