Earnings Per Share [Text Block]

Earnings Per Share

Basic earnings per common share excludes dilution and is computed by dividing Net income attributable to common stockholders by the weighted average number of common shares outstanding for the period. Diluted earnings per share reflects the potential dilution that could occur if securities or other obligations to issue common stock were exercised or converted into common stock or resulted in the issuance of common stock that shared in our earnings.

A reconciliation of the numerators and denominators of basic and diluted earnings per share is presented below:
