Earnings Per Share [Abstract]  
Earnings Per Share
Earnings Per Share
Basic earnings per common share (EPS) 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 EPS 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 shares that then shared in our earnings.
A reconciliation of the numerators and denominators of the basic and diluted EPS computations is presented below:

Earnings per share from discontinued operations were less than $0.005 for all periods; therefore, net income from continuing operations attributable to common shareholders per share is the same as net income per share in the table above.
