EARNINGS PER SHARE |
14. | EARNINGS PER SHARE
Basic earnings per share is computed by dividing net income by the weighted average number of common shares outstanding during the year. Diluted earnings per share reflects the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock or resulted in the issuance of common stock that then shared in the earnings of the entity. For CoreCivic, diluted earnings per share is computed by dividing net income by the weighted average number of common shares after considering the additional dilution related to restricted share grants and stock options. A reconciliation of the numerator and denominator of the basic earnings per share computation to the numerator and denominator of the diluted earnings per share computation is as follows (in thousands, except per share data):
