Basic earnings per share is calculated by dividing net income attributable to controlling interests by the weighted-average number of shares of common stock outstanding. Diluted earnings per share is similar to basic earnings per share, but is adjusted for the effect of potentially issuable common stock, except when inclusion is antidilutive.
