Earnings per share

Basic net income per share is calculated by dividing net income attributable to the Company, adjusted for any change in noncontrolling interest redemption rights in excess of fair value, by the weighted average number of common shares and vested stock units outstanding, net of shares held in escrow that under certain circumstances may be returned to the Company.

Diluted net income per share includes the dilutive effect of outstanding stock-settled stock appreciation rights (SSARs), stock options and unvested stock units (under the treasury stock method) as well as shares held in escrow that the Company expects will remain outstanding.

The reconciliations of the numerators and denominators used to calculate basic and diluted net income per share are as follows:
