Earnings Per Share [Abstract]

Earnings per share

2. Earnings per share

Basic net income per share is calculated by dividing net income attributable to the Company, adjusted for any change in noncontrolling interests 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 and unvested stock units (under the treasury stock method) as well as contingently returnable shares held in escrow.

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