3. Net Income Per Share

Basic net income per share is computed by dividing net income by the weighted average number of common shares outstanding, while diluted net income per share is computed by dividing net income attributable to common stockholders by the sum of the weighted average number of common shares outstanding and the weighted average number of dilutive potential common shares. Dilutive potential common shares relate to our share-based compensation arrangements.

The calculation of basic and diluted net income per share is as follows.
