Note 4. Basic and Diluted Earnings per Share

Diluted earnings attributable to shareholders per share is computed using the weighted average number of common shares and dilutive potential common shares outstanding. Dilutive potential shares represent outstanding stock options, including purchase options under the Company's employee stock purchase plan, and unvested RSUs. Basic earnings attributable to shareholders per share is calculated using the weighted average number of common shares outstanding without taking into consideration dilutive potential common shares outstanding.

The following table reconciles the numerator and the denominator of the basic and diluted per share computations for earnings attributable to shareholders:
