Net Income Per Share Net Income Per Share
Basic net income per share is computed by dividing net income attributable to common stockholders by the weighted-average number of common shares outstanding during the period. Diluted net income per share is
computed by dividing net income attributable to common stockholders by the weighted-average number of common shares outstanding during the period adjusted to include the effect of potentially dilutive securities. Potentially dilutive securities are excluded from the computation of dilutive EPS in periods in which the effect would be antidilutive.
The computation of the Company’s basic and diluted net income per share is as follows (in thousands, except per share amounts):
