Weighted Average Shares Outstanding and Net Income Per Share

Basic net income per share is computed using the weighted-average number of common shares outstanding during the period. Diluted net income per share is computed using the weighted-average number of common shares and dilutive potential common shares outstanding during the period. Dilutive potential common shares include stock options and restricted stock units. The following table presents a reconciliation of the weighted average shares outstanding used in calculating basic and diluted net income per share as well as the calculation of basic and diluted net income per share:
