Calculation Of Net Income Per Share Attributable To Verisign Stockholders
Calculation of Net Income per Share
The Company computes basic net income per share by dividing net income by the weighted-average number of common shares outstanding during the period. Diluted net income per share gives effect to dilutive potential common shares, including the conversion spread relating to the Subordinated Convertible Debentures, unvested RSUs, outstanding stock options, and employee stock purchases, using the treasury stock method. The following table presents the weighted-average number of shares used in the calculation of basic and diluted net income per share:
