Net Income per Share |
Net Income per Share Basic net income per share is computed by dividing net income by the weighted-average number of shares of common stock outstanding during the period. Diluted net income per share is computed by dividing net income by the weighted-average shares outstanding, including potentially dilutive shares of common equivalents outstanding during the period. The dilutive effect of potential shares of common stock are determined using the treasury stock method. The computation of fully diluted net income per share of Class A common stock assumes the conversion from Class B common stock, while the fully diluted net income per share of Class B common stock does not assume the conversion of those shares. The numerators and denominators of the basic and diluted net income per share computations for our common stock are calculated as follows (in thousands, except per share data): | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fiscal year ended January 31, | | | | | 2021 | | 2020 | | 2019 | | | | | | | | | Class A | | Class B | | Class A | | Class B | | Class A | | Class B | Basic | | | | | | | | | | | | | | | | | | | | Numerator | | | | | | | | | | | | | | | | | | | | Net income, basic | | | | | | | | | $ | 341,866 | | | $ | 38,132 | | | $ | 266,104 | | | $ | 35,014 | | | $ | 194,607 | | | $ | 35,225 | | Denominator | | | | | | | | | | | | | | | | | | | | Weighted average shares used in computing net income per share, basic | | | | | | | | | 135,547 | | | 15,119 | | | 130,610 | | | 17,186 | | | 122,137 | | | 22,107 | | Net income per share, basic | | | | | | | | | $ | 2.52 | | | $ | 2.52 | | | $ | 2.04 | | | $ | 2.04 | | | $ | 1.59 | | | $ | 1.59 | | Diluted | | | | | | | | | | | | | | | | | | | | Numerator | | | | | | | | | | | | | | | | | | | | Net income, basic | | | | | | | | | $ | 341,866 | | | $ | 38,132 | | | $ | 266,104 | | | $ | 35,014 | | | $ | 194,607 | | | $ | 35,225 | | Reallocation as a result of conversion of Class B to Class A common stock: | | | | | | | | | | | | | | | | | | | | Net income, basic | | | | | | | | | 38,132 | | | — | | | 35,014 | | | — | | | 35,225 | | | — | | Reallocation of net income to Class B common stock | | | | | | | | | — | | | 21,409 | | | — | | | 17,652 | | | — | | | 14,800 | | Net income, diluted | | | | | | | | | $ | 379,998 | | | $ | 59,541 | | | $ | 301,118 | | | $ | 52,666 | | | $ | 229,832 | | | $ | 50,025 | | Denominator | | | | | | | | | | | | | | | | | | | | Number of shares used for basic net income per share computation | | | | | | | | | 135,547 | | | 15,119 | | | 130,610 | | | 17,186 | | | 122,137 | | | 22,107 | | Conversion of Class B to Class A common stock | | | | | | | | | 15,119 | | | — | | | 17,186 | | | — | | | 22,107 | | | — | | Effect of potentially dilutive common shares | | | | | | | | | 10,066 | | | 10,066 | | | 10,500 | | | 10,500 | | | 11,873 | | | 11,873 | | Weighted average shares used in computing net income per share, diluted | | | | | | | | | 160,732 | | | 25,185 | | | 158,296 | | | 27,686 | | | 156,117 | | | 33,980 | | Net income per share, diluted | | | | | | | | | $ | 2.36 | | | $ | 2.36 | | | $ | 1.90 | | | $ | 1.90 | | | $ | 1.47 | | | $ | 1.47 | | | | | | | | | | | | | | | | | | | | | |
