Net Income Per Share

12 Months Ended

Jan. 31, 2022

Basic net income per share is computed using the weighted average number of shares of common stock outstanding during the period. Diluted net income per share is computed using the weighted average number of shares of common stock outstanding during the period and potentially dilutive common shares, including the effect of restricted stock units, performance share awards, and stock options using the treasury stock method. The following table sets forth the computation of the numerators and denominators used in the basic and diluted net income per share amounts:


	Fiscal Year Ended January 31,
	2022		2021		2020
Numerator:
Net income	$	497.0	$	1,208.2	$	214.5
Denominator:
Weighted average shares for basic net income per share	219.7		219.4		219.7
Effect of dilutive securities	2.3		2.7		2.8
Weighted average shares for dilutive net income per share	222.0		222.1		222.5
Basic net income per share	$	2.26	$	5.51	$	0.98
Diluted net income per share	$	2.24	$	5.44	$	0.96

The computation of diluted net income per share does not include shares that are anti-dilutive under the treasury stock method because their exercise prices are higher than the average market value of Autodesk’s stock during the fiscal year. The effect of 0.2 million and 0.1 million potentially anti-dilutive shares were excluded from the computation of diluted net income per share for the fiscal years ended January 31, 2022 and 2021, respectively. There were no potentially anti-dilutive shares excluded from the computation of diluted net income per share for the fiscal year ended January 31, 2020.
