The potential shares of common stock that were excluded from the computation of diluted net income (loss) per share attributable to common stockholders for the periods presented because including them would have been anti-dilutive are as follows:


	Year Ended January 31,
	2020			2019			2018
	Class A	Class B	Class A	Class B	Class A	Class B
Convertible preferred stock	—	—	—	—	—	152,665,804

The table above does not include 500,000 shares of issued Class A common stock held by us and reserved for the sole purpose of being transferred to a nonprofit organization to be formed or identified by us at a future time.

The convertible promissory notes are contingently convertible (convertible upon completion of an IPO or a qualified financing event as discussed in Note 6), and the conditions for the convertible feature were not satisfied as of January 31, 2019. For fiscal year ended January 31, 2019, we have excluded these potential dilutive shares from the calculation of diluted net income per share attributable to common stockholders.
