Basic net loss per share is computed by dividing the net loss attributable to common stockholders by the weighted average number of common shares outstanding during the period. Unvested restricted stock and restricted stock units are excluded from the denominator of basic net loss per share. Diluted net loss per share is computed by dividing the net loss attributable to common stockholders by the weighted average number of common shares plus common equivalent shares for the period, including any dilutive effect from such shares. Since the Company was in a net loss position for all periods presented, net loss per share attributable to common stockholders was the same on a basic and diluted basis, as the inclusion of all potential common equivalent shares outstanding would have been anti-dilutive. Anti-dilutive common equivalent shares were as follows:
|  | As of July 31,
|  | 2021 |  | 2020
Options to purchase common stock |  | 7,393,066 |  |  | 10,952,041 |
Restricted stock and restricted stock units |  | 11,241,985 |  |  | 9,998,039 |
Shares estimated to be purchased under ESPP |  | 207,120 |  |  | 336,113 |
Total anti-dilutive common equivalent shares |  | 18,842,171 |  |  | 21,286,193 |
