Earnings Per Share [Abstract] |
Net Loss Per Share | 11. Net Loss Per Share Basic and diluted net loss per share attributed to common stockholders is calculated by dividing net loss attributed to common stockholders by the weighted-average number of common shares outstanding during the period, without consideration for common stock equivalents. The Company’s potentially dilutive shares, which include preferred stock, unvested RSAs and options to purchase common stock, are considered to be common stock equivalents and are only included in the calculation of diluted net loss per share when their effect is dilutive. Potentially dilutive common shares have been excluded from the diluted net loss per common share computations in all periods presented because such securities have an anti-dilutive effect on net loss per common share due to the Company’s net losses. There are no reconciling items used to calculate the weighted-average number of total common shares outstanding for basic and diluted net loss per common share. As of September 30, 2021 and 2020 potentially dilutive securities were as follows:
|  | September 30, |
|  | 2021 |  |  | 2020 |
Convertible preferred stock |  |  | - |  |  |  | 194,474,431 |
Unvested RSAs |  |  | 3,575,002 |  |  |  | 9,486,462 |
Options to purchase common stock |  |  | 43,561,067 |  |  |  | 32,358,470 |
Total |  |  | 47,136,069 |  |  |  | 236,319,363 |
