The potentially dilutive common shares that were excluded from the calculation of diluted net loss per share because their effect would have been antidilutive for the periods presented are as follows:
| | | | | | | | | | | | | | | | | | | | | | | Year ended September 30, | (in thousands) | | 2022 | | 2021 | | 2020 | Shares subject to options to purchase common stock | | 2,765 | | 3,131 | | 3,948 | | | | | | | | Unvested restricted stock units and performance stock units | | 2,095 | | 707 | | 569 | Unvested shares of common stock issued upon early exercise of stock options | | — | | 3 | | 17 | Shares subject to employee stock purchase plan | | 97 | | 27 | | 33 | Shares subject to warrants to purchase common stock | | — | | — | | 26 | Total | | 4,957 | | 3,868 | | 4,593 |
