Net Loss Per Share Attributable to Common Shareholders

12. Net Loss Per Share Attributable to Common Shareholders

Basic net loss per share is calculated by dividing net loss attributable to common shareholders by the weighted-average number of common shares outstanding during the period. Diluted net loss per share is calculated by adjusting weighted-average shares outstanding for the dilutive effect of common stock equivalents outstanding for the period using the treasury stock method. For purposes of the diluted net loss per share calculation, stock options, unvested restricted common shares and ESPP shares are considered to be common stock equivalents but are excluded from the calculation of diluted net loss per share, as their effect would be anti-dilutive; therefore, basic and diluted net loss per share were the same for all periods presented as a result of the Company's net loss. The Company’s net loss is net loss attributable to common shareholders for all periods presented.

The Company did not include the securities in the following table in the computation of the net loss per share calculations for the years ended December 31, 2024, 2023 and 2022 because the effect would have been anti-dilutive during each period:
