Prior to its conversion to common stock in connection with our IPO in September 2020, we considered redeemable convertible preferred stock to be participating securities as preferred stockholders had rights to participate in dividends with the common stockholders. Net losses were not allocated to participating securities as they were not required to fund the losses.

As we have net losses for the years ended December 31, 2022, 2021 and 2020, diluted loss per share is the same as basic loss per share, because potentially dilutive shares are excluded from the computation of loss per share as their effect is anti-dilutive.

The following weighted average potentially dilutive shares are excluded from the computation of diluted loss per share for the periods presented because including them would have been antidilutive:
