Note 9 – Net Loss per Share of Common Stock

Basic net loss per share is computed by dividing net loss by the weighted average common shares outstanding and vested RSUs. Diluted net loss per share is computed by dividing net loss by the diluted weighted average common shares outstanding, which includes potentially dilutive effect of stock options, unvested RSAs, unvested RSUs, warrants and previously outstanding senior convertible notes. Since we experienced a loss for all periods presented, basic and diluted net loss per share are the same and, as they would have an anti-dilutive impact on diluted net loss per share, any dilutive common shares outstanding were excluded from the computation shown below. The treasury-stock method is used to determine the dilutive effect of our stock options and warrants, and the if-converted method is used to determine the dilutive effect of the Senior Notes.

The computation of net loss per share for the three and nine months ended September 30, 2021 and 2020 was as follows:
