The Company reported a net loss for the three and nine months ended September 30, 2021 and 2020, therefore, the basic and diluted net loss per share are the same in the respective period because the inclusion of potential common shares would have an anti-dilutive effect. Potential shares of common stock that are excluded from the computation of diluted weighted-average shares outstanding are as follows:

In addition, common shares issuable upon the conversion of the Notes were excluded for all periods in which the Notes were outstanding.
