2. NET LOSS PER SHARE

3 Months Ended

Mar. 31, 2023

Basic net loss per share is calculated using the weighted-average number of common shares outstanding during the period. Net loss per share, assuming dilution, is calculated using the weighted-average number of common shares outstanding and the dilutive effect of all potentially dilutive securities, including common stock equivalents and convertible securities. Net loss per share, assuming dilution, is equal to basic net loss per share because the effect of dilutive securities outstanding during the period, including options and warrants computed using the treasury stock method, is anti-dilutive.

The components of basic and diluted net loss per share were as follows (in thousands, except loss per share data):
