EARNINGS PER SHARE

EARNINGS PER SHARE

Diluted net loss per share is the same as basic net loss per share for the three months ended March 31, 2019 and 2020 because the effects of potentially dilutive items were anti-dilutive, given our net loss during these periods. The following securities as of March 31, 2019 and March 31, 2020 have been excluded from the calculation of diluted weighted-average common shares outstanding because the effect is anti-dilutive (in thousands):
