Diluted earnings per share (“EPS”) includes the dilutive effect of common stock equivalents and is computed using the weighted-average number of common stock and common stock equivalents outstanding during the reporting period. Diluted EPS for the years ended December 31, 2020, 2019, and 2018 excluded common stock equivalents because the effect of their inclusion would be anti-dilutive or would decrease the reported loss per share.
