Earnings per Share

Basic net loss per share is computed by dividing the net loss for the period by the weighted-average number of common shares outstanding during the period. Diluted earnings (loss) 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

three

months ended

March 31, 2018

and

2017

excluded common stock equivalents because the effect of their inclusion would be anti-dilutive, or would decrease the reported loss per share.

The following table sets forth securities outstanding that could potentially dilute the calculation of diluted earnings per share.
