Basic and Diluted Net Loss Per Common Share

5.Basic and Diluted Net Loss Per Common Share

Basic and diluted net loss per common share is computed based on the weighted-average number of common shares outstanding. Common share equivalents (which consist of options and warrants) are excluded from the computation of diluted net loss per common share where the effect would be anti-dilutive.  Common share equivalents that could potentially dilute net loss per share in the future, and which were excluded from the computation of diluted loss per share, totaled 44.8 million shares for each of the three-month and six-month periods ended June 30, 2017, and 22.4 million shares for each of the three-month and six-month periods ended June 30, 2016.
