3.	Basic and Diluted Loss per Common Share

Basic loss per share is computed by dividing net loss by weighted average number of outstanding shares of common stocks outstanding for the period. Diluted net loss per share adjusts the weighted average shares outstanding for the potential dilution that could occur if outstanding vested stock options were exercised and restricted stock units ("RSU") were vested, unless the impact of potential dilutive common shares outstanding has an anti-dilutive impact on diluted net loss per share. Since we experienced a net loss for both periods presented, basic and diluted net loss per share are the same. As such, diluted loss per share for the three months ended March 31, 2019 and 2018 excludes the impact of potentially dilutive common shares related to the exercise of outstanding stock options and the vesting of RSUs since those shares would have an anti-dilutive effect on loss per share.

The weighted average number of common shares and common share equivalents used in the determination of basic and diluted loss per share were as follows:
