Basic loss per common share attributable to our shareholders is calculated by dividing the net loss attributable to our shareholders by the weighted average number of outstanding common shares during the period.

Diluted loss per share is calculated by taking net loss, divided by the diluted weighted average common shares outstanding. Diluted net loss per share equals basic net loss per share because the effect of securities convertible into common shares is anti-dilutive.

The following table includes the number of shares that may be dilutive potential common shares in the future. The holders of these shares do not have a contractual obligation to share in our losses and thus these shares were not included in the computation of diluted loss per share because the effect was either antidilutive.
