4.       Net loss per common share

Basic net loss per share is calculated by dividing the net loss attributable to common shareholders by the weighted-average number of common shares outstanding during the period, without consideration for common shares equivalents. Diluted net loss per share is computed by dividing the net loss attributable to common shareholders by the weighted-average number of common share equivalents outstanding for the period determined using the treasury-stock method.

The following diluted securities have been excluded from the computation of diluted weighted-average shares outstanding as of June 30, 2014 and June 30, 2013 as the Company recorded a net loss in all periods and therefore they would be anti-dilutive (in thousands):

	June 30, 2014		June 30, 2013
Options to purchase common shares		1,386		301
Common share purchase warrants		1,001		919
