5.	Net Loss Per Share

Basic and diluted net loss per share was calculated by dividing the net loss per share attributed to the Company’s common shares by the weighted-average number of common shares outstanding during the period. Diluted net loss per share includes the effect of all dilutive, potentially issuable common equivalent shares as defined using the treasury stock method. All of the Company’s common stock equivalents are anti-dilutive due to the Company’s net loss position for all periods presented. Accordingly, common stock equivalents of approximately 4,139,000 stock options and 9,842,000 warrants at June 30, 2016 and 1,905,000 stock options and 9,842,000 warrants at June 30, 2015, were excluded from the calculation of weighted average shares for diluted net loss per share.
