Option valuation models require the input of highly subjective assumptions including the expected price volatility. The Company has used historical volatility to estimate the volatility of the share price. Changes in the subjective input assumptions can materially affect the fair value estimates, and therefore the existing models do not necessarily provide a reliable single measure of the fair value of the Company’s warrants, broker units and share options. Warrants Number of Warrants Weighted Balance - September 30, 2015 1,022,761 CDN $ 12.12 Granted 40,000 CDN $ 4.00 Exercised (424,000) CDN $ 4.00 Expired (40,000) CDN $ 4.00 Balance - June 30, 2016 598,761 $ 13.33 As a result of the exercise and expiration of warrants in the quarter ended December 31, 2015, there are no outstanding warrants with exercise prices denominated in Canadian dollars at June 30, 2016. The weighted average contractual life remaining on the outstanding warrants at June 30, 2016 is 2.4 Exercise Price Number of Expiry Date $13.50 470,190 September 9, 2016 $10.50 20,000 September 9, 2016 Broker warrants $13.50 95,238 September 20, 2016 $10.50 13,333 September 20, 2016 Broker warrants 598,761 Warrant liability All warrants with exercise prices denominated in Canadian dollars were exercised or expired. Therefore there is no outstanding warrant liability at June 30, 2016. Equity offerings conducted by the Company in prior years included the issuance of warrants with exercise prices denominated in Canadian dollars. The Company’s functional currency is the U.S. dollar. As a result of having exercise prices denominated in other than the Company’s functional currency, these warrants met the definition of derivatives and were therefore classified as derivative liabilities measured at fair value with adjustments to fair value recognized through the consolidated statements of operations. As these warrants were exercised, the fair value of the recorded warrant liability on date of exercise was included in common shares along with the proceeds from the exercise. When these warrants expired, the related decrease in warrant liability was recognized in profit or loss, as part of the change in fair value of warrant liability. There was no cash flow impact as a result of this accounting treatment. The fair value of the warrants was determined using the Black-Scholes option valuation model at the end of each reporting period. Upon exercise of the warrants, the fair value of warrants included in derivative liabilities was reclassified to equity.
