Capital Shares | Reverse Share Split On June 7, 2019, the Company effected a reverse split of the Company's common shares at a ratio of 1-for-6. As a result of the reverse split, every six shares of the issued and outstanding common shares, without par value, consolidated into one newly issued outstanding common share, without par value, after fractional rounding. All shares and exercise prices are presented on a post-split basis in these consolidated financial statements. Black-Scholes option valuation model The Company uses the Black-Scholes option valuation model to determine the fair value of share-based compensation for share options and compensation warrants granted. 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 and share options. Warrants A summary of the Company’s warrants activity is as follows: Weighted Number of Average Warrants (#) Exercise Price Balance – December 31, 2018 and 2017 — $ — Effect of reverse acquisition 362,430 31.60 Black-Scholes value payout (313,516 ) 33.01 Balance – September 30, 2019 48,914 $ 11.19 The fair value of warrants acquired in the reverse acquisition that subsequently had a Black-Scholes value payout totaled $1,187,124. The weighted average contractual life remaining on the outstanding warrants at September 30, 2019 is 49 months. The following table summarizes information about the warrants outstanding at September 30, 2019: Number of Warrants (#) Exercise Prices Expiry Dates 28,124 $ 15.90 May 2023 20,790 4.81 June 2024 48,914 Share Options The Company adopted an Equity Incentive Compensation Plan in 2019 (the 2019 Plan) administered by the Board of Directors, which amended and restated the 2017 Incentive Compensation Plan (the 2017 Plan).

The number of shares available for issuance under the 2019 Plan is 1,153,147, including shares available for the exercise of outstanding options under the 2017 Plan. The Company's 2019 Plan allows options to be granted to directors, officers, employees and certain external consultants and advisers. Under the 2019 Plan, the option term is not to exceed 10 years. The term, vesting and exercise price of each option is determined by the independent members of the Board of Directors upon grant.

The Company recorded approximately $35,000 and $81,000 of share-based compensation expenses for the nine-month transition period ended September 30, 2019 and year ended December 31, 2018 respectively. As of September 30, 2019, the Company had approximately $30,000 of unrecognized share-based compensation expense, which is expected to be recognized over a period of 27 months. Issued and outstanding common shares: Number of Common Shares (#) Common Shares Balance – December 31, 2018 and 2017 3,239,902 $ 1,111,253 Conversion of preferred shares upon reverse acquisition 3,376,112 6,260,299 Share consideration transferred upon reverse acquisition 888,454 4,633,499 Balance – September 30, 2019 7,504,468 $ 12,005,051 Issued and outstanding preferred shares: Class A Preferred Class A Preferred Shares (#) Shares Balance – December 31, 2017 1,007,143 $ 5,616,801 Preferred return on Class A preferred shares — 447,212 Balance – December 31, 2018 1,007,143 $ 6,064,013 Preferred return on Class A preferred shares — 196,286 Conversion upon reverse acquisition (1,007,143 ) (6,260,299 ) Balance – September 30, 2019 — $ — The Class A preferred shares are voting and convertible into common shares at the option of the holder at any time. Upon the occurrence of a liquidation event, as defined in the resolutions of the shareholders dated August 28, 2017, the Class A preferred shares have a liquidation amount preference over the rights of holders of common shares or any class of shares ranking junior to Class A preferred shares. The Class A preferred shares also contain an 8% preferred return that accrues daily and compounds annually and is payable in shares upon conversion. The Company has evaluated the convertible preferred shares and the embedded conversion option. The embedded conversion option does not meet the criteria for bifurcation and has therefore been classified to equity. Following the completion of the reverse acquisition on June 7, 2019, all the outstanding Class A preferred shares and accumulated accrued preferred return were fully converted to 3,376,112 common shares based on the fair market value upon conversion. |
