6. Capital shares | 6. Capital Shares Equity offerings On March 2, 2021, the Company closed an underwritten offering of 1,562,500 common shares, no par value, at a price to the public of $6.40 per share less underwriting discounts and commissions. Gross proceeds from the offering amounted to $10.0 million. The Company granted to the underwriters a 30-day option to purchase up to an additional 234,375 common shares, which expired with no further shares issued. On the closing date the Company issued underwriter warrants to purchase an aggregate of up to 109,375 common shares at an exercise price of $8.00 per share, expiring on February 26, 2026. The direct costs related to the issuance of the common shares were $1.11 million. These direct costs were recorded as an offset against gross proceeds. The Company also recorded the fair value of underwriter warrants in the amount of $0.41 million as share-based compensation to non-employees under additional paid-in capital and an offset against gross proceeds. Equity distribution agreements On November 22, 2021, the Company entered into an equity distribution agreement with RBC Capital Markets, LLC (RBCCM), as sales agent. On December 28, 2021, the Company reset the size of the at-the-market equity offering program with RBCCM, such that the Company may offer and sell, from time to time, common shares having an aggregate offering price of up to $10.7 million in gross cash proceeds. RBCCM will use commercially reasonable efforts to sell the common shares from time to time, based upon the Company’s instructions. The Company has no obligation to sell any of the shares, and may at any time suspend sales under the distribution agreement or terminate the agreement in accordance with its terms. The total amount of cash that may be generated under this distribution agreement is uncertain and depends on a variety of factors, including market conditions and the trading price of the Company’s common shares. During the three months ended December 31, 2021, 223,396 common shares were sold under the distribution agreement, resulting in $1.29 million in gross proceeds. The commissions and direct costs of the offering program totaled approximately $0.06 million and were recorded as an offset against gross proceeds. 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 and the fair value of warrants issued. Option valuation models require the input of highly subjective assumptions including the expected price volatility. The Company calculates expected volatility based on historical volatility of the Company’s share price. When there is insufficient data available, the Company uses a peer group that is publicly traded to calculate expected volatility. The Company adopted interest-free rates by reference to the U.S. treasury yield rates. The Company calculated the fair value of share options granted based on the expected life of 5 years, considering expected forfeitures during the option term of 10 years. Expected life of warrants is based on warrant terms. The Company did not and is not expected to declare any dividends. 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.
