The Company is authorized to issue an unlimited number of Class A subordinate voting shares and an unlimited number of Class B multiple voting shares. The Class A subordinate voting shares have one vote per share and the Class B multiple voting shares have 10 votes per share. The Class B multiple voting shares are convertible into Class A subordinate voting shares on a one-for-one basis at the option of the holder. Class B multiple voting shares will automatically convert into Class A subordinate voting shares in certain other circumstances.

The Company is authorized to issue an unlimited number of preferred shares issuable in series. Each series of preferred shares shall consist of such number of shares and having such rights, privileges, restrictions and conditions as may be determined by the Company’s Board of Directors prior to the issuance thereof. Holders of preferred shares, except as otherwise provided in the terms specific to a series of preferred shares or as required by law, will not be entitled to vote at meetings of holders of shares.

In 2008, the Board of Directors adopted and the Company’s shareholders approved the Legacy Stock Option Plan (“the Legacy Option Plan”). Immediately prior to the completion of the Company’s May 2015 IPO, and in connection with the closing of the offering, each option outstanding under the Legacy Option Plan became exercisable for one Class B multiple voting share. Following the closing of the Company’s IPO, no further awards were made under the Legacy Option Plan. The Legacy Option Plan continues to govern awards granted thereunder.

The Company’s Board of Directors and shareholders approved a stock option plan ("Stock Option Plan"), as well as a Long Term Incentive Plan ("LTIP"), each of which became effective upon the closing of the Company's IPO on May 27, 2015. On May 30, 2018, the Company’s Board of Directors and shareholders amended both the Stock Option Plan and the LTIP.

The Stock Option Plan allows for the grant of options to the Company’s officers, directors, employees and consultants. All options granted under the Stock Option Plan will have an exercise price determined and approved by the Company’s Board of Directors at the time of grant, which shall not be less than the market price of the Class A subordinate voting shares at such time. For purposes of the Stock Option Plan, the market price of the Class A subordinate voting shares shall be the volume weighted average trading price of the Class A subordinate voting shares on the NYSE for the five trading days ending on the last trading day before the day on which the option is granted. Options granted under the Stock Option Plan are exercisable for Class A subordinate voting shares. Both the vesting period and term of the options in the Stock Option Plan are determined by the Board of Directors at the time of grant. The majority of grants outstanding under both the Stock Option Plan and the Legacy Option Plan have been approved with a four year vesting schedule with 25% vesting after one year and the remainder vesting evenly over the remaining 36 months. Options granted under the Stock Option Plan since November 2017 have been approved with a three year vesting schedule with 1/3 vesting after one year and the remainder vesting evenly over the remaining 24 months. On October 17, 2019, the Company approved the issuance of rollover options, from treasury, under the 6 River Systems 2016 Amended and Restated Stock Option and Grant Plan, adopted on closing of the acquisition of 6RS.

The LTIP provides for the grant of share units, or LTIP Units, consisting of RSUs, performance share units (PSUs), and deferred share units (DSUs). Each LTIP Unit represents the right to receive one Class A subordinate voting share in accordance with the terms of the LTIP. Unless otherwise approved by the Board of Directors, RSUs will vest as to 1/3 each on the first, second and third anniversary dates of the date of grant. Prior to November 2017 all RSU grants were approved with a four year vesting schedule with 25% vesting after one year and the remainder vesting evenly over the remaining 36 months. RSUs granted since November 2017 have been approved with a three year vesting schedule with 1/3 vesting after one year and the remainder vesting evenly over the remaining 24 months. A PSU participant’s grant agreement will describe the performance criteria established by the Company’s Board of Directors that must be achieved for PSUs to vest to the PSU participant, provided the participant is continuously employed by or in the Company’s service or the service or employment of any of the Company’s affiliates from the date of grant until such PSU vesting date. DSUs will be granted solely to directors of the Company, at their option, in lieu of their Board retainer fees. DSUs will vest upon a director ceasing to act as a director. As at the consolidated balance sheet date there have been nil PSUs granted.

The maximum number of Class A subordinate voting shares reserved for issuance, in the aggregate, under the Company's Stock Option Plan and the LTIP was initially equal to 3,743,692 Class A subordinate voting shares. The number of Class A subordinate voting shares available for issuance, in the aggregate, under the Stock Option Plan and the LTIP will be automatically increased on January 1st of each year, beginning on January 1, 2016 and ending on January 1, 2026, in an amount equal to 5% of the aggregate number of outstanding Class A subordinate voting shares and Class B multiple voting shares on December 31st of the preceding calendar year. As at January 1, 2021, there were 25,384,187 shares available for issuance under the Company's Stock Option Plan and LTIP.

(1) As at December 31, 2020, 992,376 of the outstanding stock options were granted under the Company's Legacy Option Plan and are exercisable for Class B multiple voting shares, 1,441,791 of the outstanding stock options were granted under the Company's Stock Option Plan and are exercisable for Class A subordinate voting shares, and 55,110 of the outstanding stock options were granted under the 6 River Systems 2016 Amended and Restated Stock Option and Grant Plan and are exercisable for Class A subordinate voting shares.

In connection with the acquisition of 6RS, 122,080 Class A subordinate voting shares were issued with trading restrictions. The restrictions on these shares are lifted over time and are being accounted for as stock-based compensation as the vesting is contingent on continued employment and therefore related to post-combination services. As at December 31, 2020, 91,560 of the Class A subordinate voting shares remained restricted.

The total intrinsic value of stock options exercised and RSUs settled during the years ended December 31, 2020 and 2019 was $2,047,327 and $833,556, respectively. The aggregate intrinsic value of options exercised is calculated as the difference between the exercise price of the underlying stock option awards and the market value on the date of exercise.

As of December 31, 2020 and 2019, there was $381,318 and $306,355, respectively, of remaining unamortized compensation cost related to unvested stock options and RSUs granted to the Company’s employees. This cost will be recognized over an estimated weighted-average remaining period of 2.06 years. Total unamortized compensation cost will be adjusted for future changes in estimated forfeitures.

All share-based awards are measured based on the grant date fair value of the awards and recognized in the consolidated statements of operations and comprehensive income (loss) over the period during which the employee is required to perform services in exchange for the award (generally the vesting period of the award).

The Company estimates the fair value of stock options granted using the Black-Scholes option valuation model, which requires assumptions, including the fair value of the Company's underlying common stock, expected term, expected volatility, risk-free interest rate and dividend yield of the Company's common stock. These estimates involve inherent uncertainties and the application of management’s judgment. If factors change and different assumptions are used, share-based compensation expense could be materially different in the future.

In addition to the assumptions used in the Black-Scholes option valuation model, the Company also estimates a forfeiture rate to calculate the share-based compensation expense for our awards. The Company's forfeiture rate is based on an analysis of its actual forfeitures. The Company will continue to evaluate the appropriateness of the forfeiture rate based on actual forfeiture experience, analysis of

employee turnover, and other factors. Changes in the estimated forfeiture rate can have a significant impact on share-based compensation expense as the cumulative effect of adjusting the rate is recognized in the period the forfeiture estimate is changed. If a revised forfeiture rate is higher/lower than the previously estimated forfeiture rate, an adjustment is made that will result in an increase/decrease to the share-based compensation expense recognized in the consolidated financial statements.
