Stock options vest over a prescribed service period and are approved by the Company's board of directors on an award-by-award basis. Options have a prescribed service period generally lasting up to four years, with certain options vesting immediately upon issuance. Upon the exercise of any stock options, the Company issues shares to the award holder from the pool of authorized but unissued common shares.

Detail of the number of stock options outstanding for the three months ended March 31, 2025 under the Company's 2015 legacy option plan and the Company's amended 2018 long term incentive plan (collectively, the "Plans") is as follows:

The Company has issued time-based restricted share units to certain employees as permitted under the amended 2018 long term incentive plan ("the 2018 Plan"). The restricted share units granted vest in accordance with the board-approved agreement, typically over equal installments up to four years. Upon vesting, one common share of the Company is issued for each restricted share unit awarded. The fair value of each restricted share unit granted is equal to the market price of the Company's shares at the date of the grant. There were no shares vested during the three months ended March 31, 2025. The fair value of shares vested during the three months ended March 31, 2024 was $869.
