Stock-Based Compensation

​

The Company’s stock-based compensation plans include: restricted share units (“RSUs”) issuable pursuant to the Company’s long-term equity incentive plan, deferred share units (“DSUs”) issuable pursuant to the Company’s deferred share unit plan (“DSU Plan”), and stock options (“Stock Options”) issuable under the Company’s stock option plan. Stock-based compensation may be issued to our directors, officers, employees, and consultants. The maximum number of Common Shares that may be reserved for issuance under the combined stock-based compensation plans is a variable number equal to 10% of the issued and outstanding Common Shares on a non-diluted basis at any particular time. Stock-based compensation may be granted from time to time at the discretion of the Board of Directors of the Company (the “Board”), with vesting provisions as determined by the Board.

​

​

During the three months ended March 31, 2024 and 2023, the Company withheld Common Shares with an equivalent value to meet employee withholding tax obligations of $85 and $142, respectively, which resulted from the vesting of RSUs during these periods. Common Shares withheld are considered cancelled/forfeited.

​

Deferred Share Units

​

The DSU Plan provides for granting of DSUs to non-employee directors. DSUs vest immediately; however, the Company will issue one Common Share for each DSU only when the non-employee director ceases to be a director of the Company. During the three months ended March 31, 2024, the Board granted 612,000 DSUs and the Company recognized $208 in DSU expense. During the three months ended March 31, 2023, the Board granted 197,000 DSUs and the Company recognized $103 in DSU expense.
