The Company has a restricted share unit plan (“RSU” plan) whereby restricted share units ("RSUs") may be granted to senior management of the Company. Such RSUs may be redeemed by the holder in shares or cash, with cash redemptions subject to the approval of the Board. The current maximum number of common shares authorized for issue under the RSU plan is 5,000,000. As at December 31, 2021, 268,283 common shares purchased by the Company remain held in trust in connection with this plan and have been included in treasury stock within equity on the consolidated statement of financial position.

These RSUs are exercisable into one common share once vested, for no additional consideration. They vest as follows: one third on the first anniversary of the grant date, one third on the second anniversary of the grant date and one third on the third anniversary of the grant date. RSUs with no performance criteria terminate on the third anniversary of the grant date. All vested RSUs which have not been redeemed by the date of termination are automatically redeemed. Such RSUs may be redeemed by the holder in shares or cash, with cash redemptions subject to the approval of the Board.

A total of 180,132 RSUs with no performance criteria at an average grant-date fair value of CDN $13.79 per unit were granted during the year ended December 31, 2021 under the Company’s RSU plan. The fair value of each RSU issued is determined based on the quoted market value of the Company's shares on date of grant.

RSUs with performance criteria vest on the third anniversary of the grant date, subject to achievement of pre-determined market-based performance criteria. When fully vested, the number of RSUs redeemed will range from 0% to 200% of the target award, subject to the performance of the share price over the three-year period.

There were 360,273 RSUs with performance criteria granted during the year ended December 31, 2021 with a fair value of CDN $22.46 per unit. In addition, 80,235 RSUs with performance criteria were granted as a result of the performance criteria being met during the year, which were then redeemed for common shares issued from treasury stock. The fair value of each RSU with market-based performance criteria issued is determined based on fair value of the share units on the date of grant which is based on a valuation model which uses the expected future forward price of the Company's shares and an index consisting of global gold-based securities.

The Company has an independent directors deferred unit plan (“DU Plan”) under which deferred units ("DU’s") are granted by the Board from time to time to independent directors (“the Participants”). DUs may be redeemed only on retirement of the independent director from the Board (the “Termination Date”) by providing the redemption notice (“Redemption Notice”) to the Company specifying the redemption date which shall be no later than December 15 of the first calendar year commencing after the calendar year in which the Termination Date occurred (the “Redemption Date”). The participant receives a cash payment equal to the market value of such DUs as of the Redemption Date.

At December 31, 2021, 351,232 DUs were outstanding (2020 – 289,360) with a fair value of $3,291 (2020 – $3,834), which is included in accounts payable and accrued liabilities. The fair value was determined based on the closing share price at December 31, 2021.

The Company has a Performance Share Unit plan (the “PSU” Plan) whereby PSUs may be granted to senior management of the Company at the discretion of the Board of Directors. Under the plan, PSUs cliff vest on the third anniversary of the grant date (the “Redemption Date”) and are subject to terms and conditions including the achievement of predetermined performance criteria (the “Performance Criteria”). When fully vested the number of PSUs redeemed will range from 0% to 200% of the target award, subject to the achievement of the Performance Criteria. Once vested, at the option of the Company, PSU’s are redeemable as a cash payment equal to the market value of the vested PSUs as of the Redemption Date, common shares of the Company equal to the number of vested PSUs, or a combination of cash and shares equal to the market value of the vested PSUs, for no additional consideration from the PSU holder and to be redeemed as soon as practicable after the Redemption Date.

There were 13,937 PSUs were granted during the year ended December 31, 2021 under the PSU Plan (December 31, 2020 – $nil) with a fair value of CDN $24.40 per unit (December 31, 2020 – $nil). In addition, 253,999 PSUs were granted as a result of the performance criteria being met during the year, which were then redeemed for common shares. The current maximum number of common shares authorized for issuance from treasury under the PSU Plan is 3,126,000. The fair value of each PSU issued is determined based on fair value of the share units on the date of grant which is based on the expected future forward price of the Company's shares and an index consisting of global gold securities.
