Share-based payments
Share-based payments include option and stock grants granted to directors, employees and non-employees. The Company accounts for share-based compensation using a fair value based method with respect to all share-based payments measured and recognized, to directors, employees and non-employees. For directors and employees, the fair value of the options and stock grants is measured at the date of grant. For non-employees, the fair value of the options and stock are measured at the fair value of the goods or services received or the fair value of the equity instruments issued, if it is determined the fair value of the goods or services cannot be reliably measured, and are recorded at the date the goods or services are received. For directors, employees and non-employees, the fair value of the options and stock grants is accrued and charged to operations, with the offsetting credit to share based payment reserve for options, and commitment to issue shares for stock grants over the vesting period. If and when the stock options are exercised, the applicable amounts are transferred from share-based payment reserve to share capital. When the stock grants are issued, the applicable fair value is transferred from commitment to issue shares to share capital. Option based compensation awards are calculated using the Black-Scholes option pricing model while stock grants are valued at the fair value on the date of grant.
The Company has granted certain employees and non-employess restricted share units (“RSUs”) to be settled in shares of the Corporation. The fair value of the estimated number of RSUs that will eventually vest, determined at the date of grant, is recognized as share-based compensation expense over the vesting period, with a corresponding amount recorded as equity. The fair value of the RSUs is estimated using the market value of the underlying shares as well as assumptions related to the market and non-market conditions at the grant date.
