Equity-settled share based payment transactions are measured at fair value at the date of grant. The fair value is expensed on straight-line basis over the vesting period, with corresponding increase in equity. This is based upon the company's estimate of the shares or share options that will eventually vest, which takes into account all vesting conditions and non-market performance conditions, with adjustments being made where information indicates the number of shares or share options expected to vest from previous estimates.
Fair value is determined using an appropiate pricing model. All market conditions and non-vesting conditions are taken into account when estimating the fair value of the shares or share options. As long as all other vesting conditions are satisfied , no adjustments is made irrespective of whether market or non-vesting conditions are met.
