h) Share-based payments
Equity settled share based payments to employees and other third parties providing services are measured at the fair value of the equity instruments at grant date. The fair value determined at grant date of the equity-settled share-based payments is expensed on a pro rata basis over the vesting period, based on the estimated number of equity instruments that will eventually vest. At the end of each reporting period, Hudson revises its estimate of the number of equity instruments expected to vest.
The impact of the revision of the original estimates, if any, is recognized in the statement of comprehensive income such that the cumulative expense reflects the revised estimate.
Where the terms of an equity settled award are modified, the minimum expense recognized is the expense as if the terms had not been modified. An additional expense is recognized for any modification, which increases the total fair value of the share-based payment arrangement, or is otherwise beneficial to the holder of the option as measured at the date of modification.
