Impairment losses recognised for goodwill are not reversed in
future periods.
For any other non-financial assets an assessment
is made at each end of the reporting period as to whether there
is any indication that previously recognised impairment losses
may no longer exist or may have decreased. If such indication
exists, the Group estimates the asset’s or cash-generating unit’s
recoverable amount. A previously recognised impairment loss
is reversed only if there has been a change in the assumptions
used to determine the asset’s recoverable amount since the
last impairment loss was recognised. The reversal is limited
so that the carrying amount of the asset does not exceed its
recoverable amount, nor exceed the carrying amount that would
have been determined, net of depreciation, had no impairment
loss been recognised for the asset in prior years. Such a reversal
is recognised in the Consolidated Income Statement.
