A review for indicators of impairment is carried out at each reporting date, with the recoverable amount
being estimated where such indicators exist. Where the carrying value exceeds the recoverable
amount, the asset is impaired accordingly. Prior impairments are also reviewed for possible reversal at
each reporting date.
When it is not possible to estimate the recoverable amount of an individual asset, an estimate is made
of the recoverable amount of the cash-generating unit to which the asset belongs. The cash-generating
unit is the smallest identifiable group of assets that includes the asset and generates cash inflows that
are largely independent of the cash inflows from other assets or groups of assets.
For impairment testing of goodwill, the goodwill acquired in a business combination is, from the
acquisition date, allocated to each of the cash-generating units that are expected to benefit from the
synergies of the combination, irrespective of whether other assets or liabilities of the company are
assigned to those units.
