Fixed asset investments are initially recorded at cost, and subsequently stated at cost less any
accumulated impairment losses. Listed investments are measured at fair value with changes in fair
value being recognised in profit or loss.
Impairment
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.
