The carrying amount of property, plant and equipment is assessed for impairment
losses if events or changes indicate that the carrying amount cannot be recovered.
If an indication of this nature exists, and if the carrying amount of an asset exceeds
its recoverable amount, the asset is written down to its recoverable amount. The
recoverable amount of property, plant and equipment is the higher of its fair value
less costs to sell and its value in use.
If an asset does not generate cash flows that are largely independent of others, the
recoverable amount is determined for the cash-generating unit to which that asset
belongs. Impairment losses are recognised in the Income Statement as part of the
write-downs and impairment losses caption. These impairments losses are reversed
when the reasons leading to that loss no longer exist.
On the sale of an asset or if no future economic benefits are expected from its use, an
asset is derecognized and any gain or loss (calculated as the difference between the
disposal proceeds and the carrying amount) is recognized in the Income Statement
in the year of de-recognition.
