If the carrying amount of an asset exceeds its recoverable
amount an impairment loss is recognise immediately in profit
or loss. At each end of the reporting period, it is assessed
whether there is any indication that an item of property, plant
and equipment may be impaired (see also below “Impairment
of non-financial assets”).
When a major inspection is performed, its cost is recognised in the
carrying amount of the plant and/or equipment as a replacement
if the recognition criteria are satisfi ed. The carrying amount of the
replaced part is derecognised. All other repairs and maintenance
are recognised as an expense in the Consolidated Income
Statement of the period in which they are incurred. Cost of an
item of property, plant and equipment initially recognised comprise
the initial estimate of costs of dismantling and removing the item
and restoring the site on which it is located at the end of the useful
life of the item on a present value basis. A provision presenting the
asset retirement obligation is recognised in the same amount at
the same date in accordance with IAS 37 “Provisions, Contingent
Liabilities and Contingent Assets”.
