An impairment review should be carried out at the end of the
first full financial year following acquisition (
CIRD30110) and if events or changes in
circumstances indicate that the carrying amount of the fixed asset
or goodwill may not be recoverable. Impairment occurs because
something has happened either to the fixed assets, or to the
economic environment in which they are used.
Examples of the sort of changes that might signify the need
for an impairment review include:
The impairment review should compare the carrying amount of the
intangible asset with its recoverable amount. The carrying amount
is the value in the balance sheet, while the recoverable amount is
the
higher of net realisable value and value in use.
If the net realisable value cannot be ascertained then the value in
use is taken.
FRS11 gives details of the calculation methods, but if your
concerns extend to this level of detail, then you should be seeking
advice from a Revenue accountant. In general value in use would
probably be based on anticipated cash flows including ultimate
disposal value.
The value in use of a fixed asset should be estimated
individually where reasonably practicable. Where it is not
reasonably practicable to identify cash flows arising from an
individual fixed asset, value in use should be calculated at the
level of income-generating units. The carrying amount of each
income-generating unit containing the fixed asset or goodwill under
review should be compared with the higher of the value in use and
the net realisable value (if it can be measured reliably) of the
unit.
The value in use of a fixed asset is the present value of the
future cash flows obtainable as a result of the asset's continued
use, including those resulting from its ultimate disposal. In
practice, it is not normally possible to estimate the value in use
of an individual fixed asset, it is the utilisation of groups of
assets and liabilities, together with their associated goodwill,
that generates cash flows. Hence value in use will usually have to
be estimated in total for groups of assets and liabilities. These
groups are referred to as income-generating units.
CIRD30560 describes how impairment
losses are recognised in the accounts and the circumstances in
which they may be reversed.
