If the change means an increase in the carrying cost of the asset, it might be
appropriate to consider whether there has been any impairment to the asset.
(If the asset has been measured using the revaluation model, the basic rule is that
any increase in the liability/provision should be recognised in profit or loss; and
any reduction in the liability should be reported as other comprehensive income
and added to the revaluation reserve for the asset.)
Example
Entity STV established an operating plant on 1 January Year 1. The initial cost of the
plant was $12 million and it has a 40-year expected life. This initial cost included a
provision for future decommissioning costs at the end of 40 years. These costs were
estimated at $7.4 million, and had a present value of $1 million when discounted at
the applicable rate of 5%.
After 10 years, the estimated costs of decommissioning have been revised and the
present value of these future liabilities is now only $0.8 million.
By the end of 10 years, the provision for future decommissioning costs has risen,
with the unwinding of the discount, to $1.63 million (= $1 million × 1.05)
10
). The
change on the estimated liability therefore means that the liability is reduced by
$0.83 million.
The carrying amount of the asset after 10 years, assuming straight line depreciation
and a nil residual value, is $9 million (= $12 million × 30/40). The reduction in the
provision/liability of $0.83 million should be deducted from this carrying amount,
so that the revised carrying amount is $8.17 million.
The asset should now be depreciated at the rate of $8.17 million/30 years =
$272,000 per year.
In the next year, the finance cost for unwinding the discount on the
provision/liability will be $0.8 million × 0.05 = $40,000.
4.2 IFRIC Interpretation 5: rights to interests in an environmental
rehabilitation fund
IFRIC 5 (Rights to interests arising from decommissioning, restoration and
environmental rehabilitation funds) deals with a situation in which a fund is
established by an entity or a number of different entities to provide for future
decommissioning or environmental rehabilitation costs. Money is paid into the fund
and invested. The entity or entities are subsequently able to draw on money from
the fund to meet their future obligations when these arise.
IFRIC 5 states that in such a situation, an entity that is a contributor to such a fund
should report the liability for the future obligation separately from its interest in the
benefits from the fund.
The future obligation is reported as a provision and valued at present value
(with the discount unwinding each year).
