Decrease in decommissioning provision results in negative asset
Question
We operate a power plant and we recognized a provision related to its decommissioning at the end of its useful life.
We remeasure the amount of the provision annually based on updated discount rate and estimated cost report. We apply cost model to our power plant and we recognize a change in the provision in the cost of a powerplant (Debit PPE-power plant / Credit Provision).
This year, however, the discount rate ended up being high which caused a huge decrease in the provision.
As a result, the carrying amount of the power plant became negative, because the decrease of the provision was greater that the carrying amount of the plant.
Should we show the negative net book value in our PPE related to the power plant?
Answer
The interpretation IFRIC 1 deals with this issue.
You should never decrease the carrying amount of the asset below zero as a result of a huge decrease in provision.
You can reduce that to zero and than excess should be recognized in profit or loss.
Let’s say your provision decreased by CU 10 000, but the carrying amount of the related power plant is CU 8 000. Your journal entry would be:
-
Debit Provision for decommissioning: CU 10 000
-
Credit PPE – Power plant: CU 8 000
-
Credit Profit or loss: CU 2 000

What if the date to dismantle the cost of the property was not the same as the end of the end of the useful life of the asset. For example, the asset is estimated to have a useful life of 10 years. However, based on certain regulation that came in it states that the property must be dismantled by a certain date which is in 15 years. Would you base the discounting on 10 years or 15 years?
You should base the discounting on the 15-year period, as the dismantling provision (IAS 37) is linked to the actual timing of the legal or constructive obligation, regardless of the asset’s useful life. However, keep in mind that the associated decommissioning asset will be fully depreciated over its 10-year useful life, potentially leading to a mismatch between depreciation and the unwinding of the discount in later years.
