A. If the related asset is measured using the cost model, a change in the existing decommissioning, restoration or similar
liability related to cash flows or discount rate shall be added to or deducted from the cost of the related asset in the current
period.
B. The amount deducted from the cost of the asset shall not exceed its carrying amount. If a decrease in the liability exceeds the
carrying amount of the asset, the excess shall be recognized immediately in profit or loss.
C. The adjusted depreciable amount of the asset is depreciated over its useful life. Therefore, once the related asset has reached the
end of its useful life, all subsequent changes in the liability shall be recognized in profit or loss as they occur. This applies under
the cost model, but not the revaluation model.
