What is Asset Retirement Obligation (ARO)?
An asset retirement obligation is the legal or constructive obligation to dismantle, remove and restore an asset at the end of its useful life, typically arising on long-lived assets such as oil wells, mines, factories or leased premises. Under IAS 16 and IAS 37, the present value of the obligation is added to the asset’s cost and recognized as a provision.
How It Works
- Estimate future decommissioning costs at the end of the asset’s life.
- Discount them to present value using a current pre-tax rate.
- Capitalize the present value to the asset’s cost and recognize a matching provision.
- Unwind the discount each period through finance costs and adjust for changes in estimates.
Saudi Context
Saudi oil services companies and tenants in fitted-out leased offices both recognize AROs for restoration obligations.
Example
A factory has a SAR 10 million estimated decommissioning cost in 20 years. Discounted at 6 percent, the present value of SAR 3.1 million is added to the asset and recognized as an ARO provision.
