What is an Asset Retirement Obligation?

Asset Retirement Obligation is a legal and accounting requirement, in which a company needs to make provisions for the retirement of a tangible long-lived asset in order to bring the asset back to its original condition after the business is done using the asset.


Companies in several industries have to bring an asset back to its original state after the asset is taken out of service. It may involve industries like oil drilling, power plants, mining, and many other industries. It also applies to the properties taken on lease, where the properties have to be brought back to their original shape. After the use, the asset may have to detoxicate like in nuclear plants or machinery have to be removed like in oil drills.

How Does it Work?

The restorations expenses are incurred at the end of the useful life of the asset. However, a discounted liability is created on the balance sheet along with a corresponding asset right after construction or initiation of the project; or on the determination of the fair value of restoration. This liability is then increased at a fixed rate gradually to match the expected obligation at the end of the life of the asset.

The recognition and accounting of asset retirement obligations are published by the Financial Accounting Standards Board (FASB) in the United States and by the International Financial Reporting Standards in the rest of the world. These institutions provide detailed guidelines on the treatment of Asset Retirement Obligations.

For the right measurement of the liability, the company must determine the fair value of the liability when it incurs it. If the fair value of the liability cannot be determined, the liability should be recognized at a later date when the fair value becomes available. Prompt recognition of the liability can be beneficial for stakeholders as these liabilities are high-value liabilities, and their recognition shows a better picture of the liabilities.

The increase in liability is recognized as accretion expense on the income statement and is calculated by multiplying the liability amount by the risk-free rate. Any change in the expected expense is adjusted to the liability balance after every revision. The asset recognized on the balance sheet is depreciated, and the expense is recorded on the income statement.

Assume a power company builds a power plant at a site with a 50-year lease. The asset takes 3 years to be built and has to be necessarily retired at the end of 47 years after it was built. The cost of dismantling the equipment, detoxification of the site, and cleaning of the site is $50,000 in today’s dollars. Because retirement has to be done after 47 years, this cost will be higher at that time. To consider that, the retirement cost will increase at the rate of inflation. Assuming an inflation rate of 3%, the cost of retirement at the end of 47 years will be $200,595. Assuming a risk-free rate of 7%, the present value of this obligation comes out to be $8.342. See the illustration below for details.
