Impairment, Asset Retirement Obligation

Impairment

In accounting, the decrease in the net asset value of an asset due to the carrying amount of the asset exceeding the recoverable amount thereof. The effect of impairment constitutes the decrease in asset values per the Statement of Financial Position and a corresponding amount recognised through profit or loss in respect of the impairment loss.

Impairment describes a permanent reduction in the value of a company’s asset, typically a fixed asset or an intangible asset. When testing an asset for impairment, the total profit, cash flow, or other benefit expected to be generated by that specific asset is periodically compared with its current book value. If it is determined that the book value of the asset exceeds the future cash flow or benefit of the asset, the difference between the two is written off and the value of the asset declines on the company’s balance sheet.

Impairment is commonly used to describe a drastic reduction in the recoverable amount of a fixed asset. Impairment may occur when there is a change in legal or economic circumstances surrounding a company or a casualty loss from unforeseen devastation.

Factors could lead to the value of the asset declining:

Change in legal climate: It’s also possible that a lawsuit, court case, or some other change to the general business/legal climate could cause a reduction in value of the asset. For example, if a worker gets injured while using your equipment and sues your company, you may not be able to use the asset until the legal situation is resolved.

Market downturn: If the market takes a dip, then the fair market value of an asset may end up being less than its book value. For example, if the real estate market experiences a downturn, then any land or property that you’re holding as an asset could decline in value.

Escalating costs: You may experience a situation where the running costs to maintain an asset are more than you were expecting when you made the initial investment, or the running costs have simply escalated over time, leading to a reduction in overall value.

Impairment vs. Depreciation and Amortization

Impairment of assets may sound similar to the accounting processes of depreciation and amortization (a reduction in the value of an asset over the course of its useful life). While there are some relatively clear similarities between the two concepts, there’s one key distinction: impairment denotes a sudden, irreversible drop in value, whereas depreciation/amortisation reduces the value of the asset over its entire lifetime. So, whereas impairment accounts for unusual drops in an asset’s value, depreciation and amortisation is generally used for standard wear and tear.

Fixed assets, such as machinery and equipment, depreciate in value over time. The amount of depreciation taken each accounting period is based on a predetermined schedule using either straight line or one of multiple accelerated depreciation methods. Depreciation schedules allow for a set distribution of the reduction of an asset’s value over its entire lifetime. Unlike impairment, which accounts for an unusual and drastic drop in the fair value of an asset, depreciation is used to account for typical wear and tear on fixed assets over time.

Asset Retirement Obligation

An Asset Retirement Obligation (ARO) is a legal obligation associated with the retirement of a tangible long-lived asset in which the timing or method of settlement may be conditional on a future event, the occurrence of which may not be within the control of the entity burdened by the obligation. In the United States, ARO accounting is specified by Statement of Financial Accounting Standards (SFAS, or FAS) 143, which is Topic 410-20 in the Accounting Standards Codification published by the Financial Accounting Standards Board. Entities covered by International Financial Reporting Standards (IFRS) apply a standard called IAS 37 to AROs, where the AROs are called “provisions”. ARO accounting is particularly significant for remediation work needed to restore a property, such as decontaminating a nuclear power plant site, removing underground fuel storage tanks, cleanup around an oil well, or removal of improvements to a site. It does not apply to unplanned cleanup costs, such as costs incurred as a result of an accident.

Firms must recognize the ARO liability in the period in which it was incurred, such as at the time of acquisition or construction. The liability equals the present value of the expected cost of retirement/remediation. An asset equal to the initial liability is added to the balance sheet, and depreciated over the life of the asset. The result is an increase in both assets and liabilities, while the total expected cost is recognized over time, with the accrual steadily increasing on a compounded basis.

An asset retirement obligation (ARO) is a legal obligation that is associated with the retirement of a tangible, long-term asset. It is generally applicable when a company is responsible for removing equipment or cleaning up hazardous materials at some agreed-upon future date.

The purpose of asset retirement obligations is to act as a fair value of a legal obligation that a company undertook when it installed infrastructure assets that must be dismantled in the future (along with remediation efforts to restore their original state). The fair value of the ARO must be recognized immediately, so the present financial position of the company is not distorted; however, it must be done reliably.

AROs ensure that known future problems are planned for and resolved. In the real world, they are utilized mainly by companies that typically use infrastructure in their operations. A good example is oil and gas companies.

Calculating AROs

When a company installs a long-term asset with future intentions of removing it, it incurs an ARO. To recognize the obligation’s fair value, CPAs use a variety of methods; however, the most common is to use the expected present value technique. To use the expected present value  technique, you will need the following:

• Discount Rate

Acquire a credit-adjusted, risk-free rate to discount the cash flows to their present value. The credit rating of a business may affect the discount rate.

• Probability Distribution

When calculating the expected values, we need to know the probability of certain events occurring. For example, if there are only two possible outcomes, then you can assume that each outcome comes with a 50% probability of happening. It is recommended you use the probability distribution method unless other information must be considered.

To calculate the expected present value of an ARO, companies should observe the following iterative steps:

• Estimate the timing and cash flows of retirement activities.
• Calculate the credit-adjusted risk-free rate.
• Note any increase in the carrying amount of the ARO liability as an accretion expense by multiplying the beginning liability by the credit-adjusted risk-free rate for when the liability was first measured.
• Note whether liability revisions are trending upward, then discount them at the current credit-adjusted risk-free rate.
• Note whether liability revisions are trending downward, then discount the reduction at the rate used for the initial recognition of the related liability year.
