## Machine-generated topic summary

ASC 410 covers two distinct kinds of retirement/cleanup obligations. Subtopic 410-20 requires an entity to recognize, at fair value in the period incurred, a legal obligation to retire a tangible long-lived asset arising from its acquisition, construction, development, or normal operation, and to capitalize an equal asset retirement cost in the asset's carrying amount, with later accretion (credit-adjusted risk-free rate) and revisions to estimated cash flows (410-20-25-4; 410-20-25-5; 410-20-30-1; 410-20-35-3). Subtopic 410-30 instead applies the ASC 450-20 loss contingency model site by site to environmental remediation liabilities under CERCLA, RCRA, and analogous laws, accruing the entity's allocable share of joint and several liability when a loss is probable and reasonably estimable and expensing it in operating income, with separate recognition of probable recoveries. ASC 410-10 is purely navigational (410-10-05-2), and 410-980 adds regulatory asset/liability treatment for rate-regulated entities whose rate recovery of retirement costs differs in timing from GAAP cost recognition (410-980-25-2). The unifying idea: a retirement obligation is recognized up front at fair value and capitalized into the asset, whereas a remediation obligation from past contamination is a contingency expensed as incurred.

The Asset [Retirement](https://asc.understandingaccounting.org/glossary/r/#retirement "The other-than-temporary removal of a long-lived asset from service. That term encompasses sale, abandonment, recycling, or disposal in some other manner. However, it does not encompass the temporary idling of a long-lived asset. After an entity retires an asset, that asset is no longer under the control of that entity, no longer in existence, or no longer capable of being used in the manner for which the asset was originally acquired, constructed, or developed.") and Environmental Obligations Topic includes the following Subtopics:

The sole purpose of the Overall Subtopic is to explain the differences between the other two Subtopics. Subtopic 410-20 provides guidance on accounting for and financial reporting of a liability for an asset retirement obligation (and the associated asset retirement cost) and an environmental remediation liability that results from the normal operation of a long-lived asset (see paragraph [410-20-55-7](https://asc.understandingaccounting.org/asc/410/20/#410-20-55-7)). Subtopic 410-30 provides guidance on accounting for and financial reporting of environmental remediation liabilities.

## ASC 410-20: Asset Retirement and Environmental Obligations — Asset Retirement Obligations

### Machine-generated study aids

```json
{
  "summary": "ASC 410-20 governs legal obligations associated with the retirement of tangible long-lived assets that arise from acquisition, construction, development, and/or normal operation of the asset, including environmental remediation resulting from normal operations. An entity recognizes the fair value of the ARO liability in the period incurred if fair value can be reasonably estimated, and simultaneously capitalizes an equal asset retirement cost in the carrying amount of the related long-lived asset (410-20-25-4; 410-20-25-5). Fair value is normally measured with an expected present value technique discounted at a credit-adjusted risk-free rate, with later changes recognized as accretion expense and as revisions to estimated cash flows (410-20-30-1; 410-20-35-3).",
  "key_points": [
    "An entity recognizes an ARO at fair value in the period incurred if a reasonable estimate can be made; otherwise recognition is deferred until a reasonable estimate is possible, and an ARO on an acquired asset is recognized at the acquisition date as if incurred then (410-20-25-4; 410-20-25-16).",
    "Upon initial recognition, the entity capitalizes an asset retirement cost by increasing the carrying amount of the related long-lived asset by the same amount as the liability, and allocates that cost to expense over the asset's useful life using a systematic and rational method (410-20-25-5; 410-20-35-2).",
    "A conditional ARO must be recognized before the event requiring or waiving performance occurs; the obligation to stand ready is unconditional, and uncertainty about timing/method and about whether performance will be enforced affects measurement, not recognition (410-20-25-7; 410-20-25-13 through 25-15); when the conditional aspect has two outcomes and no information on which is more probable, 50 percent is used for each (410-20-25-14).",
    "Fair value is usually measured with an expected present value technique, discounting expected cash flows (including third-party costs, overhead, profit margin, inflation, and a market-risk premium) at a credit-adjusted risk-free rate (410-20-30-1; 410-20-55-13).",
    "Subsequent changes arise from (a) passage of time, measured by the interest method using the credit-adjusted risk-free rate in effect when that layer was initially measured and recognized as accretion expense (an operating item), and (b) revisions to timing or amount of undiscounted cash flows, measured before which accretion must first be recorded (410-20-35-3 through 35-5; 410-20-45-1).",
    "Upward revisions in undiscounted estimated cash flows are discounted at the current credit-adjusted risk-free rate; downward revisions are discounted at the rate that existed when the original liability was recognized (or a weighted-average rate if the layer cannot be identified) (410-20-35-8).",
    "Required disclosures include a description of the AROs and related assets, the fair value of assets legally restricted for settling AROs, and a reconciliation of the beginning and ending carrying amount showing liabilities incurred, liabilities settled, accretion expense, and revisions in estimated cash flows; if fair value cannot be reasonably estimated, that fact and the reasons must be disclosed (410-20-50-1; 410-20-50-2)."

This Subtopic establishes accounting standards for recognition and measurement of a liability for an [asset retirement obligation](https://asc.understandingaccounting.org/glossary/a/#asset-retirement-obligation "An obligation associated with the retirement of a tangible long-lived asset.") and the associated [asset retirement cost](https://asc.understandingaccounting.org/glossary/a/#asset-retirement-cost "The amount capitalized that increases the carrying amount of the long-lived asset when a liability for an asset retirement obligation is recognized."). This Subtopic also addresses the accounting for an environmental remediation liability that results from the normal operation of a long-lived asset.

Effective as of: not established by retrieval timestamps.


The guidance in this Subtopic applies to the following transactions and activities:

1.  a
    
    [Legal obligations](https://asc.understandingaccounting.org/glossary/l/#legal-obligation "An obligation that a party is required to settle as a result of an existing or enacted law, statute, ordinance, or written or oral contract or by legal construction of a contract under the doctrine of promissory estoppel.") associated with the [retirement](https://asc.understandingaccounting.org/glossary/r/#retirement "The other-than-temporary removal of a long-lived asset from service. That term encompasses sale, abandonment, recycling, or disposal in some other manner. However, it does not encompass the temporary idling of a long-lived asset. After an entity retires an asset, that asset is no longer under the control of that entity, no longer in existence, or no longer capable of being used in the manner for which the asset was originally acquired, constructed, or developed.")of a tangible long-lived asset that result from the acquisition, construction, or development and (or) the normal operation of a long-lived asset, including any legal obligations that require [disposal](https://asc.understandingaccounting.org/glossary/d/#disposal "Related to the Comprehensive Environmental Response, Compensation, and Liability Act of 1980 and the Resource Conservation and Recovery Act of 1976: under the Resource Conservation and Recovery Act of 1976, the discharge, deposit, injection, dumping, spilling, leaking, or placing of any solid waste or hazardous waste into or on any land or water so that such solid waste or hazardous waste or any constituent thereof may enter the environment or be emitted into the air or discharged into any waters, including groundwaters. Similarly under the Comprehensive Environmental Response, Compensation, and Liability Act of 1980 with regard to hazardous substances.") of a replaced part that is a component of a tangible long-lived asset.
    
2.  b
    
    An environmental remediation liability that results from the normal operation of a long-lived asset and that is associated with the retirement of that asset. The fact that partial settlement of an obligation is required or performed before full retirement of an asset does not remove that obligation from the scope of this Subtopic. If environmental contamination is incurred in the normal operation of a long-lived asset and is associated with the retirement of that asset, then this Subtopic will apply (and Subtopic 410-30 will not apply) if the entity is legally obligated to treat the contamination.
    
3.  c
    
    A conditional obligation to perform a retirement activity. Uncertainty about the timing of settlement of the [asset retirement obligation](https://asc.understandingaccounting.org/glossary/a/#asset-retirement-obligation "An obligation associated with the retirement of a tangible long-lived asset.") does not remove that obligation from the scope of this Subtopic but will affect the measurement of a liability for that obligation (see paragraph [410-20-25-10](https://asc.understandingaccounting.org/asc/410/20/#410-20-25-10)).
    
4.  d
    
    Obligations of a [lessor](https://asc.understandingaccounting.org/glossary/l/#lessor "An entity that enters into a contract to provide the right to use an underlying asset for a period of time in exchange for consideration.") in connection with an [underlying asset](https://asc.understandingaccounting.org/glossary/u/#underlying-asset "An asset that is the subject of a lease for which a right to use that asset has been conveyed to a lessee. The underlying asset could be a physically distinct portion of a single asset.") that meet the provisions in (a).
    
5.  e
    
    The costs associated with the retirement of a specified asset that qualifies as historical waste equipment as defined by EU Directive 2002/96/EC. (See paragraphs
    
    [410-20-55-23 through 55-30](https://asc.understandingaccounting.org/asc/410/20/#410-20-55-23)
    
    and Example 4 \[paragraph [410-20-55-63](https://asc.understandingaccounting.org/asc/410/20/#410-20-55-63)\] for illustration of this guidance.) Paragraph [410-20-55-24](https://asc.understandingaccounting.org/asc/410/20/#410-20-55-24) explains how the Directive distinguishes between new and historical waste and provides related implementation guidance.

The guidance in this Subtopic does not apply to the following transactions and activities:

1.  a
    
    Obligations that arise solely from a plan to sell or otherwise dispose of a long-lived asset covered by Subtopic 360-10.
    
2.  b
    
    An environmental remediation liability that results from the improper operation of a long-lived asset (see Subtopic 410-30). Obligations resulting from improper operations do not represent costs that are an integral part of the tangible long-lived asset and therefore should not be accounted for as part of the cost basis of the asset. For example, a certain amount of spillage may be inherent in the normal operations of a fuel storage facility, but a catastrophic accident caused by noncompliance with an entity's safety procedures is not. The obligation to clean up the spillage resulting from the normal operation of the fuel storage facility is within the scope of this Subtopic. The obligation to clean up after the catastrophic accident results from the improper use of the facility and is not within the scope of this Subtopic.
    
3.  c
    
    Activities necessary to prepare an asset for an alternative use as they are not associated with the retirement of the asset.
    
4.  d
    
    Historical waste held by private households. (The guidance in this paragraph does not pertain to an asset retirement obligation in the scope of this Subtopic.) For guidance on accounting for historical electronic equipment waste held by private households for obligations associated with Directive 2002/96/EC on Waste Electrical and Electronic Equipment adopted by the European Union, see Subtopic 720-40.
    
5.  e
    
    Obligations of a [lessee](https://asc.understandingaccounting.org/glossary/l/#lessee "An entity that enters into a contract to obtain the right to use an underlying asset for a period of time in exchange for consideration.") in connection with an [underlying asset](https://asc.understandingaccounting.org/glossary/u/#underlying-asset "An asset that is the subject of a lease for which a right to use that asset has been conveyed to a lessee. The underlying asset could be a physically distinct portion of a single asset."), whether imposed by a [lease](https://asc.understandingaccounting.org/glossary/l/#lease "A contract, or part of a contract, that conveys the right to control the use of identified property, plant, or equipment (an identified asset) for a period of time in exchange for consideration.") or by a party other than the lessor, that meet the definition of either [lease payments](https://asc.understandingaccounting.org/glossary/l/#lease-payments "See paragraph 842-10-30-5 for what constitutes lease payments from the perspective of a lessee and a lessor.") or [variable lease payments](https://asc.understandingaccounting.org/glossary/v/#variable-lease-payments "Payments made by a lessee to a lessor for the right to use an underlying asset that vary because of changes in facts or circumstances occurring after the commencement date, other than the passage of time.") in Subtopic 842-10. Those obligations shall be accounted for by the lessee in accordance with the requirements of Subtopic 842-10. However, if obligations of a lessee in connection with an underlying asset, whether imposed by a lease or by a party other than the lessor, meet the provisions in paragraph [410-20-15-2](https://asc.understandingaccounting.org/asc/410/20/#410-20-15-2) but do not meet the definition of either lease payments or variable lease payments in Subtopic 842-10, those obligations shall be accounted for by the lessee in accordance with the requirements of this Subtopic.
    
6.  f
    
    An obligation for asbestos removal that results from the other-than-normal operation of an asset. Such an obligation may be subject to the provisions of Subtopic 410-30.
    
7.  g
    
    Costs associated with complying with funding or assurance provisions. Paragraph [410-20-35-9](https://asc.understandingaccounting.org/asc/410/20/#410-20-35-9) otherwise addresses the measurement effects of funding and assurance provisions.
    
8.  h
    
    Obligations associated with maintenance, rather than retirement, of a long-lived asset.
    
9.  i
    
    The cost of a replacement part that is a component of a long-lived asset.

Probable is used with its usual general meaning, rather than in a specific accounting or technical sense (such as that in paragraph [450-20-25-1](https://asc.understandingaccounting.org/asc/450/20/#450-20-25-1)), and refers to that which can reasonably be expected or believed on the basis of available evidence or logic but is neither certain nor proved (Webster's New World Dictionary). Its inclusion in the definition is intended to acknowledge that business and other economic activities occur in an environment characterized by uncertainty in which few outcomes are certain (see paragraphs 44 through 48 of FASB Concepts Statement No. 6).

As stated in the preceding paragraph, the definition of a liability in Concepts Statement 6 uses the term _probable_ in a different sense than it is used in paragraph [450-20-25-1](https://asc.understandingaccounting.org/asc/450/20/#450-20-25-1). As used in Topic 450, probable requires a high degree of expectation. The term probable in the definition of a liability, however, is intended to acknowledge that business and other economic activities occur in an environment in which few outcomes are certain.

An entity shall identify all its asset retirement obligations. An entity has sufficient information to reasonably estimate the fair value of an asset retirement obligation if any of the following conditions exist:

The obligation to perform the asset retirement activity is unconditional even though uncertainty exists about the timing and (or) method of settlement. Thus, the timing and (or) method of settlement may be conditional on a future event. Accordingly, an entity shall recognize a liability for the fair value of a [conditional asset retirement obligation](https://asc.understandingaccounting.org/glossary/c/#conditional-asset-retirement-obligation "A legal obligation to perform an asset retirement activity in which the timing and (or) method of settlement are conditional on a future event that may or may not be within the control of the entity.") if the fair value of the liability can be reasonably estimated. In some cases, sufficient information about the timing and (or) method of settlement may not be available to reasonably estimate fair value. An expected present value technique incorporates uncertainty about the timing and method of settlement into the fair value measurement. Uncertainty is factored into the measurement of the fair value of the liability through assignment of probabilities to cash flows.

An entity would have sufficient information to apply an expected present value technique and therefore an asset retirement obligation would be reasonably estimable if either of the following conditions exists:

1.  a
    
    The settlement date and method of settlement for the obligation have been specified by others. For example, the law, regulation, or contract that gives rise to the [legal obligation](https://asc.understandingaccounting.org/glossary/l/#legal-obligation "An obligation that a party is required to settle as a result of an existing or enacted law, statute, ordinance, or written or oral contract or by legal construction of a contract under the doctrine of promissory estoppel.") specifies the settlement date and method of settlement. In this situation, the settlement date and method of settlement are known and therefore the only uncertainty is whether the obligation will be enforced (that is, whether performance will be required). In certain cases, determining the settlement date for the obligation that has been specified by others is a matter of judgment that depends on the relevant facts and circumstances. For example, a contract that provides the entity with an ability to extend its term through renewal should be evaluated to determine whether the settlement date should take into consideration renewal periods. Uncertainty about whether performance will be required does not defer the recognition of an asset retirement obligation because a legal obligation to stand ready to perform the retirement activities still exists, and it does not prevent the determination of a reasonable estimate of fair value because the only uncertainty is whether performance will be required.
    
2.  b
    
    The information is available to reasonably estimate all of the following:
    
    1.  1
        
        The settlement date or the range of potential settlement dates
        
    2.  2
        
        The method of settlement or potential methods of settlement (The term _potential methods of settlement_ refers to methods of settling the obligation that are currently available to the entity. Therefore, uncertainty about future methods yet to be developed would not prevent the entity from estimating the fair value of the asset retirement obligation.)
        
    3.  3
        
        The probabilities associated with the potential settlement dates and potential methods of settlement. (The entity should have a reasonable basis for assigning probabilities to the potential settlement dates and potential methods of settlement to reasonably estimate the fair value of the asset retirement obligation. If the entity does not have a reasonable basis of assigning probabilities, it is expected that the entity would still be able to reasonably estimate fair value when the range of time over which the entity may settle the obligation is so narrow and (or) the cash flows associated with each potential method of settlement are so similar that assigning probabilities without having a reasonable basis for doing so would not have a material impact on the fair value of the asset retirement obligation.)

In many cases, the determination as to whether the entity has the information to reasonably estimate the fair value of the asset retirement obligation is a matter of judgment that depends on the relevant facts and circumstances. It is expected that the narrower the range of time over which the entity may settle the obligation and the fewer potential methods of settlement the entity has available to it, the more likely it is that the entity will have the information to reasonably estimate the fair value of an asset retirement obligation. For an illustration of this guidance, see Example 3 (paragraph [410-20-55-47](https://asc.understandingaccounting.org/asc/410/20/#410-20-55-47)).

Instances may occur in which sufficient information to estimate the fair value of an asset retirement obligation is unavailable. For example, if an asset has an indeterminate useful life, sufficient information to estimate a range of potential settlement dates for the obligation might not be available. In such cases, the liability would be initially recognized in the period in which sufficient information exists to estimate a range of potential settlement dates that is needed to employ a present value technique to estimate fair value.

Examples of information that is expected to provide a basis for estimating the potential settlement dates, potential methods of settlement, and the associated probabilities include, but are not limited to, information that is derived from the entity's past practice, industry practice, management's intent, or the asset's estimated economic life. The estimated economic life of the asset might indicate a potential settlement date for the asset retirement obligation. However, the original estimated economic life of the asset may not, in and of itself, establish that date because the entity may intend to make improvements to the asset that could extend the life of the asset or the entity could defer settlement of the obligation beyond the economic life of the asset. In those situations, the entity would look beyond the economic life of the asset in determining the settlement date or range of potential settlement dates to use when estimating the fair value of the asset retirement obligation.

If a current law, regulation, or contract requires an entity to perform an asset retirement activity when an asset is dismantled or demolished, there is an unambiguous requirement to perform the retirement activity even if that activity can be indefinitely deferred. At some time deferral will no longer be possible, because no tangible asset will last forever (except land). Therefore, the obligation to perform the asset retirement activity is unconditional even though uncertainty exists about the timing and (or) method of settlement.

This Subtopic requires recognition of a conditional asset retirement obligation before the event that either requires or waives performance occurs. Uncertainty surrounding conditional performance of the retirement obligation is factored into its measurement by assessing the likelihood that performance will be required.

An unambiguous requirement that gives rise to an asset retirement obligation coupled with a low likelihood of required performance still requires recognition of a liability. Uncertainty about the conditional outcome of the obligation is incorporated into the measurement of the fair value of that liability, not the recognition decision. Uncertainty about performance of conditional obligations shall not prevent the determination of a reasonable estimate of fair value. A past history of nonenforcement of an unambiguous obligation does not defer recognition of a liability, but its measurement is affected by the uncertainty over the requirement to perform retirement activities.

An expected present value technique will usually be the only appropriate technique with which to estimate the fair value of a liability for an [asset retirement obligation](https://asc.understandingaccounting.org/glossary/a/#asset-retirement-obligation "An obligation associated with the retirement of a tangible long-lived asset."). An entity, when using that technique, shall discount the expected cash flows using a credit-adjusted risk-free rate. Thus, the effect of an entity's credit standing is reflected in the discount rate rather than in the expected cash flows. Proper application of a [discount rate adjustment technique](https://asc.understandingaccounting.org/glossary/d/#discount-rate-adjustment-technique "A present value technique that uses a risk-adjusted discount rate and contractual, promised, or most likely cash flows.") entails analysis of at least two liabilities—the liability that exists in the marketplace and has an observable interest rate and the liability being measured. The appropriate rate of interest for the cash flows being measured shall be inferred from the observable rate of interest of some other liability, and to draw that inference the characteristics of the cash flows shall be similar to those of the liability being measured. Rarely, if ever, would there be an observable rate of interest for a liability that has cash flows similar to an asset retirement obligation being measured. In addition, an asset retirement obligation usually will have uncertainties in both timing and amount. In that circumstance, employing a discount rate adjustment technique, where uncertainty is incorporated into the rate, will be difficult, if not impossible. See paragraphs

[410-20-55-13 through 55-17](https://asc.understandingaccounting.org/asc/410/20/#410-20-55-13)

A liability for an [asset retirement obligation](https://asc.understandingaccounting.org/glossary/a/#asset-retirement-obligation "An obligation associated with the retirement of a tangible long-lived asset.") may be incurred over more than one reporting period if the events that create the obligation occur over more than one reporting period.

An entity shall subsequently allocate that [asset retirement cost](https://asc.understandingaccounting.org/glossary/a/#asset-retirement-cost "The amount capitalized that increases the carrying amount of the long-lived asset when a liability for an asset retirement obligation is recognized.") to expense using a systematic and rational method over its useful life. Application of a systematic and rational allocation method does not preclude an entity from capitalizing an amount of asset retirement cost and allocating an equal amount to expense in the same accounting period. For example, assume an entity acquires a long-lived asset with an estimated life of 10 years. As that asset is operated, the entity incurs one-tenth of the liability for an asset retirement obligation each year. Application of a systematic and rational allocation method would not preclude that entity from capitalizing and then expensing one-tenth of the asset retirement costs each year.

An entity shall measure changes in the liability for an asset retirement obligation due to passage of time by applying an interest method of allocation to the amount of the liability at the beginning of the period.

The subsequent measurement provisions require an entity to identify undiscounted estimated cash flows associated with the initial measurement of a liability. Therefore, an entity that obtains an initial measurement of fair value from a market price or from a technique other than an expected present value technique must determine the undiscounted cash flows and estimated timing of those cash flows that are embodied in that fair value amount for purposes of applying the subsequent measurement provisions. Example 1 (see paragraph [410-20-55-31](https://asc.understandingaccounting.org/asc/410/20/#410-20-55-31)) provides an illustration of the subsequent measurement of a liability that is initially obtained from a market price.

Paragraph [410-20-25-14](https://asc.understandingaccounting.org/asc/410/20/#410-20-25-14) explains how uncertainty surrounding conditional performance of a retirement obligation is factored into its measurement by assessing the likelihood that performance will be required. As the time for notification approaches, more information and a better perspective about the ultimate outcome will likely be obtained. Consequently, reassessment of the timing, amount, and probabilities associated with the expected cash flows may change the amount of the liability recognized. See paragraphs

Changes resulting from revisions to the timing or the amount of the original estimate of undiscounted cash flows shall be recognized as an increase or a decrease in the carrying amount of the liability for an asset retirement obligation and the related asset retirement cost capitalized as part of the carrying amount of the related long-lived asset. Upward revisions in the amount of undiscounted estimated cash flows shall be discounted using the current credit-adjusted risk-free rate. Downward revisions in the amount of undiscounted estimated cash flows shall be discounted using the credit-adjusted risk-free rate that existed when the original liability was recognized. If an entity cannot identify the prior period to which the downward revision relates, it may use a weighted-average credit-adjusted risk-free rate to discount the downward revision to estimated future cash flows. When asset retirement costs change as a result of a revision to estimated cash flows, an entity shall adjust the amount of asset retirement cost allocated to expense in the period of change if the change affects that period only or in the period of change and future periods if the change affects more than one period as required by paragraphs

Methods of providing assurance include surety bonds, insurance policies, letters of credit, guarantees by other entities, and establishment of trust funds or identification of other assets dedicated to satisfy the asset retirement obligation. The existence of funding and assurance provisions may affect the determination of the credit-adjusted risk-free rate. For a previously recognized asset retirement obligation, changes in funding and assurance provisions have no effect on the initial measurement or accretion of that liability, but may affect the credit-adjusted risk-free rate used to discount upward revisions in undiscounted cash flows for that obligation.

Typically, settlement of an [asset retirement obligation](https://asc.understandingaccounting.org/glossary/a/#asset-retirement-obligation "An obligation associated with the retirement of a tangible long-lived asset.") is not required until the associated asset is retired. However, certain circumstances may exist in which partial settlement of an asset retirement obligation is required or performed before the asset is fully retired. The nature of asset retirement obligations in various industries is such that the obligations are not necessarily satisfied when the current operation or use of the asset ceases. These obligations can be settled during operation of the asset or after the operations cease. The timing of the ultimate settlement of a liability is unrelated to and should not affect its initial recognition in the financial statements provided the obligation is associated with the [retirement](https://asc.understandingaccounting.org/glossary/r/#retirement "The other-than-temporary removal of a long-lived asset from service. That term encompasses sale, abandonment, recycling, or disposal in some other manner. However, it does not encompass the temporary idling of a long-lived asset. After an entity retires an asset, that asset is no longer under the control of that entity, no longer in existence, or no longer capable of being used in the manner for which the asset was originally acquired, constructed, or developed.") of a tangible long-lived asset.

Providing assurance that an entity will be able to satisfy its asset retirement obligation does not satisfy or extinguish the related liability. The effect of surety bonds, letters of credit, and guarantees is to provide assurance that third parties will provide amounts to satisfy the asset retirement obligations if the entity that has primary responsibility (the obligor) to do so cannot or does not fulfill its obligations. The possibility that a third party will satisfy the asset retirement obligations does not relieve the obligor from its primary responsibility for those obligations. If a third party is required to satisfy asset retirement obligations due to the failure or inability of the obligor to do so directly, the obligor would then have a liability to the third party.

This implementation guidance illustrates Section 410-20-15. In most cases involving an [asset retirement obligation](https://asc.understandingaccounting.org/glossary/a/#asset-retirement-obligation "An obligation associated with the retirement of a tangible long-lived asset."), the determination of whether a [legal obligation](https://asc.understandingaccounting.org/glossary/l/#legal-obligation "An obligation that a party is required to settle as a result of an existing or enacted law, statute, ordinance, or written or oral contract or by legal construction of a contract under the doctrine of promissory estoppel.") exists should be unambiguous. However, in situations in which no law, statute, ordinance, or contract exists but an entity makes a promise to a third party (which may include the public at large) about its intention to perform [retirement](https://asc.understandingaccounting.org/glossary/r/#retirement "The other-than-temporary removal of a long-lived asset from service. That term encompasses sale, abandonment, recycling, or disposal in some other manner. However, it does not encompass the temporary idling of a long-lived asset. After an entity retires an asset, that asset is no longer under the control of that entity, no longer in existence, or no longer capable of being used in the manner for which the asset was originally acquired, constructed, or developed.") activities, facts and circumstances need to be considered carefully in determining whether that promise has imposed a legal obligation upon the promisor under the doctrine of [promissory estoppel](https://asc.understandingaccounting.org/glossary/p/#promissory-estoppel "\"The principle that a promise made without consideration may nonetheless be enforced to prevent injustice if the promisor should have reasonably expected the promisee to rely on the promise and if the promisee did actually rely on the promise to his or her detriment.\" (See Black's Law Dictionary, seventh edition.)"). A legal obligation may exist even though no party has taken any formal action. In assessing whether a legal obligation exists, an entity is not permitted to forecast changes in the law or changes in the interpretation of existing laws and regulations. Preparers and their legal advisors are required to evaluate current circumstances to determine whether a legal obligation exists.

For example, assume an entity operates a manufacturing facility and has plans to retire it within five years. Members of the local press have begun to publicize the fact that when the entity ceases operations at the plant, it plans to abandon the site without demolishing the building and restoring the underlying land. Due to the significant negative publicity and demands by the public that the entity commit to dismantling the plant upon retirement, the entity's chief executive officer holds a press conference at city hall to announce that the entity will demolish the building and restore the underlying land when the entity ceases operations at the plant. Although no law, statute, ordinance, or written contract exists requiring the entity to perform any demolition or restoration activities, the promise made by the entity's chief executive officer may have created a legal obligation under the doctrine of promissory estoppel. In that circumstance, the entity's management (and legal counsel, if necessary) would have to evaluate the particular facts and circumstances to determine whether a legal obligation exists.

Once an entity determines that a duty or responsibility exists, it will then need to assess whether an obligating event has occurred that leaves it little or no discretion to avoid the future transfer or use of assets. If such an obligating event has occurred, an asset retirement obligation meets the definition of a liability and qualifies for recognition in the financial statements. However, if an obligating event that leaves an entity little or no discretion to avoid the future transfer or use of assets has not occurred, an asset retirement obligation does not meet the definition of a liability and, therefore, should not be recognized in the financial statements.

Identifying the obligating event is often difficult, especially in situations that involve the occurrence of a series of transactions or other events or circumstances affecting the entity. For example, in the case of an asset retirement obligation, a law or an entity's promise may create a duty or responsibility, but that law or promise in and of itself may not be the obligating event that results in an entity's having little or no discretion to avoid a future transfer or use of assets. An entity must look to the nature of the duty or responsibility to assess whether the obligating event has occurred. For example, in the case of a nuclear power facility, an entity assumes responsibility for decontamination of that facility upon receipt of the license to operate it. However, no obligation to decontaminate exists until the facility is operated and contamination occurs. Therefore, the contamination, not the receipt of the license, constitutes the obligating event.

This implementation guidance illustrates Section 410-20-15. Contracts between entities may contain an option or a provision that requires one party to the contract to perform retirement activities when an asset is retired. The other party may decide in the future not to exercise the option or to waive the provision to perform retirement activities, or that party may have a history of waiving similar provisions in other contracts. Even if there is an expectation of a waiver or nonenforcement, the contract still imposes a legal obligation. That obligation is included in the scope of this Subtopic. The likelihood of a waiver or nonenforcement will affect the measurement of the liability. For example, consider an entity that owns and operates a landfill. Regulations require that that entity perform capping, [closure](https://asc.understandingaccounting.org/glossary/c/#closure "Related to the Resource Conservation and Recovery Act of 1976: the process in which the owner-operator of a hazardous waste management unit discontinues active operation of the unit by treating, removing from the site, or disposing of on site all hazardous wastes in accordance with an Environmental Protection Agency or state-approved plan. Included, for example, are the process of emptying, cleaning, and removing or filling underground storage tanks and the capping of a landfill. Closure entails specific financial guarantees and technical tasks that are included in a closure plan and must be implemented."), and postclosure activities. Capping activities involve covering the land with topsoil and planting vegetation. Closure activities include drainage, engineering, and demolition and must be performed prior to commencing the postclosure activities. Postclosure activities, the final retirement activities, include maintaining the landfill once final certification of closure has been received and monitoring the ground and surface water, gas emissions, and air quality. Closure and postclosure activities are performed after the entire landfill ceases receiving waste (that is, after the landfill is retired). However, capping activities are performed as sections of the landfill become full and are effectively retired. The fact that some of the capping activities are performed while the landfill continues to accept waste does not remove the obligation to perform those intermediate capping activities from the scope of this Subtopic.

This implementation guidance illustrates Section 410-20-15. Whether an obligation results from the acquisition, construction, or development of a long-lived asset should, in most circumstances, be clear. For example, if an entity acquires a landfill that is already in operation, an obligation to perform capping, closure, and postclosure activities results from the acquisition and assumption of obligations related to past normal operations of the landfill. Additional obligations will be incurred as a result of future operations of the landfill.

This implementation guidance illustrates Section 410-20-15. Whether an obligation results from the normal operation of a long-lived asset may require judgment. Obligations that result from the normal operation of an asset should be predictable and likely of occurring. For example, consider an entity that owns and operates a nuclear power plant. That entity has a legal obligation to perform decontamination activities when the plant ceases operations. Contamination, which gives rise to the obligation, is predictable and likely of occurring and is unavoidable as a result of operating the plant. Therefore, the obligation to perform decontamination activities at that plant results from the normal operation of the plant.

For example, a certain amount of spillage may be inherent in the normal operations of a fuel storage facility, but a catastrophic accident caused by noncompliance with an entity's safety procedures is not. The obligation to clean up after the catastrophic accident does not result from the normal operation of the facility and is not within the scope of this Subtopic.

For example, consider an aluminum smelter that owns and operates several kilns lined with a special type of brick. The kilns have a long useful life, but the bricks wear out after approximately five years of use and are replaced on a periodic basis to maintain optimal efficiency of the kilns. Because the bricks become contaminated with hazardous chemicals while in the kiln, a state law requires that when the bricks are removed, they must be disposed of at a special [hazardous waste](https://asc.understandingaccounting.org/glossary/h/#hazardous-waste "Related to Resource Conservation and Recovery Act of 1976: a waste, or combination of wastes, that because of its quantity, concentration, toxicity, corrosiveness, mutagenicity or inflammability, or physical, chemical, or infectious characteristics may cause, or significantly contribute to, an increase in mortality or an increase in serious irreversible, or incapacitating reversible illness or pose a substantial present or potential hazard to human health or the environment when improperly treated, stored, transported, or disposed of, or otherwise managed. Technically, those wastes that are regulated under the Resource Conservation and Recovery Act of 1976 40 CFR Part 261 are considered to be hazardous wastes.") site.

If assets with asset retirement obligations are components of a larger group of assets (for example, a number of oil wells that make up an entire oil field operation), aggregation techniques may be necessary to derive a collective asset retirement obligation. This Subtopic does not preclude the use of estimates and computational shortcuts that are consistent with the fair value measurement objective when computing an aggregate asset retirement obligation for assets that are components of a larger group of assets.

This implementation guidance illustrates Section 410-20-15. If, for example, a governmental unit retains the right (an option) to decide whether to require a retirement activity, there is some uncertainty about whether those retirement activities will be required or waived. Regardless of the uncertainty attributable to the option, a legal obligation to stand ready to perform retirement activities still exists, and the governmental unit might require them to be performed. Although the timing and method of settlement of the retirement obligation may depend on future events that may or may not be within the control of the entity, a legal obligation to stand ready to perform retirement activities still exists. The entity should consider the uncertainty about the timing and method of settlement in the measurement of the liability, consistent with a fair value measurement objective, regardless of whether the event that will trigger the settlement is partially or wholly under the control of the entity.

This implementation guidance illustrates paragraph [410-20-30-1](https://asc.understandingaccounting.org/asc/410/20/#410-20-30-1). In estimating the fair value of a liability for an asset retirement obligation using an expected present value technique, an entity shall begin by estimating the expected cash flows that reflect, to the extent possible, a marketplace assessment of the cost and timing of performing the required retirement activities. Considerations in estimating those expected cash flows include developing and incorporating explicit assumptions, to the extent possible, about all of the following:

1.  a
    
    The costs that a third party would incur in performing the tasks necessary to retire the asset
    
2.  b
    
    Other amounts that a third party would include in determining the price of the transfer, including, for example, inflation, overhead, equipment charges, profit margin, and advances in technology
    
3.  c
    
    The extent to which the amount of a third party's costs or the timing of its costs would vary under different future scenarios and the relative probabilities of those scenarios
    
4.  d
    
    The price that a third party would demand and could expect to receive for bearing the uncertainties and unforeseeable circumstances inherent in the obligation, sometimes referred to as a market-risk premium.

It is expected that uncertainties about the amount and timing of future cash flows can be accommodated by using the expected present value technique and therefore will not prevent the determination of a reasonable estimate of fair value.

This implementation guidance illustrates paragraph [410-20-30-1](https://asc.understandingaccounting.org/asc/410/20/#410-20-30-1). An entity shall discount expected cash flows using an interest rate that equates to a risk-free interest rate adjusted for the effect of its credit standing (a credit-adjusted risk-free rate). In determining the adjustment for the effect of its credit standing, an entity should consider the effects of all terms, collateral, and existing guarantees on the fair value of the liability.

Adjustments for default risk can be reflected in either the discount rate or the expected cash flows. In most situations, an entity will know the adjustment required to the risk-free interest rate to reflect its credit standing. Consequently, it would be easier and less complex to reflect that adjustment in the discount rate.

An equivalent amount is added to the carrying amount of the liability. To calculate accretion expense, an entity shall multiply the beginning of the period liability balance by the credit-adjusted risk-free rate that existed when the liability was initially measured. The liability shall be adjusted for accretion prior to adjusting for revisions in estimated cash flows.

This implementation guidance illustrates paragraph [410-20-35-8](https://asc.understandingaccounting.org/asc/410/20/#410-20-35-8). Revisions to a previously recorded asset retirement obligation will result from changes in the assumptions used to estimate the expected cash flows required to settle the asset retirement obligation, including changes in estimated probabilities, amounts, and timing of the settlement of the asset retirement obligation, as well as changes in the legal requirements of an obligation. Any changes that result in upward revisions to the expected cash flows shall be treated as a new liability and discounted at the current rate. Any downward revisions to the expected cash flows will result in a reduction of the asset retirement obligation. For downward revisions, the amount of the liability to be removed from the existing accrual shall be discounted at the credit-adjusted risk-free rate that was used at the time the obligation to which the downward revision relates was originally recorded (or the historical weighted-average rate if the year\[s\] to which the downward revision applies cannot be determined).

This implementation guidance illustrates Section 410-20-15. There is no conceptual difference between interim property retirements and replacements and those retirements that occur in circumstances in which the retired asset is not replaced. Therefore, any asset retirement obligation associated with the retirement of or the retirement and replacement of a component part of a larger system qualifies for recognition provided that the obligation meets the definition of a liability. The cost of replacement components is excluded.

The Directive distinguishes between new and historical waste. All products put on the market on or before August 13, 2005, are deemed to be historical waste equipment for the purposes of the Directive. Example 4 (see paragraph [410-20-55-63](https://asc.understandingaccounting.org/asc/410/20/#410-20-55-63)) does not address the accounting for new waste because there should be little diversity in practice in the accounting for such waste. Costs relating to waste of new equipment are to be borne solely by the producers of the new equipment. This implementation guidance illustrates Section 410-20-15.

Under the Directive, the waste management obligation remains with the commercial user until the historical waste equipment is replaced, at which time the waste management obligation for that equipment may be transferred to the producer of the replacement equipment depending on the law adopted by the applicable EU-member country. If the commercial user does not replace the equipment, the obligation remains with that user until it disposes of the equipment. The Directive provides each EU-member country with the option to obligate commercial users to pay part or all of the costs associated with the historical waste even if the equipment is replaced. In this situation, the obligation would remain (partly or wholly) with the commercial user until the user disposes of the equipment.

If the asset is subsequently replaced, with the obligation being transferred to the producer of the replacement equipment, the commercial user should determine the portion of the total amount paid to the producer that relates to the replacement equipment (the new asset) and the portion that relates to the transfer of the asset retirement obligation. That determination should be based on the [fair value](https://asc.understandingaccounting.org/glossary/f/#fair-value "The price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date.") of the asset retirement obligation, without the sale of the new asset. The price paid by the commercial user would not include any costs associated with the transfer of the obligation in situations in which the law in the EU-member country obligates commercial users to pay all of the costs associated with the historical waste even if the equipment is replaced. In those situations, the commercial user would not derecognize the liability from its balance sheet upon replacement, but rather when the obligation is ultimately settled.

The new asset should be measured as the residual amount (the excess of the price paid over the fair value of the asset retirement obligation transferred). That amount should be used in determining the new asset's cost basis. The commercial user should derecognize the liability from its balance sheet and recognize a gain or loss based on the difference between the carrying amount of the liability at the date of the sale and the portion of the sales price that relates to the obligation. The producer of the new asset should recognize revenue for the total amount received reduced by the fair value of the obligation upon the transfer of the obligation from the commercial user (that is, on a net basis). The requirements for the producer to measure the revenue from the sale of the new asset as the residual amount and recognize revenue only for the sale of the new asset are applicable for those producers for which the recycling of electronic waste equipment is not a revenue-generating business activity. In situations in which the recycling of equipment is a revenue-generating business activity for the producer, that producer should apply the guidance in Topic 606 on [revenue](https://asc.understandingaccounting.org/glossary/r/#revenue "Inflows or other enhancements of assets of an entity or settlements of its liabilities (or a combination of both) from delivering or producing goods, rendering services, or other activities that constitute the entity's ongoing major or central operations.") from [contracts](https://asc.understandingaccounting.org/glossary/c/#contract "An agreement between two or more parties that creates enforceable rights and obligations.") with [customers](https://asc.understandingaccounting.org/glossary/c/#customer "A party that has contracted with an entity to obtain goods or services that are an output of the entity's ordinary activities in exchange for consideration.").

. After initial measurement, an entity is required to recognize period-to-period changes in an asset retirement obligation liability resulting from the passage of time (accretion expense) and revisions in cash flow estimates. To apply the subsequent measurement provisions of this Subtopic, an entity must identify undiscounted cash flows related to an asset retirement obligation liability irrespective of how the liability was initially measured. Therefore, if an entity obtains the initial fair value from a market price, it must impute undiscounted cash flows from that price.

This Example illustrates the subsequent measurement of a liability in situations where the initial liability is based on a market price. Assume that the liability is initially recognized at the end of period 0 when the market price is $300,000 and the entity's credit-adjusted risk-free rate is 8 percent. As required by this Subtopic, revisions in the timing or the amount of estimated cash flows are assumed to occur at the end of the period after accretion on the beginning balance of the liability is calculated. At the end of each period, the following procedure is used to impute cash flows from the end-of-period market price, compute the change in that price attributable to revisions in estimated cash flows, and calculate accretion expense:

1.  a
    
    The market price and the credit-adjusted risk-free interest rate are used to impute the undiscounted cash flows embedded in the market price.
    
2.  b
    
    The undiscounted cash flows from (a) are discounted at the initial credit-adjusted risk-free rate of 8 percent to arrive at the ending balance of the asset retirement obligation liability per the provisions of this Subtopic.
    
3.  c
    
    The beginning balance of the asset retirement obligation liability is multiplied by the initial credit-adjusted risk-free rate of 8 percent to arrive at the amount of accretion expense per the provisions of this Subtopic.
    
4.  d
    
    The difference between the undiscounted cash flows at the beginning of the period and the undiscounted cash flows at the end of the period represents the revision in cash flow estimates that occurred during the period. If that change is an upward revision to the undiscounted estimated cash flows, it is discounted at the current credit-adjusted risk-free rate. If that change is a downward revision, it is discounted at the historical weighted-average rate because it is not practicable to separately identify the period to which the downward revision relates.

The following Cases illustrate the recognition and measurement provisions of this Subtopic:

1.  a
    
    Initial measurement of a liability for an asset retirement obligation using an expected present value technique, subsequent measurement assuming that there are no changes in expected cash flows, and settlement of the asset retirement obligation liability at the end of its term (Case A)
    
2.  b
    
    Subsequent measurement of an asset retirement obligation liability after a change in expected cash flows (Case B)
    
3.  c
    
    Recognition and measurement of an asset retirement obligation liability that is incurred over more than one reporting period (Case C)
    
4.  d
    
    Accounting for asset retirement obligations that are conditional and that have a low likelihood of enforcement (Case D).

Cases A, B, C, and D incorporate simplified assumptions to provide guidance in implementing this Subtopic. For instance, Cases A and B relate to the asset retirement obligation associated with an offshore production platform that also would likely have individual wells and production facilities that would have separate asset retirement obligations. Those Cases also assume straight-line depreciation, even though, in practice, depreciation would likely be applied using a units-of-production method. Other simplifying assumptions are used throughout the Cases.

This Case depicts an entity that completes construction of and places into service an offshore oil platform on January 1, 2003. The entity is legally required to dismantle and remove the platform at the end of its useful life, which is estimated to be 10 years. Based on the requirements of this Subtopic, on January 1, 2003, the entity recognizes a liability for an asset retirement obligation and capitalizes an amount for an asset retirement cost. The entity estimates the initial fair value of the liability using an expected present value technique. The significant assumptions used in that estimate of fair value are as follows:

1.  a
    
    Labor costs are based on current marketplace wages required to hire contractors to dismantle and remove offshore oil platforms. The entity assigns probability assessments to a range of cash flow estimates as follows.
    
    -   ![](https://asc.understandingaccounting.org/asc-img/GUID-9B5EFC01-0264-4216-A87C-C41F345F4F70-low.gif)
        
        Cash Flow Estimate Probability Assessment Expected Cash Flows " $100,000 " 25% " $25,000 " " 125,000 " 50 " 62,500 " " 175,000 " 25 " 43,750 " " $131,250 "
        
2.  b
    
    The entity estimates allocated overhead and equipment charges using the rate it applies to labor costs for transfer pricing (80 percent). The entity has no reason to believe that its overhead rate differs from those used by contractors in the industry.
    
3.  c
    
    A contractor typically adds a markup on labor and allocated internal costs to provide a profit margin on the job. The rate used (20 percent) represents the entity's understanding of the profit that contractors in the industry generally earn to dismantle and remove offshore oil platforms.
    
4.  d
    
    A contractor would typically demand and receive a premium (market risk premium) for bearing the uncertainty and unforeseeable circumstances inherent in locking in today's price for a project that will not occur for 10 years. The entity estimates the amount of that premium to be 5 percent of the expected cash flows adjusted for inflation.
    
5.  e
    
    The risk-free rate of interest on January 1, 2003, is 5 percent. The entity adjusts that rate by 3.5 percent to reflect the effect of its credit standing. Therefore, the credit-adjusted risk-free rate used to compute expected present value is 8.5 percent.
    
6.  f
    
    The entity assumes a rate of inflation of 4 percent over the 10-year period.

On December 31, 2012, the entity settles its asset retirement obligation by using its internal workforce at a cost of $351,000. Assuming no changes during the 10-year period in the expected cash flows used to estimate the obligation, the entity would recognize a gain of $89,619 on settlement of the obligation. The entity would account for the asset retirement obligation as follows.

On December 31, 2004, the entity revises its estimate of labor costs to reflect an increase of 10 percent in the marketplace. In addition, it revises the probability assessments related to those labor costs. The change in labor costs results in an upward revision to the expected cash flows; consequently, the incremental expected cash flows are discounted at the current credit-adjusted risk-free rate of 8 percent. All other assumptions remain unchanged. The revised estimate of expected cash flows for labor costs is as follows.

On December 31, 2005, the entity increases by 10 percent its estimate of expected cash flows that were used to measure those portions of the liability recognized on December 31, 2003, and December 31, 2004, which results in an upward revision to the expected cash flows. Accordingly, the incremental expected cash flows of $2,415 \[$2,300 (10 percent of $23,000) plus $115 (10 percent of $1,150)\] are discounted at the then-current credit-adjusted risk-free rate of 9.2 percent and recorded as a liability on December 31, 2005. The entity would account for the asset retirement obligation as follows.

This Case illustrates a timber lease in which the [lessor](https://asc.understandingaccounting.org/glossary/l/#lessor "An entity that enters into a contract to provide the right to use an underlying asset for a period of time in exchange for consideration.") has an option to require the [lessee](https://asc.understandingaccounting.org/glossary/l/#lessee "An entity that enters into a contract to obtain the right to use an underlying asset for a period of time in exchange for consideration.") to settle an asset retirement obligation. Assume an entity enters into a five-year [lease](https://asc.understandingaccounting.org/glossary/l/#lease "A contract, or part of a contract, that conveys the right to control the use of identified property, plant, or equipment (an identified asset) for a period of time in exchange for consideration.") that grants it the right to harvest timber on a tract of land and that agreement grants the lessor an option to require that the lessee reforest the underlying land at the end of the [lease term](https://asc.understandingaccounting.org/glossary/l/#lease-term "The noncancellable period for which a lessee has the right to use an underlying asset, together with all of the following: Periods covered by an option to extend the lease if the lessee is reasonably certain to exercise that option Periods covered by an option to terminate the lease if the lessee is reasonably certain not to exercise that option Periods covered by an option to extend (or not to terminate) the lease in which exercise of the option is controlled by the lessor."). Based on past history, the lessee believes that the likelihood that the lessor will exercise that option is low. Rather, at the end of the lease, the lessor will likely accept the land without requiring reforestation. The lessee estimates that there is only a 10 percent probability that the lessor will elect to enforce reforestation. Paragraph [842-10-15-1](https://asc.understandingaccounting.org/asc/842/10/#842-10-15-1) explains that Topic 842 does not apply to leases of biological assets, including timber.

At the end of the first year, 20 percent of the timber has been harvested. The lessee estimates that the possible cash flows associated with performing reforestation activities in 4 years for the portion of the land that has been harvested will be $300,000. When estimating the fair value of the asset retirement obligation liability to be recorded (using an expected present value technique), the lessee incorporates the probability that the restoration provisions will not be enforced.

During the term of the lease, the lessee should reassess the likelihood that the lessor will require reforestation. For example, if the lessee subsequently determines that the likelihood of the lessor electing the reforestation option has increased, that change will result in a change in the expected cash flows and be accounted for as illustrated in Case B.

This Example includes four Cases that illustrate when an entity would be required to recognize the fair value of an asset retirement obligation. The Cases do not provide specific guidance for determining when an entity has sufficient information to reasonably estimate the fair value of the asset retirement obligation. The determination as to when an entity has sufficient information to reasonably estimate the fair value of an asset retirement obligation should be based on the guidance in paragraphs

[410-20-25-8 through 25-11](https://asc.understandingaccounting.org/asc/410/20/#410-20-25-8)

. The Cases illustrate the initial recognition of a [conditional asset retirement obligation](https://asc.understandingaccounting.org/glossary/c/#conditional-asset-retirement-obligation "A legal obligation to perform an asset retirement activity in which the timing and (or) method of settlement are conditional on a future event that may or may not be within the control of the entity.") based on the facts presented. Any differences in facts from those presented in the Cases may result in different conclusions.

Assume a telecommunications entity owns and operates a communication network that uses wood poles that are treated with certain chemicals. There is no legal requirement to remove the poles from the ground. However, the owner may replace the poles periodically for a number of operational reasons. Once the poles are removed from the ground, they may be disposed of, sold, or reused as part of other activities. There is existing legislation that requires special disposal procedures for the poles in the particular state in which the entity operates.

At the date of purchase of the treated poles, the entity has the information to estimate a range of potential settlement dates, the potential methods of settlement, and the probabilities associated with the potential settlement dates and methods based on established industry practice. Therefore, at the date of purchase, the entity is able to estimate the fair value of the liability for the required disposal procedures using an expected present value technique.

Although the timing of the performance of the asset retirement activity is conditional on removing the poles from the ground and disposing of them, existing legislation creates a duty or responsibility for the entity to dispose of the poles in accordance with special procedures, and the obligating event occurs when the entity purchases the treated poles. Although the entity may decide not to remove the poles from the ground or may decide to reuse the poles and thereby defer settlement of the obligation, the ability to defer settlement does not relieve the entity of the obligation. The poles will eventually need to be disposed of using special procedures, because the poles will not last forever. Additionally, the ability of the entity to sell the poles prior to disposal does not relieve the entity of its present duty or responsibility to settle the obligation. The sale of the poles transfers the obligation to another entity. The assumption of the obligation by the buyer affects the exchange price. The bargaining of the exchange price reflects the buyer's and seller's individual estimates of the timing and (or) amount of the cost to extinguish the obligation.

The asset retirement obligation should be recognized when the entity purchases the poles because the entity has sufficient information to estimate the fair value of the asset retirement obligation. Because the legal requirement relates only to the disposal of the treated poles, the cost to remove the poles is not included in the asset retirement obligation. However, if there was a legal requirement to remove the treated poles, the cost of removal would be included.

Assume an entity recently purchased several kilns lined with a special type of brick. As of the date of purchase, the kilns had not yet been used in any smelting processes. The kilns have a long useful life, but the bricks are replaced periodically. Because the bricks become contaminated with hazardous chemicals while the kiln is operated, a state law requires that when the bricks are removed, they must be disposed of at a special hazardous waste site. The entity has the information to estimate a range of potential settlement dates, the method of settlement, and the probabilities associated with the potential settlement dates based on its past practice of replacing the bricks to maintain the efficient operation of the kiln.

Although performance of the asset retirement activity is conditional on removing the bricks from the kiln, existing legislation creates a duty or responsibility for the entity to dispose of the bricks at a special hazardous waste site, and the obligating event occurs when the entity contaminates the bricks. As of the purchase date, the kilns have not yet been used in any smelting processes, and the bricks have not yet been contaminated. Therefore, at the date of purchase, no obligation exists because the bricks have not been contaminated and could be disposed of without performing any special disposal activities.

The fair value of the asset retirement obligation should be recognized once the kilns have been placed into operation and the bricks are contaminated. Although the entity may decide not to remove the bricks from the kiln and thereby defer settlement of the obligation, the ability to defer settlement does not relieve the entity of the obligation. The contaminated bricks will eventually need to be removed and disposed of at a special hazardous waste site, because a kiln will not last forever. Therefore, the obligation to perform the asset retirement activity is unconditional even though uncertainty exists about the timing of settlement. An asset retirement obligation should be recognized once the kilns have been placed into operation and the bricks are contaminated because the entity has sufficient information to estimate the fair value of the asset retirement obligation. The asset retirement obligation is the requirement to dispose of the contaminated bricks at a special hazardous waste site. The cost to remove the bricks is not part of the obligation and should be accounted for as a maintenance or replacement activity.

Assume an entity acquires a factory that contains asbestos. After the acquisition date, regulations are put in place that require the entity to handle and dispose of this type of asbestos in a special manner if the factory undergoes major renovations or is demolished. Otherwise, the entity is not required to remove the asbestos from the factory. The entity has several options to retire the factory in the future including demolishing, selling, or abandoning it. The entity believes it does not have sufficient information to estimate the fair value of the asset retirement obligation because the settlement date or the range of potential settlement dates has not been specified by others and information is not available to apply an expected present value technique. For example, there are no plans or expectation of plans to undertake a major renovation that would require removal of the asbestos or demolition of the factory. The factory is expected to be maintained by repairs and maintenance activities that would not involve the removal of the asbestos. Also, the need for major renovations caused by technology changes, operational changes, or other factors has not been identified.

Although the timing of the performance of the asset retirement activity is conditional on the factory undergoing major renovations or being demolished, existing regulations create a duty or responsibility for the entity to remove and dispose of asbestos in a special manner, and the obligating event occurs when the regulations are put in place. Therefore, an asset retirement obligation should be recognized when regulations are put in place if the entity can reasonably estimate the fair value of the liability. In this Case, the entity believes that there is an indeterminate settlement date for the asset retirement obligation because the range of time over which the entity may settle the obligation is unknown or cannot be estimated. Therefore, the entity cannot reasonably estimate the fair value of the liability. Accordingly, the entity would not recognize a liability for the asset retirement obligation when regulations are put in place, but it should disclose a description of the obligation, the fact that a liability has not been recognized because the fair value cannot be reasonably estimated, and the reasons why fair value cannot be reasonably estimated. The entity would recognize a liability in the period in which sufficient information is available to reasonably estimate its fair value.

Assume an entity acquires a factory that contains asbestos. At the acquisition date, regulations are in place that require the entity to handle and dispose of this type of asbestos in a special manner if the factory undergoes major renovations or is demolished. Otherwise, the entity is not required to remove the asbestos from the factory. The entity has several options to retire the factory in the future including demolishing, selling, or abandoning it. At the acquisition date, it is not evident that the fair value of the obligation is embodied in the acquisition price of the factory because both the seller and the buyer of the factory believed the obligation had an indeterminate settlement date, an active market does not exist for the transfer of the obligation, and sufficient information does not exist to apply an expected present value technique. Ten years after the acquisition date, the entity obtains additional information based on changes in demand for the products manufactured at that factory. At that time, the entity has the information to estimate a range of potential settlement dates, the potential methods of settlement, and the probabilities associated with the potential settlement dates and potential methods of settlement. Therefore, at that time the entity is able to estimate the fair value of the liability for the special handling of the asbestos using an expected present value technique.

Although timing of the performance of the asset retirement activity is conditional on the factory undergoing major renovations or being demolished, existing regulations create a duty or responsibility for the entity to remove and dispose of asbestos in a special manner, and the obligating event occurs when the entity acquires the factory. In this Case, regulations are in place at the date of acquisition that require the entity to handle and dispose of the asbestos in a special manner. Therefore, the obligating event is the acquisition of the factory. If regulations were enacted after the date of acquisition, the obligating event would be the enactment of the regulations (see Case C).

Although the entity may decide to abandon the factory and thereby defer settlement of the obligation for the foreseeable future, the ability to defer settlement does not relieve the entity of the obligation. The asbestos will eventually need to be removed and disposed of in a special manner, because no building will last forever. Additionally, the ability of the entity to sell the factory does not relieve the entity of its present duty or responsibility to settle the obligation. The sale of the asset would transfer the obligation to another entity and that transfer would affect the selling price. Therefore, the obligation to perform the asset retirement activity is unconditional even though uncertainty exists about the timing and method of settlement.

In this Case, an asset retirement obligation is not recognized when the entity acquires the factory because the entity does not have sufficient information to estimate the fair value of the obligation. The entity would disclose a description of the obligation, the fact that a liability has not been recognized because the fair value cannot be reasonably estimated, and the reasons why fair value cannot be reasonably estimated. An asset retirement obligation would be recognized by this entity 10 years after the acquisition date because that is when the entity has sufficient information to estimate the fair value of the asset retirement obligation.

Assume an entity (a commercial user) is currently using electronic equipment that must be disposed of in accordance with the requirements of EU Directive 2002/96/EC. The EU-member country has not yet adopted the legislation. The entity has the ability either to replace the equipment or to dispose of the equipment without replacing it. In the EU-member country in which the entity operates, the producer of the replacement equipment will be wholly responsible for disposal costs if and when the equipment is replaced. The recycling of electronic waste equipment is not a revenue-generating business activity of the producer.

Upon the adoption of the legislation, the entity should recognize a liability for the fair value of the asset retirement obligation. Upon initial recognition of a liability, the entity should capitalize an asset retirement cost by increasing the carrying amount of the related asset by the same amount as the liability. The accounting subsequent to the initial recognition of the asset and liability should be consistent with the guidance in paragraphs

The waste management obligation remains with the commercial user until the historical waste equipment is replaced or is disposed of by the commercial user itself. Assuming the equipment is replaced, the entity should determine the portion of the purchase price that relates to the cost of the replacement asset and the portion that relates to the assumption of the obligation by the producer. That determination should be based on the fair value of the obligation, without the sale of the new asset. The entity should recognize a gain or loss based on the difference between the carrying amount of the liability at the date of the sale and the portion of the sales price that relates to the obligation. The producer should recognize revenue for the total amount received, reduced by the fair value of the obligation, and recognize a liability for the fair value of the obligation upon transfer of the obligation from the commercial user. Assuming the equipment is disposed of by the entity rather than replaced, the entity should recognize a gain or loss based on the difference between the carrying amount of the liability at the date of the disposal and the actual cost of disposal.

## ASC 410-30: Asset Retirement and Environmental Obligations — Environmental Obligations

### Machine-generated study aids

```json
{
  "summary": "ASC 410-30 governs accounting for environmental remediation liabilities — obligations to clean up pollution arising from past acts under Superfund (CERCLA), RCRA corrective-action provisions, or analogous state/non-U.S. laws. Applied site by site, it uses the loss contingency model of ASC 450-20: accrue when it is probable a liability has been incurred (litigation/claim asserted or probably will be, and an unfavorable outcome probable) and the amount (or a minimum in a range) is reasonably estimable, measured as the entity's allocable share of the joint and several liability plus amounts other PRPs won't pay. Remediation costs are generally expensed as a component of operating income, with narrow capitalization exceptions and separate recognition of probable third-party recoveries as assets.",
  "key_points": [
    "Accrual follows 450-20-25-2: probable that a liability has been incurred and reasonably estimable; in the remediation context probability has two elements — litigation/claim/assessment commenced or probable commencement, and probable unfavorable outcome (410-30-25-4), with a presumption of unfavorable outcome if the entity is associated with the site (410-30-25-6).",
    "Inability to estimate the total liability does not defer recognition: components that can be reasonably estimated serve as a surrogate for the minimum of the overall range, and the best estimate (or minimum of a range) must be recognized and refined as events occur (410-30-25-10 through 25-13).",
    "Recognition benchmarks — PRP identification, receipt of a unilateral administrative order, participation in the remedial investigation-feasibility study, completion of the feasibility study, record of decision, and remedial design through operation and maintenance — must be evaluated, but may not be used to delay recognition beyond the point the 450-20 criteria are met (410-30-25-14 through 25-15).",
    "Measurement is the entity's estimated allocable share of the joint and several liability plus its share of amounts that will not be paid by other PRPs or the government, with a rebuttable presumption that costs are allocated only among participating PRPs (410-30-30-1, 30-4, 30-7, 30-8).",
    "Included costs are incremental direct costs of the remediation effort and compensation/benefits of employees devoting significant time to it, based on enacted laws and adopted regulations, estimated at the cost when the work is expected to be performed; discounting is permitted only if the amount and timing of payments are fixed or reliably determinable (410-30-30-10, 30-15, 30-17, 410-30-35-12).",
    "Remediation costs are generally charged to expense and reported in operating income, with recovery credits in the same line item; capitalization is allowed only if costs are recoverable and they improve the property versus its original condition, prevent future contamination, or ready property held for sale (410-30-25-16, 25-18, 410-30-45-4).",
    "A recovery asset is recognized only when realization of the claim is probable, measured independently of the liability, with a rebuttable presumption that realization is not probable if the claim is in litigation; disclosure must state whether the accrual is discounted, and if so the undiscounted amount and discount rate (410-30-35-8, 35-9, 410-30-50-4, 50-7)."

The Environmental Protection Agency has the authority to require potentially responsible parties, through administrative and legal actions, to remediate such sites. At early stages of the remediation process, the list of potentially responsible parties may be limited to a handful of entities that either were significant contributors of waste to the site or were easy to identify, for example, because of their proximity to the site or because of labeled material found at the site. As further investigation of the site occurs and as remediation activities take place, additional potentially responsible parties may be identified. Once identified, the additional potentially responsible parties would be reclassified from this category to either the participating potentially responsible party or recalcitrant potentially responsible party category. The total number of parties in this category and their aggregate allocable share of the remediation liability varies by site and cannot be reliably determined before the specific identification of individual potentially responsible parties. For example, some ultimately may be dropped from the potentially responsible party list because no substantive evidence is found to link them to the site. For others, substantive evidence eventually may be found that points to their liability. The presentation of that evidence to the entity would result in a reclassification of the party from this category of potentially responsible parties (sometimes referred to as hiding in the weeds) to either the participating potentially responsible party or recalcitrant potentially responsible party category."><span>Potentially Responsible Party</span></a></td><td class="entry">Added</td><td class="entry"><a href="https://asc.understandingaccounting.org/updates/asu-2014-06/" class="xref">Accounting Standards Update No. 2014-06</a></td><td class="entry">03/14/2014</td></tr><tr><td class="entry"><a href="https://asc.understandingaccounting.org/glossary/r/#recalcitrant-potentially-responsible-party" class="term" title="A party whose liability with respect to a Superfund site is substantiated by evidence, but that refuses to acknowledge potential involvement with respect to the site.

Although this Section focuses on both state and federal U. S. laws and regulations, environmental considerations are also important for foreign operations. Environmental laws and regulations in many countries are similar to U. S. laws. The legal and regulatory climates in other countries are evolving. Regardless of whether the host countries' environmental laws are as stringent as those in the United States, entities can often be held liable for environmental damages under a variety of nonenvironmental statutes and broad legal theories.

The first kind of environmental law, environmental remediation liability laws, includes individual statutes as well as response provisions in other statutes. The most important of these are the Comprehensive Environmental Response, Compensation, and Liability Act of 1980, as amended by the Superfund Amendments and the Reauthorization Act of 1986, which together are referred to as Superfund, and the [corrective action](https://asc.understandingaccounting.org/glossary/c/#corrective-action "Related to the Resource Conservation and Recovery Act of 1976: action to remedy releases from hazardous waste management units, or any other sources of releases at or from a treatment, storage, or disposal facility.") provisions of the Resource Conservation and Recovery Act of 1976. Under Superfund's current broad liability provisions, the U.S. Environmental Protection Agency may order liable parties to remediate sites or use Superfund money to remediate them and then seek to recover its costs and additional damages. Similarly, under the corrective action provisions of the Resource Conservation and Recovery Act of 1976, the Environmental Protection Agency may order "facilities that treat, store, or dispose of hazardous waste" to clean up releases of [hazardous waste constituents](https://asc.understandingaccounting.org/glossary/h/#hazardous-waste-constituent "A constituent that caused the waste to be listed as a hazardous waste under the Resource Conservation and Recovery Act of 1976 40 CFR Part 261 Subpart D.") associated with past or ongoing practices.

Congress enacted the Comprehensive Environmental Response, Compensation, and Liability Act of 1980 in 1980 to facilitate the remediation of abandoned waste sites. The Comprehensive Environmental Response, Compensation, and Liability Act established a program to identify sites where hazardous substances have been or might be released into the environment; to ensure that they are remediated by responsible parties or the government; to compensate the United States, states, municipalities, and tribes for damages to [natural resources](https://asc.understandingaccounting.org/glossary/n/#natural-resources "Under the Comprehensive Environmental Response, Compensation, and Liability Act of 1980, natural resources are defined as land, fish, wildlife, biota, air, water, groundwater, drinking water supplies, and other such resources belonging to, managed or held in trust by, or otherwise controlled by the United States, state or local governments, foreign governments, or Indian tribes."); and to create a procedure for claims against responsible parties by parties who have cleaned up sites or spent money to restore natural resources.

The Resource Conservation and Recovery Act provides comprehensive federal regulation of [hazardous wastes](https://asc.understandingaccounting.org/glossary/h/#hazardous-waste "Related to Resource Conservation and Recovery Act of 1976: a waste, or combination of wastes, that because of its quantity, concentration, toxicity, corrosiveness, mutagenicity or inflammability, or physical, chemical, or infectious characteristics may cause, or significantly contribute to, an increase in mortality or an increase in serious irreversible, or incapacitating reversible illness or pose a substantial present or potential hazard to human health or the environment when improperly treated, stored, transported, or disposed of, or otherwise managed. Technically, those wastes that are regulated under the Resource Conservation and Recovery Act of 1976 40 CFR Part 261 are considered to be hazardous wastes.") from point of generation to final [disposal](https://asc.understandingaccounting.org/glossary/d/#disposal "Related to the Comprehensive Environmental Response, Compensation, and Liability Act of 1980 and the Resource Conservation and Recovery Act of 1976: under the Resource Conservation and Recovery Act of 1976, the discharge, deposit, injection, dumping, spilling, leaking, or placing of any solid waste or hazardous waste into or on any land or water so that such solid waste or hazardous waste or any constituent thereof may enter the environment or be emitted into the air or discharged into any waters, including groundwaters. Similarly under the Comprehensive Environmental Response, Compensation, and Liability Act of 1980 with regard to hazardous substances."). All generators of hazardous waste, transporters of hazardous waste, and owners and operators of hazardous waste treatment, storage, or disposal facilities must comply with the applicable requirements of the statute. Many states have also enacted laws that are similar to the federal statutes. Furthermore, under certain federal statutes, such as the Resource Conservation and Recovery Act of 1976, states are allowed to promulgate regulations to implement federal programs as long as the state law is at least as stringent as the federal law. In most such cases, states are free to enact more stringent provisions.

Environmental laws of the second kind are intended to control or prevent pollution and are directed at identifying or regulating pollution sources or reducing emissions or discharges of pollutants. There are many statutes that regulate sources of pollution, including the pollution control provisions of the Resource Conservation and Recovery Act of 1976 (solid and hazardous wastes), the Clean Water Act (discharge of pollutants into the waters of the United States and to publicly owned treatment works), and the Clean Air Act (emission of pollutants into the atmosphere). Other examples are the Emergency Planning and Community Right-to-Know Act and the Pollution Prevention Act of 1990.

The pollution control provisions in Chapter 3 of the Resource Conservation and Recovery Act of 1976 provide for cradle-to-grave management standards for hazardous wastes. Section 7003 of the Resource Conservation and Recovery Act of 1976 also authorizes the Environmental Protection Agency to conduct [removal actions](https://asc.understandingaccounting.org/glossary/r/#removal-action "Under the Comprehensive Environmental Response, Compensation, and Liability Act of 1980, generally short-term actions taken to respond promptly to an urgent need. The cleanup or removal of released hazardous substances from the environment; actions in response to the threat of release; actions that may be necessary to monitor, assess, and evaluate the release or threat; disposal of removed material; or other actions needed to prevent, minimize, or mitigate damage to public health or welfare or to the environment. Removal also includes, without being limited to, security fencing or other measures to limit access; provision of alternative water supplies; temporary evacuation and housing of threatened individuals not otherwise provided for; and any emergency assistance provided under the Disaster Relief Act."), seek affirmative injunctive relief, and maintain cost-recovery actions where an imminent and substantial endangerment to the public health or welfare or to the environment is determined to exist. Much like under Superfund, one who has contributed to the disposal of waste that is causing an imminent and substantial endangerment can be required to perform or pay for associated remediation under section 7003. The Resource Conservation and Recovery Act of 1976 also requires the Environmental Protection Agency to regulate underground storage tanks. Most states have enacted their own underground storage tank regulations as well.

The Clean Air Act provides comprehensive federal regulation of all sources of air pollution. Amendments to the Clean Air Act in the 1990s are designed to address issues such as acid rain, urban air pollution, toxic air pollutants, and ozone-depleting chemicals. The major provisions of the Clean Air Act amendments require emissions reduction in the electric utility industry, operating permits for existing facilities, an expansion of the air toxics program to regulate a large number of toxic air pollutants, and new source categories (including smaller sources, such as dry cleaners).

The Clean Water Act provides comprehensive federal regulation of all sources of water pollution. The act authorizes cleanup, injunctive, and cost-recovery actions where an imminent hazard is caused by pollution. It also prohibits the discharge of oil and other hazardous substances to the navigable waters of the United States, imposes a criminal penalty for failure to notify the appropriate entity of such discharges, and provides for citizen suits. Most states have assumed enforcement of the Act within their borders through state regulations that correspond to the federal regulations related to the control or prevention of pollution of water.

The Emergency Planning and Community Right-to-Know Act requires facilities that have certain quantities of extremely hazardous substances to notify their state emergency response commission that they are subject to the emergency planning requirements of the Superfund Amendments and Reauthorization Act of 1986. They must also report releases to the local emergency planning committee. In addition, facilities that store chemicals over specified threshold amounts must submit material safety data sheets, or their equivalent, to the appropriate local emergency planning committee, the state emergency response commission, and the fire department with jurisdiction over the facility.

The Toxic Substances Control Act regulates the manufacture, processing, and distribution in commerce of chemical substances and mixtures capable of adversely affecting health or the environment. The Toxic Substances Control Act may require testing and may impose use restrictions, along with requirements for the reporting and retention of information on the risks of Toxic Substances Control Act- regulated substances. Regulations promulgated under the Toxic Substances Control Act also govern the manufacturing, processing, and distribution in commerce of polychlorinated biphenyls and asbestos.

Superfund places liability on the following four distinct classes of responsible parties:

1.  a
    
    Current owners or operators of sites at which hazardous substances have been disposed of or abandoned
    
2.  b
    
    Previous owners or operators of sites at the time of disposal of hazardous substances
    
3.  c
    
    Parties that "arranged for disposal" of hazardous substances found at the sites
    
4.  d
    
    Parties that transported hazardous substances to a site, having selected the site for treatment or disposal.

This liability is imposed regardless of whether a party was negligent, whether the site was in compliance with environmental laws at the time of the disposal, or whether the party participated in or benefited from the deposit of the [hazardous substance](https://asc.understandingaccounting.org/glossary/h/#hazardous-substance "Related to Superfund: the definition of hazardous substance in the Comprehensive Environmental Response, Compensation, and Liability Act of 1980 is broader than the definition of hazardous wastes under the Resource Conservation and Recovery Act of 1976. Under the Comprehensive Environmental Response, Compensation, and Liability Act of 1980, a hazardous substance is any element, compound, mixture, solution, or substance that, when released to the environment, may present substantial danger to the public health or welfare or to the environment. It also includes the following: Specifically designated substances Toxic pollutants under the Federal Water Pollution Control Act Hazardous wastes having the characteristics identified under or listed pursuant to the Resource Conservation and Recovery Act of 1976 (excluding any waste suspended from regulation under the Solid Waste Disposal Act by Congress) Hazardous air pollutants under the Clean Air Act Any imminently hazardous chemical substance or mixture for which the government has taken action under section 7 of the Toxic Substances Control Act. Petroleum (including crude oil not otherwise specifically listed or designated as a hazardous substance under any of those laws), natural gas, natural gas liquids, liquefied natural gas, or synthetic gas useable for fuel (or mixtures of natural gas and such synthetic gas) are excluded.").

The courts have interpreted the Comprehensive Environmental Response, Compensation, and Liability Act of 1980 to impose [strict liability](https://asc.understandingaccounting.org/glossary/s/#strict-liability "Liability imposed without regard to the liable party's fault."). Thus, a waste generator that disposed of its waste at approved facilities, in accordance with all then-current requirements, having exercised "due care," would nevertheless be liable. Further, a waste generator that is responsible for a small percentage of the total amount of waste at a site may be held liable for the entire cost of remediating the site.

Also noteworthy is that wastes need not be hazardous wastes for there to be environmental remediation liability. If the waste generator "arranged for disposal" of wastes containing hazardous substances (at any concentration level and regardless of whether the substances were defined as, or known to be, hazardous at the time of disposal), and a "release" of hazardous substances has or could occur, the waste generator could be subject to environmental remediation liability.

Hazardous substance is a much broader term than hazardous waste. It includes any substance identified by the Environmental Protection Agency by regulation, pursuant to a number of federal statutes. Covered, for example, are substances considered to be toxic pollutants under the Clean Water Act or hazardous air pollutants under the Clean Air Act. The various lists of hazardous substances identified by the Environmental Protection Agency contain more than one thousand chemicals and chemical compounds.

Through Environmental Protection Agency initiated legal action, liability under the Comprehensive Environmental Response, Compensation, and Liability Act of 1980 may be [joint and several](https://asc.understandingaccounting.org/glossary/j/#joint-and-several-liability "Where liability is joint and several, any party deemed liable is potentially responsible for all of the associated costs. This scheme of liability means that any responsible party can potentially be liable for the entire cost of remediating a site, notwithstanding that the party is responsible for only a small amount of the total hazardous substances or waste at the site and did nothing improper."). If a potentially responsible party can prove, however, that the harm is divisible and there is a reasonable basis for apportionment of costs, the potentially responsible party may ultimately be responsible only for its portion of the costs.

In order to mitigate the potentially harsh effects of the strict, joint and several, and retroactive liability scheme, however, Superfund does permit responsible parties to sue other responsible parties to make them contribute to the cost of the remediation or to recover money spent on remediation.

Costs to a potentially responsible party may include cleanup costs (containment, removal, [remedial action](https://asc.understandingaccounting.org/glossary/r/#remedial-action "Related to Superfund: generally long-term actions taken to do any of the following: Investigate, alleviate, or eliminate the effects of a release of a hazardous substance into the environment Investigate, alleviate, or eliminate a threat of the release of an existing hazardous substance that could potentially harm human health or the environment Restore natural resources. Also refers to corrective action under the Resource Conservation and Recovery Act of 1976.")), enforcement costs (for example, legal), government oversight costs, and natural resource damages. Though the Comprehensive Environmental Response, Compensation, and Liability Act of 1980 does not provide for personal injury or property damage suits, suits for injury to health or property (referred to as toxic torts) may also be brought by third parties under various legal theories. There is a growing specter of liability for natural resource damages under the Superfund laws. The Comprehensive Environmental Response, Compensation, and Liability Act of 1980 authorizes the recovery of damages for injury to, destruction of, or loss of natural resources, including reasonable costs for assessing such injury resulting from a release of a hazardous substance. Natural resource damage claims include actual restoration costs and lost use values and may in the future include nonuse values, such as the intrinsic public value of protecting or restoring resources that may not be used but are valuable for their mere existence.

Additional costs can include a remedial investigation and a feasibility study that together generally take a minimum of two years to complete and, depending on factors such as the types of hazardous substances, soil formations, and number of parties involved, may take more than five years. The Environmental Protection Agency oversees the progress of the remedial investigation and feasibility study, and completion is sometimes performed in stages. After Superfund site remedial action is completed, activities must be conducted at the site to ensure that the remedy is effective and operating properly. For example, after a system to pump and treat groundwater is constructed (remedial action), the system must be operated and maintained. In addition, the Environmental Protection Agency may require postremediation monitoring. These operation and maintenance activities may continue for 30 years or longer.

An entity's environmental remediation obligation that results in a liability generally does not become determinable as a distinct event, nor is the amount of the liability generally fixed and determinable at a specific point in time. Rather, the existence of a liability for environmental remediation costs becomes determinable and the amount of the liability becomes estimable over a continuum of events and activities that help to frame, define, and verify the liability.

1.  a
    
    Litigation has commenced or a claim or an assessment has been asserted, or, based on available information, commencement of litigation or assertion of a claim or an assessment is probable. In other words, it has been asserted (or it is probable that it will be asserted) that the entity is responsible for participating in a remediation process because of a past event.
    
2.  b
    
    Based on available information, it is probable that the outcome of such litigation, claim, or assessment will be unfavorable. In other words, an entity will be held responsible for participating in a remediation process because of the past event.

Estimating environmental remediation liabilities involves an array of issues at any point in time. In the early stages of the process, cost estimates can be difficult to derive because of uncertainties about a variety of factors. For this reason, estimates developed in the early stages of remediation can vary significantly; in many cases, early estimates later require significant revision. The following are some of the factors that are integral to developing cost estimates:

1.  a
    
    The extent and types of hazardous substances at a site
    
2.  b
    
    The range of technologies that can be used for remediation
    
3.  c
    
    Evolving standards of what constitutes acceptable remediation
    
4.  d
    
    The number and financial condition of other potentially responsible parties and the extent of their responsibility for the remediation (that is, the extent and types of hazardous substances they contributed to the site).

An estimate of the range of an environmental remediation liability typically is derived by combining estimates of various components of the liability (such as the costs of performing particular tasks, or amounts allocable to other potentially responsible parties but that will not be paid by those other potentially responsible parties), which are themselves likely to be ranges. For some of those component ranges, there may be amounts that appear to be better estimates than any other amount within the range; for other component ranges, there may be no such best estimates. Accordingly, the overall liability that is recorded may be based on amounts representing the lower end of a range of costs for some components of the liability and best estimates within ranges of costs of other components of the liability.

At the early stages of the remediation process, particular components of the overall liability may not be reasonably estimable. This fact should not preclude the recognition of a liability. Rather, the components of the liability that can be reasonably estimated should be viewed as a surrogate for the minimum in the range of the overall liability.

For example, a sole potentially responsible party that has confirmed that it sent waste to a Superfund site and agrees to perform a remedial investigation and feasibility study may know that it will incur costs related to the [remedial investigation-feasibility study](https://asc.understandingaccounting.org/glossary/r/#remedial-investigation-feasibility-study "Extensive technical studies conducted by the government or by the potentially responsible parties to investigate the scope of site impacts and determine the remedial alternatives that, consistent with the National Contingency Plan, may be implemented at a Superfund site. Government-funded remedial investigation-feasibility studies do not recommend a specific alternative for implementation. Remedial investigation-feasibility studies conducted by potentially responsible parties usually do recommend and technically support a remedial alternative. A remedial investigation-feasibility study may include a variety of on- and off-site activities, such as monitoring, sampling, and analysis."). The potentially responsible party, although aware that the total costs associated with the site will be greater than the cost of the remedial investigation-feasibility study, may be unable to reasonably estimate the overall liability because of existing uncertainties, for example, regarding the kinds and quantities of hazardous substances present at the site and the technologies available to remediate the site. This lack of ability to quantify the total costs of the remediation effort, however, shall not preclude recognition of the estimated cost of the remedial investigation-feasibility study. In this circumstance, a liability for the best estimate (or, if no best estimate is available, the minimum amount in the range) of the cost of the remedial investigation-feasibility study and for any other component remediation costs that can be reasonably estimated shall be recognized in the entity's financial statements.

The following are recognition benchmarks for a Superfund remediation liability; analogous stages of the Resource Conservation and Recovery Act corrective-action process are also indicated. At a minimum, the estimate of a Superfund (or Resource Conservation and Recovery Act) remediation liability should be evaluated as each of these benchmarks occurs.

1.  a
    
    Identification and verification of an entity as a potentially responsible party. The Resource Conservation and Recovery Act analogue is subjection to facility permit requirements. Receipt of notification or otherwise becoming aware that an entity may be a potentially responsible party compels the entity to action. The entity must examine its records to determine whether it is associated with the site. If, based on a review and evaluation of its records and all other available information, the entity determines that it is associated with the site, it is probable that a liability has been incurred. If all or a portion of the liability is reasonably estimable, the liability shall be recognized. In some cases, an entity will be able to reasonably estimate a range of its liability very early in the process because the site situation is common or similar to situations at other sites with which the entity has been associated (for example, the remediation involves only the removal of underground storage tanks in accordance with the underground storage tank program). In such cases, the criteria for recognition would be met and the liability shall be recognized. In other cases, however, the entity may have insufficient information to reasonably estimate the minimum amount in the range of its liability. In these cases, the criteria for recognition would not be met at this time.
    
2.  b
    
    Receipt of [unilateral administrative order](https://asc.understandingaccounting.org/glossary/u/#unilateral-administrative-order "Order issued unilaterally by the Environmental Protection Agency under section 106(a) of the Comprehensive Environmental Response, Compensation, and Liability Act of 1980 to potentially responsible parties, or to nonpotentially responsible parties such as adjacent landowners, requiring them to take a response action. Unilateral administrative orders contain findings of fact and conclusions of law, and they specify the work to be performed and the Environmental Protection Agency's right to take over the work in the event of noncompliance, inadequate performance, or an emergency. A unilateral administrative order does not allocate conduct required by the order between individual potentially responsible parties; however, the Environmental Protection Agency may issue carve-out orders requiring individual potentially responsible parties to perform specific actions. Also referred to as a section 106 order."). The Resource Conservation and Recovery Act analogue is, generally, interim corrective measures. An entity may receive a unilateral administrative order compelling it to take a response action at a site or risk penalties of up to four times the cost of the response action. Such response actions may be relatively limited actions, such as the performance of a remedial investigation and feasibility study or performance of a [removal action](https://asc.understandingaccounting.org/glossary/r/#removal-action "Under the Comprehensive Environmental Response, Compensation, and Liability Act of 1980, generally short-term actions taken to respond promptly to an urgent need. The cleanup or removal of released hazardous substances from the environment; actions in response to the threat of release; actions that may be necessary to monitor, assess, and evaluate the release or threat; disposal of removed material; or other actions needed to prevent, minimize, or mitigate damage to public health or welfare or to the environment. Removal also includes, without being limited to, security fencing or other measures to limit access; provision of alternative water supplies; temporary evacuation and housing of threatened individuals not otherwise provided for; and any emergency assistance provided under the Disaster Relief Act."), or they may be broad actions such as remediating a site. Under section 106 of Superfund, the Environmental Protection Agency must find that an "imminent and substantial endangerment" exists at the site before such an order may be issued. No preenforcement review by a court is authorized under Superfund if an entity elects to challenge a unilateral administrative order. The ability to estimate costs resulting from unilateral administrative orders varies with factors such as site complexity and the nature and extent of the work to be performed. The benchmarks that follow should be considered in evaluating the ability to estimate such costs insofar as the actions required by the unilateral administrative order involve these benchmarks. The cost of performing the requisite work generally is estimable within a range, and recognition of an environmental remediation liability for costs of removal actions generally should not be delayed beyond this point.
    
3.  c
    
    Participation, as a potentially responsible party, in the remedial investigation-feasibility study. The Resource Conservation and Recovery Act analogue is Resource Conservation and Recovery Act facility investigation. At this stage, the entity and possibly others have been identified as potentially responsible parties and have agreed to pay the costs of a study that will investigate the extent of the environmental impact of the [release](https://asc.understandingaccounting.org/glossary/r/#release "Related to Superfund: any spilling, leaking, pumping, pouring, emitting, emptying, discharging, injecting, escaping, leaching, dumping, or disposing into the environment. Includes the abandonment or discarding of barrels, containers, and other closed receptacles containing any hazardous substance, pollutant, or contaminant. The law provides for several exclusions. Release also means the substantial threat of release.") or threatened release of hazardous substances and identify site-remediation alternatives. Further, the total cost of the remedial investigation-feasibility study generally is estimable within a reasonable range. In addition, the identification of other potentially responsible parties and their agreement to participate in funding the remedial investigation-feasibility study typically provides a reasonable basis for determining the entity's allocable share of the cost of the remedial investigation-feasibility study. At this stage, additional information may be available regarding the extent of environmental impact and possible remediation alternatives. This additional information, however, may or may not be sufficient to provide a basis for reasonable estimation of the total remediation liability. At a minimum, the entity should recognize its share of the estimated total cost of the remedial investigation-feasibility study. As the remedial investigation-feasibility study proceeds, the entity's estimate of its share of the total cost of the remedial investigation-feasibility study can be refined. Further, additional information may become available based on which the entity can refine its estimates of other components of the liability or begin to estimate other components. For example, an entity may be able to estimate the extent of environmental impact at a site and to identify existing alternative remediation technologies. An entity may also be able to identify better the extent of its involvement at the site relative to other potentially responsible parties; the universe of potentially responsible parties may be identified; negotiations among potentially responsible parties and with federal and state Environmental Protection Agency representatives may occur; and information may be obtained that materially affects the agreed-upon method of remediation.
    
4.  d
    
    Completion of feasibility study. The Resource Conservation and Recovery Act analogue is corrective measures study. At substantial completion of the feasibility study, both a minimum remediation liability and the entity's allocated share generally will be reasonably estimable. The feasibility study should be considered substantially complete no later than the point at which the potentially responsible parties recommend a proposed course of action to the Environmental Protection Agency. If the entity had not previously concluded that it could reasonably estimate the remediation liability (the best estimate or, if no amount within an estimated range of loss was a better estimate than any other amount in the range, the minimum amount in the range), recognition should not be delayed beyond this point, even if uncertainties, for example, about allocations to individual potentially responsible parties and potential recoveries from third parties, remain.
    
5.  e
    
    Issuance of record of decision. The Resource Conservation and Recovery Act analogue is approval of corrective measures study. At this point, the Environmental Protection Agency has issued its determination specifying a preferred remedy. Normally, the entity and other potentially responsible parties have begun, or perhaps completed, negotiations, litigation (see paragraphs
    
    [410-30-35-8 through 35-11](https://asc.understandingaccounting.org/asc/410/30/#410-30-35-8)
    
    ), or both for their allocated share of the remediation liability. Accordingly, the entity's estimate normally can be refined based on the specified preferred remedy and a preliminary allocation of the total remediation costs.
    
6.  f
    
    Remedial design through operation and maintenance, including postremediation monitoring. The Resource Conservation and Recovery Act analogue is corrective measures implementation. During the design phase of the remediation, engineers develop a better sense of the work to be done and are able to provide more precise estimates of the total remediation cost. Further information likely will become available at various points until the site is delisted, subject only to postremediation monitoring. The entity should continue to refine and recognize its best estimate of its final obligation as this additional information becomes available.

Those costs may be capitalized if recoverable but only if any one of the following criteria is met:

1.  a
    
    The costs extend the life, increase the capacity, or improve the safety or efficiency of property owned by the entity. For purposes of this criterion, the condition of that property after the costs are incurred must be improved as compared with the condition of that property when originally constructed or acquired, if later.
    
2.  b
    
    The costs mitigate or prevent environmental contamination that has yet to occur and that otherwise may result from future operations or activities. In addition, the costs improve the property compared with its condition when constructed or acquired, if later.
    
3.  c
    
    The costs are incurred in preparing for sale that property currently held for sale.

This Subtopic requires that tangible assets acquired to clean a particular spill not be charged to expense immediately. Rather, to the extent that those tangible assets have future uses, they may be capitalized. Example 5 (see paragraph [410-30-55-18](https://asc.understandingaccounting.org/asc/410/30/#410-30-55-18)) illustrates this guidance.

At the early stages of the remediation process, environmental remediation liabilities are not easily quantified, due in part to their uncertainties. As a practical matter, the range of an estimated remediation liability will be defined and refined as events in the remediation process occur. The environmental remediation liability recorded by an entity should be based on that entity's estimate of its allocable share of the joint and several remediation liability. The estimation of an entity's allocable share of the joint and several remediation liability (see paragraph [410-30-55-4](https://asc.understandingaccounting.org/asc/410/30/#410-30-55-4)) for a site requires an entity to do all of the following:

1.  a
    
    Identify the [potentially responsible parties](https://asc.understandingaccounting.org/glossary/p/#potentially-responsible-party "Any individual, legal entity, or government—including owners, operators, transporters, or generators—potentially responsible for, or contributing to, the environmental impacts at a Superfund site. The Environmental Protection Agency has the authority to require potentially responsible parties, through administrative and legal actions, to remediate such sites. At early stages of the remediation process, the list of potentially responsible parties may be limited to a handful of entities that either were significant contributors of waste to the site or were easy to identify, for example, because of their proximity to the site or because of labeled material found at the site. As further investigation of the site occurs and as remediation activities take place, additional potentially responsible parties may be identified. Once identified, the additional potentially responsible parties would be reclassified from this category to either the participating potentially responsible party or recalcitrant potentially responsible party category. The total number of parties in this category and their aggregate allocable share of the remediation liability varies by site and cannot be reliably determined before the specific identification of individual potentially responsible parties. For example, some ultimately may be dropped from the potentially responsible party list because no substantive evidence is found to link them to the site. For others, substantive evidence eventually may be found that points to their liability. The presentation of that evidence to the entity would result in a reclassification of the party from this category of potentially responsible parties (sometimes referred to as hiding in the weeds) to either the participating potentially responsible party or recalcitrant potentially responsible party category.") for the site
    
2.  b
    
    Assess the likelihood that other potentially responsible parties will pay their full allocable share of the joint and several remediation liability
    
3.  c
    
    Determine the percentage of the liability that will be allocated to the entity.

For purposes of estimating an entity's allocable share of the joint and several remediation liability for a site, those parties that are potentially responsible for paying the remediation liability belong to one of the following five potentially responsible party categories:

1.  a
    
    [Participating potentially responsible parties](https://asc.understandingaccounting.org/glossary/p/#participating-potentially-responsible-party "A party to a Superfund site that has acknowledged potential involvement with respect to the site. Active potentially responsible parties may participate in the various administrative, negotiation, monitoring, and remediation activities related to the site. Others may adopt a passive stance and simply monitor the activities and decisions of the more involved potentially responsible parties. This passive stance could result from a variety of factors such as the entity's lack of experience, limited internal resources, or relative involvement at a site. This category of potentially responsible parties (both active and passive) is also referred to as players.")
    
2.  b
    
    [Recalcitrant potentially responsible parties](https://asc.understandingaccounting.org/glossary/r/#recalcitrant-potentially-responsible-party "A party whose liability with respect to a Superfund site is substantiated by evidence, but that refuses to acknowledge potential involvement with respect to the site. Recalcitrant potentially responsible parties adopt a recalcitrant attitude toward the entire remediation effort even though evidence exists that points to their involvement at a site. Some may adopt this attitude out of ignorance of the law; others may do so in the hope that they will be considered a nuisance and therefore ignored. Typically, parties in this category must be sued in order to collect their allocable share of the remediation liability; however, it may be that it is not economical to bring such suits because the parties' assets are limited. This category of potentially responsible parties is also referred to as nonparticipating potentially responsible parties.")
    
3.  c
    
    [Unproven potentially responsible parties](https://asc.understandingaccounting.org/glossary/u/#unproven-potentially-responsible-party "A party that has been identified as a potentially responsible party for a Superfund site by the U.S. Environmental Protection Agency or by an analogous state agency, but that does not acknowledge potential involvement with respect to the site because no evidence has been presented linking the party to the site. Also referred to as a hiding-in-the-weeds potentially responsible party.")
    
4.  d
    
    [Unknown potentially responsible parties](https://asc.understandingaccounting.org/glossary/u/#unknown-potentially-responsible-party "A party that has liability with respect to a Superfund site, but that has not yet been identified as a potentially responsible party by the Environmental Protection Agency or by an analogous state agency.")
    
5.  e
    
    [Orphan share potentially responsible parties](https://asc.understandingaccounting.org/glossary/o/#orphan-share-potentially-responsible-party "An identified potentially responsible party that cannot be located or that is insolvent. Some of these parties may be identified by the Environmental Protection Agency; others may be identified as the site is investigated or as the remediation is performed. However, no contributions will ever be made by these parties.").

An entity should assess the likelihood that each potentially responsible party will pay its allocable share of the joint and several remediation liability. That assessment should be based primarily on the financial condition of the participating potentially responsible party. This assessment requires the entity to gain an understanding of the financial condition of the other participating potentially responsible parties and to update and monitor this information as the remediation progresses. The entity shall include in its liability its share of amounts related to the site that will not be paid by other potentially responsible parties or the government.

The measurement of environmental remediation liabilities shall be based on the reporting entity's estimate of what it will cost to perform each of the elements of the remediation effort (determined in accordance with paragraphs

[410-30-30-11 through 30-15](https://asc.understandingaccounting.org/asc/410/30/#410-30-30-11)

) when those elements are expected to be performed. Although this approach is sometimes referred to as considering inflation, it does not simply rely on an inflation index (cost estimates submitted to the Environmental Protection Agency usually include a prescribed inflation factor) and should take into account factors such as productivity improvements due to learning from experience with similar sites and similar remedial action plans. In situations in which it is not practicable to estimate inflation and such other factors because of uncertainty about the timing of expenditures, a current-cost estimate would be the minimum in the range of the liability to be recorded until such time as these cost effects can be reasonably estimated.

Additional complexities arise if other potentially responsible parties are involved in an identified site. The costs associated with remediation of a site ultimately will be assigned and allocated among the various potentially responsible parties. The final allocation of costs may not be known, however, until the remediation effort is substantially complete, and it may or may not be based on an entity's relative direct responsibility at a site. An entity's final obligation depends, among other things, on the willingness of the entity and other potentially responsible parties to negotiate a cost allocation, the results of the entity's negotiation efforts, and the ability of other potentially responsible parties associated with the particular site to fund the remediation effort.

Potential recoveries of amounts expended for environmental remediation are distinguishable from the allocation of costs subject to [joint and several liability](https://asc.understandingaccounting.org/glossary/j/#joint-and-several-liability "Where liability is joint and several, any party deemed liable is potentially responsible for all of the associated costs. This scheme of liability means that any responsible party can potentially be liable for the entire cost of remediating a site, notwithstanding that the party is responsible for only a small amount of the total hazardous substances or waste at the site and did nothing improper."), which is discussed in paragraphs

[410-30-30-1 through 30-7](https://asc.understandingaccounting.org/asc/410/30/#410-30-30-1)

The amount of a potential recovery is measured based on available information and the specific situation (see paragraph [410-30-30-15](https://asc.understandingaccounting.org/asc/410/30/#410-30-30-15)). As indicated in paragraphs

[410-30-30-12 through 30-15](https://asc.understandingaccounting.org/asc/410/30/#410-30-30-12)

, measurement of a potential recovery requires consideration of transaction costs related to the receipt of the recovery. The time value of money shall be considered in the measurement of a potential recovery when the measurement of the liability considers the time value of money.

However, the time value of money should not be considered in the determination of the recorded amount of a potential recovery if the liability is not discounted and the timing of the recovery is dependent on the timing of the payment of the liability. In most circumstances, the point in time at which a liability for environmental remediation is both probable and reasonably estimable will precede the point in time at which any related recovery is probable of realization.

The measurement of the liability, or of a component of the liability, may be discounted to reflect the time value of money if the aggregate amount of the liability or component and the amount and timing of cash payments for the liability or component are fixed or reliably determinable. (Note that these criteria would not be met in situations in which paragraph [410-30-30-17](https://asc.understandingaccounting.org/asc/410/30/#410-30-30-17) permits use of a current-cost estimate.) For this purpose, the amount of the liability or component is the reporting entity's allocable share of the undiscounted joint and several liability for the remediation effort or of a component of that liability.

Furthermore, it is particularly difficult to substantiate the classification of environmental remediation costs as a component of nonoperating expenses. Because the events underlying the incurrence of the obligation relate to an entity's operations, remediation costs shall be charged against operations. Although charging the costs of remediating past environmental impacts against current operations may appear debatable because of the time between the contribution or transportation of waste materials containing hazardous substances to a site and the subsequent incurrence of remediation costs, environmental remediation-related expenses have become a regular cost of conducting economic activity. Accordingly, environmental remediation-related expenses shall be reported as a component of operating income in income statements that classify items as operating or nonoperating. Credits arising from recoveries of environmental losses from other parties shall be reflected in the same income statement line. Any earnings on assets that are reflected on the entity's financial statements and are earmarked for funding its environmental liabilities shall be reported as investment income.

Because environmental remediation costs have become increasingly significant, and because the accounting for many environmental loss contingencies often involves subjective judgments, disclosure of accrual benchmarks for remediation obligations is useful to further users' understanding of the entity's financial statements. Accordingly, entities are encouraged, but not required, to disclose the event, situation, or set of circumstances that generally triggers recognition of loss contingencies that arise out of the entity's environmental remediation-related obligations (for example, during or upon completion of the feasibility study). Also, entities are encouraged to disclose their policy concerning the timing of recognition of recoveries. (See Example 2 \[paragraph [410-30-55-14](https://asc.understandingaccounting.org/asc/410/30/#410-30-55-14)\].)

Uncertainties associated with environmental remediation loss contingencies are pervasive, and they often result in wide ranges of reasonably possible losses with respect to such contingencies. Further, resolution of the uncertainties and the cash-flow effects of the loss contingencies often occur over a span of many years. Accordingly, this Subtopic encourages, but does not require, additional specific disclosures with respect to environmental remediation loss contingencies that would be useful to further users' understanding of the entity's financial statements.

Whether notification by regulatory authorities in relation to particular environmental laws and regulations constitutes the assertion of a claim is a matter of legal determination. If an entity concludes that it has no current [legal obligation](https://asc.understandingaccounting.org/glossary/l/#legal-obligation "An obligation that a party is required to settle as a result of an existing or enacted law, statute, ordinance, or written or oral contract or by legal construction of a contract under the doctrine of promissory estoppel.") to remediate a situation of probable or possible environmental impact, then in accordance with paragraph [450-20-50-6](https://asc.understandingaccounting.org/asc/450/20/#450-20-50-6) no disclosure is required. However, if an entity is required by existing laws and regulations to report the [release](https://asc.understandingaccounting.org/glossary/r/#release "Related to Superfund: any spilling, leaking, pumping, pouring, emitting, emptying, discharging, injecting, escaping, leaching, dumping, or disposing into the environment.

Release also means the substantial threat of release.") of hazardous substances and to begin a remediation study or if assertion of a claim is deemed probable, the matter would represent a loss contingency subject to the disclosure provisions of paragraphs

[450-20-50-3 through 50-4](https://asc.understandingaccounting.org/asc/450/20/#450-20-50-3)

Financial statements may include a contingency conclusion that addresses the estimated total unrecognized exposure to environmental remediation and other loss contingencies. Such contingency conclusions may state, for example, that "management believes that the outcome of these uncertainties should not have \[or "may have"\] a material adverse effect on the financial condition, cash flows, or operating results of the entity." Alternatively, the disclosure may indicate that the adverse effect could be material to a particular financial statement or to results and cash flows of a quarterly or annual reporting period.

Entities may wish to provide a description of the general applicability and impact of environmental laws and regulations upon their business and how the existence of such laws and regulations may give rise to loss contingencies for future environmental remediation. Such disclosures often acknowledge the uncertainty of the effect of possible future changes to environmental laws and their application, and they are frequently made on an aggregated basis, considering the entity's total exposures for all its environmental sites.

There are numerous ways to allocate liabilities among potentially responsible parties. The four principal factors considered in a typical allocation process are the following:

1.  a
    
    Elements of fair share. Examples are the amount of waste based on volume; the amount of waste based on mass, type of waste, toxicity of waste; the length of time the site was used.
    
2.  b
    
    Classification of potentially responsible party. Examples are site owner, site operator, transporter of waste, generator of waste.
    
3.  c
    
    Limitations on payments. This characteristic includes any statutory or regulatory limitations on contributions that may be applicable to a potentially responsible party. For example, in the reauthorization of the Comprehensive Environmental Response, Compensation, and Liability Act, it has been proposed that the statute limit the contribution of a municipality to 10 percent of the total remediation liability, irrespective of the municipality's allocable share.
    
4.  d
    
    Degree of care. This refers to the degree of care exercised in selecting the site or in selecting a transporter.

Potentially responsible parties may reach an agreement among themselves as to the allocation method and percentages to be used, they may hire an allocation consultant whose conclusions may or may not be binding, or they may request a nonbinding allocation of responsibility from the Environmental Protection Agency. The allocation method or percentages used may change as the remediation project moves forward. An agreement to reallocate the preliminarily allocated liability at the end of the remediation project may exist, or the allocation percentages may be adjusted during the project to reflect prior allocations that subsequently are agreed to have been inequitable. This implementation guidance illustrates paragraph [410-30-30-1](https://asc.understandingaccounting.org/asc/410/30/#410-30-30-1).

This implementation guidance addresses the criterion in paragraph [410-30-30-19(b)](https://asc.understandingaccounting.org/asc/410/30/#410-30-30-19) involving the dependency of the timing of the recovery on the timing of the payment of the liability. That criterion would usually be met, for example, if an insurance entity agrees, in accordance with the terms of an insurance contract, to reimburse the reporting entity for all or a percentage of the remediation costs incurred by the reporting entity as the reporting entity expends money to satisfy its obligation. That criterion likely would not be met, for example, in a lump-sum buyout by an insurance entity of contested coverage.

Ace Oil Company is a distributor of heating oil with four storage and distribution facilities located in Anystate. Federal, state, and local laws and regulations govern the operation of the entity's facilities. The entity has determined that, beginning in the coming year, a significant number of its storage tanks and a significant amount of its other equipment will need to be removed, replaced, or modified to satisfy regulations that go into effect in varying stages over the next seven years. In addition, the entity has a present obligation to decontaminate the soil in the near term at its largest facility.

The entity hired a consultant to evaluate the technological, regulatory, and legal factors involved. Based on the consultant's findings, the entity estimated that total environmental expenditures over the next 7 years related to the tanks and equipment will aggregate approximately $5 million. Of this amount, approximately $4.75 million represents capital expenditures, which are expected to be recoverable through operations. The existing tanks have a net book value of $500,000, and the equipment has a net book value of $475,000. The cost of soil decontamination is estimated to be at least $1 million, which is material to the entity's operations, and may be as high as $3 million. Exposure to legal liability to third parties is considered remote.

The entity would disclose the following. (The italicized text illustrates the voluntary disclosure that is encouraged by paragraph [275-10-50-9](https://asc.understandingaccounting.org/asc/275/10/#275-10-50-9).)

-   The entity will begin a project to decontaminate the soil at its Anytown, Anystate facility in the coming year. The entity estimates the cost of decontamination to total at least $1 million and has accrued that amount as an operating expense in the current year. The ultimate cost, however, _will depend on the extent of contamination found as the project progresses and_ may be as much as $3 million. The entity expects decontamination to be substantially completed within one year.

This disclosure informs financial statement users of the existence of the soil contamination problem at the financial statement date and indicates that the liability is susceptible to change in the near term. This Subtopic does not require disclosure of the capital commitment because it is not a present obligation for which an estimate is reflected in the entity's financial statements.

Although, in this Example, the near-term nature of the possible change is indicated by a statement that the entity expects decontamination to be substantially completed within one year, an expectation that decontamination will take more than one year to complete would not preclude the estimate from being susceptible to near-term change. In such cases, the disclosure could be worded to specifically refer to the near term.

This Example illustrates the guidance in paragraph [410-30-50-10](https://asc.understandingaccounting.org/asc/410/30/#410-30-50-10) for disclosure for a situation in which all of the following conditions exist:

1.  a
    
    An entity is involved in a single environmental site at which a number of potential outcomes may occur.
    
2.  b
    
    There is a probable, reasonably estimable recovery from a third party.
    
3.  c
    
    The entity has accrued for the most likely outcome within a range of possible outcomes for each component.
    
4.  d
    
    The nature of the amounts accrued for remediation and the related probable recovery are necessary to be disclosed in order for the financial statements not to be misleading.
    
5.  e
    
    There is a reasonably possible loss exposure in excess of the amount accrued that is material and it is reasonably possible that a change in estimate that would be material to the financial statements will occur in the near term.

The entity would make the following disclosure (information that is enclosed in brackets is not required).

-   Entity A has been notified by the Environmental Protection Agency that it is a potentially responsible party under Superfund legislation \[with respect to XYZ site in Sometown, USA, a [disposal](https://asc.understandingaccounting.org/glossary/d/#disposal "Related to the Comprehensive Environmental Response, Compensation, and Liability Act of 1980 and the Resource Conservation and Recovery Act of 1976: under the Resource Conservation and Recovery Act of 1976, the discharge, deposit, injection, dumping, spilling, leaking, or placing of any solid waste or hazardous waste into or on any land or water so that such solid waste or hazardous waste or any constituent thereof may enter the environment or be emitted into the air or discharged into any waters, including groundwaters. Similarly under the Comprehensive Environmental Response, Compensation, and Liability Act of 1980 with regard to hazardous substances.") site previously used in its chemical-fertilizer business. The Environmental Protection Agency has also identified 10 other potentially responsible parties for XYZ. A remedial investigation and feasibility study has been completed, and the results of that study have been forwarded to the Environmental Protection Agency. The study indicates a range of viable remedial approaches, but agreement has not yet been reached with the Environmental Protection Agency on the final remediation approach. The potentially responsible party group has preliminarily agreed to an allocation that sets Entity A's share of the cost of remediating XYZ site at 6 percent.\] Entity A has accrued its best estimate of its obligation with respect to the site at December 31, 199X, \[which is $10 million and which is included in long-term liabilities and is expected to be disbursed over the next 10 years. If certain of the potentially responsible parties are ultimately not able to fund their allocated shares or the Environmental Protection Agency insists on a more expensive remediation approach,\] Entity A could incur additional obligations of up to $7 million. It is reasonably possible that Entity A's recorded estimate of its obligation may change in the near term.
    
-   With respect to the environmental obligation discussed above, the site was acquired in 1982, and, in connection with that acquisition, the former owner partially indemnified Entity A for environmental impacts occurring before the acquisition. \[Based on existing documentation indicating the years in which the business shipped wastes to XYZ and the terms of the indemnification in the acquisition agreement,\] Entity A \[believes it is probable that it will recover from the prior owners 50 percent of its allocated remediation costs for XYZ and, accordingly,\] has recorded a receivable of $5 million at December 31, 199X.

This Example illustrates the guidance in paragraph [410-30-50-11](https://asc.understandingaccounting.org/asc/410/30/#410-30-50-11). An entity would make the following disclosure of a probable but not yet reasonably estimable environmental remediation loss contingency (information that enclosed in brackets is not required).

-   Entity A has been notified by the Environmental Protection Agency that it is a potentially responsible party with respect to environmental impacts \[identified at the XYZ site in Sometown, USA. Several meetings have been held with the Environmental Protection Agency and the other identified potentially responsible parties, and a remedial investigation has recently commenced\]. Although a loss is probable, it is not possible at this time to reasonably estimate the amount of any obligation for remediation \[of XYZ site\] that would be material to Entity A's financial statements \[because the extent of environmental impact, allocation among the potentially responsible parties, remediation alternatives (which could involve no or minimal efforts), and concurrence of the regulatory authorities have not yet advanced to the stage where a reasonable estimate of any loss that would be material to the entity can be made\]. \[A reasonable estimate of a material obligation, if any, is expected to be possible in 199X.\]

    "Environmental Contamination, Treatments" Evaluation of Criteria Tanker Oil Spill: A. Clean up waterway and beachfront 1. Costs to clean up the waterway and beachfront are not eligible for consideration under the first criterion because the oil company does not own the property. 2. The cleanup of the waterway and beachfront does not mitigate or prevent a future oil spill from future operations. "3. The waterway and beachfront are not owned assets and, therefore, the third criterion does not apply." Conclusion: Costs incurred for cleanup and restoration in connection with the oil spill should be charged to expense. B. Reinforce tanker's hull to reduce risk of future spill 1. Reinforcing the hull improves the tanker's safety compared to when the tanker was originally constructed or acquired. 2. Reinforcing the hull mitigates the risk that the tanker will experience a similar oil spill during future operations and improves the tanker's safety compared to when the tanker was originally constructed or acquired. Conclusion: The costs incurred in connection with reinforcing the tanker's hull may be capitalized under either the first or second criterion.

    "Environmental Contamination, Treatments" Evaluation of Criteria Rusty Chemical Storage Tank: A. Remove rust that developed during ownership 1. Removing the rust has not improved the tank compared with its condition when built or acquired. "2. Removing the rust has mitigated the possibility of future leaks. However, removing the rust has not improved the tank compared with its condition when built or acquired." Conclusion: Rust removal costs should be expensed unless the tank is currently held for sale and the costs were incurred to prepare the tank for sale. B. Apply rust prevention chemicals 1. The application of rust prevention chemicals has improved the tank's condition compared with its condition when built or acquired. 2. Rust prevention chemicals mitigate the possibility that future rust will cause leaks and also improve the tank's condition compared with its condition when built or acquired. Conclusion: The costs of applying the rust prevention chemicals may be capitalized under either the first or second criterion.

    "Environmental Contamination, Treatments" Evaluation of Criteria Air Pollution Caused by Manufacturing Activities: A. Acquire and install pollution control equipment 1. The pollution control equipment improves the safety of the plant compared with its condition when built or acquired. 2. The pollution control equipment mitigates or prevents air pollution that has yet to occur but that may otherwise result from future operation of the plant and improves the safety of the plant compared with its condition when built or acquired. Conclusion: Costs associated with acquisition and installation of the pollution control equipment may be capitalized under either the first or second criterion. B. Pay fines for violations of the Clean Air Act "1. Payment of fines does not extend the plant's life, increase its capacity, or improve its efficiency or safety." 2. Payment of fines does not mitigate or prevent pollution that has yet to occur but that may otherwise result from future operation of the plant. "Conclusion: Fines paid in connection with violations of the Clean Air Act should be charged to expense. Even if the plant is currently held for sale, the fines should be charged to expense because the costs would not have been incurred to prepare the plant for sale."

    "Environmental Contamination, Treatments" Evaluation of Criteria Soil Contamination Caused by an Operating Garbage Dump: A. Refine soil on dump property "1. The life of a garbage dump is not extended by refining its soil. Further, the condition of the soil after refining will not be improved over its condition when the garbage dump was constructed or acquired. Removal of the toxic waste restores the soil to its original uncontaminated condition." "2. Removal of toxic waste from the soil addresses an existing environmental concern. It also prevents that waste from leaching in the future. However, removing the waste does not mitigate or prevent future operations from creating future toxic waste. The risk will continue regardless of how much of the existing soil is refined." Conclusion: Soil refinement costs should be charged to expense unless the garbage dump is currently held for sale and the costs were incurred to prepare the garbage dump for sale. B. Install liner "1. The liner does not extend the useful life or improve the efficiency or capacity of the garbage dump. However, the liner has improved the garbage dump's safety compared to when the dump was constructed or acquired." "2. The liner addresses an existing and potential future problem. In this example, the garbage dump contains toxic waste from past operations and will likely generate toxic waste during future operations. The liner partly addresses the existing environmental problem by preventing future leaching of existing toxic waste into the soil. The liner also mitigates or prevents leaching of toxic waste that may result from garbage dumping in future periods and has improved the garbage dump's safety compared to when the dump was constructed or acquired." Conclusion: The liner may be capitalized under either the first or second criterion.

    "Environmental Contamination, Treatments" Evaluation of Criteria Water Well Contamination Caused by Chemicals That Leaked into Wells Containing Water That Will Be Used in Future Beer Production: A. Neutralize water in wells "1. The treatment does not extend the life of the wells, increase their capacity, or improve efficiency. The condition of the water is not safer after the treatment compared to when the wells were initially acquired." "2. By neutralizing the water, the possibility of future contamination of the wells from future operations has not been mitigated or prevented." Conclusion: Costs incurred to neutralize well water should be charged to expense unless the wells were held for sale and the costs were incurred to prepare the wells for sale. B. Install water filters 1. The water filters improve the safety of the wells compared with their uncontaminated state when built or acquired. "2. The water filters address future problems that may result from future operations. Since the water filters are effective in filtering environmental contamination, they mitigate the effect of spilling new contaminants into the wells during future operations. In addition, the water filters represent an improvement compared with the wells' original condition without water filters." Conclusion: The water filtering system may be capitalized under either the first or the second criterion.

Conclusion: Soil refining costs should be charged to expense unless the property is currently held for sale and the costs were incurred to prepare the property for sale. B. Encase tanks so as to prevent future leaks from contaminating surrounding soil "1. In some cases, encasement may increase the life of the tanks because of their increased resistance to corrosion, leaking, etc. In other situations, the treatment may not increase the life of the tanks. However, the encasement has improved the tanks' safety compared with their condition when built or acquired." "2.

In 1986, the entity received an information request from the Environmental Protection Agency pursuant to section 104 of the Comprehensive Environmental Response, Compensation, and Liability Act of 1980. The information request stated that the Environmental Protection Agency believed that hazardous substances at a site, now listed by the Environmental Protection Agency on its National Priorities List, were generated at XYZ's plant. XYZ was named as a potentially responsible party and was directed by the Environmental Protection Agency, under penalty of law, to search its records exhaustively and answer a series of questions possibly implicating it directly to the site, or indirectly by its having used one or more transporters the Environmental Protection Agency said it was also investigating.

XYZ searched its records as directed and determined late in 1986 that it had, in fact, contributed hazardous substances to the site. XYZ could not, however, determine how significant the hazardous substances it had sent to the site were in relation to the total population of hazardous substances at the site. The minimum remediation cost, including a minimum amount of legal fees, that XYZ was able to estimate was not material to its financial statements. XYZ was able, however, to determine that it was reasonably possible that its ultimate liability could be material.

In 1987 the Environmental Protection Agency identified a number of waste generators, transporters, and site owner-operators as likely potentially responsible parties. The identified potentially responsible parties were invited to a meeting at which government lawyers requested that one or more of the potentially responsible parties voluntarily perform a remedial investigation-feasibility study to evaluate existing site conditions (including a public health and ecological risk assessment) and to develop a proposed array of remedial alternatives from which the Environmental Protection Agency would select a remedy and demand that it be implemented. Standardized Environmental Protection Agency terms and conditions, stipulated penalty provisions, and indeterminate scope of work elements inhibited voluntary agreement among the potentially responsible parties, and so a [consent decree](https://asc.understandingaccounting.org/glossary/c/#consent-decree "A legal document, approved by a judge, that formalizes an agreement reached between the Environmental Protection Agency and potentially responsible parties through which potentially responsible parties will conduct all or part of a remedial action at a Superfund site; cease or correct actions or processes that are polluting the environment; or otherwise comply with regulations where potentially responsible parties' failure to comply caused the Environmental Protection Agency to initiate regulatory enforcement actions. The consent decree describes the actions potentially responsible parties will take and may be subject to a public comment period.") was not achieved.

In 1988 the Environmental Protection Agency asserted the existence of "imminent and substantial endangerment" at the site early in 1988 under section 106 of the Comprehensive Environmental Response, Compensation, and Liability Act, and it issued a [unilateral administrative order](https://asc.understandingaccounting.org/glossary/u/#unilateral-administrative-order "Order issued unilaterally by the Environmental Protection Agency under section 106(a) of the Comprehensive Environmental Response, Compensation, and Liability Act of 1980 to potentially responsible parties, or to nonpotentially responsible parties such as adjacent landowners, requiring them to take a response action. Unilateral administrative orders contain findings of fact and conclusions of law, and they specify the work to be performed and the Environmental Protection Agency's right to take over the work in the event of noncompliance, inadequate performance, or an emergency. A unilateral administrative order does not allocate conduct required by the order between individual potentially responsible parties; however, the Environmental Protection Agency may issue carve-out orders requiring individual potentially responsible parties to perform specific actions. Also referred to as a section 106 order.") to the potentially responsible party with the deepest pockets—XYZ—to undertake the remedial investigation-feasibility study.

Because triple damages are authorized under section 106 of the Comprehensive Environmental Response, Compensation, and Liability Act, XYZ agreed to conduct the remedial investigation-feasibility study specified in the order and demanded that other identified potentially responsible parties participate in the effort. XYZ initially estimated the cost that would be incurred to perform the remedial investigation-feasibility study to be between $1 million and $2 million. Based on the limited information that was available about the site, information that XYZ had about its contribution to the site, and the number and financial condition of other potentially responsible parties, XYZ initially estimated that its ultimate share of this cost would prove to be in the range of 20 percent to 50 percent. XYZ also estimated that it would incur legal costs related to the remediation effort of $200,000 to $2 million in addition to any legal costs that might be incurred by any potentially responsible party group that might be formed. No amounts within any of these ranges were considered to be better estimates than any other amounts within any of these ranges. Because of a lack of information about the type and extent of the remediation effort that could be required, no range of cost of the overall remediation effort could be developed at this time.

Under threat of a contribution lawsuit by XYZ, a potentially responsible party group was formed late in 1988. The potentially responsible party group had the following three objectives:

1.  a
    
    To implement the requirements of the unilateral administrative order in the most cost-effective and scientifically valid way
    
2.  b
    
    To raise money and allocate costs among the potentially responsible parties willing to perform the work based on the types and relative quantities of wastes shipped to the site or another agreed-upon formula
    
3.  c
    
    To recover costs from nonparticipating potentially responsible parties, if possible.

Because of the lack of a good data base of factual information upon which to make sound allocation decisions agreeable to all, outside arbitration was used in 1989 to allocate fair share costs among participating potentially responsible parties. The arbitrator preliminarily apportioned 65 percent of the costs for the site to the four participating potentially responsible parties, as follows.

Twenty-five percent of the site was determined to be the [orphan share](https://asc.understandingaccounting.org/glossary/o/#orphan-share "Equitable share of liability for response or remediation costs attributed to orphan-share potentially responsible parties, or the amount by which the equitable share of liability for response or remediation costs attributable to other parties exceeds the amount for which those parties have settled their liability."), for which no potentially responsible party could be identified. Ten percent was attributed to two recalcitrant (nonparticipating) potentially responsible parties, and there was insufficient information to overcome the presumption that costs will be allocated only among the participating potentially responsible parties.

XYZ gained some understanding of the other participating potentially responsible parties' financial condition and believed each of them was able and likely to pay its full share of the costs of the remedial investigation-feasibility study.

The remedial investigation-feasibility study was substantially completed in 1991. No changes were made to the potentially responsible parties allocation percentages as a result of the remedial investigation-feasibility study completion. The potentially responsible party group's initial estimate of the cost of implementing the remedy expected to be required by the Environmental Protection Agency was $25 million to $30 million. No amount within this range was considered to be a better estimate than any other amount within the range. This estimate included estimates of the cost of all elements of the remediation effort, including common legal, engineering, construction, monitoring, operation and maintenance costs (including postremediation monitoring for a period of 30 years), and so forth.

XYZ believed that potentially responsible party No. 2 and potentially responsible party No. 4 could and would pay their full shares of the cost of the remediation effort. Potentially responsible party No. 3, however, indicated that, because of its deteriorating financial position, it would likely be unable to pay more than two-thirds of its 15 percent share and none of its allocated amount attributed to the orphan and recalcitrant shares, or 10 percent of those costs. XYZ shared potentially responsible party No. 3's views about potentially responsible party No. 3's ability to pay.

Three years after site studies began, the Environmental Protection Agency and its outside contractors evaluated the reports submitted under the terms of the unilateral administrative order. A record of decision was issued by the Environmental Protection Agency on September 30, 1992, in which remedial actions based on the remedial investigation-feasibility study were selected and cost estimates were presented. The potentially responsible parties were requested to voluntarily implement the record of decision and again sign up to the terms demanded by the government. No preenforcement federal court review is permitted, even if the remedy specified in the record of decision is scientifically flawed, unattainable by available, proven technology, non-cost-effective, or open-ended. The potentially responsible parties had the following choices: perform the remedy specified in the record of decision voluntarily, or refuse to do work, in which case the Environmental Protection Agency would either issue another unilateral administrative order or perform the work using its contractor procurement systems and sue the potentially responsible parties for cost recovery. The potentially responsible parties agreed to perform the remedy specified in the record of decision and entered into a consent judgment.

Note that the law requires the Environmental Protection Agency to review the record of decision and remedy within five years of its implementation by the potentially responsible parties. If the objectives of the record of decision have not been attained, the Environmental Protection Agency may make additional demands on the potentially responsible parties. If one or more potentially responsible parties believe they have paid a disproportionate share of the costs, they may track down other potentially responsible parties and sue them in a contribution action. Although requests for reimbursement from Superfund can also be made for allocations attributed to unidentified or unknown parties (the orphan share) under certain conditions, this is not usually allowed by terms and conditions of consent order settlements withthe Environmental Protection Agency.

Subtopic 450-20 requires accrual of a loss contingency when it is probable that a liability has been incurred and the amount of the loss can be reasonably estimated. Receipt in 1986 of an information request did not establish that a liability was probable because, notwithstanding the Environmental Protection Agency's interest in XYZ's connection, if any, to the site, it had not been established that XYZ was in fact associated with the site. As noted in paragraph [410-30-25-4](https://asc.understandingaccounting.org/asc/410/30/#410-30-25-4), however, receipt of notification that an entity may be a potentially responsible party compels the entity to action.

When XYZ determined late in 1986 that it had, in fact, contributed hazardous substances to the site, the liability became probable. The criteria for recognition had not yet been met, however, because XYZ did not have sufficient information to reasonably estimate a minimum amount in the range of its liability that would be material to its financial statements. Disclosure of the nature of the contingency and a statement that an estimate of the loss or range of loss cannot be made was required under Subtopic 450-20.

Because other potentially responsible parties had agreed during 1988 to participate in the remedial investigation-feasibility study effort, they are considered to be participating potentially responsible parties. Neither the fact that the unilateral administrative order named only XYZ nor the fact that a preliminary cost-sharing formula had not yet been determined by the arbitrator should have required XYZ to accrue more than its estimated allocable share of the minimum estimated liability.

Although no recognition benchmarks were achieved in 1989 or 1990, XYZ should have refined its estimate of its liability as additional significant information became available. For example, in 1989, when the preliminary cost-sharing formula was developed by the arbitrator and the estimate of the cost of the remedial investigation-feasibility study was revised, XYZ should have refined its estimate of its share of the cost of the remedial investigation-feasibility study and adjusted its liability to $719,231, less any amounts already expended. $719,231 is computed as follows.

By the time the feasibility study was substantially completed in 1991, XYZ should have adjusted its liability to reflect its estimated share of the minimum amount of the overall remediation liability. Based on the facts presented, this amount should be $9,350,000, less any amounts already expended. $9,350,000 is computed as follows.

The estimate of the environmental remediation liability should be further refined when the record of decision is issued in 1992 and at various other points when additional information becomes available.

The measurement of the remediation liability should not have been discounted at any point during the period under discussion because the amount of the obligation and the amount and timing of cash payments were not fixed or reliably determinable.

{
  "summary": "ASC 410-980 explains how rate-regulated entities apply the asset retirement obligation (ARO) model of Subtopic 410-20. Because rate regulation may allow recovery of retirement costs on a timing pattern different from GAAP ARO cost recognition, a regulated entity that meets the requirements of Topic 980 recognizes a regulatory asset or regulatory liability for that timing difference. Capitalized asset retirement cost is included in long-lived asset impairment testing on the same basis as for any other entity.",

    "Nuclear plant decommissioning costs are incurred costs imposed by regulation or statute (similar to the obligation to restore land after strip mining), so paragraph 980-405-25-1(b) does not address those costs (410-980-25-1).",
    "Rate-regulated entities may recover retirement costs in customer rates on a timing pattern that differs from period cost recognition under Subtopic 410-20, and a timing difference can also arise when retirement costs are included in amounts charged to customers but no liability is recognized (410-980-25-2).",
    "If the requirements of Topic 980 are met, the regulated entity recognizes a regulatory asset or regulatory liability for the difference between financial reporting recognition of ARO period costs and rate-making recognition (410-980-25-2).",
    "Some retirement costs recovered in rates arise from AROs within the scope of Subtopic 410-20 and others do not; only the former follow that Subtopic (410-980-25-2).",

Nuclear plant decommissioning costs are incurred costs in the current accounting framework. Those costs and the related liabilities are imposed by regulation or statute, similar to the liability to restore the land after strip mining. Accordingly, paragraph [980-405-25-1(b)](https://asc.understandingaccounting.org/asc/405/980/#405-980-25-1) does not address those costs.

Many rate-regulated entities currently provide for the costs related to the retirement of certain long-lived assets in their financial statements and recover those amounts in rates charged to their customers. Some of those costs result from asset retirement obligations within the scope of Subtopic 410-20; others result from costs that are not within the scope of that Subtopic. The amounts charged to customers for the costs related to the retirement of long-lived assets may differ from the period costs recognized in accordance with that Subtopic and, therefore, may result in a difference in the timing of recognition of period costs for financial reporting and rate-making purposes. An additional recognition timing difference may exist when the costs related to the retirement of long-lived assets are included in amounts charged to customers but liabilities are not recognized in the financial statements. If the requirements of this Topic are met, a regulated entity also shall recognize a regulatory asset or liability for differences in the timing of recognition of the period costs associated with asset retirement obligations for financial reporting pursuant to that Subtopic and rate-making purposes.

The following is the text of SAB Topic 10.F, Presentation of Liabilities for Environmental Costs.

-   Facts: A public utility company determines that it is obligated to pay material amounts as a result of an environmental liability. These amounts may relate to, for example, damages attributed to clean-up of hazardous wastes, reclamation costs, fines, and litigation costs.
    
-   Question 1: May a rate-regulated enterprise present on its balance sheet the amount of its estimated liability for environmental costs net of probable future revenue resulting from the inclusion of such costs in allowable costs for rate-making purposes?
    
-   Interpretive Response: No. Statement 71 \[paragraph [980-340-25-1](https://asc.understandingaccounting.org/asc/340/980/#340-980-25-1)\] specifies the conditions under which rate actions of a regulator can provide reasonable assurance of the existence of an asset. The staff believes that environmental costs meeting the criteria of paragraph 9 <sup class="ph sup">FN6</sup> of Statement 71 \[paragraph [980-340-25-1](https://asc.understandingaccounting.org/asc/340/980/#340-980-25-1)\] should be presented on the balance sheet as an asset and should not be offset against the liability. Contingent recoveries through rates that do not meet the criteria of paragraph 9 \[paragraph [980-340-25-1](https://asc.understandingaccounting.org/asc/340/980/#340-980-25-1)\] should not be recognized either as an asset or as a reduction of the probable liability.
    
    -   FN6 Paragraph 9 of Statement 71 \[paragraph [980-340-25-1](https://asc.understandingaccounting.org/asc/340/980/#340-980-25-1)\] requires a rate-regulated enterprise to capitalize all or part of an incurred cost that would otherwise be charged to expense if it is probable that future revenue will be provided to recover the previously incurred cost from inclusion of the costs in allowable costs for rate-making purposes.
        
-   Question 2: May a rate-regulated enterprise delay recognition of a probable and estimable liability for environmental costs which it has incurred at the date of the latest balance sheet until the regulator's deliberations have proceeded to a point enabling management to determine whether this cost is likely to be included in allowable costs for rate-making purposes?
    
-   Interpretive Response: No. Statement 5 \[paragraph [450-20-25-2](https://asc.understandingaccounting.org/asc/450/20/#450-20-25-2)\] states that an estimated loss from a loss contingency shall be accrued by a charge to income if it is probable that a liability has been incurred and the amount of the loss can be reasonably estimated. <sup class="ph sup">FN7</sup> The staff believes that actions of a regulator can affect whether an incurred cost is capitalized or expensed pursuant to Statement 71 \[paragraph [980-340-25-1](https://asc.understandingaccounting.org/asc/340/980/#340-980-25-1)\], but the regulator's actions cannot affect the timing of the recognition of the liability.
    
    -   FN7 Registrants also should apply the guidance of SOP 96-1 \[Section 410-30-25\] in determining the appropriate recognition of environmental remediation costs.
