When it becomes probable (likely to occur) that an operating asset or an asset under construction will be abandoned, the cost of that asset shall be removed from construction work-in-process or plant-in-service. ##### [360-980-35-2](https://asc.understandingaccounting.org/asc/360/980/#360-980-35-2) Pending content: no Source downloaded (UTC): 2026-09-10T00:13:14.576Z to 2026-09-10T00:13:14.576Z Record version: sha256:024652b33b950176e624294658ec28de1851422f250b0b51521a588956ac07df Snapshot version: sha256:15aea8165dff9f5ae47d9484f8470588b13b307f56e1d50801bf4d85ec190e3f Effective as of: not established by retrieval timestamps. The entity shall determine whether recovery of any allowed cost is likely to be provided with either of the following: 1. a Full return on investment during the period from the time when abandonment becomes probable to the time when recovery is completed 2. b Partial or no return on investment during that period. ##### [360-980-35-3](https://asc.understandingaccounting.org/asc/360/980/#360-980-35-3) Pending content: no Source downloaded (UTC): 2026-09-10T00:13:14.576Z to 2026-09-10T00:13:14.576Z Record version: sha256:dfe07b5dac0b2b93699c3a33264e71418b363f103f4220cc63f70a0676f58329 Snapshot version: sha256:15aea8165dff9f5ae47d9484f8470588b13b307f56e1d50801bf4d85ec190e3f Effective as of: not established by retrieval timestamps. That determination shall focus on the facts and circumstances related to the specific abandonment and shall also consider the past practice and current policies of the applicable regulatory jurisdiction on abandonment situations. Based on that determination, the entity shall account for the cost of the abandoned plant as follows: 1. a Full return on investment is likely to be provided. Any disallowance of all or part of the cost of the abandoned plant that is both probable and reasonably estimable (as defined in Topic 450) shall be recognized as a loss, and the carrying basis of the recorded asset shall be correspondingly reduced. The remainder of the cost of the abandoned plant shall be reported as a separate new asset. 2. b Partial or no return on investment is likely to be provided. Any disallowance of all or part of the cost of the abandoned plant that is both probable and reasonably estimable shall be recognized as a loss. The present value of the future revenues expected to be provided to recover the allowable cost of that abandoned plant and return on investment, if any, shall be reported as a separate new asset. Any excess of the remainder of the cost of the abandoned plant over that present value also shall be recognized as a loss. The discount rate used to compute the present value shall be the entity's incremental borrowing rate, that is, the rate that the entity would have to pay to borrow an equivalent amount for a period equal to the expected recovery period. In determining the present value of expected future revenues, the entity shall consider such matters as the following: 1. 1 The probable time period before such recovery is expected to begin 2. 2 The probable time period over which recovery is expected to be provided. If the estimate of either period is a range, the guidance in Section 450-20-55 shall be applied to determine the loss to be recognized. Accordingly, the most likely period within that range shall be used to compute the present value. If no period within that range is a better estimate than any other, the present value shall be based on the minimum time period within that range. ##### [360-980-35-4](https://asc.understandingaccounting.org/asc/360/980/#360-980-35-4) Pending content: no Source downloaded (UTC): 2026-09-10T00:13:14.576Z to 2026-09-10T00:13:14.576Z Record version: sha256:0a45a7b30230c6e3cad081e752d308cb8206e5e822c23d6563ce1a005d9bbfca Snapshot version: sha256:15aea8165dff9f5ae47d9484f8470588b13b307f56e1d50801bf4d85ec190e3f Effective as of: not established by retrieval timestamps. The recorded amount of the new asset shall be adjusted from time to time as necessary if new information indicates that the estimates used to record the separate new asset have changed. The rate order is usually viewed as the confirming event, permitting an estimate of the loss to be refined at that time. However, a loss shall not be recognized unless it is probable that a loss has occurred and the amount can be reasonably estimated. If those criteria are not met at the time of an initial rate order, the loss shall not be recognized at that time. ##### [360-980-35-5](https://asc.understandingaccounting.org/asc/360/980/#360-980-35-5) Pending content: no Source downloaded (UTC): 2026-09-10T00:13:14.576Z to 2026-09-10T00:13:14.576Z Record version: sha256:a4dcd944c46810438721610d6b4c6fe60522795cd9d0a3bfc37150023f6a2bdb Snapshot version: sha256:15aea8165dff9f5ae47d9484f8470588b13b307f56e1d50801bf4d85ec190e3f Effective as of: not established by retrieval timestamps. The estimates used to record the separate new asset include both of the following: 1. a The determination of whether full return on investment will be provided and, if not, the probable time period before recovery is expected to begin and the probable time period over which recovery is expected to be provided 2. b The amount of any probable and reasonably estimable disallowance of recorded costs of the abandoned plant. ##### [360-980-35-6](https://asc.understandingaccounting.org/asc/360/980/#360-980-35-6) Pending content: no Source downloaded (UTC): 2026-09-10T00:13:14.576Z to 2026-09-10T00:13:14.576Z Record version: sha256:ab5aee1b28d6fbba20dc9e31eb797d5f4edc94029ed5fd3952f9388798c7717b Snapshot version: sha256:15aea8165dff9f5ae47d9484f8470588b13b307f56e1d50801bf4d85ec190e3f Effective as of: not established by retrieval timestamps. The amount of the adjustment shall be recognized in income as a loss or gain. The recorded carrying amount of the new asset shall not be adjusted for changes in the entity's incremental borrowing rate. ##### [360-980-35-7](https://asc.understandingaccounting.org/asc/360/980/#360-980-35-7) Pending content: no Source downloaded (UTC): 2026-09-10T00:13:14.576Z to 2026-09-10T00:13:14.576Z Record version: sha256:61d25bbeda9d418bb87399c1c567224c6045a61f2028e3418d940a6ab747800a Snapshot version: sha256:15aea8165dff9f5ae47d9484f8470588b13b307f56e1d50801bf4d85ec190e3f Effective as of: not established by retrieval timestamps. During the period between the date on which the new asset is recognized and the date on which recovery begins, the carrying amount shall be increased by accruing a carrying charge. The rate used to accrue that carrying charge shall be as follows: 1. a If full return on investment is likely to be provided, a rate equal to the allowed overall cost of capital in the jurisdiction in which recovery is expected to be provided shall be used. 2. b If partial or no return on investment is likely to be provided, the rate that was used to compute the present value shall be used. ##### [360-980-35-8](https://asc.understandingaccounting.org/asc/360/980/#360-980-35-8) Pending content: no Source downloaded (UTC): 2026-09-10T00:13:14.576Z to 2026-09-10T00:13:14.576Z Record version: sha256:7310bc765caebc9da122d0c4f121efbfc7187d824c4cd3dc5cc0abfdd4053123 Snapshot version: sha256:15aea8165dff9f5ae47d9484f8470588b13b307f56e1d50801bf4d85ec190e3f Effective as of: not established by retrieval timestamps. During the recovery period, the new asset shall be amortized as follows: 1. a If full return on investment is likely to be provided, the asset shall be amortized in the same manner as that used for rate-making purposes. 2. b If partial or no return on investment is likely to be provided, the asset shall be amortized in a manner that will produce a constant return on the unamortized investment in the new asset equal to the rate at which the expected revenues were discounted. ##### [360-980-35-9](https://asc.understandingaccounting.org/asc/360/980/#360-980-35-9) Pending content: no Source downloaded (UTC): 2026-09-10T00:13:14.576Z to 2026-09-10T00:13:14.576Z Record version: sha256:61ecc5f2de250812a01ef3bd947ade41784fb4d5621be149c7b856c938ca4747 Snapshot version: sha256:15aea8165dff9f5ae47d9484f8470588b13b307f56e1d50801bf4d85ec190e3f Effective as of: not established by retrieval timestamps. Usually, the net loss on an abandonment shall be computed by discounting the after-tax future revenues expected to be allowed by the regulator at an after-tax incremental borrowing rate and comparing the result to the recorded net investment in the abandoned plant. If that discounted present value is less than the recorded net investment, a net loss shall be recognized. However, the present accounting model generally does not permit display of losses on a net-of-tax basis. As a result, the net loss on an abandonment is grossed up for display purposes. ##### [360-980-35-10](https://asc.understandingaccounting.org/asc/360/980/#360-980-35-10) Pending content: no Source downloaded (UTC): 2026-09-10T00:13:14.576Z to 2026-09-10T00:13:14.576Z Record version: sha256:5bdcfcb3928964da3fdbfb309f38eb74c636ded643b1049903249b2f511a53bc Snapshot version: sha256:15aea8165dff9f5ae47d9484f8470588b13b307f56e1d50801bf4d85ec190e3f Effective as of: not established by retrieval timestamps. The computation of a loss on an abandonment (see Example 1 \[paragraph [980-360-55-2](https://asc.understandingaccounting.org/asc/360/980/#360-980-55-2)\]) is intended to approximate the economic effects of the regulator's rate actions in the preceding paragraph. The computation is based on both of the following general assumptions about the rate-making methods used for income taxes: 1. a Deferred income taxes are allocated to the assets that resulted in those deferred income taxes. Under that assumption, if certain assets are included in the rate base (that is, a return is allowed on those assets), the deferred income taxes allocated to those assets are deducted from the rate base in computing the investment on which a return will be allowed. Similarly, if certain assets are excluded from the rate base (that is, a return is not allowed on those assets), the deferred income taxes allocated to those assets are not deducted from the rate base in computing the investment on which a return will be allowed. 2. b Income taxes that result from recovery of the recorded cost of the abandoned plant will be treated as [allowable costs](https://asc.understandingaccounting.org/glossary/a/#allowable-costs "All costs for which revenue is intended to provide recovery. Those costs can be actual or estimated. In that context, allowable costs include interest cost and amounts provided for earnings on shareholders' investments.") when those income taxes become payable to the extent those income taxes do not represent repayment of an income tax benefit that has already accrued to the entity's shareholders. ##### [360-980-35-11](https://asc.understandingaccounting.org/asc/360/980/#360-980-35-11) Pending content: no Source downloaded (UTC): 2026-09-10T00:13:14.576Z to 2026-09-10T00:13:14.576Z Record version: sha256:8a24427b27626070275668d108fcacc712faa854af684a96bf151343be3aad32 Snapshot version: sha256:15aea8165dff9f5ae47d9484f8470588b13b307f56e1d50801bf4d85ec190e3f Effective as of: not established by retrieval timestamps. If the rate-making methods used for an entity differ from the assumptions stated in the preceding paragraph, the computation used to compute the loss on the abandonment shall be different from that described in paragraph [980-360-35-9](https://asc.understandingaccounting.org/asc/360/980/#360-980-35-9) and illustrated in Example 1 (see paragraph [980-360-55-2](https://asc.understandingaccounting.org/asc/360/980/#360-980-55-2)). The computation shall be changed to reflect the different economics of those different rate-making methods. For example, if the regulator deducts all existing deferred income taxes from the rate base in determining the investment on which a return will be provided (instead of allocating deferred income taxes between items included in the rate base and items excluded from the rate base), the procedure effectively disallows a return on the gross investment in the abandoned plant instead of disallowing a return on the net investment, and the recognized loss shall reflect a disallowance of a return on the gross investment in the abandoned plant. #### Cost Disallowances ##### [360-980-35-12](https://asc.understandingaccounting.org/asc/360/980/#360-980-35-12) Pending content: no Source downloaded (UTC): 2026-09-10T00:13:14.576Z to 2026-09-10T00:13:14.576Z Record version: sha256:6f23e42098835c92f9889505f3025a1ff2db2a4db839a9b96ac296db1ee7ed16 Snapshot version: sha256:15aea8165dff9f5ae47d9484f8470588b13b307f56e1d50801bf4d85ec190e3f Effective as of: not established by retrieval timestamps. When it becomes probable that part of the cost of a recently completed plant will be disallowed for rate-making purposes and a reasonable estimate of the amount of the disallowance can be made, the estimated amount of the probable disallowance shall be deducted from the reported cost of the plant and recognized as a loss. Section 450-20-55 provides guidance for making a reasonable estimate of the amount of a loss. If part of the cost is explicitly, but indirectly, disallowed (for example, by an explicit disallowance of return on investment on a portion of the plant), an equivalent amount of cost shall be deducted from the reported cost of the plant and recognized as a loss. ##### [360-980-35-13](https://asc.understandingaccounting.org/asc/360/980/#360-980-35-13) Pending content: no Source downloaded (UTC): 2026-09-10T00:13:14.576Z to 2026-09-10T00:13:14.576Z Record version: sha256:8f08bcb5267b470170656c5e0af6c7fb139abbc22c5da2691a835c6c7f5403ed Snapshot version: sha256:15aea8165dff9f5ae47d9484f8470588b13b307f56e1d50801bf4d85ec190e3f Effective as of: not established by retrieval timestamps. Excess capacity disallowances relate to part of the cost of service of a recently completed plant and are based on a finding that an entity's reserve capacity exceeds an amount deemed to be reasonable. If an excess capacity disallowance is ordered by a regulator without a specific finding that the entity should not have constructed that capacity or should have delayed the construction of that capacity, the rate order raises questions about whether the entity meets the criteria of paragraph [980-10-15-2](https://asc.understandingaccounting.org/asc/980/10/#980-10-15-2) for application of this Topic, in that it is not being regulated based on its own cost of service. However, because such a rate order itself is neither a direct disallowance nor an explicit, but indirect, disallowance of part of the cost of the plant, this Section does not specify the accounting for it. If an excess capacity disallowance is ordered by a regulator with a specific finding that the entity should not have constructed that capacity or should have delayed the construction of that capacity, the rate order may be an explicit, but indirect, disallowance of part of the cost of the plant, and the entity shall account for the substance of that order as set forth in the preceding paragraph. ##### [360-980-35-14](https://asc.understandingaccounting.org/asc/360/980/#360-980-35-14) Pending content: no Source downloaded (UTC): 2026-09-10T00:13:14.576Z to 2026-09-10T00:13:14.576Z Record version: sha256:d5ac0874644525d03e5f02fde8416eb17c3ae809f88a2bb3d408472569953b5e Snapshot version: sha256:15aea8165dff9f5ae47d9484f8470588b13b307f56e1d50801bf4d85ec190e3f Effective as of: not established by retrieval timestamps. If a regulator has included a recently completed plant in rates based on the assumed cost of another plant rather than based on the cost of the plant that exists, then the entity is not being regulated based on its own cost, and the criteria of paragraph [980-10-15-2](https://asc.understandingaccounting.org/asc/980/10/#980-10-15-2) for application of this Topic do not appear to be met. If the rate order is based on a finding that, based on factors that were known during the construction, the entity should not have constructed the plant that it did construct, the order may be an explicit, but indirect, disallowance, and it shall be accounted for as set forth in paragraph [980-360-35-12](https://asc.understandingaccounting.org/asc/360/980/#360-980-35-12). Otherwise, unless the order is being appealed, the entity shall consider discontinuing application of this Topic. ##### [360-980-35-15](https://asc.understandingaccounting.org/asc/360/980/#360-980-35-15) Pending content: no Source downloaded (UTC): 2026-09-10T00:13:14.576Z to 2026-09-10T00:13:14.576Z Record version: sha256:8f5e83b51e822bf0838887e64cd6784cb35dba9ec5f87d1f9da3ff9ba5ab7fb2 Snapshot version: sha256:15aea8165dff9f5ae47d9484f8470588b13b307f56e1d50801bf4d85ec190e3f Effective as of: not established by retrieval timestamps. Regulators have considerable discretion in selecting a rate that represents a fair return on equity investment, and that specific matters included in a settlement agreement might not be apparent. Explicit, but indirect, disallowances shall be reported as disallowances; however, an entity is not required to determine whether the terms of a settlement agreement or rate order contain a hidden, indirect disallowance. ##### [360-980-35-16](https://asc.understandingaccounting.org/asc/360/980/#360-980-35-16) Pending content: no Source downloaded (UTC): 2026-09-10T00:13:14.576Z to 2026-09-10T00:13:14.576Z Record version: sha256:bc6956fdd45b0ec5d4a8e73664eae4eb10049a7390f6ce462af38285ec3bedb9 Snapshot version: sha256:15aea8165dff9f5ae47d9484f8470588b13b307f56e1d50801bf4d85ec190e3f Effective as of: not established by retrieval timestamps.
