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.

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.

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)).

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).

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.

The computations may need to be changed to reflect the economic effects of different fact situations. ##### [360-980-55-3](https://asc.understandingaccounting.org/asc/360/980/#360-980-55-3) Pending content: no Source downloaded (UTC): 2026-09-10T00:13:17.858Z to 2026-09-10T00:13:17.858Z Record version: sha256:1a6997d4476cc68ba0cf5f56e319353526f1ac4e821905cf0e611e7a0c7b51f1 Snapshot version: sha256:15aea8165dff9f5ae47d9484f8470588b13b307f56e1d50801bf4d85ec190e3f Effective as of: not established by retrieval timestamps. The principal assumptions on which the Example is based are as follows: 1. a Upon initial application of Subtopic 740-10, an entity that 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 will adjust its deferred income tax liabilities as required. This Example is presented as though the entity has already applied Subtopic 740-10 prior to the date of the abandonment. If an entity initially applies that Subtopic after a loss has been recognized on an abandonment and before the end of the recovery period for any recoverable costs, the amount of the previously recognized loss may change. The amount of that loss will change if the tax rate used in the initial net-of-tax discount rate under that Subtopic is different from that used by the entity previously. Once that Subtopic is initially applied, the accounting for the abandonment should follow the approach described in this Example. 2. b This Example assumes a tax rate of 34 percent. 3. c Utility A decides to abandon a plant that has been under construction for some time. Although the possibility of abandoning the plant has been under consideration, abandonment was not considered probable before the actual decision was made. 4. d Immediately before the abandonment, the recorded assets for the plant and related deferred income tax liabilities are as follows. - ![ ](https://asc.understandingaccounting.org/asc-img/GUID-493F234E-01C9-469C-B94B-6CDFC7FDA583-low.gif) Assets Deferred Income Tax Liabilities Recorded plant and related deferred income tax liabilities " $750,500,000 " " $85,170,000 " Asset representing revenue that will be provided for payment of income taxes and related deferred income tax liabilities " 76,015,152 " " 25,845,152 " Total " $826,515,152 " " $111,015,152 " 5. e For income tax purposes, the abandoned plant has a basis of $500 million at the date of the abandonment. 6. f Utility A will deduct the remaining tax basis of the abandoned plant ($500,000,000) as an abandonment loss on its income tax return in the year of the abandonment and will receive a tax benefit of 34 percent of the tax basis of the plant ($170,000,000). Utility A operates in a state that has no state income taxes. The federal income tax rate is 34 percent. 7. g Accounting pretax income before the loss on the abandonment and taxable income before any deduction for the loss on the abandonment are both $1,500,000,000. Utility A has no other temporary differences or tax credits. 8. h Utility A operates solely in a single-state jurisdiction. 9. i In the past, Utility A's regulator has permitted recovery of amounts prudently invested in abandoned plants over an extended period of time without a return on unrecovered investment during the recovery period. 10. j The normal practice of Utility A's regulator is to allocate deferred income taxes to assets on which return on investment is disallowed. Deferred taxes allocated to assets excluded from the rate base are not deducted from the rate base for purposes of computing allowable return on investment. 11. k Utility A's regulator normally treats income taxes that were not previously provided 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.") if they result from recovery of other allowable costs. 12. l Utility A's incremental borrowing rate at the date of the decision to abandon the plant is 14 percent, interest payable monthly. 13. m Utility A believes that it is probable that recovery of cost without return on investment during the recovery period will be granted over a period that will not be less than 5 years nor more than 10 years, but it has no basis for estimating the exact time period that the regulator will select. 14. n At the date of the abandonment, Utility A believes that it will take approximately 18 months to obtain a rate order covering the abandoned plant. 15. o No disallowance of recorded cost is expected. 16. p A rate order covering the abandoned plant is received in the 18th month following the abandonment. There is no disallowance of recorded costs of the abandoned plant. Those recorded costs are to be recovered over 60 months commencing in the 19th month after abandonment. ##### [360-980-55-4](https://asc.understandingaccounting.org/asc/360/980/#360-980-55-4) Pending content: no Source downloaded (UTC): 2026-09-10T00:13:17.858Z to 2026-09-10T00:13:17.858Z Record version: sha256:11b23182552ef58c14312ead40bc2dc9b0e9a84db94e16e983af11624495a855 Snapshot version: sha256:15aea8165dff9f5ae47d9484f8470588b13b307f56e1d50801bf4d85ec190e3f Effective as of: not established by retrieval timestamps. Because the amount of deferred taxes related to the remaining investment is both a component of the net investment on which return would be based in the regulatory process and based on the amount of the accounting loss on the abandonment (which is based on the present value of the net investment), the present value of the net investment cannot be derived through a simple present value calculation using a pretax rate. That present value could be derived through a series of iterative calculations, starting with an assumed loss and the resulting deferred tax amounts, then computing the accrual of return on investment and amortization by applying the pretax rate to the resulting net investment, and then computing the income tax effects of the resulting pretax income. Using the remaining asset at the end of the recovery period, the estimate of the loss could be refined until the accrual of a return, amortization, recovery of recorded costs, and the related tax effects resulted in a zero net asset at the end of the recovery period. Alternatively, the net loss can be initially computed based on a present value calculation using an after-tax rate. While that approach is used in this Example, either approach will provide the same result. The following paragraphs illustrate how that approach can be used and the resulting computations of loss recognition, return to be accrued, and amortization. ##### [360-980-55-5](https://asc.understandingaccounting.org/asc/360/980/#360-980-55-5) Pending content: no Source downloaded (UTC): 2026-09-10T00:13:17.858Z to 2026-09-10T00:13:17.858Z Record version: sha256:0216b0b8466f75dfe3330367141b6d39a728ec9d66b21937103e95d3daff0632 Snapshot version: sha256:15aea8165dff9f5ae47d9484f8470588b13b307f56e1d50801bf4d85ec190e3f Effective as of: not established by retrieval timestamps. When the abandonment becomes probable (in this case, at the date of the decision to abandon), Utility A should remove the recorded cost of the plant from the construction work-in-process accounts. Any disallowance of the recorded cost that is probable and can be reasonably estimated should also be recorded as a loss. There is none in this Example. Utility A should record a separate new asset, representing the future revenues expected to result from the regulator's treatment of the cost of the abandoned plant, at the present value of those expected future revenues. ##### [360-980-55-6](https://asc.understandingaccounting.org/asc/360/980/#360-980-55-6) Pending content: no Source downloaded (UTC): 2026-09-10T00:13:17.858Z to 2026-09-10T00:13:17.858Z Record version: sha256:ac066300a5abf86d1b66f107e29323199b72b97cd512142c1e36bb46320f5945 Snapshot version: sha256:15aea8165dff9f5ae47d9484f8470588b13b307f56e1d50801bf4d85ec190e3f Effective as of: not established by retrieval timestamps. The next step is to compute the deferred income tax liabilities that would be recorded if the tax consequences of the abandonment were recognized before any loss related to the disallowance of return on investment were recognized. When the tax basis of the abandoned plant is deducted as an abandonment loss on the current year's tax return, an additional $500,000,000 of the recorded cost of the asset will be without tax basis. Recovery of that additional amount will result in $500,000,000 of taxable income. The deferred income tax liability on that amount should be computed in accordance with Subtopic 740-10. This Example assumes that the rate is the statutory rate of 34 percent and that Utility A should recognize additional deferred income tax liabilities of $170,000,000. ##### [360-980-55-7](https://asc.understandingaccounting.org/asc/360/980/#360-980-55-7) Pending content: no Source downloaded (UTC): 2026-09-10T00:13:17.858Z to 2026-09-10T00:13:17.858Z Record version: sha256:2d6608055543ac104cfb036c93d01648913de588474192660dd1bcff5eef9dc7 Snapshot version: sha256:15aea8165dff9f5ae47d9484f8470588b13b307f56e1d50801bf4d85ec190e3f Effective as of: not established by retrieval timestamps. The amount of tax benefit that resulted from the current deduction of the abandonment loss is also $170,000,000, so no additional asset representing revenue that will be provided for the payment of income taxes should be recognized.

In the event of a change in tax rates, the accumulated deferred income tax liabilities should be adjusted to the computed liability at the new rates. If the change in tax rates causes a reduction of the recorded deferred income tax liability, that reduction would usually result in a reduction of the recorded asset representing revenue that will be provided for payment of income taxes. If the change in tax rates causes an increase of the recorded deferred income tax liability, that increase would usually result in an increase of the recorded asset representing revenue that will be provided for payment of income taxes. However, the regulator's expected rate actions could change that result. ##### [360-980-55-14](https://asc.understandingaccounting.org/asc/360/980/#360-980-55-14) Pending content: no Source downloaded (UTC): 2026-09-10T00:13:17.858Z to 2026-09-10T00:13:17.858Z Record version: sha256:f780b5b1b4b766eb3fe07053e4ab53ccc50b6abb62809ef951ea644f4531cbb1 Snapshot version: sha256:15aea8165dff9f5ae47d9484f8470588b13b307f56e1d50801bf4d85ec190e3f Effective as of: not established by retrieval timestamps.

Assume that Utility B operates in two state jurisdictions. After an extensive prudence investigation, the regulator in one of those state jurisdictions disallows $865 million of the $3.6 billion total cost of Utility B's recently completed nuclear generating plant. That state jurisdiction represents approximately 50 percent of Utility B's operations, and approximately 50 percent of the output of the recently completed plant is expected to be used in that state. The tax basis of the plant is $2.4 billion. The regulator indicates that the tax benefit from a ratable portion of depreciation will be given to the shareholders as a result of the disallowance. After consultation with counsel, Utility B decides that it should not appeal the regulator's disallowance. The regulator in Utility B's other state jurisdiction has not participated in the prudence investigation, and there is no indication that a similar disallowance is likely in that jurisdiction. ##### [360-980-55-17](https://asc.understandingaccounting.org/asc/360/980/#360-980-55-17) Pending content: no Source downloaded (UTC): 2026-09-10T00:13:17.858Z to 2026-09-10T00:13:17.858Z Record version: sha256:a5e7b3849cd8dcf1c9d23d7aee26de356ee4772abf1c5c871b6a851a1aaa7b38 Snapshot version: sha256:15aea8165dff9f5ae47d9484f8470588b13b307f56e1d50801bf4d85ec190e3f Effective as of: not established by retrieval timestamps. Utility B should recognize the effective disallowance as a loss. Because only 50 percent of the plant's cost will be recoverable from customers in the state, the effective disallowance is 50 percent of the amount disallowed, or $432.5 million. The disallowance should be recognized when the disallowance is probable and the amount of the disallowance can be reasonably estimated, and those conditions are met in this case. The tax benefit of the loss will be realized as future depreciation is taken for income tax purposes. Since the tax benefit of the plant is based on $2.4 billion and the cost of the plant prior to the disallowance is $3.6 billion, only two-thirds of the loss is available for tax benefit. A deferred tax benefit, based on two-thirds of the loss, can be recognized when the loss is recognized providing that benefit meets the criteria of Subtopic 740-10 for recognition. ##### [360-980-55-18](https://asc.understandingaccounting.org/asc/360/980/#360-980-55-18) Pending content: no Source downloaded (UTC): 2026-09-10T00:13:17.858Z to 2026-09-10T00:13:17.858Z Record version: sha256:41b88ca2af7ce21eca1637024fdfec8a9b4483757c34b80b4e53671c12817af5 Snapshot version: sha256:15aea8165dff9f5ae47d9484f8470588b13b307f56e1d50801bf4d85ec190e3f Effective as of: not established by retrieval timestamps.

To avoid the cost and time delay that would be involved in a full-scale prudence investigation of the construction of the plant, Utility C and its regulator agree that the total cost of the plant that will be allowable in determining depreciation and that will be allowed in Utility C's rate base will be $3.4 billion. If the eventual cost of the plant exceeds that cap, a ratable portion of the tax benefit of depreciation will accrue to the benefit of the shareholders. For tax purposes, the plant is expected to have a net depreciable basis of $2.0 billion. ##### [360-980-55-23](https://asc.understandingaccounting.org/asc/360/980/#360-980-55-23) Pending content: no Source downloaded (UTC): 2026-09-10T00:13:17.858Z to 2026-09-10T00:13:17.858Z Record version: sha256:2768e9effefbe2333edda1d07d0a76cd9b0d3ff624d4de07f6386eefe8f734ff Snapshot version: sha256:15aea8165dff9f5ae47d9484f8470588b13b307f56e1d50801bf4d85ec190e3f Effective as of: not established by retrieval timestamps.

If the regulator ordered a cost cap that Utility C did not agree to, Utility C would have to assess whether the criteria of Topic 450 for loss recognition are met. If those criteria are met, the accounting would be as indicated above. Otherwise, no loss would be recognized until that loss was probable and could be reasonably estimated. Because of the possible disallowance inherent in the cost cap, it may no longer be probable that some amount of allowance for funds used during construction will be included in allowable costs in the future, and that amount may be reasonably estimable. In that case, that amount of allowance for funds used during construction would not be capitalized. ##### [360-980-55-26](https://asc.understandingaccounting.org/asc/360/980/#360-980-55-26) Pending content: no Source downloaded (UTC): 2026-09-10T00:13:17.858Z to 2026-09-10T00:13:17.858Z Record version: sha256:560776ba34fe97ec481c62962ea5f32448026119050ab08530a37e0bdba53a94 Snapshot version: sha256:15aea8165dff9f5ae47d9484f8470588b13b307f56e1d50801bf4d85ec190e3f Effective as of: not established by retrieval timestamps.

Assume that Utility D operates solely in a single-state jurisdiction. On January 1, 19X1, Utility D's new electric generating plant becomes operational.

Utility D's regulator concludes that part of the cost of the recently completed plant was imprudently incurred. However, rather than disallow the specific costs that were imprudent, the regulator instead excludes 10 percent ($100 million) of the plant from the rate base, thereby providing no return on investment on that portion of the plant. The regulator does not intend any part of the tax benefit of depreciation to accrue to the benefit of Utility D's shareholders. The regulator indicates that the exclusion of 10 percent of the plant's cost from the rate base is intended to be permanent. The utility concludes that it will not appeal the disallowance after considering the likely outcome of an appeal. ##### [360-980-55-29](https://asc.understandingaccounting.org/asc/360/980/#360-980-55-29) Pending content: no Source downloaded (UTC): 2026-09-10T00:13:17.858Z to 2026-09-10T00:13:17.858Z Record version: sha256:7fc2cf68d1a270c469938c37b83d92a4727e2860fef1231570b7fd96238421fa Snapshot version: sha256:15aea8165dff9f5ae47d9484f8470588b13b307f56e1d50801bf4d85ec190e3f Effective as of: not established by retrieval timestamps. Utility D should record the indirect disallowance as a loss and should estimate the amount of that loss using the best available information. If the regulator specifies the amount of cost that was imprudent, that amount may be the best estimate of the loss. Otherwise, Utility D would have to estimate the future cash flows that have been disallowed as a result of the order and determine the effective disallowance by computing the present value of those disallowed future cash flows. Since both the disallowed future cash flows and the appropriate discount rate to compute the present value would be estimates, those estimates should be calculated on a consistent basis. Accordingly, if the future cash flows are estimated based on the current weighted-average overall cost of Utility D's capital, that weighted-average overall cost of capital should also be used as the discount rate. The loss has no tax benefit to Utility D. ##### [360-980-55-30](https://asc.understandingaccounting.org/asc/360/980/#360-980-55-30) Pending content: no Source downloaded (UTC): 2026-09-10T00:13:17.858Z to 2026-09-10T00:13:17.858Z Record version: sha256:892d2c85e5ebcac5666e082d3b1d133675905ce07e646d6f55fe28d0920df864 Snapshot version: sha256:15aea8165dff9f5ae47d9484f8470588b13b307f56e1d50801bf4d85ec190e3f Effective as of: not established by retrieval timestamps.

The following is the text of SAB Topic 10.C, Jointly Owned Electric Utility Plants. - Facts: Groups of electric utility companies have been building and operating utility plants under joint ownership agreements or arrangements which do not create legal entities for which separate financial statements are presented. FN1 Under these arrangements, a participating utility has an undivided interest in a utility plant and is responsible for its proportionate share of the costs of construction and operation and its entitled to its proportionate share of the energy produced. - FN1 Before considering the guidance in this SAB Topic, registrants are reminded that the arrangement should be evaluated in accordance with the provisions of Interpretation 46 \[Topic 810\]. - During the construction period a participating utility finances its own share of a utility plant using its own financial resources and not the combined resources of the group. Allowance for funds used during construction is provided in the same manner and at the same rates as for plants constructed to be used entirely by the participant utility. - When a joint-owned plant becomes operational, one of the participant utilities acts as operator and bills the other participants for their proportionate share of the direct expenses incurred. Each individual participant incurs other expenses related to transmission, distribution, supervision and control which cannot be related to the energy generated or received from any particular source. Many companies maintain depreciation records on a composite basis for each class of property so that neither the accumulated allowance for depreciation nor the periodic expense can be allocated to specific generating units whether jointly or wholly owned. - Question: What disclosure should be made on the financial statements or in the notes concerning interests in jointly owned utility plants? - Interpretive Response: A participating utility should include information concerning the extent of its interests in jointly owned plants in a note to its financial statements. The note should include a table showing separately for each interest in a jointly owned plant the amount of utility plant in service, the accumulated provision for depreciation (if available), the amount of plant under construction, and the proportionate share. The amounts presented for plant in service or plant under construction may be further subdivided to show amounts applicable to plant subcategories such as production, transmission, and distribution. The note should include statements that the dollar amounts represent the participating utility's share in each joint plant and that each participant must provide its own financing. Information concerning two or more generating plants on the same site may be combined if appropriate. - The note should state that the participating utility's share of direct expenses of the joint plants is included in the corresponding operating expenses on its income statement (e. g., fuel, maintenance of plant, other operating expense). If the share of direct expenses is charged to purchased power then the note should disclose the amount so charged and the proportionate amounts charged to specific operating expenses on the records maintained for the joint plants. ##### [360-980-S99-2](https://asc.understandingaccounting.org/asc/360/980/#360-980-S99-2) Pending content: no Source downloaded (UTC): 2026-09-10T00:13:32.748Z to 2026-09-10T00:13:32.748Z Record version: sha256:8a772361148386c7d8b7fc1845c7ce6c3ca2020dd3669cb1e81930e3ccd3812c Snapshot version: sha256:15aea8165dff9f5ae47d9484f8470588b13b307f56e1d50801bf4d85ec190e3f Effective as of: not established by retrieval timestamps. The following is the text of SAB Topic 10.E, Classification of Charges for Abandonment and Disallowances. - Facts: A public utility company abandons the construction of a plant and, under the provisions of Statement 90 \[Topic 980\], must charge a portion of the costs of the abandoned plant to expense. FN3 Also, the utility determines that it is probable that certain costs of a recently completed plant will be disallowed, and charges those costs to expense as required by Statement 90 \[Topic 980\]. - FN3 Paragraph 3 of Statement 90 \[paragraph [980-360-35-3](https://asc.understandingaccounting.org/asc/360/980/#360-980-35-3)\] requires that costs of abandoned plants in excess of the present value of the future revenues expected to be provided to recover any allowable costs be charged to expense in the period that the abandonment becomes probable. Also, paragraph 7 of Statement 90 \[paragraph [980-360-35-12](https://asc.understandingaccounting.org/asc/360/980/#360-980-35-12)\] requires that disallowed costs for recently completed plants be charged to expense when the disallowance becomes probable and can be reasonably estimated. - Question: May such charges for abandonments and disallowances be reported as extraordinary items in the statement of income? - Interpretive Response: No. The staff does not believe that such charges meet the requirements of APB Opinion 30 \[Topic 225\] that an item be both unusual and infrequent to be classified as an extraordinary item. Accordingly, the public utility was advised by the staff that such charges should be reported as a component of income from continuing operations, separately presented, if material. FN4 - FN4 Additionally, the registrant was reminded that paragraph 26 of APB Opinion 30 \[paragraph [220-20-45-1](https://asc.understandingaccounting.org/asc/220/20/#220-20-45-1)\] provides that items which are not reported as extraordinary should not be reported on the income statement net of income taxes or in any manner that implies that they are similar to extraordinary items. - Paragraph 20 of APB Opinion 30 \[paragraph [225-20-45-2](https://asc.understandingaccounting.org/asc/225/20/#225-20-45-2)\] indicates that to be unusual, an item must "possess a high degree of abnormality and be of a type clearly unrelated to, or only incidentally related to, the ordinary and typical activities of the entity, taking into account the environment in which the entity operates." Similarly, that paragraph indicates that, to be infrequent, an event should "not reasonably be expected to recur in the foreseeable future." - Electric utilities operate under a franchise that requires them to furnish adequate supplies of electricity for their service area. That undertaking requires utilities to continually forecast the future demand for electricity, and the costs to be incurred in constructing the plants necessary to meet that demand. Abandonments and disallowances result from the failure of demand to reach projected levels and/or plant construction costs that exceed anticipated amounts. Neither event qualifies as being both unusual and infrequent in the environment in which electric utilities operate. - Accordingly, the staff believes that charges for abandonments and disallowances under Statement 90 should not be presented as extraordinary items. FN5 - FN5 The staff also notes that paragraphs 3 and 7 of Statement 90 \[paragraphs [980-360-35-3](https://asc.understandingaccounting.org/asc/360/980/#360-980-35-3) and [980-360-35-12](https://asc.understandingaccounting.org/asc/360/980/#360-980-35-12)\], in requiring that such costs be "recognized as a loss," do not specify extraordinary item treatment. The staff believes that it generally has been the FASB's practice to affirmatively require extraordinary item treatment when it believes that it is appropriate for charges or credits to income specifically required by a provision of a statement.
