FASB 71 accounting for regulated enterprises, now codified as ASC Topic 980, lets rate-regulated utilities defer costs on the balance sheet as regulatory assets when a regulator has signaled recovery through future customer rates, and defer amounts collected ahead of the underlying costs as regulatory liabilities. The point is to make the income statement track the regulator’s approved recovery timing rather than the ordinary GAAP rule of recognizing costs and revenues when they occur. That single mechanism drives almost everything else in the standard.
Who Qualifies for This Accounting
Government oversight is not enough on its own. ASC 980-10-15-2 requires all three of the following before an entity, or a portion of one, can apply the standard.
- Rates for the regulated services are set by, or subject to approval by, an independent third-party regulator, or by the entity’s own governing board acting under statute or contract with authority to bind customers.
- Those rates are designed to recover the entity’s own cost of providing the regulated service, including a reasonable return on investment.
- It is reasonable to assume the cost-based rates can actually be charged to and collected from customers, given demand and competition.
The unit of account is flexible. A vertically integrated utility might apply ASC 980 to its transmission and distribution business but not to an unregulated generation subsidiary. A single service territory, customer class, or even a single transaction can qualify if the three criteria are satisfied at that level.
Regulatory Assets
A regulatory asset is a cost the utility would ordinarily expense when incurred but instead parks on the balance sheet because the regulator has indicated it will be recovered through future rates. Deferral keeps large, lumpy expenses from distorting the income statement in ways that would misrepresent the regulated economics.
The recognition threshold is probability. Future recovery must be probable, supported by regulatory precedent, an explicit order, or a well-established pattern of allowing recovery for similar costs. Without that support, the cost hits earnings when incurred.
Storm restoration is the textbook example. When a hurricane or ice storm damages infrastructure, the repair bill can dwarf a normal quarter’s operating expense. If the regulator permits rate recovery over a future period, the utility records the costs as a regulatory asset in FERC Account 182.3 and amortizes them into expense over the same period they are collected in rates.1eCFR. 18 CFR Part 101 – Uniform System of Accounts Prescribed for Public Utilities and Licensees Subject to the Provisions of the Federal Power Act Fuel and purchased-power under-recoveries work the same way: when actual fuel cost exceeds what the fuel adjustment clause collected, the shortfall sits as a regulatory asset until the next true-up. Abandoned plant costs follow the same logic when the regulator allows recovery of the unamortized investment.
Disallowance and Impairment
These balances are not safe from write-down. If rate recovery of all or part of a deferred amount is later disallowed by the regulator, the disallowed portion is charged against income in the year of the disallowance.1eCFR. 18 CFR Part 101 – Uniform System of Accounts Prescribed for Public Utilities and Licensees Subject to the Provisions of the Federal Power Act That risk is the defining feature of a regulatory asset: its value depends on the regulator’s continuing willingness to allow recovery.
Plant assets carry a separate impairment analysis. Cost overruns, demand loss, adverse regulatory change, or a history of operating losses can all indicate the carrying value may not be recoverable. When plant impairment is recognized, the utility then evaluates whether the loss itself can be recovered through future rates. If the regulator approves recovery, the present value of the expected future rate revenue becomes a new regulatory asset, amortized over the approved recovery period.
Regulatory Liabilities
Regulatory liabilities are the mirror image. They represent amounts collected from customers but not yet earned, or cost reductions the regulator requires to be passed back to customers.
Fuel and purchased-power over-recoveries illustrate the basic pattern. When the amount collected through rates exceeds actual fuel costs, the excess is recorded in FERC Account 254 as a liability to be returned through subsequent rate adjustments.1eCFR. 18 CFR Part 101 – Uniform System of Accounts Prescribed for Public Utilities and Licensees Subject to the Provisions of the Federal Power Act Gains on utility property sales that the regulator requires to be shared with ratepayers follow the same treatment. If it is later determined that the amounts will not be returned through rates or refunds, they are recognized as income in the year of the determination.2eCFR. 18 CFR 367.2540 – Account 254, Other Regulatory Liabilities
Excess Deferred Income Taxes After the TCJA
The Tax Cuts and Jobs Act of 2017 created one of the largest regulatory liabilities in industry history. When the federal corporate rate dropped from 35 percent to 21 percent, utilities that had been collecting rates based on the higher rate suddenly held accumulated deferred income tax reserves far larger than needed. The excess, known as EDIT, must be returned to customers.
For the portion tied to accelerated depreciation on utility plant, the “protected” amount, federal law requires amortization back to ratepayers no faster than the average rate assumption method (ARAM) prescribed in the tax code. Returning protected EDIT more rapidly than ARAM is a normalization violation.3Office of the Law Revision Counsel. 26 USC 168 – Accelerated Cost Recovery System Unprotected EDIT, relating to items other than accelerated depreciation, can be returned on whatever schedule the regulator approves. Both categories sit as regulatory liabilities until fully amortized.
Allowance for Funds Used During Construction
Utilities build expensive, long-lived infrastructure, and construction can stretch for years. During that time, capital is committed but no return flows until the asset enters service and is included in the rate base. The allowance for funds used during construction (AFUDC) closes that gap.
Under ASC 980-835, a utility must capitalize AFUDC if its regulator provides for recovery of the financing costs through future rates. The key difference from the interest capitalization rules that apply to unregulated companies is that AFUDC includes an equity component in addition to borrowed funds. When capitalized, that equity component flows through as a corresponding increase in pre-tax income, reflecting that equity investors are receiving a return on capital committed to the project before the plant generates revenue.
Capitalization is permitted only during active construction and only when future rate recovery is probable. If probability of recovery is lost, capitalization stops, and the utility cannot fall back on the general interest capitalization rules in ASC 835-20 as a substitute. If a plant disallowance becomes reasonably possible, the utility should stop accruing AFUDC on the portion of costs within the range of possible disallowance.
Income Tax Normalization
The intersection of rate regulation and income tax accounting produces some of the most technically demanding work in the utility sector. The core problem is timing: utilities often receive tax deductions such as accelerated depreciation years before the related costs are recovered in customer rates.
Section 168(f)(2) of the Internal Revenue Code bars public utility property from using the accelerated cost recovery system unless the utility follows a normalization method of accounting.3Office of the Law Revision Counsel. 26 USC 168 – Accelerated Cost Recovery System In plain terms, the utility cannot pass the immediate tax savings from accelerated depreciation directly to customers in the current period. The tax expense used in setting rates must be calculated using the same depreciation method and period used for ratemaking books, and the gap between actual tax paid and tax expense reflected in rates goes into a reserve for deferred taxes.
Consistency runs through the estimates too. If a utility uses estimates of tax expense for ratemaking, it must use consistent estimates for depreciation expense, the deferred tax reserve, and the rate base. A regulator that ordered flow-through of the immediate accelerated depreciation benefit would trigger a normalization violation, and the utility would lose its right to use accelerated depreciation entirely.
When Flow-Through Is Permitted: The Gross-Up
For tax items where the IRC does not require normalization, a regulator may allow the current tax effect to flow through to customers. When that happens, the utility recognizes the difference between the tax expense in rates and the actual tax payable as a regulatory asset or liability, depending on direction, if it is probable the future tax effect will be recovered from or returned to customers.
The regulatory item then generates its own tax effect. The regulatory asset or liability is itself a temporary difference and requires its own deferred tax recognition. That “gross-up” means establishing a regulatory asset for a flowed-through tax benefit triggers an additional deferred tax liability, because the future revenue needed to recover the regulatory asset will itself be taxable. Getting the circular calculation right is where utility tax accounting earns its reputation.
Required Disclosures
ASC 980 imposes specific disclosures so financial statement users can see what the regulatory balances are and how firmly they are supported. At a minimum, a regulated entity discloses:
- Regulatory assets on which no return is earned during the recovery period, along with the remaining recovery period.
- The terms of any regulator-ordered rate phase-in plan, amounts deferred for ratemaking purposes, and changes in those deferred amounts.
- The nature and amounts of any allowance for earnings on shareholders’ investment that is capitalized for ratemaking but not for financial reporting.
- The regulatory treatment of other post-employment benefit (OPEB) costs, including amounts deferred as a regulatory asset and the expected recovery period.
- The effect of refunds recognized in a period different from the one in which the related revenue was earned, if material to net income, and the years in which the original revenue was recognized.
When ASC 980 Stops Applying
The specialized accounting must stop when an entity, or a separable portion of its operations, no longer meets the three qualifying criteria. Deregulation, a shift away from cost-of-service ratemaking, or a surge in competition that undermines guaranteed cost recovery can all force discontinuation.
Under ASC 980-20-40-2, the entity eliminates from its balance sheet the effects of all regulatory actions that had been recognized as assets and liabilities under ASC 980 but would not have been recognized by an unregulated entity. Every regulatory asset gets tested for recoverability under the new market conditions; if recovery is no longer probable, the asset is written off. Regulatory liabilities are derecognized, typically as income. The net effect flows through earnings in the period of discontinuance.
Finding every item that needs to come off is harder than it sounds. Some regulatory balances sit inside other accounts or carry a “deferred credit” label rather than an explicit regulatory tag. A thorough inventory is one of the first steps.
Stranded Costs and Securitization
Discontinuation write-offs can threaten a utility’s financial stability. Stranded costs are investments that were prudent under the regulated model but cannot be recovered at competitive market prices. Several states have addressed the problem through securitization, allowing utilities to issue ratepayer-backed bonds secured by non-bypassable charges on customer bills, backed by a state legislative pledge not to impair the collection mechanism. The utility receives cash upfront to retire the stranded investment, and the bonds are repaid over a defined period through the dedicated charge, at a financing cost lower than the utility’s ordinary capital structure would produce.
Continued Regulation After Discontinuation
An entity that stops meeting the ASC 980 criteria may still be subject to some form of oversight. In that case, the utility evaluates the regulator’s intentions to see whether particular regulatory assets or liabilities retain economic substance under general GAAP. A binding regulator order requiring refunds of specific amounts, for example, can create a real liability regardless of whether ASC 980 still applies broadly. The analysis calls for judgment, not a mechanical sweep of every balance labeled “regulatory.”
