FASB 71 accounting for regulated enterprises, now codified as ASC Topic 980, lets a rate-regulated utility report its finances in a way that mirrors how its regulator actually treats costs and revenues. Instead of expensing every cost when incurred and recognizing every receipt when collected, the utility can defer certain costs on the balance sheet as regulatory assets and park certain over-collections as regulatory liabilities, releasing them into income on the same schedule the regulator uses to set rates. The point is to keep the financial statements aligned with the economic reality of cost-of-service ratemaking, where a regulator controls the price and guarantees recovery of prudent costs.
Who Qualifies to Use the Standard
Not every entity under some form of government oversight gets to apply ASC 980. Section 980-10-15-2 lays out three criteria, and all three must be met.
- Rates for the regulated service must be set by, or subject to approval by, an independent third-party regulator or a governing board empowered by statute or contract to bind customers. A company that sets its own prices without regulatory constraint does not qualify.
- Those rates must be designed to recover the entity’s own cost of providing the service, including a reasonable return on investment. This cost-of-service model is what makes the rest of the standard work.
- It must be reasonable to assume rates set at cost-recovery levels can actually be charged to and collected from customers. A utility facing easy customer switching to an unregulated alternative may fail this test even when the first two are met.
The unit of account is flexible. ASC 980 can apply to the entire company, a separable portion such as a specific service territory or customer class, or even a single transaction. A vertically integrated utility might apply the standard to its transmission and distribution business while excluding an unregulated generation subsidiary.
Regulatory Assets
A regulatory asset is a cost that would normally hit the income statement right away but instead sits on the balance sheet because the regulator has signaled it will be recovered through future customer rates. The deferral keeps large, irregular expenses from distorting earnings in a way that would misrepresent the utility’s actual economics.
The threshold is probability. Future recovery must be probable, meaning the collection event is likely to occur based on regulatory precedent, an explicit order, or a well-established pattern of allowing recovery for similar costs. Without that probability, the cost is expensed when incurred.
Storm restoration costs are a familiar example. A hurricane or ice storm can produce a repair bill many times the size of normal quarterly expenses. If the regulator permits rate recovery over a future period, the utility defers the cost as a regulatory asset and amortizes it into expense on the same schedule it collects the matching revenue 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, where actual fuel costs exceeded what the fuel adjustment clause brought in, work the same way: the shortfall is deferred pending the next true-up. Abandoned plant costs follow the same logic when the regulator allows the unamortized investment to be collected over a future period rather than written off as a loss.
Disallowance and Impairment
Regulatory assets live and die by the regulator’s willingness to allow recovery. If recovery of all or part of a deferred amount is later disallowed, the disallowed portion is charged to 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 Utilities also have to watch for impairment on long-lived plant. When an impairment loss is recognized, the next question is whether the loss itself can be recovered through future rates. If the regulator approves recovery, the present value of the expected future rate revenue is set up as a new regulatory asset and amortized over the approved recovery period.
Regulatory Liabilities
Regulatory liabilities are the mirror image: amounts collected from customers but not yet earned, or cost reductions the regulator requires to be passed back through future rate decreases or refunds.
Fuel and purchased-power over-recoveries are the clearest example. When rates collect more than actual fuel costs, the excess is recorded as a liability to be returned in a later adjustment.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 orders shared with ratepayers follow the same pattern. If it is later determined that an amount recorded as a regulatory liability will not be returned to customers, that amount is 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 industry’s largest regulatory liabilities. When the federal corporate rate dropped from 35 percent to 21 percent, utilities that had built accumulated deferred tax reserves at the higher rate suddenly held far more than needed. These excess deferred income taxes, known as EDIT, must be returned to customers.
For the portion of EDIT tied to accelerated depreciation on utility plant, the so-called protected amounts, federal law requires the utility to amortize the excess back to ratepayers no faster than the average rate assumption method, or 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 remain on the balance sheet as regulatory liabilities until fully amortized.
Allowance for Funds Used During Construction
Regulated utilities build expensive, long-lived infrastructure, and construction stretches over years. During that time, capital is tied up earning no return until the asset enters service and goes into rate base. The allowance for funds used during construction, or AFUDC, addresses that gap.
Under ASC 980-835, a utility capitalizes AFUDC when its regulator provides for recovery of financing costs through future rates. What sets AFUDC apart from the interest capitalization rules that apply to unregulated companies is that AFUDC includes a component for equity funds in addition to borrowed funds. When capitalized, the equity component is recorded as a corresponding increase in pre-tax income, reflecting that equity investors are earning a return on capital committed to the project before the plant produces revenue.
AFUDC capitalization is permitted only during active construction and only when future rate recovery is probable. If that probability is lost, the utility stops capitalizing. It cannot then fall back on the general interest capitalization rules in ASC 835-20 as a substitute; if AFUDC fails the probability test, no financing cost gets capitalized at all. When a plant disallowance becomes reasonably possible, AFUDC accrual should stop on the portion of costs within the range of possible disallowance.
Income Tax Normalization
Utility tax accounting sits at the intersection of ratemaking and federal tax law, and it is one of the most technically demanding areas of the standard. The core issue 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 Normalization means the utility cannot flow the immediate tax savings from accelerated depreciation straight through to customers in the current period. The tax expense used in setting rates must be computed using the depreciation method and period used for ratemaking books, and the difference between actual tax paid and tax expense in rates is held in a deferred tax reserve. The consistency requirement extends to projections: estimates of tax expense used for ratemaking must be matched by consistent estimates of depreciation expense, the deferred tax reserve, and rate base. A regulator order forcing a utility to flow through the immediate tax benefit of accelerated depreciation would create a normalization violation and cost the utility its right to use accelerated depreciation at all.
Where normalization is not required and the regulator does flow tax benefits through to customers, the utility recognizes the difference between tax expense in rates and actual tax payable as a regulatory asset or liability, depending on direction. Those regulatory items then create their own secondary tax effect. The regulatory asset or liability is itself a temporary difference requiring deferred tax recognition, because the future revenue needed to recover a regulatory asset will itself be taxable. This gross-up calculation is where utility tax accounting earns its reputation for complexity.
Disclosure Requirements
ASC 980 requires specific disclosures so financial statement users can see the regulatory items driving reported results. At a minimum, a regulated entity must disclose:
- Any regulatory asset for which cost recovery is provided without a return during the recovery period, along with the remaining recovery period.
- The terms of any phase-in plan ordered by a regulator, the amounts deferred for ratemaking purposes, and changes in those deferred amounts.
- Differences between the allowance for earnings on shareholders’ investment capitalized for ratemaking and the amount recognized for financial reporting.
- The regulatory treatment of other post-employment benefit costs, including any amounts deferred as a regulatory asset and the expected recovery period.
- The material income statement effect of refunds recognized in a period different from when the related revenue was earned, including the years in which the original revenue was recognized.
These disclosures matter because regulatory assets and liabilities often represent very large balance sheet items with no physical counterpart. Investors need to see the recovery timelines, the regulatory approvals supporting them, and the risk that some portion might not be collected.
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 move away from cost-of-service ratemaking, or a competitive shift that undermines guaranteed recovery can all trigger discontinuation.
The consequences are immediate. Under ASC 980-20-40-2, the entity must eliminate from its balance sheet the effects of all regulatory actions recognized as assets and liabilities under ASC 980 that would not have been recognized by an unregulated entity. Every regulatory asset gets tested for recoverability under the new conditions; if future recovery is no longer probable, it is written off as a loss. Regulatory liabilities are derecognized, typically as income. The net adjustment flows through income in the period of discontinuance. Finding every regulatory item is harder than it sounds, since some are embedded in other balance sheet accounts or labeled as deferred credits rather than tagged as regulatory items. A thorough inventory is one of the first steps.
Stranded Costs and Securitization
When deregulation forces write-offs of regulatory assets, the resulting losses can threaten financial stability. These stranded costs are investments that were prudent when made under the regulated model but cannot be recovered at competitive market prices. Several states have addressed the problem through securitization, letting utilities issue ratepayer-backed bonds, often called transition bonds or rate reduction bonds, to recover stranded costs over time. The bonds are secured by non-bypassable charges on customer bills and backed by a state legislative pledge not to impair the collection mechanism. Securitization does not eliminate the cost for ratepayers, but it converts an uncertain regulatory asset into a defined payment stream at a lower financing cost than the utility’s normal capital structure would produce.
Continued Oversight After Discontinuation
An entity that stops meeting the ASC 980 criteria may still face some regulatory oversight. In that case the utility has to evaluate the regulator’s intentions to decide whether any existing regulatory assets or liabilities retain economic substance under general GAAP. A binding regulator order requiring a specific refund to customers, for example, may create a genuine liability regardless of whether ASC 980 still applies. Discontinuation is a judgment exercise, not a mechanical sweep of every balance that happens to carry a regulatory label.
