allowable costs

This subtopic governs when a rate-regulated entity may capitalize incurred costs as regulatory assets (deferred costs) and, in particular, how to account for phase-in plans — rate-making arrangements that defer part of the rate increase caused by placing a newly completed plant in service in order to avoid a "rate spike." A cost is capitalized only if it is probable that future revenue at least equal to the cost will result from including it in allowable costs and that revenue is intended to recover the previously incurred cost rather than fund similar future costs (980-340-25-1). Amounts deferred under a phase-in plan may be capitalized only for plants completed or substantially constructed before January 1, 1988, and only if the plan meets four strict criteria (980-340-25-3).

This Subtopic explains when a regulator's rate actions create liabilities (regulatory liabilities) for an entity with regulated operations. Three mechanisms create liabilities: required refunds to customers that meet the loss-contingency accrual criteria, current rates collected to recover costs expected to be incurred in the future for which the entity remains accountable, and gains or other reductions of net allowable costs that the regulator requires be amortized to customers over future periods. A regulator's actions can eliminate a liability only if the regulator's actions imposed it in the first place.

This subtopic addresses loss contingencies for entities with regulated operations (rate-regulated utilities). Its core rule: when a regulator allows an entity to recover an amount for a contingency in rates even though the amount does not meet the accrual criteria of 450-20-25-2, and the regulator requires the entity to remain accountable for amounts collected but not yet spent for the intended purpose, the increased charges to customers give rise to a liability rather than income.

This Subtopic addresses compensated absences and other compensation-related costs for entities with regulated operations. Even though a regulator may allow such compensation in rates only when paid, the entity must still accrue the liability under Topic 710 because regulator rate actions cannot eliminate obligations the regulator did not impose. Because the cost will be recoverable in future rates as paid, the entity simultaneously records a regulatory asset representing the probable future increased revenue.

ASC 980-10 sets the overall scope and framework for accounting by entities with rate-regulated operations. Because regulators sometimes allow costs into rates in a period different from when an unregulated entity would expense them, the rate-making process can create assets (regulatory assets), reduce assets, or create liabilities; an incurred cost the regulator permits to be recovered in a future period is accounted for like a cost reimbursable under a cost-reimbursement-type contract (980-10-05-5, 05-6). The Topic applies only to operations meeting the three criteria in 980-10-15-2 and provides incremental industry guidance that overrides conflicting guidance elsewhere in the Codification.
