💡 Accountant's Note
Rate cases (formal proceedings before the PUC to set new utility rates) involve massive expenditures: regulatory attorneys ($500K–$2M), expert witnesses (cost of service consultants, economists, engineers), commission staff interactions, and hearing preparation. These costs are incurred to obtain authorization for future revenues. Under ASC 980, these costs are deferred as a regulatory asset if it is probable that the rate case will result in new rates and these costs will be recovered. Upon approval of new rates, the deferral is amortized over the rate case period (typically 3–5 years until the next rate case).
Practitioner & Systems Framework
💻 ERP Architecture
Track rate case costs by vendor and category in a project code. The deferral decision requires ongoing assessment of the probability of rate case success. If the rate case is withdrawn or denied without new rates, the deferred costs are immediately written off. Upon rate approval, begin amortization over the new rate period.
⚠️ Audit Flags
Auditors assess the probability of cost recovery — particularly in contested cases where intervenors are challenging cost levels. Costs of lost rate cases should not be deferred. The amortization period must align with the regulatory-approved rate period, not management's preference.
📄 Required Documentation
Rate case filing documents, invoices from legal counsel and consultants, PUC docket number and proceeding status, probability of approval assessment, PUC order approving rates (for amortization commencement), amortization schedule.
