Regulatory Asset - Amortization Over Authorized Recovery Period

Recording the systematic amortization of a regulatory asset into expense as recovery is achieved through customer rates, over the period authorized by the public utility commission.

💡 Accountant's Note

Once the PUC authorizes recovery of a deferred cost over a specified period (e.g., 10 years), the regulatory asset is amortized into expense at the authorized rate ($48.5M / 10 years = $4.85M/year). Simultaneously, the utility is collecting these costs from customers through rates — the revenue from customers covers the amortization expense, resulting in net zero income impact. This symmetry is the entire logic of rate-regulated accounting: costs are matched to the revenues that recover them.

Practitioner & Systems Framework

💻 ERP Architecture

Configure amortization schedules in the regulatory asset sub-ledger linked to the specific rate case order authorizing recovery. If the PUC subsequently changes the recovery period (e.g., accelerates or extends), the amortization schedule must be updated prospectively. Track the regulatory asset balance against the authorized recovery schedule to identify any over/under-recovery positions.

⚠️ Audit Flags

Auditors verify the amortization rate matches the PUC-authorized recovery period. Accelerating amortization beyond the authorized rate may be improper (over-expensing); slowing it below the authorized rate understates expense. If the utility is under-collecting from customers (rates not yet updated), the revenue match may not exist — assess continued deferral appropriateness.

📄 Required Documentation
