Benchmark guidance

Energy and utility companies operate in highly regulated environments with significant public interest considerations. Commodity price volatility can cause significant fluctuations in both revenue and profitability.

Choosing the right benchmark

Revenue at 0.5–0.75% is typical for regulated energy and utility entities. For upstream oil and gas entities, total assets at 1% may be more appropriate given the capital intensity.

Key audit considerations

Decommissioning and environmental restoration provisions (IAS 37) involve long-term estimates with significant uncertainty.

Impairment of exploration and production assets requires judgment about future commodity prices and reserve estimates.

Revenue from regulated tariffs may involve complex true-up mechanisms.

CSRD and sustainability reporting obligations are particularly significant for energy entities.

Frequently asked questions

What benchmark should I use for energy & utilities audits?
Revenue at 0.5–0.75% is typical for regulated energy and utility entities. For upstream oil and gas entities, total assets at 1% may be more appropriate given the capital intensity.
What are the key materiality considerations for energy & utilities?
Decommissioning and environmental restoration provisions (IAS 37) involve long-term estimates with significant uncertainty. Impairment of exploration and production assets requires judgment about future commodity prices and reserve estimates. Revenue from regulated tariffs may involve complex true-up mechanisms. CSRD and sustainability reporting obligations are particularly significant for energy entities.
How does ISA 320 define materiality?
ISA 320 requires auditors to determine materiality for the financial statements as a whole when establishing the overall audit strategy. The benchmark chosen and the percentage applied depend on the nature of the entity, the needs of financial statement users, and the auditor's professional judgment.
