IASB finalises rate regulation accounting standard

The International Accounting Standards Board (IASB) has published IFRS 20 (Regulatory Assets and Regulatory Liabilities) – a new standard for accounting the financial effects of rate regulation.

IFRS 20 affects companies – such as utilities providers – that are subject to rate regulation determining how much and when they can charge customers.

IASB chair Andreas Barckow stated: “IFRS 20 will provide investors with more complete and transparent information about companies operating in these critical rate-regulated industries.”

The standard replaces IFRS 14 (Regulatory Deferral Accounts) and supplements information provided under IFRS 15 (Revenue from Contracts with Customers). It takes effect for annual reporting periods beginning on or after 1 January 2029.
