APA is reporting financial information for its pipelines under Part 10 of the National Gas Rules and the AER’s Pipeline Information Disclosure Guideline.

Financial information under Part 10 of the National Gas Rules and the AER’s Pipeline Information Disclosure Guideline will be reported from FY25.

APA is reporting financial information for its non-scheme pipelines — that is, pipelines that are not subject to full or light regulation, according to AER’s Financial Reporting Guideline for non-Scheme Pipelines. The financial information for the six months to 30 June 2018 and the years ending 30 June 2019 - 2024 includes Pipeline Financial Statements based on Australian Accounting Standards, the weighted average price for services on each of these pipelines, and the number derived using the AER recovered capital method (RCM).

Interested parties should read APA’s Basis of Preparation together with the completed financial information template that was developed by the AER.

In addition, APA advises in relation to RCM:

1. The assumed initial capital structure is 40% equity and 60% debt. The level of equity will increase in circumstances where there is a shortfall in annual revenue.
2. The return on equity is a commercial return applicable in a workably competitive market. Historically, this return for an established pipeline was in the range of 9-11%, depending on factors such as risk, terms and counterparty.
3. The cost of debt is based on a 10-year rolling average of a market rate applicable for an entity whose business is solely the ownership and operatorship of the particular pipeline.
