The Minister of Energy has granted approval for electricity distribution companies to apply to the Board for recovery of Regulatory Assets, effective March 1, 2004. The filing guidelines provide direction for the distributors in filing for these rate changes.
On February 5, 2004, the Board published notice of applications by 92 distribution utilities seeking to recover Regulatory Assets.
The Board has prepared a summary report of Regulatory Asset accounts as provided by the utility in its rate application. The individual application should be referred to for the amount proposed by the utility to be recovered in rates starting April 1, 2004. While every effort is made to ensure accuracy, intervening parties should consult applications of interest.
The Board has determined that the Review of Regulatory Assets for Ontario Electricity Distributors would be done in two Phases, Phase 1 was the granting of interim rate recovery on April 1, 2004. Phase 2 is the prudency review of the Regulatory Asset balances. As a first step in Phase 2, the Board reviewed the Regulatory Asset applications of Hydro One, Toronto Hydro, Enersource Hydro Mississauga and London Hydro. In addition to the decisions on the rate recovery amounts for each of these four distributors, the Board also assessed what would constitute the best evidence, forum and process to determine the reasonableness of Regulatory Asset amounts for the remaining distributors.

Accounting Procedures Handbook - Guidance
From time to time the OEB issues accounting guidance that addresses various matters associated with the APH. To date, this guidance has been labeled as Frequently Asked Questions. As of March 2015, this guidance has been renamed as simply “Guidance” as it may contain clarifications of accounting matters that may arise from other sources other than frequently asked questions.
In addition, the OEB has posted a separate document that contains a list of generic accounts that have been opened since the last update of the APH (pdf) (issued December 2011). This document will be updated at regulator intervals upon the establishment of new accounts or changes to existing accounts.
