Issued on 2 March 2026, the Audit Oversight Board revised the Guidelines on Continuing Obligations for Registered Auditors to expand transparency reporting requirements and introduce independent oversight principles. The amendments broaden the scope of mandatory disclosures in annual transparency reports and define 'Major Audit Firms' to increase the number of firms subject to these obligations. Key changes include new requirements for Major Audit Firms to disclose compliance with core principles, quality management structures, IT usage, specialized resources, and sustainability risks.
