Developed in conjunction with CPA Canada, this guide aims to help professional accountants in practice, especially those operating in small- and medium-sized practices (SMPs), in conducting review engagements in compliance with International Standard on Review Engagements (ISRE) 2400 (Revised), Engagements to Review Historical Financial Statements. 

This guidance was written for all organizations, regardless of their size or structure, private or public, to support the accountancy profession’s facilitation of sustainable organizations, financial markets, and economies by providing guiding principles to manage the complexities of performing a robust project and investment appraisal. Greater rigor in the appraisal and decision process can be achieved by using the principles as a benchmark against which to assess an organization’s current practice.

A strong and well-governed professional accountancy organization (PAO) produces and sustains a strong accountancy profession that is able to serve the public interest and contribute to economic stability and growth. A successful PAO gains much of its strength from the sense of identity, benefits, and rights that members derive from membership; and from the contributions that individual members and firms make to the PAO in recognition of its public interest perspective.

This third edition of the guide features enhancements to the two sample manuals, as well as other refinements for clarity and consistency with International Standard on Quality Control (ISQC) 1. The guide contains the requirements set out in ISQC 1 in addition to implementation guidance, including discussion material and an integrated case study that can be used as the basis for education and training.

This FAQ focuses on the relevance of International Standard on Sustainability Assurance (ISSA) 5000 to assurance on sustainability reports to be issued in the European Union. It provides a high-level understanding of how ISSA 5000 can support consistent, high-quality sustainability assurance engagements in the EU—enhancing users’ confidence in sustainability information prepared in accordance with the European Sustainability Reporting Standards (ESRS).
