The International Auditing and Assurance Standards Board (IAASB) has released narrow scope amendments to its standards revising the definition of listed entity to align with the definition in the International Ethics Standards Board for Accountants’ (IESBA) Code of Ethics for Professional Accountants (including International Independence Standards). The new definition will amend the International Standards on Quality Management and International Standards on Auditing. In addition, amendments to International Standard on Review Engagement 2400 (Revised), Engagements to Review Historical Financial Statements, aim to align with the IESBA Code of Ethics regarding certain public disclosures about the application of independence requirements.

The narrow scope amendments:

• Adopt the same definition of publicly traded entity (PTE) in the ISQMs and ISAs as adopted in the IESBA Code of Ethics, while recognizing the role local standard setters and regulators play in defining PTEs for their jurisdictions.
• Incorporate an overarching objective for differential requirements for PTEs in the ISQMs and ISAs and a framework for when it may be appropriate to apply such requirements to other entities.
• Amend the applicability of the existing requirements for audits of listed entities to apply to audits of PTEs.
• Add a new requirement in ISRE 2400 (Revised) for public disclosure in the practitioner’s review report when the practitioner applied independence requirements specific to reviews of financial statements of certain entities, e.g., for public interest entities.

Throughout the development of these amendments, the IAASB maintained close collaboration and coordination with IESBA, striving to align key concepts in the IAASB’s and IESBA’s standards, to the greatest extent possible.

To assist its stakeholder understanding and implementing the narrow scope amendments, the IAASB has published a Basis for Conclusions, available on its website here.

Effective Date and Resources
The narrow scope amendments become effective for engagements for periods beginning on or after December 15, 2026. This effective date is aligned with the effective dates for the IAASB’s recently revised standards on going concern and fraud, ISA 570 (Revised 2024) and ISA 240 (Revised), respectively. Together, these standards provide a stronger, more coordinated response to the risks of fraud and financial distress.

The International Federation of Accountants (IFAC) is excited to announce that the World Congress of Accountants (WCOA) will be held November 17–20, 2026, in Seoul, South Korea. The Korean Institute of Certified Public Accountants (KICPA) and IFAC will serve as joint hosts, working closely to welcome professional accountants from around the world for the event.

Recognized as a preeminent event for the profession, WCOA brings together Professional Accountancy Organization (PAO) representatives from over 100 countries to strengthen the global accountancy community by sharing experiences, learning and deepening relationships across the profession.  

WCOA 2026 marks the launch of a new biennial format, wherein the event will be held every two years. All accountants, as well as interested members of the public, are invited to participate in WCOA virtually to hear about how the profession is positioning itself for the future. In-person participation will be invite-only and will bring together some of the most experienced and visionary leaders in our field. WCOA will continue to be scheduled alongside IFAC Council meetings.

In-person participants of WCOA 2026 will have the opportunity to join in plenary sessions, panel discussions, and hear from distinguished subject-matter experts. The event will include opportunities to attend networking events, in order to foster collaboration and knowledge exchange among professionals from various sectors. In-person WCOA 2026 attendees will be comprised of IFAC PAO leadership (staff and volunteers), professional services firms, standard-setters, regulators and other government officials, representatives of multilateral and development agencies, and the business and investor communities. Select sessions will be livestreamed so that virtual attendees are included in these important conversations.    

 Lee White, IFAC Chief Executive Officer, said:

"Seoul is a vibrant, innovative, and truly international city—an ideal host for WCOA 2026. At this Congress, the importance of a resilient, adaptable, and global accountancy profession will be front and center. We are honored to partner with our esteemed member, KICPA, to bring the world together here—leaders, colleagues, and friends united by our shared commitment to the public interest. The value of a strong, global profession has never been more pronounced, nor more needed.

We look forward to creating a Congress where every moment matters—whether on stage in a plenary or in a simple conversation between two new acquaintances—each connection will help shape the future of our profession. And of course, we will be engaging deeply on the drivers reshaping that future: sustainability, AI, and how we attract and empower the next generation of talent."

Mr. Woon-Youl Choi, KICPA President said:

“We are delighted that Seoul has been selected as the host city for WCOA 2026. I am confident that WCOA 2026 will serve as a meaningful platform not only to address priorities in accounting, auditing, and sustainability, but also to explore the challenges and opportunities of AI-enabled digital innovation.

Over the years, Korea has consistently strengthened transparency and trust amid a rapidly evolving domestic and global environment. Through this Congress, we look forward to sharing our experience with the global community while co-creating new value for future generations.

KICPA will work closely with IFAC—from program design through on-site delivery—to ensure a high-quality and rewarding experience for all participants. We also invite every participant to experience Seoul’s vibrant culture and dynamic innovation ecosystem during the Congress and to leave with forward-looking insights.”

Africa is a source of growth, innovation, and opportunity, and the accountancy profession is rising to meet the moment. This week in Nairobi, IFAC Connect^TM Africa 2025 brings together public and private sector leaders, regulators, standard setters, and professional accountancy organizations to accelerate a shared vision for sustainable development across the continent.  

Convened by the International Federation of Accountants (IFAC) and co-hosted with the Pan African Federation of Accountants (PAFA) and the Institute of Certified Public Accountants of Kenya (ICPAK), IFAC Connect Africa 2025 launches the second annual IFAC Connect series, designed to ensure international standards and best practices support local solutions. As Africa advances its economic and institutional development, the continent faces both opportunities and challenges across several critical fronts. Navigating these interconnected issues requires coordinated leadership and dialogue across the public and private sectors. IFAC Connect Africa 2025 offers a platform for regional and international leaders to convert insights into action—strengthening trust in institutions, reinforcing the role of professional accountancy organizations and their members, and ensuring the continent is well-positioned to meet the expectations of financial markets, investors, and its citizens. 

As Africa accelerates its transformation, the accountancy profession is central to strengthening governance, advancing sustainability, building talent, enabling regional integration, and fighting financial crime. Over two days, leaders will focus on turning global standards and shared priorities into practical, locally relevant action across both public and private sectors.  

Lee White, IFAC Chief Executive Officer, said: 

“Regional professional accounting leadership is driving economic growth and resilience. With our valued members and partners in Africa, we are all striving for common goals of the use of global standards shaped within local and regional conditions in the public interest. I am privileged to work with many talented colleagues in Africa and we will continue to find opportunities to grow and shape our trusted profession. We are Better Together.” 

Prem Govender, PAFA Vice President, said:  

“Africa’s accountancy profession is stepping forward to shape the continent’s future. This collaboration with IFAC and ICPAK reflects our shared vision of a profession that is inclusive, future-focused, and essential to Africa’s sustainable development.” 

IFAC’s longstanding partnership with PAFA is central to its work in Africa and reflects a shared commitment to strengthening the profession’s capacity to serve the public interest, drive economic transformation, and meet global expectations. From supporting PAFA’s establishment to co-developing strategic initiatives across the continent, IFAC has worked closely with PAFA to amplify Africa’s voice in the global accountancy ecosystem. The two organizations collaborate to align regional priorities with international standards, optimize resources, and ensure consistent, trusted messaging across the profession. IFAC Connect Africa 2025 builds on this strong foundation and serves as the next chapter in a shared effort to deliver global solutions that reflect and respond to Africa’s unique opportunities and realities. 

Prof. Elizabeth Kalunda, Chair, ICPAK: 

“Hosting IFAC Connect Africa 2025 in Nairobi underscores Kenya’s commitment to regional leadership in the profession. Together with IFAC and PAFA, we are driving a transformative agenda grounded in accountability, transparency, and innovation. This event is an opportunity to chart a path that responds to Africa’s needs while contributing meaningfully to the global conversation.” 

Following IFAC Connect Africa 2025, ICPAK will host its Member Practice Forum, featuring a keynote address by Lee White. 

IFAC Connect Africa 2025 is the first of four IFAC Connect events this year followed by MENA in Riyadh in October, Global 2025 in Mexico City in November, and ASIAPAC in Jakarta in December.

The IAASB has released two new resources to further support jurisdictions and stakeholders in adopting and implementing the International Standard on Sustainability Assurance (ISSA) 5000, General Requirements for Sustainability Assurance Engagements.

1. Extracts from ISSA 5000 for Limited and Reasonable Assurance Engagements

In response to stakeholder requests, the IAASB has prepared reference extracts containing only the material in ISSA 5000 relevant to limited assurance engagements and, separately, reasonable assurance engagements. These extracts are designed to help regulators, standard setters, and other stakeholders more easily identify the requirements and application material most relevant to their jurisdictional decisions. They do not amend or override ISSA 5000, the authoritative text of which remains the full standard.

2. Frequently Asked Questions (FAQ) Document on ISAE 3000 (Revised) and ISAE 3410

The IAASB has published FAQs clarifying that, for jurisdictions adopting IAASB standards, ISAE 3000 (Revised) and ISAE 3410 will no longer apply to sustainability assurance engagements once ISSA 5000 becomes effective in December 2026. These FAQs aim to support a smooth transition and consistent application of the new standard.

In addition, the IAASB has updated the adoption information on its website, reflecting the growing global momentum toward adoption of ISSA 5000.

Together with previously published materials, these publications underscore the IAASB’s commitment to supporting adoption and implementation of ISSA 5000 and fostering high-quality, globally consistent sustainability assurance practices.

Access the extracts, FAQs, and adoption information, as well as previously published materials, on the IAASB website here.

The International Public Sector Accounting Standards Board (IPSASB®), developer of IPSAS® Accounting Standards, international accrual-based accounting standards for use by governments and other public sector entities around the world, has issued Amendments to IPSAS Standards as a Result of the Application of IPSAS 46, Measurement. 

IPSAS 46, Measurement introduced a new measurement basis for the public sector called current operational value, a public sector-specific measurement approach designed to reflect the value of assets used to deliver services, rather than to generate cash. Following its release, along with an update to Chapter 7 of the Conceptual Framework, the IPSASB began reviewing how current operational value could apply across existing IPSAS Standards. 

The IPSASB issued a draft of its proposals in August 2024 and incorporated the stakeholder feedback it received to shape the final standard out today. 

“These changes aim to improve how governments and public sector entities report the value of assets they use to deliver services. The pronouncement offers an integrated approach to valuation, guiding entities in measuring the current value of inventories and determining impairment in the public sector,” said Ian Carruthers, IPSASB Chair. “These amendments give public sector financial statement users more relevant, faithfully representative measurement information through broader application of public sector specific measurement guidance.” 

The amendments include the introduction of current operational value in IPSAS 12, Inventories, and IPSAS 21, Impairment Non-Cash Generating Assets, the addition of a definition of accounting estimates to IPSAS 3, Accounting Policies, Changes in Accounting Estimates and Errors, and the enhancement of the terminology in current value measurement disclosures. 

Amendments to IPSAS Standards as a Result of the Application of IPSAS 46, Measurement has an effective date of January 1, 2028. Earlier application is permitted.

It also raises awareness of IPSAS Standards and IPSASB SRS Standards and promotes the adoption and implementation of these to enhance the quality and consistency of practice throughout the world and strengthen the transparency and accountability of public sector finances and sustainable development. The Board receives support from the Asian Development Bank, the Chartered Professional Accountants of Canada, the New Zealand External Reporting Board, the government of Canada, and The World Bank. The structures and processes that support the operations of the IPSASB are facilitated by the International Federation of Accountants (IFAC®).

About the Public Interest Committee 
The governance and standard-setting activities of the IPSASB are overseen by the Public Interest Committee (PIC), to ensure that they follow due process and reflect the public interest.

• Private equity (PE) investment in accounting firms has grown significantly over the past five years in a number of major jurisdictions
• Private equity investment in accounting firms may trigger ethical and independence implications as a result of related structural, strategic and operational changes to a firm
• Staff Alert aims to raise awareness and foster understanding of key ethical and independence matters for accounting firm leadership to consider, both pre- and post-PE investment

A Staff Alert highlighting key ethical matters that accounting firms should pay particular attention to when considering or accepting investment from PE organizations has today been issued by the International Ethics Standards Board for Accountants (IESBA).

Titled  “Private Equity Investment in Accounting Firms: Key Ethics and Independence Considerations”, the Staff Alert draws the attention of professional accountants in public practice, particularly accounting firm leadership, to important ethics and independence provisions in the International Code of Ethics for Professional Accountants (including International Independence Standards) (the Code) that remain applicable both before and after PE investment in an accounting firm. The Staff Alert highlights various possible ethical and independence implications arising from PE investment in accounting firms.

These include:

• From an ethics perspective:
  • threats to compliance with some of the Code’s fundamental principles, such as confidentiality;
  • shifts in a firm’s ethical culture resulting from organizational restructurings, different incentives and evolving growth expectations that may undermine ethical obligations; or
  •  undue pressure to act unethically in pursuit of new revenue goals.
• From an independence perspective:
  • concerns arising from a PE organization holding a controlling interest in the firm while also having a financial interest in the firm’s audit clients;
  • the inclusion of new entities as network firms and the complexities in identifying them, and potential related independence threats, if the firm becomes part of a larger, evolving post-investment structure; or
  • situations where individuals in the PE organization’s management could fall within the Code’s “audit team” concept and the applicable independence framework.

The Staff Alert emphasizes the importance of firms maintaining ongoing monitoring for changes in clients, services, business and network relationships, and other relevant factors with potential ethics and independence implications, both during the pre-investment phase and after completion of the PE transaction, and continuing to act in the public interest.

It also underscores in the context of PE investment that compliance with the Code by firms enhances the quality and consistency of the services they provide and underpins public trust and confidence in their work.

Besides accounting firms, this publication may also be of interest to regulators and audit oversight bodies, jurisdictional standard setters (JSS), private equity entities and other investors, professional accountancy organizations (PAOs), and others with an interest or role in the work of accounting firms.

The development of the Staff Alert has been informed by the IESBA’s ongoing engagement with various stakeholders, including accounting firms, private equity organizations, regulators and oversight bodies, JSS, and PAOs.

The Staff of the International Ethics Standards Board for Accountants (IESBA) has released two implementation support publications to help sustainability assurance practitioners understand and apply the International Ethics Standards for Sustainability Assurance (including International Independence Standards) (IESSA):

• Key Differences: A comparison document outlining the main differences between the IESSA and the corresponding provisions of the IESBA Code applicable to audits of financial statement.
• List of PIE Prohibitions: A list of specific prohibitions in the IESSA applicable to sustainability assurance engagements of public interest entities (PIEs).

The Key Differences Between IESSA and Parts 1 to 4A of the Code provides an overview of how the IESSA compares to the ethics and independence provisions in the IESBA Code that apply to audits of financial statements. It is intended to support firms that already follow the Code in understanding and implementing the IESSA for sustainability assurance engagements. For reference purposes, the publication is accompanied by a marked-up version of the IESSA showing changes from the corresponding sections of the extant Code.

The List of Prohibitions for PIEs in IESSA summarizes the specific interests, relationships, non-assurance services and other circumstances prohibited under the IESSA when performing sustainability assurance engagements for PIEs. It is intended as a high-level reference to help sustainability assurance practitioners in further understanding the prohibitions in the IESSA.

Jurisdictional standard setters, regulators and oversight bodies, professional accountancy organizations, educational institutions and other stakeholders may also find the publications useful.

These new resources are part of a comprehensive implementation support program the IESBA has put in place—a strategic priority aimed at promoting the adoption and consistent and effective implementation of the IESSA, which becomes effective in December 2026. Led by a dedicated Adoption and Implementation Working Group, this effort includes a growing suite of guidance materials, webinars, and other resources to back the rollout of the Global Ethics Sustainability Standards.
