IAASB Modernizes Its Standard for Group Audits in Support of Audit Quality

The International Auditing and Assurance Standards Board (IAASB) today released International Standard on Auditing (ISA) 600 (Revised). The revised standard addresses special considerations that apply to audits of group financial statements (group audits). Group audits are often more complex and challenging than single-entity audits because a group may have many entities or business units across multiple jurisdictions, and component auditors may be involved. The revised standard becomes effective for audits of group financial statements for periods beginning on or after December 15, 2023.

“ISA 600 (Revised) is a significant step forward to enhance the consistent performance of quality group audit engagements and thereby supports users’ interests and broader financial stability,” said Tom Seidenstein, IAASB Chair. “Group audits is an area identified by regulators requiring attention. The changes in the standard build off other recent IAASB revisions, such as the revisions to the quality management standards, and should enhance audit quality by strengthening the accountability of group auditors and clarifying the interactive relationship between group and component auditors.”

ISA 600 (Revised) includes a robust risk-based approach to planning and performing a group audit. The approach focuses the group auditor’s attention and work effort on identifying and assessing the risks of material misstatement of the group financial statements and designing and performing further audit procedures to respond to those assessed risks. It also recognizes that component auditors can be, and often are, involved in all phases of the group audit. The standard furthermore promotes a clear, proactive and scalable approach for group audits that can be applied to today’s evolving group audit structures.

The IAASB also developed a Basis for Conclusions and factsheet to support the implementation, which are also available on the IAASB’s website.
