What is the group engagement partner?
The group engagement partner is responsible for directing and supervising the group audit engagement and its overall performance. This mirrors the engagement partner role under ISA 220 (Revised), but ISA 600 (Revised) adds specific group audit requirements. The partner must be sufficiently involved in the work of component auditors to take responsibility for the group audit opinion.
Under ISA 600 (Revised).13, the group engagement partner must determine that the group engagement team has the competence and capabilities to perform the group audit. The partner's involvement extends to reviewing the risk assessment across components and evaluating whether the audit evidence obtained from component auditors is sufficient. Where it is not, the partner determines what additional procedures are needed at the group level.
ISA 600 (Revised).17 addresses the partner's responsibility for the overall group audit strategy. The partner cannot sign the group auditor's report without being satisfied that sufficient appropriate audit evidence has been obtained from the work performed across all components.
Key Points
- The group engagement partner bears ultimate responsibility for the group audit opinion.
- The revised standard expanded the partner's required involvement in risk assessment and component auditor oversight.
- Delegation to the group engagement team does not transfer responsibility from the partner.
- Inspection findings frequently cite insufficient partner involvement in the group scoping and risk assessment.
Worked example: Leitner Bau AG
Client: Austrian construction group, FY2024, consolidated revenue €180M, IFRS reporter, four subsidiaries, with the two largest in Austria and one each in Germany and Croatia.
Determine team competence
The partner confirms that the group engagement team includes a senior with group audit experience and that the Croatian component auditor holds the required local qualification. The partner also confirms the German component auditor's independence.
Direct the risk assessment
The partner reviews the group engagement team's identification of risks of material misstatement across all four components. The partner identifies that the Croatian subsidiary's construction contract accounting (percentage-of-completion under IFRS 15) presents a significant risk that the team's initial assessment had classified as moderate. The partner directs an upgrade of the risk classification.
Evaluate component auditor work
At completion, the partner reviews the Croatian component auditor's report on revenue and the German component auditor's work on a €9M intercompany loan. The partner requests additional procedures from the Croatian component auditor on the cost-to-complete assumptions. Additional evidence is received and evaluated before signing the group auditor's report.
The group engagement partner's documented involvement in risk assessment and at completion demonstrates the active oversight ISA 600 (Revised) requires. A partner who delegates without reviewing cannot sign the group opinion.
What reviewers and practitioners get wrong
The FRC's annual inspection reports have repeatedly identified insufficient group engagement partner involvement in the group audit as a recurring finding. The pattern is consistent: the partner delegates the component auditor relationship entirely to the group engagement team manager and does not review the risk assessment or component auditor conclusions before signing.
Partners sometimes treat the group engagement partner role as administrative (signing the opinion and the engagement letter) rather than substantive. ISA 600 (Revised).13 requires the partner to be involved in the direction and supervision of the group audit, not just the sign-off. The gap between what the standard requires and what some partners actually do is the inspection finding waiting to happen.
