This article focuses on the key areas of group audit, highlighting sections of ISA 600 (Revised), Special Considerations – Audits of Group Financial Statements (Including the Work of Component Auditors). Candidates should be familiar with the standard prior to sitting the Advanced Audit and Assurance examination (AAA) exam.
The audit of group financial statements is an area frequently examined in the AAA exam. It can be tested at any stage of the audit cycle and therefore in any section of the examination. It is important that candidates are able to identify risks arising from aspects of group audits and the responsibility of auditors in this regard.
ISA 600 (Revised) deals with special considerations that apply to a group audit, including when component auditors are involved. The standard aligns the standard with recently revised standards which emphasise the assessment of risk, including ISQM1 and ISA 220 (Revised) and ISA 315 (Revised 2019). There is increased emphasis on the responsibilities of auditors s relating to professional scepticism; planning and performing a group audit; two-way communications between the group auditor and component auditors; and documentation.
ISA 600 (Revised) sets out the responsibilities of the group auditor for providing the audit opinion on the group financial statements, including components of such as subsidiaries, associates, joint ventures and non-controller entities.
The components may be audited by the group auditor or may be audited by a different firm of auditors known as the ‘component auditors’. The group auditor will provide an opinion on the consolidated financial statements, it is therefore essential that they are satisfied with work completed by component auditors or local audit teams. The group auditor will form an opinion on the parent company’s individual financial statements.
It is important for students to note that under the risk-based approach, component auditors can be, and often are, involved in all stages of the group audit.
1. Group audit acceptance considerations
Prior to acceptance of a new engagement as group auditor, or indeed the continuation of an existing group audit appointment, the group engagement partner must determine whether they can reasonably expect to obtain sufficient appropriate evidence in relation to the consolidation process including the financial information of any components of the group in order to form their group audit opinion. Often, a group audit engagement will be presented with a component auditor which gives rise to further considerations regarding acceptance or continuation of the group audit.
