Herbal Pharma Inc.: Conducting an Effective Group Audit*

As the relative weight of global economic activity continues to shift toward non-OECD countries (OECD 2018), audit firms are more likely to encounter clients with significant business operations in foreign jurisdictions. The associated need to engage and oversee local component auditors in these jurisdictions can lead to challenges arising from different business cultures and the resulting intra-audit miscommunications. Audit deficiencies related to these challenges have been detected by regulators (PCAOB 2011, 2010; CPAB 2012, 2015). Standard setters such as the IAASB and the Auditing and Assurance Standards Board (AASB) have responded by issuing an exposure draft proposing revisions to ISA 600 (IAASB 2020) and CAS 600 (AASB 2020) to strengthen the auditor's approach and provide enhanced guidance to practitioners. In light of this evolving area of assurance, this case was developed to deepen students' understanding of both group and component audits in an international context. The case takes the perspective of the group auditor and features an audit senior in a specialized role overseeing the component audit of a client's increasingly material Chinese subsidiary. Deficiencies in the prior year component audit, along with a change in the component auditor, further underlines the importance of robust risk analysis for the upcoming engagement.
