While meeting with the senior management of Dove Enterprises, Inc., a national retailer of shower gel and other toiletries products throughout the United States, the external auditors have been advised that a member of the audit committee is also a major vendor of the client. Based on this information, what is the auditors' most likely course of action? The auditor should interview the director in question, and obtain written assurances that there is no fraud occurring, for documentation purposes and inclusion in the audit file. O The auditor should exercise an appropriate level of professional skepticism and plan to conduct increased procedures in this area. The auditor should consider immediately withdrawing from the engagement, citing independence concerns. The auditors should advise management that this represents a serious conflict of interest, and request they adopt a company policy prohibiting this.
