Which of the following is a true statement about an external auditor's involvement in internal investigations? Group of answer choices If the external auditor receives information from a whistleblower, they usually do not share it with management, but conduct the internal investigation as part of the audit procedures. Since internal investigations are usually led by lawyers, and the work is usually subject to legal privileges, auditors rarely have any access to information arising from the investigation. External auditors sometimes lead or participate in the internal investigations, since they are knowledgeable about the company's systems. An external auditor should carefully consider the results of an internal investigation and determine whether to revise the nature, timing and extent of audit procedures.
