13. Which situation is a violation of the American Institute of Certified Public Accountant Code of Conduct rule?
Answer: B
An external auditor owns a substantial interest in a company being audited.
This situation represents a clear violation of the American Institute of Certified Public Accountant Code of Conduct rule. The principle of independence is fundamental to the integrity of the audit process, and owning a substantial interest in the company undermines that independence.
A) An internal auditor is testing transactions in an internal accounting system.
This option is not a violation of the Code of Conduct. Internal auditors are expected to evaluate and test transactions within the internal accounting system as part of their role, ensuring compliance and effectiveness of the internal controls.
B) An external auditor owns a substantial interest in a company being audited.
This option is indeed a violation of the Code of Conduct. An external auditor having a substantial financial interest in the audited company creates a conflict of interest, compromising the auditor's objectivity and independence, which are crucial for reliable financial reporting.
C) An internal auditor recommends internal control systems to the company.
This scenario does not violate the Code of Conduct. Internal auditors are encouraged to provide recommendations for improving internal control systems, as this is part of their responsibility to enhance the organization’s governance and risk management processes.
D) An external auditor was part of the prior year's audit team.
This situation is not a violation on its own. While there are rules regarding the rotation of audit partners and teams to maintain independence, being part of the previous year's audit team does not automatically violate the Code of Conduct unless it compromises independence due to specific circumstances.
Conclusion
The correct answer, B, highlights a significant breach of ethical standards, as financial interests in a client can severely impair an auditor’s objectivity. Conversely, options A, C, and D involve actions that fall within acceptable professional practices and do not compromise the auditor's independence or integrity. Thus, only option B clearly violates the principles set forth by the American Institute of Certified Public Accountants.
