Internal Auditors' Role in Fraud Risk Management:
* Internal auditors evaluate management's commitment to overseeing and addressing fraud risks as part of their assurance role.
Why A is Correct:
* Oversight of fraud risk management is a management responsibility, and internal auditors assess whether this responsibility is effectively retained and executed.
Why Other Options are Incorrect:
* B:Reporting to regulators is not a core responsibility of internal auditors.
* C:Internal auditors provide evaluation, not direct oversight.
* D:Attesting financial statement accuracy is the responsibility of external auditors, not internal auditors.

ISO 31000:2018 emphasizes that effective risk management must be integrated into all activities across the organization-not just high-risk ones.
"An effective and efficient risk management program... is integrated into all organizational activities, is structured and comprehensive, and is customized and proportionate to the organization's operations and objectives." Reference:ACFE Fraud Examiners Manual, 2020 International Edition -Fraud Risk Management, Section
4.806.

Internal Audit Reporting Responsibilities:
Internal audit must maintain open communication with senior management and the board to ensure appropriate handling of fraud-related issues.
Establishing reporting protocols in advance ensures timely and consistent responses when fraud occurs.
Analysis of Other Options:
B: Periodic reporting is optional:Reporting fraud risks is a required responsibility.
C: Non-disclosure:Fails to fulfill the role of internal audit in governance and accountability.
D: No communication with the board:Misrepresents the internal audit's role in fraud oversight.
Conclusion:Discussing reporting protocols proactively with senior management and the board is the correct approach.
