The correct approach aligns with the International Standards for the Professional Practice of Internal Auditing (Standards), particularly Standard 2400: Communicating Results. The auditor must promptly discuss material errors to prevent ongoing misstatements. Immediate correction ensures timely remediation and reduces the risk of material misstatement persisting in the financial records. Additionally, if the error is resolved before the engagement concludes, it may not necessitate inclusion in the final report, as per the guidance on handling material findings (Practice Advisory 2410-1). This approach also demonstrates collaboration and alignment with management, fostering trust.
