In the most rigorous assurance engagements, what is evaluated to assess data integrity?

• A. The reported information, the source data, and the organization's internal controls.
• B. Only the auditor's opinion.
• C. External market conditions.
• D. Marketing materials.

Answer: (A)

Data integrity in rigorous assurance engagements is evaluated by examining the reported information, the source data, and the organization's internal controls. The source data are the original records and raw inputs that feed the information; auditors verify they are complete, accurate, and properly authorized. The reported information is what is communicated to users, so auditors trace it back to the source data and test for consistency and accuracy, ensuring disclosures are complete and fair. Internal controls are the policies and processes that govern data capture, processing, and reporting; assessing their design and operating effectiveness helps determine the risk of errors and misstatements. The auditor's conclusion by itself does not prove data integrity, because it depends on evidence from the source data and controls; external market conditions and marketing materials are not the relevant focus for assessing the integrity of the data being assured.
