Fraud examination

Fraud examination is a structured process for resolving fraud allegations, from predication through evidence gathering, interviews and reporting, as defined and taught by the Association of Certified Fraud Examiners.

Definition

The ACFE describes fraud examination as a methodology for resolving fraud allegations from inception to disposition. It begins with predication, meaning facts that would lead a reasonable, trained professional to believe a fraud has occurred, is occurring or will occur. It then moves through evidence collection, document and data analysis, interviews, and a report. Examiners protect the chain of custody and avoid conclusions on guilt.

Why it matters in an audit or review

An auditor who suspects fraud under AU-C 240 communicates with the right level of management and those charged with governance, and considers the effect on the audit. A fraud examination goes further than an audit procedure and is usually performed by a separate team, often through counsel.

Example

Illustrative: payroll analytics flag three employees who share a bank account. Predication exists, so the examiner pulls personnel files, tests the payroll approvals and interviews the payroll supervisor last, after the documents are secured.

Common mistakes

  • Interviewing the suspect before securing documents.
  • Starting an examination with no predication.
