Detection of Frauds by the Auditor

Fraud is, by definition, deliberately concealed — so detecting it demands sharper, less predictable techniques than the routine checking used for errors.

1. Surprise checks. Announced audit visits give a dishonest employee time to cover their tracks; unannounced, surprise verification of cash-in-hand, petty cash, and physical stock is far more likely to catch a fraud in progress.

2. Scrutiny of unusual entries. Journal entries passed outside the normal course of business, round-sum adjustments, entries made just before or after the year-end, and transactions lacking proper supporting documents all deserve closer attention.

3. Examining internal controls. A weak system of internal check — particularly a lack of segregation of duties (the same person both handling cash and recording it, for example) — is exactly the gap that makes misappropriation possible; the auditor evaluates the internal control system itself as part of assessing fraud risk (this connects directly to Internal Control System, studied later in this course).

4. Independent, external confirmation. Verifying balances directly with third parties — bank confirmations, direct confirmation of debtor/creditor balances, physical verification of stock by the auditor personally rather than relying solely on management's figures — reduces the risk of being misled by manipulated internal records. …
