Fraud In Your Organisation


Occasionally, the way people behave might suggest that they are committing a fraud.  This behaviour creates signs that are referred to as 'red flags'.  Individually, some "red flags" may not be any cause for immediate concern; however several "red flags" together, may result in suspicions being raised.  Individuals may also communicate desire for personal financial gain whilst being in considerable debt.

Some examples of "red flags" include;

1) An employee who has control of a process from start to finish with no segregation of duties;
2) Monitory transactions taking place during unusual times of the day, with increased frequency, for unusual amounts or to suspicious recipients;
3) Internal controls that are not enforced, or often compromised by higher authorities;
4) Discrepancies in accounting records and unexplained items on reconciliations;
5) Inconsistent, vague or implausible responses arising from inquiries;
6) Significant changes in personal behaviour;
7) Unusual discrepancies between the client's records and confirmation replies;
8) Missing inventory or physical assets;
9) Excessive voids or credits;
10) Missing documents, or only photocopied documents available;
11) Common names or addresses of payees or customers;
12) Alterations on documents (eg back dating);
13) Duplication (eg duplicate payments);
14) Audit findings deemed to be errors or irregularities;
15) Collusion among employees, where there is little or no supervision
