Omnipresence of Fraud!

• Fraud is omnipresent and it isas old as human civilisation!

• Kautilya, ancient Indianstatesman (2nd century B.C)-well known for his famoustreatise on statecraft andpolicy, ‘Arthashastra’,described in detail– forty different ways in which

state funds could be embezzledduring his time; and

– laid down an elaboratepunishment procedure.

“Whether one wishes or not,honey or poison kept on tonguegets tasted eventually. So it is,corruption and wealthaccumulation by governmentofficials. It is highly likely thatthey do accumulate more or lesswealth by corruption in theirtenure.”

– Kautilya

The Magnitude of LossesACFE

• Approximately two-thirdsof the cases reportedtargeted privately held orpublicly ownedcompanies and these for-profit organizationssuffered the largestmedian losses among thetypes of organizationsanalysed, at $180,000and $178,000,respectively.

• Of the cases involving agovernment victim, thosethat occurred at thefederal level reported thehighest median loss($194,000), compared tostate or provincial($100,000) and localentities ($80,000).

• (ACFE 2016 Report to the Nations on Fraud and Abuse)

PwC

• 41 percent of therespondents fromgovernment/state ownedenterprises reported thattheir organisations hadsuffered economic crimein the last 12 months.

• The same survey showsthat: (a) procurementfraud has more thandoubled in the publicsector since 2012; and (b)24 percent of thegovernmentorganisations surveyedworldwide sufferedlosses in the past 24months that were inexcess of $1 million.

• (2014 PwC Global Economic Crime

Survey)

My Study

• Based on secondary data;

• Losses of over $40 millionin five years;

• Almost every departmentof the government hadsuffered frauds;

• The perpetrators wereinsiders in 80 percent ofthe cases reported;

• Cash-on-handmisappropriation was themost frequently followedscheme; and

• 80 percent of therevenue was lost beforecrediting (skimming); andthe primary (61 percent)reason for the controlweaknesses was ‘notfollowing the prescribedchecks’.

Some Commonly Used Detection Techniques

30

• Data Mining: To discover previously hiddenpatterns and attributes in data, pointing not onlyto fraudulent transactions, but also to newmarkets and products, is the new challenge forInformation Systems auditors.

• Other techniques: Case-based reasoning tools andneural networks, data matching etc.,

Estimates of requirements prepared in piecemeal to avoid procurement procedures set for high value purchases.

Specifications prepared to exclude all but certain favoured suppliers.

Estimates prepared using costs higher than the market price.

Single work divided into several small components so that it can be approved within the initiator’s authority.

Material purchased directly at the manufacturer’s price that falsely claim to meet the required specifications.

Unusually low time given for bidding to avoid competition.

Tailored conditions of payment allow unconditional secured advance, mobilisation advance etc.,
