Prevent it on your watch and learn from the Société Générale calamity.

When I read about the €7 billion loss at Société Générale (SG) I thought, "This can't be happening AGAIN!" But, apparently, it can and it has. One of the many speculations about what triggered the SG debacle is spreadsheet fraud. Even organizations with great internal controls often overlook controls when it comes to spreadsheets. It's just something no one really thinks about, except a few wily employees bent on deceit.
It will probably be years before the whole SG story unfolds and we find out exactly what happened. However, a theory circulating in IT security and compliance circles indicates that inadequate, spreadsheet-based internal controls may have played a part in allowing trader Jerome Kerviel to build up his positions. As you already know, these positions eventually resulted in the tremendous loss for the bank. There has been speculation that, in addition to disguising his trades through a fictitious company and a colleague's accounts, Kerviel was able to circumvent SG's internal warning systems by opening and manipulating Excel spreadsheet reports used by managers to monitor traders' activities.
But, this is not a lone example of how unscrupulous employees can manipulate electronic spreadsheets for personal gain. One of my favorite stories involves spreadsheets and unclaimed property. In this fraud, a midsize manufacturer located in the Northeast tracked its unclaimed property on a spreadsheet by updating it each time the company had an uncashed check. In this case, the employee simply changed the name of the intended payee from whoever it was to his own. How was he caught? He put his own name down for a $300,000 claim and the claim stood out like a red flag. It should be noted that the state of Delaware recently experienced a similar fraud, although in that case the employee was a tad smarter and used friends' names for the claim and took a kickback from them.
What You Can Do
First, recognize the potential danger of spreadsheet fraud and every organization is vulnerable. Employ the same strong internal controls and segregation of duties with your spreadsheets as you do in all other parts of your accounting and finance operations:
When your employees create workarounds to fill in when the accounting package doesn't handle your unique requirements, it should be a red flag for you because this is what provides opportunities for those looking to steal from you.
ConclusionBy recognizing that you might be vulnerable to spreadsheet fraud and by taking anti-fraud prevention steps, you can protect your company from a major loss. And, if you have already taken the appropriate steps, you should be congratulated on your foresight. Too bad Societe Generale didn't have you on its staff!
