The Better Way of Applying Benford’s Law for Fraud Detection

Applying Benford’s Law on large collections of data is an effective way of detecting fraud. In this article, we?ll introduce you to Benford’s Law, talk about how auditors are employing it in fraud detection, and introduce you to a more effective way of integrating it into an IT solution.

Benford’s Law in a nutshell

Benford’s Law states that certain data sets – including certain accounting numbers – exhibit a non-uniform distribution of first digits. Simply put, if you gather all the first digits (e.g. 8 is the first digit of ?814 and 1 is the first digit of ?1768) of all the numbers that make up one of these data sets, the smallest digits will appear more frequently than the larger ones.

That is, according to Benford’s Law,

1 should comprise roughly 30.1% of all first digits;
2 should be 17.6%;
3 should be 12.5%;
4 should be 9.7%, and so on.

Notice that the 1s (ones) occur far more frequently than the rest. Those who are not familiar with Benford’s Law tend to assume that all digits should be distributed uniformly. So when fraudulent individuals tinker with accounting data, they may end up putting in more 9s or 8s than there actually should be.

Once an accounting data set is found to show a large deviation from this distribution, then auditors move in to make a closer inspection.

Benford’s Law spreadsheets and templates

Because Benford’s Law has been proven to be effective in discovering unnaturally-behaving data sets (such as those manipulated by fraudsters), many auditors have created simple software solutions that apply this law. Most of these solutions, owing to the fact that a large majority of accounting departments use spreadsheets, come in the form of spreadsheet templates.

You can easily find free downloadable spreadsheet templates that apply Benford’s Law as well as simple How-To articles that can help you to implement the law on your own existing spreadsheets. Just Google “Benford’s law template” or “Benford’s law spreadsheet”.

I suggest you try out some of them yourself to get a feel on how they work.

The problem with Benford’s Law when used on spreadsheets

There’s actually another reason why I wanted you to try those spreadsheet templates and How-To’s yourself. I wanted you to see how susceptible these solutions are to trivial errors. Whenever you work on these spreadsheet templates – or your own spreadsheets for that matter – when implementing Benford’s Law, you can commit mistakes when copy-pasting values, specifying ranges, entering formulas, and so on.

Furthermore, some of the data might be located in different spreadsheets, which can likewise by found in different departments and have to be emailed for consolidation. The departments who own this data will have to extract the needed data from their own spreadsheets, transfer them to another spreadsheet, and send them to the person in-charge of consolidation.

These activities can introduce errors as well. That’s why we think that, while Benford’s Law can be an effective tool for detecting fraud, spreadsheet-based working environments can taint the entire fraud detection process.

There?s actually a better IT solution where you can use Benford’s Law.

Why a server-based solution works better

In order to apply Benford’s Law more effectively, you need to use it in an environment that implements better controls than what spreadsheets can offer. What we propose is a server-based system.

In a server-based system, your data is placed in a secure database. People who want to input data or access existing data will have to go through access controls such as login procedures. These systems also have features that log access history so that you can trace who accessed which and when.

If Benford’s Law is integrated into such a system, there would be no need for any error-prone copy-pasting activities because all the data is stored in one place. Thus, fraud detection initiatives can be much faster and more reliable.

IT Risk and Control Solutions Specialists – Why you need them more than ever

Over the years, the capabilities of IT systems have certainly grown by leaps and bounds. But so have the risks that accompany them. Countless threats to IT systems now exist that are capable of seriously disrupting business operations. That’s why companies have to conduct assessments aimed at making sure their systems are still capable of functioning effectively, efficiently, and securely all the time.

If you think you’ve been lucky enough to be spared from these threats, then maybe it’s because you haven’t conducted a risk assessment on your IT system recently. All too often, we hear of CIOs who believed their IT system was in tip-top condition, only to be later caught off-guard by a critical system breakdown that would eventually cripple their business for days or weeks.

More information assets to look after

If, before, you only had to worry about regular office applications, workstations, a LAN and a server, today’s varied and more sophisticated information assets are more challenging to maintain.

In addition to network operating systems, database management systems, content management systems, email systems, virtualization platforms, document management systems, business intelligence applications, and accounting software, a typical enterprise may also have to look after firewalls, intrusion detection systems, storage and backup systems, and data loss prevention systems, to mention a few.

These understandably require the services of experts spanning a wide range of skill sets.

Rising threats to corporate identity and privacy

Individuals are no longer just the ones being preyed upon by identity thieves. Businesses can now be subject to corporate identity theft as well. You could wake up one day finding your business already accused of carrying out illegal activities, a big chunk of your money gone, and your directors? seats already occupied by complete strangers.

To make things worse, corporate threats aren’t just coming from the outside.

Threats to corporate privacy, for instance, can come from within the organisation itself. Sensitive information like trade secrets and financial data are often leaked out (purposely or inadvertently) by employees. This is largely caused by the ever growing number of options for communications and transferring data (e.g. emails, instant messaging, blogs, social networking sites, ftp, P2P, etc.).

Greater challenges in designing, developing, and implementing policies and programs

Laws and regulations like SOX and Solvency II, which have direct impacts on IT, are on the rise. That is why corporate policies and programs now require sweeping changes. You now have to be more deliberate in integrating IT when establishing governance, internal controls, change management, incident management, and performance management.

A solid understanding on widely accepted frameworks and good practices like COBIT, COSO, and CMMI will help you considerably in such undertakings. Using these frameworks as guidelines will not only help you keep your policies and programs attuned to the times, they will also keep you in compliance with regulations.

Increasing demand for disaster recovery and business continuity capabilities

Every time you have a down time, you increase the probability of losing your customers to competitors. The longer the down time, the greater that probability becomes. Therefore, when a major disruption strikes, you should be able to recover at the soonest. If possible, you should be able to deliver products and services as usual.

This of course requires spending to increase your disaster recovery (DR) and business continuity (BC) capabilities. Are you ready for it? Migrating your IT infrastructure from traditional systems to the latest technologies that are better equipped for BC/DR requires careful planning and implementation to ensure an optimal return on investment.

What Sub-Metering did for Nissan in Tennessee

When Nissan built its motor manufacturing plant in Smyrna 30 years ago, the 5.9 million square-foot factory employing over 8,000 people was state of art. After the 2005 hurricane season sky-rocketed energy prices, the energy team looked beyond efficient lighting at the more important aspect of utility usage in the plant itself. Let’s examine how they went about sub-metering and what it gained for them.

The Nissan energy team faced three challenges as they began their study. They had a rudimentary high-level data collection system (NEMAC) that was so primitive they had to transfer the data to spread-sheets to analyse it. To compound this, the engineering staff were focused on the priority of getting cars faster through the line. Finally, they faced the daunting task of making modifications to reticulation systems without affecting manufacturing throughput. But where to start?

The energy team chose the route of collaboration with assembly and maintenance people as they began the initial phase of tracking down existing meters and detecting gaps. They installed most additional equipment during normal service outages. Exceptions were treated as minor jobs to be done when convenient. Their next step was to connect the additional meters to their ageing NEMAC, and learn how to use it properly for the first time.

Although this was a cranky solution, it had the advantage of not calling for additional funding which would have caused delays. However operations personnel were concerned that energy-saving shutdowns between shifts and over weekends could cause false starts. ?We’ve already squeezed the lemon dry,? they seemed to say. ?What makes you think there?s more to come??

The energy team had a lucky break when they stumbled into an opportunity to prove their point early into implementation. They spotted a four-hourly power consumption spike they knew was worth examining. They traced this to an air dryer that was set to cyclical operation because it lacked a dew-point sensor. The company recovered the $1,500 this cost to fix, in an amazing 6 weeks.

Suitably encouraged and now supported by the operating and maintenance departments, the Smyrna energy team expanded their project to empower operating staff to adjust production schedules to optimise energy use, and maintenance staff to detect machines that were running without output value. The ongoing savings are significant and levels of shop floor staff motivation are higher.

Let’s leave the final word to the energy team facilitator who says, ?The only disadvantage of sub-metering is that now we can’t imagine doing without it.?

Competencies, Roles and Responsibilities of Lead Assessors

Any organisation that opts for energy audits, Display of Energy Certificates and Green Deal Assessments needs a lead assessor to review the chosen ESOS compliance routes. The Derivative provides that energy audits should be carried out independently by qualified and accredited experts. Additionally, these audits should be implemented as well as supervised by independent authorities under the national legislation.

Lead assessors undertake several roles in ESOS assessments. He or she is the one responsible to take the lead of the entire assessment team, prepare the plan, conduct the meetings and submit the formal report to governing authorities. Nevertheless, selecting an appropriate lead assessor is an important element that every organisation should carefully consider.

Competencies Requirements of Lead Assessors

Lead assessors should be knowledgeable enough with in-depth expertise in carrying out energy efficiency assessment. They should also possess foundational, functional and technical competencies to deliver the task effectively. Likewise, consider the assessors? sector experiences, familiarity with your business? technologies and properties, and accreditation with prescribed standards.

As you choose your lead assessor, contemplate on the skills and qualifications that would give your organisation benefits.

Roles and Responsibilities of Lead Assessors

The business organisation is responsible for the overall legal ESOS compliance. Moreover, here are some of the roles and responsibilities that lead assessors should assume in ESOS assessments.

The lead assessor agrees on the audit methodologies that the organisation would undergo in new audits. He or she agrees with the ESOS participant regarding the audit timetable, sampling approach and visits required. It is also the lead assessor?s role to identify the opportunities on energy saving and assist in calculating the cost savings from the measures taken. During the ESOS audits, the lead assessor determines the energy use profiles, presents the recommendations and reviews the entire assessment as a whole. Furthermore, he or she should maintain the evidence pack of the ESOS to uphold the audit’s credibility, its findings and recommendations.

Finding Lead Assessors

Energy and environment professionals would only be able to demonstrate their expertise as lead assessors upon registering in a professional body accredited by the Environment Agency. Any business that needs a lead assessor is advised to check on the EA?s website to see the details of approved registers.

Lead assessors can either be in-house experts or external professionals. However, they should be able to provide proof of membership as an approved register to take the role of a lead assessor. If the organisation has an internal lead assessor, the company should then take the final ESOS assessment to two board-level directors that would sign the formal report.

Indeed, the lead assessor is an organisation’s partner when it comes to delivering great results. With good professional conduct and excellent management of an assessment team, the lead assessor can help achieve breakthrough energy efficiency strategies. More than anything else, the organisation will benefit from maximum energy savings opportunities ahead. Thus, every qualified business enterprise should invest in finding the best lead assessor to guide them towards success.
