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.

Choosing Routes for ESOS Compliance

Along the introduction of Energy Savings Opportunity Scheme in UK is the quick emergence of various companies that offer ESOS compliant services. While some energy audit providers can help, qualified businesses should understand what their compliance options are, how these routes work and learn both the pros and cons in order to carefully take their pick.

Independent ISO 50001 Certification

ISO 50001 comprises the integration and application of processes geared to motivate energy saving and overall improvement. Simply stated, it is a framework that drives the organisation’s governance to realise energy saving strategies by allocating resources and participating in energy management. The good thing about ISO 50001 is that it includes an energy review that documents ideas and opportunities to save more energy.

However, ISO 50001 does not obligate organisations to cover 90% of their overall energy consumption. In case of partial coverage, the company needs to undergo additional energy assessments to evaluate all the significant energy consumption areas.

In order for an ISO 50001 certification to be valid, it must be certified by the United Kingdom Accreditation Service (UKAS), by an accreditation body which is a member of the International Accreditation Forum, or by a body accredited by another EU member state?s national accreditation body.

Display Energy Certificates and Green Deal Assessments

These two kinds of energy assessment reports can also contribute to ESOS compliance. Both of them are carried out by qualified lead assessors and valid for 10 years. However, they are only based on the building structures and services. They do not cover the overall significant areas in energy consumption. Since these reports are valid for 10 years, they would be used for two ESOS reporting periods. Thus, they would not be as current as the ISO 50001 certification. Aside from that, the assessments are purely based on energy efficiency and anyone can qualify to use the software that produce the certifications after taking the accreditation course.

Energy Audits

A successful energy audit leads to better understanding of the company?s energy consumption, identify alternatives, determine cost-effective energy saving opportunities and stimulate energy efficiency. Energy audits are beneficial to the organisation. What makes it complex is that the organisation applying it, needs to clearly define the scope and type of energy audit to use in order to comply with ESOS. Furthermore, the organisation also has to identify the teams that would be competent enough to do the audit work for the building, transport and industrial area, respectively.

Each route is not formed equal. Thus, organisations have the option to either choose one or combine the routes and meet their company needs. The options mentioned are different approaches to ESOS and the core value is to grab the opportunity towards acquiring more savings through efficient energy system.

How Bouygues manages an Empire-Sized Footprint

Bouygues is into telecoms / media, and building and road construction. It also knows it has to watch its energy footprint closely. Owning 47% of energy giant Alstom keeps it constantly in the media spotlight. Shall we find out more about its facility management policies?

The journal Premises and Facilities Management interviewed MD Martin Bouygues on his personal opinions concerning managing energy consumption in facilities. He began by commenting that this was hardly a subject for the C-Suite in years gone by. Low-level clerks simply paid the bills following which the actual amounts were lost in the general expenses account. That of course has changed.

Early pressure came from soaring energy bills, which were pursued by a whole host of electricity-saving gadgets. However, it was only after the carbon crisis caught business by surprise that the link was forged to aerial pollution, and the social responsibilities of big business to help with the solution. The duty to have an energy strategy became an obligation eagerly policed by organisations such as Greenpeace.

Unsurprisingly, Martin Bouygues? advice begins with keeping energy consumption and its carbon footprint as high up on the agenda as health and safety. ?It needs bravery and a lot of hard work to get it there,? he says, ?so perseverance is the key?. 

The company has developed proprietary software that enables it to pull data from remote sensors in more than 80 countries every fifteen minutes. A single large building can contribute 50 million data items annually making data big business in the system. Every building has an allocated energy performance contract against which results are reported monthly, as a basis for reviewing progress.

The system is intelligent and able to incorporate low-occupancy periods such as weekends and public holidays. What is measured gets managed. We all know that, but how many of us apply the principle to our energy bills. With assistance from ecoVaro, the possible becomes real.

We offer a similar service to the Bouygues model with one notable exception. You don’t buy the software and you only pay when you use it. Our systems are simply designed for busy financial managers.

ESOS ? Why we must have it

The 9,000 big UK businesses directly affected by the new Energy Saving Opportunity Scheme could save UK?250 million between them, or an average UK?27,000 each, if they reduced electricity consumption by just 1%. The total amount is equal to the output of five power stations, at a time when Britain?s grid is under strain.
On 26 November 2014, UK Energy and Climate Change Secretary Ed Davey met with over 100 opinion makers from businesses, charities and universities at the Institute of Directors. The gist of what he presented was:

  • ?Britain?s big firms are spending around ?2.8 billion extra each year on inefficient energy technologies ? the equivalent output of nearly five power stations;
  • Now is the time to seize the opportunity with ESOS ? and organisations up and down the country are already gearing up to make changes to save energy, save money and save the environment.
  • If business did what business is supposed to do [that is innovate to make money] and act and invest, it will save ? and that’s the bottom line.?

The environmental benefits are as important although EcoVaro agrees with Ed Davey for taking a pecuniary approach. Businesses above the threshold of 250 staff and a balance sheet of UK?34 million would have not achieved their status unless they spent their money wisely.
The discussion panel included Rhian Kelly (Director of Business Environment at CBI), and Paul Ekins (Director UCL Institute for Sustainable Resources & Deputy Director of the UK Energy Research Centre). Hugh Jones, Managing Director, Advisory at the Carbon Trust responded to Ed Davey?s remarks by commenting:

  • ?At the Carbon Trust we have already engaged with hundreds of businesses on ESOS, helping to explain how they can achieve compliance while also making significant energy savings and cutting carbon.
  • Businesses often aren’t aware of opportunities in energy efficiency, or they don’t realise how attractive the paybacks can be. By requiring companies to understand exactly how they can make cost-effective investment in energy efficiency, they are far more likely to take action.
  • From the interest we have seen so far we expect ESOS to benefit British business by helping companies to reduce overheads and increase competitiveness.

The UK?s Energy Saving Opportunity Scheme ESOS is a gold mine of opportunities for big business, the environment and the population that breathes the air. Measurement of critical energy throughputs is the beginning of the process. EcoVaro is standing by to help you convert your data to meaningful information.
