Spreadsheet Risks in Banks

No other industry perhaps handles such large volumes of critical financial data more than the banking industry. For decades now, spreadsheets have become permanent fixtures in the front-line reporting tool sets of banks, providing organised information when and where needed.

But as banks enter into a period of heightened credit risks, elevated levels of fraud, and greater regulatory scrutiny, many are wondering if continued reliance on spreadsheets is a wise decision for banks today.

The downfall of Lehman Brothers which eventually led to its filing for Chapter 11 bankruptcy protection on September 15, 2008, served as a wake up call for many institutions across the globe to make a serious examination of their own risk management practices. But would these reforms include evaluating the security of user developed applications (UDAs), the most common of which are spreadsheets, and putting specific guidelines as to when they can – or cannot be – used?

Banks and Spreadsheet Use

Banks have been known to utilise spreadsheets systems for many critical functions because most personnel are well-acquainted with them, and the freedom of being able to develop customised reports without needing to consult with the IT department offers flexibility and convenience. In fact, more than having a way to do financial budgeting and analysing customer profitability, even loan officers and trade managers have become reliant on spreadsheets for risk management reporting and for making underwriting decisions.

But there are more than a few drawbacks to using spreadsheets for these tasks, and the sooner bank executives realise these, the sooner they can adopt better solutions.

General Limitations

Spreadsheets are far from being data base systems and yet more often than not, they are expected to act as such, with figures constantly added and formulas edited to produce the presumably right set of reports.

In addition, data integrity is always a cause for concern as most values in spreadsheets are entered as manual inputs. Even the mere misplacement of a comma or a negative sign, or an inadvertent ?edit? to a formula can also be a source of significant changes in the outcome.

Confidentiality risk is also another drawback of the use of spreadsheets in banks as these tools do not have adequate?access controls to limit access to only authorised individuals. Pertinent financial information that fall into the wrong hands can lead to a whole new set of problems including the possibility of fraud.

Risks in Trading

For trading transactions, spreadsheets can prove to be of immense use – but only for small market volumes. As trade volumes increase and the types vary, spreadsheets are no longer a viable solution and may likely become more of a hindrance, with calculations taking longer in the face of bigger transaction amounts and growing transaction data.

And in trading, there is always the need for rigorous computational functions. Computing for the Value at Risk (VaR) for large portfolios for instance, is simply way beyond the capabilities of spreadsheets. Banks that persist in using them are increasing the risk of loss on those portfolios. Or, they can be opening up?opportunities for fraud?as Allied Irish Bank (in the case of John Rusnak – $690 million) learned the hard way.

Risks in Underwriting

Bankers who use spreadsheets as their main source of information for underwriting procedures also face certain limitations. Loan transactions require that borrowers? financial data be centralised and easily accessible to risk officers and lending officers involved in making decisions. With spreadsheets, there is no simple and secure way of doing that. Information can be pulled from different sources – individual tax returns, corporate tax documents, partnership documents, audited financial statements – hence there is difficulty in verifying that these reports adhere to underwriting policies.

Spreadsheet control and monitoring

Financial institutions which are having difficulty weaning themselves from the convenience and simplicity that spreadsheets offer are looking for possible control solutions. Essentially, they want to find ways that allow them to continue using these UDAs and yet somehow eliminate the?spreadsheet risks?and limitations involved.

Still, the debate goes back and forth on whether adequate control measures can be implemented on spreadsheets so that that the risks are mitigated. Many services have come forward to herald innovative solutions for better spreadsheet management. But at the end of the day, there really is no guarantee that such solutions would suffice.

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.

Reduce Cost and Improve Productivity

Whether the economy is in a downturn or not, management will always aim for a more cost effective IT solution. If your current IT infrastructure is hurting your profitability, our expertise is both ‘tested and proven”.? Also “bleeding edge” solutions in the industry will enable us to find inexpensive alternatives for you.

For instance, have you started to wonder whether having a constantly growing number of servers, many of which are underutilised, is really the norm? Well, that used to be the case. However, with the advent of virtualisation and replication, that expensive exercise is steadily becoming a thing of the past.

By implementing solutions powered by these two technologies, organisations can now manage excess storage capacities and hardware resources by performing simpler processes at lesser costs. In addition to that, using the same pair of technologies, companies can also decrease the downtime suffered during maintenance and upgrades.

Thus, at the end of the day, not only do companies stand to reduce expenditures, they can also boost revenues as a result of increased productivity time.

Do we still have other IT solutions that tackle a different set of problems but arrive at the same outcome, i.e. reduced costs + improved productivity = higher profits? You bet we do.

Basically, this is how we’ll help your company arrive at the same winning formula:

  • Provide insights as to where and when changes have to be made. Oftentimes, initiatives to reduce cost and improve productivity are not preceded by the appropriate study especially as with regards to their impact on all departments in the organisation. This usually results in unnecessary duplication of resources, a sure way to increase costs instead.
  • Consolidate and automate. We’ll work within your budget in finding ways to consolidate your applications, hardware, storage, databases, and processes. Then we’ll integrate automation practices to simplify management and maintenance of all these assets. This will substantially free not only your IT infrastructure but also your IT staff, giving them more opportunities to innovate.
  • Create an innovative environment. One of the benefits you gain in having room to innovate is the potential to discover new ways to drive costs even further. A fraction of your savings can then be used to develop even better IT solutions, thus creating a productive cycle: IT solutions > savings and innovation > better IT solutions. Our role is to help you harness your potentials to keep that cycle running.
  • Work to reduce carbon footprint in all your procedures. By ensuring that energy consumption is brought to a minimum in every step you take, you can rest assured that costs have only one way to go – down. Check out our Energy Management Software ecoVaro.

How SOA can help Transformation

Undoubtedly, today’s business leaders face myriad challenges ranging from fierce market competition to increasing market unpredictability. In addition, the modern consumer is more informed and in control of what, where and how they purchase. Couple these challenges with effects of globalization, and you will appreciate that need for business transformation is more of a necessity than a privilege.

As recent business trends show, top companies are characterized by organizational and operational agility. Instead of being shaken by rapid technological changes and aftershocks associated with market changes, they are actually invigorated by these trends. In order to survive in these turbulent times, business leaders are opting to implement corporate transformation initiatives to develop leaner, more agile and productive operations. In line with this, service oriented architecture (SOA) has emerged as an essential IT transformation approach for implementing sustainable business agility.

By definition, service oriented architecture is a set of principles and techniques for developing and designing software in form of business functionalities. SOA allows users to compile together large parts of functionality to create ad hoc service software entirely from the template software. This is why it is preferred by CIOs that are looking to develop business agility. It breaks down business operations into functional components (referred to as services) that can be easily and economically merged and reused in applicable scenarios to meet evolving business needs. This enhances overall efficiency, and improves organizational interconnectivity.

SOA identifies shortcomings of traditional IT transformation approaches that were framed in monolithic and vertical silos all dependent on isolated business units. The current business environment requires that individual business units should be capable of supporting multiple types of users, multiple communication channels and multiple lines of business. In addition, it has to be flexible enough to adapt to changing market needs. In case one is running a global business enterprise, SOA-enabled business transformation can assist in achieving sustainable agility and productivity through a globally integrated IT platform. SOA realizes its IT and business benefits by adopting a design and analyzing methodology when developing services. In this sense a service consists of an independent business unit of functionality that is only available through a defined interface. Services can either be in the form of nano-enterprises or mega-enterprises.

Furthermore, with SOA an organization can adopt a holistic approach to solve a problem. This is because the business has more control over its functions. SOA frees the organization from constraints attributed to having a rigid single use application that is intricately meshed into a fragmented information technology infrastructure. Companies that have adopted service oriented architecture as their IT transformation approach, can easily repurpose, reorganize and rescale services on demand in order to develop new business processes that are adaptable to changes in the business environment. In addition, it enables companies to upgrade and enhance their existing systems without incurring huge costs associated with ‘rip and replace’ IT projects.

In summary, SOA can be termed as the cornerstone of modern IT transformation initiatives. If properly implemented great benefits and a sharp competitive advantage can be achieved. SOA assists in transforming existing disparate and unconnected processes and applications into reusable services; creating an avenue where services can be rapidly reassembled and developed to support market changes.
