6 Reasons to stop using Excel for waterfall distribution calculations

It is no secret that most CFOs and other investment professionals are addicted to using Excel. Spreadsheets are the most available tool for many accounting and number-crunching tasks. But they are not without limitation, and when financial institutions become reliant on spreadsheets for more complex tasks, problems arise. A spreadsheet was for a long time the tool of choice to digitise something that was previously paper-based, but when it comes to today’s requirements of digitalization – can it cope?

Distribution waterfalls in the private equity world define the returns investors receive and are dictated by the provisions of Limited Partnership Agreements (LPAs). They form a critical step in the partnership between fund managers (GPs) and investors (LPs) and are often unique and complex in nature.

Before we delve into some of the reasons not to use Spreadsheets for calculating waterfalls, here’s some stats which underline the problem.

1. Inaccuracies

Bad calculations and errors in spreadsheets often go undetected and are then distributed and shared with partners and investors. One small mistake in a formula can have significant repercussions and lead to incorrect results which can get compounded over time. Troubleshooting errors in complex waterfall calculations can be time-consuming and challenging, not to mention the reputational damage and potential legal costs.  

2. Key person risk

Manual spreadsheets are created by individuals and not easily understood by everybody, which in turn prevents collaboration and consistency. They also increase the risk of dependency and problems when staff leave an organization. “Legacy” models can be a nightmare to understand if the creator leaves without sharing the information. This often leads to spreadsheets with multiple layers of logic, each built by different owners and making it even more complex to understand and review.

3. Security

Excel sheets can contain proprietary and sensitive data that should not be shared or fall into the wrong hands. Spreadsheets do not fall under the same scrutiny as IT projects, with versioning and other controls, and thus can become a security risk. Also, since Excel has long been a target for hackers the files themselves become a threat if shared.

4. Scale

As your business grows, using manual spreadsheets will limit your ability to scale and accurately track investment returns, catch-up, hurdle, fees, and other complex calculations. Even simple formulas need to be re-entered every single time a model is created and can be discovered to be wrong later on. The manual repetitiveness is not only boring and painful, but also a cause for undetected mistakes. Across a range of investments, each with its own terms and agreements, in different jurisdictions, can you realistically trust a spreadsheet to handle that complexity at scale?

5. Auditability

With the complexity of differing LPAs across a range of investments, can you trust Excel to handle the complexity and auditability, especially if the exposure to fees is considerable. Spreadsheets lack robust auditing features, making it difficult to trace and validate changes made to formulas and data. This lack of transparency can hinder the ability to ensure accuracy and accountability in complex calculations. Auditing spreadsheets is particularly challenging compared to an automated solution which can generate reports.

6. Lack of collaboration

Spreadsheets are fine for individuals, but as with key person risk, they are not designed for robust team collaboration and bring additional problems with version control, corrupted files, and ownership. They also help to perpetuate the problem of data silos within organizations, with data trapped in different worksheets which is not shared in one central repository.  

Automation for waterfall distribution calculations

Clearly the days of using Spreadsheets for waterfall calculations is coming to an end. Whilst spreadsheets can still play their part in the process, usually through data loading or reporting, they should not be used as the waterfall calculation engine at the heart of your process.
