8 Common mistakes we encounter with waterfall calculation models

Luke Hinchliffe

Waterfall calculations are used to determine the returns and fees of investments between partners and are based on pre-agreed terms. The proceeds earned are distributed via sequential steps in a cascading structure, hence the term ‘waterfall distribution’ which is commonly found in private equity.

Since building a platform that automates waterfall calculations, we frequently encounter mistakes in calculation models that have usually been created manually using spreadsheets. Since auditing spreadsheets is challenging, we often discuss these mistakes with our clients and how to address them using qashqade.  

Here’s a list of some of the most common errors we see in waterfall calculation models:

1. LP specific terms are applied to wrong LPs

In calculations of funds with many LPs, LPs with different side letter arrangements get mixed up and accounted for in the waterfall partially on non-applicable terms.

2. Reallocation of one LP’s proceeds

Despite the LPA stating that distributions are apportioned among the LPs pre-waterfall, in the calculations after every waterfall step (e.g., return of capital, preferred return) the still distributable amounts per LP are summed up and re-allocated again among the LPs based on various allocation keys.

3. Confusion about the GP’s role in the allocations

Payments in the waterfall that the GP receives as investor (LP or internal LP) and amounts that it receives in its capacity as fund / investment manager got commingled giving rise to rolled-forward calculation mistakes.

4. Multiple distributions cause the preferred return calculation to fail

Preferred return calculations that work well under the assumption of one single distribution (liquidation proceeds, NAV) may experience disturbances if many smaller distributions take place instead of one bullet payment only.

5. Unclear difference between compounding and IRR Hurdle

Waterfall calculations often mix up the preferred return calculation of annually compounded return and the internal rate of return (IRR) approaches and consider or fail to consider amounts paid to the LPs in steps following the preferred return as contributors to the attainment of the preferred return.

6. Double-counted contributions

In management fee waiver programs, the special contributions of LPs were double-counted and accounted for in the waterfall both as LP cost contributions and deemed GP contributions.

7. Unwanted dilutions

In a subsequent close, the equalization interest that incumbent LPs receive is considered as an amount that increases their unfunded commitment, even though this item should not have any impact either on commitments or on contributions.

8. Wrong timing of conditions

A consideration is omitted that while the preferred return calculation has to consider contributions and distributions on the very date of their occurrence, the gross and net IRR metrics have to be based on the month-end cash flow balances.

Automation for waterfall 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, they should not be used as the waterfall calculation engine at the heart of your process.
