What should an investor verify first?

Whether the fund uses a European (whole-fund) or American (deal-by-deal) waterfall structure.

Which documents matter most?

The PPM's waterfall structure clause and any clawback provision under an American structure.

What is the main downside to test?

A manager collecting carry on an early win under an American waterfall before other positions' outcomes are known.

How should the final decision be made?

Confirm a clawback provision exists if the fund uses an American, deal-by-deal waterfall structure.

European vs American Waterfall

Urvashi L1 min read

Understanding the Return Path

A European (whole-fund) waterfall calculates carried interest only after all invested capital across the entire fund has been returned to investors. An American (deal-by-deal) waterfall can pay the manager carry on a single successful deal even while other fund positions remain unrealised or impaired.

Reading Waterfalls, Distributions and Exit Timing

A European waterfall is generally more investor-favorable, since the manager only earns carry after the whole fund has returned capital, aligning their incentive with overall fund performance rather than any single early win. An American waterfall can pay the manager carry earlier, sometimes before it's clear whether the fund overall will be profitable.

Where Liquidity Expectations Break

The common failure is not checking which structure applies before committing, and later being surprised that a manager collected meaningful carry on an early successful exit even as the fund's other positions later underperformed — a scenario only possible under an American waterfall.

Making the Cash-Flow Decision

Before committing, confirm which waterfall structure the fund uses, and if it is an American (deal-by-deal) structure, check whether a clawback provision exists requiring the manager to return excess carry if the fund's overall performance later falls short.

A European waterfall aligns manager incentive with whole-fund performance; an American waterfall requires a clawback provision to achieve similar alignment — confirm which applies and whether that protection exists.

Key takeaways

European waterfalls calculate carry only after all fund capital is returned — generally more investor-favorable.
American waterfalls can pay carry on individual successful deals before the whole fund's outcome is clear.
Under an American structure, check whether a clawback provision protects investors if later performance falls short.
Confirm which waterfall structure applies before committing — the difference is economically meaningful.
