What is the difference between a European and an American waterfall?

Last reviewed: 17 September 2026

The labels describe when the general partner starts sharing in profit. A whole of fund waterfall, commonly called European, runs the calculation across the fund, so limited partners generally receive their capital and preferred return across the whole fund before the general partner participates. A deal by deal waterfall, commonly called American, runs the calculation per realisation, so the general partner can participate earlier. Actual behaviour is set by the fund's own agreement, including any clawback provision.

Neither label is a legal term and neither describes a fixed set of numbers. They are shorthand for the level at which the calculation runs. Reading the distribution article of the specific limited partnership agreement is the only reliable way to know what a fund does.

The practical consequence is timing of general partner cash flow and the size of the risk that too much was paid too early. That risk is what a clawback addresses: an obligation to return excess distributions if, measured across the fund at the end, the split turns out to have favoured the general partner.

Limited partners typically read three things together: the level the waterfall runs at, the basis and rate of the preferred return, and the strength of the clawback, including whether it is secured and whether it is calculated after tax.

Frequently asked questions

Is one structure standard?

No. Both are widely used and hybrids are common, including deal by deal with interim clawback tests. Prevalence varies by strategy and by market, and any claim about a market standard split should be checked against the agreements you actually have.

What is a clawback?

An obligation on the general partner to return distributions that, measured across the fund at the end of its life, exceeded the agreed share of profit. Its practical value depends on whether it is secured, who is obliged, and whether it is computed before or after tax.

Does the preferred return compound?

It depends on the agreement. Whether it compounds, at what frequency, and on what base are all drafting choices, which is why we do not publish an indicative figure here.

How does Reuben AI help?

Distribution terms, realisations and investor level allocations sit alongside the deal record, so a waterfall run can be traced to the underlying evidence rather than reconstructed from a spreadsheet at quarter end.
