In practice
Set out in the distribution provisions of the LPA, this structure has been common in US buyout, venture and real estate funds and is rare in Europe. Terms vary: some versions require recovery of realized losses and write-downs on earlier deals before carry is paid, which brings them closer to a whole-fund test. It is often called deal-by-deal and contrasted with the European waterfall.
An example
Round numbers, not a real fundSay a fund sells its first company at a $30 million gain. Under a deal-by-deal waterfall the manager can take carry on that gain right away, subject to a later clawback.
Why it matters
Managers get paid sooner under it, which is why it usually comes with a clawback.
