Distribution waterfall

Also called Waterfall, Distribution structure, Promote structure.

A distribution waterfall is the ordered set of tiers that determines how cash is split between limited and general partners. Each tier is filled completely before any money reaches the next one, and the general partner's share rises as it goes.

How it works

The structure exists to align incentives across an asymmetric partnership. Limited partners supply most of the capital and want their money back with a base return before anyone is rewarded for performance. The general partner supplies the work and wants a disproportionate share of the upside it creates. A waterfall encodes that bargain as an algorithm.

A conventional structure runs four tiers: return of capital, then the preferred return, then a general partner catch-up, then a residual split such as 80 to the limited partners and 20 to the general partner. Structures with multiple IRR hurdles add tiers, so the general partner's share might step from 20 percent above a 12 percent IRR to 30 percent above an 18 percent IRR and 40 percent above 22 percent.

Two structural choices dominate the outcome and both should be established before any modelling. European or whole-fund waterfalls test the hurdle across all capital before promote is paid; American or deal-by-deal waterfalls test each investment separately and pay promote earlier, usually with a clawback to protect limited partners if later deals disappoint. And IRR-based hurdles make the split depend on timing, while multiple-based hurdles do not, which is why many agreements require both to be met.

Worked example

A four-tier waterfall, worked through

Illustrative. $10,000,000 of limited partner capital, 8 percent cumulative compounded preferred return, five-year hold, full general partner catch-up to 20 percent, then an 80/20 residual split. Total distributions of $18,000,000.

Tier 1, return of capital to the LP$10,000,000
Tier 2, accrued preferred return to the LP$4,693,281
Tier 3, GP catch-up at 100%$1,173,320
Tier 4, residual 80/20LP $1,706,719, GP $426,680$2,133,399
Limited partner total$16,400,000
General partner total, and its share of profit$1,600,000, exactly 20% of the $8,000,000 profit

Every tier ties out and the catch-up does its job precisely: the general partner ends with 20 percent of all profit above return of capital, which is what a full catch-up is designed to produce.

Conventions worth knowing

  • Establish whether the hurdle is measured on IRR, on equity multiple, or on both. IRR-only hurdles can be cleared by an early partial sale in a way a multiple hurdle cannot.
  • Deal-by-deal promote without a clawback is a structural risk to limited partners, not a detail.

The common mistake

Assuming a residual split applies to all the profit

An 80/20 waterfall does not mean the general partner receives 20 percent of profit at every level. Below the preferred return it receives nothing beyond its pro rata share, and in the catch-up tier it may receive 100 percent. The general partner's realised share of profit is therefore a function of how much total profit there was, and on a deal that barely clears the pref it can be close to zero. The only way to know any partner's outcome is to run the actual tiers on the actual cash flows, in order.
