The waterfall architecture here is doing exactly what it was designed to do, which is the problem. An IRR-only promote hurdle is sponsor-friendly in short holds because IRR is time-sensitive in a way equity multiple is not. Annualize a clean 24-month exit and the IRR looks strong even when the LP walks away with 1.3x on committed capital. The equity multiple tells the actual dollar story, and if it is not in the promote trigger, it is not protecting you.
I read both before signing, and I want to see them working together. The structure that addresses this most directly is a dual-trigger promote: the sponsor does not earn the carry until the deal clears both an IRR hurdle and a minimum equity multiple, something in the 1.7x to 2.0x range depending on the hold and asset class. Either condition alone is incomplete. IRR without a multiple rewards early sales. A multiple without an IRR threshold rewards slow ones.
The risk you did not name is the decision-making asymmetry on exit timing. The GP controls when the asset goes to market. An IRR-only waterfall creates a structural incentive to sell early if a strong offer arrives, because a short hold inflates annualized returns and clears the promote faster. The LP has no operational control and, in most agreements, no approval right over a sale above a specified price. That incentive misalignment is baked into the doc before you wire a dollar.
I have also seen preferred return accrual language that interacts badly with early exit, where the pref has not had time to compound meaningfully, so the LP's preferred position is thinner than projected even when the promote triggers clean. Confirm how the pref accrual and distribution waterfall sequence around an ahead-of-schedule sale, not just how the promote calculates.
On your direct question: yes, I have walked away from a deal where the hurdle method changed the decision. The doc had IRR-only, no multiple floor, and a GP-controlled sale trigger with no LP consent right above a defined threshold.
What was the equity multiple floor, if any, written into the promote structure on this deal?
