JV Waterfall Interview Questions: Pref, Promote, Catch-Up, and Worked Math

JV waterfall questions separate people who memorized "80/20 above an 8% pref" from people who can allocate a distribution. REPE interviews love waterfalls because the math is concrete and the economics are how sponsors get paid. This guide covers the tiers, catch-up, common variants, worked intuition, and how to answer under time.

What a waterfall is

A waterfall is the rule set for splitting cash between LP (limited partner) and GP (general partner / sponsor) as money comes out of a deal or fund. Order matters. Accruals matter. "Promote" is the GP's disproportionate share of profits after hurdles.

A common deal-level tier structure

Exact terms vary wildly. Always take the prompt's hurdles over a memorized "standard."

Preferred return mechanics

Pref is usually an annualized rate on contributed capital (or outstanding capital). Cumulative pref accrues if unpaid. Non-cumulative may not.

Interviewers will ask what happens if the deal sells late. Accrued cumulative pref becomes a larger use of proceeds before promote, dragging common / GP economics.

Catch-up, explained simply

After LP receives capital + pref, a 100% GP catch-up (common teaching case) means the next dollars go to the GP until the GP has received 20% of the profits above returned capital (for a 20% promote). Then the split goes 80/20.

Without catch-up, the GP may never reach the full promote economics on a short waterfall path. With catch-up, the GP "catches up" faster after the pref.

American vs European (fund context)

In deal-level REPE JV interviews, you may not need fund waterfall jargon. In PE fund economics interviews, you will. Know which frame you are in.

Worked mini-example (illustrative)

Assume:

• LP capital $80, GP capital $20 (80/20 ownership of capital)
• Single exit distribution $150 after full hold
• 8% cumulative pref to LP simplified as $24 accrued for the example
• 20% promote with 100% GP catch-up after pref

Teaching walk (simplified; real models track period-by-period):

1. Return capital: LP $80, GP $20 → $50 profit left ($150 − $100)
2. Pay LP pref $24 → $26 profit left
3. Catch-up: GP needs 20% of profits above capital. Profits above capital so far recognized depend on definition in the docs; in many teaching cases catch-up brings GP to 20% of profits before residual split
4. Residual split 80/20

You will not always get a clean number set in interviews. What they want is the tier logic and which unpaid balances accrue.

GP promote share applies to profits above hurdles, not to returned capital.

Interview prompts and model answers

"Walk me through a JV waterfall."
"Capital back first, then preferred return to the LP, then any GP catch-up, then residual promote split like 80/20. I track accrued pref if cumulative and unpaid."

"What is a promote?"
"The GP's extra share of profits after hurdles, compensation for structuring and managing the deal beyond pro rata ownership."

"What is catch-up?"
"A tier that accelerates distributions to the GP after the pref so the GP reaches the agreed promote percentage of profits before the ongoing split."

"American vs European waterfall?"
"American can pay promote deal by deal; European typically requires fund-level capital return and pref before promote. Clawbacks matter more when promote is paid early."

Modeling checklist for tests

Common mistakes

Practice drills

1. Allocate a single exit distribution through four tiers on paper
2. Increase hold by two years and recompute cumulative pref drag
3. Toggle catch-up on/off and explain who benefits
4. Explain American vs European in 40 seconds
5. Build a Meridian-style waterfall case and narrate each tier from the sheet

Practice on SheetRank

Meridian-style JV waterfall deals exist to make tier math muscle memory. After each run, close the laptop and restate who got paid in what order. That is the interview.
