High-Water Mark
A high-water mark is a provision in hedge fund fee structures preventing the GP from charging performance fees until prior losses have been fully recouped. The high-water mark is the highest cumulative NAV the LP has previously seen; performance fees apply only on returns above this level. Protects LPs from paying double fees on the same upside.
The high-water mark structure exists to align GP and LP incentives. Without it, a fund losing 50% in year 1 and recovering 100% in year 2 (back to flat) would charge performance fees on the year-2 recovery — even though the LP made nothing over the two years. With high-water-mark, the recovery is performance-fee-free until the original peak is exceeded. This is widely considered the LP-fair structure and is now standard in the hedge fund industry.
The per-LP high-water mark can differ from the fund's overall high-water mark, particularly in funds where LPs invest at different times. An LP entering at peak NAV has a high-water mark equal to entry. An LP entering after a 30% drawdown has a high-water mark equal to entry NAV (the post-drawdown level), not the fund's pre-drawdown peak. New LPs effectively pay performance fees from a lower base than legacy LPs in the same fund.
The high-water mark interacts with crystallization timing. Most hedge funds 'crystallize' performance fees annually — the high-water mark resets at year-end based on actual NAV. Some funds use longer crystallization periods (multi-year), which is more LP-favorable. A fund with annual crystallization that underperforms in year 1 and outperforms in year 2 charges a performance fee in year 2 even though the cumulative two-year return is mediocre.
GP departures and fund liquidations create high-water-mark complications. When a successful GP loses key personnel and underperforms, LPs often redeem; the GP may close the fund and start a new one with a fresh high-water mark. This 'fresh start' problem is a structural critique of the hedge-fund industry — successful GPs are insulated from accumulated underperformance via fund-restart.
Synthetic hedge-fund LP positions should track the LP's high-water mark explicitly — distinct from the fund's reported NAV and from the original entry NAV. Performance-fee charges should fire only when current NAV exceeds the high-water mark. Underperformance scenarios should show no performance fees during recovery periods until prior losses are fully recouped.
Common pitfalls
- Computing performance fees on absolute returns rather than above-high-water-mark returns — overcharges LPs after drawdowns.
- Resetting the high-water mark at GP discretion — only annual crystallization with actual NAV-based reset is standard; mid-year resets violate the spirit of the structure.
- Aggregating LP high-water marks across different LPs — each LP has their own based on their entry NAV.
- Forgetting that closed-and-reopened funds typically reset the high-water mark — a known industry critique.
Examples
LP invests $10M at $10/unit. Year 1: NAV $11/unit (+10%). Performance fee: 20% × 10% × $10M = $200k charged. Year 2: NAV $9/unit (−18%). No performance fee (below high-water mark $11). Year 3: NAV $10/unit (+11% recovery). No performance fee (still below $11 high-water mark). Year 4: NAV $11.50/unit (+15%). Performance fee on excess above high-water mark: 20% × ($11.50 − $11)/$10 × position value ≈ $100k. Without high-water-mark protection, year 3's recovery would have triggered a performance fee on the 11% bounce.
