High-Water Mark
The highest NAV per unit a fund has reached and crystallized — performance fees apply only above this level, never on a recovery from a prior loss.
Definition
A high-water mark (HWM) is the highest net asset value (NAV) per unit or per share a fund has ever reached and locked in at a prior crystallization date. It acts as a running benchmark for performance fee purposes: a manager can only earn a performance fee on NAV gains that push the fund above its existing mark, never on gains that merely bring a previously loss-making fund back to where it once stood.
In practice this means a fund that loses money must first recover fully to its previous peak NAV per unit before any performance fee starts accruing again — commonly described as being underwater. The mechanic exists because, without it, a manager could earn a fee twice on the same dollar of gains: once when NAV first rose, and again after a loss and partial recovery, even though the investor's cumulative return over the full period could be flat or negative.
A high-water mark is typically set per investor, per series, or per share class rather than fund-wide, because investors who subscribe at different times enter at different NAVs per unit and therefore start with different marks. It commonly moves in only one direction — up — and only at a defined crystallization date, not continuously with every NAV tick.
Why it matters
Without a high-water mark, a fund could charge a performance fee on NAV volatility rather than on genuine cumulative gains — an investor could pay fees in a year the fund merely recovered a prior year's losses, even though their net position over both years hadn't improved.
For LPs evaluating a fund, the presence and mechanics of a high-water mark are one of the clearest signals of whether a fee structure is aligned with investor outcomes. It is close to standard market practice in institutional hedge fund terms, and its absence is commonly treated as a term worth asking about directly during due diligence.
Performance fee with a high-water mark
If NAV per unit sits at or below the mark, the max(0, …) term returns zero — no performance fee is owed until the fund recovers above its own prior peak.
A loss, then a recovery above the old mark
Take a fund with a 20% performance fee and no hurdle, starting at a NAV of $100.00 per unit — that is also its opening high-water mark. Over the next two periods, NAV falls to $85.00 and then recovers to $112.00.
The fee is charged only on the $12.00 gain above the old $100.00 mark ($112.00 − $100.00) — not on the full $27.00 rebound from the $85.00 low. The $15.00 recovery from $85.00 back up to the $100.00 mark is never fee-able; it is simply the investor getting back to even.
| Period | NAV per Unit | High-Water Mark | Fee Basis | Fee Charged (20%) |
|---|---|---|---|---|
| 1 | $100.00 | $100.00 | $0.00 — this NAV sets the opening mark | $0.00 |
| 2 | $85.00 | $100.00 | $0.00 — below the mark, no fee accrues | $0.00 |
| 3 | $112.00 | $100.00 → $112.00 | $12.00 ($112.00 − $100.00) | $2.40 |
Common mistakes
Treating a partial redemption as if it resets the high-water mark for an investor's remaining units — the mark should carry forward on the remaining balance, not snap back down to the current NAV.
Applying one fund-wide high-water mark when the fund actually runs multiple series or share classes tracked through series accounting — each series commonly needs its own mark, or early and late investors end up charged unevenly for the same gain.
Assuming crystallization frequency has no bearing on the mark — a manager who crystallizes quarterly locks in a new high-water mark four times a year, which can diverge meaningfully from a fund that crystallizes only annually.
Confusing a negotiated 'soft' high-water mark reset (typically paired with a lower go-forward fee rate, agreed with investors) with a mark that resets automatically — a soft reset is a deliberate contract renegotiation, not a default mechanic of the fee structure.
Believing a high-water mark limits how much a fund can lose — it only governs when a performance fee becomes payable again; it does no risk management on its own and offers investors no capital protection.
In practice
Crypto funds tend to see sharper NAV swings within a single quarter than traditional strategies, which makes the interaction between crystallization frequency and the high-water mark especially visible: a fund that crystallizes quarterly can start owing a performance fee again within one strong quarter of a drawdown, while a fund on an annual cycle stays fee-free until year-end even after the same recovery.
Funds that run series accounting for capital that entered at different NAVs typically track the high-water mark per series rather than per fund, so an investor who subscribed mid-drawdown is never charged a performance fee on a recovery that only brings the fund back to where it stood before they invested.

Questions, answered
What is a high-water mark?
A high-water mark is the highest net asset value per unit a fund has previously reached and crystallized. A manager can only charge a performance fee on gains above that level — not on gains that simply recover a prior loss.
Does the high-water mark ever reset?
Not automatically. A high-water mark generally only moves upward, when NAV per unit reaches a new high at a crystallization date. Some managers negotiate a 'soft' reset with investors — usually paired with a lower future fee rate — but that is a deliberate contract change, not a default mechanic.
Is the high-water mark the same for every investor in the fund?
Not necessarily. Funds that track series or share-class accounting because investors entered at different NAVs commonly maintain a separate high-water mark per series, so an investor who joined during a drawdown isn't charged a performance fee on gains that only bring the fund back to where it stood before they invested.
How does a high-water mark interact with a hurdle rate?
They work together, not as substitutes. A hurdle rate sets a minimum return the fund must clear before any performance fee accrues at all; the high-water mark separately ensures that fee is only charged on genuinely new gains, not on a recovery from a prior loss. A fund can have either, both, or neither.
