High-Water Marks and Performance Fees

A hedge fund charges a 20% performance fee, standard for the industry. Without a safeguard, a fund could lose 20% one year, collect nothing (there's no profit to take a cut of), then gain back exactly 20% the next year and charge its investors a 20% fee on that recovery, even though the investor is still no better off than when they started, they've merely gotten back to where they were before ever paying anything. The high-water mark exists to stop exactly that: it requires the fund's value to exceed its previous highest level before any new performance fee can be charged.

How it plays out over a drawdown and recovery

Suppose an investor puts $1,000,000 into a fund with a 20% performance fee and a high-water mark provision.

Year 1: the fund loses 20%. Value falls to $800,000. No performance fee is charged, there's no gain. The high-water mark stays at $1,000,000, the highest value the account has ever reached.

Year 2: the fund gains 25%. Value rises from $800,000 to $1,000,000 (since $800{,}000 \times 1.25 = 1{,}000{,}000$). The fund is exactly back to its starting value and the investor has made no net money across the two years. Because the account has only reached its old high-water mark, not exceeded it, still no performance fee is charged.

Year 3: the fund gains a further 10%. Value rises from $1,000,000 to $1,100,000, a genuine new high, $100,000 above the prior high-water mark. Only now does a performance fee apply, and only on the $100,000 of gain above the mark: $100{,}000 \times 20\% = 20{,}000$, i.e. $20,000 in fees. The new high-water mark becomes $1,100,000.

Without the high-water mark provision, the manager would have collected a performance fee in both year 2 (on the "gain" from $800,000 back to $1,000,000) and year 3, despite the investor only ever being ahead by $100,000 across all three years combined.

What this means in practice

High-water marks are close to universal in hedge fund fee structures because investors simply won't accept paying performance fees on losses being recovered, it would mean paying twice for the same dollar of profit. The provision also shapes manager incentives in a specific, sometimes uncomfortable way: a fund sitting well below its high-water mark after a bad drawdown earns no performance fee until it fully recovers, which can push a struggling manager toward taking on more risk to climb back to the mark faster, or alternatively toward shutting the fund down and relaunching a new vehicle with a fresh high-water mark reset to the new, lower starting value.
