How do hedge fund fee structures work, and what is the high-water mark provision?

Hedge fund fee structures are more complex than mutual fund fees and are a frequently tested topic. Let's walk through the mechanics.

Standard Fee Structure (2 and 20):

• Management fee: 2% of assets under management (AUM), charged regardless of performance
• Incentive fee (performance fee): 20% of profits above a benchmark or hurdle

High-Water Mark (HWM): The high-water mark is the highest previous NAV that the fund achieved. The fund can only charge incentive fees on new profits above the high-water mark.

Example — Crestfield Global Macro Fund:

Starting AUM: $500 million

Year 1: Fund returns +15%

• Ending NAV (before fees): $575M
• Management fee: 2% x $500M =$10M
• Incentive fee: 20% x ($575M -$500M) = 20% x $75M =$15M
• NAV after fees: $575M -$10M - $15M = **$550M**
• New high-water mark: $550M

Year 2: Fund returns -10%

• Ending NAV (before fees): $550M x 0.90 =$495M
• Management fee: 2% x $550M =$11M
• Incentive fee: $0 (NAV below high-water mark)
• NAV after fees: $495M -$11M = $484M
• High-water mark remains: $550M

Year 3: Fund returns +20%

• Ending NAV (before fees): $484M x 1.20 =$580.8M
• Management fee: 2% x $484M =$9.68M
• Incentive fee: Only on gains above HWM: 20% x ($580.8M -$550M) = 20% x $30.8M = **$6.16M**
• NAV after fees: $580.8M -$9.68M - $6.16M = **$564.96M**
• New high-water mark: $564.96M

Key Observation: In Year 3, even though the fund gained 20% ($96.8M), the incentive fee is only calculated on the$30.8M above the high-water mark, not the full gain. The HWM protects investors from paying performance fees on recovered losses.

Hurdle Rate vs. High-Water Mark:

Feature	Hurdle Rate	High-Water Mark
Purpose	Minimum return before incentive fees	Prevents fees on loss recovery
Basis	Fixed rate (e.g., SOFR + 2%)	Previous peak NAV
Soft hurdle	Incentive fee on ALL gains once hurdle is exceeded	N/A
Hard hurdle	Incentive fee only on gains ABOVE the hurdle	N/A

Exam tip: CFA Level I loves multi-year fee calculation problems. Always track the high-water mark year by year. Remember: management fees are charged regardless of performance, but incentive fees require both positive returns AND exceeding the high-water mark.
