Fee Structures

Management Fees and Performance Allocations, Explained

What the two layers of private fund compensation actually pay for, how high-water marks work, and the SEC threshold that determines who may be charged a performance fee at all.

Private fund compensation usually has two layers, and they do very different jobs. Confusing them is the single most common source of misunderstanding when investors compare managers.

The management fee pays for the lights

The management fee is an annual percentage of assets under management, typically accrued and charged monthly or quarterly. It funds the ongoing operation of the manager: research, systems, data, compliance, and staff. It is charged whether the fund is up or down, because those costs exist whether the fund is up or down.

The important thing to understand about management fees is their relationship to fund size. A fixed cost base spread across a small pool of assets consumes a larger percentage of that pool than the same cost base spread across a large one. This is why very small funds often show weaker returns net of fees in their earliest months, even where the underlying strategy performed as intended — a structural effect, not a judgment on the strategy.

The performance allocation pays for results

The second layer goes by several names — performance allocation, incentive allocation, carried interest, performance fee — and it is a share of the fund's profits rather than a share of its assets. An “80/20” arrangement means the investor retains 80 percent of the gains and the manager receives 20 percent.

The intent is alignment: the manager earns meaningfully only when investors do. The structure is not perfect — critics reasonably point out that it gives managers an asymmetric payoff, since they share in gains but not in losses — which is why the next mechanism exists.

High-water marks prevent paying twice for the same gain

A high-water mark records the highest value an investor's capital account has previously reached. The manager can only take a performance allocation on gains above that level.

An example makes it concrete. An investor's account rises from $100,000 to $120,000; the manager takes its share of that $20,000 gain, and the high-water mark is set at $120,000. The following period the account falls to $105,000. The period after, it recovers to $118,000. Despite that being a $13,000 gain in the period, no performance allocation is taken, because the account is still below its $120,000 high-water mark. The manager only participates again above $120,000.

Not every investor may be charged a performance fee

This is where regulation enters. Under the Investment Advisers Act, an adviser generally may not charge performance-based compensation unless the client is a qualified client as defined in Rule 205-3. The SEC adjusts the dollar thresholds for inflation every five years.

Effective 29 June 2026, a person qualifies if either:

• they have at least $1.4 million under management with the adviser immediately after entering the contract; or
• the adviser reasonably believes their net worth, alone or jointly with a spouse, exceeds $2.7 million, excluding the value of their primary residence.

These replaced the prior thresholds of $1.1 million and $2.2 million, which had been in place since 2021. The practical consequence is that funds charging a performance allocation must confirm qualified client status before accepting capital — and it is a separate, higher bar than accredited investor status, which many people assume is the only test that applies.

Comparing managers on fees, sensibly

Headline percentages are a poor basis for comparison on their own. Three questions get you much further:

1. What is the fee charged on? Net assets, gross assets, or committed capital? These produce materially different dollar amounts.
2. What expenses sit outside the management fee? Audit, administration, legal, and organisational costs are often borne by the fund on top of the fee. Ask what the total expense load has actually been.
3. Are reported returns net of everything? A return quoted net of management fee but gross of performance allocation and fund expenses is not comparable to one quoted net of all of them.

A manager who can answer all three plainly and without hedging is telling you something useful, quite apart from the numbers themselves.
