In the world of private markets funds, the subscription premium, also known as the equalisation premium, is often presented as a purely technical mechanism, almost incidental. In reality, it is a structuring economic lever that directly shapes investors' entry point, the distribution of performance and fairness between generations of subscribers. This article explains how it works, its effects in feeder structures and the points of attention for advisers and investors.

When properly designed, the equalisation premium preserves the alignment of interests between investors.
When poorly calibrated or insufficiently explained, it can instead create real economic distortions, particularly in funds that remain open over long periods.
Subscription premium: the general mechanism in private markets funds
A private equity or private debt fund never invests its entire capital on day one. Investments are made gradually, as the management team identifies opportunities.
This raises a central question: how can investors who subscribe at different times during the fund's subscription period be treated fairly?
Without a corrective mechanism, an investor joining late would benefit from:
- investments that have already been made,
- part of the value potentially already created,
- without having tied up their capital or borne the initial risk.
The subscription premium, or equalisation premium, addresses precisely this issue.
Investors joining after the first closing pay a premium on top of their capital calls, designed to place them economically in the same position as the initial investors.
This subscription premium is generally calculated on the amounts already called, using a rate explicitly set out in the fund's legal documentation, most often close to the hurdle rate, and then pro-rated according to the time elapsed since the first closing.
Key takeaways
- In theory, the equalisation premium is a sound mechanism, institutional in nature and widely recognised as market best practice.
- This principle should nonetheless be tested against the economic reality of funds that remain open over a long period.
Equalisation premium: a structuring tool to erase timing gaps
In a fund open over a long period (18 to 24 months), which is now common, performance does not crystallise only at the end of the investment period. It builds up progressively, sometimes very early, from the first transactions.
The equalisation premium was designed precisely to erase the economic gaps created by successive entry points.
It places each investor, whenever they subscribe, in a comparable economic situation, as if they had joined the fund at launch.
In this logic, the asymmetries created by investors entering one after another are actively corrected, the impact of the J-curve borne by the first investors is offset, and the distribution of performance becomes fairer over time.
The longer the subscription period, the more decisive the economic role of the equalisation premium.
This balancing function is all the more essential when the fund continues to:
- invest actively,
- rebalance its portfolio,
- and create value throughout the entire opening period.
The equalisation premium fully plays its role as a fairness mechanism: it is designed to erase gaps and preserve the economic alignment between investors.
Funds of funds and feeders: when the subscription premium becomes critical
The subscription premium is particularly sensitive in funds of funds and master/feeder structures.
By design, the master fund applies its own subscription premium, the feeder fund applies its own, and the two must be perfectly consistent to avoid any distortion.
When they are not, a relative transfer of value can arise between the feeder's investors.
A key point that is too often underestimated.
Take a master fund and its feeder fund. If the master applies, for example, a subscription premium of 8%, while the feeder applies only 5%, the master keeps creating value throughout the fundraising period. This value is then partly absorbed by the feeder, without being fully re-invoiced to the investors who join the feeder later.
The gap is neither marginal nor purely technical. Over 18 to 24 months, it becomes economically tangible.
Impact of the subscription premium on investors in the feeder's first closing
An investor present from the feeder's first closing:
- fully bears the J-curve,
- ties up their capital earlier,
- assumes the initial uncertainty about the portfolio,
- without benefiting from any compensation mechanism vis-à-vis later entrants.
Meanwhile, the master fund keeps investing, unrealised performance grows, and new investors in the feeder pay for only part of it through an insufficient subscription premium.
There is therefore a genuine relative economic dilution to the detriment of the feeder's initial investors. This is neither theoretical nor ideological: it is the mechanical consequence of a structure that is not properly aligned.

Equalisation premium and the entry point of late investors
Conversely, investors joining the feeder later:
- access a fund that is already partly invested,
- benefit from better visibility on the portfolio,
- enter at a point when part of the value creation is already under way, without paying the full cost of that past performance.
Their economic entry point is objectively more favourable, with reduced asymmetric risk, a shallower J-curve and potentially smoother performance.
This is a purely economic observation. It involves no moral judgement and is not a matter of controversy.
Subscription premium, transparency and fiduciary responsibility
From a professional and fiduciary standpoint, the subscription premium cannot be treated as a mere technical detail. It has a direct impact on investors' comparative returns, on the perception of risk and on the quality of the information provided.
An equalisation premium that is poorly explained or insufficiently transparent raises a governance issue, weakens the comparability of performance and sends a negative signal to experienced investors.
Structuring in the service of net performance
At Private Corner, we believe structuring is never cosmetic.
Aligning the feeder's subscription premium with that of the underlying fund or funds means:
- following an institutional logic,
- protecting the initial investors,
- preserving, as far as possible, the real performance of the selected funds.
“Our conviction is simple: value is created in the funds, but it is preserved in the structuring, and in particular in the rigorous handling of the equalisation premium.”
— Estelle Dolla, President of Private Corner
Conclusion: a mechanism to explain, not to downplay
The subscription premium, or equalisation premium, is an indispensable fairness tool in private markets. But it is neither magic nor a perfect neutraliser, especially in multi-tier structures.
For financial advisers and investors alike, understanding it, questioning it and analysing its alignment between master fund, feeder and target funds is a core part of a rigorous approach to private markets.
In private markets more than anywhere else, structuring details make the difference between theoretical performance and the performance actually received.

FAQ – Equalisation premium and subscription premium
What is the equalisation premium in a private markets fund?
The equalisation premium, or subscription premium, is paid by investors who join a fund after its first closing. It places them economically in the same position as the initial investors, who tied up their capital earlier and bore the J-curve.
How is the subscription premium calculated?
It is generally calculated on the amounts already called, using a rate set out in the fund's legal documentation, most often close to the hurdle rate, and then pro-rated according to the time elapsed since the first closing.
Why is the equalisation premium critical in a feeder fund?
The master fund and the feeder fund each apply their own premium. If the rates are not consistent, part of the value created by the master is not re-invoiced to the feeder's incoming investors, creating a transfer of value to the detriment of the initial investors.
Who is penalised when the feeder's premium is lower than the master fund's?
The investors in the feeder's first closing. They fully bear the J-curve and the initial uncertainty, without sufficient compensation vis-à-vis later entrants, whose economic entry point is more favourable.
