Co-Investment Rights in Private Funds Explained

Co-investment rights give a limited partner (LP) the option to invest directly in a specific deal alongside the main fund, on top of the capital already committed to that fund. The LP typically invests through a separate vehicle set up for that one deal, and the arrangement often comes with lower fees than the main fund charges, because the manager is not sourcing or managing a diversified portfolio for that slice of capital. Co-investment is not automatic and not guaranteed — it depends on what rights, if any, are written into the fund's governing documents, and on the manager choosing to offer it for a given deal.

For anyone evaluating a private fund or a tokenized structure built on top of one, co-investment terms are worth understanding on their own, separate from the headline return figures a deal might show.

What Are Co-Investment Rights?

A standard private fund pools capital from many LPs and invests it across a portfolio of deals chosen by the manager (the general partner, or GP). An LP's exposure to any single deal is a slice of that pooled portfolio, sized by the fund's own allocation rules.

Co-investment works differently. When the GP identifies a deal that is larger than the main fund wants to hold on its own — or one where the GP wants to bring in extra capital without diluting other positions — it can invite some LPs to invest additional capital directly into that one deal, alongside the fund but through a separate co-investment vehicle. The LP ends up with two things: its normal pro-rata slice of the deal through the main fund, and a larger, concentrated position through the co-investment vehicle.

The right to be offered co-investment opportunities, if it exists at all, is typically set out in the fund's limited partnership agreement or side letter. It is a right to be considered, not a guarantee of allocation — GPs generally retain discretion over which LPs get invited and how much capital each is allocated, especially when demand for a co-investment opportunity exceeds the amount available.

Why Funds Offer Co-Investment Alongside the Main Fund

GPs offer co-investment for a mix of reasons that mostly serve the fund's own construction, not just LP preference.

• Deal size exceeds the fund's target concentration. Most funds cap how much of total committed capital can go into a single position. A large opportunity may need outside capital to be completed without breaching that cap.
• Relationship and fundraising incentives. Offering co-investment to larger or longer-standing LPs is a way to strengthen the relationship ahead of the fund's next fundraise.
• Speed and certainty of capital. A co-investment pool of known, pre-vetted LPs can close faster than sourcing a new syndicate partner for a time-sensitive deal.
• Fee economics for the GP. Co-investment vehicles are usually lower-fee for the LP, but they still generate some fee and carry income for the GP on capital the main fund could not otherwise deploy into that single position.

None of these reasons are negative for LPs on their own, but they explain why co-investment access tends to concentrate with a fund's largest or earliest investors rather than being offered evenly.

Fees and Terms: How Co-Investment Differs From the Main Fund

The fee and term structure of a co-investment vehicle is usually negotiated separately from the main fund, and it commonly looks different in a few specific ways.

The fee discount is the headline attraction, but it should not be read on its own. A lower fee on a concentrated single-deal position is not the same trade as a standard fee on a diversified portfolio — the fee savings and the added concentration risk both need to be weighed together, not just the first one.

What to Check Before Accepting a Co-Investment Opportunity

Because a co-investment allocation is a separate decision from the original fund commitment, it deserves its own review rather than being treated as an extension of trust already placed in the manager.

1. What is the underlying asset, borrower, or company? Co-investment concentrates exposure into one position, so the underwriting quality of that specific deal matters more than the manager's overall track record.
2. What are the fees and carried interest on this vehicle specifically? Confirm the terms in writing rather than assuming they match the main fund.
3. How much time is given to decide? Co-investment windows are often short, which limits how much independent diligence an LP can realistically complete.
4. What governance and reporting rights apply to the co-investment vehicle? These can be lighter than the main fund's, since co-investment vehicles are sometimes structured as simpler special-purpose entities. See what an SPV structure is for how these vehicles are typically built.
5. What is the exit path for this specific position? A co-investment in an illiquid asset carries its own exit timeline, which may not match the main fund's expected exit for its own slice of the same deal.
6. How does this affect overall portfolio concentration? An LP with capital across several funds run by the same GP, plus co-investment positions, can end up more concentrated in a handful of underlying names than the headline fund diversification suggests.

Risks and Limitations

Co-investment is a different risk shape than a standard fund commitment, not a strictly better one.

• Concentration risk. A single deal that underperforms affects the co-investment position far more than it would affect a diversified fund slice.
• Adverse selection. Deals offered for co-investment are not necessarily a fund's best opportunities; some GPs offer co-investment specifically because a deal is larger or riskier than the fund wants to hold alone.
• Compressed diligence time. Short decision windows can mean less time to review documents, valuation assumptions, and structure than an LP would normally take before committing capital.
• Uneven access. Co-investment rights, where they exist, often favor larger or longer-relationship LPs, so smaller investors in the same fund may see fewer or no opportunities.
• Governance gaps. A co-investment vehicle's reporting and consent rights can be lighter than the main fund's, which matters if something goes wrong with the deal.

None of this makes co-investment inherently unsuitable — it is a standard feature of many private fund structures, including some that sit behind tokenized RWA products. The point is that the fee discount is only one part of the trade, and it should be weighed against concentration, timing, and governance before an allocation is accepted. RWA structures that pool investors sometimes use related mechanics — a master-feeder structure or a parallel fund — to route different investor types into the same underlying deal, which is worth understanding alongside co-investment if a product references either term.

FAQ

Do all LPs in a private fund get co-investment rights?

No. Co-investment access is usually discretionary and tends to concentrate with a fund's largest or longest-standing LPs, unless the fund's governing documents specifically guarantee pro-rata co-investment rights to all investors. Check the fund's limited partnership agreement or side letters to see whether any right exists, and for whom.

Are co-investment fees always lower than the main fund?

Often, but not always. Management fees on co-investment vehicles are commonly reduced or waived, but carried interest may or may not be reduced, and terms vary by GP and by deal — the only reliable way to know is to check the specific co-investment vehicle's agreement rather than assume it matches the main fund.

Is co-investment riskier than investing through the main fund?

It carries different risk, mainly concentration risk, since capital goes into a single deal rather than a diversified portfolio. A co-investment in a strong deal can outperform the diversified fund slice, but a weak one has no other positions to offset it, so the position-level risk is higher even when the fee is lower.

Can I say no to a co-investment offer without affecting my main fund position?

Generally yes. Co-investment is typically structured as a separate, optional decision through its own vehicle, and declining an invitation does not usually change the terms of an LP's existing commitment to the main fund. Confirm this in the specific fund's documents, since terms can vary.
