What a co-investment vehicle does
A co-investment vehicle lets selected investors invest alongside a primary fund, sponsor, or lead in a known opportunity. It can provide extra capacity when the main fund cannot or should not take the full allocation. The co-investors usually gain exposure to one asset through a separate SPV, limited partnership, or similar structure.
The structure is simple only at the diagram level. The manager still has to settle allocation, conflicts, economics, information, governance, expenses, asset ownership, investor eligibility, tax, reporting, and exit across the main fund and the co-investment vehicle.
When it fits
Co-investment may fit when an opportunity is larger than the fund's target position, concentration limits constrain the main vehicle, an LP has negotiated co-investment access, or the manager wants to bring strategic capital into a transaction.
It fits poorly when the main fund is being deprived of an investment it should receive, the extra allocation is not firm, the timeline cannot support a second close, or the vehicle's fixed costs make the net exposure unattractive.
Resolve allocation and conflicts first
| Decision | Evidence to preserve |
|---|---|
| Main-fund allocation | Policy, capacity analysis, investment approval |
| Co-investor selection | Eligibility and allocation rationale |
| Terms | Side-by-side comparison with the main fund |
| Expenses | Allocation method and invoices |
| Future rounds or exits | Follow-on and sale-allocation policy |
The governing documents and disclosures should explain why the opportunity is split, who may participate, whether the manager or affiliates invest, and how changed allocations will be handled. Apply the fund's allocation and conflict policies consistently. If the answer departs from policy, document the authority and investor disclosure.
Compare economics on the same asset
Co-investment is often described as carrying lower fees or carry than the main fund. Do not stop there. Add formation, administration, tax, audit support, banking, broken-deal expenses, transfers, and dissolution. Compare investor-level economics after the vehicle's full lifecycle costs.
State whether the main fund bears sourcing, diligence, legal, monitoring, or failed-transaction costs that benefit the co-investment vehicle. Define how shared invoices are allocated and approved. Related-party charging deserves explicit review.
Keep rights and information aligned
The primary fund or one holding entity may be the registered owner of rights that economically benefit both pools. Record which vehicle owns the security, which party exercises votes and information rights, how proceeds are allocated, and whether the co-investors receive the same economic exposure.
If the vehicles invest through separate instruments or at different times, compare price, seniority, preferences, information, pro rata rights, transfer restrictions, and exit treatment. “Alongside” should not hide materially different terms.
Operate two vehicles without mixing them
Maintain separate legal registers, bank activity, ledgers, capital accounts, investor reports, tax records, and approvals. Link them with a common transaction identifier, not by combining records. Cash should not move between vehicles without documented authority and accounting.
The manager needs one view of the relationship and separate authoritative records for each entity. The fund operations guide covers cross-entity controls, while the SPV launch guide covers the co-investment close.
Plan for follow-ons and exits
Before closing, decide whether the co-investment vehicle can or must participate in follow-ons, how a limited allocation will be divided, and what happens if some investors do not fund. Address partial sales, tenders, escrow, non-cash consideration, and different liquidity opportunities.
The distribution waterfall should match the governing documents and the asset-level proceeds. Reconcile the main fund and co-investment records to the same issuer or seller evidence.
A decision checklist
- Confirm the main fund's entitlement before offering co-investment.
- Document investor selection and allocation.
- Compare terms and rights across vehicles.
- Model all vehicle costs and shared expenses.
- Identify the legal holder and governance authority.
- Separate cash, books, registers, and approvals.
- Define follow-on and exit treatment.
- Keep a portable record through dissolution.
A co-investment vehicle works when it adds capacity without compromising the primary fund's mandate or creating an opaque second class of economics.
