For anchor limited partners committing nine-figure tickets to Vietnam and Southeast Asia-focused private equity and venture funds, co-investment rights have become a standard, and often decisive, negotiating point in the side letter. Alongside most-favored-nation protection, fee offsets, and information rights, co-investment rights let an LP deploy additional capital directly into a portfolio company alongside the fund, typically on reduced or no management fee and carried interest.
For general partners raising capital in a competitive Vietnam market, offering well-structured co-investment rights is frequently what closes an anchor commitment — but the drafting, governance, and deal-by-deal execution of those rights raise issues that are easy to underestimate until a live deal is on the table.

1. Why Co-Investment Rights Matter in Vietnam-Focused Fund Investing
Vietnam-focused funds compete for anchor capital against a wider Southeast Asia opportunity set, and limited partners writing large checks increasingly treat co-investment rights as part of the price of admission rather than a bonus. For an LP, the appeal is straightforward: co-investment allows exposure to specific, underwritten deals without paying full fund-level economics on the incremental capital, while deepening the relationship with the general partner and giving the LP’s own investment team direct deal experience in a market where local execution knowledge is scarce.
For GPs, offering co-investment rights solves a different problem: it lets the fund pursue larger checks than its committed capital or concentration limits would otherwise allow, without forcing a hard choice between deal size and portfolio diversification. In Vietnam, where attractive control or significant-minority opportunities in sectors such as renewable energy, logistics, consumer, and financial services often require tickets above what a mid-sized fund can commit alone, co-investment capacity is frequently the mechanism that lets the GP compete for the deal at all.
Who Negotiates Co-Investment Rights
In practice, co-investment rights are negotiated almost exclusively by anchor and cornerstone LPs — typically those committing above a threshold set relative to fund size, such as the greater of a fixed dollar amount or a percentage of total commitments. Sovereign wealth funds, development finance institutions, and large institutional allocators active in Vietnam routinely condition their commitment on securing a side letter with co-investment rights, reflecting both their bargaining power and their internal mandate to generate direct deal exposure alongside fund commitments.
2. Anatomy of a Side Letter: Negotiating Leverage for Anchor LPs
A side letter is a bilateral agreement between the fund’s general partner and a specific limited partner that modifies or supplements the terms of the limited partnership agreement as applied to that LP, without amending the LPA itself. Side letters are the vehicle through which co-investment rights, MFN protection, excuse rights, key-person provisions, and reporting commitments are typically documented, and they sit alongside — but legally subordinate to — the main fund documents.
The Institutional Limited Partners Association (ILPA) has published principles and model side letter terms that most institutional LPs now reference as a baseline during negotiation, even where a fund’s documents predate those standards. Anchor LPs negotiating in Vietnam-focused funds increasingly benchmark their asks against ILPA’s framework, which has shifted market norms toward more standardized, less idiosyncratic side letter terms across the region.
Key Terms Anchor LPs Request in Side Letters
Beyond co-investment rights, a typical anchor side letter in this market addresses excuse and exclusion rights tied to conflicts of interest or regulatory restrictions, key-person provisions tied to named investment professionals, notice and consent rights over material fund amendments, confidentiality carve-outs for the LP’s own regulatory or public-disclosure obligations, and — critically — most-favored-nation treatment relative to other LPs of similar or smaller size.
Each of these interacts with co-investment rights: an excuse right, for example, may need to extend to co-investment opportunities as well as fund-level deals.
Side Letter Negotiation Timing in the Fundraising Process
Side letter negotiation typically runs in parallel with the LPA negotiation during the fund’s first and subsequent closings, with anchor LPs using their early-close commitment as leverage to extract more favorable terms than later closers will receive. Because co-investment rights often reference specific thresholds (minimum deal size, sector exclusions, holding period alignment), LPs that negotiate early in the fundraising cycle have more room to shape those thresholds before they become market precedent for the rest of the LP base.
3. Most-Favored-Nation Clauses: Mechanics and Negotiation Tactics
A most-favored-nation clause gives an LP the right to be notified of, and in most cases to elect, more favorable terms granted to other LPs in side letters, subject to exceptions the fund negotiates for genuinely differentiated circumstances (regulatory status, sovereign immunity, strategic relationship value). MFN clauses are the mechanism that keeps co-investment rights and other side letter terms from becoming a race to see which LP has the most leverage at any given moment in the fundraising.
In Vietnam-focused funds, where the LP base often blends regional institutional investors, development finance institutions, and family offices with very different negotiating postures, MFN protection is particularly important: an anchor LP that negotiated hard on co-investment rights wants assurance that a later, equally sized LP will not quietly obtain broader rights without the first LP being offered the same terms.
MFN Clauses and the Disclosure Mechanism
MFN rights are only as good as the disclosure process behind them. Most funds now run a formal MFN election process after the final closing, circulating a summary of side letter terms (often in redacted or categorized form to preserve confidentiality) and giving each electing LP a window to select applicable provisions.
Anchor LPs should confirm, at negotiation stage, exactly how and when this disclosure process will occur, since a vague or informal MFN mechanism can leave co-investment rights and other benefits effectively unenforceable in practice.
Limits and Carve-Outs to MFN Protection
GPs typically carve out from MFN scope: terms tied to an LP’s specific regulatory status (tax exemption confirmations, sovereign immunity language), terms that reflect genuinely different commitment sizes or timing, and sometimes co-investment allocation priority itself, on the basis that allocation priority reflects relationship and capacity considerations rather than a term that should flow automatically to every similarly sized LP.
Anchor LPs should scrutinize any carve-out that would allow the GP to exclude co-investment rights from MFN scope altogether, since this can quietly undermine the value of the MFN clause for the single term anchor LPs often care about most.
4. Economics of Co-Investment: Fee Offsets, Carry, and Alignment
The economic terms attached to co-investment rights vary widely across Vietnam and Southeast Asia-focused funds, but several structures have become market standard. Fully offset co-investment — no management fee, no carried interest on the co-investment tranche — remains common for anchor LPs with significant fund commitments, reflecting the view that the LP is effectively subsidizing the GP’s ability to pursue larger deals rather than receiving a discretionary favor.
Reduced-fee co-investment, where the LP pays a lower management fee (commonly half the fund-level rate) and reduced or tiered carry, is more common for co-investment rights extended to mid-sized LPs or where the GP’s co-investment vehicle requires separate administration costs that need to be recovered. A smaller number of funds charge full fund-level economics on co-investment, usually reserved for opportunistic allocations offered to LPs without a contractual co-investment right.
Fee Offset Structures for Co-Investment Rights
Fee offset mechanics should specify, with precision, which fees are waived (management fee only, or management fee and carry), over what period, and whether the offset applies to the co-investment vehicle’s own organizational and operating expenses. LPs negotiating co-investment rights should also confirm whether follow-on co-investment in the same portfolio company carries the same offset terms as the initial investment, since GPs sometimes treat follow-ons as a separate allocation decision with different economics.
Carry and Promote Treatment on Co-Investment Deals
Where carried interest applies to co-investment, LPs should clarify whether it is calculated on a deal-by-deal basis (American waterfall) or alongside fund-level carry (European waterfall), and whether any clawback obligation on the GP’s carried interest from the main fund extends to carry earned on co-investment. Misalignment here can leave an LP economically worse off on a successful co-investment than the headline fee offset would suggest.
| Feature | Fund-Level Investment | Co-Investment (Typical Anchor LP Terms) |
|---|---|---|
| Management fee | Full rate (commonly 1.5%–2.0% of committed capital) | Often waived or reduced to 0%–1.0% |
| Carried interest | Standard 20% over hurdle, fund-level waterfall | Often waived, reduced, or deal-by-deal |
| Diversification | Spread across full portfolio | Concentrated in a single target company |
| Deal selection control | None — GP discretion | LP elects in/out per opportunity |
| Due diligence access | Fund-level reporting only | Deal-specific materials, often compressed timeline |
| Governance rights | LPA-level only | May include side-car board observer or consent rights |
5. Information Rights vs. Confidentiality: Managing the Tension
Co-investment rights are only exercisable if the LP receives enough information, early enough, to assess the opportunity — yet that same information is typically the fund’s and the target company’s most sensitive commercial and financial data, often subject to confidentiality undertakings the GP has given the target or its existing shareholders. This tension sits at the center of most co-investment negotiations and frequently resurfaces mid-deal, not just at side letter drafting stage.
LPs with genuine co-investment rights typically negotiate a defined information package — investment memorandum, financial model, key due diligence findings — triggered automatically once the GP decides to offer the opportunity for co-investment, alongside a standstill or confidentiality undertaking from the LP that mirrors what the GP itself has agreed with the target. Without this structure, GPs can quietly dilute co-investment rights by offering opportunities late, with incomplete information, or on compressed decision timelines that make meaningful diligence impossible.
Information Rights Anchor LPs Negotiate
Beyond deal-specific disclosure, anchor LPs typically negotiate standing information rights covering portfolio company financial performance, material adverse developments, regulatory or litigation exposure, and valuation methodology for quarterly reporting — all of which inform whether and how aggressively the LP exercises its co-investment rights on future opportunities. These standing rights should be drafted to survive even where the LP declines a specific co-investment, since declining one deal should not forfeit the broader information flow that supports future decisions.
6. Deal-by-Deal Execution: Timeline Challenges in Vietnamese Target Companies
The gap between a well-drafted co-investment right on paper and a co-investment that actually closes is often widest in Vietnam, where deal execution timelines face structural friction that side letters rarely anticipate in enough detail. GPs typically commit to offering co-investment opportunities with a defined election window — commonly 5 to 15 business days — but Vietnamese target companies frequently present diligence and regulatory complexities that make this window unrealistic for an LP conducting independent review.
Land use rights verification, foreign ownership ratio confirmation across conditional business sectors, and corporate licensing history checks at the provincial Department of Planning and Investment level routinely take longer than the headline election window contemplated in side letters, particularly for LPs without an existing on-the-ground legal and tax advisory relationship in Vietnam.
Due Diligence Compression in Vietnamese Deal Processes
Because the GP has usually already run full-scope due diligence before offering the co-investment, LPs exercising co-investment rights are frequently working from the GP’s diligence materials rather than commissioning independent work within the election window.
This is workable where the LP trusts the GP’s due diligence provider and scope, but anchor LPs increasingly negotiate a right to commission limited confirmatory diligence — particularly on land use title, corporate structure, and tax exposure — even within a compressed timeline, rather than relying entirely on the GP’s findings.
Regulatory and Foreign Ownership Timing Constraints
Where the target operates in a sector subject to foreign ownership limits or conditional market access, the co-investment vehicle’s own capital structure may need separate regulatory clearance or Investment Registration Certificate amendment before closing — a process that can take weeks and does not compress to match a fund’s internal election timeline. LPs and GPs negotiating co-investment rights in regulated sectors should build realistic longstop dates into the side letter rather than defaulting to the generic election window used for unregulated sectors.
7. Governance and Approval Mechanics for Co-Investment Rights
Most co-investment structures route the LP’s participation through a dedicated special purpose vehicle alongside, or parallel to, the main fund’s investment vehicle, rather than direct LP ownership of target company shares. This affects governance: co-investing LPs typically do not receive direct board seats but may negotiate observer rights, information parity with the fund’s board representative, and consent rights over specific matters such as further dilutive issuances or related-party transactions.
Internal Approval Alignment Between GP and LP
A frequently underestimated execution risk is timeline mismatch between the GP’s internal investment committee process and the LP’s own internal approval chain for co-investment rights — which, for institutional LPs, often requires a separate credit or investment committee sign-off distinct from the original fund commitment approval. GPs and LPs that map out each other’s approval timelines during side letter negotiation, rather than discovering the mismatch mid-deal, significantly reduce the risk of a co-investment opportunity lapsing before approval completes.
8. Fund-Level Investing vs. Co-Investment: A Comparative Framework
LPs evaluating whether to prioritize co-investment rights over simply increasing their fund commitment should weigh the comparison across several dimensions beyond headline fee economics: concentration risk, the LP’s own capacity to conduct or absorb deal-specific diligence on a compressed timeline, and the opportunity cost of capital held in reserve for co-investment calls that may or may not materialize during the fund’s investment period.
In practice, the LPs that extract the most value from co-investment rights in Vietnam-focused funds are those with dedicated internal resources — legal, tax, and sector expertise — able to turn around a meaningful co-investment decision within the negotiated election window, rather than LPs that negotiated the right as a headline term without the internal capability to exercise it when a real opportunity arrives.
9. Drafting Considerations for GPs and LPs
Several drafting practices consistently reduce disputes and execution friction around co-investment rights in this market. First, define “co-investment opportunity” precisely — by minimum deal size, sector, and holding period — rather than leaving it to GP discretion on a deal-by-deal basis, since vague definitions are the most common source of later disagreement about whether a right was triggered at all.
Second, align the election window with realistic Vietnamese execution timelines rather than a generic market-standard period borrowed from other jurisdictions, and build in an extension mechanism tied to specific regulatory or diligence milestones rather than a fixed hard deadline.
Third, cross-reference co-investment rights explicitly with the MFN clause, the information rights provisions, and any excuse rights, since these terms interact constantly in practice and drafting them in isolation creates gaps that only surface once a live deal is underway.
For a broader structuring review of fund documents and side letter terms, see IVLF Advisors’ investment finance advisory services, and for related guidance on cross-border capital structuring, our investment finance practice page outlines the firm’s broader fund and transaction advisory work.
Finally, both sides benefit from referencing recognized market standards such as the ILPA best practices guidance on side letters and co-investment, which reduces negotiation friction by anchoring discussion in terms both institutional LPs and experienced GPs already recognize, rather than negotiating every provision from a blank page.
Negotiation Checklist for Anchor LPs
Before signing, an anchor LP should confirm that the side letter and the fund documents work together. In Vietnam private equity, where deal flow is concentrated in a small number of sponsors, the LP information rights package is often the first item traded away in negotiation, even though it is the one that lets the LP monitor whether co-investment allocations are being made fairly.
A short checklist helps: confirm the allocation policy, the fee offset formula, the MFN election window and the scope of LP information rights, then compare each against the fund’s confidentiality regime.
Frequently Asked Questions
What are co-investment rights in a private equity fund?
Co-investment rights let a limited partner invest directly in a specific portfolio company alongside the fund, in addition to its fund commitment, typically on reduced or waived fees and carry compared with fund-level terms.
Who typically receives co-investment rights in Vietnam-focused funds?
Anchor and cornerstone LPs committing above a defined threshold relative to fund size most commonly negotiate co-investment rights, reflecting their negotiating leverage and internal mandate for direct deal exposure.
How does a most-favored-nation clause interact with co-investment rights?
An MFN clause lets an LP elect more favorable side letter terms granted to other similarly sized LPs, which can include broader or better-priced co-investment rights, subject to negotiated carve-outs.
Why are co-investment timelines often tighter in Vietnam than other markets?
Land use verification, foreign ownership confirmation, and provincial licensing checks frequently extend beyond standard election windows, requiring realistic longstop dates in the side letter.
Are co-investment rights legally binding, or discretionary?
This depends entirely on drafting. A contractual co-investment right obligates the GP to offer qualifying opportunities, while a “co-investment opportunity” framed as discretionary gives the GP latitude the LP cannot enforce.
LPs and GPs preparing to negotiate or exercise co-investment rights in a Vietnam-focused fund should begin by reviewing their existing side letter and LPA language against current market practice before the next closing or live deal opportunity makes renegotiation impractical.
