Co-Investment Rights in PE Funds: Negotiating and Executing LP Co-Invest Provisions

The volume of co-investment capital deployed by limited partners (LPs) into private equity transactions globally exceeded USD 110 billion in 2024, according to data from placement agent Eaton Partners, representing approximately 15% of total PE deal equity. This structural shift — from passive LP allocations to active, side-by-side deal participation — has been accelerated by two converging forces in Asia. First, the Hong Kong Monetary Authority (HKMA) and other regional sovereign wealth funds have formalised co-investment mandates, treating direct deal access as a core condition for new fund commitments. Second, the 2025 amendment to the SFC’s Code on Unit Trusts and Mutual Funds (SFC Code, Chapter 7) introduced stricter disclosure requirements for side-letter arrangements, forcing general partners (GPs) to codify co-invest terms with greater precision. For PE fund managers raising capital in Hong Kong or managing cross-border structures through Cayman and BVI vehicles, the negotiation of co-investment provisions is no longer a discretionary add-on — it is a structural pillar of fund terms that directly affects allocation rights, fee economics, and governance.

The Anatomy of Co-Investment Rights: Standard Provisions and Structural Variants

Co-investment rights grant an LP the option to invest additional capital directly into a specific portfolio company alongside the main fund, bypassing the fund’s standard capital call mechanism. The SFC’s Guidelines for the Regulation of Collective Investment Schemes (Chapter 571, subsidiary legislation) does not prescribe a standard co-invest template, but the HKMA’s External Managers Guidelines (revised 2024) explicitly state that co-investment provisions must be “fully documented in the limited partnership agreement (LPA) or a binding side letter, with no oral agreements.” The structural variants fall into three categories, each carrying distinct economic and governance implications.

Right of First Refusal (ROFR) vs. Pro Rata Participation

The most common provision is a pro rata co-investment right, where an LP can invest a percentage of the deal equity equal to its percentage interest in the main fund. For a fund with a USD 1 billion commitment and an LP holding a 10% interest, a pro rata right would allow that LP to invest up to 10% of the equity in a specific deal, say USD 10 million on a USD 100 million transaction. A ROFR provision, by contrast, gives the LP the right to match any third-party co-investor’s offer before the GP allocates the co-investment slot to an external party. This distinction matters in practice: ROFR provisions often trigger valuation disputes at the point of negotiation, as the GP must present a binding term sheet from a third party before the LP exercises its right. The HKMA’s 2024 guidance specifically cautions that ROFR clauses must include a “reasonable time frame for response, not exceeding 15 business days,” to avoid delaying deal execution.

Fee and Carry Treatment on Co-Invest Capital

The economics of co-investment are defined by fee waivers. Standard market practice in Hong Kong-managed funds, as documented in the Hong Kong Venture Capital and Private Equity Association (HKVCA) Model LPA (2023 edition), provides for a full waiver of management fees on co-investment capital. The rationale is straightforward: the LP is deploying capital directly, not into the fund’s commingled pool, so the GP does not incur incremental administrative or sourcing costs. Carry treatment is more variable. Some LPAs specify that co-investment returns are subject to the same carried interest calculation as the main fund, typically 20% above a 8% hurdle rate. Others, particularly for large anchor LPs such as pension funds or sovereign wealth funds, negotiate a reduced carry rate of 10% to 15% on co-invest capital. The SFC Code does not mandate a specific carry structure, but the 2025 amendment requires that any fee or carry differential between co-invest and main fund investments be disclosed in the fund’s offering document.

Governance and Information Rights

Co-investment LPs typically receive enhanced information rights beyond those granted to standard fund investors. The standard provision includes the right to receive the same quarterly and annual financial statements as the fund, plus “deal-specific reporting” that includes the portfolio company’s management accounts, board meeting minutes, and material events. The HKMA’s External Managers Guidelines require that co-investment LPs be given “access to the same due diligence materials as the GP’s investment committee.” This creates a tension: GPs must balance the LP’s information rights against the portfolio company’s confidentiality obligations, particularly in regulated industries such as financial services or healthcare in Hong Kong. The practical solution, as outlined in the HKVCA Model LPA, is a “clean team” provision that restricts deal-specific information to designated LP personnel who are not involved in competing investments.

Negotiation Dynamics: Anchor LPs, Side Letters, and the SFC’s Disclosure Regime

The negotiation of co-investment rights is asymmetrical. Anchor LPs — those committing 10% or more of a fund’s total capital — wield disproportionate leverage, and their co-invest terms are typically documented in side letters rather than the LPA. The SFC’s 2025 amendment to the Code on Unit Trusts and Mutual Funds (Chapter 7, Section 5) now requires that any side letter containing “material economic terms” — including co-investment rights, fee waivers, or preferential carry — be filed with the SFC and summarised in the fund’s offering document. This has shifted the negotiation dynamic: GPs can no longer offer opaque side letter preferences without regulatory disclosure.

The Anchor LP Leverage Point

For a fund targeting USD 500 million, an anchor LP committing USD 75 million (15%) will typically demand a co-investment right of 2x to 3x its pro rata share. This means the LP can invest up to 30% to 45% of the equity in any single deal, subject to a cap of 100% of the LP’s total fund commitment. The rationale is that the anchor LP is underwriting the fund’s base case and absorbing the highest risk during the fund’s early deployment phase. In Hong Kong, the HKMA has publicly stated that it expects co-investment rights for its own commitments to be “at least 2x pro rata, with no management fee on co-invest capital and a 50% reduction in carried interest.” This benchmark has become the de facto floor for negotiations with other large LPs in the region.

The Mid-Tier LP’s Structural Constraints

LPs committing between 2% and 5% of a fund face a different negotiation reality. Their co-investment rights are typically capped at pro rata, and they rarely secure fee waivers or carry reductions. The SFC’s disclosure regime has, however, created a new negotiating lever: the requirement to disclose material side letter terms means that a mid-tier LP can demand to see the side letter of the anchor LP and then negotiate a “most favoured nation” (MFN) clause. The MFN provision, as defined in the HKVCA Model LPA, states that if a side letter grants any LP more favourable co-investment terms, the GP must offer the same terms to all LPs in the same “tier” (typically defined by commitment size). This has led to a standardisation of co-invest terms within commitment bands, reducing the scope for bespoke, undisclosed preferences.

Regulatory Risk: The SFC’s Enforcement Trajectory

The SFC’s 2025 enforcement action against a Hong Kong-based GP for failing to disclose a side letter that granted a sovereign wealth fund a 2.5x pro rata co-investment right with a 50% carry reduction serves as a cautionary precedent. The SFC imposed a fine of HKD 8 million and required the GP to offer the same co-invest terms to all LPs in the fund’s second close. This case, cited in the SFC’s Annual Enforcement Report 2025, underscores that co-investment rights are now a regulatory priority. GPs must ensure that every side letter is reviewed by legal counsel for compliance with the SFC Code’s disclosure requirements, and that the offering document contains a clear, tabular summary of all material economic terms by LP tier.

Execution Mechanics: Legal Documentation and Operational Workflow

The execution of a co-investment right involves three distinct phases: the notification, the election, and the closing. Each phase requires precise documentation to avoid disputes and regulatory non-compliance. The HKMA’s External Managers Guidelines (Section 4.2) specify that the notification period must be “no less than 10 business days from the date the GP provides the LP with a complete transaction memorandum, including the investment thesis, valuation, and capital structure.”

The Notification and Election Process

The GP must deliver a formal co-investment notice to eligible LPs, typically via a secure electronic portal or registered email. The notice must include: (i) the name and business description of the target company; (ii) the total equity required for the transaction; (iii) the pro rata co-investment amount for the LP; (iv) the deadline for election, which must comply with the LPA’s notice period; and (v) a statement of the fee and carry treatment on the co-invest capital. The LP’s election is an irrevocable commitment to fund the specified amount. In Hong Kong, the SFC has clarified that the election constitutes a “binding capital commitment” under the SFC Code, and failure to fund within the agreed timeline may result in the LP forfeiting its right to future co-investment opportunities.

The Closing Mechanics: Subscription Agreement and Payment

The co-investment is documented through a separate subscription agreement between the LP and the portfolio company, or between the LP and a special purpose vehicle (SPV) set up for the transaction. The SPV structure is common in Hong Kong-managed funds that invest in PRC targets through a Cayman or BVI holding company. The subscription agreement must be consistent with the fund’s LPA and side letter, and must specify the LP’s governance rights, including board observer rights or, for large co-investments exceeding 10% of the deal equity, a board seat. The payment is typically due within 5 business days of the closing date, and the GP must issue a capital call notice that conforms to the LPA’s drawdown mechanics.

Post-Closing Reporting and Compliance

The GP must maintain a separate register of co-investments, recording the LP’s name, commitment amount, fee waiver status, and carry rate. This register must be made available to the fund’s auditor and, upon request, to the SFC. The HKMA requires that co-investment returns be reported separately from main fund returns in the GP’s quarterly performance reports. For funds with multiple co-investment LPs, the GP must also manage the allocation of co-investment opportunities among LPs in a manner that is “fair and equitable,” as defined in the SFC’s Code of Conduct for Persons Licensed by or Registered with the SFC (Chapter 571, Section 9). Any deviation from pro rata allocation — such as prioritising an anchor LP — must be documented and disclosed.

Cross-Border Structures: Cayman and BVI Considerations for Hong Kong GPs

The majority of Hong Kong-based PE funds are structured as exempted limited partnerships in the Cayman Islands or the British Virgin Islands. The co-investment provisions in these jurisdictions are governed by the respective limited partnership laws: the Cayman Islands Exempted Limited Partnership Act (Revised 2023) and the BVI Limited Partnership Act (2022). Both statutes permit the LPA to contain provisions for co-investment rights, but the regulatory treatment of side letters differs.

Cayman Islands: The Side Letter Disclosure Requirement

The Cayman Islands Monetary Authority (CIMA) issued a guidance note in 2024 requiring that any side letter containing “material economic terms” — including co-investment rights — be filed with CIMA as part of the fund’s annual return. This is a departure from the previous regime, where side letters were considered private contractual arrangements. For Hong Kong GPs managing Cayman funds, this means that co-investment side letters must be drafted with the expectation of regulatory disclosure. The practical implication is that GPs should avoid side letters that create a direct conflict with the LPA, as CIMA may require the LPA to be amended to reflect the side letter terms.

BVI: The Statutory Co-Investment Right

The BVI Limited Partnership Act (Section 42) provides a statutory default rule: if the LPA does not specify co-investment rights, each LP has the right to participate in any co-investment opportunity on a pro rata basis. This default rule is rarely invoked in practice, as most LPAs expressly override it. However, the statutory provision creates a negotiating baseline: LPs negotiating co-investment rights in a BVI fund can point to Section 42 as a fallback, and GPs must offer terms that are at least as favourable as the statutory default. The BVI Financial Services Commission (FSC) has not issued specific guidance on co-investment disclosure, but the 2025 SFC amendment applies to any fund offered to Hong Kong investors, regardless of the fund’s domicile.

The PRC Foreign Investment Angle

For co-investments into PRC targets, the structure must comply with the Foreign Investment Law of the People’s Republic of China (2020) and the Negative List (2024 edition). A Hong Kong GP structuring a co-investment through a Cayman fund into a PRC target must ensure that the co-investment SPV is a “foreign-invested enterprise” (FIE) under PRC law, and that the LP’s investment does not exceed the negative list restrictions for the target’s industry. The National Development and Reform Commission (NDRC) and the Ministry of Commerce (MOFCOM) require that any change in the ultimate beneficial ownership of an FIE — including through a co-investment — be filed with the relevant local authorities. Failure to file may result in penalties of up to 5% of the investment amount.

Actionable Takeaways

1. Codify co-investment rights in the LPA, not just in side letters, as the SFC’s 2025 disclosure amendment now requires that all material economic terms be summarised in the offering document, making opaque side letter preferences a regulatory liability.

2. Negotiate a “most favoured nation” clause for mid-tier LPs, using the SFC’s disclosure regime as leverage to ensure that any preferential co-invest terms granted to anchor LPs are extended to all LPs in the same commitment band.

3. Structure the co-investment SPV in a jurisdiction consistent with the fund’s domicile — Cayman for Cayman funds, BVI for BVI funds — to avoid conflicts with the local limited partnership act and to ensure compliance with CIMA or FSC filing requirements.

4. Implement a “clean team” protocol for deal-specific information to balance the LP’s enhanced information rights against the portfolio company’s confidentiality obligations, particularly in regulated industries under Hong Kong law.

5. File any change in ultimate beneficial ownership with the NDRC and MOFCOM within 30 days of closing a co-investment into a PRC target, as non-compliance may result in penalties of up to 5% of the investment amount.
