Private Equity Co-Investment in Hong Kong: Legal Framework, Documentation, and Key Considerations

Introduction

Co-investment has become an increasingly important feature of the private equity landscape in Hong Kong and across Asia. As institutional investors — including sovereign wealth funds, pension funds, endowments, and family offices — seek to reduce fee drag and gain direct exposure to specific transactions, leading private equity managers have responded by offering co-investment opportunities alongside their flagship funds.

From the fund manager's perspective, co-investment provides additional capital for larger deals, deepens relationships with key limited partners (LPs), and enhances competitiveness in deal markets. From the investor's perspective, co-investment offers fee-efficient, targeted exposure to individual portfolio companies, often with reduced or zero management fees and carried interest.

This article examines the legal framework for co-investment arrangements in Hong Kong, the documentation that governs them, regulatory considerations, and the key practical issues that parties should address.

What Is Co-Investment?

Co-investment refers to an arrangement where a limited partner (or another approved investor) invests directly alongside a private equity fund in a specific portfolio company transaction, in addition to their commitment to the fund. The co-investor acquires a direct equity or debt interest in the portfolio company (or in a special purpose vehicle (SPV) that holds such an interest), as opposed to an indirect interest through the fund.

Co-investment may take several forms:

LP co-investment rights: Certain LPs negotiate co-investment rights in the fund's limited partnership agreement (LPA) or a side letter, entitling them to be offered co-investment opportunities on future deals above a specified size threshold.

Direct co-investment: The fund manager sources additional capital from co-investors on a deal-by-deal basis, without a prior commitment from the co-investor.

Co-investment vehicles: A dedicated SPV or co-investment fund is established for each deal, into which both the flagship fund and co-investors contribute capital. This structure provides a clean legal separation between the co-investment and the main fund.

Separate managed accounts (SMAs): Certain large institutional investors establish managed accounts with a fund manager, under which the manager has authority to invest the SMA's capital alongside the flagship fund, effectively creating a customised co-investment vehicle.

Co-Investment Rights in Fund Documentation

LPA Provisions

The most common basis for co-investment rights is the limited partnership agreement of the flagship fund. LPA co-investment provisions typically address:

• The category of LPs eligible for co-investment opportunities (often limited to LPs above a minimum commitment threshold)
• The circumstances in which co-investment opportunities must (or may) be offered — e.g., deals above a specified transaction size, or where the fund's investment constraints prevent it from taking the full investment
• The allocation methodology where multiple LPs seek to co-invest and the available co-investment amount is oversubscribed
• The timeline for LPs to accept or decline co-investment opportunities
• Whether co-investment carries economics comparable to the flagship fund (i.e., the same terms regarding fees and carry) or preferential terms

Side Letters

In practice, co-investment rights for large anchor LPs or strategic investors are often contained in side letters negotiated at the time of fundraising, rather than in the LPA itself. Side letter co-investment provisions may grant more favourable rights than those available to the broader LP base, including priority allocation rights, expanded eligibility criteria, or carry-free co-investment.

Side letters are confidential between the fund manager and the relevant LP, though most-favoured-nation (MFN) provisions in other LPs' side letters may trigger disclosure obligations if better terms are given to other LPs.

Co-Investment Documentation

Co-Investment Agreement

Once a co-investment opportunity is offered and accepted, the parties typically enter into a co-investment agreement (or subscription agreement) that documents the terms of the co-investor's participation in the specific deal. Key provisions include:

Capital commitment and drawdown: The co-investor's total capital commitment, the timeline for funding (often on very short notice, given private equity deal timelines), and the consequences of failure to fund.

Governance rights: Whether the co-investor has any board representation or observer rights at the portfolio company level, and how voting on key decisions (e.g., exit, restructuring) is coordinated between the flagship fund and co-investors.

Transfer restrictions: Restrictions on the co-investor's ability to transfer their interest, including lock-up periods, right of first refusal (ROFR), and tag-along and drag-along rights.

Exit coordination: Provisions ensuring that co-investors exit alongside the flagship fund (or within a specified period thereafter) and that the mechanics of the exit (sale process, pricing) are handled consistently.

Information rights: The scope of financial and operational information to which the co-investor is entitled in relation to the portfolio company and the co-investment vehicle.

Fees and expenses: Whether management fees, monitoring fees, transaction fees, or carried interest apply to the co-investment, and who bears deal expenses (including aborted deal expenses) if the transaction does not complete.

SPV Documentation

Where co-investment is structured through a dedicated SPV, additional documentation is required, including:

• Constitution documents of the SPV (articles of association or partnership agreement)
• Shareholders' or partnership agreement governing the relationship between the flagship fund and co-investors within the SPV
• Subscription agreement for the SPV
• Security or guarantee documents if the SPV requires leverage

Regulatory Considerations in Hong Kong

SFC Licensing

Fund managers who offer co-investment opportunities to Hong Kong investors must consider whether their activities constitute regulated activities under the Securities and Futures Ordinance (SFO). Specifically:

• Advising co-investors on the merits of a specific investment opportunity may constitute Type 4 (advising on securities) regulated activity, requiring an SFC licence
• Managing co-investment SPVs or vehicles may constitute Type 9 (asset management) regulated activity
• Soliciting or arranging co-investments may constitute Type 1 (dealing in securities) regulated activity depending on the structure

Many fund managers address this through their existing SFC licences, but the specific scope of regulated activity should be confirmed with legal advisers for each co-investment structure.

Securities Offering Rules

Offering interests in co-investment vehicles to Hong Kong investors constitutes an offer of investments under the SFO. Unless an exemption applies, the offer must be made through a licensed intermediary and may require compliance with SFC's authorisation requirements or private placement safe harbours (e.g., limited offer to professional investors).

AML/CFT Obligations

Fund managers managing co-investment vehicles for Hong Kong investors remain subject to AML/CFT obligations under AMLO, including customer due diligence on co-investors and ongoing monitoring of their source of funds.

Tax Structuring for Co-Investment

Hong Kong Tax Profile

Hong Kong does not levy capital gains tax, inheritance tax, or withholding tax on dividends (with limited exceptions). This makes Hong Kong an attractive co-investment base for regional investors. Co-investment vehicles structured as Hong Kong companies or limited partnerships may also benefit from Hong Kong's bilateral tax treaty network and the offshore gains exemption from profits tax.

SPV Jurisdiction Selection

The choice of SPV jurisdiction for a co-investment vehicle depends on the deal structure, the portfolio company's jurisdiction, the co-investors' tax profiles, and the exit strategy. Common SPV jurisdictions for Asia-Pacific co-investments include the Cayman Islands, BVI, Singapore, and Mauritius, each offering different combinations of treaty access, tax neutrality, and regulatory environment.

Carry and Fee Economics

Where co-investment vehicles involve performance-related economics (e.g., a carried interest for the manager or GP entity), the tax treatment of carry must be considered in the relevant jurisdiction. Hong Kong's carried interest tax concession for qualifying carried interest received by qualifying employees or service providers of funds may apply in appropriate circumstances.

Key Issues for Co-Investors

Adverse selection risk: Co-investors must assess whether they are being offered the best deals or residual capital needs on challenging transactions. Understanding the manager's allocation policy and track record in co-investment is essential.

Speed of execution: Private equity transactions move quickly. Co-investors must be prepared to make investment decisions on compressed timelines, with limited due diligence access. Establishing pre-approved frameworks and decision-making processes for co-investment can reduce execution risk.

Information asymmetry: The fund manager has significantly more information about the portfolio company than the co-investor. Negotiating adequate due diligence access, rep-and-warranty coverage, and ongoing information rights is critical.

Exit alignment: Co-investors need comfort that their exit interests are aligned with those of the flagship fund. Tag-along rights and drag-along rights in the co-investment agreement are essential protections.

Governance and influence: Co-investors in large transactions may seek board seats or observer rights to monitor their investment. The extent to which these are available depends on the deal size, the co-investor's capital contribution, and the fund manager's willingness to share governance influence with co-investors.

Key Issues for Fund Managers

Conflicts of interest: Allocation of deal flow between the flagship fund and co-investors must be governed by clear, transparent policies to avoid conflicts. The SFC and other regulators expect managers to treat LPs fairly in the allocation of investment opportunities.

Confidentiality: Co-investors who receive confidential deal information must be bound by robust confidentiality undertakings, particularly where the deal involves a listed company or sensitive commercial information.

Liability exposure: Fund managers should ensure that their co-investment arrangements include appropriate limitation of liability provisions, and that their E&O and D&O insurance coverage extends to co-investment activities.
