Hong Kong Open-Ended Fund Companies (OFCs): Structure, Advantages, and Regulatory Requirements

Introduction

The Open-Ended Fund Company (OFC) is a corporate fund vehicle introduced in Hong Kong in 2018 and substantially enhanced since, designed to provide the flexibility of a unit trust within a corporate structure. Since the inception of the OFC regime, Hong Kong has seen significant growth in OFC registrations, with the vehicle gaining traction among both retail and institutional fund managers seeking an onshore Hong Kong fund structure.

This article provides a comprehensive overview of the OFC regime — its structural features, regulatory requirements, tax treatment, the re-domiciliation mechanism for overseas funds, and the practical considerations fund managers should assess when evaluating the OFC as a fund vehicle.

What Is an OFC?

An OFC is a form of company incorporated in Hong Kong under the Companies (Open-Ended Fund Companies) Ordinance. Unlike a conventional Hong Kong company, an OFC is specifically designed to function as a collective investment scheme: it issues and redeems shares at net asset value (NAV), and its share capital must at all times equal its net assets.

Key structural features of the OFC include:

Variable capital: Unlike a conventional company with a fixed or minimum share capital, an OFC's share capital varies continuously as shares are issued and redeemed — the defining characteristic that makes it suitable as an open-ended investment fund.

Sub-fund structure: An OFC may establish one or more sub-funds, each with its own investment objectives, assets, and liabilities. Sub-fund assets and liabilities are ring-fenced from each other (umbrella segregation), meaning that the creditors of one sub-fund have no recourse to the assets of another.

Corporate form: As a company, an OFC is a recognised legal entity under Hong Kong law, capable of entering contracts, owning assets, and bringing or defending legal proceedings in its own name.

Directors and investment manager: The OFC is managed by a board of directors, but investment management functions must be delegated to a licensed or registered fund manager under the Securities and Futures Ordinance (SFO). The investment manager bears primary responsibility for the day-to-day management of the OFC's assets.

Types of OFCs

Public OFCs

Public OFCs are authorised by the Securities and Futures Commission (SFC) for offering to the retail public in Hong Kong. They must comply with the SFC's Code on Open-Ended Fund Companies (OFC Code), which prescribes detailed requirements on investment scope, redemption frequency, valuation, disclosure, and governance.

Private OFCs

Private OFCs are not authorised for public offering and are available only to professional investors (as defined in the SFO). Private OFCs enjoy considerably greater flexibility in investment strategy and governance, and are subject to a lighter regulatory touch compared to public OFCs. They are particularly attractive for hedge funds, private equity vehicles, and family office investment structures.

Governance and Regulatory Requirements

Directors

An OFC must have at least two directors, at least one of whom must be independent of the investment manager (and any custodian). Directors of OFCs are subject to fiduciary duties broadly analogous to those applicable to directors of conventional Hong Kong companies, and must act in the best interests of the OFC and its shareholders.

For public OFCs, additional requirements apply with respect to director qualifications and the independence requirements for the compliance function.

Custodian

All OFCs — whether public or private — must appoint a custodian to hold the OFC's assets in custody. The custodian must be an entity regulated for custodial activities in Hong Kong (or a comparable overseas entity approved by the SFC). The custodian's role is to safeguard assets, verify NAV calculations, and provide an independent check on the investment manager.

Investment Manager

The investment manager must be licensed or registered with the SFC under the SFO for the relevant regulated activities. For most OFCs, this means the investment manager must hold a Type 9 (asset management) licence or Type 4 (advising on securities) licence, depending on the nature of the managed assets.

Registration and Ongoing Compliance

OFCs are registered with the Companies Registry rather than incorporated through the standard company incorporation process. Private OFCs must also be registered with the SFC. Ongoing compliance obligations include:

• Annual audited accounts (to be prepared in accordance with internationally recognised accounting standards such as HKFRS or IFRS)
• Filing of annual returns with the Companies Registry
• Notification to the SFC and Companies Registry of material changes (e.g., change of investment manager, new sub-funds, amendments to the instrument of incorporation)
• Compliance with AML/CFT obligations, with primary responsibility resting on the investment manager

Tax Treatment of OFCs

The tax treatment of the OFC is one of its most compelling features. Subject to meeting the qualifying conditions, OFCs benefit from a comprehensive profits tax exemption under the Inland Revenue Ordinance (IRO).

Profits Tax Exemption

The OFC profits tax exemption — enacted as part of the OFC regime — exempts qualifying transactions carried out by or on behalf of an OFC from profits tax. Qualifying transactions include transactions in stocks, shares, debentures, bonds, and other securities, as well as futures contracts and foreign exchange contracts.

This exemption is particularly valuable for OFCs investing in Hong Kong-sourced income, which would otherwise be subject to profits tax at the standard rate. The exemption puts the OFC on a par with investment funds domiciled in offshore jurisdictions such as the Cayman Islands, which have historically benefited from zero-tax treatment.

Stamp Duty

Transfers of shares in an OFC (as opposed to in its underlying portfolio) are exempt from Hong Kong stamp duty. This facilitates secondary market liquidity in OFC shares without the friction of stamp duty costs.

Fund Manager Incentive

The carried interest tax concession available in Hong Kong (which provides reduced tax treatment for carried interest received by qualifying fund managers from qualifying funds) is available in respect of OFCs, aligning the OFC with the tax incentives already available for other fund structures such as limited partnerships.

Re-Domiciliation of Overseas Funds to OFC

A significant feature of the OFC regime is the re-domiciliation mechanism, which allows overseas corporate funds to migrate to Hong Kong and re-register as OFCs. This mechanism is designed to attract established funds currently domiciled in the Cayman Islands, BVI, Luxembourg, or other jurisdictions to establish a Hong Kong presence.

The re-domiciliation process involves:

• Approval from the relevant overseas regulators or courts for the fund to cease to be incorporated in the overseas jurisdiction
• Application to the Companies Registry and SFC (for private OFCs) for registration as a Hong Kong OFC
• Continuation of the fund's legal and contractual relationships without interruption — a key advantage is that fund documents, investor agreements, and investment portfolio positions continue in the re-domiciled entity without the need for a formal transfer

Re-domiciliation provides a pathway for fund managers who wish to consolidate their fund operations in Hong Kong, take advantage of the OFC tax regime, and signal a commitment to Hong Kong as a primary domicile for their fund business.

Comparison with Other Hong Kong Fund Vehicles

OFC vs. Unit Trust

The unit trust has historically been the dominant vehicle for retail collective investment schemes in Hong Kong. The OFC offers several advantages over the unit trust: corporate form (enabling cleaner governance and legal entity status), the sub-fund structure with statutory segregation, and greater flexibility in accepting non-cash subscriptions.

OFC vs. Limited Partnership Fund (LPF)

The Limited Partnership Fund (LPF) was introduced in 2020 for private equity and closed-ended funds. The OFC is better suited to open-ended, liquid strategies requiring frequent NAV calculations and redemption facilities. The LPF is typically preferred for illiquid asset strategies (private equity, real estate, infrastructure) where a fixed term and capital commitment model is more appropriate.

OFC vs. Cayman Islands Fund

The Cayman Islands exempted company and Cayman limited partnership remain dominant globally, particularly for institutional investors who are familiar with Cayman fund documentation. The OFC's principal competitive advantages over the Cayman structure are: a Hong Kong legal framework (familiar to China-focused investors), the profits tax exemption (directly comparable to Cayman zero-tax treatment), and the ability to market to Hong Kong and Mainland China investors under the Stock Connect and Mutual Recognition of Funds (MRF) framework.

OFC Under the Mutual Recognition of Funds (MRF) Framework

Hong Kong OFCs may be eligible for recognition and distribution in Mainland China under the MRF framework, which allows qualifying Hong Kong-domiciled public funds to be offered to retail investors in China. The MRF framework covers publicly authorised OFCs that meet SFC and China Securities Regulatory Commission (CSRC) requirements, including minimum asset size, track record, and investment scope conditions.

Access to the China retail market via MRF is a significant strategic advantage for Hong Kong-domiciled public OFCs, differentiating them from purely offshore structures that lack equivalent access.

Practical Considerations for Fund Managers

Fund managers considering the OFC structure should evaluate:

Investor base and distribution: Public OFCs targeting Hong Kong retail investors or seeking MRF access benefit most from the OFC structure. Private OFCs are better suited for institutional and family office investor bases.

Investment strategy: The OFC is most suitable for liquid, open-ended strategies. Illiquid or closed-ended strategies are better served by the LPF or conventional limited partnership structures.

Service provider ecosystem: The OFC requires a regulated investment manager, custodian, and auditor. Managers should assess the availability of suitable service providers in Hong Kong and build relationships with experienced OFC specialists.

Re-domiciliation vs. fresh launch: For managers with existing offshore funds, the re-domiciliation mechanism offers a streamlined path to Hong Kong registration. For new fund launches, the OFC can be incorporated from scratch with appropriate legal documentation.
