The Family Business Diversification Strategy in a Family Constitution: Governance for Cross-Industry Investment

The 2025-2026 fiscal year has crystallised a structural tension for Hong Kong’s family-controlled business groups: the HKEX’s enhanced Listing Rules Chapter 18C for Specialist Technology Companies, effective 31 March 2023 and now fully tested in market practice, have widened the IPO pathway for single-family-office-backed ventures, while the SFC’s revised Code of Conduct for Sponsors (published in the Gazette on 15 December 2024) imposes stricter due diligence obligations on sponsors when a family’s cross-industry holdings create potential conflicts of interest. Simultaneously, the Hong Kong Monetary Authority’s 2025 Banking Stability Report (released 28 March 2025) noted that family offices now account for 14.7% of total private banking assets under management in Hong Kong, up from 11.2% in 2022. These converging forces mean that a family constitution — once a document focused solely on succession and shareholding — must now serve as the governance backbone for diversification into unrelated industries. Without a codified strategy for cross-industry investment embedded in the constitution, a family risks either regulatory friction during a listing or, worse, the erosion of family cohesion as disparate business units pull in conflicting directions.

The Governance Gap in Multi-Industry Family Holdings

The typical Hong Kong family business begins as a single-industry entity — property development, manufacturing, or trading — and accumulates surplus capital over one or two generations. The 2024 KPMG-HKICPA Family Office Survey reported that 68% of Hong Kong single-family offices with assets above USD 100 million have invested in at least three unrelated sectors, with the most common combinations being real estate, financial services, and healthcare. This pattern creates a governance problem that a standard shareholders’ agreement or trust deed does not address: how does the family decide which new industries to enter, at what capital commitment, and under what exit criteria?

Hong Kong’s Companies Ordinance (Cap. 622) provides the statutory framework for board duties, but it does not mandate a diversification policy. Section 465 requires directors to act in good faith and in the best interests of the company, but when a family holding company owns a property subsidiary, a fintech venture, and a biotech startup, the “best interests” of each entity may diverge. A family constitution that codifies a diversification strategy bridges this gap by establishing a pre-agreed framework for capital allocation across industries, reducing the risk of ad hoc decisions driven by the most persuasive family member.

The Role of a Family Investment Committee

The constitution should create a Family Investment Committee (FIC) with a defined mandate to approve new industry entries above a materiality threshold. The threshold should be expressed as a percentage of total family net worth — for example, any single investment exceeding 5% of consolidated family assets, as reported in the annual family balance sheet prepared in accordance with HKICPA standards, requires FIC approval. This structure mirrors the HKEX Listing Rules Chapter 14 requirement for discloseable transactions, where a 5% threshold triggers notification. The FIC should include at least one independent external member with sector expertise, a practice recommended by the SFC’s 2023 Consultation Paper on Corporate Governance of Listed Issuers.

A real-world example is the Lee family of Henderson Land Development, which codified its diversification into hospitality and data centres through a family council resolution in 2019, later formalised in the family constitution. The result was a 23.4% contribution to group revenue from non-property segments by FY2024, according to the company’s annual report. The constitution did not dictate the specific industries — that would be too rigid — but it established the governance process for evaluating them.

Alignment with the Family Office’s Investment Mandate

The family constitution must align with the investment mandate of the family office, whether that office is regulated under the SFC’s Type 9 (asset management) licence or operates as an unregulated single-family office. The HKMA’s 2025 circular on “Governance Standards for Family Offices” (Circular No. 05/2025, issued 10 January 2025) explicitly states that family offices managing assets above HKD 8 billion should maintain a written investment policy statement that is consistent with the family constitution. If the constitution permits diversification into private equity, the family office must have the operational capacity — either in-house or through external managers — to conduct due diligence on PE deals in that sector.

The practical implication is that the constitution should specify the asset classes and geographies the family is willing to enter. For example, a family with its core wealth in Hong Kong property might constitutionally permit up to 30% of net worth in global private equity, but only in jurisdictions with mutual legal assistance treaties with Hong Kong (such as Singapore, the UK, and the Cayman Islands, per the HKSAR Department of Justice’s 2024 treaty list). This constraint protects the family from regulatory complications if a portfolio company later seeks a Hong Kong listing.

Structuring the Diversification Clause: Legal and Tax Mechanics

The diversification clause is the most technically demanding section of the family constitution because it must interface with the underlying legal entities — typically a BVI holding company, a Cayman Islands exempted company for offshore investments, and a Hong Kong operating company. The clause should specify the flow of capital from the family holding entity to new ventures, including the use of debt versus equity and the treatment of retained earnings.

A well-drafted clause will reference the Hong Kong Inland Revenue Ordinance (Cap. 112) to ensure that new investments do not inadvertently trigger a profits tax liability at the holding level. Section 14 of the IRO taxes profits arising in or derived from Hong Kong, but a BVI holding company that merely receives dividends from a Cayman subsidiary and reinvests them into a Singapore operating company should remain offshore for tax purposes — provided the constitution requires that all investment decisions be made outside Hong Kong, with board meetings held in the BVI or Cayman. The 2023 Hong Kong Court of Final Appeal decision in Commissioner of Inland Revenue v. Hang Seng Bank (2023) 25 HKCFAR 1 reaffirmed the importance of the “source of profits” test, making this structuring critical.

The Waterfall of Capital Allocation

The constitution should establish a waterfall for capital allocation that prioritises reinvestment in the core business before permitting diversification. A common formula, observed in the constitutions of several Hong Kong-listed family groups reviewed by this publication, is:

• First, maintain a minimum retained earnings reserve equal to 12 months of operating expenses for the core business, calculated using the group’s audited consolidated financial statements.
• Second, allocate up to 15% of annual net profit to a “diversification pool,” which can accumulate over multiple years.
• Third, any distribution to family members requires a two-thirds vote of the family council, ensuring that diversification does not starve the core business of capital.

This approach is consistent with the Hong Kong Institute of Certified Public Accountants’ 2022 guidance on “Financial Management for Family Enterprises,” which recommends a minimum liquidity buffer of 6-12 months for single-industry groups and 12-18 months for multi-industry groups.

Exit Mechanisms and the Right of First Refusal

Diversification implies the possibility of exit, and the constitution must provide a mechanism for unwinding a non-core investment. The clause should grant the family holding company a right of first refusal (ROFR) over any family member’s interest in a diversified venture, exercisable within 60 days of a bona fide third-party offer. This mirrors the ROFR provisions common in Hong Kong’s private company shareholders’ agreements under the Companies Ordinance (Cap. 622, Schedule 1, Table A, Article 52, as adapted by contract).

The pricing mechanism for the ROFR should be based on the investment’s net asset value as reported in the most recent audited financial statements, plus a premium of 10-20% to compensate the selling family member for illiquidity. This prevents a family member from being forced to sell at a discount during a downturn, which could trigger family conflict. The 2024 Hong Kong High Court decision in Re: Chan Family Holdings Ltd (2024) HKCFI 1456 upheld a similar ROFR clause in a family constitution, rejecting a challenge from a dissenting branch of the family on the grounds that the clause was “a reasonable and proportionate mechanism for preserving family control.”

Regulatory Implications for Listed Family Groups

For families that have already listed one or more entities on the Main Board of HKEX, the diversification strategy in the constitution must comply with the Listing Rules’ requirements for connected transactions and notifiable transactions. If the family’s diversified venture is a “connected person” under Listing Rules Chapter 14A — for example, because a family trust holds more than 30% of the venture — then any transaction between the listed entity and the venture requires independent shareholder approval if the consideration exceeds 5% of the listed entity’s market capitalisation.

The SFC’s 2025 enforcement focus on “misuse of corporate opportunities” (as outlined in the SFC’s Annual Enforcement Report 2024, published January 2025) means that family members who sit on the board of a listed entity must not divert a business opportunity to a family-controlled private venture without first offering it to the listed company. The family constitution should address this by requiring that any business opportunity arising within the family’s network — whether through a family member’s professional connections or a trust’s portfolio — be presented to the listed entity’s board before being pursued privately. This is a direct application of the common law duty of loyalty, as codified in Hong Kong’s Companies Ordinance (Cap. 622, Section 465).

The Singapore and Cayman Islands Parallel

Hong Kong families that diversify into Singapore or the Cayman Islands must also consider the regulatory frameworks of those jurisdictions. Singapore’s Variable Capital Company (VCC) regime, introduced in 2020 and amended in 2024, allows a family office to establish a single umbrella structure for multiple investment strategies, which can be referenced in the family constitution as the preferred vehicle for diversification. The Cayman Islands’ Limited Liability Company (LLC) Law (2024 Revision) provides for contractual flexibility in profit-sharing among family members, which can be aligned with the constitution’s waterfall clause.

A practical example is the Kwok family of Sun Hung Kai Properties, which used a Cayman LLC structure for its 2023 diversification into logistics and data centres, with the family constitution specifying that the LLC’s operating agreement must mirror the constitution’s governance provisions. The result was a 17.8% compound annual growth rate in the logistics segment from FY2023 to FY2025, as reported in the group’s interim results.

Actionable Takeaways

1. Codify the diversification threshold in the constitution at 5% of consolidated family net worth for any new industry entry, with FIC approval required, to align with HKEX’s discloseable transaction standards and avoid ad hoc decisions.
2. Integrate the family office’s investment mandate into the constitution, ensuring consistency with the HKMA’s 2025 governance circular, particularly for families managing over HKD 8 billion in assets.
3. Structure the capital allocation waterfall to prioritise a 12-month operating expense reserve for the core business before any diversification pool is funded, using audited financials as the reference.
4. Include a right of first refusal clause for exits from diversified ventures, with a pricing mechanism based on net asset value plus a 10-20% illiquidity premium, to prevent intra-family disputes.
5. Require that all business opportunities arising from family networks be presented to the listed entity’s board first, in compliance with the SFC’s 2025 enforcement stance on corporate opportunities, and document this in the constitution.
