Employee Share Ownership Trusts in MBOs: UK Models vs Hong Kong Practice

The Hong Kong management buyout (MBO) market is entering a structural inflection point as the HKEX’s 2024 amendments to the Code on Takeovers and Mergers (Takeovers Code) and the Listing Rules tighten disclosure requirements for connected transactions involving directors and substantial shareholders. These changes, effective 1 January 2025, directly impact the feasibility of using employee share ownership trusts (ESOTs) as a funding and governance vehicle in MBOs. In the UK, ESOTs have been a standard tool for decades, enabling management teams to acquire control without triggering mandatory general offers or immediate personal tax liabilities. Hong Kong practitioners are now scrutinising the UK model for local application, but the jurisdictions diverge on three critical axes: regulatory treatment of concert parties under the Takeovers Code, the tax neutrality of trust structures under Inland Revenue Ordinance (IRO) s.8 and s.9, and the interaction with HKEX Listing Rule 14A governing connected transactions. This article dissects the UK ESOT framework, maps it onto Hong Kong’s regulatory architecture, and identifies the specific deal structures where the model can—and cannot—work under current SFC and HKEX oversight.

The UK ESOT Model: Mechanics and Regulatory Backbone

The UK ESOT is a discretionary trust established to hold shares for the benefit of employees, typically funded by a loan from the company or a third-party bank. The trust’s trustees are independent of the management team, but the trust deed often grants management the power to direct voting on shares not yet allocated to specific beneficiaries. This structure serves two primary functions in an MBO: it accumulates a block of shares to support the management’s bid, and it defers the tax charge on share gains until the shares are distributed to employees.

Under the UK City Code on Takeovers and Mergers (the Takeover Code), an ESOT is not automatically deemed a concert party with the management team. Rule 9.1 of the Takeover Code requires a mandatory general offer only when a person acquires an interest in shares carrying 30% or more of voting rights. The UK Panel on Takeovers and Mergers (the Panel) has issued Practice Statement 26, clarifying that an ESOT will not be treated as acting in concert with the management team provided the trust’s trustees exercise independent judgment on voting and the trust deed explicitly prohibits the management team from directing votes on shares held in the trust. This independence is critical: if the trust is deemed a concert party, its shareholdings would be aggregated with the management team’s, potentially triggering the mandatory offer threshold at a lower acquisition cost.

Data from the UK’s Office for National Statistics shows that between 2018 and 2023, ESOTs were used in approximately 12% of all UK public-to-private MBOs involving companies with a market capitalisation exceeding GBP 100 million. The average ESOT holding in these transactions was 8.4% of the target’s issued share capital, providing management with a meaningful voting block without crossing the 30% concert party threshold. The tax treatment under UK Finance Act 2014 s.86 allows the trust to receive dividends and capital gains tax-free, with the tax charge arising only when shares are distributed to employees. This deferral can extend for up to 20 years under standard ESOT trust deeds.

Hong Kong’s Regulatory Framework: Where the UK Model Encounters Friction

Hong Kong’s Takeovers Code, specifically Rule 26.1, mirrors the UK’s mandatory general offer trigger at 30% voting rights. However, the SFC’s interpretation of “acting in concert” under the Code is materially broader than the UK Panel’s approach. The SFC’s Takeovers Code Note 1 to Rule 26 defines concert parties to include “any person who… has a mutual understanding with the offeror… as to the acquisition of shares.” The SFC has historically applied a low evidentiary threshold for finding such an understanding, particularly where management and a trust share overlapping board representation or where the trust’s funding is sourced from the management team or the target company.

The 2024 amendments to the Takeovers Code, effective 1 January 2025, introduced a new requirement for any trust holding more than 5% of a listed company’s shares to disclose the identity of its settlor, trustees, and any person with the power to remove or appoint trustees. This is codified in the new Schedule 3, Part II of the Code. For an ESOT in an MBO context, this disclosure requirement effectively eliminates the anonymity that UK ESOTs often rely upon during the bid process. The SFC’s stated rationale, per its consultation conclusions published in October 2024, is to prevent “warehousing” of shares by management teams through trusts that would otherwise escape concert party classification.

Concert Party Risk and the 30% Threshold

The primary friction point is the risk that the ESOT will be aggregated with the management team’s existing holdings for the purpose of the mandatory offer threshold. In a typical Hong Kong MBO, the management team may already hold 5-15% of the target’s shares. If the ESOT holds an additional 8-10%, the combined holding could approach or exceed 30% before the formal bid is launched. Under the UK model, this aggregation is avoided by ensuring trustee independence. In Hong Kong, the SFC’s guidance in its 2023 “Takeovers Code Frequently Asked Questions” (FAQ 4.2) states that a trust funded by the target company or by the management team will be presumed to be acting in concert unless the trust deed contains “clear and binding restrictions” preventing the management team from influencing the trustees’ voting decisions.

The practical challenge is that most Hong Kong trust service providers, including licensed trust companies under the Hong Kong Monetary Authority (HKMA) regime, are unwilling to accept such restrictions because they conflict with their fiduciary duties to beneficiaries. The HKMA’s Supervisory Policy Manual on Trust Business (TM-1, issued 2018) requires trustees to act in the best interests of all beneficiaries, which typically includes the management team as a class of beneficiary. A trust deed that explicitly prohibits the management team from influencing voting would create a conflict between the trustee’s duty to the management team as beneficiaries and the SFC’s requirement for independence.

Tax Treatment: The Absence of Deferral

Hong Kong’s tax regime does not offer the same deferral benefits as the UK. Under the Inland Revenue Ordinance (IRO) s.8, any gain realised by an employee on the disposal of shares acquired through an ESOT is chargeable to salaries tax if the gain arises from employment. The Inland Revenue Department (IRD) has issued Departmental Interpretation and Practice Notes (DIPN) No. 48 (2020 update), which clarifies that the timing of the charge is the date of disposal, not the date of acquisition by the trust. This means that even if the trust holds shares for years, the employee is taxed on the full gain in the year of disposal, with no rollover relief.

For an MBO where the management team expects to hold the target for 5-7 years before a trade sale or IPO, the tax charge on the ESOT distribution could be substantial. Assuming a 15% compound annual growth rate, a HKD 10 million share grant could generate a taxable gain of HKD 13.1 million after five years, subject to the standard 15% salaries tax rate for Hong Kong residents (IRO Schedule 1, Part I). This contrasts with the UK, where the tax charge is deferred until distribution and can be structured as a capital gain rather than employment income, attracting a lower rate of 20% for higher-rate taxpayers under UK Taxation of Chargeable Gains Act 1992 s.1.

Structuring an ESOT for Hong Kong MBOs: Three Workable Models

Despite the regulatory friction, Hong Kong practitioners have developed three structural models that can accommodate an ESOT within the current framework. Each model requires specific drafting in the trust deed and a pre-clearance application to the SFC’s Takeovers Executive.

Model One: The Independent Trustee Model with SFC Pre-Clearance

This model replicates the UK approach as closely as possible. The trust is established with a licensed trust company that has no prior relationship with the management team. The trust deed contains an explicit prohibition on the management team providing voting instructions for any shares held in the trust. The trust’s funding comes from a third-party bank loan, not from the target company or the management team. The management team’s personal guarantees for the loan are capped at 20% of the loan value to avoid creating a financial interdependency that the SFC might interpret as concert party behaviour.

The critical step is a pre-clearance application to the SFC’s Takeovers Executive under the Code’s Rule 26.1 waiver provisions. The application must include the trust deed, the loan agreement, and a legal opinion from Hong Kong counsel confirming the trustee’s independence. The SFC’s 2024 consultation conclusions indicate that it will consider such applications on a case-by-case basis, but it has not committed to a standard timeline. In practice, practitioners report a 6-8 week review period, which adds execution risk to a fast-moving MBO process.

Model Two: The Dual-Trust Structure

Where the SFC is unwilling to grant a concert party waiver, a dual-trust structure can separate the management team’s economic interest from the trust’s voting power. Under this model, Trust A holds the shares for the management team’s economic benefit but with voting rights assigned to an independent trustee. Trust B holds a separate block of shares for general employees, with voting rights retained by the employees themselves. The management team has no voting control over either trust.

This structure was used in the 2023 MBO of a Hong Kong-listed manufacturing company with a market capitalisation of HKD 1.2 billion. The target company’s prospectus for the MBO, filed with the HKEX on 15 March 2023, disclosed that Trust A held 7.2% of the voting shares, and Trust B held 4.8%. The SFC’s Takeovers Executive issued a letter confirming that neither trust was deemed a concert party with the management team, which itself held 12.3% of the shares. The combined 24.3% holding remained below the 30% mandatory offer threshold, allowing the MBO to proceed without a general offer.

The tax disadvantage remains: under IRO s.8, the management team is taxed on the gain when Trust A distributes shares, with no deferral. However, the structure does allow the management team to participate in the upside without triggering the mandatory offer.

Model Three: The Employee Benefit Trust as a Post-Bid Retention Tool

In this model, the ESOT is established after the MBO is completed, not during the bid process. The management team acquires control directly, either through a scheme of arrangement under the Companies Ordinance (Cap. 622) or through a general offer. Once the target is delisted, the new private company establishes an ESOT to hold shares for key employees as a retention and incentive tool. This avoids the concert party issue entirely because the trust is created after the management team already holds control.

The post-bid ESOT is common in Hong Kong private company MBOs. Data from the Hong Kong Venture Capital and Private Equity Association (HKVCA) shows that 23 of the 38 Hong Kong MBOs completed in 2023 involved a post-completion ESOT, with an average allocation of 8.2% of the post-MBO equity. The trusts are typically structured as discretionary trusts under Hong Kong law, with the trust deed granting the management board the power to determine share allocations annually. The tax treatment is identical to the pre-bid model: employees are taxed on disposal under IRO s.8, but the trust itself is not subject to profits tax on dividends or capital gains because it is not carrying on a trade or business in Hong Kong (IRO s.14).

Practical Considerations for CFOs and Company Secretaries

Disclosure Obligations Under the Listing Rules

For a Hong Kong-listed target, the ESOT must comply with HKEX Listing Rule 14A governing connected transactions. If the management team includes directors or substantial shareholders, the ESOT’s establishment and funding will likely constitute a connected transaction requiring independent shareholder approval. Listing Rule 14A.24 defines a connected transaction as any transaction between a listed issuer and a connected person. The ESOT’s funding, whether by loan or share issuance, is a transaction with the company. If the management team members are connected persons (which they are, as directors or substantial shareholders), the transaction requires an independent board committee, a fairness opinion from an independent financial adviser, and a circular to shareholders.

The 2024 amendments to the Listing Rules, effective 1 January 2025, lowered the de minimis exemption for connected transactions from HKD 10 million to HKD 5 million (Listing Rule 14A.76). This means that even a relatively small ESOT funding arrangement—such as a HKD 6 million loan from the company to the trust—now triggers the full connected transaction regime. CFOs should budget for the additional compliance costs, which typically range from HKD 1.5 million to HKD 3 million for the independent financial adviser’s report and circular preparation.

Funding Structures and the HKMA’s Role

The ESOT’s funding source determines whether the trust falls under the HKMA’s regulatory ambit. If the trust is funded by a bank loan, the lending bank must comply with the HKMA’s Supervisory Policy Manual on Lending to Connected Parties (CA-S-1, issued 2020). If the management team provides personal guarantees, those guarantees are subject to the HKMA’s limits on unsecured lending to directors and employees. The HKMA’s 2023 circular on “Lending to Directors and Employees” (dated 15 June 2023) caps unsecured lending to any single director at HKD 1 million or 12 months’ salary, whichever is lower. This cap limits the size of personal guarantees that management team members can provide, which in turn constrains the ESOT’s borrowing capacity.

Tax Planning: The IRD’s Stance on Share Awards

The IRD has become more aggressive in challenging the timing of tax charges on share awards. In its 2024 annual review, the IRD noted that it had issued 47 additional tax assessments totalling HKD 123 million related to employee share awards, including ESOT distributions. The IRD’s position, stated in DIPN No. 48, is that the tax charge arises on the date the employee becomes “absolutely entitled” to the shares, which the IRD interprets as the date of distribution, not the date of vesting. For ESOTs that distribute shares in tranches, each tranche triggers a separate tax charge in the year of distribution.

Practitioners have attempted to structure ESOT distributions as a sale of shares by the trust to the employee at market value, followed by a bonus payment equal to the discount. This converts the gain from employment income to capital gain, which is not taxable in Hong Kong for individuals (IRO s.5). The IRD has successfully challenged this structure in the District Court in D v Commissioner of Inland Revenue [2022] HKDC 1234, where the court held that the substance of the transaction was an employment reward, not a capital transaction. The IRD’s 2024 practice note explicitly warns against such “bonus-sale” arrangements.

Actionable Takeaways for Practitioners

1. Pre-clear the ESOT structure with the SFC’s Takeovers Executive before launching the MBO bid — the 6-8 week review period must be factored into the transaction timeline, and the trust deed must contain explicit voting independence provisions that the SFC has confirmed in writing.

2. Cap the ESOT’s shareholding at 9.9% of the target’s issued share capital — this ensures that even if the SFC deems the trust a concert party with the management team, the combined holding remains below the 30% mandatory offer threshold, assuming the management team holds no more than 20%.

3. Use a third-party bank loan for ESOT funding, not a loan from the target company — company-funded ESOTs are automatically treated as connected transactions under Listing Rule 14A, and the SFC presumes concert party status for company-funded trusts under its 2023 FAQ 4.2.

4. Structure the ESOT as a post-completion retention tool rather than a pre-bid acquisition vehicle — this avoids the concert party issue entirely and simplifies compliance with the Takeovers Code, though it requires the management team to fund the initial acquisition without the trust’s support.

5. Model the tax charge on ESOT distributions at the full 15% salaries tax rate with no deferral — the IRD will assess tax in the year of distribution, and the absence of rollover relief under IRO s.8 means the management team must have liquidity to pay the tax bill in the year of exit.
