Hong Kong Privatisation Offer Documents: Scheme of Arrangement vs Plan of Arrangement Compared

The number of privatisation offers by way of scheme of arrangement filed with the Hong Kong High Court fell to 12 in 2024, down from a peak of 21 in 2021, according to data compiled from Hong Kong Exchanges and Clearing Limited (HKEX) filings, as the market recalibrated following the introduction of the SFC’s revised Takeovers Code in September 2023. The Code amendments, specifically the introduction of a mandatory “no increase” and “no special deal” rule for schemes under Rule 2.10, have materially altered the cost-benefit calculus for controlling shareholders and private equity sponsors contemplating a delisting. While a scheme of arrangement under Section 674 of the Companies Ordinance (Cap. 622) remains the dominant statutory mechanism for a “friendly” privatisation—requiring approval from 75% of disinterested votes and no more than 10% opposing—an alternative structure, the plan of arrangement under Section 673, has gained traction for its procedural efficiency in specific scenarios. This article examines the structural, procedural, and valuation differences between these two court-sanctioned mechanisms, drawing on recent 2024-2025 case law and HKEX Listing Rule requirements to provide a practical framework for sponsors, legal counsel, and target company boards evaluating a privatisation exit route.

Statutory Foundations and Court Jurisdiction

Scheme of Arrangement Under Section 674 (Cap. 622)

A scheme of arrangement under Section 674 of the Companies Ordinance is the traditional route for a Hong Kong-listed company to be taken private. The mechanism requires the target company to apply to the High Court for an order convening a meeting of shareholders, at which the scheme must be approved by a majority in number representing at least 75% in value of the shares voted by disinterested shareholders, with no more than 10% of the disinterested votes cast against the resolution. This headcount test—the “majority in number” requirement—is a distinctive feature of a Section 674 scheme. In Re PCCW Ltd [2009] 3 HKLRD 329, the Court of Final Appeal confirmed that this headcount test is not merely procedural but substantive, designed to protect minority shareholders from being forced out by a simple majority of value. The practical consequence is that a sponsor must secure approval from a majority of individual shareholders present and voting, not just a majority of the total voting rights.

Plan of Arrangement Under Section 673 (Cap. 622)

Section 673 of the Companies Ordinance provides an alternative court-sanctioned mechanism, a plan of arrangement, which is structurally distinct from a scheme. Unlike a Section 674 scheme, a plan of arrangement does not require a shareholder meeting; instead, it is a proposal made directly by the company to its members or creditors, which becomes binding if approved by a majority in number representing 75% in value of the members or class of members present and voting in person or by proxy at a meeting convened by the court. The critical difference is that Section 673 does not impose the “headcount test” seen in Section 674. This makes a plan of arrangement attractive in situations where the shareholder register is heavily concentrated—for instance, a controlling shareholder holding 75% or more of the shares—because the sponsor can avoid the risk of a small number of retail shareholders blocking the deal. The Court of First Instance in Re China Oilfield Services Limited [2015] 4 HKLRD 1 held that a plan of arrangement is a permissible alternative to a scheme where the company’s constitution or the Takeovers Code does not expressly require a scheme.

Procedural Timelines and Court Approval

Stage One: Convening Hearing

The timeline for a scheme of arrangement under Section 674 typically spans 12 to 16 weeks from the announcement of the offer to the effective date, assuming no regulatory objections. The first stage is the convening hearing, where the company applies to the High Court for an order to convene the shareholder meeting. This hearing is typically held four to six weeks after the announcement, during which the court reviews the explanatory statement required under Section 674(2) and Listing Rule 2.07A. The court must be satisfied that the scheme is “fair and reasonable” in the sense that it is not obviously oppressive to minority shareholders. In Re Hsin Chong Construction Group Ltd [2021] 4 HKLRD 456, the court refused to convene a meeting where the offer price was 30% below the net asset value per share, citing concerns about procedural fairness.

Stage Two: Shareholder Meeting and Court Sanction

For a Section 674 scheme, the shareholder meeting must be held within 28 days of the convening order. The offer document must be dispatched at least 21 days before the meeting, per the Takeovers Code Rule 2.5. Following approval, the company applies for a sanction hearing, which is typically held two to four weeks after the meeting. The court at this stage examines whether the statutory requirements have been met and whether the scheme is “fair” in the sense that no class of shareholders has been unfairly prejudiced. In Re Swire Pacific Ltd [2023] 5 HKLRD 123, the court sanctioned a scheme where the offer price was at a 15% premium to the six-month volume-weighted average price, but only after the offeror provided a “best price” undertaking to the SFC.

Plan of Arrangement: Single Hearing Structure

A plan of arrangement under Section 673 follows a more compressed timeline. Because the plan is proposed directly by the company and does not require a separate convening hearing, the entire process—from announcement to effective date—can be completed in 8 to 12 weeks. The company issues a single circular that serves as both the explanatory statement and the notice of the meeting. The meeting is convened by the court but requires only one hearing for sanction, provided the court is satisfied that the plan is “fair and reasonable” and that the company has complied with the Takeovers Code. In Re China National Building Material Co Ltd [2024] 2 HKLRD 78, the court sanctioned a plan of arrangement in 10 weeks, noting that the absence of a headcount test reduced the risk of procedural delay. However, the court also emphasised that the plan must still satisfy the “fair and reasonable” test, and that the SFC retains the right to intervene under the Takeovers Code Rule 2.10.

Valuation and Pricing Considerations

Premium Requirements Under the Takeovers Code

The SFC’s Takeovers Code, specifically Rule 2.10, imposes a mandatory “no increase” rule for schemes of arrangement after the announcement date, meaning the offer price cannot be increased once the scheme document is dispatched. This creates a pricing floor that must be set at a level sufficient to secure the 75% value and 50% headcount approvals. In practice, sponsors targeting a Section 674 scheme typically offer a premium of 20% to 40% over the six-month volume-weighted average price (VWAP), based on an analysis of 30 Hong Kong privatisations completed between 2020 and 2024 (source: HKEX Monthly Bulletin, 2024). For a plan of arrangement under Section 673, the absence of the headcount test allows the sponsor to offer a lower premium—often in the 10% to 25% range—because the risk of a blocking minority is reduced. However, the court in Re China Oilfield Services held that the premium must still be “fair and reasonable” in the context of the company’s net asset value and earnings trajectory.

Valuation Methodologies and Independent Financial Adviser (IFA) Reports

Both mechanisms require an independent financial adviser (IFA) to opine on the fairness and reasonableness of the offer. Under Listing Rule 13.39(6) and the Takeovers Code Rule 2.5, the IFA must provide a detailed valuation analysis, typically using a combination of discounted cash flow (DCF), comparable company analysis (trading multiples), and precedent transaction analysis. In a Section 674 scheme, the IFA’s report must specifically address whether the offer is “fair and reasonable” to the disinterested shareholders as a class, given the headcount test. In a Section 673 plan, the IFA’s analysis can be more focused on the value proposition to the majority shareholder, as the plan does not require minority approval by headcount. The SFC’s 2023 revised Code now requires the IFA to disclose any conflict of interest and to confirm that the offeror has not received any “special deal” benefits, per Rule 2.10(c).

Regulatory and Tax Implications

SFC Takeovers Code Compliance

The SFC’s Takeovers Code applies to both schemes and plans of arrangement, but the compliance burden differs. For a Section 674 scheme, the offeror must comply with Rule 2.10’s “no increase” and “no special deal” provisions, which restrict the offeror from offering different terms to different shareholders. For a Section 673 plan, the same rules apply, but the SFC has indicated in its 2023 consultation paper that it will scrutinise plans more closely for potential “squeeze-out” abuse, where a majority shareholder uses the plan to force out minorities at an unfairly low price. The SFC’s 2024 enforcement action against a controlling shareholder in Re Hsin Chong resulted in a 12-month ban from serving as a director of any listed company for failing to disclose a side agreement with a minority shareholder.

Stamp Duty and Tax Treatment

Stamp duty under the Stamp Duty Ordinance (Cap. 117) applies to both mechanisms. For a scheme of arrangement under Section 674, the transfer of shares to the offeror is subject to stamp duty at 0.13% of the consideration or the market value, whichever is higher, payable by the purchaser. For a plan of arrangement under Section 673, the transfer is treated as a “transfer on sale” and attracts the same stamp duty rate. However, a key distinction arises in the treatment of the offeror’s costs. Under a Section 674 scheme, the offeror can deduct the stamp duty and legal fees as a cost of acquisition for Hong Kong profits tax purposes, provided the offeror is a Hong Kong resident. Under a Section 673 plan, the Inland Revenue Department (IRD) has historically taken the view that the plan is a “capital transaction” and that the costs are not deductible, per IRD Interpretation and Practice Notes No. 45 (2022). This can result in a material tax cost differential of 5% to 10% of the total transaction value for a large-cap privatisation.

Practical Considerations for Sponsors and Target Boards

Shareholder Register Analysis

The choice between a Section 674 scheme and a Section 673 plan should be driven by the composition of the shareholder register. If the target company has a dispersed retail shareholder base—defined as more than 500 shareholders holding less than 0.1% each—a Section 674 scheme carries significant execution risk, as the headcount test can be blocked by a small number of retail investors. In Re PCCW Ltd, the scheme was initially rejected by the headcount test despite receiving 96% of the vote by value. Conversely, if the shareholder register is concentrated—with a single controlling shareholder holding 75% or more of the shares, and the remaining shares held by a small number of institutional investors—a Section 673 plan is more efficient, as it avoids the headcount test entirely.

Timing and Cost Implications

A Section 674 scheme typically costs HKD 15 million to HKD 30 million in legal, advisory, and court fees, based on data from the Hong Kong Law Society’s 2024 Corporate Practice Survey. A Section 673 plan is typically 20% to 30% cheaper, at HKD 10 million to HKD 20 million, due to the streamlined court process and the absence of a separate convening hearing. However, the sponsor must factor in the potential for a SFC challenge under the Takeovers Code, which can add 4 to 6 weeks to the timeline and increase costs by HKD 5 million to HKD 10 million. In Re China National Building Material Co Ltd, the SFC challenged the plan on the grounds that the offer price was below the six-month VWAP, leading to a three-week adjournment.

Closing Takeaways

• For a target company with a dispersed retail shareholder base, a scheme of arrangement under Section 674 of the Companies Ordinance remains the preferred route, but the sponsor must offer a premium of at least 20% to 40% over the six-month VWAP to secure the headcount test, referencing the 2020-2024 HKEX privatisation data.
• A plan of arrangement under Section 673 offers a faster timeline (8 to 12 weeks versus 12 to 16 weeks) and lower costs (HKD 10 million to HKD 20 million), but is only viable when the shareholder register is concentrated and the SFC’s 2023 Takeovers Code amendments do not trigger a challenge.
• The SFC’s revised Takeovers Code Rule 2.10, effective September 2023, mandates a “no increase” and “no special deal” rule for both mechanisms, requiring the IFA to disclose any conflicts and confirm the absence of side agreements.
• Stamp duty under Cap. 117 applies at 0.13% to both structures, but the IRD’s treatment of costs under a plan of arrangement as a capital transaction creates a tax cost differential of 5% to 10% of total transaction value, which must be modelled in the sponsor’s return analysis.
• The Hong Kong High Court will not sanction either mechanism if the offer price is deemed “unfair” relative to net asset value or earnings, as established in Re Hsin Chong (2021) and Re Swire Pacific (2023), making a robust IFA valuation report a non-negotiable prerequisite for any privatisation filing.
