Disclosure of interests under the SFO

Part XV of the Securities and Futures Ordinance (SFO) makes certain ownership and control interests visible to the market. Its purpose is to give investors timely information about who may control voting shares or benefit from transactions involving a listed corporation. It is a disclosure regime for listed corporations; it is not the SFC licensing test for substantial shareholders of a licensed corporation.

Who has a Part XV disclosure duty?

The SFC highlights two main groups. Substantial shareholders must disclose interests and short positions in voting shares of a listed corporation. A substantial shareholder for this purpose is an individual or corporation interested in 5% or more of a class of voting shares. Directors and chief executives of a listed corporation have a distinct duty: they disclose interests and short positions in shares of that corporation or its associated corporations, and interests in debentures of those corporations.

The categories are not interchangeable. A person may be required to disclose as a substantial shareholder because of a 5% threshold, while a director or chief executive has a duty attached to office that can apply even below that percentage. When reading a fact pattern, identify the person's capacity before applying a threshold.

The 5% threshold

For the substantial-shareholder regime, the starting point is whether a person is interested in 5% or more of the relevant voting shares. The SFO then sets out when the duty arises and which events trigger a notice. Reaching the threshold, falling below it, or crossing a notifiable percentage level can matter. The question may also involve a change in the nature of an interest or a short position.

Do not confuse this 5% SFO test with the Listing Rules concept of a substantial shareholder, which can arise in a different context and uses its own definitions. Nor should it be confused with section 132 SFO, which concerns the SFC's approval of a substantial shareholder of a licensed corporation. Part XV concerns disclosure of interests in listed corporations; section 132 is part of the intermediary licensing regime.

Interests and short positions

The regime covers more than a person's name appearing as registered owner. The SFO contains rules for attributing interests, including certain family, corporate, trust, and agreement arrangements. Questions may therefore describe control or an arrangement that gives a person an interest even when another person holds the shares directly. Work from the statutory attribution rules stated or implied in the question rather than assuming registration is the whole test.

A short position is separately relevant. Do not net a short position against a long interest and report only the balance unless the applicable statutory rules say to do so. Part XV distinguishes interests from short positions and imposes reporting obligations for both in the circumstances it specifies.

What the notice system does

Notifications use prescribed forms and are filed electronically through the Hong Kong Exchanges and Clearing Disclosure of Interests Online System. The SFC publishes the forms and completion directions. Listed corporations keep registers of disclosed interests, while the exchange makes filing information available to the market.

A practical way to analyze an exam scenario is to ask: Is the issuer a listed corporation? Is the person a substantial shareholder, director, or chief executive? What securities and type of position are involved? Has a statutory trigger occurred? Which prescribed notice and filing process apply? A real filing requires checking the current SFO, current forms, and the precise facts.

Common exam traps

• Applying the 5% substantial-shareholder threshold to a director's separate disclosure duty.
• Confusing listed-corporation disclosure under Part XV with licensing approval for a substantial shareholder of an SFC-licensed corporation under section 132.
• Assuming only registered legal ownership can count, without considering the SFO's attribution rules.
• Treating short positions as though they disappear when compared with a long position.
• Using a Listing Rules threshold or definition as though it replaced the SFO test.

The exam distinction

Part XV is the market transparency regime for interests in listed corporations. For substantial shareholders, remember the 5% entry threshold; for directors and chief executives, identify the separate office-based scope. Then apply the relevant event and attribution rules. Keep this separate from SFC licensing approval, which deals with ownership of a licensed corporation.

Part XV has separate rules for substantial shareholders and for directors or chief executives of listed corporations. For substantial shareholders, identify the listed corporation and class of voting shares, calculate interests and short positions under the statutory attribution rules, and compare with the current notifiable threshold. Directors and chief executives have a broader set of interests to disclose, including relevant shares and debentures in their listed corporation and associated corporations. Do not apply the substantial-shareholder percentage test as if it were the only Part XV duty.

Track events and filing deadlines

A notifiable event may include acquiring or ceasing an interest, a change in the nature of an interest, or a change in the percentage level. The person with the duty must identify the event date and file the appropriate notice through the SFC’s prescribed system within the statutory period. Listed corporations also have duties connected to receiving and publishing notices. Maintain a ledger of holdings, derivatives, voting rights, corporate actions, and event dates rather than waiting for a quarterly reconciliation.

Attribution and exceptions need careful review

Interests can be attributed through controlled corporations, agreements, or other statutory rules. A nominee arrangement, stock loan, option, or derivative can change the analysis even if registered ownership appears unchanged. Part XV also contains exemptions and special treatment; do not assume every economic exposure is treated identically. Use the current SFO and SFC forms and notes, and seek compliance review when a transaction has multiple entities or instruments.

Example and exam takeaway

An investor crosses a notifiable percentage level in a listed class after a share acquisition. The investor must identify the event, aggregate interests under the SFO rules, and submit the correct notice by the deadline. A director’s reportable interest is assessed under a distinct duty. For exam questions, specify the person, role, listed issuer, class, interest type, event, threshold, and filing route.
