Part of the Hong Kong Stock Loan Regulatory & Eligibility Guide — view the full guide
Most of the disclosure around a Hong Kong share-backed loan falls on the shareholder. Two Main Board Listing Rules put a duty on the listed company instead, and they are narrower than they are often thought to be.
This note explains what Rules 13.17 and 13.18 of the Main Board Listing Rules require, when a controlling shareholder's own stock loan is and is not caught, and how the rules sit beside the shareholder’s filings under SFO Part XV. It is orientation, not legal advice.
What does Rule 13.17 require?
Rule 13.17 requires the issuer to make an announcement, as soon as reasonably practicable, when its controlling shareholder has pledged shares to secure the issuer’s debts, or guarantees or other support of the issuer’s obligations.
The rule’s words are that the controlling shareholder "has pledged all or part of its interest in the issuer’s shares to secure the issuer’s debts or to secure guarantees or other support of its obligations". The announcement must give the number and class of shares pledged, the amounts of the debts, guarantees or other support, and any other details needed to understand the arrangement (Main Board Rule 13.17).
HKEX reads "pledge" broadly. Its FAQ says the rule applies to "any arrangement, in any form and however the arrangement is named", where the controlling shareholder directly or indirectly uses its shares to secure the issuer’s debts or obligations. Unlike Rules 13.18 and 13.19, Rule 13.17 contains no test of significance.
A controlling shareholder is, broadly, a person or group able to exercise or control 30% or more of the voting power at general meetings, or to control the composition of a majority of the board (Rule 1.01). Rule 13.12 says these issues are viewed on a group basis; whether that brings in a pledge securing a subsidiary’s debts is a question for Hong Kong counsel.
What does Rule 13.18 require?
Rule 13.18 is not a pledge rule. It applies when the issuer or a subsidiary enters into a loan agreement that imposes specific performance obligations on a controlling shareholder, and a breach would cause a default on loans significant to the issuer’s operations.
The rule’s own example of such an obligation is "a requirement to maintain a specified minimum holding in the share capital of the issuer". The issuer must announce, as soon as reasonably practicable, the aggregate level of the facilities that a breach may affect, the life of the facility, and the obligation imposed on the controlling shareholder (Main Board Rule 13.18).
Its neighbour, Rule 13.19, applies once a breach happens: where the issuer breaches the terms of loan agreements for loans significant to its operations, the lenders may demand immediate repayment and have not waived the breach, the issuer must announce it as soon as reasonably practicable.
Does a controlling shareholder’s personal stock loan trigger either rule?
Usually not. A pledge that secures only the shareholder’s own borrowing falls outside the words of Rule 13.17, and Rule 13.18 covers only loan agreements that the issuer or a subsidiary enters into.
Three other routes can still bring a personal pledge into an announcement or a filing. In the first 12 months after listing, Rule 10.07(2) Note (3) requires a controlling shareholder to tell the issuer immediately of shares pledged to an authorised institution for a bona fide commercial loan, and of any indication that the pledgee will dispose of them; the issuer must then announce as soon as possible.
Second, the SFC’s Guidelines on Disclosure of Inside Information list "pledge of the corporation’s shares by controlling shareholders" among events where an issuer should consider whether a disclosure obligation arises; if it does, Rule 13.09(2)(a) requires a simultaneous announcement. Third, the shareholder’s own SFO Part XV duties apply regardless, as the next section explains.
There is also an indirect link. If the issuer’s own facilities require the controlling shareholder to keep a minimum holding, enforcement of a personal pledge could breach that covenant and engage Rules 13.18 and 13.19. Whether a given structure is caught, including a personal facility that in substance supports the issuer, is a fact question for the borrower’s Hong Kong counsel.
How do these rules relate to SFO Part XV and Practice Note 19?
They work at different levels: Rules 13.17 and 13.18 oblige the issuer to announce, while SFO Part XV obliges the shareholder, and sometimes the pledgee, to file. Practice Note 19 no longer applies; it was repealed on 31 March 2004.
Under Part XV, a substantial shareholder who creates a security interest changes the nature of its interest, which is reportable within three business days unless an exemption applies, for example where the lender is a qualified lender such as a bank or licensed broker (SFC: Part XV disclosure of interests). Directors have no 5% floor. Our note on SFO Part XV disclosure for stock loans covers the shareholder’s side in detail.
Practice Note 19 is a different story. HKEX’s rulebook lists it as repealed, and an HKEX release of 2005 described its paragraph 3.7.1 as equivalent to today’s Rule 13.18. Our note on Practice Note 19 and financial assistance explains the issuer-level rules that apply now.
What must appear in interim and annual reports?
Rule 13.21 requires the disclosures made under Rules 13.17, 13.18 and 13.19 to be repeated in later interim and annual reports for as long as the circumstances giving rise to them continue (Main Board Rule 13.21).
Appendix D2 to the Main Board Listing Rules, on financial disclosure, lists the same three items for annual and interim reports. On GEM, Rule 17.23 does the same for Rules 17.19 to 17.21, and also covers pledges notified after listing under Rule 17.43. The wider map of rules around a stock loan is in our Hong Kong regulatory guide.
This article is educational and is not legal or regulatory advice. Whether Rules 13.17 to 13.21, Rule 10.07, the inside-information provisions or SFO Part XV apply to a particular pledge is a question for your own Hong Kong legal counsel and the issuer’s advisers. Hong Kong Stock Loans acts as an arranger and introducer in collaboration with SFC-licensed counterparties.
