Disclosure requirements

In addition, clients advised that local laws and regulations in Hong Kong (including the Ordinance, Section 329) may require CBL to disclose securities trading and holding information and the identity of the final beneficial owners of certain securities.

In order to comply with such legislation, clients safekeeping corporate securities and related derivative instruments that are listed in Hong Kong are required to disclose beneficial owner details upon request. Listed companies may request such information directly from local custodians and account holders or may appoint an agent to manage such requests.

Background and legal basis

Sections 310 and 324 of the Ordinance set out the legal framework for holders of securities listed in Hong Kong to disclose significant shareholding interests. Section 329 of the Ordinance outlines the power of a listed corporation to investigate ownership of interests in its shares.

Article 13 of the Certain Provisions on Shanghai-Hong Kong Stock Connect Pilot Program (the "CSRC Stock Connect Rules") and the SSE China Connect Rules (Articles 34 and 36) establish the rules for holders of Mainland incorporated company's shares listed in both China and Hong Kong on the disclosure of interests obligation. The same disclosure rules apply to Shenzhen-Hong Kong Stock Connect.

Bond Connect disclosure requirements follow the Rules for Bond Transactions and Circulation of National Interbank Funding Centre.


Hong Kong

It is a criminal offence, under penalty of a fine of up to HKD 100,000 or up to two years imprisonment, for a person to fail, without reasonable grounds, to fulfil the obligation to make a disclosure.

  • Order for corrective action;
  • Regulatory dialogue;
  • Issue of warning letters;
  • Record in the creditworthiness database the details of the offense or the failure to perform the public undertaking and make a public announcement;

Obligation to report threshold crossings

The acquisition of 5% and/or more of any company listed in Hong Kong requires that the shareholding be disclosed, with the obligation to report falling upon the beneficial owner; that is, the party eligible to vote.

For disclosure of interest notifications, filing of Part XV notifications must be submitted electronically through a new Disclosure of Interests Online system (DION system) introduced by HKEx.

Electronic filing:




Under Section 329 of the Ordinance, bare trustees and exempt custodians are not required to report interests in securities unless requested by the listed company. It remains the duty of beneficial owners of shares to disclose their notifiable interests.
