Do I need to disclose substantial shareholdings in APAC?

What is shareholding disclosure?

Substantial shareholding disclosure is a regulatory requirement for shareholders to report their equity holdings in, typically, listed issuers once their position reaches a certain percentage level of shares or voting rights. It may also be referred to as major shareholding or long position disclosures, disclosure of interest (DOI) or sometimes beneficial ownership reporting. These rules are designed to provide transparency to the market, the issuer, and the relevant regulator, and may be applicable to any firm that holds or manages shares or any instrument referenced to shares.

Substantial shareholding disclosure in APAC

There is no regional rulebook for shareholding disclosure in APAC. Restrictions vary widely by jurisdiction, with differences in thresholds, timing, instruments covered, and enforcement mechanisms.

Some interesting points of national nuance to be aware of include:

• calculation basis – tests can be very wide (e.g. “interests in shares” in Hong Kong, which is then scaled back through a series of exemptions) – or more limited (e.g. legal title in Vietnam)
• swinging threshold crossings – in Japan after the initial filing if the holding increases or decreases by 1% or more from the previously disclosed holding a change report must be submitted. This requires dynamic checks against previous disclosures, rather than using e.g. fixed thresholds (e.g. 6%, 7% etc)
• holders’ intent – this can change filing requirements, e.g. “passive” investors can rely on more relaxed timing in Japan and South Korea. What constitutes “passive” is not harmonised across the region
• issuer type – disclosures are not always limited to listed issuers, so there may be a requirement to track your holdings in unlisted shares. An issuer’s listing status can impact filing logistics (method or timing)– e.g. Taiwan and Malaysia
• language requirements – there are local language filing requirements in some countries – e.g. in China and Japan, which may necessitate assistance from a local agent or counsel

Tips for compliance

Our Shareholding Disclosure service covers more than 100 jurisdictions. While local rules vary, here are some common points to note:

• Issuers & Markets: Clarify which issuers are in scope—domestic, foreign, or dual-listed. You may need to disclose the same holding (using different calculation criteria) in more than one jurisdiction
• Thresholds: Understand initial and continuing thresholds. Thresholds can vary depending on issuer type (e.g. listing, market cap) or shareholder location (e.g. tax haven)
• Calculation: Consider voting rights, share capital, class tests, and total voting rights. Some regimes apply multiple tests. Note that black letter law may not prescribe precise calculation methods meaning local counsel input is required
• Mandate: Disclosure may be triggered by business activity, even without direct voting discretion (e.g. asset managers, custodians)
• Eligible Assets: Know which securities count—especially derivatives subject to conversion, exchange, or subscription.
• Filing Logistics: Prepare for language requirements, deadlines, formats, and portal registration
• Additional Reporting Obligations: Equity holders may face other disclosures—e.g. to industry regulators under sensitive industry or FDI rules, in takeover situations, for AML/CTF, or net short positions

Final thoughts

• Risk: Shareholding disclosure is a business-critical area of compliance, which requires daily oversight and a robust approach to tracking rule developments
• Complexity: The rules can evolve, sometimes quickly and without warning, in response to market developments or a change in regulator approach. Rule changes or interpretive developments can be difficult to detect – often the changes are not readily apparent nor the subject of major public announcements
• Sanctions: National regulators can apply significant scrutiny to this area of compliance and can expect firms to have a robust control framework in place. The margins of error can be very small, and notifications deadlines can be tight. A single missed disclosure can have significant regulatory consequences. In some countries non-disclosure is a criminal offence. Reputational risk relating to a public sanction is also a consideration
