Key Takeaways
- ASIC has updated RG 222 – Substantial Holding Disclosure and Tracing Requirements as part of Australia’s enhanced beneficial ownership disclosure reforms commencing on 4 December 2026.
- RG 222 provides guidance on substantial holding disclosure obligations and ownership tracing requirements, emphasising on identifying the complete economic and control exposure to an Australian listed entity.
- 5% substantial holding threshold remains the core trigger; however, the assessment has become broader than ordinary share ownership; derivatives, offsetting short positions, relevant interests (particularly deemed economic interest), and applicable associates must be taken into consideration. Substantial holders must now provide full technical disclosure rather than minimal disclosure.
Introduction
The Australian Securities and Investments Commission (ASIC) has updated Regulatory Guide 222 (RG 222) as part of a broader package of reforms designed to improve transparency around ownership, control and economic exposure in listed entities.
While much attention has focused on the introduction of the new Substantial Holding Notice (SHN) and the concept of Deemed Economic Interests (DEI), RG 222 remains one of the most important sources of practical guidance for firms responsible for monitoring shareholder disclosure obligations.
For investment managers, hedge funds, pension funds, custodians, brokers and compliance teams, understanding RG 222 is critical because identifying disclosure obligations is often more challenging than submitting the disclosure itself.
What Is ASIC RG 222?
RG 222 – Substantial Holding Disclosure and Tracing Requirements provides ASIC’s guidance on Australia’s shareholder disclosure framework and ownership tracing obligations.
The guide helps market participants understand:
- Substantial holding disclosure requirements
- Ownership tracing obligations
- Compliance expectations
- Reporting responsibilities
- Regulatory interpretation of disclosure rules
The updated version forms part of Australia’s enhanced beneficial ownership disclosure framework and supports the substantial holding reforms commencing on 4 December 2026.
Why Did ASIC Update RG 222?
Australia’s ownership disclosure framework has traditionally been centered around:
- Direct ownership positions
- Relevant interests
- Substantial holdings.
However, financial markets have evolved significantly. Investors increasingly gain exposure to listed entities through:
- Equity derivatives
- Structured products
- Prime brokerage arrangements
- Securities lending arrangements
- Synthetic investment structures
The updated RG 222 forms part of a broader effort to improve transparency around ownership and economic exposure within Australian markets, and tracing requirements.
What Topics Does RG 222 Cover?
The updated guidance focuses on several core areas.
Substantial Holding Disclosure
RG 222 explains ASIC’s expectations regarding substantial holder disclosures and the reporting framework supporting those obligations. This includes guidance supporting the new Substantial Holding Notice (SHN) framework introduced under Australia’s enhanced ownership disclosure regime.
Ownership Tracing
One of the most important objectives of RG 222 is to support ownership transparency.
Tracing requirements help identify in listed entities:
- Ultimate beneficial owners and
- Controller of interests
To enable this, the guidelines incorporate guidance on:
- Tracking notices, that allows a listed entity to require information from a person or entity who ultimately holds or controls a relevant interest in its securities
- A register of relevant interests records the identified holders, nature and extent of their relevant interest and the circumstances giving rise to the interest, supporting transparency of ownership and control.
ASIC is also introducing an index-based format for the register of relevant interests
Treatment of Derivatives and Short Positions:
The guidelines detail how derivatives and short positions must be treated for the purpose of substantial shareholding monitoring and reporting
- Derivatives: The new framework requires disclosure of deemed economic interest, including positions arising from physically and non physically settled derivatives based on the underlying securities exposure.
- In short, for a non physically settled derivative with a linear symmetric payoff, the deemed economic interest is the full notional number of underlying securities. Whereas for a derivative with a non-linear or asymmetric payoff, ASIC uses the below calculations:
- Derivatives delta X the full notional amount of the underlying securities
- Short positions: Offsetting short positions must also be disclosed, providing greater transparency over the holder’s overall economic exposure to the underlying securities.
Compliance Expectations
RG 222 also helps firms understand ASIC’s expectations regarding:
- Monitoring processes
- Disclosure controls
- Reporting responsibilities
- Governance arrangements
In practice, effective compliance requires firms to identify disclosure triggers accurately and consistently before reporting deadlines arise..
How Does RG 222 Relate to the New SHN?
RG 222 forms part of the regulatory framework supporting the new Substantial Holding Notice (SHN).
Australia’s enhanced ownership disclosure regime introduces a consolidated reporting framework designed to replace Forms 603, 604 and 605 with a new “Substantial Holding Notice (SHN).”
The SHN provides a new reporting structure, while RG 222 provides supporting regulatory guidance regarding how firms should interpret and comply with disclosure obligations under the new framework
Until 4 June 2027, an interest holder can satisfy the substantial holding notification requirements using either:
- New consolidated SHN
- 3 transitional forms corresponding to the existing 603, 604,605.
How Does RG 222 Relate to RG 5?
Many firms reviewing the Australian reforms will encounter both:
- RG 222
- RG 5
Although closely linked, they serve different purposes.
| Regulatory Guide | Primary Focus |
| RG 222 | Substantial holding disclosure and tracing requirements |
| RG 5 | Relevant interests, deemed economic interests and derivative exposure |
Together they provide much of the practical guidance supporting the enhanced disclosure framework.
Why RG 222 Matters for Investment Managers
The enhanced ownership disclosure framework creates operational challenges that extend well beyond regulatory interpretation. Many firms currently manage ownership monitoring using processes designed around direct ownership positions.
However, today’s investment structures often involve:
- Multiple portfolios
- Complex organizational structures
- Multiple investment strategies
- Multiple custodians
- Multiple counterparties
As a result, firms need to ensure their monitoring frameworks can:
- Aggregate positions accurately
- Apply appropriate calculations for derivatives and offsetting short positions
- Track relevant interests
- Identify disclosure trigger events
- Support tracing requirements
- Maintain audit trails
Securities Lending, Prime Brokerage and Tracing Challenges
Ownership tracing becomes significantly more complicated where positions move between:
- Custodians
- Prime brokers
- Securities lending programmes
- Multiple counterparties
These arrangements can involve separation between:
- Legal ownership
- Economic ownership
- Voting rights
For many firms, understanding ownership chains and tracing obligations may become increasingly important under the enhanced transparency regime.
Operational Challenges Firms Should Expect
One of the biggest implementation challenges is data fragmentation.
Ownership information frequently resides across:
- Portfolio management systems
- Order management systems
- Custodian records
- Compliance platforms
- Fund administration systems
- Prime broker data feeds
Maintaining a consolidated view of ownership and exposure can therefore become a significant operational challenge.
In many cases, identifying a reportable event will be more difficult than preparing the disclosure itself.
Why Spreadsheet-Based Disclosure Monitoring Is Becoming Harder
Spreadsheets can work effectively for relatively straightforward processes.
The challenge increases when a firm needs to manage:
Multiple jurisdictions + multiple portfolios + multiple entities + multiple instruments + changing regulatory requirements.
Manual processes can create risks including:
- Incorrect calculations
- Outdated thresholds
- Missed position changes
- Inconsistent aggregation
- Manual data-entry errors
- Missed deadlines
- Fragmented approval processes
- Limited auditability
The Australian reforms demonstrate why shareholder disclosure monitoring is increasingly becoming a data and operational control challenge, rather than simply a regulatory filing task.
What Should Firms Be Doing Now
With implementation now approaching, firms should review:
Can your existing controls identify both direct ownership and control data to cater to the tracing notices and registers of relevant interest?Are exposures aggregated consistently across funds, mandates, entities, capturing relevant interest also across lending, agency and prime brokerage arrangements?
- Are escalation, approval, and reporting workflows clearly defined? Can your organisation evidence:
- What position was identified?
- What data was used?
- What calculations were performed?
- Which rule was applied?
- Who approved the disclosure?
These are increasingly important questions under ASIC’s enhanced transparency framework.
