Appendix 3Y Errors: The Compliance Cleanup That Gets Noticed...

This post is written for chairs, directors and CFOs of ASX-listed entities. If you want to understand your legal exposure on this issue, contact JR3 Legal.

Every ASX-listed company secretary knows the Appendix 3Y obligation. A change in a director's notifiable interest - shares bought on market, options exercised, securities issued, and this form must be lodged within five business days under Listing Rule 3.19A.2.

Simple enough.

The problem is not understanding the obligation. The problem is the template, the timing, and a set of assumptions about what counts as disclosure.

Why the obligation exists

The Appendix 3Y regime sits alongside trading blackout policies for a reason. Directors are, by definition, periodically in possession of material non-public information - about earnings, transactions, regulatory outcomes, or operational developments that have not yet been disclosed to the market. That is not improper; it is the nature of the role. But it creates a structural information asymmetry between directors and the market.

The market responds to director trading accordingly. A director purchase is widely read as a buy signal - an insider with genuine visibility into the business putting their own capital to work. A sale reads as the reverse, even when the reasons are entirely personal. Right or wrong, that signal moves. Prompt, accurate disclosure of every change in a director's interest is what allows the market to assess those signals on a fully informed basis. It is the same rationale that underlies closed period restrictions under Listing Rule 12.12 - the difference being that blackout policies restrict the trading, while the Appendix 3Y obligation ensures that what does trade is visible to the market immediately and accurately.

Treating the lodgement as a routine administrative task misunderstands what the obligation is actually doing.

How errors happen - the four patterns

After seeing these corrections across small and mid-cap ASX entities, the failure modes are consistent.

The template carry-forward error. The company secretary maintains a standing Appendix 3Y for each director — the last notice lodged, saved and updated each time a new change occurs. The risk is not just numerical. In September 2025, Aspermont Limited (ASX: ASP) issued a correction after a filing for Director Ajit Patel incorrectly referenced another director, Alex Kent - the name carried forward from the previous template. If a basic biographical field can survive undetected into a public announcement, so can an incorrect security balance, a wrong holding vehicle, or a misclassified option tranche.

The cluster error. Options granted to the board at the same time, typically at an AGM - often expire at the same time. On 19 March 2025, Barton Gold Holdings Limited (ASX: BGD) released an announcement titled "Amended Director's Interest Notices," correcting notices filed just two days earlier for three directors simultaneously: Kenneth Williams (Non-Executive Chairman), Alexander Scanlon (Managing Director and CEO), and Christian Paech (Non-Executive Director). All three (3) corrections related to the expiry of unlisted options on 15 March 2025 - the same tranche, the same date, the same error propagated across the entire board. The complexity of the indirect holdings involved - superannuation funds, family trusts, and spousal holdings held through multiple corporate vehicles made the miscalculation easy to make and difficult to catch before lodgement. A single conceptual error produced a bundle of incorrect public notices simultaneously.

The settlement lag error. The five-business-day clock under Listing Rule 3.19A.2 starts on the date of the trade, not the settlement date. In December 2025, Vulcan Steel Limited (ASX: VSL) responded to an ASX query letter after an Appendix 3Y for Director Adrian Casey was lodged one day late. The company secretary had set a diary reminder based on an assumed trade date of 7 November 2025. The actual trade date was 6 November.

By the time the contract note was received on 14 November and the Appendix 3Y lodged at 11:12am, the deadline of 13 November had passed by one day. The contract note confirmed the trade on 6 November and settlement on 10 November - the settlement lag distinction was explicit in Vulcan Steel's response to ASX. Companies that track from settlement rather than trade date are routinely one to two days late without realising it.

The public event fallacy. When securities are issued to directors pursuant to a resolution passed at a general meeting, being an event already announced via Appendix 2A and Appendix 3B can contribute to company secretaries sometimes treating these lodgements as covering the director-specific disclosure.

In August 2024, Polymetals Resources Limited (ASX: POL) responded to an ASX query under Listing Rule 18.7 after an Appendix 3Y for Director David Sproule was lodged late. If the correction triggers an ASX query letter, the process from there follows the same path as any other compliance inquiry. The company secretary explained that because the shares had been issued pursuant to a shareholder resolution, an Appendix 3B, Appendix 2A, and cleansing notice had already been lodged - and the Appendix 3Y was overlooked in the process. ASX does not accept this. The Appendix 3Y obligation under Listing Rule 3.19A is distinct from the entity's general issue notification obligations and is not satisfied by any other form.

How errors typically surface

Most Appendix 3Y errors are discovered by the company itself - not proactively, but during the preparation of audit schedules for the annual report. The finance team or company secretary is pulling together the director interest disclosures for the auditors' related party transaction review, reconciling successive Appendix 3Y notices against the company's actual share registry records, and realises the balances do not match. At that point, months or years may have passed since the incorrect notices were lodged.

The company then has to self-correct. It lodges the corrected Appendix 3Y notices - individually, each one a public announcement on MAP. If the history is long, or if multiple directors are affected as in the Barton Gold example, that is a cluster of corrections released simultaneously with a cover letter explaining what went wrong, how it was identified, and what the company will do to prevent recurrence.

The auditors then review the corrections as part of their procedures. The fact that the corrections were necessary, and the reason why, becomes part of the audit file. The public record shows that the company's director disclosure controls were not tight enough to catch these errors before audit preparation forced them to the surface.

What ASX does when it finds the error first

If ASX identifies a discrepancy before the company self-corrects, it issues a query letter under Listing Rule 18.7. The letter is standardised: it asks why the notice was late or inaccurate, what arrangements the entity has in place under Listing Rule 3.19B, whether those arrangements are adequate, and what steps will be taken to prevent recurrence. The entity's response is released to the market under Listing Rule 18.7A. ASX also reserves the right to suspend trading under Listing Rule 17.3 if the response is not provided by the deadline specified in the letter - typically within two to three business days.

The Polymetals Resources query letter from 30 July 2024, directed to Company Secretary John Haley, required a response by 9:00am on 2 August 2024 and carried an explicit suspension warning. The response which acknowledged the oversight, confirmed the LR 3.19B arrangements in place, and noted that all directors had been reminded of their obligations by email was released to the market on MAP alongside the ASX's query letter.

The root cause in both cases

Late notices trace back to the director-to-company notification step. Listing Rule 3.19B requires the entity to have arrangements in place with each director to ensure timely disclosure. In practice those arrangements are often informal and not enforced systematically. When a trade occurs and the director does not notify promptly - or where, as in the Vulcan Steel case, a notification email fails to send - the clock runs regardless.

Errors trace back to template maintenance, the complexity of indirect holdings through family trusts and corporate vehicles, and the absence of a reconciliation step before lodgement. Errors also cluster around high-volume periods - immediately after an AGM, during or after a capital raise, when multiple ASX releases are going out simultaneously and the company secretary's administrative capacity is stretched. These are precisely the moments when the reconciliation step is most likely to be skipped.

The fix is a system, not a reminder

Three things would eliminate most of these issues.

First, a standing director disclosure agreement under LR 3.19B that sets a specific notification timeframe - not "as soon as practicable" but within 24 hours of a trade or issue - with a named contact and a documented escalation if notification does not arrive.

Vulcan Steel's post-incident process - reminders sent within two working days of consent to trade, is a reasonable model, though starting the clock from consent rather than trade date still carries risk.

Second, configure the share registry to send automatic notifications to the company secretary and chairman whenever a movement is recorded against a director's holding. Most registries support this - it is a setting, not a system upgrade. It does not replace the director's obligation to notify, but it provides an independent trigger: if the registry flags a movement before the director has notified, the company secretary knows to follow up before the five-business-day clock expires.

Third, a live interest register for each director, reconciled against each new Appendix 3Y before lodgement, rather than a template updated in isolation. The Barton Gold corrections - - three directors, complex indirect holdings, options expiring simultaneously, would have been caught by a reconciliation step that compared the prior notice balance against the current register before the amended notices were filed on 17 March 2025.

None of these is complicated. The first is a document. The second is a registry setting. The third is a discipline. All three are easier than explaining to ASX, and to the market, why the history needed correcting.
