List company members and shareholders

List the shareholders of an Australian proprietary company by ACN, with share class, number held, beneficial ownership, joint holders and addresses.

Company members

Members are the shareholders of a company. For proprietary companies ASIC records, for each class of shares, the top twenty members ranked by the number of shares held, with each member's name, address, the number of shares, whether they are held beneficially and whether they are fully paid. Members can be people or organisations, and a single holding can be held jointly by several members. This endpoint returns those shareholdings as structured records, the primary source for identifying who owns an Australian private company. The data comes from a company extract you have already purchased with POST /v1/companies/{id}/extracts and is read back for free, as described in the purchasing guide.

Response fields

Field	Type	Description
`object`	string	Always `list`.
`data[]`	shareholding[]	One record per holding. A joint holding is one record with several holders.
`data[].object`	string	Always `shareholding`.
`data[].classCode`	string	Share class code, matching `classCode` in share capital.
`data[].numberHeld`	integer	Number of shares (or scheme interests) in the holding.
`data[].beneficiallyOwned`	boolean or null	`true` when the member holds the shares beneficially, `false` when held on trust or as nominee for someone else. `null` when ASIC has no record.
`data[].fullyPaid`	boolean or null	Whether the shares in the holding are fully paid.
`data[].status`	code	`C` current or `E` ceased.
`data[].jointHolding`	boolean	`true` when two or more members hold the shares jointly; `holders` then has more than one entry.
`data[].holders[]`	object[]	The member or joint members. Up to 999 holders per holding.
`data[].holders[].party`	party	`type` `person` with `person` name details, or `organisation` with `number`, `numberType`, `name` and `abn`. ASIC does not record birth details for members, so `birth` is always `null`.
`data[].holders[].address`	address or null	The member's address as notified. Joint holders often share one address.
`data[].sourceDocument`	object or null	Document that last changed the holding, typically a Form 484 (sub-form 484E, change to members register) or an annual return with an `AR` qualifier.
`hasMore`	boolean	Always `false`.
`nextCursor`	string or null	Always `null`.
`totalCount`	integer or null	`null`.
`extract`	object	The extract the data was read from: `id`, `type` (`current` or `historical`), `purchasedAt` and `asOf`. Share transfers lodged after `asOf` are not reflected.
`meta.billable`	boolean	Always `false`. Reading an extract you hold is free.
`meta.product`	string or null	Always `null`.
`meta.requestId`	string	Request identifier.

Notes from the ASIC register

Snapshot. The members list reflects the register at extract.asOf. A transfer notified after that date appears only in a newly purchased extract.
Only the top 20 members per class. ASIC's own note reads: For each class of shares issued by a proprietary company, ASIC records the details of the twenty members of the class (based on shareholdings). The details of any other members holding the same number of shares as the twentieth ranked member will also be recorded by ASIC on the database. Where available, historical records show that a member has ceased to be ranked amongst the twenty members. This may, but does not necessarily mean, that they have ceased to be a member of the company. A ceased holding in a historical extract can therefore mean the member simply dropped out of the top twenty.
Public companies. Public companies have not been required to notify ASIC of their members since 1 July 1998, so the list is usually empty for APUB companies and listed companies. Their registers are held by the company or its share registry.
Beneficial ownership. beneficiallyOwned: false indicates the recorded member holds the shares for someone else, such as a trustee or nominee. ASIC does not record who the beneficial owner is.
Joint holdings. Joint holders are listed together in one holding with jointHolding: true. Each holder has their own name and address.
Corporate members. For a corporate member party.organisation.number is the ACN where the member is an Australian company; for foreign or unregistered entities numberType may be NUMBER (a plain registration number) or the number may be null.
No birth details. ASIC records names and addresses for members but not dates of birth, so two members with the same name cannot be distinguished from this data alone.
Unknown flags. Records migrated from state registers before 1991 may have beneficiallyOwned or fullyPaid set to null.
