Ownership

CHESS-sponsored, issuer-sponsored or custodial: who holds your shares

With a CHESS-sponsored holding, your shares are recorded in your own name on ASX’s CHESS subregister, under a Holder Identification Number. With a custodial holding, a platform or custodian holds them on your behalf, sometimes in a shared account, and your rights can be different.

General information, not financial advice. How a particular platform holds shares is set out in its own documents. The official explainers are ASX’s page on CHESS and settlement and Moneysmart’s page on fractional share trading.

The way your shares are held decides three practical things: whether you are the legal owner, which rights come with the holding, and how easily you can move it to another broker. Two people can buy the same company’s shares on the same day, through different platforms, and end up holding them in quite different ways.

Three ways of holding, side by side

Drawn from ASX and Moneysmart. Each platform’s documents set out its own arrangement.
	CHESS-sponsored	Issuer-sponsored	Custodial or omnibus
Where it is recorded	On the CHESS subregister, through a sponsoring broker.	On the issuer-sponsored subregister kept for the listed company, usually by a share registry.	Held for you by the platform or a custodian, possibly in a shared account, or under an omnibus HIN.
Your number	A HIN: the letter X followed by ten numbers.	An SRN, usually starting with the letter I, and a different one for each company.	Your account with the provider.
Legal title	In your own name; ASX says you retain legal title.	Recorded under an SRN allocated to you by the company that issued the shares.	With an omnibus HIN, you are not the legal owner.
Statements	A CHESS holding statement from ASX for each security, at the end of any month in which the holding changed.	An issuer-sponsored holding statement from the share registry.	Ask the provider what it sends and when.
Moving it	ASX describes full portability of assets.	ASX notes that CHESS holdings avoid having to move shares across from an issuer-sponsored account before trading.	You may not be able to transfer to another platform the way you could with directly owned shares.

CHESS and the HIN

CHESS stands for Clearing House Electronic Subregister System. It settles trades and keeps an electronic subregister recording ownership of shares bought and sold by clients of market participants. ASX’s investor FAQ says that to buy or sell shares on ASX you need to use a CHESS sponsoring broker.

Your Holder Identification Number is issued by ASX when you become a client of a broker, and all the shares you buy through that broker are connected to it. ASX lists what this gives an investor: holdings in your own name; a consolidated view of your broker-sponsored holdings under one HIN; and standard monthly statements when something changes. When your address or other details change, you may only need to tell your sponsoring broker (or brokers).

You will find the HIN on the CHESS “Welcome” letter and on every CHESS holding statement after it. If you have neither, ASX says to ask your sponsoring broker. Statements can come by post or electronically through ASX’s CHESS Statements Portal, but only after your broker opts you in with your email address.

One detail matters if you move house. ASX does not hold or change investors’ personal details; updating your address with your sponsoring broker is your responsibility.

Issuer-sponsored holdings and the SRN

Some shares sit not on CHESS but on the issuer-sponsored subregister, kept for the listed company and, in most cases, administered by a share registry. Each company gives you a separate Securityholder Reference Number, so a person with shares in five companies this way has five SRNs.

The share registry sends a holding statement showing your SRN. If you cannot find one, Moneysmart’s advice is to contact the registry and ask for it.

Custodial and omnibus arrangements

Some providers hold shares for their clients instead of registering each holding in the client’s name. Moneysmart describes two versions.

The first is the omnibus HIN. To offer lower brokerage, some entities hold shares under one omnibus HIN rather than an individual HIN for each client. Investors in that case are not the legal owner of their shares and have fewer protections if something goes wrong, including the ability to claim against the National Guarantee Fund.

The second comes with fractional share trading, where you can buy part of a share. The shares may be held on your behalf by the platform or a custodian in a shared account. Depending on the platform you might directly own a fraction of a share, or hold your investment through a pooled or custodial arrangement. Moneysmart lists what can differ from direct ownership:

Voting rights. You may not have the same votes as a direct shareholder.
Corporate actions. Your part in shareholder activities may be different.
Transfers. You may not be able to move the investment to another platform as you could with directly owned shares.
Execution. The price you get may not always match the market price at the moment you place the order.

Moneysmart’s example

When the shares cannot follow you

Moneysmart tells of an investor who built a sizeable holding over five years with a fractional trading provider. When the provider’s ongoing fees rose and she wanted to change brokers, the provider would not transfer the fractional part of her holding. Her only way out was to pay a fee to sell, pay capital gains tax on the profit, and reinvest through the new broker.

Selling to move is a disposal, and disposing of shares can trigger capital gains tax. Page 7 explains capital gains tax on shares.

Questions to ask before you open an account

The answers are in a provider’s documents, or it can tell you. Moneysmart frames the central one as: will I own the investments I buy, or will the provider own them, and what does that mean if I want to sell them? Around it sit a few more:

Will my shares be held on a HIN in my own name, or under the provider’s name?
If I leave, can my holdings be transferred to another broker, and is there a cost?
Will I receive CHESS holding statements from ASX, or the provider’s own reports?
Will I be able to vote and take part in corporate actions?
