A stapled security is two or more separate instruments — on SGX, characteristically a REIT unit stapled to a unit in a registered business trust — that trade as one counter and cannot be transferred or realised apart from one another. That indivisibility, together with the fact that a business trust unit is a beneficial interest in a trust rather than a share in a company, is what makes the stapled form its own collateral question on the Singapore Exchange. It does not put the instrument out of reach as collateral; it changes how the security package is documented and how a realisation would have to work.
Key takeaways
- Two instruments, one counter. A stapled security is legally two or more components, each with its own constitutive document and governing body, quoted and settled on SGX as a single line.
- A unit is a beneficial interest. A unit in a registered business trust under the Business Trusts Act 2004 is a beneficial interest in trust property held by the trustee-manager — not a share in a corporation.
- One trustee-manager, not a trustee and a manager. A single company both holds the trust assets and runs the business, subject to statutory duties, and can be removed by unitholders holding not less than 75% of the voting rights present and voting, alongside the replacement machinery in the Act and the trust deed.
- The charge covers the whole staple. One security agreement, one CDP line, both components — a charge over one leg alone would secure something the borrower cannot transfer, and a lender could not realise, on its own.
- Enforcement moves both legs or neither. The components are transferable only together, so realisation is designed around indivisibility rather than a choice of which leg to sell.
Singapore is the natural home of this instrument. The Business Trusts Act 2004 gave the market a registered vehicle for owning and operating a business through a trust, and the exchange has since listed both standalone business trusts and stapled groups — a category our sector coverage has named alongside S-REITs from the beginning. This note sets out what the collateral legally is, who stands behind it, where the charge attaches, what the register and CDP actually show, and why a lender cannot take one leg and leave the other. It is a general description of the framework, not legal advice.
What a business trust is, and what makes a security stapled
Start with the vehicle. A registered business trust is constituted under the Business Trusts Act 2004 and registered with the Monetary Authority of Singapore. It is neither a company nor a fund: it owns and operates a business through a trust structure, and what an investor holds is a unit — a beneficial interest in the trust property, carrying the economic entitlement and the votes the trust deed confers, but not the same statutory rights a shareholder has under the Companies Act 1967. The Business Trusts Act 2004 gives unitholders a set of analogous statutory protections of its own, drawn on company-law lines but owed by a different party and exercised in a different way.
Stapling is a separate idea layered on top: two or more instruments issued by different entities are contractually tied so that they are held in fixed proportions and can only change hands together. On SGX the familiar shape is a REIT unit stapled to a unit in a registered business trust — a passive asset-owning vehicle on one side, an operating business on the other, offered as a single investable claim on both. In other markets a company share is stapled to a trust unit in the same way. The legal consequence is two issuers, two governing documents, two sets of distributions, one instrument, and no ability to separate them.
The classification matters. Units in a business trust fall within the definition of securities in section 2(1) of the Securities and Futures Act 2001, while units in a REIT are units in a collective investment scheme — a different limb of the same Act, and the reason an S-REIT sits under the MAS Code on Collective Investment Schemes and its Property Funds Appendix while a business trust does not. A stapled security can straddle two characterisations at once, which is why the constitutive documents are read before the term sheet is written.
The trustee-manager, and the 75% vote that can remove it
The Business Trusts Act 2004 does something no company law does: it puts the trustee and the manager in the same body. The trustee-manager is a single company that holds the trust property on trust for the unitholders and, at the same time, manages and operates the business. In an S-REIT the trustee and the manager are separate and independent, and each is a check on the other. In a registered business trust that check is replaced by statute: the Act imposes duties on the trustee-manager to act honestly and in the interests of the unitholders as a whole, to exercise reasonable diligence, and to give priority to the unitholders' interests where they conflict with its own.
For a lender this is not an abstraction. The party operating the business and the party holding the assets are the same entity, and the unitholders' principal structural remedy is removal — under the Act, by a resolution of unitholders holding not less than 75% of the voting rights of all unitholders present and voting. That is not the only route out: the Act and the trust deed also carry machinery for a trustee-manager to resign or be replaced, and the Act gives unitholders statutory remedies of their own against it. But the 75% resolution is the one that sets the balance of power in the vehicle, and a charged holding, however substantial, is one voice inside that arithmetic; it is not a lever over the operator. The practical consequence is that the collateral is assessed through the trustee-manager as well as through the counter.
What the stapling deed typically settles
- Fixed proportions — each stapled security comprises a defined number of each component, and the ratio survives issues and consolidations.
- Transfer only together — the components cannot be transferred or registered separately for so long as the stapling subsists.
- De-stapling gates — the circumstances in which the staple can be undone, and the approvals required, typically including resolutions of both sets of holders.
- Corporate-action coordination — how issues, consolidations and distributions at one component are matched at the other.
A charge over a unit is a charge over a beneficial interest
This is where the form bites on the documentation. Charging an ordinary SGX share charges a shareholding: an interest in a corporation, recorded in a register of members, held in the ordinary course through the book-entry system operated by The Central Depository (CDP). Charging a business trust unit charges a beneficial interest in trust property. Economically the two are close cousins; legally they are not the same, and the difference shows up in how the security is taken, in the register, and in enforcement.
On taking the security: security over a listed unit is not ordinarily taken by transferring legal title into the lender's name. The collateral is moved into, or already sits in, an account with the designated custodian, over which the lender takes security, while beneficial ownership is preserved. The charge attaches to the beneficial interest and to the account through which it is held — a CDP securities account in the holder's own name, or a broker or custodian sub-account where the intermediary is the holder of record. What is then needed to make that security effective and to fix its priority — including notice to the custodian or account provider, the identification of the charged units, and any filing required where the chargor is itself a company rather than an individual — depends on the custody route and on who the chargor is, and is settled with your own Singapore counsel before funding. The charge is security, not a sale; beneficial ownership is preserved and the holding is released on repayment.
On the register: the trustee-manager keeps a register of unitholders, but for an SGX-listed trust the name in it is CDP's. CDP is the holder of record behind that listed register and maintains the Depository Register that sits beneath it, and the depositor named in the Depository Register is treated as the unitholder for most purposes; where the investor holds through a custodian, the depositor is the intermediary and there is a further layer of books at that intermediary. Either way, a lender cannot secure its position by having its own name written onto a unit register. What can be given is identification of the collateral in a defined account, control over dealings in it, and the apparatus that turns that control into a realisation route.
| Consideration | Ordinary SGX share | Unit in a registered business trust | Stapled security |
|---|---|---|---|
| What you hold | Shares in a company | A beneficial interest in trust property | Two or more components, held as one |
| Principal governing instrument | Companies Act 1967 and the constitution | Business Trusts Act 2004 and the trust deed | Both, plus the stapling deed |
| Who runs it | A board of directors | A single trustee-manager | Each component's own governing body |
| SFA 2001 classification | Securities | Securities — units in a business trust | Each component on its own footing |
| Transferable on its own | Yes | Yes | No — the components move together |
| What the charge attaches to | The shareholding, held through CDP | The unit as a beneficial interest | Both components as one package |
| Realisation route | Sale of the shares | Sale of the units | Both legs together, or not at all |
Enforcement: no leg can be realised alone
The third difference is the decisive one. A lender enforcing against an ordinary shareholding has a mechanical question — how much, over what period, into what liquidity. Against a stapled security it has that question and a prior one: it may only dispose of the security as a whole. The stapling deed and the constitutive documents make the components transferable only together for so long as the stapling subsists, and SGX quotes only the stapled counter, so there is no order book for a single leg to sell into.
A staple is not a portfolio of two positions. It is one position that happens to have two legal halves — and it can only be financed, and only be realised, as one.
Two consequences follow. First, the security package is drafted as one: a single agreement identifying both components, one collateral account, one set of release provisions, and disposal mechanics that assume indivisibility. A lender cannot design a partial release of the "safer" leg, because there is no such thing. Second, the credit view is taken on the stapled counter as it actually trades — its own free float, turnover and volatility — not on a notional sum of the components; those drivers are set out in our note on how LTV is set on an SGX counter, and a narrower realisation route is priced and structured rather than ignored, as we describe in recourse profiles. Size matters as well as form: a stapled block large enough to carry a holding across a control threshold on a disposal raises questions under the Singapore Code on Take-overs and Mergers, which reaches listed business trusts and REITs as well as companies — the subject of our note on the 30% threshold, and a point settled with counsel before a facility is put in place rather than at the moment of enforcement. Transactions are typically structured from SGD 5 million upward, and an indicative view follows a review of the actual counter and holding.
Distributions across two components
A stapled security usually presents a single distribution figure, but that figure is the sum of two decisions taken by two different bodies. The REIT component declares its distribution under its own constitutive document and through its own manager and trustee; the business trust component declares its distribution through the trustee-manager under its own trust deed. They are commonly declared together and paid on a common record date, which is why a holder experiences one payment — but they are not one payment in law, and the two legs need not have the same capacity to pay.
The two legs do not pay under the same constraint. What an S-REIT pays out is shaped by the tax-transparency distribution discipline that applies to it, and by the Property Funds Appendix regime under which it operates. A registered business trust may distribute out of operating cash flow, subject to the trustee-manager's judgement on solvency, and is not bound by that discipline, while a company distributes out of profits available for distribution. The income of a stapled security can therefore be assembled from two streams with different legal constraints, and the documentation has to address each on its own terms — who receives it during the term, how it interacts with servicing, and what happens if one component pays while the other does not. It is the discipline we describe for REIT distributions in S-REIT financing, applied twice. Corporate actions double in the same way: an issue, consolidation or capital return can originate at either component, and the stapling arrangement generally requires the other to be adjusted so the ratio survives.
How the facility is built around the constraint
None of this puts a stapled counter beyond a share-backed facility; it changes the order in which the work is done, and — like any counter — the terms follow a review of the specific name and holding. The constitutive documents — trust deed, constitution and stapling deed — are read first, by the borrower's own Singapore counsel, because the transfer restrictions and de-stapling gates live there and nowhere else. The security package is written once, over both components and the account holding them, with disposal and release mechanics drafted on the basis that the legs move together.
The disclosure position is confirmed in parallel. A substantial interest in the units of a registered business trust engages a disclosure discipline of its own under the Securities and Futures Act 2001, running in parallel to the substantial-shareholder regime that applies to a listed corporation but with its own addressee — notification is made to the trustee-manager, which announces the interest to the market — rather than to a company. It is the analogue of the regime we describe in our note on substantial-shareholder disclosure under the SFA 2001. Which discipline reaches a particular stapled holding, and on what timetable, is confirmed for your own position by your own Singapore counsel. The listed group's own continuing obligations, including the Rule 703 duty to announce material information and the corporate disclosure policy in Appendix 7.1 of the SGX Listing Manual, administered by SGX RegCo and filed through SGXNet, fall on the entity and its trustee-manager, not on the holder.
We act as arranger and introducer. Any disclosure or regulatory obligations, and the reading of any trust deed or stapling deed, are a matter for your own Singapore legal counsel, engaged in parallel; we do not provide legal or regulatory advice and we are not a law firm. What we do is make sure the instrument you actually hold — not the one a standard share-charge template assumes — is the instrument the facility is built around. Our process sets out where that review sits on the path from first conversation to funding.
