One way for a controlling shareholder to fund a rights issue is to borrow against the SGX shares it already holds, rather than sell them. A stock loan pays for the shareholder's entitlement, and the new shares can join the collateral on the facility's terms, keeping the stake whole without the signal a sale sends.
Key takeaways
- The rules address the undertaking. SGX's Mainboard Rules do not use the phrase "irrevocable undertaking", but Rule 877(9) calls for a financial institution's confirmation of resources when a substantial shareholder undertakes to subscribe.
- Funding is arranged early. The Rule 877(9) confirmation accompanies the issuer's listing application, so the facility needs arranging early, not at the acceptance deadline.
- The window is short. On SGX's expected timetable for a renounceable issue, nil-paid rights trade from the third market day after the record date, and acceptances close on or after the thirteenth.
- Charged shares need agreed instructions. The facility and custody documents set how rights on charged shares are taken up or sold and how the new shares join the collateral; terms vary by facility.
- Control and disclosure are separate checks. A take-up that lifts your percentage can engage the Take-over Code and the 5% notification regime, so both are confirmed with Singapore counsel.
A rights issue puts one question to every shareholder at once: pay for the new shares or accept dilution. For a controlling shareholder the sum is large and the timetable short, and selling shares to raise the cash shrinks the stake the subscription is meant to protect. This note sets out what the SGX listing rules say, how a share-backed facility fits around them and what must be agreed for shares already charged.
Why do controlling shareholders give irrevocable undertakings?
Controlling shareholders give irrevocable undertakings to bind themselves to take up their entitlement before the issue opens. The issuer knows much of the issue is spoken for, and the shareholder's stake is protected from dilution. The SGX Mainboard Rules speak of a substantial shareholder who "undertakes to apply".
Under Mainboard Rule 877, where a substantial shareholder undertakes to apply for its entitlements or excess rights shares, the issuer submits "a confirmation from a financial institution that the substantial shareholder has the necessary financial resources" (Rule 877(9)). In the usual steps in Rule 871(2), the Rule 877 documents go to SGX with the additional listing application when the issue is announced. We have not found an equivalent in the Catalist Rules; confirm the position with counsel.
Whether to underwrite is generally for the issuer to decide, under Rule 817 of the Mainboard rules on rights issues (the Catalist rule is the same), and the announcement must say whether the issue will be underwritten (Rule 814(1)(g)). A fee changes the position: where a controlling or substantial shareholder is paid a sub-underwriting fee to take up its entitlement or part of the excess, Practice Note 8.2 (Catalist Practice Note 8B) requires specific shareholders' approval.
If you also apply for excess rights shares, that part of the application is the least certain. In allotting them, directors and substantial shareholders with control or influence over the issuer, or board representation, "rank last in priority" (Mainboard Rule 877(10); Catalist Rule 814(3)). It is sensible to size the facility around the entitlement first.
A full take-up keeps your percentage only if the whole issue is taken up. If other holders do not take up their rights in full and nobody takes up the shortfall, fewer new shares are issued and your percentage rises. For an issue that is not underwritten, Rule 820(2) on both boards says SGX may permit the issuer to scale down a shareholder's application, to avoid that shareholder incurring a mandatory bid obligation under the Take-over Code.
Rule 14.1 of the Singapore Code on Take-overs and Mergers requires a general offer, except with the Securities Industry Council's consent, when an acquisition takes a person and its concert parties to 30% or more of the voting rights, or when a holder already between 30% and 50% acquires more than 1% in any six months. Note 14 on Rule 14.1 asks for the Council to be consulted where rights-issue shares are allotted provisionally but not yet issued.
Whether a particular take-up engages the Code turns on the facts, including the holdings of any concert parties, and is a question for your Singapore counsel and, where needed, the Council. Our note on the 30% takeover threshold sets out how the Code meets a share-backed facility.
A rise in your percentage can also be notifiable. Under section 136 of the Securities and Futures Act 2001, a substantial shareholder gives written notice to the company within two business days after becoming aware of a change in the percentage level of its interest, a figure rounded down to the next whole number. Our note on substantial-shareholder disclosure covers the regime and how a charge interacts with it.
How does a stock loan fund the subscription?
You charge SGX shares you already hold as collateral and draw cash against them to pay for your rights shares. For a Mainboard issue, an undertaking to subscribe calls for a financial institution's confirmation of your resources, submitted with the issuer's listing application, so the facility needs arranging early.
The facility is sized to the subscription: your entitlement at the issue price, plus any excess application you intend to fund. The advance against the charged shares is set from the same factors as for any SGX counter, including liquidity, volatility and concentration, as our note on how LTV is set explains. Transactions are typically from SGD 5 million upward.
Drawdown is timed to the acceptance deadline in the issuer's timetable. The facility agreement records the purpose of the loan, and how the subscription monies are paid, whether through the custodian or from your own account, is agreed with the lender and custodian. Terms vary by facility.
The new shares cannot secure the drawdown that pays for them: the issuer allots and issues them only after the close (Rule 871(2)(h)), so the existing shares carry the facility until then. Once they are issued, the documents decide whether they fall within the existing charge automatically or are added by a further document, and whether they change the advance available. Our note on CDP custody and share charges explains why such corporate actions are agreed in advance.
Charging the new shares may itself be disclosable. Where the listed group's own borrowings contain a specified condition, a controlling shareholder's share pledging arrangements are notified to the issuer and announced, as our note on SGX Rule 728 and share pledges explains. Whether adding new shares to an existing pledge calls for a fresh notification is a question for counsel.
What the structure avoids is a sale. Selling part of the holding, or selling some nil-paid rights to pay for the rest, leaves you with a smaller stake; borrowing leaves it whole. A disposal by a controlling holder is also read by the market, the point our note on quiet liquidity makes.
What happens to nil-paid rights on charged shares?
Nil-paid rights on charged shares arrive through the account in which those shares are held, like any other entitlement. The facility and custody documents decide who instructs a take-up or sale, and whether the rights or the new shares become collateral. Terms vary by facility.
Your entitlement is fixed by your holding at the record date, which the listing rules define as the date an issuer fixes for determining entitlements to rights and other distributions. Where the charged shares sit in a custodian sub-account, CDP Depository Rule 6.8 requires the depository agent to distribute rights received from an issuer through CDP to sub-account holders "in accordance with their respective holdings" at the record date.
Acceptance follows the same route. SGX's user guide for applying for rights through its Investor Portal states that shareholders holding through a finance company or depository agent must go through those intermediaries, and that applying directly to CDP for such shares may be rejected. For charged shares held through a custodian, allow for the custodian's own deadline for instructions.
Where the charged shares sit in a CDP securities account in your own name, the issuer's application forms come to you, and the documents set how you act on them while the charge is in place.
Four points are worth settling before the record date: whether the nil-paid rights themselves are charged; who may instruct the custodian to accept or sell them; where any sale proceeds go; and whether the new shares fall within the charge once issued. Agreeing them in advance avoids negotiating against a deadline only a few market days away.
Selling is possible only in a renounceable issue. Mainboard Rule 816 makes renounceable rights the default, transferable "in part or in whole in favour of a third party", and allows a non-renounceable issue only with specific shareholders' approval or, under a general mandate, at a discount of not more than 10% to the weighted average price for the full market day on which the issue is announced. The Catalist rule is the same.
How does the timetable work?
SGX's expected rights issue timetable counts market days from the record date, D. In a renounceable issue, application forms go out and nil-paid trading starts at D+3, trading ends on or after D+9, and acceptances close on or after D+13. The issuer's own timetable sets the actual dates.
Mainboard Rule 823 requires an issuer to observe any timetable SGX publishes, and Practice Note 8.1 sets the expected one. On Catalist, Rule 823 also requires a proposed timetable to be given to SGX, having regard to Practice Note 8A, which sets the same expected dates. Since 6 August 2026, both notes show acceptances opening at D+3, alongside nil-paid trading.
In a non-renounceable issue there is no nil-paid trading, and acceptances close on or after D+9. A market day is a day on which SGX is open for securities trading.
Before the record date, the rules set the usual order of steps but no period between them. The issuer announces promptly (Rule 814), SGX reviews the additional listing application, shareholders approve where required, and no record date may be fixed until SGX has approved the issue (Rule 821; on Catalist, until SGX has issued a listing and quotation notice).
Two rules turn on the start of ex-rights trading. From then, a rights issue that is not underwritten cannot be withdrawn (Rule 820(1)), and a force majeure clause in an underwriting agreement cannot be invoked (Rule 818). Funding that depends on conditions should have them satisfied by that point.
| Stage | What the SGX rules say | Loan step (general practice; terms vary by facility) |
|---|---|---|
| Announcement | The issuer announces promptly, including the allotment ratio and whether the issue is underwritten (Rule 814(1)), and submits its additional listing application with the Rule 877 documents (Rule 871(2)(a)). | Facility terms settled early enough for a financial institution to confirm your resources, if you have undertaken to subscribe (Mainboard Rule 877(9)). |
| Approval and record date fixed | SGX decides on the application and shareholders approve if required (Rule 871(2)(b) and (c)). No record date until SGX has approved the issue (Rule 821); on Catalist, until SGX issues a listing and quotation notice. The rules set no period for this stage. | Facility and custody documents completed, including instructions for the rights on charged shares. |
| Record date (D) | Entitlements are fixed by holdings at the record date. | The entitlement on charged shares follows the charged holding; a depository agent passes rights to sub-account holders in line with record-date holdings (CDP Depository Rule 6.8.1(a)). |
| D+3 | Application forms go to CDP account holders, and provisional allotment letters to CDP and registered holders (Rule 822: within 3 market days). Nil-paid trading and acceptances begin (Practice Note 8.1). | Take-up or sale instructions given through the account where the charged shares sit. |
| On or after D+9 | Last day for trading nil-paid rights. In a non-renounceable issue, last day for acceptance. | Any sale of rights completed; proceeds dealt with as the documents provide. |
| On or after D+13 | Last day for acceptance in a renounceable issue (Practice Note 8.1). | Loan drawn and subscription paid through the right channel before the deadline. |
| After the close | The issuer allots and issues the new shares, which are listed (Rule 871(2)(h)). | New shares join the collateral as the charge documents provide; disclosure checked with counsel. |
If the start of nil-paid trading is expected to be delayed, the issuer must announce it no later than 4pm on the market day before (Rule 871(2)(g)). A facility that can be drawn only on the final acceptance day leaves no room for a delay at the custodian, the paying bank or the issuer.
This is general information on how a rights issue and a share-backed facility fit together, not legal advice. Any disclosure, take-over or other regulatory obligations are a matter for your own Singapore legal counsel, engaged in parallel; we act as arranger and introducer and do not provide legal or regulatory advice.
