Convertible Notes in Singapore: Guide for Founders and Investors

A convertible note is an interest-bearing loan that converts into equity at a future priced round, making it the preferred bridge instrument when Singapore startups need capital but cannot yet agree on a valuation.

Three immediate actions before you proceed:

Founders: Confirm your company has current section 161 shareholder authority to allot conversion shares, and model your cap table against the note’s valuation cap before signing.
Investors: Verify the discount rate, valuation cap, and fallback repayment terms in the event conversion never occurs. Maturity without a clear redemption right is a common gap.
Lawyers: Check whether the offer qualifies for a Securities and Futures Act (SFA) private-placement or small-offers exemption, and confirm the ACRA Return of Allotment timeline is built into the closing checklist.

Three regulators govern the lifecycle of a convertible note in Singapore: the Accounting and Corporate Regulatory Authority (ACRA) for corporate filings, the Monetary Authority of Singapore (MAS) for securities-law compliance, and the Inland Revenue Authority of Singapore (IRAS) for tax and stamp duty. Each touches a different stage of the transaction, and missing any one of them creates legal or financial exposure.

Key Takeaways

Convertible notes in Singapore are debt instruments that convert into equity at a priced round, and every stage from issuance to allotment requires specific corporate, regulatory, and tax steps to be executed correctly.

Point	Details
Section 161 authority is mandatory	Shareholder authority to allot conversion shares must be current at the time of allotment, not just at signing.
ACRA filing deadline is 14 days	The Return of Allotment must be filed within 14 days of the allotment date; missing this is a statutory breach.
SFA exemption must be confirmed upfront	Accredited investor or private-placement exemption documentation must be obtained before the note is issued.
Cap is the dominant economic term	Model the cap against down-round, up-round, and acquisition scenarios before agreeing; it typically drives more dilution than the discount.

How convertible notes work in Singapore: mechanics, math, and a worked example

A convertible note starts as debt. The company borrows a principal amount, accrues interest at an agreed rate, and the outstanding balance (principal plus accrued interest) converts into shares when a defined trigger occurs. The conversion price determines how many shares the noteholder receives.

Core formula:

Shares issued = (Principal + Accrued Interest) ÷ Conversion Price

The conversion price is typically the lower of two values: the capped price (pre-money valuation cap ÷ fully diluted shares) and the discounted price (price per share in the qualifying round × (1 minus discount rate)).

Conversion triggers include:

A qualified financing round (usually defined by a minimum raise threshold)
A liquidity event or acquisition
Maturity date, if the note has not already converted
Change of control, which may trigger automatic conversion or redemption at the investor’s election

Worked example — S$500,000 note:

After 12 months, accrued interest totals S$40,000, bringing the outstanding balance to S$540,000.

At a qualifying round priced at a per-share price on a certain pre-money valuation with a specific number of fully diluted shares:

Discounted price is calculated by applying the discount to the round price
Capped price is calculated as the valuation cap divided by fully diluted shares
Applicable price is the lower of these two
Shares issued equals the outstanding balance divided by the applicable price

Without the cap, the investor would have received fewer shares at the discounted price. The cap increases shares issued, a notable effect often underestimated when modeling dilution.

Fractional shares are typically rounded down to the nearest whole share, with the residual amount paid in cash or carried forward. Conversion should occur within a contractually specified window — publicly filed agreements commonly set this at 15 business days from the conversion trigger date.

Pro Tip: *Always run the cap-table model with the cap binding and without it.

Negotiation checklist: clauses founders and investors must agree on

Every convertible loan agreement in Singapore contains a core set of negotiable terms. The ranges below are illustrative market references, not prescriptive standards.

Principal and subscription mechanics

Confirm the subscription amount, payment date, and whether tranches are permitted. Multi-tranche notes require intercreditor alignment from the outset.

Interest rate and accrual

Seed-era notes typically carry interest per annum, often simple interest. Compounding interest favors investors; founders should push for simple accrual. Higher rates may attract scrutiny under the Moneylenders Act if the lender is not an institutional investor.

Maturity date

Maturities often range around one to two years. Founders prefer longer maturities; investors want a fallback date that creates negotiating leverage. Include an extension option (mutual or unilateral) to avoid forced redemption at an inconvenient time.

Discount rate

Market range: 10–30%. A 20% discount is common at seed stage. Discounts above 25% can signal investor skepticism about the company’s ability to raise at a higher valuation.

Valuation cap

The single most negotiated term. A low cap rewards early investors but can create a cliff in dilution that deters Series A investors. Model the cap against three exit scenarios before agreeing.

Most-favored-nation (MFN) clause

Investors often insist on MFN rights so that if a later note is issued on better terms, they receive the same. Founders should limit MFN to economic terms only, not governance rights.

Conversion mechanics and qualified financing threshold

Define “qualified financing” precisely: minimum gross proceeds, share class, and whether convertible instruments count toward the threshold. Ambiguity here is a common source of disputes.

Change-of-control and liquidity event treatment

Specify whether the note converts automatically or the investor may elect redemption at a premium (e.g., 1.0–1.5× principal) on a change of control. Automatic conversion is cleaner for founders; investors prefer optionality.

Repayment and redemption rights

At maturity without conversion, the investor’s right to demand repayment must be explicit. Some notes include a conversion-at-maturity fallback at a pre-agreed price.

Events of default

Standard triggers: failure to repay at maturity, insolvency, material breach of representations. Avoid broad cross-default clauses that give investors acceleration rights on minor breaches.

Information rights

Quarterly management accounts are standard. Annual audited financials are common for notes above S$500,000.

Transfer and assignment

Restrict transfer to affiliates or approved transferees to prevent the note ending up with a hostile party.

Pro Tip: Negotiate the conversion mechanics and qualified financing definition before agreeing on the cap. A high cap with a narrow qualified-financing definition can leave the note unconverted indefinitely.

Singapore legal and regulatory requirements for issuing a convertible note

A convertible note is a debt contract until conversion. At that point, it becomes a securities transaction subject to the Companies Act and, depending on the offer structure, the Securities and Futures Act (SFA).

Companies Act: section 161 allotment authority

Under section 161 of the Companies Act, directors need shareholder authority to allot new shares. This authority is typically granted by an ordinary resolution at the annual general meeting (AGM) or by a special resolution. The authority must be current at the time of allotment, not just at the time the note is signed. A common operational failure is executing a conversion after the section 161 authority has lapsed.

When conversion occurs, the company must file a Return of Allotment with ACRA within 14 days of the allotment date and update the register of members to reflect the new shareholder.

SFA and MAS: prospectus exemptions

The MAS regulates offers of securities under the SFA. An offer of convertible notes to the public generally requires a prospectus. However, most startup convertible-note rounds qualify for one of the following exemptions:

Private placement exemption: offers to no more than 50 persons in any 12-month period
Small personal offers exemption: aggregate consideration not exceeding S$5 million in any 12-month period
Accredited investor exemption: offers made solely to accredited investors (individuals with net personal assets exceeding S$2 million, or net financial assets exceeding S$1 million, or annual income of at least S$300,000; or institutional investors)

Reliance on an exemption must be documented. Obtain a signed investor declaration confirming accredited investor status before closing.

Key regulatory principle: The SFA exemption must be confirmed before the note is issued, not retrospectively. Issuing a convertible note without confirming the applicable exemption exposes the company and its directors to civil and criminal liability under the SFA.

Procedural checklist

Step	Action Required	Timing
Board resolution	Approve issuance of note, terms, and reliance on SFA exemption	Before signing
Shareholder resolution	Grant or confirm section 161 allotment authority	Before or at signing
Investor declaration	Signed accredited investor or exemption confirmation	Before closing
Note execution	Sign convertible loan agreement and issue note certificate	At closing
Conversion notice	Investor or company serves notice per agreement terms	At trigger event
Return of Allotment	File with ACRA within 14 days of allotment	Post-conversion
Register update	Update register of members and cap table	Post-conversion

IRAS, stamp duty, and accounting treatment for convertible debt

Stamp duty

IRAS guidance on stamp duty for shares confirms that stamp duty applies to instruments for the transfer or acquisition of shares. The key question for convertible notes is whether the conversion constitutes a “transfer” or an “acquisition” that triggers stamp duty.

Where a convertible note converts into newly allotted shares (rather than a transfer of existing shares), stamp duty is generally not triggered on the allotment itself. Founders and investors should confirm the conversion mechanics with a tax advisor before execution to avoid unexpected stamp duty costs.

Accounting treatment

The accounting treatment of a convertible note depends on its terms:

Debt classification: If the note has a fixed maturity and mandatory repayment terms, it is classified as a financial liability under FRS 109 (Singapore’s equivalent of IFRS 9). Interest accrues as a finance cost on the income statement.
Equity component: If the note contains an equity conversion feature at the holder’s option, it may require bifurcation into a debt component and an equity component under FRS 32. The equity component is recorded in equity at inception.
Conversion event: On conversion, the carrying amount of the debt (and any accrued interest) is reclassified to share capital and share premium. No gain or loss is recognized on conversion under the debt-to-equity reclassification.

Practical mitigation steps

Obtain a written tax opinion or IRAS advance ruling on stamp duty treatment before conversion, particularly for notes above S$1 million.
Document the fair market value of shares at the conversion date. IRAS may reference this value in any subsequent review.
Coordinate with your auditor on the FRS 109/FRS 32 classification at the time the note is signed, not at conversion. Reclassification after the fact creates audit complications.
Use the annual tax filing process to reconcile the accounting and tax treatment of interest accrued during the note’s life.

Key accounting checkpoint: Interest accrued on a convertible note is a deductible expense for corporate tax purposes under Singapore’s Income Tax Act, provided the note is a genuine arm’s-length debt instrument. Retain documentation of the commercial rationale for the interest rate agreed.

Roadmap from term sheet to conversion: timeline and document checklist

The typical convertible-note round in Singapore moves through six stages. Each stage has a defined document set and a practical time estimate.

Stage 1: Term sheet (1–3 days)

Document: Non-binding term sheet setting out principal, interest, maturity, discount, cap, and key conditions.
Action: Both parties sign; no binding obligations other than exclusivity (if included).

Stage 2: Due diligence and legal drafting (1–3 weeks)

Documents: Convertible loan agreement (or convertible note instrument), subscription letter, investor declaration.
Action: Legal counsel drafts and negotiates the agreement. Confirm SFA exemption category and obtain investor declaration. For newly incorporated entities, confirm incorporation timeline and company bank account status.

Stage 3: Board and shareholder approvals (3–7 days)

Documents: Board minutes approving the note and SFA exemption reliance; shareholder resolution granting or confirming section 161 authority.
Action: Circulate resolutions for signature. For companies with a single director-shareholder, a written resolution suffices.

Stage 4: Execution and closing (1–2 days)

Documents: Executed convertible loan agreement, note certificate, subscription letter.
Action: Investor transfers subscription proceeds to the company’s designated bank account. Company issues the note certificate. Retain evidence of fund receipt.

Stage 5: Conversion event (1–5 days after trigger)

Documents: Conversion notice (served by investor or company per agreement terms), board minutes approving allotment, updated cap table.
Action: Confirm the conversion price calculation. Prepare allotment documentation.

Stage 6: ACRA filing and register update (within 14 days of allotment)

Documents: Return of Allotment filed via BizFile+, updated register of members.
Action: File the Return of Allotment with ACRA. Update the share register and issue new share certificates if required.

Practical guidance for fundraising in Singapore: Build the ACRA filing deadline into the closing checklist from day one. Missing the 14-day window is a statutory breach, even when the conversion itself is commercially straightforward.

Where to find Singapore-ready templates and annotated clauses

Model documents worth reviewing

SVCA VIMA 2.0 Model Convertible Note Purchase Agreement is the most widely used Singapore-oriented template among practitioners. It includes local SFA-exemption language, section 161 references, and conversion mechanics drafted for Singapore law. Use it as the base document, but expect to customize the qualified-financing definition, cap, and discount for each deal.

CooleyGo Singapore Convertible Promissory Note and Term Sheet provides an English-language model with practical drafting notes on conversion events and investor protections. Useful for cross-border deals where investors are familiar with US-style note mechanics but the company is Singapore-incorporated.

Dentons Rodyk publicly filed convertible loan agreement (CytomEd Therapeutics / MDR Limited) shows real-world clause patterns: a percentage discount, conversion within 15 business days, and elective redemption rights. The conversion-timing clause is particularly instructive for drafting a tight notice mechanism.

The Captain Legal Singapore template documents the Companies Act and SFA interaction points and is a useful reference for the statutory checklist.

Three copy-ready micro-clauses

Clause	Sample Language	Local Annotation
Conversion notice	“The Investor shall deliver a Conversion Notice to the Company within [5] Business Days of the occurrence of a Qualified Financing, specifying the Conversion Price and the number of Conversion Shares to be allotted.”	Insert the agreed notice period; 5–15 business days is market standard. Cross-reference the section 161 authority resolution.
Discount formula	“The Conversion Price shall be the lower of: (a) the price per share paid by investors in the Qualified Financing multiplied by (1 minus the Discount Rate); and (b) the Valuation Cap divided by the Fully Diluted Share Capital immediately prior to the Qualified Financing.”	Define “Fully Diluted Share Capital” to include all options, warrants, and convertible instruments to avoid disputes at conversion.
Maturity extension	“The Maturity Date may be extended by [12] months by written agreement of the Company and the Majority Noteholders, provided that no Event of Default has occurred and is continuing.”	Require majority noteholder consent (not unanimity) to avoid a single holdout blocking a commercially sensible extension.

Red flags in template reuse:

Using a single-form template across multiple tranches without updating the cap and discount for each tranche creates inconsistent economic terms that are difficult to reconcile at conversion.
Missing intercreditor alignment across tranches can give early noteholders priority rights that later investors did not anticipate.
Reusing a template without inserting current SFA-exemption language exposes the company to a prospectus requirement it did not intend to trigger.

Seek bespoke drafting when the deal involves multiple tranches, offshore investors, or a cap table with existing convertible instruments.

SAFE vs convertible note in Singapore: which instrument fits your deal?

The core legal difference is straightforward. A convertible note is a debt instrument: it carries interest, has a maturity date, and creates a repayment obligation if conversion does not occur. A SAFE (Simple Agreement for Future Equity) or its Singapore equivalent, the CARE (Convertible Agreement Regarding Equity), is a contract for future equity with no maturity date and no interest accrual.

The SVCA CARE model (updated 2025) is the Singapore-specific instrument designed for this purpose. It functions as the local-law equivalent of the Y Combinator SAFE and is drafted to address Singapore Companies Act and SFA requirements.

When a convertible note is the better choice:

The investor wants a fallback repayment right if the company does not raise a priced round within the maturity window.
The deal involves a larger principal amount where the investor requires the contractual protections of a debt instrument.
The investor is a financial institution or fund with internal policies requiring debt classification.

When a CARE or SAFE is the better choice:

The founder wants to avoid creating a debt obligation on the balance sheet.
Speed is a priority: a CARE has fewer negotiable terms and closes faster.
Both parties are comfortable with no maturity date and no interest accrual.

Decision checklist:

Does the investor require a repayment fallback? Convertible note.
Is the principal above S$500,000 and the investor a fund? Convertible note.
Is this a small friends-and-family round with a tight timeline? CARE.
Does the founder want to avoid balance-sheet debt? CARE.

The CARE is not always the simpler instrument from a legal perspective. Its conversion mechanics still require section 161 authority and an ACRA Return of Allotment at conversion, and SFA exemption analysis applies equally.

Common pitfalls, red flags, and negotiation tactics to avoid deal failure

Singapore practitioners consistently identify the same failure modes across convertible-note transactions. Addressing them at drafting stage costs far less than resolving them in dispute.

Red flags to identify before signing:

Inconsistent caps across tranches. If earlier tranches carry a lower cap than later ones, early investors convert at a lower price and create a dilution cliff that deters Series A investors. Align caps across tranches or document the rationale for differences.
Missing intercreditor arrangements. Multiple noteholders with different maturity dates and conversion rights, and no intercreditor deed, creates a race to convert or redeem at the trigger event.
Broad investor consent rights. Clauses requiring individual noteholder consent (rather than majority consent) for material company decisions give a single investor veto power over fundraising, M&A, and operational decisions.
Ambiguous conversion mechanics. Undefined terms such as “pre-money valuation” or “fully diluted shares” in the conversion formula produce different outcomes depending on which interpretation is applied. Define every term in the definitions section.
Missing section 161 authority. Allotting conversion shares without current shareholder authority renders the allotment void under the Companies Act. This is the single most common operational failure in convertible-note conversions.

Negotiation tactics:

Model cap-table outcomes across three scenarios before agreeing on the cap: a down-round (next round priced below the cap), an up-round (next round priced above the cap), and an acquisition at a fixed enterprise value. Each scenario produces a different conversion outcome, and founders frequently agree to caps without running the down-round case.
Insist on clause alignment across tranches. If a second tranche is issued, the conversion mechanics, cap, and discount should be documented in a separate note or an amendment to the original agreement, not assumed to carry over.
When multiple investors participate, require a majority-noteholder consent mechanism for all material decisions. This prevents a single holdout from blocking a commercially necessary extension or conversion.
For corporate advisory on cap-table modeling and term negotiation, engage a specialist before the term sheet is signed, not after.

Pro Tip: *Simulate the acquisition scenario at 1× the valuation cap.

A practitioner’s perspective on convertible-note rounds in Singapore

The most consistent observation from working with Singapore startups on convertible-note transactions is that the legal complexity surfaces at conversion, not at signing. Founders treat the note as a simple loan and defer the hard questions — section 161 authority, SFA exemption documentation, cap-table modeling — until a priced round is imminent. By that point, fixing a defective allotment or a lapsed shareholder authority is expensive and time-consuming.

One pattern that recurs: a company issues a convertible note to three investors across two tranches over 18 months. The first tranche is documented carefully. The second tranche reuses the first tranche’s agreement with minimal changes, including the same cap, even though the company’s valuation has moved materially. At conversion, the first-tranche investors convert at a significantly lower price than the second-tranche investors, creating a cap table that the Series A lead finds difficult to accept. The fix requires renegotiating with all noteholders simultaneously, which delays the round by six to eight weeks.

The corrective steps are straightforward when applied from the outset: document each tranche separately, align caps to the company’s current stage, obtain fresh section 161 authority before each allotment, and file the Return of Allotment with ACRA within the statutory 14-day window. Triangle Legal’s guidance reinforces this point: Singapore courts enforce the written terms strictly, and contractual drafting determines outcomes at conversion.
