A bonus issue is the free distribution of additional shares to existing shareholders in proportion to their current holdings, funded by capitalising a company’s reserves rather than raising new cash, typically used by SGX-listed companies to improve share price affordability and trading liquidity.

Key Takeaways
- A bonus issue does not raise any new capital for the company — it simply capitalises existing reserves into additional shares, unlike a rights issue which raises fresh cash from shareholders.
- Common bonus issue ratios on SGX include 1-for-2, 1-for-5 or 1-for-10, meaning shareholders receive that many extra shares for every share they already hold.
- Because the company’s total value is unchanged, the share price adjusts proportionally downward on the ex-date to reflect the larger number of shares in issue.
- A bonus issue does not dilute an existing shareholder’s percentage ownership, since every shareholder receives the same proportional number of new shares.
- Bonus shares are credited directly into shareholders’ CDP or custodian accounts on the entitlement date, with no action or payment required from the shareholder.
What Is a Bonus Issue?
A bonus issue, sometimes called a scrip bonus or capitalisation issue, is when a company converts part of its retained earnings or other reserves into new shares, which are then distributed free to existing shareholders in proportion to their current holdings. No cash changes hands between the company and its shareholders — the company’s balance sheet simply reclassifies reserves into paid-up share capital, while the total number of shares in issue increases.
Companies typically announce a bonus issue when their share price has climbed to a level perceived as too high for retail investors to trade comfortably in round lots, or when management wants to signal confidence in the business without the dilution that comes from issuing new shares for cash.
How Does a Bonus Issue Work on SGX?
On the Singapore Exchange, a bonus issue follows a defined timeline announced via SGXNet: the company first announces the bonus ratio and indicative timetable, followed by a book closure date (also called the record date), and an ex-date — the first day the shares trade without the right to the bonus shares. Investors who hold the shares before the ex-date are entitled to the bonus; those who buy on or after the ex-date are not. The actual bonus shares are credited to shareholders’ Central Depository (CDP) accounts or custodian/brokerage accounts automatically on the entitlement date, usually within a few weeks of the ex-date, with no paperwork required from shareholders.
Singapore has seen companies across sectors use bonus issues, from established names historically distributing bonus shares to improve liquidity, to smaller-cap companies on Catalist doing so to widen their shareholder base and increase board lot affordability ahead of inclusion in certain indices or to meet minimum free float expectations.
Investors should also note that a bonus issue can sometimes be announced alongside a change to a company’s board lot size or ahead of a planned index review, since a lower, more liquid share price following the bonus can help a stock meet minimum trading volume or free float criteria used by index providers, which in turn can affect passive fund flows into the stock over time.
Bonus Issue Example
Suppose an investor holds 10,000 shares of XYZ Ltd, trading at S$2.00 per share just before the ex-date, for a total position value of S$20,000. XYZ announces a 1-for-5 bonus issue, meaning for every 5 existing shares held, the shareholder receives 1 new bonus share.
The investor’s 10,000 shares entitle them to 2,000 additional bonus shares, bringing their total holding to 12,000 shares. Because the company’s total market capitalisation has not changed, the share price adjusts downward on the ex-date to approximately S$1.67 (S$2.00 × 10,000 ÷ 12,000), so the investor’s total position value remains approximately S$20,000 — unchanged in value, but now spread across more, lower-priced shares.
Advantages of a Bonus Issue
- Improves affordability and liquidity. A lower per-share price after the bonus issue can make the stock more accessible to retail investors trading in standard board lots, potentially increasing trading volume.
- No dilution of ownership percentage. Every shareholder receives bonus shares in the same proportion, so relative ownership stakes in the company are unchanged.
- Signals management confidence. Issuing a bonus, rather than conserving reserves, can be read by the market as a sign that management is comfortable with the company’s underlying financial strength.
- No tax event for shareholders. Bonus shares received are generally not treated as taxable income in Singapore, since no cash dividend has actually been paid.
Risks and Limitations
- No change in underlying company value. A bonus issue does not create any new wealth for shareholders — it simply redistributes the same total value across more shares, so investors should not mistake it for a genuine return.
- Dividend per share may need repricing. If a company previously paid a fixed cents-per-share dividend, it may need to adjust the per-share dividend downward after a bonus issue to maintain the same total payout, which can look like a dividend cut if investors don’t account for the larger share base.
- Can signal an illiquid, overpriced stock rather than strength. In some cases, a bonus issue simply reflects that a stock’s price had become so high that ordinary investors were being priced out, rather than being a pure confidence signal.
- Administrative noise around the ex-date. Investors need to track entitlement and ex-dates carefully, especially when trading around the corporate action, to avoid confusion over which holdings qualify.
Common Mistakes Singapore Investors Make
A common error is mistaking the increase in share count after a bonus issue for genuine portfolio growth. Because the total value of the position is mathematically unchanged (aside from any sentiment-driven re-rating), investors who see ‘12,000 shares’ where they used to have ‘10,000 shares’ sometimes feel wealthier than they actually are, overlooking that the price per share has adjusted down to compensate.
Another mistake is failing to adjust historical dividend-per-share figures when comparing a stock’s yield before and after a bonus issue. If a company previously paid S$0.10 per share in dividends and later issues a 1-for-5 bonus without adjusting the dividend rate, the total cash paid to a shareholder actually increases proportionally — but comparing the unadjusted S$0.10 figure across periods without accounting for the larger share base produces a misleading year-on-year yield comparison.
Bonus Issue vs Stock Split vs Rights Issue
These three SGX corporate actions are often confused because all three change the number of shares an investor holds, but the mechanics and purpose differ.
| Feature | Bonus Issue | Stock Split | Rights Issue |
|---|---|---|---|
| Cash raised by company | None | None | Yes, from shareholders who subscribe |
| Funding source | Capitalises reserves into share capital | No accounting entry — shares simply subdivided | New cash subscription from shareholders |
| Shareholder cost | Free | Free | Shareholders pay a subscription price |
| Effect on ownership % | Unchanged for all shareholders | Unchanged for all shareholders | Can dilute shareholders who don’t subscribe |
| Typical purpose | Improve liquidity, signal confidence | Lower price per share for affordability | Raise fresh capital for the business |

The Bottom Line
A bonus issue is a cosmetic but useful corporate action — it makes shares more affordable and liquid without raising fresh capital or diluting ownership percentages. Singapore investors should treat the extra shares as a repricing of their existing stake rather than a windfall, and watch for any corresponding adjustment to per-share dividends going forward.
Frequently Asked Questions
Do I need to pay anything to receive bonus shares in Singapore?
No, bonus shares are distributed free to existing shareholders in proportion to their holdings and are automatically credited to CDP or custodian accounts with no payment or action required.
Does a bonus issue dilute my shareholding?
No, because every shareholder receives bonus shares in the same proportion, your percentage ownership of the company stays exactly the same before and after the bonus issue.
Why does the share price drop after a bonus issue?
The share price adjusts downward on the ex-date because the same total company value is now spread across a larger number of shares, so the price per share falls proportionally even though the investor’s total position value is unchanged.
Is a bonus issue the same as a stock split?
They achieve a similar practical effect of more, lower-priced shares, but a bonus issue involves an accounting entry capitalising reserves into share capital, while a stock split simply subdivides existing shares with no such accounting reclassification.
Are bonus shares taxed in Singapore?
Generally no, because a bonus issue is not treated as a cash dividend payment; shareholders do not receive taxable income simply from being allotted bonus shares.
Does a bonus issue increase the total dividends I receive?
Only if the company maintains or increases its per-share dividend rate after the bonus issue — since you now hold more shares, an unchanged per-share dividend rate would increase your total cash dividend, though companies sometimes adjust the per-share rate downward to keep total payout roughly stable.
Can a company issue bonus shares and pay a cash dividend at the same time?
Yes, a bonus issue and a regular cash dividend are independent corporate actions, and companies sometimes announce both together, particularly when a bonus issue is intended mainly to improve share price affordability rather than signal any change in dividend policy.
