Editor’s note: This is an educational explainer about how bonus issues generally work in equity markets. It is general information, not investment advice, and does not describe any specific current event, company, or security.
A shareholder who owned 100 shares on Monday can wake up on Tuesday owning 150, without buying a single additional share or spending a cent. The company has not sold new stock to raise cash, and no dividend cheque has been issued. So where did the extra 50 shares come from, and why doesn’t the shareholder feel 50 percent richer? The answer lies in the mechanics of a bonus issue, sometimes called a scrip issue or capitalisation issue, and understanding it clarifies a distinction that trips up many newer investors: the difference between receiving more shares and receiving more value.
How a bonus issue is created
A bonus issue is, at its core, an accounting reclassification. A company’s balance sheet holds shareholders’ equity in several buckets: share capital, and various reserves built up from retained profits or share premium over the years. When a board declares a bonus issue, say one new share for every two already held, it simply moves money out of the reserves bucket and into the share capital bucket, then issues new share certificates to reflect that shift. No cash leaves the company. No cash enters it either. Total shareholders’ equity on the balance sheet is exactly the same the day after the bonus issue as it was the day before.
What changes is the number of shares outstanding, and correspondingly, each investor’s shareholding rises in the same proportion as everyone else’s. A holder of 200 shares in a 1-for-2 bonus issue ends up with 300 shares. So does every other shareholder, in the same ratio, so nobody’s percentage ownership of the company changes at all. This is precisely why exchanges adjust the share price downward on the ex-bonus date, in this example by a factor that keeps the arithmetic consistent, roughly multiplying the prior price by two-thirds. A pizza cut into more slices is not a bigger pizza, and a company divided into more shares is not a more valuable company. Market capitalisation, in theory, should be unchanged immediately after the adjustment, before ordinary trading activity pushes the price around for other reasons.
Why it differs economically from a dividend
A cash dividend is a genuine transfer of value out of the company and into shareholders’ pockets. When a company pays a dividend, cash actually leaves its bank account, its assets shrink accordingly, and shareholders receive money they can spend, reinvest, or hold as they choose. The share price is adjusted downward on the ex-dividend date too, but for a different reason: the company is now worth less because it literally has less cash, having given some away.
A bonus issue involves no such outflow. The company’s assets, liabilities, and cash position are untouched. Nothing leaves the corporate entity and nothing arrives in a shareholder’s bank account; only paper (or, more accurately, electronic entries in a depository account) changes. This is why regulators and accountants treat the two events so differently: a dividend is income, often taxable as such in many jurisdictions, while a bonus issue is generally not treated as income at the point of issue, precisely because no value has actually transferred to the shareholder. It is worth noting that tax treatment varies by jurisdiction and investors should consult local rules or a qualified adviser rather than assume any particular outcome.
Why companies do it anyway
If a bonus issue doesn’t create wealth, why do boards bother? The most commonly cited reasons are practical rather than financial. Increasing the number of shares outstanding while lowering the price per share can improve liquidity, making the stock more affordable in round lots for a broader range of retail investors and potentially narrowing bid-ask spreads. It also signals confidence: a board typically only recommends capitalising reserves into share capital when it is comfortable that retained earnings are healthy and stable, since the retained-earnings cushion available for future dividends effectively shrinks as reserves convert into permanent share capital.
There is also a psychological dimension that market observers frequently discuss, sometimes called the “share price illusion.” Investors often respond favourably to owning more shares at a lower price per share, even though the underlying economics are unchanged, a behavioural quirk that exchanges and companies are well aware of. None of this means a bonus issue is meaningless. It can affect trading dynamics, index weightings, and per-share metrics like earnings per share, which mechanically falls after a bonus issue simply because the same profit is now divided among more shares. But as a matter of pure arithmetic, the moment the extra certificates land in an account, the shareholder’s stake in the company, and its total value, is precisely what it was the day before.
