A bonus share is an additional share given by a company to its existing eligible shareholders without requiring them to pay for those shares. Bonus shares are generally issued by capitalising eligible reserves, and the number of shares an investor holds increases according to the announced bonus ratio. However, receiving additional shares does not automatically increase the total value of the investment because the stock price is adjusted after the bonus issue.
What Is a Bonus Share?
A bonus share is a free additional share issued to existing shareholders in proportion to their existing holdings.
For example, suppose a company announces a 1:1 bonus issue. This means an eligible shareholder receives one additional share for every one share already held.
If an investor owns 100 shares before the bonus issue:
Before bonus: 100 shares
Bonus entitlement: 100 shares
After bonus: 200 shares
The company does not receive fresh cash from shareholders for these additional shares. Instead, eligible reserves are converted into share capital, subject to applicable regulations and corporate approvals.
Why Do Companies Issue Bonus Shares?
Companies may consider bonus issues for several reasons. One common reason is to restructure part of their accumulated reserves into paid-up share capital.
A company may also use a bonus issue when it wants to increase the number of shares available in the market. A larger number of outstanding shares can change the per-share price after adjustment and may make the stock more accessible to investors.
However, a bonus issue should not automatically be interpreted as a sign that the company will generate higher future returns. The underlying business fundamentals remain important.
How Does a Bonus Issue Work?
A bonus issue increases the number of shares held by eligible shareholders while proportionately adjusting the share price.
Consider a hypothetical company whose share trades at ₹600 and announces a 1:2 bonus issue, meaning one bonus share for every two shares held.
An investor holding 200 shares would receive 100 additional shares, taking the total holding to 300 shares.
The theoretical adjusted price would be approximately ₹400, assuming no other market movement:
200 × ₹600 = ₹1,20,000
After the bonus:
300 × ₹400 = ₹1,20,000
The example demonstrates why receiving additional shares does not automatically create additional wealth. Actual market prices can move differently because of buying and selling activity and other market factors.
What Is the Record Date for Bonus Shares?
The record date is an important date in a bonus issue because the company uses it to determine which shareholders are eligible to receive the bonus shares.
Investors should not rely solely on the record date when determining whether they qualify. The applicable ex-date, settlement cycle and exchange rules also matter.
For listed companies, the relevant dates are announced through official corporate disclosures. Investors should check the company’s exchange filing and the applicable stock exchange information for the precise eligibility requirements.
Who Is Eligible for Bonus Shares?
Generally, shareholders who are eligible according to the company’s announced terms and who hold the shares by the relevant eligibility date receive the bonus entitlement.
For example, if an investor holds 500 shares and the company announces a 1:1 bonus issue, the investor would generally receive 500 bonus shares if eligible.
The additional shares are subsequently credited to the investor’s demat account after the applicable corporate action and processing are completed.
What Is the Impact of Bonus Shares on Stock Price?
A bonus issue generally results in an adjustment to the market price because the total number of shares increases.
Suppose a company has 1 crore shares trading at ₹500 each. Its market capitalisation is ₹500 crore.
If it announces a 1:1 bonus issue, the number of shares can increase to 2 crore. Assuming the market capitalisation remains unchanged immediately after the adjustment, the theoretical price becomes approximately ₹250 per share.
This is why investors should not confuse a lower post-bonus share price with a sudden fall in the company’s overall market value.
Actual market prices can, of course, change after the bonus issue based on market sentiment, earnings, company developments and broader conditions.
Bonus Shares vs Stock Split
Bonus issues and stock splits can both increase the number of shares held by investors, but they are different corporate actions.
In a stock split, existing shares are divided into a larger number of shares and the face value is reduced proportionately.
In a bonus issue, additional shares are issued to eligible existing shareholders by capitalising eligible reserves. The face value generally remains unchanged unless another corporate action changes it.
Understanding this difference is useful when interpreting company announcements and changes in shareholdings.
Benefits and Limitations of Bonus Shares
A bonus issue can increase the number of shares held by existing shareholders without requiring an additional payment. It can also change the company’s share capital structure and potentially make the per-share market price lower after adjustment.
For investors, however, the important limitation is that additional shares do not automatically mean additional value. The investor’s overall holding value is adjusted through the change in the number of shares and market price.
There can also be tax and record-keeping considerations associated with bonus shares. Investors should maintain accurate transaction and corporate-action records and refer to applicable tax rules when calculating gains on a future sale.
What Should Investors Check After a Bonus Issue?
After a bonus issue, investors should verify:
- The bonus ratio announced by the company
- The record date and applicable ex-date
- The number of shares credited to the demat account
- The revised market price
- Updated cost and transaction records
- Any applicable tax implications when the shares are eventually sold
Investors should also remember that corporate actions can affect historical price charts and portfolio calculations. Using adjusted historical data can help avoid incorrect comparisons.
Conclusion
A bonus share is an additional share issued to eligible existing shareholders without requiring a separate payment. The number of shares increases according to the bonus ratio, while the market price is generally adjusted to reflect the increased number of shares.
For investors, the key point is that a bonus issue does not automatically increase the total economic value of an investment. The record date determines eligibility, while the bonus ratio determines how many additional shares an investor receives. Understanding these details can help shareholders interpret bonus announcements and track their portfolios more accurately.
Frequently Asked Questions
1. What is a bonus share in simple words?
A bonus share is an additional share issued by a company to eligible existing shareholders without requiring them to pay for it. The shares are generally issued by capitalising eligible reserves. The number of additional shares depends on the announced bonus ratio, such as 1:1 or 1:2.
2. What does a 1:1 bonus share mean?
A 1:1 bonus issue means an eligible shareholder receives one additional share for every one share already held. For example, an investor holding 100 shares would receive 100 bonus shares and hold 200 shares after the issue, subject to the applicable corporate action process.
3. What is the record date for bonus shares?
The record date is the date used by the company to determine shareholders eligible for the bonus issue. Investors should also consider the applicable ex-date and settlement rules. The company and stock exchanges announce the relevant dates, so investors should refer to official disclosures for the specific bonus issue.
4. Does a bonus share increase the investment value?
A bonus issue does not automatically increase the total value of an investor’s holding. Since the number of shares increases, the market price is generally adjusted proportionately. Future value depends on the actual market price, which can move based on company performance, investor sentiment and broader market conditions.
5. Are bonus shares really free?
Bonus shares do not require an additional payment from eligible shareholders at the time of issuance. However, they are not an automatic increase in economic value because the share price is adjusted after the bonus. The company is capitalising eligible reserves to increase its paid-up share capital.
6. How are bonus shares credited to a demat account?
Once the corporate action is processed, eligible bonus shares are generally credited electronically to the shareholder’s demat account. The timing can vary depending on the company’s process, depository and applicable regulatory or exchange procedures. Investors should check their demat holdings after the announced corporate-action process is completed.
7. What happens to the share price after a bonus issue?
The share price is generally adjusted downward in proportion to the bonus ratio because the number of outstanding shares increases. For example, in a 1:1 bonus issue, a theoretical ₹500 share could become approximately ₹250 after adjustment, assuming no other price movement.
8. What is the difference between bonus shares and stock splits?
A bonus issue provides additional shares to eligible existing shareholders by capitalising eligible reserves. A stock split divides existing shares into a larger number and proportionately reduces their face value. Both can increase the number of shares held, but they are different corporate actions with different accounting structures.
9. Can bonus shares be sold immediately?
Bonus shares generally need to be credited to the investor’s demat account and become available for trading according to the applicable listing and exchange process. The exact timeline can vary by corporate action. Investors should check the company’s exchange announcement for the date when the bonus shares are listed and available for trading.
10. Do bonus shares have tax implications in India?
Bonus shares can have tax implications when they are eventually sold. Under Indian tax rules, the cost basis and holding period for bonus shares are subject to specific provisions, and the applicable treatment can depend on factors such as the date of acquisition and the type of security. Investors should refer to current tax rules or seek professional advice for their circumstances.
