Bonus Issue
阅读 978 · 更新时间 December 12, 2025
A bonus issue, also known as a scrip issue or a capitalization issue, is an offer of free additional shares to existing shareholders. For example, a company may give one bonus share for every five shares held. Companies issue bonus shares to attract further investment and reward shareholders.
Core Description
- A Bonus Issue increases a company’s outstanding shares by issuing additional shares to existing shareholders, capitalizing reserves but not altering overall ownership or intrinsic value.
- The process is intended to signal management confidence, enhance market liquidity, and bring the share price to a more accessible range, although its mechanics and end results are distinctly different from those of stock splits or cash dividends.
- Investors should focus on understanding the rationale, key dates, and the implications for per-share metrics, recognizing that a Bonus Issue is value-neutral upon issuance but may influence market perception and investment strategy.
Definition and Background
A Bonus Issue—also referred to as a capitalization issue or scrip issue—is a corporate action where a company distributes additional shares to its existing shareholders, without any payment required, by converting retained earnings or other reserves into share capital. Common bonus issue ratios include 1-for-5 or 1-for-1, meaning for every five or every one share held, one new share is granted, respectively.
Historical Context
Bonus Issues originated in the late 19th and early 20th centuries, when companies aimed to align legal capital with their expanding operations without using cash, especially under par-value share regimes. In markets such as the United Kingdom and former dominions, scrip issues were utilized to boost liquidity and widen share ownership. Over time, common law markets such as Australia, Canada, and India established rules for Bonus Issues, linking them to accumulated reserves and requiring company approval. According to IFRS, a Bonus Issue represents a simple transfer within equity, requiring per-share metrics to be restated for all reporting periods.
Regulatory Evolution
Investor protection is a key focus, with regulators such as the SEC (United States), FCA (United Kingdom), and SEBI (India) requiring transparent disclosure of all Bonus Issue terms, including ratio, record date, board approval, and ex-date, to ensure fair treatment of shareholders.
Calculation Methods and Applications
How is a Bonus Issue Calculated?
The common ratio, expressed as M-for-N, means investors receive M new shares for every N shares already held. Formulas used include:
New Shares per Shareholder = Existing Shares × (M/N)
Total Post-Issue Shares = Existing Shares × (1 + M/N)
Example Calculation (Hypothetical)
A shareholder holds 1,000 shares. The company executes a 1-for-5 Bonus Issue.
- New shares received: 1,000 × (1/5) = 200
- Total shares after bonus: 1,000 + 200 = 1,200
Theoretical Ex-Bonus Price (TEBP)
To keep the company’s total market value unchanged, the share price after the bonus is expected to adjust proportionally:
TEBP = Old Price × (N/(N+M))
For example, if the pre-bonus price is USD 60 and a 1-for-5 bonus is declared:
TEBP = USD 60 × (5/6) = USD 50
Accounting Treatment
The typical accounting entry is:
- Debit: Retained Earnings or Share Premium (for par value of new shares)
- Credit: Share Capital
No cash is exchanged; only the structure of shareholders’ equity is altered.
Adjustments in Per-Share Metrics
After a Bonus Issue, Earnings Per Share (EPS), Book Value Per Share, and similar metrics are divided by the bonus factor (1 + M/N). This ensures comparability across reporting periods.
Market Cap and Ownership
Market capitalization usually remains stable:
- Market Cap (Post-bonus) = Adjusted Price × Total Shares (post-issue), which is approximately equal to pre-bonus market capitalization.
- Each shareholder’s ownership percentage remains the same, as both individual and total shareholdings rise proportionally.
Treatment of Fractions
If a Bonus Issue leads to fractional shares, most markets round down to the nearest whole share and compensate for any remaining entitlement by cash payment, usually at the ex-bonus price.
Comparison, Advantages, and Common Misconceptions
Key Comparisons
Bonus Issue vs Stock Split
| Aspect | Bonus Issue | Stock Split |
|---|---|---|
| Reserves Used | Yes (capitalizes reserves) | No (just divides shares) |
| Share Capital | Increases | Unchanged |
| Ratio Example | 1-for-5, 2-for-1 | 2-for-1, 3-for-1, etc. |
| Per-Share Price | Falls proportionally | Falls proportionally |
| Ownership | Unchanged | Unchanged |
Bonus Issue vs Cash Dividend
A Bonus Issue provides additional shares without using company cash; a cash dividend distributes direct payments to shareholders and reduces the company's retained earnings and cash reserves.
Bonus Issue vs Rights Issue
A Bonus Issue is free and does not raise new cash. A Rights Issue offers existing shareholders the ability to purchase additional shares, usually at a discount, thereby raising funds for the company.
Bonus Issue vs DRIP
A Dividend Reinvestment Plan (DRIP) automatically reinvests cash dividends into new shares (sometimes fractions). A Bonus Issue is a one-off event in which the entire shareholder base receives new shares from reserves as a mandatory action.
Advantages
- Increases the number of tradable shares, potentially improving market liquidity.
- Signals management's confidence in the financial health of the business.
- May result in the share price moving into a range more accessible for a broader pool of investors.
- Enables companies to reward shareholders without reducing cash reserves.
Disadvantages
- No immediate increase in the total value of a shareholder's investment; the value typically remains unchanged after the adjustment.
- Dilutes per-share statistics such as EPS and book value per share, which may be misinterpreted as actual business dilution.
- Results in increased administrative and settlement activities.
- May introduce short-term share price volatility.
Common Misconceptions
"Bonus shares make investors richer"
The allocation of bonus shares does not directly increase shareholder wealth. Although shareholders own more shares, the market-adjusted price means that the total value typically stays the same unless supported by improved company performance.
"Bonus Issues are the same as stock splits"
While both actions increase the number of shares and decrease per-share price, only a Bonus Issue capitalizes reserves and modifies the composition of shareholders’ equity.
"Receiving bonus shares is a form of income"
Bonus shares are generally not considered income and do not usually generate tax liability upon receipt. Taxation commonly occurs when the shares are sold.
Practical Guide
Understanding & Evaluating a Bonus Issue
1. Identify Bonus Terms
Review company announcements and circulars to determine the bonus ratio, eligibility requirements, key dates, and the stated rationale. Confirm how and when the entitlement is calculated and credited.
2. Track Key Dates
Holding shares before the ex-date is necessary to receive bonus shares. In T+2 markets, the ex-date is typically one business day before the record date. Missing this window means missing the bonus entitlement.
3. Assess Motives and Implications
Carefully consider the company's reasons for issuing a bonus. Motivations can include improving liquidity, signaling financial health, or addressing regulatory requirements. Review the adequacy of company reserves and whether the action allows flexibility for other capital uses.
4. Recalculate Portfolio Metrics
After receiving bonus shares, update your position, revise the average cost per share, and rebalance portfolio risks if necessary. Adjust any relevant per-share metrics and entry prices.
5. Factor in Tax and Accounting
In many developed markets, no tax is due on receipt, but the cost basis per share will usually decrease. This affects capital gains or losses upon sale, so accurate record-keeping is essential for future compliance.
6. Adjust Trading Behavior
Nominal share prices may fall post-bonus, which can increase trading volume but may also cause short-term volatility. Use appropriate trade methods and be mindful of changes in lot sizes or technical thresholds.
Case Study (Illustrative Example - Not Investment Advice)
In 2018, Infosys, a large IT company, declared a 1:1 Bonus Issue. Each shareholder received one new share for every share held, doubling share count immediately. The share price adjusted to half on the ex-date, with market capitalization unchanged. The management cited ample reserves and a positive outlook. While there was an immediate increase in trading activity and liquidity, longer-term share performance followed business fundamentals, not the share count.
Common Pitfalls to Avoid
- Confusing bonus shares as additional investment value or income.
- Overlooking ex-date and record date, resulting in entitlement loss.
- Failing to restate portfolio and per-share metrics after receiving bonus shares.
- Mistaking bonus issues for rights issues or splits.

FAQs
What is a bonus issue?
A bonus issue is the allocation of free additional shares to existing shareholders at a fixed ratio by capitalizing company reserves, rather than by distributing cash. It does not affect the shareholder’s ownership percentage or the company’s overall equity value directly.
How does a bonus issue affect share price and market capitalization?
The share price generally reduces in proportion to the bonus ratio, ensuring that the company’s total market capitalization remains the same, except in the case of other market movements.
Why do companies issue bonus shares?
Companies may issue bonus shares to express management confidence, increase share liquidity, bring the share price into an accessible trading range, and align share capital with company reserves, without reducing cash resources.
Who is eligible to receive bonus shares?
Shareholders who hold the shares as of the close of business on the record date set by the company are eligible. Purchasers acquiring shares after the ex-date are typically not entitled to the bonus issue.
What happens to fractional entitlements?
If the bonus ratio leads to a fractional share, most companies pay the cash value of the fraction or group fractions together and distribute the sales proceeds pro rata.
How are bonus shares taxed?
Generally, bonus shares are not taxed when received. Taxation of gains or losses occurs upon the sale of these shares, as the cost base per share will change retrospectively. It is important to verify local tax guidelines.
How is a bonus issue different from a stock split?
A bonus issue increases the number of shares by drawing upon reserves, altering the share capital structure. Alternatively, a stock split multiplies existing shares with no reserve adjustment or impact on share capital.
What is the effect of a bonus issue on EPS and dividends?
Following a bonus issue, sums like EPS and dividends per share decrease in proportion to the bonus ratio, although the company’s total earnings and total dividend payments remain unchanged unless payout policy is revised.
Conclusion
A Bonus Issue represents a meaningful corporate action that can sometimes be misunderstood by investors. By converting reserves into equity capital, the company increases outstanding shares and adjusts per-share metrics, which can potentially improve market liquidity. However, this does not automatically enhance shareholder value at the time of the issuance. It is essential for investors to clearly understand the mechanics, the regulatory framework, and the implications for their portfolios. Reviewing official announcements, monitoring vital dates, and leveraging reputable educational resources will help investors make informed decisions and adapt their investment strategies when companies declare bonus issues.
