What Are Bonus Shares and How Do They Work?

How Do Bonus Shares Work?

Bonus shares work in a simple and structured way:

• A company announces a bonus issue ratio, such as 1:1, 2:1, or 3:2.
• The board of directors approves the bonus issue.
• The company declares the record date and ex-date.
• Eligible shareholders are identified based on the record date.
• Additional shares are credited directly to the shareholder's Demat account.
• The total number of shares held by investors increases.
• The share price is adjusted proportionately after the bonus issue.
• The overall value of the investment generally remains the same immediately after the bonus issue.
• Shareholders do not need to make any payment to receive bonus shares.
   

How To Calculate Bonus Share Percentage?

The bonus share percentage can be calculated using the following formula:

Bonus Share Percentage = (Bonus Shares Issued ÷ Existing Shares Held) × 100

Example
Suppose you hold 100 shares of a company and it announces a 1:2 bonus issue.

• Existing shares held = 100
• Bonus ratio = 1 bonus share for every 2 shares held
• Bonus shares received = 50

Bonus Share Percentage = (50 ÷ 100) × 100 = 50%
This means your shareholding increases by 50%.
After the bonus issue:

• Existing shares = 100
• Bonus shares received = 50
• Total shares held = 150
   

Who is Eligible for Bonus Shares?

A shareholder may be eligible to receive bonus shares if the following conditions are met:

• The shareholder owns the company's shares before the ex-date.
• The shareholder's name appears in the company's records on the record date.
• The shares are held in a valid Demat account.
• Bonus shares are given to both individual and institutional investors, as long as they qualify for the same. 
• The individuals who buy shares after the date when the share goes ex-bonus cannot claim bonus shares for that specific stock issuance.
   

Types of Bonus Shares 

The companies can choose to announce bonus shares or not. They can pick from 

1. Fully Paid Bonus Shares

• These are issued to shareholders without any additional payment.
• The shares are fully paid at the time of allotment.

2. Partly Paid Bonus Shares

• These are issued by converting partly paid shares into fully paid shares using the company's reserves.
• They help simplify the company's share capital structure.
   

Why Do Companies Issue Bonus Shares?

Companies may issue bonus shares for several reasons:

• To reward existing shareholders.
• To increase investor confidence.
• To improve share liquidity in the market.
• To make shares more affordable after a price adjustment.
• To distribute accumulated reserves without using cash.
• To support wider shareholder participation.

What Is the Record Date?

The record date is the cut-off day that a company fixes to determine which shareholders will be eligible for the upcoming bonus share issue. In simple terms: if you’re holding the stock in your demat account on that date, you qualify for the bonus. For example, when you see a company announce a bonus ratio (say 1:2) and mention a record date of 30 June, only the shareholders on the register as of that day will receive the extra shares.

It’s important because share ownership changes frequently - so the record date ensures the company locks in the list of eligible shareholders.

What Is the Ex-Date?

The ex-date (often called the “ex-bonus date” when dealing with bonus shares) is the first trading day after which new buyers of the stock are not eligible for the bonus issue. Usually, this falls one business day before the record date, given the trade settlement cycle.

Here’s the practical rule: if you want to make sure you get the bonus, buy the shares before the ex-date (or on the ex-date if the settlement allows), and hold through the record date. Miss that window and you’re out of luck - even if you buy the share the next day.
