Basis of Allotment in IPOs: How Shares Are Distributed
Initial Public Offerings (IPOs) often generate significant interest among investors, particularly when a company is perceived to have strong growth potential. However, submitting an IPO application does not guarantee that you will receive the shares you applied for. This is where the basis of allotment in IPO becomes important.
Thank you for reading this post, don't forget to subscribe!The basis of allotment is the framework used to determine how shares are distributed among investors after the IPO subscription period closes. Understanding this process can help investors set realistic expectations and better interpret allotment outcomes, especially in oversubscribed IPOs.
In this article, we explain the IPO allotment process, the factors that influence allotment, and how investors can check their IPO allotment status.
What Is the Basis of Allotment in an IPO?
The basis of allotment in an IPO refers to the methodology used by the registrar, in consultation with stock exchanges, to allocate shares to investors after the issue closes. The allotment process follows SEBI regulations and aims to ensure fair distribution among eligible applicants.
When an IPO is oversubscribed, shares may be allotted through a proportionate allocation method or a computerized draw of lots, depending on the investor category and the level of subscription.
What Is the Basis of Allotment?
The basis of allotment is a document that outlines how shares have been distributed among applicants in an IPO. It is finalized after the subscription period ends and before shares are credited to successful investors.
The document typically includes:
- Total number of applications received
- Number of shares applied for
- Subscription levels across investor categories
- Number of successful applicants
- Share allocation methodology
The basis of allotment ensures transparency and provides a clear explanation of how IPO shares are allotted across different investor segments.
Understanding Investor Categories in IPOs
Before discussing allocation, it is important to understand the categories under which IPO investors apply.
Retail Individual Investors (RIIs)
Retail investors applying for shares up to the prescribed limit fall under this category.
Non-Institutional Investors (NIIs)
This category includes investors applying above the retail limit.
Qualified Institutional Buyers (QIBs)
Institutional participants such as mutual funds, banks, insurance companies, and foreign institutional investors belong to this category.
SEBI regulations specify the portion of shares reserved for each category, and the allotment process is conducted separately within these segments.
How Does the IPO Allotment Process Work?
The IPO allotment process generally follows these steps:
Step 1: IPO Subscription Closes
Once the IPO bidding window closes, all applications are compiled and verified.
Step 2: Validation of Applications
The registrar reviews applications to identify valid and invalid bids. Applications may be rejected due to:
- Incorrect PAN details
- Insufficient funds in the bank account
- Multiple applications under the same PAN
- Technical errors during submission
Step 3: Determination of Subscription Levels
The registrar calculates how many times the IPO has been subscribed in each investor category.
Step 4: Finalization of Basis of Allotment
If demand exceeds the available shares, the registrar determines allocation according to applicable IPO share allotment rules and SEBI guidelines.
Step 5: Credit of Shares and Refunds
Successful applicants receive shares in their demat accounts, while blocked funds for unsuccessful applications are released.
How IPO Shares Are Allotted in Different Scenarios
The method of allotment depends on whether the IPO is undersubscribed, fully subscribed, or oversubscribed.
When an IPO Is Undersubscribed
If the number of shares applied for is lower than the shares offered, eligible applicants generally receive the quantity they applied for.
When an IPO Is Fully Subscribed
Investors typically receive shares based on the quantity applied for, subject to availability.
When an IPO Is Oversubscribed
Oversubscription occurs when investor demand exceeds the shares available for allocation.
In such cases, the basis of allotment becomes particularly important.
For retail investors, the objective is often to provide the minimum application lot to as many applicants as possible before allocating additional shares, subject to availability.
Understanding IPO Allotment in Oversubscribed Issues
Oversubscribed IPOs are common in the Indian primary market.
Consider the following example:
- Shares available for retail investors: 10 lakh
- Valid retail applications received: 20 lakh
Since demand exceeds supply, not every applicant can receive shares.
In such situations, allotment may involve:
- Distribution of minimum lots
- Computerized lottery systems
- Proportionate allocation methods where applicable
The exact methodology depends on subscription levels and regulatory guidelines.
This is one reason why receiving shares in a heavily subscribed IPO can be challenging even if the application was submitted correctly.
Key Factors Affecting IPO Allotment
Several factors influence an investor’s chances of receiving shares.
- Subscription Levels
The higher the oversubscription, the lower the probability of allotment.
- Investor Category
Retail, NII, and QIB allotments are conducted separately.
- Number of Valid Applications
Only valid applications participate in the allotment process.
- Lot Size
IPO allotment is generally based on application lots rather than individual shares.
- Regulatory Guidelines
SEBI regulations and exchange-approved allotment procedures govern share distribution.
IPO Share Allotment Rules Investors Should Know
Investors often assume that applying for a larger number of lots guarantees a higher chance of allotment. However, this may not always be the case, especially in highly oversubscribed retail categories.
Some important IPO share allotment rules include:
- Allotment is conducted category-wise.
- Only valid applications are considered.
- Registrars finalize allotment in consultation with stock exchanges.
- Oversubscribed issues follow approved allocation methodologies.
- Retail investors are generally considered separately from institutional applicants.
Understanding these principles helps investors approach IPO participation with realistic expectations.
How to Check IPO Allotment Status
After allotment is finalized, investors can verify their IPO allotment status through multiple channels.
Registrar’s Website
The IPO registrar usually provides an allotment status page where investors can enter:
- PAN number
- Application number
- DP ID and Client ID
Stock Exchange Websites
Investors may also check allotment information on stock exchange platforms.
Broker Platforms
Many online brokers provide IPO application tracking and allotment updates through their mobile applications and websites.
Common Reasons for Non-Allotment
Not receiving shares does not necessarily indicate a problem with the application.
Common reasons include:
- High oversubscription levels
- Limited shares available in the investor category
- Lottery-based allocation outcomes
- Invalid or rejected applications
In many popular IPOs, a large number of valid applicants may not receive allotment simply because demand exceeds available shares.
Practical Tips for Retail Investors Applying for IPOs
While allotment cannot be guaranteed, investors can improve the quality of their applications by:
- Ensuring PAN and demat details are accurate
- Maintaining sufficient funds for ASBA applications
- Applying within the specified IPO window
- Reviewing eligibility requirements carefully
- Tracking subscription levels before the issue closes
Most importantly, investors should evaluate the company’s fundamentals and prospectus rather than focusing solely on allotment probabilities.
Conclusion
The basis of allotment in IPO is an important component of the IPO ecosystem that ensures shares are distributed fairly among eligible applicants. Whether an IPO is fully subscribed or heavily oversubscribed, the allotment process follows established regulatory procedures designed to maintain transparency and investor confidence.
By understanding the IPO allotment process, the factors influencing allocation, and the applicable IPO share allotment rules, investors can make more informed decisions when participating in public offerings. While allotment outcomes are influenced by demand and availability, a clear understanding of how IPO shares are allotted can help investors navigate the IPO market with greater clarity.
