The level of attention surrounding a company's Initial Public Offering (IPO) can range from highly positive to negative or may receive little notice at all. Ideally, there are two key factors that often draw the most attention: the roadshow period, when companies present their offering to investors and the allotment stage, when investors see whether shares have been credited to their respective demat accounts.

In some cases, you may not receive an allocation of shares. This could be due to high subscription, errors in your application form, or simply luck. Understanding these factors in advance can help you avoid common mistakes and improve the chances of a valid IPO application.

Most Common IPO Non-Allocation Reasons

Several factors can result in an IPO application not receiving share allotment. Here are a few common reasons behind non-allotment of shares:

Application not submitted successfully

In some cases, if you have tried to submit the application through the website or app, it may not have been submitted successfully. This commonly happens when you apply for the IPO after its application closing date. If your application is not successfully submitted, it will not be considered for share allotment.

Oversubscription

Oversubscription occurs when the number of applications exceeds the number of shares available in the IPO. Suppose the company offered 50 lakh shares in the market; they would then expect 50 lakh ASBA IPO applications. However, due to high demand, they received twice the number of applications they expected. As a result, some applicants receive fewer shares than they applied for, while others are not allocated any shares.

Insufficient funds in the bank account

ASBA blocks the bidding amount in your bank account. The amount is debited only if the shares are allotted. However, if the required amount is not available at the time of processing, the application won’t be considered for allotment of shares.

Multiple applications

As per the Securities and Exchange Board of India (SEBI), you can submit only one IPO application per PAN. If multiple applications are submitted using the same PAN, they will be rejected during the verification process.

Ways to reduce the chance of IPO non-allotment

Typically, IPO allotment depends on demand and allocation rules. However, you can take certain steps to ensure your application is submitted successfully.

Submit the application on time

Check the IPO closing date in the offer documents or on official exchange platforms. Mark it on your calendar and ensure you submit your application before it. Another effective way is to keep an eye on your broker’s mobile app notifications, as these reminders can help you track application timelines.

Fill out the application carefully

Complete the IPO application carefully to avoid any errors. Keep all essential details such as your PAN card, bank account details, and demat account numbers handy so you don’t have to scramble for them during the application process.

Maintain sufficient funds in the bank account

Make sure you maintain the required amount of funds in your bank account. It should cover both the bidding amount and the application cost. You can also consider opening a dedicated savings account for your IPO applications. This will keep the funds separate and ensure your application proceeds without interruption.

Consider using the ASBA facility

To avoid challenges in your IPO application, you can use the Application Supported by Blocked Amount (ASBA) facility for a streamlined process. With ASBA, the bid amount remains blocked in your bank account until the allotment is finalised.

Final checklist before applying for an IPO

When submitting your IPO application, keep the following points in mind to ensure the details are accurate and your application is submitted successfully.

Confirm the correct IPO name:

Ensure you select the correct IPO name. Especially when the companies belong to the same business group or have similar names.

Verify your name:

The name in your IPO application should match exactly with the name registered on your PAN and Aadhaar cards.

Check bank and demat account details:

Confirm that your bank account number and demat account numbers are correctly entered.

Review bid amount and available funds:

Double-check the bidding amount you have entered and make sure you have enough funds for the IPO through the ASBA process.

Confirm successful application submission:

Check whether the IPO application has been successfully submitted. Once you click submit, you should receive an SMS and email notification.

Summing it up

Applying for an IPO allows you to be part of a growing company and potentially earn profits from it. However, share allotment depends on several factors, including the number of applications received and the allocation process followed by the registrar. Even small errors in the application form may lead to rejection or non-allotment of shares.

To avoid any issues, you can consider using ASBA facility offered by IDFC FIRST Bank through the mobile banking app and the net banking platform. This will allow you to submit your application using your bank account while keeping funds securely blocked until the shares are allotted.
