What is Basis of Allotment in IPO: Meaning, Process

The primary market in India is a hub of activity for investors looking to capitalize on new opportunities. When a company decides to go public, the excitement often centers around the subscription levels. However, for a retail investor, the most critical document issued after the bidding process ends is the basis of allotment. This document serves as the official rulebook that dictates who receives shares and how many are distributed among the millions of applicants. Understanding the basis of allotment is essential for anyone navigating the complexities of modern public offerings.

Understanding the Fundamentals: What is IPO

Before diving into the technicalities of the allotment mechanism, it is important to clarify what is ipo. An Initial Public Offering is the structured process where a private company offers its shares to the general public for the first time. This transition allows a company to raise capital from a diverse pool of investors, including individuals, institutions, and high net worth entities. Once the IPO process is completed, the company becomes listed on stock exchanges like the NSE or BSE, and its shares become tradable in the secondary market.

The process begins with the company filing a Draft Red Herring Prospectus with SEBI. This document outlines the company financials, business model, and the purpose of the fundraise. Once approved, the company opens a subscription window, usually for three to five working days, during which investors place their bids within a specified price band.

Defining Basis of Allotment in IPO

The basis of allotment is a formal document produced by the registrar of the issue in consultation with the stock exchange. It outlines the final allocation strategy for the shares offered in the IPO. This document is published after the subscription period ends and once the final issue price is determined through the book building process.

In simple terms, if an IPO is oversubscribed, the company cannot give shares to everyone who applied. The basis of allotment explains the logic used to decide the winners of the lottery and the quantity of shares assigned to each category of investor. It provides transparency and ensures that the company and its lead managers adhere to SEBI guidelines during the distribution phase.

The Critical Role of the Registrar

The registrar of an IPO plays a pivotal role in finalizing the basis of allotment. Entities like Link Intime or KFintech are appointed by the company to manage the application data. Their primary responsibility is to compile every single bid received through various banking and brokerage channels.

After the bidding window closes, the registrar begins a rigorous verification process. They check for duplicate applications, verify Permanent Account Number details, and ensure that the bank funds are properly blocked through the Application Supported by Blocked Amount facility. Any application found with incorrect details or multiple bids from the same PAN is rejected at this stage. Once the valid applications are identified, the registrar calculates the subscription ratio for each category and prepares the basis of allotment for exchange approval.

Classification of Investor Categories

Shares in an IPO are not distributed randomly across the entire pool of applicants. Instead, SEBI mandates specific quotas for different types of investors to ensure fair market participation. The basis of allotment handles each of these categories differently.

Retail Individual Investors are those whose total application value does not exceed two lakh rupees. In most cases, 35 percent of the total issue is reserved for this category. Non Institutional Investors, often referred to as high net worth individuals, apply for amounts exceeding two lakh rupees and usually have a 15 percent reservation. Qualified Institutional Buyers, such as mutual funds, insurance companies, and foreign institutional investors, typically account for 50 percent of the offering.

Some IPOs also include specific reservations for employees of the company or existing shareholders of a parent entity. The basis of allotment will detail the oversubscription level and the allotment ratio for each of these distinct buckets.

The Basis of Allotment Process: Step by Step

The journey from the closing of the subscription to the final listing involves several technical steps where the basis of allotment is the centerpiece.

First, the registrar concludes the verification of all electronic bid data against the actual funds blocked in investor bank accounts. Once the net valid applications are determined, they calculate the oversubscription ratio. For instance, if the retail portion is subscribed 10 times, it means there are ten applicants for every one share available in that category.

Second, the registrar applies the allotment logic. For the retail category, the current SEBI guidelines focus on maximizing the number of unique allottees. This means that in an oversubscribed scenario, the system attempts to give at least one minimum lot to as many individual applicants as possible. If the number of unique applicants exceeds the number of lots available, a computerized lottery system is triggered.

Third, the basis of allotment document is drafted. This document shows a table with various bid sizes, the number of applications received for each size, and the ratio of allotment. It might show, for example, that for a certain bid size, 1 out of every 15 applicants was selected through the lottery.

Fourth, the document is submitted to the designated stock exchange for approval. Once the exchange verifies that the process followed all regulatory norms, the basis of allotment is finalized, and the registrar begins the process of crediting shares and releasing refunds.

Why the Basis of Allotment Matters for Retail Investors

For a retail participant, the basis of allotment is the definitive source of truth. Many investors mistakenly believe that applying for more lots in the retail category increases their chances. However, the basis of allotment proves that the lottery is conducted based on unique PAN applications.

By reviewing this document, investors can understand the intensity of the competition. It explains why they might have received zero shares despite a valid application. It also ensures that the process was not biased toward larger retail applications, as the lottery system treats a one lot application and a thirteen lot application with the same priority when the objective is to maximize the number of allottees.

The Mathematical Logic of the Lottery System

In highly oversubscribed IPOs, the demand is so high that even the minimum lot cannot be given to every valid applicant. The basis of allotment will explicitly state the lottery ratio. If the ratio is 1:25, it means that for every 25 valid applications, only one was randomly selected by the software to receive the minimum lot.

This randomness is a core feature of the Indian IPO market designed to protect small investors from being crowded out by those with more capital. The basis of allotment provides the mathematical proof that this lottery was executed fairly and across all valid bid sizes within the retail category.

How to Check Allotment Status After Finalization

Once the basis of allotment is finalized, which typically happens within four to six working days after the IPO closes, investors can check their individual status. The registrar websites provide a dedicated portal where one can enter their PAN, application number, or DP ID to see the result.

The status will indicate whether the application was successful. If shares were allotted, they will be credited to the demat account within one to two days before the listing date. If not allotted, the bank will receive a message to unblock the funds, making them available for other investments.

Avoiding Common Rejection Pitfalls

A valid application is the prerequisite for entering the allotment pool described in the basis of allotment. Many investors find their names missing from the lottery because of simple errors. Using the same PAN to apply multiple times is a frequent reason for rejection. Even if the applications are through different brokers or demat accounts, the registrar will consolidate them by PAN and disqualify all of them.

Other common issues include mismatches between the name on the PAN card and the bank account, or failing to approve the UPI mandate on time. Ensuring that the bank account has sufficient funds until the allotment date is also vital, as any failure to block the amount will lead to an immediate rejection.

The Importance of Professional Investment Advisory

Navigating the primary market requires more than just understanding the technical steps of allotment. Every year, dozens of companies hit the market, but not all of them offer sustainable value. This is where a SEBI registered investment advisory becomes invaluable. These professionals analyze the Red Herring Prospectus, evaluate company valuations, and study industry trends to help investors choose which IPOs are worth the effort.

An investment advisory service provides deep insights that go beyond the grey market hype. They help investors understand the long term prospects of a company rather than just focusing on potential listing gains. By following a disciplined strategy guided by expert research, investors can build a diversified portfolio that includes quality IPOs while minimizing exposure to speculative risks.

Final Reflections on Basis of Allotment

The basis of allotment is a testament to the transparency and efficiency of the Indian capital markets. It transforms a complex, high demand bidding process into a structured and fair distribution mechanism. By understanding this document and the process behind it, investors can set realistic expectations and improve their procedural accuracy.

While the lottery system means that allotment is never guaranteed in a popular IPO, following the right steps and seeking guidance from a professional investment advisory can significantly enhance an investor’s journey. As the market continues to evolve with faster timelines like T plus three listing, the basis of allotment remains the cornerstone of investor trust in the public offering process.
