When the subscription list of a public issue closes, the most investor-sensitive phase of the offering begins. The issuer is now sitting on application money belonging to thousands of investors, none of whom yet hold a tradable security. The post-issue process — finalisation of the basis of allotment, credit of shares, refund of unsuccessful application money, statutory advertisements and the formal listing and commencement of trading — is governed by Chapter II and the general post-issue provisions of the SEBI (Issue of Capital and Disclosure Requirements) Regulations, 2018, principally Regulations 45, 49, 50, 51 and 52, read with the listing obligations under the Securities Contracts (Regulation) Act, 1956 and Section 40 of the Companies Act, 2013. This chapter maps the timeline from issue closure to listing, the duties cast on the issuer and lead managers, and the heavy judicial gloss that the Supreme Court has placed on these obligations, most famously in Sahara India Real Estate Corporation Ltd. v. SEBI.
What the Post-Issue Stage Covers
The expression “post-issue” refers to the cluster of activities that follow the closing of the subscription list of a public issue (the day of closure being conventionally denoted as T). At that moment the issuer holds application moneys but the securities are neither allotted nor tradable. The ICDR framework treats this window as a regulated process with hard deadlines because investors’ funds are locked, the market is waiting for price discovery on listing, and any slippage erodes confidence in the primary market. The principal steps are: validation and reconciliation of applications; determination of the basis of allotment in consultation with the designated stock exchange; credit of allotted securities to demat accounts and unblocking or refund of money to unsuccessful and partially successful applicants; issue of the mandatory post-issue advertisement; filing of post-issue reports by the lead manager; and finally listing and commencement of trading.
These obligations sit on top of the eligibility and disclosure norms studied earlier in this series. The conditions that an issuer must satisfy before it ever reaches this stage are dealt with in Eligibility for IPO and the document on which the whole offering rests is examined in Disclosure in the Draft Red Herring Prospectus. The post-issue chapter is where the promises made in those documents are tested against performance. For the overall scheme of the Regulations, see the SEBI ICDR notes hub.
The Minimum Subscription Gateway: Regulation 45
Before any allotment can be made, the issue must clear the minimum subscription threshold. Regulation 45 of the ICDR Regulations requires that the minimum subscription to be received in an issue (other than an offer for sale of specified securities) shall be at least ninety per cent of the offer through the offer document. Where the issuer does not receive the minimum subscription, or where subscription level falls below ninety per cent after the closure of the issue on account of withdrawal of applications, non-receipt of funds against blocked applications, technical rejections or any other reason, the entire application money must be refunded.
The refund of application money on failure of the issue must be made within the period prescribed by SEBI from time to time (currently within four working days of issue closure under the streamlined timeline), failing which the issuer and every director who is an officer in default become liable to repay the money with interest. The minimum subscription condition is the statutory recognition that a half-subscribed issue is not a viable public offering; the law would rather return the money than saddle the issuer and the market with an illiquid, under-capitalised float. For small and medium enterprise issues routed through the SME platform, an analogous minimum-subscription obligation operates, and SEBI has, through Regulation 86 and connected provisions, calibrated the consequences for that segment.
Allotment Procedure and Basis of Allotment: Regulation 49
Regulation 49 prescribes how allotment is to be carried out once minimum subscription is satisfied. Two structural conditions stand out. First, in an initial public offer, the issuer shall not make an allotment if the number of prospective allottees is less than one thousand. This floor exists to ensure genuine public dispersal of shareholding — a public issue that ends up in very few hands is not, in substance, a public issue at all, and would also fail the minimum public shareholding norms under the listing framework. Second, the issuer shall not make any allotment in excess of the specified securities offered through the offer document, except where there is oversubscription, and then only for the limited purpose of rounding off to make allotment, in consultation with the designated stock exchange.
The basis of allotment is finalised by the issuer and the registrar to the issue in consultation with the designated stock exchange, and where the issue is oversubscribed, allotment in the retail and non-institutional categories proceeds on a proportionate basis within the legal minimum bid lot, subject to reservation and the minimum-application-size rules. The procedure is illustrated in the schedules to the Regulations. The drafting deliberately removes discretion: allotment is a mechanical, transparent exercise checked by the exchange, precisely so that the kind of manipulation seen in the IPO demat scam (discussed below) cannot recur. The definitions that anchor these terms — “designated stock exchange”, “retail individual investor”, “net offer” — are unpacked in Definitions and Scope.
Allotment, Refund and Payment of Interest: Regulation 50
Regulation 50 fixes the outer time limits and the interest consequences of delay. The issuer and the lead manager(s) must ensure that the specified securities are allotted and/or the application moneys are refunded or unblocked within such period as may be specified by SEBI. The legacy outer limit was fifteen days from the date of closure of the issue; under the compressed timeline this has been brought forward substantially, with refunds and unblocking effected within the first few working days after closure so that the entire cycle fits inside the T+3 listing window.
The teeth of Regulation 50 lie in the interest provision: if the issuer fails to make allotment, or to refund or unblock application moneys within the prescribed period, it is liable to pay interest at the rate of fifteen per cent per annum to the investors for the period of delay. This statutory interest rate is not arbitrary — it mirrors the rate the Supreme Court itself imposed in Sahara India Real Estate Corporation Ltd. v. SEBI, (2013) 1 SCC 1, where the Court directed the Sahara group to refund over Rs 24,000 crore collected through optionally fully convertible debentures together with interest at fifteen per cent per annum. The choice of fifteen per cent across the regulatory and judicial landscape signals that delayed refund is treated as a serious dereliction, not a technical lapse. The mechanics of how money flows into and out of the issue account are tied to the payment method (ASBA / UPI), where moneys remain blocked rather than debited until allotment, dramatically reducing refund risk.
ASBA, UPI and the Elimination of Refund Float
A structural reform that underpins the entire modern post-issue timeline is the Application Supported by Blocked Amount (ASBA) mechanism, now mandatory for all categories of investors in public issues, and the UPI block facility for retail applications. Under ASBA, the application money is not paid out of the investor’s account at the time of bidding; it is merely blocked in the bank account and is debited only to the extent of allotment. Where there is no allotment, or partial allotment, the block is simply released — there is no refund cheque to dispatch and no float to reconcile.
This eliminates the classic source of post-issue delay and litigation: the physical refund process. It also closes the regulatory gap that the old refund-cheque regime created, where money sat with the issuer’s bankers and investors waited weeks for repayment. By converting “refund” into “unblocking”, SEBI made the four-day and T+3 timelines operationally feasible. The interest liability under Regulation 50 now attaches not merely to delayed refunds but to delayed unblocking, and SEBI’s circulars provide for compensation to investors at a fixed per-day rate where the bankers or intermediaries fail to unblock funds on time, ensuring that investor money cannot be held hostage by back-office failure.
Post-Issue Advertisements: Regulation 51
Regulation 51 requires the post-issue lead manager to ensure that a post-issue advertisement giving details relating to subscription, basis of allotment, number, value and percentage of all applications including ASBA, number, value and percentage of successful allottees for all applications, date of completion of dispatch of refund or unblocking instructions, and date of credit and filing of the listing application is released within a stipulated period after the basis of allotment is finalised. The advertisement must appear in newspapers in the manner specified.
The object is transparency: every investor and the market at large should be able to see how the issue was subscribed and how shares were allocated, before trading begins. A public, contemporaneous record of the allotment basis is also a deterrent against manipulation, because any deviation between the disclosed proportionate basis and the actual allotment becomes immediately auditable. The post-issue advertisement complements the post-issue reports that the lead manager files privately with SEBI under Regulation 52, the difference being that the advertisement is the public-facing disclosure while the reports are the regulator-facing compliance filing.
Post-Issue Responsibilities of Lead Managers: Regulation 52
Regulation 52 places continuing post-issue duties on the lead manager(s) and requires them to be associated with the issue until the subscribers have received the securities or the application money has been refunded or unblocked. The lead manager must regularly monitor the redressal of investor grievances arising out of the post-issue activities such as allotment, refund, unblocking, dispatch and listing.
The Regulation prescribes a reporting cadence. The lead manager must file a final post-issue report with SEBI in the specified format (Part A of the relevant Schedule) along with a due diligence certificate within seven days of the date of finalisation of the basis of allotment, or within seven days of the refund of money in case of failure of the issue. There are also interim reporting obligations tied to issue closure. Crucially, where an issue is managed by more than one lead manager, the rights, obligations and responsibilities of each — including for allotment, refund, underwriting and disclosure — must be predetermined and disclosed in the offer document, so that accountability for the post-issue process is never diffused. The lead manager’s due diligence obligation here is continuous with the obligation it owes at the disclosure stage, examined in Disclosure in the Draft Red Herring Prospectus.
Listing Permission: SCRA Section 21 and Section 40 of the Companies Act
Allotment and listing are legally interdependent. Under Section 21 of the Securities Contracts (Regulation) Act, 1956, where securities are listed on a recognised stock exchange on the application of any person, that person must comply with the conditions of the listing agreement (now the SEBI (LODR) Regulations, 2015). The listing permission is the gateway through which an allotted-but-unlisted security becomes tradable.
The companion provision is Section 40 of the Companies Act, 2013 (the successor to Section 73 of the 1956 Act), which provides that every company making a public offer shall, before making the offer, make an application to one or more recognised stock exchanges and obtain permission for the securities to be dealt with; and that any allotment made on the basis of such prospectus shall be void if listing permission is not granted within the prescribed period. Section 40 also requires that the application money be kept in a separate bank account and refunded if listing permission is refused or not obtained, with interest for delay. This statutory architecture explains why the ICDR timeline is so tightly drawn: an allotment that is not followed by timely listing is not merely commercially disappointing — it is, in law, capable of being rendered void, forcing a refund.
The Compressed Listing Timeline: From T+6 to T+3
The single most consequential operational reform to the post-issue process in recent years is the reduction of the listing timeline. Historically, securities were required to be listed within six working days of issue closure (the T+6 timeline). By Circular SEBI/HO/CFD/TPD1/CIR/P/2023/140 dated 9 August 2023, SEBI reduced this to three working days (T+3), applicable on a voluntary basis for public issues opening on or after 1 September 2023 and on a mandatory basis for those opening on or after 1 December 2023.
Under the T+3 regime, T is the day of issue closure; the basis of allotment is finalised, allotment is credited and unblocking is completed in the first working days thereafter, the listing application and post-issue advertisement follow, and trading commences on T+3. The compression is only feasible because of the digitisation of the application chain — mandatory ASBA, UPI blocking, electronic flow of data between registrars, bankers, depositories and exchanges. The reform reduces the period for which investor money is locked, lowers market risk between pricing and listing, and brings the Indian primary market to among the fastest listing cycles globally. The detailed activity-wise schedule is annexed to the circular and must be disclosed in the offer document.
The Sahara Refund Jurisprudence
No discussion of post-issue refund obligations is complete without Sahara India Real Estate Corporation Ltd. v. SEBI, (2013) 1 SCC 1 (decided 31 August 2012). Two Sahara group companies had raised over Rs 24,000 crore from roughly three crore investors through optionally fully convertible debentures (OFCDs), characterising them as private placements outside SEBI’s reach. The Supreme Court, per Radhakrishnan and Khehar JJ, held that an offer made to more than fifty persons is deemed a public issue and attracts the full listing and investor-protection machinery; SEBI had jurisdiction; and the OFCDs ought to have been listed.
The Court’s post-issue remedy is the enduring lesson: it directed the Sahara companies to refund the entire amount collected to the investors with interest at fifteen per cent per annum, to be deposited with SEBI, and laid down a mechanism for verification and repayment. Sahara is the judicial source of the fifteen-per-cent benchmark now embedded in Regulation 50, and it stands for the proposition that the obligation to refund money to public investors, where the issue process is non-compliant, is absolute and enforceable by the highest court. It is the doctrinal backbone of the entire refund-and-interest regime. The threshold question of what makes an offer “public” and therefore subject to these obligations is traced in Introduction and Object.
Allotment Integrity: Lessons from the IPO Demat Scam
The integrity of the allotment process — the core concern of Regulation 49 — was tested by the IPO demat scam of 2003–2005. SEBI’s investigation revealed that operators, most notoriously Roopalben Panchal and associates, had cornered shares reserved for the retail category by applying through thousands of fictitious or benami demat accounts, defeating the proportionate-allotment safeguard that is meant to spread shares widely among genuine retail investors. Depository participants, including Karvy Stock Broking, were found to have opened large numbers of accounts in disregard of know-your-client norms.
SEBI responded with ex-parte interim orders restraining the operators, followed by disgorgement of the unlawful gains together with interest, and its first large-scale investor-compensation exercise. The episode directly shaped the post-issue framework: it accelerated the move to PAN-based and KYC-verified applications, the mandatory demat route, ASBA blocking, and the transparent, exchange-supervised basis of allotment now codified in Regulation 49. The case demonstrates that the post-issue rules are not mere paperwork; they are the mechanism by which the law guarantees that the allotment an investor sees in the post-issue advertisement is the allotment that actually happened.
Strict Construction of Investor-Protection Provisions
A recurring judicial theme is that SEBI’s investor-protection provisions are construed strictly and are not lightly diluted on equitable grounds. In Nirma Industries Ltd. v. SEBI, AIR 2013 SC 2360 : (2013) 8 SCC 20, the Supreme Court, though dealing with withdrawal of a public offer under the Takeover Regulations, refused to read in an open-ended discretion to escape a public obligation owed to investors, even where the acquirer pleaded that fraud had been discovered after the public announcement. The Court emphasised that obligations cast for the protection of the investing public must be performed and cannot be wriggled out of through a liberal interpretation that defeats the regulatory object.
The same interpretive posture governs the post-issue obligations. The deadlines in Regulations 49, 50 and 52, the minimum-subscription floor in Regulation 45, and the listing-permission requirement under Section 40 of the Companies Act are read as mandatory, with the consequences — interest at fifteen per cent, voiding of allotment, refund — following automatically on breach. The jurisprudence treats the primary-market investor as a protected class whose money the law will not allow to be locked or lost through procedural slippage.
Consequences of Post-Issue Default
The consequences of failing the post-issue obligations are layered. Civil/statutory: interest at fifteen per cent per annum under Regulation 50 for delayed allotment, refund or unblocking; compensation to investors at the per-day rate fixed in SEBI circulars for delayed unblocking; and, under Section 40 of the Companies Act, voiding of the allotment and mandatory refund with interest where listing permission is not obtained. Regulatory: action under Section 11 and 11B of the SEBI Act, including directions, disgorgement and monetary penalties, and action against the lead manager and other intermediaries for breach of their continuing post-issue duties under Regulation 52.
For the lead manager, the post-issue stage is a zone of acute liability because its due-diligence certificate and post-issue reports are filed with SEBI, and any misstatement or failure to monitor grievances can attract intermediary action. For the issuer’s directors, default exposes them to officer-in-default liability. The cumulative design ensures that every actor in the chain — issuer, directors, lead manager, registrar, bankers and depositories — carries a defined, enforceable slice of responsibility for getting the investor’s shares credited and money returned on time, which is ultimately what the post-issue regime exists to achieve.
Frequently asked questions
Within how many days must securities be listed after a public issue closes?
Under the current SEBI regime the listing timeline is T+3 working days (T being the day of issue closure), reduced from the earlier T+6 by Circular SEBI/HO/CFD/TPD1/CIR/P/2023/140 dated 9 August 2023 — voluntary for issues opening on or after 1 September 2023 and mandatory for those opening on or after 1 December 2023. Trading commences on T+3.
What is the minimum subscription requirement and what happens if it is not met?
Regulation 45 of the ICDR Regulations requires minimum subscription of at least ninety per cent of the offer (other than an offer for sale). If it is not received, the issue fails, no shares are allotted, and the entire application money must be refunded or unblocked within the prescribed period, with interest for delay.
What rate of interest is payable for delayed allotment or refund?
Regulation 50 provides for interest at fifteen per cent per annum for the period of delay in allotment, refund or unblocking. This mirrors the rate the Supreme Court imposed in Sahara India Real Estate Corporation Ltd. v. SEBI, (2013) 1 SCC 1, when directing refund of OFCD collections to investors.
Why must an IPO have at least 1,000 allottees?
Regulation 49 bars allotment in an initial public offer if the number of prospective allottees is less than one thousand. The floor ensures genuine public dispersal of shareholding, consistent with the minimum-public-shareholding philosophy; an issue ending in very few hands is not, in substance, a public issue.
How does ASBA change the post-issue refund process?
Under Application Supported by Blocked Amount (ASBA) and UPI blocking, application money is only blocked in the investor's bank account, not paid out, and is debited only to the extent of allotment. Where there is no allotment, the block is simply released, eliminating refund float and making the compressed T+3 timeline feasible.
What is the legal effect of failing to obtain listing permission after allotment?
Under Section 40 of the Companies Act, 2013 (formerly Section 73 of the 1956 Act) read with Section 21 of the Securities Contracts (Regulation) Act, 1956, an allotment made on a public-offer prospectus becomes void if listing permission is not obtained within the prescribed period, and the application money must be refunded with interest.
