When a company taps the public markets, the law insists that those who built and control it must keep meaningful capital at risk alongside the investing public. That insistence takes concrete shape in Regulations 14 to 22 of the Securities and Exchange Board of India (Issue of Capital and Disclosure Requirements) Regulations, 2018 — the chapter on promoters' contribution and lock-in. The architecture is deceptively simple: promoters must bring at least twenty per cent of the post-issue capital to the table, that contribution must be made up of clean, eligible securities, and the locked capital cannot be sold for a defined period after listing. Beneath that simplicity sits a dense lattice of definitions, exemptions, ineligibility filters, and transfer carve-outs that examiners love to probe. This chapter unpacks each limb against the bare provisions and the leading jurisprudence on who is a promoter and what is a security.
Why lock-in exists: rationale and placement in the scheme
The promoters' contribution and lock-in requirements sit in Chapter II of the SEBI (ICDR) Regulations, 2018, which governs initial public offers on the main board. They are the regulatory expression of a simple market-integrity idea: a person who controls and profits from a company should not be permitted to raise public money and then exit at the first opportunity, leaving outside shareholders to bear the residual risk of an enterprise the insiders have already abandoned. Lock-in forces promoters to retain “skin in the game” for a period after listing, aligning their incentives with those of the public investors who subscribed on the strength of the promoters' stewardship.
The framework rests on two pillars. The first, in Regulation 14, is a quantitative floor — promoters must collectively hold at least twenty per cent of the post-issue capital. The second, in Regulations 16 and 17, is a temporal restraint — that contribution, and a portion of the rest of the pre-issue capital, cannot be sold for a defined lock-in period. Between these two pillars sits Regulation 15, an integrity filter that disqualifies tainted or recently acquired securities from counting toward the minimum. The chapter then closes with the mechanics of how lock-in is recorded, when locked securities may be pledged, and when they may be transferred. To understand any of this you must first be secure in the underlying vocabulary, which is why this chapter cross-refers to the definitions and scope and the broader SEBI ICDR Regulations hub.
Who is a 'promoter' and 'promoter group'
The lock-in obligations attach to a defined class, so the threshold question is always: who is a promoter? Regulation 2(1)(oo) of the ICDR Regulations defines a “promoter” as a person named as such in the offer document or in the issuer's annual return, or a person who is in control of the issuer directly or indirectly, or in accordance with whose advice, directions or instructions the board of directors is accustomed to act — with the familiar carve-out that a person acting merely in a professional capacity is not thereby a promoter. Regulation 2(1)(pp) then defines the “promoter group” expansively to capture relatives of the promoter, bodies corporate in which the promoter holds twenty per cent or more, and bodies corporate that hold twenty per cent or more in the promoter, weaving a net wide enough to prevent contribution and lock-in obligations from being side-stepped through affiliated vehicles.
Because “control” is the fulcrum of promoter status, the jurisprudence on control under the cognate takeover regime is instructive. In Subhkam Ventures (I) Pvt. Ltd. v. SEBI, the Securities Appellate Tribunal in its 2010 order held that “control” connotes proactive, positive power to direct a company's affairs rather than the merely reactive or protective veto rights an investor takes to safeguard its money; on that reasoning, standard affirmative or negative covenants do not by themselves confer control. The Supreme Court later disposed of the appeal by consent without affirming the reasoning, expressly leaving the question of law open, so Subhkam is persuasive rather than binding — but it remains the most cited articulation of the proactive-control test that shapes who is classified as a promoter in the first place.
The twenty per cent floor: Regulation 14
Regulation 14(1) is the heart of the chapter. It requires that the promoters of the issuer shall contribute to a public issue an amount not less than twenty per cent of the post-issue capital. Where the issue is wholly an offer for sale, or a composite issue, the regulation is read so that the promoters' aggregate holding after the issue is not less than twenty per cent. The contribution must be brought either through equity shares or, where the issue is of convertible securities, through the relevant securities; and where the conversion price is not determined, the promoter undertakes to subscribe at the price ultimately fixed.
The regulation has been liberalised to address a recurring practical difficulty: many maturing companies, especially those backed by venture and private-equity capital, simply do not have promoters holding twenty per cent by the time they list. The proviso to Regulation 14 therefore allows the shortfall in the twenty per cent to be met — up to a maximum of ten per cent of the post-issue capital — by specified institutional investors such as alternative investment funds, foreign venture capital investors, scheduled commercial banks, public financial institutions and insurers registered with the IRDAI, without those entities being branded as promoters. SEBI further widened this list so that any non-individual public shareholder holding at least five per cent of the post-issue capital, and any promoter-group entity other than the promoter, may also plug the gap. Critically, Regulation 14 does not apply where the issuer has no identifiable promoter — the professionally managed, widely held company that no single person controls is exempt from the minimum-contribution discipline altogether. The interaction of this floor with the wider listing gateway is taken up in eligibility for IPO.
Tainted capital: securities ineligible under Regulation 15
A twenty per cent floor would be meaningless if it could be filled with shares the promoter acquired cheaply on the eve of the issue or received without parting with real value. Regulation 15 is the integrity filter that screens out such securities from counting toward the minimum promoters' contribution. Broadly, the following are ineligible: equity shares acquired during the preceding three years for consideration other than cash, where revaluation of assets or capitalisation of intangible assets was involved, or which resulted from a bonus issue out of revaluation reserves or unrealised profits or against shares ineligible for the purpose; equity shares acquired by promoters during the one year immediately preceding the filing of the draft red herring prospectus at a price lower than the issue price, unless the difference is brought in; securities pledged with any creditor; and shares for which the full subscription money has not been paid.
SEBI has refined the one-year, lower-price test so that the comparison price is computed after adjusting for intervening corporate actions such as bonus issues and share splits, closing a loophole by which a cheap pre-IPO round could be disguised. The policy thread running through Regulation 15 is that only genuine, fully paid, arm's-length and untainted capital should anchor a promoter's commitment. Where a promoter's holding is partly composed of ineligible securities, the eligible balance alone counts toward the twenty per cent, and any shortfall must be made good through fresh eligible contribution before the issue can proceed — a point that feeds directly into the diligence reflected in the draft red herring prospectus disclosures.
Locking the contribution: Regulation 16
Once eligible promoters' contribution has been brought in, Regulation 16 freezes it. The position changed materially with the SEBI (ICDR) (Third Amendment) Regulations, 2021, which took effect for issues opening on or after the relevant date in 2022. Before the amendment, the minimum promoters' contribution was locked in for three years from the date of allotment; the amendment halved the ordinary lock-in to eighteen months.
The current scheme works on a bifurcated test. The minimum promoters' contribution — that is, the twenty per cent — is locked in for eighteen months from the date of allotment in the public issue. However, the longer three-year lock-in is retained in a targeted situation: where more than fifty per cent of the fresh issue proceeds are proposed to be utilised for capital expenditure (the classic greenfield or expansion project), the minimum contribution remains locked in for three years. The logic is that where public money is being deployed into long-gestation projects, promoters should be tied in for the period during which the project's success or failure becomes apparent. SEBI's stated rationale, when it relaxed the period, was that the original three-year norm pre-dated the maturing of Indian capital markets and had become an unnecessary friction for offer-for-sale and non-capex fund-raising, where eighteen months adequately signals commitment.
Excess promoter holding and the rest of pre-issue capital
Lock-in does not stop at the twenty per cent. Promoter holding in excess of the minimum contribution is also restrained, but for a shorter period. Following the 2021 amendment, the excess holding of promoters — the portion above the twenty per cent floor — is locked in for six months from the date of allotment, down from the earlier one year. This shorter restraint recognises that the integrity objective is largely served by the core minimum, while still preventing an immediate post-listing flood of promoter stock.
Regulation 17 then turns to the pre-issue capital held by persons other than the promoters. The entire pre-issue equity share capital held by such persons is, as a general rule, locked in for six months from the date of allotment (again reduced from the pre-amendment one year), with familiar exceptions for equity held by a venture capital fund, alternative investment fund or foreign venture capital investor for the prescribed period, and for shares held under approved employee benefit schemes. The combined effect of Regulations 16 and 17 is a tiered cliff: the bulk of pre-issue capital becomes freely tradable at six months, the promoter excess at six months, and the core minimum contribution at eighteen months — or three years where significant capital expenditure is funded. Examiners frequently test the candidate's ability to map a given shareholder to the correct tier, so the distinction between minimum contribution, promoter excess, and non-promoter pre-issue capital must be held precisely.
Computing the floor and fixing the clock
Two computational points cause disproportionate confusion. First, the twenty per cent is measured against the post-issue capital, not the pre-issue capital — so a promoter assessing compliance must work backward from the diluted, post-listing share count, taking into account the fresh issue, any offer for sale, and the conversion of outstanding convertibles. Where the issue includes convertible securities whose conversion price is not yet known, the promoter's undertaking to subscribe operates as a forward commitment to maintain the floor.
Second, the lock-in clock under both Regulations 16 and 17 runs from the date of allotment in the public issue, a single fixed reference point, rather than from the date each parcel of shares was originally acquired. This uniform start date simplifies depository administration and prevents promoters from arguing that long-held shares should be treated as already “seasoned.” The only material departure is the capital-expenditure limb of Regulation 16, where the three-year period is similarly anchored to allotment but applies because of how the proceeds are deployed, not because of when the shares were acquired. Getting the reference date right matters for every downstream question — pledge, transfer, and the disclosures that must accompany the offer, which are detailed in the red herring prospectus disclosures.
Recording the restraint: inscription of non-transferability
Lock-in is only as good as its enforcement at the level of the depository system. The regulations require that the specified securities subject to lock-in carry an inscription or recording of their non-transferability for the duration of the lock-in period. In a dematerialised market this is achieved by the depository flagging the relevant securities so that they cannot be debited from the holder's account until the lock-in expires. The certificates or the demat records must reflect both the fact of lock-in and the date of its expiry.
SEBI has been refining this mechanism. Recognising the practical impossibility, in certain situations, of creating a conventional lock-in flag — for instance where pre-issue shares held by non-promoters are already pledged — the Board introduced a facility for depositories to instead record such securities as “non-transferable” for the balance of the applicable lock-in period, with an automatic re-locking for the residual period on invocation or release of a pledge. The objective is to ensure that the economic restraint survives even where the standard system flag cannot be applied, so that no parcel of locked capital slips into free float ahead of time. This administrative layer is what gives the substantive lock-in periods their teeth.
Pledging locked-in securities: Regulation 21
A strict reading of lock-in would prevent promoters from doing anything with their frozen shares, but the regulations make a calibrated concession for financing. Regulation 21 permits specified securities that are otherwise locked in to be pledged with a scheduled commercial bank, a public financial institution, a systemically important non-banking financial company or a housing finance company — but only as collateral security for a loan, and only where two conditions are met. The pledge must be one of the terms of sanction of the loan, and, critically, the loan must have been granted to the issuer company itself for the purpose of financing one or more of the objects of the issue. Where the pledged securities form part of the minimum promoters' contribution, an additional safeguard applies: the loan must have been granted to the issuer for financing one or more of the objects of the issue.
The design ensures that the privilege of pledging frozen stock is channelled toward the very project for which public money was raised, not toward the promoter's unrelated personal borrowing. The lock-in is not extinguished by the pledge — it continues to run, and on invocation the pledgee takes the securities subject to the residual lock-in. This is consistent with the broader scheme that the integrity restraint should follow the securities through changes in custody, a theme that connects to the parallel disclosure and continuous-obligation regime explored across the SEBI ICDR hub.
Transferring locked-in securities: Regulation 22
Just as Regulation 21 carves out pledge, Regulation 22 carves out a limited class of transfers. Locked-in specified securities held by promoters may be transferred inter se among promoters, or to a person of the promoter group, or to a new promoter, provided the lock-in continues in the hands of the transferee for the remaining period — the transfer changes the holder, not the duration of the restraint. Similarly, securities held by persons other than promoters and locked in under Regulation 17 may be transferred to any other person holding such securities subject to the continuance of the lock-in in the transferee's hands.
A further carve-out accommodates the takeover regime: transfers of locked-in securities are permitted in connection with an open offer made under the SEBI (Substantial Acquisition of Shares and Takeovers) Regulations, 2011, or in compliance with other applicable law, again with the lock-in surviving the transfer where required. The unifying principle is that lock-in restrains the liquidation of promoter capital into the public market, not the orderly reorganisation of who holds it within a defined circle, and not the operation of the takeover code under which control may legitimately change hands. The interplay of lock-in with a change of control under the takeover regulations is precisely where the Subhkam debate over what constitutes “control” becomes practically important.
Application to FPOs and further issues
The contribution and lock-in discipline is not confined to the first public offer. In a further public offer (FPO), the same architecture applies: where the promoters' post-issue holding would fall below twenty per cent, they must bring minimum contribution, and the 2021 amendment extended the relaxed lock-in to FPOs as well — eighteen months for the minimum contribution and six months for the excess, measured from allotment in the FPO. The capital-expenditure carve-out preserving the three-year lock-in applies in the FPO context too, on the same logic that long-gestation project funding warrants a longer tie-in.
The regulations also exempt certain mature issuers from the minimum-contribution requirement in an FPO — broadly, where the issuer's equity shares have been listed on a stock exchange for at least three years and it has a satisfactory track record of compliance and dividend payment, or where there is no identifiable promoter. The premise is that a seasoned, widely held, well-governed company has an established market record that substitutes for the signalling function of a fresh promoter lock-in. Candidates should be careful to distinguish these FPO-specific reliefs from the IPO regime; the broader eligibility distinctions are developed in eligibility for FPO and eligibility for IPO.
What counts as a 'security': the Sahara backdrop
The entire lock-in machinery presupposes that the instrument being locked in is a “security” and that the issuance is a public issue within SEBI's regulatory reach. Both propositions were tested to their limit in Sahara India Real Estate Corporation Ltd. v. SEBI, reported at (2013) 1 SCC 1 and decided by the Supreme Court on 31 August 2012. Two Sahara group companies had raised tens of thousands of crores from millions of investors through optionally fully convertible debentures (OFCDs), characterising the exercise as a private placement outside SEBI's jurisdiction.
The Supreme Court rejected the gambit. It held that OFCDs are “securities” within the meaning of the securities laws and that an offer made to fifty or more persons is, in substance, a public issue attracting the public-issue regime regardless of the issuer's private-placement label. The Court affirmed SEBI's jurisdiction and directed refund of the collected sums with fifteen per cent interest. Sahara matters to this chapter because it polices the perimeter: a promoter cannot escape contribution, lock-in and disclosure obligations by dressing a public fund-raising as a private placement of an exotic instrument. The substance-over-form reasoning ensures that the protective scheme — including the lock-in restraints — cannot be circumvented by labelling, anchoring the regulatory premise on which the entire introduction and object of the ICDR framework rests.
Consequences of breach and ongoing monitoring
Non-compliance with the contribution and lock-in requirements is not a technical lapse to be cured at leisure. The minimum promoters' contribution must be brought in before the issue opens, and the merchant bankers' due-diligence certificate filed with SEBI must confirm compliance; an issue that does not meet the floor cannot proceed. Where promoters dispose of locked-in securities in breach of Regulations 16, 17 or 22, SEBI may exercise the full range of its remedial and penal powers, including directions to disgorge unlawful gains, debarment from accessing the securities market, and monetary penalty under the SEBI Act.
Because lock-in is recorded in the depository system, a breach is also operationally difficult: the depository flag or non-transferability marking should prevent the debit of locked securities in the ordinary course, so an attempted sale typically fails at the system level rather than after the fact. The continuing obligation to maintain the inscription, to honour the pledge conditions under Regulation 21, and to ensure that any permitted transfer under Regulation 22 carries the residual lock-in forward, means that compliance is monitored across the whole lock-in horizon, not merely at the moment of listing. For the aspirant, the safest mental model is a layered timeline anchored to the allotment date, with each layer — minimum contribution, promoter excess, and non-promoter pre-issue capital — releasing on its own schedule and each subject to its own narrow exceptions for pledge and transfer.
Frequently asked questions
What is the minimum promoters' contribution in an IPO and against what base is it measured?
Under Regulation 14 of the SEBI (ICDR) Regulations, 2018, promoters must collectively hold at least twenty per cent of the post-issue capital. The measure is the diluted post-listing share count, not the pre-issue holding. Where promoters fall short, the proviso allows specified investors such as AIFs, FVCIs, scheduled banks, public financial institutions, IRDAI-registered insurers, non-individual public shareholders holding at least five per cent, and promoter-group entities to make up the shortfall to a maximum of ten per cent without being branded promoters.
How long is the minimum promoters' contribution locked in after the 2021 amendment?
Following the SEBI (ICDR) (Third Amendment) Regulations, 2021, the minimum promoters' contribution is locked in for eighteen months from the date of allotment, reduced from the earlier three years. The three-year lock-in is retained only where more than fifty per cent of the fresh issue proceeds are proposed to be used for capital expenditure, on the logic that long-gestation project funding warrants a longer tie-in.
What is the lock-in on promoter holding above the twenty per cent and on shares held by others?
Promoter holding in excess of the minimum contribution is locked in for six months from allotment (reduced from one year). Under Regulation 17, the pre-issue capital held by persons other than promoters is generally locked in for six months from allotment as well, with exceptions for venture-capital and AIF holdings held for the prescribed period and for shares under approved employee benefit schemes.
Which securities cannot count toward the minimum promoters' contribution?
Regulation 15 disqualifies, among others, shares acquired in the preceding three years for non-cash consideration or through revaluation of assets, bonus shares issued out of revaluation reserves or unrealised profits, shares acquired by promoters in the one year before the DRHP at a price below the issue price (with the comparison price adjusted for bonus and splits), pledged securities, and securities on which the full subscription money has not been paid.
When may locked-in securities be pledged or transferred?
Regulation 21 permits a pledge of locked-in securities with a scheduled bank, public financial institution, systemically important NBFC or housing finance company, but only as collateral for a loan granted to the issuer to finance the objects of the issue, with the lock-in continuing on invocation. Regulation 22 permits inter-se transfer among promoters, to the promoter group or a new promoter, and transfers in connection with an open offer under the SAST Regulations, 2011, provided the residual lock-in continues in the transferee's hands.
How does the Sahara case relate to promoters' contribution and lock-in?
In Sahara India Real Estate Corporation Ltd. v. SEBI, (2013) 1 SCC 1, the Supreme Court held that optionally fully convertible debentures are securities and that an offer to fifty or more persons is a public issue within SEBI's jurisdiction, regardless of a private-placement label. The substance-over-form reasoning prevents promoters from circumventing contribution, lock-in and disclosure obligations by mislabelling a public fund-raising, thereby protecting the perimeter within which the lock-in scheme operates.
