Lock-In: Who Cannot Sell, and For How Long

A lock-in is a restriction that stops defined holders from transferring their securities for a defined period after an issue. The restriction attaches to categories of holder rather than to named people, it is recorded against the holding in the depository system, and it ends by the passage of time rather than by anybody's decision. Which categories are locked in, and for how long, are set in the Securities and Exchange Board of India (SEBI) requirements at sebi.gov.in.

The shape of the idea is not a finance shape at all, so something ordinary makes the better starting point. Suppose a neighbour is told that a scooter will not be sold until the monsoon is over. The neighbour has been given a promise. A promise rests entirely on the owner, it can be broken on any morning the owner feels like breaking it, and if it is broken the neighbour finds out afterwards, when the scooter has already gone. Now change one thing. Suppose the office that records who holds that scooter simply will not accept a transfer of it before a particular date. The owner's intentions have not changed at all. The change is that those intentions no longer matter to anybody.

The second arrangement is what a lock-in is, and nearly everything that goes wrong in thinking about lock-in comes from quietly assuming it is the first. People picture a signed sheet of paper in a file somewhere, a sentence beginning with the words the undersigned hereby undertakes, and somebody in an office checking it if a sale is ever noticed. The signed-undertaking picture produces the wrong expectations at every turn: it makes the restriction look breakable, it makes enforcement look like an investigation, and it makes the end of the restriction look like a decision somebody takes. None of that is how a lock-in works, and the difference is not a technicality. The difference is the whole design.

One case runs through this guide. Vindhya Ceramics Private Limited, invented for this illustration, raised Rs 40,00,00,000 through a public issue: Rs 25,00,00,000 in equity and Rs 15,00,00,000 in debentures. The book discovered a price of Rs 100 per share, so the equity portion is 25,00,000 shares. Of that equity portion, 7,50,000 shares worth Rs 7,50,00,000 went to 4 anchor investors before the issue opened. Another 14,50,000 shares worth Rs 14,50,00,000 went to public applicants. Suravali Registry Services Private Limited processed 12,400 applications and rejected 340 on verification, so 12,060 applicants came onto the register of holders. The remaining 3,00,000 shares worth Rs 3,00,00,000 were taken up by Trilokpur Capital Markets Private Limited inside its underwriting commitment of Rs 6,00,00,000. The three parts come to 25,00,000 shares and Rs 25,00,00,000 exactly. Ratnakar Deshpande is the finance director and Prerna Wadekar is the company secretary.

Lock-in in India is set by the securities regulator, and the length of time that applies to each category of holder is read from the requirement that sets it rather than remembered. The mechanism below is the same whichever category is in question: what a lock-in is, the kinds of holder it reaches, why it exists, how it is enforced, what a locked holder can still do, what happens at the end, and how the current period for any category is read in a few minutes from the source that sets it.

What is a lock-in, stated precisely?

A lock-in is a restriction on transferMoving securities from one holder to another, so that the second holder replaces the first in the records. Transfer is the single act a lock-in prevents.. For a stated period, securities held by a stated kind of holder cannot be moved out of that holder's account into anybody else's. The restriction has no other content. A lock-in is not a restriction on holding, it is not a restriction on the rights the securities carry, and it is not a statement by anybody about what the securities are worth. Strip it down to one line and a lock-in says: this holding stays where it is until a date, and after that date it does not have to.

Notice how narrow that is. The narrowness is what makes the mechanism possible. A restriction on intentions would need somebody to look inside a person. A restriction on value would need somebody to have a view. A restriction on transfer needs only one thing: a system that knows which holdings are restricted and refuses to move them. Lock-in is written the way it is because transfer is the one thing about a holding that a record keeper can see and stop. Everything else about a holder happens out of view.

What does a lock-in actually prevent?

Which categories of holder does a lock-in reach?

A lock-in is never written against a person. A lock-in is written against a category of holderThe class a holder falls into under the requirements, decided by how they came to hold and what their relationship to the issuer is, rather than by who they are., and any particular holder is restricted or not restricted according to which category their holding falls into. A category rule is closer to a railway quota than to a personal undertaking. A quota rule applies to the class of ticket booked, not to the passenger's name, and two passengers sitting in the same coach can be under different rules because they came in through different doors. Holders after an issue are exactly like that.

The kinds of holder the requirements sort people into are recognisable. There is the holding a promoterA person or entity treated by the requirements as being behind the company, with control or a founding role, rather than as an ordinary outside investor. contributes into the issue itself. There is the rest of a promoter's holding, the part that was not contributed. There is capital held before the issue opened by people who are not promoters at all. There are shares allotted to anchor investors ahead of the offer. There are shares that came out of a preferential issue, shares held under an employee scheme, and shares that arrived by conversion of something else. Each of those is a category, each is defined in the requirements, and the definitive list of them, along with what applies to each, is set at sebi.gov.in and read there rather than remembered.

The first question about anybody's position after an issue is therefore never how much do they hold, and never who are they, but which category is this holding in. Get the category wrong and every answer after it is wrong, however carefully the rest of the work is done. Get the category right and the remaining question has exactly one place to be answered.

A rule about names would need rewriting; a rule about categories does not IF IT WERE WRITTEN AGAINST NAMES holder one, by name, is restricted holder two, by name, is restricted holder three, by name, is restricted holder four, by name, is restricted and a new line for every new holder minus: the rule is never finished AS IT IS WRITTEN, AGAINST CATEGORIES holder one holder two holder three holder four ONE CATEGORY the rule is written here a new holder simply sorts into one plus: the rule never needs a name So the first question about any holding after an issue is which category it falls into, and never who is holding it or how much of it they have.
Because the restriction is written against categories rather than against people, sorting a holding into its category is the step that has to come first, and no amount of knowing who the holder is can replace it.

Somebody asks whether a particular holder in a newly listed company is locked in. What is the first thing to establish?

Why does a lock-in exist at all?

Underneath the machinery there is a plain commitment problem, and once it is stated the categories stop looking arbitrary. People who were inside a company before the public arrived know things the public does not, and they hold securities that were acquired on terms the public never had access to. When an issue brings in outside money and creates demand where there was none, those insiders are in a position to sell into demand that their own issue manufactured. Nobody has to be dishonest for that to be a problem. The possibility alone is enough to make the offer worth less to the people being offered it.

One answer to that problem is an undertakingA written promise given by one party to another. An undertaking binds intentions, so it can be broken, and the breach is normally discovered only after the act it was meant to prevent.: get the insiders to promise not to sell. The undertaking has a defect that no amount of drafting removes. A promise is only as good as the person giving it and the enforcement behind it, both of which are unknowable to the reader deciding whether to apply. The other answer is to remove the ability. Lock-in converts a promise about intentions into a fact about capability, and a fact about capability needs nobody to be trusted. For the period nobody is able, so nobody has to be believed.

Two ways to stop a sale, and only one of them works without trust WAY ONE: AN UNDERTAKING NOT TO SELL minus: it needs somebody to be trusted, and the reader cannot check that minus: it can be broken on any morning, by anybody who decides to break it minus: the breach is found afterwards, when the securities have already moved WAY TWO: AN INABILITY TO SELL, WHICH IS LOCK-IN plus: it needs nobody to be trusted, so there is nothing for a reader to check plus: it cannot be broken, because the instruction is simply not carried out plus: nothing has to be found out, because nothing happened in the first place Lock-in is the second kind, and that is the whole design of it: it changes the question from what somebody intends to what somebody is able to do.
An undertaking asks a reader to judge a person, while a lock-in removes the need to judge anybody at all, and that swap from intention to capability is the reason the restriction is built the way it is.

How is a lock-in actually enforced?

Breaking Into Quants Bootcamp — Fin Maverick

How is a lock-in enforced when the holding is only an electronic record?

Here is the part almost nobody expects, and it is worth slowing down for. A lock-in on securities held in electronic form is not a paragraph in a document that somebody consults. The restriction is a flag against the holdingA marker recorded against the securities themselves in the depository system, so that the status travels with the holding rather than sitting in a document about it. inside the depository system. The holding sits in an account with the usual fields, and one of those fields records that this quantity of this security in this account is restricted. The status is a property of the holding, not a statement about the holder.

The consequence of keeping the restriction inside the record is the whole point. When an instruction to transfer arrives, the system reads that field before it does anything else, and where the field says restricted, the instruction is not executed. A locked holding cannot be transferred because the system will not transfer it, and a restriction of that kind is nothing like an undertaking. There is nothing to investigate, so there is no investigation. Nobody is asked, so there is no discretion. The securities never moved, so there is no window in which they have moved and somebody is deciding what to do about it. The refusal happens as the instruction arrives, in a fraction of a second, and the holder is told what everybody in the chain already knew.

Keeping the restriction in a field is also why nobody sensible relies on memory. In the Vindhya Ceramics Private Limited issue, the shares allotted to the 4 anchor investors and the shares held before the issue opened sat in accounts with exactly the same fields as the shares allotted to the 12,060 public holders. Nothing about the accounts looks different from the outside. The status field is where the difference lives, and reading it takes a moment while guessing at it takes a career.

A lock-in is a field in a record, not a paragraph in a document THE HOLDING, AS THE SYSTEM HOLDS IT account one holder security one equity share quantity as allotted status RESTRICTED 1. AN INSTRUCTION TO TRANSFER ARRIVES from the holder, in the ordinary way 2. THE SYSTEM READS THE STATUS FIELD before anything else happens 3. THE INSTRUCTION IS NOT EXECUTED no discretion, no enquiry, no delay Nobody has to notice anything, and nobody has to be honest about anything. The refusal happens inside the system, before the securities could have moved at all.
The restriction lives in a status field on the holding itself, so an instruction to transfer is stopped at the moment it arrives rather than investigated after the securities have gone.

What can a locked holder still do, and what is the one thing removed?

A locked holder is a full holder in every respect but one. The securities remain theirs. The rights attached to those securities remain attached and can be exercised. Whatever is distributed on the securities reaches them in the ordinary way. Their name stays on the register of holders, they are counted where holders are counted, and the position shows in their account exactly as any other position does, with one field reading differently. Subtract the ability to hand the holding to somebody else, and nothing else has been subtracted.

The distinction matters because the commonest overcorrection is to treat a locked holder as somehow suspended, as though the securities had been taken into custody and handed back later. The securities never went anywhere. The restriction concerns transfer alone, so a locked holder is a complete holder who simply cannot pass the holding on. Prerna Wadekar, as company secretary of Vindhya Ceramics Private Limited, deals with restricted holders in exactly the way she deals with unrestricted ones for every purpose except one, and treating them as a lesser class of holder would be a straightforward error of administration.

Five things kept, one thing removed WHAT THE HOLDER STILL HAS plus: the securities are still the holder's plus: the rights attached to them plus: whatever is distributed on them plus: the place on the register of holders plus: the position, visible in the account WHAT IS REMOVED minus: handing the holding to anybody NOTHING ELSE this space is empty on purpose, and counting the rows is the whole comparison A locked holder is a complete holder with one ability taken away, so treating them as a suspended or lesser holder is an error of administration.
Counting the rows on each side settles the point: five ordinary attributes of a holding survive a lock-in untouched, and only the ability to pass the holding on is taken away.

Which of these can a holder whose securities are locked in still do?

What happens when the period ends?

Nothing dramatic, and that is the finding. The restriction ends by expiryThe end of a period by the passage of time alone, without any application, approval or act by anybody.. Nobody applies for anything, nobody grants anything, nobody signs anything and no discretion is exercised anywhere. The period runs out, the status field stops saying restricted, and a holding that could not be transferred yesterday can be transferred today. The mechanism that refused the instruction is the same mechanism that now accepts it, and it did not change its mind about anything.

The consequence is easy to miss and is the useful part. Because nobody decides when a lock-in ends, the end is knowable in advance by anybody who knows the category and has read the current requirement. Compare that with anything that depends on a decision. A decision has to be waited for, guessed at, or extracted from somebody. An expiry has to be calculated, and the calculation is available to everybody who bothers. A knowable ending is a rare property in regulation and it is worth naming.

The restriction ends by itself, and no length is drawn here on purpose THE MOMENT IT ENDS RESTRICTED: CANNOT BE TRANSFERRED FREE TO TRANSFER this axis carries no scale, and the length is set in the current requirement WHO HAS TO ACT AT THAT MOMENT the holder nothing the issuer nothing the registrar nothing the regulator nothing WHY THAT IS THE USEFUL PART A decision has to be waited for or guessed at. An expiry only has to be calculated, and the calculation is open to anybody who knows the category and reads the current requirement.
Every party listed has nothing to do at the moment a restriction ends, and it is precisely that absence of any decision which makes the ending calculable in advance by anybody.

What came out of the Vindhya Ceramics issue restricted?

Take the Vindhya Ceramics Private Limited equity portion apart and the categories stop being abstract. Rs 25,00,00,000 was raised in equity at a discovered price of Rs 100 per share, giving 25,00,000 shares, and those shares reached three different kinds of holder by three different routes.

How the holding aroseAmount, inventedSharesWhere the answer for it is read
Allotted to 4 anchor investors before the issue openedRs 7,50,00,0007,50,000SEBI issue and disclosure requirements, sebi.gov.in

Read the last two columns together rather than across the rows. The arithmetic ties: Rs 7,50,00,000 and Rs 14,50,00,000 and Rs 3,00,00,000 come to Rs 25,00,00,000, and 7,50,000 and 14,50,000 and 3,00,000 shares come to 25,00,000 shares. No length of time appears anywhere in the table, and the last row says so. A category map with no period list is exactly the shape of file worth keeping. The holdings that existed before the issue opened, including whatever the promoters of Vindhya Ceramics Private Limited held, sit outside the issue arithmetic entirely and are sorted into their own categories in the same way.

The failure: reading a locked holding as a vote of confidence

The mistake that costs somebody something is made by careful people. A newly listed company is examined, the register is looked at, and the people who built the company are still holding their shares. An unsold founding holding reads immediately as belief. The founders know the business better than anybody and have not sold a single share, so they must think it is worth holding. The chain feels airtight and it has a hole in the first link.

The wrong reading is that a locked holding is a voluntary holdingA position held because the holder chose to keep it, when selling it was available to them., when in fact a locked holding is a compelled holdingA position held because it could not be sold, so the holder never expressed any preference about it at all. and tells nothing about whether the holder wanted to sell. The locked holder could not have sold. Because no choice was available, no preference was expressed. From the outside the two situations produce identical records, identical registers and identical position statements. Nothing in the observation distinguishes the two, and that is precisely why the mistake is so easy.

Think of somebody still sitting at a wedding at midnight. One of them is there because they are enjoying themselves. The other is there because their lift left without them. Photograph the hall and both are simply people who stayed. The cost falls on whoever draws a conclusion about conviction from an absence of choice, and the cost is delayed. The inference does not collapse gradually. The inference collapses on one specific day: the day the restriction ends and the holder has a real choice for the first time. Whatever happens after that day is information. Everything before it was the system, not the person.

Two records that read the same, and only one of them was a choice HOLDING ONE the holder chose to keep it same security same quantity STILL HELD on the register HOLDING TWO it could not have been sold same security same quantity STILL HELD on the register BOTH READ AS CONVICTION and one of them never said anything WHERE THE INFERENCE COLLAPSES Not gradually, and not on a day anybody chooses. It collapses on the one day the restriction ends and the second holder has a real choice for the first time. Everything observed before that day was the system working, and not a person deciding anything.
Both rows carry the same three words on the register, so an inference about conviction drawn from either one is really an inference drawn from an absence of choice.

Why is a lock-in period read from the requirement rather than written down?

Every lock-in period, for every category, is a figure set in the SEBI requirements. Lock-in periods have moved before, and the mechanism for moving them is ordinary and continuous. Nothing about a printed number decays visibly, so a period printed in a reference would look exactly as confident on the day after it changed as on the day it was written. And a lock-in period is not an idle fact. A lock-in period is precisely the figure somebody plans around: a date circled in a diary, a note made for a client, a line in a model. Taking it from a text that cannot update itself is how a stale figure ends up carrying a decision.

Consider the household version of the same problem, at a smaller scale. A person writes a subsidy amount on a card in their purse and answers questions from it for two years. The card holder is fast and confident and eventually wrong, and nobody sends a notice when a scheme changes. The person who instead wrote down which department publishes the scheme takes fifteen minutes to answer and is right every time, including next year. A file naming the category, the requirement it comes from and the date somebody read it survives any change to any period, and a file of periods does not.

Ratnakar Deshpande keeps exactly that file at Vindhya Ceramics Private Limited. Three columns and no fourth: the category, the requirement that names the category, and the date on which somebody last opened that requirement and read it. The file looks incomplete on the day it is written, and everybody raises that objection. The incomplete-looking file is the one still usable when somebody picks it up much later. The column that would make it look finished is the column that would quietly make it wrong.

The file that is kept, and the column that is deliberately not in it CATEGORY OF HOLDER REQUIREMENT DATE READ the promoters' contribution into the issue SEBI, sebi.gov.in 18 August the rest of the promoters' holding SEBI, sebi.gov.in 18 August capital held before the issue, by others SEBI, sebi.gov.in 18 August shares allotted to the 4 anchor investors SEBI, sebi.gov.in 18 August THE PERIOD COLUMN NOT RECORDED HERE A column of lengths looks like the finished version on the day it is written. It then goes quietly wrong at a moment nobody in the office can identify afterwards. Nothing in the file changes appearance when it does. A file of categories, requirements and dates read survives a change to any period. A file of periods does not, and gives no sign at all of the day it stopped being right.
Three recorded columns and one refused column together make a note that is still usable long afterwards, because what was written down is the route to the figure rather than the figure itself.

Why is a lock-in period read from the requirement each time rather than written down?

How is the current period for any category read?

Four steps, and they are the same four whatever the category is. First, the analyst names the category the holding falls into, using how it arose and who is holding it rather than what it is worth. Second, the analyst finds the requirement that names that category. For lock-in after an issue, that requirement is the SEBI issue and disclosure requirements. Third, the analyst opens the current text of that requirement at sebi.gov.in and takes the figure from the version in force rather than from a summary of it. Fourth, the analyst writes down the date on which it was read, in the same note as the answer.

The fourth step is the one people skip and the one that decides whether the note is worth anything a year later. A note without a date looks exactly as authoritative when it is badly stale as when it was made an hour ago, and the next person to pick it up has no way at all to tell the difference. So they either trust it and risk being wrong, or redo the whole search and the note has saved nobody anything. Ten seconds of writing is what separates those two outcomes.

Four steps, ending at the text that actually sets the figure 1. NAME THE CATEGORY from how the holding arose, not its size 2. FIND THE REQUIREMENT the instrument that names that category 3. OPEN THE CURRENT TEXT at sebi.gov.in, the version in force 4. WRITE DOWN THE DATE READ so the next reader knows how old it is the step people skip The procedure ends at a primary text and at a date, never at a summary, because two summaries agreeing shows only that one of them copied the other.
Naming the category, locating the requirement, opening the text in force and dating what was read is a short procedure whose final stop is the regulator's own wording, never anybody else's account of it.

What is the last step in looking up the current period for a category?

The India rulebook: which instrument sets what

All of this is Indian law and the instruments have names. Which categories of holder are subject to a lock-in after an issue, and the period that applies to each of them, sit in the SEBI issue of capital and disclosure requirements together with the circulars issued under them, at sebi.gov.in. The continuing obligations that a company carries once it is listed, of which restrictions on named holders form one part, sit in the SEBI listing obligations and disclosure requirements, also at sebi.gov.in. Where company law reaches an issue, the instruments sit with the Ministry of Corporate Affairs at mca.gov.in. How a restriction is recorded against a holding, and what the account then shows, is an operational matter handled by the depositories at nsdl.co.in and cdslindia.com. The depositories record a restriction rather than set it. The instrument is opened on the day the answer matters, the period taken from the version in force, and the document it came from noted beside the date of reading.

How does an analyst, a lender or a household actually use this?

Three different people put this to work in three different ways, and none of them needs to remember a single number to do it. An equity analyst looking at a recently listed company sorts the register of holders into categories before drawing any conclusion from it, and marks which holdings are restricted. The marking does not buy a view. The marking draws a boundary around what the register can support. Because the restricted holdings were never a decision, they are removed from the evidence entirely, and only the unrestricted holdings are left carrying any information about anybody's preference.

A lender taking listed shares as security asks a blunter question, and it is the question the whole mechanism answers. Security that cannot be moved is not security, so the first thing to establish is whether the holding can be transferred at all. Because the restriction lives in the status field rather than in somebody's promise, the lender checks a record instead of assessing a person, and the answer arrives with no judgement attached to it. A locked holding is not weak security, it is unusable security for the period, and the two are worth distinguishing.

A household with shares allotted under an employee scheme reaches the same place from the other side. The question is not what the shares are worth. The category the holding falls into decides whether the holding can be sold at all on any given day, so the category is the question. In all three cases the useful skill is identical: sort the holding into its category, then read the current period from the requirement that names that category, and never from memory. Whether any of those three ought to buy or sell is a different question entirely, and a lock-in has nothing to say about it.

What is a lock-in not?

Two things, and both mistakes push a reader in a direction with real consequences. A lock-in is not a bar on holding. The securities belong to the holder throughout, the rights attached to them are exercisable throughout, and the restriction concerns transfer alone. Reading it as a suspension of the holding leads to treating restricted holders as second class in registers, in counting and in correspondence, all of which is simply wrong.

A lock-in is also not a statement about value. Nobody assessed the securities and concluded they should be held. The restriction was applied because of how the holding arose and who is holding it, and it would have been applied identically whatever anybody thought the securities were worth. Reading it as an endorsement is the failure set out above, wearing a more respectable coat. And a lock-in is not a signal about what will happen at the end of it either. Whatever a holder does once the choice becomes available is a market question and a separate subject.

Boundaries. Every lock-in period can change, so every lock-in period, for every category of holder, sits in the requirements named below and is read there on the day it matters. Whether any holder should do anything when a restriction ends is a market question. How prices behave around the end of a restriction is a separate subject. The restriction that attaches specifically to anchor investors is set out under anchor investor. Shares, transfers and allotments are assumed rather than explained, and how a depository records a holding is set out under dematerialisation. How an issue is structured, negotiated, valued or timed as a commercial transaction is taught elsewhere entirely.

Measuring Risk in a Portfolio teaches you to compute and interpret the standard portfolio risk measures and say what each one misses.
