HNI IPO Application Guide (NII Allotment Rules, Benefits & Funding)

Investing in IPOs can be a high-reward opportunity, especially for High Net-Worth Individuals (HNIs) who fall under the NII (Non-Institutional Investor) category. Any investor who wants to invest more than Rs 2 lakh in the mainboard IPO and bid for at least 3 lots in the SME IPO can submit an IPO bid under the NII category.

This article will provide a complete HNI IPO Guide explaining the step-by-step HNI IPO Application process, IPO allotment rules for HNIs, HNI IPO funding and practical tips for HNIs.

But before you jump in, let’s first understand who are HNI/NII investors are in IPO.

HNI (NII) in IPO Meaning

Investors who bid for IPO shares above Rs 2 lakh are considered as HNI or NII. However, in SME IPO, investors must bid for 3 lots (requires minimum investment above Rs 2 lakh) to submit IPO applications under the NII category.

HNI and NIIs are the same, as both fall under the NII investor category. Indian residents, NRIs, HUFs, companies, and Trusts can participate in IPO under the NII category.

In book-building mainboard and SME IPOs, atleast 15% of the issue size is reserved for NII quota. While in fixed-price issues, up to 50% shares are reserved for subscription by NIIs.


Types of NII Investors (Small and Big NII)

NIIs are further classified as; small NII (sNII) and big NII (bNII).

  • Small NII (Rs 2 lakh-10 lakh): HNI investors with IPO applications up to Rs 10 lakh are known as small NIIs. Out of 15% shares reserved for NIIs, 1/3rd shares are reserved for small NIIs
  • Big NII (More than Rs 10 lakh): HNIs who apply for shares worth more than Rs 10 lakh are called big NII. NII Quota has 2/3rd shares reserved for subscription by big NII.

HNI IPO Applications Process (Step-by-Step Guide)

HNIs can submit IPO applications via two methods:

  • Apply IPO via ASBA net banking process: Above Rs 5 Lakh
  • UPI process: HNI applications upto Rs 5 lakh.

Apply for IPO in NII category via UPI

HNI IPO applications up to Rs 5 lakh can be submitted through UPI.

  1. Log in to your broker’s trading account (Zerodha, Groww, Prostocks, Angel One, etc.)
  2. Go to the IPO option.
  3. Select the IPO you want to apply to.
  4. Enter IPO order details: Lot size, price, and select NII category.
  5. Enter your UPI ID (linked to your trading account).
  6. Submit IPO bid.
  7. Approve the UPI mandate request on the UPI app.
  8. Check IPO order book to track status.

Steps to apply for IPO in NII category via ASBA

ASBA (Applications Supported by Blocked Amount) is a facility provided by a bank to apply for IPOs. HNIs can apply for IPO using the ASBA process via their net banking portal.

  1. Log in to a net-banking website or app.
  2. Go to the IPO section.
  3. Select the IPO.
  4. Click on Apply IPO.
  5. Fill IPO application;
    1. Select NII as investor category.
    2. Enter lot size
    3. Price within the price band
    4. DP ID or Demat account number
  6. Submit IPO application.
  7. Click on the IPO order book to view your IPO application status.

HNIs must know before applying in IPO:

  • NIIs cannot apply at the cut-off price.
  • NIIs cannot cancel or withdraw their IPO bids.
  • NIIs can modify IPO bids to increase the application amount but cannot reduce it.
  • The cut-off time for HNI IPO application is 5:00 PM on the issue closure date. It means HNIs must accept the UPI mandate before 5:00 PM for a successful bid.

HNI IPO Allotment Rules

HNI IPO allotment is generally done on a proportionate basis. It means larger applications are allotted with bigger number of shares, if oversubscribed.

SEBI also introduced the lottery-based allotment to small NIIs for heavily oversubscribed IPOs. So, the allotment method may sometimes differ for big and small NIIs. The lottery-based allotment mechanism was introduced to give small NII bidders a chance of being allotted.

IPO Allotment for HNI: Small Vs Big NII

  • Small HNI (sHNI): (Upto Rs 10 Lakh): Proportionate allotment (if not heavily oversubscribed), lottery (if heavily oversubscribed).
  • Big HNI (bHNI) (More than Rs 10 lakh): Always proportionate for oversubscribed IPOs.

Allotment to NIIs in case of oversubscription

Proportionate Allotment: Allotment is calculated based on the number of shares applied relative to total NII applications.

When the company receives NII applications for a higher number of shares than shares available in the NII Quota, the allotment is done on a proportionate basis.Means each NII applicant will receive a pro-rata allotment based on their IPO bids.

HNI IPO Allotment ratio = (Shares reserved for NIIs/Total Shares Applied by NIIs)

Suppose a company has 10,00,000 shares reserved under NII Quota, and NIIs have bid for a total of 50,00,000 shares. Shares applied by an HNI is 1,00,000, so the pro-rata allotment will be for:

= (10,00,000/50,00,000)*1,00,000

= 20,000 shares

So the NII who applied for 1,00,000 shares, would receive 20,000 shares as proportionate allotment.

Lottery system: In certain cases, especially when the oversubscription under sNII (sHNI) is extremely high, and the allotment cannot be done proportionately due to logistical or regulatory reasons, the process may turn into a lottery system. This typically happens in the case of very high oversubscription.

Full allotment to NIIs in undersubscription or full subscription

Ifan IPO has 10,000 shares reserved under the NII quota, and the company has received an equal or lower number of bids from NII, each applicant will get full allotment for the shares they have applied for.


NII IPO Allotment Rules

  • One application per PAN is permitted – multiple applications under the same PAN will be rejected.
  • Allotment ratio may be different for small vs big NII.
  • HNI IPO Allotment is usually proportionate, but rarely lottery mechanism may apply for high oversubscription.
  • In case of undersubscription, all NII applicants will receive full allotment.
  • SEBI allows spillover between sNII and bNII. If sNII category is undersubscribed, the unsubscribed shares can be allotted to bNII.

HNI IPO Funding

HNI IPO funding means borrowing short-term loan to apply for IPO shares in the NII / HNI category, with the expectation of listing gains. These are usually 7-day loan offered by NBFCs, private financiers, or some banks.

How IPO funding for HNI investors work?

  • As an NII, you decides the application amount say 10 lakh, 50 lakh, etc.
  • You use the money available, and the balance amount is funded by financier. Generally, HNI IPO funding is provided for 80% - 90% of application amount.
  • Financier charges interest on the funded amount say 0.02% - 0.06% per annum.
  • On the IPO listing, shares are sold, and investor will repay the loan + interest. And remaining profit/loss goes into investor’s pocket.
  • Interest on HNI IPO funding is charged on daily basis.

HNI IPO Funding Cost Calculation – Example

HNI IPO Funding Cost = Loan Amount * Daily Interest rate * No. of funded days

  • HNI IPO Funding amount – 10 Lakh

  • Interest rate = 0.05% per day

  • Duration = 7 days

= 10,00,000*0.05%*7 days

= Rs 3,500

So, the funding cost is 3,500.

Refer our HNI IPO Funding Calculator for more details.


HNI IPO Benefits

Higher allotment chances for larger HNI applications.

  • Potential for quick listing gains – HNIs bid for larger amount so they can make higher absolute profits from good IPOs.
  • Many HNIs can access short-term IPO funding via brokers/NBFCs.
  • The funds remain in your bank account and continue earning saving bank interest.
  • HNIs can sell allocated IPO shares in the market on listing day. There is no lock-in period.
  • Unlike QIBs, HNIs do not need to be SEBI registered.
  • HNI NRI's are also eligible to apply in IPO similar to resident Indians.

HNI IPO Risks

  • bNII category may also heavily oversubscribed, so even large applications may also receive small proportional allotment.
  • Risk of huge listing loss on investment.
  • No guaranteed allotmentto NII, if the number of lots applied is less than the number of times the issue is oversubscribed in the NII category.
  • HNI investors cannot revise or withdraw the bid once placed.
  • Some companies offer a discount to retail, employee, and shareholders. These discounts are not available to HNI investors.
  • Most HNIs take IPO funding on interest. In case IPO doesn't get listed well, the investor may incur a huge loss.
  • HNI investors cannot bid on cut-off price.
  • The funds remain blocked in the bank account for 7 to 10 days. These funds can't be used for any other purposes.

Difference between HNI and Retail

Both High Net-worth Individuals (HNI) and Retail Individual Investors (RII) are individual people who apply for an IPO under two different reserved categories i.e. Retail and NII.

The Retail Portion is reserved for individuals who apply for not more than Rs 200,000 in an IPO. The HNI's are individuals who apply for more than Rs 200,000. The HNI bids are considered under the (Non-Institutional Investor) NII portion.

IPO HNI Vs Retail

 

Retail Investors

High net-worth individuals (HNI)/Non-Institutional Investors (NII)

Eligibility

Resident Indian individuals and NRIs applying for shares not exceed Rs 2 Lakh in mainboard IPO and applying for 2 lots in SME IPO.

Resident Indian individuals and NRIs applying for IPOs worth more than Rs 2 Lakh in mainboard IPO and applying for minimum 3 lots in SME IPO.

Shares Available

Not less than 35% of the Offer

Not less than 15% of the Offer.

Out of total NII reservation, 1/3rd is reserved for SNIIs and 2/3rd for big NIIs.

Basis of Allotment

Lottery.

A maximum number of bidders will be allotted 1 lot.

In the case of oversubscription, the chance of getting 1 lot is the same for an individual applied for one lot of Rs 15k or multiple lots up to Rs 2L.

Proportionate

But if you applied for fewer lots than the number of times issue oversubscribed, a lottery is drawn for one lot allotment. For example, if the IPO is subscribed 100 times in NII and an HNI applied for 90 lots, the allotment is done by lottery.

cut-off price

Allowed to invest at the cut-off price.

Not allowed to use the cut-off price option. HNIs have to specify the exact price at which they would like to buy the IPO shares.

Withdraw or lower the Bids

Retail investors are allowed to withdraw or lower the bids

HNIs are not allowed to withdraw or lower the bids. They can modify to increase the application amount.

Frequently Asked Questions

No, you cannot apply for both Retail and HNI categories for an IPO. The PAN number used in the application should be unique in an IPO. If you make two applications using the same PAN number, both applications will be rejected.

Note that if a retail investor applies for more than Rs 2 Lakhs of shares in an IPO, the bid is considered as an HNI bid in the (Non-Institutional Investors) NII category.

Yes, any resident individual or non-resident individual (NRI) can apply in the HNI category. The HNI category is also known as Non-Individual Investors or NII.

A retail IPO application of more than Rs 2 Lakh is considered an HNI application. The shares for this application are allocated under the (Non-Institutional Investors) NII category.

  2. Filling Paper Form (ASBA)

    You could visit the bank branch and apply in the paper form.

Investment in the HNI category of IPO is a high-risk investment. An investor should have an understanding of risks and rewards when investing in this category.

Risks in applying in HNI Category

  • Investing Borrowed Money

    Most HNIs take IPO funding loans to invest in IPO. There are a few risks with this:

    1. You have to pay interest on the loan.
    2. In case the share prices go down on listing, you may have to book losses quickly.
    3. You have to sell allocated shares as soon as possible to repay the loan.
    4. You have to calculate the cost of each share carefully along with the estimation of oversubscription.
  • 10 Days Until Listing

    The IPO shares start trading in the market in 7 to 10 days. A lot can happen in those days. In case the market turns adverse in 10 days, you may incur huge losses on the listing day.

  • Number of Shares Applied

    The shares in the NII category for HNIs are allotted by the lottery system if the number of lots applied is less than NII over-subscription. In this case, you may not get the allotment. Even if you get it, it will be just one lot.

    HNIs with cash of 10-50 lakhs in their savings bank could apply with their funds. In this case, the risk is low but the chances of allotment are minimal too. Good IPO subscribes 300 to 1000 times in the NII category.

  • Cancel or Modify Bid

    HNIs are not permitted to revise or cancel the bid once placed. Most HNI's apply at the last minute.

  • Cannot apply on Cut-off Price

    HNIs are not permitted to apply at the cut-off price. They have to place the bid at a fixed price in the give price band. The HNIs doesn't get any allotment if the bid price is less than the price fixed for the IPO shares.

HNIs take a calculated risk on IPO funding. They calculate and estimate how much subscriptions will be in the HNI category. They apply for 10 to 20 times higher lots than subscriptions with the funded amount.

Example:

  • NII oversubscription (Expected): 100 Times
  • Applied Quantity: 1000+ Lots
  • Lot Size: 15 Shares
  • Allotment (Confirm): 10 Lots (if 100x Subscribed)
  • Interest Cost: Rs 120 per share (breakeven Point)
  • Total Interest Cost: Rs 120 * 10 Lots * 15 Shares per lot = Rs 18,000
  • Listing Gain per Share (Estimated): Rs 150 per Share
  • Profit: Rs 150 * 10 Lots * 15 Shares per lot = Rs 22,500
  • Net Profit (Estimated) = Rs 22,500 - Rs 18,000 (Interest Cost) = 4,500

Note in the above calculation, HNI has to estimate:

This is one of the key factors in calculating the grey market premium (GMP) of IPO shares.

HNIs take short-term loans of a few crores to a few hundred crore rupees to apply in an IPO. These loans are issued by public and private sector banks, NBFC, and other financial institutions.

Most of these large-size loans come at around 7% to 8% per annum interest rate. They are issued for 7 days.

The interest rate on IPO funding varies by:

  1. By IPO
  2. A person who is taking IPO funding
  3. Financial institutions offering IPO funding

HNI is part of the NII investor category. The basis of allotment for HNI depends on the type of IPO issue and the subscription levels.

In case of a mainboard IPO, the basis of allotment for HNI is as given below:

  • In case of under subscription in NII category, all HNI investors will receive full allotment.
  • In case of oversubscription, each HNI/NII investor will be allotted at least one lot as applicable to the NII category, subject to availability of shares. If any shares remain after the minimum allotment, they will be allotted on a pro-rata basis.
  • Calculation methodology applied:
    • The maximum number of allottees (sNII and bNII) to whom NII allotment can be made is determined.
    • Based on the number of applications received per category, the pro rata number of maximum allottees per category is determined.
    • The number of allottees per category determined in this way is then allocated a minimum number of shares in a lottery.
    • Remaining shares, if any, will then be distributed to the maximum number of allottees selected above.

 

Note:

  • In a mainboard IPO, there are small NIIs (sNIIs) and Big NIIs (bNIIs). The allotment method for sNII and bNII is the same.
  • Even though the minimum bid amount for bNII is equivalent to Rs. 10 lakhs and above. In case of oversubscription, bNII will be allotted shares worth Rs. 2 lakhs. (i.e. the minimum NII bid lot).

In an SME IPO, allotment to HNI/NII is done on pro-rata basis such that each allotted NII gets a minimum bid lot. In an SME IPO, there is no sNII or bNII.

Further details and examples can be found under Basis of Allocation.

Splitting the funds into two HNI IPO applications in an IPO does increase the chance of getting 2 lots but it also increases the chance of getting 0 lots. You could choose this strategy if you like the higher chance of getting 1 lot rather than increased chances of getting 2 lots.

Below is a calculation posted by our IPO forum member IPOLogic to support the above view:

Example 1

  1. You split the money in 2 accounts with 60 lots each. So, individual oversubscription factor = 60/100 = 0.6
    Chances of getting 0 lot: = (1-0.6) * (1-0.6) = 0.16 = 16%
    ii. Chances of getting 1 lot: = (0.6) * (1-0.6) + (1 - 0.6) * (0.6) = 0.48 = 48%
    iii Chances of getting 2 lot: = (0.6) * (0.6) = 0.36 = 36%
    iv Chances of getting at least 1 lot = 1 - 16% = 84%
  2. You don't split the money. So, individual oversubscription factor = 120/100 = 1.2 lot
    You will 100% chance of getting 1.2 lot
    ii chances of getting at least 1 lot = 100%

Example 2

  1. You split the money in 2 accounts with 15 lots each. So, individual oversubscription factor = 15/100 = 0.15
    chances of getting 0 lot: = (1-0.15) * (1-0.15) = 0.7225 = 72.25%
    ii. chances of getting 1 lot: = (0.15) * (1-0.15) + (1 - 0.15) * (0.15) = 0.255 = 25.50%
    iii chances of getting 2 lot: = (0.15) * (0.15) = 0.0225 = 2.25%
    iv chances of getting at least 1 lot = 1 - 72.25% = 27.75%

You don't split the money. So, individual oversubscription factor = 30/100 = 0.3 lot
i. chances of getting 0 lot: = (1 - 0.30) = 70 %
ii. chances of getting 1 lot: = 0.30 = 30%
iii chances of getting 2 lot: = 0%
iv chances of getting at least 1 lot = 1 - 70% = 30%

So, if you want some chance to have 2 lots, then it increases your chance of getting 0 lots.

Thus, it will decrease the chance of getting at least 1 lot too.

To get a confirmed allotment in the HNI category, you need to apply for more lots than the final issue over-subscription figure. But the challenge is, to do this; you will have to guess how many times the IPO will oversubscribe in NII (HNI) Category.

The IPO allotment in the Non-Institutional Investors (NII) category for HNIs is done either on a proportionate basis or lottery system. The allotment process is based on the number of lots applied and over-subscription in the NII category.

Let's understand this using three scenarios. Assume an IPO oversubscribed 100 times.

  • If you have applied for 100 lots, you get a confirmed allotment of 1 lot.
  • If you have applied for more than 100 lots, you get a proportionate allotment over the confirmed one lot.
  • If you have applied for lesser than 100 lots, the allotment is done based on the lottery system and thus is not guaranteed.

The HNI IPO allotment calculator can help you derive the number of shares/lots to be applied for, to get confirmed allotment based on the estimated oversubscription figure.

It's not easy to predict the subscription level of an IPO. The subscription level depends on factors like the issuer company fundaments, issue size, issue prices, grey market premium and market conditions.

Some analysts guess IPO over-subscription levels before IPO closes to estimate the HNI IPO Shares cost. But their prediction keeps changing until the last minute.

Most good IPOs get heavily over-subscribed in the range of 300 to 1000 times under the NII category (HNI) and 15 to 30 times in the retail category by application.

The oversubscription also depends on the demand in the grey market. The higher the demand for an IPO in the grey market, the higher are the chances of it getting oversubscribed.

It is difficult to derive the expected over-subscription of an IPO based on the historic data as there are too many variables to it.
