SEBI's rules do not use the term HNI. They define a **non-institutional investor (NII)** as anyone who is not a QIB, a retail investor or an eligible employee or shareholder bidding in a reserved portion, and who bids for **more than INR 2 lakh**. In this RHP, that typically includes resident individuals, eligible NRIs, HUFs, companies, trusts, societies, family offices and some foreign portfolio investors. The NII portion is split into two sub-categories: | Sub-category | Common name | Bid size | Share of the NII portion | |---|---|---|---| | Small NII (sNII) | HNI, "small HNI" | More than INR 2 lakh, up to INR 10 lakh | One-third | | Big NII (bNII) | "UHNI", "big HNI" | More than INR 10 lakh | Two-thirds | "UHNI quota" is market slang, not a separate category. There is no third NII bucket in a standard RHP. ## Bombay Coated IPO NII quota size The RHP says **not less than 15% of the net issue** goes to NIIs. Illustrative share counts use ~15% of BSE's **Issue Size - No. of Shares (2,34,68,846)** for BCSSL. Prefer RHP / exchange parameters when official post-anchor category counts publish. Share counts (fill from NSE/BSE post-anchor parameters when published), at the INR 82 cap: | | Shares (official) | Value at INR 82 (our calculation) | |---|---|---| | NII portion (15% of the net issue) | 35,20,327 | about INR 28.87 crore | | Small NII (one-third) | 11,73,442 | about INR 9.62 crore | | Big NII (two-thirds) | 23,46,885 | about INR 19.24 crore | ## Minimum and maximum application amounts At the INR 82 cap and the 182-share lot: | | Lots | Shares | Amount | |---|---|---|---| | Small NII minimum | 14 | 2,548 | INR 2,08,936 | | Small NII maximum | 67 | 12,194 | INR 9,99,908 | | Big NII minimum | 68 | 12,376 | INR 10,14,832 | | Big NII maximum | Up to the NII portion | | Subject to investor limits | NIIs cannot bid at the cut-off price. You must bid at a specific price within the band, and your bid amount must clear the threshold at that price.
- **Minimum bid** to be in big NII: more than INR 10 lakh, so **68 lots (12,376 shares, INR 10,14,832)** if you bid at INR 82. - **Minimum allotment** in big NII: usually **14 lots (2,548 shares)**, the same as small NII -- confirm in this issue's basis of allotment. - So a big NII winner in an oversubscribed lottery often gets the **minimum NII block, not the full big-NII minimum bid**.
## How allotment works for small and big NII The RHP applies SEBI's rule for NII allotment (Schedule XIII of the ICDR Regulations): 1. **Each successful NII gets at least the minimum NII application size**, subject to availability. 2. **If there are not enough shares for every applicant to get that minimum, applicants are picked by a draw of lots**, as SEBI's rules provide. This applies in each sub-category separately. 3. **Any shares left after the minimum allotments** are allotted proportionately. Bigger bids do not buy a bigger minimum. They only matter if the category is not heavily oversubscribed. ## Paying for an NII bid - **UPI works only up to INR 5 lakh.** Larger NII bids must use ASBA. - **You cannot withdraw or lower your bid.** QIBs and NIIs can only revise upwards under typical RHP rules. - **The full amount is blocked** until allotment.
