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.
