The Securities and Exchange Board of India (SEBI) has introduced significant changes to the Initial Public Offering (IPO) share-allocation rules, aimed at enhancing institutional participation in the Indian capital markets. These amendments, set to take effect from November 30, mark a substantial shift in the IPO landscape.
Key Changes in IPO Anchor Book Allocation
SEBI has made the following crucial modifications to the IPO anchor book allocation:
| Category | Previous Allocation | New Allocation |
|---|---|---|
| Total Anchor Investor Reservation | 33% | 40% |
| Mutual Funds | Not specified | 33% |
| Insurance Companies and Pension Funds | Not specified | 7% |
Reallocation Mechanism
In cases where the 7% reserved for insurance companies and pension funds remains unsubscribed, SEBI has implemented a reallocation mechanism. This unsubscribed portion will be redirected to mutual funds, ensuring maximum utilization of the anchor book.
Increase in Maximum Number of Anchor Investors
SEBI has also revised the maximum number of anchor investors allowed for IPOs with anchor portions exceeding Rs 250 crore:
| Anchor Portion | Previous Max Investors | New Max Investors |
|---|---|---|
| Per Rs 250 crore | 10 | 15 |
Allocation Rules for Smaller IPOs
For IPOs with anchor allocations up to Rs 250 crore, SEBI has set the following guidelines:
- Minimum number of investors: 5
- Maximum number of investors: 15
- Minimum allotment per investor: Rs 5 crore
Merger of Discretionary Allotment Categories
In a move to streamline the allocation process, SEBI has merged Category I and Category II discretionary allotments into a single category for allocations up to Rs 250 crore.
Implications for the Market
These amendments to the ICDR (Issue of Capital and Disclosure Requirements) norms are expected to have far-reaching effects on the Indian IPO market. By increasing the anchor book size and introducing specific allocations for different institutional investors, SEBI aims to:
- Enhance stability in IPO subscriptions
- Increase participation from long-term institutional investors
- Provide more confidence to retail investors
The changes reflect SEBI's ongoing efforts to refine and strengthen the Indian capital markets, making them more attractive to both domestic and international investors.
As these new rules come into effect, companies planning to go public will need to adjust their strategies to align with the revised allocation framework. Market participants will be keenly watching how these changes impact IPO subscriptions and post-listing performance in the coming months.
