In simple words, the book running lead manager helps the company bring its shares to market in an orderly way. The role connects the issuer, investors, regulators, and other intermediaries throughout the issue process.
Stage-by-Stage Responsibilities of the BRLM
The BRLM’s work begins well before the IPO opens and continues beyond the listing date. The table below maps each IPO stage to the BRLM’s specific responsibilities.
| IPO Stage | BRLM Responsibility | Who Executes |
|---|---|---|
| Pre-Filing | Due diligence on the issuer’s financials, business model, and legal history | Merchant Banker (BRLM) |
| Pre-Filing | Drafting and filing the Draft Red Herring Prospectus (DRHP) with SEBI | BRLM + Legal Counsel |
| Pre-Filing | Appointing intermediaries: registrar, bankers, escrow agents, syndicate members | BRLM |
| SEBI Review | Responding to SEBI observations and incorporating changes into the prospectus | BRLM + Legal Counsel |
| Pre-IPO Marketing | Conducting the roadshow and Anchor Investor allocation (1 day before IPO opens) | BRLM |
| IPO Open Period | Running the book-building process; collecting bids via stock exchange platform | BRLM + Syndicate Banks |
| IPO Open Period | Monitoring subscription levels across categories (QIB, NII, RII) in real time | BRLM |
| Post-Close | Finalising the issue price (cut-off price) based on demand at each price level | BRLM + Issuer |
| Post-Close | Coordinating allotment with the registrar; managing oversubscription and refunds | BRLM + Registrar |
| Listing | Coordinating with stock exchanges (NSE/BSE) for listing approval and trading start | BRLM + Exchange |
| Post-Listing | Stabilisation (if green shoe option exists): undertaking permitted price stabilization activities in accordance with applicable regulations, where a green shoe option is available. | Stabilising Agent (BRLM) |
Book Building and Price Discovery — How It Works
Book building is the process by which the BRLM collects bids from investors across a price band to determine the final issue price (cut-off price). It is a demand-aggregation mechanism, not a guaranteed price-setting tool.
SEBI mandates that the cap price cannot exceed 120% of the floor price. For example, a floor of Rs. 490 allows a cap of at most Rs. 588. Investors can bid at any price within the band or at ‘cut-off,’ which means they accept whatever price is finally determined.
Hypothetical Book Building Demand Schedule (Issue Size: 2.5 crore shares)
| Bid Price | Bids at This Price | Cumulative Bids | Subscription | Status |
|---|---|---|---|---|
| Rs. 490 | 12,00,000 | 12,00,000 | 0.48x | Below cut-off |
| Rs. 495 | 28,00,000 | 40,00,000 | 1.60x | Below cut-off |
| Rs. 500 | 45,00,000 | 85,00,000 | 3.40x | CUT-OFF PRICE |
| Rs. 505 | 30,00,000 | 1,15,00,000 | 4.60x | Above cut-off |
| Rs. 510 | 18,00,000 | 1,33,00,000 | 5.32x | Above cut-off |
Reading the table: The cut-off price of Rs. 500 is the lowest price at which the cumulative demand (8.5 crore bids) meets or exceeds the issue size (2.5 crore shares), achieving 3.4x subscription. Eligible applicants who bid at or above the final issue price may be considered for allotment, subject to applicable allotment rules and oversubscription levels.
Why it Matters in an IPO?
The BRLM plays a central role because an IPO is not just a share of sale; it is a structured market event. The manager helps ensure that documents, pricing, marketing, and distribution are handled properly.
