Book building process establishes procedural framework for appointment, pricing, anchor allocation and allotment in public issues. Schedule XIII mandates that issuers using the book building process appoint lead manager(s) and, if applicable, syndicate members, enter underwriting and stock exchange agreements, use electronically linked bidding facilities and authorised bidding centres, and disclose issue size (but not price) in the red herring prospectus. Pricing is determined from bids with floor price/price band rules and disclosure timing; anchor investor allocations, lock-ins and eligibility are prescribed; allotment follows minimum subscription and proportionate allocation rules, and lead managers and intermediaries must maintain detailed records available for inspection.
