What is IPO Book Building?
Book building is a process used during an Initial Public Offering (IPO) to determine the price at which shares will be issued to the public. It involves collecting bids from investors at various price levels within a specified range, known as the price band. The final price is decided based on investor demand and is referred to as the issue price.
This method ensures transparency, efficiency, and optimal price discovery for the shares being issued.
How Book Building Works
- Price Band Announcement
- The company, along with the underwriters, decides a price band (e.g., ₹100–₹120 per share).
- Investors can bid for shares within this range.
- Bidding Period
- A specific time frame, usually 3–5 days, is allotted for investors to place bids.
- Investors must specify the number of shares and the price they are willing to pay within the price band.
- Demand Collection
- Based on the bids received, the underwriters gauge the demand for shares at different price levels.
- This data is compiled in a book, hence the name “book building.”
- Price Discovery
- The final price, called the cut-off price, is determined by analyzing where the demand is highest and ensuring the IPO is fully subscribed.
- Share Allotment
- Shares are allotted to investors at the cut-off price.
Types of Book Building IPOs
- 100% Book Building
- The entire issue price is discovered through the book-building process.
- In India, at least 75% of the shares must be allocated to Qualified Institutional Buyers (QIBs).
- 75% Book Building
- In this type, 75% of the issue undergoes the book-building process, while the remaining 25% is issued at a fixed price.
Advantages of Book Building
- Efficient Price Discovery
- Reflects true market demand, ensuring a fair issue price.
- Transparency
- Investors bid directly, and the process is regulated by authorities like SEBI in India.
- Flexibility for Investors
- Allows investors to bid at a price they deem fair.
- Optimal Capital Raising
- Helps companies maximize proceeds by offering shares at the best possible price.
Disadvantages of Book Building
- Complexity
- Requires a deeper understanding of pricing and market dynamics, which might deter retail investors.
- Uncertain Allotment
- Investors may not receive the desired number of shares if the issue is oversubscribed.
- Potential Price Manipulation
- There is a slight risk of collusion or speculative bids influencing the final price.
Key Terms in Book Building
- Price Band: The range within which investors can place their bids.
- Floor Price: The minimum price in the price band.
- Cap Price: The maximum price in the price band.
- Cut-Off Price: The final issue price determined through the book-building process.
- Oversubscription: When demand exceeds the number of shares offered, leading to proportionate allotment.
Book Building Example
Company: ABC Ltd.
Price Band: ₹100–₹120
Bidding Period: 3 days
- Investor A: Bids for 100 shares at ₹105.
- Investor B: Bids for 200 shares at ₹115.
- Investor C: Bids for 300 shares at ₹120.
Outcome:
- Based on demand, the cut-off price is decided at ₹115.
- Investors who bid at ₹115 or higher receive shares at ₹115.
Conclusion
Book building is a sophisticated and transparent method for determining the issue price of shares during an IPO. By aligning the interests of the company and investors, it ensures fair pricing and efficient allocation of shares.
