Investors widely use the Book Building Issue method in the stock market to determine the best price for an IPO (Initial Public Offering) through a demand-driven process. In this method, the issuing company and underwriters assess investor interest by allowing them to place bids within a predefined price range. Book building is the most common approach for public issues in global markets due to its flexibility, market-driven pricing, and transparency.
This comprehensive guide explains what a book building issue is, details the step-by-step process, and highlights its importance in public offerings. It also discusses the types of public issues, the roles of various stakeholders, and common terms associated with book building.
A book building issue is a process in which an issuer (typically a company) collaborates with underwriters to determine the offer price for shares in an IPO. Instead of setting a fixed price, the issuer offers a price range (price band) for the IPO, inviting bids within this range. Based on demand at various price levels, the process determines the final IPO price, known as the cut-off price, aiming to set a market-driven price that optimizes both the company’s capital-raising objectives and investor interests.
Several essential aspects define a book building issue:
Public issues refer to offerings by companies that make shares available to the general public, helping companies raise capital. You can categorize public issues into:
Companies can use the book building process for price discovery in each of these types of public issues, but investors most commonly associate it with IPOs.
The book building process follows a well-structured sequence of steps:
The first step involves setting a price band, which establishes the minimum (floor price) and maximum (cap price) bid amounts. The company and underwriters usually decide this band after thoroughly analyzing factors such as company valuation, financial performance, and market conditions.
Once the company sets the price band, it begins the bidding period for the IPO, which typically lasts between 3 to 5 days. Investors can place their bids during this period.
During the bidding period, interested investors, including retail investors, institutional investors, and non-institutional investors (NIIs), place their bids for the number of shares they wish to purchase at their chosen price within the band.
The underwriters collect bids to gauge demand at each price point within the band. Investors record demand in a “book” that reflects the volume of shares demanded at each bid price, helping determine the optimal price for the issue.
Once the cut-off price is set, shares are allocated to successful bidders. Allocation is typically on a proportionate basis if there is excess demand (over-subscription).
After the allotment, the company lists shares on the stock exchange, making them available for trading to the public at the final issue price.
The book building process is widely used due to its several key advantages:
Book building can be classified into two types based on the direction of the process:
| Aspect | Book Building | Fixed Price Issue |
| Pricing | Determined by market demand | Set in advance by the company |
| Price Discovery | Dynamic, through investor bidding | Fixed, with no flexibility |
| Transparency | High, with demand visible to all | Less transparent |
| Investor Bidding | Allows flexible bids within a range | Only at a pre-set price |
| Risk of Underpricing | Lower due to demand-based pricing | Higher as price may not match demand |
The flexibility and transparency of the book building process make it more favorable for large IPOs, while smaller issues may still utilize the fixed price method.
The book building process is essential for IPOs due to several reasons:
Understanding the following terms can help investors navigate the book building process:
A public issue of shares refers to any offering of company shares to the public. While companies use book building to determine share pricing, they can also conduct public issues through a fixed price issue. Investors prefer book building for IPOs because it aligns the issue price more closely with investor interest, while companies more commonly use fixed price issues for rights issues or smaller public offerings.

For investors interested in participating in an IPO through the book building process, here’s a general guide:
The book building issue is a crucial mechanism in the IPO process, allowing a fair and market-driven price discovery. By inviting bids within a price range, companies can assess demand accurately, achieving an offer price that aligns with market sentiment. The book building process not only optimizes IPO pricing but also fosters investor confidence through transparency and inclusivity, making it a cornerstone of modern public offerings.
A book building issue is a process of price discovery where investors place bids within a price band, helping determine the final price for shares in an IPO.
The issuing company and underwriters set a price band based on financial analysis, company valuation, and market conditions.
The cut-off price is the final price at which shares are allotted in the IPO. It’s determined by analyzing demand during the bidding process.
Reverse book building is used in buybacks or delisting, where shareholders place bids to sell shares back to the company at a chosen price.
In a book building issue, investors bid within a range, allowing flexible pricing. In a fixed price issue, shares are offered at a predetermined price with no bidding flexibility.
