The fundamental purpose on this procedure is to elicit information from informed investors. An appropriate price is expected from this process that generally induces investors’ attraction. The process of bookbuilding begins with consultation between all related parties, deriving a price range with a median point at which the demand for the company’s share is in maximum. The investment bank, as underwriter in equity offering, then fixes a price range for the issue. Investors are informed about the price range, then bid at a price they mthink more appropriate. The bid is conducted within the registration period and before the offer price is finally set, that should be a short-time before proposing the offer price but long enough to operate and evaluate a survey.
