In an Undivided or Eastern Account, each underwriter accepts responsibility for selling any shares that remain unsold by other members of the syndicate. This system is designed to protect investors from having too much control over the price of the stock at IPO.Underwriters are typically large banks or investment firms that have a lot of experience in managing IPOs. They will work with the company to set a price for the shares and then sell them to investors. If there are any shares left over, they will be responsible for selling them.This system ensures that there is no one person or firm who can manipulate the price of the stock at IPO. It also protects investors from being stuck with unsold shares if demand is low.
