Initial Public offering

Initial public offering (IPO) or stock market launch is a type of public offering in which shares of a company are sold to institutional investors[1] and usually also retail (individual) investors; an IPO is underwritten by one or more investment banks, who also arrange for the shares to be listed on one or more stock exchanges. Through this process, colloquially known as floating, or going public, a privately held company is transformed into a public company. Initial public offerings can be used: to raise new equity capital for the company concerned; to monetize the investments of private shareholders such as company founders or private equity investors; and to enable easy trading of existing holdings or future capital raising by becoming publicly traded enterprises.

Details of the proposed offering are disclosed to potential purchasers in the form of a lengthy document known as a prospectus. Most companies undertake an IPO with the assistance of an investment banking firm acting in the capacity of an underwriter. Underwriters provide several services, including help with correctly assessing the value of shares (share price) and establishing a public market for shares.
