A public offering is the offering of securities of a company or a similar corporation to the public. Generally, the securities are to be listed on a stock exchange. In most jurisdictions, a public offering requires the issuing company to publish a prospectus detailing the terms and rights attached to the offered security, as well as information on the company itself and its finances. Many other regulatory requirements surround any public offering and they vary according to jurisdiction. The services of an underwriter are often used to conduct a public offering.
