Hello and welcome to the next in my ‘what is’ series, this time we are looking at what is an IPO.

Previous topics cover in the series can be found here

An IPO or Initial Public Offering is a type of public offering where shares in a company are sold to investors.  An IPO is underwritten by investment banks. It is these banks that arrange for the companies shares to be listed on a stock exchange.  When a company creates shares it is usually known as floating or going public.  The company then changes from a being private company to a being a public company.

Process of going public

The first step of going public to to hire an investment bank or underwriter.  It is these underwriters that arrange the sale of the company shares to the public.  If the IPO is large enough multiple underwriters may be needed to spread the workload.  The underwriters take a potion of the share sales as a fee, this is called the underwriting spread.

The company wanting to go public also appoints a manger called a bookrunner to help determine the price the company shares should be issued at.  There are two main ways the share price is determined. The first way is where the company with help from the bookrunner fixes a price(“Fixed Price Method”).  The other way is through analysis of investor demand demand created by the bookrunner (“Book Building”).
