Through Stock exchange, Capital (economics) and Debt

When a company becomes publicly listed, the money paid by the investing public for the newly issued shares goes directly to the company (primary offering) as well as to any early private investors who opt to sell all or a portion of their holdings (secondary offerings) as part of the larger IPO. An IPO, therefore, allows a company to tap into a wide pool of potential investors to provide itself with capital for future growth, repayment of debt, or working capital.

After the IPO, shares are traded freely in the open market at what is known as the free float. The market value of a company after an IPO is determined by the share price multiplied by the total number of outstanding shares, commonly referred to as market capitalization. Stock exchanges stipulate a minimum free float both in absolute terms (the total value as determined by the share price multiplied by the number of shares sold to the public) and as a proportion of the total share capital (i.e., the number of shares sold to the public divided by the total shares outstanding). Although IPO offers many benefits, there are also significant costs involved, chiefly those associated with the process such as banking and legal fees, and the ongoing requirement to disclose important and sometimes sensitive information.

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 (initial sale). Alternative methods such as the Dutch auction have also been explored and applied for several IPOs.

History

The earliest form of a company which issued public shares was the case of the publicani during the Roman Republic, although this claim is not shared by all modern scholars. Like modern joint-stock companies, the publicani were legal bodies independent of their members whose ownership was divided into shares, or parts. There is evidence that these shares were sold to public investors and traded in a type of over-the-counter market in the Forum, near the Temple of Castor and Pollux. The shares fluctuated in value, encouraging the activity of speculators, or quaestors. Mere evidence remains of the prices for which parts were sold, the nature of initial public offerings, or a description of stock market behavior. Publicani lost favor with the fall of the Republic and the rise of the Empire.

In the United States, the first IPO was the public offering of Bank of North America around 1783.
