Public Company
A public company is a company whose ownership is organized via shares of stock which are intended to be freely traded on a stock exchange or in over-the-counter markets. A public (publicly traded) company can be listed on a stock exchange (listed company), which facilitates the trade of shares, or not (unlisted public company). In some jurisdictions, public companies over a certain size must be listed on an exchange. In most cases, public companies are ''private'' enterprises in the ''private'' sector, and "public" emphasizes their reporting and trading on the public markets. Public companies are formed within the legal systems of particular states, and therefore have associations and formal designations which are distinct and separate in the polity in which they reside. In the United States, for example, a public company is usually a type of corporation (though a corporation need not be a public company), in the United Kingdom it is usually a public limited company (plc), i ...

Chief Operating Officer
A chief operating officer or chief operations officer, also called a COO, is one of the highest-ranking executive positions in an organization, composing part of the "C-suite". The COO is usually the second-in-command at the firm, especially if the highest-ranking executive is the chairperson and CEO. The COO is responsible for the daily operation of the company and its office building and routinely reports to the highest-ranking executive—usually the chief executive officer (CEO). Responsibilities and similar titles Unlike other C-suite positions, which tend to be defined according to commonly designated responsibilities across most companies, a COO's job tends to be defined in relation to the specific CEO with whom they work, given the close working relationship of these two individuals. The selection of a COO is similar in many ways to the selection of a vice president or chief of staff of the United States: power and responsibility structures vary in government and priva ...
