A corporation is an organization—usually a group of people or a company—authorized by the state to act as a single entity and recognized as such in law for certain purposes. Early incorporated entities were established by charter. Most jurisdictions now allow the creation of new corporations through registration. Corporations come in many different types but are usually divided by the law of the jurisdiction where they are chartered based on two aspects: whether they can issue stock, or whether they are formed to make a profit. Depending on the number of owners, a corporation can be classified as aggregate or sole.
