Quasi-corporation
A quasi-corporation is an entity that exercises some of the functions of a corporation, but has not been granted separate legal personality by statute. For example, a public corporation with limited authority and powers such as a county or school district is a quasi-corporation.
Definition
A quasi-corporation is an entity that is not incorporated or otherwise legally established, but which functions as if it were a corporation.
Federal government
When created by the federal government of the United States, these entities are commonly called quasi-public corporations. These now or in the past have included telegraph and telephone companies, oil and gas, water, and electrical power companies, and irrigation companies. Some examples of quasi-public corporations in the US are Sallie Mae, Fannie Mae/Freddie Mac, Amtrak, the Communications Satellite Corporation, and the US Postal Service.
In the United States, such entities established, supported, or controlled by a city, county, or township may be called quasi-municipal corporations.
