Flag of convenience: History & Applications
Flag of convenience (FOC) refers to a business practice whereby a ship's owners register a merchant ship in a ship register of a country other than that of the ship's owners, and the ship flies the civil ensign of that country, called the flag state. The term is often used pejoratively, and although common, the practice is sometimes regarded as contentious.
