subsidiary -
a company that is completely controlled by another company
A subsidiary, in business matters, is an entity that is controlled by a separate higher entity. The controlled entity is called a company, corporation, or limited liability company; and in some cases can be a government or state-owned enterprise, and the controlling entity is called its parent. The reason for this distinction is that a lone company cannot be a subsidiary of any organization; only an entity representing a legal fiction as a separate entity can be a subsidiary.
