Subsidiary

n. subsidiary company, company that is owned or controlled by another company

adj. supplementary, auxiliary; secondary, lesser in importance; of or pertaining to a subsidy

A subsidiary, in business, is an entity that is controlled by another entity. The controlled entity is called a company, corporation, or limited liability company, and the controlling entity is called its parent (or the parent company). The reason for this distinction is that an individual cannot be a subsidiary of any organization; only an entity representing a legal fiction as a separate entity can be a subsidiary. While individuals have the capacity to act on their own initiative, a business entity can only act through its directors, officers and employees.
