A subsidiary, subsidiary company, or daughter company[1][2][3] is a company completely or partially owned or controlled by another company, called the parent company or holding company, which has legal and financial control over the subsidiary company.[4][5] Unlike regional branches or divisions, subsidiaries are considered to be distinct entities from their parent companies; they are required to follow the laws of where they are incorporated, and they maintain their own executive leadership. Two or more subsidiaries primarily controlled by same entity/group are considered to be sister companies of each other.
Subsidiaries are a common feature of modern business, and most multinational corporations organize their operations via the creation and purchase of subsidiary companies.[6] Examples of holding companies are Berkshire Hathaway,[7] Jefferies Financial Group, The Walt Disney Company, Warner Bros. Discovery, and Citigroup, which have subsidiaries involved in many different fields. More focused companies include IBM, Xerox, and Microsoft; they and their subsidiaries primarily operate within the tech sector. These, and others, organize their businesses into national and functional subsidiaries, often with multiple levels of subsidiaries.
A subsidiary functions as a separate legal entity rather than a division of the parent company. It is sometimes referred to as a daughter company.
