A Subsidiary is a company controlled by another company. Control occurs when the controlling company owns more than 50 per cent of the common shares. When the parent owns 100 per cent of the common shares, the subsidiary is said to be wholly-owned. When the subsidiary operates in a different country, it is called a foreign subsidiary. The controlling company is called a holding company or parent. A subsidiary is a corporation with its own charter and is not a division of the controlling company.
