Subsidiary(redirected from subsidiariness)
Also found in: Dictionary, Thesaurus, Legal.
A company that is publicly-traded but has more than half its stock owned by another company, known as the parent company. As long as the parent company owns more than half the stock, it maintains control of the subsidiary, though its other stock is still traded. Some subsidiaries belong to the same industry as the parent company, while others do not, and are part of a diversification effort on the part of the parent company. See also: Wholly owned subsidiary.
