Wholly Owned Subsidiary
Wholly-owned subsidiary is an investee, all of whose shares are owned by the investor.  The investee may have publicly traded preferred stock and debt, but all of its common stock is owned by a parent company and is unavailable for purchase.  They are owned outright, and there are no minority share owners.  Thus, all of the activities of the wholly-owned subsidiary are part and parcel of the parent company for both operating and reporting purposes.
