Holding company.
(C) Holding company. For purposes of this paragraph (e)(5)(i), an entity is a holding company if its primary activity consists of holding (directly or indirectly) all or part of the outstanding stock of one or more members of its expanded affiliated group. A partnership or any other non-corporate entity shall be treated as a holding company if substantially all the activities of such partnership (or other entity) consist of holding more than 50 percent of the voting power and value of the stock of one or more common parent corporation(s) of one or more expanded affiliated group(s). If a partnership or other non-corporate entity owns more than 50 percent of the voting power and value of the stock of more than one common parent corporation of an expanded affiliated group, each common parent corporation's expanded affiliated group will be treated as a separate expanded affiliated group for purposes of applying the rules of this section unless a non-corporate entity is treated as the common parent entity of the expanded affiliated group in accordance with 1.14715(i)(10).
