The performance of related activities through ``unified operation''
to serve a common business purpose may be achieved without common
control and without common ownership. In particular cases ownership or
control of the related activities may be factors to be considered, along
with all facts and circumstances, in determining whether the activities
are performed through ``unified operation.'' It is clear from the
definition that if the described activities are performed through
unified operation they will be part of the enterprise whether they are
performed by one company or by more than one corporate or other
organizational unit. The term ``unified operation'' has reference
particularly to enterprises composed of a number of separate companies
as is clear in the quotation from the Senate Report in Sec. 779.215.
Where the related activities are performed by a single company, or under
other single ownership, they will ordinarily be performed through
``common control,'' and the question of whether they are also performed
through unified operation will not need to be decided. (Wirtz v. Barnes
Grocer Co., 398 F. 2d 718 (C.A. 8).)
