Under the definition the ``enterprise'' includes all related
activities performed through ``common control'' for a common business
purpose. The word ``control'' may be defined as the act of fact of
controlling; power or authority to control; directing or restraining
domination. ``Control'' thus includes the power or authority to control.
In relation to the performance of the described activities, the
``control,'' referred to in the definition in section
3(r) includes the power to direct, restrict, regulate, govern, or
administer the performance of the activities. ``Common'' control
includes the sharing of control and it is not limited to sole control or
complete control by one person or corporation. ``Common'' control
therefore exists where the performance of the described activities are
controlled by one person or by a number of persons, corporations, or
other organizational units acting together. This is clearly supported by
the definition which specifically includes in the ``enterprise'' all
such activities whether performed by ``one or more corporate or other
organizational units.'' The meaning of ``common control'' is discussed
comprehensively in part 776 of this chapter.
