Industries in the Management of Companies and Enterprises subsector
include three main types of establishments: (1) those that hold the
securities of (or other equity interests in) companies and enterprises;
(2) those (except government establishments) that administer, oversee,
and manage other establishments of the company or enterprise but do not
hold the securities of these establishments; and (3) those that both
