(2) The policy may provide that the term “employees” shall include:
(i) the employees of one or more subsidiary corporations, and the employees, individual proprietors, and partners of one or more affiliated corporations, proprietorships, or partnerships if the business of the employer and of the affiliated corporations, proprietorships, or partnerships is under common control;
(ii) the individual proprietor or partners if the employer is an individual proprietorship or partnership;
(iii) retired employees, former employees, and directors of a corporate employer; and
