In these sections, companies and organizations have an entry  containing their addresses and in the majority of cases, the names of  their  main executives, as well as other valuable information such as any branch  office, clients and allied companies.  To make the searching more  user-friendly among the names of executives and the registered companies,  there are another two sections ( Who Is Who and Companies).
