Takeover regulation definitions set who is an acquirer, what constitutes control, and who acts in concert. Regulation 2 defines core takeover terminology: an acquirer includes any person who directly or indirectly acquires or agrees to acquire shares, voting rights or control of a target company; control includes the right to appoint a majority of directors or to direct management or policy decisions but excludes mere office holding. The regulation also defines persons acting in concert, listing categories presumed to coordinate acquisitions, and sets operative terms for offer mechanics such as offer period, tendering period and identified date.
