Digitas today adopted a "shareholder rights" plan that, if upheld in court, would make it more difficult for it to be acquired involuntarily, according to MediaPost. The plan would effectively make it about twice as expensive for a buyer to control Digitas - due to a special stock dividend triggered by anyone gobbling up shares without the company's assent. As is typical of these management self-protection mechanisms, Digitas's senior management will receive a variety of goodies if someone conducts a hostile takeover. Sometimes these provisions are put in place when a specific hostile threat arises, although Digitas hasn't indicated any such interest. It will announce financial results tomorrow, and analysts will be able to question the now very protected management as to their motives.
