The company said the plan is designed to protect shareholders from unfair takeover strategies that would limit the ability of shareholders to realize the long-term value of their investment and to ensure that all shareholders are equally and fairly treated in the event of a takeover proposal.

The plan can be put into action if a person acquires 20% or more of Manugistics common stock or commences a tender offer for 20% or more of Manugistics outstanding common stock. It also caters for voluntary merger or transfer of the majority of Manugistics’ assets.

For fiscal 2004 the company reported a net loss of $103.8 million on revenue of $243 million.
