5% share ? I fart in your general direction.
It's obvious that Starboard wants to just get out of the stock and not take too big a loss. They don't believe there is value "locked up". They just want to find somebody who is fool enough to buy it before it hits the ground and one is left selling to the scrap yard. As for the top brass at Compuware ... hey they just want to hold on to their jobs as long as they can.
You don't need a weatherman to know which way the wind blows, just take a sniff.
