It seems Orbis has a track record of buying controlling stakes of 'down and out' company's such as Isoft in hopes of achieving a takeover premium:

Seems like they have stuffed Warren Buffett over a couple of times with Cannon and the like.

I wonder if they intend to accumulate a larger position, especially since their current average is 38.5c... well above the current SP...

Just the ramblings of a smelly bottom picker.
