What I heard at the time was this:
Autonomy: We are for sale for $6billion
HP: We'll give you $11billion
Autonomy: Errrrrrr. OK! :D
If you put your car up for sale for £600 and someone tries to buy it, but for £1100 and forces the cash in to your hand, are you really liable for overcharging them?
Autonomy didn't think they were worth that.
HP finance people didn't think they were.
But Leo and his adviser decided $11bill was a snip as they could make it worth $17bill!
In reality they made it worth about $3.5 bill.
Autonomy should point out prior behaviour to the court too.
They are far, far, far, from the only company HP have bought and messed up.
