I think you are wrong on the following "If they get more than 90% they will takeover the remaining shares but the price must,by law, be at a fair market price at that time."
According to the AEL Bidder's statement the 90% level may trigger a compulsory buyout of the remaining shares. This will be done at the bid price (42 cents) not at a valaution price.
I am 99% certain of this, but happy to be proven wrong.
