If no deal thereif nothing comes of this speculaiton, then the floor will imo be set by the price Cinven gets for the sale of their bloc which i suspect is closer to the spike price post announcement ----- more in the $US 30 to $US40 range.
why would they sell low - because they probably marked it down at the end of 2015 to the closing price of around $US 40 and used the loss against the huge gain they made on the sale transaction.
on a go forward basis their cost then isn't $US80 plus it is likely half that so you have to look at their exit price relative to the market trading. getting $US35 on a stock that was basing in the low $US20's is still good from their perspective imo.
if we get a go forward floor into the mid point of $US 35 then i am ok holding as the 12 to 18 month horizon looks good here for a double over that floor.
