Takeover prices have nothing to do with the current share price. Its based on cash on hand, current income streams and future earnings. Companies set acceptable multiples of these factors and then make an offer.
In BTA's case how long in a piece of string. What revenue will LANI earn, will swine flu worsen or another virus appear and how much Relenza will be sold in the coming 3-5 years
Got to think a takeover would be greater than $5.....
