Correct me if I am wrong but this 15%, if lost, in reality represents about a 22% reduction in overall profit for the company. If they expect US$4B profit with a 66% share, that would reduce to around US$3B at 51%. Roughly 22% reduction in profit. So, the company should be worth A$4.3B instead of A$5.7B at a PE ratio of 1.0 or $1.20 per share. Again, please tell me if I have got this wrong...
