Which exchange/What price, page-12

I'm wondering if/when we list overseas how will CGT work on any sale of shares on the overseas market. Every holder has now held their ISX shares over 12 months so are entitled to the 50% discount on the ISX shares on the ASX but with the demerger and listing OS does the 50% discount apply immediately as the new asset ISXFEU was demerged from the original purchase of ISX or is it deemed a new asset? Will the cost base be 10x the ISX purchase price on the ASX or calculated another way?
