I used to have ZFX shares but now i can see 2,395 Oxiana shares showing up in Commsec but there is zero showing in purchase price. How do i calculate the buy price so that i can see an accurate reflection of loss/gain? Hope that makes sense. Let's say i had 750 ZFX shares and i paid an average of $7 a share. I now have 2,395 Oxiana shares. That means i paid a total of $5,250 for my 750 ZFX shares (750*7). So do i then divide 5250 (total cost) by 2,395 (Oxiana shares)? This gives me $2.19 (5250/2395 = 2.19) .... is this the amount i paid for my Oxiana shares in order to work out CGT? thanks
