AMFIRST-TR vanished from the account but the new AMFIRST shares aren't in yet. I hope everything works correctly. Someone please update if you managed to get the new shares?

Dont worry, it will unvarnished itself in 2 weeks time 

My questions:
1. Renounceable rights issue of 257,400,600 new units
Is this mean that there will be 257,400,600 new mother share added to AMFIRST? Or is it just 257,400,600 units of rights?

answer:
NO,it just 257xxxxxxx unit of right will start trading on 11 of july.(The Rights commence of trading : [ 11 July 2012 ] info from bursa website)

2. RM0.83 per Rights Unit mean if I am holding 5000 units of AMFIRST, how much right I get?
Is it 5000 x 3/5 = 3000 rights? Mean I get it free in my stock account?
And the price for the rights I get will be RM0.83 each? Or I need to pay RM0.83 each to get the rights?

answer:
3000 unit of right.(trading code is [ AMFIRST-TR, 5120TR and MYL5120TR002 ]).
yes,you get free right in your account.
right is same like a voucher to let you buy a normal share of AMFIRST for RM0.83,so after all right been convert to NORMAL share after payment,the share price will adjust.if you do nothing,you will lose money because the share price is going to adjusted to around rm1
