But we all got new shares. So I am asking for opinions (not advice) on whether this resets the CGT clock. If say if you sold 10% after a big run on finding oil, would you be charged full CGT (as opposed to the discount on shares held longer than 12 months) on those shares as they would take the LIFO (last in first out) position.
So say we run to 11 cents on a hit (for arguments sake) - and someone sold 10% of their holding - that would mean full CGT on shares bought at 1.1 cents in the recent CR.
Ouch. But I suppose it's a problem I could learn to cope with.
