Ann: SP1 delisted from ASX, page-349

hi
Just wondering if anyone has any advice on how to write this off as a loss so I can claim it on tax and not have to worry about being involved in this any more.
As far as I'm aware our shares exist in a now empty company, and we were given shares in ISXFEU but they don't have a market to trade on? Can the ISXFEU also be sold off market to something like delisted? would we have to pay some sort of taxes for being given these shares?

The drama / crapping on is just a bit too hard to read through
