Ann: SP1 delisted from ASX, page-455

You can still see the shares in your Computershare account; They have now changed from Chess sponsored to Issuer Sponsored.

As for selling them, you could look at delisted.com.au, they will buy worthless shares for a fee.

The company may be worth a small amount in the future, as they still have Net Tangible Assets, ie cash and a loan to ISXFEU. NTA was valued at 0.7c per share in their last financial report.

As they are still waiting for an ATO ruling regarding the demerger, I suggest you seek professional financial advice about tax issues.
