Then there is also the US Tax form 8-BEN (or similar) otherwise a percentage of any subsequent sale proceeds will be subject to a withholding tax in the US.
The delisting moves the focus from short term ASX share price movements to obtaining an injection capital from a Private Equity or other investor to fund right through to FDA approval (say 2 years) AND commercialisation, possibly another 2 years, unless a buyout occurs. I am assuming Thorney will hold as there is no way they can sell at this stage.
