ewere,

A company on the asx is only allowed to remain in trading halt for 4 days. After that period if it does not commence trading it is then suspended. This is what has happened to MST, it is now suspended. In order for the stock to trade it has to re-apply to the ASX, and may have to meet chapter 1 & 2 of the listing rules etc, makes it just that little harder. The next problem is non payment of the ASX listing fees as that will result in the company being de-listed and a large hurdle to overcome and an Administrator generally will not pay them.

In order to claim a tax loss you generally require a letter, from a liquidator or similar, to say that the company has been wound up etc and there is no chance of recovery. This is of course subject to advice, in respect to your individual position, from your professional adviser.
