There is a website that offers $1 plus an administration charge for the service of buying the scrip of companies that are no longer trading, allowing you to claim the loss.
The price currently on offer on market is a bargain given the debt that this company, CNP, TIM and a few other walking wounded are carrying in the current 'new world' of financial valuations.
You should only hold these stocks if you can afford a 100% write off of your capital.
My opinion only so do your own due diligence.
