holders are not liable to pay until april 21, page-4

I think that it might be related to the asx listing. Despite many "it's just like Telstra" comments, the fact is that the code does not distinguish between fixed and limited liability securities. You can find shares with a ca suffix, e.g. the t3 issue, where the liability was limited only to the market value of the security and related taxes. It has been really upsetting to watch the little guys being threatened and no one coming to their aid; Nothing on what they have had to endure though.

Nice to see them getting a bit of support.
