2) deListed (Australia)

http://www.delisted.com.au/aboutus.aspx

This website is published by deListed, a division of BRG Pacific Pty Limited (ABN 64 003 142 372), holder of Australian Financial Services Licence No: 264673.

deListed provides updates and information on failed companies including those in external administration and companies suspended from ASX, NZX, NSX and BSX. It also has all historical name changes and delistings for these exchanges and carries administrators/liquidators declarations for Australian companies for tax purposes.

Background

deListed and this website delisted.com.au were established by BRG director, Tony McLean, in response to problems experienced by shareholders when their investments turned sour. Tony was the Australian Shareholders’ Association’s CEO for nine years until the end of 2001. In that role he often assisted angry and frustrated shareholders in delisted companies. Having seen their investment fail, these shareholders were then left in the dark about the fate of their companies. Company directors denied responsibility and could not be found. Shareholders did not know who was responsible. They were unable to establish if there was any chance of a recovery. It was difficult to track down external administrators. Shareholders often waited years for a liquidator’s declaration. (The issue of this declaration is a Capital Gains Tax Event enabling the crystallisation of a capital loss for tax purposes.) Many shareholders never received this declaration or knew that it had been issued. The eventual launching of this website on 1 September 2002 had its genesis in a commitment to a group of ASA members in 1998, following a spate of requests for information.
