Ann: Proposed Cancellation of London Listing, page-27

Pual Donaldson's comments about the LSE listing are probably correct if the listing was a requirement of JP Morgan and Capital One kicking in $20m and $10m equity respectively. They would want their clients to be able to trade in the UK. So it may have served its purpose and became redundant when they sold out, as only 3% of UK trades are through the LSE.
Now it is an impediment to raising equity because a prospectus would be required by the LSE causing further delay. This is not a requirement of the ASX in the planned equity raising.
De-listing is a positive sign for me.
The answer to most of the above questions is clearly set-out in the de-listing announcement.
