Yes Im aware companies can have multiple listings but it does cost abit, especially for a company with very little money !
There was a sentence in the merger announcement on 10 May 2012, that has me second guessing:

"Also important for CBD’s shareholders is the improved liquidity CBD anticipates will accompany the shift to a U.S. listing upon closing of the merger. CBD plans to apply for listing on NASDAQ because it is host to the world’s largest collection of cleantech public companies and attracts a corresponding level of investor attention.”.

This would be great, but I DO NOT want to see a delisting from the ASX.
