interim report due 8pm wed 27th, page-2

I think this is 8pm Eastern Time (ET) in the US, although even with the time difference, it still doesn't quite make sense.

I asked Investor Services at Centro about the results earlier today and the response I got was:

In regards to your previous enquiry regarding the half year results, there will be a web cast available on Thursday morning.

They did not give a specific time, but I would have thought the results will come out pre-open on Thursday. If there is other big news, we may see a trading halt on Wed, but I'd say it's unlikely. If they do halt, you'll know there is something big coming IMO.
