you are all wrong apart from price, page-13

Listing Rules/chapter 7 under the ASX deal with capital raising and capital reorganising.
http://www.asx.com.au/ListingRules/chapters/Chapter07.pdf
Under these listing rules a company may not in any 12 mth period raise capital greater than 15% of existing equity without shareholder approval. The rule reads something like:-
Subject to certain exceptions, Directors are restricted by listing rule 7.1 from issuing or agreeing to issue new securities in the Company in any 12 month period, which amount to more than 15% of the Companys ordinary securities on issue without Shareholder approval -
("15% limit").
7.1 allows directors to issue more than 15% without sh approval based on numbers of fully paid shares and partly paid shares on issue 12mths prior to the current issue.
There's a little bit more to 7.1 than this, but I think overall it is designed to limit the numbers issued over 15%.

I am not au fait with the numbers on issue 12mths ago.

Now I don't recall being asked for approval, so, based on the current fully paid issue of 635m (Nov05Ambrian), I make the following calculation:-
635m x 15% = 92.25m new issue, divided into the $15m cap raising suggested in todays SMH, = a placement at 15.748 cents, or fairly close to the average sp over the last 4 or 5 wks, will occur.

However, I don't believe we have had to wait this long for something as simple as that. There is more than one thing going on here, and it may take a few days more to find out all.
On the Nido website hm pg with the link to the recent Ascope pics. DW states - More news in the next few days. Cheers Dave Whitby. 6 December 2005
