Obviously there is some flux in holdings... and how frequently these individual sites have their computers run over this information for every company they follow...Marketscreener and AFR still list both Brookfield holdings - but also break out the Childrens investment fund from the nominees... hopefully this may give you more insight.

Also remember that Brookfield only sold 9% and the transaction occurred on the 10th - so a substantial holder notice (if any) will only be required from today at the earliest
