Ann: Half Yearly Report and Accounts , page-9

""Broker advised Tregonnimg needs cash for a very expensive property he bought, time will tell if this is right as has to lodge change of shareholding notice.""

If I undrstand it correctly that would be every 1% change in his holding of AED.
AED total shares 154,791,782 so ~1.5mil shares = 1%

According to the 2008 annual rpt Tregonning holds/controls 27,166,699 shares and Dix has 37,558,613.

Those large holdings of Dix and Tregonning explain the divvy payout last year, $30mil/20cps.
