Ann: Trading Halt, page-91

sorry, don't know. as a generalisation usually these coys leave the announcement to the last minute - ie until prior to trading on Wed 3 Jan.
But occasionally they release the info a bit earlier.
the info they presumably will supply would not have hit them like a brick - they would have been aware of the progress of sales build-up for some time. Equally the implications on cashflow and profitability.
I think the only unknown would have been the occurrence of the S249D.
And maybe this forced the release of this info earlier?
they probably were originally intent on releasing this update as part of the Qtrly.
so could be any time between prior to trade on Tues, or prior to trade Wed.
So I am not much help on the timing.
cheers
