Ann: WGO: Strike's Second Supplementary Bidder's Statement, page-57

they are both required to keep their offer open until its closing date.
there were no conditions, I think, on either of those offers (?), so no conditions or excuse to close it early.
there is also the "truth in takeovers" provisions to comply with.
I am not sure if STX can close or withdraw offer on basis that it has not officially opened - but why would they, as they have got the support of that other 10% of s/h who want to see a merger.

Whoever purchased that 15% had 2 Business days to lodge a Substantial SHareholder Notice.
Anyone who acquires an interest in 5% or more, must lodge the Notice.

Anyone recall which day that 190m or so was traded??

So 2 Business days after that trading day - so today or tomorrow ????

If no Sub S/H Notice is lodged, then it must mean that the parcel was purchased by a number of different parties - who must all be unrelated.

they probably have until close of business today?

If Media is saying it is MIN, then odds on that is who purchased the parcel.
