I'd say the delay was due to them totally reorganising the schedule for the demerger, the Entitlement offer is now coming first along with the shortfall offer.
The Record date for the Entitlement offer is next Thursday
So the last day you can buy or already own FFX shares to participate in the offer is
this coming Tuesday
1:1.4 distribution with the record date for the in-specie distribution Monday June 6
Total shares on issue based on an issue price of 70c gives a market cap of $788m to $838m (depending on whether they raise $50m or $100m)
