Ann: Change in substantial holding, page-16

That's all correct. With a 'best and final' status, Wyloo's offer cannot be amended unless a competing offer emerges, which isn't going to happen.
Furthermore, with a previously disclosed ~62+%* shareholding, AF effectively has the numbers to push through a Special Resolution (via EGM) to delist MCR. (It wasn't until Wyloo crossed, say, 60% ownership that they could be sure with any degree of certainty they had the numbers to force through a delisting Special Resolution. It shouldn't come as a surprise to anyone to see their recent update highlighting their intentions in that regard after crossing that notional threshold.)

(*Edit: Updated to 70.4% today, in real-time, as I type this reply. It looks like IGO just accepted. Relevant disclosures (from IGO and Wyloo) to follow v.shortly.)
