Might be a few weeks out on this but for US investors this may help with a decision. I held FWR and accepted the share swap for Cliffs. The CLF sp climbed up almost every day for a while and I ended up sell neat the high. Only thing I did not like is I did not have control over the CLF shares for 2 or 3 weeks. Not that I would have sold but have liked to had the option. If Cliffs offers a share swap offer I will take the swap and see if lighting strikes twice.
I am still onboard with a KWG merger at the current offer.
