Its an indicative offer so no document to complete yet, BMO have until the 24th Feb to make the offer which as at today price is based on a premium price of 28 per cent. Until the offer is confirmed no action required by you. If offer agreed document will ge sent to you for completion and return , watch out for closing date re sending form back. There will be a clause in the offer of the minimum percentage of acceptance required for the take over to be accepted. Not knowing how much you paid per share cant comment on accept or decline offer, only you can make that decision. Good luck.
