I understand its done but just want to understand all the options here , even if they all end up with the same result.

Presumably if you still have shares at this point you have a choice of tendering, sell on open market or doing nothing.   (From what I read here by tendering you dont incur a transaction fee generally...)

If you tender before March  7, you get it you get your cash ,...presumably within some timeframe.

If you do nothing and just wait then Brookfield most probably will get their 90% and you will get cashed out at the $2.60 offer whether you like it or not. 

And most unlikely , if they dont get the 90% then what happens?  I know its not likely but just curious.
