Ann: Tremont Makes A$0.33 Per Share All Cash Offer for Cradle, page-54

it's a cash offer, so you'll get 33c/share owned funded to you. Details on timing aren't released but assuming it gets through, whatever details you've put to computershare they will send your money to you (as a cheque or direct deposit etc).

Tremont will own all of the assets (including cash and liabilities) that CXX currently has.

It's a pretty simple offer in that regard, it's just the timing that sucks as it usually takes 2-4 months (in which the stock is suspended) to get your money. That's why people are selling now at lower than 33c, it's guaranteed to come today (or after settlement) and if the takeover does fall through there is a risk the stock falls back to previous levels. So that's why the buy/sell isn't at 33c.
