Interesting that they added the caution again. Here's my take on what may have transpired: Teck did finish the remodel/optimization work in the 2nd Q as they said and based on their in house work they made a lowball offer for SC. This offer was rejected by EE, who essentially has the final say, and told ES that no way he was going to sellout at such a price. ES was then forced to review the work done by Teck and disagreements over the work went back and forth b/n CUU and Teck.
To settle the dispute a third independant party ( agreed to by both parties ) was hired to review it all and come up with their report - which would then be final. So here we are waiting for the results of that. Well, this is my speculation on what has happened and I add this is only my speculation. Anybody else have any theories on this is welcome to post here.
