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.
