(by waiting till the last minute to give their intentions).

Or more likely, wait until they are forced

Teck has very different needs as a company

They are sitting on a mountain of cash, their operating units are all performing

There is no particular internal pressure on them to take action

So what's the hurry...

If CUU really believes that Teck is feeling any urgency or will take the initiative to move this forward in a timely manner, thety are dreaming

CUU must rely on the fact that the controlling agreement sets out specific values, timelines and actions and that in order to get Teck to move, they must insist on specific performance

...and this does not mean letting them interpret any part of the agreement strictly as they see fit

That is not what AGREEMENT means
