The only thing I would briefly make a quick comment on in terms of the kinds of charges you're talking about—and I think Shauntelle did a good job of explaining our view with respect to demurrage—is our understanding that we are operating a network business. It's complex and the assets aren't just dedicated to one customer in a particular instance like that, because the assets have value throughout the network.
But I would say that we also have situations where a customer is willing to make a commitment, and Mr. Dinning looked at this pretty extensively. Whether it's a commitment at a level that includes some kind of a forecast to us, or taking it to the next level, and bringing it up to an actual commitment for traffic, then we can talk about how we would deal with that in a situation where we don't meet our commitment once the customer has put his commitment into the agreement with us. So that's not an uncommon situation for us at all.
