That would be a very complicated answer, sir. I can only tell you from the port's perspective. When you're looking at the balance in that, if you look back to your original question about the refrigerated traffic supply chain, for example, that's extremely complicated and delicate to handle. A shipper in that supply chain also has all sorts of other agreements, in terms of equipment aspects, inventories, etc.
One agreement they may have with the railroad is going to be heavily impacted with several others—the terminal operator, for the way the containers are handled, the shipping line carrier to have those refrigerated boxes available at a specific time and place. Then, there has to be an agreement with the railway about how those are going to be plugged in on mobile generator sets. That's why we're a little hesitant to say very quickly that there's an easy template and that arbitration is the end logical step. We tend to agree that, because of the complexity of it, it has to be treated as a tool of last resort.
