I would say the following. Keith used to be my COO, and we did that, so we can take credit for that while he was at CN, and I know they're doing it at CP. We've actually expanded the concept of service level agreements across Canada. It's caught on like wildfire in the intermodal space. We have a number of them in a number of other commodity groups, in merchandise, in bulk.... The concept is prevalent and we welcome it.
In grain, we have service level agreements. They tend to be more operational, for a very simple reason. We operate under the revenue cap. The notion of having a normal commercial relationship where there are commitments and reciprocity is not the way the system is built at the moment. I'm not here to start a debate on the revenue cap, but the reality is that in any commercial business, you take revenues, you take commitments, you make a contract, and you have service level components to it. When the price is set and when the assets have to be there no matter what in a regime where it's pay as you go, the notion of service level agreements falls on its own head.
