In terms of whether we think it will give some more leverage to the shippers, in short, the answer is yes. In our case, for example, we already have a commercial agreement established with CN, and in there we do have dispute resolution processes that we follow, and we follow them to great success. It's a joint effort of both parties to pursue those dispute resolutions, but I think we approach the situation as equals, and the service-level agreement will allow people to do that.
What I would argue, though, is that I think arbitration is a little heavy-handed. I would really be in favour of pursuing mediation. When we've run into situations in the past, we've sought third parties that can provide some perspective. That would be my comment on that.
