Well, Tom, I really don't want to get into making one-on-one comparison against CN. I will tell you, I've railroaded a long time. And in all 40 plus of plus my years of railroading, I have never gone through a winter like we have just gone through. I think in line with Fred's comment as far as this quarter being an anomaly, that's exactly what it is. As indicated in the slides in the last four weeks, you can see productivity improvement, GTMs, car miles per car day, everything you want focused in the right direction is heading in the right direction, and albeit January and February, as I said, were certainly challenging to run a one-off comparison against another carrier, I just don't want to get into that. We have certainly, as I said, Tom, done everything we could in line with the snow clearing, the extreme cold, the work through our mountainous territory but you have to imagine, it's just not trying to fight avalanches, it's predicting avalanches and working with Parks Canada, and taking your railroad out of service to disperse snow and knock down potential avalanches, so they don't get in the middle of your traffic line. I mean, we only had one train incident caused by an avalanche where an avalanche went through one of our intermodal trains. To me, that was an exceptional move as far as showing the diligence of our team, Mike's team, Parks Canada working in line with them. And again, I've never gone through anything like this in my career. And I think I'm a pretty decent railroader, and I don't want to extend the comment other than just saying, there's nothing wrong with this railroad. It can handle winter. This winter was a bit more than what any of us can even bargained for. So don't be concerned, we'll be fine.
Thomas Wadewitz - JP Morgan Chase & Co: Okay, and then a second question for you as well and I don't think there's any doubt that you are a very good railroader. But why -- I guess the decision to leave was surprising when it came out, and I would have expected that you'd be at the railroad for a couple of years or so. The kind of sense that I've had from it is basically there's a lot of travel, a lot of demands on you and perhaps, a bit more so than you'd expected and maybe that's the reason why. Is there any perspective you can add in terms of your decision to leave after what seems like a fairly short period of time at CP?
