Okay, Jamie, I'll comment a little bit and Matt Fearon is on the call here with me and he can add to this. As you look at the AWP business, we are encouraged by the first quarter. It was a bit stronger, perhaps, than we were expecting, but -- at least, on a margin basis. That is something that we feel is a reflection of the discipline that's taking place in the market. It's also the stage of the cyclical recovery that we're at. We have a situation where our customers are healthy and they need equipment, and our supply base is positive about supporting us, which means that we have a little bit more leverage there, and so we're getting some cost reductions from our supply base, steel and other costs. I mean, on the flip side of that, our business is good, and probably one of our biggest challenges is having our suppliers meet our needs as we go forward. We had a tremendous reception to our SX-180 product introduction, the tallest, largest boom, at least, in the market that's not truck-mounted. We believe that will be a great profit opportunity contributed to our customers, as well as to ourselves. So as I look forward, we have a rational industry with a couple of players. There is some risks in the industry, and we always hear about the Chinese player that wants to come in to the business, but we haven't seen a lot of activity there. So we're being a little bit cautious in our outlook, perhaps. But we're probably balancing that against an optimistic outlook, perhaps, in our MHPS business. So we're not really going to go in and change anything at this stage until we see how the second quarter comes in.
Jamie L. Cook - Crédit Suisse AG, Research Division: I guess, Ron, just to follow up, how much did the steel or supply chain benefits help the first quarter? And did that -- I mean, do you assume that goes away in the back half of the year or material cost, et cetera come up? If you could just say how much that helped actually the margins.
