So Kevin, good questions. I think -- we were in lots of different end markets and we’re in lots of different -- that follow lots different cycles. I think our experience from the recession that started in 2008 was that, probably, we -- even though that we’re in lots of different end markets that we'll probably start to see things sort of in mid-cycle. So we're very -- compared to some other companies, we're not one of the first ones to see something that's happening either good or bad. We usually -- it usually, it takes maybe a couple of months. So we recognize that. So we follow lots of other companies to see what they're saying or seeing. As I mentioned earlier, I mean, one of our biggest customers, Caterpillar, so we follow their forecast very closely. And a month ago, they increased their sales guidance for calendar '11 over their previous guidance. So we're very focused on watching things. We hope that it doesn't -- things don't fall off, but we're going to -- we’ll watch, and then we'll react proactively, if things do weaken. In the IFS business specifically, you asked about -- that, for us, is clearly a mid-cycle business. The equipment side of it, that typically if people have projects underway, new capital projects, new plants where our equipment is incorporated, they'll continue with those. So it ends up being a mid-cycle. But the replacement part of that business, which is about 40% of the sales is an earlier cycle. And we've seen that business, as we mentioned in our comments, has been very, very strong, which indicates that people are using the equipment, the production equipment, that's out there in the field.
