Yes, sure. Thank you, Patrick. It's Bill. I'll start off here, and then I'll let Mark and Roger, obviously, chime in here a bit. With respect to South America, let's first focus a bit on Brazil. Obviously, we're -- it's very well known. We're seeing, obviously, a demand environment certainly lower than our expectations were at the first quarter. We certainly had expected demand to be lower in Brazil, but it's currently outpacing our expectation. So as we kind of look through the rest of the year, we do expect some recovery, as we've stated in our comments, in the Brazil commercial truck market. But on a year-over-year basis, we're looking to be down now about -- on a unit basis, about 13.2% production in South America. So I think as we flow through this -- you're exactly right on the margin front, while we have the SIFCO arrangement, obviously, it's got a different margin profile in general than all of our products. There certainly is some margin pressure with respect to our entire Brazil operation given that demand environment. I think the other piece of the puzzle is, just briefly, and we'll talk a bit about it, is what we're seeing in Venezuela. And to our comments, just very briefly, I think, certainly, our assumptions that we had in the first quarter, we're seeing production in the second quarter largely are nonautomotive or aftermarket business. I think we're getting firmer signal with respect to OE restarts later in the third quarter and into the fourth quarter. And certainly, our Venezuela team has been very diligent in working with the government with respect to settlement of currency. So I think all in all, while there's still a lot of uncertainty with respect to Venezuela, we're moving through it. And the teams are very diligent in the execution there, and I think it is firming a bit up our second half assumptions, with respect to production.
