Probably -- just probably all of those. But the improvement itself is kind of a combination of items, as you can imagine. There's certainly -- you kind of always have to look at where you're starting from, and a year ago, we were starting from a point where raw materials were in a rising environment, and there's always a lag effect between getting our price increases back. So part of that, certainly, has been our price initiatives, and as raw materials have gone up over time, to raise our prices. But that's certainly 1 component. As you also mentioned that raw materials, we have constant projects and looking at ways to lower our raw material costs or be more efficient in the way we do things, so that's obviously another part of it. So it's really -- it's kind of a combination of things. And as we've said all along, I think we target to have around 35% of gross margin area and we're targeting in that range. The second part of your question, really, was some change from our view in the first quarter. And in the first quarter -- I mean, our previous conference call at the beginning of March, we had really -- during that time period, we saw price -- raw materials going up, and they did go up in that February, March timeframe. And we are still seeing -- we're seeing more of a, I would say, more of a stabilization in our raw material cost now. We anticipated them to be up, more so in the second quarter than they're probably going to be, and I think that had to do in that March and April timeframe, the price of crude coming down. That was a big driver. Not that our raw materials are really coming down, but they' more stabilized. And when I say that is we have a whole list of raw materials, a lot of them. A number of them are still going up, some are flat, some might be declining. So but overall, our -- when you look at the mix, I'd say we're in a relatively stable environment right now.
