None out of the ordinary in the quarter is what I would say. You always have an FCC unit here, an FCC unit there doing a trial, ensuring the refineries. They're not stupid. They use that to keep everybody in line, as well as to see if there's other performance requirements, P.J. So I didn't see anything out of the ordinary. There's one thing, I'd like -- I've gotten a lot of questions about this both on the call and then some follow-up calls when we're out with analysts. And I'd like to talk just for a little bit about our view on valuation in FCC Catalysts. In 2004, before -- when we went to buy the Akzo Nobel refinery catalyst businesses, there was an article written by McKinsey that said FCC was a commodity and should be priced as such. And at that point in time, in 2004, when we bought the business, there was about -- we were selling, or Akzo was, about 125,000 metric tons roughly of FCC catalysts at about $1,000 a met ton and it was breaking even. Subsequent to that, after we paid the multiple we paid for that business, we looked at the value that, that product was delivering, we looked at the performance, we looked at our technological advantage and we started pricing for the value that the product brought. Now when we led that price increase, our volume went down to 85,000 metric tons. So we were down 25% to 30% on the volume. Today, however, the base price is well north of $3,000 and we're still not back to the volume we were in 2004, but it is a better business because we're delivering value to the refiners on the technological performance that we deliver. That's what this business is all about. Customers are going to have trials. And if the crude slate's working your way like it happens to be working our way on FCC catalysts right now and you're delivering value to those refineries and making them more profitable, they're going to switch. They're not going to switch on price unless the performance is equal. So I really -- this is not something as easy where a competitor or Albemarle or anybody else can go out there and try to buy share. It's a performance sale. It has been since we started this thing in 2006 to 2007.
