Yes, I would break it -- there's multiple things that have happened over the course of that timeframe but I would break it into 2 or 3 things specifically. The first is, and we've talked about this maybe 5 years ago, when we were having most of the conversation, is we were doing a lot -- the Life Science business is not as standard, in general, as the healthcare business. That is, every sterilizer might have some slightly different modification because you're putting it into the assembly line or the line of the company -- of the pharmaceutical company or it's a very heavily used item. So they want it engineered specifically for their purpose. Some of these things are the size of our room. And so it was a very heavily engineered business and we were not doing a good job of capturing the engineering. We were doing a good job of capturing the cost, if you will, but of the design and changes and engineering, we were not doing a good job of that 4, 5, 6 years ago. And as a result, we were under-pricing our products. We have a stopped doing that and so we now price appropriately for the work that we do for the specialty-built items, these large, specialty-built items. So that's one thing that we have done. The second thing we've done is we have quit chasing business that is pure, low-end business. And the third thing we've done is we've improved -- now I'm talking on the capital side, we've improved our plants significantly. Now most of those plants are shared with the healthcare business and so it is the healthcare business is the predominant or the large user of those factories. But as we've improved those factories and you've seen results from those factories in the healthcare business, too, but that drops through very quickly on the Life Science side. And then the second major -- other major area is on the Chemistry side. We have increased our chemistries -- the mix of our product has moved toward chemistries and, to some extent, service but certainly on the Chemistry side. And the Chemistry side is a more profitable business. So we've had a mix shift over those 4 or 5 years. We do believe that, if you look at our -- don't look at this quarter but you look at the year, we believe those are sustainable kind of numbers. You look at the quarter, we had heck of a nice quarter. We had very heavy positive mix, if you will. But yes, we do think that those kind of numbers are sustainable and we've been investing in that business and continue to invest to grow that business as opposed to, you are correct, 6, 7, 8 years ago, there were a lot of people suggesting we might want to think about exiting the business. We don't think that's appropriate.
