Good morning everyone. And thanks for taking the questions. Just two quick ones from me here this morning, maybe Walt or Mike. If you look at Isomedix in the quarter, solid mid-single digit growth, but historically we've seen that in kind of the upper single digits. And I realize you've brought on new capacity. We've seen fairly positive commentary from a number of the Healthcare service providers out there, just in regards to procedure volumes during the quarter. Help us think a little bit about lead lag with your end customers relative to what we see on the service side, and kind of maybe reframe our expectations for unit volume growth in that business? And then I have a follow-up. Thanks.
Walter M. Rosebrough - President, Chief Executive Officer & Director: Sure Chris. We do see a lead lag and unfortunately it's not uniform. Between what sales are, not so much on the service side of that business, but on the device volume side. So if you watch device volume globally – high-end device volume or devices that have to be sterilized volume globally, we will tend to track that. We lead in lag based on their expectations and how they build inventory and don't build inventory, and how their hospitals build inventory and don't build inventory of these products. And sometimes they get it right and sometimes they get it wrong. Over long stretches, six months, a year, we will tend to track that very closely; over short stretches, it varies. And then the other thing that causes it to be, again, somewhat not as uniform as what you might expect, is our pricing tends to be fairly stable in that business, so we go up kind of with inflation kind of numbers. And so our prices are a little more stable, whereas sometimes they get very strong price increases because they bring in new products, which is typically the way devices get strong price increases. And then sometimes if they have less new products, or they're having GPO pressure or whatever, they may not get the prices. So where volume – if you're talking strict volume, unit volume, as opposed to revenue volume, which has some price effect. And often, new products pricing is buried in revenue volume, because it's a new product so it doesn't have a historic price. If you can kind of work through that, then our volumes or our volume growths tend to be very similar to the global medical device growth. So that's kind of a long answer to a short question but that's how we typically see it.
