Your next question comes from the line of Steve Beuchaw from Morgan Stanley. Please go ahead.
Steve C. Beuchaw - Morgan Stanley & Co. LLC: Hi. Good morning, everyone.
Marc N. Casper - President, Chief Executive Officer & Director: Good morning.
Steve C. Beuchaw - Morgan Stanley & Co. LLC: One question on the balance between consumables and instruments. It's a little difficult, given the relative impact of the selling days issued here in the quarter, to look at on an organic basis how consumables are tracking relative to instruments. Maybe not necessarily for the quarter, but on a trailing two- or three-quarter basis. Could you give us a sense for how consumables are tracking relative to instruments? And historically, as cycles have strengthened, you might have seen a few more points of strength early on in instruments. Is that happening here? And if we see more consumable strength going forward, what does that mean on a relative basis for the potential for margin expansion?
Marc N. Casper - President, Chief Executive Officer & Director: So I'll start. When I think about the instruments business, and you look at it, very little revenue effect from days. About 6% organic growth in the quarter, in terms of how the instruments business did. Which, when you peel that back, you have a large chemical analysis business serving some very weak sectors of the industrial market, and then a very large chromatography and mass-spectrometry business. So, when you think of that level of growth, it's very strong performance, and that's been like, that bifurcation of weak industrial, weak chemical analysis, very strong life sciences, mass spec, and chromatography, has been a continuation trend. So that business is good. From the consumables mix – and pretty steady on good performance, right? Our channel business has done well; Life Science Solutions has done well. When I think about profitability, it's not a huge driver. We make a little bit more money on consumables for the self-manufactured portion, but embedded in there is the channel business. So, as you know, we don't manage the mix that way, but generally I'm not concerned by sort of the rates of growth in the businesses. In fact, the consumable growth shows that we have pretty steady, stable performance in the end markets.
Steve C. Beuchaw - Morgan Stanley & Co. LLC: Got it. And then just one clarification. Can you remind us in the outlook for the year, to what extent you've incorporated expectations for stronger trends on the NIH in the back half, given the normal 3Q disbursements that one would expect? Thanks.
Marc N. Casper - President, Chief Executive Officer & Director: Yeah, so we pretty much expected the funds to flow from NIH in the first three quarters. And as you alluded, probably the strongest in Q3. But it should be reasonable in each of those three quarters during the course of this year.
Steve C. Beuchaw - Morgan Stanley & Co. LLC: Thanks so much.
