Your next question comes from the line of Patrick Ho from Stifel, Nicolaus. Your line is open.
Patrick J. Ho - Stifel, Nicolaus & Co., Inc.: Thank you very much, and congrats on a nice year. Bob, first on the display side. Typically, it's always had little bit of a lower gross margins relative to your Silicon system. As this transition to OLED begins, is there any potential, I guess, margin improvement you see with the product portfolio and things that you have done on display side of things?
Robert J. Halliday - Chief Financial Officer & Senior Vice President: I think display gross margins will improve over time. I think that in this year of early adoption of some of these new tools, I think they're okay. And then they get better through the end of the year into next year. The second thing that we talked about I think on the earlier calls is that the mix of tools we sell into small screens versus TVs. TVs is a sweet spot for us in terms of mix of tools and gross margins. It's a little bit different mix down at the smaller screen side with little lower gross margins. And as we mature our positions there, they should get pretty good. So by the time we're done, you'll see gross margins more attractive in display over the next year or two.
Patrick J. Ho - Stifel, Nicolaus & Co., Inc.: Great. That's helpful. And Gary, maybe a question on a bigger picture related to EUV and potential capital intensity increases on future technology nodes on the logic end. Have you had any customer discussions that have highlighted, hey, EUV could be further delayed? What are you guys going to do to help us out? And maybe potentially, especially since your models are based on EUV getting the 7-nanometer logic node, maybe just on a big picture basis, what are some of the, I guess, additional incremental opportunities for Applied if EUV misses this next node?
Gary E. Dickerson - President, Chief Executive Officer & Director: Thanks for the question, Patrick. We have a number of very deep engagements with customers in patterning. Certainly patterning cost is one area that's a big focus, but also from a yield standpoint, edge placement errors are another area that is a big focus for our customers. And this is another area where, again, materials innovation, materials engineering, there are some really great opportunities for us. So as we continue to drive new capabilities with the new products that we've introduced over the last three years, the combinations of those products we also see tremendous opportunity. So the engagements that we have with customers I would say are further out, broader, deeper than we've ever had. And this particular area is one that is a huge focus for all of our customers.
Patrick J. Ho - Stifel, Nicolaus & Co., Inc.: Great, thank you.
