Your next question comes from the line of Mark Kelleher from D.A. Davidson. Your line is open.
Mark D. Kelleher - D. A. Davidson & Co.: Great. Thanks for taking the question. Just wondering if you could provide any more insight into that large deal with the Tier 1 service provider, just in terms of maybe what products that involved, was it the NetScout side, was it the Danaher side, and maybe tied that into how Tektronix is doing and how you view that? I know you commented that it's returning to growth, but maybe some more detail on that. Thanks.
Anil K. Singhal - Co-Founder, Chairman, President & Chief Executive Officer: So this was, Mark, was mainly the big deal we were talking about is mainly coming from tech side of the house. And as we talked about earlier, it was sold earlier. And there were some acceptance clauses and all those. And those were all delivered. And that's what the one we talked about in the last quarter also, that we are not sure whether we're going to close this quarter, but it happened, and it went very well. So it's mainly – I mean, in this provider, we do business on both sides, both from NetScout and TekComms. And both are going well. But this particular deal was about TekComms.
Mark D. Kelleher - D. A. Davidson & Co.: So how's Tektronix doing otherwise? (47:47).
Anil K. Singhal - Co-Founder, Chairman, President & Chief Executive Officer: I think it's going as well as we – pardon, sorry. Go ahead, again.
Mark D. Kelleher - D. A. Davidson & Co.: No, I just – wondering if it's growing, what your expectations are for that now post-merger?
Anil K. Singhal - Co-Founder, Chairman, President & Chief Executive Officer: Yeah. I think it's – well, I mean, all plans are as we expected and as reflected in our guidance. And a lot of people are anxiously waiting for the combined solution also. And we are making a lot of good progress. So overall, I think we have good retention of key people. We have retention of customer and renewed interest in our solution, despite some of the spending challenges they're facing.
Mark D. Kelleher - D. A. Davidson & Co.: Okay. Thanks.
