Hi. Great. Thanks very much. Maybe, Bob, if you could circle back on NFX, you mentioned earlier in the presentation, if you could talk a little bit about the pricing that you've been increasing on which contracts and what the EPS drag from NFX is now and where you expect that to go in 2017?
Robert Greifeld - Chief Executive Officer & Director: Sure. All right. So I would say this, in terms of the way to think about our pricing philosophy, if you see us have double-digit market share for a reasonable period of time, then we'll look to take a pricing move. So the two contracts we have had double-digit market share. And it's important to note that we took a pricing move, and as I said, it was meaningful in that in May and June, from that pricing move we received $500,000 in gross revenue and our market share continued to increase. We're still a fraction of what the competitors charge. So there's room to grow there. And as our share continues to grow and we deliver more value to our customers, we're going to see that. So, as different assets get to that double-digit threshold, then we will think about that. It's also important to note that we're adding new instruments to the platform and I think we're very excited about that. There was a bit of publicity on that just the other day. So, that's going to continue to go forward. With respect to the drag on the second quarter, Ron, that was $0.02?
Ronald Hassen - Finance Controller & Senior Vice President, Principal Accounting Officer, NASDAQ OMX Group, Inc.: That was $0.02. Yep.
Robert Greifeld - Chief Executive Officer & Director: $0.02 for the quarter. And so, one of the best investments we could make. So, clearly, as we have more instruments at double-digit market share and we're charging, then that burn rate will decline.
