David A. Zapico - AMETEK, Inc.
Management
Yeah. We haven't talked about 2018 yet. But certainly, we've already booked some orders for 2018, those large projects in the Middle East that I talked about two quarters in a row. And we think the price of oil in that $45 to $50 range is fine. It allows us to – we have very differentiated products. We have a captive aftermarket. That aftermarket's about one-third of the business. The business is geographically dispersed, about one-third in the U.S., two-thirds international. And during the downturn, we continued to invest in our market position. So, we feel really good about it. We're not expecting it to turn into the gung ho times of the past. At that time, it was about $400 million in revenue for AMETEK, and now it's about $240 million in sales entering 2017. So, it's about 6% of the company; 20% upstream, 80% mid, downstream. So, 20% upstream, 80% in mid, downstream. And at the current price of oil, we're seeing increased activities. So, customers are talking to us about orders. They have capital spend. The authority to spend is back in the business units, instead of the C-suite. And we had some modest expectations coming into the year, and we feel solid that we're going to achieve them or beat them.
Robert Paul McCarthy - Stifel, Nicolaus & Co., Inc.: And then just the last more of an editorial comment. I mean, have you looked at the potentially – a lot of your competitors have moved – or not competitors, but public comparables, I suppose, have moved to looking at kind of cash earnings, just given the nature of their business models and the compounding kind of the M&A business model, which is similar to yours, obviously. Have you looked at that? And just in the context of just your strong operating and free cash flow generation?
