And maybe you could address that because we are talking about this as if it's a painful medicine no one wants to take. But maybe you could give us some color on what it means for the speed of product fulfillment, inventory turns, those sorts of things, the reasons you're inherently making this investment.
David D. Petratis - Chairman, President & Chief Executive Officer: So, historically, we have led our industry in terms of inventory turns, cycle times and profit margin. We think modern tools, Windows-based tools on the floor will continue to give us differentiation on those factors. I think second, it's important that we look at the end customer. Why would I want a common system? I can't ship today on one invoice from our various manufacturing facilities. And customers want this. It's something I think over the long-term planning horizon we've got to plan for. Another dimension of the optics of lead time and the change management happened as we turned on the new system, I mean, clearly we've changed some things and are coming back quickly. But we closed the books financially at a faster pace than we had at any ops ever. I'd like to be able to spend less money on financial consolidation and more on analysis, analysis of our profitability, our customers. So, there's multi-dimensions in terms of these systems, but we'll hold them to a business case and we think we'll drive the things that are important to us: return on invested capital, high inventory turnover, and time.
Patrick S. Shannon - Chief Financial Officer & Senior Vice President: And, Jeff, so think about it also back office efficiency moving from multiple systems to one common platform. It just provides all kinds of efficiency, better control environment, et cetera, from a finance perspective, order management, so those type of activities, better customer service. So there's a whole spectrum of business benefits not just in the manufacturing floor.
David D. Petratis - Chairman, President & Chief Executive Officer: I want to add one other point in terms of benchmarking. As we look on our global IT cost, we're at the upper end of the range. And to get that to the benchmarks that we would like, we think we've got to upgrade these systems. And I'd share that just – this is how we think in terms of the overall performance of the business. We want superior capabilities, but we also want to make sure that the cost structure that deliver that is in line with other industrial companies.
