And we'll take our next question from Jamie Cook with Credit Suisse.
Jamie L. Cook - Credit Suisse Securities (USA) LLC (Broker): Hi. Good morning. I'm sorry. Good evening.
David Thomas Seaton - Chairman & Chief Executive Officer: Hey, Jamie.
Jamie L. Cook - Credit Suisse Securities (USA) LLC (Broker): David, on the projects in the EC&M business, I guess I'm still not comfortable. This sounds like an execution issue where these fixed price contracts, what percent complete are and why you feel comfortable there's not more to come. And Biggs, I guess my other question is, it doesn't – I'm having a hard time get your margin assumption in back half of the year, like what's changed in EC&M in terms of mix that would drive the margins that much lower. I have a hard time to just – I have a hard time believing there's – this is not related to some degree to these two projects.
David Thomas Seaton - Chairman & Chief Executive Officer: Well Jamie, the first part of your question, one of those projects has achieved mechanical completion and the other one is well down the road in construction. So I think – I feel pretty good about where we are on those two projects. I know you've heard me say that on other occasions, but we've really delved into some of the root cause. And in the...
Jamie L. Cook - Credit Suisse Securities (USA) LLC (Broker): Are they fixed price?
David Thomas Seaton - Chairman & Chief Executive Officer: Yes, they are. And in the second case, you have some significant weather events that impacted those projects. Those events are behind us, and we know what the effect was. And as I said, we're in negotiations with both customers to try to kind of retrieve some of that loss that we think we deserve, but it's where we are right now.
Jamie L. Cook - Credit Suisse Securities (USA) LLC (Broker): And can you tell us the dollar amount associated with what needs to be completed? And then, Biggs, again, there's got to be more than mix that's implied in the back half of the year on your margins in EC&M to get to your new margin forecast versus your old one?
David Thomas Seaton - Chairman & Chief Executive Officer: We're in the high 60% complete range on the other one.
Jamie L. Cook - Credit Suisse Securities (USA) LLC (Broker): Okay. And then, Biggs, I mean, just help me. The math doesn't make sense, and I'm also having a hard time figuring out the ramp in EPS in the back half of the year versus the first half of the year, how we get to the low end of your – even to the low end of your guidance. I mean, it implies in the back half of the year, we're at, I don't know, $0.90 versus the first half of the year, we've been at $0.70.
