Yeah. I just had a question on capital allocation, Theresa, approaching $800 million in cash right now. Your debt maturities are pretty well laddered, CapEx under control. Any thoughts on what the hierarchy of capital allocation is at this point, and how we should be thinking about deployment? Thanks.
Theresa E. Wagler - Chief Financial Officer & Executive Vice President: Well, I think from the team's perspective, and Mark can kick me under the table if he disagrees, but growth, we believe, is still going to drive the greatest value to the shareholder, and so, especially in this environment when things are pretty weak for our peers, to wait and watch to see what assets might become available. And then also on the organic side, we mentioned several projects where we have extra melting capacity that we want to utilize. So that tends to be very capital efficient. So I think that's our primary focus. And then obviously, we have the positive dividend profile. We have additional, potential debt reduction which you're right, the maturity ladder is really flexible for us from the long-term great rate perspective. But we evaluate all different aspects of returning value to shareholders. But I would say that's the hierarchy. Mark, do you agree?
Mark D. Millett - President, Chief Executive Officer & Director: Yeah. Totally. We continually assess options. I would tell you that the current environment is certainly unique, I think, in most of our short lifespan as an industry. But it's going to be an interesting year, interesting 18 months. And I think it's a case of a good time to keep one's gunpowder dry. Be patient, because I think there's going to be – there are already tremendous opportunities – tremendous, I take that back. There are already a myriad of opportunities coming to market. And I think the focus needs to be being prudent and patient, and waiting for those opportunities that will really, really improve our margin profile and not just take the first thing that comes down the road, so to speak.
