Our next question comes from Rich Tullo from Albert Fried & Co. Please go ahead with your question.
Rich R. Tullo - Albert Fried & Co. LLC: Hey, guys. Congratulations, a very fine quarter, and thank you for taking my question. As we look at this deleverage, how should we be thinking about the parameters of the deleverage? I mean, is this going to be more of a factor of the growth in EBITDA or are you going to divert more of the cash generated from working capital as well as the free cash flow of the company? Is that more going to be directed at paying down actual debt? And then as an aside, is the dividend policy going to be reflected anywhere, influenced anywhere in all that?
David B. Doft - CFO, CAO & Head-Investor Relations: Thank you, Rich. So the deleveraging will come – our expectation is from growing EBITDA, not from paying down debt. We're big believers on maintaining maximum liquidity especially in terms of potential volatile economic cycles and we've been in this economic expansion now for a few years. So we surely don't want to be looking to reduce our liquidity now. And so we're looking to EBITDA growth. And I just want to remind people that, the contingent obligations we talk about from deferred acquisition consideration are contingent on certain performance. And so, our expectation is that those businesses will generate the cash based on their performance to fund those earnouts. At the same time, if they underperform, those earnouts will come down and those businesses will still generate the cash to fund those earnouts. So from our standpoint, we like to keep the liquidity. It allows us to fund the growth of the business as well as the obligations going forward. And the underlying deleveraging will come as the EBITDA grows and the assumption with the estimated earnout is that EBITDA grows.
Rich R. Tullo - Albert Fried & Co. LLC: A second question, if I might, we've been contemplating FX headwinds under certain circumstances as being flat to actually a tailwind in 2016. If that were the case, how would you deploy the 150 bps to 200 bps of incremental revenue and possible incremental cash flow generated by a more favorable FX environment?
David B. Doft - CFO, CAO & Head-Investor Relations: Well, that's not a huge amount of money at the end of the day, so I don't think there'll be any special deployment we keep in mind. Hopefully, it'll lead us to beat expectations if that were the case. I hope you're correct on the FX environment. I think surely that'll be good for our numbers. But personally, I'd be a little surprised given that our FX exposure is predominantly Canada which continues to, I think, suffer from an economic standpoint from low oil prices and, thus, less demand for its currency.
Rich R. Tullo - Albert Fried & Co. LLC: Thank you very much.
