So, if you just do the balances, you're adding about 50% ethylene capacity in the U.S. and it's along the U.S. Gulf Coast. So, do we see regional differences in netbacks in the future? We absolutely do. Because if you're going to run all these plants, you're going to need supplies from areas that have, what I'll call, stranded ethylene. Ethane, at the current time, so that ethane is going to have to have a strong price signal for producers to plan on drilling it, processing it and shipping it to the U.S. I think that's the bottom line. If ethane prices get too high, then we've said before that it's our anticipation that the merchant players are going to be, I'll call it the odd man out, because they don't have the value chain to produce polyethylene and the other derivatives. So, I hope that answers your question, Darren, but that's summarily how we see it.
Darren C. Horowitz - Raymond James & Associates, Inc.: It does, Tony. And I appreciate it. I'm just curious as a follow-up, and we expect it the same way. As you see, I think, more volatility in regional ethane frac spreads, we see a tremendous amount over the next 12 months to 18 months of arbitrage opportunity. And when you start talking about the value chain incremental equity NGL barrels to be produced, let's just say at a – the Piceance you went to, Meeker and those plants. How do you see the biggest regional margin capture opportunity? Is it Conway to Belvieu? Is it possibly Belvieu to South or even West Texas? Or maybe even more leverage, referencing an earlier question, on an arbitrage opportunity between the Marcellus and Utica in the Gulf Coast?
