I think on the ethylene part, we're consuming over 1 billion pounds of ethylene as a company, in ethylene oxide and in other ethylene derivatives, and of course we consume a great deal of propylene as well, Bob. So, we are going to be subject to the cyclicality of those raw material costs one way or the other. The ethylene production that we have internally is about 400 million pounds of that billion-plus pounds of consumption that we have. It's low-cost production, ethane-fed production, and I think should that ever not be profitable to us, we certainly can shut that smaller unit down, as we have in years past. But while it continues to generate margin uplift and improvement for us, we'll continue to operate that facility. I don't see that really as a massive flywheel on the overall cyclicality and profitability of the company. On the MTBE side, if there was some way that you could look at MTBE, it's just a stand-alone facility that was out from the rest of our portfolio. I think that we probably would have some more options there. But, Bob, as you know, that's a facility that produces MTBE as a by-product of propylene oxide. And I think we've tried to be, particularly starting about a year ago, as transparent as we could, educating investors as to what are the components of volatility there and what drives the MTBE markets. As tough as MTBE looks, as we look at this on a combined propylene oxide MTBE sort of a basis, I expect this year that our EBITDA margins in that PO/MTBE combined business is going to be around somewhere in the mid-teens of an EBITDA to sales. So, as we look at that I would just remind you that when we look at MTBE, if you take that and you put it in with the propylene oxide, the downstream advantage that propylene oxide adds to the Polyurethanes business, I think it probably doesn't provide quite the volatility that it would appear when you break it out. But, nevertheless, as you compare it to where we were a year ago, it is a volatile component of our earnings.
Robert Andrew Koort - Goldman Sachs & Co.: And then, Peter, if I might follow up. I don't believe I heard on MDI you talk about the opportunistic margins you might be making in the short run from some competitor problems. Is that just being diplomatic, or is that something you guys won't realize from a short-term basis?
