Sure, Jay. Let me maybe first off clarify the $0.12. I wouldn't relate $0.12 in retail to margins. I think as we called out in the third quarter, $0.07 of that $0.12 is related to integration expense as well as contract amortization from purchase accounting associated with StarTex and MX. And as you know, in purchase accounting, as those customer contracts roll off, that expense is felt most acutely in the front 4 to 6 quarters. So that's really what's driving that. And I'd remark on the margin degradation, the remaining $0.05 is really a year-over-year experience and I think, fair to say that in 2010 we were still benefiting from the phenomenon that I mentioned earlier whereby there had been reduced competition in the retail space and we had very attractive customer margins. This is just the very problematic roll-off of those higher margins, as well as the renewal of customers at lower margins in a low-volatility, low-price environment. With respect to what are the offsets to the $0.16, as well as the retail $0.12, as I mentioned, we have seen on a year-over-year basis just in the third quarter alone, we're seeing significant benefit from the contributions of our wholesale load serving structure products business. That in and of itself is a $0.36 year-over-year positive in the business. Obviously, we have the divestiture of our CEP assets, that's the upstream business, and as you know we've continued to make investments and will continue to develop and harvest those investments in the gas space as we're investing in a non-operating position with operators to both procure natural gas for our gas-fired generation, as well as we're developing distillates and oil that are helping fund some of the development of our properties. And then finally, if you look at the portfolio management, and we alluded to this in the presentation, if you look at the portfolio management's contributions in regions other than Texas, that has been and continues to be a very positive contributor offsetting in part the experience in Texas, and again, I think that just speaks to the importance geographically of being diverse and not overly weighted towards one region. As well as, obviously, as I mentioned before the importance of the diversity of marketing channels with which to focus on to the extent that competition increases in one area, you can divert resources from that area and apply to less competitive parts.
