Thanks, John and good morning, everybody. As you've seen from our earnings release, Spectra Energy delivered second quarter ongoing results of $215 million or $0.33 per share. Like many in the sector, we felt the effects of weak commodity prices which were much lower than our original assumptions. Our Field Services segment experienced the most significant impact. However, lower propane prices also adversely affected our Empress plants in Western Canada. It was definitely a tough quarter for commodity prices. NGL prices dropped almost 40% from 2011. NYMEX natural gas average almost 50% lower and prices were weakened by a lower demand caused by petchem outages, slower economic conditions, record warm winter weather and exceptionally dry summer affecting crop drying expectations. Recently, we have seen an uptick in commodity prices off the low point about 6 weeks ago. But I think it's fair to say that it would take an extraordinary increase in NGL prices for the rest of the 2012 to be at the average level we projected at the begin of the year. Pat will provide more details around our commodity price expectations in just a few minutes but given the current and near-term commodity price environment, it's very unlikely we'll realize our $1.90 earnings per share target for 2012. Now that said, looking beyond the quarter to the longer-term, the NGL fundamentals remain very positive for our business. Crude oil remains expensive relative to NGLs, new demand sources on the petrochemical front are set to come into service mid-decade. The infrastructure bottlenecks that restrict our volumes and Conway pricing relative to Mont Belvieu should dissipate over the next 12 to 18 months. In addition, propane should benefit from new export facilities starting late this year and early next. And we'll then have to assume that the abnormally warm winters and dry summers we've experienced are just that abnormal. All of these supports the long-term growth of the NGL business in North America and as a large producer of NGLs in the U.S., bodes very well for Spectra Energy's NGL business. Importantly, our fee-based businesses continue to perform in line with our expectations, and our expansion opportunities remains strong and growing. And as we projected at the beginning of the year, we saw increased earnings from expansion projects at U.S. Transmission, Western Canada and Field Services during the second quarter. Our consistent fee-based earnings allowed us to deliver predictable steady dividend growth, regardless of the commodity cycles. And as we have indicated previously, we remain very confident in our ability to deliver at least an $0.08 increase in our annual dividend over the next several years. In support of our growing dividend, we've had a solid roster of expansion projects, those are now in execution. They include about $4 billion in Spectra Energy-financed projects and more than $4 billion of DCP-financed expansion projects. We also have a robust pipeline of development projects providing additional opportunities to create ongoing shareholder value. All of these underlines our expectations of investing up to $20 billion through the end of the decade. In the near term, our 2012 to '14 expansion projects are in execution and on track. And we're starting to see the benefits of projects going into service. I'll highlight a few of these. In Western Canada, we're in the homestretch to complete about $1.5 billion Horn River Montney investment program, a series of strategic expansion projects. The first phase of the Dawson processing plant is now in service, and construction of Phase 2 is underway and expected to be completed by early 2013. The T-North pipeline expansion project provides additional takeaway capacity from the Horn River and Montney areas, and is supported by long-term firm contracts with shippers. This project went into service in the second quarter. And our final project in this investment program is the Fort Nelson North plant, which we expect to go online late this year. Also on track to go on to service in late 2012 is our $200 million TEAM 2012 project, designed to move Marcellus supplies from South Western Pennsylvania to markets in the Northeast. The project's fully subscribed by Range Resources and Chesapeake Utilities. And the next phase of our team project is the TEAM 2014 project. We've reached binding agreements with 2 anchor shippers, Chevron and EQT, for the project's full capacity. And we submitted our FERC prefiling in July. We expect to begin construction in early 2014 for the targeted in-service date of late 2014. Last month, we started construction on the New Jersey - New York expansion project, having received FERC approval in late June. And when this $1.2 billion project goes into service in the fourth quarter of 2013, it will provide much needed gas supply in economic benefits to the region. It will also create future opportunities for us in the area and annual EBITDA of about $110 million. A smaller project that you might not be aware of is the Thunder Bay project, which will serve an Ontario power plant being converted from coal to gas. This project is actually the first of an expected $300 million to $400 million slate of opportunities to capture continued power generation conversions in Ontario. And as we earlier -- as we said earlier, DCP Midstream is moving forward with more than $4 billion of projects in execution, producing fee-based earnings growth by quadrupling its NGL pipeline capacity. DCP is making excellent progress on 2 major NGL pipeline projects, Sand Hills and Southern Hills. The Sand Hills Pipeline is designed to provide NGL transportation from the Permian basin and Eagle Ford shale region to the Gulf Coast. They'll be phased into service, with the first phase about 65% complete already and scheduled to be in service from Eagle Ford to the Mont Belvieu area later this year. Right away, acquisition of material sourcing is substantially complete for the second phase from the Permian, which has a targeted in-service date of the second half of 2013. Southern Hills, which you'll recall will provide NGL transportation from the Midcontinent to Mont Belvieu has a targeted in-service date of mid-'13. Rehabilitation work on the existing pipeline, which we purchased from ConocoPhillips in the fourth quarter 2011 is nearing completion, and construction of more than 300 miles of new pipelines has been initiated. In addition to these NGL pipeline projects, DCP is also building and expanding a number of gas processing plants. It recently broke ground on 3 of these projects. The expansion of the National Helium Plant in the Midcon. The LaSalle Plant, which will provide service to producers in the DJ Basin. And the Rawhide processing plant that will serve producers focused on the Wolfberry production in the West Texas region of the Permian. As a reminder, DCP self-funds its own growth, which of course is advantageous to Spectra Energy and its investors. As mentioned earlier, with our expansion projects and our development plans on the horizon, we see more than $20 billion in expansion projects and opportunities through the end of the decade. In U.S. Transmission, we're pursuing $5 billion to $8 billion in development opportunities, many of them including NEXT, OPEN, AIM and Renaissance will connect from Marcellus and Utica suppliers to diverse North American markets, including the Midwest power market, premium Northeast and New England markets, LDCs and power generators in Eastern Canada, and gas and electric utilities in the Southeast U.S. And we've got other opportunities across their system as well. In Western Canada, we see about $4 billion to $6 billion in expansion projects through the decade. We're continuing to pursue opportunities around LNG exports and in fact, we're in advanced negotiations to provide pipeline infrastructure to support the development of British Colombia LNG export projects. And DCP Midstream has another $2 billion to $3 billion in the development opportunities, primarily in gathering and processing in NGL infrastructure. So as you can see, our business plan and strategy remains solidly on track. We're expanding our impressive portfolio of assets and we're continuing to demonstrate our commitment and capacity in all fronts, through our various commodity and base business cycles. Rewarding investors with steady, reliable dividend growth. So with that, let me turn things over to Pat, who will take you through our second quarter financial performance before we take your questions.
