Thank you, Sandra. Good morning, everyone, and thank you for your participation today. Let me take a few moments to update you on the status of our merger with Exelon. During the quarter, we focused on completing the required regulatory filings and commencing the integration planning process. To date, all material federal and state regulatory filings have been submitted including the S-4, which was filed with the SEC on June 27. In addition, the schedule for the Maryland PSC proceeding was released to the public on June 28. That proceeding is scheduled to conclude by January 5, 2012, within the 225 days allowed by statute. As we look ahead, we expect to complete a number of key milestones in the third and fourth quarters and receive approvals from various stakeholders continuing into the first quarter of 2012. Once the S-4 is effective, we will hold a meeting with our shareholders in the third quarter or early fourth quarter. I commend our employees for remaining focused on safety and our operating objectives as we advance towards the completion of our merger with Exelon to become the nation's #1 competitive energy provider with one of the industry's cleanest and lowest cost power generation fleets and one of the largest customer bases in the United States. Let's turn to Slide 6 where I'll provide an overview of our financial results. This morning, we are pleased to report second quarter adjusted earnings of $0.76 per share, which includes a mark-to-market timing gain of $0.11 per share. Excluding these mark-to-market timing gains, our adjusted earnings would have been $0.65 per share in excess of expected planned results for the quarter. Including one-time items, Constellation reported second quarter GAAP earnings of $0.49 per share. In the first half of 2011, we experienced severe weather and a tough competitive environment reflecting low power price volatility. In addition, given the impacts of higher than expected outage days at CENG and modest dilution in 2011 from recent acquisitions, we are reducing our guidance by $0.05 per share to $3.05 to $3.35 per share. Jack will discuss our second quarter results and earnings outlook in more detail later in the presentation. Our NewEnergy business continues to build on its integrated multiproduct energy supply and management strategy delivering solutions to new and existing customers. We further advanced this strategy by completing the acquisitions of 2 mass-market energy providers: MXenergy, a Connecticut-based supplier of electricity and natural gas to residential customers and businesses; and StarTex, a Houston-based supplier of electricity to residential customers and businesses. These acquisitions accelerate the growth of our mass-market business and enhance our ability to execute our strategy to provide trusted service and cost effective energy solutions to all customers. With these 2 purchases, NewEnergy now serves nearly 1 million residential and business customers. Within our Generation segment, we continue to focus on safety, reliability and operational efficiency. Of note, our recently acquired Boston Generating assets outperformed for the quarter as net generation from the plants exceeded our expected output. Lastly, our regulated utility BGE continues to serve its customers safely and reliably. Retail choice is thriving with 250,000 BGE residential electric customers enrolled, a fivefold increase from 2009 and almost 100,000 residential BGE gas customers shopping over 50% of BGE's total customers. Let's turn to Slide 7 for a review of our MX and StarTex acquisitions. We continue to expand our mass-market presence both organically and through acquisitions. In June, we launched our competitive residential supply business in Pennsylvania. During the quarter and through July, we also closed on the acquisitions of MXenergy, one of the 10 largest competitive residential energy suppliers in the United States with operations in 15 states; and StarTex, a retail electric provider with a solid foothold in Texas' active residential market. The combined residential acquisitions are expected to be modestly accretive in 2012 and more significantly accretive in 2013 and beyond. MXenergy and StarTex add to our scale in the mass-market segment, which is an important component of both our growth strategy and diversification strategy. These 2 acquisitions added approximately 640,000 residential customers and approximately 70,000 commercial and industrial customers to our portfolio, bringing our total to approximately 900,000 residential and 95,000 business customers. The acquisitions also bring an employee base that has received significant awards for excellence in customer service. The combined acquisitions provide us the tools to continue in effectively growing our platform in the competitive residential retail market where customers are increasingly choosing to purchase from a competitive supplier. Since 2008, we've seen the percent of residential customers who purchase their power from competitive suppliers increase dramatically. As an example, in 2008, approximately 3% of Maryland residential customers were buying power from a competitive supplier. Today, more than 15% of Maryland residential customers are purchasing energy from a competitive supplier. In Pennsylvania, almost 20% of the residential customers have switched. And in a handful of other states, more than 20% of customers are now shopping competitively. In the coming months, we see significant opportunities for further shopping in New Jersey, Ohio and Illinois. The transactions also complement our focus to cross-sell the products and services we offer to our customers. Many of these customers purchased solely power or gas representing a significant opportunity for us to sell both. We believe Constellation's focus on helping all customers manage their entire energy spend presents a strategy with unique long-term earnings potential. Importantly, our bundled commodity and service offerings are a key differentiator in an increasingly competitive marketplace. Another important aspect of these transactions is that they expand our residential market presence to include an additional 6 states in which we previously had no residential power or residential gas presence. This market diversity should help us manage exposure to regionally specific risks such as weather and commodity prices while positioning us to take advantage of headroom opportunities. This geographic diversity is particularly powerful when combined with the expected addition of Exelon's complementary baseload generation. Turning to Slide 8 for a review of recent environmental compliance developments. Although depressed power prices remain the primary driver of retirement decisions for older, less efficient coal plants that do not have environmental controls, the new series of EPA rules should accelerate and add to this retirement trend. The substantial environmental upgrades that Constellation has already completed at our PGM coal plants combined with our portfolio of clean, nuclear, renewable and combined cycle gas plants continue to position us well for compliance. On May 13, PGM posted the results of the RPM auction for the 2014-15 planning year. According to PGM, the price decrease in the MAAC region where we have nearly all of our coal capacity was mainly influenced by fewer line bottlenecks, lower demand and an increase in demand response. We see this as a temporary departure from the longer-term equilibrium. Our view of the long-term trend from this auction played out in the RTO rest of pool price where coal unit retirements and anticipated emission control costs contributed to higher capacity prices. Certainty of this trend increased with the EPA's July 7 release of the final Cross-State Air Pollution Rule, which will limit power generation emissions of SOx and NOx in 27 states. The final rule is more stringent than the 2010 proposal with tighter emission limits beginning in 2012 through 2014 adding to energy and capacity uplift. This should induce disadvantaged generators to retire older plants even both taking into account the subsequent 2015 implementation date for the EPA's final Air Toxics Rule. We believe EPA schedules for rule completion and for compliance are appropriate and feasible based on our own experience with available control technologies and installation timelines to make our own fleet cleaner because we already made investments in pollution controls and lower emitting generation plants. Constellation's fleet should benefit from the new and forthcoming EPA regulations as higher power and capacity prices more than offset any incremental costs of compliance. Turning to Slide 9, we'll review our efforts in innovation testing and strategic partnerships, another aspect of our approach to meeting our customers diverse energy needs. We are continually working to better engage the innovation community and leverage the power of newer, smaller companies to accelerate innovation through partnerships, collaborations and venture investing. This past June, we completed a strategic partnership with Astrum Solar, the largest residential solar installer on the East Coast. While we already developed solar power systems for commercial and industrial customers, we are seeing increased demand from our residential customers to add solar to their portfolio of energy solutions. Our relationship with Astrum provides us a platform to respond to that demand. This partnership highlights our commitment to introducing innovative technologies and solutions to make ourselves and our customers more competitive, enhance our brand and spur growth. Other examples of our external engagement with innovative companies include previous strategic partnerships with residential energy management provider, Consert; enterprise energy resource management solution provider, C3; and high-efficiency solar PV module developer, Alta Devices. Within the company, we have successfully developed and launched our own Constellation branded innovations including energy management technologies i2i and VirtuWatt. The combination of the new innovative technologies with our leading customer-centric commodity supply footprint creates comprehensive offerings which distinguish us in the marketplace. With that, let me turn the presentation over to Jack for the financial review. Jack?
