Thank you Chris, and good morning, everyone. My remarks today will cover our first quarter results, an overview of our current rate cases, an update of our gross margin disclosures and a review of some of the events that occurred this quarter. Turning to slide 8, we had a strong quarter financially and operationally across the company. For the first quarter we delivered adjusted non-GAAP operating earnings of $0.65 per share, at the top of our guidance range of $0.55 to $0.65 per share. This compares to $0.68 per share for the first quarter of 2016. Exelon’s utilities delivered a combined $0.47 per share versus our plant and utility results were impacted by unfavorable weather at PECO and PHI which was more than offset by O&M timing across all the utilities. With 70% of our distribution rate base and decoupled jurisdictions including ComEd starting in 2017, we experienced less volatility on our utility earnings from record warm weather in January and February than if we did not have these programs. To help put this winter in context, this was the first time in 146 years when there was no snow on the ground at Chicago for both January and February. Looking across PJM, January and February was the warmest on record since data started being collected in 1950. Generation had a strong quarter relative to plan earning $0.18 per share. We had good performance from our nuclear assets with better capacity factors than budgeted and our constellation team once again delivered strong results despite weak power prices and low volatility. Turning to slide 9. The $0.65 per share in the first quarter of this year was $0.03 per share lower than the first quarter of 2016. To the positive, we had a full quarter of contribution from PHI relative to only 8 days last year, which added $0.09. The other utilities benefitted from rate relief and higher rate base, partly offset at PECO with even milder weather than last year. ExGen was down year-over-year primarily on the loan impacts of lower capacity prices and power price realization as well as more planned refueling outages. Turning to slide 10, we are reaffirming our full year guidance in this range of $2.50 to $2.80 per share. We expect to deliver operating earnings of $0.45 to $0.55 in the second quarter compared with $0.65 last year. Our second quarter results will include contributions from the FitzPatrick plants and the plants of the New York ZEC program that started on April 1. The Illinois ZEC legislation will go into effect on June 1, and plant procurement is expected to occur later this fall. Plants receiving contracts with recognized revenues retroactive the June 1st effective date. Moving to slide 11. Our utilities continue to execute well delivering strong earned returns in the quarter. Looking at the trailing 12-month booked ROEs we saw nice improvements even relative to what we showed last quarter. At PHI we saw all of the utilities registered gains with some that are coming as revenues from the first cycle of rate cases are starting to flow through to results. For the Legacy Exelon utilities we continue to see strong earned ROEs over 10% that led the consolidated Exelon’s utilities platform to nearly 10% including PHI. We have plenty of work to do at Utilities and with our regulators to keep improving the product we are delivering to our customers, but we are happy with where the overall business is performing. We are obviously pleased with where our earned ROEs are trending, but I want to remind you that there will be variability in the earned ROEs that are different utilities as we go forward. The timing of rate case implementation, weather comparability and in-service states were all at back results. We think the ability to earn strong ROEs and the plan that we had in plan at PHI they improved their ROEs will be the recipe for our future success. On slide 12 we have an update on our rate cases. Since our fourth quarter call, we have closed out the Delmarva Maryland case with a revenue increase of $38 million. We’ve also reached unanimous settlement in our Delmarva Delaware Electric and gas cases for $31.5 million and $4.9 million respectively and would expect commission approval during the second quarter. From our first cycle of planned rate cases we are now down just to the Pepco DC case but we expect the commission decision later in July. We are proud of the hard work from our utilities and regulatory teams, these efforts are helping to get PHI’s revenues and earned book ROEs back on course while we simultaneously improve performance for our customers. As we have shared with you many times before, we’ve always viewed the turnaround in PHI earned ROEs as a – rate case cycle process. To that end, we filed our second rate cases in ACE and Pepco Maryland this quarter. Combined with the outstanding cases from the first cycle that I previously mentioned we are currently asking for $252 million in revenues which reflect recovery on multiple years of capital investments that have been made to improve the reliability of the grid across these jurisdictions. We expect the final ruling on Pepco Maryland and ACE likely in Q4, 2017 and first quarter of 2018 respectively. We plan to file a second cycle of cases in most if not all of PHI’s jurisdictions in 2017 with all completed by the end of 2018 putting us in a position to earn between 9% and 10% ROEs in 2019. More details on the rate cases and the schedules to be found on slide 29 through 36 in the appendix. Slide 13, provides our gross margin update for ExGen. In 2017, total gross margin is flat to our last disclosure. During the quarter, we executed on $150 million of Power New Business and $50 million of Non-Power New Business. We are highly hedged for the rest of this year and have fell down -- generation to load matching strategy. Total gross margin decreased in the first quarter by $50 million in both 2018 and 2019 due to the impact of price changes on our order portfolio. We ended the quarter approximately 12% to 15% behind our ratable hedging program in 2018 an 8% to 11% behind ratable in 2019 when considering cross commodity hedges. The majority of our length is concentrated in the Midwest to align to our view of spot market upside at [Nine]. Although we have increased our lengths in other regions as well. We are comfortable to be more open when we look at market fundamentals. For example, oil regional natural gas prices today are over a $1 per MMbtu higher than they realized last year, yet the forwards for power are only about $1 per megawatt higher. We do not believe that is a sustainable situation. To that point I should note that power prices have risen since the start of the second quarter and have reversed about half of the first quarter price declines. On slide 14 we have highlighted some key recent events. On March 31, 2017 we executed on the creation of the Exelon Generation renewable JV, which will provide us with $400 million of pretax cash, including allocated debt that puts total JV Enterprise value at approximately $1.7 billion, the price implies an EV to EBITDA multiple over ten times and $1 per – [KW] value over $1,200. The JV consists of 1,296 megawatts of renewable generation capacity which is about 35% of our renewable output and has an average contract life of 14 years. The JV structure provides the option to drop down contracted renewable assets from our portfolio in the future. The proceeds from this sale will be used to accelerate our deleveraging strategy. Also on March 31, we closed on the acquisition of the FitzPatrick nuclear station from Entergy which adds 838 megawatts of nuclear capacity to our portfolio. The FitzPatrick plant is part of the New York ZEC program and will receive ZEC payments for the next 12 years which started on April 1. The plant is now operated by Exelon and I am happy to report we had a clean cut over of FitzPatrick onto the Exelon platform. We are excited to have the FitzPatrick employees as part of the Exelon family. Our Exelon generation Texas partnership, commonly referred to as EGTP is a portfolio of 3,476 megawatts of gas generation in Texas. In 2014, we raised $675 million of non-recourse project finance for the assets which currently has a balance of approximately $650 million. With a downturn in ERCOT power markets these assets have been under pressure with a debt rating at a discount of base value for some time and the plant is struggling to generate adequate cash flows. Due to the combination of challenge cash flows and our decision not to inject additional equity we have come to terms with the lenders to pursue an orderly sale of the assets on their... The modest current earnings and all of the debt are still included in our financial outlook. However, we see the ultimate exit from these assets being accretive to our UPS] and debt to EBITDA multiples starting in 2018. In light of the process we are not in a position to expand further out in this transaction. Finally during the quarter, we decided to discontinue the sales process of Mystic 8&9 assets. We were exploring a sale of these assets as a direct result of interest received from potential buyers. During the sales process we ran into some issues with the fuel supply agreement that needs to be addressed. And as we said we would only transact if we were to realize a price greater than our – value. Our continuing to own these assets does not impact our commitments on our debt-to-EBTIDA target and debt reduction plans that we’ve already shared with you. Turning to slide 15, we remain committed to maintaining a strong balance sheet in our investment grade credit rating. We are forecasting to be a 3.2 times net-to-EBITDA at ExGen by the end of 2017 and have a clear path to our long term target of three times debt-to-EBITDA. On a recourse debt basis, we are already well ahead of our target and taking into account the sale of EGTP we would be on target overall. As we said before we will look to [Indiscernible] whole project once we have reached three times target at ExGen. I’ll now turn the call back to Chris for his closing remarks.
