Thank you, Nahla and good morning everyone. I am joined here today as usual by Bob Flexon, our company's Chief Financial Officer; Kevin Howell, Head of Commercial Operations; Drew Murphy, our General Counsel, Krishnan Kasiviswanathan, our Chief Risk Officer, John Ragan, our Northeast President. Northeast region had a phenomenal year last year and for reasons that should be obvious from anyone who has read the earnings release by Clint Freeland and Maurizio Guacharo. This is the call... first call of the year where we normally set the stage for the year ahead and we are going to do some of that. We're also going to talk about the changes in the orientation that were announced in the press release today, because they are a little bit out of the ordinary, but as I said in the press release today. These are evolutionary changes rather than revolutionary changes in the way that company is organized and this is actually the end of an organizational process rather than the beginning and that these changes were determined and decided upon last July and we've been working through to this conclusion today. So, I am going to be referring as we go through the presentation to slides which appear on the website and I'll be referring to those. So, stay on slide three, table of content. Actually after 15 quarters of using the same format in the last few quarters, we have actually not even had a table of content, so our only remark now is that this is actually the orientational format that we will be using going forward. I will be giving the operational review this quarter but in subsequent quarters it will be given by Bob Flexon and so lets begin. On slide 4, since we have a lot of information to go over today as always and there is a lot of information on our earnings release, I want to fly for you the three things that I think are most important about today's announcement. First, with respect to the company's full year 2007 financial performance, to me the key number is $1.25 billion, that's our free cash flow results before special environmental projects and growth CapEx. This healthy result which exceeds our guidance meets directly to the double-digit free cash flow yield, which you can find tabulated in Bob's section of the presentation and which remains the fundamental investment proposition of this company. I have said on these calls and in many one-on-one meetings in the past, we managed this business for cash and this result proves that 2007 was no exception. Second, while our company has adopted a slightly more conservative posture with respect to our liquidity in light of the current capital market environment, we have never been more strongly positioned both from the point of view of our current liquidity and in terms of how we collateralize our commercial operations activities. Perhaps, more importantly the current capital market environment has not effected our commitment, which we first made approximately one year ago to return to our shareholders on an annual basis at least 3% of our market cap either by way of a share buyback or through common stock dividend. And indeed, we are disclosing today that we have already begun the share buyback program for 2008 having repurchased $100 million worth of our shares in the last few months, of course, prior to entering the current close period. And third, while the development process for new power plants particularly those involving new technologies remains very lengthy, we made meaningful progress across almost all of our development efforts in 2007 and we are positioned to put further distance between us and our competitors in this area in 2008. Moving to slide 5, in 2007 you can see some of the highlights of how we executed across our major areas of day-to-day business. I can't go over all of these because of time, but would like to highlight a couple of items. First of all, in terms of asset sales, as we have always told you we are always looking to optimize our asset portfolio both core and non-core. With respect to non-core assets, our record has been to act deliberately to ensure that we realize maximum value and that has worked for us through more than 20 asset disposals which we have carried out over the last four years. Almost all of which have exceeded market expectations in terms of sales proceeds. This is the approach we have taken with respect to our Brazilian project, ITISA in recent months. We have a binding sales agreement for $288 million and we expect when that project closes to be able to repatriate to the United States about $250 million net cash. The project is not yet closed, we expect it to close by the end of second quarter. Not all approvals have been obtained yet but we are confident as to what has been obtained, that there is no obstacle that we see to closing out this transaction. With respect to safety, NRG ended 2007 with an initial recordable injury rate of 1.6 to the 20% improvement and well beyond the 2006 industry average of 3.9. This is an important milestone for our company because 1.6 processing the top quartile within the power industry. This great result was achieved only by an all hands on deck effort at all NRG locations and at all levels of the organization. I want to commend everyone at NRG for their contribution to this result and I want to particularly commend the plans that either are participating in the OSHA Voluntary Protection Program at this time or are going through the lengthy application process now. In terms of plant operations, there was an equally broad and deep level of accomplishment across our fleet. So, again I can only note a couple of the two highlights. The first is that we contributed mildly to keeping the lights on in Southern California, first through our timely completion of the emergency repowering of the Long Beach plant in time to support included during the late summer heat waves, where the plants made 36 starts with 99% of reliability. And secondly during the late fall California wildfires, which disrupted transmission in the San Diego County forcing the Carlisle to rely totally on the very limited in county generation like ours to keep the lights on. Similarly in New York City our Arthur Kill plant was repeatedly dispatched as a mail order. So much so that the energy production for the year was up 97% and the plant responded with admirable reliability. The other highlight that I want to mention was our South Texas nuclear plant. At this point, everyone knows that we've applied to build a new nuclear plant at STP, STP 3 and 4. But quite distinct from that effort is the exceptional work the STP operating team has done with STP 1 and 2. I could recite the numerous operational words that this plant received in 2007 but suffice it to say that for the year STP was again the top generating two unit sites in the United States. These special performances feed in to the fleet performance statistics which appear on page 6. Although, our 2007 base load equivalent for solid rate performance was down year-on-year, it remained much better than two years ago. I don't intend to try and explain this result away to you because as a company which bases it's operations on a philosophy of continuous improvement, we are not happy they have taken a step backward from 2006 to 2007. And we hope and expect to change the direction of this bar chart in 2008. However, there are two significant mitigating factors. The first is that only four out of the 20 operating core units in our fleet had a preponderance of the unsatisfactory E-4 performance. This allows us to concentrate our focus on those units as we troubleshoot the problems. The second mitigating factor is as demonstrated in the upper left, one of our principal for NRG objectives was to capture nameplate base load capacity. And our achievements in this area had a positive impact that exceeded the impact of the incrementally higher E-4 rates. Despite the E-4 results our total fleet generation was up year-on-year. The substantial increase in production in STP I already mentioned is noteworthy, but also there is the enormous decrease in energy sales from our Texas gas plants. This has nothing to do with the reliability of those plants, but was a result of the extraordinarily wet and mild summer in Texas last year. We expect our Texas gas unit to do much better in 2008 assuming normalized summer weather. And finally, on this slide I want to talk a bit about our coal inventory because I know that the coal world is abuzz with red hot coal pricing that people are telling you will last forever. As you can see from this chart, our aggregate inventory levels stand at approximately 45 days as of the end of January. We opportunistically increased our inventory prior to the current run up in coal prices. And if you now turn over to slide 7, you will see our total fuel position longer term, 100% contracted for 2008, 93% for 2009, 64% for 2010, and so on. And please keep in mind as you consider our exposure to higher coal pricing that Eastern Coal represents only a fraction of the coal that we consume. It is so little in fact that less than 1 million tons a year of Eastern Coal that we use is subsumed in this table on the lower right in the category labeled other. The other important point, you need to understand about NRG and coal consumption is that even among Powder River Basin coals NRG uses much more 8,400 BTU coal than 8,800 coal. And 8,400 BTU coal is even less suited to the international on the Eastern Coal markets than the 8,800, and has resulted and subject to considerably less pricing pressure in recent months. The other point I want to make on slide 7 is actually about the non-event. You will note if you compare our hedging chart on the left to the one that we showed last quarter there has been essentially no change in our hedging profile. This means that it's been almost a year since we engaged in significant additional hedging activity, and to me that is the beauty of our strategy. We can sit out the market when gas and storage is high and gas price volatility is low as they both have been and as such we consider ourselves a patient ball waiting for the time when strong fundamentals and weather push gas prices above our targets enabling us to lock in long-term prices at favorable levels. On slide 8, this slide goes hand in hand with the prior hedging slide and again, there is very little change. We've the fundamental short-to-medium term risk posture that we think provides the best risk adjusted return to our shareholders, low-to-moderate gas price sensitivity over the next few years and much greater exposure to increases and base load heat waves. Now turning to slide 9, I want to highlight one another benefit of our hedging strategy which is highly topical at this point in time. We run sensitivities of our earnings general economic recession using the 1990 recession as our guide because we think that recession is more similar to what the country is facing now. But, on the assumption that the expected recession that we face now would be significantly longer and harder than the one that occurred in 1990. On these assumptions, the negative impact on our 2008 EBITDA would be significantly less than 1% of the total. I also want to point out that, you know, while not being an economist or an expert on these things, I ask the question, how much of the recession we'll face in two of our core regions, Texas and Louisiana with crude oil prices hovering at a $100 per barrel even if there is a national recession? But all the same, impact on us less than 1% of our EBITDA in 2008. As such, I think it's fair to say that while NRG may not be recession proved, we are highly recession resistant. These discussions are merits of our hedging strategy over the past few slides provides an appropriate point of departure for me to discuss the management changes that are being announced today. I am firmly convinced that this company and you as shareholders have benefited enormously from the hedging strategy including the hedge reset of November 2006, which was implemented by our commercial operations group over the past three years. While speaking on these quarterly calls and otherwise and to investors and one-on-ones in that industry conferences we generally have not sought to feature the invaluable role played by our comm ops team in the success of this company. We have kept a low key because comm ops generally doesn't like to give any signals to the market as to what they are thinking and also a little bit more selfishly for reasons of human resource retention we don't like to flaunt to the market how good our team is. So, when we board that tact to go wider and basically say that NRG has the most capable asset base trading and marketing team in the business. And the person who has built that team and led it to considerable success that it and we have achieved is Kevin Howell. What has also impressed me in working with Kevin over the past three years is not only what he and his team has achieved but also how they have achieved it. As AEP and others found out several years ago, there is considerable challenging grafting or developing a hyper aggressive and self interested trading and marketing team on top of it generating asset base and a power plant company culture. Kevin has built a team that functions effectively and pretty much harmoniously along side our plant operations. This has taken a Gus touch with respect to personnel both his own team and his colleagues and Senior Management. I can say I have learned more about personnel management from Kevin Howell then I have from any other single person in my entire career. It is these management qualities that cause me to ask Kevin to take on the role of Chief Administrative Officer. A post from which he will be responsible for ensuring that NRG has all the capabilities that we need both in terms of software and by that I actually mean the right people and hardware to realize all the extraordinary opportunities that currently are presented to us in our marketplace. With Kevin in-charge I am confident that we will have the tools that we need to achieve our destiny as a company. Now before I see the floor to Bob Flexon for his 16th and last quarterly turn as the Chief Financial Officer of NRG Energy, I want to take a quick look back of what has been accomplished on his watch. I could think of no more fitting testament to Bob Flexon then as you might say to go to the numbers. Slide 10 attempts through a long series of financial metrics to show that financial strength of this company at the time of Bob's arrival in early 2004 and where we are now. I know of no other Chief Financial Officer certainly not in this industry who have achieved so much starting with so little in such a short time as Bob Flexon. Now reassuringly large numbers, you on the phone have been with us since the beginning and have witnessed the financial strengthening of this company over the past four years. I know you don't need to be convinced of what Bob Flexon has accomplished with this company and this balance sheet. And he assures me that the company's progress in this area has been so obvious that there are only three people in the whole financial world who don't get it. Unfortunately as you can tell from the bottom at this page, those three people are named Mr. Standard, Mr. Poors and Mr. Moody's. When I think that we have one major rating agency that has not acknowledged any improvement in our financial conditions since our inception and we have another major rating agency that has had us on negative outlook for 14 months notwithstanding our $2.7 billion of current liquidity, I am literally at a loss for words. But maybe my speechlessness is a function of what my daddy used to say, David, he would say, never try to rationalize the irrational, never try to defend the indefensible. Anyway trying to get back on the high road here, it's been my immense honor and pleasure to work with Kevin and Bob in their current positions as they are Head of Commercial Operations and CFO respectively and I look forward with great anticipation to working with them in their new positions as Chief Administrative Officer and Chief Operating Officer. Now I know, I probably should say something at this point in time about Clint and Maurizio only because they are both sitting here at this room looking at me. But rather than sing their praises now I would rather do that after they prove themselves to you the owners of this company. But I would say that they have been a big part working with their teams and with their extremely capable colleagues, they have been a big part of this success for this company today. And suffice it to say that the three of us, Kevin, Bob and myself have total confidence that they will succeed in their new positions and they have our full support. So, with that I'll turn it over to Bob Flexon.
