Thanks, Mark and I'm on Page 10 and then I'll be on Page 11. I'm going to talk a little bit about backlog and what's going on in the markets. bidding activity was and continuous to remain active and it translated into a book-to-bill of 1.06%. Total backlog at the end of March is $3.74 billion that's up $369 million or approximately 11% from March, 2014. As I mentioned earlier, we saw backlogs that was sequentially also of $102 million reporting a strong book-to-bill reality, we should have a little less sequential growth of backlog because we should have burnt more revenue in the first quarter and our backlog driven businesses which is mainly our domestic construction businesses. In fact, if you look at our $3.7 billion of backlog, you'd have to go all the way back to 2008 to see a comparable period in the timeframe that we have outlined on this chart. And you can see that the gold portion which is commercial represents 34% of that backlog. Now if you take commercial and hospitality together in 2008 and you take that together today. You will see that we have the same level of mix of that work and in 2008; we were still working through the last phases of the Las Vegas expansion. Commercial sector backlog is close to $1.3 billion, an increase of $185 million or 17% from March, 2014. This really now two year to three year momentum in the commercial market gives us some confidence in conviction and it continue to pace of the non-residential recovery that we will see growth this year, despite the tough first quarter. As I mentioned earlier, the quarter's booking activity was strong and dispersed among many market sectors from December 14 in commercial and institutional and believe it or not, a little bit in hospitality. We also saw it in industrial which for us also includes manufacturing and water and wastewater. We did burn a little backlog in healthcare and we think this is a sector that's not going to see a lot of growth although we have a some decent opportunities in front of us in specific markets. the people are still sorting; our customers are still sorting through the ramifications of the Affordable Care Act. Transportation backlog decreased a bit, but we still have some very good infrastructure projects that not only we're working on, but that we also are bidding on. From a year-over-year perspective, our backlog growth has been fuelled by increases in most market sectors. Led by substantial increases in both commercial and transportation, but we're also seeing increases in industrial/manufacturing water and wastewater and yes then we'll jump in hospitality. As you can see our backlog from a market perspective is anchored in the commercial sector, we do well there and is balanced throughout the remaining sectors. A good position to be in and many people do think, we have a growing non-residential mark in 2015 and we believe that too. Looking at it by segment, mechanical and electrical construction segments both grew backlog year-over-year and from 2014 and together these segments comprise EMCOR Construction Services. EMCOR Construction Services backlog which represents our mechanical and electrical segments stands at over $2.7 billion, an increase of $414 million over March, 2014 an increase of $89 million over the December, 2014 level. Again, I wish we would have burned some of the backlog in the first quarter and drive the resulting earnings from it. Well you see the construction of that and you can see the substantial segment growth year-over-year. Mechanical up 15% and electrical up 22%. Building services is at $747 million down $32 million, the entirety of that is the government contracts that Mark referenced and we had referenced earlier in our year end call, but it's up from December which is a trend we expect to continue as the year goes on. We continue to see backlog growth in our mechanical services business in building services. In fact the backlog there is in an all-time high and again that leading us to believe is it non-res will have growth this year and this contribution in the first quarter, when they had backlog growth start to see velocity building in that business. And again it's mainly commercial work, the drop again in building services from the two government JV's. Our backlog is well balanced and we continue to see solid bidding opportunities in front of us. The target remain disciplined like we always are. We are confident in our ability to execute as a non-residential market slowly improves. Now I'll be on Page 12 and 13. And it's really what everybody is been waiting for in this whole call, what do we think about the rest of the year. Now we're going to leave guidance unchanged. Revenues of $6.6 billion and with the range of diluted EPS from continuing operations of $2.65 to $2.95. Here's what we expect as the year progresses, we expect revenue growth and that is afforded by our strong book-to-bill and backlog growth. The stronger the revenue growth, the higher we're likely to get into our guidance range. We expect revenue momentum to build in our construction business coincident with our backlog growth and we expect margins improved in our construction business overall and especially in our long time and well performing electrical business. We expect margins to improve throughout the year and SG&A we expect to moderate and Mark and I both went through the reasons why. We don't have a fix cost issue here. You think about it, our headcount is up other than what we had in the industrial spike less than 2% and our increases in salary and everything less than 2%. Partly the image of spendthrifts [ph] in our business. We do not know, how much of the deferred turnaround work will happen in 2015 or how much it will be delayed in to 2016 at this point. Now some of this facilities are still on strike and not settled. We expect to have some unsold opportunities present themselves to us as the refineries are running at near record levels of utilization and that drives demand for our services in not only industrial services broadly, but also our shop services, not only field but also shop. We are in a very fluid situation with our customers in refinery and petrochemical space right now. We are working with our strike customers especially on a daily basis to understand how that work will be scheduled on a go forward basis. We do expect a strong fall turnaround at the season at this point. We expect building services performance to continue to improve through year end. Mechanical services performing well and we expect that to continue. Site-based services had a better quarter absent to snow in the first quarter and then executed terrific on the snow that we did have. We remain optimistic in our opportunities as we performed okay in Q1, despite significant external headwinds. And now we reiterate for the third time on this call. Without these headwinds, we would have a record or near record Q1. With respect to capital deployment, we look to fund organic growth, have seen a little better acquisition environment for negotiated transaction versus prior year and will continue return cash to shareholders through dividend and buybacks. With that, we'd love to take your questions and I'll turn the call back over to Genisha [ph]. Genisha?
