Thanks Mike. Let's start on slide five, where we detail key financial figures for the third quarter of 2009. You'll find more detailed financial information in the tables of today's news release and the form 10-Q that was filed earlier. Today, we reported first quarter 2009 consolidated net sales of $1.1 billion, a 21% decrease compared to 2008. The quarter was highlighted by strong Roofing sales that were up 49% compared with the first quarter 2008, continuing momentum began in the second quarter of last year. Sales of insulation were lower because of the continued weakness in the U.S housing market. Composites sales declined primarily as a result of the global economic slowdown. As a reminder, when we look at our period of appeared comparability, our primary measure is adjusted earnings before interest and tax. Adjusted EBIT. In a moment, I will review our reconciliation of items to get to adjusted EBIT. These items totaled $50 million in first quarter 2009 compared to $35 million during the same period in 2008. Our adjusted EBIT for the first quarter 2009 was $32 million compared with $56 million in the first quarter 2008. We were very pleased with these results; particularly given the weaker year-over-year global economic environment and the continued decline in the U.S. housing market. Adjusted earnings for the first quarter 2009 were $5 million or $0.04 per diluted share as compared to first quarter 2008 adjusted earnings at $15 million or $0.11 per diluted share. In the first quarter, marketing and administrative expenses decreased by $18 million. This reduction was due to savings from various cost reduction actions taken during 2008 and 2009 as well as reduced performance based compensation expense and reduced acquisition, integration and transaction costs. Depreciation and amortization total $84 million for the first quarter. We currently estimate our depreciation and amortization will total approximately $340 million in 2009. This is a little lower than our prior guidance in range of $350 million primarily due to reduced capital expenditures throughout 2009. Our capital expenditures totaled $40 million in the first quarter. As Mike said, we expect that they will be about $225 million for the full year 2009, excluding purchases of precious metal. Net debt was $2.3 billion at the end of the quarter. We expect to reduce net debt to approximately $1.8 billion by the end of 2009. Moving to slide six, you can see the detail associated with the reconciliation of our first quarter adjusted EBIT of $32 million to reported EBIT of negative $18 million. We provide this analysis as a major of our current operating results. We are responding to the current environment to reassess our cost structure across the company. In the second half of 2008, and through the first quarter of 2009 we have taken various cost reduction actions including significant capacity curtailments, extending plants downtimes, reducing head count, underlying projects. These actions will contribute to cost reductions of about $160 million in 2009 of which we expect at least half will be permanent reductions where the cost will not return when we restart ideal production capacity. We expect that $46 million of charges in 2009 relates to achieving these savings of which we incurred $30 million in the first quarter. The integration of the Composites acquisition continues to deliver synergies well ahead of our original plans. In 2009 we expect to deliver a total of $75 million in synergies, up from the $50 million we realized in 2008. We incurred $6 million of integration costs in the first quarter associated with achieving these ongoing savings. Next, as you have seen in prior quarters we adjusted for the non-cash amortization of costs associated with the Employee emergence equity program, a total of $6 million. These shares which have a three year wasting schedule and will be amortized in the P&L until October 2009 were awarded to employees at the time of our -- from chapter 11 in 2006. Now, if you move to slide seven, you will see an illustration of adjusted EBIT performance, comparing first quarter 2009 with the same quarter in 2008 based on business contribution. We illustrate this to show how our businesses have evolved year-over-year. Adjusted EBIT declined $24 million from the first quarter 2008 to first quarter 2009. Our Roofing business continued to deliver outstanding results in the quarter and maintain the significant momentum that began in 2008. This improvement was offset by both insulation and Composite businesses, which faced weaker demand in their respective markets. With that as background, turn to slide eight and we will begin a more detailed review of our shipments segments starting with Building Materials. In the first quarter, Building Materials had net sales of $766 million, a 5% increase over the first quarter 2008. Building Materials delivered a significant turnaround in EBIT of $53 million compared to a negative EBIT of $4 million in 2008. The following two slides discuss these results in more detail by highlighting the key businesses within the Building Material segment, the Roofing business and the insulation business. First, slide nine provides an overview of our Roofing business, in the first quarter this business continued it's outstanding performance. Roofing net sales for the quarter improved nearly 50% from the first quarter 2008 as higher selling prices recovered prior increases in raw material costs, particularly asphalt. The business delivered $99 million of EBIT in the third quarter 2009, a record quarter for this business. This milestone also represents a tremendous turnaround from last years negative EBIT of $17 million. As Mike outlined in his earlier remarks, we have taken significant actions since 2007 to improve profitability of our business. We have achieved improvements in our production processes, including energy efficiencies and reduction in the raw material cost of our shingle design. We have also reduced overall manufacturing fixed costs. In addition, we have launched new product lines, improved our mix and grown our accessories business. These programs had a significant impact on 2008, by the end of 2009 these programs are expected to have delivered $100 million of improvement compared to 2007. In addition, the Roofing industry is attractive and we have demonstrated that our business can deliver operating margins well above 10%. We believe that this business will continue to see strong operating margins for the rest of 2009 and beyond. With this level of performance, Roofing has established itself as a strong business within our portfolio with enduring value. Next on to slide 10, our insulation business. Our insulation business continues to feel the impact of the 11 consecutive quarters of progressively declining US housing starts. First quarter net sales in this business were down 24% compared with the first quarter of 2008. This decline was primarily due to a reduction in volumes as prices have remained stable, since the second half of 2008. The decline in insulation net sales was less severe than the decline in US housing stocks due to our diversified portfolio of markets and geographies. The Insulation business lost money in the first quarter, the first quarter is seasonally weak our demand is driven by actual fourth quarter housing starts which are lower than the seasonally adjusted number. EBIT was a loss of $39 million due to the impact of lower demand on our sales and under utilization of our production capacity. In response to the prolonged weakness in demand we continue to take actions to reduce active production capacity and to align our cost structure with market demand. As a result of these actions about 50% of our fiberglass insulation capacity is now curtailed. Despite these actions this business will struggle to achieve profitability until demand improves. This is a great business in a well structured industry. Owens Corning Pink fiberglass insulation is a powerful and enduring brand. We are the clear market leader, well positioned to return to historical levels of performance when demand improves as we know it will. Next slide 11, provides an overview of our Composite segment. Composites net sales decreased 48% in the first quarter 2009 as compared to the same period in 2008. Approximately two third of this decrease was the result of a lower sales volumes quote by the global economic slowdown that began in the fourth quarter of 2008. The remainder of the decrease was due to the May 2008 divestiture of two firms in Europe and an unfavorable currency variance of $41 million from translating sales denominated in foreign currencies into U.S. dollars. First quarter EBIT for the business was negative $18 million compared to a positive $64 million for the same period in 2008. Substantially all of this decrease was a result of lower sales volumes including the impact of underutilization of our production capacity. In our fourth quarter call, we indicated that December reinforcement volumes were down by as much as 45% compared to the trend established in the first three quarters of 2008. We have seen demand increase every month in the first quarter. However, we are currently experiencing sales volumes down by about 35%. These trends were broadly consistent across our different products and geographic regions. We expect that industry demand could be down as much as 20% in 2009 compared to 2008. As Mike mentioned, we have curtailed more than 40% of our global reinforcement's production capacity. And as a result, we're now producing less than we sell each month. We expect the gradual increase in demand to persist throughout 2009. We will continue to produce at a lower level to return our business to cash generation in the second quarter. Then we expect our business will return to profitability in the third quarter. Next, we have a few additional items to cover before turning to our Q&A. On slide 12, in the first quarter 2009 the company changed its method of accounting for inventories held by our US companies from the LIFO method to the FIFO method. In addition to confirming the company's worldwide inventories to a consistent costing method, we believe that it will provide better matching of the company's expenses with its revenues. This change in accounting principle has been applied retrospectively to all prior periods we present, which in the first quarter of 2008 resulted in an EBIT increase of $2 million incorporate. Our reported business results have historically being based on the FIFO inventory costing method and so there is no change to prior periods for these. Next, you will see a description of both our cash tax position as well as reported tax expense. We expect the cash tax in 2009, will be less than 2008, but overall cash taxes paid were $33 million. In addition, we estimate that our long term effective tax rate will be 25% based on a blend of our U.S. and non-U.S. operations. Therefore, to improve comparability of our adjusted results we applied just 25% tax rates to pretax earnings to arrive at adjusted earnings. Now, slide 13, we have a resilient balance sheet. We have no material debt maturities coming due until the fourth quarter of 2011, and we have $428 million available in our revolving credit facility as of the end of the quarter. In addition, we have $90 million of cash on hand. We expect that the cash we have on hand coupled with future cash flows from operations and other available sources of funds will provide ample liquidity to allow us to meet our cash requirements, capital investment plans, and to endure significant additional market volatility. In addition this month Standard and Poor's rating services published an updated credit profile on the company affirming our investment grade corporate credit rating. We have taken significant actions to maximize our cash flow in 2009. We are driving $160 million of cost out of the business during the year and we're reducing capital expenditures by $140 million from 2008 levels. These measures, along with a strong performance of our Roofing business had improved our confidence and the outlook for free cash flow. We believe that free cash flow of $150 million is achievable in 2009. With that, Scott, back to you for Q&A.
