Thank you, Brian and good morning, everyone. As Brian mentioned, Owens Corning delivered record revenue of $7.2 billion and adjusted EBIT of $828 million in 2019. Through focused working capital management and discipline capital spending, we produce record operating cash flow and almost $600 million of free cash flow for the year. Please turn to Slide 5 which summarizes key financial data for the fourth quarter and fiscal year 2019. The tables in today's news release and the Form 10-K include more detailed financial information. For the fourth quarter, we reported consolidated net sales of $1.7 billion, down about 2% versus 2018. Each of our businesses faced into some pricing headwinds and we face modest market declines in technical insulation in Europe and in the U.S. shingle market. Adjusted EBIT for the fourth quarter of 2019 was $204 million, down $24 million compared to Q4, 2018. The lower EBIT performance in the quarter was driven by insulation which was down $26 million. Net earnings attributable to Owens Corning for the fourth quarter was $73 million compared to $171 million in Q4, 2018. Adjusted earnings for the fourth quarter of 2019 were $125 million or $1.13 per diluted share, compared to $152 million, or $1.38 per diluted share in Q4, 2018. For 2019, net earnings were $405 million compared to $545 million in 2018. Adjusted earnings for 2019 were $500 million or $4.54 per diluted share compared to $550 million, or $4.94 per diluted share in 2018. The full year EPS comparison was affected by two below the line adjusting items in 2019. First, in Q1, we adjusted out of $12 million non-cash income tax charge related to 2017 US corporate tax reform, compared to a $23 million non-cash income tax benefit that was recognized in 2018. Second, in Q3, we issued a green bond and tendered portions of our 2022 and 2036 bonds. We incurred a $32 million loss on extinguishment of debt that was adjusted out. Moving on depreciation and amortization expense for the quarter was $120 million, up $10 million as compared to Q4, 2018. The growth in the fourth quarter of 2019 was due to accelerated depreciation from the insulation restructuring actions announced in October. For 2019, depreciation and amortization expense was $457 million. Our capital additions for the year were $451 million, down about $90 million versus 2018. During 2019, we focused capital spending on investments that will improve throughput, drive cost reductions and support organic growth. On Slide 6, you will see our adjusting items. Reconciling full year 2019 reported EBIT of $753 million to adjusted EBIT of $828 million. For the year, adjusting items to EBIT totaled $75 million. As discussed in October, we took actions to reduce future pension obligations by transferring about $90 million of pension obligations through the purchase of an annuity contract with plan assets. In the fourth quarter, we recorded a $43 million non cash settlement charge. We also recorded $28 million of restructuring costs, primarily associated with insulation network optimization actions announced in October. Please turn to Slide 7 which provides a high-level review of full year adjusted EBIT comparing 2019 to 2018. Adjusted EBIT decreased $33 million; roofing EBIT increased by $21 million as compared to the prior year. Composite EBIT decreased by $4 million and insulation EBIT decreased by $60 million. General corporate expenses were $104 million, down $10 million from 2018. Now please turn to Slide 8 which provides a more detailed review of business results beginning with insulation. Sales for the fourth quarter were $723 million, down 1% from Q4, 2018. The decrease was driven by lower sales volumes in the technical and other building insulation business in Europe and the negative impact of foreign currency. EBIT for the fourth quarter was $89 million, down $26 million compared to 2018. The EBIT results were largely consistent with the expectations we shared in October. The year-over-year decline was largely driven by continued curtailment costs and lower volumes. For the full year, sales were $2.7 billion, down 2% versus 2018 with growth in technical and other building insulation more than offset by lower volumes in the North American residential fiberglass insulation business. Higher selling prices were partially offset by negative foreign currency translation. In 2019, insulation EBIT declined by $60 million to $230 million as progress in technical and other building insulation was more than offset by lower volumes and curtailment costs in North American residential fiberglass insulation. For the year, improved performance in technical and other insulation was driven by volume growth, improved pricing and strong commercial and operational execution. Now please turn to Slide 9 for a review of our composites business. Sales in composites for the fourth quarter were $480 million, flat to the same period in 2018 and up 1% on a constant currency basis. Despite slower global growth, composites volumes continue to moderately outpaced the broader market. EBIT for the quarter was $56 million flat to Q4, 2019; continued strong commercial and operational performance offset input cost inflation, unfavorable currency and a competitive price environment. For the quarter, composites delivered 12% EBIT margins. Full year sales were $2.1 billion, up 1% as compared to 2018. Revenue grew 3% on a constant currency basis driven by 4% volume growth. Our volumes outpaced the broader market on strength and wind and gloss nonwovens. In 2019, EBIT declined by $4 million to $247 million. The benefit of favorable manufacturing performance and volume growth were more than offset by higher input cost inflation, lower selling prices and negative foreign currency. Slide 10 provides an overview of our roofing business. Roofing sales for the quarter were $529 million, down 3% compared with Q4, 2018 on slightly lower shingle volumes and moderately low selling prices. In the fourth quarter, US asphalt shingle industry shipments were down 5% versus Q4, 2018. As expected, our shingle volumes outperform the market in the fourth quarter. EBIT for the quarter was $87 million, a $4 million increase from the prior year as a seasonal decline in asphalt costs and lower transportation costs offset moderately lower prices. Roofing sales for 2019 were $2.6 billion, up 6% versus 2018. U.S. asphalt shingle industry shipments grew 2% over 2018. OC's volumes outpaced the market through solid commercial execution. In 2019, Roofing EBIT improved by $21 million to $455 million on above market volume growth. Our full year price improvement and tailwind from transportation costs more than offset the impact of asphalt inflation. Our cash contribution margins continue to be healthy and the business is well positioned for a strong 2020. Please turn to Slide 11 where I will discuss significant financial highlights for 2019. As Brian mentioned, free cash flow improved by $324 million from 2018 and we delivered strong free cash flow conversion of 118%. Over the last five years, we have delivered free cash flow conversion in excess of 100% on strong earnings, good working capital performance and our advantage tax position. During 2019, we return $95 million to shareholders in dividends and $48 million in share repurchases. At the end of 2019, 3.6 million shares were available for repurchase. Also in 2019, Owens Corning became the first US industrial company to issue a green bond extending our weighted average bond maturity by 1 year to 16 years. We continue to maintain an investment grade balance sheet and in December, we received an upgrade from Moody's. Owens Corning is now rated investment grade by all three major rating agencies. Please turn to Slide 12 for a discussion of select financial guidance for the year. In February, the company's Board of Directors declared a quarterly cash dividend of $0.24 per share payable on April 3rd to shareholders of record as of March 6. Since inception in 2014, the dividend has grown an average of 7% per year. In 2020, we expect the combination of higher earnings, working capital improvement and focused capital spending to drive another year of strong free cash flow conversion. The company plans to prioritize free cash flow in 2020 to ongoing dividends and to pay off the term loan associated with proc. Additionally, free cash flow could be available for share repurchases. As we look forward, we are targeting overtime to return at least 50% of free cash flow to investors through dividends and share repurchases. Moving on we expect corporate expenses between $125 million and $135 million. The expected year-over-year growth is primarily due to the reset of performance-based compensation to more normalized levels. We anticipate first quarter total corporate expenses to be up modestly versus Q1, 2019. We expect capital additions to be in line with expected depreciation and amortization expense of approximately $460 million. Interest expense is expected to be about $115 million, down from $131 million in 2019 on reduced total debt and lower interest rates. Our 2020 effective tax rate is expected to be 26% to 28% of adjusted pre-tax earnings. As a result of our foreign tax credits and other planning, we expect our 2020 cash tax rate to be 10% to 12% of adjusted pre-tax earnings. Now please turn to Slide 13 as I return the call over to Brian to discuss the outlook for our company. Brian?
