ITEM 1.

BUSINESS

OVERVIEW

Owens Corning was founded in 1938. Since then the Company has continued to grow as a market-leading innovator of glass fiber technology. Owens Corning is a world leader in composite and building materials systems, delivering a broad range of high-quality products and services. Our products range from glass fiber used to reinforce composite materials for transportation, electronics, marine, infrastructure, wind-energy and other high-performance markets to insulation and roofing for residential, commercial and industrial applications. As a sustainability-focused company, Owens Corning creates value for our customers and stockholders, positively impacts the environment and enhances the lives of those with whom we interact.

Unless the context indicates otherwise, the terms “Owens Corning,” “Company,” “we” and “our” in this report refer to Owens Corning and its subsidiaries. References to a particular year mean the Company’s year commencing on January 1 and ending on December 31 of that year. The term “Predecessor” in this report refers to Owens Corning’s predecessor company, Owens Corning Sales, LLC and its subsidiaries.

SEGMENT OVERVIEW

We operate within two segments: Composites, which includes our Reinforcements and Downstream businesses; and Building Materials, which includes our Insulation, Roofing, and Other businesses. Our Composites and Building Materials reportable segments accounted for approximately 37% and 63% of our total reportable segment net sales, respectively, in 2010.

Note 2 to the Consolidated Financial Statements contains information regarding net sales to external customers and total assets attributable to each of Owens Corning’s reportable segments and geographic regions, earnings before interest and taxes for each of Owens Corning’s reportable segments, and information concerning the dependence of our reportable segments on foreign operations, for each of the years 2010, 2009 and 2008.

Composites

Owens Corning glass fiber materials can be found in over 40,000 end-use applications within seven primary markets: power and energy, housing, water distribution, industrial, transportation, consumer and aerospace/military. Such end-use applications include pipe, roofing shingles, sporting goods, computers, telecommunications cables, boats, aircraft, defense, automotive, industrial containers and wind-energy. Our products are manufactured and sold worldwide. We primarily sell our products directly to parts molders and fabricators. Within the building and construction market, our Composites segment sells glass fiber and/or glass mat directly to a small number of major shingle manufacturers, including our own Roofing business.

Our Composites segment is comprised of our Reinforcements and Downstream businesses. Within the Reinforcements business, the Company manufactures, fabricates and sells glass reinforcements in the form of fiber. Within the Downstream business, the Company manufactures and sells glass fiber products in the form of fabrics, mat, veil and other specialized products.

Demand for composites is driven by general global economic activity and, more specifically, by the increasing replacement of traditional materials such as aluminum, wood and steel with composites that offer lighter weight, improved strength, lack of conductivity and corrosion resistance. We estimate that over the last 15 years, on average, annual global demand for composite materials grew at about 1.5 times to 2 times global GDP.

-2-

ITEM 1.

BUSINESS (continued)

We compete with composite manufacturers worldwide. According to various industry reports and Company estimates, our Composites segment is a world leader in the production of glass fiber reinforcement materials. Primary methods of competition include innovation, quality, customer service and global geographic reach. For our commodity products, price is also a method of competition. Significant competitors to the Composites segment include China Fiberglass Co., Ltd., PPG Industries, Taishan Glass Fiber Co., Ltd, and Johns Manville.

Our manufacturing operations in this segment are generally continuous in nature, and we warehouse much of our production prior to sale since we operate primarily with short delivery cycles.

Building Materials

Our Building Materials reportable segment is comprised of the following businesses:

Insulation

Insulation includes insulating products, Building Materials Europe and Construction Services.

Our insulating products help customers conserve energy, provide improved acoustical performance and offer convenience of installation and use, making them a preferred insulating product for new home construction and remodeling. These products include thermal and acoustical batts, loose fill insulation, foam sheathing and accessories, and are sold under well-recognized brand names and trademarks such as Owens Corning PINK FIBERGLAS^® Insulation. We sell our insulation products primarily to insulation installers, home centers, lumberyards, retailers and distributors in the United States and Canada.

Demand for Owens Corning’s insulating products is driven by new residential construction, remodeling and repair activity, commercial and industrial construction activity, increasingly stringent building codes and the growing need for energy efficiency. Sales in this business typically follow seasonal home improvement, remodeling and renovation and new construction industry patterns. Demand for new residential construction follows on a three-month lagged basis. The peak season for home construction and remodeling in our geographic markets generally corresponds with the second and third calendar quarters, and therefore, our sales levels are typically higher during the second half of the year.

Our Insulation business competes primarily with manufacturers in the United States. According to various industry reports and Company estimates, Owens Corning is North America’s largest producer of residential, commercial and industrial insulation, and the second-largest producer of extruded polystyrene foam insulation. Principal methods of competition include innovation and product design, service, location, quality, price and compatibility of systems solutions. Significant competitors in this business include CertainTeed Corporation, Johns Manville, Dow Chemical and Knauf Insulation.

Working capital practices for this business historically has followed a seasonal cycle. Typically, our insulation plants run continuously throughout the year. This production plan, along with the seasonal nature of the business, generally results in higher finished goods inventory balances in the first half of the year. Since sales increase during the second half of the year, our accounts receivable balances are typically higher during this period.

Roofing

Our primary products in the Roofing business are laminate and strip asphalt roofing shingles. Other products include oxidized asphalt and roofing accessories. We have been able to meet the growing demand for longer lasting, aesthetically attractive laminate products with modest capital investment.

-3-

ITEM 1.

BUSINESS (continued)

We sell shingles and roofing accessories primarily through home centers, lumberyards, retailers, distributors and contractors in the United States and sell other asphalt products internally to manufacture residential roofing products and externally to other roofing manufacturers. We also sell asphalt to roofing contractors and distributors for built-up roofing asphalt systems and to manufacturers in a variety of other industries, including automotive, chemical, rubber and construction.

Demand for products in our Roofing business is generally driven by both residential repair and remodeling activity and by new residential construction. Roofing damage from strong storms can significantly increase demand in this business. As a result, sales in this segment do not always follow seasonal home improvement, remodeling and new construction industry patterns as closely as our Insulation business.

Our Roofing business competes primarily with manufacturers in the United States. According to various industry reports and Company estimates, Owens Corning’s Roofing business is the second largest producer of asphalt roofing shingles in the United States. Principal methods of competition include innovation and product design, proximity to customers and quality. Significant competitors in the Roofing business include GAF-ELK, CertainTeed Corporation and TAMKO.

Our manufacturing operations are generally continuous in nature, and we warehouse much of our production prior to sale since we operate with relatively short delivery cycles. One of the raw materials important to this business is sourced from a sole supplier. We have a long-term supply contract for this material, and have no reason to believe that any availability issues will exist. If this supply was to become unavailable, our production could be interrupted until such time as the supplies again became available or the Company reformulated its products. Additionally, the supply of asphalt, another significant raw material in this segment, has been constricted at times. Although this has not caused an interruption of our production in the past, prolonged asphalt shortages would restrict our ability to produce products in this business.

Other

Other includes our North America Masonry Products business (“Masonry Products”). On December 31, 2010, the Company sold Masonry Products to Boral Industries Ltd. (“Boral”). Through Masonry Products, Owens Corning manufactured and sold manufactured stone and brick veneers used in residential and commercial new construction and remodeling under a number of brand names including Cultured Stone^® and ProStone^TM. Manufactured stone veneer replicates the texture and colors of natural stone while offering improved features such as reduced weight, ease of installation and cost efficiency. See Note 9 to the Consolidated Financial Statements for information regarding the sale of Masonry Products to Boral.

GENERAL

Major Customers

No one customer accounted for more than 10% of our consolidated net sales for 2010. A significant portion of the net sales in our Building Materials segment is generated from large United States home improvement retailers.

Patents and Trademarks

Owens Corning continuously works toward improving products and processes. Because of this continuous innovation process, patents and trademarks play a key role in each of our businesses. Owens Corning has numerous United States and foreign patents and trademarks issued and applied for relating to products and processes in each business, resulting from research and development efforts. Owens Corning does not expect the expiration of existing patents and trademarks to have a material adverse affect on the business as a whole.

-4-

ITEM 1.

BUSINESS (continued)

Through continuous and extensive use of the color PINK since 1956, Owens Corning became the first owner of a single color trademark registration in the United States. For over 25 years, Owens Corning has licensed from Metro-Goldwyn-Mayer Studios Inc. (the owner of the Pink Panther character) the exclusive right to use the Pink Panther in all of our major market segments and we make extensive use of the Pink Panther character in the marketing of our products. We believe our PINK trademark and the Pink Panther character are some of the most widely recognized marks in the building products industry.

We have issued royalty-bearing patent licenses to companies in several foreign countries.

Including registered trademarks for the Owens Corning logo and the color PINK, Owens Corning has approximately 250 trademarks registered in the United States and approximately 1,500 trademarks registered in other countries. Owens Corning has approximately 400 patents in the United States and approximately 1,300 patents issued in other countries.

Backlog

Our customer volume commitments are generally short-term, and we do not have a significant backlog of orders.

Research and Development

The Company’s research and development expense during each of the last three years is presented in the table below (in millions):


Period	Research and Development Expense
Twelve Months Ended December 31, 2010	$	76
Twelve Months Ended December 31, 2009	$	61
Twelve Months Ended December 31, 2008	$	69

Environmental Control

Owens Corning is committed to complying with all environmental laws and regulations that are applicable to our operations. We are dedicated to continuous improvement in our environmental, health and safety performance.

We have not experienced a material adverse effect upon our capital expenditures or competitive position as a result of environmental control legislation and regulations. Operating costs associated with environmental compliance were approximately $34 million in 2010. We continue to invest in equipment and process modifications to remain in compliance with applicable environmental laws and regulations worldwide.

Our manufacturing facilities are subject to numerous national, state and local environmental protection laws and regulations. Regulatory activities of particular importance to our operations include those addressing air pollution, water pollution, waste disposal and chemical control. The most significant current regulatory activity is the United States Environmental Protection Agency’s ongoing evaluation of the past air emission and air permitting activities of the glass industry, including fiberglass insulation. We expect passage and implementation of new laws and regulations specifically addressing climate change, toxic air emissions, ozone forming emissions and fine particulate during the next two to five years. However, based on information known to the Company, including the nature of our manufacturing operations and associated air emissions, at this time we do not expect any of these new laws, regulations or activities to have a material adverse effect on our results of operations, financial condition or long-term liquidity.

-5-

ITEM 1.

BUSINESS (continued)

We have been deemed by the United States Environmental Protection Agency to be a Potentially Responsible Party (“PRP”) with respect to certain sites under the Comprehensive Environmental Response Compensation and Liability Act. We have also been deemed a PRP under similar state or local laws and in other instances other PRPs have brought suits against us as a PRP for contribution under such federal, state, or local laws. At December 31, 2010, we had environmental remediation liabilities as a PRP at 19 sites where we have a continuing legal obligation to either complete remedial actions or contribute to the completion of remedial actions as part of a group of PRPs. For these sites we estimate a reserve to reflect environmental liabilities that have been asserted or are probable of assertion, in which liabilities are probable and reasonably estimable. At December 31, 2010, our reserve for such liabilities was $9 million.

Number of Employees

As of December 31, 2010 Owens Corning had approximately 15,000 employees. Approximately 7,600 of such employees are subject to collective bargaining agreements. We believe that our relations with employees are good.

AVAILABILITY OF INFORMATION

Owens Corning makes available, free of charge, through its website the Company’s Annual Report on Form 10-K, Quarterly Reports on Form 10-Q, Current Reports on Form 8-K and all amendments to those reports as soon as reasonably practicable after such material is electronically filed with or furnished to the Securities and Exchange Commission. These documents are available through the Investor Relations page of the Company’s website at www.owenscorning.com.

ITEM 1A.

RISK FACTORS

RISKS RELATED TO OUR BUSINESS AND OUR INDUSTRY

Low levels of residential or commercial construction activity can have a material adverse impact on our business and results of operations.

A portion of our products are used in the markets for residential and commercial construction, repair and improvement, and demand for certain of our products is affected in part by the level of new residential construction, although typically a number of months after the change in the level of construction. Historically, construction activity has been cyclical and is influenced by prevailing economic conditions, including the level of interest rates and availability of financing and other factors outside our control.

Worldwide economic conditions and credit tightening could have a material adverse impact on the Company.

The Company’s business may be adversely impacted by changes in United States or global economic conditions, including inflation, deflation, interest rates, availability of capital, consumer spending rates, energy availability and costs, and the effects of governmental initiatives to manage economic conditions. Volatility in financial markets and the deterioration of national and global economic conditions could materially adversely impact the Company’s operations, financial results and/or liquidity including as follows:

•

the financial stability of our customers or suppliers may be compromised, which could result in additional bad debts for the Company or non-performance by suppliers;

•

one or more of the financial institutions syndicated under the Credit Agreement applicable to our committed senior revolving credit facility may cease to be able to fulfill their funding obligations, which could adversely impact our liquidity;

•

it may become more costly or difficult to obtain financing or refinance the Company’s debt in the future;

•

the value of the Company’s assets held in pension plans may decline; and/or

•

the Company’s assets may be impaired or subject to write down or write off.

Uncertainty about global economic conditions may cause consumers of our products to postpone spending in response to tighter credit, negative financial news and/or declines in income or asset values. This could have a material adverse impact on the demand for our products and on our financial condition and operating results. A deterioration of economic conditions would likely exacerbate these adverse effects and could result in a wide-ranging and prolonged impact on general business conditions, thereby negatively impacting our operations, financial results and/or liquidity.

We face significant competition in the markets we serve and we may not be able to compete successfully.

All of the markets we serve are highly competitive. We compete with manufacturers and distributors, both within and outside the United States, in the sale of insulating products and composite products. We also compete with other manufacturers and distributors in the sale of roofing materials, industrial asphalts, and other products. In some cases, we face competition from manufacturers in countries able to produce similar products at lower costs. We also face competition from the introduction by competitors of new products or technologies that may address our customers’ needs in a better manner, whether based on considerations of cost, usability, effectiveness, sustainability or other features or benefits. If we are not able to successfully commercialize our innovation

-7-

ITEM 1A.

RISK FACTORS (continued)

efforts, we may lose market share. Price competition or overcapacity may limit our ability to raise prices for our products when necessary, may force us to reduce prices and may also result in reduced levels of demand for our products and cause us to lose market share. Our inability to compete and the loss of customers and pricing pressures caused by such competition, overcapacity or other reasons could reduce the sales of our products, thereby adversely impacting our business, financial condition and results of operations.

Our sales may fall rapidly in response to declines in demand because we do not operate under long-term volume agreements to supply our customers and because of customer concentration in certain segments.

Many of our customer volume commitments are short-term; therefore, we do not have a significant manufacturing backlog. As a result, we do not have the hedge provided by long-term volume contracts against downturns in customer demand and sales. Further, our costs are not susceptible to immediate adjustment in response to changes in sales. In addition, although no single customer represents more than 10% of our annual sales, sales of some of the products in our building materials product category are dependent on a limited number of customers, who account for a significant portion of such sales. The loss of key customers for these products, or a significant reduction in sales to those customers, could significantly reduce our revenues in these products. If key customers experience financial pressure, they could attempt to demand more favorable contractual terms, which would place additional pressure on our margins and cash flows. Lower demand for our products could adversely impact our business, financial condition and results of operations.

Adverse weather conditions and the level of severe storms could have a material adverse impact on our results of operations.

Weather conditions and the level of severe storms can have a significant impact on the markets for residential and commercial construction, repair and improvement.

•

Generally, any weather conditions that slow or limit residential or commercial construction activity can adversely impact demand for our products.

•

A portion of our annual product demand is attributable to the repair of damage caused by severe storms. In periods with below average levels of severe storms, demand for such products could be reduced.

Lower demand for our products could adversely impact our business, financial condition and results of operations.

Our level of indebtedness could adversely impact our ability to refinance such indebtedness when desired or to raise additional capital to fund our operations and limit our ability to react to changes in the economy or our industry.

Our debt level and degree of leverage could have important consequences, including the following:

•

they may limit our ability to obtain additional debt or equity financing for working capital, capital expenditures, debt service requirements, acquisitions and general corporate or other purposes;

•

a substantial portion of our cash flows from operations could be required for the payment of principal and interest on our indebtedness and may not be available for other business purposes;

•

certain of our borrowings, are at variable rates of interest, exposing us to the risk of increased interest rates;

-8-

ITEM 1A.

RISK FACTORS (continued)

•

if due to liquidity needs we must replace any borrowings upon maturity, we would be exposed to the risk that we will be unable to do so as the result of market, operational or other factors;

•

they may limit our ability to adjust to changing market conditions and place us at a competitive disadvantage compared to our competitors that have less debt; and

•

we may be vulnerable in a downturn in general economic conditions or in our business, or we may be unable to carry out important capital spending.

In addition, the credit agreement governing our senior credit facility and the indentures governing our senior notes contain various covenants that impose operating and financial restrictions on us and/or our subsidiaries.

Our ongoing efforts to increase productivity and reduce costs may not result in anticipated savings in operating costs.

Our cost reduction and productivity efforts, including those related to our existing operations, production capacity expansions and new manufacturing platforms, may not produce anticipated results. Our ability to achieve cost savings and other benefits within expected time frames is subject to many estimates and assumptions. These estimates and assumptions are subject to significant economic, competitive and other uncertainties, some of which are beyond our control. If these estimates and assumptions are incorrect, if we experience delays, or if other unforeseen events occur, our business, financial condition and results of operations could be adversely impacted.

We may be exposed to increases in costs of energy, materials and transportation or reductions in availability of materials and transportation, which could reduce our margins and harm our results of operations.

Our business relies heavily on certain commodities and raw materials used in our manufacturing processes. Additionally, we spend a significant amount on inputs and services that are influenced by energy prices, such as natural gas, asphalt, a large number of chemicals and resins and transportation costs. Price increases for these inputs could raise costs and reduce our margins if we are not able to offset them by increasing the prices of our products, improving productivity or hedging where appropriate. Availability of certain of the raw materials we use has, from time to time, been limited, and our sourcing of some of these raw materials from a limited number of suppliers, and in some cases a sole supplier, increases the risk of unavailability. Despite our contractual supply agreements with many of our suppliers, it is possible that we could experience a lack of certain raw materials which could limit our ability to produce our products, thereby adversely impacting our business, financial condition and results of operations.

Our hedging activities to address energy price fluctuations may not be successful in offsetting increases in those costs or may reduce or eliminate the benefits of any decreases in those costs.

In order to mitigate short-term variation in our operating results due to commodity price fluctuations, we hedge a portion of our near-term exposure to the cost of energy, primarily natural gas. The results of our hedging practices could be positive, neutral or negative in any period depending on price changes of the hedged exposures.

Our hedging activities are not designed to mitigate long-term commodity price fluctuations and, therefore, will not protect us from long-term commodity price increases. In addition, in the future our hedging positions may not correlate to our actual energy costs, which would cause acceleration in the recognition of unrealized gains and losses on our hedging positions in our operating results.

-9-

ITEM 1A.

RISK FACTORS (continued)

The Company’s income tax net operating loss carryforwards may be limited and our results of operations may be adversely impacted.

The Company has substantial deferred tax assets related to net operating losses (NOLs) for United States federal and state income tax purposes, which are available to offset future taxable income. However, the Company’s ability to utilize the NOLs may be limited as a result of certain events, such as insufficient future taxable income prior to expiration of the NOLs or annual limits imposed under Section 382 of the Internal Revenue Code, or by state law, as a result of a change in control. A change in control is generally defined as a cumulative change of 50% or more in the ownership positions of certain stockholders during a rolling three year period. Changes in the ownership positions of certain stockholders could occur as the result of stock transactions by such stockholders and/or by the issuance of stock by the Company. Such limitations may cause the Company to pay income taxes earlier and in greater amounts than would be the case if the NOLs were not subject to such limitations.

Should the Company determine that it is likely that its recorded NOL benefits are not realizable, the Company would be required to reduce the NOL tax benefits reflected on its financial statements to the net realizable amount by establishing a valuation reserve and recording a corresponding charge to current earnings. If the Company is required to establish a valuation reserve, recording the corresponding charge to current earnings would have an adverse effect on the Company’s financial condition and results of operations in the period in which it is recorded. Conversely, if the Company is required to reverse any portion of the accounting valuation against its deferred tax assets related to its NOLs, such reversal could have a positive effect on the Company’s financial condition and results of operations in the period in which it is recorded.

Our operations require substantial capital, leading to high levels of fixed costs that will be incurred regardless of our level of business activity.

Our businesses are capital intensive, and regularly require capital expenditures to expand operations, maintain equipment, increase operating efficiency and comply with environmental laws, leading to high fixed costs, including depreciation expense. Also, increased regulatory focus could lead to higher costs in the future. We are limited in our ability to reduce fixed costs quickly in response to reduced demand for our products and these fixed costs may not be fully absorbed, resulting in higher average unit costs and lower gross margins if we are not able to offset this higher unit cost with price increases. Alternatively, we may be limited in our ability to quickly respond to unanticipated increased demand for our products, which could result in an inability to satisfy demand for our products and loss of market share.

We may be subject to liability under and may make substantial future expenditures to comply with environmental laws and regulations.

Our manufacturing facilities are subject to numerous foreign, federal, state and local laws and regulations relating to the presence of hazardous materials, pollution and the protection of the environment, including those governing emissions to air, discharges to water, use, storage and transport of hazardous materials, storage, treatment and disposal of waste, remediation of contaminated sites and protection of worker health and safety.

Liability under these laws involves inherent uncertainties. Violations of environmental, health and safety laws are subject to civil, and, in some cases, criminal sanctions. As a result of these uncertainties, we may incur unexpected interruptions to operations, fines, penalties or other reductions in income which could adversely impact our business, financial condition and results of operations. Continued and increased government and public emphasis on environmental issues is expected to result in increased future investments for environmental controls at ongoing operations, which will be charged against income from future operations. Present and future environmental laws and regulations applicable to our operations, and changes in their interpretation, may require substantial capital expenditures or may require or cause us to modify or curtail our operations, which may have a material adverse impact on our business, financial condition and results of operations.

-10-

ITEM 1A.

RISK FACTORS (continued)

We are subject to risks associated with our international operations.

We sell products and operate plants throughout the world. Our international sales and operations are subject to risks and uncertainties, including:

•

possible government legislation;

•

difficulties and costs associated with complying with a wide variety of complex laws, treaties and regulations;

•

unexpected changes in regulatory environments;

•

economic and political conditions;

•

tax rates that may exceed those in the United States;

•

tax inefficiencies and currency exchange controls that may adversely impact our ability to repatriate cash from non-United States subsidiaries;

•

the imposition of tariffs or other import or export restrictions;

•

costs and availability of shipping and transportation;

•

nationalization of properties by foreign governments; and

•

currency exchange rate fluctuations between the United States dollar and foreign currencies.

As we continue to expand our business globally, we may have difficulty anticipating and effectively managing these and other risks that our international operations may face, which may adversely impact our business outside the United States and our financial condition and results of operations.

If our efforts in acquiring and integrating other businesses, establishing joint ventures or expanding our production capacity are not successful, our business may not grow.

We may face difficulties associated with growing our business through acquisitions, joint ventures or the expansion of our production capacity. Our ability to grow our business through these investments depends upon our ability to identify, negotiate and finance suitable arrangements. If we cannot successfully execute on our investments on a timely basis, we may be unable to generate sufficient revenue to offset acquisition, integration or expansion costs, we may incur costs in excess of what we anticipate, and our expectations of future results of operations, including cost savings and synergies, may not be achieved. Acquisitions, joint ventures and production capacity expansions involve substantial risks, including:

•

unforeseen difficulties in operations, technologies, products, services, accounting and personnel;

•

diversion of financial and management resources from existing operations;

•

unforeseen difficulties related to entering geographic regions or markets where we do not have prior experience;

•

risks relating to obtaining sufficient equity or debt financing;

-11-

ITEM 1A.

RISK FACTORS (continued)

•

potential loss of key employees; and

potential loss of customers.

Our failure to address these risks or other problems encountered in connection with our past or future acquisitions and investments could cause us to fail to realize the anticipated benefits of such acquisitions or investments, incur unanticipated liabilities, and harm our business generally. Future acquisitions and investments could also result in dilutive issuances of our equity securities, the incurrence of debt, contingent liabilities, or amortization expenses, or write-offs of goodwill, any of which could harm our financial condition. Also, the anticipated benefits of our investments may not materialize.

Our intellectual property rights may not provide meaningful commercial protection for our products or brands, which could adversely impact our business.

Owens Corning relies on its proprietary intellectual property, including numerous registered trademarks, as well as its licensed intellectual property. We monitor and protect against activities that might infringe, dilute, or otherwise harm our patents, trademarks and other intellectual property and rely on the patent, trademark and other laws of the United States and other countries. However, we may be unable to prevent third parties from using our intellectual property without our authorization. To the extent we cannot protect our intellectual property, unauthorized use and misuse of our intellectual property could harm our competitive position and have a material adverse impact on our business, financial condition and results of operations. In addition, the laws of some non-United States jurisdictions provide less protection for our proprietary rights than the laws of the United States. If we are unable to maintain certain exclusive licenses, our brand recognition could be adversely impacted.

We could face potential product liability claims, we may not accurately estimate costs related to such claims, and we may not have sufficient insurance coverage available to cover product liability claims.

Our products are used and have been used in a wide variety of residential and commercial applications. We face an inherent business risk of exposure to product liability or other claims in the event our products are alleged to be defective or that the use of our products is alleged to have resulted in harm to others or to property. We may in the future incur liability if product liability lawsuits against us are successful. Moreover, any such lawsuits, whether or not successful, could result in adverse publicity to us, which could cause our sales to decline.

In addition, consistent with industry practice, we provide warranties on many of our products and we may experience costs of warranty or breach of contract claims if our products have defects in manufacture or design or they do not meet contractual specifications. We estimate our future warranty costs based on historical trends and product sales, but we may fail to accurately estimate those costs and thereby fail to establish adequate warranty reserves for them. We maintain insurance coverage to protect us against product liability claims, but that coverage may not be adequate to cover all claims that may arise or we may not be able to maintain adequate insurance coverage in the future at an acceptable cost. Any liability not covered by insurance or that exceeds our established reserves could materially and adversely impact our financial condition and results of operations.

We are subject to litigation in the ordinary course of business and uninsured judgments or a rise in insurance premiums may adversely impact our results of operations.

In the ordinary course of business, we are subject to various claims and litigation. Any such claims, whether with or without merit, could be time consuming and expensive to defend and could divert management’s attention and resources. In accordance with customary practice, we maintain insurance against some, but not all, of these potential claims. We may elect not to obtain insurance if we believe that the cost of available insurance is

-12-

ITEM 1A.

RISK FACTORS (continued)

excessive relative to the risks presented. The levels of insurance we maintain may not be adequate to fully cover any and all losses or liabilities. Further, we may not be able to maintain insurance at commercially acceptable premium levels or at all. If any significant accident, judgment, claim or other event is not fully insured or indemnified against, it could have a material adverse impact on our business, financial condition and results of operations. We cannot assure that the outcome of all current or future litigation will not have a material adverse impact on the Company and its results of operations.

We depend on our senior management team and other skilled and experienced personnel to operate our business effectively, and the loss of any of these individuals could adversely impact our business and our future financial condition or results of operations.

We are highly dependent on the skills and experience of our senior management team and other skilled and experienced personnel. These individuals possess sales, marketing, manufacturing, logistical, financial, business strategy and administrative skills that are important to the operation of our business. The loss of any of these individuals or an inability to attract, retain and maintain additional personnel could prevent us from implementing our business strategy and could adversely impact our business and our future financial condition or results of operations. We cannot assure that we will be able to retain all of our existing senior management personnel or to attract additional qualified personnel when needed.

Increases in the cost of labor, union organizing activity, labor disputes and work stoppages at our facilities could delay or impede our production, reduce sales of our products and increase our costs.

The costs of labor are generally increasing, including the costs of employee benefit plans. We are subject to the risk that strikes or other types of conflicts with personnel may arise or that we may become the subject of union organizing activity at additional facilities. In particular, renewal of collective bargaining agreements typically involves negotiation, with the potential for work stoppages or increased costs at affected facilities. Currently, all of our union employees are covered by collective bargaining agreements.

Downgrades of our credit ratings could adversely impact us.

Our credit ratings are important to our cost of capital. The major debt rating agencies routinely evaluate our debt based on a number of factors, which include financial strength as well as transparency with rating agencies and timeliness of financial reporting. A downgrade in our debt rating could result in increased interest and other expenses on our existing variable interest rate debt, and could result in increased interest and other financing expenses on future borrowings. Downgrades in our debt rating could also restrict our access to capital markets and affect the value and marketability of our outstanding notes.

We will not be insured against all potential losses and could be seriously harmed by natural disasters, catastrophes or sabotage.

Many of our business activities involve substantial investments in manufacturing facilities and many products are produced at a limited number of locations. These facilities could be materially damaged by natural disasters such as floods, tornados, hurricanes and earthquakes or by sabotage. We could incur uninsured losses and liabilities arising from such events, including damage to our reputation, and/or suffer material losses in operational capacity, which could have a material adverse impact on our business, financial condition and results of operations.

RISKS RELATED TO OWNERSHIP OF OUR COMMON STOCK

The market price of our common stock is subject to volatility.

The market price of our common stock could be subject to wide fluctuations in response to numerous factors, many of which are beyond our control. These factors include actual or anticipated variations in our operational

-13-

ITEM 1A.

RISK FACTORS (continued)

results and cash flow, our earnings relative to our competition, changes in financial estimates by securities analysts, trading volume, sales by holders of large amounts of our common stock, short selling, market conditions within the industries in which we operate, seasonality of our business operations, the general state of the securities markets and the market for stocks of companies in our industry, governmental legislation or regulation and currency and exchange rate fluctuations, as well as general economic and market conditions, such as recessions.

A small number of our stockholders could be able to significantly influence our business and affairs.

A few financial institutions and the Asbestos Personal Injury Trust formed as part of the Predecessor’s emergence from Chapter 11 bankruptcy proceedings in 2006 (the “Asbestos PI Trust”) own substantial amounts of our outstanding common stock. Large holders, such as these parties, may be able to affect matters requiring approval by our stockholders, including the election of directors and the approval of mergers or other business combination transactions. In addition, our bylaws give the Asbestos PI Trust the right to nominate two directors for as long as it holds shares representing at least 1% of our common stock.

We are a holding company with no operations of our own and depend on our subsidiaries for cash.

We are a holding company and most of our assets are held by our direct and indirect subsidiaries and we will primarily rely on dividends and other payments or distributions from our subsidiaries to meet our debt service and other obligations and to enable us to pay dividends. The ability of our subsidiaries to pay dividends or make other payments or distributions to us will depend on their respective operating results and may be restricted by, among other things, the laws of their jurisdiction of organization (which may limit the amount of funds available for the payment of dividends or other payments), agreements of those subsidiaries, agreements with any co-investors in non-wholly-owned subsidiaries, the terms of our credit facility and senior notes and the covenants of any future outstanding indebtedness we or our subsidiaries may incur.

Provisions in our amended and restated certificate of incorporation and bylaws or Delaware law might discourage, delay or prevent a change in control of our company or changes in our management and therefore depress the trading price of our common stock.

Our amended and restated certificate of incorporation and bylaws contain provisions that could depress the trading price of our common stock through provisions that may discourage, delay or prevent a change in control of our company or changes in our management that our stockholders may deem advantageous. These provisions:

•

require a 75% super-majority vote to amend some provisions in our amended and restated certificate of incorporation and bylaws;

•

require approval of the Asbestos PI Trust with respect to the amendment of certain provisions in our amended and restated certificate of incorporation and bylaws, if the amendment could adversely impact certain rights granted to the Asbestos PI Trust;

•

authorize the issuance of “blank check” preferred stock that our Board of Directors has a restricted right to issue to increase the number of outstanding shares to discourage a takeover attempt;

•

create a staggered Board of Directors;

•

prohibit stockholder action by written consent, and require that all stockholder actions be taken at a meeting of our stockholders;

•

provide that the Board of Directors is expressly authorized to make, amend or repeal our bylaws except in limited circumstances; and

•

establish advance notice requirements for nominations for elections to our Board of Directors or for proposing matters that can be acted upon by stockholders at stockholder meetings.

RISK FACTORS (continued)

Additionally, we are subject to Section 203 of the Delaware General Corporation Law, which generally prohibits a Delaware corporation from engaging in any of a broad range of business combinations with any “interested” stockholder for a period of three years following the date on which the stockholder became an “interested” stockholder and which may discourage, delay or prevent a change in control of our company.

We may pay no cash dividends on our common stock.

The payment of any future cash dividends to our stockholders will depend on decisions that will be made by our Board of Directors and will depend on then existing conditions, including our operating results, financial conditions, contractual restrictions, corporate law restrictions, capital agreements, applicable laws of the State of Delaware and business prospects. We may pay no cash dividends for the foreseeable future.

LEGAL PROCEEDINGS

On September 1, 2006, various members of the Investment Review Committee of the Predecessor were named as defendants in a lawsuit captioned Brown v. Owens Corning Investment Review Committee, et al., in the United States District Court for the Northern District of Ohio (Western Division). Neither the Company nor the Predecessor is named in the lawsuit but such individuals would have a contingent indemnification claim against the Predecessor. The suit, brought by former employees of the Predecessor, was brought under ERISA alleging that the defendants breached their fiduciary duties to certain pension benefit plans and to class members in connection with the investments in a Predecessor company common stock fund. A motion to dismiss was filed on behalf of the defendants on March 5, 2007. Subsequently, the court converted the Motion to Dismiss to a Motion for Summary Judgment. On March 31, 2008, the court denied the defendants’ Motion for Summary Judgment. On April 15, 2008, the defendants filed a Motion for Reconsideration. On December 24, 2008, the court granted the defendants’ Motion for Reconsideration and dismissed the action. On January 9, 2009, the plaintiffs filed a Motion to Amend Judgment. On February 6, 2009, the defendants filed an Opposition to Plaintiff’s Motion to Amend Opinion and Order of Judgment. On June 3, 2009, the plaintiffs filed a Notice of Appeal in the United States Court of Appeals for the Sixth Circuit. Oral argument was held on March 11, 2010. On September 27, 2010, the United States Court of Appeals for the Sixth Circuit affirmed the judgment of the United States District Court.

Certain of the defendants in the lawsuit described above are officers or directors of the Company.

Cash Dividends

Owens Corning did not pay cash dividends on its common stock during the two most recent years. The payment of any future cash dividends to our stockholders will depend on decisions that will be made by our Board of Directors and will depend on then existing conditions, including our operating results, financial condition, contractual restrictions, corporate law restrictions, capital requirements, the applicable laws of the State of Delaware and business prospects. Although our Board of Directors is expected to consider from time to time the payment of quarterly cash dividends, there can be no assurance we will pay any cash dividend, or if declared, the amount of such cash dividend.

As a consequence of certain provisions of the Company’s senior notes and senior credit facilities, the Company and its subsidiaries are subject to certain restrictions on their ability to pay dividends and to transfer cash and other assets to each other and to their affiliates.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

This Management’s Discussion and Analysis (“MD&A”) is intended to help the reader understand Owens Corning, our operations and our present business environment. MD&A is provided as a supplement to – and should be read in conjunction with – our Consolidated Financial Statements and the accompanying Notes thereto contained in this report. Unless the context requires otherwise, the terms “Owens Corning,” “Company,” “we” and “our” in this report refer to Owens Corning.

GENERAL

Owens Corning is a leading global producer of glass fiber reinforcements and other materials for composites and of residential and commercial building materials. The Company’s business operations fall within two reportable segments, Composites and Building Materials. Composites includes our Reinforcements and Downstream businesses. Building Materials includes our Insulation, Roofing and Other businesses. Through these lines of business, we manufacture and sell products worldwide. We maintain leading market positions in many of our major product categories.

EXECUTIVE OVERVIEW

In 2010, we generated $381 million in adjusted earnings before interest and taxes, despite continued weakness in many of our end markets, and $933 million in net earnings attributable to Owens Corning, driven by the reversal of a valuation allowance against certain of the Company’s United States deferred tax assets.

The diversity of our portfolio of businesses served us well. Our Composites segment grew EBIT by $208 million for the year as the business delivered significant operating leverage on higher global demand. Despite weak U.S. markets in our Building Materials segment, we were able to sustain strong performance in our Roofing business and improve selling prices in our Insulation business. See below for further information regarding Adjusted EBIT, including a reconciliation to net earnings (loss) attributable to Owens Corning.

In our Composites segment, the positive trend in demand demonstrated during 2009 continued throughout 2010 leading to an increase in sales of 17 percent over 2009. The higher level of global demand, which supported increased utilization of our production capacity and favorable pricing, drove a $208 million improvement in EBIT over 2009 for the segment.

In our Building Materials segment, our Roofing business continued to perform well and delivered EBIT margins of 22 percent, despite the United States market demand for roofing shingles being down approximately 10 percent in 2010 compared to 2009. In the Insulation business, challenging market conditions more than offset our pricing actions and disciplined capacity management.

During 2010, we continued our focus on generating cash and maintaining a strong balance sheet with ample liquidity. We generated $488 million in cash flow from operating activities. These results are primarily due to the performance of our Composites segment and Roofing business as well as our favorable tax position.

We repurchased 4.2 million shares of the Company’s stock for $117 million during the year under previously announced share repurchase programs. As of December 31, 2010, we have 7.7 million shares available for repurchase under the remaining program.

At the end of 2010, we had $739 million available on our $800 million senior revolving credit facility, and cash on hand of $52 million. As a result of our refinancing in the second quarter 2010, we have no significant debt maturities until 2014.

The Consolidated Results discussion below provides a summary of our results and the trends affecting our business, and should be read in conjunction with the more detailed Segment Results discussion that follows.

NET SALES

2010 Compared to 2009: Net sales increased in 2010 as compared to 2009, driven by higher net sales in our Composites segment. This increase was partially offset by lower net sales across our Building Materials segment as a result of overall weakness within these markets.

2009 Compared to 2008: Net sales decreased in 2009 as compared to 2008, driven by lower net sales in our Composites segment and in our Insulation business. Overall demand for our products was lower in 2009 as a result of continued weakness in the United States housing market and the global economy.

GROSS MARGIN

2010 Compared to 2009: Gross margin as a percentage of sales improved in 2010 as compared to 2009. This improvement was primarily the result of gross margin improvements in our Composites business. The increase in gross margin percentage was tempered by margin declines in our Roofing business. Despite this decline, the business still delivered EBIT margins in excess of 20 percent for the year.

2009 Compared to 2008: Gross margin as a percentage of sales improved in 2009 as compared to 2008. This improvement was primarily the result of significant gross margin improvements in our Roofing business, coupled with our Roofing business representing a greater proportion of gross margin in 2009. The overall increase in gross margin as a percentage of sales was tempered by margin declines in our Insulation business and our Composites segment.

CHARGES RELATED TO COST REDUCTION ACTIONS

2010 Compared to 2009: Charges related to cost reduction actions were lower in 2010 compared to 2009. During 2010, as part of our continuing review of our manufacturing network, we took actions to further balance global capacity and respond to market conditions.

2009 Compared to 2008: Charges related to cost reduction actions were higher in 2009 compared to 2008. During 2009, we took significant actions to reduce production and lower operating costs in response to weak market conditions, resulting in severance charges.

EMPLOYEE EMERGENCE EQUITY PROGRAM EXPENSE

2010 Compared to 2009: As part of our 2006 emergence from bankruptcy, we established a one-time employee emergence equity program. The cost of this program was amortized over a vesting period of three years beginning in November 2006. The cost related to this program was fully amortized by the end of 2009.

EARNINGS BEFORE INTEREST AND TAXES

2010 Compared to 2009: In addition to the items noted above, year-over-year comparability of earnings before interest and taxes were impacted by the sale of Masonry Products, which resulted in total charges of $114 million, and other indefinite lived asset impairment charges of $10 million in 2010 which was recorded as other expenses (income) on the Consolidated Statements of Earnings (Loss).

2009 Compared to 2008: In addition to the items noted above, year-over-year comparability of earnings before interest and taxes were impacted by gains on sales of certain precious metals used in production tooling. In 2009, we recorded a $6 million gain on the sale of certain precious metals used in production tooling. In 2008, we recorded gains of $48 million on such sales. These items were recorded in other expenses (income) on the Consolidated Statements of Earnings (Loss).

INTEREST EXPENSE, NET

2010 Compared to 2009: Interest expense was generally flat between 2010 and 2009.

2009 Compared to 2008: Interest expense in 2009 was in line with that of 2008. Higher average borrowing levels in 2009 were offset by lower weighted-average interest rates.

INCOME TAX EXPENSE

Income tax benefit for 2010 was $840 million. The income tax benefit was the result of reversing $937 million of the valuation allowance primarily related to the Company’s United States federal and state deferred tax assets. The valuation allowance was originally established in 2008 based primarily on negative evidence of the Company’s losses before income taxes in the United States during 2007 and 2008. Other negative evidence considered at the time was the Company’s then estimates for near-term results in the United States. Financial performance in the United States during that time period was adversely impacted by the decline in United States housing starts. Since that time, earnings performance in our United States operations has strengthened and has resulted in positive cumulative earnings in recent years as of June 30, 2010, which was the primary evidence used in determining to reverse the valuation allowance in the second quarter. Other positive evidence considered was the Company’s forecast, which indicates the Company’s positive earnings trend will continue in the long-term.

After the removing the effect of valuation allowances during 2010, the effective tax rate was 69%. The difference between the 69% effective tax rate and the statutory tax rate of 35% is primarily attributable to increases in global tax reserves and the impact of the goodwill impairment. The effective rate was decreased by the benefit of lower foreign tax rates and various tax planning initiatives, which have significantly reduced our cash taxes and tax provision related to our international operations.

Income tax expense for 2009 was $14 million. The difference between the effective tax rate in 2009 of 17% and the statutory tax rate of 35% is primarily attributable to the increased level of earnings in the United States, in which there is relatively little income tax expense due to the valuation allowance against the United States deferred tax assets. Also contributing to the lower effective tax rate are the various tax planning initiatives implemented in 2007 and 2008, which have significantly reduced our cash taxes and tax provision related to our

-25-

ITEM 7.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (continued)

international operations. Offsetting the reductions were increases to the valuation allowance related to our international operations and increases in other tax reserves.

Income tax expense for 2008 was $931 million primarily due to a non-cash charge of $906 million to establish an accounting valuation allowance against our United States deferred tax assets, related to our net operating losses. After the removing the effect of valuation allowances during 2008, the effective tax rate was 15%. The difference between this effective rate and the federal statutory tax rate of 35% was primarily attributable to various tax planning initiatives implemented in 2007 through 2008 which have significantly reduced our cash taxes and tax provision related to our international operations.

Adjusted Earnings Before Interest and Taxes (“Adjusted EBIT”)

Adjusted EBIT excludes certain items that management does not allocate to our segment results because it believes they are not a result of the Company’s current operations. Additionally, management views net precious metal lease expense as a financing item included in net interest expense rather than as a product cost included in cost of sales. Adjusted EBIT is used internally by the Company for various purposes, including reporting results of operations to the Board of Directors of the Company, analysis of performance and related employee compensation measures. Although management believes that these adjustments result in a measure that provides it a useful representation of our operational performance, the adjusted measure should not be considered in isolation or as a substitute for net earnings (loss) attributable to Owens Corning as prepared in accordance with accounting principles generally accepted in the United States.

Segment Results

Earnings before interest and taxes (“EBIT”) by segment consists of net sales less related costs and expenses and are presented on a basis that is used internally for evaluating segment performance. Certain items, such as general corporate expenses or income and certain other expense or income items, are excluded from the internal evaluation of segment performance. Accordingly, these items are not reflected in EBIT for our reportable segments and are included in the Corporate, Other and Eliminations category, which is presented following the discussion of our reportable segments.

Composites

The table below provides a summary of net sales, EBIT and depreciation and amortization expense for our Composites segment (in millions):


	Twelve Months Ended Dec. 31,
	2010			2009			2008
Net sales	$	1,906		$	1,633		$	2,363

Depreciation and amortization expense	$	117		$	117		$	138

NET SALES

2010 Compared to 2009: Substantially all of the increase in net sales was due to higher sales volumes as global demand improved in 2010. Increases in selling prices also improved net sales for the year. The upward trend in selling prices that began in the fourth quarter 2008 continued during the fourth quarter 2010. As a result, selling prices for all markets within our Reinforcements business at the end of 2010 are approaching levels seen prior to the 2008 global economic downturn.

2009 Compared to 2008: Lower sales volumes, resulting from reduced demand levels, represented approximately two-thirds of the decrease in net sales for 2009 as compared to 2008. The remainder of the decrease in net sales was the result of the inclusion of four months of sales from the 2008 divestiture of certain European manufacturing facilities in 2008 net sales, unfavorable product mix, lower selling prices and unfavorable currency translation.

EBIT

2010 Compared to 2009: EBIT in our Composites segment was $208 million higher in 2010 than in 2009. More than three-fourths of the improvement was driven by higher sales volumes, including the impact of improved utilization of our production capacity. As a result of improvements in demand and actions we took during 2009, our capacity utilization at the end of 2010 was in-line with the high levels seen in the first three quarters of 2008. Higher selling prices accounted for the remainder of the increase. These improvements resulted in Composites achieving 12 percent EBIT margin for the fourth quarter of 2010.

2009 Compared to 2008: Our Composites segment EBIT was $241 million lower in 2009 than in 2008. The decline was primarily driven by lower sales volumes, including the impact of underutilization of our production capacity. Also impacting EBIT for our Composites segment were lower selling prices, partially offset by lower marketing and administrative expenses.

OUTLOOK

We believe that demand in this segment will grow as global industrial demand increases. However, the rate and extent of the market growth is expected to vary among products, end-use markets and geographic regions. Our new Reinforcements facility in China has begun operations and will contribute to segment profitability in 2011.

Building Materials

The table below provides a summary of net sales, EBIT and depreciation and amortization expense (in millions) for the Building Materials segment and our businesses within this segment. Changes have been made to reflect the sale of Masonry Products. Prior period amounts have been recast to reflect the inclusion of the Construction Services and Building Materials Europe businesses within Insulation. Other primarily consists of Masonry Products:

NET SALES

2010 Compared to 2009: Net sales in our Building Materials segment were lower in 2010, primarily due to lower net sales in our Roofing business.

In our Roofing business, 2010 net sales were down slightly from 2009. Nearly all of the decrease in net sales for 2010 as compared to the same period 2009 was due to lower sales volumes. Weakness in market demand that began late in the second quarter 2010 persisted throughout the remainder of the year. Selling prices for our roofing shingle products were down slightly in 2010 as compared to 2009. However, this was offset by increases in selling prices to our external asphalt customers. Selling prices of our roofing products have been relatively stable since the fourth quarter 2008, with some fluctuation quarter to quarter.

-28-

ITEM 7.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (continued)

In our Insulation business, net sales were relatively stable year-over-year. Higher selling prices, and the impact of foreign currency translation, were offset by lower sales volumes. Our Insulation business includes a diverse portfolio with a geographic mix of United States, Canada, Asia-Pacific and Latin America, a market mix of residential, commercial, industrial and other markets, and a channel mix of retail, contractor and distribution. The lower sales volumes in 2010 were driven by the absence of demand from the 2009 Australian stimulus and broad weakness in our end markets, predominantly in our retail channels.

2009 Compared to 2008: Net sales in our Building Materials segment were lower in 2009, primarily driven by demand weakness resulting from lower United States housing starts.

Sales in our Roofing business were comparable year-over-year, as higher selling prices offset lower sales volumes. We increased selling prices in our Roofing business in the months leading up to the fourth quarter 2008 to recover inflation in raw material costs, particularly asphalt. Since that time, selling prices have been generally stable. Lower demand, associated with both reduced storm activity and reduced new residential construction, resulted in the lower level of sales volumes and decreased net sales by approximately 10 percent.

In our Insulation business, lower sales volumes represented more than three-fourths of the decline in net sales. Demand was down primarily as a result of the lower level of housing starts. Our experience is that our residential insulation demand lags United States residential housing starts by approximately three months. Lagged United States housing starts for 2009 (the period from October 1, 2008 through September 30, 2009) were 43 percent lower than those for the same period one year earlier according to data reported by the United States Census Bureau. In aggregate, the diverse portfolio within our insulation business moderated the impact of lower United States housing starts on overall Insulation demand.

EBIT

2010 Compared to 2009: Substantially all of the decrease in EBIT during the year is the result of lower profitability within the Roofing business.

In our Roofing business, unit margins were lower due to higher raw material costs, particularly asphalt, and slightly lower selling prices. This accounted for more than three-fourths of the year-over-year decrease in EBIT. During 2010, the business improved EBIT due to manufacturing productivity improvements, primarily in material cost take out. However, these gains were more than offset by lower volumes that resulted from market weakness that began in the second quarter 2010.

In our Insulation business, EBIT was relatively flat in 2010 compared to 2009. Higher selling prices and favorable product mix increased EBIT by more than $40 million from 2009. This impact was offset by lower sales volumes, including underutilization of our production capacity, and material inflation.

2009 Compared to 2008: The substantial increase in EBIT was driven by unit margin improvements in our Roofing business, which were partially offset by lower EBIT performance in the rest of the Building Materials segment.

In our Roofing business, higher unit margins accounted for substantially all of the increase in EBIT. The EBIT margin momentum from the fourth quarter 2008 continued throughout 2009 as a result of generally stable selling prices and deflation in certain raw materials costs, primarily asphalt. Partially offsetting the higher unit margins was the impact of lower sales volumes, including underutilization of our production capacity.

In our Insulation business, lower sales volumes, including the impact of underutilization of our production capacity, accounted for substantially all of the decrease in EBIT. Other items impacting EBIT were slightly lower

-29-

ITEM 7.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (continued)

selling prices, which were offset by improved manufacturing productivity, deflation in raw materials costs and lower marketing and administrative expenses.

OUTLOOK

Fourth quarter 2010 United States housing starts were generally flat from the fourth quarter 2009, and therefore we expect new residential construction related market demand in our Building Materials segment to be relatively flat in the first quarter 2011. As compared to the first quarter 2010, we expect overall demand weakness to continue through at least the first half 2011, as the timing and pace of any recovery of the United States housing market in 2011 remains uncertain.

In our Roofing business, we have sustained significant margin improvements over recent years through price discipline and gains in manufacturing productivity and material efficiencies. We expect that these margin improvements we have made will continue to drive profitability despite weak demand. Uncertainties that may impact our Roofing gross margins include competitive pricing pressure and the cost and availability of raw materials, particularly asphalt.

In our Insulation business, we believe the geographic, product, and channel mix of our portfolio will help moderate the impact of continued demand-driven weakness associated with new construction in 2011. Should the recovery of new construction be sooner and faster than anticipated, we are prepared to respond to increased demand by bringing additional production capacity back on-line. Conversely, we are prepared to take further actions to reduce our production if further weakening occurs.

Corporate, Other and Eliminations

The table below provides a summary of EBIT and depreciation and amortization expense for the Corporate, Other and Eliminations category (in millions):

2010 Compared to 2009: During 2010 we recorded $124 million in charges related to the sale of Masonry Products and the impairment of other indefinite lived intangible assets. See Note 5 and 9 to the Consolidated Financial Statements for items included in gains (losses) on sale of assets and related items. Acquisition integration and transaction costs were lower in 2010 than 2009 as integration work associated with the 2007 Acquisition was completed. Our employee emergence equity was fully amortized in 2009. See Note 14 to the

ITEM 7.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (continued)

Consolidated Financial Statements for charges related to cost reduction actions and related items. General corporate expense for 2010 was driven by increased foreign currency transaction losses and other general corporate expenses.

2009 Compared to 2008: During 2009, we took significant actions to reduce production and lower operating costs in response to weak market conditions, resulting in severance and other related charges of $53 million. Acquisition integration and transaction costs were lower in 2009 than 2008 because the majority of the integration work was completed before 2009 and the 2008 charges include a $10 million impairment related to the 2008 Divestiture. In 2009, we recorded a $6 million gain on the sale of certain precious metals used in production tooling, while in 2008, we recorded gains of $48 million on such sales.

SAFETY

Working safely is a condition of employment at Owens Corning. We believe this organization-wide expectation provides for a safer work environment for employees, improves our manufacturing processes, reduces our costs and enhances our reputation. Furthermore, striving to be a world-class leader in safety provides a platform for all employees to understand and apply the resolve necessary to be a high-performing, global organization. We measure our progress on safety based on Recordable Incidence Rate (“RIR”) as defined by the United States Department of Labor, Bureau of Labor Statistics. Our full year performance improved 23% in 2010 over our performance in 2009.

LIQUIDITY, CAPITAL RESOURCES AND OTHER RELATED MATTERS

Liquidity

We have an $800 million senior revolving credit facility, which does not mature until May of 2014 and serves as our primary source of liquidity. During 2010, we repaid the $600 million term loan and refinanced the prior senior revolving credit facility. We have no other significant debt maturities before 2014. As of December 31, 2010, we had $739 million available on the senior revolving credit facility and $1.6 billion of total debt and cash-on-hand of $52 million.

We expect that our cash on hand, coupled with future cash flows from operations and other available sources of liquidity, including our senior revolving credit facility, will provide ample liquidity to allow us to meet our cash requirements. Our anticipated uses of cash include capital expenditures, working capital needs, pension contributions, meeting financial obligations and reducing outstanding amounts under the senior credit facility. We have an outstanding share repurchase authorization and will evaluate and consider repurchasing shares of our common stock as well as strategic acquisitions, divestitures, joint ventures and other transactions to create stockholder value and enhance financial performance. Such transactions may require cash expenditures beyond current sources of liquidity or generate proceeds.

While the economic environment has greatly improved, we are closely monitoring the potential impact of changes in the operating conditions of our customers on our operating results. To date, changes in the operating conditions of our customers have not had a material adverse impact on our operating results; however, it is possible that we could experience material losses in the future if current economic conditions continue or worsen.

The credit agreement applicable to our senior revolving credit facility contains various covenants, including a maximum allowed leverage ratio and a minimum required interest expense coverage ratio that we believe are usual and customary for agreements of this type. We were well within compliance with these covenants as of December 31, 2010.

ITEM 7.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (continued)

Cash flows

The following table presents a summary of our cash balance and cash flows (in millions):


	Twelve Months Ended Dec. 31,
	2010			2009			2008
Cash balance	$	52		$	564		$	236
Cash provided by operating activities	$	488		$	541		$	193
Cash used for investing activities	$	(249	)	$	(204	)	$	(162	)
Cash provided by (used for) financing activities	$	(750	)	$	(17	)	$	67
Unused committed credit lines	$	739		$	946		$	615

Operating activities: In 2010, we generated $488 million of cash from operating activities compared to $541 million in 2009. Composites earnings performance in 2010 partially offset the $134 million of working capital reductions that we were able to achieve in 2009.

Investing activities: The increase in cash used for investing activities in 2010 compared to 2009 is the result of additional capital expenditures. In 2010 we spent $314 million in capital expenditures, which included our new Reinforcement facility in China as compared to $243 million in 2009. This was partially offset by higher proceeds received from the sale of assets during 2010, primarily driven by the sale of Masonry Products.

Financing activities: In 2010, we used $733 million more in financing activities than in 2009. This change was primarily due to the repayment of our $600 million senior term loan and the repurchase of 4.2 million shares of the Company’s stock for $117 million during 2010.

2011 Investments

Capital Expenditures: The Company will continue a balanced approach to the use of its cash flow. Operational cash flow will be used to fund the Company’s growth and innovation. Capital expenditures in 2011 are expected to be greater than depreciation and amortization. The Company will also continue to evaluate projects and acquisitions that provide opportunities for growth in our businesses, and invest in them when they meet our strategic and financial criteria.

Tax Net Operating Losses

Upon emergence and subsequent distribution of contingent stock and cash in January 2007, we generated a significant United States federal tax net operating loss of approximately $3.0 billion. As of December 31, 2010, our federal tax net operating losses remaining were $2.4 billion. Our net operating losses are subject to the limitations imposed under section 382 of the Internal Revenue Code. These limits are triggered when a change in control occurs, and are computed based upon several variable factors including the share price of the Company’s common stock on the date of the change in control. A change in control is generally defined as a cumulative change of 50% or more in the ownership positions of certain stockholders during a rolling three year period. Our initial three year period for measuring an ownership change started at October 31, 2006.

As discussed previously, the Company reversed $937 million of valuation allowance primarily related to its United States federal and state deferred tax assets. This reversal was the result of our strong earnings performance in our United States operations during 2009 and the first half of 2010, as well as favorable forecasts. The reversal of this valuation allowance has no impact on our cash flow or liquidity.

-32-

ITEM 7.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (continued)

In addition to the United States net operating losses described above, we have net operating losses in various foreign jurisdictions, which totaled $552 million as of December 31, 2010. Our ability to utilize these net operating losses may be limited as a result of certain events, such as insufficient future taxable income prior to expiration of the net operating losses. Should we determine that it is likely that our recorded net operating loss benefits are not realizable, we would be required to reduce the net operating loss tax benefits reflected on our Consolidated Financial Statements to the net realizable amount by establishing an accounting valuation allowance and recording a corresponding charge to current earnings. To date, we have recorded valuation allowances against certain of these deferred tax assets.

Pension contributions

The Company has several defined benefit pension plans. The Company made cash contributions of $32 and $43 million to the plans during the twelve months ended December 31, 2010 and 2009, respectively. The Company expects to contribute $112 million in cash to its pension plans during 2011. Actual contributions to the plans may change as a result of a variety of factors, including changes in laws that impact funding requirements. The ultimate cash flow impact to the Company, if any, of the pension plan liability and the timing of any such impact will depend on numerous variables, including future changes in actuarial assumptions, legislative changes to pension funding laws, and market conditions.

Derivatives

To mitigate some of the near-term volatility in our earnings and cash flows, we use financial and derivative instruments to manage certain exposures, principally energy- and interest-related. Going forward, the results of these practices could be positive, neutral or negative in any period depending on relevant price changes.

Our policy is to hedge up to 75% of our total forecasted natural gas exposures for the next two months, up to 50% for the following four months, and lesser amounts for the remaining periods. We currently have hedged a portion of our exposures for the next 15 months. These hedges will tend to mitigate near-term volatility in the exposures hedged. The practice is neither intended nor expected to mitigate longer term exposures.

Our current practice is to manage our interest rate exposure by balancing the mixture of our fixed and variable rate instruments. We utilize, among other strategies, interest rate swaps to achieve this balance in interest rate exposures. In 2009, we entered into interest rate swaps to convert $500 million of our fixed rate debt due in 2016 to a variable rate based on LIBOR.

OFF BALANCE SHEET ARRANGEMENTS

The Company has entered into limited off balance sheet arrangements, as defined under Securities and Exchange Commission rules, in the ordinary course of business. These arrangements include a limited amount of unrecorded contingent payment obligations under acquisition purchase agreements which are not material. The Company does not believe these arrangements will have a material effect on the Company’s financial condition, changes in financial condition, revenues or expenses, results of operations, liquidity, capital expenditures or capital resources.

CONTRACTUAL OBLIGATIONS

In the ordinary course of business, the Company enters into contractual obligations to make cash payments to third parties. The Company’s known contractual obligations as of December 31, 2010 are as follows (in millions):


	Payments due by period
	2011		2012		2013		2014		2015		2016 and Beyond		Total
Long-term debt obligations	$	2	$	3	$	3	$	15	$	5	$	1,555	$	1,583
Interest on fixed rate debt		83		83		83		83		83		947		1,362

Total (4)	$	438	$	266	$	244	$	239	$	218	$	2,782	$	4,187

(1)	Interest on variable rate debt is calculated using the weighted-average interest rate in effect as of December 31, 2010 for all future periods including the expected effect of interest rate swaps using the projected market forward interest rate curves.

(2)

Purchase obligations are commitments to suppliers to purchase goods or services, and include take-or-pay arrangements, capital expenditures, and contractual commitments to purchase equipment. We did not include ordinary course of business purchase orders in this amount as the majority of such purchase orders may be canceled and are reflected in historical operating cash flow trends. We do not believe such purchase orders will adversely affect our liquidity position.

(3)	The 2011 pension contributions are based on estimates the Company currently projects contributions to our pension plans will be. For other years presented, contributions represent the minimum amount that the company is required to contribute to the plan.

(4)	The Company has not included its accounting for uncertainty in income taxes liability in the contractual obligation table as the timing of payment, if any, cannot be reasonably estimated. The balance of this liability at December 31, 2010 was $59 million.

CRITICAL ACCOUNTING ESTIMATES

Our discussion and analysis of our financial condition and results of operations is based upon our Consolidated Financial Statements, which have been prepared in accordance with accounting principles generally accepted in the United States. The preparation of these financial statements requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. On an ongoing basis, management evaluates its estimates and judgments related to these assets, liabilities, revenues and expenses. We believe these estimates to be reasonable under the circumstances. Management bases its estimates and judgments on historical experience, expected future outcomes, and on various other factors that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates.

-34-

ITEM 7.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (continued)

We believe that the following accounting estimates are critical to our financial results:

Tax Estimates. The determination of our tax provision is complex due to operations in several tax jurisdictions outside the United States. We apply a more-likely-than-not recognition threshold for all tax uncertainties. Such uncertainties include any claims by the Internal Revenue Service for income taxes, interest, and penalties attributable to audits of open tax years.

In addition, we record a valuation allowance to reduce our deferred tax assets to the amount that we believe is more likely than not to be realized. We estimate future taxable income and the effect of tax planning strategies in our consideration of whether deferred tax assets will more likely than not be realized. In the event we were to determine that we would not be able to realize all or part of our net deferred tax assets in the future, an adjustment to reduce the net deferred tax assets would be charged to earnings in the period such determination was made. Conversely, if we were to determine that we would be able to realize our net deferred tax assets in the future in excess of their currently recorded amount, an adjustment to increase the net deferred tax assets would be credited to earnings in the period such determination was made.

Impairment of Assets. The Company exercises judgment in evaluating assets for impairment. Goodwill and other indefinite-lived intangible assets are tested for impairment annually, or when circumstances arise which indicate there may be an impairment. Long-lived assets are tested for impairment when economic conditions or management decisions indicate an impairment may exist. These tests require comparing recorded values to estimated fair values for the assets under review.

The Company has recorded its goodwill and conducted testing for potential goodwill impairment at a reporting unit level. Our reporting units represent a business for which discrete financial information is available and segment management regularly reviews the operating results. There are 10 reporting units within the Company, with nearly 90% of the goodwill recorded in 2 reporting units within the Building Materials operating segment. Generally, fair values for goodwill testing are estimated using a discounted cash flow approach unless circumstances indicate that a better estimate of fair value is available.

Significant estimates in the discounted cash flow approach are cash flow forecasts of our reporting units, the discount rate, the terminal business value and the projected income tax rate. The cash flow forecasts of the reporting units are based upon management’s long-term view of our markets and are the forecasts that are used by senior management and the Board of Directors to evaluate operating performance. The discount rate utilized is management’s estimate of what the market’s weighted average cost of capital is for a company with a similar debt rating and stock volatility, as measured by beta. The projected income tax rates utilized are the cash tax rates that a prospective buyer would most likely factor into a fair value calculation for each reporting unit. Key factors considered are the statutory rate for the countries where each reporting unit operates and the implementation of a reasonable level of income tax planning strategies. The terminal business value is determined by applying a business growth factor to the latest year for which a forecast exists. Our annual test of goodwill, which was conducted as of October 1, 2010, resulted in no reporting units that were reasonably close to having a carrying value in excess of its fair value, and thus, no impairment charges being required. As part of our goodwill testing process, we evaluate whether there are reasonably likely changes to management’s estimates that would have a material impact on the results of the goodwill impairment testing. For the testing performed in 2010, management concluded that there are no reasonably likely changes that would materially impact the results of the goodwill impairment testing. However, changes in strategic outlook by management on the best use of the company’s asset portfolio or decreases in the Company’s long-term view for any of our reporting units could increase the likelihood of recognizing an impairment charge in the future.

-35-

ITEM 7.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (continued)

Other indefinite-lived intangible assets are the Company’s trademarks. Fair values used in testing for potential impairment of our trademarks are calculated by applying an estimated market value royalty rate to the forecasted revenues of the businesses that utilize those assets. The assumed cash flows from this calculation are discounted back using the Company’s weighted average cost of capital.

Fair values for long-lived asset testing are calculated by estimating the undiscounted cash flows from the use and ultimate disposition of the asset or by estimating the amount that a willing third party would pay. For impairment testing, long-lived assets are grouped at the lowest level for which identifiable cash flows are largely independent of the cash flows of other groups of assets and liabilities. We group long-lived assets based on manufacturing facilities that produce similar products either globally or within a geographic region. Management tests asset groups for potential impairment whenever events or changes in circumstances indicate that the carrying value may not be recoverable. Current market conditions have caused the Company to have idle capacity. We consider such idled capacity to be unimpaired because there has not been a significant change in the forecasted long-term cash flows at the asset group level to indicate that the carrying values may not be recoverable. While management’s current strategy is to utilize this capacity to meet expected future demand, any significant decrease in this expectation or change in management’s strategy could result in future impairment charges related to this excess capacity. We evaluated and concluded that there are not any reasonably likely changes to management’s estimates that would indicate that the carrying value of our long-lived assets is unrecoverable.

In addition, changes in management intentions, market conditions, operating performance and other similar circumstances could affect the assumptions used in these impairment tests. Changes in the assumptions could result in impairment charges that could be material to our Consolidated Financial Statements in any given period.

Pensions and Other Postretirement Benefits. Accounting for pensions and other postretirement benefits involves estimating the cost of benefits to be provided well into the future and attributing that cost over the time period each employee works. To accomplish this, extensive use is made of assumptions about investment returns, discount rates, inflation, mortality, turnover, and medical costs. Changes in assumptions used could result in a material impact to our Consolidated Financial Statements in any given period.

Two key assumptions that could have a significant impact on the measurement of pension liability and pension expense are the discount rate and expected return on plan assets. For our largest plan, the United States plan, the discount rate used for the December 31, 2010 measurement date was derived by matching projected benefit payments to bond yields obtained from the Citigroup Above Median Pension Discount Curve developed at these respective dates. The Citigroup Above Median Pension Discount Curve is a yield curve developed monthly by Citigroup and is based on corporate bonds rated AA+, AA or AA- by Standard & Poor’s or Aa1, Aa2 or Aa3 by Moody’s. The result supported a discount rate of 5.30% at December 31, 2010 compared to 5.80% at the December 31, 2009 measurement date. A 25 basis point increase (decrease) in the discount rate would decrease (increase) the December 31, 2010 projected benefit obligation for the United States pension plans by approximately $30 million. A 25 basis point increase (decrease) in the discount rate would decrease (increase) 2011 net periodic pension cost by approximately $2 million.

-36-

ITEM 7.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (continued)

The expected return on plan assets in the United States was derived by taking into consideration the target plan asset allocation, historical rates of return on those assets, projected future asset class returns and net outperformance of the market by active investment managers. We use the target plan asset allocation because we rebalance our portfolio to target on a quarterly basis. An asset return model was used to develop an expected range of returns on plan investments over a 20 year period, with the expected rate of return selected from a best estimate range within the total range of projected results. This process resulted in the selection of an expected return of 7.75% at the December 31, 2010 measurement date, which is used to determine net periodic pension cost for the year 2011. This assumption is 0.25% lower than the 8.00% return selected at the December 31, 2009 and December 31, 2008 measurement dates. A 25 basis point increase (decrease) in return on plan assets assumption would result in a respective decrease (increase) of 2011 net periodic pension cost by approximately $2 million.

The discount rate for our United States postretirement plan was selected using the same method as described for the pension plan. The result supported a discount rate of 5.05% at December 31, 2010 compared to 5.60% at December 31, 2009. A 25 basis point increase (decrease) in the discount rate would decrease (increase) the United States postretirement benefit obligation by approximately $6 million and decrease (increase) 2011 net periodic postretirement benefit cost by less than $1 million.

The methods corresponding to those described above are used to determine the discount rate and expected return on assets for non-U.S. pension and postretirement plans, to the extent applicable.

ADOPTION OF NEW ACCOUNTING STANDARDS

There were no accounting standards issued during the year that the Company believes would have a material impact on the financial statements.

ITEM 7A.

QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

The Company is exposed to the impact of changes in foreign currency exchange rates, interest rates and the prices of various commodities used in the normal course of business. To mitigate some of the near-term volatility in our earnings and cash flows, the Company manages certain of our exposures through the use of certain financial contracts, contracts for physical delivery of a particular commodity, and derivative financial instruments. The Company’s objective with these instruments is to reduce exposure to fluctuations in earnings and cash flows. The Company’s policy enables the use of foreign currency, interest rate and commodity derivative financial instruments only to the extent necessary to manage exposures as described above. The Company does not enter into such transactions for trading purposes.

A discussion of the Company’s accounting policies for derivative financial instruments, as well as the Company’s exposure to market risk, is included in the Notes to the Consolidated Financial Statements.

For purposes of disclosing the market risk inherent in its derivative financial instruments the Company uses sensitivity analysis disclosures that express the potential loss in fair values of market rate sensitive instruments resulting from changes in interest rates, foreign currency exchange rates, and commodity prices that assume instantaneous, parallel shifts in exchange rates, interest rate yield curves, and commodity prices. The following analysis provides such quantitative information regarding market risk. There are certain shortcomings inherent in the sensitivity analyses presented, primarily due to the assumption that exchange rates change instantaneously and that interest rates change in a parallel fashion. In addition, the analyses are unable to reflect the complex market reactions that normally would arise from the market shifts modeled.

Foreign Exchange Rate Risk

The Company has foreign currency exposures related to buying, selling, and financing in currencies other than the local currencies in which it operates. The Company enters into various forward contracts, which change in value as foreign currency exchange rates change, to preserve the carrying amount of foreign currency-denominated assets, liabilities, commitments, and certain anticipated foreign currency transactions. Exposures are primarily related to the Canadian Dollar and European Euro exchange rates versus the U.S. dollar. The net fair value of financial instruments used to limit exposure to foreign currency risk was approximately $3 million and break-even as of December 31, 2010 and 2009 respectively. The potential change in fair value at both December 31, 2010 and 2009 for such financial instruments from an increase (decrease) of 10% in quoted foreign currency exchange rates would be an increase (decrease) of approximately $22 million and $11 million, respectively.

Interest Rate Risk

The Company is subject to market risk from exposure to changes in interest rates due to its financing, investing, and cash management activities. The Company has a revolving credit facility, other floating rate debt and cash and cash equivalents which are exposed to floating interest rates and may impact cash flow. As of December 31, 2010, the Company had $12 million outstanding on the senior revolving credit facility and the balance of other floating rate debt was $12 million. As of December 31, 2009, the balance of the senior term loan facility, and other floating rate debt was $600 million, and $29 million, respectively. Cash and cash equivalents were $52 million and $564 million at December 31, 2010 and 2009, respectively. A one percentage point increase (decrease) in interest rates at both December 31, 2010 and 2009 would increase (decrease) our annual net interest expense for each period by $1 million.

The fair market value of the Company’s senior notes are subject to interest rate risk. It is estimated that at December 31, 2010, a one percentage point increase (decrease) in interest rates would (decrease) increase the fair market value of the notes due in 2016 by 5%, the notes due in 2019 by 7% and the notes due in 2036 by 13%. At December 31, 2009, it is estimated that a one percentage point increase (decrease) in interest rates would decrease (increase) the fair market value of the notes due in 2016 by 6%, the notes due in 2019 by 7% and the notes due in 2036 by 13%.

-39-

ITEM 7A.

QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK (continued)

In 2009, the Company entered into fixed to floating interest rate swaps totaling $500 million, designated as a Fair Value hedge of the senior notes due in 2016. A one percentage point increase (decrease) in absolute interest rates would decrease (increase) the fair value of the swaps by $25 million and increase (decrease) annual interest expense by $5 million.

Commodity Price Risk

The Company is exposed to changes in prices of commodities used in its operations, primarily associated with energy, such as natural gas, and raw materials, such as asphalt and polystyrene. The Company enters into cash-settled natural gas and crude oil swap contracts to protect against changes in natural gas prices that mature within 15 months; however, no financial instruments are currently used to protect against changes in raw material costs. At December 31, 2010 and 2009, the net fair value of such swap contracts was a liability of approximately $2 million and $3 million, respectively. The potential change in fair value at December 31, 2010 and 2009 resulting from an increase (decrease) of 10% change in the underlying commodity prices would be an increase (decrease) of approximately $3 million and $3 million, respectively. This amount excludes the offsetting impact of the price risk inherent in the physical purchase of the underlying commodities.

The Company has entered into several energy supply contracts to fix energy costs at certain facilities. Prior to the first quarter of 2009, none of these contracts were required to be accounted for as a derivative because they met the criteria of the normal purchase scope exception. As a result of first quarter 2009 capacity curtailments taken at certain facilities, the normal purchase scope exception is no longer met for one of these supply contracts. As of December 31, 2010, the net fair value of this contract was a liability of $1 million. The potential change in fair value resulting from an increase (decrease) of 10% change in the underlying commodity prices would be an increase (decrease) of approximately $1 million. This amount excludes the offsetting impact of the price risk inherent in the physical purchase of the underlying commodities.

Management’s Report on Internal Control Over Financial Reporting

Management of the Company is responsible for establishing and maintaining adequate internal control over financial reporting as such term is defined in Rules 13a-15(f) and 15d-15(f) under the Securities Exchange Act of 1934.

Report of Independent Registered Public Accounting Firm

To the Board of Directors and Stockholders of Owens Corning:

In our opinion, the accompanying consolidated balance sheets and the related consolidated statements of earnings (loss), stockholders’ equity and cash flows present fairly, in all material respects, the financial position of Owens Corning and its subsidiaries at December 31, 2010 and 2009, and the results of their operations and their cash flows for each of the three years in the period ended December 31, 2010 in conformity with accounting principles generally accepted in the United States of America. In addition, in our opinion, the financial statement schedule listed in the index appearing under Item 15(a)(2) presents fairly, in all material respects, the information set forth therein when read in conjunction with the related consolidated financial statements. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2010, based on criteria established in Internal Control – Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). The Company’s management is responsible for these financial statements and financial statement schedule, for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in Management’s Report on Internal Control Over Financial Reporting. Our responsibility is to express opinions on these financial statements, on the financial statement schedule, and on the Company’s internal control over financial reporting based on our integrated audits. We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the financial statements are free of material misstatement and whether effective internal control over financial reporting was maintained in all material respects. Our audits of the financial statements included examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Description of Business

Owens Corning, a Delaware corporation, is a leading global producer of glass fiber reinforcements and other materials for composite systems and of residential and commercial building materials. The Company operates within two segments: Composites, which includes the Company’s Reinforcements and Downstream businesses; and Building Materials, which includes the Company’s Insulation, Roofing, and Other businesses. Through these lines of business, Owens Corning manufactures and sells products worldwide. The Company maintains leading market positions in all of its major product categories.

Basis of Presentation

Unless the context requires otherwise, the terms “Owens Corning,” “Company,” “we” and “our” in this report refer to Owens Corning and its subsidiaries.

The accompanying Consolidated Financial Statements have been prepared in accordance with accounting principles generally accepted in the United States.

Principles of Consolidation

The Consolidated Financial Statements of the Company include the accounts of majority-owned subsidiaries. Intercompany accounts and transactions are eliminated.

Reclassifications

Certain reclassifications have been made to the 2009 and 2008 Consolidated Financial Statements and Notes to the Consolidated Financial Statements to conform to the classifications used in 2010.

Use of Estimates and Assumptions

The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ materially from those estimates.

Revenue Recognition

Revenue is recognized when title and risk of loss pass to the customer. Provisions for discounts and rebates to customers, returns, warranties and other adjustments are provided in the same period that the related sales are recorded and are based on historical experience, current conditions and contractual obligations, as applicable.

1. BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (continued)

Cost of Sales

Cost of sales includes material, labor, energy and manufacturing overhead costs, including depreciation and amortization expense associated with the manufacture and distribution of the Company’s products. Distribution costs include inbound freight costs; purchasing and receiving costs; inspection costs; warehousing costs; shipping and handling costs, which include costs incurred relating to preparing, packaging, and shipping products to customers; and other costs of the Company’s distribution network. All shipping and handling costs billed to the customer are included as net sales in the Consolidated Statements of Earnings (Loss).

Marketing and Administrative Expenses

Marketing and administrative expenses include selling and administrative costs, including depreciation and amortization expense, not directly associated with the manufacture and distribution of the Company’s products.

Included in marketing and administrative expenses are marketing and advertising costs, which are expensed the first time the advertisement takes place. Marketing and advertising costs include advertising, substantiated customer incentive programs, and marketing communications. Marketing and advertising expenses for the years ended December 31, 2010, 2009 and 2008 were $111 million, $106 million and $131 million, respectively.

Science and Technology Expenses

The Company incurs certain expenses related to science and technology. These expenses include salaries, building and equipment costs, utilities, administrative expenses, materials and supplies associated with the improvement and development of the Company’s products and manufacturing processes. These costs are expensed as incurred.

Earnings (Loss) per Share

Basic earnings (loss) per share are computed using the weighted-average number of common shares outstanding during the period. Diluted earnings (loss) per share reflect the dilutive effect of common equivalent shares and increased shares that would result from the conversion of equity securities. The effects of anti-dilution are not presented.

Cash and Cash Equivalents

The Company defines cash and cash equivalents as cash and time deposits with original maturities of three months or less when purchased.

Accounts Receivable

Trade accounts receivable are recorded at the invoiced amount and do not bear interest. The allowance for doubtful accounts is an estimate of the amount of probable credit losses in our existing accounts receivable. Account balances are charged off against the allowance when the Company believes it is probable the receivable will not be recovered.

As of December 31, 2010 no customer’s balance represented 10% of the Company’s consolidated trade receivables balance. As of December 31, 2009, one customer’s balance represented 12% of the Company’s consolidated trade receivables balance.

Inventory Valuation

Inventory costs include material, labor, and manufacturing overhead costs, including depreciation and amortization expense associated with the manufacture and distribution of the Company’s products. Inventories are stated at lower of cost or market value. Cost is determined by the first-in, first-out (“FIFO”) method.

Investments in Affiliates

The Company accounts for investments in affiliates of 20% to 50% ownership with significant influence using the equity method under which the Company’s share of earnings of the affiliate is reflected in earnings and dividends are credited against the investment in affiliate when declared.

Goodwill and Other Intangible Assets

The Company generally uses the income approach to complete an impairment review unless circumstances indicate that a better estimate of fair value is available. This review is performed annually, or when circumstances arise which indicate there may be an impairment. In applying the income approach, the Company performs a discounted cash flow analysis based on its expectations of future net earnings from each reporting unit. Significant assumptions used include projected cash flows, discount rate, projected income tax rate and terminal business value. These inputs are considered Level 3 inputs under the fair value hierarchy as they are the Company’s own data, and are unobservable in the marketplace. See Note 5 to the Consolidated Financial Statements for further discussion.

Identifiable intangible assets with a determinable useful life are amortized over that determinable life. Amortization expense for the years ended December 31, 2010, 2009 and 2008 was $21 million, $21 million and $22 million, respectively. See Note 5 to the Consolidated Financial Statements for further discussion.

Properties and Depreciation

Property, plant and equipment are stated at cost and depreciated over their estimated useful lives using the straight-line method. Property, plant and equipment accounts are relieved of the cost and related accumulated depreciation when assets are disposed of or otherwise retired. Precious metals used in our production tooling are included in property, plant and equipment and are depleted as they are consumed during the production process. Depletion is recorded in cost of sales on the Consolidated Statements of Earnings (Loss). Precious metals used in our production tooling are depleted as they are consumed during the production process, which typically represents an annual expense of less than 3 percent of the outstanding value. For the years ended December 31, 2010, 2009 and 2008 depreciation expense was $299 million, $304 million and $309 million, respectively.

The range of useful lives for the major components of the Company’s plant and equipment is as follows:


Buildings and leasehold improvements			15 – 40 years
Machinery and equipment
Furnaces			4 – 10 years
Information systems			5 – 10 years
Equipment			5 – 20 years

Expenditures for normal maintenance and repairs are expensed as incurred.

Asset Impairments

The Company exercises judgment in evaluating tangible and intangible long-lived assets for impairment. This requires significant assumptions including projected cash flows, projected income tax rate and terminal business value. These inputs are considered Level 3 inputs under the fair value hierarchy as they are the Company’s own data, and are unobservable in the marketplace. Changes in management intentions, market conditions or operating performance could indicate that impairment charges might be necessary that would be material to the Company’s Consolidated Financial Statements in any given period.

Income Taxes

The Company recognizes current tax liabilities and assets for the estimated taxes payable or refundable on the tax returns for the current year. Deferred tax balances reflect the impact of temporary differences between the carrying amount of assets and liabilities and their tax basis. Amounts are stated at enacted tax rates expected to be in effect when taxes are actually paid or recovered. In addition, realization of certain deferred tax assets is dependent upon our ability to generate future taxable income. The Company records a valuation allowance to reduce its deferred tax assets to the amount that it believes is more likely than not to be realized. In addition, the Company estimates tax reserves to cover potential taxing authority claims for income taxes and interest attributable to audits of open tax years.

Taxes Collected from Customers and Remitted to Government Authorities and Taxes Paid to Vendors

Taxes are assessed by various governmental authorities at different rates on many different types of transactions. The Company charges sales tax or Value Added Tax (“VAT”) on sales to customers where applicable, as well as capture and claim back all available VAT that has been paid on purchases. VAT is recorded in separate payable or receivable accounts and does not affect revenue or cost of sales line items in the income statement. VAT receivable is recorded as a percentage of qualifying purchases at the time the vendor invoice is processed. VAT payable is recorded as a percentage of qualifying sales at the time an Owens Corning sale to a customer subject to VAT occurs. Amounts are paid to the taxing authority according to the method and collection prescribed by local regulations. Where applicable, VAT payable is netted against VAT receivable. The Company also pays sales tax to vendors who include a tax, required by government regulations, to the purchase price charged to the Company.

Pension and Other Postretirement Benefits

Accounting for pensions and other postretirement benefits involves estimating the cost of benefits to be provided well into the future and attributing that cost over the time period each employee works. To accomplish this, extensive use is made of assumptions about investment returns, discount rates, inflation, mortality, turnover and medical costs.

Derivative Financial Instruments

The Company recognizes all derivative instruments as either assets or liabilities at fair value on the balance sheet. To the extent that a derivative is effective as a cash flow hedge, the change in fair value of the derivative is deferred in accumulated other comprehensive deficit (“OCI”). Any portion considered to be ineffective is reported in earnings immediately. To the extent that a derivative is effective as a fair value hedge, the change in the fair value of the derivative is offset by the change in the fair value of the item being hedged in the Consolidated Statements of Earnings (Loss). See Note 4 to the Consolidated Financial Statements for further discussion.

Foreign Currency

The functional currency of the Company’s subsidiaries is generally the applicable local currency. Assets and liabilities of foreign subsidiaries are translated into United States dollars at the period-end rate of exchange, and their Statements of Earnings (Loss) and Statements of Cash Flows are converted on an ongoing basis at the monthly average rate. The resulting translation adjustment is included in accumulated OCI in the Consolidated Balance Sheets and Consolidated Statements of Stockholders’ Equity. Transaction gains and losses that arise from exchange rate fluctuations on transactions denominated in a currency other than the functional currency are included in the Consolidated Statement of Earnings (Loss) as incurred. The Company recorded a foreign currency transaction loss of $8 million, a gain of $8 million and a loss of $1 million during the years ended December 31, 2010, 2009 and 2008, respectively.

2. SEGMENT INFORMATION

The Company has two reportable segments: Composites and Building Materials. Accounting policies for the segments are the same as those for the Company. The Company’s two reportable segments are defined as follows:

Composites – comprised of our Reinforcements and Downstream businesses. Within the Reinforcements business, the Company manufactures, fabricates and sells glass reinforcements in the form of fiber. Within the Downstream business, the Company manufactures and sells glass fiber products in the form of fabrics, mat, veil and other specialized products.

Building Materials – comprised of our Insulation, Roofing, and Other businesses. Within the Insulation business, the Company manufactures and sells fiberglass insulation into residential, commercial, industrial, and other markets for both thermal and acoustical applications. It also manufactures and sells glass fiber pipe insulation, energy efficient flexible duct media and foam insulation used in above- and below-grade construction applications. Insulation also includes construction services, which provides franchise opportunities for the home remodeling and new construction industries as well as Building Materials Europe, which manufactures and sells certain building material products into European markets. Within the Roofing business, the Company manufactures and sells residential roofing shingles and oxidized asphalt materials used in residential and commercial construction and specialty applications. Other includes our United States Masonry Products business (“Masonry Products”), which manufactures and sells stone veneer building products (see Note 9).

4. DERIVATIVE FINANCIAL INSTRUMENTS

The Company is exposed to, among other things, the impact of changes in commodity prices, foreign currency exchange rates, interest rates and precious metals lease rates in the normal course of business. The Company’s risk management program is designed to manage the exposure and volatility arising from these risks, and utilizes derivative financial instruments to offset a portion of these risks. The Company uses derivative financial instruments only to the extent necessary to hedge identified business risks, and does not enter into such transactions for trading purposes.

The Company generally does not require collateral or other security with counterparties to these financial instruments and is therefore subject to credit risk in the event of nonperformance; however, the Company monitors credit risk and currently does not anticipate nonperformance by other parties. Contracts with counterparties generally contain right of offset provisions. These provisions effectively reduce the Company’s exposure to credit risk in situations where the Company has gain and loss positions outstanding with a single counterparty. It is the Company’s policy to offset on the Consolidated Balance Sheets the amounts recognized for derivative instruments with any cash collateral arising from derivative instruments executed with the same counterparty under a master netting agreement. As of December 31, 2010 and 2009, the Company did not have any amounts on deposit with any of its counterparties, nor did any of its counterparties have any amounts on deposit with the Company.

4. DERIVATIVE FINANCIAL INSTRUMENTS (continued)

Assets and liabilities designated as hedged items are assessed for impairment or for the need to recognize an increased obligation. Such assessments are made after hedge accounting has been applied to the asset or liability and exclude consideration of (1) any anticipated effects of hedge accounting and (2) the fair value of any related hedging instrument that is recognized as a separate asset or liability. The assessment for an impairment of an asset, however, includes consideration of the losses that have been deferred in OCI as a result of a cash flow hedge of that asset.

The following table presents the fair value of derivatives and hedging instruments and the respective location on the Consolidated Balance Sheets (in millions):

Cash Flow Hedges

The Company uses forward and swap contracts, which qualify as cash flow hedges, to manage forecasted exposure to natural gas price and foreign exchange risk. The effective portion of the change in the fair value of cash flow hedges is deferred in accumulated OCI on the Consolidated Balance Sheets and is subsequently recognized in other expenses (income) on the Consolidated Statements of Earnings (Loss) for foreign exchange hedges, and in cost of sales on the Consolidated Statements of Earnings (Loss) for commodity hedges, when the hedged item impacts earnings. Cash flow hedges related to foreign exchange risk were immaterial for all periods presented. Changes in the fair value of derivative assets and liabilities designated as hedging instruments are shown in other on the Consolidated Statement of Cash Flows. Any portion of the change in fair value of the derivative designated as hedging instruments that is determined to be ineffective is recorded in other expenses (income) on the Consolidated Statements of Earnings (Loss).

The Company currently has natural gas derivatives designated as hedging instruments that mature within 15 months. The Company’s policy is to hedge up to 75% of its total forecasted natural gas exposures for the next two months, up to 50% of its total forecasted natural gas exposures for the following four months, and lesser amounts for the remaining periods. The Company performs an analysis for effectiveness of its derivatives designated as hedging instruments at the end of each quarter based on the terms of the contract and the underlying item being hedged.

4. DERIVATIVE FINANCIAL INSTRUMENTS (continued)

As of December 31, 2010, $1 million of losses included in OCI on the Consolidated Balance Sheets relate to contracts that will impact earnings during the next 12 months. Transactions and events that are expected to occur over the next 12 months that will necessitate recognizing these deferred losses include the recognition of the hedged item through earnings.

Fair Value Hedges

The Company uses forward currency exchange contracts, which qualify as fair value hedges, to manage existing exposures to foreign exchange risk related to assets and liabilities recorded on the Consolidated Balance Sheets. Gains and losses resulting from the changes in fair value of these instruments are recorded in other expenses (income) on the Consolidated Statements of Earnings (Loss), the effect of which was not material in any period presented. The fair value of these instruments, which are recorded in other current assets on the Consolidated Balance Sheets, was not material for any dates presented.

The Company manages its interest rate exposure by balancing the mixture of its fixed and variable rate instruments. In the fourth quarter of 2009, the Company entered into several interest rate swaps to manage its interest rate exposure by converting $500 million of fixed rate debt to variable rate debt. As such, the swaps are carried at fair value and recorded as other assets or liabilities, with the offset to long-term debt on the Consolidated Balance Sheets. Changes in the fair value of these swaps and that of the related debt are recorded in interest expense, net on the Consolidated Statements of Earnings (Loss).

Other Derivatives

The Company uses forward currency exchange contracts to manage existing exposures to foreign exchange risk related to assets and liabilities recorded on the Consolidated Balance Sheets. Gains and losses resulting from the changes in fair value of these instruments are recorded in other expenses (income) on the Consolidated Statements of Earnings (Loss).

As a result of first quarter 2009 capacity curtailments taken at certain facilities, the normal purchase scope exception was no longer met for one of the Company’s energy supply contracts. The contract is now required to be marked to market each quarter through its termination date of January 31, 2012. Going forward, the impact of this contract could be positive, neutral or negative in any period depending on market fluctuations.

5. GOODWILL AND OTHER INTANGIBLE ASSETS (continued)

Goodwill and Indefinite-Lived Intangible Assets

The Company tests goodwill and indefinite-lived intangible assets for impairment as of October 1^st each year, or more frequently should circumstances change or events occur that would more likely than not reduce the fair value of a reporting unit below its carrying amount. The annual test performed in 2010 resulted in no impairment of goodwill.

In December 2010, management’s strategic outlook on the best use of the Company’s asset portfolio changed. This triggered a requirement to test goodwill and indefinite-lived intangible assets in the Company’s Masonry Products and Building Materials Europe reporting units. The testing resulted in a pre-tax impairment charge of $36 million to goodwill and $60 million to indefinite-lived intangible assets in December 2010. These charges are recorded in other expense (income) on the Consolidated Statements of Earnings (Loss). The fair value for the Masonry Products reporting unit was based upon the Company’s agreement to sell that business. The fair value for Building Materials Europe reporting unit was based upon the Company’s estimates utilizing the discounted cash flow approach. Both the Masonry Products and Building Materials Europe reporting units are part of the Building Materials segment.

6. PROPERTY, PLANT AND EQUIPMENT

Property, plant and equipment consist of the following (in millions):


	Dec. 31, 2010			Dec. 31, 2009

Accumulated depreciation		(1,017	)		(799	)

Property, plant and equipment, net	$	2,754		$	2,806

Machinery and equipment includes certain precious metals used in the Company’s production tooling, which comprise approximately 21% and 23% of total machinery and equipment as of December 31, 2010 and December 31, 2009, respectively. Precious metals used in the Company’s production tooling are depleted as they are consumed during the production process, which typically represents an annual expense of less than 3% of the outstanding carrying value.

In December 2010, management’s strategic outlook on the best use of the Company’s asset portfolio changed. This triggered a requirement to test property, plant and equipment for impairment in the Company’s Masonry Products and Building Materials Europe asset groups. The testing resulted in a pre-tax impairment charge of $21 million related to Masonry Products. This charge is recorded in other expense (income) on the Consolidated Statements of Earnings (Loss). The testing related to Building Materials Europe resulted in no impairment charge. The fair value for the Masonry Products reporting unit was based upon the Company’s agreement to sell that business. The fair value for Building Materials Europe reporting unit was based upon the Company’s estimates utilizing the discounted cash flow approach. Both the Masonry Products and Building Materials Europe asset groups are part of the Building Materials segment.

7. CHANGES IN NONCONTROLLING INTERESTS

In the second quarter of 2009, the Company executed an amended shareholder agreement with the noncontrolling interest of Owens-Corning (India) Limited (“OCIL”), one of the Company’s consolidated subsidiaries. This agreement provided for a put/call provision that became redeemable/exercisable beginning May 31, 2010. Since the exercise of the put option was outside the control of the Company, the carrying value of the noncontrolling interest was recorded as mandatorily redeemable noncontrolling interest on the accompanying consolidated balance sheets.

During 2010, the minority shareholder put their interest in OCIL to the Company for $30 million. The transaction was settled in the fourth quarter of 2010.

The following table discloses the changes in noncontrolling interests on Owens Corning stockholders’ equity and effects on net earnings (loss) attributable to Owens Corning (in millions):
