ITEM 1.			BUSINESS

OVERVIEW

Owens Corning is a global building and construction materials leader committed to building a sustainable future through material innovation. Its fiberglass composites make thousands of products lighter, stronger, and more durable. Its insulation products conserve energy and improve acoustics, fire resistance and air quality in the spaces where people live, work and play. Its roofing products and systems enhance curb appeal of people’s homes and protect homes and commercial buildings alike.

The business is global in scope, with operations in 31 countries, and human in scale, with approximately 19,000 employees and longstanding, local relationships with its customers. Founded in 1938 and based in Toledo, Ohio, Owens Corning recorded net sales in 2022 of $9.8 billion.

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.

SEGMENT OVERVIEW

The Company has an integrated business model with three reportable segments: Composites, Insulation and Roofing. Our Composites, Insulation and Roofing reportable segments accounted for approximately 27%, 37% and 36% of our total reportable segment net sales, respectively, in 2022.

Composites

Owens Corning glass fiber materials can be found in over 40,000 end-use applications primarily within three markets: building and construction, renewable energy and infrastructure. Such end-use applications include building structures, roofing shingles, tubs and showers, pools, decking, flooring, pipes and tanks, poles, electrical equipment and wind-energy turbine blades. 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 segment.

Our Composites segment includes vertically integrated material solutions. The Company manufactures, fabricates and sells glass reinforcements in the form of fiber. Glass reinforcement materials are also used downstream by the Composites segment to manufacture and sell glass fiber products in the form of fabrics, non-wovens 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 compete with glass fiber 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.

Insulation

Our insulating products provide a variety of benefits such as energy conservation, thermal functionality, improved acoustical performance and convenience of installation and use. Our Insulation segment includes a diverse portfolio of high, mid and low-temperature products with a geographic mix of United States, Canada, Europe, Asia-Pacific and Latin America, a market mix of residential, commercial, industrial and other markets, and a channel mix of retail, contractor and distribution.

Our products in the North American residential market include thermal and acoustical batts, loosefill insulation, spray foam, foam sheathing and accessories, and are sold under well-recognized brand names and trademarks such as Owens Corning PINK® FIBERGLAS™ Insulation. Our products in the commercial and industrial markets include glass fiber pipe insulation, energy efficient flexible duct media, bonded and granulated mineral wool insulation, cellular glass insulation and foam insulation used in above- and below-grade construction applications, and are sold under well-recognized brand names and trademarks such as FOAMULAR®, FOAMGLAS® and Paroc®. We sell our insulation products primarily to insulation installers, home centers, lumberyards, retailers and distributors in the United States, Canada, Europe, Asia-Pacific and Latin America.

ITEM 1.			BUSINESS (continued)

Demand for Owens Corning’s insulating products is driven by North American new residential construction, repair and remodeling activity, commercial and industrial construction activity in the United States, Canada, Europe, Asia-Pacific and Latin America, and increasingly stringent building codes and the growing need for energy efficiency. Demand in the segment typically follows seasonal home improvement, remodeling and renovation and residential, commercial and industrial construction industry patterns. Demand for residential insulation in North America typically follows housing starts on a three-month lagged basis, although the new residential construction cycle can elongate due to labor availability and other factors beyond our control. The peak season for home construction and remodeling in our geographic markets generally corresponds with the second and third calendar quarters. Demand for commercial and industrial applications is more heavily tied to industrial production growth, commercial construction activity, and overall economic conditions in the global markets we serve.

Our Insulation segment competes primarily with fiberglass insulation manufacturers in the United States, with an international presence in Canada, Europe, Asia-Pacific and Latin America. According to industry reports and Company estimates, Owens Corning is North America’s largest producer of residential, commercial and industrial insulation. Principal methods of competition include innovation and product design, service, location, quality, price and compatibility of systems solutions.

Working capital practices for this segment historically have followed a seasonal cycle. Typically, our insulation plants run continuously throughout the year. This production plan, along with the seasonal nature of portions of the segment, 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 segment are laminate and strip asphalt roofing shingles. Other products include roofing components, synthetic packaging materials and oxidized asphalt. We have been able to meet the growing demand for longer lasting, aesthetically attractive laminate products with modest capital investment.

We sell shingles and roofing components primarily through distributors, home centers, lumberyards, retailers and contractors in the United States. Our synthetic packaging materials are used primarily in the construction industry for lumber packaging. Oxidized asphalt is a significant input used in the production of our asphalt roofing shingles. We are vertically integrated and have manufacturing facilities that process asphalt for use in our roofing shingles manufacturing process. In addition, we sell processed asphalt to other shingle manufacturers, to roofing contractors for built-up roofing asphalt systems and to manufacturers in a variety of other industries, including automotive, chemical, rubber and construction. Asphalt input costs and third-party asphalt sales prices are correlated to crude oil prices.

Demand for products in our Roofing segment is generally driven by both residential repair and remodeling activity and by new residential construction. Roofing damage from major storms can significantly increase demand in this segment. 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 segment.

Our Roofing segment competes primarily with asphalt shingle manufacturers in the United States. According to various industry reports and Company estimates, Owens Corning’s Roofing segment 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, quality and price.

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 segment 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 a significant interruption of our production in the past, prolonged asphalt shortages would restrict our ability to produce products in this segment.

ITEM 1.			BUSINESS (continued)

GENERAL

Intellectual Property

The Company relies on a combination of intellectual property laws, as well as confidentiality procedures and contractual provisions, to protect our intellectual property, proprietary technology and our brands. Through continuous and extensive use of the color PINK since 1956, Owens Corning became the first owner of a single color trademark registration. In addition to our Owens Corning and PINK brands, the Company has registered, and applied for the registration of, U.S. and international trademarks, service marks, and domain names. Additionally, the Company owns numerous U.S. and international patents and patent applications, covering certain of our proprietary technology resulting from research and development efforts. Over time, the Company has assembled a portfolio of intellectual property rights including patents, trademarks, service marks, copyrights, domain names, know-how and trade secrets covering our products, services and manufacturing processes. Our proprietary technology is not dependent on any single or group of intellectual property rights and the Company does not expect the expiration of existing intellectual property to have a material adverse effect on the business as a whole. The Company believes the duration of our patents is adequate relative to the expected lives of our products. Although the Company protects its intellectual property and proprietary technology, any significant impairment of, or third-party claim against, our intellectual property rights could harm our business or our ability to compete.

Environmental Control

Owens Corning has established policies and procedures to ensure that its operations are conducted in compliance with all relevant laws and regulations and that enable the Company to meet its high standards for corporate sustainability and environmental stewardship. Our manufacturing facilities are subject to numerous foreign, federal, state and local laws and regulations relating to the presence of hazardous materials, pollution and protection of the environment, including emissions to air, discharges to water, management of hazardous materials, handling and disposal of solid wastes, and remediation of contaminated sites. All Company manufacturing facilities are required to use an ISO 14001 or equivalent environmental management system. The Company’s 2030 Sustainability Goals require significant global reductions in energy use, water consumption, waste to landfill, emissions of greenhouse gases, fine particulate matter and volatile organic compound. The Company is dedicated to continuous improvement in our environmental, health and safety performance and to achieving its 2030 Sustainability Goals.

The Company has not experienced a material adverse effect upon its capital expenditures or competitive position as a result of environmental control legislation and regulations. Operating costs associated with environmental compliance were approximately $45 million in 2022. The Company continues 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. It is possible that new laws and regulations will specifically address climate change, volatile organic compounds, ozone forming emissions and fine particulate matter. New environmental and chemical regulations could impact our ability to expand production or construct new facilities in geographic regions in which we operate. 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 current operations, financial condition or long-term liquidity.

Owens Corning is involved in remedial response activities and is responsible for environmental remediation at a number of sites, including certain of its currently owned or formerly owned plants. These responsibilities arise under a number of laws, including, but not limited to, the Federal Resource Conservation and Recovery Act, and similar state or local laws pertaining to the management and remediation of hazardous materials and petroleum. The Company has also been named a potentially responsible party under the United States Federal Superfund law, or state equivalents, at a number of disposal sites. The Company became involved in these sites as a result of government action or in connection with business acquisitions. At the end of 2022, the Company was involved with a total of 23 sites worldwide, including 10 Superfund sites and 13 owned or formerly owned sites. None of the liabilities for these sites are individually significant to the Company.

ITEM 1.			BUSINESS (continued)

Remediation activities generally involve a potential range of activities and costs related to soil and groundwater contamination. This can include pre-cleanup activities such as fact finding and investigation, risk assessment, feasibility studies, remedial action design and implementation (where actions may range from monitoring to removal of contaminants, to installation of longer-term remediation systems). A number of factors affect the cost of environmental remediation, including the number of parties involved in a particular site, the determination of the extent of contamination, the length of time the remediation may require, the complexity of environmental regulations, variability in clean-up standards, the need for legal action, and changes in remediation technology. Taking these factors into account, Owens Corning has predicted the costs of remediation reasonably estimated to be paid over a period of years. The Company accrues an amount on an undiscounted basis, consistent with the reasonable estimates of these costs when it is probable that a liability has been incurred. Actual cost may differ from these estimates for the reasons mentioned above.

At December 31, 2022, the Company had an accrual totaling $5 million for its environmental liabilities, of which the current portion is $1 million. Changes in required remediation procedures or timing of those procedures at existing legacy sites, or discovery of contamination at additional sites, could result in material increases to the Company’s environmental obligations.

Additional Government Laws and Regulations

In addition to environmental laws and regulations, we are subject to various laws and regulations around the world. For example, trade regulations, including tariffs or other import or export restrictions, may increase the cost of some of our raw materials or cross-border shipments, and limit our ability to do business in certain countries or with certain individuals. Our business is also subject to competition laws in the various jurisdictions where we operate, including the Sherman Antitrust Act and related federal and state antitrust laws in the United States, as well as similar foreign laws and regulations. These laws and regulations generally prohibit competitors from fixing prices, boycotting competitors, or engaging in other conduct that unreasonably restrains competition, and such laws and regulations may impact potential business relationships or transactions with third parties in the future. In addition, health and safety regulations have necessitated, and may continue to necessitate, increased operating costs or capital investments to promote a safe working environment. The Company is also required to comply with increasingly complex and changing laws and regulations enacted to protect business and personal data in the United States and other jurisdictions regarding privacy, data protection and data security, including those related to the collection, storage, use, transmission and protection of personal information and other consumer, customer, vendor or employee data. Further, an increasing number of laws and regulations focused on product and chemical hazards, including regulations concerning the impact of product manufacturing and use on climate change, and resulting preferential product selection could also impact our ability to manufacture and sell certain products or require significant research and development investment and capital expenditures to meet regulatory requirements. With respect to the laws and regulations noted above, as well as other applicable laws and regulations, the Company’s compliance programs, may under certain circumstances, involve material investments in the form of additional processes, training, personnel, information technology and capital. For a discussion of the risks associated with certain applicable laws and regulations, see Item 1A, “Risk Factors.”

Sustainability

As a worldwide leader in our industry, we have the desire to be at the forefront of corporate sustainability efforts. It is our ambition to be a net-positive company, that is, one whose positive impact of our people and products, is greater than the negative impact of manufacturing our products. We work to continually increase the good our people and products do while we concurrently reduce the negative environmental impact of our operations.

Our climate-related sustainability efforts have led Owens Corning to develop a range of strategies and tactics that have had a significant impact on the way we conduct our business. We strive to reduce the greenhouse gas emissions released throughout the entire life cycle of our products by improving the use-phase impacts of our products, making our manufacturing processes more energy-efficient, sourcing more renewable electricity, improving our supply chain logistics, increasing recycled content, and developing end-of-life recycling solutions. Together, this work helps to reduce the environmental impact of our operations and lowers the embodied carbon in our products – an attribute of growing importance to our customers.

Many of Owens Corning’s products are made using heavy, industrialized manufacturing processes. While we strive to go beyond all regulatory requirements, our factories do produce various emissions, including greenhouse gases. Owens Corning is subject to or has chosen to voluntarily participate in Emissions Trading Schemes around the world. Broad and gradual tightening of national, regional, and state government limits on emissions could disrupt our access to energy sources or specific raw materials, which in turn could disrupt the manufacturing of products dependent upon them. Owens Corning invests in research and development on climate-related risks and opportunities.

Human Capital Resources

Important to the Company’s long-term success is ensuring its people feel valued, included, and engaged – from recruitment to retirement. That is why Owens Corning is dedicated to fostering an environment of learning and growth within a supportive, caring culture. We are committed to providing a safe, healthy workplace and a meaningful, engaging employee experience.

As of December 31, 2022, Owens Corning had approximately 19,000 employees, of which approximately 10,000 were located outside the United States. Approximately 9,000 (64%) of hourly employees are subject to collective bargaining agreements. The Company believes that its relations with employees are good.

The Company focuses on a number of human capital resource objectives in managing its business which, taken together, may be material to understanding our business under certain circumstances.

Safety and Well-Being

One of our primary objectives is the safety and well-being of our employees. Working safely is an unconditional, organization-wide expectation at Owens Corning, which we believe directly benefits employees’ lives, improves our manufacturing processes and reduces our costs. The Company maintains comprehensive safety programs focused on identifying hazards and eliminating risks that can lead to severe injuries. One of our primary safety measures is the Recordable Incident Rate (“RIR”) as defined by the United States Bureau of Labor Statistics. For the year ended December 31, 2022, our RIR was 0.65, compared to 0.59 as reported in the same period a year ago.

Additionally, with our Healthy Living platform, we provide a multifaceted well-being program designed to drive sustainable, long-term change, improve the health and lives of employees, and strengthen the culture and work experience.

Employee Performance and Related Objectives

We also focus on managing employee performance, development, succession planning, and turnover. Our goal is to create a high-performance culture and teams that are diverse, capable and engaged. We strive to have clear objectives, effective performance management, and a structure that includes regular feedback, talent reviews, succession planning, development, and compensation analysis.

Corporate Culture

Another objective we pursue is maintaining a corporate culture focused on inclusion and diversity, ethics and compliance, training, and positive employee relations and engagement.

The Company believes its success and sustainability are enhanced by an inclusive and diverse workforce. We believe that inclusion and diversity add value to the business by fostering an environment that leads to high engagement and innovative thinking in the workplace. Our Chief Executive Officer, along with more than a thousand other company leaders around the world, signed the CEO Action for Diversity & Inclusion pledge in 2018, signaling our commitment to advance diversity and inclusion within the workplace. Owens Corning operates programs that foster gender and ethnic diversity as well as equality within its workforce, including supporting various employee-led affinity groups, so its employees feel valued and appreciated for the distinct voices they bring to the team.

As of December 31, 2022, the composition of our Board of Directors was 60% demographically diverse, which includes gender, race, ethnicity, nationality, national origin or other elements of one’s identity. Leadership positions were comprised of approximately 29% women globally and 17% people of color in the United States. Our 2030 diversity goals set ambitious targets for Owens Corning leadership positions of 35% women globally and 22% people of color in the United States.

The Company performs a biennial pay equity review with the assistance of a third-party vendor. These reviews include a robust, statistical analysis of pay equity across the majority of its global salaried workforce. Consistent with our commitment to “equal pay for equal work,” we remediate all identified and substantiated pay gaps through pay increases. Further, the Company has implemented processes and policies to avoid inheriting unequal pay bias of prior employers.

Ethics and compliance efforts include our support of the Owens Corning Code of Conduct (“Code of Conduct”), which is dedicated to encouraging compliance with a range of legal guidelines and our corporate values. Our training efforts encompass the Code of Conduct and other areas of compliance and development as relevant to employees. We also seek to foster positive and productive relations with the labor organizations representing them.

ITEM 1A.			RISK FACTORS

In an enterprise as diverse as ours, a wide range of factors could affect future performance. We discuss in this section some of the risk factors that could materially and adversely affect our business, financial condition, value and results of operations. You should consider these risk factors in connection with evaluating the forward-looking statements contained in this Annual Report on Form 10-K because these factors could cause our actual results and financial condition to differ materially from those projected in forward-looking statements.

The Company maintains processes that aim to manage enterprise risks through identification and mitigation of those risks. Despite our efforts, we may fail to identify or mitigate certain risks, which could have a material and adverse impact on our business, financial condition, value and results of operations.

MACROECONOMIC, MARKET AND OPERATIONAL RISKS

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

A large portion of our products are used in the markets for residential and commercial construction and repair and remodeling. Demand for certain of our products is affected in part by the level of new residential construction in the United States and elsewhere, although typically not until a number of months after the change in the level of construction. Lower demand in the regions and markets where our products are sold could result in lower revenues and lower profitability. Historically, construction activity has been cyclical and is influenced by prevailing economic conditions, including the level of interest rates and availability of financing, inflation, employment levels, consumer spending habits, consumer confidence and other macroeconomic factors outside our control. Interest rates and inflation levels rose significantly in 2022, and the reduced affordability of mortgages and other financing options has reduced home sale transaction volumes and new construction activity. We cannot predict if or when interest rates or inflation levels will stabilize or decline or the impact that any such decline may have on repair and remodel activity, new construction activity, demand for our products, our business generally, or our financial condition.

Residential and commercial construction is also affected by the cost and availability of skilled labor, which could impact both the cost and pace of construction activity, as well as the construction methods used, all of which could adversely affect demand for our products.

Some of our products, particularly in our Insulation business, are used in industrial applications, such as piping and storage tanks. Lower levels of industrial production and other macroeconomic factors affecting industrial construction activity could lessen demand for those products and lead to lower revenues or profitability.

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 benefit from the visibility provided by long-term volume contracts against downturns in customer demand and sales. Further, we are not able to immediately adjust our costs in response to declines in sales. In addition, although no single customer represented more than 10% of our annual sales in 2022, our ability to sell some of the products in Insulation and Roofing is dependent on a limited number of customers, who account for a significant portion of such sales. The loss of key customers for these products, a consolidation of key customers or a significant reduction in sales to those customers, could significantly reduce our revenues from these products. In addition, if key customers experience financial pressure or consolidate, 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, loss of key customers and material changes to contractual terms could materially and adversely impact our business, financial condition and results of operations. Furthermore, some of our sales are concentrated in certain geographic areas, and market growth that is skewed to other geographic areas may negatively impact our rate of growth or market share.

Supply constraints and increases in the cost of energy, including because of the ongoing conflict in Ukraine, could have a material adverse impact on our business or results of operations.

Natural gas forms the primary energy source for our European operations, and a significant amount of natural gas in Europe is primarily sourced from Russia. Our European operations can be directly affected by volatility in the cost and availability of energy, which is subject to factors outside of our control. The ongoing conflict between Russia and Ukraine has impacted

Table of Contents

ITEM 1A.			RISK FACTORS (continued)

global energy markets, particularly in Europe, leading to high volatility and increased prices for natural gas and other energy supplies. Reductions in the supply of natural gas from Russia to Europe led to ongoing supply shortages in Europe in 2022. Natural gas supply shortages, or a shutdown of natural gas supply from Russia, could lead to additional price increases, energy supply rationing, or temporary reduction in our European operations, which could have a material adverse impact on our business or results of operations.

We may be exposed to cost increases or reduced availability of raw materials or transportation, which could reduce our margins and have a material adverse impact on our business, financial condition and 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 that are influenced by energy prices, such as asphalt, chemicals, resins, and transportation. 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 occasionally been limited, including because of the COVID-19 pandemic, 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. For example, if one of the raw materials important to our business is sourced from a sole supplier, our production could be interrupted regardless of whether we have a long-term supply contract for the material. Despite our contractual supply agreements with many of our suppliers, and despite any programs we may undertake to mitigate supply risks, it is possible that we could experience a lack of certain raw materials that limits our ability to manufacture our products, thereby materially and adversely impacting our business, financial condition and results of operations.

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

The Company’s business may be materially and adversely impacted by changes in United States or global economic conditions, including global industrial production rates, inflation, deflation, interest rates, availability of capital, consumer spending rates, energy availability and commodity prices, trade laws, and the effects of governmental initiatives to manage economic conditions. Changes in and/or new laws, regulations and policies that may be enacted in the United States or elsewhere could also materially impact economic conditions and the Company's business and results of operations. 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:

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

•one or more of the financial institutions associated with our credit facilities could cease to fulfill their funding obligations, or the amount of eligible receivables under our receivables securitization facility could decrease, which could materially adversely impact our liquidity;

•it may become more expensive 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

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

Furthermore, inflation, which increased significantly in 2022, has and may continue to increase our operational costs and continued increases in interest rates in response to concerns about inflation may further increase economic uncertainty and heighten these risks. If we are unable to increase our prices to offset the effects of inflation, then our business, operating results, and financial condition could be materially and adversely affected.

Uncertainty about global economic conditions may also cause consumers of our products to reduce or 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 may 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.

ITEM 1A.			RISK FACTORS (continued)

We are subject to risks relating to our information technology systems (cybersecurity), and any failure to adequately protect our critical information technology systems could materially affect our operations.

We rely on information technology systems across our operations, including for management, supply chain and financial information and various other processes and transactions. Our ability to effectively manage our business depends on the security, reliability and capacity of these systems. Our information technology systems, some of which are dependent on services provided by third parties, may be vulnerable to damage, interruption, or shutdown due to any number of causes outside of our control such as catastrophic events, natural disasters, fires, power outages, systems failures, telecommunications failures, employee error or malfeasance, security breaches, computer viruses or other malicious codes, ransomware, unauthorized access attempts, denial of service attacks, phishing, hacking, and other cyberattacks. Any such damage, interruption, or shutdown could cause delays or cancellation of customer orders or impede the manufacture or shipment of products, processing of transactions or reporting of financial results. An attack or other problem with our systems could also result in the disclosure of proprietary information about our business or confidential information concerning our customers or employees, which could result in significant damage to our business and our reputation.

We have put in place security measures designed to protect against the misappropriation or corruption of our systems, intentional or unintentional disclosure of confidential information, or disruption of our operations. However, advanced cybersecurity threats, such as malware, ransomware, and phishing attacks, attempts to access information, and other security breaches, are persistent and continue to evolve, making them increasingly difficult to identify and prevent. Protecting against these threats may require significant resources, and we may not be able to implement measures that will protect against all of the significant risks to our information technology systems. In addition, we rely on a number of third-party service providers to execute certain business processes and maintain certain information technology systems and infrastructure, and any breach of security on their part could impair our ability to effectively operate.

Any breach of our security measures could result in unauthorized access to and misappropriation of our information, corruption of data or disruption of operations or transactions, any of which could have a material adverse effect on our business.

Additionally, we regularly move data across national borders to conduct our operations and, consequently, are subject to a variety of laws and regulations in the United States and other jurisdictions regarding privacy, data protection, and data security, including those related to the collection, storage, handling, use, disclosure, transfer, and security of personal data, including the European Union General Data Protection Regulation. Our efforts to comply with privacy and data protection laws may impose significant costs and challenges that are likely to increase over time.

Our efforts in acquiring and integrating other businesses, establishing joint ventures, expanding our production capacity or divesting assets are subject to a number of risks.

Some of the ways we have historically grown or restructured our business have been through acquisitions, joint ventures, the expansion of our production capacity and divestitures. Our ability to grow or restructure our business depends upon our ability to identify, negotiate and finance suitable arrangements. If we cannot successfully execute on such arrangements or receive any required regulatory approvals on a timely basis, we may be unable to generate desired returns, and our expectations of future results of operations, including cost savings and synergies, may not be achieved. Acquisitions, joint ventures, production capacity expansions and divestitures involve substantial risks, including:

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

•increased cybersecurity incidents;

•diversion of financial and management resources from existing operations;

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

•risks relating to obtaining sufficient financing;

•difficulty in integrating the acquired business’ standards, processes, procedures and controls with our existing operations;

•potential loss of key employees;

•unanticipated competitive responses;

•potential loss of customers or suppliers; and

•undisclosed or undiscovered liabilities or claims, or retention of unpredictable future liabilities.

ITEM 1A.			RISK FACTORS (continued)

Our failure to address these risks or other problems encountered in connection with our past or future acquisitions, investments and divestitures could cause us to fail to realize the anticipated benefits of such transactions, 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 have a material adverse impact on our business, financial condition and results of operations. Also, the anticipated benefits of our investments may not materialize.

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 building products and composite products. Some of our competitors may have superior financial, technical, marketing and other resources than we do. 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 pricing, usability, effectiveness, sustainability, quality or other features or benefits. If we are not able to successfully commercialize our innovation 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. In addition, in order to effectively compete, we must continue to develop new products that meet changing consumer preferences and successfully develop, manufacture and market these new products. Our inability to effectively compete could result in the loss of customers and reduce the sales of our products, which could have a material adverse impact on our business, financial condition and results of operations.

Climate change, weather conditions and storm activity could have a material adverse impact on our business, financial condition and results of operations.

Climate change could have an impact on several aspects of our business, financial condition and results of operations. Weather phenomena associated with climate change, such as flooding or altered storm activity, may impact our ability to operate our manufacturing facilities in some locations. In addition, customer preferences for lower-carbon and more environmentally friendly solutions could impact demand for our products. Although we believe that some of our product categories, such as insulation and composites, could experience increased demand due to environmental benefits such as energy efficiency and renewable energy, the timing and impact of such increased demand is uncertain.

Weather conditions and the level of severe storms can have a significant impact on the markets for residential and commercial construction, repair and improvement. These factors could impact our business as follows:

•generally, any weather conditions that slow or limit residential or commercial construction activity can adversely impact demand for our products; and

•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 as a result of either of these weather-related scenarios could have a material adverse impact on our business, financial condition and results of operations. Additionally, severely low temperatures may lead to significant and immediate spikes in costs of natural gas, electricity and other commodities that could negatively affect our results of operation.

We are subject to risks and uncertainties 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:

•difficulties and costs associated with complying with a wide variety of complex and changing laws, including securities laws, tax laws, employment and pension-related laws, competition laws, U.S. and foreign export and trading laws, and laws governing improper business practices, treaties and regulations;

•limitations on our ability to enforce legal rights and remedies;

•adverse domestic or international economic and political conditions, business interruption, war and civil disturbance;

•changes to tax, currency, or other laws or policies that may adversely impact our ability to repatriate cash from non-United States subsidiaries, make cross-border investments, or engage in other intercompany transactions;

•future tax legislation, regulations, or related guidance or interpretations;

Table of Contents

-11-


ITEM 1A.			RISK FACTORS (continued)

•changes to tariffs or other import or export restrictions, penalties or sanctions, including modification or elimination of international agreements covering trade or investment;

•costs and availability of shipping and transportation;

•nationalization or forced relocation of properties by foreign governments;

•currency exchange rate fluctuations between the United States Dollar and foreign currencies; and

•uncertainty with respect to any potential changes to laws, regulations and policies that could exacerbate the risks described above.

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, financial condition and results of operations.

In addition, we operate in many parts of the world that have experienced governmental corruption and we could be adversely affected by violations of the Foreign Corrupt Practices Act (“FCPA”) and similar worldwide anti-corruption laws. The FCPA and similar anti-corruption laws in other jurisdictions generally prohibit companies and their intermediaries from making improper payments to officials for the purpose of obtaining or retaining business. Although we mandate compliance with these anti-corruption laws and maintain an anti-corruption compliance program, these measures may not prevent our employees or agents from violating these laws. If we were found liable for violations of anti-corruption laws, we could be liable for criminal or civil penalties or other sanctions, which could have a material adverse impact on our business, financial condition and results of operations.

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

Many of our business activities globally 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, fires, earthquakes, pandemics or by theft or 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.

LEGAL, REGULATORY AND COMPLIANCE RISKS

We may be subject to liability under and may make substantial future expenditures to comply with environmental and emerging product-based 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. Environmental liability estimates may be affected by changing determinations of what constitutes an environmental exposure or an acceptable level of cleanup. For example, remediation activities generally involve a potential range of activities and costs related to soil and groundwater contamination. This can include pre-cleanup activities such as fact finding and investigation, risk assessment, feasibility studies, remedial action design and implementation (where actions may range from monitoring to removal of contaminants, to installation of longer-term remediation systems). Please see “Item 1 - Business - Environmental Control” for information on costs and accruals related to environmental remediation. To the extent that the required remediation procedures or timing of those procedures change, additional contamination is identified, or the financial condition of other potentially responsible parties is adversely affected, the estimate of our environmental liabilities may change. Change in required remediation procedures or timing of those procedures at existing legacy sites, or discovery of contamination at additional sites, could result in increases to our environmental obligations. 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. It is possible that new laws and regulations will specifically address climate change, toxic air emissions, ozone forming emissions and fine particulate matter. New environmental and chemical regulations could impact our ability to expand production or construct new facilities in every geographic region in which we operate. Continued and increased government and public emphasis on environmental issues is expected to result in increased future investments for environmental controls at ongoing operations,

Table of Contents

-12-


ITEM 1A.			RISK FACTORS (continued)

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. Although emerging in nature, an increasing number of laws and regulations focused on product and chemical hazards, including regulations concerning the impact of product manufacturing and use on climate change, and resulting preferential product selection could also impact our ability to manufacture and sell certain products or require significant research and development investment and capital expenditures to meet regulatory requirements.

Proposed or future laws or regulations aimed at addressing climate change, including, but not limited to, local building codes, Environmental Protection Agency regulations on greenhouse gas emissions, the European Green Deal, laws or regulations impacting energy supply, and other laws or regulations, may materially impact demand for our products or our cost of doing business.

In addition, from time to time, we establish strategies and expectations related to climate change and other environmental matters. Our ability to achieve any such strategies or expectations is subject to numerous factors and conditions, many of which are outside of our control. Examples of such factors include, but are not limited to, evolving regulatory and other standards, processes, and assumptions, the pace of scientific and technological developments, increased costs and availability of requisite financing, market trends that may alter business opportunities, the conduct of third-party manufacturers and suppliers, constraints or disruptions to our supply chain, and changes in carbon markets. Failures or delays (whether actual or perceived) in achieving our strategies or expectations related to climate change and other environmental matters could adversely affect our business, operations, and reputation, and increase risk of litigation. In addition, energy prices could increase as a result of climate change legislation or other environmental mandates, which could have an adverse effect on our results of operations.

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

Our products are used and have been used in a wide variety of residential, commercial and industrial 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. 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 business, financial condition and results of operations.

In addition, consistent with industry practice, we provide warranties on many of our products. We may experience costs of warranty claims when the product is not performing to the satisfaction of the claimant even though it has not caused harm to others or property. 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. Warranty claims are not insurable.

Our intellectual property rights may not provide meaningful commercial protection for our products or brands and third parties may assert that we violate their intellectual property rights, which could have a material adverse impact on our business, financial condition and results of operations.

Owens Corning relies on its intellectual property, including numerous patents, trademarks, trade secrets, confidential information, as well as its licensed intellectual property, to differentiate our products and brands in the marketplace. We monitor and protect against activities that might infringe, dilute, or otherwise harm our intellectual property and rely on the laws of the United States and other countries to protect our rights. However, in some instances, we may be unaware of unauthorized use of our intellectual property. To the extent we cannot protect our innovations or are unable to enforce our intellectual property, unauthorized use and misuse of our intellectual property or innovations 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 foreign jurisdictions provide less protection for our proprietary rights than the laws of the United States and we therefore may not be able to effectively enforce our intellectual property rights in these jurisdictions. If we are unable to maintain certain exclusive licenses, our brand recognition and sales could be adversely impacted. Current employees, contractors and suppliers have, and former employees, contractors and suppliers may have, access to trade secrets and confidential information regarding our operations that could be disclosed improperly and in breach of contract to our competitors or otherwise used to harm us.

Table of Contents

-13-


ITEM 1A.			RISK FACTORS (continued)

Third parties may also claim that we are infringing upon their intellectual property rights. If we are unable to successfully defend or license such alleged infringing intellectual property or if we are required to substitute similar technology from another source, our operations could be adversely affected. Even if we believe that such intellectual property claims are without merit, defending such claims can be costly, time consuming and require significant resources. Claims of intellectual property infringement also may require us to redesign affected products, pay costly damage awards, or face injunctions prohibiting us from manufacturing, importing, marketing or selling certain of our products. Even if we have agreements to indemnify us, indemnifying parties may be unable or unwilling to do so.

We are subject to various legal and regulatory proceedings, including litigation in the ordinary course of business, and uninsured judgments or a rise in insurance premiums may have a material adverse impact on our business, financial condition and results of operations.

In the ordinary course of business, we are subject to various legal and regulatory proceedings, which may include but are not limited to those involving antitrust, tax, trade, environmental, intellectual property, data privacy and other matters, including general commercial litigation. Any claims raised in legal and regulatory proceedings, whether with or without merit, could be time consuming and expensive to defend and could divert management’s attention and resources. Additionally, the outcome of legal and regulatory proceedings may differ from our expectations because the outcomes of these proceedings are often difficult to predict reliably. Various factors and developments can lead to changes in our estimates of liabilities and related insurance receivables, where applicable, or may require us to make additional estimates, including new or modified estimates, that may be appropriate due to a judicial ruling or judgment, a settlement, regulatory developments or changes in applicable law. A future adverse ruling, settlement or unfavorable development could result in charges that could have a material adverse effect on our results of operations in any particular period.

In accordance with customary practice, we maintain insurance against some, but not all, of these potential claims. In the future, we may not be able to maintain insurance at commercially acceptable premium levels. In addition, the levels of insurance we maintain may not be adequate to fully cover any and all losses or liabilities. If any significant judgment or claim is not fully insured or indemnified against, it could have a material adverse impact on our business, financial condition and results of operations.

FINANCIAL RISKS

Our level of indebtedness could adversely impact our business, financial condition or results of operations.

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

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

•a substantial portion of our cash flow 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 available borrowings are at variable rates of interest, exposing us to the risk of increased interest rates to borrow in the future;

•if due to liquidity needs we must replace any indebtedness upon maturity, we would be exposed to the risk that we may not be able to refinance such indebtedness;

•our ability to adjust to changing market conditions may be limited and place us at a competitive disadvantage compared to our competitors if they 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.

The credit agreement governing our senior revolving credit facility, the indentures governing our senior notes, and the receivables purchase agreement governing our receivables securitization facility contain various covenants that impose operating and financial restrictions on us and our subsidiaries. Additionally, instruments and agreements governing our future indebtedness may impose other restrictive conditions or covenants that could restrict our ability to conduct our business operations or pursue growth strategies.

Table of Contents

-14-


ITEM 1A.			RISK FACTORS (continued)

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 and business risk as well as transparency with rating agencies and timeliness of financial reporting. A downgrade in our debt rating could result in increased interest on our existing variable interest rate debt, increased interest and other expenses for future borrowings, and reduced ability for our suppliers to utilize supply chain financing programs. Downgrades in our debt rating could also restrict our access to capital markets and affect the value and marketability of our outstanding notes.

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 applicable laws and regulations, leading to high fixed costs, including depreciation expense. Increased regulatory requirements for our operations could lead to additional or higher fixed 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.

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, new manufacturing platforms, or other capital expenditures, 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, legal 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.

Our results of operations in a given period may be impacted by price volatility in certain renewable-generated energy markets.

In connection with our sustainability goals to reduce greenhouse gas and toxic air emissions, we entered into contracts pursuant to which we have agreed to purchase renewable-generated electricity from third parties. Under these contracts, we do not take physical delivery of renewable-generated electricity. The generated electricity is instead sold by our counterparties to local grid operators at the prevailing market price and we obtain the associated non-tax renewable energy credits. The prevailing market pricing for renewable-generated electricity can be affected by factors beyond our control and is subject to significant period over period volatility. For example, renewable-generated energy output fluctuates due to climactic and other factors beyond our control and can be constrained by available transmission capacity, thereby significantly impacting pricing. Due to this potential volatility, it is possible that these contracts, or similar contracts we execute in the future, could have an impact on our results of operations in a given reporting period.

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.

To mitigate short-term variation in our operating results due to commodity price fluctuations in certain geographic markets, we may hedge a portion of our near-term exposure to the cost of energy. 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, would 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.

If we were required to write down all or part of our goodwill or other indefinite-lived intangible assets, our results of operations or financial condition could be materially adversely affected in a particular period.

Declines in our business may result in an impairment of our tangible and intangible assets, which could result in a material non-cash charge. A significant or prolonged decrease in our market capitalization, including a decline in stock price, a negative

Table of Contents

ITEM 1A.			RISK FACTORS (continued)

long-term performance outlook, or an increase in discount rates could result in an impairment of our tangible and intangible assets which results when the carrying value of the Company’s assets exceed their fair value.

At least annually, we assess our goodwill and intangible assets for impairment. When we utilize a discounted cash flow methodology to calculate the fair value of our reporting units, weak demand for a specific product line or business could result in an impairment. Accordingly, any determination requiring the write-off of a significant portion of goodwill or intangible assets could negatively impact our results of operations.

HUMAN CAPITAL RISKS

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 or the failure to attract additional qualified personnel could adversely impact our business, financial condition and 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. We cannot assure that we will be able to retain all of our existing senior management personnel and skilled and experienced personnel. The loss of any of these individuals or an inability to attract additional qualified personnel could prevent us from implementing our business strategy and could adversely impact our business and our future financial condition or results of operations. The current and future labor markets may impact our ability to retain these individuals.

Labor shortages and increased turnover rates, increases in employee and employee-related costs, and labor disputes could have a material adverse impact on our operations, results of operations, liquidity and cash flows.

Our operations depend on the availability and relative costs of labor and maintaining good relations with our personnel and the labor unions. While we have historically experienced some level of ordinary course turnover of employees, the impact of the COVID-19 pandemic and general economic uncertainty have exacerbated labor shortages and increased turnover. Several factors have had and may continue to have adverse effects on the labor force available to us, including government regulations, laws and regulations related to workers’ health and safety, inflation, wage and hour practices and immigration. Labor shortages and increased turnover rates within our personnel have led to and could in the future lead to increased costs, such as increased costs associated with training new employees and increased wage rates to attract and retain employees. An overall or prolonged labor shortage, lack of skilled labor, increased turnover or labor inflation could have a material adverse impact on our operations, results of operations, liquidity and cash flows.

We are also subject to the risk that labor strikes or other types of conflicts with personnel may arise or that we may become the subject of union organizing activity at additional facilities. Renewal of collective bargaining agreements typically involves negotiation, with the potential for work stoppages or increased costs at affected facilities.

Significant changes in the factors and assumptions used to measure our defined benefit plan obligations, actual investment returns on pension assets and other factors could have a negative impact on our financial condition or liquidity.

We have certain defined benefit pension plans and other post-employment benefit (“OPEB”) plans. Our future funding requirements for defined benefit pension and OPEB plans depend upon a number of factors and assumptions, including our actual experience against assumptions with regard to interest rates used to determine funding levels; return on plan assets; benefit levels; participant experience (e.g., mortality and retirement rates); health care cost trends; and applicable regulatory changes. To the extent actual results are less favorable than our assumptions, there could be a material adverse impact on our financial condition and results of operations.

Additional risks exist due to the nature and magnitude of our investments, including the implementation of or changes to the investment policy, insufficient market capacity to absorb a particular investment strategy or high-volume transactions, and the inability to quickly rebalance illiquid and long-term investments.

If our cash flows and capital resources are insufficient to fund our pension or OPEB obligations, we could be forced to reduce or delay investments and capital expenditures, seek additional capital, or restructure or refinance our indebtedness.

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 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.

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

As a holding company, 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 and receivables facilities and senior notes and the covenants of any future indebtedness we or our subsidiaries may incur.

Provisions in our amended and restated certificate of incorporation and bylaws or Delaware law may discourage, delay or prevent a change in control of the 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 the Company or changes in our management that our stockholders may deem advantageous.

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.

Dividends on our common stock are declared at the discretion of our Board of Directors.

Since February 2014, our Board of Directors has declared a quarterly dividend on our common stock. The payment of any future cash dividends to our stockholders is not guaranteed and 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.

Performance Graph

The annual changes for the five-year period shown in the graph on this page are based on the assumption that $100 had been invested in Owens Corning (OC) stock, the Standard & Poor’s 500 Stock Index (“S&P 500”), the Dow Jones U.S. Construction & Materials Index (“DJ Constr. & Mat.”), and a peer group index on December 31, 2017, and that all quarterly dividends were reinvested. The total cumulative dollar returns shown on the graph represent the value that such investments would have had on December 31, 2022. For December 31, 2022, the Company chose to use a self-selected peer group instead of the Dow Jones U.S. Construction & Materials Index. We have selected this new peer group consisting of the companies noted below because we believe this peer group more appropriately aligns with our specific industry, markets, and global exposure. The criteria used in determining this new peer group included the size of the companies (measured in terms of annual revenue and market capitalization), industries and geographies in which the companies operate, stock price correlation and volatility relative to Owens Corning, and increased representation of comparator companies used by shareholder advisory firms.

ITEM 7.			MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

This Management’s Discussion and Analysis (“MD&A”) is intended to help investors 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,” “its,” and “our” in this report refer to Owens Corning and its subsidiaries.

This section of this Form 10-K generally discusses 2022 and 2021 items and year-to-year comparisons between 2022 and 2021. Discussions of 2020 items and year-to-year comparisons between 2021 and 2020 that are not included in this Form 10-K can be found in “Management's Discussion and Analysis of Financial Condition and Results of Operations” in Part II, Item 7 of the Company's Annual Report on Form 10-K for the fiscal year ended December 31, 2021.

GENERAL

Owens Corning is a global building and construction materials leader committed to building a sustainable future through material innovation. The Company has three reporting segments: Composites, Insulation and Roofing. Through these lines of business, the Company manufactures and sells products worldwide. We maintain leading market positions in many of our major product categories.

EXECUTIVE OVERVIEW

Net earnings attributable to Owens Corning were $1,241 million in 2022, compared to $995 million in 2021. The Company reported $1,723 million in earnings before interest and taxes (“EBIT”) in 2022 compared to $1,448 million in 2021. The Company generated $1,762 million in adjusted earnings before interest and taxes (“Adjusted EBIT”) in 2022 compared to $1,415 million in 2021. See the Adjusted Earnings Before Interest and Taxes paragraph of MD&A for further information regarding EBIT and Adjusted EBIT, including the reconciliation to net earnings (loss) attributable to Owens Corning. Segment EBIT performance compared to 2021 increased $122 million in our Composites segment, increased $166 million in our Insulation segment, and increased $78 million in our Roofing segment. Within our Corporate, Other and Eliminations category, General corporate expenses and other increased by $19 million.

Cash and cash equivalents were $1.1 billion as of December 31, 2022, compared to $959 million as of December 31, 2021, as a result of strong cash flow provided by operating activities. In 2022, the Company's operating activities provided $1,760 million of cash flow, compared to $1,503 million in 2021. The change was primarily driven by higher earnings.

On November 24, 2022, the Company finalized the sale of its Russian operations within the Composites and Insulation segments. As a result of this sale, the Company received $104 million, net of cash sold, in consideration and recorded a pre-tax loss of $33 million in Other expenses (income), net on the Consolidated Statements of Earnings (Loss).

On September 1, 2022, the Company acquired the remaining 50% interest in Fiberteq, LLC (“Fiberteq”), the joint venture between Owens Corning and IKO Industries, Ltd, which produces high-quality wet-formed fiberglass mat for roofing applications for $140 million, net of cash acquired. The acquisition advances the Composites strategy to focus on high-value material solutions and expands Owens Corning's capacity to produce non-woven mat. The Company's 50% interest in Fiberteq was accounted for as an equity-method investment and had a carrying value of $17 million at the acquisition date. The Company used the discounted cash flow method to remeasure the previously held equity method investment to its fair value of $147 million, resulting in the recognition of a gain of $130 million, which is recorded in Gain on equity method investment on the Consolidated Statements of Earnings (Loss). The operating results and a preliminary purchase price allocation for Fiberteq have been included in the Composites segment within the Consolidated Financial Statements since the date of the acquisition. The Company is continuing to obtain information to complete its valuation of certain assets and liabilities. During the year ended December 31, 2022, the Company recorded immaterial measurement period adjustments to the purchase price allocation. The preliminary purchase price allocation included $58 million in intangible assets, which primarily consists of customer relationships with an estimated weighted average life of 3 years, a $62 million unfavorable contract liability and $243 million in goodwill, of which 50% of the goodwill is tax deductible. The factors contributing to the recognition of the amount of goodwill are based on several strategic and synergistic benefits that are expected to be realized from the acquisition. The pro-forma effect of this acquisition on revenues and earnings was not material.

ITEM 7.			MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (continued)

On August 1, 2022, the Company acquired Natural Polymers, LLC (“Natural Polymers”), an innovative manufacturer of spray polyurethane foam insulation for building and construction applications for approximately $111 million, net of cash acquired. The acquisition advances the Owens Corning strategy to strengthen the Company's core building and construction products and expand its addressable markets into higher-growth segments. The operating results and a preliminary purchase price allocation for Natural Polymers have been included in the Insulation segment within the Consolidated Financial Statements since the date of the acquisition. The Company is continuing to obtain information to complete its valuation of certain assets and liabilities. During the year ended December 31, 2022, the Company recorded immaterial measurement period adjustments to the purchase price allocation. The preliminary purchase price allocation included $44 million in intangible assets and $62 million in goodwill, of which all is tax deductible. The intangible assets consist of definite-lived trademarks of $5 million with an estimated weighted average life of 10 years, technology of $12 million with an estimated weighted average life of 6 years and customer relationships of $27 million with an estimated weighted average life of 17 years. The factors contributing to the recognition of the amount of goodwill are based on several strategic and synergistic benefits that are expected to be realized from the acquisition. The pro-forma effect of this acquisition on revenues and earnings was not material.

On July 1, 2022, the Company finalized the sale of the European portion of the dry-use chopped strands (“DUCS”) product line located in Chambéry, France, within the Composites segment. As a result of this sale, the Company received $80 million, net of cash sold, in consideration and recorded a pre-tax loss of $30 million in Other expenses (income), net on the Consolidated Statements of Earnings (Loss).

On June 1, 2022, the Company acquired all of the outstanding assets of WearDeck®, a premium producer of composite weather-resistant decking for commercial and residential applications, for approximately $133 million, net of cash acquired. The acquisition advances the Composites business growth strategy to focus on high-value material solutions within the building and construction industry. The operating results and a preliminary purchase price allocation for WearDeck® have been included in the Composites segment within the Consolidated Financial Statements since the date of the acquisition. The Company is continuing to obtain information to complete its valuation of certain assets and liabilities. During the year ended December 31, 2022, the Company recorded immaterial measurement period adjustments to the purchase price allocation. The preliminary purchase price allocation included $38 million in intangible assets and $68 million in goodwill, of which $61 million is tax deductible. The intangible assets consist of definite-lived trademarks of $7 million with an estimated weighted average life of 10 years, technology of $10 million with an estimated weighted average life of 11 years and customer relationships of $21 million with an estimated weighted average life of 15 years. The factors contributing to the recognition of the amount of goodwill are based on several strategic and synergistic benefits that are expected to be realized from the acquisition. The pro-forma effect of this acquisition on revenues and earnings was not material.

On May 23, 2022, Owens Corning and Pultron Composites (“Pultron”) formed a joint venture (the “JV”) to manufacture and sell fiberglass rebar. The Company contributed approximately $47 million to acquire a 65.5% controlling interest and has established a redeemable noncontrolling interest of $25 million related to Pultron, the minority holder. The JV expands Owens Corning’s capability to produce high-value material solutions by combining the Company’s glass-fiber material technology, channel access and extensive industry experience with Pultron’s manufacturing expertise and process efficiency. The fully consolidated operating results and a preliminary purchase price allocation for the JV have been included in the Company’s Composites segment within the Consolidated Financial Statements since the date of the formation of the JV. Subsequent to the JV formation, the JV acquired assets and technology from Pultron for approximately $65 million. The Company is continuing to obtain information to complete its valuation of certain assets and liabilities. The preliminary purchase price allocation included $15 million in intangible assets, consisting of technology, with an estimated weighted average life of 15 years and $42 million in goodwill, of which $37 million is tax deductible. The factors contributing to the recognition of the amount of goodwill are based on several strategic and synergistic benefits that are expected to be realized from the acquisition. The pro-forma effect of this acquisition on revenues and earnings was not material.

In 2022, the Company repurchased 9.0 million shares of the Company’s common stock for $779 million under a previously announced repurchase authorization. On December 1, 2022, the Company's Board of Directors approved an additional 10 million share repurchase authorization. As of December 31, 2022, 14.4 million shares remained available for repurchase under the announced repurchase authorizations.

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

Net sales increased $1,263 million in 2022 compared to 2021. The increase in net sales was driven by higher selling prices and favorable customer mix which were partially offset by lower sales volumes and the unfavorable impact of translating sales denominated in foreign currencies into United States dollars.

GROSS MARGIN

Gross margin increased $399 million in 2022 compared to 2021. The increase in gross margin was driven by higher selling prices, partially offset by higher input cost inflation and transportation costs in all three segments. The impact of lower sales volumes in Composites and Roofing, as well as unfavorable manufacturing performance in all three segments, further offset the increase from higher selling prices.

MARKETING AND ADMINISTRATIVE EXPENSES

Marketing and administrative expenses increased $46 million in 2022 compared to 2021. The increase was driven primarily by higher general corporate expenses as business activities return to a more typical, post-pandemic level, along with ongoing inflationary pressures.

GAIN ON EQUITY METHOD INVESTMENT

As discussed above, the Company recognized a non-cash gain of $130 million from the remeasurement of the previously held equity method investment in Fiberteq upon the Company’s acquisition of the remaining 50% of the joint venture with IKO.

OTHER EXPENSES (INCOME), NET

Other expenses (income), net increased $192 million in 2022 compared to 2021. The increase in expenses was primarily driven by the unfavorable comparison year-over-year to indefinite-lived intangible asset impairment charges of $96 million and the combined $63 million loss recognized on the sale of the DUCS business in Chambery, France and the sale of our Russian operations in 2022. The remaining increase was driven by $35 million in lower gains on sale of certain precious metals compared to the same period in 2021.

ITEM 7.			MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (continued)

INTEREST EXPENSE, NET

Interest expense, net decreased $17 million in 2022 compared to 2021. The decrease was driven by lower long-term debt balances year-over-year due to the repayment of the senior notes due in 2022 and higher interest income.

LOSS ON EXTINGUISHMENT OF DEBT

During 2022, there were no extinguishments of debt. For the year ended December 31, 2021, the Company recognized a $9 million loss on extinguishment of debt in connection with the repayment of the remaining portion of its outstanding 2022 senior notes.

INCOME TAX EXPENSE

Income tax expense for 2022 was $373 million compared to $319 million in 2021. The Company’s effective tax rate for 2022 was 23% on pre-tax income of $1,614 million. The difference between the 23% effective tax rate and the U.S. federal statutory tax rate of 21% is primarily due to U.S. state and local income tax expense, adjustments to R&D tax credits, and other discrete adjustments.

On August 16, 2022, the U.S. government enacted the Inflation Reduction Act of 2022 (the “Inflation Reduction Act”) into law, which includes a new corporate alternative minimum tax and an excise tax of 1% on the fair market value of net stock repurchases. Both provisions are effective for years after December 31, 2022. The Company is evaluating the potential future impact of the Inflation Reduction Act on its financial position and results of operations.

The realization of deferred tax assets depends on achieving a certain minimum level of future taxable income. Management currently believes that it is at least reasonably possible that the minimum level of taxable income will be met within the next 12 months to reduce the valuation allowances of certain foreign jurisdictions by a range of zero to $3 million.

The Company’s effective tax rate for 2021 was 24% on pre-tax income of $1,313 million. The difference between the 24% effective tax rate and the U.S. federal statutory tax rate of 21% is primarily attributable to U.S. state and local income tax expense, adjustments to foreign tax credits, and other discrete adjustments.

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

Adjusted EBIT is a non-GAAP measure that excludes certain items that management does not allocate to our segment results because it believes they are not representative of the Company’s ongoing operations. 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 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.

NET SALES

Net sales in our Composites segment increased $319 million in 2022 compared to 2021. The increase was driven by higher selling prices of $443 million, partially offset by slightly lower sales volumes of approximately 5%. Favorable customer mix of $61 million was more than offset by the $76 million unfavorable impact of translating sales denominated in foreign currencies into United States dollars. The remaining variance was driven by the net impact of divestitures and acquisitions.

EBIT

EBIT in our Composites segment increased $122 million in 2022 compared to 2021. Higher selling prices of $443 million more than offset $215 million of input cost inflation and $37 million in higher transportation costs. The unfavorable impact of lower sales volumes was nearly offset by the impact of favorable customer mix. The remaining variance was driven by unfavorable manufacturing performance and the $12 million net unfavorable impact of divestitures and acquisitions.

OUTLOOK

Global glass reinforcements market demand is driven by several economic indicators including residential, non-residential construction and manufacturing production indices, as well as global wind installations. The Company is monitoring dynamic market conditions such as an evolving macroeconomic environment, including potential recessionary pressures in the Americas and Europe, input cost inflation, and primary labor availability constraints, which could have an effect on the markets in which we participate. The Company will continue to focus on managing costs, capital expenditures, and working capital.

NET SALES

In our Insulation segment, 2022 net sales increased $530 million compared to 2021. The increase was driven by higher selling prices of $573 million, partially offset by approximately 2% lower sales volumes. Favorable customer and product mix and $29 million from the acquisition of Natural Polymers were mostly offset by the $118 million unfavorable impact of translating sales denominated in foreign currencies into United States dollars.

EBIT

In our Insulation segment, EBIT increased $166 million in 2022 compared to 2021. Higher selling prices of $573 million more than offset $302 million of input cost inflation and $56 million in higher transportation costs. Favorable customer and product mix of $48 million were offset by the impact of unfavorable manufacturing performance and higher production downtime. The remaining variance was driven about equally by higher selling, general and administrative expenses, the impact of lower sales volumes and the negative impact of translating profits denominated in foreign currencies into United States dollars.

OUTLOOK

The outlook for Insulation demand is driven by North American new residential construction, remodeling and repair activity, as well as commercial and industrial construction activity in the United States, Canada, Europe, Asia-Pacific and Latin America. Demand in commercial and industrial insulation markets is most closely correlated to industrial production growth and overall economic activity in the global markets we serve. Demand for residential insulation is most closely correlated to U.S. housing starts.

During the fourth quarter of 2022, the average Seasonally Adjusted Annual Rate (SAAR) of U.S. housing starts was approximately 1.403 million starts, which was down from 1.644 million starts in the fourth quarter of 2021.

The Company expects a deceleration in both the North American new residential construction market and global commercial and industrial construction markets, continued input cost inflation, supply chain uncertainties and primary labor availability constraints. The Company will continue to focus on managing costs, capital expenditures, and working capital.

NET SALES

In our Roofing segment, net sales increased $449 million in 2022 compared to 2021. Higher selling prices of $522 million and higher third-party asphalt sales of $72 million were partially offset by lower sales volumes of approximately 4% and unfavorable customer and product mix.

EBIT

In our Roofing segment, EBIT increased $78 million in 2022 compared to 2021. Higher selling prices of $522 million more than offset input cost inflation, primarily asphalt, of $302 million and $34 million of higher transportation costs. Unfavorable manufacturing performance of $44 million and the impact of lower sales volumes further offset higher selling prices. The remaining variance was driven about equally by higher selling, general and administrative expenses and the impact of unfavorable customer and product mix.

OUTLOOK

In our Roofing segment, the Company expects a deceleration in the North American new residential construction market. Other uncertainties that may impact Roofing demand include demand from storms and other weather-related events, demand from repair and remodeling activity, competitive pricing pressure and the cost and availability of raw materials, particularly asphalt. The Company will continue to focus on managing costs, capital expenditures and working capital.

On August 19, 2021, the Company issued a make-whole call to repay the remaining portion of its outstanding 2022 senior notes, and the redemption was completed in the third quarter of 2021. The Company recognized approximately $9 million of loss on extinguishment of debt in the third quarter of 2021 associated with these actions.

The Company issued $300 million of 2030 senior notes on May 12, 2020. Interest on the notes is payable semiannually in arrears on June 1 and December 1 each year, beginning on December 1, 2020. The proceeds from these notes were used for general corporate purposes.

The Receivables Securitization Facility and Senior Revolving Credit Facility mature in 2024 and 2026, respectively. The Company has no significant debt maturities of senior notes before the fourth quarter of 2024. As of December 31, 2022, the Company had $3.0 billion of total debt and cash and cash equivalents of $1.1 billion. The agreements governing our Senior Revolving Credit Facility and Receivables Securitization Facility contain various covenants that we believe are usual and customary. These covenants include a maximum allowed leverage ratio. We were in compliance with these covenants as of December 31, 2022.

Cash and cash equivalents held by foreign subsidiaries may be subject to foreign withholding taxes upon repatriation to the U.S. As of December 31, 2022 and December 31, 2021, the Company had $188 million and $156 million, respectively, in cash and cash equivalents in certain of its foreign subsidiaries. The Company continues to assert indefinite reinvestment in accordance with Accounting Standards Codification (ASC) 740 based on the laws as of enactment of the tax legislation commonly known as the U.S. Tax Cuts and Jobs Act of 2017.

As a holding company, we have no operations of our own and most of our assets are held by our direct and indirect subsidiaries. Dividends and other payments or distributions from our subsidiaries will be used to meet our debt service and other obligations and to enable us to pay dividends to our stockholders. Please refer to the Risk Factors disclosed in Item 1A of this Form 10-K for details on the factors that could inhibit our subsidiaries' abilities to pay dividends or make other distributions to the parent company.

We have no material off-balance sheet arrangements that have or are reasonably likely to have a material current or future effect on our financial condition, results of operations, liquidity, capital expenditures or other resources.

Material Cash Requirements

Our anticipated uses of cash include capital expenditures, working capital needs, share repurchases, meeting financial obligations, payments of any dividends authorized by our Board of Directors, acquisitions, restructuring actions and pension contributions. 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 and our Receivables Securitization Facility, will provide ample liquidity to enable us to meet our cash requirements.

The following discussion of material cash requirements evaluates known contractual and other obligations, but does not include amounts that are contingent on events or other factors that are uncertain or unknown at this time including legal contingencies, and uncertain tax positions among others. The amounts presented are based on various estimates, including estimates regarding the timing of payments, prevailing interest rates, the occurrence of certain events and other factors. Actual results may vary materially from the amounts discussed below.

Capital Expenditures: Our capital expenditures are primarily related to the maintenance and rebuild of our long-term assets, as well as investing in projects that support growth and innovation to further our enterprise strategy. Our capital expenditures on a cash basis were $446 million in 2022. We expect to have capital expenditures on a cash basis of approximately $520 million in 2023. The anticipated increase in capital expenditures in 2023 is primarily driven by growth and manufacturing productivity projects across all three segments. We expect that capital expenditures will be funded through cash flows from operations. See Note 2 and Note 6 of the Consolidated Financial Statements for additional information on property, plant and equipment.

Long-term debt obligations: As of December 31, 2022, total long-term debt of $3.0 billion primarily consists of various outstanding senior notes with scheduled maturities starting in 2024. Further discussion of the amount and timing of the future scheduled maturities of these senior notes can be found in Note 14 of the Consolidated Financial Statements. There were no borrowings on our Senior Revolving Credit Facility or our Receivables Securitization Facility as of December 31, 2022.

Interest on debt: We are obligated to make periodic interest payments at fixed rates, depending on the terms of the applicable debt agreements. Based on interest rates and scheduled maturities as of December 31, 2022, these interest obligations range from $99 million to $130 million annually over the next five years.

Finance lease obligations: Our finance lease obligations primarily consist of real estate, oxygen plants, computers and software, and fleet vehicles. As of December 31, 2022 we had a total of $157 million of minimum finance lease payments. Further discussion of the future maturities of these lease liabilities can be found in Note 10 of the Consolidated Financial Statements.

Operating lease obligations: Our operating lease obligations primarily consist of real estate and material handling equipment. As of December 31, 2022, we had a total of $227 million of minimum operating lease payments. Further discussion of the future maturities of these lease liabilities can be found in Note 10 of the Consolidated Financial Statements.

Purchase obligations: 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. As of December 31, 2022, the total of these obligations was $384 million, inclusive of $269 million payable in the next 12 months. The Company 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. The Company does not believe such purchase orders will adversely affect our liquidity position.

Pension Contributions: The Company has several defined benefit pension plans. The Company made cash contributions of $8 million and $21 million to the plans during the twelve months ended December 31, 2022 and 2021, respectively. The Company expects to contribute $25 million in cash to its pension plans during 2023. Actual contributions to the plans may change as a result of several 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. Further discussion of the Company's defined benefit pension plans can be found in Note 15 of the Consolidated Financial Statements.

Other Strategic Uses of Cash: We have outstanding share repurchase authorizations and will evaluate and consider repurchasing shares of our common stock, as well as payments of any dividends authorized by our Board of Directors, strategic acquisitions, joint ventures, debt repurchases or repayments and other transactions to create stockholder value and enhance financial performance. Such transactions may require cash expenditures beyond current sources of liquidity or generated proceeds.

Supplier Finance Programs

We review supplier terms and conditions on an ongoing basis, and have negotiated payment terms extensions in recent years in connection with our efforts to reduce working capital and improve cash flow. Separate from those terms extension actions, certain of our subsidiaries have entered into paying agency agreements with third-party administrators. These voluntary supply chain finance programs (collectively, the “Programs”) generally give participating suppliers the ability to sell, or otherwise pledge as collateral, their receivables from the Company to the participating financial institutions, at the sole discretion of both the suppliers and financial institutions. The Company is not a party to the arrangements between the suppliers and the financial institutions. The Company’s obligations to its suppliers, including amounts due and scheduled payment dates, are not impacted by the suppliers’ decisions to sell, or otherwise pledge as collateral, amounts under these arrangements. The Company's payment terms to the financial institutions, including the timing and amount of payments, are based on the original supplier invoices. One of our programs includes a parent guarantee to the participating financial institution for a certain U.S. subsidiary that, at the time of the respective program’s inception in 2015, was a guarantor subsidiary of the Company’s Credit Agreement. The obligations are presented as Accounts payable within Total current liabilities on the Consolidated Balance Sheets and all activity related to the obligations is presented within operating activities on the Consolidated Statements of Cash Flow.

The desire of suppliers and financial institutions to participate in the Programs could be negatively impacted by, among other factors, the availability of capital committed by the participating financial institutions, the cost and availability of our suppliers’ capital, a credit rating downgrade or deteriorating financial performance of the Company or its participating subsidiaries, or other changes in financial markets beyond our control. We do not expect these risks, or potential long-term growth of our programs, to materially affect our overall financial condition, as we expect a significant portion of our payments to continue to be made outside of the Programs. Accordingly, we do not believe the programs have materially impacted our current period liquidity, and do not believe that the programs are reasonably likely to materially affect liquidity in the future.

Please refer to the Supplier Finance Programs section in Note 1 of the Consolidated Financial Statements for a rollforward of outstanding obligations under the supplier finance programs.

Cash Flows

The following table presents a summary of our cash balance, cash flows, and availability on credit facilities (in millions):


	Twelve Months Ended December 31,
	2022		2021		2020
Cash and cash equivalents	$	1,099	$	959	$	717
Net cash flow provided by operating activities	$	1,760	$	1,503	$	1,135
Net cash flow used for investing activities	$	(623)	$	(377)	$	(205)

Availability on the Senior Revolving Credit Facility	$	796	$	796	$	796
Availability on the Receivables Securitization Facility	$	279	$	279	$	279

Cash and cash equivalents: Cash and cash equivalents as of December 31, 2022 increased $140 million compared to December 31, 2021, primarily due to higher cash flow provided by operating activities.

Operating activities: In 2022, the Company generated $1,760 million of cash from operating activities compared to $1,503 million in 2021. The change in cash provided by operating activities was primarily due to higher earnings.

Investing activities: The $246 million increase in cash used for investing activities in 2022 compared to 2021 was primarily driven by higher spending on acquisitions, partially offset by proceeds from divestitures (see Notes 7 and 8 of the Consolidated Financial Statements for further discussion related to our acquisitions and divestitures in 2022).

Financing activities: Net cash used for financing activities in 2022 was $974 million compared to $881 million in 2021. The change year-over-year was primarily due to higher purchases of treasury stock and increased dividends.

Fair Value Measurement

Please refer to Notes 1, 4, 14 and 15 of the Consolidated Financial Statements.

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.

The Company believes 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. The Company has three reporting units: Composites, Insulation and Roofing.

2022 Annual Goodwill Impairment Assessment

Goodwill is an intangible asset that is not subject to amortization; however, annual tests are required to be performed to determine whether impairment exists. Prior to performing the impairment testing process described in ASC 350-20, the guidance permits companies to assess qualitative factors to determine if it is more likely than not that a reporting unit’s fair value is less than its carrying value. If, based on the review of the qualitative factors, we determine it is not more likely than not that the fair value of a reporting unit is less than its carrying value, we would bypass the step one impairment test. Events and circumstances we consider in performing the qualitative assessment include macro-economic conditions, market and industry conditions, internal cost factors, and the operational stability and the overall financial performance of the reporting units. If it is more likely than not that a reporting unit’s fair value is less than or close to its carrying value, then the step one quantitative impairment test must be performed to determine if impairment is required.

-36-


ITEM 7.			MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (continued)

When it is determined necessary for the Company to perform the quantitative impairment process for goodwill, we estimate fair values using a discounted cash flow approach from the perspective of a market participant. Significant assumptions used in the discounted cash flow approach are revenue growth rates and EBIT margins used in estimating discrete period cash flow forecasts of the reporting unit, the discount rate, and the long-term revenue growth rate and EBIT margins used in estimating the terminal business value. The cash flow forecasts of the reporting unit 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 terminal business value is determined by applying the long-term growth rate to the latest year for which a forecast exists. As part of our goodwill quantitative testing process, the Company evaluates whether there are reasonably likely changes to management’s estimates that would have a material impact on the results of the goodwill impairment testing.

Our annual test of goodwill for impairment was conducted as of October 1, 2022. The Company elected to perform the qualitative approach on all of its reporting units: Composites, Insulation and Roofing. After evaluating and weighing all relevant events and circumstances, we concluded that it is not more likely than not that the fair value of the reporting units was less than their carrying amounts. Consequently, we did not perform a step one quantitative analysis for the reporting units and determined goodwill was not impaired for 2022.

The following table summarizes the segment allocation of recorded goodwill on our Consolidated Balance Sheet as of December 31, 2022 (in millions):


Segment	December 31, 2022		Percent of Total
Composites	$	425	31	%
Insulation	564		41	%
Roofing	394		28	%
Total goodwill	$	1,383	100	%

Annual 2022 Indefinite-lived Intangible Asset Impairment Assessment

Fair values used in testing for potential impairment of our trademarks and trade names 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 at a rate based on a market-participant discount rate. Our annual test of indefinite-lived intangibles was conducted as of October 1, 2022.

Based on the results of this testing, the Company recorded pre-tax non-cash impairment charges totaling $96 million in the fourth quarter of 2022. These charges were recorded in Other expenses (income), net on the Consolidated Statements of Earnings (Loss), and were included in the Corporate, Other and Eliminations reporting category.

These charges included the following within the Insulation segment: a pre-tax impairment charge of $63 million for a trade name used by our European building and technical insulation business due to the effect of a higher discount rate, associated with rising interest rates, and general economic and geopolitical uncertainty within the European markets resulting in a slightly lower profitability outlook; a pre-tax impairment charge of $12 million related to a trademark used on global cellular glass insulation products due to the effect of a higher discount rate, associated with rising interest rates, and general economic and geopolitical uncertainty within the European markets; a pre-tax impairment charge of $8 million for a trademark used on mineral wool insulation products sold in the United States due to forecasted profitability of the product line.

The remaining $13 million pre-tax impairment charge for trademarks used within the components business in our Roofing segment was due to the effect of a higher discount rate, associated with rising interest rates, and forecasted profitability of a specific product line.

The fair value of the remaining indefinite-lived intangible assets substantially exceeded the carrying value as of the date of our assessment.

ITEM 7.			MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (continued)

Long-lived Asset Recoverability Assessment

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. The Company groups 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. 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.

However, 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 liabilities and pension expense are the discount rate and the expected return on plan assets. For our largest plan, the United States plan, the discount rate used for the December 31, 2022 measurement date is based on a yield curve approach where the expected future benefit payments are matched with a yield curve derived from certain AA-rated corporate bonds.

The result supported a discount rate of 5.15% at December 31, 2022 compared to 2.85% at December 31, 2021. A 25 basis point increase (decrease) in the discount rate would (decrease) increase the December 31, 2022 projected benefit obligation for the United States pension plan by approximately ($14) and $14 million, respectively. A 25 basis point increase (decrease) in the discount rate would (decrease) increase 2023 net periodic pension cost by less than $1 million.

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 and plan related and investment related expenses paid from the plan trust. The Company uses the target plan asset allocation because we rebalance our portfolio to target on at least 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 5.75% at the December 31, 2022 measurement date, which is used to determine net periodic pension cost for the year 2023. This assumption corresponds to the 4.75% return selected at the December 31, 2021 measurement date. A 25 basis point increase (decrease) in return on plan assets assumption would result in a respective decrease (increase) of 2023 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 5.10% at December 31, 2022 compared to 2.70% at December 31, 2021. A 25 basis point increase (decrease) in the discount rate would (decrease) increase the United States postretirement benefit obligation by approximately $2 million and (decrease) increase 2023 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.

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 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 near-term 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 Notes 1 and 4 to the Consolidated Financial Statements. Please refer to Note 4 for details of the fair values of derivative financial instruments and their classification on the Consolidated Balance Sheets.

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 analysis 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 transactional 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 related to the United States Dollar primarily relative to the Brazilian Real, Chinese Yuan, European Euro, Hong Kong Dollar, Indian Rupee, and South Korean Won exchange rates. Also, there are additional exposures related to the European Euro primarily versus the Polish Złoty and Norwegian Krone. These transactional risks are mitigated through the use of derivative financial instruments and balancing of cash deposits and loans. The net fair value of derivative financial instruments used to limit exposure to foreign currency risk was a liability of $1 million and a liability of $7 million as of December 31, 2022 and 2021, respectively. As of December 31, 2022, the potential change in fair value for such financial instruments from an increase (decrease) of 10% in the quoted foreign currency exchange rates would be a (decrease) increase of approximately $7 million and $5 million, respectively. As of December 31, 2021, the potential change in fair value for such financial instruments from an increase (decrease) of 10% in the quoted foreign currency exchange rates would be a (decrease) increase of approximately $36 million and $36 million, respectively.

We have translation exposure resulting from translating the financial statements of foreign subsidiaries into United States Dollars. Our most significant translation exposures are the Canadian Dollar, Chinese Yuan, European Euro, Indian Rupee, and Polish Złoty in relation to the United States Dollar.

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 Senior Revolving Credit Facility, Receivables Securitization 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, 2022, the Company had no borrowings on its Senior Revolving Credit Facility or Receivables Securitization Facility, with the balance of other floating-rate debt of $1 million. As of December 31, 2021, the Company had no borrowings on its Senior Revolving Credit Facility or Receivables Securitization Facility, with the balance of other floating rate debt of $6 million. Cash and cash equivalents were $1.1 billion and $959 million at December 31, 2022 and 2021, respectively. Based on the year-end outstanding balances on floating rate debt, a one percentage point increase (decrease) in interest rates at December 31, 2022 and 2021 would increase (decrease) our annual net interest expense by less than $1 million for each year.

ITEM 7A.			QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK (continued)

The fair market value of the Company’s senior notes are subject to interest rate risk. The following table shows how a one percentage point increase / decrease in interest rates would impact the fair market value of the senior notes:


	Senior Notes Maturity Year
As of December 31, 2022:	2024	2026	2029	2030	2036	2047	2048
Increase in interest rates
Decrease in fair value	2%	3%	6%	6%	8%	12%	12%
Decrease in interest rates
Increase in fair value	2%	3%	6%	7%	10%	15%	15%

	Senior Notes Maturity Year
As of December 31, 2021:	2024	2026	2029	2030	2036	2047	2048
Increase in interest rates
Decrease in fair value	3%	4%	6%	7%	10%	15%	15%
Decrease in interest rates
Increase in fair value	3%	4%	7%	8%	11%	18%	18%

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 swap contracts in certain markets 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, 2022 and 2021, the net fair value of such swap contracts was a liability of $30 million and an asset of $11 million, respectively. The potential change in fair value at December 31, 2022 and 2021 resulting from an increase (decrease) of 10% in the underlying commodity prices would be an increase (decrease) of $8 million for 2022 and an increase (decrease) of $6 million for 2021. This amount excludes the offsetting impact of the price risk inherent in the physical purchase of the underlying commodities.

Report of Independent Registered Public Accounting Firm

To the Board of Directors and Stockholders of Owens Corning

Opinions on the Financial Statements and Internal Control over Financial Reporting

We have audited the accompanying consolidated balance sheets of Owens Corning and its subsidiaries (the “Company”) as of December 31, 2022 and 2021, and the related consolidated statements of earnings (loss), of comprehensive earnings (loss), of stockholders’ equity and of cash flows for each of the three years in the period ended December 31, 2022, including the related notes and schedule of valuation and qualifying accounts and reserves for each of the three years in the period ended December 31, 2022 appearing on page 109 (collectively referred to as the “consolidated financial statements”). We also have audited the Company's internal control over financial reporting as of December 31, 2022, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of the Company as of December 31, 2022 and 2021, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2022 in conformity with accounting principles generally accepted in the United States of America. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2022, based on criteria established in Internal Control - Integrated Framework (2013) issued by the COSO.

Basis for Opinions

The Company's management is responsible for these consolidated financial statements, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management's Report on Internal Control Over Financial Reporting. Our responsibility is to express opinions on the Company’s consolidated financial statements and on the Company's internal control over financial reporting based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud, and whether effective internal control over financial reporting was maintained in all material respects.

Our audits of the consolidated financial statements included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. 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.

Definition and Limitations of Internal Control over Financial Reporting

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.

Critical Audit Matters

The critical audit matter communicated below is a matter arising from the current period audit of the consolidated financial statements that was communicated or required to be communicated to the audit committee and that (i) relates to accounts or disclosures that are material to the consolidated financial statements and (ii) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.

Indefinite-Lived Intangible Asset Impairment Assessment – Trade Name used by the European Building and Technical Insulation Business

As described in Notes 1 and 5 to the consolidated financial statements, the carrying amount of the Company’s trademarks and tradenames was $1,001 million as of December 31, 2022, a portion of which related to a trade name used by the European building and technical insulation business. Management tests indefinite-lived intangible assets for impairment as of October 1st each year, or more frequently should circumstances change or events occur that would more likely than not reduce the fair value below its carrying amount. Management uses the royalty relief approach to determine whether it is more likely than not that the fair value of these assets is less than the carrying amount. When applying the royalty relief approach, management performs a discounted cash flow analysis based on the value derived from owning the trade name and being relieved from paying royalty to third parties. Significant assumptions used include the discrete period revenue growth rates, long-term EBIT margins, royalty rates, discount rates, and terminal value. In the fourth quarter of 2022, a pre-tax impairment charge of $63 million was recognized related to a trade name used by the European building and technical insulation business.

The principal considerations for our determination that performing procedures relating to the indefinite-lived intangible asset impairment assessment for a trade name used by the European building and technical insulation business is a critical audit matter are (i) the significant judgment by management when developing the fair value estimate of the trade name; (ii) a high degree of auditor judgment, subjectivity and effort in performing procedures and evaluating management’s significant assumptions related to the estimate of long-term EBIT margins and the royalty rate; and (iii) the audit effort involved the use of professionals with specialized skill and knowledge.

Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall opinion on the consolidated financial statements. These procedures included testing the effectiveness of a control relating to management’s indefinite-lived intangible asset impairment assessment for a trade name used by the European building and technical insulation business, including controls over the review of significant assumptions used in the valuation of the trade name. These procedures also included, among others (i) testing management’s process for developing the fair value estimate of the trade name; (ii) evaluating the appropriateness of the royalty relief approach; (iii) testing the completeness and accuracy of underlying data used in the royalty relief approach; and (iv) evaluating the reasonableness of the significant assumptions used by management related to the estimate of long-term EBIT margins and the royalty rate. Evaluating management’s assumptions related to the estimate of long-term EBIT margins and the royalty rate involved evaluating whether the assumptions used by management were reasonable considering (i) the current and past performance of the business associated with the trade name; (ii) the consistency with external market and industry data; and (iii) whether these assumptions were consistent with evidence obtained in other areas of the audit. Professionals with specialized skill and knowledge were used to assist in the evaluation of the reasonableness of the royalty rate.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Description of Business

Owens Corning, a Delaware corporation, is a global building and construction materials leader committed to building a sustainable future through material innovation. The Company operates within three segments: Composites, Insulation and Roofing. Through these lines of business, Owens Corning manufactures and sells products worldwide. The Company maintains leading market positions in many of its major product categories.

General

On February 2, 2023, the Board of Directors declared a quarterly dividend of $0.52 per common share payable on April 6, 2023 to shareholders of record as of March 3, 2023.

Basis of Presentation

Unless the context requires otherwise, the terms “Owens Corning,” “Company,” “we” and “our” in these notes 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 2021 and 2020 Consolidated Financial Statements and Notes to the Consolidated Financial Statements to conform to the classifications used in 2022.

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

We recognize revenue as the amount of consideration that we expect to receive in exchange for transferring promised goods or services to customers. We do not adjust the transaction price for the effects of a significant financing component, as the time period between control transfer of goods and services and expected payment is one year or less. At the time of sale, we estimate provisions for different forms of variable consideration (discounts, rebates, returns and other refund liabilities) based on historical experience, current conditions and contractual obligations, as applicable. The estimated transaction price is typically not subject to significant reversals. We adjust these estimates when the most likely amount of consideration we expect to receive changes, although these changes are typically minor. Sales, value-added and other similar taxes that we collect are excluded from revenue.

Many of our customer volume commitments are short-term and our performance obligations are generally limited to single purchase orders. Substantially all of our revenue is recognized at a point-in-time when control of goods transfers to the customer. Control transfer typically occurs when goods are shipped from our facilities or at other predetermined control transfer points (for instance, destination terms or consignment arrangements).

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued)

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

Revenue Recognition (continued)

We typically do not satisfy performance obligations without obtaining an unconditional right to payment from customers and, therefore, do not carry contract asset balances on the Consolidated Balance Sheets. Contract liability balances are recorded separately from receivables on the Consolidated Balance Sheets in either Total current liabilities or Other liabilities, depending on the timing of performance obligation satisfaction.

We sell separately-priced warranties that extend certain product and workmanship coverages beyond our standard product warranty, which is described in Note 12. The up-front consideration on extended warranty contracts is deferred and recognized as revenue over time, based on the respective coverage period, ranging from 16 to 20 years. On an annual basis, we expect to recognize approximately $6 million of revenue associated with these extended warranty contracts. Additionally, in certain limited cases, we receive consideration before goods or services are transferred to the customer. These customer down payments and deposits are deferred, and typically recognized as revenue in the following quarter when we satisfy the related performance obligations.

As of December 31, 2022, our contract liability balances (for extended warranties, down payments and deposits, collectively) totaled $89 million. As of December 31, 2021, our contract liability balances totaled $76 million, of which $17 million was recognized as revenue throughout 2022. As of December 31, 2020, our contract liability balances (for extended warranties, down payments and deposits, collectively) totaled $66 million, of which $17 million was recognized as revenue throughout 2021. As of December 31, 2019, our contract liability balances (for extended warranties, down payments and deposits, collectively) totaled $60 million, of which $19 million was recognized as revenue throughout 2020.

As a practical expedient, we recognize incremental costs of obtaining a contract, if any, as an expense when incurred if the amortization period of the asset would have been one year or less. We do not have any costs to obtain or fulfill a contract that are capitalized under Accounting Standards Codification (ASC) 606.

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. Provisions for warranties 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. 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. We account for shipping and handling activities that occur after control of the related good transfers as fulfillment activities instead of performance obligations. All shipping and handling costs billed to the customer are included as net sales in the Consolidated Statements of Earnings (Loss).

Marketing and Advertising Expenses

Marketing and advertising expenses are included in Marketing and administrative expenses. These costs include advertising and marketing communications, which are expensed the first time the advertisement takes place. Marketing and advertising expenses for the years ended December 31, 2022, 2021 and 2020 were $125 million, $110 million and $98 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 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.

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

Cash, Cash Equivalents and Restricted Cash

The Company defines cash and cash equivalents as cash and time deposits with maturities of three months or less when purchased. On the Consolidated Statements of Cash Flows, the total of Cash, cash equivalents and restricted cash includes restricted cash of $8 million, $7 million and $7 million as of December 31, 2022, 2021 and 2020, respectively. Restricted cash primarily represents amounts received from a counterparty related to its performance assurance on an executory contract, and is included in Other current assets on the Consolidated Balance Sheets. These amounts are contractually required to be set aside, and the counterparty can exchange the cash for another form of performance assurance at its discretion.

Accounts Receivable

Trade accounts receivable are recorded at the invoiced amount and do not bear interest. Consistent with the requirements of ASU 2016-13, “Financial Instruments - Credit Losses (Topic 236),” the allowance for credit losses is based on the Company’s assessment of the expected losses of customer accounts. The Company regularly reviews the allowance by considering factors such as historical experience, credit quality, the age of the accounts receivable balances, and current economic conditions that may affect a customer’s ability to pay. Account balances are charged off against the allowance when the Company believes it is probable the receivable will not be recovered.

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 net realizable value and expense estimates are made for excess and obsolete inventories. 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 when the Company does not have a controlling financial interest using the equity method under which the Company’s share of earnings and losses of the affiliate is reflected in earnings, and dividends are credited against the investment in affiliate when declared. Investments in affiliates are recorded in Other non-current assets on the Consolidated Balance Sheets, and as of December 31, 2022 and 2021, the total value of investments was $27 million and $45 million, respectively.

Goodwill and Other Intangible Assets

Goodwill assets are not amortized but are tested for impairment on at least an annual basis. The Company has the option to use a qualitative approach to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying value as a basis for determining whether it is necessary to perform a quantitative test. In the current year, as part of the annual assessment, the Company elected to use the qualitative approach for all of its reporting units.

Events and circumstances we consider in performing the qualitative assessment include macro-economic conditions, market and industry conditions, internal cost factors, and the operational stability and the overall financial performance of the reporting units. When it is determined necessary for the Company to perform the quantitative testing process for goodwill, the Company estimates fair values using a discounted cash flow approach from the perspective of a market participant. Significant assumptions used in the discounted cash flow approach are revenue growth rates and earnings before interest and taxes (“EBIT”) margins used in estimating discrete period cash flow forecasts of the reporting unit, the discount rate, and the long-term revenue growth rate and EBIT margins used in estimating the terminal business value. 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 terminal business value is determined by applying the long-term growth rate to the latest year for which a forecast exists. As part of our goodwill quantitative testing process, we would 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.

Goodwill and Other Intangible Assets (continued)

Other indefinite-lived intangible assets are not amortized but are tested for impairment on at least an annual basis or when determined to have a finite useful life. Substantially all of the indefinite-lived intangible assets are in trademarks and trade names. The Company uses the royalty relief approach to determine whether it is more likely than not that the fair value of these assets is less than its carrying amount. This review is performed annually, or when circumstances arise which indicate there may be impairment. When applying the royalty relief approach, the Company performs a discounted cash flow analysis based on the value derived from owning these trademarks and trade names and being relieved from paying royalty to third parties. Significant assumptions used include the discrete period revenue growth rates, long-term EBIT margins, royalty rates, discount rates, and terminal value.

The inputs for the goodwill and indefinite-lived intangible tests are considered Level 3 inputs under the fair value hierarchy as they are the Company’s own data, and are unobservable in the marketplace. Indefinite-lived intangible assets purchased through acquisition are generally tested qualitatively for impairment in the first year following the acquisition before transitioning to the standard methodology described herein in subsequent years.

Please refer to Note 5 for additional disclosures related to Goodwill and Other Intangible Assets.

Emissions Rights

The Company is allotted carbon emission credit allowances (“emissions rights”) from several of the governments under which it operates. These emissions rights are recorded at market value as of the date of issuance and are classified as Intangible assets on the Consolidated Balance Sheets. When the Company emits more than the allotted amounts, additional emissions rights must be purchased.

Properties and Depreciation

Property, plant and equipment are stated at cost and depreciated over their estimated useful lives using the straight-line method. When assets are disposed or otherwise retired, Property, plant and equipment accounts are relieved of the cost and related accumulated depreciation and any gain or loss is included in the Consolidated Statements of Earnings (Loss).

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 typically represents an annual expense of less than 3% of the outstanding value and is recorded in Cost of sales on the Consolidated Statements of Earnings (Loss).

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 – 15 years
Information systems			5 – 10 years
Equipment			5 – 20 years

Expenditures for normal maintenance and repairs are expensed as incurred.

Asset Impairments

The Company evaluates tangible and intangible long-lived assets for impairment when triggering events have occurred. 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 could be material to the Company’s Consolidated Financial Statements in any given period. Please refer to Note 5 for additional detail on impairment charges recorded in 2022 and 2020.

Supplier Finance Programs

The Company's outstanding obligations under the programs for the twelve months ended December 31, 2022 and 2021 are as follows:

Invoices confirmed during the year	656		587
Confirmed invoices paid during the year	(648)		(531)
Confirmed obligations outstanding at the end of the year	$	234	$	226

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. Please refer to Note 21 for additional disclosures related to Income Taxes.

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 captures and claims 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. Please refer to Notes 15 and 16 for additional disclosures related to Pension Plans and Other Postretirement Benefits, respectively.

Derivative Financial Instruments

The Company recognizes all derivative instruments as either assets or liabilities at fair value on the balance sheet. Please refer to Note 4 for further disclosure on derivatives.

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 contracts and the underlying items being hedged. The change in the fair value of cash flow hedges is deferred in Accumulated other comprehensive income (deficit) (“AOCI”) and is subsequently recognized in Cost of sales (for commodity and foreign currency cash flow hedges) on the Consolidated Statements of Earnings (Loss) in order to mirror the location of the hedged items impacting earnings. Cash settlements for commodity and foreign currency hedges qualifying as cash flow hedges are included in Operating activities in the Consolidated Statements of Cash Flows.

The Company has translation exposure resulting from translating the financial statements of foreign subsidiaries into U.S. Dollars, which is recognized in Currency translation adjustment (a component of AOCI). The Company uses cross-currency forward contracts to hedge portions of the net investment in foreign subsidiaries against fluctuations in foreign exchange rates. The changes in fair values of these derivative instruments are recognized in Currency translation adjustment (a component of AOCI), with recognition of the excluded components amortized to Interest expense, net on the Consolidated Statements of Earnings (Loss). Cash settlements for derivatives qualifying as net investment hedges are included in Investing activities in the Consolidated Statements of Cash Flows.

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), net on the Consolidated Statements of Earnings (Loss), and are substantially offset by net revaluation impacts on foreign currency denominated balance sheet exposures (which are also recorded in Other expenses (income), net). Cash settlements for non-designated derivatives are included in the Consolidated Statements of Cash Flows in the category that is consistent with the nature of the derivative instrument, which is generally the same category as the underlying item being hedged.

Fair Value Measurements

The carrying value of cash and cash equivalents, accounts receivable and short-term debt approximate fair value because of the short-term maturity of the instruments.

Please refer to Notes 4, 14 and 15 for fair value disclosures of derivative financial instruments, long-term debt and pension plans.

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 AOCI 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 recorded in Other expenses (income), net in the Consolidated Statements of Earnings (Loss) as incurred. As discussed in the Derivative Financial Instruments section above, the Company uses non-designated foreign currency derivative financial instruments to mitigate this risk. The Company recorded foreign currency transactional (losses)/gains, net of associated derivative activity, of $(4) million, $1 million and $6 million during the years ended December 31, 2022, 2021, and 2020, respectively. Please refer to Note 4 for additional disclosures related to non-designated derivatives.

Related Party Transactions

In the first quarter of 2021, a related party relationship was established as a result of a member of the Company’s Board of Directors being named an executive officer of one of the Company’s preexisting suppliers. The related party transactions with this supplier consist of the purchase of raw materials. Purchases from the related party supplier were $129 million for the year ended December 31, 2022. As of December 31, 2022, amounts due to the related party supplier were $3 million. Purchases from the related party supplier were $87 million for the year ended December 31, 2021. As of December 31, 2021, amounts due to the related party supplier were $1 million.

2. SEGMENT INFORMATION

The Company has three reportable segments: Composites, Insulation and Roofing. Accounting policies for the segments are the same as those for the Company. The Company’s three reportable segments are defined as follows:

Composites – Within our Composites segment, the Company manufactures, fabricates and sells glass reinforcements in the form of fiber. Glass reinforcement materials are also used by the Composites segment to manufacture and sell high value applications in the form of fabrics, non-wovens and other specialized products.

Insulation – Within our Insulation segment, the Company manufactures and sells thermal and acoustical batts, loosefill insulation, spray foam insulation, foam sheathing and accessories. It also manufactures and sells glass fiber pipe insulation, energy efficient flexible duct media, bonded and granulated mineral wool insulation, cellular glass insulation, and foam insulation used in above- and below-grade construction applications.

Roofing – Within our Roofing segment, the Company manufactures and sells residential roofing shingles, oxidized asphalt materials, roofing components used in residential and commercial construction and specialty applications, and synthetic packaging materials.

NET SALES

The following tables show a disaggregation of our net sales by segment and geographic region (in millions). Corporate eliminations (shown below) largely reflect intercompany sales from Composites to Roofing. External customer sales are attributed to geographic region based upon the location from which the product is sold to the external customer.

Our contracts with customers are broadly similar in nature throughout our reportable segments, but the amount, timing and uncertainty of revenue and cash flows may vary in each reportable segment due to geographic and end-market economic factors.

Sales to major customer - No individual customers accounted for 10% or more of consolidated sales in 2022 or 2020. One customer, which is a customer of both the Roofing and Insulation segments, accounted for $895 million (11%) of consolidated sales in 2021.

In the United States, sales are primarily related to the residential housing market and commercial and industrial applications. Residential market demand is driven by housing starts and repair and remodeling activity (influenced by existing home sales, seasonal home improvement and damage from major storms). Significant portions of our residential products across our three reportable segments are used interchangeably in both new construction and repair and remodeling, and our customers typically distribute (or use) the products for both applications. U.S. commercial and industrial revenues are largely driven by U.S. industrial production growth, commercial construction activity and overall economic conditions in the U.S.

Outside of the United States (Europe, Asia-Pacific and Rest of world), sales are primarily related to commercial and industrial applications and, to a lesser extent, residential applications in certain countries. Throughout the international regions, demand is primarily driven by industrial production growth, commercial construction activity and overall economic conditions in each respective geographical region.

4. DERIVATIVE FINANCIAL INSTRUMENTS

The Company is exposed to, among other risks, the impact of changes in commodity prices, foreign currency exchange rates, and interest 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, 2022 and 2021, 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.

Derivative Fair Values

Our derivatives consist of natural gas forward swaps, cross-currency swaps, foreign exchange forward contracts and U.S. treasury rate lock agreements, all of which are over-the-counter and not traded through an exchange. The Company uses widely accepted valuation tools to determine fair value, such as discounting cash flows to calculate a present value for the derivatives. The models use Level 2 inputs, such as forward curves and other commonly quoted observable transactions and prices. The fair value of our derivatives and hedging instruments are all classified as Level 2 investments within the three-tier hierarchy.

Cash Flow Hedges

The Company uses a combination of derivative financial instruments, which qualify as cash flow hedges, and physical contracts to manage forecasted exposure to electricity and natural gas prices. As of December 31, 2022, the notional amounts of these natural gas forward swaps were 8 million MMBTu (or MMBTu equivalent based on U.S. and European indices), compared with the notional amounts of 6 million MMBTu at December 31, 2021.

In March 2020, the Company entered into a $175 million forward U.S. Treasury rate lock agreement to manage the U.S. Treasury portion of its interest rate risk associated with the anticipated issuance of certain 10-year fixed rate senior notes. The Company designated this outstanding forward U.S. Treasury rate lock agreement as a cash flow hedge. The locked fixed rate of this agreement was 0.994%. In September 2022, a gain of $6 million was recognized as a result of a change in the forecasted issuance of certain senior notes. On December 15, 2022, the Company received cash of $37 million upon the settlement of the rate lock agreement, of which $31 million will be amortized as a component of interest expense upon the future issuance of senior notes.

In June 2021, the Company entered into five currency forward contracts with unrelated counterparties with notional amounts totaling $23 million to mitigate against unwanted or anticipated moves in the European Euro exchange rate against the U.S. Dollar, pertaining to forecasted Euro denominated invoices for capital expenditures. The Company has designated each of the individual contracts as cash flow hedges, with the last hedge maturing in December 2022.

Net Investment Hedges

The Company has translation exposure resulting from translating the financial statements of foreign subsidiaries into U.S. Dollars, which is recognized in Currency translation adjustment (a component of AOCI). In the second quarter of 2022, the Company terminated the remaining cross-currency forward contracts related to the hedged portions of the net investment in foreign subsidiaries, resulting in cash proceeds of $11 million.

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. As of December 31, 2022, the Company had notional amounts of $474 million for non-designated derivative financial instruments related to foreign currency exposures in U.S. Dollars primarily related to Brazilian Real, Indian Rupee, Chinese Yuan, European Euro, Hong Kong Dollar, and South Korean Won. In addition, the Company had notional amounts of $111 million for non-designated derivative financial instruments related to foreign currency exposures in European Euro primarily related to the Polish Złoty, Norwegian Krone, and Chinese Yuan.

5. GOODWILL AND OTHER INTANGIBLE ASSETS

The Company tests goodwill and indefinite-lived intangible assets for impairment as of October 1st 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.

Goodwill

The changes in the net carrying amount of goodwill by segment are as follows (in millions):


	Composites		Insulation		Roofing		Total
Gross carrying amount at December 31, 2021	$	75	$	1,481	$	397	$	1,953

Balance, net of impairment at December 31, 2021	$	75	$	518	$	397	$	990

The annual tests performed in the fourth quarter of 2022 and 2021 resulted in no impairment of goodwill.

In the first quarter of 2020, the Company performed its ongoing assessment to consider whether events or circumstances had occurred that could more likely than not reduce the fair value of a reporting unit below its carrying value. The Company’s significant share price reduction during the onset of the COVID-19 pandemic was determined to be an indicator of impairment under ASC 350. The valuation limitation from the Company’s share price decline, the narrow cushion on the Insulation reporting unit and the high level of near-term macroeconomic uncertainty caused the Company to perform an interim goodwill impairment test as of March 31, 2020 over the Insulation reporting unit.

OWENS CORNING AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued)

5. GOODWILL AND OTHER INTANGIBLE ASSETS (continued)

As part of our quantitative testing process for goodwill of the Insulation reporting unit, we estimated fair values using a discounted cash flow analysis, a form of the income approach, from the perspective of a market participant. Significant assumptions used in the discounted cash flow approach are revenue growth rates and EBIT margins used in estimating discrete period cash flow forecasts of the reporting unit, the discount rate, and the long-term revenue growth rate and EBIT margins used in estimating the terminal business value. The terminal business value is determined by applying the long-term growth rate to the latest year for which a forecast exists.

Based on the results of this interim testing over the Insulation reporting unit, the Company recorded a $944 million pre-tax non-cash impairment charge in the first quarter of 2020. This charge was recorded in Goodwill impairment charge on the Consolidated Statements of Earnings (Loss), and was included in the Corporate, Other and Eliminations reporting category. Consistent with the Company’s adoption of ASU 2017-04 in the first quarter of 2020, the impairment charge was equal to the excess of the Insulation reporting unit’s carrying value over its fair value. The reduction in fair value for the Insulation reporting unit, and corresponding impairment charge, was primarily driven by an increase in the discount rate arising from higher equity risk premiums that reflected significant uncertainty surrounding the effect from the COVID-19 pandemic and a decrease in the reporting unit's forecasted near-term cash flows.

Other Intangible Assets

Other intangible assets consist of the following (in millions):


	December 31, 2022						December 31, 2021
	Gross Carrying Amount		Accumulated Amortization		Net Carrying Amount		Gross Carrying Amount		Accumulated Amortization		Net Carrying Amount

Total other intangible assets	$	2,035	$	(433)	$	1,602	$	2,006	$	(389)	$	1,617

(a) Other primarily includes emissions rights.

Indefinite-Lived Intangible Assets

The annual tests performed in the fourth quarter of 2022 resulted in impairment of five of the Company's indefinite-lived intangible assets.

Fair values used in testing for potential impairment of our trademarks are calculated using the relief-from-royalty method 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 at a rate based on a market participant discount rate.

5. GOODWILL AND OTHER INTANGIBLE ASSETS (continued)

The following table presents the remaining carrying values of the impaired trade names and trademarks as of December 31, 2022 (in millions):


Trade names and trademarks	December 31, 2022
European building and technical insulation trade name	$	87
Global cellular glass insulation trademark	$	80
Components branded roofing trademark	$	42
Mineral wool insulation trademark	$	—
Components packaging trademark	$	—

The fair value of the remaining indefinite-lived intangible assets substantially exceeded the carrying value as of the date of our assessment.

The annual test performed in the fourth quarter of 2021 and 2020 resulted in no impairment of indefinite-lived intangible assets.

In the first quarter of 2020, we performed an interim impairment test of one indefinite-lived trademark and one trade name used by our Insulation segment, based on the macroeconomic conditions that precipitated the interim goodwill impairment test described above.

Based on the results of this testing, the Company recorded pre-tax non-cash impairment charges totaling $43 million in the first quarter of 2020 related to one trademark and one trade name in the Insulation segment. These charges were recorded in Other expenses, net on the Consolidated Statements of Earnings (Loss), and were included in the Corporate, Other and Eliminations reporting category.

A pre-tax impairment charge of $34 million for a trade name used by our European building and technical insulation business was recognized in the first quarter of 2020 due to the combined effect of lower expected sales following an immaterial divestiture in the first quarter of 2020, a decrease in the forecasted near-term cash flows, and a higher discount rate associated with the economic impact and uncertainty from the COVID-19 pandemic. A pre-tax impairment charge of $9 million related to a trademark used on global cellular glass insulation products was recorded in the first quarter of 2020 due to a slightly lower sales outlook and a similarly higher discount rate associated with the economic impact and uncertainty from the COVID-19 pandemic.

Definite-Lived Intangible Assets

The Company amortizes the cost of other intangible assets over their estimated useful lives which, individually, range up to 45 years. The Company's future cash flows are not materially impacted by its ability to extend or renew agreements related to its amortizable intangible assets.

Amortization expense for intangible assets for the years ended December 31, 2022, 2021, and 2020 was $55 million, $49 million, and $48 million, respectively. The estimated amortization expense for intangible assets for the next five years is as follows (in millions):

Machinery and equipment includes certain precious metals used in our production tooling, which comprise approximately 10% of total machinery and equipment as of both December 31, 2022 and December 31, 2021.

Our production tooling needs in our Composites segment are changing in response to economic and technological factors. As a result, we exchanged certain precious metals used in production tooling for certain other precious metals to be used in production tooling. These non-cash exchanges resulted in a net increase to Machinery and equipment of $18 million and $41 million and gains totaling $18 million and $41 million for the twelve months ended December 31, 2022 and 2021, respectively. These gains are included in Other expenses (income), net on the Consolidated Statements of Earnings (Loss) and reflected in the Corporate, Other and Eliminations reporting category. These non-cash investing activities are not included in Net cash flow used for investing activities in the Consolidated Statements of Cash Flows. We do not expect these non-cash exchanges to materially impact our current or future capital expenditure requirements or rate of depletion.

For the years ended December 31, 2022, 2021 and 2020, depreciation expense was $447 million, $429 million and $429 million, respectively, which includes depletion expense related to precious metals used in our production tooling. In 2022, 2021 and 2020, depreciation expense included $26 million, $13 million and $20 million, respectively, of accelerated depreciation related to restructuring actions further explained in Note 13 to the Consolidated Financial Statements.

On July 13, 2021, the Company acquired vliepa GmbH (“vliepa”), which specializes in the coating, printing, and finishing of non-wovens, paper, and film for the building materials industry in Europe, for $42 million, net of cash acquired. The acquisition broadens the Company’s global non-wovens portfolio to better serve European customers and accelerate growth of building and construction market applications in the region. The operating results for vliepa have been included in the Company’s Composites segment within the Consolidated Financial Statements since the date of the acquisition. The acquisition resulted in the recognition of $13 million in intangible assets, primarily consisting of customer relationships with an estimated weighted average life of 12 years, and $16 million in goodwill. The pro-forma effect of this acquisition on revenues and earnings was not material.

9. ASSETS HELD FOR SALE

During the third quarter of 2021, the Company entered into a purchase and sale agreement for the Company’s Insulation site in Santa Clara, California to commercial real estate developer Panattoni for expected gross proceeds of approximately $240 million, including a non-refundable deposit of $50 million received at signing. The Company ceased operations in the fourth quarter of 2022, meeting the assets held for sale criteria, and plans to complete the transaction in the first quarter of 2023. This action is part of the Company’s on-going strategy to operate a flexible, cost-efficient manufacturing network and geographically locate its assets to better service its customers. Assets held for sale as of December 31, 2022 were $45 million and primarily consisted of land.

10. LEASES

The Company leases certain equipment and facilities under both operating and finance leases expiring on various dates through 2050. The nature of these leases generally fall into the following five categories: real estate, material handling equipment, fleet vehicles, office equipment and energy equipment.

For leases with initial terms greater than 12 months, we consider these our right-of-use assets and record the related asset and obligation at the present value of lease payments over the term. For leases with initial terms equal to or less than 12 months, we do not consider them as right-of-use assets and instead consider them short-term lease costs that are recognized on a straight-line basis over the lease term.

Many of our leases include escalation clauses, renewal options and/or termination options that are factored into our determination of lease payments when reasonably certain. These options to extend or terminate a lease are at our discretion. We have elected to take the practical expedient and not separate lease and non-lease components of contracts. We estimate our incremental borrowing rate to discount the lease payments based on information available at lease commencement. Our lease agreements do not contain any material residual value guarantees.

13. RESTRUCTURING, ACQUISITION AND DIVESTITURE-RELATED COSTS

The Company may incur restructuring, transaction and integration costs related to acquisitions and divestitures, and may incur restructuring and other exit costs in connection with its global cost reduction, productivity initiatives and the Company's growth strategy.

ACQUISITION AND DIVESTITURE-RELATED COSTS

During 2022, the Company incurred $7 million of transaction costs related to its announced acquisitions and divestitures. Please refer to Note 7 and Note 8 of the Consolidated Financial Statements for further information regarding these actions.

RESTRUCTURING RELATED-COSTS

Composites Strategic Realignment Actions

Throughout 2022, the Company took actions to support our growth strategy in building and construction applications and reduce its cost structure within the Composites segment. These actions include converting the DUCS manufacturing facilities located in Anderson, South Carolina and Kimchon, Korea to produce other glass fiber products and exiting a facility in Japan. The Company recorded costs of $9 million associated with these actions in 2022 and expects to incur an immaterial amount of incremental costs related to these actions in 2023.

Roofing Restructuring Actions

In December 2021, the Company took actions to restructure operations within the Roofing segment's components product line by relocating production assets from China to India to allow the business to optimize its manufacturing network and support a tariff mitigation strategy. During 2022, the Company recorded $3 million of charges primarily related to severance and other exit costs. The Company expects to recognize $2 million of incremental charges related to these actions in 2023.

Santa Clara Insulation Site

During the third quarter of 2021, the Company entered into a purchase and sale agreement for the Company's Insulation site in Santa Clara, California. The Company ceased operations at this facility in the fourth quarter of 2022, meeting the assets held for sale criteria, with plans to complete the transaction in the first quarter of 2023. Please refer to Note 9 of the Consolidated Financial Statements for further information. This action is part of the Company's on-going strategy to operate a flexible, cost-efficient manufacturing network and geographically locate its assets to better service its customers. Cumulative cash pre-tax charges associated with the transaction are expected to be in the range of $30 million to $40 million, primarily related to severance and one-time employee termination benefits, demolition costs, and other closing costs. In addition, cumulative non-cash charges are expected to be in the range of $75 million to $85 million, primarily consisting of accelerated depreciation of property, plant and equipment and derecognition of the carrying value of land, which will offset the gross proceeds at closing.

During 2022, the Company recorded $35 million of charges, comprised of $22 million of accelerated depreciation and $13 million of other exit costs, associated with this agreement.

2020 Insulation Restructuring Actions

During the fourth quarter of 2020, the Company took actions to avoid future capital outlays and reduce costs in its global Insulation segment, mainly through decisions to close certain manufacturing facilities in Shanghai, China and Fresno, Texas, and optimize a facility in Parainen, Finland. During 2022, the Company recorded $2 million of charges primarily related to accelerated depreciation. The Company expects to recognize an immaterial amount of incremental charges related to these actions in 2023.

Acquisition-Related Restructuring

Following the acquisitions of Paroc Group Oy (“Paroc”) and Pittsburgh Corning Corporation and Pittsburgh Corning Europe NV (collectively, “Pittsburgh Corning”) into the Company's Insulation segment, the Company took actions to realize expected synergies from the newly acquired operations. The Company does not expect to recognize significant incremental costs related to these actions.

For the year ended December 31, 2022, the actuarial gain of $277 million was largely the result of increases in discount rates across all plans. In the U.S. plan, the actuarial gain was primarily driven by the increase in the discount rate. The gain was slightly offset by the unfavorable impact of differences between expected and actual pension experience. In the Non-U.S. plans, the actuarial gain was driven by an increase in the discount rate of the U.K. and Canada plans, partially offset by the unfavorable impact of differences between expected and actual pension experience.

For the year ended December 31, 2021, the actuarial gain of $59 million was largely the result of increases in discount rates across all plans. In the U.S. plan, the actuarial gain was primarily driven by the increase in the discount rate. The gain was slightly offset by the unfavorable impact of updated mortality assumptions. In the Non-U.S. plans, the actuarial gain was driven by an increase in the discount rate of the U.K. and other plans, partially offset by inflation.

(a) Not applicable due to changes in plan made on August 1, 2009 that were effective beginning January 1, 2010.

The expected return on plan assets assumption is 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. An asset return model is used to develop an expected range of returns on plan investments over a 30 year period, with the expected rate of return selected from a best estimate range within the total range of projected results. The result is then rounded down to the nearest 25 basis points.

Items Measured at Fair Value

The Company classifies and discloses pension plan assets in one of the following three categories:

Level 1: Quoted market prices in active markets for identical assets.

Level 2: Observable market based inputs or unobservable inputs that are corroborated by market data.

Level 3: Unobservable inputs that are not corroborated by market data.

Plan Assets

The tables in this section show pension plan asset fair values and fair value leveling information. The assets are categorized into one of the three levels of the fair value hierarchy or are not subject to leveling, in the case of investments that are valued using the net asset value per share (or its equivalent) practical expedient (“NAV”).

Investment Strategy

The current targeted asset allocation for the United States pension plan is to have 21.5% of assets invested in equities, 68.5% in intermediate and long-term fixed income securities and 10% in other strategies. Assets are rebalanced at least quarterly to conform to policy tolerances. The Company actively evaluates the reasonableness of its asset mix given changes in the projected benefit obligation and market dynamics. Our investment policy and asset mix for the non-United States pension plans varies by location and is based on projected benefit obligation and market dynamics.

16. POSTEMPLOYMENT AND POSTRETIREMENT BENEFITS OTHER THAN PENSIONS

The Company maintains health care and life insurance benefit plans for certain retired employees and their dependents. The health care plans in the United States are non-funded and pay either (1) stated percentages of covered medically necessary expenses, after subtracting payments by Medicare or other providers and after stated deductibles have been met, or (2) fixed amounts of medical expense reimbursement.

Salaried employees hired on or before December 31, 2005 become eligible to participate in the United States health care plans upon retirement if they have accumulated 10 years of service after age 45, 48 or 50, depending on the category of employee. For employees hired after December 31, 2005, the Company does not provide subsidized retiree health care. Some of the plans are contributory, with some retiree contributions adjusted annually. The Company has reserved the right to change or eliminate these benefit plans subject to the terms of collective bargaining agreements.

The following table provides a reconciliation of the change in the projected benefit obligation and the net amount recognized in the Consolidated Balance Sheets for the years ended December 31, 2022 and 2021 (in millions):

17. CONTINGENT LIABILITIES AND OTHER MATTERS

The Company may be involved in various legal and regulatory proceedings relating to employment, antitrust, tax, product liability, environmental, contracts, intellectual property and other matters (collectively, “Proceedings”). The Company regularly reviews the status of such Proceedings along with legal counsel. Liabilities for such Proceedings are recorded when it is probable that the liability has been incurred and when the amount of the liability can be reasonably estimated. Liabilities are adjusted when additional information becomes available. Management believes that the amount of any reasonably possible losses in excess of any amounts accrued, if any, with respect to such Proceedings or any other known claim, including the matters described below under the caption Environmental Matters (the “Environmental Matters”), are not material to the Company’s financial statements. Management believes that the ultimate disposition of the Proceedings and the Environmental Matters will not have a material adverse effect on the Company’s financial condition. While the likelihood is remote, the disposition of the Proceedings and Environmental Matters could have a material impact on the results of operations, cash flows or liquidity in any given reporting period.

Litigation and Regulatory Proceedings

The Company is involved in litigation and regulatory proceedings from time to time in the regular course of its business. The Company believes that adequate provisions for resolution of all contingencies, claims and pending matters have been made for probable losses that are reasonably estimable.

Environmental Matters

The Company has established policies and procedures designed to ensure that its operations are conducted in compliance with all relevant laws and regulations and that enable the Company to meet its high standards for corporate sustainability and environmental stewardship. Our manufacturing facilities are subject to numerous foreign, federal, state and local laws and regulations relating to the presence of hazardous materials, pollution and protection of the environment, including emissions to air, reductions of greenhouse gases, discharges to water, management of hazardous materials, handling and disposal of solid wastes, use of chemicals in our manufacturing processes, and remediation of contaminated sites. All Company manufacturing facilities are required to use an ISO 14001 or equivalent environmental management system. The Company’s 2030 Sustainability Goals include significant global reductions in energy use, water consumption, waste to landfill, and emissions of greenhouse gases, fine particulate matter, and volatile organic air emissions, and protection of biodiversity.

Owens Corning is involved in remedial response activities and is responsible for environmental remediation at a number of sites, including certain of its currently owned or formerly owned plants. These responsibilities arise under a number of laws, including, but not limited to, the Federal Resource Conservation and Recovery Act, and similar state or local laws pertaining to the management and remediation of hazardous materials and petroleum. The Company has also been named a potentially responsible party under the U.S. Federal Superfund law, or state equivalents, at a number of disposal sites. The Company became involved in these sites as a result of government action or in connection with business acquisitions. As of December 31, 2022, the Company was involved with a total of 23 sites worldwide, including 10 Superfund and state equivalent sites and 13 owned or formerly owned sites. None of the liabilities for these sites are individually significant to the Company.

Remediation activities generally involve a potential range of activities and costs related to soil, groundwater, and sediment contamination. This can include pre-cleanup activities such as fact-finding and investigation, risk assessment, feasibility studies, remedial action design and implementation (where actions may range from monitoring to removal of contaminants, to installation of longer-term remediation systems). A number of factors affect the cost of environmental remediation, including the number of parties involved in a particular site, the determination of the extent of contamination, the length of time the remediation may require, the complexity of environmental regulations, variability in clean-up standards, the need for legal action, and changes in remediation technology. Taking these factors into account, Owens Corning has predicted the costs of remediation reasonably estimated to be paid over a period of years. The Company accrues an amount on an undiscounted basis, consistent with the reasonable estimates of these costs when it is probable that a liability has been incurred. Actual cost may differ from these estimates for the reasons mentioned above. At December 31, 2022, the Company had an accrual totaling $5 million for these costs, of which the current portion is $1 million. Changes in required remediation procedures or timing of those procedures, or discovery of contamination at additional sites, could result in material increases to the Company’s environmental obligations.

18. STOCK COMPENSATION

Description of the Plan

On April 18, 2019, the Company's stockholders approved the Owens Corning 2019 Stock Plan (the “2019 Stock Plan”) which replaced the 2016 Stock Plan. The 2019 Stock Plan authorizes grants of stock options, stock appreciation rights, restricted stock awards, restricted stock units, bonus stock awards, performance stock awards and performance stock units. At December 31, 2022, the number of shares remaining available under the 2019 Stock Plan for all stock awards was 2.6 million.

Prior to 2019, employees were eligible to receive stock awards under the Owens Corning 2016 Stock Plan and the Owens Corning 2013 Stock Plan.

Total Stock-Based Compensation Expense

Stock-based compensation expense included in Marketing and administrative expenses in the accompanying Consolidated Statements of Earnings (Loss) is as follows (in millions):


	Twelve Months Ended December 31,
	2022		2021		2020
Total stock-based compensation expense	$	51	$	50	$	41
Income tax benefit recognized on stock-based compensation expense	$	11	$	14	$	14

Stock Options

The Company has granted stock options under its stockholder approved stock plans. The Company calculates a weighted-average grant-date fair value using a Black-Scholes valuation model for options granted. Compensation expense for options is measured based on the fair market value of the option on the date of grant, and is recognized on a straight-line basis over a four year vesting period. In general, the exercise price of each option awarded was equal to the closing market price of the Company’s common stock on the date of grant and an option’s maximum term is 10 years. The volatility assumption was based on a benchmark study of our peers prior to 2014. Starting with the options granted in 2014, the volatility was based on the Company’s historic volatility.

The Company has not granted stock options since the year ended December 31, 2014. As of December 31, 2022, there was no unrecognized compensation cost related to stock options and the exercise prices on outstanding stock options was $37.65.

The following table summarizes the Company’s stock option activity in 2022:


		Weighted-Average
	Number of Options	Exercise Price		Remaining Contractual Life (in years)	Intrinsic Value (in millions)
Outstanding, December 31, 2021	55,900	$	39.34	1.71	$	3

Exercised	(28,900)	40.93

Restricted Stock Awards and Restricted Stock Units

The Company has granted restricted stock awards and restricted stock units (collectively referred to as “RSUs”) under its stockholder approved stock plans. Compensation expense for restricted stock is measured based on the closing market price of the stock at date of grant and is recognized on a straight-line basis over the vesting period, which is typically three or four years. The Stock Plan allows alternate vesting schedules for death, disability, and retirement.

The weighted average grant date fair value of RSUs granted in 2022, 2021 and 2020 was $90.41, $84.03 and $63.96, respectively.

The following table shows a summary of the Company’s RSU plans:


	Number of RSUs	Weighted- Average Fair Value
Balance at January 1, 2022	1,268,993	$	62.25
Granted	393,834	90.41
Vested	(326,848)	65.87
Forfeited	(59,819)	75.41
Balance at December 31, 2022	1,276,160	$	69.16

As of December 31, 2022, there was $33 million of total unrecognized compensation cost related to RSUs. That cost is expected to be recognized over a weighted-average period of 2.36 years. The total grant date fair value of shares vested during the years ended December 31, 2022, 2021 and 2020 was $22 million, $26 million and $27 million, respectively.

Performance Stock Awards and Performance Stock Units

The Company has granted performance stock awards and performance stock units (collectively referred to as “PSUs”) as a part of its long-term incentive plan. All outstanding performance grants will fully settle in stock. The amount of stock ultimately distributed from the 2022, 2021 and 2020 grants is contingent on meeting internal company-based metrics or an external-based stock performance metric.

In 2022, 2021 and 2020, the Company granted both internal company-based and external-based metric PSUs.

Internal Company-based metrics

The internal company-based metrics vest after a three-year period and are based on various company-based metrics over a three-year period. The amount of stock distributed will vary from 0% to 300% of PSUs awarded depending on performance versus the company-based metrics.

The initial fair value for all internal company-based metric PSUs assumes that the performance goals will be achieved and is based on the grant date stock price. This assumption is monitored quarterly and if it becomes probable that such goals will not be achieved or will be exceeded, compensation expense recognized will be adjusted and previous surplus compensation expense recognized will be reversed or additional expense will be recognized. The expected term represents the period from the grant date to the end of the three-year performance period. Pro-rata vesting may be utilized in the case of death, disability or retirement, and awards, if earned, will be paid at the end of the three-year period.

External based metrics

The external-based metrics vest after a three-year period. Outstanding grants issued in or after 2018 were based on the Company's total stockholder return relative to the performance of the Dow Jones U.S. Construction & Materials Index. The amount of stock distributed will vary from 0% to 200% of PSUs awarded depending on the relative stockholder return performance. The fair value of external-based metric PSUs has been estimated at the grant date using a Monte Carlo simulation that uses various assumptions.

Employee Stock Purchase Plan

The Owens Corning Employee Stock Purchase Plan (ESPP) is a tax qualified plan under Section 423 of the Internal Revenue Code. The purchase price of shares purchased under the ESPP is equal to 85% of the lower of the fair market value of shares of Owens Corning common stock at the beginning or ending of the offering period, which is a six month period ending on May 31 and November 30 of each year. On April 16, 2020, the Company's stockholders approved the Amended and Restated Owens Corning Employee Stock Purchase Plan which increased the number of shares available for issuance under the plan by 4.2 million shares. As of December 31, 2022, 3.5 million shares remain available for purchase.

Included in total stock-based compensation expense is $6 million, $6 million and $6 million of expense related to the Company's ESPP for the years ended December 31, 2022, 2021 and 2020, respectively. As of December 31, 2022, the Company had $3 million of total unrecognized compensation costs related to the ESPP. Under the outstanding ESPP as of February 14, 2023, employees have contributed $5 million to purchase shares for the current purchase period ending May 31, 2023.

Basic	$	12.85	$	9.61	$	(3.53)
Diluted	$	12.70	$	9.54	$	(3.53)

Basic earnings (loss) per share is calculated by dividing earnings (loss) attributable to Owens Corning by the weighted-average number of shares of the Company’s common stock outstanding during the period. Outstanding shares consist of issued shares less treasury stock.

On February 14, 2022, the Board of Directors approved a share buy-back program under which the Company is authorized to repurchase up to 10 million shares of the Company’s outstanding common stock (the “February 2022 Repurchase Authorization”). The February 2022 Repurchase Authorization is in addition to the 2020 Repurchase Authorization (the 2020 Repurchase Authorization and collectively with the 2022 Repurchase Authorization, the “Repurchase Authorization”). The Company repurchased 9.0 million shares of its common stock for $779 million during the year ended December 31, 2022 under the Repurchase Authorization.

On December 1, 2022, the Board of Directors approved a new share buy-back program under which the Company is authorized to repurchase up to 10 million shares of the Company’s outstanding common stock (the “December 2022 Repurchase Authorization”). The December 2022 Repurchase Authorization is in addition to the February 2022 Repurchase Authorization (together, the “Repurchase Authorization”). The Repurchase Authorization enables the Company to repurchase shares through the open market, privately negotiated, or other transactions. The actual number of shares repurchased will depend on timing, market conditions and other factors and will be at the Company's discretion. As of December 31, 2022, 14.4 million shares remained available for repurchase under the Repurchase Authorization.

For the year ended December 31, 2022, the Company did not have any non-vested restricted shares or non-vested performance shares that had an anti-dilutive effect on earnings per share. For the year ended December 31, 2021, the number of shares used in the calculation of diluted earnings per share did not include 0.1 million non-vested performance shares due to their anti-dilutive effect. For the year ended December 31, 2020, diluted earnings per share was equal to basic earnings per share due to the net loss attributable to Owens Corning.

In addition, non-cash charges were recorded in 2020 related to valuation allowance adjustments against certain deferred tax assets recorded in our French, Indian and Other foreign legal entities due to volatility in the markets we serve from the COVID-19 pandemic.

In December 2020, the company completed an intercompany restructuring that resulted in the transfer of certain intellectual property rights, held by wholly owned foreign subsidiaries, to the U.S. The intellectual property rights transferred to the U.S. resulted in a step-up in the tax basis for U.S. tax purposes which resulted in the company recognizing a deferred tax asset of $37 million and tax expense of $5 million. The recognized tax benefit of $37 million is amortizable for U.S. tax purposes over a fifteen-year period.

On July 20, 2020 the Internal Revenue Service (IRS) issued final regulations under IRC Section 951A permitting a taxpayer to elect to exclude, from its inclusion of global intangible low-taxed income (GILTI), income subject to a high foreign effective tax rate. As a result of the final regulations, the company recorded a net non-cash income tax benefit of $13 million in the third quarter of 2020 relating to the 2018 and 2019 tax years.

The Company continues to assert indefinite reinvestment in accordance with ASC 740 based on the laws as of enactment of the Tax Act. As of December 31, 2022, the Company has not provided for withholding or income taxes on approximately $1.8 billion of undistributed reserves of its foreign subsidiaries and affiliates as they are considered by management to be permanently reinvested. Quantification of the deferred tax liability associated with these undistributed reserves is not practicable.

The cumulative temporary differences giving rise to the deferred tax assets and liabilities are as follows (in millions):


	December 31, 2022				December 31, 2021
	Deferred Tax Assets		Deferred Tax Liabilities		Deferred Tax Assets		Deferred Tax Liabilities

The following table summarizes the amount and expiration dates of our deferred tax assets related to operating loss and tax credit carryforwards and foreign tax credit carryforwards at December 31, 2022 (in millions) (a):

(a)The use of certain of the Company's losses and credits is limited pursuant to sections 382 and 383 of the Internal Revenue Code which 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 more than 50% in the ownership positions of certain stockholders during a rolling three-year period. The Company believes that these limitations will not result in a forfeiture of the carryforwards.

(b)The foreign net operating losses are related to various jurisdictions that provide for both indefinite carryforward periods and others with carryforward periods that range from the tax years 2023 to 2036.

Deferred income taxes are provided for temporary differences between amounts of assets and liabilities for financial reporting purposes and the basis of such assets and liabilities as measured under enacted tax laws and regulations, as well as NOLs, tax credits and other carryforwards. A valuation allowance will be recorded to reduce deferred tax assets if, based on all available evidence, it is considered more likely than not that some portion or all of the recorded deferred tax assets will not be realized in future periods. To the extent the reversal of deferred tax liabilities is relied upon in our assessment of the realizability of deferred tax assets, they will reverse in the same period and jurisdiction as the temporary differences giving rise to the deferred tax assets. As of December 31, 2022, the Company had net deferred tax liabilities before valuation allowances of $243 million.

The valuation allowance of $129 million as of December 31, 2022 is related to U.S. federal foreign tax credits (FTCs) and certain state and foreign jurisdictions. The realization of deferred tax assets depends on achieving a certain minimum level of future taxable income. Management currently believes that it is at least reasonably possible that the minimum level of taxable income will be met within the next 12 months to reduce the valuation allowance of certain foreign jurisdictions by a range of zero to $3 million. The valuation allowance of $132 million as of December 31, 2021 is related to U.S. federal FTC's and certain state and foreign jurisdictions.

The Company, or one of its subsidiaries, files income tax returns in the United States and other foreign jurisdictions. The Company is no longer subject to U.S. federal tax examinations for years before 2019 or state and foreign examinations for years before 2016. Due to the potential for resolution of federal, state and foreign examinations, and the expiration of various statutes of limitation, it is reasonably possible that the gross unrecognized tax benefits balance may change within the next 12 months by a range of zero to $5 million.

A reconciliation of the beginning and ending amounts of unrecognized tax benefits is as follows (in millions):


	Twelve Months Ended December 31,
	2022		2021		2020
Balance at beginning of period	$	74	$	76	$	79
Tax positions related to the current year
Gross additions	—		—		—
Tax positions related to prior years
Gross additions	2		1		2
Gross reductions	—		(1)		(1)
Settlements	(1)		(1)		(1)
Expiration of statute of limitations	(3)		(1)		(3)
Impact of currency changes	(1)		—		—
Balance at end of period	$	71	$	74	$	76

If these unrecognized tax benefits were to be recognized as of December 31, 2022, the Company’s income tax expense would decrease by about $52 million.

The Company classifies all interest and penalties as income tax expense. As of December 31, 2022, 2021 and 2020, and for the periods then ended, the Company recognized $7 million, $7 million and $7 million, respectively, in liabilities for tax related interest and penalties on its Consolidated Balance Sheets and $1 million, $2 million and less than $1 million, respectively, of interest and penalty expense on its Consolidated Statements of Earnings (Loss).

Accounting Policies [Abstract]

BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIESDescription of Business
Owens Corning, a Delaware corporation, is a global building and construction materials leader committed to building a sustainable future through material innovation. The Company operates within three segments: Composites, Insulation and Roofing. Through these lines of business, Owens Corning manufactures and sells products worldwide. The Company maintains leading market positions in many of its major product categories.

General

On February 2, 2023, the Board of Directors declared a quarterly dividend of $0.52 per common share payable on April 6, 2023 to shareholders of record as of March 3, 2023.

Basis of Presentation
Unless the context requires otherwise, the terms “Owens Corning,” “Company,” “we” and “our” in these notes 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 2021 and 2020 Consolidated Financial Statements and Notes to the Consolidated Financial Statements to conform to the classifications used in 2022.

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
We recognize revenue as the amount of consideration that we expect to receive in exchange for transferring promised goods or services to customers. We do not adjust the transaction price for the effects of a significant financing component, as the time period between control transfer of goods and services and expected payment is one year or less. At the time of sale, we estimate provisions for different forms of variable consideration (discounts, rebates, returns and other refund liabilities) based on historical experience, current conditions and contractual obligations, as applicable. The estimated transaction price is typically not subject to significant reversals. We adjust these estimates when the most likely amount of consideration we expect to receive changes, although these changes are typically minor. Sales, value-added and other similar taxes that we collect are excluded from revenue.
Many of our customer volume commitments are short-term and our performance obligations are generally limited to single purchase orders. Substantially all of our revenue is recognized at a point-in-time when control of goods transfers to the customer. Control transfer typically occurs when goods are shipped from our facilities or at other predetermined control transfer points (for instance, destination terms or consignment arrangements).

Revenue Recognition (continued)
We typically do not satisfy performance obligations without obtaining an unconditional right to payment from customers and, therefore, do not carry contract asset balances on the Consolidated Balance Sheets. Contract liability balances are recorded separately from receivables on the Consolidated Balance Sheets in either Total current liabilities or Other liabilities, depending on the timing of performance obligation satisfaction.
We sell separately-priced warranties that extend certain product and workmanship coverages beyond our standard product warranty, which is described in Note 12. The up-front consideration on extended warranty contracts is deferred and recognized as revenue over time, based on the respective coverage period, ranging from 16 to 20 years. On an annual basis, we expect to recognize approximately $6 million of revenue associated with these extended warranty contracts. Additionally, in certain limited cases, we receive consideration before goods or services are transferred to the customer. These customer down payments and deposits are deferred, and typically recognized as revenue in the following quarter when we satisfy the related performance obligations.
As of December 31, 2022, our contract liability balances (for extended warranties, down payments and deposits, collectively) totaled $89 million. As of December 31, 2021, our contract liability balances totaled $76 million, of which $17 million was recognized as revenue throughout 2022. As of December 31, 2020, our contract liability balances (for extended warranties, down payments and deposits, collectively) totaled $66 million, of which $17 million was recognized as revenue throughout 2021. As of December 31, 2019, our contract liability balances (for extended warranties, down payments and deposits, collectively) totaled $60 million, of which $19 million was recognized as revenue throughout 2020.
As a practical expedient, we recognize incremental costs of obtaining a contract, if any, as an expense when incurred if the amortization period of the asset would have been one year or less. We do not have any costs to obtain or fulfill a contract that are capitalized under Accounting Standards Codification (ASC) 606.

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. Provisions for warranties 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. 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. We account for shipping and handling activities that occur after control of the related good transfers as fulfillment activities instead of performance obligations. All shipping and handling costs billed to the customer are included as net sales in the Consolidated Statements of Earnings (Loss).

Marketing and Advertising Expenses
Marketing and advertising expenses are included in Marketing and administrative expenses. These costs include advertising and marketing communications, which are expensed the first time the advertisement takes place. Marketing and advertising expenses for the years ended December 31, 2022, 2021 and 2020 were $125 million, $110 million and $98 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 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, Cash Equivalents and Restricted Cash
The Company defines cash and cash equivalents as cash and time deposits with maturities of three months or less when purchased. On the Consolidated Statements of Cash Flows, the total of Cash, cash equivalents and restricted cash includes restricted cash of $8 million, $7 million and $7 million as of December 31, 2022, 2021 and 2020, respectively. Restricted cash primarily represents amounts received from a counterparty related to its performance assurance on an executory contract, and is included in Other current assets on the Consolidated Balance Sheets. These amounts are contractually required to be set aside, and the counterparty can exchange the cash for another form of performance assurance at its discretion.

Accounts Receivable
Trade accounts receivable are recorded at the invoiced amount and do not bear interest. Consistent with the requirements of ASU 2016-13, “Financial Instruments - Credit Losses (Topic 236),” the allowance for credit losses is based on the Company’s assessment of the expected losses of customer accounts. The Company regularly reviews the allowance by considering factors such as historical experience, credit quality, the age of the accounts receivable balances, and current economic conditions that may affect a customer’s ability to pay. Account balances are charged off against the allowance when the Company believes it is probable the receivable will not be recovered.

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 net realizable value and expense estimates are made for excess and obsolete inventories. 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 when the Company does not have a controlling financial interest using the equity method under which the Company’s share of earnings and losses of the affiliate is reflected in earnings, and dividends are credited against the investment in affiliate when declared. Investments in affiliates are recorded in Other non-current assets on the Consolidated Balance Sheets, and as of December 31, 2022 and 2021, the total value of investments was $27 million and $45 million, respectively.

Goodwill and Other Intangible Assets
Goodwill assets are not amortized but are tested for impairment on at least an annual basis. The Company has the option to use a qualitative approach to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying value as a basis for determining whether it is necessary to perform a quantitative test. In the current year, as part of the annual assessment, the Company elected to use the qualitative approach for all of its reporting units.
Events and circumstances we consider in performing the qualitative assessment include macro-economic conditions, market and industry conditions, internal cost factors, and the operational stability and the overall financial performance of the reporting units. When it is determined necessary for the Company to perform the quantitative testing process for goodwill, the Company estimates fair values using a discounted cash flow approach from the perspective of a market participant. Significant assumptions used in the discounted cash flow approach are revenue growth rates and earnings before interest and taxes (“EBIT”) margins used in estimating discrete period cash flow forecasts of the reporting unit, the discount rate, and the long-term revenue growth rate and EBIT margins used in estimating the terminal business value. 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 terminal business value is determined by applying the long-term growth rate to the latest year for which a forecast exists. As part of our goodwill quantitative testing process, we would 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.

Goodwill and Other Intangible Assets (continued)
Other indefinite-lived intangible assets are not amortized but are tested for impairment on at least an annual basis or when determined to have a finite useful life. Substantially all of the indefinite-lived intangible assets are in trademarks and trade names. The Company uses the royalty relief approach to determine whether it is more likely than not that the fair value of these assets is less than its carrying amount. This review is performed annually, or when circumstances arise which indicate there may be impairment. When applying the royalty relief approach, the Company performs a discounted cash flow analysis based on the value derived from owning these trademarks and trade names and being relieved from paying royalty to third parties. Significant assumptions used include the discrete period revenue growth rates, long-term EBIT margins, royalty rates, discount rates, and terminal value.
The inputs for the goodwill and indefinite-lived intangible tests are considered Level 3 inputs under the fair value hierarchy as they are the Company’s own data, and are unobservable in the marketplace. Indefinite-lived intangible assets purchased through acquisition are generally tested qualitatively for impairment in the first year following the acquisition before transitioning to the standard methodology described herein in subsequent years.
Please refer to Note 5 for additional disclosures related to Goodwill and Other Intangible Assets.

Emissions Rights
The Company is allotted carbon emission credit allowances (“emissions rights”) from several of the governments under which it operates. These emissions rights are recorded at market value as of the date of issuance and are classified as Intangible assets on the Consolidated Balance Sheets. When the Company emits more than the allotted amounts, additional emissions rights must be purchased.

Properties and Depreciation
Property, plant and equipment are stated at cost and depreciated over their estimated useful lives using the straight-line method. When assets are disposed or otherwise retired, Property, plant and equipment accounts are relieved of the cost and related accumulated depreciation and any gain or loss is included in the Consolidated Statements of Earnings (Loss).
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 typically represents an annual expense of less than 3% of the outstanding value and is recorded in Cost of sales on the Consolidated Statements of Earnings (Loss).
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 – 15 years
Information systems
5 – 10 years
Equipment
5 – 20 years
Expenditures for normal maintenance and repairs are expensed as incurred.

Asset Impairments
The Company evaluates tangible and intangible long-lived assets for impairment when triggering events have occurred. 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 could be material to the Company’s Consolidated Financial Statements in any given period. Please refer to Note 5 for additional detail on impairment charges recorded in 2022 and 2020.

Supplier Finance Programs
We review supplier terms and conditions on an ongoing basis, and have negotiated payment terms extensions in recent years in connection with our efforts to reduce working capital and improve cash flow. Separate from those terms extension actions, certain of our subsidiaries have entered into paying agency agreements with third-party administrators. These voluntary supply chain finance programs (collectively, the “Programs”) generally give participating suppliers the ability to sell, or otherwise pledge as collateral, their receivables from the Company to the participating financial institutions, at the sole discretion of both the suppliers and financial institutions. The Company is not a party to the arrangements between the suppliers and the financial institutions. The Company’s obligations to its suppliers, including amounts due and scheduled payment dates, are not impacted by the suppliers’ decisions to sell, or otherwise pledge as collateral, amounts under these arrangements. The Company's payment terms to the financial institutions, including the timing and amount of payments, are based on the original supplier invoices. One of our programs includes a parent guarantee to the participating financial institution for a certain U.S. subsidiary that, at the time of the respective program’s inception in 2015, was a guarantor subsidiary of the Company’s Credit Agreement. The obligations are presented as Accounts payable within Total current liabilities on the Consolidated Balance Sheets and all activity related to the obligations is presented within operating activities on the Consolidated Statements of Cash Flow.
The Company's outstanding obligations under the programs for the twelve months ended December 31, 2022 and 2021 are as follows:
Twelve Months Ended December 31,
2022 2021
Confirmed obligations outstanding at the beginning of the year $ 226 $ 170
Invoices confirmed during the year 656 587
Confirmed invoices paid during the year (648) (531)
Confirmed obligations outstanding at the end of the year $ 234 $ 226

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. Please refer to Note 21 for additional disclosures related to Income Taxes.

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 captures and claims 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. Please refer to Notes 15 and 16 for additional disclosures related to Pension Plans and Other Postretirement Benefits, respectively.

Derivative Financial Instruments
The Company recognizes all derivative instruments as either assets or liabilities at fair value on the balance sheet. Please refer to Note 4 for further disclosure on derivatives.
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 contracts and the underlying items being hedged. The change in the fair value of cash flow hedges is deferred in Accumulated other comprehensive income (deficit) (“AOCI”) and is subsequently recognized in Cost of sales (for commodity and foreign currency cash flow hedges) on the Consolidated Statements of Earnings (Loss) in order to mirror the location of the hedged items impacting earnings. Cash settlements for commodity and foreign currency hedges qualifying as cash flow hedges are included in Operating activities in the Consolidated Statements of Cash Flows.

The Company has translation exposure resulting from translating the financial statements of foreign subsidiaries into U.S. Dollars, which is recognized in Currency translation adjustment (a component of AOCI). The Company uses cross-currency forward contracts to hedge portions of the net investment in foreign subsidiaries against fluctuations in foreign exchange rates. The changes in fair values of these derivative instruments are recognized in Currency translation adjustment (a component of AOCI), with recognition of the excluded components amortized to Interest expense, net on the Consolidated Statements of Earnings (Loss). Cash settlements for derivatives qualifying as net investment hedges are included in Investing activities in the Consolidated Statements of Cash Flows.

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), net on the Consolidated Statements of Earnings (Loss), and are substantially offset by net revaluation impacts on foreign currency denominated balance sheet exposures (which are also recorded in Other expenses (income), net). Cash settlements for non-designated derivatives are included in the Consolidated Statements of Cash Flows in the category that is consistent with the nature of the derivative instrument, which is generally the same category as the underlying item being hedged.

Fair Value Measurements
The carrying value of cash and cash equivalents, accounts receivable and short-term debt approximate fair value because of the short-term maturity of the instruments.
Please refer to Notes 4, 14 and 15 for fair value disclosures of derivative financial instruments, long-term debt and pension plans.

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 AOCI 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 recorded in Other expenses (income), net in the Consolidated Statements of Earnings (Loss) as incurred. As discussed in the Derivative Financial Instruments section above, the Company uses non-designated foreign currency derivative financial instruments to mitigate this risk. The Company recorded foreign currency transactional (losses)/gains, net of associated derivative activity, of $(4) million, $1 million and $6 million during the years ended December 31, 2022, 2021, and 2020, respectively. Please refer to Note 4 for additional disclosures related to non-designated derivatives.

Related Party Transactions
In the first quarter of 2021, a related party relationship was established as a result of a member of the Company’s Board of Directors being named an executive officer of one of the Company’s preexisting suppliers. The related party transactions with this supplier consist of the purchase of raw materials. Purchases from the related party supplier were $129 million for the year ended December 31, 2022. As of December 31, 2022, amounts due to the related party supplier were $3 million. Purchases from the related party supplier were $87 million for the year ended December 31, 2021. As of December 31, 2021, amounts due to the related party supplier were $1 million.

Segment Reporting [Abstract]

SEGMENT INFORMATION
The Company has three reportable segments: Composites, Insulation and Roofing. Accounting policies for the segments are the same as those for the Company. The Company’s three reportable segments are defined as follows:
Composites – Within our Composites segment, the Company manufactures, fabricates and sells glass reinforcements in the form of fiber. Glass reinforcement materials are also used by the Composites segment to manufacture and sell high value applications in the form of fabrics, non-wovens and other specialized products.
Insulation – Within our Insulation segment, the Company manufactures and sells thermal and acoustical batts, loosefill insulation, spray foam insulation, foam sheathing and accessories. It also manufactures and sells glass fiber pipe insulation, energy efficient flexible duct media, bonded and granulated mineral wool insulation, cellular glass insulation, and foam insulation used in above- and below-grade construction applications.
Roofing – Within our Roofing segment, the Company manufactures and sells residential roofing shingles, oxidized asphalt materials, roofing components used in residential and commercial construction and specialty applications, and synthetic packaging materials.

NET SALES
The following tables show a disaggregation of our net sales by segment and geographic region (in millions). Corporate eliminations (shown below) largely reflect intercompany sales from Composites to Roofing. External customer sales are attributed to geographic region based upon the location from which the product is sold to the external customer.

Our contracts with customers are broadly similar in nature throughout our reportable segments, but the amount, timing and uncertainty of revenue and cash flows may vary in each reportable segment due to geographic and end-market economic factors.
Sales to major customer - No individual customers accounted for 10% or more of consolidated sales in 2022 or 2020. One customer, which is a customer of both the Roofing and Insulation segments, accounted for $895 million (11%) of consolidated sales in 2021.
In the United States, sales are primarily related to the residential housing market and commercial and industrial applications. Residential market demand is driven by housing starts and repair and remodeling activity (influenced by existing home sales, seasonal home improvement and damage from major storms). Significant portions of our residential products across our three reportable segments are used interchangeably in both new construction and repair and remodeling, and our customers typically distribute (or use) the products for both applications. U.S. commercial and industrial revenues are largely driven by U.S. industrial production growth, commercial construction activity and overall economic conditions in the U.S.
Outside of the United States (Europe, Asia-Pacific and Rest of world), sales are primarily related to commercial and industrial applications and, to a lesser extent, residential applications in certain countries. Throughout the international regions, demand is primarily driven by industrial production growth, commercial construction activity and overall economic conditions in each respective geographical region.
EARNINGS BEFORE INTEREST AND TAXES
Earnings (loss) 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 within Corporate, Other and Eliminations.

Derivative Instruments and Hedging Activities Disclosure [Abstract]

DERIVATIVE FINANCIAL INSTRUMENTS DERIVATIVE FINANCIAL INSTRUMENTS
The Company is exposed to, among other risks, the impact of changes in commodity prices, foreign currency exchange rates, and interest 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, 2022 and 2021, 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.
Derivative Fair Values
Our derivatives consist of natural gas forward swaps, cross-currency swaps, foreign exchange forward contracts and U.S. treasury rate lock agreements, all of which are over-the-counter and not traded through an exchange. The Company uses widely accepted valuation tools to determine fair value, such as discounting cash flows to calculate a present value for the derivatives. The models use Level 2 inputs, such as forward curves and other commonly quoted observable transactions and prices. The fair value of our derivatives and hedging instruments are all classified as Level 2 investments within the three-tier hierarchy.
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 a combination of derivative financial instruments, which qualify as cash flow hedges, and physical contracts to manage forecasted exposure to electricity and natural gas prices. As of December 31, 2022, the notional amounts of these natural gas forward swaps were 8 million MMBTu (or MMBTu equivalent based on U.S. and European indices), compared with the notional amounts of 6 million MMBTu at December 31, 2021.

In March 2020, the Company entered into a $175 million forward U.S. Treasury rate lock agreement to manage the U.S. Treasury portion of its interest rate risk associated with the anticipated issuance of certain 10-year fixed rate senior notes. The Company designated this outstanding forward U.S. Treasury rate lock agreement as a cash flow hedge. The locked fixed rate of this agreement was 0.994%. In September 2022, a gain of $6 million was recognized as a result of a change in the forecasted issuance of certain senior notes. On December 15, 2022, the Company received cash of $37 million upon the settlement of the rate lock agreement, of which $31 million will be amortized as a component of interest expense upon the future issuance of senior notes.
In June 2021, the Company entered into five currency forward contracts with unrelated counterparties with notional amounts totaling $23 million to mitigate against unwanted or anticipated moves in the European Euro exchange rate against the U.S. Dollar, pertaining to forecasted Euro denominated invoices for capital expenditures. The Company has designated each of the individual contracts as cash flow hedges, with the last hedge maturing in December 2022.
Net Investment Hedges
The Company has translation exposure resulting from translating the financial statements of foreign subsidiaries into U.S. Dollars, which is recognized in Currency translation adjustment (a component of AOCI). In the second quarter of 2022, the Company terminated the remaining cross-currency forward contracts related to the hedged portions of the net investment in foreign subsidiaries, resulting in cash proceeds of $11 million.
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. As of December 31, 2022, the Company had notional amounts of $474 million for non-designated derivative financial instruments related to foreign currency exposures in U.S. Dollars primarily related to Brazilian Real, Indian Rupee, Chinese Yuan, European Euro, Hong Kong Dollar, and South Korean Won. In addition, the Company had notional amounts of $111 million for non-designated derivative financial instruments related to foreign currency exposures in European Euro primarily related to the Polish Złoty, Norwegian Krone, and Chinese Yuan.

The annual tests performed in the fourth quarter of 2022 and 2021 resulted in no impairment of goodwill.

In the first quarter of 2020, the Company performed its ongoing assessment to consider whether events or circumstances had occurred that could more likely than not reduce the fair value of a reporting unit below its carrying value. The Company’s significant share price reduction during the onset of the COVID-19 pandemic was determined to be an indicator of impairment under ASC 350. The valuation limitation from the Company’s share price decline, the narrow cushion on the Insulation reporting unit and the high level of near-term macroeconomic uncertainty caused the Company to perform an interim goodwill impairment test as of March 31, 2020 over the Insulation reporting unit.
As part of our quantitative testing process for goodwill of the Insulation reporting unit, we estimated fair values using a discounted cash flow analysis, a form of the income approach, from the perspective of a market participant. Significant assumptions used in the discounted cash flow approach are revenue growth rates and EBIT margins used in estimating discrete period cash flow forecasts of the reporting unit, the discount rate, and the long-term revenue growth rate and EBIT margins used in estimating the terminal business value. The terminal business value is determined by applying the long-term growth rate to the latest year for which a forecast exists.

Based on the results of this interim testing over the Insulation reporting unit, the Company recorded a $944 million pre-tax non-cash impairment charge in the first quarter of 2020. This charge was recorded in Goodwill impairment charge on the Consolidated Statements of Earnings (Loss), and was included in the Corporate, Other and Eliminations reporting category. Consistent with the Company’s adoption of ASU 2017-04 in the first quarter of 2020, the impairment charge was equal to the excess of the Insulation reporting unit’s carrying value over its fair value. The reduction in fair value for the Insulation reporting unit, and corresponding impairment charge, was primarily driven by an increase in the discount rate arising from higher equity risk premiums that reflected significant uncertainty surrounding the effect from the COVID-19 pandemic and a decrease in the reporting unit's forecasted near-term cash flows.

Indefinite-Lived Intangible Assets
The annual tests performed in the fourth quarter of 2022 resulted in impairment of five of the Company's indefinite-lived intangible assets.
Based on the results of this testing, the Company recorded pre-tax non-cash impairment charges totaling $96 million in the fourth quarter of 2022. These charges were recorded in Other expenses (income), net on the Consolidated Statements of Earnings (Loss), and were included in the Corporate, Other and Eliminations reporting category.
Fair values used in testing for potential impairment of our trademarks are calculated using the relief-from-royalty method 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 at a rate based on a market participant discount rate.
These charges included the following within the Insulation segment: a pre-tax impairment charge of $63 million for a trade name used by our European building and technical insulation business due to the effect of a higher discount rate, associated with rising interest rates, and general economic and geopolitical uncertainty within the European markets resulting in a slightly lower profitability outlook; a pre-tax impairment charge of $12 million related to a trademark used on global cellular glass insulation products due to the effect of a higher discount rate, associated with rising interest rates, and general economic and geopolitical uncertainty within the European markets; a pre-tax impairment charge of $8 million for a trademark used on mineral wool insulation products sold in the United States due to forecasted profitability of the product line.
The remaining $13 million pre-tax impairment charge for trademarks used within the components business in our Roofing segment was due to the effect of a higher discount rate, associated with rising interest rates, and forecasted profitability of a specific product line.

The following table presents the remaining carrying values of the impaired trade names and trademarks as of December 31, 2022 (in millions):
Trade names and trademarks December 31, 2022
European building and technical insulation trade name
$ 87
Global cellular glass insulation trademark $ 80
Components branded roofing trademark $ 42
Mineral wool insulation trademark $ —
Components packaging trademark $ —
The fair value of the remaining indefinite-lived intangible assets substantially exceeded the carrying value as of the date of our assessment.
The annual test performed in the fourth quarter of 2021 and 2020 resulted in no impairment of indefinite-lived intangible assets.
In the first quarter of 2020, we performed an interim impairment test of one indefinite-lived trademark and one trade name used by our Insulation segment, based on the macroeconomic conditions that precipitated the interim goodwill impairment test described above.
Based on the results of this testing, the Company recorded pre-tax non-cash impairment charges totaling $43 million in the first quarter of 2020 related to one trademark and one trade name in the Insulation segment. These charges were recorded in Other expenses, net on the Consolidated Statements of Earnings (Loss), and were included in the Corporate, Other and Eliminations reporting category.
A pre-tax impairment charge of $34 million for a trade name used by our European building and technical insulation business was recognized in the first quarter of 2020 due to the combined effect of lower expected sales following an immaterial divestiture in the first quarter of 2020, a decrease in the forecasted near-term cash flows, and a higher discount rate associated with the economic impact and uncertainty from the COVID-19 pandemic. A pre-tax impairment charge of $9 million related to a trademark used on global cellular glass insulation products was recorded in the first quarter of 2020 due to a slightly lower sales outlook and a similarly higher discount rate associated with the economic impact and uncertainty from the COVID-19 pandemic.
Definite-Lived Intangible Assets
The Company amortizes the cost of other intangible assets over their estimated useful lives which, individually, range up to 45 years. The Company's future cash flows are not materially impacted by its ability to extend or renew agreements related to its amortizable intangible assets.
Amortization expense for intangible assets for the years ended December 31, 2022, 2021, and 2020 was $55 million, $49 million, and $48 million, respectively. The estimated amortization expense for intangible assets for the next five years is as follows (in millions):

As a result, we exchanged certain precious metals used in production tooling for certain other precious metals to be used in production tooling. These non-cash exchanges resulted in a net increase to Machinery and equipment of $18 million and $41 million and gains totaling $18 million and $41 million for the twelve months ended December 31, 2022 and 2021, respectively. These gains are included in Other expenses (income), net on the Consolidated Statements of Earnings (Loss) and reflected in the Corporate, Other and Eliminations reporting category. These non-cash investing activities are not included in Net cash flow used for investing activities in the Consolidated Statements of Cash Flows. We do not expect these non-cash exchanges to materially impact our current or future capital expenditure requirements or rate of depletion.
For the years ended December 31, 2022, 2021 and 2020, depreciation expense was $447 million, $429 million and $429 million, respectively, which includes depletion expense related to precious metals used in our production tooling. In 2022, 2021 and 2020, depreciation expense included $26 million, $13 million and $20 million, respectively, of accelerated depreciation related to restructuring actions further explained in Note 13 to the Consolidated Financial Statements.

Leases [Abstract]

LEASES LEASES
The Company leases certain equipment and facilities under both operating and finance leases expiring on various dates through 2050. The nature of these leases generally fall into the following five categories: real estate, material handling equipment, fleet vehicles, office equipment and energy equipment.
For leases with initial terms greater than 12 months, we consider these our right-of-use assets and record the related asset and obligation at the present value of lease payments over the term. For leases with initial terms equal to or less than 12 months, we do not consider them as right-of-use assets and instead consider them short-term lease costs that are recognized on a straight-line basis over the lease term.
Many of our leases include escalation clauses, renewal options and/or termination options that are factored into our determination of lease payments when reasonably certain. These options to extend or terminate a lease are at our discretion. We have elected to take the practical expedient and not separate lease and non-lease components of contracts. We estimate our incremental borrowing rate to discount the lease payments based on information available at lease commencement. Our lease agreements do not contain any material residual value guarantees.

RESTRUCTURING, ACQUISITION AND DIVESTITURE-RELATED COSTS RESTRUCTURING, ACQUISITION AND DIVESTITURE-RELATED COSTS
The Company may incur restructuring, transaction and integration costs related to acquisitions and divestitures, and may incur restructuring and other exit costs in connection with its global cost reduction, productivity initiatives and the Company's growth strategy.

ACQUISITION AND DIVESTITURE-RELATED COSTS

During 2022, the Company incurred $7 million of transaction costs related to its announced acquisitions and divestitures. Please refer to Note 7 and Note 8 of the Consolidated Financial Statements for further information regarding these actions.

RESTRUCTURING RELATED-COSTS

Composites Strategic Realignment Actions
Throughout 2022, the Company took actions to support our growth strategy in building and construction applications and reduce its cost structure within the Composites segment. These actions include converting the DUCS manufacturing facilities located in Anderson, South Carolina and Kimchon, Korea to produce other glass fiber products and exiting a facility in Japan. The Company recorded costs of $9 million associated with these actions in 2022 and expects to incur an immaterial amount of incremental costs related to these actions in 2023.

Roofing Restructuring Actions
In December 2021, the Company took actions to restructure operations within the Roofing segment's components product line by relocating production assets from China to India to allow the business to optimize its manufacturing network and support a tariff mitigation strategy. During 2022, the Company recorded $3 million of charges primarily related to severance and other exit costs. The Company expects to recognize $2 million of incremental charges related to these actions in 2023.

Santa Clara Insulation Site
During the third quarter of 2021, the Company entered into a purchase and sale agreement for the Company's Insulation site in Santa Clara, California. The Company ceased operations at this facility in the fourth quarter of 2022, meeting the assets held for sale criteria, with plans to complete the transaction in the first quarter of 2023. Please refer to Note 9 of the Consolidated Financial Statements for further information. This action is part of the Company's on-going strategy to operate a flexible, cost-efficient manufacturing network and geographically locate its assets to better service its customers. Cumulative cash pre-tax charges associated with the transaction are expected to be in the range of $30 million to $40 million, primarily related to severance and one-time employee termination benefits, demolition costs, and other closing costs. In addition, cumulative non-cash charges are expected to be in the range of $75 million to $85 million, primarily consisting of accelerated depreciation of property, plant and equipment and derecognition of the carrying value of land, which will offset the gross proceeds at closing.

During 2022, the Company recorded $35 million of charges, comprised of $22 million of accelerated depreciation and $13 million of other exit costs, associated with this agreement.
2020 Insulation Restructuring Actions
During the fourth quarter of 2020, the Company took actions to avoid future capital outlays and reduce costs in its global Insulation segment, mainly through decisions to close certain manufacturing facilities in Shanghai, China and Fresno, Texas, and optimize a facility in Parainen, Finland. During 2022, the Company recorded $2 million of charges primarily related to accelerated depreciation. The Company expects to recognize an immaterial amount of incremental charges related to these actions in 2023.

Acquisition-Related Restructuring
Following the acquisitions of Paroc Group Oy (“Paroc”) and Pittsburgh Corning Corporation and Pittsburgh Corning Europe NV (collectively, “Pittsburgh Corning”) into the Company's Insulation segment, the Company took actions to realize expected synergies from the newly acquired operations. The Company does not expect to recognize significant incremental costs related to these actions.

On August 19, 2021, the Company issued a make-whole call to repay the remaining portion of its outstanding 2022 senior notes, and the redemption was completed in the third quarter of 2021. The Company recognized approximately $9 million of loss on extinguishment of debt in the third quarter of 2021 associated with these actions.
On October 31, 2006, the Company issued $550 million of 2036 senior notes. The proceeds of these notes were used to pay certain unsecured and administrative claims, finance general working capital needs and for general corporate purposes.
Collectively, the senior notes above are referred to as the “Senior Notes.” The Senior Notes are general unsecured obligations of the Company and rank pari passu with all existing and future senior unsecured indebtedness of the Company.
The Company has the option to redeem all or part of the Senior Notes at any time at a “make-whole” redemption price. The Company is subject to certain covenants in connection with the issuance of the Senior Notes that it believes are usual and customary. The Company was in compliance with these covenants as of December 31, 2022.
Senior Revolving Credit Facility
The Company has an $800 million senior revolving credit facility (the “Senior Revolving Credit Facility”) that includes both borrowings and letters of credit. Borrowings under the Senior Revolving Credit Facility may be used for general corporate purposes and working capital. The Company has the discretion to borrow under multiple options, which provide for varying terms and interest rates including the United States prime rate, federal funds rate plus a spread or LIBOR plus a spread.
In June 2022, the Senior Revolving Credit Facility was amended to allow the Company to continue to operate in comprehensively-sanctioned countries so long as it is not violating any sanctions. In July 2021, the Senior Revolving Credit Facility was amended to extend the maturity date to July 2026. The new agreement also includes fallback language related to a benchmark reference rate replacement, when a LIBOR transition occurs, and eliminated the minimum required interest expense coverage ratio covenant.
The Senior Revolving Credit Facility contains various covenants, including a maximum allowed leverage ratio, that the Company believes are usual and customary for a senior unsecured credit agreement. The Company was in compliance with these covenants as of December 31, 2022. Please refer to the Credit Facility Utilization section below for liquidity information as of December 31, 2022.
Receivables Securitization Facility
The Company has a Receivables Purchase Agreement (RPA) that is accounted for as secured borrowings in accordance with ASC 860, “Accounting for Transfers and Servicing.” Owens Corning Sales, LLC and Owens Corning Receivables LLC, each a subsidiary of the Company, have a $280 million RPA with certain financial institutions. The Company has the ability to borrow at the lenders' cost of funds, which approximates A-1/P-1 commercial paper rates vs. LIBOR, plus a fixed spread. In April 2021, the securitization facility (the “Receivables Securitization Facility”) was amended to extend the maturity date to April 2024. The new agreement also includes fallback language related to a benchmark reference rate replacement, when a LIBOR transition occurs.
The RPA contains various covenants, including a maximum allowed leverage ratio, that the Company believes are usual and customary for a securitization facility. The Company was in compliance with these covenants as of December 31, 2022. Please refer to the Credit Facility Utilization section below for liquidity information as of December 31, 2022.
Owens Corning Receivables LLC’s sole business consists of the purchase or acceptance through capital contributions of trade receivables and related rights from Owens Corning Sales, LLC and the subsequent retransfer of or granting of a security interest in such trade receivables and related rights to certain purchasers who are party to the RPA. Owens Corning Receivables LLC is a separate legal entity with its own separate creditors who will be entitled, upon its liquidation, to be satisfied out of Owens Corning Receivables LLC’s assets prior to any assets or value in Owens Corning Receivables LLC becoming available to Owens Corning Receivables LLC’s equity holders. The assets of Owens Corning Receivables LLC are not available to pay creditors of the Company or any other affiliates of the Company or Owens Corning Sales, LLC.

PENSION PLANS PENSION PLANS
Pension Plans
The Company sponsors defined benefit pension plans. Under the plans, pension benefits are based on an employee’s years of service and, for certain categories of employees, qualifying compensation. Company contributions to these pension plans are determined by an independent actuary to meet or exceed minimum funding requirements. In our U.S. plan, the unrecognized cost of any retroactive amendments and actuarial gains and losses are amortized over the average remaining life expectancy of inactive participants. In all of our Non-U.S plans, the unrecognized cost of any retroactive amendments and actuarial gains and losses are amortized over the average future service period of plan participants expected to receive benefits.
The following tables provide a reconciliation of the change in the projected benefit obligation, the change in plan assets and the net amount recognized in the Consolidated Balance Sheets (in millions):

For the year ended December 31, 2022, the actuarial gain of $277 million was largely the result of increases in discount rates across all plans. In the U.S. plan, the actuarial gain was primarily driven by the increase in the discount rate. The gain was slightly offset by the unfavorable impact of differences between expected and actual pension experience. In the Non-U.S. plans, the actuarial gain was driven by an increase in the discount rate of the U.K. and Canada plans, partially offset by the unfavorable impact of differences between expected and actual pension experience.

For the year ended December 31, 2021, the actuarial gain of $59 million was largely the result of increases in discount rates across all plans. In the U.S. plan, the actuarial gain was primarily driven by the increase in the discount rate. The gain was slightly offset by the unfavorable impact of updated mortality assumptions. In the Non-U.S. plans, the actuarial gain was driven by an increase in the discount rate of the U.K. and other plans, partially offset by inflation.

(a)    Not applicable due to changes in plan made on August 1, 2009 that were effective beginning January 1, 2010.
The expected return on plan assets assumption is 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. An asset return model is used to develop an expected range of returns on plan investments over a 30 year period, with the expected rate of return selected from a best estimate range within the total range of projected results. The result is then rounded down to the nearest 25 basis points.
Items Measured at Fair Value
The Company classifies and discloses pension plan assets in one of the following three categories:
Level 1: Quoted market prices in active markets for identical assets.
Level 2: Observable market based inputs or unobservable inputs that are corroborated by market data.
Level 3: Unobservable inputs that are not corroborated by market data.

Plan Assets

The tables in this section show pension plan asset fair values and fair value leveling information. The assets are categorized into one of the three levels of the fair value hierarchy or are not subject to leveling, in the case of investments that are valued using the net asset value per share (or its equivalent) practical expedient (“NAV”).

Investment Strategy
The current targeted asset allocation for the United States pension plan is to have 21.5% of assets invested in equities, 68.5% in intermediate and long-term fixed income securities and 10% in other strategies. Assets are rebalanced at least quarterly to conform to policy tolerances. The Company actively evaluates the reasonableness of its asset mix given changes in the projected benefit obligation and market dynamics. Our investment policy and asset mix for the non-United States pension plans varies by location and is based on projected benefit obligation and market dynamics.

Contributions
The Company expects to contribute $25 million in cash to its defined benefit pension plans during 2023. Actual contributions to the plans may change as a result of a variety of factors, including changes in laws that impact funding requirements.
Defined Contribution Plans
The Company sponsors two defined contribution plans which are available to substantially all United States employees. The Company matches a percentage of employee contributions up to a maximum level and contributes up to 2% of an employee’s wages regardless of employee contributions. The Company recognized expense of $57 million, $52 million and $48 million during the years ended December 31, 2022, 2021 and 2020, respectively, related to these plans.
POSTEMPLOYMENT AND POSTRETIREMENT BENEFITS OTHER THAN PENSIONS
The Company maintains health care and life insurance benefit plans for certain retired employees and their dependents. The health care plans in the United States are non-funded and pay either (1) stated percentages of covered medically necessary expenses, after subtracting payments by Medicare or other providers and after stated deductibles have been met, or (2) fixed amounts of medical expense reimbursement.
Salaried employees hired on or before December 31, 2005 become eligible to participate in the United States health care plans upon retirement if they have accumulated 10 years of service after age 45, 48 or 50, depending on the category of employee. For employees hired after December 31, 2005, the Company does not provide subsidized retiree health care. Some of the plans are contributory, with some retiree contributions adjusted annually. The Company has reserved the right to change or eliminate these benefit plans subject to the terms of collective bargaining agreements.

The gain was slightly offset by the unfavorable impact of differences between expected and actual pension experience. In the Non-U.S. plans, the actuarial gain was driven by an increase in the discount rate of the U.K. and Canada plans, partially offset by the unfavorable impact of differences between expected and actual pension experience.

For the year ended December 31, 2021, the actuarial gain of $59 million was largely the result of increases in discount rates across all plans. In the U.S. plan, the actuarial gain was primarily driven by the increase in the discount rate. The gain was slightly offset by the unfavorable impact of updated mortality assumptions. In the Non-U.S. plans, the actuarial gain was driven by an increase in the discount rate of the U.K. and other plans, partially offset by inflation.

(a)    Not applicable due to changes in plan made on August 1, 2009 that were effective beginning January 1, 2010.
The expected return on plan assets assumption is 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. An asset return model is used to develop an expected range of returns on plan investments over a 30 year period, with the expected rate of return selected from a best estimate range within the total range of projected results. The result is then rounded down to the nearest 25 basis points.
Items Measured at Fair Value
The Company classifies and discloses pension plan assets in one of the following three categories:
Level 1: Quoted market prices in active markets for identical assets.
Level 2: Observable market based inputs or unobservable inputs that are corroborated by market data.
Level 3: Unobservable inputs that are not corroborated by market data.

Investment Strategy
The current targeted asset allocation for the United States pension plan is to have 21.5% of assets invested in equities, 68.5% in intermediate and long-term fixed income securities and 10% in other strategies. Assets are rebalanced at least quarterly to conform to policy tolerances. The Company actively evaluates the reasonableness of its asset mix given changes in the projected benefit obligation and market dynamics. Our investment policy and asset mix for the non-United States pension plans varies by location and is based on projected benefit obligation and market dynamics.

2028-2032    $ 357
Contributions
The Company expects to contribute $25 million in cash to its defined benefit pension plans during 2023. Actual contributions to the plans may change as a result of a variety of factors, including changes in laws that impact funding requirements.
Defined Contribution Plans
The Company sponsors two defined contribution plans which are available to substantially all United States employees. The Company matches a percentage of employee contributions up to a maximum level and contributes up to 2% of an employee’s wages regardless of employee contributions. The Company recognized expense of $57 million, $52 million and $48 million during the years ended December 31, 2022, 2021 and 2020, respectively, related to these plans.
POSTEMPLOYMENT AND POSTRETIREMENT BENEFITS OTHER THAN PENSIONS
The Company maintains health care and life insurance benefit plans for certain retired employees and their dependents. The health care plans in the United States are non-funded and pay either (1) stated percentages of covered medically necessary expenses, after subtracting payments by Medicare or other providers and after stated deductibles have been met, or (2) fixed amounts of medical expense reimbursement.
Salaried employees hired on or before December 31, 2005 become eligible to participate in the United States health care plans upon retirement if they have accumulated 10 years of service after age 45, 48 or 50, depending on the category of employee. For employees hired after December 31, 2005, the Company does not provide subsidized retiree health care. Some of the plans are contributory, with some retiree contributions adjusted annually. The Company has reserved the right to change or eliminate these benefit plans subject to the terms of collective bargaining agreements.

CONTINGENT LIABILITIES AND OTHER MATTERS
12 Months Ended

Dec. 31, 2022

Loss Contingency [Abstract]

CONTINGENT LIABILITIES AND OTHER MATTERS CONTINGENT LIABILITIES AND OTHER MATTERS
The Company may be involved in various legal and regulatory proceedings relating to employment, antitrust, tax, product liability, environmental, contracts, intellectual property and other matters (collectively, “Proceedings”). The Company regularly reviews the status of such Proceedings along with legal counsel. Liabilities for such Proceedings are recorded when it is probable that the liability has been incurred and when the amount of the liability can be reasonably estimated. Liabilities are adjusted when additional information becomes available. Management believes that the amount of any reasonably possible losses in excess of any amounts accrued, if any, with respect to such Proceedings or any other known claim, including the matters described below under the caption Environmental Matters (the “Environmental Matters”), are not material to the Company’s financial statements. Management believes that the ultimate disposition of the Proceedings and the Environmental Matters will not have a material adverse effect on the Company’s financial condition. While the likelihood is remote, the disposition of the Proceedings and Environmental Matters could have a material impact on the results of operations, cash flows or liquidity in any given reporting period.
Litigation and Regulatory Proceedings
The Company is involved in litigation and regulatory proceedings from time to time in the regular course of its business. The Company believes that adequate provisions for resolution of all contingencies, claims and pending matters have been made for probable losses that are reasonably estimable.
Environmental Matters

The Company has established policies and procedures designed to ensure that its operations are conducted in compliance with all relevant laws and regulations and that enable the Company to meet its high standards for corporate sustainability and environmental stewardship. Our manufacturing facilities are subject to numerous foreign, federal, state and local laws and regulations relating to the presence of hazardous materials, pollution and protection of the environment, including emissions to air, reductions of greenhouse gases, discharges to water, management of hazardous materials, handling and disposal of solid wastes, use of chemicals in our manufacturing processes, and remediation of contaminated sites. All Company manufacturing facilities are required to use an ISO 14001 or equivalent environmental management system. The Company’s 2030 Sustainability Goals include significant global reductions in energy use, water consumption, waste to landfill, and emissions of greenhouse gases, fine particulate matter, and volatile organic air emissions, and protection of biodiversity.

Owens Corning is involved in remedial response activities and is responsible for environmental remediation at a number of sites, including certain of its currently owned or formerly owned plants. These responsibilities arise under a number of laws, including, but not limited to, the Federal Resource Conservation and Recovery Act, and similar state or local laws pertaining to the management and remediation of hazardous materials and petroleum. The Company has also been named a potentially responsible party under the U.S. Federal Superfund law, or state equivalents, at a number of disposal sites. The Company became involved in these sites as a result of government action or in connection with business acquisitions. As of December 31, 2022, the Company was involved with a total of 23 sites worldwide, including 10 Superfund and state equivalent sites and 13 owned or formerly owned sites. None of the liabilities for these sites are individually significant to the Company.
Remediation activities generally involve a potential range of activities and costs related to soil, groundwater, and sediment contamination. This can include pre-cleanup activities such as fact-finding and investigation, risk assessment, feasibility studies, remedial action design and implementation (where actions may range from monitoring to removal of contaminants, to installation of longer-term remediation systems). A number of factors affect the cost of environmental remediation, including the number of parties involved in a particular site, the determination of the extent of contamination, the length of time the remediation may require, the complexity of environmental regulations, variability in clean-up standards, the need for legal action, and changes in remediation technology. Taking these factors into account, Owens Corning has predicted the costs of remediation reasonably estimated to be paid over a period of years. The Company accrues an amount on an undiscounted basis, consistent with the reasonable estimates of these costs when it is probable that a liability has been incurred. Actual cost may differ from these estimates for the reasons mentioned above. At December 31, 2022, the Company had an accrual totaling $5 million for these costs, of which the current portion is $1 million. Changes in required remediation procedures or timing of those procedures, or discovery of contamination at additional sites, could result in material increases to the Company’s environmental obligations.

Share-Based Payment Arrangement [Abstract]

STOCK COMPENSATION STOCK COMPENSATION
Description of the Plan

On April 18, 2019, the Company's stockholders approved the Owens Corning 2019 Stock Plan (the “2019 Stock Plan”) which replaced the 2016 Stock Plan. The 2019 Stock Plan authorizes grants of stock options, stock appreciation rights, restricted stock awards, restricted stock units, bonus stock awards, performance stock awards and performance stock units. At December 31, 2022, the number of shares remaining available under the 2019 Stock Plan for all stock awards was 2.6 million.

Prior to 2019, employees were eligible to receive stock awards under the Owens Corning 2016 Stock Plan and the Owens Corning 2013 Stock Plan.

Total Stock-Based Compensation Expense

Stock-based compensation expense included in Marketing and administrative expenses in the accompanying Consolidated Statements of Earnings (Loss) is as follows (in millions):
Twelve Months Ended December 31,
2022 2021 2020
Total stock-based compensation expense $ 51 $ 50 $ 41
Income tax benefit recognized on stock-based compensation expense $ 11 $ 14 $ 14

Stock Options
The Company has granted stock options under its stockholder approved stock plans. The Company calculates a weighted-average grant-date fair value using a Black-Scholes valuation model for options granted. Compensation expense for options is measured based on the fair market value of the option on the date of grant, and is recognized on a straight-line basis over a four year vesting period. In general, the exercise price of each option awarded was equal to the closing market price of the Company’s common stock on the date of grant and an option’s maximum term is 10 years. The volatility assumption was based on a benchmark study of our peers prior to 2014. Starting with the options granted in 2014, the volatility was based on the Company’s historic volatility.
The Company has not granted stock options since the year ended December 31, 2014. As of December 31, 2022, there was no unrecognized compensation cost related to stock options and the exercise prices on outstanding stock options was $37.65.
The following table summarizes the Company’s stock option activity in 2022:

Income tax benefit received for stock option awards exercised $ — $ 4 $ —
Restricted Stock Awards and Restricted Stock Units
The Company has granted restricted stock awards and restricted stock units (collectively referred to as “RSUs”) under its stockholder approved stock plans. Compensation expense for restricted stock is measured based on the closing market price of the stock at date of grant and is recognized on a straight-line basis over the vesting period, which is typically three or four years. The Stock Plan allows alternate vesting schedules for death, disability, and retirement.
The weighted average grant date fair value of RSUs granted in 2022, 2021 and 2020 was $90.41, $84.03 and $63.96, respectively.
The following table shows a summary of the Company’s RSU plans:

Balance at December 31, 2022
1,276,160 $ 69.16
As of December 31, 2022, there was $33 million of total unrecognized compensation cost related to RSUs. That cost is expected to be recognized over a weighted-average period of 2.36 years. The total grant date fair value of shares vested during the years ended December 31, 2022, 2021 and 2020 was $22 million, $26 million and $27 million, respectively.
Performance Stock Awards and Performance Stock Units
The Company has granted performance stock awards and performance stock units (collectively referred to as “PSUs”) as a part of its long-term incentive plan. All outstanding performance grants will fully settle in stock. The amount of stock ultimately distributed from the 2022, 2021 and 2020 grants is contingent on meeting internal company-based metrics or an external-based stock performance metric.
In 2022, 2021 and 2020, the Company granted both internal company-based and external-based metric PSUs.
Internal Company-based metrics
The internal company-based metrics vest after a three-year period and are based on various company-based metrics over a three-year period. The amount of stock distributed will vary from 0% to 300% of PSUs awarded depending on performance versus the company-based metrics.
The initial fair value for all internal company-based metric PSUs assumes that the performance goals will be achieved and is based on the grant date stock price. This assumption is monitored quarterly and if it becomes probable that such goals will not be achieved or will be exceeded, compensation expense recognized will be adjusted and previous surplus compensation expense recognized will be reversed or additional expense will be recognized. The expected term represents the period from the grant date to the end of the three-year performance period. Pro-rata vesting may be utilized in the case of death, disability or retirement, and awards, if earned, will be paid at the end of the three-year period.
External based metrics
The external-based metrics vest after a three-year period. Outstanding grants issued in or after 2018 were based on the Company's total stockholder return relative to the performance of the Dow Jones U.S. Construction & Materials Index. The amount of stock distributed will vary from 0% to 200% of PSUs awarded depending on the relative stockholder return performance. The fair value of external-based metric PSUs has been estimated at the grant date using a Monte Carlo simulation that uses various assumptions.
The following table provides a range of these assumptions:
Twelve Months Ended December 31,
2022 2021 2020
Expected volatility 41.65%
42.74% — 43.67%
28.43% — 44.83%

2.31 — 2.90
Grant date fair value of units granted $122.69
$99.19 — $127.37
$68.60 — $76.58
The risk-free interest rate was based on zero coupon United States Treasury bills at the grant date. The expected term represents the period from the grant date to the end of the three-year performance period.
PSU Summary
As of December 31, 2022, there was $19 million total unrecognized compensation cost related to PSUs. That cost is expected to be recognized over a weighted-average period of 1.64 years. The total grant date fair value of shares vested during the years ended December 31, 2022, 2021 and 2020, was $9 million, $8 million and $9 million, respectively.

Employee Stock Purchase Plan
The Owens Corning Employee Stock Purchase Plan (ESPP) is a tax qualified plan under Section 423 of the Internal Revenue Code. The purchase price of shares purchased under the ESPP is equal to 85% of the lower of the fair market value of shares of Owens Corning common stock at the beginning or ending of the offering period, which is a six month period ending on May 31 and November 30 of each year. On April 16, 2020, the Company's stockholders approved the Amended and Restated Owens Corning Employee Stock Purchase Plan which increased the number of shares available for issuance under the plan by 4.2 million shares. As of December 31, 2022, 3.5 million shares remain available for purchase.
Included in total stock-based compensation expense is $6 million, $6 million and $6 million of expense related to the Company's ESPP for the years ended December 31, 2022, 2021 and 2020, respectively. As of December 31, 2022, the Company had $3 million of total unrecognized compensation costs related to the ESPP. Under the outstanding ESPP as of February 14, 2023, employees have contributed $5 million to purchase shares for the current purchase period ending May 31, 2023.

Earnings Per Share [Abstract]

EARNINGS PER SHARE EARNINGS PER SHARE
The following table is a reconciliation of weighted-average shares for calculating basic and diluted earnings (loss) per-share (in millions, except per share amounts):
Twelve Months Ended December 31,
2022 2021 2020
Net earnings (loss) attributable to Owens Corning $ 1,241 $ 995 $ (383)
Weighted-average number of shares outstanding used for basic earnings (loss) per share 96.6 103.5 108.6
Non-vested restricted and performance shares 1.1 0.8 —
Weighted-average number of shares outstanding and common equivalent shares used for diluted earnings (loss) per share 97.7 104.3 108.6
Earnings (loss) per common share attributable to Owens Corning common stockholders:
Basic $ 12.85 $ 9.61 $ (3.53)
Diluted $ 12.70 $ 9.54 $ (3.53)
Basic earnings (loss) per share is calculated by dividing earnings (loss) attributable to Owens Corning by the weighted-average number of shares of the Company’s common stock outstanding during the period. Outstanding shares consist of issued shares less treasury stock.
On February 14, 2022, the Board of Directors approved a share buy-back program under which the Company is authorized to repurchase up to 10 million shares of the Company’s outstanding common stock (the “February 2022 Repurchase Authorization”). The February 2022 Repurchase Authorization is in addition to the 2020 Repurchase Authorization (the 2020 Repurchase Authorization and collectively with the 2022 Repurchase Authorization, the “Repurchase Authorization”). The Company repurchased 9.0 million shares of its common stock for $779 million during the year ended December 31, 2022 under the Repurchase Authorization.

On December 1, 2022, the Board of Directors approved a new share buy-back program under which the Company is authorized to repurchase up to 10 million shares of the Company’s outstanding common stock (the “December 2022 Repurchase Authorization”). The December 2022 Repurchase Authorization is in addition to the February 2022 Repurchase Authorization (together, the “Repurchase Authorization”). The Repurchase Authorization enables the Company to repurchase shares through the open market, privately negotiated, or other transactions. The actual number of shares repurchased will depend on timing, market conditions and other factors and will be at the Company's discretion. As of December 31, 2022, 14.4 million shares remained available for repurchase under the Repurchase Authorization.

For the year ended December 31, 2022, the Company did not have any non-vested restricted shares or non-vested performance shares that had an anti-dilutive effect on earnings per share. For the year ended December 31, 2021, the number of shares used in the calculation of diluted earnings per share did not include 0.1 million non-vested performance shares due to their anti-dilutive effect. For the year ended December 31, 2020, diluted earnings per share was equal to basic earnings per share due to the net loss attributable to Owens Corning.

In the first quarter of 2020, the company recorded a non-cash charge related to the impairment of goodwill which was largely non-deductible resulting in a substantial negative impact to our effective tax rate.
In addition, non-cash charges were recorded in 2020 related to valuation allowance adjustments against certain deferred tax assets recorded in our French, Indian and Other foreign legal entities due to volatility in the markets we serve from the COVID-19 pandemic.
In December 2020, the company completed an intercompany restructuring that resulted in the transfer of certain intellectual property rights, held by wholly owned foreign subsidiaries, to the U.S. The intellectual property rights transferred to the U.S. resulted in a step-up in the tax basis for U.S. tax purposes which resulted in the company recognizing a deferred tax asset of $37 million and tax expense of $5 million. The recognized tax benefit of $37 million is amortizable for U.S. tax purposes over a fifteen-year period.
On July 20, 2020 the Internal Revenue Service (IRS) issued final regulations under IRC Section 951A permitting a taxpayer to elect to exclude, from its inclusion of global intangible low-taxed income (GILTI), income subject to a high foreign effective tax rate. As a result of the final regulations, the company recorded a net non-cash income tax benefit of $13 million in the third quarter of 2020 relating to the 2018 and 2019 tax years.
The Company continues to assert indefinite reinvestment in accordance with ASC 740 based on the laws as of enactment of the Tax Act. As of December 31, 2022, the Company has not provided for withholding or income taxes on approximately $1.8 billion of undistributed reserves of its foreign subsidiaries and affiliates as they are considered by management to be permanently reinvested. Quantification of the deferred tax liability associated with these undistributed reserves is not practicable.

The following table summarizes the amount and expiration dates of our deferred tax assets related to operating loss and tax credit carryforwards and foreign tax credit carryforwards at December 31, 2022 (in millions) (a):
Expiration
Dates Amounts
Domestic loss and tax credit carryforwards 2023-2036 $ 91
Foreign loss and tax credit carryforwards (b) 2023 - Indefinite 69
Total operating loss and tax credit carryforwards $ 160

(a)The use of certain of the Company's losses and credits is limited pursuant to sections 382 and 383 of the Internal Revenue Code which 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 more than 50% in the ownership positions of certain stockholders during a rolling three-year period. The Company believes that these limitations will not result in a forfeiture of the carryforwards.
(b)The foreign net operating losses are related to various jurisdictions that provide for both indefinite carryforward periods and others with carryforward periods that range from the tax years 2023 to 2036.
Deferred income taxes are provided for temporary differences between amounts of assets and liabilities for financial reporting purposes and the basis of such assets and liabilities as measured under enacted tax laws and regulations, as well as NOLs, tax credits and other carryforwards. A valuation allowance will be recorded to reduce deferred tax assets if, based on all available evidence, it is considered more likely than not that some portion or all of the recorded deferred tax assets will not be realized in future periods. To the extent the reversal of deferred tax liabilities is relied upon in our assessment of the realizability of deferred tax assets, they will reverse in the same period and jurisdiction as the temporary differences giving rise to the deferred tax assets. As of December 31, 2022, the Company had net deferred tax liabilities before valuation allowances of $243 million.
The valuation allowance of $129 million as of December 31, 2022 is related to U.S. federal foreign tax credits (FTCs) and certain state and foreign jurisdictions. The realization of deferred tax assets depends on achieving a certain minimum level of future taxable income. Management currently believes that it is at least reasonably possible that the minimum level of taxable income will be met within the next 12 months to reduce the valuation allowance of certain foreign jurisdictions by a range of zero to $3 million. The valuation allowance of $132 million as of December 31, 2021 is related to U.S. federal FTC's and certain state and foreign jurisdictions.
The Company, or one of its subsidiaries, files income tax returns in the United States and other foreign jurisdictions. The Company is no longer subject to U.S. federal tax examinations for years before 2019 or state and foreign examinations for years before 2016. Due to the potential for resolution of federal, state and foreign examinations, and the expiration of various statutes of limitation, it is reasonably possible that the gross unrecognized tax benefits balance may change within the next 12 months by a range of zero to $5 million.
A reconciliation of the beginning and ending amounts of unrecognized tax benefits is as follows (in millions):
Twelve Months Ended December 31,
2022 2021 2020
Balance at beginning of period $ 74 $ 76 $ 79

Settlements (1) (1) (1)
Expiration of statute of limitations (3) (1) (3)
Impact of currency changes (1) — —
Balance at end of period $ 71 $ 74 $ 76
If these unrecognized tax benefits were to be recognized as of December 31, 2022, the Company’s income tax expense would decrease by about $52 million.
The Company classifies all interest and penalties as income tax expense. As of December 31, 2022, 2021 and 2020, and for the periods then ended, the Company recognized $7 million, $7 million and $7 million, respectively, in liabilities for tax related interest and penalties on its Consolidated Balance Sheets and $1 million, $2 million and less than $1 million, respectively, of interest and penalty expense on its Consolidated Statements of Earnings (Loss).

BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)
12 Months Ended

Dec. 31, 2022

Accounting Policies [Abstract]

Basis of Accounting, Policy Basis of PresentationUnless the context requires otherwise, the terms “Owens Corning,” “Company,” “we” and “our” in these notes 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 Principles of ConsolidationThe Consolidated Financial Statements of the Company include the accounts of majority-owned subsidiaries. Intercompany accounts and transactions are eliminated.

Reclassifications ReclassificationsCertain reclassifications have been made to the 2021 and 2020 Consolidated Financial Statements and Notes to the Consolidated Financial Statements to conform to the classifications used in 2022.

Use of Estimates and Assumptions Use of Estimates and AssumptionsThe 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 Recognition
We recognize revenue as the amount of consideration that we expect to receive in exchange for transferring promised goods or services to customers. We do not adjust the transaction price for the effects of a significant financing component, as the time period between control transfer of goods and services and expected payment is one year or less. At the time of sale, we estimate provisions for different forms of variable consideration (discounts, rebates, returns and other refund liabilities) based on historical experience, current conditions and contractual obligations, as applicable. The estimated transaction price is typically not subject to significant reversals. We adjust these estimates when the most likely amount of consideration we expect to receive changes, although these changes are typically minor. Sales, value-added and other similar taxes that we collect are excluded from revenue.
Many of our customer volume commitments are short-term and our performance obligations are generally limited to single purchase orders. Substantially all of our revenue is recognized at a point-in-time when control of goods transfers to the customer. Control transfer typically occurs when goods are shipped from our facilities or at other predetermined control transfer points (for instance, destination terms or consignment arrangements).

Revenue Recognition (continued)
We typically do not satisfy performance obligations without obtaining an unconditional right to payment from customers and, therefore, do not carry contract asset balances on the Consolidated Balance Sheets. Contract liability balances are recorded separately from receivables on the Consolidated Balance Sheets in either Total current liabilities or Other liabilities, depending on the timing of performance obligation satisfaction.
We sell separately-priced warranties that extend certain product and workmanship coverages beyond our standard product warranty, which is described in Note 12. The up-front consideration on extended warranty contracts is deferred and recognized as revenue over time, based on the respective coverage period, ranging from 16 to 20 years. On an annual basis, we expect to recognize approximately $6 million of revenue associated with these extended warranty contracts. Additionally, in certain limited cases, we receive consideration before goods or services are transferred to the customer. These customer down payments and deposits are deferred, and typically recognized as revenue in the following quarter when we satisfy the related performance obligations.
As of December 31, 2022, our contract liability balances (for extended warranties, down payments and deposits, collectively) totaled $89 million. As of December 31, 2021, our contract liability balances totaled $76 million, of which $17 million was recognized as revenue throughout 2022. As of December 31, 2020, our contract liability balances (for extended warranties, down payments and deposits, collectively) totaled $66 million, of which $17 million was recognized as revenue throughout 2021. As of December 31, 2019, our contract liability balances (for extended warranties, down payments and deposits, collectively) totaled $60 million, of which $19 million was recognized as revenue throughout 2020.
As a practical expedient, we recognize incremental costs of obtaining a contract, if any, as an expense when incurred if the amortization period of the asset would have been one year or less. We do not have any costs to obtain or fulfill a contract that are capitalized under Accounting Standards Codification (ASC) 606.

Cost of Sales Cost of SalesCost 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. Provisions for warranties 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. 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. We account for shipping and handling activities that occur after control of the related good transfers as fulfillment activities instead of performance obligations. 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 Advertising ExpensesMarketing and advertising expenses are included in Marketing and administrative expenses. These costs include advertising and marketing communications, which are expensed the first time the advertisement takes place.

Science and Technology Expenses Science and Technology ExpensesThe 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 per Share Earnings per ShareBasic 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, Cash Equivalents and Restricted Cash Cash, Cash Equivalents and Restricted CashThe Company defines cash and cash equivalents as cash and time deposits with maturities of three months or less when purchased.

Accounts Receivable Accounts ReceivableTrade accounts receivable are recorded at the invoiced amount and do not bear interest. Consistent with the requirements of ASU 2016-13, “Financial Instruments - Credit Losses (Topic 236),” the allowance for credit losses is based on the Company’s assessment of the expected losses of customer accounts. The Company regularly reviews the allowance by considering factors such as historical experience, credit quality, the age of the accounts receivable balances, and current economic conditions that may affect a customer’s ability to pay. Account balances are charged off against the allowance when the Company believes it is probable the receivable will not be recovered.

Inventory Valuation Inventory ValuationInventory 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 net realizable value and expense estimates are made for excess and obsolete inventories. Cost is determined by the first-in, first-out (“FIFO”) method.

Investments in Affiliates Investments in AffiliatesThe Company accounts for investments in affiliates of 20% to 50% ownership when the Company does not have a controlling financial interest using the equity method under which the Company’s share of earnings and losses of the affiliate is reflected in earnings, and dividends are credited against the investment in affiliate when declared.

Goodwill and Other Intangible Assets Goodwill and Other Intangible Assets
Goodwill assets are not amortized but are tested for impairment on at least an annual basis. The Company has the option to use a qualitative approach to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying value as a basis for determining whether it is necessary to perform a quantitative test. In the current year, as part of the annual assessment, the Company elected to use the qualitative approach for all of its reporting units.
Events and circumstances we consider in performing the qualitative assessment include macro-economic conditions, market and industry conditions, internal cost factors, and the operational stability and the overall financial performance of the reporting units. When it is determined necessary for the Company to perform the quantitative testing process for goodwill, the Company estimates fair values using a discounted cash flow approach from the perspective of a market participant. Significant assumptions used in the discounted cash flow approach are revenue growth rates and earnings before interest and taxes (“EBIT”) margins used in estimating discrete period cash flow forecasts of the reporting unit, the discount rate, and the long-term revenue growth rate and EBIT margins used in estimating the terminal business value. 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 terminal business value is determined by applying the long-term growth rate to the latest year for which a forecast exists. As part of our goodwill quantitative testing process, we would 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.

Goodwill and Other Intangible Assets (continued)
Other indefinite-lived intangible assets are not amortized but are tested for impairment on at least an annual basis or when determined to have a finite useful life. Substantially all of the indefinite-lived intangible assets are in trademarks and trade names. The Company uses the royalty relief approach to determine whether it is more likely than not that the fair value of these assets is less than its carrying amount. This review is performed annually, or when circumstances arise which indicate there may be impairment. When applying the royalty relief approach, the Company performs a discounted cash flow analysis based on the value derived from owning these trademarks and trade names and being relieved from paying royalty to third parties. Significant assumptions used include the discrete period revenue growth rates, long-term EBIT margins, royalty rates, discount rates, and terminal value.
The inputs for the goodwill and indefinite-lived intangible tests are considered Level 3 inputs under the fair value hierarchy as they are the Company’s own data, and are unobservable in the marketplace. Indefinite-lived intangible assets purchased through acquisition are generally tested qualitatively for impairment in the first year following the acquisition before transitioning to the standard methodology described herein in subsequent years.
Please refer to Note 5 for additional disclosures related to Goodwill and Other Intangible Assets.

Emissions Rights
The Company is allotted carbon emission credit allowances (“emissions rights”) from several of the governments under which it operates. These emissions rights are recorded at market value as of the date of issuance and are classified as Intangible assets on the Consolidated Balance Sheets. When the Company emits more than the allotted amounts, additional emissions rights must be purchased.

Properties and Depreciation Properties and Depreciation
Property, plant and equipment are stated at cost and depreciated over their estimated useful lives using the straight-line method. When assets are disposed or otherwise retired, Property, plant and equipment accounts are relieved of the cost and related accumulated depreciation and any gain or loss is included in the Consolidated Statements of Earnings (Loss).
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 typically represents an annual expense of less than 3% of the outstanding value and is recorded in Cost of sales on the Consolidated Statements of Earnings (Loss).
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 – 15 years
Information systems
5 – 10 years
Equipment
5 – 20 years
Expenditures for normal maintenance and repairs are expensed as incurred.

Asset Impairments Asset ImpairmentsThe Company evaluates tangible and intangible long-lived assets for impairment when triggering events have occurred. 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 could be material to the Company’s Consolidated Financial Statements in any given period. Please refer to Note 5 for additional detail on impairment charges recorded in 2022 and 2020.

Supplier Finance Programs

Supplier Finance Programs
We review supplier terms and conditions on an ongoing basis, and have negotiated payment terms extensions in recent years in connection with our efforts to reduce working capital and improve cash flow. Separate from those terms extension actions, certain of our subsidiaries have entered into paying agency agreements with third-party administrators. These voluntary supply chain finance programs (collectively, the “Programs”) generally give participating suppliers the ability to sell, or otherwise pledge as collateral, their receivables from the Company to the participating financial institutions, at the sole discretion of both the suppliers and financial institutions. The Company is not a party to the arrangements between the suppliers and the financial institutions. The Company’s obligations to its suppliers, including amounts due and scheduled payment dates, are not impacted by the suppliers’ decisions to sell, or otherwise pledge as collateral, amounts under these arrangements. The Company's payment terms to the financial institutions, including the timing and amount of payments, are based on the original supplier invoices. One of our programs includes a parent guarantee to the participating financial institution for a certain U.S. subsidiary that, at the time of the respective program’s inception in 2015, was a guarantor subsidiary of the Company’s Credit Agreement. The obligations are presented as Accounts payable within Total current liabilities on the Consolidated Balance Sheets and all activity related to the obligations is presented within operating activities on the Consolidated Statements of Cash Flow.
The Company's outstanding obligations under the programs for the twelve months ended December 31, 2022 and 2021 are as follows:
Twelve Months Ended December 31,
2022 2021
Confirmed obligations outstanding at the beginning of the year $ 226 $ 170
Invoices confirmed during the year 656 587
Confirmed invoices paid during the year (648) (531)
Confirmed obligations outstanding at the end of the year $ 234 $ 226

Income Taxes Income TaxesThe 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. Please refer to Note 21 for additional disclosures related to Income Taxes.

Taxes Collected From Customers and Remitted to Government Authorities and Taxes Paid to Vendors Taxes Collected from Customers and Remitted to Government Authorities and Taxes Paid to VendorsTaxes 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 captures and claims 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 Pension and Other Postretirement BenefitsAccounting 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. Please refer to Notes 15 and 16 for additional disclosures related to Pension Plans and Other Postretirement Benefits, respectively.

Derivative Financial Instruments

Derivative Financial Instruments
The Company recognizes all derivative instruments as either assets or liabilities at fair value on the balance sheet. Please refer to Note 4 for further disclosure on derivatives.
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 contracts and the underlying items being hedged. The change in the fair value of cash flow hedges is deferred in Accumulated other comprehensive income (deficit) (“AOCI”) and is subsequently recognized in Cost of sales (for commodity and foreign currency cash flow hedges) on the Consolidated Statements of Earnings (Loss) in order to mirror the location of the hedged items impacting earnings. Cash settlements for commodity and foreign currency hedges qualifying as cash flow hedges are included in Operating activities in the Consolidated Statements of Cash Flows.

The Company has translation exposure resulting from translating the financial statements of foreign subsidiaries into U.S. Dollars, which is recognized in Currency translation adjustment (a component of AOCI). The Company uses cross-currency forward contracts to hedge portions of the net investment in foreign subsidiaries against fluctuations in foreign exchange rates. The changes in fair values of these derivative instruments are recognized in Currency translation adjustment (a component of AOCI), with recognition of the excluded components amortized to Interest expense, net on the Consolidated Statements of Earnings (Loss). Cash settlements for derivatives qualifying as net investment hedges are included in Investing activities in the Consolidated Statements of Cash Flows.
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), net on the Consolidated Statements of Earnings (Loss), and are substantially offset by net revaluation impacts on foreign currency denominated balance sheet exposures (which are also recorded in Other expenses (income), net). Cash settlements for non-designated derivatives are included in the Consolidated Statements of Cash Flows in the category that is consistent with the nature of the derivative instrument, which is generally the same category as the underlying item being hedged.

Fair Value Measurements Fair Value MeasurementsThe carrying value of cash and cash equivalents, accounts receivable and short-term debt approximate fair value because of the short-term maturity of the instruments. Please refer to Notes 4, 14 and 15 for fair value disclosures of derivative financial instruments, long-term debt and pension plans.

Foreign Currency Foreign CurrencyThe 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 AOCI 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 recorded in Other expenses (income), net in the Consolidated Statements of Earnings (Loss) as incurred.

Summary of Operating Loss and Tax Credit Carryforwards
The following table summarizes the amount and expiration dates of our deferred tax assets related to operating loss and tax credit carryforwards and foreign tax credit carryforwards at December 31, 2022 (in millions) (a):
Expiration
Dates Amounts
Domestic loss and tax credit carryforwards 2023-2036 $ 91
Foreign loss and tax credit carryforwards (b) 2023 - Indefinite 69
Total operating loss and tax credit carryforwards $ 160

(a)The use of certain of the Company's losses and credits is limited pursuant to sections 382 and 383 of the Internal Revenue Code which 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 more than 50% in the ownership positions of certain stockholders during a rolling three-year period. The Company believes that these limitations will not result in a forfeiture of the carryforwards.(b)The foreign net operating losses are related to various jurisdictions that provide for both indefinite carryforward periods and others with carryforward periods that range from the tax years 2023 to 2036.

Business Combination and Asset Acquisition [Abstract]
ACQUISITIONS	ACQUISITIONSOn September 1, 2022, the Company acquired the remaining 50% interest in Fiberteq, LLC (“Fiberteq”), the joint venture between Owens Corning and IKO Industries, Ltd, which produces high-quality wet-formed fiberglass mat for roofing applications for $140 million, net of cash acquired. The acquisition advances the Composites strategy to focus on high-value material solutions and expands Owens Corning's capacity to produce non-woven mat. The Company's 50% interest in Fiberteq was accounted for as an equity-method investment and had a carrying value of $17 million at the acquisition date. The Company used the discounted cash flow method to remeasure the previously held equity method investment to its fair value of $147 million, resulting in the recognition of a gain of $130 million, which is recorded in Gain on equity method investment on the Consolidated Statements of Earnings (Loss). The operating results and a preliminary purchase price allocation for Fiberteq have been included in the Composites segment within the Consolidated Financial Statements since the date of the acquisition. The Company is continuing to obtain information to complete its valuation of certain assets and liabilities. During the year ended December 31, 2022, the Company recorded immaterial measurement period adjustments to the purchase price allocation. The preliminary purchase price allocation included $58 million in intangible assets, which primarily consists of customer relationships with an estimated weighted average life of 3 years, a $62 million unfavorable contract liability and $243 million in goodwill, of which 50% of the goodwill is tax deductible. The factors contributing to the recognition of the amount of goodwill are based on several strategic and synergistic benefits that are expected to be realized from the acquisition. The pro-forma effect of this acquisition on revenues and earnings was not material. On August 1, 2022, the Company acquired Natural Polymers, LLC (“Natural Polymers”), an innovative manufacturer of spray polyurethane foam insulation for building and construction applications for approximately $111 million, net of cash acquired. The acquisition advances the Owens Corning strategy to strengthen the Company's core building and construction products and expand its addressable markets into higher-growth segments. The operating results and a preliminary purchase price allocation for Natural Polymers have been included in the Insulation segment within the Consolidated Financial Statements since the date of the acquisition. The Company is continuing to obtain information to complete its valuation of certain assets and liabilities. During the year ended December 31, 2022, the Company recorded immaterial measurement period adjustments to the purchase price allocation. The preliminary purchase price allocation included $44 million in intangible assets and $62 million in goodwill, of which all is tax deductible. The intangible assets consist of definite-lived trademarks of $5 million with an estimated weighted average life of 10 years, technology of $12 million with an estimated weighted average life of 6 years and customer relationships of $27 million with an estimated weighted average life of 17 years. The factors contributing to the recognition of the amount of goodwill are based on several strategic and synergistic benefits that are expected to be realized from the acquisition. The pro-forma effect of this acquisition on revenues and earnings was not material. On June 1, 2022, the Company acquired all of the outstanding assets of WearDeck®, a premium producer of composite weather-resistant decking for commercial and residential applications, for approximately $133 million, net of cash acquired. The acquisition advances the Composites business growth strategy to focus on high-value material solutions within the building and construction industry. The operating results and a preliminary purchase price allocation for WearDeck® have been included in the Composites segment within the Consolidated Financial Statements since the date of the acquisition. The Company is continuing to obtain information to complete its valuation of certain assets and liabilities. During the year ended December 31, 2022, the Company recorded immaterial measurement period adjustments to the purchase price allocation. The preliminary purchase price allocation included $38 million in intangible assets and $68 million in goodwill, of which $61 million is tax deductible. The intangible assets consist of definite-lived trademarks of $7 million with an estimated weighted average life of 10 years, technology of $10 million with an estimated weighted average life of 11 years and customer relationships of $21 million with an estimated weighted average life of 15 years. The factors contributing to the recognition of the amount of goodwill are based on several strategic and synergistic benefits that are expected to be realized from the acquisition. The pro-forma effect of this acquisition on revenues and earnings was not material. On May 23, 2022, Owens Corning and Pultron Composites (“Pultron”) formed a joint venture (the “JV”) to manufacture and sell fiberglass rebar. The Company contributed approximately $47 million to acquire a 65.5% controlling interest and has established a redeemable noncontrolling interest of $25 million related to Pultron, the minority holder. The JV expands Owens Corning’s capability to produce high-value material solutions by combining the Company’s glass-fiber material technology, channel access and extensive industry experience with Pultron’s manufacturing expertise and process efficiency. The fully consolidated operating results and a preliminary purchase price allocation for the JV have been included in the Company’s Composites segment within the Consolidated Financial Statements since the date of the formation of the JV. Subsequent to the JV formation, the JV acquired assets and technology from Pultron for approximately $65 million. The Company is continuing to obtain information to complete its valuation of certain assets and liabilities. The preliminary purchase price allocation included $15 million in intangible assets, consisting of technology, with an estimated weighted average life of 15 years and $42 million in goodwill, of which $37 million is tax deductible. The factors contributing to the recognition of the amount of goodwill are based on several strategic and synergistic benefits that are expected to be realized from the acquisition. The pro-forma effect of this acquisition on revenues and earnings was not material. On July 13, 2021, the Company acquired vliepa GmbH (“vliepa”), which specializes in the coating, printing, and finishing of non-wovens, paper, and film for the building materials industry in Europe, for $42 million, net of cash acquired.

The operating results for vliepa have been included in the Company’s Composites segment within the Consolidated Financial Statements since the date of the acquisition. The acquisition resulted in the recognition of $13 million in intangible assets, primarily consisting of customer relationships with an estimated weighted average life of 12 years, and $16 million in goodwill. The pro-forma effect of this acquisition on revenues and earnings was not material.

CONTINGENT LIABILITIES AND OTHER MATTERS	12 Months Ended
CONTINGENT LIABILITIES AND OTHER MATTERS	Dec. 31, 2022
Loss Contingency [Abstract]
CONTINGENT LIABILITIES AND OTHER MATTERS	CONTINGENT LIABILITIES AND OTHER MATTERS The Company may be involved in various legal and regulatory proceedings relating to employment, antitrust, tax, product liability, environmental, contracts, intellectual property and other matters (collectively, “Proceedings”). The Company regularly reviews the status of such Proceedings along with legal counsel. Liabilities for such Proceedings are recorded when it is probable that the liability has been incurred and when the amount of the liability can be reasonably estimated. Liabilities are adjusted when additional information becomes available. Management believes that the amount of any reasonably possible losses in excess of any amounts accrued, if any, with respect to such Proceedings or any other known claim, including the matters described below under the caption Environmental Matters (the “Environmental Matters”), are not material to the Company’s financial statements. Management believes that the ultimate disposition of the Proceedings and the Environmental Matters will not have a material adverse effect on the Company’s financial condition. While the likelihood is remote, the disposition of the Proceedings and Environmental Matters could have a material impact on the results of operations, cash flows or liquidity in any given reporting period. Litigation and Regulatory Proceedings The Company is involved in litigation and regulatory proceedings from time to time in the regular course of its business. The Company believes that adequate provisions for resolution of all contingencies, claims and pending matters have been made for probable losses that are reasonably estimable. Environmental Matters The Company has established policies and procedures designed to ensure that its operations are conducted in compliance with all relevant laws and regulations and that enable the Company to meet its high standards for corporate sustainability and environmental stewardship. Our manufacturing facilities are subject to numerous foreign, federal, state and local laws and regulations relating to the presence of hazardous materials, pollution and protection of the environment, including emissions to air, reductions of greenhouse gases, discharges to water, management of hazardous materials, handling and disposal of solid wastes, use of chemicals in our manufacturing processes, and remediation of contaminated sites. All Company manufacturing facilities are required to use an ISO 14001 or equivalent environmental management system. The Company’s 2030 Sustainability Goals include significant global reductions in energy use, water consumption, waste to landfill, and emissions of greenhouse gases, fine particulate matter, and volatile organic air emissions, and protection of biodiversity. Owens Corning is involved in remedial response activities and is responsible for environmental remediation at a number of sites, including certain of its currently owned or formerly owned plants. These responsibilities arise under a number of laws, including, but not limited to, the Federal Resource Conservation and Recovery Act, and similar state or local laws pertaining to the management and remediation of hazardous materials and petroleum. The Company has also been named a potentially responsible party under the U.S. Federal Superfund law, or state equivalents, at a number of disposal sites. The Company became involved in these sites as a result of government action or in connection with business acquisitions. As of December 31, 2022, the Company was involved with a total of 23 sites worldwide, including 10 Superfund and state equivalent sites and 13 owned or formerly owned sites. None of the liabilities for these sites are individually significant to the Company. Remediation activities generally involve a potential range of activities and costs related to soil, groundwater, and sediment contamination. This can include pre-cleanup activities such as fact-finding and investigation, risk assessment, feasibility studies, remedial action design and implementation (where actions may range from monitoring to removal of contaminants, to installation of longer-term remediation systems). A number of factors affect the cost of environmental remediation, including the number of parties involved in a particular site, the determination of the extent of contamination, the length of time the remediation may require, the complexity of environmental regulations, variability in clean-up standards, the need for legal action, and changes in remediation technology. Taking these factors into account, Owens Corning has predicted the costs of remediation reasonably estimated to be paid over a period of years. The Company accrues an amount on an undiscounted basis, consistent with the reasonable estimates of these costs when it is probable that a liability has been incurred. Actual cost may differ from these estimates for the reasons mentioned above. At December 31, 2022, the Company had an accrual totaling $5 million for these costs, of which the current portion is $1 million. Changes in required remediation procedures or timing of those procedures, or discovery of contamination at additional sites, could result in material increases to the Company’s environmental obligations.
