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.
