Accounting Policies [Abstract]
Summary of Accounting Policies	Summary of Accounting Policies Revenue Recognition — Recognition of revenue requires evidence of a contract, probable collection of sales proceeds and completion of substantially all performance obligations. The Company acts as the principal in its customer arrangements and therefore records revenue on a gross basis. The majority of the Company’s contracts have a single performance obligation — the promise to transfer goods. Shipping is considered immaterial in the context of the overall customer arrangement and damages or loss of goods in transit are rare. Therefore, shipping is not deemed a separately recognized performance obligation. Revenues from sales of products, including tenders, are recognized at a point in time when control of the goods is transferred to the customer, which the Company has determined is when title and risks and rewards of ownership transfer to the customer and the Company is entitled to payment. The nature of the Company’s business gives rise to several types of variable consideration including discounts and returns, which are estimated at the time of sale generally using the expected value method, although the most likely amount method is used for prompt pay discounts. In the United States, sales discounts are issued to customers at the point-of-sale, through an intermediary wholesaler (known as chargebacks), or in the form of rebates. Additionally, sales are generally made with a limited right of return under certain conditions. Revenues are recorded net of provisions for sales discounts and returns, which are established at the time of sale. In addition, revenues are recorded net of time value of money discounts if collection of accounts receivable is expected to be in excess of one year. Chargebacks are discounts that occur when a contracted customer purchases through an intermediary wholesaler. The contracted customer generally purchases product from the wholesaler at its contracted price plus a mark-up. The wholesaler, in turn, charges the Company back for the difference between the price initially paid by the wholesaler and the contract price paid to the wholesaler by the customer. The Company estimates the provision for chargebacks based on expected sell-through levels by the Company’s wholesale customers to contracted customers, as well as estimated wholesaler inventory levels. Rebates are amounts owed based upon definitive contractual agreements or legal requirements with private sector, (Managed Care), and public sector (Medicaid and Medicare Part D) benefit providers, after the final dispensing of the product by a pharmacy to a benefit plan participant. The provision for rebates is based on expected patient usage, as well as inventory levels in the distribution channel to determine the contractual obligation to the benefit providers. The Company uses historical customer segment utilization mix, sales forecasts, changes to product mix and price, inventory levels in the distribution channel, government pricing calculations and prior payment history to estimate the expected provision. The U.S. provision for aggregate customer discounts covering chargebacks and rebates was $2.0 billion in 2021, $1.8 billion in 2020, and $1.9 billion in 2019. Amounts accrued for aggregate customer discounts are evaluated on a quarterly basis through comparison of information provided by the wholesalers, health maintenance organizations, pharmacy benefit managers, federal and state agencies, and other customers to the amounts accrued. The accrued balances relative to the provisions for chargebacks and rebates in the United States included in Accounts receivable and Accrued and other current liabilities were $54 million and $275 million, respectively, at December 31, 2021 and $41 million and $302 million, respectively, at December 31, 2020. Outside of the United States, variable consideration in the form of discounts and rebates are a combination of commercially-driven discounts in highly competitive product classes, discounts required to gain or maintain reimbursement, or legislatively mandated rebates. Rebates may also be required based on specific product sales thresholds. The Company applies an estimated factor against its actual invoiced sales to represent the expected level of future discount or rebate obligations associated with the sale. At December 31, 2021 and 2020, the accrued balances related to the provision for rebates and discounts included in other current liabilities were approximately $90 million and $115 million, respectively. The Company maintains a returns policy that allows its U.S. customers to return product within a specified period prior to and subsequent to the expiration date (generally, three to six months before and 12 months after product expiration). The estimate of the provision for returns is based upon historical experience with actual returns and consideration of other relevant factors. Outside of the United States, returns are only allowed in certain countries on a limited basis. The Company’s payment terms for U.S. customers are typically 36 days from receipt of invoice. Outside of the United States, payment terms are typically 30 days to 90 days, although certain markets have longer payment terms. See Note 18 for disaggregated revenue disclosures. Cash Equivalents — Cash equivalents are comprised of certain highly liquid investments with original maturities of three months or less. Inventories — Inventories are valued at the lower of cost or net realizable value. The cost of a substantial majority of U.S. inventories is determined using the last-in, first-out (LIFO) method for both financial reporting and tax purposes. The cost of all other inventories is determined using the first-in, first-out (FIFO) method. Value Added Tax — The Company’s purchases, sales and intercompany transfers of goods are subject to value added tax (VAT) and VAT receivables are recognized for amounts that represent credits against future VAT obligations. VAT receivables included in Other current assets were $115 million and $315 million as of December 31, 2021 and 2020, respectively. VAT payables included in Accrued and other current liabilities were $9 million and $38 million as of December 31, 2021 and 2020, respectively. The related expense is included in the Company's operating expenses. Depreciation — Depreciation is provided over the estimated useful lives of the assets, principally using the straight-line method. The estimated useful lives primarily range from 25 to 40 years for buildings, and from 3 to 15 years for machinery, equipment and office furnishings. Depreciation expense was $92 million in 2021, $56 million in 2020, and $49 million in 2019. Repairs and maintenance costs are expensed as incurred as they do not extend the economic life of an asset. Advertising and Promotion Costs — Advertising and promotion costs are expensed as incurred and included in Selling, general and administrative expenses. The Company recorded advertising and promotion expenses of $236 million, $198 million, and $262 million in 2021, 2020 and 2019, respectively. Goodwill — Goodwill represents the excess of the consideration transferred over the fair value of net assets of businesses acquired. Goodwill is evaluated for impairment as of October 1 each year, or more frequently if impairment indicators exist, by first assessing qualitative factors to determine whether it is more likely than not that fair value is less than carrying value. If the Company concludes it is more likely than not that fair value is less than carrying value, a quantitative fair value test is performed. If carrying value is greater than fair value, a goodwill impairment charge will be recorded for the difference (up to the carrying value of goodwill). The Company completed the annual goodwill impairment test as of October 1, 2021 and concluded that no impairment to goodwill was necessary as the fair value of the reporting unit was significantly in excess of the carrying value. Acquired Intangibles — Acquired intangibles include products and product rights and licenses, which are initially recorded at fair value, assigned an estimated useful life, and amortized on a straight-line basis over their estimated useful lives. The Company's intangibles also include the products and product rights intangible assets attributed to Organon from Merck. The intangible assets attributable to the Company’s operations have been reflected in the consolidated financial statements based on Merck’s historical cost. Licenses include milestone payments made to collaborative partners upon or subsequent to regulatory approval. The estimated useful lives of acquired intangibles range from 5 to 15 years (see Note 10). The Company periodically evaluates whether current facts or circumstances indicate that the carrying values of its acquired intangibles may not be recoverable. If such circumstances are determined to exist, an estimate of the undiscounted future cash flows of these assets, or appropriate asset groupings, is compared to the carrying value to determine whether an impairment exists. If the asset is determined to be impaired, the loss is measured based on the difference between the carrying value of the intangible asset and its fair value, which is determined based on the net present value of estimated future cash flows. Acquired In-Process Research and Development — IPR&D that the Company acquires in conjunction with the acquisition of a business represents the fair value assigned to incomplete research projects which, at the time of acquisition, have not reached technological feasibility. The amounts are capitalized and are accounted for as indefinite-lived intangible assets, subject to impairment testing until completion or abandonment of the projects. Upon successful completion of each project, Organon will make a determination as to the then-useful life of the intangible asset, generally determined by the period in which the substantial majority of the cash flows are expected to be generated, and begin amortization. The Company evaluates IPR&D for impairment as of October 1 each year, or more frequently if impairment indicators exist, by performing a quantitative test that compares the fair value of the IPR&D intangible asset with its carrying value. If the fair value is less than the carrying amount, an impairment loss is recognized in operating results. There were no IPR&D intangible assets as of December 31, 2021 or December 31, 2020. Research and Development — Research and development costs are expensed as incurred. Research and development costs also include upfront and milestone payments related to asset acquisitions, licensing or collaborative arrangements involving clinical development programs that have not yet received regulatory approval. Foreign Currency Translation — The net assets of international operations where the local currencies have been determined to be the functional currencies are translated into U.S. dollars using current exchange rates. The U.S. dollar effects that arise from translating the net assets of these subsidiaries at changing rates are recorded in the foreign currency translation account, which is included in Accumulated other comprehensive loss and reflected as a separate component of equity. For those operations that operate in highly inflationary economies and for those operations where the U.S. dollar has been determined to be the functional currency, non-monetary foreign currency assets and liabilities are translated using historical rates, while monetary assets and liabilities are translated at current rates, with the U.S. dollar effects of rate changes included in Other (income) expense, net. Organon calculates foreign currency translation on its consolidated assets and liabilities. For periods prior to the Separation, these consolidated financial statements include Merck’s foreign currency translation for the Organon Entities. Stock-Based Compensation — Prior to the Separation, certain of the Company’s employees historically participated in Merck’s share-based compensation plans. Share-based compensation expense was either allocated to the Company based on a proportionate cost allocation method or recorded based on specific identification. Effective June 3, 2021, Organon established the 2021 Incentive Stock Plan (the "Plan"). A total of 35 million shares of Common Stock are authorized under the Plan. The plan provides for the grant of various types of awards, including restricted stock unit awards, stock appreciation rights, stock options, performance-based awards and cash awards. Under the Plan, the exercise price of awards, if any, is set on the grant date and may not be less than the fair market value per share on that date. The Company measures stock-based compensation for equity awards at fair value on the date of grant and records stock-based compensation as a charge to earnings net of the estimated impact of forfeited awards. Accordingly, the Company recognizes stock-based compensation cost only for those stock-based awards that are estimated to ultimately vest over their requisite service period, based on the vesting provisions of the individual grants. The cumulative effect on current and prior periods of a change in the estimated forfeiture rate is recognized as compensation cost in earnings in the period of the change (see Note 13). Pension and Other Postretirement Benefit Plans — Prior to the Separation, the defined benefit plans in which the Company participated related primarily to plans sponsored by Merck and for which other businesses of Merck also participate (Shared Plans). The Company accounted for the Shared Plans as multiemployer plans and therefore the related assets and liabilities were not reflected in the Consolidated Balance Sheet. For such periods prior to Separation, the Consolidated Statement of Income reflects a proportional allocation of net periodic benefit cost for the Shared Plans associated with the Company. For certain defined benefit plans attributable to the Organon Entities, the over funded or underfunded status of the plan was recognized as an asset or liability on the combined balance sheet. The Company's participation in the defined pension and postretirement benefit plans sponsored by Merck concluded upon the completion of the Separation on June 2, 2021. At Separation, Organon became the plan sponsor for certain non-U.S. defined benefit pension plans (see Note 14). Restructuring Costs — Costs associated with exit or disposal activities are recognized in the period in which they are incurred. Costs for one-time termination benefits in which the employee is required to render service until termination in order to receive the benefits are recognized ratably over the future service period. When accruing these costs, the Company recognizes the amount within a range of costs that is the best estimate within the range. When no amount within the range is a better estimate than any other amount, the Company recognizes the minimum amount within the range. Contingencies and Legal Defense Costs — The Company records accruals for contingencies and legal defense costs expected to be incurred in connection with a loss contingency when it is probable that a liability has been incurred and the amount can be reasonably estimated. Taxes on Income — Prior to the Separation, income tax expense and deferred tax balances were calculated on a separate tax return basis. The Company’s operations were included in the tax returns of certain Organon Entities, Transferring Entities or the respective Merck entities of which the Company’s business was a part. Deferred taxes are recognized for the future tax effects of temporary differences between financial and income tax reporting based on enacted tax laws and rates. The Company establishes valuation allowances for its deferred tax assets when the amount of expected future taxable income is not likely to support the use of the deduction or credit. The Company evaluates tax positions to determine whether the benefits of tax positions are more likely than not of being sustained upon audit based on the technical merits of the tax position. For tax positions that are more likely than not of being sustained upon audit, the Company recognizes the largest amount of the benefit that is greater than 50% likely of being realized upon ultimate settlement in the financial statements. For tax positions that are not more likely than not of being sustained upon audit, the Company does not recognize any portion of the benefit in the financial statements. The Company recognizes interest and penalties associated with uncertain tax positions as a component of Taxes on Income in the Consolidated Statement of Income. The Company accounts for the tax effects of the tax on global intangible low-taxed income (GILTI) of certain foreign subsidiaries in the income tax provision in the period the tax arises. The Company and Merck entered into the Tax Matters Agreement in connection with the Separation (See Note 19). Leases — The Company has operating leases primarily for real estate. The Company determines if an arrangement is a lease at inception. When evaluating contracts for embedded leases, the Company exercises judgment to determine if there is an explicit or implicit identified asset in the contract and if the Company controls the use of that asset. Embedded leases are immaterial. The lease term includes options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option. Real estate leases for facilities have a weighted average remaining lease term of 6.0 years and include one lease with an option to extend for 1 year. The Company has made an accounting policy election not to record short-term leases (leases with an initial term of 12 months or less) on the balance sheet. Lease expense associated with short term leases was not material for all periods presented. Lease expense for operating lease payments is recognized on a straight-line basis over the term of the lease. Operating lease assets and liabilities are recognized based on the present value of lease payments over the lease term. Since most of the Company’s leases do not have a readily determinable implicit discount rate, the Company uses its incremental borrowing rate to calculate the present value of lease payments. On a quarterly basis, an updated incremental borrowing rate is determined based on the weighted average remaining lease term of each asset class and the Company's pretax cost of debt for that same term. The updated rates for each asset class are applied prospectively to new leases. The Company does not separate lease components (e.g. payments for rent, real estate taxes and insurance costs) from non-lease components (e.g. common-area maintenance costs) in the event that the agreement contains both. The Company includes both the lease and non-lease components for purposes of calculating the right-of-use asset and related lease liability (if the non-lease components are fixed) (See Note 11). Use of Estimates — The presentation of these Consolidated Financial Statements and accompanying notes in conformity with U.S. GAAP require management to make estimates and assumptions that affect the amounts reported. Estimates are used in determining such items as provisions for sales discounts and returns, depreciable and amortizable lives, recoverability of inventories, amounts recorded for contingencies, environmental liabilities, pension and other postretirement benefit plan assumptions, share-based compensation assumptions, restructuring costs, impairments of long-lived assets (including intangible assets and goodwill), investments, and taxes on income. Additionally estimates are used in acquisitions, including initial fair value determinations of assets and liabilities (primarily IPR&D, other intangible assets and contingent consideration), as well as subsequent fair value measurements. For periods prior to Separation, estimates were used in determining the allocation of costs and expenses from Merck, and were used in determining such items as provisions for sales discounts and returns, depreciable and amortizable lives, recoverability of inventories, valuation of goodwill and intangibles, amounts recorded for contingencies, environmental liabilities and other reserves, pension and share-based compensation assumptions, restructuring costs, and taxes on income. Because of the uncertainty inherent in such estimates, actual results may differ from these estimates. The COVID-19 pandemic continued to negatively affect the Company's results during 2021. The assessment of certain accounting matters and specifically its effect on the Company's results require consideration of forecasted financial information in the context of the information reasonably available to the Company and the unknown future impacts of the COVID-19 pandemic at December 31, 2021 and through the date of this report. Net Investment from Merck & Co., Inc. — Net investment from Merck & Co., Inc. represented Merck’s interest in the recorded assets of the Company and the cumulative investment by Merck in the Company through the date of Separation, inclusive of operating results and the net effect of the transactions with and allocations from Merck. See Notes 2 and 19 for additional information. Recently Adopted Accounting Standards In January 2020, the Financial Accounting Standards Board ("FASB") issued new guidance intended to clarify certain interactions between accounting standards related to equity securities, equity method investments and certain derivatives. The guidance addresses accounting for the transition into and out of the equity method of accounting and measuring certain purchased options and forward contracts to acquire investments. The Company adopted the new guidance effective January 1, 2021. There was no impact to the Company’s Consolidated Financial Statements upon adoption. In December 2019, the FASB issued amended guidance on the accounting and reporting of income taxes. The guidance is intended to simplify the accounting for income taxes by removing exceptions related to certain intraperiod tax allocations and deferred tax liabilities, clarifying guidance primarily related to evaluating the step-up tax basis for goodwill in a business combination, and reflecting enacted changes in tax laws or rates in the annual effective tax rate. The Company adopted the new guidance effective January 1, 2021. There was no impact to the Company’s Consolidated Financial Statements upon adoption. Recently Issued Accounting Standards Not Yet Adopted In November 2021, the FASB issued new guidance requiring disclosures about transactions with a government that have been accounted for by analogizing to a grant or contribution accounting model. The guidance increases transparency about the types of transactions, the accounting for the transactions, and the effect of the transactions to the Company’s financial statements. The guidance is effective for the annual periods beginning in 2022 and can be applied on a prospective or retrospective basis. The Company is currently evaluating the impact of adoption on its Consolidated Financial Statements. In October 2021, the FASB issued guidance to improve the accounting for contract assets and contract liabilities from acquired revenue contracts with customers in a business combination. The guidance addresses diversity in practice and inconsistency related to the recognition of an acquired contract liability, payment terms and their effect on subsequent revenue recognized by an acquirer. The guidance is effective for the Company on January 1, 2023 and its amendments applied prospectively to business combinations occurring on or after the effective date of the guidance. Early adoption is permitted, including adoption in an interim period and subject to different transition requirements. The Company is currently evaluating the impact of adoption on its Consolidated Financial Statements. In March 2020, the FASB issued optional guidance to ease the potential burden in accounting for (or recognizing the effects of) reference rate reform on financial reporting and subsequently issued clarifying amendments. The guidance provides optional expedients and exceptions for applying GAAP to contracts, hedging relationships, and other transactions that reference the London Interbank Offered Rate ("LIBOR") or another reference rate expected to be discontinued because of reference rate reform. The optional guidance is effective upon issuance and can be applied on a prospective basis at any time between January 1, 2020 through December 31, 2022. The Company is currently evaluating the impact of adoption on its Consolidated Financial Statements.

Revenue Recognition — Recognition of revenue requires evidence of a contract, probable collection of sales proceeds and completion of substantially all performance obligations. The Company acts as the principal in its customer arrangements and therefore records revenue on a gross basis. The majority of the Company’s contracts have a single performance obligation — the promise to transfer goods. Shipping is considered immaterial in the context of the overall customer arrangement and damages or loss of goods in transit are rare. Therefore, shipping is not deemed a separately recognized performance obligation.

In the United States, sales discounts are issued to customers at the point-of-sale, through an intermediary wholesaler (known as chargebacks), or in the form of rebates. Additionally, sales are generally made with a limited right of return under certain conditions. Revenues are recorded net of provisions for sales discounts and returns, which are established at the time of sale. In addition, revenues are recorded net of time value of money discounts if collection of accounts receivable is expected to be in excess of one year.

Chargebacks are discounts that occur when a contracted customer purchases through an intermediary wholesaler. The contracted customer generally purchases product from the wholesaler at its contracted price plus a mark-up. The wholesaler, in turn, charges the Company back for the difference between the price initially paid by the wholesaler and the contract price paid to the wholesaler by the customer. The Company estimates the provision for chargebacks based on expected sell-through levels by the Company’s wholesale customers to contracted customers, as well as estimated wholesaler inventory levels. Rebates are amounts owed based upon definitive contractual agreements or legal requirements with private sector, (Managed Care), and public sector (Medicaid and Medicare Part D) benefit providers, after the final dispensing of the product by a pharmacy to a benefit plan participant. The provision for rebates is based on expected patient usage, as well as inventory levels in the distribution channel to determine the contractual obligation to the benefit providers. The Company uses historical customer segment utilization mix, sales forecasts, changes to product mix and price, inventory levels in the distribution channel, government pricing calculations and prior payment history to estimate the expected provision. The U.S. provision for aggregate customer discounts covering chargebacks and rebates was $2.0 billion in 2021, $1.8 billion in 2020, and $1.9 billion in 2019.

Amounts accrued for aggregate customer discounts are evaluated on a quarterly basis through comparison of information provided by the wholesalers, health maintenance organizations, pharmacy benefit managers, federal and state agencies, and other customers to the amounts accrued. The accrued balances relative to the provisions for chargebacks and rebates in the United States included in Accounts receivable and Accrued and other current liabilities were $54 million and $275 million, respectively, at December 31, 2021 and $41 million and $302 million, respectively, at December 31, 2020.

Outside of the United States, variable consideration in the form of discounts and rebates are a combination of commercially-driven discounts in highly competitive product classes, discounts required to gain or maintain reimbursement, or legislatively mandated rebates. Rebates may also be required based on specific product sales thresholds. The Company applies an estimated factor against its actual invoiced sales to represent the expected level of future discount or rebate obligations associated with the sale. At December 31, 2021 and 2020, the accrued balances related to the provision for rebates and discounts included in other current liabilities were approximately $90 million and $115 million, respectively.

The Company maintains a returns policy that allows its U.S. customers to return product within a specified period prior to and subsequent to the expiration date (generally, three to six months before and 12 months after product expiration). The estimate of the provision for returns is based upon historical experience with actual returns and consideration of other relevant factors. Outside of the United States, returns are only allowed in certain countries on a limited basis.

Inventories — Inventories are valued at the lower of cost or net realizable value. The cost of a substantial majority of U.S. inventories is determined using the last-in, first-out (LIFO) method for both financial reporting and tax purposes. The cost of all other inventories is determined using the first-in, first-out (FIFO) method.

Value Added Tax — The Company’s purchases, sales and intercompany transfers of goods are subject to value added tax (VAT) and VAT receivables are recognized for amounts that represent credits against future VAT obligations. VAT receivables included in Other current assets were $115 million and $315 million as of December 31, 2021 and 2020, respectively. VAT payables included in Accrued and other current liabilities were $9 million and $38 million as of December 31, 2021 and 2020, respectively. The related expense is included in the Company's operating expenses.

Depreciation — Depreciation is provided over the estimated useful lives of the assets, principally using the straight-line method. The estimated useful lives primarily range from 25 to 40 years for buildings, and from 3 to 15 years for machinery, equipment and office furnishings. Depreciation expense was $92 million in 2021, $56 million in 2020, and $49 million in 2019. Repairs and maintenance costs are expensed as incurred as they do not extend the economic life of an asset.

Goodwill — Goodwill represents the excess of the consideration transferred over the fair value of net assets of businesses acquired. Goodwill is evaluated for impairment as of October 1 each year, or more frequently if impairment indicators exist, by first assessing qualitative factors to determine whether it is more likely than not that fair value is less than carrying value. If the Company concludes it is more likely than not that fair value is less than carrying value, a quantitative fair value test is performed. If carrying value is greater than fair value, a goodwill impairment charge will be recorded for the difference (up to the carrying value of goodwill). The Company completed the annual goodwill impairment test as of October 1, 2021 and concluded that no impairment to goodwill was necessary as the fair value of the reporting unit was significantly in excess of the carrying value.

Acquired Intangibles — Acquired intangibles include products and product rights and licenses, which are initially recorded at fair value, assigned an estimated useful life, and amortized on a straight-line basis over their estimated useful lives. The Company's intangibles also include the products and product rights intangible assets attributed to Organon from Merck. The intangible assets attributable to the Company’s operations have been reflected in the consolidated financial statements based on Merck’s historical cost. Licenses include milestone payments made to collaborative partners upon or subsequent to regulatory approval. The estimated useful lives of acquired intangibles range from 5 to 15 years (see Note 10). The Company periodically evaluates whether current facts or circumstances indicate that the carrying values of its acquired intangibles may not be recoverable. If such circumstances are determined to exist, an estimate of the undiscounted future cash flows of these assets, or appropriate asset groupings, is compared to the carrying value to determine whether an impairment exists. If the asset is determined to be impaired, the loss is measured based on the difference between the carrying value of the intangible asset and its fair value, which is determined based on the net present value of estimated future cash flows.

Acquired In-Process Research and Development — IPR&D that the Company acquires in conjunction with the acquisition of a business represents the fair value assigned to incomplete research projects which, at the time of acquisition, have not reached technological feasibility. The amounts are capitalized and are accounted for as indefinite-lived intangible assets, subject to impairment testing until completion or abandonment of the projects. Upon successful completion of each project, Organon will make a determination as to the then-useful life of the intangible asset, generally determined by the period in which the substantial majority of the cash flows are expected to be generated, and begin amortization. The Company evaluates IPR&D for impairment as of October 1 each year, or more frequently if impairment indicators exist, by performing a quantitative test that compares the fair value of the IPR&D intangible asset with its carrying value. If the fair value is less than the carrying amount, an impairment loss is recognized in operating results. There were no IPR&D intangible assets as of December 31, 2021 or December 31, 2020.

Research and Development — Research and development costs are expensed as incurred. Research and development costs also include upfront and milestone payments related to asset acquisitions, licensing or collaborative arrangements involving clinical development programs that have not yet received regulatory approval.

Foreign Currency Translation — The net assets of international operations where the local currencies have been determined to be the functional currencies are translated into U.S. dollars using current exchange rates. The U.S. dollar effects that arise from translating the net assets of these subsidiaries at changing rates are recorded in the foreign currency translation account, which is included in Accumulated other comprehensive loss and reflected as a separate component of equity. For those operations that operate in highly inflationary economies and for those operations where the U.S. dollar has been determined to

Stock-Based Compensation — Prior to the Separation, certain of the Company’s employees historically participated in Merck’s share-based compensation plans. Share-based compensation expense was either allocated to the Company based on a proportionate cost allocation method or recorded based on specific identification. Effective June 3, 2021, Organon established the 2021 Incentive Stock Plan (the "Plan"). A total of 35 million shares of Common Stock are authorized under the Plan. The plan provides for the grant of various types of awards, including restricted stock unit awards, stock appreciation rights, stock options, performance-based awards and cash awards. Under the Plan, the exercise price of awards, if any, is set on the grant date and may not be less than the fair market value per share on that date. The Company measures stock-based compensation for equity awards at fair value on the date of grant and records stock-based compensation as a charge to earnings net of the estimated impact of forfeited awards. Accordingly, the Company recognizes stock-based compensation cost only for those stock-based awards that are estimated to ultimately vest over their requisite service period, based on the vesting provisions of the individual grants. The cumulative effect on current and prior periods of a change in the estimated forfeiture rate is recognized as compensation cost in earnings in the period of the change (see Note 13).

Pension and Other Postretirement Benefit Plans — Prior to the Separation, the defined benefit plans in which the Company participated related primarily to plans sponsored by Merck and for which other businesses of Merck also participate (Shared Plans). The Company accounted for the Shared Plans as multiemployer plans and therefore the related assets and liabilities were not reflected in the Consolidated Balance Sheet. For such periods prior to Separation, the Consolidated Statement of Income reflects a proportional allocation of net periodic benefit cost for the Shared Plans associated with the Company. For certain defined benefit plans attributable to the Organon Entities, the over funded or underfunded status of the plan was recognized as an asset or liability on the combined balance sheet. The Company's participation in the defined pension and postretirement benefit plans sponsored by Merck concluded upon the completion of the Separation on June 2, 2021. At Separation, Organon became the plan sponsor for certain non-U.S. defined benefit pension plans (see Note 14).

Restructuring Costs — Costs associated with exit or disposal activities are recognized in the period in which they are incurred. Costs for one-time termination benefits in which the employee is required to render service until termination in order to receive the benefits are recognized ratably over the future service period. When accruing these costs, the Company recognizes the amount within a range of costs that is the best estimate within the range. When no amount within the range is a better estimate than any other amount, the Company recognizes the minimum amount within the range.

Taxes on Income — Prior to the Separation, income tax expense and deferred tax balances were calculated on a separate tax return basis. The Company’s operations were included in the tax returns of certain Organon Entities, Transferring Entities or the respective Merck entities of which the Company’s business was a part.

Deferred taxes are recognized for the future tax effects of temporary differences between financial and income tax reporting based on enacted tax laws and rates. The Company establishes valuation allowances for its deferred tax assets when the amount of expected future taxable income is not likely to support the use of the deduction or credit.

The Company evaluates tax positions to determine whether the benefits of tax positions are more likely than not of being sustained upon audit based on the technical merits of the tax position. For tax positions that are more likely than not of being sustained upon audit, the Company recognizes the largest amount of the benefit that is greater than 50% likely of being realized upon ultimate settlement in the financial statements. For tax positions that are not more likely than not of being sustained upon audit, the Company does not recognize any portion of the benefit in the financial statements. The Company recognizes interest and penalties associated with uncertain tax positions as a component of Taxes on Income in the Consolidated Statement of Income. The Company accounts for the tax effects of the tax on global intangible low-taxed income (GILTI) of certain foreign subsidiaries in the income tax provision in the period the tax arises. The Company and Merck entered into the Tax Matters Agreement in connection with the Separation (See Note 19).

Leases — The Company has operating leases primarily for real estate. The Company determines if an arrangement is a lease at inception. When evaluating contracts for embedded leases, the Company exercises judgment to determine if there is an explicit or implicit identified asset in the contract and if the Company controls the use of that asset. Embedded leases are immaterial. The lease term includes options to extend or terminate the lease when it is reasonably certain that the Company will

exercise that option. Real estate leases for facilities have a weighted average remaining lease term of 6.0 years and include one lease with an option to extend for 1 year. The Company has made an accounting policy election not to record short-term leases (leases with an initial term of 12 months or less) on the balance sheet. Lease expense associated with short term leases was not material for all periods presented.

Lease expense for operating lease payments is recognized on a straight-line basis over the term of the lease. Operating lease assets and liabilities are recognized based on the present value of lease payments over the lease term. Since most of the Company’s leases do not have a readily determinable implicit discount rate, the Company uses its incremental borrowing rate to calculate the present value of lease payments. On a quarterly basis, an updated incremental borrowing rate is determined based on the weighted average remaining lease term of each asset class and the Company's pretax cost of debt for that same term. The updated rates for each asset class are applied prospectively to new leases. The Company does not separate lease components (e.g. payments for rent, real estate taxes and insurance costs) from non-lease components (e.g. common-area maintenance costs) in the event that the agreement contains both. The Company includes both the lease and non-lease components for purposes of calculating the right-of-use asset and related lease liability (if the non-lease components are fixed) (See Note 11).

Use of Estimates — The presentation of these Consolidated Financial Statements and accompanying notes in conformity with U.S. GAAP require management to make estimates and assumptions that affect the amounts reported. Estimates are used in determining such items as provisions for sales discounts and returns, depreciable and amortizable lives, recoverability of inventories, amounts recorded for contingencies, environmental liabilities, pension and other postretirement benefit plan assumptions, share-based compensation assumptions, restructuring costs, impairments of long-lived assets (including intangible assets and goodwill), investments, and taxes on income. Additionally estimates are used in acquisitions, including initial fair value determinations of assets and liabilities (primarily IPR&D, other intangible assets and contingent consideration), as well as subsequent fair value measurements.

For periods prior to Separation, estimates were used in determining the allocation of costs and expenses from Merck, and were used in determining such items as provisions for sales discounts and returns, depreciable and amortizable lives, recoverability of inventories, valuation of goodwill and intangibles, amounts recorded for contingencies, environmental liabilities and other reserves, pension and share-based compensation assumptions, restructuring costs, and taxes on income.

The COVID-19 pandemic continued to negatively affect the Company's results during 2021. The assessment of certain accounting matters and specifically its effect on the Company's results require consideration of forecasted financial information in the context of the information reasonably available to the Company and the unknown future impacts of the COVID-19 pandemic at December 31, 2021 and through the date of this report.

Net Investment from Merck & Co., Inc. — Net investment from Merck & Co., Inc. represented Merck’s interest in the recorded assets of the Company and the cumulative investment by Merck in the Company through the date of Separation, inclusive of operating results and the net effect of the transactions with and allocations from Merck. See Notes 2 and 19 for additional information.

In January 2020, the Financial Accounting Standards Board ("FASB") issued new guidance intended to clarify certain interactions between accounting standards related to equity securities, equity method investments and certain derivatives. The guidance addresses accounting for the transition into and out of the equity method of accounting and measuring certain purchased options and forward contracts to acquire investments. The Company adopted the new guidance effective January 1, 2021. There was no impact to the Company’s Consolidated Financial Statements upon adoption.

In December 2019, the FASB issued amended guidance on the accounting and reporting of income taxes. The guidance is intended to simplify the accounting for income taxes by removing exceptions related to certain intraperiod tax allocations and deferred tax liabilities, clarifying guidance primarily related to evaluating the step-up tax basis for goodwill in a business combination, and reflecting enacted changes in tax laws or rates in the annual effective tax rate. The Company adopted the new guidance effective January 1, 2021. There was no impact to the Company’s Consolidated Financial Statements upon adoption.

In November 2021, the FASB issued new guidance requiring disclosures about transactions with a government that have been accounted for by analogizing to a grant or contribution accounting model. The guidance increases transparency about the types of transactions, the accounting for the transactions, and the effect of the transactions to the Company’s financial statements. The guidance is effective for the annual periods beginning in 2022 and can be applied on a prospective or retrospective basis. The Company is currently evaluating the impact of adoption on its Consolidated Financial Statements.

In October 2021, the FASB issued guidance to improve the accounting for contract assets and contract liabilities from acquired revenue contracts with customers in a business combination. The guidance addresses diversity in practice and inconsistency related to the recognition of an acquired contract liability, payment terms and their effect on subsequent revenue recognized by an acquirer. The guidance is effective for the Company on January 1, 2023 and its amendments applied prospectively to business combinations occurring on or after the effective date of the guidance. Early adoption is permitted, including adoption in an interim period and subject to different transition requirements. The Company is currently evaluating the impact of adoption on its Consolidated Financial Statements.

In March 2020, the FASB issued optional guidance to ease the potential burden in accounting for (or recognizing the effects of) reference rate reform on financial reporting and subsequently issued clarifying amendments. The guidance provides optional expedients and exceptions for applying GAAP to contracts, hedging relationships, and other transactions that reference the London Interbank Offered Rate ("LIBOR") or another reference rate expected to be discontinued because of reference rate reform. The optional guidance is effective upon issuance and can be applied on a prospective basis at any time between January 1, 2020 through December 31, 2022. The Company is currently evaluating the impact of adoption on its Consolidated Financial Statements.
