Basis of Presentation	Basis of PresentationThe accompanying unaudited Condensed Consolidated Financial Statements have been prepared in accordance with U.S. generally accepted accounting principles ("GAAP") for interim financial information and with the instructions to Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements.

Principles of consolidation	In the opinion of management, all adjustments (consisting of normal recurring accruals and other adjustments) considered necessary for a fair presentation of the unaudited Condensed Consolidated Financial Statements have been included and include our accounts and the accounts of all majority-owned subsidiaries. All intercompany transactions and balances have been eliminated in consolidation.
Segment Reporting	Segment Reporting Our reporting and operating segments are as follows: •Consumer Self-Care Americas ("CSCA") comprises our consumer self-care business (OTC, infant formula, and oral care categories, and contract manufacturing) in the U.S. and Canada, including the HRA Pharma self-care business (Women's Health and Skin-Care categories) in the U.S. and Canada since it was acquired on April 29, 2022. CSCA previously included our Mexico and Brazil-based OTC businesses ("Latin American businesses") until they were disposed on March 9, 2022. •Consumer Self-Care International ("CSCI") comprises our consumer self-care business in Europe and Australia, which are primarily branded, our store brand business in the United Kingdom and parts of Europe and Asia, and includes the HRA Pharma self-care business (Women's Health, Skin-Care and Rare-Disease categories) in Europe since it was acquired on April 29, 2022.
Non U.S. Operations	Non-U.S. Operations We translate our non-U.S. dollar-denominated operations’ assets and liabilities into U.S. dollars at current rates of exchange as of the balance sheet date and income and expense items at the average exchange rate for the reporting period. Translation adjustments resulting from exchange rate fluctuations are recorded in the cumulative translation account, a component of Accumulated other comprehensive income (loss) ("AOCI"). Gains or losses from foreign currency transactions are included in Other (income) expense, net.
Allowance for Credit Losses	Allowance for Credit Losses Expected credit losses on trade receivables and contract assets are measured collectively by geographic location. The estimate of expected credit losses considers historical credit loss information that is adjusted for current conditions and for reasonable and supportable forecasts. Historical credit loss experience provides the primary basis for estimation of expected credit losses. Adjustments to historical loss information may be made for significant changes in a geographic location’s economic conditions. Receivables that do not share risk characteristics are evaluated on an individual basis. These receivables are not included in the collective evaluation. The allowance for credit losses is a valuation account that is deducted from the instruments’ cost basis to present the net amount expected to be collected. Trade receivables and contract assets are charged off against the allowance when the balance is no longer deemed collectible.

Basis of PresentationThe accompanying unaudited Condensed Consolidated Financial Statements have been prepared in accordance with U.S. generally accepted accounting principles ("GAAP") for interim financial information and with the instructions to Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. The unaudited Condensed Consolidated Financial Statements should be read in conjunction with the Consolidated Financial Statements and footnotes included in our Annual Report on Form 10-K for the year ended December 31, 2021.

Principles of consolidation

In the opinion of management, all adjustments (consisting of normal recurring accruals and other adjustments) considered necessary for a fair presentation of the unaudited Condensed Consolidated Financial Statements have been included and include our accounts and the accounts of all majority-owned subsidiaries. All intercompany transactions and balances have been eliminated in consolidation.

Segment Reporting

Our reporting and operating segments are as follows:

•Consumer Self-Care Americas ("CSCA") comprises our consumer self-care business (OTC, infant formula, and oral care categories, and contract manufacturing) in the U.S. and Canada, including the HRA Pharma self-care business (Women's Health and Skin-Care categories) in the U.S. and Canada since it was acquired on April 29, 2022.

Non U.S. Operations

Non-U.S. Operations

We translate our non-U.S. dollar-denominated operations’ assets and liabilities into U.S. dollars at current rates of exchange as of the balance sheet date and income and expense items at the average exchange rate for the

reporting period. Translation adjustments resulting from exchange rate fluctuations are recorded in the cumulative

translation account, a component of Accumulated other comprehensive income (loss) ("AOCI"). Gains or losses

from foreign currency transactions are included in Other (income) expense, net.

Allowance for Credit Losses

Expected credit losses on trade receivables and contract assets are measured collectively by geographic location. The estimate of expected credit losses considers historical credit loss information that is adjusted for current conditions and for reasonable and supportable forecasts. Historical credit loss experience provides the primary basis for estimation of expected credit losses. Adjustments to historical loss information may be made for significant changes in a geographic location’s economic conditions. Receivables that do not share risk characteristics are evaluated on an individual basis. These receivables are not included in the collective evaluation.

The allowance for credit losses is a valuation account that is deducted from the instruments’ cost basis to present the net amount expected to be collected. Trade receivables and contract assets are charged off against the allowance when the balance is no longer deemed collectible.
