Accounting Policies [Abstract]

Basis of Presentation

We have prepared the accompanying consolidated financial statements in accordance with accounting principles generally accepted in the United States (GAAP). In our opinion, the financial statements reflect all adjustments (including those that are normal and recurring) that are necessary for fair presentation of the results of operations for the periods shown. All intercompany balances and transactions have been eliminated.

In preparing financial statements in conformity with GAAP, we must make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue, expenses, and related disclosures at the date of the financial statements and during the reporting period. Actual results could differ from those estimates. We issued our financial statements by filing with the Securities and Exchange Commission and have evaluated subsequent events up to the time of the filing.

Revenue

We recognize revenue primarily from product sales to customers. Revenue from sales of products is recognized at the point where the customer obtains control of the goods and we satisfy our performance obligation, which is generally once the goods have shipped and the customer has assumed title. Payment terms differ by jurisdiction and customer, but payment terms in most of our major jurisdictions typically range from 30 to 120 days from date of shipment. Revenue for our product sales has not been adjusted for the effects of a financing component as we expect, at contract inception, that the period between when we transfer control of the product and when we receive payment will be one year or less. Any exceptions are either not material or we collect interest for payments made after the due date. For contract manufacturing organization (CMO) arrangements, we recognize revenue over time or at a point in time depending on our evaluation of when the customer obtains control of the promised goods or service. Revenue is recognized over time when we are creating or enhancing an asset that the customer controls. In this instance, revenue is recognized as the asset is created or enhanced or our performance does not create an asset with an alternative use and we have an enforceable right to payment for performance completed.

Provisions for rebates and discounts, as well as returns are established in the same period the related sales are recognized. We generally ship product shortly after orders are received; therefore, we generally only have a few days of orders received but not yet shipped at the end of any reporting period. Shipping and handling activities are considered to be fulfillment activities and are not considered to be a separate performance obligation. We exclude from the measurement of the transaction price all taxes assessed by a governmental authority that are imposed on our sales of product and collected from a customer.

Significant judgments must be made in determining the transaction price for sales of products related to anticipated rebates, discounts and returns. The following describe the most significant of these judgments:

Sales Rebates and Discounts - Background and Uncertainties

•Many of our products are sold to wholesale distributors. We initially invoice our customers contractual list prices. Contracts with direct and indirect customers may provide for various rebates and discounts that may differ in each contract. As a consequence, to determine the appropriate transaction price for our product sales at the time we recognize a sale to a direct customer, we must estimate any rebates or discounts that ultimately will be due to the direct customer and other customers in the distribution chain under the terms of our contracts. Judgments are required in making these estimates.

•The rebate and discount amounts are recorded as a deduction to arrive at our net product sales. We estimate these accruals using an expected value approach.

•In determining the appropriate accrual amount, we consider our historical experience with similar incentives programs and current sales data and estimates of inventory levels at our channel distributors to evaluate the impact of such programs on revenue and continually monitor the impact of this experience and adjust as necessary. Although we accrue a liability for rebates related to these programs at the time the sale is recorded, the rebate related to that sale is typically paid up to six months after the rebate or incentive period expires. Because of this time lag, in any particular period rebate adjustments may incorporate revisions of accruals for several periods.

Sales Returns - Background and Uncertainties

•We estimate a reserve for future product returns related to product sales using an expected value approach. This estimate is based on several factors, including: local returns policies and practices; returns as a percentage of revenue; an understanding of the reasons for past returns; estimated shelf life by product; and estimates of the amount of time between shipment and return. Adjustments to the returns reserve have been and may in the future be required based on revised estimates to our assumptions, which would have an impact on our consolidated results of operations. Reserves for sales returns are recorded concurrently with revenue recognition as a deduction to arrive at our net product sales and a liability.

Research and Development Expenses

Research and development expenses include the following:

•Research and development costs, which are expensed as incurred; and

•Milestone payment obligations incurred prior to regulatory approval of the product, which are accrued when the event requiring payment of the milestone occurs.

Goodwill and Intangible Assets

Goodwill and Intangible Assets

We have historically performed our annual goodwill and indefinite-lived intangible asset impairment assessment as of the last day of the fourth fiscal quarter of each year. During the fourth quarter of 2022, we elected to change the date of our annual impairment assessment from December 31st to October 1st. The change was made to more closely align the impairment assessment date with our annual planning and budgeting process as well as our long-term planning and forecasting process. We have determined that this change in accounting principle is preferable and will not affect the consolidated financial statements. Pursuant to this change in accounting principle, in 2022 we performed an impairment assessment as of the first day of our fourth fiscal quarter. The change in impairment assessment date did not delay or avoid an impairment charge. This change was not applied retrospectively as it is impracticable to do so because retrospective application would require application of significant estimates and assumptions with the use of hindsight. Accordingly, the change has been applied prospectively. See Note 12: Goodwill and Intangibles for further accounting policy information.

Advertising Expenses

Costs associated with advertising are generally expensed as incurred and are included in marketing, selling and administrative expenses in the consolidated statements of operations. The costs of TV, radio, and other electronic media and publications are expensed when the related advertising occurs. Advertising and promotion expenses totaled approximately $201 million and $248 million in 2022 and 2021, respectively. Expenses increased significantly in 2021 as compared to prior years due to the 2020 acquisition of Bayer Animal Health.

Foreign Currency Translation

Operations in our subsidiaries outside the U.S. are recorded in the functional currency of each subsidiary which is determined by a review of the environment where each subsidiary primarily generates and expends cash. The results of operations for our subsidiaries outside the U.S., where the U.S. dollar is not the functional currency, are translated from functional currencies into U.S. dollars using the weighted average currency rate for the period. Assets and liabilities are translated using the period end exchange rates. The U.S. dollar effects that arise from translating the net assets of these subsidiaries are recorded in other comprehensive income (loss).

Implementation of New Financial Accounting Pronouncements

The following table provides a brief description of an accounting standard that was effective January 1, 2022 and was adopted on that date:

Standard	Description	Effect on the financial statements or other significant matters
ASU 2021-10, Government Assistance (Topic 832)	The amendments in this update require annual disclosure of transactions with governments that are accounted for by applying a grant or contribution model. The new pronouncement requires entities to provide information about the nature, terms and conditions associated with the transactions and the financial statement line items affected.	The adoption of this guidance did not have a material impact on our consolidated financial statements.

The following table provides a brief description of an accounting standard applicable to us that has not yet been adopted:

Standard	Description	Effective Date	Effect on the financial statements or other significant matters
ASU 2020-04, Reference rate reform (Topic 848) - Facilitation of the Effects of Reference Rate Reform on Financial Reporting; ASU 2021-01, Reference Rate Reform (Topic 848): Scope; ASU 2022-06, Reference Rate Reform (Topic 848): Deferral of the Sunset Date of Topic 848	ASU 2020-04 provides optional expedients and exceptions for applying GAAP to contracts, hedging relationships, and other transactions affected by reference rate reform if certain criteria are met. ASU 2021-01 clarifies the scope of Topic 848 so that derivatives affected by the discounting transition are explicitly eligible for certain optional expedients and exceptions. ASU 2022-06 extends the period of time entities can utilize the reference rate reform relief guidance under ASU 2020-04 from December 31, 2022 to December 31, 2024.	Adoption of the guidance is optional and effective as of March 12, 2020 through December 31, 2024. Adoption is permitted at any time during the period on a prospective basis.	Our current credit facilities reference London Inter-Bank Offered Rate (LIBOR) as a benchmark rate. The underlying credit agreements include provisions which outline criteria for establishing a consistent replacement benchmark rate in the event that LIBOR is discontinued. Therefore, it is unlikely that we will need to adopt this optional guidance. However, we will continue to evaluate the impact as reference rate reform activities occur.

Income Tax

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 tax benefit from an uncertain tax position is recognized only if it is more likely than not that the tax position will be sustained on examination by the taxing authorities, based on the technical merits of the position. The tax benefits recognized in the financial statements from such a position are measured based on the largest benefit that has a greater than 50% likelihood of being realized upon ultimate resolution.
