Organization, Consolidation and Presentation of Financial Statements [Abstract]

Basis of Presentation

We have prepared the accompanying consolidated and combined 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. The accounts of all wholly-owned and majority-owned subsidiaries are included in the consolidated financial statements, and all intercompany balances and transactions have been eliminated.

Certain reclassifications have been made to prior periods in the unaudited condensed consolidated and combined financial statements and accompanying notes to conform with current presentation.

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.

Consolidation

For the periods after Separation, the financial statements are prepared on a consolidated basis and reflect the results of operations, comprehensive income, financial position, equity and cash flows resulting from our operations as an independent company. For periods prior to Separation, our financial statements are combined, have been prepared on a standalone basis, and are derived from Lilly's consolidated financial statements and accounting records. The consolidated and combined financial statements reflect the financial position, results of operations and cash flows related to the animal health businesses that were transferred to Elanco Parent and are prepared in conformity with GAAP. The combined financial statements include the attribution of certain assets and liabilities that historically have been held at the Lilly corporate level but which are specifically identifiable or attributable to the businesses that have been transferred to Elanco Parent. All intercompany transactions and accounts within Elanco have been eliminated. All transactions between us and Lilly are considered to be effectively settled in the combined financial statements at the time the intercompany transaction is recorded. The total net effect of the settlement of these intercompany transactions is reflected in the combined statements of cash flows as a financing activity and in the consolidated and combined statement of equity as net parent company investment.

Expenses Related to Certain Corporate Functions

Prior to Separation, these combined financial statements include an allocation of expenses related to certain Lilly corporate functions, including executive oversight, treasury, legal, finance, human resources, tax, internal audit, financial reporting, information technology and investor relations, prior to IPO. These expenses were allocated to us based on direct usage or benefit where specifically identifiable, with the remainder allocated primarily on a pro rata basis of revenue, headcount and other measures. We consider the expenses methodology and results to be reasonable for all periods presented. However, the allocations may not be indicative of the actual expense that would have been incurred had we operated as an independent, publicly traded company for the periods presented. It is impractical to estimate what the standalone costs of Elanco would have been in the historical periods. After the Separation, a TSA between Lilly and Elanco went into effect. Under the terms of the TSA, we will be able to use these Lilly services for a fixed term established on a service-by-service basis. We are paying Lilly mutually agreed upon fees for the Lilly services provided under the TSA. Our consolidated and combined financial statements reflect the charges for Lilly services after the IPO. See Note 20: Related Party Agreements and Transactions for additional details.

Income Tax

The income tax amounts in the combined financial statements have been calculated based on a separate return methodology and presented as if our operations were separate taxpayers in the respective jurisdictions. We file income tax returns in the U.S. federal jurisdiction and various state, local and non-U.S. jurisdictions. Prior to full separation, certain of these income tax returns were filed on a consolidated or combined basis with Eli Lilly and Company and/or its subsidiaries.

Benefit and Combined Stock-Based Compensation Plans

Prior to Separation, Lilly maintained various benefit and combined stock-based compensation plans at a corporate level and other benefit plans at a country level. Our employees participated in such programs and the portion of the cost of those plans related to our employees is included in our financial statements. However, the consolidated balance sheets do not include any equity issued related to stock-based compensation plans or any net benefit plan obligations unless the benefit plan covers only our dedicated employees or where the legal obligation associated with the benefit plan transferred to Elanco. Upon Lilly's full divestiture of Elanco in March 2019, all Lilly share-based awards held by our employees were converted into awards that will be settled in Elanco shares.

Equity Balance

Prior to Separation, the equity balance in the combined financial statements represents the excess of total assets over liabilities, including intercompany balances between Elanco and Lilly (net parent company investment) and accumulated other comprehensive income (loss). Net parent company investment is primarily impacted by contributions from Lilly which are the result of treasury activities and net funding provided by or distributed to Lilly.

Revenue recognition

Revenue recognition

Effective January 1, 2018, we adopted Accounting Standards Update 2014-09, Revenue from Contracts with Customers (ASU 2014-09) and other related updates. The new standard has been applied to contracts for which performance had not been completed as of the date of adoption. Revenue presented for periods prior to 2018 was accounted for under previous standards and has not been adjusted. Revenue and net income for the years ended December 31, 2019 and 2018 do not differ materially from amounts that would have resulted from application of the previous standards.

Product Sales

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 generally is at the time we ship the product to the customer. 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 arrangements with contract manufacturing organizations (CMO), 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 and discounts, and returns. The following describe the most significant of these judgments:

Sales Rebates and Discounts - Background and Uncertainties

•Most 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 estimate 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. We record the return amounts as a deduction to arrive at our net product sales.

Research and development expenses and acquired in-process research and development

Research and development expenses include the following:

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

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

•Acquired in-process research and development (IPR&D) expense, which includes the initial costs of IPR&D projects, acquired directly in a transaction other than a business combination, that do not have an alternative future use.

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. 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, 2019 and was adopted on that date:

Standard	Description	Effect on the financial statements or other significant matters
Accounting Standards Update 2016-02, Leases	This standard was issued to increase transparency and comparability among organizations by recognizing lease assets and lease liabilities, including leases classified as operating leases under previous GAAP, on the balance sheet and requiring additional disclosures about leasing arrangements.	We adopted the standard on January 1, 2019 using the modified retrospective approach, applied at the beginning of the period of adoption, and we elected the package of transition practical expedients. Upon adoption of the standard, we recorded $84.9 million of right-of-use assets and $85.3 million of operating lease liabilities on our consolidated balance sheet. Adoption of this standard did not have a material impact on our consolidated statement of operations for the year ended December 31, 2019. See Note 13: Leases for further information.

The following table provides a brief description of the accounting standards applicable to us that have not yet been adopted:

Standard	Description	Effective Date	Effect on the financial statements or other significant matters
Accounting Standards Update 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments	This standard modifies the impairment model by requiring entities to use a forward-looking approach based on expected losses to estimate credit losses on certain types of financial instruments, including trade receivables. This may result in the earlier recognition of allowances for losses.	This standard is effective January 1, 2020, with early adoption permitted. We intend to adopt this standard on that date.	We do not expect that the adoption of this standard will have a material impact on our consolidated financial statements based on financial instruments currently held.
Accounting Standards Update 2018-15, Intangibles - Goodwill and Other Internal-Use Software (Subtopic 350-40): Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement that is a Service Contract	This guidance aligns the requirements for capitalizing implementation costs incurred in a cloud-based hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software.	This standard is effective January 1, 2020, with early adoption permitted. We intend to adopt this standard on that date.	Adoption of this standard is not expected to have a significant impact on our consolidated financial statements.
Accounting Standards Update 2019-12, Simplifying the Accounting for Income Taxes	The amendments in this update simplify the accounting for income taxes by removing certain exceptions and clarifying certain requirements regarding franchise taxes, goodwill, consolidated tax expenses, and annual effective tax rate calculations.	This standard is effective January 1, 2021, with early adoption permitted. We intend to adopt this standard on that date.	We are currently evaluating the impact of adoption of the new standard on our consolidated financial statements.
