The Company

Perrigo Company plc was incorporated under the laws of Ireland on June 28, 2013 and became the successor registrant of Perrigo Company, a Michigan corporation, on December 18, 2013 in connection with the acquisition of Elan Corporation, plc ("Elan"). Unless the context requires otherwise, the terms "Perrigo," the "Company," "we," "our," "us," and similar pronouns used herein refer to Perrigo Company plc, its subsidiaries, and all predecessors of Perrigo Company plc and its subsidiaries.

We are a leading global healthcare company, delivering value to our customers and consumers by providing Quality Affordable Healthcare Products^®. Founded in 1887 as a packager of home remedies, we have built a unique business model that is best described as the convergence of a fast-moving consumer goods company, a high-quality pharmaceutical manufacturing organization and a world-class supply chain network. We believe we are one of the world's largest manufacturers of over-the-counter (“OTC”) healthcare products and suppliers of infant formulas for the store brand market. We are a leading provider of branded OTC products throughout Europe, and also a leading producer of generic pharmaceutical topical products such as creams, lotions, gels, and nasal sprays ("extended topical") prescription drugs. We are headquartered in Ireland, and sell our products primarily in North America and Europe, as well as in other markets, including Australia, Israel and China.

Basis of Presentation

The 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, 2017. 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.

Recent Accounting Standard Pronouncements

Below are recent Accounting Standard Updates ("ASU") that we are still assessing to determine the effect on our Condensed Consolidated Financial Statements. We do not believe that any other recently issued accounting standards could have a material effect on our Condensed Consolidated Financial Statements. As new accounting pronouncements are issued, we will adopt those that are applicable under the circumstances.



Recently Issued Accounting Standards Not Yet Adopted
Standard	Description	Effective Date	Effect on the Financial Statements or Other Significant Matters
ASU 2016-02 Leases	This guidance was issued to increase transparency and comparability among organizations by requiring recognition of lease assets and lease liabilities on the balance sheet and disclosure of key information about leasing arrangements. For leases with a term of 12 months or less, lessees are permitted to make an election to not recognize right-of-use assets and lease liabilities. The guidance is required to be adopted using the modified retrospective approach. Early adoption is permitted.	January 1, 2019	We have completed our initial scoping reviews and assessment phase to identify our leasing processes and go-forward policy that will be impacted by the new standard. We are continuing the design phase of our new lease integration tool and expect our financial statement disclosures will be expanded to present additional details of our leasing arrangements. At this time, we are unable to reasonably estimate the expected increase in assets and liabilities on our Consolidated Balance Sheets or the impacts to our Consolidated Financial Statements upon adoption. We plan to adopt the amended guidance on the effective date, and we expect the right of use asset and corresponding liability will be material and require certain changes to our systems and processes.
ASU 2018-02 Income Statement - Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income	This guidance permits tax effects stranded in accumulated other comprehensive income as a result of tax reform to be reclassified to retained earnings. This reclassification is optional and will require additional disclosure regarding whether reclassification is elected or not.	January 1, 2019	We are currently evaluating the implications of adoption on our Consolidated Financial Statements.
ASU 2016-13 Measurement of Credit Losses on Financial Instruments	This guidance changes the impairment model for most financial assets and certain other instruments, replacing the current "incurred loss" approach with an "expected loss" credit impairment model, which will apply to most financial assets measured at amortized cost and certain other instruments, including trade and other receivables, loans, held-to-maturity debt securities and off-balance sheet credit exposures such as letters of credit. Early adoption is permitted.	January 1, 2020	We are currently evaluating the implications of adoption on our Consolidated Financial Statements.
ASU 2017-04 Intangibles - Goodwill and Other Simplifying the Test for Goodwill	The objective of this update is to reduce the cost and complexity of subsequent goodwill accounting by simplifying the impairment test by removing the Step 2 requirement to perform a hypothetical purchase price allocation when the carrying value of a reporting unit exceeds its fair value. If a reporting unit’s carrying value exceeds its fair value, an entity would record an impairment charge based on that difference, limited to the amount of goodwill attributed to that reporting unit. The proposal would not change the guidance on completing Step 1 of the goodwill impairment test. The proposed guidance would be applied prospectively. Early adoption is permitted.	January 1, 2020	Upon adoption, this guidance eliminates the requirement to calculate the implied fair value of goodwill to measure a goodwill impairment. After adoption, a Step 1 failure will result in an immediate impairment charge based on the carrying value of the reporting unit. We plan to adopt the standard prospectively on the effective date.
