SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES


a.	General Information

The Company

Perrigo Company plc was incorporated under the laws of Ireland on June 28, 2013. We became the successor registrant of Perrigo Company, a Michigan corporation, on December 18, 2013 in connection with the acquisition of Elan Corporation, plc ("Elan"), which is discussed further in Note 2. 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. With the acquisition of Omega Pharma Invest N.V. ("Omega"), we are an over-the-counter ("OTC") consumer goods and leading specialty pharmaceutical company, offering patients and customers high-quality products at affordable prices. From our beginning in 1887 as a packager of home remedies, we have grown to become the world's largest manufacturer of OTC healthcare products and supplier of infant formulas for the store brand market. We are also a leading provider of generic extended topical prescription products, and we receive royalties from sales of the multiple sclerosis drug Tysabri^®. We provide “Quality Affordable Healthcare Products^®” across a wide variety of product categories and geographies, primarily in North America, Europe and Australia, as well as in other markets, including Israel and China.

Basis of Presentation

Our current fiscal year is a 52 or 53 week period, which ends the Saturday on or about June 30. Fiscal years 2015, 2014, and 2013 were comprised of 52 weeks and ended on June 27, 2015, June 28, 2014, and June 29, 2013, respectively.

In fiscal year 2015, we announced that our fiscal year-end will begin on January 1 and end on December 31 of each year, starting on January 1, 2016. Fiscal year 2015, which ended on June 27, 2015, will be followed by a transition period from June 28, 2015 to December 31, 2015. We plan to disclose the results of the transition period on a Form 10-KT transition report.

Subsequent to June 27, 2015, we will continue to close our books on the Saturday closest to end of the quarter, with the last quarter ending on December 31. This practice will only affect the quarterly reporting periods and not the annual reporting periods.

Segment Reporting Change

In conjunction with the Omega acquisition, we changed our reporting segments to better align with our new organizational structure. These organizational changes were made to optimize our structure to better serve our customers and to reflect the way in which our chief operating decision maker reviews our operating results and allocates resources. The changes in our reporting segments are as follows:


•	Consumer Healthcare ("CHC"), which includes our former Consumer Healthcare segment, former Nutritionals segment, and our former Israel Pharmaceuticals and Diagnostics business, which was previously reported in our “Other” segment;


•	Branded Consumer Healthcare ("BCH"), which consists of the newly acquired Omega business;


•	Prescription Pharmaceuticals ("Rx Pharmaceuticals"), which continues to include the Rx Pharmaceuticals business;


•	Specialty Sciences, which is comprised primarily of assets focused on the treatment of multiple sclerosis(Tysabri^®).

In addition, we have an Other reporting segment that consists of our Active Pharmaceutical Ingredients ("API") business, which does not meet the quantitative threshold required to be a separately reportable segment. All historical segment information has been reclassified to conform to this new reporting segment presentation. Financial information related to our business segments and geographic locations can be found in Item 8. Note 17.

Principles of Consolidation

The consolidated financial statements include our accounts and accounts of all majority-owned subsidiaries. All intercompany transactions and balances have been eliminated in consolidation.

Unconsolidated Variable Interest Entities

We have R&D arrangements with certain biotechnology companies that we determined to be variable interest entities ("VIEs"). We did not consolidate the VIEs in our financial statements because we lack the power to direct the activities that most significantly impact their economic performance and thus are not considered the primary beneficiaries of these entities. These arrangements provide us with certain rights and obligations to purchase product candidates from the VIEs, dependent upon the outcome of the development activities.

Use of Estimates

The preparation of financial statements in conformity with U.S. generally accepted accounting principles ("GAAP") requires management to make estimates and assumptions, which affect the reported earnings, financial position and various disclosures. Although the estimates are considered reasonable, actual results could differ from the estimates.

Non-U.S. Operations

We translate our non-U.S. dollar-denominated operations’ assets and liabilities denominated in foreign currencies 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 ("AOCI"). Gains or losses from foreign currency transactions are included in Other expense, net.

b. Revenues

We generally record revenues from product sales when the goods are shipped to the customer. For customers with Free on Board ("FOB") destination terms, a provision is recorded to exclude shipments estimated to be in-transit to these customers at the end of the reporting period. A sales allowance is recorded and accounts receivable are reduced as revenues are recognized for estimated losses on credit sales due to customer claims for discounts, price discrepancies, returned goods and other items. Revenue is also reduced for any contractual customer program arrangements and related liabilities are recorded concurrently.

We maintain customer-related accruals and allowances that consist primarily of chargebacks, rebates, sales returns, shelf stock allowances, administrative fees and other incentive programs. Some of these adjustments relate specifically to the Rx Pharmaceuticals segment while others relate only to the CHC and BCH segments. Certain of these accruals and allowances are recorded in the balance sheet as current liabilities and others are recorded as a reduction in accounts receivable. Changes in these estimates and assumptions related to customer programs may result in additional accruals or allowances. Customer-related accruals and allowances were $434.9 million at June 27, 2015 and $318.0 million at June 28, 2014.

Revenues from service and royalty arrangements, including revenues from collaborative agreements, consist primarily of royalty payments, payments for research and development services, up-front fees and milestone payments. If an arrangement requires the delivery or performance of multiple deliverables or service elements, we determine whether the individual elements represent separate units of accounting. If the separate elements represent separate units of accounting, we recognize the revenue associated with each element separately and revenue is allocated among elements based on their relative selling prices. If the elements within a multiple deliverable arrangement are not considered separate units of accounting, the delivery of an individual element is considered not to have occurred if there are undelivered elements that are considered essential to the arrangement.

To the extent such arrangements contain refund clauses triggered by non-performance or other adverse circumstances, revenue is not recognized until all contractual obligations are satisfied. Non-refundable up-front fees are deferred and amortized to revenue over the related performance period. We estimate the performance period based on the specific terms of each collaborative agreement. Revenue associated with research and development services is recognized on a proportional performance basis over the period that we perform the related activities under the terms of the agreement. Revenue resulting from the achievement of contingent milestone events stipulated in the agreements is recognized when the milestone is achieved. Milestones are based upon the occurrence of a substantive element specified in the contract. Tysabri^® represented 96% of our fiscal year 2015 royalty revenue.

Shipping and handling costs billed to customers are included in net sales. Conversely, shipping and handling expenses we incur are included in cost of sales.

c. Cash and Cash Equivalents

Cash and cash equivalents consist primarily of demand deposits and other short-term investments with maturities of three months or less at the date of purchase. The carrying amount of cash and cash equivalents approximates its fair value.

d. Investments

Available for Sale Investments

We determine the appropriate classification of securities as held-to-maturity, available-for-sale, or trading. The classification depends on the purpose for which the financial assets were acquired. Marketable equity securities are classified as available-for-sale. These securities are carried at fair value with unrealized gains and losses included in AOCI. The assessment for impairment of marketable securities classified as available-for-sale is based on established financial methodologies, including quoted market prices for publicly traded securities. If we determine that a loss in the value of an investment is other than temporary, the investment is written down to its estimated fair value. Any such losses are recorded in Other expense, net. See Note 6 for more information on our available for sale investments.

Cost Method Investments

Non-marketable equity securities are carried at cost, less any write down for impairments, and are adjusted for impairment based on methodologies, an assessment of the impact of general private equity market conditions, and discounted projected future cash flows. Non-marketable equity securities are recorded in Other non-current assets on the Consolidated Balance Sheets. See Note 6 for more information on our cost method investments.

Equity Method Investments

The equity method of accounting is used for unconsolidated entities over which we have significant influence; generally this represents ownership interests of at least 20% and not more than 50%. Under the equity method of accounting, we record the investments at carrying value and adjust for a proportionate share of the profits and losses of these entities each period. We evaluate our equity method investments for recoverability. If we determine that a loss in the value of an investment is other than temporary, the investment is written down to its estimated fair value. Any such losses are recorded in Other expense, net. Evaluations of recoverability are based primarily on projected cash flows. Due to uncertainties in the estimation process, actual results could differ from such estimates. Equity method investments are recorded in Other non-current assets on the Consolidated Balance Sheets. See Note 6 for more information on our equity method investments.

e. Derivative Instruments

We record derivative instruments (including certain derivative instruments embedded in other contracts) on the balance sheet on a gross basis as either an asset or liability measured at fair value. See Note 7 for a table indicating where each component is recorded on the Consolidated Balance Sheets. Additionally, changes in a derivative's fair value, which are measured at the end of each period, is recognized in earnings unless specific hedge accounting criteria are met. If hedge accounting criteria are met for cash flow hedges, the changes in a derivative’s fair value are recorded in shareholders’ equity as a component of other comprehensive income ("OCI"), net of tax. These deferred gains and losses are recognized in income in the period in which the hedged item and hedging instrument affect earnings. Any ineffective portion of the change in fair value is immediately recognized in earnings.

We are exposed to credit loss in the event of nonperformance by the counterparties on derivative contracts. It is our policy to manage our credit risk on these transactions by dealing only with financial institutions having a long-term credit rating of "A" or better and by distributing the contracts among several financial institutions to diversify credit concentration risk. Should a counterparty default, our maximum exposure to loss is the asset balance of the instrument. The maximum term of the forward currency exchange contracts at June 27, 2015 and June 28, 2014 was 15 months.

f. Accounts Receivable and Factoring

We maintain an allowance for doubtful accounts that reduces our receivables to amounts that are expected to be collected. In estimating the allowance, management considers factors such as current overall and industry-specific economic conditions, statutory requirements, historical and anticipated customer performance, historical experience with write-offs and the level of past-due amounts. Changes in these conditions may result in additional allowances. After all attempts to collect a receivable have failed, the receivable is written off against the allowance.

As a result of the Omega acquisition, we assumed multiple accounts receivable factoring arrangements with non-related third-party financial institutions (the “Factors”). Pursuant to the terms of the arrangements, we sell to the Factors certain of our accounts receivable balances on a non-recourse basis for credit approved accounts. An administrative fee ranging from 0.14% to 0.15% per diem is charged on the gross amount of accounts receivables assigned to the Factors, plus interest is calculated at the applicable EUR LIBOR rate plus 70 basis points. The total amount factored and excluded from accounts receivable on our Consolidated Balance Sheets was $171.6 million at June 27, 2015, a $23.9 million increase since we acquired Omega.

g. Inventories

Inventories are stated at the lower of cost or market. Cost is determined using the first-in first-out ("FIFO") method. Inventory related to research and development is expensed at the point when it is determined the materials have no alternative future use.

We maintain reserves for estimated obsolete or unmarketable inventory based on the difference between the cost of the inventory and its estimated net realizable value. In estimating the reserves, management considers factors such as excess or slow-moving inventories, product expiration dating, products on quality hold, current and future customer demand and market conditions. Changes in these conditions may result in additional reserves. See Note 4 for additional information on our inventory.

h. Property, Plant and Equipment, net

Property, plant and equipment, net are recorded at cost and are depreciated using the straight-line method. Useful lives for financial reporting range from 2 to 15 years for machinery and equipment and 10 to 45 years for buildings. Maintenance and repair costs are charged to earnings, while expenditures that increase asset lives are capitalized. Depreciation expense was $84.3 million, $77.9 million, and $66.2 million for fiscal years 2015, 2014, and 2013, respectively, and includes amortization of assets recorded under capital leases.

We held the following property, plant and equipment, net at June 27, 2015 and June 28, 2014 (in millions):



	June 27, 2015			June 28, 2014
Land	$	48.7		$	36.1
Buildings	528.3			430.3
Machinery and equipment	1,094.0			1,001.4
Gross property and equipment	1,671.0			1,467.8
Less accumulated depreciation	(738.6		)	(687.9		)
Property and equipment, net	$	932.4		$	779.9

i. Goodwill and Intangible Assets

Goodwill represents amounts paid for an acquisition in excess of the fair value of net assets received. Goodwill is tested for impairment annually in our fourth quarter, or more frequently if changes in circumstances or the occurrence of events suggest impairment exists. The test for impairment requires us to make several estimates about fair value, most of which are based on projected future cash flows and market valuation multiples. The estimates associated with the goodwill impairment tests are considered critical due to the judgments required in determining fair value amounts, including projected discounted future cash flows. Changes in these estimates may result in the recognition of an impairment loss.

We have intangible assets that we have acquired through various business acquisitions and that include trademarks, trade names and brands, in-process research and development ("IPR&D"), developed product technology/formulation and product rights, distribution and license agreements, customer relationships and distribution networks, and non-compete agreements. The assets are typically initially valued using either the:

•

Relief from royalty method: This method assumes that if the acquired company did not own the intangible asset or intellectual property, it would be willing to pay a royalty for its use. The benefit of ownership of the intellectual property is valued as the relief from the royalty expense that would otherwise be incurred. We typically use this method for valuing readily transferable intangible assets that have licensing appeal, such as trade names and trademarks and certain technology assets.

•

Multi-period excess earnings method: This method starts with a forecast of the net cash flows expected to be generated by the asset over its estimated useful life. These cash flows are then adjusted to present value by applying an appropriate discount rate that reflects the risk factors associated with the cash flow streams. We typically use this method for valuing intangible assets such as developed product technology, customer relationships, product formulations and IPR&D.

Indefinite-lived intangible assets include IPR&D and certain trademarks, trade names and brands. IPR&D assets are recognized at fair value and are classified as indefinite-lived assets until the successful completion or abandonment of the associated research and development efforts. If the associated research and development is completed, the IPR&D asset becomes a definite-lived intangible asset and is amortized over the asset's assigned useful life. If it is abandoned, an impairment loss is recorded.

Indefinite-lived trademarks, trade names and brands are tested for impairment annually during our fourth quarter, or more frequently if changes in circumstances or the occurrence of events suggest impairment exists, by comparing the carrying value of the assets to their estimated fair values. An impairment loss is recognized if the carrying amount of the asset is not recoverable and its carrying amount exceeds its fair value.

Definite-lived intangible assets consist of a portfolio of developed product technology/formulation and product rights, distribution and license agreements, customer relationships, non-compete agreements, and certain trademarks and trade names. The assets are amortized on either a straight-line basis or proportionately to the benefits derived from those relationships or agreements. Useful lives vary by asset type and are determined based on the period over which the intangible asset is expected to contribute directly or indirectly to our future cash flows. We also review all other long-lived assets that have finite lives and that are not held for sale for impairment when indicators of impairment are evident by comparing the carrying value of the assets to their estimated future undiscounted cash flows.

See Note 3 for further information on our goodwill and intangible assets.

j. Debt

We elected to early adopt new accounting guidance related to deferred financing fees (as further described below under "Recent Accounting Standard Pronouncements") as of June 27, 2015. As a result, we changed our accounting policy to record deferred financing fees as a reduction of Long-term debt rather than as a Non-current asset. The balance sheet has been adjusted to reflect this change for all years presented.

k. Share-Based Awards

We measure and record compensation expense for all share-based awards based on estimated grant date fair values, and net of any estimated forfeitures over the vesting period of the awards. Forfeiture rates are estimated at the grant date based on historical experience and adjusted in subsequent periods for any differences in actual forfeitures from those estimates.

We estimate the fair value of stock option awards granted based on the Black-Scholes option pricing model, which requires the use of subjective and complex assumptions. These assumptions include estimating the expected term that awards granted are expected to be outstanding, the expected volatility of our stock price for a period commensurate with the expected term of the related options, and the risk-free rate with a maturity closest to the expected term of the related awards. Restricted stock and restricted stock units are valued based on our stock price on the day the awards are granted. See Note 10 for further information on our share-based awards.

l. Income Taxes

Deferred income tax assets and liabilities are recorded based upon the difference between the financial reporting and the tax reporting basis of assets and liabilities using the enacted tax rates. To the extent that available evidence raises doubt about the realization of a deferred income tax asset, a valuation allowance is established.

We have not made a provision for U.S. or additional non-U.S. taxes on undistributed post-acquisition earnings of non-U.S. subsidiaries because those earnings are considered permanently reinvested in the operations of those subsidiaries.

We record reserves for uncertain tax positions to the extent it is more likely than not that the tax position will be sustained on audit, based on the technical merits of the position. Periodic changes in reserves for uncertain tax positions are reflected in the provision for income taxes. We include interest and penalties attributable to uncertain tax positions and income taxes as a component of our income tax provision.

m. Legal Contingencies

We are involved in product liability, patent, commercial, regulatory and other legal proceedings that arise in the normal course of business. We record a liability when a loss is considered probable and the amount can be reasonably estimated. If the reasonable estimate of a probable loss is a range and no amount within that range is a better estimate, the minimum amount in the range is accrued. If a loss is not probable or a probable loss cannot be reasonably estimated, no liability is recorded. We have established reserves for certain of our legal matters, as described in Note 14. We also separately record any insurance recoveries that are probable of occurring.

n. Research and Development

All research and development costs, including payments related to products under development and research consulting agreements, are expensed as incurred. We may continue to make non-refundable payments to third parties for new technologies and for research and development work that has been completed. These payments may be expensed at the time of payment depending on the nature of the payment made. Research and development spending was $187.8 million, $152.5 million, and $115.2 million for fiscal years 2015, 2014, and 2013, respectively.

Fiscal year 2015 included incremental research and development expenses related to the collaboration agreement entered into as a result of the Omega acquisition. Fiscal year 2014 included incremental research and development expenses due to the Sergeant's, Velcera, and Aspen acquisitions, as well as research and development expenses related to the novel therapeutic agent for Alzheimer's disease ("ELND005") Phase 2 clinical program in collaboration with Transition Therapeutics Inc. ("Transition") that we acquired in the Elan acquisition. We ended our collaboration with Transition during the third quarter of fiscal 2014 and are no longer responsible for ongoing development activities and costs associated with ELND005. See Note 15 for additional information on collaboration agreements. Fiscal year 2013 included incremental research and development expenses attributable to the acquisitions of Sergeant's, Rosemont, and Velcera acquisitions.

We actively collaborate with other pharmaceutical companies to develop, manufacture and market certain products or groups of products. We may choose to enter into these types of agreements to, among other things, leverage our or others’ scientific research and development expertise or utilize our extensive marketing and distribution resources. Our policy on accounting for costs of strategic collaborations determines the timing of the recognition of certain development costs. In addition, this policy determines whether the cost is classified as development expense or capitalized as an asset. Management is required to form judgments with respect to the commercial status of such products in determining whether development costs meet the criteria for immediate expense or capitalization. For example, when we acquire certain products for which there is already an Abbreviated New Drug Application ("ANDA") or New Drug Application ("NDA") approval directly related to the product, and there is net realizable value based on projected sales for these products, we capitalize the amount paid as an intangible asset. If we acquire product rights that are in the development phase and as to which we have no assurance that the third-party will successfully complete its development milestones, we expense the amount paid. See Note 15 for more information on our current collaboration agreements.

o. Advertising Costs

We expense advertising costs as incurred. Advertising costs were $55.7 million, $41.4 million, and $26.1 million in fiscal years 2015, 2014, and 2013, respectively. Advertising costs relate primarily to print advertising, direct mail, on-line advertising and social media communications primarily in our CHC and BCH segments.

p. Earnings per Share ("EPS")

Basic EPS is calculated using the weighted-average number of ordinary shares outstanding during each period. It excludes both the dilutive effects of additional common shares that would have been outstanding if the shares issued under stock incentive plans had been exercised and the dilutive effect of restricted shares and restricted share units, to the extent those shares and units have not vested. Diluted EPS is calculated including the effects of shares and potential shares issued under stock incentive plans, following the treasury stock method.

q. Defined Benefit Plans

As part of the Omega acquisition in fiscal year 2015, we assumed the liabilities under a number of defined benefit plans for employees based primarily in the Netherlands, Germany, France and Norway. Omega companies operate various pension plans across each country. As part of the Elan acquisition in fiscal year 2014, we assumed responsibility for the funding of two Irish defined benefit plans, which subsequently have been combined.

Two significant assumptions, the discount rate and the expected rate of return on plan assets, are important elements of expense and liability measurement. We evaluate these assumptions annually. Other assumptions involve employee demographic factors, such as retirement patterns, mortality, turnover, and the rate of compensation increase.

The liability recognized in the balance sheet in respect of defined benefit pension plans is the present value of the defined benefit obligation at the balance sheet date less the fair value of plan assets. The defined benefit obligation is calculated periodically by independent actuaries using the projected unit credit method. The present value of the defined benefit obligation is determined by discounting the estimated future cash outflows using interest rates of high-quality corporate bonds that are denominated in the currency in which the benefits will be paid and that have terms to maturity approximating the terms of the related pension liability.

Actuarial gains and losses are recognized using the corridor method. Under the corridor method, to the extent that any cumulative unrecognized net actuarial gain or loss exceeds 10% of the greater of the present value of the defined benefit obligation and the fair value of the plan assets, that portion is recognized over the expected average remaining working lives of the plan participants. Otherwise, the net actuarial gain or loss is recorded in OCI. We recognize the funded status of benefit plans on the Consolidated Balance Sheets. In addition, we recognize the gains or losses and prior service costs or credits that arise during the period but are not recognized as components of net periodic pension cost of the period as a component of OCI. See Note 13 for further information on our defined benefit plans.

r. Recent Accounting Standard Pronouncements



Recently Adopted Accounting Standards
Accounting Standard Update	Description	Date of Adoption	Effect on the Financial Statements or Other Significant Matters
Interest- Imputation of Interest: Simplifying the Presentation of Debt Issuance Costs	These amendments require debt issuance costs related to a recognized debt liability to be presented in the balance sheet as a direct deduction from the debt liability rather than as an asset.	June 27, 2015	As of June 27, 2015 and June 28, 2014 we reclassified $40.5 million and $27.4 million, respectively, of deferred financing fees from Other non-current assets to Long-term debt.

Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists	These amendments provide guidance on the financial statement presentation of an unrecognized tax benefit when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists.	July 1, 2014	In first quarter fiscal year 2015 we presented $90.2 million as a reclassification from Non-current deferred income taxes to Other non-current liabilities upon adoption.



Recently Issued Accounting Standards Not Yet Adopted
Standard	Description	Effective Date	Effect on the Financial Statements or Other Significant Matters
Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity	These amendments raise the threshold for a disposal to qualify as a discontinued operation and require new disclosures of both discontinued operations and certain other disposals that do not currently meet the definition of a discontinued operation. Additional disclosures will include an entity's continuing involvement with a discontinued operation following the disposal date and retained equity method investments in a discontinued operation.	July 1, 2015	Adoption of this guidance will not have a material effect on our Consolidated Results of Operations or financial condition.

Revenue from Contracts with Customers	The core principle of the guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. To achieve that core principle, an entity should apply the following steps: identify the contract(s) with a customer; identify the performance obligations in the contract; determine the transaction price; allocate the transaction price to the performance obligations in the contract; and recognize revenue when (or as) the entity satisfies a performance obligation. This guidance allows for two adoption methods, full retrospective approach or modified retrospective approach.	January 1, 2018	We are currently evaluating the possible adoption methodologies and the implications of adoption on our consolidated financial statements.
