SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES | SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Fiscal Year Our fiscal year ends on the Saturday closest to the last day of March. Fiscal 2018 and 2017 include 52 weeks with each quarter having 13 weeks. Fiscal 2016 includes 53 weeks with each of the first three quarters having 13 weeks and the fourth quarter having 14 weeks. Principles of Consolidation The accompanying consolidated financial statements include all accounts including those of our subsidiaries. All significant intercompany accounts and transactions have been eliminated in consolidation. Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could vary from the amounts derived from our estimates and assumptions. We consider estimates to be critical if we are required to make assumptions about material matters that are uncertain at the time of estimation or if materially different estimates could have been made or it is reasonably likely that the accounting estimate will change from period to period. The following are areas considered to be critical and require management’s judgment: revenue recognition, allowance for doubtful accounts, inventory provisions, intangible asset and goodwill valuation, legal and other judgmental accruals and income taxes. Reclassifications Certain reclassifications have been made to prior years' amounts to conform to the current year's presentation. Contingencies We may become involved in various legal proceedings that arise in the ordinary course of business, including, without limitation, patent infringement, product liability and environmental matters. Accruals recorded for various contingencies including legal proceedings, employee related litigation, self-insurance and other claims are based on judgment, the probability of losses and, where applicable, the consideration of opinions of internal and/or external legal counsel and actuarially determined estimates. When a loss is probable and a range of loss is established but a best estimate cannot be made, we record the minimum loss contingency amount, which could be zero. These estimates are often initially developed substantially earlier than the ultimate loss is known and the estimates are reevaluated each accounting period, as additional information is available. As information becomes known, an additional loss provision is recorded when either a best estimate can be made or the minimum loss amount is increased. When events result in an expectation of a more favorable outcome than previously expected, our best estimate is changed to a lower amount. Revenue Recognition Our revenue recognition policy is to recognize revenues from product sales, software and services in accordance with Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC") Topic 605, Revenue Recognition , and ASC Topic 985-605, Software . These standards require that revenues are recognized when persuasive evidence of an arrangement exists, product delivery, including customer acceptance, has occurred or services have been rendered, the price is fixed or determinable and collectability is reasonably assured. We may have multiple contracts with the same customer and each contract is typically treated as a separate arrangement. When more than one element such as equipment, disposables and services are contained in a single arrangement, we allocate revenue between the elements based on each element’s relative selling price, provided that each element meets the criteria for treatment as a separate unit of accounting. An item is considered a separate unit of accounting if it has value to the customer on a stand-alone basis. The selling price of the undelivered elements is determined by the price charged when the element is sold separately, or in cases when the item is not sold separately, by third-party evidence of selling price or by management's best estimate of selling price. For our software arrangements accounted for under the provisions of ASC 985-605, Software , we establish fair value of undelivered elements based upon vendor specific objective evidence. We offer sales rebates and discounts to certain customers. We treat sales rebates and discounts as a reduction of revenue and classify the corresponding liability as current. We estimate rebates for products where there is sufficient historical information available to predict the volume of expected future rebates. If we are unable to estimate the expected rebates reasonably, we record a liability for the maximum potential rebate or discount that could be earned. In circumstances where we provide upfront rebate payments to customers, we capitalize the rebate payments and amortize the resulting asset as a reduction of revenue using a systematic method over the life of the contract. Product Revenues Product sales consist of the sale of our disposable blood component collection and processing sets and the related equipment. On product sales to end customers, revenue is recognized when both the title and risk of loss have transferred to the customer as determined by the shipping terms and all obligations have been completed. For product sales to distributors, we recognize revenue for both equipment and disposables upon shipment of these products to our distributors. Our standard contracts with our distributors state that title to the equipment passes to the distributors at point of shipment to a distributor’s location. The distributors are responsible for shipment to the end customer along with installation, training and acceptance of the equipment by the end customer. Payments from distributors are not contingent upon resale of the product. We also place equipment at customer sites. While we retain ownership of this equipment, the customer has the right to use it for a period of time provided they meet certain agreed to conditions. We recover the cost of providing the equipment from the sale of disposables. Software Revenues We offer a variety of software solutions to support our plasma, blood collection and hospital customers. We provide information technology platforms and technical support for donor recruitment, blood and plasma testing laboratories and for efficient and compliant operations of blood and plasma collection centers. For plasma customers, we also provide information technology platforms for managing distribution of plasma from collection centers to plasma fractionation facilities. For hospitals, we provide solutions to help improve patient safety, reduce cost and ensure compliance. Our software revenues also include revenue from software sales that includes per collection or monthly subscription fees for the license and support of the software as well as hosting services. A significant portion of our software sales are perpetual licenses typically accompanied with significant implementation service fees related to software customization as well as other professional and technical service fees. We generally recognize revenue from the sale of perpetual licenses on a percentage-of-completion basis which requires us to make reasonable estimates of the extent of progress toward completion of the contract. These arrangements most often include providing customized implementation services to our customer. We also provide other services, including in some instances hosting, technical support and maintenance, for the payment of periodic, monthly, or quarterly fees. We recognize these fees and charges as earned, typically as these services are provided during the contract period. Revenue from Contracts with Customers (Topic 606) In May 2014, the Financial Accounting Standards Board (FASB) issued ASC Update No. 2014-09, Revenue from Contracts with Customers (Topic 606) . ASC Update No. 2014-09 stipulates 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 this core principle, an entity should apply the following steps: (1) identify the contract(s) with a customer; (2) identify the performance obligations in the contract; (3) determine the transaction price; (4) allocate the transaction price to the performance obligations in the contract; and (5) recognize revenue when (or as) the entity satisfies a performance obligation. ASC Update No. 2014-09 will be effective for annual reporting periods beginning after December 15, 2017, including interim periods within those reporting periods. Early adoption is permitted for annual reporting periods beginning after December 15, 2016, including interim reporting periods within that reporting period. In March 2016, the FASB issued ASC Update No. 2016-08, Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations (Reporting Revenue Gross versus Net) . The purpose of ASC Update No. 2016-08 is to clarify the guidance on principal versus agent considerations. It includes indicators that help to determine whether an entity controls the specified good or service before it is transferred to the customer and to assist in determining when the entity satisfied the performance obligation and as such, whether to recognize a gross or a net amount of consideration in their consolidated statement of operations. The effective date and transition requirements are consistent with ASC Update No. 2014-09. In April 2016, the FASB issued ASC Update No. 2016-10, Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing . The guidance clarifies that entities are not required to assess whether promised goods or services are performance obligations if they are immaterial in the context of the contract. ASC Update No. 2016-10 also addresses how to determine whether promised goods or services are separately identifiable and permits entities to make a policy election to treat shipping and handling costs as fulfillment activities. In addition, it clarifies key provisions in Topic 606 related to licensing. The effective date and transition requirements are consistent with ASC Update No. 2014-09. We have reached conclusions on our accounting assessments related to the standard and finalized updates to our accounting policies, processes and controls and will adopt the new standard on April 1, 2018 using the modified retrospective approach. We expect to record a net increase to opening retained earnings of up to $5 million upon adoption of Topic 606 in April 2018, primarily related to deferred revenue associated with software revenue. Software revenue accounts for approximately 8.6% of our total revenue. Overall, the adoption of Topic 606 is expected to have an immaterial impact on our fiscal 2019 results of operations. The timing of revenue recognition for our primary revenue stream, disposables, will not materially change. Additionally, we completed our assessment of new disclosure requirements. Upon adoption of Topic 606, we will provide additional disclosures in the notes to the consolidated financial statements, specifically related to disaggregated revenue, contract balances and performance obligations. We designed new internal controls that will be implemented in the first quarter of 2019 to address risks associated with applying the five-step model. Additionally, we established monitoring controls to identify new sales arrangements and changes in our business environment that could impact our current accounting assessment. Non-Income Taxes We are required to collect sales or valued added taxes in connection with the sale of certain of our products. We report revenues net of these amounts as they are promptly remitted to the relevant taxing authority. We are also required to pay a medical device excise tax relating to U.S. sales of Class I, II and III medical devices. This excise tax went into effect January 1, 2013, established as part of the March 2010 U.S. healthcare reform legislation and has been included in selling, general and administrative expenses. In December 2015, this tax was suspended for two years , beginning on January 1, 2016. In January 2018, another temporary two year suspension of the excise tax was passed, extending the suspension to December 31, 2019. Translation of Foreign Currencies All assets and liabilities of foreign subsidiaries are translated at the rate of exchange at year-end while sales and expenses are translated at an average rate in effect during the year. The net effect of these translation adjustments is shown in the accompanying financial statements as a component of stockholders' equity. Foreign currency transaction gains and losses, including those resulting from intercompany transactions, are charged directly to earnings and included in other expense, net on the consolidated statements of income (loss). The impact of foreign exchange on long-term intercompany loans, for which repayment has not been scheduled or planned, are recorded in accumulated other comprehensive loss on the consolidated balance sheet. Cash and Cash Equivalents Cash equivalents include various instruments such as money market funds, U.S. government obligations and commercial paper with maturities of three months or less at date of acquisition. Cash and cash equivalents are recorded at cost, which approximates fair market value. As of March 31, 2018 , our cash and cash equivalents consisted of investments in United States Government Agency and institutional money market funds. Allowance for Doubtful Accounts We establish a specific allowance for customers when it is probable that they will not be able to meet their financial obligation. Customer accounts are reviewed individually on a regular basis and appropriate reserves are established as deemed appropriate. We also maintain a general reserve using a percentage that is established based upon the age of our receivables and our collection history. We establish allowances for balances not yet due and past due accounts based on past experience. Inventories Inventories are stated at the lower of cost or market and include the cost of material, labor and manufacturing overhead. Cost is determined with the first-in, first-out method. We have based our provisions for excess, expired and obsolete inventory primarily on our estimates of forecasted net sales. Significant changes in the timing or level of demand for our products results in recording additional provisions for excess, expired and obsolete inventory. Additionally, uncertain timing of next-generation product approvals, variability in product launch strategies, non-cancelable purchase commitments, product recalls and variation in product utilization all affect our estimates related to excess, expired and obsolete inventory. Property, Plant and Equipment Property, plant and equipment is recorded at historical cost. We provide for depreciation and amortization by charges to operations using the straight-line method in amounts estimated to recover the cost of the building and improvements, equipment and furniture and fixtures over their estimated useful lives as follows: Asset Classification Estimated Useful Lives Building 30-40 Years Building improvements 5-20 Years Plant equipment and machinery 3-15 Years Office equipment and information technology 3-10 Years Haemonetics equipment 3-7 Years We evaluate the depreciation periods of property, plant and equipment to determine whether events or circumstances warrant revised estimates of useful lives. All property, plant and equipment are also tested for impairment whenever events or changes in circumstances indicate that their carrying amount may not be recoverable. Our installed base of devices includes devices owned by us and devices sold to the customer. The asset on our balance sheet classified as Haemonetics equipment consists of medical devices installed at customer sites but owned by Haemonetics. Generally the customer has the right to use it for a period of time as long as they meet the conditions we have established, which among other things, generally include one or more of the following: • Purchase and consumption of a certain level of disposable products • Payment of monthly rental fees • An asset utilization performance metric, such as performing a minimum level of procedures per month per device Consistent with the impairment tests noted below for other intangible assets subject to amortization, we review Haemonetics equipment and their related useful lives at least once a year, or more frequently if certain conditions arise, to determine if any adverse conditions exist that would indicate the carrying value of these assets may not be recoverable. To conduct these reviews we estimate the future amount and timing of demand for disposables used with these devices, from which we generate revenues. We also consider product life cycle in our evaluation of useful life and recoverability. Changes in expected demand can result in additional depreciation expense, which is classified as cost of goods sold. Any significant unanticipated changes in demand could impact the value of our devices and our reported operating results. Leasehold improvements are depreciated over the lesser of their useful lives or the term of the lease. Maintenance and repairs are generally expensed to operations as incurred. When the repair or maintenance costs significantly extend the life of the asset, these costs may be capitalized. When equipment and improvements are sold or otherwise disposed of, the asset cost and accumulated depreciation are removed from the accounts and the resulting gain or loss, if any, is included in the consolidated statements of income (loss). Goodwill and Intangible Assets Goodwill represents the excess purchase price over the fair value of the net tangible and other identifiable intangible assets acquired. Goodwill is not amortized. Instead goodwill is reviewed for impairment at least annually, or on an interim basis between annual tests when events or circumstances indicate that it is more likely than not that the fair value of a reporting unit is less than its carrying value. We perform our annual impairment test on the first day of the fiscal fourth quarter for each of our reporting units. In fiscal 2017, we early adopted ASC Update No. 2017-04, Intangibles - Goodwill and Other Topics ("Topic 350") : Simplifying the Test for Goodwill Impairment. Under this amendment, entities perform their goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. An impairment charge is recognized for the amount by which the carrying value exceeds the reporting unit's fair value. A reporting unit is defined as an operating segment or one level below an operating segment, referred to as a component. We determine our reporting units by first identifying our operating segments and then by assessing whether any components of these segments constitute a business for which discrete financial information is available and where segment management regularly reviews the operating results of that component. We aggregate components within an operating segment that have similar economic characteristics. Our reporting units for purposes of assessing goodwill impairment are organized primarily based on operating segments and geography and include: (a) North America Plasma, (b) North America Blood Center, (c) North America Hospital, (d) Europe, Middle East and Africa (collectively "EMEA"), (e) Asia-Pacific and (f) Japan. The North America Plasma reporting unit is a separate operating segment with dedicated segment management due to the size and scale of the Plasma business unit. When allocating goodwill from business combinations to our reporting units, we assign goodwill to the reporting units that we expect to benefit from the respective business combination at the time of acquisition. In addition, for purposes of performing our goodwill impairment tests, assets and liabilities, including corporate assets, which relate to a reporting unit’s operations and would be considered in determining its fair value, are allocated to the individual reporting units. We allocate assets and liabilities not directly related to a specific reporting unit, but from which the reporting unit benefits, based primarily on the respective revenue contribution of each reporting unit. We use the income approach, specifically the discounted cash flow method, to derive the fair value of each of our reporting units in preparing our goodwill impairment assessments. This approach calculates fair value by estimating the after-tax cash flows attributable to a reporting unit and then discounting these after-tax cash flows to a present value using a risk-adjusted discount rate. We selected this method as being the most meaningful in preparing our goodwill assessments because the use of the income approach typically generates a more precise measurement of fair value than the market approach. In applying the income approach to our accounting for goodwill, we make assumptions about the amount and timing of future expected cash flows, terminal value growth rates and appropriate discount rates. The amount and timing of future cash flows within our discounted cash flow analysis is based on our most recent operational budgets, long range strategic plans and other estimates. The terminal value growth rate is used to calculate the value of cash flows beyond the last projected period in our discounted cash flow analysis and reflects our best estimates for stable, perpetual growth of our reporting units. We use estimates of market-participant risk adjusted weighted average cost of capital as a basis for determining the discount rates to apply to our reporting units’ future expected cash flows. We corroborated the valuations that arose from the discounted cash flow approach by performing both a market multiple valuation and by reconciling the aggregate fair value of our reporting units to our market capitalization at the time of the test. During the fourth quarter of fiscal 2018, we performed our annual goodwill impairment test under the guidelines of ASC Update No. 2017-04. The results of the goodwill impairment test performed indicated that the estimated fair value of all of our reporting units exceeded their respective carrying values. There were no reporting units at risk of impairment as of the fiscal 2018 annual test date. During fiscal 2017, we recorded a goodwill impairment charge of $57.0 million associated with our North America Blood Center reporting unit, which represented the entire goodwill balance associated with this reporting unit. During fiscal 2016, we recorded a goodwill impairment charge of $66.3 million associated with the EMEA reporting unit. At the time the impairment assessment was performed, this represented the entire goodwill balance of this reporting unit. During fiscal 2017, management reorganized its operating segments such that certain components of the All Other operating segment became components of the EMEA operating segment. As a result, we transferred $20.5 million of goodwill to the EMEA operating segment, which represented the portion of the goodwill associated with these components. Refer to Note 9, Goodwill and Intangible Assets, for additional details regarding the goodwill impairments recorded. We review intangible assets subject to amortization for impairment at least annually or more frequently if certain conditions arise to determine if any adverse conditions exist that would indicate that the carrying value of an asset or asset group may not be recoverable, or that a change in the remaining useful life is required. Conditions indicating that an impairment exists include but are not limited to a change in the competitive landscape, internal decisions to pursue new or different technology strategies, a loss of a significant customer or a significant change in the marketplace including prices paid for our products or the size of the market for our products. When an impairment indicator exists, we test the intangible asset for recoverability. For purposes of the recoverability test, we group our amortizable intangible assets with other assets and liabilities at the lowest level of identifiable cash flows if the intangible asset does not generate cash flows independent of other assets and liabilities. If the carrying value of the intangible asset (asset group) exceeds the undiscounted cash flows expected to result from the use and eventual disposition of the intangible asset (asset group), we will write the carrying value down to the fair value in the period identified. We generally calculate fair value of our intangible assets as the present value of estimated future cash flows we expect to generate from the asset using a risk-adjusted discount rate. In determining our estimated future cash flows associated with our intangible assets, we use estimates and assumptions about future revenue contributions, cost structures and remaining useful lives of the asset (asset group). If we determine the estimate of an intangible asset's remaining useful life should be reduced based on our expected use of the asset, the remaining carrying amount of the asset is amortized prospectively over the revised estimated useful life. During fiscal 2018 we did not incur any intangible asset impairments. During fiscal 2017 and 2016 , we recorded impairment charges of $4.8 million and $25.8 million , respectively. See Note 9, Goodwill and Intangible Assets, to our consolidated financial statements contained in Item 8 for additional information. Accounting for the Costs of Computer Software to be Sold, Leased, or Otherwise Marketed ASC Topic 985-20, Software , specifies that costs incurred internally in researching and developing a computer software product should be charged to expense until technological feasibility has been established for the product. Once technological feasibility is established, all software costs should be capitalized until the product is available for general release to customers, at which point capitalized costs are amortized over their estimated useful life of five to 10 years . Technological feasibility is established when we have a detailed design of the software and when research and development activities on the underlying device, if applicable, are completed. We capitalize costs associated with both software that we sell as a separate product and software that is embedded in a device. We review the net realizable value of capitalized assets periodically to assess the recoverability of amounts capitalized. During fiscal 2017 and fiscal 2016, we recorded $4.0 million and $6.0 million , respectively, of impairment charges related to the discontinuance of certain capitalized software projects. There were no impairment charges recorded during fiscal 2018 . In the future, the net realizable value may be adversely affected by the loss of a significant customer or a significant change in the market place, which could result in an impairment being recorded. Other Current Liabilities Other current liabilities represent items payable or expected to settle within the next twelve months. The items included in the fiscal year end balances were: (In thousands) March 31, April 1, VAT liabilities $ 2,932 $ 4,051 Forward contracts 1,583 966 Deferred revenue 25,814 26,485 Accrued taxes 5,340 4,407 All other 29,991 27,741 Total $ 65,660 $ 63,650 Other Long-Term Liabilities Other long-term liabilities represent items that are not payable or expected to settle within the next twelve months. The items included in the fiscal year end balances were: (In thousands) March 31, April 1, Unfunded pension liability 14,045 14,060 Unrecognized tax benefit 2,850 1,627 Transition tax liability 7,837 — All other 9,526 6,494 Total $ 34,258 $ 22,181 Research and Development Expenses All research and development costs are expensed as incurred. Advertising Costs All advertising costs are expensed as incurred and are included in selling, general and administrative expenses in the consolidated statements of income (loss). Advertising expenses were $3.1 million , $2.5 million and $3.9 million in fiscal 2018 , 2017 and 2016 , respectively. Shipping and Handling Costs Shipping and handling costs are included in selling, general and administrative expenses. Freight is classified in cost of goods sold when the customer is charged for freight and in selling, general and administration when the customer is not explicitly charged for freight. Income Taxes The income tax provision is calculated for all jurisdictions in which we operate. The income tax provision process involves calculating current taxes due and assessing temporary differences arising from items that are taxable or deductible in different periods for tax and accounting purposes and are recorded as deferred tax assets and liabilities. Deferred tax assets are evaluated for realizability and a valuation allowance is maintained for the portion of our deferred tax assets that are not more-likely-than-not realizable. All available evidence, both positive and negative, has been considered to determine whether, based on the weight of that evidence, a valuation allowance is needed against the deferred tax assets. Significant weight has been given to our consolidated worldwide cumulative loss position for the current and prior two years. Refer to Note 5, Income Taxes for further information and discussion of our income tax provision and balances including a discussion of the impact of the Tax Cuts and Jobs Act (the "Act") enacted in December 2017. We file income tax returns in all jurisdictions in which we operate. We record a liability for uncertain tax positions taken or expected to be taken in income tax returns. Our financial statements reflect expected future tax consequences of such positions presuming the taxing authorities' full knowledge of the position and all relevant facts. We record a liability for the portion of unrecognized tax benefits claimed that we have determined are not more-likely-than-not realizable. These tax reserves have been established based on management's assessment as to the potential exposure attributable to our uncertain tax positions as well as interest and penalties attributable to these uncertain tax positions. All tax reserves are analyzed quarterly and adjustments are made as events occur that result in changes in judgment. We evaluate at the end of each reporting period whether some or all of the undistributed earnings of our foreign subsidiaries are permanently reinvested. We recognize deferred income tax liabilities to the extent that management asserts that undistributed earnings of its foreign subsidiaries are not permanently reinvested or will not be permanently reinvested in the future. Our position is based upon several factors including management’s evaluation of the Company and its subsidiaries’ financial requirements, the short term and long-term operational and fiscal objectives of the Company and the tax consequences associated with the repatriation of earnings. Derivative Instruments We account for our derivative financial instruments in accordance with ASC Topic 815, Derivatives and Hedging (“ASC 815”) and ASC Topic 820, Fair Value Measurements and Disclosures (“ASC 820”). In accordance with ASC 815, we record all derivatives on the balance sheet at fair value. The accounting for the change in the fair value of derivatives depends on the intended use of the derivative, whether we have elected to designate a derivative as a hedging instrument for accounting purposes and whether the hedging relationship has satisfied the criteria necessary to apply hedge accounting. In addition, ASC 815 provides that, for derivative instruments that qualify for hedge accounting, changes in the fair value are either (a) offset against the change in fair value of the hedged assets, liabilities, or firm commitments through earnings or (b) recognized in equity until the hedged item is recognized in earnings, depending on whether the derivative is being used to hedge changes in fair value or cash flows. The ineffective portion of a derivative’s change in fair value is immediately recognized in earnings. We do not use derivative financial instruments for trading or speculation purposes. When the underlying hedged transaction affects |
