Accounting Policies [Abstract]
Nature of Operations and Accounting Policies	Nature of Operations and Accounting Policies Nature of Operations: PerkinElmer, Inc. is a leading provider of products, services and solutions to the diagnostics, life sciences and applied markets. Through its advanced technologies and differentiated solutions, critical issues are addressed that help to improve lives and the world around us. The consolidated financial statements include the accounts of PerkinElmer, Inc. and its subsidiaries (the “Company”). All intercompany balances and transactions have been eliminated in consolidation. The Company has two operating segments: Discovery & Analytical Solutions and Diagnostics. The Company's Discovery & Analytical Solutions segment focuses on service and innovating for customers spanning the life sciences and applied markets. The Company's Diagnostics segment is targeted towards meeting the needs of clinically-oriented customers, especially within the growing areas of reproductive health, emerging market diagnostics and applied genomics. The Company's fiscal year ends on the Sunday nearest December 31. The Company reports fiscal years under a 52/53 week format and as a result, certain fiscal years will contain 53 weeks. Each of the fiscal years ended December 30, 2018 ("fiscal year 2018"), December 31, 2017 ("fiscal year 2017") and January 1, 2017 ("fiscal year 2016") included 52 weeks. The fiscal year ending December 29, 2019 will include 52 weeks. Accounting Policies and Estimates: The preparation of consolidated financial statements in accordance with United States (“U.S.”) Generally Accepted Accounting Principles (“GAAP”) requires the Company to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities. On an ongoing basis, the Company evaluates its estimates. The Company bases its estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates. Revenue Recognition: The Company enters into contracts that can include various combinations of products and services, which are generally capable of being distinct and accounted for as separate performance obligations. The Company recognizes revenue in an amount that reflects the consideration the Company expects to receive in exchange for the promised products or services when a performance obligation is satisfied by transferring control of those products or services to customers. Taxes that are collected by the Company from a customer and assessed by a governmental authority, that are both imposed on and concurrent with a specific revenue-producing transaction, are excluded from revenue. Warranty Costs: The Company provides for estimated warranty costs for products at the time of their sale. Warranty liabilities are estimated using expected future repair costs based on historical labor and material costs incurred during the warranty period. Shipping and Handling Costs: The Company reports shipping and handling revenue in revenue, to the extent they are billed to customers, and the associated costs in cost of product revenue. Inventories: Inventories, which include material, labor and manufacturing overhead, are valued at the lower of cost or market. Inventories are accounted for using the first-in, first-out method of determining inventory costs. Inventory quantities on-hand are regularly reviewed, and where necessary, provisions for excess and obsolete inventory are recorded based primarily on the Company’s estimated forecast of product demand and production requirements. Income Taxes: The Company uses the asset and liability method of accounting for income taxes. Under the asset and liability method, deferred tax assets and liabilities are recognized for the estimated future tax consequences attributable to differences between the financial statement carrying amounts of assets and liabilities and their respective tax bases. This method also requires the recognition of future tax benefits such as net operating loss carryforwards, to the extent that realization of such benefits is more likely than not. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the fiscal years in which those temporary differences are expected to be recovered or settled. A valuation allowance is established for any deferred tax asset for which realization is not more likely than not. With respect to earnings expected to be indefinitely reinvested offshore, the Company does not accrue tax for the repatriation of such foreign earnings. When the Company determines during the period that previously undistributed earnings of certain international subsidiaries no longer meet the requirements of indefinite reinvestment, the Company recognizes the income tax expense in that period. The Company provides reserves for potential payments of tax to various tax authorities related to uncertain tax positions and other issues. These reserves are based on a determination of whether and how much of a tax benefit taken by the Company in its tax filings or positions is more likely than not to be realized following resolution of any potential contingencies present related to the tax benefit. Potential interest and penalties associated with such uncertain tax positions is recorded as a component of income tax expense. See Note 8 below for additional details. The Company uses an individual unit of account approach for releasing the income tax effects of unrealized gains and losses from Accumulated Other Comprehensive Income ("AOCI"). Property, Plant and Equipment: The Company depreciates property, plant and equipment using the straight-line method over its estimated useful lives, which generally fall within the following ranges: buildings- 10 to 40 years; leasehold improvements-estimated useful life or remaining term of lease, whichever is shorter; and machinery and equipment- 3 to 8 years. Certain tooling costs are capitalized and amortized over a 3-year life, while repairs and maintenance costs are expensed. Asset Retirement Obligations: The Company records obligations associated with its lease obligations, the retirement of tangible long-lived assets and the associated asset retirement costs in accordance with authoritative guidance on asset retirement obligations. The Company reviews legal obligations associated with the retirement of long-lived assets that result from contractual obligations or the acquisition, construction, development and/or normal use of the assets. If it is determined that a legal obligation exists, regardless of whether the obligation is conditional on a future event, the fair value of the liability for an asset retirement obligation is recognized in the period in which it is incurred, if a reasonable estimate of fair value can be made. The fair value of the liability is added to the carrying amount of the associated asset, and this additional carrying amount is depreciated over the life of the asset. The difference between the gross expected future cash flow and its present value is accreted over the life of the related lease as interest expense. The amounts recorded in the consolidated financial statements are not material to any year presented. Pension and Other Postretirement Benefits: The Company sponsors both funded and unfunded U.S. and non-U.S. defined benefit pension plans and other postretirement benefits. The Company immediately recognizes actuarial gains and losses in operating results in the year in which the gains and losses occur. Actuarial gains and losses are measured annually as of the calendar month-end that is closest to the Company's fiscal year end and accordingly will be recorded in the fourth quarter, unless the Company is required to perform an interim remeasurement. The remaining components of pension expense, primarily service and interest costs and assumed return on plan assets, are recorded on a quarterly basis. The Company’s funding policy provides that payments to the U.S. pension trusts shall at least be equal to the minimum funding requirements of the Employee Retirement Income Security Act of 1974. Non-U.S. plans are accrued for, but generally not fully funded, and benefits are paid from operating funds. Translation of Foreign Currencies: For foreign operations, asset and liability accounts are translated at current exchange rates; income and expenses are translated using weighted average exchange rates for the reporting period. Resulting translation adjustments, as well as translation gains and losses from certain intercompany transactions considered permanent in nature, are reported in accumulated other comprehensive (loss) income, a separate component of stockholders’ equity. Gains and losses arising from transactions and translation of period-end balances denominated in currencies other than the functional currency are included in other expense, net. Business Combinations: Business combinations are accounted for at fair value. Acquisition costs are expensed as incurred and recorded in selling, general and administrative expenses; previously held equity interests are valued at fair value upon the acquisition of a controlling interest; in-process research and development (“IPR&D”) is recorded at fair value as an intangible asset at the acquisition date; restructuring costs associated with a business combination are expensed subsequent to the acquisition date; and changes in deferred tax asset valuation allowances and income tax uncertainties after the acquisition date affect income tax expense. Measurement period adjustments are made in the period in which the amounts are determined and the current period income effect of such adjustments will be calculated as if the adjustments had been completed as of the acquisition date. All changes that do not qualify as measurement period adjustments are also included in current period earnings. The accounting for business combinations requires estimates and judgment as to expectations for future cash flows of the acquired business, and the allocation of those cash flows to identifiable intangible assets, in determining the estimated fair value for assets acquired and liabilities assumed. The fair values assigned to tangible and intangible assets acquired and liabilities assumed, including contingent consideration, are based on management’s estimates and assumptions, as well as other information compiled by management, including valuations that utilize customary valuation procedures and techniques. If the actual results differ from the estimates and judgments used in these estimates, the amounts recorded in the financial statements could result in a possible impairment of the intangible assets and goodwill, require acceleration of the amortization expense of finite-lived intangible assets, or the recognition of additional consideration which would be expensed. Goodwill and Other Intangible Assets: The Company’s intangible assets consist of (i) goodwill, which is not being amortized; (ii) indefinite lived intangibles, which consist of a trade name that is not subject to amortization; and (iii) amortizing intangibles, which consist of patents, trade names and trademarks, licenses, customer relationships and purchased technologies, which are being amortized over their estimated useful lives. The process of testing goodwill for impairment involves the determination of the fair value of the applicable reporting units. The test consists of the comparison of the fair value to the carrying value of the reporting unit to determine if the carrying value exceeds the fair value. If the carrying value of the reporting unit exceeds its fair value, an impairment loss in an amount equal to that excess is recognized up to the amount of goodwill. This annual impairment assessment is performed by the Company on the later of January 1 or the first day of each fiscal year. Non-amortizing intangibles are also subject to an annual impairment test. The impairment test consists of a comparison of the fair value of the non-amortizing intangible asset with its carrying amount. If the carrying amount of a non-amortizing intangible asset exceeds its fair value, an impairment loss in an amount equal to that excess is recognized up to the amount of the amortizing intangible asset. In addition, the Company evaluates the remaining useful life of its non-amortizing intangible asset at least annually to determine whether events or circumstances continue to support an indefinite useful life. If events or circumstances indicate that the useful life of non-amortizing intangible asset is no longer indefinite, the asset will be tested for impairment. The intangible asset will then be amortized prospectively over its estimated remaining useful life and accounted for in the same manner as other intangible assets that are subject to amortization. Amortizing intangible assets are reviewed for impairment when indicators of impairment are present. When a potential impairment has been identified, forecasted undiscounted net cash flows of the operations to which the asset relates are compared to the current carrying value of the long-lived assets present in that operation. If such cash flows are less than such carrying amounts, long-lived assets, including such intangibles, are written down to their respective fair values. See Note 14 below for additional details. Stock-Based Compensation: The Company accounts for stock-based compensation expense based on estimated grant date fair value, generally using the Black-Scholes option-pricing model. The fair value is recognized as expense in the consolidated financial statements over the requisite service period. The determination of fair value and the timing of expense using option pricing models such as the Black-Scholes model require the input of highly subjective assumptions, including the expected term and the expected price volatility of the underlying stock. The Company estimates the expected term assumption based on historical experience. In determining the Company’s expected stock price volatility assumption, the Company reviews both the historical and implied volatility of the Company’s common stock, with implied volatility based on the implied volatility of publicly traded options on the Company’s common stock. The Company has one stock-based compensation plan from which it makes grants, which is described more fully in Note 20 below. Marketable Securities and Investments: The cost of securities sold is based on the specific identification method. If securities are classified as available for sale, the Company records these investments at their fair values with unrealized gains and losses included in accumulated other comprehensive (loss) income. Under the cost method of accounting, equity investments in private companies are carried at cost and are adjusted for other-than-temporary declines in fair value, additional investments or distributions. Cash and Cash Equivalents: The Company considers all highly liquid unrestricted instruments with a purchased maturity of three months or less to be cash equivalents. The carrying amount of cash equivalents approximates fair value due to the short maturities of these instruments. Environmental Matters: The Company accrues for costs associated with the remediation of environmental pollution when it is probable that a liability has been incurred and the Company’s proportionate share of the amount can be reasonably estimated. The recorded liabilities have not been discounted. Research and Development: Research and development costs are expensed as incurred. The fair value of acquired IPR&D costs are recorded at fair value as an intangible asset at the acquisition date and amortized once the product is ready for sale or expensed if abandoned. Restructuring Charges: In recent fiscal years, the Company has undertaken a series of restructuring actions related to the impact of acquisitions and divestitures, the alignment of its operations with its growth strategy, the integration of its business units and its productivity initiatives. In connection with these initiatives, the Company has recorded restructuring charges, as more fully described in Note 6 below. Generally, costs associated with an exit or disposal activity are recognized when the liability is incurred. Prior to recording restructuring charges for employee separation agreements, the Company notifies all employees of termination. Costs related to employee separation arrangements requiring future service beyond a specified minimum retention period are recognized over the service period. Costs related to lease terminations are recorded at the fair value of the liability based on the remaining lease rental payments, reduced by estimated sublease rentals that could be reasonably obtained for the property, at the date the Company ceases use. Comprehensive Income: Comprehensive income is defined as net income or loss and other changes in stockholders’ equity from transactions and other events from sources other than stockholders. Comprehensive income is reflected in the consolidated statements of comprehensive income. Derivative Instruments and Hedging: Derivatives are recorded on the consolidated balance sheets at fair value. Accounting for gains or losses resulting from changes in the values of those derivatives depends on the use of the derivative instrument and whether it qualifies for hedge accounting. For a cash flow hedge, the effective portion of the derivative’s gain or loss is initially reported as a component of other comprehensive income and subsequently amortized into net earnings when the hedged exposure affects net earnings. Cash flow hedges related to anticipated transactions are designated and documented at the inception of each hedge by matching the terms of the contract to the underlying transaction. The Company classifies the cash flows from hedging transactions in the same categories as the cash flows from the respective hedged items. Once established, cash flow hedges are generally recorded in other comprehensive income, unless an anticipated transaction is no longer likely to occur, and subsequently amortized into net earnings when the hedged exposure affects net earnings. Discontinued or dedesignated cash flow hedges are immediately settled with counterparties, and the related accumulated derivative gains or losses are recognized into net earnings on the consolidated financial statements. Settled cash flow hedges related to forecasted transactions that remain probable are recorded as a component of other comprehensive (loss) income and are subsequently amortized into net earnings when the hedged exposure affects net earnings. Forward contract effectiveness for cash flow hedges is calculated by comparing the fair value of the contract to the change in value of the anticipated transaction using forward rates on a monthly basis. The Company also has entered into other foreign currency forward contracts that are not designated as hedging instruments for accounting purposes. These contracts are recorded at fair value, with the changes in fair value recognized into interest and other expense, net on the consolidated financial statements. The Company also uses foreign currency denominated debt to hedge its investments in certain foreign subsidiaries. Realized and unrealized translation adjustments from these hedges are included in the foreign currency translation component of AOCI, as well as the offset translation adjustments on the underlying net assets of foreign subsidiaries. The cumulative translation gains or losses will remain in AOCI until the foreign subsidiaries are liquidated or sold. Recently Issued Accounting Pronouncements: From time to time, new accounting pronouncements are issued by the Financial Accounting Standards Board (the "FASB") and are adopted by the Company as of the specified effective dates. Unless otherwise discussed, such pronouncements did not have or will not have a significant impact on the Company’s consolidated financial position, results of operations and cash flows or do not apply to the Company’s operations. In August 2018, the FASB issued Accounting Standards Update No. 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 ("ASU 2018-15"). ASU 2018-15 aligns the accounting for implementation costs incurred in a hosting arrangement that is a service contract with the guidance on capitalizing costs associated with developing or obtaining internal-use software (and hosting arrangements that include an internal-use software license). Specifically, ASU 2018-15 amends Intangibles-Goodwill and Other (Topic 350) to include in its scope implementation costs incurred in a hosting arrangement that is a service contract and clarifies that a customer should apply Subtopic 350-40 to determine which implementation costs to capitalize as an asset related to the service contract and which costs to expense. The provisions of this guidance are to be applied either retrospectively or prospectively to all implementation costs incurred after the date of adoption. ASU 2018-15 is effective for annual reporting periods beginning after December 15, 2019, and interim periods within those years with early adoption permitted. The Company is currently evaluating the requirements of this guidance and has not yet determined the impact of its adoption on the Company's consolidated financial position, results of operations and cash flows. In August 2018, the FASB issued Accounting Standards Update No. 2018-14, Compensation - Retirement Benefits - Defined Benefit Plans - General (Subtopic 715-20): Disclosure Framework - Changes to the Disclosure Requirements for Defined Benefit Plans ("ASU 2018-14"). ASU 2018-14 adds, removes, and clarifies disclosure requirements related to defined benefit pension and other postretirement plans. ASU 2018-14 adds requirements for an entity to disclose the weighted-average interest crediting rates used in the entity’s cash balance pension plans and other similar plans; and an explanation of the reasons for significant gains and losses related to changes in the benefit obligation for the period. Further, ASU 2018-14 removes guidance that currently requires the following disclosures: the amounts in accumulated other comprehensive income expected to be recognized as part of net periodic benefit cost over the next year; the amount and timing of plan assets expected to be returned to the employer; information about (1) benefits covered by related-party insurance and annuity contracts and (2) significant transactions between the plan and related parties; and the effects of a one-percentage-point change on the assumed health care costs and the effect of this change in rates on service cost, interest cost, and the benefit obligation for postretirement health care benefits. ASU 2018-14 also clarifies the guidance in Compensation-Retirement Benefits (Topic 715-20-50-3) on defined benefit plans to require disclosure of (1) the projected benefit obligation ("PBO") and fair value of plan assets for pension plans with PBOs in excess of plan assets (the same disclosure with reference to the accumulated postretirement benefit obligation rather than the PBO is required for other postretirement benefit plans) and (2) the accumulated benefit obligation ("ABO") and fair value of plan assets for pension plans with ABOs in excess of plan assets. The provisions of this guidance are to be applied retrospectively to all periods presented upon their effective date. ASU 2018-14 is effective for annual reporting periods beginning after December 15, 2020, and interim periods within those years with early adoption permitted. The Company is currently evaluating the requirements of this guidance and has not yet determined the impact of its adoption on the Company's consolidated financial position, results of operations and cash flows. In August 2018, the FASB issued Accounting Standards Update No. 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement ("ASU 2018-13"). ASU 2018-13 adds, removes, and modifies certain disclosures related to fair value measurements. ASU 2018-13 adds requirements for an entity to disclose the changes in unrealized gains and losses for the period included in other comprehensive income for recurring Level 3 fair value measurements held at the end of the reporting period; and the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements. Further, ASU 2018-13 removes the requirement to disclose the amount of and reasons for transfers between Level 1 and Level 2 of the fair value hierarchy; the policy for timing of transfers between levels; and the valuation processes for Level 3 fair value measurements. ASU 2018-13 also modifies existing disclosure requirements related to measurement uncertainty. The amendments regarding changes in unrealized gains and losses, the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements, and the narrative description of measurement uncertainty are to be applied prospectively for only the most recent interim or annual period presented in the initial fiscal year of adoption. All other amendments are to be applied retrospectively to all periods presented upon their effective date. ASU 2018-13 is effective for annual reporting periods beginning after December 15, 2019, and interim periods within those years. Early adoption is permitted for any removed or modified disclosures. The Company is currently evaluating the requirements of this guidance and has not yet determined the impact of its adoption on the Company's consolidated financial position, results of operations and cash flows. In June 2018, the FASB issued Accounting Standards Update No. 2018-07, Compensation - Stock Compensation (Topic 718), Improvements to Nonemployee Share-Based Payment Accounting ("ASU 2018-07") which supersedes Subtopic 505-50, Equity - Equity-Based Payments to Non-employees, and expands the scope of Topic 718 (which currently only includes share-based payments to employees) to also include share-based payments issued to non-employees for goods and services, except for specific guidance on inputs to an option pricing model and the attribution of cost (that is, the period of time over which share-based payment awards vest and the pattern of cost recognition over that period). ASU 2018-07 specifies that Topic 718 applies to all share-based payment transactions in which a grantor acquires goods or services to be used or consumed in a grantor’s own operations by issuing share-based payment awards, except for financing transactions, or awards issued to customers as part of a contract accounted for under Topic 606, Revenue from Contracts with Customers ("Topic 606"). The provisions of this guidance are to be applied using a modified retrospective approach, with a cumulative-effect adjustment to retained earnings as of the beginning of the fiscal year, for all (1) liability-classified non-employee awards that have not been settled as of the adoption date and (2) equity-classified non-employee awards for which a measurement date has not been established. ASU 2018-07 is effective for annual reporting periods beginning after December 15, 2018, and interim periods within those years. Early adoption is permitted, but no earlier than a company’s adoption date of Topic 606. The Company early adopted the provisions of this guidance effective July 2, 2018. The adoption did not have a material impact on the Company's consolidated financial position, results of operations and cash flow. In March 2018, the FASB Issued Accounting Standards Update No. 2018-05, Income Taxes (Topic 740): Amendments to SEC Paragraphs Pursuant to SEC Staff Accounting Bulletin No. 118 ("ASU 2018-05"). ASU 2018-05 was issued to incorporate into Topic 740 recent SEC guidance related to the income tax accounting implications of the Tax Cut and Jobs Act (the "Tax Act"). The SEC issued Staff Accounting Bulletin No. 118 ("SAB 118") to address concerns about reporting entities’ ability to timely comply with the accounting requirements to recognize all of the effects of the Tax Act in the period of enactment. SAB 118 permits companies to disclose that some or all of the income tax effects from the Tax Act are incomplete by the due date of the financial statements, and if possible, disclose a reasonable estimate of such tax effects. ASU 2018-05 is effective immediately. The Company is applying the guidance in ASU 2018-05 when accounting for the enactment date effects of the Tax Act. At December 30, 2018, the Company completed the accounting for all of the tax effects of the Tax Act using reasonable estimates of their effects based on currently available information. These estimates may be affected as additional clarification and implementation guidance becomes available. These changes could be material to the Company's income tax expense. See Note 8 for further disclosures. In February 2018, the FASB Issued Accounting Standards Update No. 2018-03, Technical Corrections and Improvements to Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities ("ASU 2018-03"). ASU 2018-03 was issued to clarify certain aspects of guidance concerning the recognition of financial assets and liabilities established in Accounting Standards Update No. 2016-01, Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities ("ASU 2016-01"). This includes treatment for discontinuations and adjustments for equity securities without a readily determinable market value, forward contracts and purchased options, presentation requirements for certain fair value option liabilities, fair value option liabilities denominated in a foreign currency, and transition guidance for equity securities without a readily determinable fair value. ASU 2018-03 is effective for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years beginning after June 15, 2018. Early adoption is permitted for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years, as long as the Company has adopted ASU 2016-01. The Company adopted the provisions of this guidance effective July 2, 2018. The adoption did not have a material impact on the Company's consolidated financial position, results of operations and cash flows. In February 2018, the FASB Issued Accounting Standards Update No. 2018-02, Income Statement-Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income ("ASU 2018-02"). ASU 2018-02 provides entities with an option to reclassify stranded tax effects within AOCI to retained earnings in each period in which the effect of the change in the U.S. federal corporate income tax rate in the Tax Act (or portion thereof) is recorded. ASU 2018-02 requires entities to disclose a description of the accounting policy for releasing income tax effects from AOCI; whether they elect to reclassify the stranded income tax effects from the Tax Act; and information about the other income tax effects that are reclassified. ASU 2018-02 is effective for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. Early adoption is permitted, and entities should apply the proposed amendments either in the period of adoption or retrospectively to each period (or periods) in which the effect of the change in the U.S. federal corporate income tax rate in the Tax Act is recognized. The Company adopted ASU 2018-02 on December 30, 2018. The adoption of the standard resulted in an increase in retained earnings at December 30, 2018 in the amount of $6.5 million, with a corresponding decrease in AOCI. The adoption did not have a material impact on the Company's consolidated financial position, results of operations and cash flows, other than the impact discussed above. In August 2017, the FASB issued Accounting Standards Update No. 2017-12, Derivatives and Hedging (Topic 815), Targeted Improvements to Accounting for Hedging Activities ("ASU 2017-12"), which amends the hedge accounting recognition and presentation requirements in Topic 815. ASU 2017-12 makes targeted changes to the existing hedge accounting model to better align an entity’s financial reporting for hedging relationships with the entity’s risk management activities, and to reduce the complexity of, and simplify the application of, the hedge accounting model. Specifically, ASU 2017-12 expands the types of transactions eligible for hedge accounting, eliminates the requirement to separately measure and present hedge ineffectiveness, simplifies the way assessments of hedge ineffectiveness may be performed, relaxes the documentation requirements for entering into hedging positions, provides targeted improvements to fair value hedges of interest rate risk, and permits an entity to exclude the change in the fair value of cross-currency basis spreads in currency swaps from the assessment of hedge effectiveness. The standard also requires entities to provide new disclosures about the impact fair value and cash flow hedges have on their income statements and about cumulative basis adjustments arising from fair value hedges. The provisions of this guidance are to be applied using a modified retrospective approach to existing hedging relationships as of the adoption date. However, the transition provisions allow for certain elections at the date of adoption and entities may choose to apply any of the provided elections. ASU 2017-12 is effective for annual reporting periods beginning after December 15, 2018, and interim periods within those years. Early adoption is permitted, including adoption in any interim period. The Company early adopted the provisions of this guidance effective January 1, 2018. The adoption did not have a material impact on the Company's consolidated financial position, results of operations and cash flows. In May 2017, the FASB issued Accounting Standards Update No. 2017-09, Compensation - Stock Compensation (Topic 718), Scope of Modification Accounting ("ASU 2017-09"), which amends the scope of modification accounting for share-based payment arrangements. ASU 2017-09 provides guidance on the types of changes to the terms or conditions of share-based payment awards to which an entity would be required to apply modification accounting under Topic 718. Specifically, an entity would not apply modification accounting if the fair value, vesting conditions, and classification of the awards are the same immediately before and after the modification. If an entity modifies its awards and concludes that it is not required to apply modification accounting under the standard, it must still consider whether the modification affects its application of other guidance. Additionally, if a significant modification does not result in incremental compensation cost, entities are required to disclose the “lack of” incremental compensation cost resulting from such significant modification. The standard also removes the guidance in Topic 718 stating that modification accounting is not required when an entity adds an antidilution provision as long as that modification is not made in contemplation of an equity restructuring. The provisions of this guidance are to be applied on a prospective basis to awards modified on or after the effective date. ASU 2017-09 is effective for annual reporting periods beginning after December 15, 2017, and interim periods within those years. Early adoption is permitted, including adoption in any interim period. The Company adopted ASU 2017-09 effective January 1, 2018. The adoption did not have a material impact on the Company's consolidated financial position, results of operations and cash flows. In March 2017, the FASB issued Accounting Standards Update No. 2017-07, Compensation - Retirement Benefits (Topic 715), Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost ("ASU 2017-07"), which amends the requirements in Topic 715 related to the income statement presentation of the components of net periodic benefit cost for an entity’s sponsored defined benefit pension and other postretirement plans. ASU 2017-07 requires entities to (1) disaggregate the current-service-cost component from the other components of net benefit cost (the “other components”) and present it with other current employee compensation costs in their income statements and (2) present the other components elsewhere in their income statements and outside of income from operations, and disclose the income statement lines that contain the other components if they are not presented on appropriately described separate lines. Additionally, the standard requires that only the service-cost component of net benefit cost is eligible for capitalization (e.g., as part of inventory or property, plant, and equipment). The change in income statement presentation requires retrospective application, while the change in capitalized benefit cost is to be applied prospectively. ASU 2017-07 is effective for annual reporting periods beginning after December 15, 2017, and interim periods within those years, with early adoption permitted. The standard provides a practical expedient that permits entities to use the components of cost disclosed in prior years as a basis for the retrospective application of the new income statement presentation. Entities need to disclose the use of the practical expedient. The Company adopted ASU 2017-07 effective January 1, 2018 using a retrospective approach for each period presented. For the fiscal years 2017 and 2016, $(9.2) million and $11.5 million, respectively, of net periodic pension (credit) cost previously presented within operating income has been presented outside of operating income in the line item "Interest and other expense, net" in the consolidated statements of operations due to the retrospective adoption of ASU 2017-07. The adoption did not have a material impact on the Company's consolidated financial position, results of operations and cash flows, other than the impact discussed above. In January 2017, the FASB issued Accounting Standards Update No. 2017-01, Business Combinations (Topic 805), Clarifying the Definition of a Business ("ASU 2017-01"), which amends Topic 805 to provide a screen to determine when a set of assets and liabilities is not a business. The screen requires that when substantially all of the fair value of the gross assets acquired (or disposed of) is concentrated in a single identifiable asset or a group of similar identifiable assets, the set is not a business. This screen reduces the number of transactions that need to be further evaluated. If the screen is not met, the standard (1) requires that to be considered a business, a set must include, at a minimum, an input and a substantive process that together significantly contribute to the ability to create output and (2) removes the evaluation of whether a market participant could replace missing elements. The standard provides a framework to assist entities in evaluating whether both an input and a substantive process are present. The standard also provides a framework that includes two sets of criteria to consider that depend on whether a set has outputs and a more stringent criteria for sets without outputs. Lastly, the standard narrows the definition of the term "output" so that the term is consistent with how outputs are described in Topic 606, Revenue from Contracts with Customers. The provisions of this guidance are to be applied prospectively. ASU 2017-01 is effective for annual reporting periods beginning after December 15, 2017, and interim periods within those years, with early adoption permitted in limited circumstances. The Company adopted ASU 2017-01 effective January 1, 2018. The adoption did not have a material impact on the Company's consolidated financial position, results of operations and cash flows. In November 2016, the FASB issued Accounting Standards Update No. 2016-18, Statement of Cash Flows (Topic 230), Restricted Cash ("ASU 2016-18"), which amends Topic 230 to add or clarify guidance on the classification and presentation of restricted cash in the statement of cash flows. The standard requires that a statement of cash flows explain the change during the period in the total of cash, cash equivalents and amounts generally described as restricted cash or restricted cash equivalents. Therefore, amounts generally described as restricted cash and restricted cash equivalents should be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. The provisions of this guidance are to be applied using a retrospective transition method to each period presented. ASU 2016-18 is effective for annual reporting periods beginning after December 15, 2017, and interim periods within those years, with early adoption permitted. The Company adopted ASU 2016-18 effective January 1, 2018. For the fiscal years 2017 and 2016, $17.2 million and $(17.0) million, respectively, of changes in restricted cash balances that were previously presented within investing activities in the consolidated statements of cash flows have been excluded from the cash flows used in investing activities and the effect of exchange rate changes increased by $0.2 million in fiscal year 2017, due to the retrospective adoption of ASU 2016-18. Restricted cash amounting to $17.3 million and $0.2 million at January 1, 2017 and December 31, 2017, respectively, have been included with the cash and cash equivalents when reconciling the beginning of period and end of period total amounts on the consolidated statement of cash flows for the fiscal year ended December 31, 2017. Restricted cash amounting to $0.3 million and $17.3 million at January 3, 2016 and January 1, 2017, respectively, have been included with the cash and cash equivalents when reconciling the beginning of period and end of period total amounts on the consolidated statement of cash flows for the fiscal year ended January 1, 2017. The adoption did not have a material impact on the Company's consolidated financial position, results of operations and cash flows, other than the impact discussed above. In October 2016, the FASB issued Accounting Standards Update No. 2016-16, Income Taxes (Topic 740), Intra-entity Transfer of Assets Other than Inventory ("ASU 2016-16"). ASU 2016-16 removes the prohibition in Topic 740 against the immediate recognition of the current and deferred income tax effects of intra-entity transfers of assets other than inventory. The standard requires entities to recognize the income tax consequences of an intra-entity transfer of an asset other than inventory when the transfer occurs. The provisions of this guidance are to be applied on a modified retrospective basis through a cumulative-effect adjustment directly to retained earnings as of the beginning of the period of adoption. ASU 2016-16 is effective for annual reporting periods beginning after December 15, 2017, and interim periods within those years, with early adoption permitted. The Company adopted ASU 2016-16 on January 1, 2018. The adoption of the standard resulted in a decrease in the retained earnings at January 1, 2018 of approximately $2.1 million with corresponding increase in deferred tax assets of $10.7 million and decrease in prepaid taxes of $12.8 million related to prior years’ intra-entity transfers of assets other than inventory. The adoption did not have a material impact on the Company's consolidated financial position, results of operations and cash flows, other than the impact discussed above. In August 2016, the FASB issued Accounting Standards Update No. 2016-15, Statement of Cash Flows (Topic 230), Classification of Certain Cash Receipts and Cash Payments ("ASU 2016-15"). ASU 2016-15 addresses eight specific cash flow issues with the objective of reducing the existing diversity in practice in how certain cash receipts and cash payments are presented and classified in the statement of cash flows under Topic 230 and other topics. The provisions of this guidance are to be applied using a retrospective transition method to each period presented, and if it is impracticable to apply the amendments retrospectively for some of the issues, ASU 2016-15 allows the amendments for those issues to be applied prospectively as of the earliest date practicable. ASU 2016-15 is effective for annual reporting periods beginning after December 15, 2017, and interim periods within those years, with early adoption permitted. The Company adopted ASU 2016-15 effective January 1, 2018. The adoption did not have a material impact on the Company's consolidated financial position, results of operations and cash flows. In June 2016, the FASB issued Accounting Standards Update No. 2016-13, Financial Instruments - Credit Losses (Topic 326), Measurement of Credit Losses on Financial Instruments ("ASU 2016-13"). ASU 2016-13 changes how entities will measure credit losses for most financial assets and certain other instruments that are not measured at fair value through net income. The standard requires entities to use the expected loss impairment model and 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, net investments in leases and off-balance sheet credit exposures. Entities are required to estimate the lifetime “expected credit loss” for each applicable financial asset and record an allowance that, when deducted from the amortized cost basis of the financial asset, presents the net amount expected to be collected on the financial asset. The standard also amends the impairment model for available-for-sale (“AFS”) debt securities and requires entities to determine whether all or a portion of the unrealized loss on an AFS debt security is a credit loss. An entity will recognize an allowance for credit losses on an AFS debt security as a contra-account to the amortized cost basis rather than as a direct reduction of the amortized cost basis of the investment. The provisions of this guidance are to be applied using a modified-retrospective approach. A prospective transition approach is required for debt securities for which an other-than-temporary impairment had been recognized before the effective date. ASU 2016-13 is effective for annual reporting periods beginning after December 15, 2019, and interim periods within those years. Early adoption is permitted for annual periods beginning after December 15, 2018, and interim periods therein. The Company is currently evaluating the requirements of this guidance and has not yet determined the impact of its adoption on the Company's consolidated financial position, results of operations and cash flows. In February 2016, the FASB issued Accounting Standards Update No. 2016-02, Leases ("ASU 2016-02"). ASU 2016-02 requires organizations that lease assets to recognize assets and liabilities on the balance sheet related to the rights and obligations created by those leases, regardless of whether they are classified as finance or operating leases. Consistent with current guidance, the recognition, measurement, and presentation of expenses and cash flows arising from a lease of assets will primarily depend on its classification as a finance or operating lease. ASU 2016-02 also requires new disclosures to help financial statement users better understand the amount, timing, and uncertainty of cash flows arising from leases. The provisions of this guidance are effective for annual periods beginning after December 15, 2018, and interim periods within those years, with early adoption permitted. ASU 2016-02 is to be applied using a modified retrospective approach. Subsequent to the issuance of ASU 2016-02, in July 2018, the FASB issued Accounting Standards Update No. 2018-10, Codification Improvements to Topic 842, Leases ("ASU 2018-10") and Accounting Standards Update No. 2018-11, Leases (Topic 842): Targeted Improvements ("ASU 2018-11"). The amendments in ASU 2018-10 clarify, correct or remove inconsistencies in the guidance provided under ASU 2016-02 related to sixteen specific issues identified. The amendments in ASU 2018-11 provide entities with an additional (and optional) transition method to adopt the new leases standard. Under the new transition method, an entity initially applies the new leases standard at the adoption date and recognizes a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption. Consequently, an entity's reporting for the comparative periods presented in the financial statements in the period of adoption will continue to be in accordance with ASC 840, Leases ("ASC 840"). An entity that elects this additional (and optional) transition method must provide the required disclosures under ASC 840 for all periods that continue to be in accordance with ASC 840. ASU 2018-11 also provides lessors with a practical expedient, by class of underlying asset, to not separate nonlease components from the associated lease component and, instead, to account for those components as a single component if certain criteria are met. The effective date and transition requirements for these two standards are the same as the effective date and transition requirements of ASU 2016-02. The standards were effective for the Company beginning on December 31, 2018. The Company did not early adopt these standards and adopted these standards using the optional transition method. The Company elected to apply the modified retrospective approach, and applied the new leases standard at December 31, 2018, with a cumulative effect adjustment recognized in the opening balance of retained earnings in fiscal year 2019. As a lessee, the most significant impact of the standards relates to the recognition of the right-of-use assets and lease liabilities for the operating leases in the balance sheet. In addition, the Company had deferred gains from a sale-leaseback transaction that are being amortized in operating expenses over the lease term and the lease is accounted for as an operating lease under ASC 840. Under the new standards, the Company will recognize the deferred gains from the sale as a cumulative-effect adjustment in retained earnings at December 31, 2018. The Company will also derecognize the impact of its build-to-suit arrangement in which the Company was the deemed owner during the construction period, for which the construction is complete and the lease commenced before the initial date of adoption. The adoption of the standards will result in an increase in retained earnings at December 31, 2018 of approximately $19.1 million for the cumulative effect of initially applying the standards as of that date. In addition, the adoption of the standards will result in recognition of right-of-use assets of approximately $190.7 million and lease liabilities of approximately $137.7 million, primarily related to the facilities operating leases, a decrease in property and equipment of approximately $31.9 million and an increase in deferred tax liabilities of $2.1 million for the tax impact of the cumulative adjustments. The adoption will have no impact to cash from or used in operating, investing or financing activities in the Company's consolidated statement of cash flows at December 31, 2018. In May 2014, the FASB issued Accounting Standards Update No. 2014-09, Revenue from Contracts with Customers ("ASU 2014-09"). Under this new guidance, an entity should use a five-step process to recognize revenue, depicting 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. The standard also requires new disclosures regarding the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. Subsequent to the issuance of the standard, the FASB decided to defer the effective date for one year to annual reporting periods beginning after December 15, 2017, with early adoption permitted for annual reporting periods beginning after December 15, 2016. In November 2017, the FASB also issued Accounting Standards Update No. 2017-14, Income Statement-Reporting Comprehensive Income (Topic 220), Revenue Recognition (Topic 605), and Revenue from Contracts with Customers (Topic 606). ASU 2017-14 includes amendments to certain SEC paragraphs within the FASB Accounting Standards Codification ("Codification"). ASU 2017-14 amends the Codification to incorporate SEC Staff Accounting Bulletin No. 116 and SEC Interpretive Release on Vaccines for Federal Government Stockpiles (SEC Release No. 33-10403) to align existing SEC staff guidance with Revenue from Contracts with Customers (Topic 606). In May 2016, the FASB also issued Accounting Standards Update No. 2016-12, Revenue from Contracts with Customers (Topic 606), Narrow-Scope Improvements and Practical Expedients ("ASU 2016-12"), which amended its revenue recognition guidance in ASU 2014-09 on transition, collectability, non-cash consideration, contract modifications and completed contracts at transition and the presentation of sales and other similar taxes collected from customers. In April 2016, the FASB also issued Accounting Standards Update No. 2016-10, Revenue from Contracts with Customers (Topic 606), Identifying Performance Obligations and Licensing ("ASU 2016-10"), which amended its revenue recognition guidance in ASU 2014-09 on identifying performance obligations to allow entities to disregard items that are immaterial in the context of the contract, clarify when a promised good or service is separately identifiable (i.e., distinct within the context of the contract) and allow an entity to elect to account for the cost of shipping and handling performed after control of a good has been transferred to the customer as a fulfillment cost (i.e., an expense). ASU 2016-10 also clarifies how an entity should evaluate the nature of its promise in granting a license of intellectual property ("IP") and requires entities to classify IP in one of two categories: functional IP or symbolic IP, which will determine whether it recognizes revenue over time or at a point in time. ASU 2016-10 also address how entities should consider license renewals and restrictions and apply the exception for sales- and usage-based royalties received in exchange for licenses of IP. In March 2016, the FASB also issued Accounting Standards Update No. 2016-08, Revenue from Contracts with Customers (Topic 606), Principal versus Agent Considerations (Reporting Revenue Gross versus Net) ("ASU 2016-08"), which amended the principal-versus-agent implementation guidance and illustrations in ASU 2014-09. ASU 2016-08 clarifies that an entity should evaluate when it is the principal or agent for each specified good or service promised in a contract with a customer. ASU 2017-14, ASU 2016-12, ASU 2016-10, ASU 2016-08 and ASU 2014-09 may be adopted either using a full retrospective approach or a modified retrospective approach. The standards were effective for the Company beginning on January 1, 2018. The Company did not early adopt these standards and adopted these standards using the modified retrospective approach. The most significant impact of the standards relates to the accounting for certain transactions with multiple elements or “bundled” arrangements. Specifically, for sales of software subscriptions or sales of licenses and maintenance, the Company will recognize the license revenue predominantly at the time of billing and delivery rather than recognizing the entire sales price ratably over the maintenance period, which is the Company's previous practice. In addition, for certain sales of instruments that include customer-specified acceptance criteria, the Company will recognize revenue when the customer obtains control of the instrument which is typically upon delivery or when title has transferred to the customer, as the Company believes acceptance is perfunctory. The Company will also capitalize incremental commission fees as a result of obtaining contracts when these fees are recoverable and will amortize the assets based on the transfer of goods or services to which the assets relate which typically range from two to six years. The Company elected to apply the modified retrospective approach only to contracts not completed as of January 1, 2018. The adoption of the standards resulted in an increase in the retained earnings at January 1, 2018 of approximately $10.2 million for the cumulative effect of initially applying the standards at January 1, 2018. In addition, the adoption of the standards resulted primarily in a reduction in deferred revenue of approximately $11.5 million, mainly driven by the upfront recognition of license revenue and certain multi-year software subscriptions, and an increase in deferred tax liability of approximately $3.0 million for the tax impact of the cumulative adjustments. The cumulative effect of recognizing instrument sales upon delivery or transfer of title and capitalizing the incremental commission fees were not material at January 1, 2018. The adoption of the standards had no impact to cash from or used in operating, investing, or financing activities in the Company's consolidated statement of cash flows at January 1, 2018. Refer to Note 3, Changes in Accounting Policies, for the impact of adoption of the standards on the Company's consolidated financial statements for the fiscal year ended December 30, 2018. Also refer to Note 2, Revenue, for the disclosures required by the standards.

Nature of Operations and Accounting Policies

Nature of Operations: PerkinElmer, Inc. is a leading provider of products, services and solutions to the diagnostics, life sciences and applied markets. Through its advanced technologies and differentiated solutions, critical issues are addressed that help to improve lives and the world around us.

The consolidated financial statements include the accounts of PerkinElmer, Inc. and its subsidiaries (the “Company”). All intercompany balances and transactions have been eliminated in consolidation.

The Company has two operating segments: Discovery & Analytical Solutions and Diagnostics. The Company's Discovery & Analytical Solutions segment focuses on service and innovating for customers spanning the life sciences and applied markets. The Company's Diagnostics segment is targeted towards meeting the needs of clinically-oriented customers, especially within the growing areas of reproductive health, emerging market diagnostics and applied genomics.

The Company's fiscal year ends on the Sunday nearest December 31. The Company reports fiscal years under a 52/53 week format and as a result, certain fiscal years will contain 53 weeks. Each of the fiscal years ended December 30, 2018 ("fiscal year 2018"), December 31, 2017 ("fiscal year 2017") and January 1, 2017 ("fiscal year 2016") included 52 weeks. The fiscal year ending December 29, 2019 will include 52 weeks.

Accounting Policies and Estimates: The preparation of consolidated financial statements in accordance with United States (“U.S.”) Generally Accepted Accounting Principles (“GAAP”) requires the Company to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities. On an ongoing basis, the Company evaluates its estimates. The Company bases its estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates.

Revenue Recognition: The Company enters into contracts that can include various combinations of products and services, which are generally capable of being distinct and accounted for as separate performance obligations. The Company recognizes revenue in an amount that reflects the consideration the Company expects to receive in exchange for the promised products or services when a performance obligation is satisfied by transferring control of those products or services to customers.

Taxes that are collected by the Company from a customer and assessed by a governmental authority, that are both imposed on and concurrent with a specific revenue-producing transaction, are excluded from revenue.

Warranty Costs: The Company provides for estimated warranty costs for products at the time of their sale. Warranty liabilities are estimated using expected future repair costs based on historical labor and material costs incurred during the warranty period.

Shipping and Handling Costs: The Company reports shipping and handling revenue in revenue, to the extent they are billed to customers, and the associated costs in cost of product revenue.

Inventories: Inventories, which include material, labor and manufacturing overhead, are valued at the lower of cost or market. Inventories are accounted for using the first-in, first-out method of determining inventory costs. Inventory quantities on-hand are regularly reviewed, and where necessary, provisions for excess and obsolete inventory are recorded based primarily on the Company’s estimated forecast of product demand and production requirements.

Income Taxes: The Company uses the asset and liability method of accounting for income taxes. Under the asset and liability method, deferred tax assets and liabilities are recognized for the estimated future tax consequences attributable to differences between the financial statement carrying amounts of assets and liabilities and their respective tax bases. This method also requires the recognition of future tax benefits such as net operating loss carryforwards, to the extent that realization of such benefits is more likely than not. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the fiscal years in which those temporary differences are expected to be recovered or settled. A valuation allowance is established for any deferred tax asset for which realization is not more likely than not. With respect to earnings expected to be indefinitely reinvested offshore, the Company does not accrue tax for the repatriation of such foreign earnings. When the Company determines during the period that previously undistributed earnings of certain international subsidiaries no longer meet the requirements of indefinite reinvestment, the Company recognizes the income tax expense in that period.

The Company provides reserves for potential payments of tax to various tax authorities related to uncertain tax positions and other issues. These reserves are based on a determination of whether and how much of a tax benefit taken by the Company in its tax filings or positions is more likely than not to be realized following resolution of any potential contingencies present related to the tax benefit. Potential interest and penalties associated with such uncertain tax positions is recorded as a component of income tax expense. See Note 8 below for additional details.

The Company uses an individual unit of account approach for releasing the income tax effects of unrealized gains and losses from Accumulated Other Comprehensive Income ("AOCI").

Property, Plant and Equipment: The Company depreciates property, plant and equipment using the straight-line method over its estimated useful lives, which generally fall within the following ranges: buildings- 10 to 40 years; leasehold improvements-estimated useful life or remaining term of lease, whichever is shorter; and machinery and equipment- 3 to 8 years. Certain tooling costs are capitalized and amortized over a 3-year life, while repairs and maintenance costs are expensed.

Asset Retirement Obligations: The Company records obligations associated with its lease obligations, the retirement of tangible long-lived assets and the associated asset retirement costs in accordance with authoritative guidance on asset retirement obligations. The Company reviews legal obligations associated with the retirement of long-lived assets that result from contractual obligations or the acquisition, construction, development and/or normal use of the assets. If it is determined that a legal obligation exists, regardless of whether the obligation is conditional on a future event, the fair value of the liability for an asset retirement obligation is recognized in the period in which it is incurred, if a reasonable estimate of fair value can be made. The fair value of the liability is added to the carrying amount of the associated asset, and this additional carrying amount is depreciated over the life of the asset. The difference between the gross expected future cash flow and its present value is accreted over the life of the related lease as interest expense. The amounts recorded in the consolidated financial statements are not material to any year presented.

Pension and Other Postretirement Benefits: The Company sponsors both funded and unfunded U.S. and non-U.S. defined benefit pension plans and other postretirement benefits. The Company immediately recognizes actuarial gains and losses in operating results in the year in which the gains and losses occur. Actuarial gains and losses are measured annually as of the calendar month-end that is closest to the Company's fiscal year end and accordingly will be recorded in the fourth quarter, unless the Company is required to perform an interim remeasurement. The remaining components of pension expense, primarily service and interest costs and assumed return on plan assets, are recorded on a quarterly basis. The Company’s funding policy provides that payments to the U.S. pension trusts shall at least be equal to the minimum funding requirements of the Employee Retirement Income Security Act of 1974. Non-U.S. plans are accrued for, but generally not fully funded, and benefits are paid from operating funds.

Translation of Foreign Currencies: For foreign operations, asset and liability accounts are translated at current exchange rates; income and expenses are translated using weighted average exchange rates for the reporting period. Resulting translation adjustments, as well as translation gains and losses from certain intercompany transactions considered permanent in nature, are reported in accumulated other comprehensive (loss) income, a separate component of stockholders’ equity. Gains and losses arising from transactions and translation of period-end balances denominated in currencies other than the functional currency are included in other expense, net.

Business Combinations: Business combinations are accounted for at fair value. Acquisition costs are expensed as incurred and recorded in selling, general and administrative expenses; previously held equity interests are valued at fair value upon the acquisition of a controlling interest; in-process research and development (“IPR&D”) is recorded at fair value as an intangible asset at the acquisition date; restructuring costs associated with a business combination are expensed subsequent to the acquisition date; and changes in deferred tax asset valuation allowances and income tax uncertainties after the acquisition date affect income tax expense. Measurement period adjustments are made in the period in which the amounts are determined and the current period income effect of such adjustments will be calculated as if the adjustments had been completed as of the acquisition date. All changes that do not qualify as measurement period adjustments are also included in current period earnings. The accounting for business combinations requires estimates and judgment as to expectations for future cash flows of the acquired business, and the allocation of those cash flows to identifiable intangible assets, in determining the estimated fair value for assets acquired and liabilities assumed. The fair values assigned to tangible and intangible assets acquired and liabilities assumed, including contingent consideration, are based on management’s estimates and assumptions, as well as other information compiled by management, including valuations that utilize customary valuation procedures and techniques. If the actual results differ from the estimates and judgments used in these estimates, the amounts recorded in the financial statements could result in a possible impairment of the intangible assets and goodwill, require acceleration of the amortization expense of finite-lived intangible assets, or the recognition of additional consideration which would be expensed.

Goodwill and Other Intangible Assets: The Company’s intangible assets consist of (i) goodwill, which is not being amortized; (ii) indefinite lived intangibles, which consist of a trade name that is not subject to amortization; and (iii) amortizing intangibles, which consist of patents, trade names and trademarks, licenses, customer relationships and purchased technologies, which are being amortized over their estimated useful lives.

The process of testing goodwill for impairment involves the determination of the fair value of the applicable reporting units. The test consists of the comparison of the fair value to the carrying value of the reporting unit to determine if the carrying value exceeds the fair value. If the carrying value of the reporting unit exceeds its fair value, an impairment loss in an amount equal to that excess is recognized up to the amount of goodwill. This annual impairment assessment is performed by the Company on the later of January 1 or the first day of each fiscal year. Non-amortizing intangibles are also subject to an annual impairment test. The impairment test consists of a comparison of the fair value of the non-amortizing intangible asset with its carrying amount. If the carrying amount of a non-amortizing intangible asset exceeds its fair value, an impairment loss in an amount equal to that excess is recognized up to the amount of the amortizing intangible asset. In addition, the Company evaluates the remaining useful life of its non-amortizing intangible asset at least annually to determine whether events or circumstances continue to support an indefinite useful life. If events or circumstances indicate that the useful life of non-amortizing intangible asset is no longer indefinite, the asset will be tested for impairment. The intangible asset will then be amortized prospectively over its estimated remaining useful life and accounted for in the same manner as other intangible assets that are subject to amortization. Amortizing intangible assets are reviewed for impairment when indicators of impairment are present. When a potential impairment has been identified, forecasted undiscounted net cash flows of the operations to which the asset relates are compared to the current carrying value of the long-lived assets present in that operation. If such cash flows are less than such carrying amounts, long-lived assets, including such intangibles, are written down to their respective fair values. See Note 14 below for additional details.

Stock-Based Compensation: The Company accounts for stock-based compensation expense based on estimated grant date fair value, generally using the Black-Scholes option-pricing model. The fair value is recognized as expense in the consolidated financial statements over the requisite service period. The determination of fair value and the timing of expense using option pricing models such as the Black-Scholes model require the input of highly subjective assumptions, including the expected term and the expected price volatility of the underlying stock. The Company estimates the expected term assumption based on historical experience. In determining the Company’s expected stock price volatility assumption, the Company reviews both the historical and implied volatility of the Company’s common stock, with implied volatility based on the implied volatility of publicly traded options on the Company’s common stock. The Company has one stock-based compensation plan from which it makes grants, which is described more fully in Note 20 below.

Marketable Securities and Investments: The cost of securities sold is based on the specific identification method. If securities are classified as available for sale, the Company records these investments at their fair values with unrealized gains and losses included in accumulated other comprehensive (loss) income. Under the cost method of accounting, equity investments in private companies are carried at cost and are adjusted for other-than-temporary declines in fair value, additional investments or distributions.

Cash and Cash Equivalents: The Company considers all highly liquid unrestricted instruments with a purchased maturity of three months or less to be cash equivalents. The carrying amount of cash equivalents approximates fair value due to the short maturities of these instruments.

Environmental Matters: The Company accrues for costs associated with the remediation of environmental pollution when it is probable that a liability has been incurred and the Company’s proportionate share of the amount can be reasonably estimated. The recorded liabilities have not been discounted.

Research and Development: Research and development costs are expensed as incurred. The fair value of acquired IPR&D costs are recorded at fair value as an intangible asset at the acquisition date and amortized once the product is ready for sale or expensed if abandoned.

Restructuring Charges: In recent fiscal years, the Company has undertaken a series of restructuring actions related to the impact of acquisitions and divestitures, the alignment of its operations with its growth strategy, the integration of its business units and its productivity initiatives. In connection with these initiatives, the Company has recorded restructuring charges, as more fully described in Note 6 below. Generally, costs associated with an exit or disposal activity are recognized when the liability is incurred. Prior to recording restructuring charges for employee separation agreements, the Company notifies all employees of termination. Costs related to employee separation arrangements requiring future service beyond a specified minimum retention period are recognized over the service period. Costs related to lease terminations are recorded at the fair value of the liability based on the remaining lease rental payments, reduced by estimated sublease rentals that could be reasonably obtained for the property, at the date the Company ceases use.

Comprehensive Income: Comprehensive income is defined as net income or loss and other changes in stockholders’ equity from transactions and other events from sources other than stockholders. Comprehensive income is reflected in the consolidated statements of comprehensive income.

Derivative Instruments and Hedging: Derivatives are recorded on the consolidated balance sheets at fair value. Accounting for gains or losses resulting from changes in the values of those derivatives depends on the use of the derivative instrument and whether it qualifies for hedge accounting.

For a cash flow hedge, the effective portion of the derivative’s gain or loss is initially reported as a component of other comprehensive income and subsequently amortized into net earnings when the hedged exposure affects net earnings. Cash flow hedges related to anticipated transactions are designated and documented at the inception of each hedge by matching the terms of the contract to the underlying transaction. The Company classifies the cash flows from hedging transactions in the same categories as the cash flows from the respective hedged items. Once established, cash flow hedges are generally recorded in other comprehensive income, unless an anticipated transaction is no longer likely to occur, and subsequently amortized into net earnings when the hedged exposure affects net earnings. Discontinued or dedesignated cash flow hedges are immediately settled with counterparties, and the related accumulated derivative gains or losses are recognized into net earnings on the consolidated financial statements. Settled cash flow hedges related to forecasted transactions that remain probable are recorded as a component of other comprehensive (loss) income and are subsequently amortized into net earnings when the hedged exposure affects net earnings. Forward contract effectiveness for cash flow hedges is calculated by comparing the fair value of the contract to the change in value of the anticipated transaction using forward rates on a monthly basis. The Company also has entered into other foreign currency forward contracts that are not designated as hedging instruments for accounting purposes. These contracts are recorded at fair value, with the changes in fair value recognized into interest and other expense, net on the consolidated financial statements.

The Company also uses foreign currency denominated debt to hedge its investments in certain foreign subsidiaries. Realized and unrealized translation adjustments from these hedges are included in the foreign currency translation component of AOCI, as well as the offset translation adjustments on the underlying net assets of foreign subsidiaries. The cumulative translation gains or losses will remain in AOCI until the foreign subsidiaries are liquidated or sold.

Recently Issued Accounting Pronouncements: From time to time, new accounting pronouncements are issued by the Financial Accounting Standards Board (the "FASB") and are adopted by the Company as of the specified effective dates. Unless otherwise discussed, such pronouncements did not have or will not have a significant impact on the Company’s consolidated financial position, results of operations and cash flows or do not apply to the Company’s operations.

In August 2018, the FASB issued Accounting Standards Update No. 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 ("ASU 2018-15"). ASU 2018-15 aligns the accounting for implementation costs incurred in a hosting arrangement that is a service contract with the guidance on capitalizing costs associated with developing or obtaining internal-use software (and hosting arrangements that include an internal-use software license). Specifically, ASU 2018-15 amends Intangibles-Goodwill and Other (Topic 350) to include in its scope implementation costs incurred in a hosting arrangement that is a service contract and clarifies that a customer should apply Subtopic 350-40 to determine which implementation costs to capitalize as an asset related to the service contract and which costs to expense. The provisions of this guidance are to be applied either retrospectively or prospectively to all implementation costs incurred after the date of adoption. ASU 2018-15 is effective for annual reporting periods beginning after December 15, 2019, and interim periods within those years with early adoption permitted. The Company is currently evaluating the requirements of this guidance and has not yet determined the impact of its adoption on the Company's consolidated financial position, results of operations and cash flows.

In August 2018, the FASB issued Accounting Standards Update No. 2018-14, Compensation - Retirement Benefits - Defined Benefit Plans - General (Subtopic 715-20): Disclosure Framework - Changes to the Disclosure Requirements for Defined Benefit Plans ("ASU 2018-14"). ASU 2018-14 adds, removes, and clarifies disclosure requirements related to defined benefit pension and other postretirement plans. ASU 2018-14 adds requirements for an entity to disclose the weighted-average interest crediting rates used in the entity’s cash balance pension plans and other similar plans; and an explanation of the reasons for significant gains and losses related to changes in the benefit obligation for the period. Further, ASU 2018-14 removes guidance that currently requires the following disclosures: the amounts in accumulated other comprehensive income expected to be recognized as part of net periodic benefit cost over the next year; the amount and timing of plan assets expected to be returned to the employer; information about (1) benefits covered by related-party insurance and annuity contracts and (2) significant transactions between the plan and related parties; and the effects of a one-percentage-point change on the assumed health care costs and the effect of this change in rates on service cost, interest cost, and the benefit obligation for postretirement health care benefits. ASU 2018-14 also clarifies the guidance in Compensation-Retirement Benefits (Topic 715-20-50-3) on defined benefit plans to require disclosure of (1) the projected benefit obligation ("PBO") and fair value of plan assets for pension plans with PBOs in excess of plan assets (the same disclosure with reference to the accumulated postretirement benefit obligation rather than the PBO is required for other postretirement benefit plans) and (2) the accumulated benefit obligation ("ABO") and fair value of plan assets for pension plans with ABOs in excess of plan assets. The provisions of this guidance are to be applied retrospectively to all periods presented upon their effective date. ASU 2018-14 is effective for annual reporting periods beginning after December 15, 2020, and interim periods within those years with early adoption permitted. The Company is currently evaluating the requirements of this guidance and has not yet determined the impact of its adoption on the Company's consolidated financial position, results of operations and cash flows.

In August 2018, the FASB issued Accounting Standards Update No. 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement ("ASU 2018-13"). ASU 2018-13 adds, removes, and modifies certain disclosures related to fair value measurements. ASU 2018-13 adds requirements for an entity to disclose the changes in unrealized gains and losses for the period included in other comprehensive income for recurring Level 3 fair value measurements held at the end of the reporting period; and the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements. Further, ASU 2018-13 removes the requirement to disclose the amount of and reasons for transfers between Level 1 and Level 2 of the fair value hierarchy; the policy for timing of transfers between levels; and the valuation processes for Level 3 fair value measurements. ASU 2018-13 also modifies existing disclosure requirements related to measurement uncertainty. The amendments regarding changes in unrealized gains and losses, the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements, and the narrative description of measurement uncertainty are to be applied prospectively for only the most recent interim or annual period presented in the initial fiscal year of adoption. All other amendments are to be applied retrospectively to all periods presented upon their effective date. ASU 2018-13 is effective for annual reporting periods beginning after December 15, 2019, and interim periods within those years. Early adoption is permitted for any removed or modified disclosures. The Company is currently evaluating the requirements of this guidance and has not yet determined the impact of its adoption on the Company's consolidated financial position, results of operations and cash flows.

In June 2018, the FASB issued Accounting Standards Update No. 2018-07, Compensation - Stock Compensation (Topic 718), Improvements to Nonemployee Share-Based Payment Accounting ("ASU 2018-07") which supersedes Subtopic 505-50, Equity - Equity-Based Payments to Non-employees, and expands the scope of Topic 718 (which currently only includes share-based payments to employees) to also include share-based payments issued to non-employees for goods and services, except for specific guidance on inputs to an option pricing model and the attribution of cost (that is, the period of time over which share-based payment awards vest and the pattern of cost recognition over that period). ASU 2018-07 specifies that Topic 718 applies to all share-based payment transactions in which a grantor acquires goods or services to be used or consumed in a grantor’s own operations by issuing share-based payment awards, except for financing transactions, or awards issued to customers as part of a contract accounted for under Topic 606, Revenue from Contracts with Customers ("Topic 606"). The provisions of this guidance are to be applied using a modified retrospective approach, with a cumulative-effect adjustment to retained earnings as of the beginning of the fiscal year, for all (1) liability-classified non-employee awards that have not been settled as of the adoption date and (2) equity-classified non-employee awards for which a measurement date has not been established. ASU 2018-07 is effective for annual reporting periods beginning after December 15, 2018, and interim periods within those years. Early adoption is permitted, but no earlier than a company’s adoption date of Topic 606. The Company early adopted the provisions of this guidance effective July 2, 2018. The adoption did not have a material impact on the Company's consolidated financial position, results of operations and cash flow.

In March 2018, the FASB Issued Accounting Standards Update No. 2018-05, Income Taxes (Topic 740): Amendments to SEC Paragraphs Pursuant to SEC Staff Accounting Bulletin No. 118 ("ASU 2018-05"). ASU 2018-05 was issued to incorporate into Topic 740 recent SEC guidance related to the income tax accounting implications of the Tax Cut and Jobs Act (the "Tax Act"). The SEC issued Staff Accounting Bulletin No. 118 ("SAB 118") to address concerns about reporting entities’ ability to timely comply with the accounting requirements to recognize all of the effects of the Tax Act in the period of enactment. SAB 118 permits companies to disclose that some or all of the income tax effects from the Tax Act are incomplete by the due date of the financial statements, and if possible, disclose a reasonable estimate of such tax effects. ASU 2018-05 is effective immediately. The Company is applying the guidance in ASU 2018-05 when accounting for the enactment date effects of the Tax Act. At December 30, 2018, the Company completed the accounting for all of the tax effects of the Tax Act using reasonable estimates of their effects based on currently available information. These estimates may be affected as additional clarification and implementation guidance becomes available. These changes could be material to the Company's income tax expense. See Note 8 for further disclosures.

In February 2018, the FASB Issued Accounting Standards Update No. 2018-03, Technical Corrections and Improvements to Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities ("ASU 2018-03"). ASU 2018-03 was issued to clarify certain aspects of guidance concerning the recognition of financial assets and liabilities established in Accounting Standards Update No. 2016-01, Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities ("ASU 2016-01"). This includes treatment for discontinuations and adjustments for equity securities without a readily determinable market value, forward contracts and purchased options, presentation requirements for certain fair value option liabilities, fair value option liabilities denominated in a foreign currency, and transition guidance for equity securities without a readily determinable fair value. ASU 2018-03 is effective for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years beginning after June 15, 2018. Early adoption is permitted for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years, as long as the Company has adopted ASU 2016-01. The Company adopted the provisions of this guidance effective July 2, 2018. The adoption did not have a material impact on the Company's consolidated financial position, results of operations and cash flows.

In February 2018, the FASB Issued Accounting Standards Update No. 2018-02, Income Statement-Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income ("ASU 2018-02"). ASU 2018-02 provides entities with an option to reclassify stranded tax effects within AOCI to retained earnings in each period in which the effect of the change in the U.S. federal corporate income tax rate in the Tax Act (or portion thereof) is recorded. ASU 2018-02 requires entities to disclose a description of the accounting policy for releasing income tax effects from AOCI; whether they elect to reclassify the stranded income tax effects from the Tax Act; and information about the other income tax effects that are reclassified. ASU 2018-02 is effective for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. Early adoption is permitted, and entities should apply the proposed amendments either in the period of adoption or retrospectively to each period (or periods) in which the effect of the change in the U.S. federal corporate income tax rate in the Tax Act is recognized. The Company adopted ASU 2018-02 on December 30, 2018. The adoption of the standard resulted in an increase in retained earnings at December 30, 2018 in the amount of $6.5 million, with a corresponding decrease in AOCI. The adoption did not have a material impact on the Company's consolidated financial position, results of operations and cash flows, other than the impact discussed above.

In August 2017, the FASB issued Accounting Standards Update No. 2017-12, Derivatives and Hedging (Topic 815), Targeted Improvements to Accounting for Hedging Activities ("ASU 2017-12"), which amends the hedge accounting recognition and presentation requirements in Topic 815. ASU 2017-12 makes targeted changes to the existing hedge accounting model to better align an entity’s financial reporting for hedging relationships with the entity’s risk management activities, and to reduce the complexity of, and simplify the application of, the hedge accounting model. Specifically, ASU 2017-12 expands the types of transactions eligible for hedge accounting, eliminates the requirement to separately measure and present hedge ineffectiveness, simplifies the way assessments of hedge ineffectiveness may be performed, relaxes the documentation requirements for entering into hedging positions, provides targeted improvements to fair value hedges of interest rate risk, and permits an entity to exclude the change in the fair value of cross-currency basis spreads in currency swaps from the assessment of hedge effectiveness. The standard also requires entities to provide new disclosures about the impact fair value and cash flow hedges have on their income statements and about cumulative basis adjustments arising from fair value hedges. The provisions of this guidance are to be applied using a modified retrospective approach to existing hedging relationships as of the adoption date. However, the transition provisions allow for certain elections at the date of adoption and entities may choose to apply any of the provided elections. ASU 2017-12 is effective for annual reporting periods beginning after December 15, 2018, and interim periods within those years. Early adoption is permitted, including adoption in any interim period. The Company early adopted the provisions of this guidance effective January 1, 2018. The adoption did not have a material impact on the Company's consolidated financial position, results of operations and cash flows.

In May 2017, the FASB issued Accounting Standards Update No. 2017-09, Compensation - Stock Compensation (Topic 718), Scope of Modification Accounting ("ASU 2017-09"), which amends the scope of modification accounting for share-based payment arrangements. ASU 2017-09 provides guidance on the types of changes to the terms or conditions of share-based payment awards to which an entity would be required to apply modification accounting under Topic 718. Specifically, an entity would not apply modification accounting if the fair value, vesting conditions, and classification of the awards are the same immediately before and after the modification. If an entity modifies its awards and concludes that it is not required to apply modification accounting under the standard, it must still consider whether the modification affects its application of other guidance. Additionally, if a significant modification does not result in incremental compensation cost, entities are required to disclose the “lack of” incremental compensation cost resulting from such significant modification. The standard also removes the guidance in Topic 718 stating that modification accounting is not required when an entity adds an antidilution provision as long as that modification is not made in contemplation of an equity restructuring. The provisions of this guidance are to be applied on a prospective basis to awards modified on or after the effective date. ASU 2017-09 is effective for annual reporting periods beginning after December 15, 2017, and interim periods within those years. Early adoption is permitted, including adoption in any interim period. The Company adopted ASU 2017-09 effective January 1, 2018. The adoption did not have a material impact on the Company's consolidated financial position, results of operations and cash flows.

In March 2017, the FASB issued Accounting Standards Update No. 2017-07, Compensation - Retirement Benefits (Topic 715), Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost ("ASU 2017-07"), which amends the requirements in Topic 715 related to the income statement presentation of the components of net periodic benefit cost for an entity’s sponsored defined benefit pension and other postretirement plans. ASU 2017-07 requires entities to (1) disaggregate the current-service-cost component from the other components of net benefit cost (the “other components”) and present it with other current employee compensation costs in their income statements and (2) present the other components elsewhere in their income statements and outside of income from operations, and disclose the income statement lines that contain the other components if they are not presented on appropriately described separate lines. Additionally, the standard requires that only the service-cost component of net benefit cost is eligible for capitalization (e.g., as part of inventory or property, plant, and equipment). The change in income statement presentation requires retrospective application, while the change in capitalized benefit cost is to be applied prospectively. ASU 2017-07 is effective for annual reporting periods beginning after December 15, 2017, and interim periods within those years, with early adoption permitted. The standard provides a practical expedient that permits entities to use the components of cost disclosed in prior years as a basis for the retrospective application of the new income statement presentation. Entities need to disclose the use of the practical expedient. The Company adopted ASU 2017-07 effective January 1, 2018 using a retrospective approach for each period presented. For the fiscal years 2017 and 2016, $(9.2) million and $11.5 million, respectively, of net periodic pension (credit) cost previously presented within operating income has been presented outside of operating income in the line item "Interest and other expense, net" in the consolidated statements of operations due to the retrospective adoption of ASU 2017-07. The adoption did not have a material impact on the Company's consolidated financial position, results of operations and cash flows, other than the impact discussed above.

In January 2017, the FASB issued Accounting Standards Update No. 2017-01, Business Combinations (Topic 805), Clarifying the Definition of a Business ("ASU 2017-01"), which amends Topic 805 to provide a screen to determine when a set of assets and liabilities is not a business. The screen requires that when substantially all of the fair value of the gross assets acquired (or disposed of) is concentrated in a single identifiable asset or a group of similar identifiable assets, the set is not a business. This screen reduces the number of transactions that need to be further evaluated. If the screen is not met, the standard (1) requires that to be considered a business, a set must include, at a minimum, an input and a substantive process that together significantly contribute to the ability to create output and (2) removes the evaluation of whether a market participant could replace missing elements. The standard provides a framework to assist entities in evaluating whether both an input and a substantive process are present. The standard also provides a framework that includes two sets of criteria to consider that depend on whether a set has outputs and a more stringent criteria for sets without outputs. Lastly, the standard narrows the definition of the term "output" so that the term is consistent with how outputs are described in Topic 606, Revenue from Contracts with Customers. The provisions of this guidance are to be applied prospectively. ASU 2017-01 is effective for annual reporting periods beginning after December 15, 2017, and interim periods within those years, with early adoption permitted in limited circumstances. The Company adopted ASU 2017-01 effective January 1, 2018. The adoption did not have a material impact on the Company's consolidated financial position, results of operations and cash flows.

In November 2016, the FASB issued Accounting Standards Update No. 2016-18, Statement of Cash Flows (Topic 230), Restricted Cash ("ASU 2016-18"), which amends Topic 230 to add or clarify guidance on the classification and presentation of restricted cash in the statement of cash flows. The standard requires that a statement of cash flows explain the change during the period in the total of cash, cash equivalents and amounts generally described as restricted cash or restricted cash equivalents. Therefore, amounts generally described as restricted cash and restricted cash equivalents should be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. The provisions of this guidance are to be applied using a retrospective transition method to each period presented. ASU 2016-18 is effective for annual reporting periods beginning after December 15, 2017, and interim periods within those years, with early adoption permitted. The Company adopted ASU 2016-18 effective January 1, 2018. For the fiscal years 2017 and 2016, $17.2 million and $(17.0) million, respectively, of changes in restricted cash balances that were previously presented within investing activities in the consolidated statements of cash flows have been excluded from the cash flows used in investing activities and the effect of exchange rate changes increased by $0.2 million in fiscal year 2017, due to the retrospective adoption of ASU 2016-18. Restricted cash amounting to $17.3 million and $0.2 million at January 1, 2017 and December 31, 2017, respectively, have been included with the cash and cash equivalents when reconciling the beginning of period and end of period total amounts on the consolidated statement of cash flows for the fiscal year ended December 31, 2017. Restricted cash amounting to $0.3 million and $17.3 million at January 3, 2016 and January 1, 2017, respectively, have been included with the cash and cash equivalents when reconciling the beginning of period and end of period total amounts on the consolidated statement of cash flows for the fiscal year ended January 1, 2017. The adoption did not have a material impact on the Company's consolidated financial position, results of operations and cash flows, other than the impact discussed above.

In October 2016, the FASB issued Accounting Standards Update No. 2016-16, Income Taxes (Topic 740), Intra-entity Transfer of Assets Other than Inventory ("ASU 2016-16"). ASU 2016-16 removes the prohibition in Topic 740 against the immediate recognition of the current and deferred income tax effects of intra-entity transfers of assets other than inventory. The standard requires entities to recognize the income tax consequences of an intra-entity transfer of an asset other than inventory when the transfer occurs. The provisions of this guidance are to be applied on a modified retrospective basis through a cumulative-effect adjustment directly to retained earnings as of the beginning of the period of adoption. ASU 2016-16 is effective for annual reporting periods beginning after December 15, 2017, and interim periods within those years, with early adoption permitted. The Company adopted ASU 2016-16 on January 1, 2018. The adoption of the standard resulted in a decrease in the retained earnings at January 1, 2018 of approximately $2.1 million with corresponding increase in deferred tax assets of $10.7 million and decrease in prepaid taxes of $12.8 million related to prior years’ intra-entity transfers of assets other than inventory. The adoption did not have a material impact on the Company's consolidated financial position, results of operations and cash flows, other than the impact discussed above.

In August 2016, the FASB issued Accounting Standards Update No. 2016-15, Statement of Cash Flows (Topic 230), Classification of Certain Cash Receipts and Cash Payments ("ASU 2016-15"). ASU 2016-15 addresses eight specific cash flow issues with the objective of reducing the existing diversity in practice in how certain cash receipts and cash payments are presented and classified in the statement of cash flows under Topic 230 and other topics. The provisions of this guidance are to be applied using a retrospective transition method to each period presented, and if it is impracticable to apply the amendments retrospectively for some of the issues, ASU 2016-15 allows the amendments for those issues to be applied prospectively as of the earliest date practicable. ASU 2016-15 is effective for annual reporting periods beginning after December 15, 2017, and interim periods within those years, with early adoption permitted. The Company adopted ASU 2016-15 effective January 1, 2018. The adoption did not have a material impact on the Company's consolidated financial position, results of operations and cash flows.

In June 2016, the FASB issued Accounting Standards Update No. 2016-13, Financial Instruments - Credit Losses (Topic 326), Measurement of Credit Losses on Financial Instruments ("ASU 2016-13"). ASU 2016-13 changes how entities will measure credit losses for most financial assets and certain other instruments that are not measured at fair value through net income. The standard requires entities to use the expected loss impairment model and 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, net investments in leases and off-balance sheet credit exposures. Entities are required to estimate the lifetime “expected credit loss” for each applicable financial asset and record an allowance that, when deducted from the amortized cost basis of the financial asset, presents the net amount expected to be collected on the financial asset. The standard also amends the impairment model for available-for-sale (“AFS”) debt securities and requires entities to determine whether all or a portion of the unrealized loss on an AFS debt security is a credit loss. An entity will recognize an allowance for credit losses on an AFS debt security as a contra-account to the amortized cost basis rather than as a direct reduction of the amortized cost basis of the investment. The provisions of this guidance are to be applied using a modified-retrospective approach. A prospective transition approach is required for debt securities for which an other-than-temporary impairment had been recognized before the effective date. ASU 2016-13 is effective for annual reporting periods beginning after December 15, 2019, and interim periods within those years. Early adoption is permitted for annual periods beginning after December 15, 2018, and interim periods therein. The Company is currently evaluating the requirements of this guidance and has not yet determined the impact of its adoption on the Company's consolidated financial position, results of operations and cash flows.

In February 2016, the FASB issued Accounting Standards Update No. 2016-02, Leases ("ASU 2016-02"). ASU 2016-02 requires organizations that lease assets to recognize assets and liabilities on the balance sheet related to the rights and obligations created by those leases, regardless of whether they are classified as finance or operating leases. Consistent with current guidance, the recognition, measurement, and presentation of expenses and cash flows arising from a lease of assets will primarily depend on its classification as a finance or operating lease. ASU 2016-02 also requires new disclosures to help financial statement users better understand the amount, timing, and uncertainty of cash flows arising from leases. The provisions of this guidance are effective for annual periods beginning after December 15, 2018, and interim periods within those years, with early adoption permitted. ASU 2016-02 is to be applied using a modified retrospective approach. Subsequent to the issuance of ASU 2016-02, in July 2018, the FASB issued Accounting Standards Update No. 2018-10, Codification Improvements to Topic 842, Leases ("ASU 2018-10") and Accounting Standards Update No. 2018-11, Leases (Topic 842): Targeted Improvements ("ASU 2018-11"). The amendments in ASU 2018-10 clarify, correct or remove inconsistencies in the guidance provided under ASU 2016-02 related to sixteen specific issues identified. The amendments in ASU 2018-11 provide entities with an additional (and optional) transition method to adopt the new leases standard. Under the new transition method, an entity initially applies the new leases standard at the adoption date and recognizes a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption. Consequently, an entity's reporting for the comparative periods presented in the financial statements in the period of adoption will continue to be in accordance with ASC 840, Leases ("ASC 840"). An entity that elects this additional (and optional) transition method must provide the required disclosures under ASC 840 for all periods that continue to be in accordance with ASC 840. ASU 2018-11 also provides lessors with a practical expedient, by class of underlying asset, to not separate nonlease components from the associated lease component and, instead, to account for those components as a single component if certain criteria are met. The effective date and transition requirements for these two standards are the same as the effective date and transition requirements of ASU 2016-02. The standards were effective for the Company beginning on December 31, 2018. The Company did not early adopt these standards and adopted these standards using the optional transition method.

The Company elected to apply the modified retrospective approach, and applied the new leases standard at December 31, 2018, with a cumulative effect adjustment recognized in the opening balance of retained earnings in fiscal year 2019. As a lessee, the most significant impact of the standards relates to the recognition of the right-of-use assets and lease liabilities for the operating leases in the balance sheet. In addition, the Company had deferred gains from a sale-leaseback transaction that are being amortized in operating expenses over the lease term and the lease is accounted for as an operating lease under ASC 840. Under the new standards, the Company will recognize the deferred gains from the sale as a cumulative-effect adjustment in retained earnings at December 31, 2018. The Company will also derecognize the impact of its build-to-suit arrangement in which the Company was the deemed owner during the construction period, for which the construction is complete and the lease commenced before the initial date of adoption. The adoption of the standards will result in an increase in retained earnings at December 31, 2018 of approximately $19.1 million for the cumulative effect of initially applying the standards as of that date. In addition, the adoption of the standards will result in recognition of right-of-use assets of approximately $190.7 million and lease liabilities of approximately $137.7 million, primarily related to the facilities operating leases, a decrease in property and equipment of approximately $31.9 million and an increase in deferred tax liabilities of $2.1 million for the tax impact of the cumulative adjustments. The adoption will have no impact to cash from or used in operating, investing or financing activities in the Company's consolidated statement of cash flows at December 31, 2018.

In May 2014, the FASB issued Accounting Standards Update No. 2014-09, Revenue from Contracts with Customers ("ASU 2014-09"). Under this new guidance, an entity should use a five-step process to recognize revenue, depicting 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. The standard also requires new disclosures regarding the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. Subsequent to the issuance of the standard, the FASB decided to defer the effective date for one year to annual reporting periods beginning after December 15, 2017, with early adoption permitted for annual reporting periods beginning after December 15, 2016. In November 2017, the FASB also issued Accounting Standards Update No. 2017-14, Income Statement-Reporting Comprehensive Income (Topic 220), Revenue Recognition (Topic 605), and Revenue from Contracts with Customers (Topic 606). ASU 2017-14 includes amendments to certain SEC paragraphs within the FASB Accounting Standards Codification ("Codification"). ASU 2017-14 amends the Codification to incorporate SEC Staff Accounting Bulletin No. 116 and SEC Interpretive Release on Vaccines for Federal Government Stockpiles (SEC Release No. 33-10403) to align existing SEC staff guidance with Revenue from Contracts with Customers (Topic 606). In May 2016, the FASB also issued Accounting Standards Update No. 2016-12, Revenue from Contracts with Customers (Topic 606), Narrow-Scope Improvements and Practical Expedients ("ASU 2016-12"), which amended its revenue recognition guidance in ASU 2014-09 on transition, collectability, non-cash consideration, contract modifications and completed contracts at transition and the presentation of sales and other similar taxes collected from customers. In April 2016, the FASB also issued Accounting Standards Update No. 2016-10, Revenue from Contracts with Customers (Topic 606), Identifying Performance Obligations and Licensing ("ASU 2016-10"), which amended its revenue recognition guidance in ASU 2014-09 on identifying performance obligations to allow entities to disregard items that are immaterial in the context of the contract, clarify when a promised good or service is separately identifiable (i.e., distinct within the context of the contract) and allow an entity to elect to account for the cost of shipping and handling performed after control of a good has been transferred to the customer as a fulfillment cost (i.e., an expense). ASU 2016-10 also clarifies how an entity should evaluate the nature of its promise in granting a license of intellectual property ("IP") and requires entities to classify IP in one of two categories: functional IP or symbolic IP, which will determine whether it recognizes revenue over time or at a point in time. ASU 2016-10 also address how entities should consider license renewals and restrictions and apply the exception for sales- and usage-based royalties received in exchange for licenses of IP. In March 2016, the FASB also issued Accounting Standards Update No. 2016-08, Revenue from Contracts with Customers (Topic 606), Principal versus Agent Considerations (Reporting Revenue Gross versus Net) ("ASU 2016-08"), which amended the principal-versus-agent implementation guidance and illustrations in ASU 2014-09. ASU 2016-08 clarifies that an entity should evaluate when it is the principal or agent for each specified good or service promised in a contract with a customer. ASU 2017-14, ASU 2016-12, ASU 2016-10, ASU 2016-08 and ASU 2014-09 may be adopted either using a full retrospective approach or a modified retrospective approach. The standards were effective for the Company beginning on January 1, 2018. The Company did not early adopt these standards and adopted these standards using the modified retrospective approach.

The most significant impact of the standards relates to the accounting for certain transactions with multiple elements or “bundled” arrangements. Specifically, for sales of software subscriptions or sales of licenses and maintenance, the Company will recognize the license revenue predominantly at the time of billing and delivery rather than recognizing the entire sales price ratably over the maintenance period, which is the Company's previous practice. In addition, for certain sales of instruments that include customer-specified acceptance criteria, the Company will recognize revenue when the customer obtains control of the instrument which is typically upon delivery or when title has transferred to the customer, as the Company believes acceptance is perfunctory. The Company will also capitalize incremental commission fees as a result of obtaining contracts when these fees are recoverable and will amortize the assets based on the transfer of goods or services to which the assets relate which typically range from two to six years. The Company elected to apply the modified retrospective approach only to contracts not completed as of January 1, 2018. The adoption of the standards resulted in an increase in the retained earnings at January 1, 2018 of approximately $10.2 million for the cumulative effect of initially applying the standards at January 1, 2018. In addition, the adoption of the standards resulted primarily in a reduction in deferred revenue of approximately $11.5 million, mainly driven by the upfront recognition of license revenue and certain multi-year software subscriptions, and an increase in deferred tax liability of approximately $3.0 million for the tax impact of the cumulative adjustments. The cumulative effect of recognizing instrument sales upon delivery or transfer of title and capitalizing the incremental commission fees were not material at January 1, 2018. The adoption of the standards had no impact to cash from or used in operating, investing, or financing activities in the Company's consolidated statement of cash flows at January 1, 2018. Refer to Note 3, Changes in Accounting Policies, for the impact of adoption of the standards on the Company's consolidated financial statements for the fiscal year ended December 30, 2018. Also refer to Note 2, Revenue, for the disclosures required by the standards.
