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 29, 2019 ("fiscal year 2019"), December 30, 2018 ("fiscal year 2018") and December 31, 2017 ("fiscal year 2017") included 52 weeks. The fiscal year ending January 3, 2021 ("fiscal year 2020") will include 53 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 7 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 13 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 19 below. Marketable Securities and Investments: Investments in debt securities that are classified as available for sale are recorded at their fair values with unrealized gains and losses included in accumulated other comprehensive (loss) income until realized. Investments in equity securities are recorded at their fair values with unrealized holding gains and losses included in earnings. Investments in equity securities without a readily available fair value are carried at cost minus impairment, if any, plus or minus changes resulting from observable price changes in orderly transactions for the identical or a similar investment of the same issuer, with changes included in earnings. 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 and Other Costs: 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 and other charges, as more fully described in Note 5 below, which include employee severance, other exit costs as well as costs of terminating certain lease agreements or contracts and other costs associated with relocating facilities. 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. Prior to adoption of Accounting Standards Codification ("ASC") 842, Leases, costs related to lease terminations were 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 ceased 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 December 2019, the FASB issued Accounting Standards Update No. 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes ("ASU 2019-12"). ASU 2019-12 eliminates certain exceptions and adds guidance to reduce complexity in accounting for income taxes. Specifically, this guidance: (1) removes the intraperiod tax allocation exception to the incremental approach; (2) removes the ownership changes in investments exception in determining when a deferred tax liability is recognized after an investor in a foreign entity transitions to or from the equity method of accounting and applies this provision on a modified retrospective basis through a cumulative-effect adjustment to retained earnings at the beginning of the period of adoption; and (3) removes the exception to using the general methodology for calculating income taxes in an interim period when a year-to-date loss exceeds the anticipated loss for the year. ASU 2019-12 also simplifies accounting principles by making other changes, including requiring an entity to: (1) evaluate whether a step-up in tax basis of goodwill relates to a business combination or a separate transaction; (2) make a policy election to not allocate consolidated income taxes when a member of a consolidated tax return is not subject to income tax and to apply this provision retrospectively to all periods presented; and (3) recognize a franchise tax (or similar tax) that is partially based on income as an income-based tax and apply this provision either retrospectively for all periods presented or on a modified retrospective basis through a cumulative-effect adjustment to retained earnings as of the beginning of the period of adoption. The provisions of this guidance (except as specifically mentioned above) are to be applied prospectively upon their effective date. ASU 2019-12 is effective for annual reporting periods beginning after December 15, 2020, and interim periods within those years. Early adoption is permitted but requires simultaneous adoption of all provisions of this guidance. 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 April 2019, the FASB issued Accounting Standards Update No. 2019-04, Codification Improvements to Topic 326, Financial Instruments - Credit Losses, Topic 815, Derivatives and Hedging, and Topic 825, Financial Instruments ("ASU 2019-04"). ASU 2019-04 clarifies certain aspects of previously issued accounting standards related to: (1) ASU 2016-13, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Statements ("ASU 2016-13"), in areas of accrued interest receivable, transfers of loans and debt securities between classifications, recoveries and prepayments, (2) ASU 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities ("ASU 2017-12"), in areas of partial-term fair value hedges, fair value hedge basis adjustments, certain disclosures and transition requirements and (3) ASU 2016-01, Financial Instruments-Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities ("ASU 2016-01"), in areas of remeasurement of equity securities under ASC 820, Fair Value Measurement, when using the measurement alternative and remeasurement of equity securities at historical exchange rates. The amendments related to ASU 2016-13 are required to be adopted in conjunction with that accounting standards update, as further described below. Since the Company has already adopted ASU 2017-12 and ASU 2016-01, the related amendments in ASU 2019-04 are effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years, with early adoption permitted in any interim period. The amendments to ASU 2017-12 can either be adopted retrospectively as of the date of adoption of ASU 2017-12 or they can be adopted prospectively. The amendments to ASU 2016-01 are required to be applied using a modified-retrospective adoption approach with a cumulative-effect adjustment to retained earnings as of the date of adoption of ASU 2016-01, except for those related to equity securities without readily determinable fair values that are measured using the measurement alternative, which are required to be applied prospectively. The standard was effective for the Company beginning on December 30, 2019, the first day of the Company's fiscal year 2020. The Company will apply the provisions of this guidance prospectively. The adoption is not expected to have a material impact on the Company's consolidated financial position, results of operations and cash flows. 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). The provisions of this guidance are to be applied either retrospectively or prospectively to all implementation costs incurred after the date of adoption. The standard was effective for the Company beginning on December 30, 2019, the first day of the Company's fiscal year 2020. The Company will apply the provisions of this guidance prospectively. The adoption is not expected to have a material impact 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. The standard was effective for the Company beginning on December 30, 2019, the first day of the Company's fiscal year 2020. The adoption is not expected to have a material impact on the Company's disclosures related to fair value measurements. 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 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. Subsequent to the issuance of ASU 2016-13, in November 2018, the FASB issued Accounting Standards Update No. 2018-19, Codification Improvements to Topic 326, Financial Instruments - Credit Losses ("ASU 2018-19"), in April 2019, the FASB issued ASU 2019-04, and in May 2019, the FASB issued Accounting Standards Update No. 2019-05, Financial Instruments - Credit Losses (Topic 326), Targeted Transition Relief ("ASU 2019-05"). The amendments in ASU 2018-19 clarify that receivables arising from operating leases are not within the scope of Subtopic 326-20, Financial Instruments - Credit Losses - Measured at Amortized Cost. Instead, impairment of receivables arising from operating leases should be accounted for in accordance with Topic 842, Leases. The amendments in ASU 2019-04 clarify the measurement of allowance for credit losses on accrued interest receivable; the inclusion of expected recoveries in the allowance for credit losses; the permission of a prepayment-adjusted effective interest rate when determining the allowance for credit losses; and the steps entities should take when recording the transfer of loans or debt securities between measurement classifications. The amendments in ASU 2019-05 provide an option to irrevocably elect the fair value option in Subtopic 825-10, Financial Instruments-Overall, on an instrument-by-instrument basis, for eligible financial assets measured at amortized cost basis upon adoption of ASU 2016-13, but this fair value option election does not apply to held-to-maturity debt securities. The effective date and transition requirements for the amendments in ASU 2018-19, ASU 2019-04 and ASU 2019-05 are the same as the effective date and transition requirements of ASU 2016-13, which is effective for annual reporting periods beginning after December 15, 2019, and interim periods within those years. The standards were effective for the Company beginning on December 30, 2019, the first day of the Company's fiscal year 2020. The Company adopted these standards using the modified-retrospective approach. The adoption of the standard resulted in a decrease in retained earnings at December 30, 2019 of approximately $1.3 million from the cumulative effect of initially applying the standards as of that date. In addition, the adoption of the standard resulted in an increase in reserve for doubtful accounts of $1.7 million and an increase in deferred tax assets of $0.5 million from the tax impact of the cumulative adjustments. The adoption did not have an impact on cash from or used in operating, investing or financing activities in the Company's consolidated statement of cash flows at December 30, 2019. 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"), and in March 2019, the FASB issued Accounting Standards Update No. 2019-01, Leases (Topic 842): Codification Improvements ("ASU 2019-01"). 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 Accounting Standards Codification (“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. ASU 2019-01 provides clarification on implementation issues associated with adopting ASU 2016-02. ASU 2019-01 provides guidance on transition disclosures related to Topic 250, Accounting Changes and Error Corrections, specifically paragraph 205-10-50-3, which requires entities to provide in the fiscal year in which a new accounting principle is adopted the identical disclosures for interim periods after the date of adoption. The guidance in ASU 2019-01 explicitly provides an exception to the paragraph 250-10-50-3 interim disclosure requirements in the Topic 842 transition disclosure requirements. The effective date and transition requirements for these 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 first day of the Company's fiscal year 2019. The Company did not early adopt these standards and adopted these standards using the optional transition method. The Company applied the modified retrospective approach, and applied the new leases standards 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 sale-leaseback transactions that are being amortized in operating expenses over the lease terms and the leases are accounted for as operating leases under ASC 840. Under the new standards, the Company recognized the deferred gains from the sales as a cumulative effect adjustment in retained earnings at December 31, 2018. The Company also derecognized the impact of its build-to-suit arrangements 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 resulted in an increase in retained earnings at December 31, 2018 of approximately $13.3 million for the cumulative effect of initially applying the standards as of that date. In addition, the adoption of the standards resulted in the recognition of right-of-use assets of approximately $199.5 million and lease liabilities of approximately $147.1 million, primarily related to the facilities operating leases, a decrease in property and equipment of approximately $34.6 million and an increase in deferred tax liabilities of $4.6 million for the tax impact of the cumulative adjustments. The adoption did not have an impact on cash from or used in operating, investing or financing activities in the Company's consolidated statement of cash flows at December 31, 2018.
