Summary of Significant Accounting Policies | BUSINESS AND BASIS OF PRESENTATION Separation and Initial Public Offering Envista Holdings Corporation (together with its subsidiaries, “Envista” or the “Company”) was formed as a wholly-owned subsidiary of Danaher Corporation (“Danaher” or “Former Parent”). Danaher formed Envista to ultimately acquire, own and operate the Dental business of Danaher. On September 20, 2019, the Company completed an initial public offering (“IPO”) resulting in the issuance of 30.8 million shares of its common stock (including shares issued pursuant to the underwriters’ option to purchase additional shares) to the public, which represented 19.4% of the Company’s outstanding common stock, at $22.00 per share, the initial public offering price, for total net proceeds, after deducting underwriting discounts and commissions, of $643.4 million. In connection with the completion of the IPO, through a series of equity and other transactions, Danaher transferred substantially all of its Dental business to the Company. As consideration for the transfer of the Dental business to the Company, the Company paid Danaher approximately $2.0 billion, which included the net proceeds from the IPO and the net proceeds from term debt financing, as further discussed in Note 15, and issued to Danaher 127.9 million shares of the Company’s common stock. The transactions described above related to the transfer of the Dental business are collectively referred to herein as the “Separation.” On November 15, 2019, Danaher announced an exchange offer whereby Danaher stockholders could exchange all or a portion of Danaher common stock for shares of the Company’s common stock owned by Danaher. The disposition of the Company’s shares (the “Split-Off”) was completed on December 18, 2019 and resulted in the full separation of the Company and disposal of Danaher’s entire ownership and voting interest in the Company. Business Overview The Company provides products that are used to diagnose, treat and prevent disease and ailments of the teeth, gums and supporting bone, as well as to improve the aesthetics of the human smile. The Company is a worldwide provider of a broad range of dental implants, orthodontic appliances, general dental consumables, equipment and services and is dedicated to driving technological innovations that help dental professionals improve clinical outcomes and enhance productivity. The Company operates in two business segments: Specialty Products & Technologies and Equipment & Consumables. The Company’s Specialty Products & Technologies segment develops, manufactures and markets dental implant systems, dental prosthetics and associated treatment software and technologies, as well as orthodontic bracket systems, aligners and lab products. The Company’s Equipment & Consumables segment develops, manufactures and markets dental equipment and supplies used in dental offices, including digital imaging systems, software and other visualization/magnification systems; handpieces and associated consumables; treatment units and other dental practice equipment; endodontic systems and related consumables; and restorative materials and instruments, rotary burs, impression materials, bonding agents and cements and infection prevention products. Basis of Presentation For periods after the Separation, the financial statements are prepared on a consolidated basis. Prior to the Separation, the Company operated as part of Danaher and not as a separate, publicly-traded company and the Company’s financial statements are combined, have been prepared on a stand-alone basis and are derived from Danaher's consolidated financial statements and accounting records. The Consolidated and Combined Financial Statements reflect the financial position, results of operations and cash flows related to the Dental business that was transferred to the Company. All revenues and costs as well as assets and liabilities directly associated with the business activity of the Company are included as a component in the financial statements. Prior to the Separation, the financial statements also included allocations of certain general, administrative, sales and marketing expenses and cost of sales from Danaher’s corporate office and from other Danaher businesses to the Company and allocations of related assets, liabilities and Danaher’s investment, as applicable. The allocations were determined on a reasonable basis; however, the amounts are not necessarily representative of the amounts that would have been reflected in the financial statements had the Company been an entity that operated independently of Danaher. Related-party allocations are discussed further in Note 23. Prior to the Separation, the Company was dependent upon Danaher for all of its working capital and financing requirements under Danaher’s centralized approach to cash management and financing of its operations. Financial transactions relating to the Company were accounted for through the Former Parent investment, net account of the Company. Accordingly, none of Danaher’s cash, cash equivalents or debt was assigned to the Company in these financial statements for the periods prior to the Separation. Former Parent investment, net, which included retained earnings, represented Danaher’s interest in the recorded net assets of the Company. Prior to the Separation, all significant transactions between the Company and Danaher have been included in the accompanying Consolidated and Combined Financial Statements. Transactions with Danaher are reflected in the accompanying Consolidated and Combined Statements of Changes in Equity as “Net transfers to Former Parent.” In connection with the Separation, the Former Parent investment, net balance was redesignated within equity and allocated between common stock and additional paid-in capital based on the number of the Company’s common shares outstanding at the Separation. In periods subsequent to the Separation, the Company may make adjustments to balances transferred at the Separation date and may record additional adjustments in the future. Any such adjustments are recorded through additional paid-in capital in equity. All significant intercompany accounts and transactions between the businesses comprising the Company have been eliminated in the accompanying Consolidated and Combined Financial Statements. Risks and Uncertainties The Company is subject to risks and uncertainties as a result of the novel coronavirus (“COVID-19”) pandemic. The extent of the impact of the COVID-19 pandemic on the Company's business is highly uncertain and difficult to predict because of the dynamic and evolving nature of the crisis. In response to COVID-19 many dental associations recommended that dental practices delay elective procedures and only perform emergency procedures. As a result, there were widespread temporary closures of dental practices around the world due to the pandemic, except to perform emergency procedures, thereby preventing the Company’s end customers from conducting most or all business activities and significantly adversely impacting the Company’s sales. During the quarter ended July 3, 2020, dental practices in the markets in which the Company operates started to reopen and as of October 2, 2020, the majority of dental practices were open. Despite the increased prevalence of COVID-19 and related U.S. and foreign government actions to mitigate the spread of COVID-19 during the quarter ended December 31, 2020, the majority of dental practices continued to remain open, however, patient volumes continued to be below pre-COVID-19 levels. A worsening of the pandemic or impacts of new variants of the virus may lead to further temporary closures of dental practices in the future. Furthermore, capital markets and economies worldwide have also been negatively impacted by the COVID-19 pandemic, and it is possible that it could cause a material local and/or global economic slowdown or global recession. Such economic disruption could have a material adverse effect on the Company as the Company’s customers curtail and reduce capital and overall spending. Policymakers around the globe have responded with fiscal policy actions to support the healthcare industry and economy as a whole. The magnitude and overall effectiveness of these actions remains uncertain. The severity of the impact of the COVID-19 pandemic on the Company's business will depend on a number of factors, including, but not limited to, the scope and duration of the pandemic, the extent and severity of the impact on the Company's customers, the measures that have been and may be taken to contain the virus (including its various mutations) and mitigate its impact, U.S. and foreign government actions to respond to the reduction in global economic activity, the ability of the Company to continue to manufacture and source its products, the impact of the pandemic and associated economic downturn on the Company’s ability to access capital if and when needed and how quickly and to what extent normal economic and operating conditions can resume, all of which are uncertain and cannot be predicted. Even after the COVID-19 pandemic has subsided, the Company may continue to experience materially adverse impacts on the Company’s financial condition and results of operations. The Company's future results of operations and liquidity could be adversely impacted by delays in payments of outstanding receivable amounts beyond normal payment terms, supply chain disruptions and uncertain demand, and the impact of any initiatives or programs that the Company may undertake to address financial and operational challenges faced by its customers. As of the date of issuance of these Consolidated and Combined Financial Statements, the extent to which the COVID-19 pandemic may materially impact the Company's financial condition, liquidity, or results of operations is uncertain. Accounting Principles —The accompanying financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”). The Consolidated and Combined Financial Statements include the accounts of the Company and its subsidiaries. The Consolidated and Combined Financial Statements also reflect the impact of noncontrolling interests. Noncontrolling interests do not have a significant impact on the Company’s consolidated results of operations, therefore income attributable to noncontrolling interests are not presented separately in the Company’s Consolidated and Combined Statements of Income. Income attributable to noncontrolling interests have been reflected in selling, general and administrative expenses and were insignificant in all periods presented. Reclassifications of certain prior year amounts have been made to conform to the current year presentation. Use of Estimates —The preparation of these financial statements requires management to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities. The Company bases these estimates on historical experience, the current economic environment and on various other assumptions that are believed to be reasonable under the circumstances. However, uncertainties associated with these estimates exist and actual results may differ materially from these estimates. Cash and Equivalents —The Company considers all highly liquid investments with a maturity of three months or less at the date of purchase to be cash equivalents. Accounts Receivable and Allowances for Credit Losses —All trade accounts receivable are reported on the accompanying Consolidated Balance Sheets adjusted for any write-offs and net of allowances for credit losses. The allowances for credit losses represent management’s best estimate of the credit losses expected from the Company’s trade accounts receivable portfolio. Determination of the allowances requires management to exercise judgment about the timing, frequency and severity of credit losses that could materially affect the provision for credit losses and, therefore, net income. The Company regularly performs detailed reviews of its portfolios to determine if an impairment has occurred and evaluates the collectability of receivables based on a combination of various financial and qualitative factors that may affect customers’ ability to pay, including customers’ financial condition, debt-servicing ability, past payment experience and credit bureau information and forecasts. In circumstances where the Company is aware of a specific customer’s inability to meet its financial obligations, a specific reserve is recorded against amounts due to reduce the recognized receivable to the amount reasonably expected to be collected. Inventory Valuation —Inventories include the costs of material, labor and overhead. Inventories are stated at the lower of cost or net realizable value primarily using the first-in, first-out method. Market value for raw materials is based on replacement costs and for other inventory classifications is based on net realizable value. The Company periodically evaluates the quantities on hand relative to current and historical selling prices and historical and projected sales volume. Based on this evaluation, provisions are made to write inventory down to its net realizable value. Property, Plant and Equipment —Property, plant and equipment are carried at cost. The provision for depreciation has been computed principally by the straight-line method based on the estimated useful lives of the depreciable assets as follows: Category Useful Life Buildings 30 years Leased assets and leasehold improvements Amortized over the lesser of the economic life of the asset or the term of the lease Machinery, equipment and other assets 3 – 10 years Estimated useful lives are periodically reviewed and, when appropriate, changes to estimates are made prospectively. Leases —The Company determines if an arrangement is a lease at inception and evaluates each lease agreement to determine whether the lease is an operating or finance lease. For leases where the Company is the lessee, ROU assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent an obligation to make lease payments arising from the lease. ROU assets and lease liabilities are recognized at the lease commencement date based on the present value of lease payments over the lease term. As most of the Company’s leases do not provide an implicit interest rate, the Company uses its incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments. The ROU asset also consists of any prepaid lease payments, lease incentives received, costs which will be incurred in exiting a lease and the amount of any asset or liability recognized on business combinations relating to favorable or unfavorable lease terms. The lease terms used to calculate the ROU asset and related lease liability include options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option. Lease expense for operating leases is recognized on a straight-line basis over the lease term as an operating expense while the expense for finance leases is recognized as depreciation expense and interest expense using the accelerated interest method of recognition. In certain of the Company’s lease agreements, the rental payments are adjusted periodically to reflect actual charges incurred for common area maintenance, utilities, inflation and/or changes in other indexes. Investments —Investments over which the Company has a significant influence but not a controlling interest, are accounted for using the equity method of accounting which requires the Company to record its initial investment at cost and adjust the balance each period for the Company’s share of the investee’s income or loss and dividends paid. No significant realized or unrealized gains or losses were recorded during the three years ended December 31, 2020 with respect to these investments. Fair Value of Financial Instruments —The Company’s financial instruments consist primarily of cash and equivalents, trade accounts receivable, nonqualified deferred compensation plans, derivatives, trade accounts payable and long-term debt. Due to their short-term nature, the carrying values for cash and equivalents, trade accounts receivable and trade accounts payable approximate fair value. Refer to Note 11 for the fair values of the Company’s other financial instruments. Goodwill and Other Intangible Assets —Goodwill and other intangible assets result from the Company’s acquisition of existing businesses. In accordance with accounting standards related to business combinations, goodwill is not amortized; however, certain finite-lived identifiable intangible assets, primarily customer relationships and acquired technology, are amortized over their estimated useful lives. Goodwill and indefinite-lived intangible assets are reviewed for impairment annually in the fourth quarter of each fiscal year or whenever an event occurs or circumstances change that would indicate that the carrying amount may be impaired. The Company elected to bypass the optional qualitative goodwill assessment allowed by applicable accounting standards and performed a quantitative impairment test for each of the Company’s reporting units. The Company’s reporting units are the financial components of operating segments which constitute businesses for which discrete financial information is available and is regularly reviewed by segment management. The Company did not record any impairment loss for goodwill or indefinite-lived intangible assets in 2020, 2019 and 2018. Management reviews the carrying amounts of other finite-lived intangible assets whenever events or circumstances indicate that the carrying amounts of an asset may not be recoverable. Impairment indicators include, among other conditions, cash flow deficits, historic or anticipated declines in revenue or operating profit, and adverse legal or regulatory developments. If it is determined that such indicators are present and the review indicates that the assets will not be fully recoverable, based on undiscounted estimated cash flows over the remaining amortization periods, their carrying values are reduced to estimated fair market value. Estimated fair market value is determined primarily using the anticipated cash flows discounted at a rate commensurate with the risk involved. For the purposes of identifying and measuring impairment, long-lived assets are grouped with other assets and liabilities at the lowest level for which identifiable cash flows are largely independent of the cash flows of other assets and liabilities. Refer to Note 8 for additional information about the Company’s goodwill and other intangible assets. Revenue Recognition —The Company derives revenues primarily from the sale of Specialty Products & Technologies and Equipment & Consumables products and services. Revenue is recognized when control of the promised products or services is transferred to the Company’s customers, in an amount that reflects the consideration the Company expects to be entitled to in exchange for those products or services (the transaction price). A performance obligation is a promise in a contract to transfer a distinct product or service to a customer and is the unit of account under ASC 606. For equipment, consumables and spare parts sold by the Company, control transfers to the customer at a point in time. To indicate the transfer of control, the Company must have a present right to payment, legal title must have passed to the customer, the customer must have the significant risks and rewards of ownership, and where acceptance is not a formality, the customer must have accepted the product or service. The Company’s principal terms of sale are FOB Shipping Point, or equivalent, and, as such, the Company primarily transfers control and records revenue for product sales upon shipment. Sales arrangements with delivery terms that are not FOB Shipping Point are not recognized upon shipment and the transfer of control for revenue recognition is evaluated based on the associated shipping terms and customer obligations. If a performance obligation to the customer with respect to a sales transaction remains to be fulfilled following shipment (typically installation or acceptance by the customer), revenue recognition for that performance obligation is deferred until such commitments have been fulfilled. Returns for products sold are estimated and recorded as a reduction of revenue at the time of sale. Customer allowances and rebates, consisting primarily of volume discounts and other short-term incentive programs, are recorded as a reduction of revenue at the time of sale because these allowances reflect a reduction in the transaction price. Product returns, customer allowances and rebates are estimated based on historical experience and known trends. For extended warranty and service, control transfers to the customer over the term of the arrangement. Revenue for extended warranty and service is recognized based upon the period of time elapsed under the arrangement. For a contract with multiple performance obligations, the Company allocates the contract’s transaction price to each performance obligation on a relative standalone selling price basis using the Company’s best estimate of the standalone selling price of each distinct product or service in the contract. The primary method used to estimate standalone selling price is the price observed in standalone sales to customers; however, when prices in standalone sales are not available the Company may use third-party pricing for similar products or services or estimate the standalone selling price. Allocation of the transaction price is determined at the contracts’ inception. The Company does not adjust transaction price for the effects of a significant financing component when the period between the transfer of the promised good or service to the customer and payment for that good or service by the customer is expected to be one year or less. Shipping and Handling —Shipping and handling costs are considered a fullfilment cost and are included as a component of cost of sales. Revenue derived from shipping and handling costs billed to customers is included in sales. Advertising —Advertising costs are expensed as incurred. Research and Development —The Company conducts research and development activities for the purpose of developing new products, enhancing the functionality, effectiveness, ease of use and reliability of the Company’s existing products and expanding the applications for which uses of the Company’s products are appropriate. Research and development costs are expensed as incurred. Income Taxes —As discussed in Note 20, for periods prior to the Separation, current income tax liabilities were assumed to be immediately settled with Danaher and were relieved through Former Parent investment, net. Income tax expense and other income tax related information contained in the Consolidated and Combined Financial Statements are presented as if the Company filed a separate tax return. The separate tax return method applies the accounting guidance for income taxes to the standalone financial statements as if the Company had been a standalone taxpayer for the periods prior to the Separation. The calculation of the Company’s income taxes on a separate income tax return basis requires considerable judgment, estimates, and allocations. Deferred tax assets and liabilities are determined based on the difference between the financial statement and tax basis of assets and liabilities using enacted rates expected to be in effect during the year in which the differences reverse. Deferred tax assets generally represent items that can be used as a tax deduction or credit in the Company’s tax return in future years for which the tax benefit has already been reflected on the Company’s Consolidated and Combined Statements of Income. The Company establishes valuation allowances for its deferred tax assets if it is more likely than not that some or all of the deferred tax assets will not be realized. Deferred tax liabilities generally represent items that have already been taken as a deduction on the Company’s tax return but have not yet been recognized as an expense in the Company’s Consolidated and Combined Statements of Income. The effect on deferred tax assets and liabilities due to a change in tax rates is recognized in income tax expense in the period that includes the enactment date. The Company provides for unrecognized tax benefits when, based upon the technical merits, it is “more likely than not” that an uncertain tax position will not be sustained upon examination. Judgment is required in evaluating tax positions and determining income tax provisions. The Company re-evaluates the technical merits of its tax positions and may recognize an uncertain tax benefit in certain circumstances, including when: (1) a tax audit is completed; (2) applicable tax laws change, including a tax case ruling or legislative guidance; or (3) the applicable statute of limitations expires. The Company recognizes potential accrued interest and penalties associated with unrecognized tax positions in income tax expense. Refer to Note 20 for additional information and discussion of the impact of the enactment of the Tax Cuts and Jobs Act (“TCJA”) in the United States. Restructuring —The Company periodically initiates restructuring activities to appropriately position the Company’s cost base relative to prevailing economic conditions and associated customer demand as well as in connection with certain acquisitions. Costs associated with productivity improvement and restructuring actions can include one-time termination benefits and related charges in addition to facility closure, contract termination and other related activities. The Company records the cost of the restructuring activities when impairment is identified or when the associated liability is incurred. Refer to Note 19 for additional information. Foreign Currency Translation —Exchange rate adjustments resulting from foreign currency transactions are recognized in net income, whereas effects resulting from the translation of financial statements are reflected as a component of accumulated other comprehensive loss within equity. Assets and liabilities of subsidiaries operating outside the United States with a functional currency other than U.S. dollars are translated into U.S. dollars using year-end exchange rates and income statement accounts are translated at weighted average rates. Net foreign currency transaction gains or losses were not material in any of the years presented. In September 2019, the Company entered into cross-currency swap arrangements whereby existing U.S. dollar-denominated borrowings were effectively converted to foreign currency borrowings to partially hedge additional amounts of its net investments in foreign operations against adverse movements in exchange rates. Refer to Note 10 for additional information. Derivative Financial Instruments —The Company is neither a dealer nor a trader in derivative instruments. The Company has generally accepted the exposure to transactional exchange rate movements without using derivative instruments to manage this risk, although the Company from time to time partially hedges its net investments in foreign operations against adverse movements in exchange rates through foreign currency-denominated debt and cross-currency swaps. The Company has entered into interest rate swaps to mitigate a portion of its interest rate risk related to the Company’s debt as further discussed in Note 10. The derivative instruments are recorded on the Consolidated Balance Sheets as either an asset or liability measured at fair value. To the extent the interest rate swap qualifies as an effective hedge, changes in fair value are recognized in accumulated other comprehensive loss within equity. Changes in the value of the foreign currency denominated debt and cross-currency swaps designated as hedges of the Company’s net investment in foreign operations based on spot rates are recognized in accumulated other comprehensive loss within equity and offset changes in the value of the Company’s foreign currency denominated operations. Refer to Note 10 for additional information. Loss Contingencies —The Company records a reserve for loss contingencies when it is both probable that a loss will be incurred and the amount of the loss is reasonably estimable. The Company evaluates pending litigation and other contingencies at least quarterly and adjusts the reserve for such contingencies for changes in probable and reasonably estimable losses. Accumulated Other Comprehensive Loss —Foreign currency translation adjustments are generally not adjusted for income taxes as they relate to indefinite investments in non-U.S. subsidiaries. Foreign currency translation adjustments related to the Company’s cross-currency swap arrangements and foreign currency denominated debt that are designated as net investment hedges are adjusted for income taxes as those arrangements are not indefinite. Accounting for Stock-Based Compensation —The Company accounts for stock-based compensation by measuring the cost of employee services received in exchange for all equity awards granted, including stock options, restricted stock units (“RSUs”) and performance stock units (“PSUs”), based on the fair value of the award as of the grant date. Equity-based compensation expense is recognized net of an estimated forfeiture rate on a straight-line basis over the requisite service period of the award, except that in the case of RSUs, compensation expense is recognized using an accelerated attribution method. Refer to Note 16 for additional information on the stock-based compensation plan in which certain employees of the Company participate. Pension Plans —The Company measures its pension assets and obligations that determine the funded status as of the end of the Company’s fiscal year, and recognizes an asset for an overfunded status or a liability for an underfunded status in its Consolidated Balance Sheets. Changes in the funded status of the pension plans are recognized in the year in which the changes occur and reported in other comprehensive income (loss). Refer to Note 12 for additional information on the Company’s pension plans including a discussion of the actuarial assumptions, the Company’s policy for recognizing the associated gains and losses and the method used to estimate service and interest cost components. Accounting Standards Recently Adopted —In December 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes, which is intended to simplify various aspects related to accounting for income taxes. ASU 2019-12 removes certain exceptions to the general principles in Topic 740 and also clarifies and amends existing guidance to improve consistent application. The ASU is effective for public entities for fiscal years beginning after December 15, 2020, with early adoption permitted. The Company adopted this guidance on January 1, 2021, and is in the process of completing its assessment. However, the Company does not expect it to have a material impact on its Consolidated and Combined Financial Statements. In August 2018, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2018-13, Fair Value Measurement (Topic 820), which modified the disclosures on fair value measurements by removing the requirement to disclose the amount and reasons for transfers between Level 1 and Level 2 of the fair value hierarchy and the policy for timing of such transfers. The ASU expands the disclosure requirements for Level 3 fair value measurements, primarily focused on changes in unrealized gains and losses included in other comprehensive income (loss). The Company adopted this guidance on January 1, 2020, which did not have a significant impact on the Company’s Consolidated and Combined Financial Statements. In August 2018, the FASB issued ASU No. 2018-14, Disclosure Framework — Changes to the Disclosure Requirements for Defined Benefit Plans , which amends Accounting Standards Codification (“ASC”) 715 to add, remove, and clarify disclosure requirements related to defined benefit pension plans. The ASU is effective for public entities for fiscal years ending after December 15, 2020, with early a |
