Accounting Policies [Abstract] |
Use of Estimates | The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America (“US GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities as of the date of the financial statements and the reported amounts of revenue and expense during the reporting period. Actual results could differ materially from those estimates. Specifically, for the year ended December 31, 2020, some of these estimates and assumptions were based on the potential impacts of the COVID-19 pandemic. The full extent to which the COVID-19 pandemic will directly or indirectly have a negative material impact on the Company's financial condition, liquidity, or results of operations, is highly uncertain and difficult to predict. More specifically, the demand for the Company's products has been, and continues to be, affected by social distancing guidelines, newly implemented dental practice safety protocols which reduce patient traffic, and patient reluctance to seek dental care. At this time, it is uncertain how long these impacts will continue. During the year the Company's business was impacted by COVID-19. The impact began in the early part of the first quarter as the Company began to experience declines in customer demand in Asia and then further in mid-March where it was most pronounced in Europe and where the Company experienced partial or country-wide business lockdowns in various markets, including China, France, and Italy. The United States was most impacted in April and May. Most regions throughout the world continue to experience localized surges of COVID-19 cases which are being responded to by governmental authorities with partial lockdowns. While the duration and severity of this continuing p andemic is uncertain, the Company currently expects that the COVID-19 pandemic may have a negative impact on its operations in 2021. As a result of the economic uncertainties caused by the COVID-19 pandemic, the Company implemented several measures to improve liquidity and operating results, including reduction of employee hours and salaries, furloughs, suspended hiring, travel bans, delaying some of its planned capital expenditures, and deferring other discretionary spending for 2020. Many of these measures have been eased during the second half of the year as demand for the Company's products has improved. The Company continues to monitor the COVID-19 pandemic and may need to reduce operations in the event of a resurgence of COVID-19 or in the event of actions from governmental authorities to combat a resurgence. The Company believes it will be able to generate sufficient liquidity to satisfy its obligations and remain in compliance with the Company's existing debt covenants for the next twelve months. At December 31, 2020, the Company's liquidity includes $438 million of cash and has access to a $700 million 2018 Credit Facility as well as other short-term credit facilities of approximately $400 million. (See Note 13, Financing Arrangements). At December 31, 2020, the Company is in compliance with all of its debt covenants and expects to remain in compliance with all covenants for the next twelve months. However, if recovery from the pandemic takes longer than currently estimated, the Company may not be able to comply with its debt covenants and may have to seek covenant waivers. Inability to obtain debt covenant waivers may lead to default and acceleration of all of its outstanding debt, which could have a material adverse effect on liquidity.
Principles of Presentation | Basis of Presentation The consolidated financial statements include the results of the Company and its wholly-owned subsidiaries. All significant intercompany accounts and transactions are eliminated in consolidation. For the year ended December 31, 2020, amounts recorded in the Consolidated Statements of Operations and Consolidated Statements of Comprehensive Income reflect certain adjustments pertaining to prior periods, the impact of which are not material to the financial statements for the years presented. These corrections, which primarily include adjustments to accruals recorded through cost of products sold and selling, general, and administrative expenses, resulted in a net $9 million and $7 million decrease to pre-tax income and net income, respectively, in the twelve months ended December 31, 2020. Investments in non-consolidated affiliates, joint ventures and partnerships where the Company maintains significant influence over an entity are accounted for using the equity method.
Cash and Cash Equivalents | Cash and cash equivalents include deposits with banks as well as highly liquid time deposits with original maturities of ninety days or less.
Short-term Investments | Short-term investments are highly liquid time deposits with original maturities greater than ninety days and with remaining maturities of one year or less.
Accounts and Notes Receivable-Trade | The Company establishes an allowance for doubtful accounts based on an estimate of current expected credit losses resulting from the inability of its customers to make required payments. The allowance is determined based on a combination of factors, including the length of time that the receivable is past due, history of write-offs, and the Company's knowledge of circumstances relating to specific customers' ability to meet their financial obligations. Provision for doubtful accounts are included in Selling, General and Administrative expenses in the Consolidated Statements of Operations. For customers on credit terms, the Company performs ongoing credit evaluation of those customers’ financial condition and generally does not require collateral from them.
Inventories | Inventories are stated at the lower of cost and net realizable value. The cost of inventories is based upon the First In First Out Method ("FIFO") or average cost methods, except for $3 million and $5 million of inventories was determined by the last-in, first-out (“LIFO”) method as of December 31, 2020 and 2019, respectively. If the FIFO method had been used to determine the cost of LIFO inventories, the amounts at which net inventories are stated would be higher than reported at December 31, 2020 and 2019 by $22 million and $14 million, respectively. The Company establishes reserves for inventory estimated to be excess, obsolete or unmarketable based upon assumptions about future demand, market conditions, and expiration of products.
Valuation of Goodwill and Indefinite-Lived Intangible Assets | Assessment of the potential impairment of goodwill and indefinite-lived and definite-lived intangible assets is an integral part of the Company’s normal ongoing review of operations. Testing for potential impairment of these assets is significantly dependent on assumptions and reflects management’s best estimates at a particular point in time. The dynamic economic environments in which the Company’s businesses operate and key economic and business assumptions with respect to projected selling prices, increased competition and introductions of new technologies can significantly affect the outcome of impairment tests. Estimates based on these assumptions may differ significantly from actual results. Changes in factors and assumptions used in assessing potential impairments can have a significant impact on the existence and magnitude of impairments, as well as the time at which such impairments are recognized. If there are unfavorable changes in these assumptions, future cash flows, a key variable in assessing the impairment of these assets, may decrease and as a result the Company may be required to recognize impairment charges. Future changes in the environment and the economic outlook for the assets being evaluated could also result in additional impairment charges being recognized. The following information outlines the Company’s significant accounting policies on long-lived assets by type. Goodwill Goodwill is the excess of the purchase price over the fair value of identifiable net assets acquired and liabilities assumed in a business combination. Goodwill is not amortized. The Company conducts an impairment test as of April 30 of each year, or more frequently if events or circumstances indicate that the carrying value of goodwill may be impaired. This impairment assessment includes an evaluation of reporting units, which the Company has determined are either an operating segment or one level below its operating segments, as determined in accordance with ASC 350. The Company performs impairment tests by comparing the fair value of each reporting unit to its carrying amount to determine if there is a potential impairment. If the carrying value of a reporting unit with goodwill exceeds its fair value, an impairment charge is recognized for the excess amount. To determine the fair value of the Company’s reporting units, the Company uses a discounted cash flow model as its valuation technique to measure the fair value for its reporting units. The discounted cash flow model uses five- to ten-year forecasted cash flows plus a terminal value based on a multiple of earnings or by capitalizing the last period’s cash flows using a perpetual growth rate. The Company's significant assumptions in the discounted cash flow models include, but are not limited to, the discount rates, revenue growth rates, perpetual revenue growth rates, and operating margin percentages of the reporting unit's business. The Company considers the current market conditions when determining its assumptions. Lastly, the Company reconciles the aggregate fair values of its reporting units to its market capitalization, which include a reasonable control premium based on market conditions. Additional information related to the testing for goodwill impairment including results of the annual test performed at April 30, 2020 is provided in Note 10, Goodwill and Intangible Assets. Indefinite-Lived Intangible Assets Indefinite-lived intangible assets consist of tradenames and trademarks acquired during business combinations, and these are not subject to amortization. Valuations of indefinite life intangibles assets acquired are based on information and assumptions available at the time of their acquisition, using income and market approaches to determine fair value. The Company conducts an impairment test as of April 30 of each year, or more frequently if events or circumstances indicate that the carrying value of indefinite-lived intangible assets may be impaired. Potential impairment is identified by comparing the fair value of an intangible asset to its carrying value. The Company performs impairment tests using an income approach, more specifically a relief from royalty method. In the development of the forecasted cash flows, the Company applies significant judgment to determine key assumptions, including revenue growth rates, perpetual revenue growth rates, royalty rates, and discount rates. If the carrying value exceeds the fair value, an impairment loss in the amount equal to the excess is recognized. Additional information related to the testing for indefinite-lived intangible asset impairment including results of the annual test performed at April 30, 2020 is provided in Note 10, Goodwill and Intangible Assets. Definite-Lived Intangible Assets Definite-lived intangible assets primarily consist of patents, tradenames, trademarks, licensing agreements, technology know-how, and customer relationships. Valuation of definite-lived intangibles assets acquired in business combinations are based on information and assumptions available at the time of acquisition, using income and market model approaches to determine fair value. Identifiable definite-lived intangible assets are amortized on a basis that best reflects how their economic benefits are utilized over the life of the asset or on a straight-line basis if not materially different from actual utilization. The useful life is the period over which the asset is expected to contribute to the future cash flows of the Company. The Company uses the following useful lives for its definite-lived intangible assets:
Definite-lived Intangible Asset Type |  | Useful Life
Patents |  | Up to date patent expires
Tradenames and trademarks |  | Up to 20 years
Licensing agreements |  | Up to 20 years
Customer relationships |  | Up to 15 years
Technology know-how |  | Up to 10 years
When the expected useful life of an intangible is not known, the Company will estimate its useful life based on similar asset or asset groups, any legal, regulatory, or contractual provision that limits the useful life, the effect of economic factors, including obsolescence, demand, competition, and the level of maintenance expenditures required to obtain the expected future economic benefit from the asset. These assets are reviewed for impairment whenever events or circumstances suggest that the carrying amount of the asset may not be recoverable. The Company closely monitors all intangible assets including those related to new and existing technologies for indicators of impairment as these assets have more risk of becoming impaired. Impairment is based upon an initial evaluation of the identifiable undiscounted cash flows. If the initial evaluation identifies a potential impairment, a fair value of the asset is determined by using a discounted cash flows valuation. If impaired, the resulting charge reflects the excess of the asset’s carrying cost over its fair value.
Property, Plant and Equipment | Property, plant and equipment are stated at cost, net of accumulated depreciation. Assets acquired through acquisitions are recorded at fair value. Except for leasehold improvements, depreciation is computed by the straight-line method over the assets' estimated useful lives:
Property, Plant, and Equipment Assets Type |  | Useful Life
Buildings | 40 years
Machinery and Equipment | 4 to 15 years
Leasehold Improvements | Shorter of the estimated useful life or the term of the lease
Maintenance and repairs are expensed as incurred; replacements and major improvements are capitalized. If events or circumstances exist which suggest that the carrying amount of the asset group may not be recoverable the asset group is reviewed for impairment whenever impairment is calculated based upon an evaluation of the identifiable undiscounted cash flows as compared to the carrying value of the asset. If impaired, the resulting charge reflects the excess of the asset group’s carrying cost over its fair value.
Leases | In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) with subsequent amendments (collectively, “ASC 842”). The Company adopted the new leasing standards on January 1, 2019 using the modified retrospective approach transition method. Results for reporting periods beginning after January 1, 2019 are presented under ASC 842, while prior periods are not adjusted and continue to be reported in accordance with historic accounting under ASC 840. The Company elected the package of practical expedients permitted under the transition guidance within the standard, which eliminates the reassessment of past leases, their classification and initial direct costs for existing leases. The Company did not elect to adopt the hindsight practical expedient. The Company recognized material right-of-use assets and liabilities in the Consolidated Balance Sheets for its operating lease commitments with terms greater than 12 months.
Derivative Financial Instruments | The Company employs derivative financial instruments to hedge certain anticipated transactions, firm commitments, and assets and liabilities denominated in foreign currencies. Additionally, the Company utilizes interest rate swaps to convert floating rate debt to fixed rate. The Company records all derivative instruments at fair value and changes in fair value are recorded each period in the consolidated statements of operations or accumulated other comprehensive income (“AOCI”). The Company classifies derivative assets and liabilities as current when the remaining term of the derivative contract is one year or less. The Company has elected to classify the cash flow from derivative instruments in the same category as the cash flows from the items being hedged. Should the Company enter into a derivative instrument that included an other-than-insignificant financing element then all cash flows will be classified as financing activities in the Consolidated Statements of Cash Flows as required by US GAAP.
Pension and Other Postemployment Benefits | Some of the employees of the Company and its subsidiaries are covered by government or Company-sponsored defined benefit plans and defined contribution plans. Additionally, certain union and salaried employee groups in the United States are covered by postemployment healthcare plans. Costs for Company-sponsored defined benefit and postemployment benefit plans are based on expected return on plan assets, discount rates, employee compensation increase rates and health care cost trends. Expected return on plan assets, discount rates and health care cost trend assumptions are particularly important when determining the Company’s benefit obligations and net periodic benefit costs associated with postemployment benefits. Changes in these assumptions can impact the Company’s earnings. In determining the cost of postemployment benefits, certain assumptions are established annually to reflect market conditions and plan experience to appropriately reflect the expected costs as actuarially determined. These assumptions include medical inflation trend rates, discount rates, employee turnover and mortality rates. The Company predominantly uses liability durations in establishing its discount rates, which are observed from indices of high-grade corporate bond yields in the respective economic regions of the plans. The expected return on plan assets is the weighted average long-term expected return based upon asset allocations and historic average returns for the markets where the assets are invested, principally in foreign locations. The Company reports the funded status of its defined benefit pension and other postemployment benefit plans on its consolidated balance sheets as a net liability or asset.
Accruals for Self-Insured Losses | The Company maintains insurance for certain risks, including workers’ compensation, and is self-insured for employee related healthcare benefits. The Company accrues for the expected costs associated with these risks by considering historical claims experience, demographic factors, severity factors and other relevant information. Costs are recognized in the period the claim is incurred, and the financial statement accruals include an estimate of claims incurred but not yet reported. The Company has stop-loss coverage to limit its exposure to any significant exposure on a per claim basis.
Litigation | The Company and its subsidiaries, from time to time, are parties to lawsuits arising from operations. The Company records liabilities when a loss is probable and can be reasonably estimated. If these estimates are in the form of ranges, the Company records the liabilities at the most likely outcome within the range. If no point within the range represents a better estimate of the probable loss, then the low point in the range is accrued. The ranges established by management are based on analysis made by internal and external legal counsel who considers information known at the time. If the Company determines that a contingency is reasonably possible, it considers the same information to estimate the possible exposure and discloses any material potential liability. These loss contingencies are monitored regularly for a change in fact or circumstance that would require an accrual adjustment. The Company believes it has estimated liabilities for probable losses appropriately in the past; however, the unpredictability of litigation and court decisions could cause a liability to be incurred in excess of estimates. Legal costs related to these lawsuits are expensed as incurred.
Foreign Currency Translation | The functional currency for foreign operations, except for those in highly inflationary economies, generally has been determined to be the local currency. Assets and liabilities of foreign subsidiaries are translated at foreign exchange rates on the balance sheet date; revenue and expenses are translated at the average year-to-date foreign exchange rates. The effects of these translation adjustments are reported in Equity within AOCI in the Consolidated Balance Sheets. During the year ended December 31, 2020, the Company had losses of $54 million on its loans designated as hedges of net investments and translation gains of $235 million. During the year ended December 31, 2019, the Company had gains of $4 million on its loans designated as hedges of net investments and translation losses of $87 million. Foreign currency gains and losses arising from transactions denominated in a currency other than the functional currency of the entity involved and remeasurement adjustments in countries with highly inflationary economies are included in income.
Revenue Recognition | Revenue Recognition Revenue is measured as the amount of consideration the Company expects to receive in exchange for transferring goods or providing services. Revenue is recognized when performance obligations under the terms of a contract with a customer are satisfied; generally this occurs with the transfer of risk and/or control of products to its customers. Sales, value-added, and other taxes collected concurrent with revenue-producing activities are excluded from revenue. For most of consumable, technology, and equipment products, the Company transfers control and recognizes revenue when products are shipped from the Company's manufacturing facility or warehouse to the customer (distributors and direct to dentists). For contracts with customers that contain destination shipping terms, revenue is not recognized until risk has transferred and the goods are delivered to the agreed upon destination. The amount of consideration received and revenue recognized varies with changes in marketing incentives (e.g. discounts, rebates, free goods) and returns offered to customers and their customers. When the Company gives customers the right to return eligible products and receive credit, returns are estimated based on an analysis of historical experience. However, returns of products, excluding warranty-related returns, are infrequent and insignificant. The Company adjusts the estimate of revenue at the earlier of when the most likely amount of consideration can be estimated, the amount expected to be received changes, or when the consideration becomes fixed. Consideration received from customers in advance of revenue recognition is classified as deferred revenue. Depending on the terms of the arrangement, the Company may also defer the recognition of a portion of revenue on a relative stand-alone selling price basis when performance obligations are not yet satisfied (e.g., free extended maintenance/service contracts, software and licenses, customer loyalty points and coupon programs). The Company uses an observable price, typically average selling price, to determine the stand-alone selling price for separate performance obligations. The Company determines the stand-alone selling price, based on Company geographic sales locations' database of pricing and discounting practices for the specific product or service when sold separately, and utilizes this data to arrive at average selling prices by product. Revenue is then allocated proportionately, based on the determined stand-alone selling price, to the unsatisfied performance obligation, which is deferred until satisfied. At December 31, 2020, the Company had $41 million of deferred revenue recorded in Accrued liabilities in the Consolidated Balance Sheets. The Company expects to recognize significantly all of the deferred revenue within the next twelve months. The prior year amount of $29 million was recognized in the current year. The Company has elected to account for shipping and handling activities as a fulfillment cost within the cost of products sold, and records shipping and handling costs collected from customers in net sales. The Company has adopted two practical expedients: the “right to invoice” practical expedient, which allows us to recognize revenue in the amount of the invoice when it corresponds directly with the value of performance completed to date; and relief from considering the existence of a significant financing component when the payment for the good or service is expected to be one year or less. The Company offers discounts to its customers and distributors if certain conditions are met. Discounts are primarily based on the volume of products purchased or targeted to be purchased by the customer or distributor. Discounts are deducted from revenue at the time of sale or when the discount is offered, whichever is later. The Company estimates volume discounts based on the individual customer’s or distributor's historical and estimated future product purchases. Certain of the Company’s customers are offered cash rebates based on targeted sales increases. The Company estimates rebates based on the forecasted performance of a customer and their expected level of achievement within the rebate programs. In accounting for these rebate programs, the Company records an accrual and reduces net sales ratably as sales occur over the rebate period. The Company updates the accruals for these rebate programs as actual results and updated forecasts impact the estimated achievement for customers within the rebate programs. A portion of the Company’s net sales is comprised of sales of precious metals generated through its precious metal dental alloy product offerings. As the precious metal content of the Company’s sales is largely a pass-through to customers, the Company uses its cost of precious metal purchased as a proxy for the precious metal content of sales, as the precious metal content of sales is not separately tracked and invoiced to customers. The Company believes that it is reasonable to use the cost of precious metal content purchased in this manner since precious metal alloy sale prices are typically adjusted when the prices of underlying precious metals change.
Cost of Products Sold | Cost of products sold represents costs directly related to the manufacture and distribution of the Company’s products. Primary costs include raw materials, packaging, direct labor, overhead, shipping and handling, warehousing and the depreciation of manufacturing, warehousing and distribution facilities. Overhead and related expenses include salaries, wages, employee benefits, utilities, lease costs, maintenance and property taxes.
Warranties | The Company provides warranties on certain equipment products. Estimated warranty costs are accrued when sales are made to customers. Estimates for warranty costs are based primarily on historical warranty claim experience. Warranty costs are included in Cost of products sold in the Consolidated Statements of Operations.
Selling, General and Administrative Expenses | Selling, general and administrative expenses represent indirect costs associated with generating revenues and in managing the business of the Company. Such costs include advertising and other marketing expenses, salaries, employee benefits, incentive compensation, research and development, travel, office expenses, lease costs, amortization of capitalized software and depreciation of administrative facilities. Advertising cost are expensed as incurred.
Research and Development Costs | Research and development (“R&D”) costs relate primarily to salaries and direct overhead expenses associated with R&D activities. In addition, the Company contracts with outside vendors to conduct R&D activities. All such R&D costs are charged to expense when incurred. The Company capitalizes the costs of equipment that have general R&D uses and expenses such equipment that is solely for specific R&D projects. The depreciation expense related to this capitalized equipment is included in the Company’s R&D costs. Software development costs related to software to be sold, leased, or otherwise marketed incurred prior to the attainment of technological feasibility are considered R&D and are expensed as incurred. Once technological feasibility is established, software development costs are capitalized until the product is available for general release to customers. Amortization of these costs are included in Cost of products sold over the estimated life of the products. R&D costs were $115 million, $131 million and $161 million for the years ended December 31, 2020, 2019 and 2018, respectively, and are included in Selling, general and administrative expenses in the Consolidated Statements of Operations.
Stock Compensation | Stock-based compensation is measured at the grant date, fair value, and is recognized as an expense over the employee’s requisite service period (generally the vesting period of the equity awards). The compensation cost is only recognized for the portion of the awards that are expected to vest. Stock options granted become exercisable as determined by the grant agreement and expire ten years after the date of grant under these plans. Restricted Stock Units ("RSU") vest as determined by the grant agreement and are subject to a service condition, which requires grantees to remain employed by the Company during the period following the date of grant. Under the terms of the RSUs, the vesting period is referred to as the restricted period. In addition to the service condition, certain granted RSUs are subject to performance requirements that can vary between the first year and up to the final year of the RSU award. If targeted performance is not met the RSU granted is adjusted to reflect the achievement level. Upon the expiration of the applicable restricted period and the satisfaction of all conditions imposed, the restrictions on RSUs will lapse, and shares of common stock will be issued as payment for each vested RSU. Upon death, disability or qualified retirement all awards become immediately exercisable for up to one year. Awards are expensed as compensation over their respective vesting periods or to the eligible retirement date if shorter. The Company records forfeitures on stock-based compensation as the participant terminates rather than estimating forfeitures. During 2019, the Company granted certain performance-based RSUs issued under the 2016 Omnibus Incentive Plan to provide performance targets for the Company's previously disclosed three year restructuring program announced in November 2018. The adjusted operating income margin performance target approximates the adjusted operating income margin targets previously disclosed by the Company as part of its effort to support revenue growth and margin expansion. For vesting to occur an adjusted operating income margin target must be achieved over a period of four consecutive quarters, and an adjusted operating income margin above that target threshold as measured at the end of the subsequent quarter, all calculated on a trailing four quarter basis. The performance period began on January 1, 2019 and concludes on December 31, 2022. Under this program the Company could issue up to 3 million shares of common stock if all performance targets are met within the period. See Note 14 Equity for more information.
Income Taxes | The Company’s tax expense includes U.S. and international income taxes plus the provision for U.S. taxes on undistributed earnings of international subsidiaries not deemed to be permanently invested. Tax credits and other incentives reduce tax expense in the year the credits are claimed. Certain items of income and expense are not reported in tax returns and financial statements in the same year. The tax effect of such temporary differences is reported as deferred income taxes. Deferred tax assets are recognized if it is more likely than not that the assets will be realized in future years. The Company establishes a valuation allowance for deferred tax assets for which realization is not likely. The Company applies a recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. The Company recognizes in the consolidated financial statements the impact of a tax position if that position is more likely than not of being sustained upon examination by the taxing authorities based on the technical merits of the position. The Company’s tax positions are subject to ongoing examinations by the tax authorities. The Company operates within multiple taxing jurisdictions throughout the world and in the normal course of business is examined by taxing authorities in those jurisdictions. Adjustments to the uncertain tax positions are recorded when taxing authority examinations are completed, statutes of limitation are closed, changes in tax laws occur or as new information comes to light with regard to the technical merits of the tax position.
Earnings Per Share | Basic earnings per share are calculated by dividing net earnings attributable to Company’s shareholders by the weighted average number of shares outstanding for the period. Diluted earnings per share is calculated by dividing net earnings attributable to Company’s shareholders by the weighted average number of shares outstanding for the period, adjusted for the effect of an assumed exercise of all dilutive options outstanding at the end of the period, unless the impact of including these options is anti-dilutive.
Business Acquisitions | The Company acquires businesses as well as partial interests in businesses. Acquired businesses are accounted for using the acquisition method of accounting which requires the Company to record assets acquired and liabilities assumed at their respective fair values with the excess of the purchase price over estimated fair values recorded as goodwill. The assumptions made in determining the fair value of acquired assets and assumed liabilities as well as asset lives can materially impact the results of operations. The Company obtains information during due diligence and through other sources to establish respective fair values. Examples of factors and information that the Company uses to determine the fair values include: tangible and intangible asset valuations and appraisals, and evaluations of existing contingencies, liabilities, and product line information. If the initial valuation for an acquisition is incomplete by the end of the reporting period in which the acquisition occurred, the Company will record a provisional estimate in the financial statements. The provisional estimate will be finalized as soon as information becomes available, but will only occur up to one year from the acquisition date. If the subsequent actual results and updated projections of the underlying business activity change compared with the assumptions and projections used to develop these values, we could record impairment charges. On December 31, 2020, the Company acquired Straight Smile LLC ("Byte"), a leading provider in the direct-to-consumer, doctor-directed clear aligner market. The Company acquired all of the outstanding membership interests of Byte for total cash consideration of approximately $1.0 billion. The purchase price allocation resulted in the recording of $631 million of goodwill and $416 million of amortizable intangible assets, including tradenames, technology know-how, and non-compete agreements. The Company values identified intangible assets using an income approach. Technology know-how is valued using an excess earnings method. Tradename and trademark assets are valued using a relief-from-royalty method. Non-compete agreements are valued using a with-and-without method. The Company applied significant judgment in estimating the fair value of intangible assets acquired, which involved the use of significant estimates and assumptions with respect to revenue growth rates, EBITDA margin percentages, royalty rate, technology obsolescence factors, useful lives of the assets and discount rates used in computing present values. In addition, the estimates of useful lives of these acquired intangibles are used to calculate depreciation and amortization expense. If the estimates of the economic lives change, depreciation or amortization expenses could be increased or decreased, or the acquired asset could be impaired. For additional information related to accounting for acquisitions, see Note 4, Business Combinations.
Noncontrolling Interests | The Company reports noncontrolling interest (“NCI”) in a subsidiary as a separate component of Equity in the Consolidated Balance Sheets. Additionally, the Company reports the portion of net income (loss) and comprehensive income (loss) attributed to the Company and NCI separately in the Consolidated Statements of Operations.
Segment Reporting | The Company has numerous operating businesses covering a wide range of products and geographic regions, primarily serving the professional dental market and to a lesser extent the consumable medical device market. The Company has two reportable segments and a description of the activities within these segments is included in Note 5, Segment and Geographic Information.
Fair Value Measurement | Recurring Basis The Company records certain financial assets and liabilities at fair value in accordance with the accounting guidance, which defines fair value as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date in current markets. The accounting guidance establishes a hierarchical disclosure framework associated with the level of pricing observability utilized in measuring financial instruments at fair value. The three broad levels defined by the fair value hierarchy are as follows: Level 1 - Quoted prices are available in active markets for identical assets or liabilities as of the reported date. Level 2 - Pricing inputs are other than quoted prices in active markets, which are either directly or indirectly observable as of the reported date. These financial instruments include derivative instruments whose fair value have been derived using a model where inputs to the model are directly observable in the market or can be derived principally from, or corroborated by observable market data. Level 3 - Instruments that have little to no pricing observability as of the reported date. These financial instruments do not have two-way markets and are measured using management’s best estimate of fair value, where the inputs into the determination of fair value require significant management judgment or estimation. The degree of judgment utilized in measuring the fair value of certain financial assets and liabilities generally correlates to the level of pricing observability. Pricing observability is impacted by a number of factors, including the type of financial instrument. Financial assets and liabilities with readily available active quoted prices or for which fair value can be measured from actively quoted prices generally will have a higher degree of pricing observability and a lesser degree of judgment utilized in measuring fair value. Conversely, financial assets and liabilities rarely traded or not quoted will generally have less, or no pricing observability and a higher degree of judgment utilized in measuring fair value. The Company primarily applies the market approach for recurring fair value measurements and endeavors to utilize the best available information. Accordingly, the Company utilizes valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs. Additionally, the Company considers its credit risks and its counterparties’ credit risks when determining the fair values of its financial assets and liabilities. The Company records its derivatives and contingent considerations on a recurring fair value basis. The Company believes the carrying amounts of cash and cash equivalents, accounts receivable (net of allowance for doubtful accounts), prepaid expenses and other current assets, accounts payable, accrued liabilities, income taxes payable and notes payable approximate fair value due to the short-term nature of these instruments. The Company has presented the required disclosures in Note 19, Fair Value Measurement. Non-Recurring Basis When events or circumstances require an asset or liability to be measured at fair valued that otherwise is generally recorded based on another valuation method, such as, net realizable value, the Company will utilize the valuation techniques described above. The Company records its business combinations and impairments on a non-recurring basis.
Recently Adopted Accounting Pronouncements and Accounting Standards Not Yet Adopted | Recently Adopted Accounting Pronouncements In June 2016, the FASB issued ASU No. 2016-13 "Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments." This newly issued accounting standard changes the recognition and measurement of credit losses, including trade accounts receivable. Under current accounting standards, a loss is recognized when loss becomes probable of occurring. The new standard broadens the information that an entity must consider when developing expected credit loss estimates.
