SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	12 Months Ended
Oct. 01, 2021
Accounting Policies [Abstract]
Basis of Presentation	The accompanying consolidated financial statements have been prepared by the Company pursuant to the rules and regulations of the SEC and prepared in accordance with accounting principles generally accepted in the United States ("GAAP"). The Company has consolidated all the majority owned subsidiaries and entities over which we have control. All intercompany balances and transactions have been eliminated in consolidation.
Segment Reporting	Segment Reporting The Company has two reportable operating segments; (i) Medical and (ii) Industrial.
Fiscal Year	Fiscal Year The fiscal years of the Company as reported are the 52 or 53-week period ending on the Friday nearest September 30. Fiscal year 2021 was the 52-week period that ended October 1, 2021, fiscal year 2020 was the 53-week period that ended October 2, 2020, and fiscal year 2019 was the 52-week period that ended September 27, 2019.
Variable Interest Entities	Variable Interest Entities For entities in which the Company has variable interests, the Company focuses on identifying which entity has the power to direct the activities that most significantly impact the variable interest entity’s economic performance and which entity has the obligation to absorb losses or the right to receive residual returns from the variable interest entity. If the Company is the primary beneficiary of a variable interest entity, the assets, liabilities and results of operations of the variable interest entity will be included in the Company’s consolidated financial statements. As of October 1, 2021, the Company had variable interests in two entities, neither of which were consolidated by the Company.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting periods. Such estimates include the valuation of inventories, valuation of goodwill and intangible assets, warranties, contract liabilities, long-lived asset valuations, impairment on investments, valuation of financial instruments, and taxes on income. Actual results could differ from these estimates.
Cash and Cash Equivalents and Restricted Cash	Cash and Cash Equivalents The Company considers currency on hand, demand deposits, time deposits and all highly-liquid investments with an original maturity of three months or less at the date of purchase to be cash and cash equivalents. Restricted Cash Restricted cash primarily consists of cash collateral related to certain leases and inventory arrangements. Restricted cash is included in other assets on the consolidated balance sheets.
Fair Value	Fair Value Fair value is defined 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 at the measurement date. There is a three-level fair value hierarchy that prioritizes the inputs used to measure fair value. This hierarchy requires entities to maximize the use of observable inputs and minimize the use of unobservable inputs. The three levels of inputs used to measure fair value are as follows: Level 1—Quoted prices in active markets for identical assets or liabilities. Level 2—Observable inputs other than quoted prices included in Level 1, such as quoted prices for similar assets and liabilities in active markets; quoted prices for identical or similar assets and liabilities in markets that are not active; or, other inputs that are observable or can be corroborated by observable market data. Level 3—Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.
Derivative instruments and hedging activities	Derivative instruments and hedging activities The Company records all derivatives on the consolidated balance sheets at fair value as of the reporting date. For derivative instruments that are designated and qualify as cash flow hedges, the gain or loss on the derivative is reported as a component of other comprehensive income or loss and reclassified from accumulated other comprehensive income into earnings when the hedged transaction affects earnings. For derivatives that are designated and qualify as net investment hedges, the gain or loss on the derivative is reported as a component of other comprehensive income or loss until the hedged item is sold. The portion of the change in fair value of the Company's net investment hedges (or cross currency swaps) related to the cross-currency basis spread is an excluded component in the assessment of the effectiveness of these net investment hedges (or cross currency swaps). A qualitative assessment of hedge effectiveness is performed on a quarterly basis, unless facts and circumstances indicate the hedge may no longer be highly effective, in which case, a quantitative assessment of hedge effectiveness is performed.
Concentration of Risk	Concentration of Risk Financial instruments that potentially expose the Company to concentrations of credit risk consist principally of cash, cash equivalents and trade accounts receivable. Cash held with financial institutions may exceed the Federal Deposit Insurance Corporation insurance limits or similar limits in foreign jurisdictions. The Company has not experienced any losses on its deposits of cash and cash equivalents. The Company performs ongoing credit evaluations of its customers and, except for government tenders, group purchases and orders with a letter of credit, its industrial customers often provide a down payment. The Company maintains an allowance for doubtful accounts based upon the expected collectability of all accounts receivable. The Company obtains some of the components in its products from a limited group of suppliers or from a single-source supplier.
Inventories	Inventories Inventories are valued at the lower of cost or net realizable value. Costs include materials, labor, external service, and manufacturing overhead and is computed on a first-in-first-out basis. The Company evaluates the carrying value of its inventories taking into consideration such factors as historical and anticipated future sales compared to quantities on hand and the prices the Company expects to obtain for products in its various markets. The Company adjusts excess and obsolete inventories to net realizable value and write-downs of excess and obsolete inventories are recorded as a component of cost of revenues.
Property, Plant and Equipment, net	Property, Plant and Equipment, net Property, plant and equipment are stated at cost, net of accumulated depreciation. Major improvements are capitalized, while repairs and maintenance are expensed as incurred. Depreciation is computed using the straight-line method over the estimated useful lives of the assets or remaining lease term. Land is not subject to depreciation, but land improvements are depreciated over fifteen years. Land leasehold rights and leasehold improvements are depreciated over the lesser of their estimated useful lives or remaining lease terms. Buildings are depreciated up to thirty years. Machinery and equipment are depreciated over a range from three to seven years. Assets subject to lease are depreciated over the lesser of their estimated useful lives or remaining lease terms. Estimated useful lives are periodically reviewed and, when appropriate, changes are made prospectively. When certain events or changes in operating conditions occur, asset lives may be adjusted, and an impairment assessment may be performed on the recoverability of the carrying amounts. When assets are retired or otherwise disposed of, the assets and related accumulated depreciation are removed from the accounts.
Investments	Investments The Company accounts for its equity investments in privately-held companies under the equity method of accounting if the Company has the ability to exercise significant influence in these investments. Distributions received from an equity method investment are classified using the cumulative earnings approach, which means that distributions up to the amount of cumulative equity in earnings recognized will be treated as returns on investment and classified as operating cash flows and those in excess of that amount will be treated as returns of investment and classified as investing cash flows. The Company reviews its equity investments in privately-held companies for impairment whenever events or changes in business circumstances are other than temporary and indicate that the carrying amount of the investments may not be fully recoverable.
Goodwill and Intangible Assets	Goodwill and Intangible Assets Goodwill is recorded when the purchase price of an acquisition exceeds the fair value of the net identified tangible and intangible assets acquired. Purchased intangible assets are carried at cost, net of accumulated amortization, and are included in intangible assets in the Company's consolidated balance sheets. Intangible assets with finite lives are amortized over their estimated useful lives of primarily two to seven years using the straight-line method.
Impairment of Long-lived Assets, Intangible Assets and Goodwill	Impairment of Long-lived Assets, Intangible Assets and Goodwill The Company reviews long-lived assets and identifiable intangible assets with finite lives for impairment whenever events or changes in circumstances indicate that the carrying amount of these assets may not be recoverable. The Company assesses these assets for impairment based on their estimated undiscounted future cash flows. If the carrying value of the assets exceeds the estimated future undiscounted cash flows, the Company recognizes an impairment loss based on the excess of the carrying amount over the fair value of the assets. The Company evaluates goodwill and indefinite lived intangible assets for impairment at least annually at the beginning of the fourth quarter of each fiscal year or whenever an event occurs or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying amount. The evaluation includes consideration of qualitative factors including industry and market considerations, overall financial performance, and other relevant events and factors affecting the reporting unit. If the Company determine that a quantitative analysis is necessary, the Company performs a step one analysis, which consists of a comparison of the fair value of a reporting unit against its carrying amount, including the goodwill allocated to each reporting unit. The Company determines the fair value of its reporting units based on a combination of income and market approaches. The income approach is based on the present value of estimated future cash flows of the reporting units, and the market approach is based on a market multiple calculated for each reporting unit based on market data of other companies engaged in similar business. If the carrying amount of the reporting unit is in excess of its fair value, the difference between the fair value and carrying amount is recorded as an impairment loss. The impairment test for intangible assets with indefinite useful lives, if any, consists of a comparison of fair value to carrying value, with any excess of carrying value over fair value being recorded as an impairment loss. In fiscal years 2021, 2020 and 2019, the Company performed the annual goodwill impairment test for our two reporting units and found no impairment.
Loss Contingencies	Loss Contingencies From time to time, the Company is involved in legal proceedings, claims and government inspections or investigations, customs and duties audits, other contingency matters, both inside and outside the United States, arising in the ordinary course of its business or otherwise. The Company accrues amounts for probable losses, to the extent they can be reasonably estimated, that it believes are adequate to address any liabilities related to legal proceedings and other loss contingencies that the Company believes will result in a probable loss (including, among other things, probable settlement value). A loss or a range of loss is disclosed when it is reasonably possible that a material loss will be incurred and can be estimated or when it is reasonably possible that the amount of a loss, when material, will exceed the recorded provision. When a loss contingency is probable but not reasonably estimable the nature of the contingency and the fact that an estimate cannot be made is disclosed. See Note 13. Commitments and Contingencies, for further information regarding certain of our contractual obligations and contingencies.
Product Warranty	Product Warranty The Company warrants most of its products for a specific period of time, usually 12 to 24 months from delivery or acceptance, against material defects. The Company provides for the estimated future costs of warranty obligations in cost of revenues when the related revenues are recognized. The accrued warranty costs represent the best estimate at the time of sale of the total costs that the Company will incur to repair or replace product parts that fail while still under warranty. The amount of the accrued estimated warranty costs obligation for established products is primarily based on historical experience as to product failures adjusted for current information on repair costs. For new products, estimates include the historical experience of similar products, as well as a reasonable allowance for warranty expenses associated with new products. On a quarterly basis, the Company reviews the accrued warranty costs and updates the historical warranty cost trends, if required.
Leases	Leases The Company determines if an arrangement is or contains a lease at the inception of an arrangement. The Company's operating lease right-of-use ("ROU") assets represent the right to use an underlying asset over the lease term and lease liabilities represent its obligation to make lease payments arising from the lease. ROU assets may also include initial direct costs incurred and prepaid lease payments, less lease incentives. Lease liabilities and their corresponding ROU assets are recognized based on the present value of lease payments over the lease term, discounted using the Company's incremental borrowing rate ("IBR"). The Company recognizes operating leases with lease terms of more than twelve months in operating lease assets, current operating lease liabilities, and operating lease liabilities on its consolidated balance sheets. The Company recognizes finance leases with lease terms of more than twelve months in property, plant, and equipment, net, accrued liabilities and other current liabilities, and other long-term liabilities on its consolidated balance sheets. For purposes of calculating lease liabilities and the corresponding ROU assets, the Company's lease term may include options to extend or terminate the lease when it is reasonably certain that it will exercise that option.
Revenue Recognition	Revenue Recognition Effective September 29, 2018, the Company adopted the requirements of Accounting Standards Update (“ASU”) 2014-09 and related amendments, Revenue from Contracts with Customers (“ASC 606”), which superseded all prior revenue recognition methods and industry-specific guidance. The Company’s revenues are derived primarily from the sale of hardware and services. The Company recognizes its revenues net of any value-added or sales tax and net of sales discounts. The Company sells a high proportion of its X-ray products to a limited number of OEM customers. X-ray tubes, digital detectors and image-processing tools and security and inspection products are generally sold on a stand-alone basis. However, the Company occasionally sells its digital detectors, X-ray tubes and imaging processing tools as a package that is optimized for digital X-ray imaging and sells its Linatron ® X-ray accelerators together with its imaging processing software and image detection products to OEM customers that incorporate them into their inspection systems. Service contracts are often sold with certain security and inspection products and computer-aided detection products. The Company determines revenue recognition through the following steps: •Identification of the contract, or contracts, with a customer •Identification of the performance obligations in the contract •Determination of the transaction price •Allocation of the transaction price to the performance obligations in the contract •Recognition of revenue when, or as, a performance obligation is satisfied Transaction price and allocation to performance obligations Transaction prices of products or services are typically based on contracted rates. To the extent that the transaction price includes variable consideration, the Company estimates the amount of variable consideration that should be included in the transaction price utilizing the expected value method when there is a large number of transactions with similar characteristics or the most likely amount method when there are two possible outcomes, depending on the circumstances of the transaction, to which the Company expects to be entitled. Variable consideration is included in the transaction price if, in the Company’s judgment, it is probable that a significant future reversal of cumulative revenue under the contract will not occur. Estimates of variable consideration and determination of whether to include estimated amounts in the transaction price are based largely on an assessment of the Company’s anticipated performance and all information (historical, current and forecasted) that is reasonably available. The Company allows customers to return specific parts of purchased X-ray tubes for a partial refund credit, which is identified as variable consideration. For sales with a right of return, revenue is reduced for expected returns, a liability is recorded for expected returns, and an asset is recorded for the right to recover products from customers on settling the liability. The Company recognizes a reduction to revenue and cost of sales at the time of sale and a corresponding contract liability and contract asset. The Company records this estimate based on the historical volume of product returns and adjusts the estimate on a quarterly basis based on the current quarter sales and current quarter returns. If a contract contains a single performance obligation, the entire transaction price is allocated to the single performance obligation. Contracts that contain multiple performance obligations require an allocation of the transaction price based on the estimated relative standalone selling prices of the promised products or services underlying each performance obligation. The Company determines standalone selling prices based on the price at which the performance obligation is sold separately. Contracts and performance obligations The Company accounts for a contract with a customer when there is an approval and commitment from both parties, the rights of the parties are identified, payment terms are identified, the contract has commercial substance and collectability of the consideration is probable. The Company's performance obligations consist mainly of transferring control of products and services identified in the contracts or purchase orders. For each contract, the Company considers the obligation to transfer products and services to the customer, which are distinct, to be performance obligations. Recognition of revenue Revenue is recognized when, or as, obligations under the terms of a contract are satisfied, which occurs when control of the promised products or services is transferred to customers. Revenue is measured as the amount of consideration the Company expects to receive in exchange for transferring products or services to a customer. Product revenue is generally recognized when the customer obtains control of the Company’s product, which occurs at a point in time, and may be upon shipment or upon delivery based on the contractual shipping terms of a contract. Service revenue is generally recognized over the term of the service contract. Services are expected to be transferred to the customer throughout the term of the contract and the Company believes recognizing revenue ratably over the term of the contract best depicts the transfer of value to the customer. Disaggregation of Revenue Revenue is disaggregated from contracts between geography and by reportable operating segment, which the Company believes best depicts how the nature, amount, timing, and uncertainty of revenues and cash flows are affected by economic factors. Refer to Note 17. Segment Information, included in this report, for the disaggregation of the Company’s revenue based on reportable operating segments and disaggregated by geographic region. Contract Balances Contract assets are included within the Prepaid expenses and other current assets, and Other assets balances in the consolidated balance sheets. Contract liabilities, which also includes refund obligations, are included within the Accrued liabilities and other current liabilities, Deferred revenues, and Other long-term liabilities balances in the consolidated balance sheets. Costs to Obtain or Fulfill a Customer Contract The Company has certain costs to obtain and fulfill a customer contract, such as commissions and shipping costs. The Company recognizes the incremental costs of obtaining contracts as an expense when incurred if the amortization period of the assets that the Company otherwise would have recognized is one year or less. Incremental costs of obtaining contracts that would be recognized over greater than one year are not material. The Company accounts for shipping and handling activities related to contracts with customers as costs to fulfill the promise to transfer the associated products. These costs are included as a component of cost of revenues. Deferred Revenues Deferred revenue primarily represents (i) the amount received applicable to non-software products for which parts and services under the warranty contracts have not been delivered, and (ii) the amount received for service contracts for which the services have not been rendered.
Allowance for Credit Losses	Allowance for Credit Losses The Company evaluates the creditworthiness of customers prior to authorizing shipment for all major sale transactions. On a quarterly basis, the Company considers historical trends, current information and any reasonable and supportable forecasts to determine if an amount should be included in the allowance for credit losses.
Share-Based Compensation Expense	Share-Based Compensation Expense The Company has an equity-based incentive plan that provides for the grant of nonqualified stock options and restricted stock units to directors, officers and other employees. The Company also permits employees to purchase shares under the Varex employee stock purchase plan. The Company values stock options granted and the option component of the shares of common stock purchased under the equity-based incentive plans and stock purchased under the employee stock purchase plan using the Black-Scholes option-pricing model. Share-based compensation expense for restricted stock units is measured using the fair value of the Company’s stock on the date of grant and is amortized over the award’s respective service period. The Black-Scholes option-pricing model requires the input of certain assumptions, and changes in the assumptions can materially affect the fair value estimates of share-based payment awards. The Company measures and recognizes expense for all share-based payment awards based on their fair values. Share-based compensation expense recognized in the consolidated statements of operations includes compensation expense for the share-based payment awards based on the grant date fair value estimated in accordance with the guidance on share-based compensation. The Company records forfeitures as they occur. The Company attributes the value of share-based compensation to expense using the straight-line method. The Company considers only the direct tax impacts of share-based compensation awards when calculating the amount of tax windfalls or shortfalls.
Software Development Costs	Software Development Costs Costs for the development of new software products and substantial enhancements to existing software products are expensed as incurred until technological feasibility has been established, at which time any additional costs would be capitalized. No costs associated with the development of software have been capitalized, as the Company believes its current software development process is essentially completed concurrent with the establishment of technological feasibility.
Research and Development	Research and Development Research and development costs are expensed as incurred. These costs primarily include employees’ compensation, consulting fees and material costs.
Taxes on Earnings	Taxes on Income Current income tax expense or benefit is the amount of income taxes expected to be payable or receivable for the current year. Deferred income tax liabilities or assets are established for the expected future tax consequences resulting from the differences in financial reporting and tax bases of assets and liabilities. Future changes in tax regulation can have a material impact, including tax rate changes or the realization of deferred tax assets. A valuation allowance is provided if it is more likely than not that some or all of the deferred tax assets will not be realized. U.S. Tax Reform introduced a limitation of business interest deduction under IRC Section 163(j), which may be difficult to utilize without significant taxable income. Also, net operating loss carryforwards in jurisdictions with current losses provide uncertainty for realization. In addition, we provide reserves for uncertain tax positions when such tax positions do not meet the recognition thresholds or measurement standards prescribed by the authoritative guidance for accounting for income taxes. A portion of the U.S. general business tax credits for research outside of the financial statement line for research and development ("R&D") have a small degree of uncertainty. A reasonable reserve is maintained on the uncertain portion until either the Internal Revenue Service chooses to audit, or the statute of limitation expires. A reserve for R&D is typical for companies who calculate and utilize this general business credit. Amounts for uncertain tax positions are adjusted in periods when new information becomes available or when positions are effectively settled. Interest and penalties related to uncertain tax positions are recognized as a component of income tax expense.
Foreign Currency Translation	Foreign Currency Translation The Company uses the U.S. Dollar predominately as the functional currency of its foreign operations. Gains and losses from remeasurement of foreign currency balances into U.S. Dollars are included in the consolidated statements of operations. For the foreign subsidiaries where the local currency is the functional currency, translation adjustments of foreign currency financial statements into U.S. dollars are recorded to a separate component of accumulated other comprehensive income.
Recently Adopted Accounting Pronouncements and Recent Accounting Standards Updates Not Yet Effective	Recently Adopted Accounting Pronouncements In June 2016, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2016-13, Measurement of Credit Losses on Financial Instruments. This pronouncement changes the impairment model for most financial assets and certain other instruments, including trade and other receivables, held-to-maturity debt securities and loans and replaces the incurred loss methodology with a new, forward-looking “expected loss” model that considers the risk of loss over the asset’s contractual life, even if remote, historical experience, current conditions, and reasonable and supportable forecasts of future relevant events. The Company adopted this ASU on October 3, 2020, using a modified retrospective approach. The adoption of ASU 2016-13 did not have a material impact on the Company's consolidated financial statements and related disclosures. Recent Accounting Standards Updates Not Yet Effective In August 2020, the FASB issued ASU 2020-06, Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity. The standard removes certain separation models in ASC 470-20 for convertible instruments, and, as a result, embedded conversion features are no longer separated from the host contract for convertible instruments with conversion features that are not required to be accounted for as derivatives under ASC 815. The convertible debt instruments will be accounted for as a single liability measured at amortized cost. This will also result in the interest expense recognized for convertible debt instruments to be typically closer to the coupon interest rate. Further, the ASU made amendments to the earnings per share (“EPS”) guidance in Topic 260 for convertible instruments, the most significant impact of which is requiring the use of the if-converted method for diluted EPS calculation, and no longer allowing the net share settlement method. The ASU is effective for interim and annual periods beginning after December 15, 2021, with early adoption permitted for fiscal years beginning after December 15, 2020. Adoption of the ASU can either be on a modified retrospective or full retrospective basis. We are currently evaluating the impacts of this ASU on our consolidated financial statements. In March 2020, the FASB issued ASU 2020-04, Facilitation of the Effects of Reference Rate Reform on Financial Reporting, to provide optional guidance for a limited period of time to ease the potential burden in accounting for (or recognizing the effects of) reference rate (e.g., LIBOR) reform on financial reporting. Adoption of the guidance is elective and is permitted from March 12, 2020 through December 31, 2022. The Company will evaluate transactions or contract modifications occurring as a result of reference rate reform and determine whether to apply the optional guidance on an ongoing basis. The Company does not expect that the new guidance will have a material impact on its financial position, results of operations or cash flows. In December 2019, the FASB issued ASU 2019-12, Simplifying the Accounting for Income Taxes, which simplifies the accounting for income taxes by removing certain exceptions to the current guidance, and improving the consistent application of and simplification of other areas of the guidance. The standard is effective for the Company beginning in the first quarter of fiscal year 2022. The Company does not expect that the new guidance will have a material impact on its financial position, results of operations, or cash flows.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)

12 Months Ended

Oct. 01, 2021

The accompanying consolidated financial statements have been prepared by the Company pursuant to the rules and regulations of the SEC and prepared in accordance with accounting principles generally accepted in the United States ("GAAP"). The Company has consolidated all the majority owned subsidiaries and entities over which we have control. All intercompany balances and transactions have been eliminated in consolidation.

Segment Reporting

Segment Reporting The Company has two reportable operating segments; (i) Medical and (ii) Industrial.

Fiscal Year

The fiscal years of the Company as reported are the 52 or 53-week period ending on the Friday nearest September 30. Fiscal year 2021 was the 52-week period that ended October 1, 2021, fiscal year 2020 was the 53-week period that ended October 2, 2020, and fiscal year 2019 was the 52-week period that ended September 27, 2019.

Variable Interest Entities

Variable Interest Entities For entities in which the Company has variable interests, the Company focuses on identifying which entity has the power to direct the activities that most significantly impact the variable interest entity’s economic performance and which entity has the obligation to absorb losses or the right to receive residual returns from the variable interest entity. If the Company is the primary beneficiary of a variable interest entity, the assets, liabilities and results of operations of the variable interest entity will be included in the Company’s consolidated financial statements. As of October 1, 2021, the Company had variable interests in two entities, neither of which were consolidated by the Company.

Use of Estimates

Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting periods. Such estimates include the valuation of inventories, valuation of goodwill and intangible assets, warranties, contract liabilities, long-lived asset valuations, impairment on investments, valuation of financial instruments, and taxes on income. Actual results could differ from these estimates.

Cash and Cash Equivalents and Restricted Cash

Cash and Cash Equivalents

The Company considers currency on hand, demand deposits, time deposits and all highly-liquid investments with an original maturity of three months or less at the date of purchase to be cash and cash equivalents.

Restricted Cash

Restricted cash primarily consists of cash collateral related to certain leases and inventory arrangements. Restricted cash is

included in other assets on the consolidated balance sheets.

Fair Value

Fair value is defined 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 at the measurement date. There is a three-level fair value hierarchy that prioritizes the inputs used to measure fair value. This hierarchy requires entities to maximize the use of observable inputs and minimize the use of unobservable inputs. The three levels of inputs used to measure fair value are as follows:

Level 1—Quoted prices in active markets for identical assets or liabilities.

Level 2—Observable inputs other than quoted prices included in Level 1, such as quoted prices for similar assets and liabilities in active markets; quoted prices for identical or similar assets and liabilities in markets that are not active; or, other inputs that are observable or can be corroborated by observable market data.

Level 3—Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.

Derivative instruments and hedging activities

The Company records all derivatives on the consolidated balance sheets at fair value as of the reporting date. For derivative instruments that are designated and qualify as cash flow hedges, the gain or loss on the derivative is reported as a component of other comprehensive income or loss and reclassified from accumulated other comprehensive income into earnings when the hedged transaction affects earnings. For derivatives that are designated and qualify as net investment hedges, the gain or loss on the derivative is reported as a component of other comprehensive income or loss until the hedged item is sold. The portion of the change in fair value

of the Company's net investment hedges (or cross currency swaps) related to the cross-currency basis spread is an excluded component in the assessment of the effectiveness of these net investment hedges (or cross currency swaps). A qualitative assessment of hedge effectiveness is performed on a quarterly basis, unless facts and circumstances indicate the hedge may no longer be highly effective, in which case, a quantitative assessment of hedge effectiveness is performed.

Concentration of Risk

Financial instruments that potentially expose the Company to concentrations of credit risk consist principally of cash, cash equivalents and trade accounts receivable. Cash held with financial institutions may exceed the Federal Deposit Insurance Corporation insurance limits or similar limits in foreign jurisdictions. The Company has not experienced any losses on its deposits of cash and cash equivalents. The Company performs ongoing credit evaluations of its customers and, except for government tenders, group purchases and orders with a letter of credit, its industrial customers often provide a down payment. The Company maintains an allowance for doubtful accounts based upon the expected collectability of all accounts receivable. The Company obtains some of the components in its products from a limited group of suppliers or from a single-source supplier.

Inventories

Inventories are valued at the lower of cost or net realizable value. Costs include materials, labor, external service, and manufacturing overhead and is computed on a first-in-first-out basis. The Company evaluates the carrying value of its inventories taking into consideration such factors as historical and anticipated future sales compared to quantities on hand and the prices the Company expects to obtain for products in its various markets. The Company adjusts excess and obsolete inventories to net realizable value and write-downs of excess and obsolete inventories are recorded as a component of cost of revenues.

Property, Plant and Equipment, net

Property, plant and equipment are stated at cost, net of accumulated depreciation. Major improvements are capitalized, while repairs and maintenance are expensed as incurred. Depreciation is computed using the straight-line method over the estimated useful lives of the assets or remaining lease term. Land is not subject to depreciation, but land improvements are depreciated over fifteen years. Land leasehold rights and leasehold improvements are depreciated over the lesser of their estimated useful lives or remaining lease terms. Buildings are depreciated up to thirty years. Machinery and equipment are depreciated over a range from three to seven years. Assets subject to lease are depreciated over the lesser of their estimated useful lives or remaining lease terms. Estimated useful lives are periodically reviewed and, when appropriate, changes are made prospectively. When certain events or changes in operating conditions occur, asset lives may be adjusted, and an impairment assessment may be performed on the recoverability of the carrying

amounts. When assets are retired or otherwise disposed of, the assets and related accumulated depreciation are removed from the accounts.

Investments

Investments The Company accounts for its equity investments in privately-held companies under the equity method of accounting if the Company has the ability to exercise significant influence in these investments. Distributions received from an equity method investment are classified using the cumulative earnings approach, which means that distributions up to the amount of cumulative equity in earnings recognized will be treated as returns on investment and classified as operating cash flows and those in excess of that amount will be treated as returns of investment and classified as investing cash flows. The Company reviews its equity investments in privately-held companies for impairment whenever events or changes in business circumstances are other than temporary and indicate that the carrying amount of the investments may not be fully recoverable.

Goodwill and Intangible Assets

Goodwill is recorded when the purchase price of an acquisition exceeds the fair value of the net identified tangible and intangible assets acquired. Purchased intangible assets are carried at cost, net of accumulated amortization, and are included in intangible assets in the Company's consolidated balance sheets. Intangible assets with finite lives are amortized over their estimated useful lives of primarily two to seven years using the straight-line method.

Impairment of Long-lived Assets, Intangible Assets and Goodwill

The Company reviews long-lived assets and identifiable intangible assets with finite lives for impairment whenever events or changes in circumstances indicate that the carrying amount of these assets may not be recoverable. The Company assesses these assets for impairment based on their estimated undiscounted future cash flows. If the carrying value of the assets exceeds the estimated future undiscounted cash flows, the Company recognizes an impairment loss based on the excess of the carrying amount over the fair value of the assets.

The Company evaluates goodwill and indefinite lived intangible assets for impairment at least annually at the beginning of the fourth quarter of each fiscal year or whenever an event occurs or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying amount. The evaluation includes consideration of qualitative factors including industry and market considerations, overall financial performance, and other relevant events and factors affecting the reporting unit. If the Company determine that a quantitative analysis is necessary, the Company performs a step one analysis, which consists of a comparison of the fair value of a reporting unit against its carrying amount, including the goodwill allocated to each reporting unit. The Company determines the fair value of its reporting units based on a combination of income and market approaches. The income approach is based on the present value of estimated future cash flows of the reporting units, and the market approach is based on a market multiple calculated for each reporting unit based on market data of other companies engaged in similar business. If the carrying amount of the reporting unit is in excess of its fair value, the difference between the fair value and carrying amount is recorded as an

impairment loss. The impairment test for intangible assets with indefinite useful lives, if any, consists of a comparison of fair value to carrying value, with any excess of carrying value over fair value being recorded as an impairment loss. In fiscal years 2021, 2020 and 2019, the Company performed the annual goodwill impairment test for our two reporting units and found no impairment.

Loss Contingencies

From time to time, the Company is involved in legal proceedings, claims and government inspections or investigations, customs and duties audits, other contingency matters, both inside and outside the United States, arising in the ordinary course of its business or otherwise. The Company accrues amounts for probable losses, to the extent they can be reasonably estimated, that it believes are adequate to address any liabilities related to legal proceedings and other loss contingencies that the Company believes will result in a probable loss (including, among other things, probable settlement value). A loss or a range of loss is disclosed when it is reasonably possible that a material loss will be incurred and can be estimated or when it is reasonably possible that the amount of a loss, when material, will exceed the recorded provision. When a loss contingency is probable but not reasonably estimable the nature of the contingency and the fact that an estimate cannot be made is disclosed. See Note 13. Commitments and Contingencies, for further information regarding certain of our contractual obligations and contingencies.

Product Warranty

The Company warrants most of its products for a specific period of time, usually 12 to 24 months from delivery or acceptance, against material defects. The Company provides for the estimated future costs of warranty obligations in cost of revenues when the related revenues are recognized. The accrued warranty costs represent the best estimate at the time of sale of the total costs that the Company will incur to repair or replace product parts that fail while still under warranty.

The amount of the accrued estimated warranty costs obligation for established products is primarily based on historical experience as to product failures adjusted for current information on repair costs. For new products, estimates include the historical experience of similar products, as well as a reasonable allowance for warranty expenses associated with new products. On a quarterly basis, the Company reviews the accrued warranty costs and updates the historical warranty cost trends, if required.

Leases

The Company determines if an arrangement is or contains a lease at the inception of an arrangement. The Company's operating lease right-of-use ("ROU") assets represent the right to use an underlying asset over the lease term and lease liabilities represent its obligation to make lease payments arising from the lease. ROU assets may also include initial direct costs incurred and prepaid lease payments, less lease incentives. Lease liabilities and their corresponding ROU assets are recognized based on the present value of lease payments over the lease term, discounted using the Company's incremental borrowing rate ("IBR"). The Company recognizes operating leases with lease terms of more than twelve months in operating lease assets, current operating lease liabilities, and operating lease liabilities on its consolidated balance sheets. The Company recognizes finance leases with lease terms of more than twelve months in property, plant, and equipment, net, accrued liabilities and other current liabilities, and other long-term liabilities on its consolidated balance sheets. For purposes of calculating lease liabilities and the corresponding ROU assets, the Company's lease term may include options to extend or terminate the lease when it is reasonably certain that it will exercise that option.

Revenue Recognition

Effective September 29, 2018, the Company adopted the requirements of Accounting Standards Update (“ASU”) 2014-09 and related amendments, Revenue from Contracts with Customers (“ASC 606”), which superseded all prior revenue recognition methods and industry-specific guidance. The Company’s revenues are derived primarily from the sale of hardware and services. The Company recognizes its revenues net of any value-added or sales tax and net of sales discounts.

The Company sells a high proportion of its X-ray products to a limited number of OEM customers. X-ray tubes, digital detectors and image-processing tools and security and inspection products are generally sold on a stand-alone basis. However, the Company occasionally sells its digital detectors, X-ray tubes and imaging processing tools as a package that is optimized for digital X-ray imaging and sells its Linatron ® X-ray accelerators together with its imaging processing software and image detection products to OEM customers that incorporate them into their inspection systems. Service contracts are often sold with certain security and inspection products and computer-aided detection products.

The Company determines revenue recognition through the following steps:

•Identification of the contract, or contracts, with a customer

•Identification of the performance obligations in the contract

•Determination of the transaction price

•Allocation of the transaction price to the performance obligations in the contract

•Recognition of revenue when, or as, a performance obligation is satisfied

Transaction price and allocation to performance obligations

Transaction prices of products or services are typically based on contracted rates. To the extent that the transaction price includes variable consideration, the Company estimates the amount of variable consideration that should be included in the transaction price utilizing the expected value method when there is a large number of transactions with similar characteristics or the most likely amount method when there are two possible outcomes, depending on the circumstances of the transaction, to which the Company expects to be entitled. Variable consideration is included in the transaction price if, in the Company’s judgment, it is probable that a significant future reversal of cumulative revenue under the contract will not occur. Estimates of variable consideration and determination of whether to include estimated amounts in the transaction price are based largely on an assessment of the Company’s anticipated performance and all information (historical, current and forecasted) that is reasonably available.

The Company allows customers to return specific parts of purchased X-ray tubes for a partial refund credit, which is identified as variable consideration. For sales with a right of return, revenue is reduced for expected returns, a liability is recorded for expected returns, and an asset is recorded for the right to recover products from customers on settling the liability. The Company recognizes a reduction to revenue and cost of sales at the time of sale and a corresponding contract liability and contract asset. The Company records this estimate based on the historical volume of product returns and adjusts the estimate on a quarterly basis based on the current quarter sales and current quarter returns.

If a contract contains a single performance obligation, the entire transaction price is allocated to the single performance obligation. Contracts that contain multiple performance obligations require an allocation of the transaction price based on the estimated relative standalone selling prices of the promised products or services underlying each performance obligation. The Company determines standalone selling prices based on the price at which the performance obligation is sold separately.

Contracts and performance obligations

The Company accounts for a contract with a customer when there is an approval and commitment from both parties, the rights of the parties are identified, payment terms are identified, the contract has commercial substance and collectability of the consideration is probable. The Company's performance obligations consist mainly of transferring control of products and services identified in the contracts or purchase orders. For each contract, the Company considers the obligation to transfer products and services to the customer, which are distinct, to be performance obligations.

Recognition of revenue

Revenue is recognized when, or as, obligations under the terms of a contract are satisfied, which occurs when control of the promised products or services is transferred to customers. Revenue is measured as the amount of consideration the Company expects to receive in exchange for transferring products or services to a customer.

Product revenue is generally recognized when the customer obtains control of the Company’s product, which occurs at a point in time, and may be upon shipment or upon delivery based on the contractual shipping terms of a contract.

Service revenue is generally recognized over the term of the service contract. Services are expected to be transferred to the customer throughout the term of the contract and the Company believes recognizing revenue ratably over the term of the contract best depicts the transfer of value to the customer.

Disaggregation of Revenue

Revenue is disaggregated from contracts between geography and by reportable operating segment, which the Company believes best depicts how the nature, amount, timing, and uncertainty of revenues and cash flows are affected by economic factors. Refer to Note 17. Segment Information, included in this report, for the disaggregation of the Company’s revenue based on reportable operating segments and disaggregated by geographic region.

Contract Balances

Contract assets are included within the Prepaid expenses and other current assets, and Other assets balances in the consolidated balance sheets. Contract liabilities, which also includes refund obligations, are included within the Accrued liabilities and other current liabilities, Deferred revenues, and Other long-term liabilities balances in the consolidated balance sheets.

Costs to Obtain or Fulfill a Customer Contract

The Company has certain costs to obtain and fulfill a customer contract, such as commissions and shipping costs. The Company recognizes the incremental costs of obtaining contracts as an expense when incurred if the amortization period of the assets that the Company otherwise would have recognized is one year or less. Incremental costs of obtaining contracts that would be recognized over greater than one year are not material. The Company accounts for shipping and handling activities related to contracts with customers as costs to fulfill the promise to transfer the associated products. These costs are included as a component of cost of revenues.

Deferred Revenues

Deferred revenue primarily represents (i) the amount received applicable to non-software products for which parts

and services under the warranty contracts have not been delivered, and (ii) the amount received for service contracts for

which the services have not been rendered.

Allowance for Credit Losses

Allowance for Credit Losses The Company evaluates the creditworthiness of customers prior to authorizing shipment for all major sale transactions. On a quarterly basis, the Company considers historical trends, current information and any reasonable and supportable forecasts to determine if an amount should be included in the allowance for credit losses.

Share-Based Compensation Expense

The Company has an equity-based incentive plan that provides for the grant of nonqualified stock options and restricted stock units to directors, officers and other employees. The Company also permits employees to purchase shares under the Varex employee stock purchase plan.

The Company values stock options granted and the option component of the shares of common stock purchased under the equity-based incentive plans and stock purchased under the employee stock purchase plan using the Black-Scholes option-pricing model. Share-based compensation expense for restricted stock units is measured using the fair value of the Company’s stock on the date of grant and is amortized over the award’s respective service period. The Black-Scholes option-pricing model requires the input of certain assumptions, and changes in the assumptions can materially affect the fair value estimates of share-based payment awards.

The Company measures and recognizes expense for all share-based payment awards based on their fair values. Share-based compensation expense recognized in the consolidated statements of operations includes compensation expense for the share-based payment awards based on the grant date fair value estimated in accordance with the guidance on share-based compensation. The Company records forfeitures as they occur. The Company attributes the value of share-based compensation to expense using the straight-line method. The Company considers only the direct tax impacts of share-based compensation awards when calculating the amount of tax windfalls or shortfalls.

Software Development Costs

Costs for the development of new software products and substantial enhancements to existing software products are expensed as incurred until technological feasibility has been established, at which time any additional costs would be capitalized. No costs associated with the development of software have been capitalized, as the Company believes its current software development process is essentially completed concurrent with the establishment of technological feasibility.

Research and Development

Research and Development Research and development costs are expensed as incurred. These costs primarily include employees’ compensation, consulting fees and material costs.

Taxes on Earnings

Taxes on Income Current income tax expense or benefit is the amount of income taxes expected to be payable or receivable for the current year. Deferred income tax liabilities or assets are established for the expected future tax consequences resulting from the differences in financial reporting and tax bases of assets and liabilities. Future changes in tax regulation can have a material impact, including tax rate changes or the realization of deferred tax assets. A valuation allowance is provided if it is more likely than not that some or all of the deferred tax assets will not be realized. U.S. Tax Reform introduced a limitation of business interest deduction under IRC Section 163(j), which may be difficult to utilize without significant taxable income. Also, net operating loss carryforwards in jurisdictions with current losses provide uncertainty for realization. In addition, we provide reserves for uncertain tax positions when such tax positions do not meet the recognition thresholds or measurement standards prescribed by the authoritative guidance for accounting for income taxes. A portion of the U.S. general business tax credits for research outside of the financial statement line for research and development ("R&D") have a small degree of uncertainty. A reasonable reserve is maintained on the uncertain portion until either the Internal Revenue Service chooses to audit, or the statute of limitation expires. A reserve for R&D is typical for companies who calculate and utilize this general business credit. Amounts for uncertain tax positions are adjusted in periods when new information becomes available or when positions are effectively settled. Interest and penalties related to uncertain tax positions are recognized as a component of income tax expense.

Foreign Currency Translation

Foreign Currency Translation The Company uses the U.S. Dollar predominately as the functional currency of its foreign operations. Gains and losses from remeasurement of foreign currency balances into U.S. Dollars are included in the consolidated statements of operations. For the foreign subsidiaries where the local currency is the functional currency, translation adjustments of foreign currency financial statements into U.S. dollars are recorded to a separate component of accumulated other comprehensive income.

Recently Adopted Accounting Pronouncements and Recent Accounting Standards Updates Not Yet Effective

Recently Adopted Accounting Pronouncements

In June 2016, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2016-13, Measurement of Credit Losses on Financial Instruments. This pronouncement changes the impairment model for most financial assets and certain other instruments, including trade and other receivables, held-to-maturity debt securities and loans and replaces the incurred loss methodology with a new, forward-looking “expected loss” model that considers the risk of loss over the asset’s contractual life, even if remote, historical experience, current conditions, and reasonable and supportable forecasts of future relevant events. The Company adopted this ASU on October 3, 2020, using a modified retrospective approach. The adoption of ASU 2016-13 did not have a material impact on the Company's consolidated financial statements and related disclosures.

Recent Accounting Standards Updates Not Yet Effective

In August 2020, the FASB issued ASU 2020-06, Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity. The standard removes certain separation models in ASC 470-20 for convertible instruments, and, as a result, embedded conversion features are no longer separated from the host contract for convertible instruments with conversion features that are not required to be accounted for as derivatives under ASC 815. The convertible debt instruments will be accounted for as a single liability measured at amortized cost. This will also result in the interest expense recognized for convertible debt instruments to be typically closer to the coupon interest rate. Further, the ASU made amendments to the earnings per share (“EPS”) guidance in Topic 260 for convertible instruments, the most significant impact of which is requiring the use of the if-converted method for diluted EPS calculation, and no longer allowing the net share settlement method. The ASU is effective for interim and annual periods beginning after December 15, 2021, with early adoption permitted for fiscal years beginning after December 15, 2020. Adoption of the ASU can either be on a modified retrospective or full retrospective basis. We are currently evaluating the impacts of this ASU on our consolidated financial statements.

In March 2020, the FASB issued ASU 2020-04, Facilitation of the Effects of Reference Rate Reform on Financial Reporting, to provide optional guidance for a limited period of time to ease the potential burden in accounting for (or recognizing the effects of) reference rate (e.g., LIBOR) reform on financial reporting. Adoption of the guidance is elective and is permitted from March 12, 2020 through December 31, 2022. The Company will evaluate transactions or contract modifications occurring as a result of reference rate reform and determine whether to apply the optional guidance on an ongoing basis. The Company does not expect that the new guidance will have a material impact on its financial position, results of operations or cash flows.

In December 2019, the FASB issued ASU 2019-12, Simplifying the Accounting for Income Taxes, which simplifies the accounting for income taxes by removing certain exceptions to the current guidance, and improving the consistent application of and simplification of other areas of the guidance. The standard is effective for the Company beginning in the first quarter of fiscal year 2022. The Company does not expect that the new guidance will have a material impact on its financial position, results of operations, or cash flows.
