Organization, Consolidation and Presentation of Financial Statements [Abstract]
The Company and its Significant Accounting Policies	Note 1. The Company and its Significant Accounting Policies The Company Accuray Incorporated (together with its subsidiaries, the “Company” or “Accuray”) designs, develops and sells advanced radiosurgery and radiation therapy systems for the treatment of tumors throughout the body. The Company is incorporated in Delaware and on July 31, 2023, it moved its principal place of business from Sunnyvale, California to Madison, Wisconsin. The Company has primary offices in the United States, Switzerland, China, Hong Kong, and Japan, and conducts its business worldwide. Basis of Presentation and Principles of Consolidation The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All significant intercompany transactions and balances have been eliminated in consolidation. The accompanying consolidated financial statements have been prepared in accordance with United States generally accepted accounting principles (“U.S. GAAP”), pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”). Reclassifications Certain amounts on the consolidated statements of cash flows and consolidated statements of stockholders equity in prior periods have been reclassified to conform to current year presentation. Risks and Uncertainties The Company is subject to risks and uncertainties caused by events with significant geopolitical and macroeconomic impacts, including, but not limited to, the COVID-19 pandemic, the Russian invasion of Ukraine, inflation, actions taken to counter inflation, foreign currency exchange rate fluctuations and instability in the banking sector. The Company is also continuing to navigate supply chain and inflation challenges and foreign exchange continues to be a significant headwind that affects the Company’s results of operations. These ongoing supply chain challenges and heightened logistics costs have adversely affected the Company's gross margins and net income or loss, and the Company’s current expectations are that gross margins and net income or loss will continue to be adversely affected by increased material costs and freight and logistic expenses through at least fiscal year 2024, if not longer. Furthermore, certain parts required for the manufacturing and servicing of the Company's products, such as electronic components, are scarce and becoming increasingly difficult to source, even at increased prices. If such parts become unavailable to the Company, it would not be able to manufacture or service our products, which would adversely impact revenue, gross margins, and net income or (loss). The Company expects that the business of its customers and its own business will continue to be adversely impacted, directly or indirectly, by macroeconomic and geopolitical issues, including supply chain issues, inflation, labor, foreign currency exchange rate fluctuations, uncertainty and volatility in the banking and financial services sector, tightening credit markets, the effects of the COVID-19 related restrictions, and other factors that may emerge. The extent of the ongoing impact of these macroeconomic events on our business, our markets and on global economic activity however, is uncertain and the related financial impact cannot be reasonably estimated with any certainty at this time. The Company continues to critically review its liquidity and anticipated capital requirements in light of the significant uncertainty created by geopolitical and macroeconomic conditions. Based on the Company’s cash and cash equivalents balance, available debt facilities, current business plan and revenue prospects, the Company believes that it will have sufficient cash resources and anticipated cash flows to fund its operations for at least the next 12 months. The Company however, is unable to predict with certainty the impact of geopolitical and macroeconomic conditions, including its effect on global supply chain and logistics, will have on its ability to maintain compliance with the debt covenants contained in the credit agreement related to its Credit Facilities (as such terms are defined in Note 9 below), including financial covenants regarding the consolidated fixed charge coverage ratio and consolidated senior net leverage ratio. The Company was in compliance with such covenants at June 30, 2023. Following June 30, 2023, our financial maintenance covenants under the Existing Credit Agreement will become more stringent and, as a result could be more difficult to comply with. These restrictions could adversely affect the Company’s ability to finance its future operations or capital needs, withstand a future downturn in its business or the economy in general, engage in business activities, including future opportunities that may be in its interest, and plan for or react to market conditions or otherwise execute its business strategies. The Company’s ability to comply with the covenants and other terms governing the Credit Facilities will depend in part on its future operating performance. In addition, because substantially all of the Company’s assets are pledged as a security under the Credit Facilities, if the Company is not able to cure any default or repay outstanding borrowings, such assets are subject to the risk of foreclosure by the Company’s lenders. Failure to meet the covenant requirements in the future could cause the Company to be in default and the maturity of the related debt could be accelerated and become immediately payable. This may require the Company to obtain waivers or amendments to the credit agreement in order to maintain compliance and there can be no certainty that any such waiver or amendment will be available, or what the cost of such waiver or amendment, if obtained, would be. If the Company is unable to obtain necessary waivers or amendment and the debt under such credit facility is accelerated, the Company would be required to obtain replacement financing at prevailing market rates, which may not be favorable to the Company. There is no guarantee that the Company would be able to satisfy its obligations if any of its indebtedness is accelerated . Use of Estimates The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues, expenses, and related disclosures at the date of the financial statements. The Company assessed certain accounting matters that generally require consideration of forecasted financial information in context with the information reasonably available to the Company. A ctual results could differ materially from those estimates. Foreign Currency The Company’s international subsidiaries use their local currencies as their functional currencies. For those subsidiaries, assets and liabilities are translated at exchange rates in effect at the balance sheet date and income and expense accounts at the average exchange rate. Resulting translation adjustments are excluded from the determination of net income or loss and are recorded in accumulated other comprehensive income (loss) as a separate component of stockholders’ equity. Net foreign currency exchange transaction gains or losses are included as a component of other expense, net, in the Company’s consolidated statements of operations and comprehensive income (loss). Cash, Cash Equivalents and Restricted Cash 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. Cash and cash equivalents are held in various financial institutions in the United States and internationally. Restricted cash primarily consists of cash that is temporarily held in bank accounts which are under the control of the lender to the Credit Facilities, ce rtificates of deposit held as guarantees in connection with customer contracts and corporate leases as well as funds held as guarantees for Value‑Added Tax (“VAT”) obligations in a foreign jurisdiction. Fair Value Measurements The carrying values of the Company’s financial instruments including cash equivalents, restricted cash, accounts receivable, accounts payable, and the Credit Facilities, are approximately equal to their respective fair values due to the relatively short‑term nature of these instruments. See Note 7, Fair Value Measurements, of the consolidated financial statements for further information. Concentration of Credit Risk and Other Risks and Uncertainties The Company’s cash and cash equivalents are primarily deposited with several major financial institutions. At times, deposits in these institutions exceed the amount of insurance provided on such deposits. The Company has not experienced any losses in such accounts and believes that it is not exposed to any significant risk on these balances. The Company performs ongoing credit evaluations of its customers and maintains reserves for potential credit losses. Accounts receivable are deemed past due in accordance with the contractual terms of the agreement. The Company maintains an allowance for doubtful accounts based upon the expected collectability of all accounts receivable. Historically, such losses have been within management’s expectations. The Company h ad one customer that represented 10 % or more of total net revenue for the years ended June 30, 2023, 2022, and 2021 , respectively. The Company had one customer a s of June 30, 2023 and two customers as of June 30, 2022 , respectively, that each accounted for more than 10 % of accounts receivable, net. Single‑source suppliers presently provide the Company with several components. In most cases, if a supplier was unable to deliver these components, the Company believes that it would be able to find other sources for these components subject to any regulatory qualifications, if required. Inventories Inventories are stated at the lower of cost (on a first‑in, first‑out basis) or net realizable value. Excess and obsolete inventories are written down based on historical sales and forecasted demand, as judged by management. Revenue Recognition The Company’s revenue consists of product revenue resulting from the sale of systems, system upgrades and service revenue. The Company accounts for a contract with a customer when there is a legally enforceable contract between the Company and its customer, the rights of the parties are identified, the contract has commercial substance, and collectability of the contract consideration is probable. The Company’s revenues are measured based on the consideration specified in the contract with each customer, net of any discounts and taxes collected from customers that are remitted to government authorities. The Company’s revenue is primarily derived from sales of CyberKnife and TomoTherapy platforms and services, which include post-contract customer support (“PCS”), installation services, training and other professional services. The majority of the Company's revenue arrangements consist of multiple performance obligations, which can include system, upgrades, installation, training, services, construction, and consumables. For bundled arrangements, the Company accounts for individual products and services separately if a product or service is separately identifiable from other items in the bundled package and if a customer can benefit from it on its own or with other resources that are readily available to the customer. The Company’s products are generally sold without a right of return, and the Company’s contracts generally provide a fixed transaction price. The Company may offer incentives in the form of discounts, including volume system discounts, which are included in the contract and used to calculate the final fixed price of the arrangement. These discounts may pertain to all performance obligations in a specific contract or may be allocated to a specific performance obligation. The Company reviews payment terms extending beyond one year. If it is determined that a material financing component exists, we recognize this as interest income over time. The Company applies the practical expedient to not adjust for a material financing component if the gap between payment and delivery was expected, at the contract inception, to be less than one year. The Company offers customers the opportunity to trade in their older systems for a discount off the purchase of a new system. The Company generally does not provide specific trade-in prices or upgrade rights at the time of purchase of the original system. Trade-in or upgrade transactions are based on the then fair value of the system and are separately negotiated, taking into consideration circumstances existing at the time of the trade-in or upgrade. Accordingly, implied trade-ins and upgrades discounts are not considered separate performance obligations in system sales agreements. During fiscal years 2023, 2022 and 2021, no fair value has been assigned to any of the systems that were traded-in. The SSP of performance obligations is determined based on observable prices at which the Company separately sells the products and services. If the SSP is not directly observable, then the Company estimates the SSP considering market conditions, entity-specific factors, and information about the customer or class of customer that is reasonably available. The contract consideration allocation is based on the SSP at contract inception. The consideration (net of any discounts) is allocated among separate products and services in a bundle based on their relative SSPs. Contract modifications typically add additional goods or services or change pricing. For such modifications, the most recent SSP is used for reallocation to the remaining performance obligations. The Company recognizes revenue for certain performance obligations at the point in time when control is transferred, such as the delivery of products and upgrades. Service revenue is recognized over the term of the service period as the customer benefits from the services throughout the service period. Revenue related to services that are not part of a service contract and performed on a time-and-materials basis are recognized when performed. Service contracts comprise a single stand-ready performance obligation satisfied over time as our customers simultaneously receive and consume benefits from the Company's performance. This performance obligation constitutes a series of services that are substantially the same and provided over time using the same measure of progress. Revenues derived from these arrangements are recognized over time using an output method based upon the passage of time as this provides a faithful depiction of the pattern of transfer of control. The Company recognizes an asset for the incremental costs of obtaining a contract with a customer when the Company expects to generate future economic benefits from the related revenue-generating contracts. The Company capitalizes incremental contract acquisition costs, and amortizes such costs over a five year period, the period which the Company expects to benefit, based on historical service renewal rates, and expectations of future customer renewals. Most of the Company’s contract costs are associated with its internal sales force compensation program and a portion of its employee bonus program. The Company capitalizes and amortizes the incremental costs of obtaining a contract, primarily related to certain bonuses and sales commissions. The capitalized bonuses and sales commissions are amortized over a period of five years commencing upon the initial transfer of control of the system to the customer. The pattern of amortization is commensurate with the pattern of transfer of control of the performance obligations to the customer. The amortization of these contract assets is included in cost of sales, research and development, sales and marketing, and general and administrative expenses based on department headcount allocations in the consolidated statements of operations. The Company elected to use the practical expedient and expense as incurred commissions related to service renewals and upgrades because the amortization period is one year or less. The Company invoices its customers based on the billing schedules in its sales arrangements. Payment terms vary from 30 to 90 days, or longer, from the date of invoice. Contract assets for the periods presented primarily represent the difference between the revenue that was recognized based on the relative standalone selling price of the related performance obligations satisfied, and the contractual billing terms. Deferred revenue for periods presented primarily relates to service contracts where the service fees are billed up-front, generally quarterly or annually, prior to services being performed. The associated deferred revenue is generally recognized over the term of the service period. The Company did not have any significant impairment losses on its contract assets for any period presented. Deferred Revenue and Customer Advances Deferred revenue primarily consists of unfulfilled obligations from open contracts for which performance has already started including short-shipped items, deferred warranty, training, maintenance services and other unperformed or incomplete performance obligations. Service contracts outside of the warranty period, for maintenance services, in general, are considered month-to-month contracts. Deferred revenue includes deferred warranty expected to be recognized over the remaining warranty period for systems already installed. Customer advances represent payments made by customers in advance of product shipment. Property and Equipment Property and equipment are stated at cost and are depreciated using the straight‑line method over the estimated useful lives of the related assets. Leasehold improvements are depreciated on a straight‑line basis over the remaining term of the lease or the estimated useful life of the asset, whichever is shorter. Machinery and equipment are depreciated over five years . Furniture and fixtures are depreciated over four years . Computer and office equipment and computer software are depreciated over three years . Repairs and maintenance costs, which are not considered improvements and do not extend the useful life of the property and equipment, are expensed as incurred. Software Capitalization Costs Costs for the development of new software products and the substantial enhancements to existing software products for internal use are capitalized when it is considered probable that the software will be fully developed and used to perform its intended function. Capitalized costs for the development of internal use software are included in property, plant and equipment, net on the consolidated balance sheets. Capitalized costs for internal use software are amortized on a straight-line basis over its estimated useful life, which is generally five years. Costs related to the preliminary project stage, post-implementation, training and maintenance are expensed as incurred. Costs for the development of software the Company plans to sell, lease or market on its own or as part of another product is capitalized once technological feasibility is achieved. The Company will capitalize costs until the product is ready to be sold, at which time, it will amortize the capitalized costs over the estimated useful life. As of June 30, 2023, the Company has $ 2.9 million in capitalized costs for software to be sold and it is included in other assets on the consolidated balances sheets. Impairment of Long‑Lived Assets The Company reviews long‑lived assets, including intangible assets, equity method investment in the JV, property and equipment, for impairment whenever events or changes in business circumstances indicate that the carrying amount of the assets may not be fully recoverable using pretax undiscounted cash flows. Impairment, if any, is measured as the amount by which the carrying value of a long‑lived asset exceeds its fair value. Goodwill Goodwill is not amortized but is evaluated for impairment on an annual basis and when impairment indicators are present. The Company has assessed that it has one operating segment and one reporting unit, and the consolidated net assets, including existing goodwill and other intangible assets, are considered to be the carrying value of the reporting unit. The Company estimates the fair value of the reporting unit based on the Company’s closing stock price on the trading day closest to the annual review date multiplied by the outstanding shares on that date. If the carrying value of the reporting unit is in excess of its fair value, an impairment may exist, and the Company must perform the second step of the analysis, in which the estimated fair value of the goodwill is compared to its carrying value to determine the impairment charge, if any. If the estimated fair value of the reporting unit exceeds the carrying value of the reporting unit, goodwill is not impaired and no further analysis is required. There was no impairment of goodwill identified in the fiscal years ended June 30, 2023, 2022 and 2021 . Shipping and Handling The Company’s billings for shipping and handling for product shipments to customers are included in cost of products. Shipping and handling costs incurred for inventory purchases are capitalized in inventory and expensed in cost of products. Research and Development Costs Costs related to research, design and development of products are charged to research and development expense as incurred. These costs include direct compensation, benefits, and other headcount related costs for research and development personnel, costs for materials used in research and development activities, costs for outside services, and allocated portions of facilities and other corporate costs. The Company has entered into research and clinical study arrangements with selected hospitals, cancer treatment centers, academic institutions and research institutions worldwide. These agreements support the Company’s internal research and development capabilities. Share‑Based Compensation The Company issues share‑based compensation awards to employees and directors in the form of stock options, restricted stock units (“RSUs”), performance units (“PSUs”), market stock units (“MSUs”) and employee stock purchase plan (“ESPP”) awards (collectively, “awards”). The exercise price of stock options granted is equal to the market value of the Company’s common stock on the date of grant. Share‑based compensation for stock options and ESPP awards are measured on the date of grant using a Black‑Scholes option pricing model. Share‑based compensation expense for RSUs and PSUs is measured based on the value of the Company’s common stock on the date of grant. Share-based compensation expense for MSUs is based on a Monte Carlo simulation model to estimate the grant date fair value. The Company measures and recognizes compensation expense for all stock‑based awards based on the awards’ fair value. Share‑based compensation expense for stock options, RSUs, and the ESPP awards is recognized on a straight‑line basis over the service period of the award. Share-based compensation expense for PSUs is recognized on a straight-line basis over the period of time for the performance conditions to be satisfied and only for those awards expected to vest. Forfeitures are recorded as they occur. Loss Contingencies The Company is involved in various lawsuits, claims and proceedings that arise in the ordinary course of business. The Company records a provision for a liability when it believes that it is both probable that a liability has been incurred and the amount can be reasonably estimated. Significant judgment is required to determine both probability and the estimated amount. The Company reviews these provisions quarterly and adjusts these provisions to reflect the impact of negotiations, settlements, rulings, advice of legal counsel, and updated information. Net Income (Loss) Per Common Share Basic earnings per share is computed based on the weighted average number of shares of common stock outstanding during the period. Diluted earnings per share is computed based on the weighted average number of shares of common stock plus the effect of dilutive potential common shares outstanding during the period. Dilutive potential common shares include outstanding share awards. Potentially dilutive shares of the Company’s common stock are excluded from the computation of diluted net loss per share for loss periods presented because including them would have been anti-dilutive. Dilutive earnings per share is the same as basic earnings per share for the periods in which the Company had a net loss because the inclusion of outstanding common stock would be anti-dilutive. A reconciliation of the numerator and denominator used in the calculation of basic and diluted net loss per share attributable to stockholders is as follows (in thousands): Years Ended June 30, 2023 2022 2021 Numerator: Net loss used to compute basic and diluted loss per share $ ( 9,280 ) $ ( 5,347 ) $ ( 6,311 ) Denominator: Weighted average shares used to compute basic and diluted loss per share 94,884 92,095 92,031 Basic and dilutive net loss per share $ ( 0.10 ) $ ( 0.06 ) $ ( 0.07 ) Anti-dilutive share-based awards, excluded 12,862 12,828 10,228 Outstanding Convertible Notes—Diluted Share Impact Due to the optional cash settlement feature and management’s intent to settle the principal amount thereof, in cash, the shares of common stock issuable upon conversion of the outstanding principal amount of the 3.75 % Convertible Senior Notes due 2026 and the 3.75 % Convertible Senior Notes due 2022 (collectively, the “Notes”) are included in the calculation of diluted net income (loss) per share only if their inclusion is dilutive for periods during which the Notes were outstanding. The shares of common stock issuable upon conversion of the outstanding principal amount of the Notes as of June 30, 2023, 2022 and 2021 were 17.1 million, 17.6 million and 17.6 million, respectively, and were not included in the basic and diluted net loss per common share as the effect of adding the shares were anti-dilutive. See Note 9, Debt, of the consolidated financial statements for more information about the Notes. Leases The Company is the lessee in a lease contract when the Company obtains the right to use the asset. Operating leases are included in the line items right-of-use assets, lease liabilities, current, and lease liabilities, long-term in the consolidated balance sheet. Right-of-use asset represents the Company’s right to use an underlying asset for the lease term and lease obligations represent the Company’s obligations to make lease payments arising from the lease, both of which are recognized based on the present value of the future minimum lease payments over the lease term at the commencement date. Leases with a lease term of 12 months or less at inception are not recorded on the consolidated balance sheet and are expensed on a straight-line basis over the lease term in the consolidated statements of operations. The Company determines the lease term by agreement with lessor, including lease renewal and extension. As the leases do not provide an implicit interest rate, the Company uses its incremental borrowing rate based on the information available at commencement date in determining the present value of future payments. The Company elected a practical expedient to account for lease and non-lease components together as a single lease component. Equity Method Investment The Company has an equity investment in CNNC Accuray (Tianjin) Medical Technology Co. Ltd., the Company’s JV. The Company applies the equity method of accounting to its ownership interest in the JV as the Company has the ability to exercise significant influence over the JV but lacks controlling financial interest and is not the primary beneficiary. The Company's investment in the JV is measured at cost and adjusted for the Company’s share of the JV's income or loss, for intra-entity profits and for impairment, if any. The Company recognizes its proportionate share of income or loss from the JV on a one-quarter lag due to the timing of the availability of the JV’s financial records. Profit earned by the Company from the JV is eliminated through cost of goods sold until it is realized; such profits would generally be considered realized when the inventory has been sold through to third parties . The JV's equity method goodwill is not amortized but is evaluated for impairment on an annual basis and when impairment indicators are present. Our impairment analysis considers qualitative and quantitative factors that may have a significant impact on the JV's fair value. Qualitative factors include the investee's financial condition and business outlook, industry and sector performance, operational and financing cash flow activities, and other relevant factors affecting the JV. When indicators of impairment exist, we prepare quantitative assessments of the fair value of our non-marketable equity investments, which require judgment and the use of estimates, including discount rates, investee revenue and costs, and comparable market data, among others. Income Taxes The Company is required to estimate its income taxes in each of the tax jurisdictions in which it operates prior to the completion and filing of tax returns for such periods. This process involves estimating actual current tax expense together with assessing temporary differences in the treatment of items for tax purposes versus financial accounting purposes that may create net deferred tax assets and liabilities. The Company accounts for income taxes under the asset and liability method, which requires, among other things, that deferred income taxes be provided for temporary differences between the tax bases of the Company’s assets and liabilities and their financial statement reported amounts. In addition, deferred tax assets are recorded for the future benefit of utilizing net operating losses, research and development credit carryforwards and other deferred tax assets. The Company records a valuation allowance to reduce its deferred tax assets to the amount the Company believes is more likely than not to be realized. Because of the uncertainty of the realization of the deferred tax assets, the Company has recorded a full valuation allowance against its domestic and certain foreign net deferred tax assets. The calculation of unrecognized tax benefits involves dealing with uncertainties in the application of complex global tax regulations. Management regularly assesses the Company’s tax positions in light of legislative, bilateral tax treaty, regulatory and judicial developments in the countries in which the Company does business. The Company anticipates there will be no material changes in uncertain tax positions in the next 12 months. Accumulated Other Comprehensive Income (Loss) The components of comprehensive income (loss) consist of net income (loss), changes in foreign currency exchange rate translation and net changes related to a defined benefit pension plan. The changes in foreign currency exchange rate translation and net changes related to the defined benefit pension plan are excluded from earnings and reported as a component of stockholders’ equity. The foreign currency translation adjustment results from those subsidiaries not using the United States dollar as their functional currency since the majority of their economic activities are denominated in their applicable local currency. Accordingly, all assets and liabilities related to these operations are translated at the current exchange rates at the end of each period, whereas revenues and expenses are translated at average exchange rates in effect during the period. The resulting cumulative translation adjustments are recorded directly to the accumulated other comprehensive loss account in stockholders’ equity. Recent Accounting Pronouncements Accounting Pronouncement Recently Adopted In March 2020, the FASB issued an update (“ASU 2020-04”) establishing Accounting Standards Codification (“ASC”) Topic 848, Reference Rate Reform. ASU 2020-04 contains practical expedients for reference rate reform related activities that impact debt, leases, derivatives and other contracts. This accounting standard update was effective upon issuance and must be applied prospectively by December 31, 2022. The Company’s Term Loan Facility (as de

Revenue from Contract with Customer [Abstract]
Revenue	Note 2. Revenue Contract Balances The timing of revenue recognition, billings, and cash collections results in trade receivables, unbilled receivables, and deferred revenues on the consolidated balance sheets. The Company may offer longer or extended payments of more than one year for qualified customers in some circumstances. At times, revenue recognition occurs before the billing, resulting in an unbilled receivable, which represents a contract asset. The contract asset is a component of accounts receivable and other assets for the current and non-current portions, respectively. When the Company receives advances or deposits from customers before revenue is recognized, this results in a contract liability. It can take two or more years from the time of order to revenue recognition due to the Company’s long sales cycle. Changes in the contract assets and contract liabilities are as follows (dollars in thousands): Change June 30, June 30, $ % Assets: Unbilled accounts receivable – current (1) $ 9,847 $ 13,325 ( 3,478 ) ( 26 ) Interest receivable – current (2) 379 493 ( 114 ) ( 23 ) Long-term accounts receivable (3) 4,734 5,301 ( 567 ) ( 11 ) Interest receivable – non-current (3) 673 683 ( 10 ) ( 1 ) Liabilities: Customer advances 20,777 25,290 ( 4,513 ) ( 18 ) Deferred revenue – current 72,185 75,375 ( 3,190 ) ( 4 ) Deferred revenue – non-current 27,079 24,694 2,385 10 (1) Included in accounts receivable on the consolidated balance sheets (2) Included in prepaid expenses and other current assets on the consolidated balance sheets (3) Included in other assets on the consolidated balance sheets During the year ended June 30, 2023, contract assets changed primarily due to the timing of billings that occurred after revenues were recognized, and changes in transactions with payment terms exceeding 12 months. During the year ended June 30, 2023, contract liabilities changed due to the timing of revenue recognition as a result of changes in shipping timing, transaction price, reduced customer deposits for system sales, and for which the warranty was deferred. During the years ended June 30, 2023 and June 30, 2022, the Company recognized revenues of $ 84.9 million and $ 81.2 million, respectively, which were included in the deferred revenue balances at June 30, 2022 and June 30, 2021, respectively. Remaining Performance Obligations Remaining performance obligations represent deferred revenue from open contracts, for which performance has already started and the transaction price from executed contracts, for which performance has not yet started. Service contracts in general are considered month-to-month contracts. As of June 30, 2023, total remaining performance obligations amounted to $ 1,061.7 million. Of this total amount, $ 72.2 million related to long-term warranty and non-cancellable post-warranty services, which is the estimated revenue expected to be recognized over the remaining service period and warranty period for systems that have been delivered (the time bands reflect management’s best estimate of when the Company will transfer control to the customer and may change based on timing of shipment, readiness of customers’ facilities for installation, installation requirements, and availability of products). The Company has elected the practical expedient to not disclose the unsatisfied performance obligations of contracts with an original expected duration of one year or less. The following table represents the Company's expected revenue recognition based on the remaining performance obligations related to long-term warranty and non-cancellable post-warranty services as of June 30, 2023 (in thousands): Fiscal years 2024 2025 2026 Thereafter Long-term warranty and service $ 29,796 $ 21,962 $ 13,127 $ 7,358 For the remaining $ 989.5 million of performance obligations (open systems sales, upgrades, training and other miscellaneous items), the Company estimates 27 % to 30 % will be recognized in the next 12 months, and the remaining portion will be recognized thereafter. The Company’s historical experience indicates that some of its customers will cancel or renegotiate contracts as economic conditions change or when product offerings change during the long sales cycle. The Company anticipates a portion of its open contracts may never result in revenue recognition, primarily due to the long sales cycle and factors outside of its control, including changes in customers' needs or financial condition, changes in government or health insurance reimbursement policies, or changes to regulatory requirements. Based on historical experience and management's best estimate, approximately 20 % of the Company’s $ 939.8 million open system sales contracts may never result in revenue. Capitalized Contract Costs As of June 30, 2023, and 2022, the balance of capitalized costs to obtain a contract was $ 11.0 million and $ 11.4 million, respectively. The Company has classified the capitalized costs to obtain a contract as a component of prepaid expenses and other current assets and other assets with respect to the current and non-current portions of capitalized costs, respectively, on the consolidated balance sheets. The Company recognized expenses related to the amortization of capitalized contract costs of $ 3.6 million, $ 3.3 million and $ 2.8 million, during the years ended June 30, 2023, 2022 and 2021, respectively. The Company incurred impairment losses related to capitalized contract costs of $ 0.8 million, $ 0.6 million and $ 0.6 million for the years ended June 30, 2023, 2022 and 2021 , respectively.

Supplemental Financial Information Disclosure [Abstract]
Supplemental Financial Information	Note 3. Supplemental Financial Information Consolidated Balance Sheets Financing receivables A financing receivable is a contractual right to receive money, on demand or on fixed or determinable dates, that is recognized as an asset on the Company’s balance sheets. The Company’s financing receivables, consisting of its accounts receivable with contractual maturities of more than one year, are included in other assets on the consolidated balance sheets. The Company evaluates the credit quality of a customer at contract inception and monitors credit quality over the term of the underlying transactions. The Company performs a credit analysis for all new orders and reviews payment history, current order backlog, financial performance of the customers and other variables that augment or mitigate the inherent credit risk of a particular transaction. Such variables include the underlying value and liquidity of the collateral, the essential use of the equipment, the contract term and the inclusion of credit enhancements, such as guarantees, letters of credit or security deposits. Actual cash collections may differ from the contracted maturities due to early customer buyouts, refinancing, or defaults. The Company classifies accounts as high risk when it considers the financing receivable to be impaired or when management believes there is a significant near‑term risk of non‑payment. The Company performs an assessment each quarter on the allowance for credit losses related to its financing receivables. The Company did no t have any additions to the allowance for credit losses during the years ended June 30, 2023 and 2022. A summary of the Company’s financing receivables is presented as follows (in thousands): June 30, 2023 June 30, 2022 Financing receivable $ 5,854 $ 6,137 Allowance for credit losses ( 798 ) ( 943 ) Total, net $ 5,056 $ 5,194 Reported as: Current $ 2,016 $ 2,435 Non-current 3,040 2,759 Total, net $ 5,056 $ 5,194 Inventories Inventories consisted of the following (in thousands): June 30, June 30, Raw materials $ 62,945 $ 61,871 Work-in-process 17,469 16,367 Finished goods 64,736 64,016 Total inventories $ 145,150 $ 142,254 The Company's inventories on the consolidated balance sheets are net of reserves.

These charges are cash-based charges, primarily related to severance expenses and other one-time termination benefits. At June 30, 2023 , the Company does not have any remaining accruals related to the restructuring charges.

Leases [Abstract]
Leases	Note 4. Leases The Company has operating leases for corporate offices and warehouse facilities worldwide. Additionally, the Company leases cars, copy machines and laptops that are considered operating leases. Some of the Company’s leases are non-cancellable operating lease agreements with various expiration dates through June 2035. Certain lease agreements include options to renew or terminate the lease, which are not reasonably certain to be exercised, and therefore are not factored into the determination of lease payments. In August 2022, the Company entered into a material lease agreement to extend the lease terms at its administrative and manufacturing facilities in Madison, Wisconsin through 2035. Operating lease costs during the years ended June 30, 2023, 2022, and 2021, were $ 9.4 million, $ 9.2 million and $ 9.1 million, respectively, not including short-term operating lease costs during the years ended June 30, 2023, 2022, and 2021, of $ 0.4 million, $ 0.4 million and $ 0.2 million, respectively. Cash paid for amounts included in the measurement of operating lease liabilities during the years ended June 30, 2023, 2022, and 2021, w ere $ 9.4 million, $ 9.8 million and $ 9.7 million, respectively.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Financial Instruments	Note 6. Derivative Financial Instruments The Company utilizes foreign currency forward contracts with reputable financial institutions to manage its exposure of fluctuations in foreign currency exchange rates on certain intercompany balances and foreign currency denominated cash, customer receivables and liabilities. The Company does not use derivative financial instruments for speculative or trading purposes. These forward contracts are not designated as hedging instruments for accounting purposes. Principal hedged currencies primarily include the Japanese Yen, Swiss Franc, and Euro. The periods of these forward contracts range up to approximately three months and the notional amounts are intended to be consistent with changes in the underlying exposures. The Company intends to exchange foreign currencies for U.S. Dollars at maturity. The Company enters into forward currency exchange contracts to hedge its overseas operating expenses and other liabilities when deemed appropriate. The notional amount of the Company's outstanding forward currency exchange contracts consisted of the following: As of June 30, 2023 2022 Swiss Franc 26,867 27,910 Chinese Yuan 249 2,524 Euro 17,885 16,307 British Pound 516 3,699 Indian Rupee 3,539 3,728 Japanese Yen 12,492 14,167 $ 61,548 $ 68,335 The Company entered into the foreign exchange forward contracts on June 30, 2023 and June 30, 2022, and therefore, there was no amount recorded on the balance sheets. Gains and losses on the Company's foreign currency forward contracts are recorded in Other expense, net, on the Company's consolidated statements of operations.

Fair Value Disclosures [Abstract]
Fair Value Measurements	Note 7. Fair Value Measurements Fair value is an exit price representing the amount that would be received to sell an asset or paid to transfer a liability in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. The fair value hierarchy contains three levels of inputs that may be used to measure fair value, as follows: Level 1— Unadjusted quoted prices that are available in active markets for the identical assets or liabilities at the measurement date. Level 2— Other observable inputs available at the measurement date, other than quoted prices included in Level 1, either directly or indirectly, including: • Quoted prices for similar assets or liabilities in active markets; • Quoted prices for identical or similar assets in non-active markets; • Inputs other than quoted prices that are observable for the asset or liability; and • Inputs that are derived principally from or corroborated by other observable market data. Level 3— Unobservable inputs that cannot be corroborated by observable market data and require the use of significant management judgment. These values are generally determined using pricing models for which the assumptions utilize management’s estimates of market participant assumptions. Assets and Liabilities That Are Measured at Fair Value At June 30, 2023, the Company had open currency forward contracts to purchase or sell foreign currencies with a stated, or notional, value of $ 61.5 million. The fair value of the forward contract based upon the June 30, 2023 exchange rate was $ 61.2 million, which it considers to be a Level 2 fair value measurement. At June 30, 2022, the Company had open currency forward contracts to purchase or sell foreign currencies with a stated, or notional, value of $ 68.3 million. The fair value of the forward contract based upon the June 30, 2022 exchange rate was $ 68.3 million, which it considers to be a Level 2 fair value measurement. The Company’s debt is measured on a recurring basis using Level 2 inputs based upon observable inputs of the Company’s convertible debt. The Revolving Credit Facility (as defined below) and the Term Loan Facility (as defined below) reflects the bank quoted market, which the Company considers to be a Level 2 fair value measurement. The Company believes that the carrying value of these financial instruments approximate its estimated fair value based on the effective interest rate, compared to the current market rate, available to the Company and analyzed at quarter-end. The following table summarizes the carrying value and estimated fair value of the 3.75 % Convertible Notes due 2022, the 3.75 % Convertible Notes due 2026, the Term Loan Facility, and the Revolving Credit Facility, (in thousands): June 30, 2023 June 30, 2022 Carrying Fair Value Carrying Fair Value 3.75 % Convertible Notes Due 2022 $ — $ — $ 2,863 $ 2,729 3.75 % Convertible Notes Due 2026 98,189 98,265 97,619 78,561 Term Loan Facility 69,094 69,094 74,988 74,988 Revolving Credit Facility 10,000 10,000 5,000 5,000 Total $ 177,283 $ 177,359 $ 180,470 $ 161,278

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Note 8. Commitments and Contingencies Long‑term Debt Commitments The Company is required to make semi‑annual interest payments on the 3.75 % Convertible Senior Notes due 2026, principal and interest payments on the Term Loan Facility and interest payments on the Revolving Credit Facility. See Note 9, Debt , of the consolidated financial statements for more information. Future minimum long‑term principal payments and interest on the 3.75 % Convertible Senior Notes due 2026 and Credit Facilities (as defined below), including short-term portion, as of June 30, 2023, are as follows (in thousands): Year Ending June 30, Long-Term 2024 $ 16,368 2025 17,786 2026 174,045 Total $ 208,199 (1) These amounts represent principal and interest cash payments over the contractual life of the debt obligations, including anticipated interest payments that are not recorded on the Company’s consolidated balance sheet. Any conversion, premium, redemption or purchase of the Notes that would impact cash payments is noted in the preceding table. Purchase Commitments The Company’s purchase commitments and obligations include all open purchase orders and contractual obligations in the ordinary course of business, including commitments with contract manufacturers and suppliers, for which the Company has not received the goods or services and acquisition and licensing of intellectual property. A majority of these purchase obligations are due within a year. Although open purchase orders are considered enforceable and legally binding, the terms generally allows the Company the option to cancel, reschedule, and adjust its requirements based on the Company’s business needs prior to the delivery of goods or performance of services, and hence, these purchase orders have not been included in the table above. Indemnities and Commitments The Company enters into standard indemnification agreements with its landlords and all superior mortgagees and their respective directors, officers’ agents, and employees in the ordinary course of business. Pursuant to these agreements, the Company will indemnify, hold harmless, and agree to reimburse the indemnified party for losses suffered or incurred by the indemnified party, generally the landlords, in connection with any loss, accident, injury, or damage by any third‑party with respect to the leased facilities. The term of these indemnification agreements is from the commencement of the lease agreements until termination of the lease agreements. The maximum potential amount of future payments the Company could be required to make under these indemnification agreements is unlimited; however, historically, the Company has not incurred claims or costs to defend lawsuits or settle claims related to these indemnification agreements. The Company has not recorded any liability associated with its indemnification agreements as it is not aware of any pending or threatened actions that represent probable losses as of June 30, 2023. Guarantees As of June 30, 2023 and June 30, 2022, the Company had various bank guarantees totaling approximately $ 1.3 million and $ 1.2 million, respectively, primarily related to a bidding process with customers. Royalty Agreements The Company enters into software license agreements with third parties that may require royalty payments for each license used. In connection with such agreements, the Company recorded royalty costs of $ 2.3 million, $ 1.9 million and $ 1.9 million for the years ended June 30, 2023, 2022 and 2021, respectively, which were recorded in cost of revenue or deferred cost of revenue. The Company had approximately $ 2.4 million and $ 2.4 million accrued liabilities as of June 30, 2023 and 2022, respectively, related to this agreement. Software License Indemnity Under the terms of the Company’s software license agreements with its customers, the Company agrees that in the event the software sold infringes upon any patent, copyright, trademark, or any other proprietary right of a third‑party, it will indemnify its customer licensees against any loss, expense, or liability from any damages that may be awarded against its customer. The Company includes this infringement indemnification in all of its software license agreements and selected managed services arrangements. In the event the customer cannot use the software or service due to infringement and the Company cannot obtain the right to use, replace or modify the license or service in a commercially feasible manner so that it no longer infringes, then the Company may terminate the license and provide the customer a refund of the fees paid by the customer for the infringing license or service. The Company has not recorded any liability associated with this indemnification, as it is not aware of any pending or threatened actions that represent probable losses as of June 30, 2023. Litigation From time to time, the Company is involved in legal proceedings arising in the ordinary course of its business. The Company records a provision for a loss when it believes that it is both probable that a loss has been incurred and the amount can be reasonably estimated. Currently, management believes the Company does not have any probable and reasonably estimable losses related to any current legal proceedings and claims. Although occasional adverse decisions or settlements may occur, management does not believe that an adverse determination with respect to any of these claims would individually, or in the aggregate, materially and adversely affect the Company’s financial condition or operating results. Litigation is inherently unpredictable and is subject to significant uncertainties, some of which are beyond the Company’s control. Should any of these estimates and assumptions change or prove to have been incorrect, the Company could incur significant charges related to legal matters that could have a material impact on its results of operations, financial position, and cash flows.

The aggregate principal amount of the 3.75 % Convertible Notes due 2026 totaling $ 97.1 million was issued to certain holders of the Company’s outstanding 3.75 % Convertible Notes due 2022 in exchange for approximately $ 82.1 million aggregate principal amount of 3.75 % Convertible Notes due 2022, and $ 2.9 million of 3.75 % Convertible Notes due 2026 were issued to certain other qualified new investors for cash (such transactions the “Exchange and Subscription Transactions”). Holders of the 3.75 % Convertible Notes due 2026 may convert their notes at any time on or after March 6, 2026 until the close of the business day immediately preceding the maturity date. Prior to June 6, 2026, holders of the 3.75 % Convertible Notes due 2026 may convert their notes only under certain circumstances. Upon conversion, the Company will have the right to pay cash, or deliver shares of common stock of the Company or a combination thereof, at the Company’s election. The initial conversion rate is 170.5611 shares of the Company’s common stock per $ 1,000 principal amount (which represents an initial conversion price of approximately $ 5.86 per share of the Company’s common stock). The conversion rate, and therefore, the conversion price, is subject to adjustment, as further described below. Holders of the 3.75 % Convertible Notes due 2026 who convert their notes in connection with a “make-whole fundamental change,” as defined in the indenture, may be entitled to a make-whole premium in the form of an increase in the conversion rate. Additionally, in the event of a “fundamental change,” as defined in the indenture, holders of the 3.75 % Convertible Notes due 2026 may require the Company to purchase all or a portion of their note at a fundamental change repurchase price equal to 100 % of the principal amount of the 3.75 % Convertible Notes due 2026, plus accrued and unpaid interest, if any, to, but not including, the fundamental change repurchase date. As of June 30, 2023 and June 30, 2022 , the if-converted value of the 3.75 % Convertible Notes due 2026 did not exceed the outstanding principal amount. 3.75% Convertible Senior Notes due July 2022 As of June 30, 2022, the $ 2.9 million aggregate principal amount of the 3.75 % Convertible Senior Notes due July 2022 (the “ 3.75 % Convertible Notes due 2022”) remained outstanding. In July 2022, the remaining outstanding $ 2.9 million (principal and interest) of the 3.75 % Convertible Senior Notes due 2022 was repaid in cash. Credit Facilities On May 6, 2021, the Company entered into a senior secured credit agreement (the “Credit Agreement”) with Silicon Valley Bank, individually as a lender and agent (“Agent”), and the other lenders from time to time parties thereto (together with Silicon Valley Bank as a lender, the “Lenders”), which provides for a new five-year $ 80 million term loan (the “Term Loan Facility”) and a $ 40 million revolving credit facility (the “Revolving Credit Facility” and, together with the Term Loan Facility, the “Credit Facilities”). In fiscal year 2023, interest on the borrowings under the Credit Facilities is payable in arrears on the applicable interest payment date, at an annual interest rate of reserve-adjusted, 90-day term SOFR ( subject to a 0.50 % floor) plus a margin between 2.50 % and 3.25 % margin, determined by the Consolidated Senior Net Leverage Ratio (as defined in the Credit Agreement). During the year ended June 30, 2023 , the weighted average effective interest rate on the Term Loan Facility was 7.26 % and Revolving Credit Facility was 8.27 %. The Credit Agreement requires the Company to pay the Lenders an unused commitment fee equal to the average unused portion of the Revolving Credit Facilit y. The Company pays a rate of 0.25 % to 0.40 % per annum of the average unused portion of the Revolving Credit Facility, determined by the Consolidated Senior Net Leverage Ratio (as defined in the Credit Agreement). If all or a portion of the loans under the Term Loan Facility are prepaid, then the Company will be required to pay a fee equal to 1 % of the aggregate amount of the loans so prepaid, subject to certain exceptions. The Credit Agreement contains restrictions and covenants applicable to the Company and its subsidiaries. Among other requirements, the Company may not permit the Fixed Charge Coverage Ratio (as defined in the Credit Agreement) to be less than a certain specified ratio for each fiscal quarter during the term of the Credit Agreement or the consolidated senior net leverage ratio to be greater than a certain specified ratio for each fiscal quarter during the term of the Credit Agreement. In October 2022, the Company entered into an amendment with respect of the Credit Agreement to change the requirements of the financial maintenance covenants under the Credit Agreement for the fiscal quarter ending December 31, 2022 through the end of the fiscal quarter ending June 30, 2023. As of June 30, 2023, the Company was in compliance with its covenants under the Credit Agreement. The Credit Agreement also contains customary covenants that limit, among other things, the ability of the Company and its subsidiaries to (i) incur indebtedness, (ii) incur liens on their property, (iii) pay dividends or make other distributions, (iv) sell their assets, (v) make certain loans or investments, (vi) merge or consolidate, (vii) voluntarily repay or prepay certain indebtedness and (viii) enter into transactions with affiliates, in each case subject to certain exceptions. The Credit Agreement contains customary representations and warranties and events of default.

Share-Based Payment Arrangement [Abstract]
Stock Incentive Plan and Employee Stock Purchase Plan	Note 10. Stock Incentive Plan and Employee Stock Purchase Plan As of June 30, 2023 , the Company had two outstanding stock incentive plans: the 2016 Equity Incentive Plan ( “2016 Plan”) and the 2007 Incentive Award Plan (“2007 Plan”). The 2016 Plan permits the granting of stock options, stock appreciation rights, restricted stock awards, performance shares, performance units, and RSUs. The vesting of RSUs granted under the 2016 Plan are primarily service‑based (over the requisite service period) while the vesting of performance units granted under the 2016 Plan primarily consist of PSUs or MSUs. Only employees of the Company are eligible to receive incentive stock options. Non‑employees may be granted non‑qualified stock options. Stock options granted under the 2016 Plan have an exercise price of at least 100 % of the fair market value of the underlying stock on the grant date. The stock options have 10 -year contractual terms and generally become exercisable for 25 % of the option shares one year from the date of grant and then ratably over the following 36 months. Service‑based RSUs granted generally vest 25 % of the share units covered by the grant on each of the first through fourth anniversaries of the date of the grant, subject to the continued service of the grantee through each such date. RSUs granted to the Board of Directors vest over one year. PSUs granted generally vest at the end of a three year performance period and the amount of shares that vest are based on the Company's actual performance relative to predefined performance conditions. The Board of Directors has the discretion to use different vesting schedules. As of June 30, 2023, the 2007 Plan continued to remain in effect; however, the Company can no longer grant equity awards under such plans. The following table summarizes the share‑based compensation charges included in the Company’s consolidated statements of operations and comprehensive income (loss) (in thousands): Years ended June 30, 2023 2022 2021 Cost of revenue $ 1,439 $ 1,584 $ 1,296 Research and development 1,396 1,371 1,348 Selling and marketing 1,586 2,213 1,457 General and administrative 5,632 5,432 5,231 Total $ 10,053 $ 10,600 $ 9,332 The following table summarizes the share‑based compensation charges for the Company’s equity awards (in thousands): Years ended June 30, 2023 2022 2021 Stock options $ 2,011 $ 2,565 $ 2,431 Restricted stock units 7,004 6,160 5,425 Performance stock units 54 571 — Employee stock purchase plan 984 1,304 1,374 Market stock units — — 102 Total $ 10,053 $ 10,600 $ 9,332 Stock Options The fair value of each option is estimated at the date of grant using the Black‑Scholes option pricing formula with the following assumptions: Years Ended June 30, 2023 2022 2021 Risk–free interest rate — % 2.71 % - 3.21 % 0.59 % - 1.27 % Dividend yield — % — % — % Expected term — 7.30 - 8.94 6.72 - 6.88 Expected volatility — % 54.1 % - 57.3 % 54.7 % - 55.6 % Determining Fair Value of Stock Options The fair value of each grant of stock options was determined by the Company using the methods and assumptions discussed below. Each of these inputs is subjective and generally requires significant judgment to determine. The Company estimates the fair value of its stock options using the Black‑Scholes option‑pricing model. This fair value is then amortized over the requisite service periods of the awards. The Company estimates the expected term of stock option by taking the average of the vesting term and the contractual term of the option, as illustrated by the simplified method. The expected volatility is derived from the Company’s historical stock volatility over a period approximately equal to the expected term of the options. The risk‑free interest rate is based on the U.S. Treasury constant maturity rate on the date of grant.

Equity Method Investments and Joint Ventures [Abstract]
Joint Venture	Note 11. Joint Venture In January 2019, the Company’s wholly-owned subsidiary, Accuray Asia Limited (“Accuray Asia”), entered into an agreement with CNNC High Energy Equipment (Tianjin) Co., Ltd. (the “CIRC Subsidiary”), a wholly-owned subsidiary of China Isotope & Radiation Corporation, to form a joint venture, CNNC Accuray (Tianjin) Medical Technology Co. Ltd. (the “JV”), to manufacture and sell radiation oncology systems in China. As of June 30, 2023 , the Company owned a 49 % interest in the JV, which is reported as an investment in joint venture on the Company’s consolidated balance sheets. The Company applies the equity method of accounting to its ownership interest in the JV as the Company has the ability to exercise significant influence over the JV but lacks controlling financial interest and is not the primary beneficiary. The Company recognizes the 49 % proportionate share of the JV income or loss on a one-quarter lag due to the timing of the availability of the JV’s financial records. The Company recognizes revenue on sales to the JV in the current period of control transfer, eliminating a portion of profit to the extent goods sold have not been sold through by the JV to an end customer by the end of each reporting period. The following table shows the reconciliation between the carrying value of the Company's investment in the JV and its proportional share of the underlying equity in net assets of the JV (in thousands): June 30, June 30, Carrying value of investment in joint venture $ 15,128 $ 13,879 Deferred intra-entity profit margin 5,737 5,456 Equity method goodwill ( 4,720 ) ( 4,720 ) Proportional share of equity investment in joint venture $ 16,145 $ 14,615 As of June 30, 2023, the Company’s carrying value of the investment in the JV for the Company's proportional share of the JV's currency translation adjustment was not material. At June 30, 2022 , the Company’s carrying value of the investment in the JV was increased for the Company's proportional share of the investee's currency translation adjustment by $ 1.0 million.

The federal and state carryforwards expire in varying amounts beginning in 2025 for federal and 2024 for state purposes. In addition, as of June 30, 2023 , the Company had federal and state research and development tax credits of $ 27.9 million and $ 22.6 million, respectively. If not utilized, the federal research credits will begin to expire in 2024, the California research credits have no expiration date and the other state research credits will begin to expire in 2024. Under the Internal Revenue Code (“IRC”) Sections 382 and 383, annual use of our net operating loss and research tax credit carryforwards to offset taxable income may be limited based on cumulative changes in ownership. Although ownership changes have occurred in the prior years, the carryovers should be available for utilization by the Company before they expire, provided the Company generates sufficient future taxable income. An analysis of the impact of this provision through March 31, 2022 has been performed and it was determined that no ownership change has occurred after December 2009. Based on the available objective evidence and history of losses, the Company has established a 100 % valuation allowance against its combined domestic net deferred tax assets because of uncertainty surrounding the realization of such deferred tax assets. Certain income earned by controlled foreign corporations (“CFCs”) must be included currently in the gross income of the CFC’s United States shareholder. The income required to be included in gross income is referred to as global intangible low tax income (“GILTI”) and is defined under IRC Section 951A as the excess of the shareholder’s net CFC tested income over the net deemed tangible income return. The GILTI inclusion amount has been absorbed by net operating losses. The Company has made a policy decision to record GILTI tax as a current-period expense when incurred. One of the provisions under the Tax Cuts and Jobs Act that became effective in tax years beginning after December 31, 2021 required the capitalization and amortization of research and experimental expenditures. The change in this United States tax law did not have an impact on the Company's consolidated financial statements. The Company will continue to evaluate the impact of this tax law change on future periods. At June 30, 2023, t he Company has $ 1.5 million of deferred tax liability related to withholding tax expected to be paid on the remittance of unrepatriated distributable reserves in France, Japan and Switzerland. At June 30, 2023, the Company has undistributed earnings of certain foreign subsidiaries of $ 19.8 million that it has indefinitely invested, and on which it has not recognized deferred taxes. The aggregate changes in the balance of gross unrecognized tax benefits were as follows (in thousands): Years Ended June 30, 2023 2022 2021 Balance at beginning of year $ 19,810 $ 18,765 $ 16,996 Tax positions related to current year: Additions 1,692 1,222 1,433 Tax positions related to prior years: Additions 652 61 786 Reductions ( 589 ) ( 238 ) ( 450 ) Balance at end of year $ 21,565 $ 19,810 $ 18,765 The calculation of unrecognized tax benefits involves dealing with uncertainties in the application of complex global tax regulations. Management regularly assesses the Company’s tax positions with respect to legislative, bilateral tax treaty, regulatory and judicial developments in the countries in which the Company does business. The reduction in prior year's tax positions primarily relates to lapses of applicable statutes of limitations. The Company anticipates there will be no material changes in uncertain tax positions in the next 12 months. As of June 30, 2023 , the amount of gross unrecognized tax benefits was $ 21.6 million, of which $ 21.2 million would not affect income tax expense before consideration of any valuation allowance. The Company’s practice is to recognize interest and/or penalties related to income tax matters in income tax expense. As of June 30, 2023 and 2022, the Company’s cumulative accrued interest and penalties related to uncertain tax positions, was not material. The Company files income tax returns in the United States federal, various states, and foreign jurisdictions. Due to tax attributes being carried forward and utilized during open years, the statute of limitations remains open for the U.S. federal jurisdiction and domestic states for tax years from 2002 and forward. The statutes of limitation with respect to the foreign jurisdictions where the Company files income tax returns vary from jurisdiction to jurisdiction and range from 3 to 10 years and the material foreign jurisdictions are France, Switzerland and Japan. The Company is also subject to examination of its income tax returns by the Internal Revenue Service (“IRS”) and other foreign tax authorities, and in some cases the Company has received additional tax assessments which have not been significant. The tax audit in Japan was completed in fiscal year 2023 with a tax assessment of $ 0.1 million for the 2019 to 2021 fiscal periods. The Company is under the early stages of audit by the Indian tax authorities for the fiscal year 2021.

Segment Reporting [Abstract]
Segment Disclosure	Note 14. Segment Disclosure The Company has one operating and reporting segment (oncology systems group), which develops, manufactures and markets proprietary medical devices used in radiation therapy for the treatment of cancer patients. The Company’s Chief Executive Officer, its Chief Operating Decision Maker, reviews financial information presented on a consolidated basis for purposes of making operating decisions and assessing financial performance. The Company does not assess the performance of its individual product lines on measures of profit or loss, or asset based metrics. Therefore, the information below is presented only for revenues and long‑lived tangible assets by geographic areas. Disaggregation of Revenues The Company disaggregates its revenues from contracts by geographic region, as the Company believes this best depicts how the nature, amount, timing and uncertainty of revenues and cash flows are affected by economic factors. The Company reports its customer revenues in four geographic regions: the Americas, EIMEA, Asia Pacific and Japan. The Americas region primarily includes the United States, Canada, and Latin America. The EIMEA region includes Europe, India, the Middle East and Africa. The Asia Pacific region consists of Asia, Australia and New Zealand.

The Company and its Significa_2

The Company and its Significant Accounting Policies (Policies)	12 Months Ended
	Jun. 30, 2023
Basis of Presentation and Principles of Consolidation	Basis of Presentation and Principles of Consolidation The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All significant intercompany transactions and balances have been eliminated in consolidation. The accompanying consolidated financial statements have been prepared in accordance with United States generally accepted accounting principles (“U.S. GAAP”), pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”).
Reclassifications	Reclassifications Certain amounts on the consolidated statements of cash flows and consolidated statements of stockholders equity in prior periods have been reclassified to conform to current year presentation.
Risks and Uncertainties	Risks and Uncertainties The Company is subject to risks and uncertainties caused by events with significant geopolitical and macroeconomic impacts, including, but not limited to, the COVID-19 pandemic, the Russian invasion of Ukraine, inflation, actions taken to counter inflation, foreign currency exchange rate fluctuations and instability in the banking sector. The Company is also continuing to navigate supply chain and inflation challenges and foreign exchange continues to be a significant headwind that affects the Company’s results of operations. These ongoing supply chain challenges and heightened logistics costs have adversely affected the Company's gross margins and net income or loss, and the Company’s current expectations are that gross margins and net income or loss will continue to be adversely affected by increased material costs and freight and logistic expenses through at least fiscal year 2024, if not longer. Furthermore, certain parts required for the manufacturing and servicing of the Company's products, such as electronic components, are scarce and becoming increasingly difficult to source, even at increased prices. If such parts become unavailable to the Company, it would not be able to manufacture or service our products, which would adversely impact revenue, gross margins, and net income or (loss). The Company expects that the business of its customers and its own business will continue to be adversely impacted, directly or indirectly, by macroeconomic and geopolitical issues, including supply chain issues, inflation, labor, foreign currency exchange rate fluctuations, uncertainty and volatility in the banking and financial services sector, tightening credit markets, the effects of the COVID-19 related restrictions, and other factors that may emerge. The extent of the ongoing impact of these macroeconomic events on our business, our markets and on global economic activity however, is uncertain and the related financial impact cannot be reasonably estimated with any certainty at this time. The Company continues to critically review its liquidity and anticipated capital requirements in light of the significant uncertainty created by geopolitical and macroeconomic conditions. Based on the Company’s cash and cash equivalents balance, available debt facilities, current business plan and revenue prospects, the Company believes that it will have sufficient cash resources and anticipated cash flows to fund its operations for at least the next 12 months. The Company however, is unable to predict with certainty the impact of geopolitical and macroeconomic conditions, including its effect on global supply chain and logistics, will have on its ability to maintain compliance with the debt covenants contained in the credit agreement related to its Credit Facilities (as such terms are defined in Note 9 below), including financial covenants regarding the consolidated fixed charge coverage ratio and consolidated senior net leverage ratio. The Company was in compliance with such covenants at June 30, 2023. Following June 30, 2023, our financial maintenance covenants under the Existing Credit Agreement will become more stringent and, as a result could be more difficult to comply with. These restrictions could adversely affect the Company’s ability to finance its future operations or capital needs, withstand a future downturn in its business or the economy in general, engage in business activities, including future opportunities that may be in its interest, and plan for or react to market conditions or otherwise execute its business strategies. The Company’s ability to comply with the covenants and other terms governing the Credit Facilities will depend in part on its future operating performance. In addition, because substantially all of the Company’s assets are pledged as a security under the Credit Facilities, if the Company is not able to cure any default or repay outstanding borrowings, such assets are subject to the risk of foreclosure by the Company’s lenders. Failure to meet the covenant requirements in the future could cause the Company to be in default and the maturity of the related debt could be accelerated and become immediately payable. This may require the Company to obtain waivers or amendments to the credit agreement in order to maintain compliance and there can be no certainty that any such waiver or amendment will be available, or what the cost of such waiver or amendment, if obtained, would be. If the Company is unable to obtain necessary waivers or amendment and the debt under such credit facility is accelerated, the Company would be required to obtain replacement financing at prevailing market rates, which may not be favorable to the Company. There is no guarantee that the Company would be able to satisfy its obligations if any of its indebtedness is accelerated .
Use of Estimates	Use of Estimates The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues, expenses, and related disclosures at the date of the financial statements. The Company assessed certain accounting matters that generally require consideration of forecasted financial information in context with the information reasonably available to the Company. A ctual results could differ materially from those estimates.
Foreign Currency	Foreign Currency The Company’s international subsidiaries use their local currencies as their functional currencies. For those subsidiaries, assets and liabilities are translated at exchange rates in effect at the balance sheet date and income and expense accounts at the average exchange rate. Resulting translation adjustments are excluded from the determination of net income or loss and are recorded in accumulated other comprehensive income (loss) as a separate component of stockholders’ equity. Net foreign currency exchange transaction gains or losses are included as a component of other expense, net, in the Company’s consolidated statements of operations and comprehensive income (loss).
Cash, Cash Equivalents and Restricted Cash	Cash, Cash Equivalents and Restricted Cash 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. Cash and cash equivalents are held in various financial institutions in the United States and internationally. Restricted cash primarily consists of cash that is temporarily held in bank accounts which are under the control of the lender to the Credit Facilities, ce rtificates of deposit held as guarantees in connection with customer contracts and corporate leases as well as funds held as guarantees for Value‑Added Tax (“VAT”) obligations in a foreign jurisdiction.
Fair Value Measurements	Fair Value Measurements The carrying values of the Company’s financial instruments including cash equivalents, restricted cash, accounts receivable, accounts payable, and the Credit Facilities, are approximately equal to their respective fair values due to the relatively short‑term nature of these instruments. See Note 7, Fair Value Measurements, of the consolidated financial statements for further information.
Concentration of Credit Risk and Other Risks and Uncertainties	Concentration of Credit Risk and Other Risks and Uncertainties The Company’s cash and cash equivalents are primarily deposited with several major financial institutions. At times, deposits in these institutions exceed the amount of insurance provided on such deposits. The Company has not experienced any losses in such accounts and believes that it is not exposed to any significant risk on these balances. The Company performs ongoing credit evaluations of its customers and maintains reserves for potential credit losses. Accounts receivable are deemed past due in accordance with the contractual terms of the agreement. The Company maintains an allowance for doubtful accounts based upon the expected collectability of all accounts receivable. Historically, such losses have been within management’s expectations. The Company h ad one customer that represented 10 % or more of total net revenue for the years ended June 30, 2023, 2022, and 2021 , respectively. The Company had one customer a s of June 30, 2023 and two customers as of June 30, 2022 , respectively, that each accounted for more than 10 % of accounts receivable, net. Single‑source suppliers presently provide the Company with several components. In most cases, if a supplier was unable to deliver these components, the Company believes that it would be able to find other sources for these components subject to any regulatory qualifications, if required.
Inventories	Inventories Inventories are stated at the lower of cost (on a first‑in, first‑out basis) or net realizable value. Excess and obsolete inventories are written down based on historical sales and forecasted demand, as judged by management.
Revenue Recognition	Revenue Recognition The Company’s revenue consists of product revenue resulting from the sale of systems, system upgrades and service revenue. The Company accounts for a contract with a customer when there is a legally enforceable contract between the Company and its customer, the rights of the parties are identified, the contract has commercial substance, and collectability of the contract consideration is probable. The Company’s revenues are measured based on the consideration specified in the contract with each customer, net of any discounts and taxes collected from customers that are remitted to government authorities. The Company’s revenue is primarily derived from sales of CyberKnife and TomoTherapy platforms and services, which include post-contract customer support (“PCS”), installation services, training and other professional services. The majority of the Company's revenue arrangements consist of multiple performance obligations, which can include system, upgrades, installation, training, services, construction, and consumables. For bundled arrangements, the Company accounts for individual products and services separately if a product or service is separately identifiable from other items in the bundled package and if a customer can benefit from it on its own or with other resources that are readily available to the customer. The Company’s products are generally sold without a right of return, and the Company’s contracts generally provide a fixed transaction price. The Company may offer incentives in the form of discounts, including volume system discounts, which are included in the contract and used to calculate the final fixed price of the arrangement. These discounts may pertain to all performance obligations in a specific contract or may be allocated to a specific performance obligation. The Company reviews payment terms extending beyond one year. If it is determined that a material financing component exists, we recognize this as interest income over time. The Company applies the practical expedient to not adjust for a material financing component if the gap between payment and delivery was expected, at the contract inception, to be less than one year. The Company offers customers the opportunity to trade in their older systems for a discount off the purchase of a new system. The Company generally does not provide specific trade-in prices or upgrade rights at the time of purchase of the original system. Trade-in or upgrade transactions are based on the then fair value of the system and are separately negotiated, taking into consideration circumstances existing at the time of the trade-in or upgrade. Accordingly, implied trade-ins and upgrades discounts are not considered separate performance obligations in system sales agreements. During fiscal years 2023, 2022 and 2021, no fair value has been assigned to any of the systems that were traded-in. The SSP of performance obligations is determined based on observable prices at which the Company separately sells the products and services. If the SSP is not directly observable, then the Company estimates the SSP considering market conditions, entity-specific factors, and information about the customer or class of customer that is reasonably available. The contract consideration allocation is based on the SSP at contract inception. The consideration (net of any discounts) is allocated among separate products and services in a bundle based on their relative SSPs. Contract modifications typically add additional goods or services or change pricing. For such modifications, the most recent SSP is used for reallocation to the remaining performance obligations. The Company recognizes revenue for certain performance obligations at the point in time when control is transferred, such as the delivery of products and upgrades. Service revenue is recognized over the term of the service period as the customer benefits from the services throughout the service period. Revenue related to services that are not part of a service contract and performed on a time-and-materials basis are recognized when performed. Service contracts comprise a single stand-ready performance obligation satisfied over time as our customers simultaneously receive and consume benefits from the Company's performance. This performance obligation constitutes a series of services that are substantially the same and provided over time using the same measure of progress. Revenues derived from these arrangements are recognized over time using an output method based upon the passage of time as this provides a faithful depiction of the pattern of transfer of control. The Company recognizes an asset for the incremental costs of obtaining a contract with a customer when the Company expects to generate future economic benefits from the related revenue-generating contracts. The Company capitalizes incremental contract acquisition costs, and amortizes such costs over a five year period, the period which the Company expects to benefit, based on historical service renewal rates, and expectations of future customer renewals. Most of the Company’s contract costs are associated with its internal sales force compensation program and a portion of its employee bonus program. The Company capitalizes and amortizes the incremental costs of obtaining a contract, primarily related to certain bonuses and sales commissions. The capitalized bonuses and sales commissions are amortized over a period of five years commencing upon the initial transfer of control of the system to the customer. The pattern of amortization is commensurate with the pattern of transfer of control of the performance obligations to the customer. The amortization of these contract assets is included in cost of sales, research and development, sales and marketing, and general and administrative expenses based on department headcount allocations in the consolidated statements of operations. The Company elected to use the practical expedient and expense as incurred commissions related to service renewals and upgrades because the amortization period is one year or less. The Company invoices its customers based on the billing schedules in its sales arrangements. Payment terms vary from 30 to 90 days, or longer, from the date of invoice. Contract assets for the periods presented primarily represent the difference between the revenue that was recognized based on the relative standalone selling price of the related performance obligations satisfied, and the contractual billing terms. Deferred revenue for periods presented primarily relates to service contracts where the service fees are billed up-front, generally quarterly or annually, prior to services being performed. The associated deferred revenue is generally recognized over the term of the service period. The Company did not have any significant impairment losses on its contract assets for any period presented.
Deferred Revenue and Customer Advances	Deferred Revenue and Customer Advances Deferred revenue primarily consists of unfulfilled obligations from open contracts for which performance has already started including short-shipped items, deferred warranty, training, maintenance services and other unperformed or incomplete performance obligations. Service contracts outside of the warranty period, for maintenance services, in general, are considered month-to-month contracts. Deferred revenue includes deferred warranty expected to be recognized over the remaining warranty period for systems already installed. Customer advances represent payments made by customers in advance of product shipment.
Property and Equipment	Property and Equipment Property and equipment are stated at cost and are depreciated using the straight‑line method over the estimated useful lives of the related assets. Leasehold improvements are depreciated on a straight‑line basis over the remaining term of the lease or the estimated useful life of the asset, whichever is shorter. Machinery and equipment are depreciated over five years . Furniture and fixtures are depreciated over four years . Computer and office equipment and computer software are depreciated over three years . Repairs and maintenance costs, which are not considered improvements and do not extend the useful life of the property and equipment, are expensed as incurred.
Software Capitalization Costs	Software Capitalization Costs Costs for the development of new software products and the substantial enhancements to existing software products for internal use are capitalized when it is considered probable that the software will be fully developed and used to perform its intended function. Capitalized costs for the development of internal use software are included in property, plant and equipment, net on the consolidated balance sheets. Capitalized costs for internal use software are amortized on a straight-line basis over its estimated useful life, which is generally five years. Costs related to the preliminary project stage, post-implementation, training and maintenance are expensed as incurred. Costs for the development of software the Company plans to sell, lease or market on its own or as part of another product is capitalized once technological feasibility is achieved. The Company will capitalize costs until the product is ready to be sold, at which time, it will amortize the capitalized costs over the estimated useful life. As of June 30, 2023, the Company has $ 2.9 million in capitalized costs for software to be sold and it is included in other assets on the consolidated balances sheets.
Impairment of Long-Lived Assets	Impairment of Long‑Lived Assets The Company reviews long‑lived assets, including intangible assets, equity method investment in the JV, property and equipment, for impairment whenever events or changes in business circumstances indicate that the carrying amount of the assets may not be fully recoverable using pretax undiscounted cash flows. Impairment, if any, is measured as the amount by which the carrying value of a long‑lived asset exceeds its fair value.
Goodwill	Goodwill Goodwill is not amortized but is evaluated for impairment on an annual basis and when impairment indicators are present. The Company has assessed that it has one operating segment and one reporting unit, and the consolidated net assets, including existing goodwill and other intangible assets, are considered to be the carrying value of the reporting unit. The Company estimates the fair value of the reporting unit based on the Company’s closing stock price on the trading day closest to the annual review date multiplied by the outstanding shares on that date. If the carrying value of the reporting unit is in excess of its fair value, an impairment may exist, and the Company must perform the second step of the analysis, in which the estimated fair value of the goodwill is compared to its carrying value to determine the impairment charge, if any. If the estimated fair value of the reporting unit exceeds the carrying value of the reporting unit, goodwill is not impaired and no further analysis is required. There was no impairment of goodwill identified in the fiscal years ended June 30, 2023, 2022 and 2021 .
Shipping and Handling	Shipping and Handling The Company’s billings for shipping and handling for product shipments to customers are included in cost of products. Shipping and handling costs incurred for inventory purchases are capitalized in inventory and expensed in cost of products.
Research and Development Costs	Research and Development Costs Costs related to research, design and development of products are charged to research and development expense as incurred. These costs include direct compensation, benefits, and other headcount related costs for research and development personnel, costs for materials used in research and development activities, costs for outside services, and allocated portions of facilities and other corporate costs. The Company has entered into research and clinical study arrangements with selected hospitals, cancer treatment centers, academic institutions and research institutions worldwide. These agreements support the Company’s internal research and development capabilities.
Share-Based Compensation	Share‑Based Compensation The Company issues share‑based compensation awards to employees and directors in the form of stock options, restricted stock units (“RSUs”), performance units (“PSUs”), market stock units (“MSUs”) and employee stock purchase plan (“ESPP”) awards (collectively, “awards”). The exercise price of stock options granted is equal to the market value of the Company’s common stock on the date of grant. Share‑based compensation for stock options and ESPP awards are measured on the date of grant using a Black‑Scholes option pricing model. Share‑based compensation expense for RSUs and PSUs is measured based on the value of the Company’s common stock on the date of grant. Share-based compensation expense for MSUs is based on a Monte Carlo simulation model to estimate the grant date fair value. The Company measures and recognizes compensation expense for all stock‑based awards based on the awards’ fair value. Share‑based compensation expense for stock options, RSUs, and the ESPP awards is recognized on a straight‑line basis over the service period of the award. Share-based compensation expense for PSUs is recognized on a straight-line basis over the period of time for the performance conditions to be satisfied and only for those awards expected to vest. Forfeitures are recorded as they occur.
Loss Contingencies	Loss Contingencies The Company is involved in various lawsuits, claims and proceedings that arise in the ordinary course of business. The Company records a provision for a liability when it believes that it is both probable that a liability has been incurred and the amount can be reasonably estimated. Significant judgment is required to determine both probability and the estimated amount. The Company reviews these provisions quarterly and adjusts these provisions to reflect the impact of negotiations, settlements, rulings, advice of legal counsel, and updated information.
Net Income (Loss) Per Common Share	Net Income (Loss) Per Common Share Basic earnings per share is computed based on the weighted average number of shares of common stock outstanding during the period. Diluted earnings per share is computed based on the weighted average number of shares of common stock plus the effect of dilutive potential common shares outstanding during the period. Dilutive potential common shares include outstanding share awards. Potentially dilutive shares of the Company’s common stock are excluded from the computation of diluted net loss per share for loss periods presented because including them would have been anti-dilutive. Dilutive earnings per share is the same as basic earnings per share for the periods in which the Company had a net loss because the inclusion of outstanding common stock would be anti-dilutive. A reconciliation of the numerator and denominator used in the calculation of basic and diluted net loss per share attributable to stockholders is as follows (in thousands): Years Ended June 30, 2023 2022 2021 Numerator: Net loss used to compute basic and diluted loss per share $ ( 9,280 ) $ ( 5,347 ) $ ( 6,311 ) Denominator: Weighted average shares used to compute basic and diluted loss per share 94,884 92,095 92,031 Basic and dilutive net loss per share $ ( 0.10 ) $ ( 0.06 ) $ ( 0.07 ) Anti-dilutive share-based awards, excluded 12,862 12,828 10,228 Outstanding Convertible Notes—Diluted Share Impact Due to the optional cash settlement feature and management’s intent to settle the principal amount thereof, in cash, the shares of common stock issuable upon conversion of the outstanding principal amount of the 3.75 % Convertible Senior Notes due 2026 and the 3.75 % Convertible Senior Notes due 2022 (collectively, the “Notes”) are included in the calculation of diluted net income (loss) per share only if their inclusion is dilutive for periods during which the Notes were outstanding. The shares of common stock issuable upon conversion of the outstanding principal amount of the Notes as of June 30, 2023, 2022 and 2021 were 17.1 million, 17.6 million and 17.6 million, respectively, and were not included in the basic and diluted net loss per common share as the effect of adding the shares were anti-dilutive. See Note 9, Debt, of the consolidated financial statements for more information about the Notes.
Leases	Leases The Company is the lessee in a lease contract when the Company obtains the right to use the asset. Operating leases are included in the line items right-of-use assets, lease liabilities, current, and lease liabilities, long-term in the consolidated balance sheet. Right-of-use asset represents the Company’s right to use an underlying asset for the lease term and lease obligations represent the Company’s obligations to make lease payments arising from the lease, both of which are recognized based on the present value of the future minimum lease payments over the lease term at the commencement date. Leases with a lease term of 12 months or less at inception are not recorded on the consolidated balance sheet and are expensed on a straight-line basis over the lease term in the consolidated statements of operations. The Company determines the lease term by agreement with lessor, including lease renewal and extension. As the leases do not provide an implicit interest rate, the Company uses its incremental borrowing rate based on the information available at commencement date in determining the present value of future payments. The Company elected a practical expedient to account for lease and non-lease components together as a single lease component.
Equity Method Investment	Equity Method Investment The Company has an equity investment in CNNC Accuray (Tianjin) Medical Technology Co. Ltd., the Company’s JV. The Company applies the equity method of accounting to its ownership interest in the JV as the Company has the ability to exercise significant influence over the JV but lacks controlling financial interest and is not the primary beneficiary. The Company's investment in the JV is measured at cost and adjusted for the Company’s share of the JV's income or loss, for intra-entity profits and for impairment, if any. The Company recognizes its proportionate share of income or loss from the JV on a one-quarter lag due to the timing of the availability of the JV’s financial records. Profit earned by the Company from the JV is eliminated through cost of goods sold until it is realized; such profits would generally be considered realized when the inventory has been sold through to third parties . The JV's equity method goodwill is not amortized but is evaluated for impairment on an annual basis and when impairment indicators are present. Our impairment analysis considers qualitative and quantitative factors that may have a significant impact on the JV's fair value. Qualitative factors include the investee's financial condition and business outlook, industry and sector performance, operational and financing cash flow activities, and other relevant factors affecting the JV. When indicators of impairment exist, we prepare quantitative assessments of the fair value of our non-marketable equity investments, which require judgment and the use of estimates, including discount rates, investee revenue and costs, and comparable market data, among others.
Income Taxes	Income Taxes The Company is required to estimate its income taxes in each of the tax jurisdictions in which it operates prior to the completion and filing of tax returns for such periods. This process involves estimating actual current tax expense together with assessing temporary differences in the treatment of items for tax purposes versus financial accounting purposes that may create net deferred tax assets and liabilities. The Company accounts for income taxes under the asset and liability method, which requires, among other things, that deferred income taxes be provided for temporary differences between the tax bases of the Company’s assets and liabilities and their financial statement reported amounts. In addition, deferred tax assets are recorded for the future benefit of utilizing net operating losses, research and development credit carryforwards and other deferred tax assets. The Company records a valuation allowance to reduce its deferred tax assets to the amount the Company believes is more likely than not to be realized. Because of the uncertainty of the realization of the deferred tax assets, the Company has recorded a full valuation allowance against its domestic and certain foreign net deferred tax assets. The calculation of unrecognized tax benefits involves dealing with uncertainties in the application of complex global tax regulations. Management regularly assesses the Company’s tax positions in light of legislative, bilateral tax treaty, regulatory and judicial developments in the countries in which the Company does business. The Company anticipates there will be no material changes in uncertain tax positions in the next 12 months.
Accumulated Other Comprehensive Income (Loss)	Accumulated Other Comprehensive Income (Loss) The components of comprehensive income (loss) consist of net income (loss), changes in foreign currency exchange rate translation and net changes related to a defined benefit pension plan. The changes in foreign currency exchange rate translation and net changes related to the defined benefit pension plan are excluded from earnings and reported as a component of stockholders’ equity. The foreign currency translation adjustment results from those subsidiaries not using the United States dollar as their functional currency since the majority of their economic activities are denominated in their applicable local currency. Accordingly, all assets and liabilities related to these operations are translated at the current exchange rates at the end of each period, whereas revenues and expenses are translated at average exchange rates in effect during the period. The resulting cumulative translation adjustments are recorded directly to the accumulated other comprehensive loss account in stockholders’ equity.
Accounting Pronouncement Recently Adopted
Recent Accounting Pronouncements	Recent Accounting Pronouncements Accounting Pronouncement Recently Adopted In March 2020, the FASB issued an update (“ASU 2020-04”) establishing Accounting Standards Codification (“ASC”) Topic 848, Reference Rate Reform. ASU 2020-04 contains practical expedients for reference rate reform related activities that impact debt, leases, derivatives and other contracts. This accounting standard update was effective upon issuance and must be applied prospectively by December 31, 2022. The Company’s Term Loan Facility (as defined below) and Revolving Credit Facility (as defined below) previously applied the Eurodollar rate London Interbank Offer Rate (“LIBOR”) to the variable component of the interest rate, but has moved away from the Eurodollar rate LIBOR in connection with reference rate reform. In October 2022, the Company began using the Secured Overnight Financing Rate (“SOFR”) to calculate the variable component of the interest rate for its Term Loan Facility and Revolving Credit Facility. The change to using SOFR did not have a material impact on the Company's financial statements.
