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 has its principal place of business in Sunnyvale, California. The Company has primary offices in the United States, Switzerland, China, Hong Kong and Japan and conducts its business worldwide. Basis of Presentation The unaudited condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All significant inter-company transactions and balances have been eliminated in consolidation. The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with United States generally accepted accounting principles (“GAAP”), pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”). Certain information and note disclosures have been condensed or omitted pursuant to such rules and regulations. The unaudited condensed consolidated financial statements have been prepared on the same basis as the annual financial statements and, in the opinion of management, reflect all adjustments, which include only normal recurring adjustments, necessary for a fair presentation of the periods presented. The results for the three and six months ended December 31, 2021 are not necessarily indicative of the results to be expected for the fiscal year ending June 30, 2022, or for any other future interim period or fiscal year. These unaudited condensed consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements and accompanying notes for the fiscal year ended June 30, 2021 included in the Company’s Annual Report on Form 10-K filed with the SEC on August 17, 2021. Risks and Uncertainties The Company is subject to risks and uncertainties as a result of a novel strain of coronavirus, severe acute respiratory syndrome coronavirus 2, or SARS-CoV-2, which causes coronavirus disease 2019 (“COVID-19”) and has resulted in a worldwide pandemic. The extent of the impact of the COVID-19 pandemic on the Company's business is highly uncertain and difficult to predict, as the effects of and response to the pandemic are rapidly evolving and new information is regularly coming to light, particularly as new COVID-19 variants emerge. The Company's customers are diverting resources to treat COVID-19 patients and deferring non-urgent and elective procedures. Some customers, which include hospitals, major academic medical centers, and other related entities, have incurred significant losses during the COVID-19 pandemic due to reduced patient volume. These impacts on our customers may adversely affect their ability to meet their financial and other contractual obligations, including to the Company. Furthermore, global economic uncertainty, including labor shortages, related to the COVID-19 pandemic may result in an incremental adverse impact on revenue, net income (loss) and cash flow and may require significant additional expenditures or cost-cutting to mitigate such impacts. Policymakers around the globe have responded with fiscal policy actions to support the healthcare industry and economy as a whole. The magnitude and overall effectiveness of these actions remain uncertain. The Company’s financial results have also been affected by the COVID-19 pandemic in various ways. The COVID-19 pandemic is adversely impacting the pace at which the Company’s backlog converts to revenue. This is primarily the result of pandemic-related delays in the timing of deliveries and installations, which has adversely affected our revenue. The Company has experienced such delays in deliveries and installations since the third quarter of fiscal year 2020 and expects that such delays in will continue at least through the end of fiscal 2022 if not longer, which could have a negative impact on revenue. The Company has experienced disruptions in its sales cycle as well as delays in customer payments and service agreements. The Company also received requests from a few customers to extend payment terms or temporarily suspend service and corresponding payment obligations. While the Company has only received a small number of requests thus far, there can be no guarantee that more customers will not ask for the same in the future. In addition, as the COVID-19 pandemic continues to impact the global supply chain, disruptions in parts of our supply chain have resulted in delays in the receipt of certain components for our products as well as increased pricing pressure for such parts. These ongoing supply chain challenges and heightened logistics costs have adversely affected our gross margins and net income (loss), and the Company’s current expectations are that gross margins and net income (loss) will continue to be adversely affected by increased material costs and freight and logistic expenses through at least the remainder of the fiscal year 2022, if not longer. Furthermore, certain parts required for the manufacture and servicing of our products, such as electronic components, are scarce and becoming increasingly difficult to source even at increased prices. If such parts become unavailable to us, we would not be able to manufacture or service our products, which would adversely impact revenue, gross margins, and net income (loss). As a result, the Company is carefully monitoring the pandemic and the potential length and depth of the resulting economic impact on our financial condition and results of operations. There remain uncertainties around the spread, severity and potential resurgence of COVID-19, the impact of new COVID-19 variants, vaccination deployment efforts, and how long the pandemic and associated health measures will last, the related financial impact cannot be reasonably estimated at this time, although the impacts are expected to continue and may significantly affect the Company’s business. The Company continues to critically review its liquidity and anticipated capital requirements in light of the significant uncertainty created by the COVID-19 pandemic. 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. However, the Company is unable to predict with certainty the impact of the COVID-19 pandemic, 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 10 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 December 31, 2021. 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 and the unknown future impacts of the COVID-19 pandemic. Key estimates and assumptions made by the Company relate to revenue recognition and the assessment of stand-alone selling price (“SSP”), assessment of recoverability of goodwill and intangible assets, valuation of our equity method investment in the JV, valuation of inventories, annual performance related bonuses, allowance for credit losses and loss contingencies. Actual results could differ materially from those estimates. Significant Accounting Policies Other than the policy adoption discussed below under Accounting Pronouncements Recently Adopted, there have been no changes in the Company’s significant accounting policies during the six months ended December 31, 2021 compared to the significant accounting policies described in its Annual Report on Form 10-K for the fiscal year ended June 30, 2021 .

Organization Consolidation And Presentation Of Financial Statements [Abstract]
Recent Accounting Pronouncements	Note 2. Recent Accounting Pronouncements Accounting Pronouncement Recently Adopted In December 2019, the FASB issued ASU No. 2019-12, Income Taxes (Topic 740): Simplifying Accounting for Income Taxes (“ASU 2019-12”). The amendments in ASU 2019-12 are intended to simplify various aspects related to accounting for income taxes and reduce the cost of accounting for income taxes. ASU 2019-12 removes certain exceptions to the general principles in Topic 740 and also clarifies and amends existing guidance to improve consistent application. The Company adopted ASU 2019-12 on July 1, 2021. The adoption of this standard did not have a material impact on its consolidated financial statements. In January 2020, the FASB issued ASU 2020-01 Investments-Equity Securities (Topic 321), Investments-Equity Method and Joint Ventures (Topic 323), and Derivatives and Hedging (Topic 815) - Clarifying the Interactions between Topic 321, Topic 323, and Topic 815. This guidance addresses accounting for the transition into and out of the equity method and provides clarification of the interaction of rules for equity securities, the equity method of accounting, and forward contracts and purchase options on certain types of securities. This standard is effective for fiscal years and interim periods within those fiscal years beginning after December 15, 2020. The Company adopted ASU 2020-01 on July 1, 2021. The adoption of this standard did not have a material impact on its consolidated financial statements. In August 2020, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update (“ASU”) No. 2020-06 , Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging—Contracts in Entity’s Own Equity (Subtopic 815-40). Under ASU No. 2020-06, the embedded conversion features are no longer separated from the host contract for convertible instruments with conversion features that are not required to be accounted for as derivatives under Topic 815, or that do not result in substantial premiums accounted for as paid-in capital. Consequently, a convertible debt instrument will be accounted for as a single liability measured at its amortized cost, as long as no other features require bifurcation and recognition as derivatives. The new guidance also requires the if-converted method to be applied for all convertible instruments when calculating diluted earnings per share. The Company adopted this standard effective July 1, 2021, using a modified retrospective method, under which financial results reported in prior periods were not adjusted. The Company applied the provisions of this guidance to our 3.75 % convertible senior notes due June 2026 (“2026 Notes”). Upon adoption, the Company recorded an increase to Accumulated deficit of $ 0.8 million, a decrease to Additional paid-in capital of $ 25.6 million and an increase to Debt of $ 24.8 million. There was no impact to diluted loss per share as the inclusion of potential shares of common stock related to the 2026 Notes would have been anti-dilutive. For further information, see Note 10, Debt. In October 2020, the FASB issued ASU 2020-10, Codification Improvements - Disclosures. This ASU improves consistency by amending the codification to include all disclosure guidance in the appropriate disclosure sections and clarifies application of various provisions in the codification by amending and adding new headings, cross referencing to other guidance, and refining or correcting terminology. This ASU is effective for fiscal years beginning after December 15, 2020. This ASU will not affect the Company's results of operations, cash flows or financial position. The adoption of ASU No. 2020-10 by the Company effective July 1, 2021 did not have a material impact on the Company’s financial statements or disclosures. Accounting Pronouncements Not Yet Effective 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. The guidance in ASU 2020-04 is optional and may be elected over time as reference rate reform activities occur. The Company’s Term Loan Facility and Revolving Credit Facility applies Eurodollar rate LIBOR to the variable component of the interest rate, if a Benchmark transition event, or an early opt-in election, as applicable occurred a transition to the use of the Secured Overnight Financing Rate ("SOFR") to replace such rate. The Company is currently evaluating the impact of the guidance and our options related to the practical expedients. In October 2021, the FASB issued ASU No. 2021-08, Accounting for Contract Assets and Contract Liabilities from Contracts with Customers. The amendment addresses how to account for contract assets recognized under Topic 606 in a business combination. This standard is effective for fiscal years and interim periods within those fiscal years beginning after December 15, 2022. The Company is currently evaluating the impact ASU 2021-08 will have on its financial statements.

Revenue

Revenue From Contract With Customer [Abstract]
Revenue	Note 3. Revenue Contract Balances The timing of revenue recognition, billings, and cash collections results in trade and 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 up to two and half 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: December 31, June 30, (Dollars in thousands) Amount Amount Contract Assets: Unbilled accounts receivable – current (1) $ 11,447 $ 12,354 Interest receivable – current (2) 534 512 Long-term accounts receivable (3) 5,118 4,970 Interest receivable – non-current (3) 844 1,083 Contract Liabilities: Customer advances 24,610 24,937 Deferred revenue – current 76,585 81,660 Deferred revenue – non-current 25,175 23,685 (1) Included in accounts receivable on the Company’s consolidated balance sheet (2) Included in prepaid expenses and other current assets on the Company’s consolidated balance sheet (3) Included in other assets on the Company’s consolidated balance sheet During the quarter ended December 31, 2021, contract assets changed primarily due to changes in the timing of billings that occurred after revenues were recognized and changes in transactions with payment terms exceeding 12 months. Contract liabilities changed due to changes in the timing of recognition of revenue for system sales for which the warranty has not yet started and was deferred and due to changes in transaction price. During the three and six months ended December 31, 2021, the Company recognized revenues of $ 22.3 million and $ 55.8 million, respectively, which were included in the deferred revenues balances at June 30, 2021. During the three and six months ended December 31, 2020, the Company recognized revenues of $ 8.4 million and $ 17.2 million, respectively, which were included in the deferred revenues balances at June 30, 2020. 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 December 31, 2021 , total remaining performance obligations amounted to $ 1,102.7 million. Of this total amount, $ 70.5 million related to long-term warranty and service, such as non cancellable post contract services and system warranty, which is expected to be recognized over the remaining service period and warranty period for systems that have been delivered, respectively. The following table represents the Company's remaining performance obligations related to long-term warranty and non cancellable post warranty services as of December 31, 2021 and the estimated revenue expected to be recognized (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). Fiscal years of revenue recognition (Dollars in thousands) 2022 2023 2024 Thereafter Long-term warranty and service $ 16,584 $ 25,674 $ 15,130 $ 13,149 For the remaining $ 1,032.2 million of performance obligations, the Company estimates 21 % to 29 % 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, approximately 23 % of the Company’s $ 1,032.2 million open contracts may never result in revenue. Capitalized Contract Costs As of December 31, 2021 and June 30, 2021, the balance of capitalized costs to obtain a contract was $ 10.3 million and $ 8.9 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 incurred impairment losses of $ 0.2 million and $ 0.3 million, respectively, in the three and six month periods ended December 31, 2021 and $ 0.2 million and $ 0.3 million, respectively, in the three and six month periods ended December 31, 2020, respectively. During the three and six months period ended December 31, 2021, the Company recognized $ 0.9 million and $ 1.8 million, respectively in expense related to the amortization of the capitalized contract costs. During the three and six months ended December 31, 2020, the Company recognized $ 0.6 million and $ 1.2 million, respectively, in expense related to the amortization of the capitalized contract costs.

Supplemental Financial Information Disclosure [Abstract]
Supplemental Financial Information	Note 4. Supplemental Financial Information Balance Sheet Components 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 in the Company’s balance sheet. The Company’s financing receivables, consisting of its accounts receivable with contractual maturities of more than one year, totaled $ 2.9 million and $ 3.4 million at December 31, 2021 and June 30, 2021, respectively, and are included in Other Assets in the unaudited condensed consolidated balance sheet. 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 customers 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. 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 performed an assessment of the allowance for credit losses related to its financing receivables. Based upon such assessment, the allowance for credit losses related to such financing receivables was $ 0.9 million for the periods ended December 31, 2021 and June 30, 2021. A summary of the Company’s financing receivables is presented as follows (in thousands): December 31, June 30, Financing receivable $ 6,293 $ 7,102 Allowance for credit loss ( 943 ) ( 943 ) Total, net $ 5,350 $ 6,159 Reported as: Current $ 2,459 $ 2,772 Non-current 2,891 3,387 Total, net $ 5,350 $ 6,159 The Company added and wrote off no amount from the allowance for credit losses during the six months ended December 31, 2021.

Depreciation expense related to property and equipment for the three and six months ended December 31, 2020 was $ 1.6 million and $ 3.2 million, respectively. Accumulated Other Comprehensive Income The changes in accumulated other comprehensive income are excluded from earnings and reported as a component of stockholders’ equity. The foreign currency translation adjustment results from those subsidiaries not using the U.S. Dollar as their functional currency since the majority of their economic activities are primarily denominated in their applicable local currency. Accordingly, all assets and liabilities related to these operations are translated to the U.S. Dollar at the current exchange rates at the end of each period. Revenues and expenses are translated at average exchange rates in effect during the period. The components of accumulated other comprehensive income in the equity section of the Company’s condensed consolidated balance sheet are as follows (in thousands): December 31, June 30, Cumulative foreign currency translation adjustment $ 2,580 $ 2,457 Defined benefit pension obligation ( 364 ) ( 364 ) Accumulated other comprehensive income $ 2,216 $ 2,093

Some of the Company’s leases are non-cancelable operating lease agreements with various expiration dates through June 2026. 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.

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 include the Euro, Japanese Yen, Swiss Franc, and U.S. Dollar. 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.

Fair Value Disclosures [Abstract]
Fair Value Measurements	Note 8. 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 on a Nonrecurring Basis As of December 31, 2021, the Company had open currency forward contracts to purchase or sell foreign currencies with a stated, or notional, value of approximately $ 55.2 million. The fair value of the underlying currency based upon the December 31, 2021 exchange rate was approximately $ 55.2 million, which it considers to be a Level 1 fair value measurement. As of June 30, 2021, the Company had open currency forward contracts to purchase or sell foreign currencies with a stated, or notional, value of approximately $ 54.2 million. The fair value of the underlying currency based upon the June 30, 2021 exchange rate was approximately $ 54.2 million, which it considers to be a Level 1 fair value measurement. The Company’s debt is measured on a non-recurring basis using Level 2 inputs based upon observable inputs of the Company’s underlying stock price and the time value of the conversion option since an observable quoted price of the 3.75 % Convertible Notes (as defined below) is not readily available. The Revolving Credit Facility (as defined below) and the Term Loan (as defined below) are valued at market interest rates, 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. The following table summarizes the carrying value and estimated fair value of the Term Loan, the Revolving Credit Facility, the 3.75 % Convertible Notes due 2022 and the 3.75% Convertible Notes due 2022 (in thousands): December 31, June 30, Carrying Fair Carrying Fair 3.75 % Convertible Notes Due 2022 $ 2,851 $ 3,261 $ 2,712 $ 3,164 3.75 % Convertible Notes Due 2026 97,344 115,606 72,388 108,163 Term Loan Facility 76,838 76,838 78,697 78,697 Revolving Credit Facility 5,000 5,000 20,000 20,000 Total $ 182,033 $ 200,705 $ 173,797 $ 210,024

Commitments And Contingencies Disclosure [Abstract]
Commitments and Contingencies	Note 9. Commitments and Contingencies 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. To the extent there is a reasonable possibility that a loss exceeding amounts already recognized may be incurred and the amount of such additional loss would be material, we will either disclose the estimated additional loss or state that such an estimate cannot be made. Currently, management believes the Company does not have any probable and reasonably estimable material 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. Indemnities 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 December 31, 2021. 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 December 31, 2021. Guarantees As of December 31, 2021 and June 30, 2021, the Company had various bank guarantees totaling approximately $ 0.9 million and $ 1.2 million, respectively, related to bidding processes with customers. Royalty Agreement The Company recorded royalty costs of $ 0.5 million and $ 0.9 million for the three and six months ended December 31, 2021, respectively, and $ 0.5 million and $ 0.9 million for the three and six months ended December 31, 2020, respectively, which were recorded in cost of revenue or deferred cost of revenue. The Company had approximately $ 2.4 million and $ 2.3 million accrued liabilities at December 31, 2021 and June 30, 2021, respectively, related to royalty agreements.

Debt 3.75% Convertible Senior Notes due July 2022 In August 2017, the Company issued $ 85.0 million aggregate principal amount of its 3.75 % Convertible Senior Notes due 2022 (the “ 3.75 % Convertible Notes due 2022”) under an indenture between the Company and The Bank of New York Mellon Trust Company, N.A., as trustee. $ 53.0 million aggregate principal amount of the 3.75 % Convertible Notes due 2022 were issued to certain holders of the Company’s then outstanding 3.50 % Convertible Notes due 2018 and 3.50 % Series A Convertible Notes due 2018 (together, the “Prior Existing Notes”) in exchange for approximately $ 47.0 million aggregate principal amount of the Prior Existing Notes and $ 32.0 million aggregate principal amount of the 3.75 % Convertible Notes due 2022 were issued to certain other qualified new investors for cash. The net proceeds of the cash issuance were used to repurchase approximately $ 28.0 million of Prior Existing Notes. Holders of the 3.75 % Convertible Notes due 2022 may convert their notes at any time on or after April 15, 2022 until the close of the business day immediately preceding the maturity date. Prior to April 15, 2022, holders of the 3.75 % Convertible Notes due 2022 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 174.8252 shares of the Company’s common stock per $ 1,000 principal amount (which represents an initial conversion price of approximately $ 5.72 per share of the Company’s common stock). The conversion rate, and thus the conversion price, is subject to adjustment as further described below. Holders of the 3.75 % Convertible Notes due 2022 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 2022 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 2022, plus accrued and unpaid interest, if any, to, but not including, the fundamental change repurchase date. In May 2021, the Company exchanged approximately $ 82.1 million aggregate principal amount of 3.75 % Convertible Notes due 2022 for approximately $ 97.1 million aggregate principal amount of 3.75 % Convertible Notes due 2026 (as defined below). As of June 30, 2021, $ 2.9 million aggregate principal amount of 3.75 % Convertible Notes due 2022 was outstanding. The exchange was treated as extinguishment of debt. The Company recorded a loss on the extinguishment of debt of $ 4.3 million, primarily comprised of the write-off of deferred costs associated with the 3.75 % Convertible Note due 2022 and the extinguishment of the equity component of $ 14.5 million recognized as reduction to additional paid in capital. The $ 14.5 million, which is the difference between the settlement consideration paid of $ 96.0 million and the fair value of the liability component of $ 81.5 million, represents the estimated fair value of the liability component based on the expected future cash flows associated with the aggregate principal amount of $ 82.1 million in 3.75 % Convertible Notes due 2022. 3.75% Convertible Senior Notes due July 2026 In May 2021, the Company issued $ 100.0 million aggregate principal amount of its 3.75 % Convertible Senior Notes due 2026 (the “ 3.75 % Convertible Notes due 2026”) under an indenture between the Company and The Bank of New York Mellon Trust Company, N.A., as trustee. $ 97.1 million aggregate principal amount of the 3.75 % Convertible Notes due 2026 were 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 thus 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, 2021, $ 100.0 million aggregate principal amount of 3.75 % Convertible Notes due 2026 was outstanding. The aggregate principal amount of $ 100.0 million, including $ 2.9 million which were issued to new qualified investors for cash in the 3.75 % Convertible Notes due 2026, was allocated between liability component of $ 74.1 million and equity component of $ 25.9 million recognized as addition paid in capital, reduced by $ 0.7 million of 3.75 % Convertible Notes due 2026 issuance cost allocated to additional paid in capital. Upon adoption of ASU No. 2020-06 on July 1, 2021, the Company recorded an increase to Accumulated deficit of $ 0.8 million, a decrease to Additional paid-in capital of $ 25.6 million, an increase to Debt, current of $ 24.8 million. There was no impact to diluted loss per share as the inclusion of potential shares of common stock related to the 3.75 % Convertible Notes due 2026 would have been anti-dilutive. The Company reversed the separation of the debt and equity components and accounted for the 3.75 % Convertible Notes due 2026 wholly as debt. The Company also reversed the amortization of the debt discount, with a cumulative adjustment to retained earnings on the adoption date. Debt issuance costs related to the 3.75 % Convertible Notes due 2022 and the 3.75 % Convertible Notes due 2026 were comprised of discounts, issuance costs and third party costs of $ 25.6 million. Prior to the adoption of ASU No. 2020-06, the Company allocated the total amount incurred to the liability and equity components of the 3.75 % Convertible Notes due 2022 and the 3.75 % Convertible Notes due 2026 based on their relative values. Issuance costs attributable to the liability component were $ 0.8 million and were amortized to interest expense using the effective interest method. Issuance costs attributable to the equity component were netted with the equity component in stockholders’ equity. Upon adoption of ASU No. 2020-06 on July 1, 2021, the Company reversed the allocation of the issuance costs to the equity component and accounted for the entire amount as debt issuance cost that will be amortized as interest expense for each of the respective terms of the 3.75% Convertible Notes due 2022 and the 3.75% Convertible Notes due 2026, respectively, with a cumulative adjustment to retained earnings on the adoption date. As of December 31, 2021, the if-converted value of the 3.75% Convertible Notes due 2022 and the 3.75% Convertible Notes due 2026 did not exceed the outstanding principal amount. 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 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”). The initial borrowings under the Credit Agreement, including $ 25 million under the Revolving Credit Facility, were funded on May 14, 2021. 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 LIBOR (subject to a 0.50 % floor) plus, initially, 3.00 % and after the Agent receives copies of the consolidated financial statements of the Company for the fiscal quarter ending June 30, 2021: 3.25 % if the Consolidated Senior Net Leverage Ratio (as defined in the Credit Agreement) is greater than or equal to 3.00:1.00; 3.00 % if the Consolidated Senior Net Leverage Ratio is greater than or equal to 2.00:1.00 but less than 3.00:1.00; 2.75 % if the Consolidated Senior Net Leverage Ratio is greater than or equal to 1.00:1.00 but less than 2.00:1.00; and 2.50 % if the Consolidated Senior Net Leverage Ratio is less than 1.00:1.00. The Credit Agreement requires the Company to pay the Lenders an unused commitment fee equal to, initially, 0.35 % per annum of the average unused portion of the Revolving Credit Facility and after the Agent receives copies of the consolidated financial statements of the Company for the fiscal quarter ending June 30, 2021: 0.40 % per annum of the average unused portion of the Revolving Credit Facility if the Consolidated Senior Net Leverage Ratio is greater than or equal to 3.00:1.00; 0.35 % per annum of the average unused portion of the Revolving Credit Facility if the Consolidated Senior Net Leverage Ratio is greater than or equal to 2.00:1.00 but less than 3.00:1.00; 0.30 % per annum of the average unused portion of the Revolving Credit Facility if the Consolidated Senior Net Leverage Ratio is greater than or equal to 1.00:1.00 but less than 2.00:1.00; and 0.25 % per annum of the average unused portion of the Revolving Credit Facility if the Consolidated Senior Net Leverage Ratio is less than 1.00:1.00. 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 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. 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.

Segment Reporting [Abstract]
Segment Information	Note 13. Segment Information 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 area. 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. Additionally, the Company typically recognizes revenue at a point in time for product revenue and recognizes revenue over time for service revenue. Revenues attributed to a country or region is based on the shipping addresses of the Company’s customers.

Equity Method Investments And Joint Ventures [Abstract]
Joint Venture	Note 14. 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. In exchange for a 49 % equity interest in the JV, the Company, through Accuray Asia, made in-kind capital contributions of two full radiation oncology systems in the quarter ended December 31, 2019 and one system upgrade in the quarter ended September 30, 2020, all of which was not to be sold and only be used for training purposes by the JV. The investments are 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 revenue on sales to the JV in the current period, eliminating a portion of profit to the extent goods sold have not been sold through by the JV to an end customer at the end of such reporting period. The Company deferred $ 3.1 million and $ 2.1 million of intra-entity profit margin as of December 31, 2021 and June 30, 2021, respectively. During the three months ended December 31, 2021, the Company recognized $ 1.0 million of previously deferred intra-entity profit margin from sales and recorded intra-entity profit margin deferral of $ 0.2 million from sales executed during the period. During the six months ended December 31, 2021, the Company recognized $ 1.2 million of previously deferred intra-entity profit margin from sales and recorded intra-entity profit margin deferral of $ 2.2 million from sales executed during the period. During the three months ended December 31, 2020, the Company recognized $ 0.6 million of previously deferred intra-entity profit margin from sales and recorded intra-entity profit margin deferral of $ 0.3 million from sales executed during the period. During the six months ended December 31, 2020, the Company recognized $ 1.5 million of previously deferred intra-entity profit margin from sales and recorded intra-entity profit margin deferral of $ 0.9 million from system sales executed during the period. The Company’s consolidated accumulated deficit includes $ 0.5 million of accumulated losses related to the Company’s equity method investment. As of December 31, 2021, the Company had carrying value of $ 14.7 million in the JV and owned a 49 % interest in the entity. The Company’s proportional share of the underlying equity in net assets of the JV was approximately $ 13.1 million. Under the equity method of accounting, the carrying value of the investment is adjusted for the Company's proportional share of the investee's currency translation adjustment of $ 0.9 million. The difference between the carrying value of the equity investment and the Company’s proportional share of the underlying equity in net assets of the JV of $ 1.6 million, adding back a $ 3.1 million of eliminated intra-entity profit constitutes equity method goodwill of $ 4.7 million at December 31, 2021 that is subject to impairment analysis. No impairment was identified as of December 31, 2021. Summarized financial information of the JV is based one-quarter lag due to the timing of the availability of the JV’s financial records is as follows (in thousands): Six Months Ended September 30, 2021 Six Months Ended September 30, 2020 Statement of Operations Data: Revenue $ 15,792 $ 17,374 Gross Profit 4,942 5,449 Net income (loss) ( 2,391 ) 2,228 Net income (loss) attributable to the Company ( 1,172 ) 1,089 As of As of Summarized Balance Sheet Data: Assets Current assets $ 59,250 $ 22,480 Non current assets 22,677 19,476 $ 81,927 $ 41,956 Liabilities and Stockholders' Equity Current liabilities $ 53,700 $ 12,334 Non current liabilities 1,147 1,260 Stockholder's equity 27,080 28,362 $ 81,927 $ 41,956

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 is expected to be fully absorbed by net operating losses carryforward and is not expected to cause the Company to be in a U.S. taxable income position for fiscal year 2022. As of December 31, 2021, the Company’s gross unrecognized tax benefits was $ 18.8 million of which $ 18.6 million would not affect income tax expense before consideration of any valuation allowance.

Organization Consolidation And Presentation Of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation The unaudited condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All significant inter-company transactions and balances have been eliminated in consolidation. The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with United States generally accepted accounting principles (“GAAP”), pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”). Certain information and note disclosures have been condensed or omitted pursuant to such rules and regulations. The unaudited condensed consolidated financial statements have been prepared on the same basis as the annual financial statements and, in the opinion of management, reflect all adjustments, which include only normal recurring adjustments, necessary for a fair presentation of the periods presented. The results for the three and six months ended December 31, 2021 are not necessarily indicative of the results to be expected for the fiscal year ending June 30, 2022, or for any other future interim period or fiscal year. These unaudited condensed consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements and accompanying notes for the fiscal year ended June 30, 2021 included in the Company’s Annual Report on Form 10-K filed with the SEC on August 17, 2021.
Risks and Uncertainties	Risks and Uncertainties The Company is subject to risks and uncertainties as a result of a novel strain of coronavirus, severe acute respiratory syndrome coronavirus 2, or SARS-CoV-2, which causes coronavirus disease 2019 (“COVID-19”) and has resulted in a worldwide pandemic. The extent of the impact of the COVID-19 pandemic on the Company's business is highly uncertain and difficult to predict, as the effects of and response to the pandemic are rapidly evolving and new information is regularly coming to light, particularly as new COVID-19 variants emerge. The Company's customers are diverting resources to treat COVID-19 patients and deferring non-urgent and elective procedures. Some customers, which include hospitals, major academic medical centers, and other related entities, have incurred significant losses during the COVID-19 pandemic due to reduced patient volume. These impacts on our customers may adversely affect their ability to meet their financial and other contractual obligations, including to the Company. Furthermore, global economic uncertainty, including labor shortages, related to the COVID-19 pandemic may result in an incremental adverse impact on revenue, net income (loss) and cash flow and may require significant additional expenditures or cost-cutting to mitigate such impacts. Policymakers around the globe have responded with fiscal policy actions to support the healthcare industry and economy as a whole. The magnitude and overall effectiveness of these actions remain uncertain. The Company’s financial results have also been affected by the COVID-19 pandemic in various ways. The COVID-19 pandemic is adversely impacting the pace at which the Company’s backlog converts to revenue. This is primarily the result of pandemic-related delays in the timing of deliveries and installations, which has adversely affected our revenue. The Company has experienced such delays in deliveries and installations since the third quarter of fiscal year 2020 and expects that such delays in will continue at least through the end of fiscal 2022 if not longer, which could have a negative impact on revenue. The Company has experienced disruptions in its sales cycle as well as delays in customer payments and service agreements. The Company also received requests from a few customers to extend payment terms or temporarily suspend service and corresponding payment obligations. While the Company has only received a small number of requests thus far, there can be no guarantee that more customers will not ask for the same in the future. In addition, as the COVID-19 pandemic continues to impact the global supply chain, disruptions in parts of our supply chain have resulted in delays in the receipt of certain components for our products as well as increased pricing pressure for such parts. These ongoing supply chain challenges and heightened logistics costs have adversely affected our gross margins and net income (loss), and the Company’s current expectations are that gross margins and net income (loss) will continue to be adversely affected by increased material costs and freight and logistic expenses through at least the remainder of the fiscal year 2022, if not longer. Furthermore, certain parts required for the manufacture and servicing of our products, such as electronic components, are scarce and becoming increasingly difficult to source even at increased prices. If such parts become unavailable to us, we would not be able to manufacture or service our products, which would adversely impact revenue, gross margins, and net income (loss). As a result, the Company is carefully monitoring the pandemic and the potential length and depth of the resulting economic impact on our financial condition and results of operations. There remain uncertainties around the spread, severity and potential resurgence of COVID-19, the impact of new COVID-19 variants, vaccination deployment efforts, and how long the pandemic and associated health measures will last, the related financial impact cannot be reasonably estimated at this time, although the impacts are expected to continue and may significantly affect the Company’s business. The Company continues to critically review its liquidity and anticipated capital requirements in light of the significant uncertainty created by the COVID-19 pandemic. 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. However, the Company is unable to predict with certainty the impact of the COVID-19 pandemic, 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 10 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 December 31, 2021. 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 and the unknown future impacts of the COVID-19 pandemic. Key estimates and assumptions made by the Company relate to revenue recognition and the assessment of stand-alone selling price (“SSP”), assessment of recoverability of goodwill and intangible assets, valuation of our equity method investment in the JV, valuation of inventories, annual performance related bonuses, allowance for credit losses and loss contingencies. Actual results could differ materially from those estimates.
Significant Accounting Policies	Significant Accounting Policies Other than the policy adoption discussed below under Accounting Pronouncements Recently Adopted, there have been no changes in the Company’s significant accounting policies during the six months ended December 31, 2021 compared to the significant accounting policies described in its Annual Report on Form 10-K for the fiscal year ended June 30, 2021 .

Accounting Pronouncement Recently Adopted
Accounting Pronouncements	Accounting Pronouncement Recently Adopted In December 2019, the FASB issued ASU No. 2019-12, Income Taxes (Topic 740): Simplifying Accounting for Income Taxes (“ASU 2019-12”). The amendments in ASU 2019-12 are intended to simplify various aspects related to accounting for income taxes and reduce the cost of accounting for income taxes. ASU 2019-12 removes certain exceptions to the general principles in Topic 740 and also clarifies and amends existing guidance to improve consistent application. The Company adopted ASU 2019-12 on July 1, 2021. The adoption of this standard did not have a material impact on its consolidated financial statements. In January 2020, the FASB issued ASU 2020-01 Investments-Equity Securities (Topic 321), Investments-Equity Method and Joint Ventures (Topic 323), and Derivatives and Hedging (Topic 815) - Clarifying the Interactions between Topic 321, Topic 323, and Topic 815. This guidance addresses accounting for the transition into and out of the equity method and provides clarification of the interaction of rules for equity securities, the equity method of accounting, and forward contracts and purchase options on certain types of securities. This standard is effective for fiscal years and interim periods within those fiscal years beginning after December 15, 2020. The Company adopted ASU 2020-01 on July 1, 2021. The adoption of this standard did not have a material impact on its consolidated financial statements. In August 2020, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update (“ASU”) No. 2020-06 , Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging—Contracts in Entity’s Own Equity (Subtopic 815-40). Under ASU No. 2020-06, the embedded conversion features are no longer separated from the host contract for convertible instruments with conversion features that are not required to be accounted for as derivatives under Topic 815, or that do not result in substantial premiums accounted for as paid-in capital. Consequently, a convertible debt instrument will be accounted for as a single liability measured at its amortized cost, as long as no other features require bifurcation and recognition as derivatives. The new guidance also requires the if-converted method to be applied for all convertible instruments when calculating diluted earnings per share. The Company adopted this standard effective July 1, 2021, using a modified retrospective method, under which financial results reported in prior periods were not adjusted. The Company applied the provisions of this guidance to our 3.75 % convertible senior notes due June 2026 (“2026 Notes”). Upon adoption, the Company recorded an increase to Accumulated deficit of $ 0.8 million, a decrease to Additional paid-in capital of $ 25.6 million and an increase to Debt of $ 24.8 million. There was no impact to diluted loss per share as the inclusion of potential shares of common stock related to the 2026 Notes would have been anti-dilutive. For further information, see Note 10, Debt. In October 2020, the FASB issued ASU 2020-10, Codification Improvements - Disclosures. This ASU improves consistency by amending the codification to include all disclosure guidance in the appropriate disclosure sections and clarifies application of various provisions in the codification by amending and adding new headings, cross referencing to other guidance, and refining or correcting terminology. This ASU is effective for fiscal years beginning after December 15, 2020. This ASU will not affect the Company's results of operations, cash flows or financial position. The adoption of ASU No. 2020-10 by the Company effective July 1, 2021 did not have a material impact on the Company’s financial statements or disclosures.
Accounting Pronouncements Not Yet Effective
Accounting Pronouncements	Accounting Pronouncements Not Yet Effective 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. The guidance in ASU 2020-04 is optional and may be elected over time as reference rate reform activities occur. The Company’s Term Loan Facility and Revolving Credit Facility applies Eurodollar rate LIBOR to the variable component of the interest rate, if a Benchmark transition event, or an early opt-in election, as applicable occurred a transition to the use of the Secured Overnight Financing Rate ("SOFR") to replace such rate. The Company is currently evaluating the impact of the guidance and our options related to the practical expedients. In October 2021, the FASB issued ASU No. 2021-08, Accounting for Contract Assets and Contract Liabilities from Contracts with Customers. The amendment addresses how to account for contract assets recognized under Topic 606 in a business combination. This standard is effective for fiscal years and interim periods within those fiscal years beginning after December 15, 2022. The Company is currently evaluating the impact ASU 2021-08 will have on its financial statements.
