Notes to Unaudited Condensed Consolidated Financial Statements

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 months ended September 30, 2018 are not necessarily indicative of the results to be expected for the fiscal year ending June 30, 2019, 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, 2018 included in the Company’s Annual Report on Form 10-K filed with the SEC on August 24, 2018.

Significant Accounting Policies

The Company adopted the Accounting Standard Codification (“ASC”) 606, Revenue from Contracts with Customers as of July 1, 2018, using the modified retrospective method. See Note 2. Recent Accounting Pronouncements and Note 3. Revenue, to our unaudited condensed consolidated financial statements included in this Quarterly Report on Form 10-Q for additional details. Except for the changes in the revenue recognition policy, there have been no other material changes to the Company’s accounting policies from the information provided in Note 1. The Company and its Significant Accounting Policies to the audited consolidated financial statements included in the Company’s Annual Report on Form 10-K for the year ended June 30, 2018.

Revenue Recognition

The Company’s revenue is primarily derived from sales of CyberKnife and TomoTherapy Systems and services, which include post-contract customer support (“PCS”), installation services, training and other professional services.

The Company has a contract with a customer when there is approval and commitment from both parties, the rights of the parties are identified, payment terms are identified, the contract has commercial substance and collectability of consideration is probable.

The Company’s customary practice is to have a signed contract with customers. The Company's revenues are measured based on consideration specified in the contract with each customer, net of any sales incentives and amounts collected on behalf of third parties such as sales taxes, excise taxes, and VAT.

The majority of the Company's revenue arrangements consists 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.  

6

The Company’s products are generally not sold with a right of return, and the Company’s contracts generally provide a fixed transaction price. However, the Company from time to time offers variable consideration such as volume discounts. The Company also offers extended payment terms beyond one year, trade-in allowance for old systems, and commissions or other forms of payment to customers.

The stand-alone selling price (“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 will estimate the SSP considering market conditions, entity-specific factors, and information about the customer or class of customer that is reasonably available. The SSP is generally assessed as a percentage of the list price. 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 individual SSP. For contract modifications that add additional goods or services or changes pricing, the SSP is used for allocation to the remaining performance obligations.

The Company recognizes revenue for certain performance obligations at the point in time when control is transferred, such as delivery of products. The Company recognizes revenue for certain other performance obligations over a period of time as control of the goods or services is transferred, such as PCS and construction contracts.  

The Company recognizes an asset for the incremental costs of obtaining a contract with a customer if the Company expects the benefit of those costs to be longer than one year. The Company capitalizes incremental contract acquisition costs, and amortizes such costs over the period which the Company expects to benefit, as estimated by management, which may extend beyond the initial contract term. 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 amortizes capitalized bonuses and a portion of sales commissions 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 Company elected to use the practical expedient in ASC 340-40-25-4 and expense as incurred commissions related to service renewals and upgrades because the contract term is less than a year.

Note 2. Recent Accounting Pronouncements

Accounting Pronouncement Recently Adopted

In June 2018, the Financial Accounting Standard Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2018-7, Compensation – Stock Compensation (Topic 718) )— Improvements to Nonemployee Share-Based Payment Accounting. This guidance supersedes ASC 505-50 and expands the scope of ASC 718 to include all share-based payment arrangements related to the acquisition of goods and services from both nonemployees and employees. The amendments should be applied on a modified retrospective basis through a cumulative-effect adjustment to retained earnings as of the beginning of the fiscal year of adoption. The guidance permits early adoption and was adopted by the Company in the first quarter of fiscal year 2019. The adoption of this ASU did not have any impact on the Company’s consolidated financial statements and related disclosures.

In May 2017, the FASB issued ASU No. 2017-09, Compensation—Stock Compensation (Topic 718)—Scope of Modification Accounting. This guidance redefines which changes to the terms and conditions of a share-based payment award require an entity to apply modification accounting for a share-based payment. Modification accounting will not be applied if the following are the same immediately before and after the change: fair value, vesting conditions, and classification. The Company adopted ASU No. 2017-09 as required in the first quarter of fiscal 2019 on a prospective basis. The adoption of this ASU did not have any impact on the Company’s consolidated financial statements and related disclosures.

In March 2017, the FASB issued ASU No. 2017-07, Compensation—Retirement Benefits (Topic 715)—Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost. This guidance revises the presentation of employer-sponsored defined benefit pension and other postretirement plans for the net periodic benefit cost in the statement of operations and requires that the service cost component of net periodic benefit be presented in the same income statement line items as other employee compensation costs for services rendered during the period. The other components of the net benefit costs are required to be presented in the statement of operations separately from the service cost component and outside the subtotal of income from operations. This guidance allows only the service cost component of net periodic benefit costs to be eligible for capitalization. In addition, changes to the presentation of benefit costs were required to be adopted retrospectively, while changes to the capitalization of service costs into inventories were required to be adopted prospectively. The standard permits, as a practical expedient, use of the amounts disclosed in the pension plans footnote for the prior comparative periods as the estimation basis for applying the retrospective presentation requirement. The Company adopted ASU No. 2017-07 as required in the first quarter of fiscal 2019, and the adoption of this ASU did not have a material impact on the Company’s consolidated financial statements and related disclosures.

7

In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments, which clarifies the presentation and classification of certain cash receipts and cash payments in the statement of cash flows. The amendments in the update provide guidance on eight specific cash flow issues. The amendments to the guidance should be applied using a retrospective transition method for each period presented and, if it is impracticable to apply all of the amendments retrospectively for some of the issues, the amendments for those issues would be applied prospectively as of the earliest date practicable. The Company adopted ASU No. 2016-15 as required in the first quarter of fiscal 2019. The adoption of this ASU did not have any impact on the Company’s consolidated financial statements and related disclosures.

In January 2016, the FASB issued ASU No. 2016-01, Recognition and Measurement of Financial Assets and Financial Liabilities (ASU 2016-01). This guidance changes accounting for equity investments, financial liabilities under the fair value option and the presentation and disclosure requirements for financial instruments. In addition, it clarified guidance related to the valuation allowance assessment when recognizing deferred tax assets resulting from unrealized losses on available-for-sale debt securities. The Company adopted this ASU No. 2016-01 as required in the first quarter of fiscal 2019 on a required modified retrospective approach. The adoption of this ASU did not have any impact on the Company’s consolidated financial statements and related disclosures.

In January 2017, the FASB issued ASU No. 2017-04, Intangibles-Goodwill and Other Topics (Topic 350)-Simplifying the Test for Goodwill Impairment. This guidance simplifies the measurement of goodwill by eliminating the Step 2 impairment test. The new guidance requires companies to perform the goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. This guidance will be effective for the Company beginning in its first quarter of fiscal 2021. The amendment is required to be adopted prospectively. Early adoption is permitted for goodwill impairment tests performed on testing dates after January 1, 2017. The Company early adopted this guidance in the first quarter of fiscal 2019 and adoption of this ASU did not have any impact on its consolidated financial statements and related disclosures.

In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606), to supersede nearly all existing revenue recognition guidance under GAAP. The core principle of ASU 2014-09 is to recognize revenue when promised goods or services are transferred to customers in an amount that reflects the consideration that is expected to be received for those goods or services. ASU 2014-09 defines a five-step process to achieve this core principle and, in doing so, it is possible more judgment and estimates may be required within the revenue recognition process than required under existing GAAP, including identifying performance obligations in the contract, estimating the amount of variable consideration to include in the transaction price and allocating the transaction price to each separate performance obligation. ASU 2014-09 is required to be adopted, using either of two methods: (i) retrospective to each prior reporting period presented with the option to elect certain practical expedients as defined within ASU 2014-09; or (ii) retrospective with the cumulative effect of initially applying ASU 2014-09 recognized at the date of initial application and providing certain additional disclosures. The Company adopted the new revenue standards as of July 1, 2018, using the modified retrospective transition method applied to those contracts which were not completed as of that date.

The Company completed its assessment of the impact this guidance has on its consolidated financial statements and related disclosures. Based on that assessment, the Company concluded the significant impact areas were the capitalization and amortization of incremental costs of obtaining a contract, primarily related to certain bonuses and sales commissions, change in SSP and the removal of software revenue recognition rules along with the elimination of revenue deferral for cash basis customers. Under the new standards, the Company capitalizes incremental contract acquisition costs, such as certain bonuses and sales commissions, and amortizes such costs over the period which the Company benefits, as estimated by management, which may extend beyond the initial contract term. The Company amortizes capitalized bonuses and sales commissions 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 Company elected to use the practical expedient in ASC 340-40-25-4 and expense commissions related to service renewals and upgrades with a renewal contract term of one year or less as incurred. The Company recorded a net reduction to opening accumulated deficit  of $5.1 million, net of tax, as of July 1, 2018 due to the cumulative impact of adopting ASC 606, with the impact primarily related to the deferral of incremental costs to obtain contracts.

Under ASC 606, product revenue for direct sales will be accelerated to reflect transfer of control upon delivery while an element of installation will be deferred until performed. Prior to the adoption of ASC 606, the Company deferred revenue until installation had occurred. The revenue recognition method for indirect sales and service revenues is unchanged under the new guidance.

Refer to Note 3, Revenue, to the Unaudited Condensed Consolidated Financial Statement on this Quarterly report for the detailed impact of adopting ASC 606.

Accounting Pronouncements Not Yet Effective

In February 2018, the FASB issued ASU No. 2018-2, Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income, that allows companies to reclassify from Accumulated Other Comprehensive Income to Retained Earnings stranded tax effects resulting from the enactment of the Tax Cuts and Jobs Act (the "Tax Act"). The guidance will be effective for the Company in its first quarter of fiscal 2020. Early adoption is permitted. The guidance should be applied either in the period of adoption or retrospectively to each period in which the effect of the change in the U.S. federal corporate income tax rate in the Tax Cuts and Jobs Act is recognized. The Company has not yet selected a transition method, has not yet determined whether it will elect early adoption and is currently evaluating the impact of the adoption of this standard on its consolidated financial statements and related disclosures.

In August 2017, the FASB issued ASU No. 2017-12, Derivatives and Hedging. This guidance simplifies the application and administration of hedge accounting. The guidance amends the presentation and disclosure requirements and changes how companies assess effectiveness. The guidance is intended to more closely align hedge accounting with companies' risk management strategies, simplify the application of hedge accounting, and increase transparency as to the scope and results of hedging programs. The guidance will be effective for the Company in its first quarter of fiscal 2020. Early adoption is permitted. The guidance is required to be adopted on a prospective basis. The Company will not early adopt and does not believe the adoption of this standard will have a material impact on its consolidated financial statements and related disclosures.

In June 2016, the FASB issued ASU No. 2016-13 Measurement of Credit Losses on Financial Instruments (ASU 2016-13). ASU 2016-13 requires measurement and recognition of expected credit losses for financial assets held. This guidance will be effective for the Company in the first quarter of fiscal 2021 and must be adopted using a modified retrospective approach, with certain exceptions. Early adoption is permitted beginning in the first quarter of fiscal 2020. The Company has not yet decided whether it will early adopt and is currently evaluating the impact of the adoption of this standard on its consolidated financial statements and related disclosures.

In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842). Under the new guidance, a lessee will be required to recognize assets and liabilities for all leases with lease terms of more than 12 months. Consistent with current GAAP, the recognition, measurement, and presentation of expenses and cash flows arising from a lease by a lessee primarily will depend on its classification as a finance or operating lease. This guidance will be effective for the Company in the first quarter of fiscal 2020 and early adoption is permitted. In July 2018, the FASB issued ASU No. 2018-11, Targeted Improvements, which provides another transition method in addition to the existing modified retrospective transition approach. Accordingly, the new method allows entities to initially apply the new leases standard at the adoption date and recognize a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption. The Company intends to adopt the  allowed transition method allowed under ASU 2018-11, but will not elect early adoption, and is currently evaluating the impact of the adoption of this standard on its consolidated financial statements and related disclosures.

Note 3. Revenue

On July 1, 2018 the Company adopted ASC 606 electing the modified retrospective method for contracts that were still open as of July 1, 2018. Results for reporting periods after July 1, 2018 are presented under ASC 606, while prior period amounts are not adjusted and continue to be reported in accordance with legacy accounting guidance under ASC 605.

The beginning net cumulative-effect adjustment to retained earnings for the adoption of ASC 606 is as follows:

Contract Balances

The timing of revenue recognition, billings, and cash collections results in trade, unbilled receivables, and deferred revenues on the unaudited condensed consolidated statement of 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 deferred revenues, which represents 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:

Changes in deferred revenue from contracts with customers are as follows:

Remaining Performance Obligations

Remaining performance obligations represent deferred revenue from open contracts for which performance has already started and the transaction price from signed contracts for which performance has not yet started. Service contracts in general are considered month-to-month contracts, and therefore, the Company has elected the practical expedients available in the guidance related to ASC 606, to not disclose the value of unsatisfied performance obligations for contracts with an original expected duration of one year or less.

As of September 30, 2018, total remaining performance obligations amounted to $731.0 million. Of this total amount, $66.5 million related to long-term warranty and service, which is expected to be recognized over the remaining warranty period for systems that have been delivered. For system that have been delivered but not yet installed, management estimates the timing of installation since warranty starts upon installation.

      The following table represents the Company's remaining performance obligations related to long-term warranty and service as of September 30, 2018 and the estimated revenue expected to be recognized:

11

      For the remaining $664.5 million of performance obligations, the Company estimates 30% to 40% will be recognized in the next 12 months, and the remaining 60% to 70% will be recognized in the 30 months 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. As such, about 15% to 20% of the Company’s contracts may never result in revenue due to cancellation.

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.

Capitalized Contract Costs

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 opening balance of capitalized costs to obtain a contract was $5.9 million as of July 1, 2018. As of September 30, 2018, the balance of capitalized costs to obtain a contract was $6.2 million. 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 did not incur any impairment losses during any of the periods presented. During the three months ended September 30, 2018, the Company recognized $0.9 million in expense related to the amortization of the capitalized contract costs.

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 on the Company’s balance sheet. The Company’s financing receivables, consisting of its accounts receivable with contractual maturities of more than one year and sales-type leases, totaled $4.2 million and $6.9 million at September 30, 2018 and June 30, 2018, respectively, and are included in other assets in the unaudited condensed consolidated balance sheets. The Company evaluates the credit quality of an obligor at lease or 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 transaction. Such variables include the underlying value and liquidity of the collateral, the essential use of the equipment, the term of the lease 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. As of September 30, 2018, the sales-type lease portion of the financing receivables was rated at a moderate risk. The Company performed an assessment of the allowance for credit losses related to its financing receivables as of September 30, 2018 and June 30, 2018. Based upon such assessment, the Company recorded $3.3 million and zero adjustment to the allowance for credit losses related to such financing receivables as of September 30, 2018 and as of June 30, 2018, respectively.

A summary of the Company’s financing receivables is presented as follows (in thousands):

12

Actual cash collections may differ from the contracted maturities due to early customer buyouts, refinancing, or defaults. Future minimum lease payments to be received as of September 30, 2018 are presented as follows (in thousands):

Inventories

Inventories consisted of the following (in thousands):

Property and equipment, net

Property and equipment, net consisted of the following (in thousands):

Depreciation expense related to property and equipment for the three months ended September 30, 2018 and 2017 was $2.1 million and $2.5 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

13

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 balance sheets are as follows (in thousands):

Note 5. Goodwill and Intangible Assets

Goodwill

Activity related to goodwill consisted of the following (in thousands):

In the second quarter of fiscal 2018, the Company performed its annual goodwill impairment test. Based on this analysis, the Company determined that there was no impairment to goodwill. The Company will continue to monitor its recorded goodwill for indicators of impairment.

Intangible Assets

The Company’s carrying amount of acquired intangible assets, net, is as follows (in thousands):

The Company did not identify any triggering events that would indicate potential impairment of its definite-lived intangible and long-lived assets as of September 30, 2018 and June 30, 2018.

Amortization expense related to intangible assets for the three months ended September 30, 2018 and 2017 was each $0.04 million.

The estimated future amortization expense of acquired intangible assets as of September 30, 2018 is as follows (in thousands):

14

Note 6. Investments

The Company considers all highly liquid investments held at major banks, certificates of deposit and other securities with original maturities of three months or less to be cash equivalents.

The Company classifies all of its investments as available-for-sale at the time of purchase because management intends that these investments are available for current operations and includes these investments on its balance sheet as short-term investments. Investments with original maturities longer than three months include commercial paper, U.S. agency securities, non-U.S. government securities and investment-grade corporate debt securities. Investments classified as available-for-sale are recorded at fair market value with the related unrealized gains and losses included in accumulated other comprehensive income, a component of stockholders’ equity. Realized gains and losses are recorded based on specific identification of each security’s cost basis.

The Company sold all of its investments in fiscal 2018 and as such, no investments were outstanding as of September 30, 2018 and June 30, 2018.  

Note 7. Derivative Financial Instruments

The Company manages some of its foreign currency risk through the purchase of foreign currency forward contracts that hedge against the short-term effect of currency fluctuations. These foreign currency forward contracts have a monthly maturity that mitigates the effect of rate fluctuations on certain local currency denominated intercompany balances, cash, and customer receivables. 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. There were no outstanding foreign currency forward contracts at the end of September 30, 2018 and June 30, 2018.

The following table provides information about gain (loss) associated with the Company’s derivative financial instruments (in thousands):

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:

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.

The Company does not carry any investments, and its cash balance was $68.5 million and $83.1 million at September 30, 2018 and June 30, 2018, respectively.

15

Liabilities That Are Measured at Fair Value on a Nonrecurring Basis

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) are not readily available. The Revolving Credit Facility (as defined below) and the Term Loan (as defined below) (collectively the “Credit Facilities”) are valued at market interest rates, which it considers to be a level 2 fair value measurement. The carrying value of these financial instruments approximate its estimated fair value as there have not been significant changes in the Company’s credit quality or capital markets that would suggest changes in interest rates since the Credit Facilities were issued or amended in December 2017.

The following table summarizes the carrying value and estimated fair value of the Credit Facilities and the 3.75% Convertible Notes (in thousands):

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. Currently, management believes the Company does not have any probable and estimable losses related to 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.

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 them. 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 September 30, 2018.

3.50% Convertible Senior Notes due February 2018

In February 2013, the Company issued 3.50% Convertible Senior Notes due 2018 (the “3.50% Convertible Notes”) under an indenture between the Company and The Bank of New York Mellon Trust Company, N.A., as trustee. Holders of the 3.50% Convertible Notes were entitled to convert their notes at any time until the close of the business day immediately preceding the maturity date of February 1, 2018. The 3.50% Convertible Notes were convertible into common stock of the Company at an initial conversion rate equal to 187.6877 shares of common stock per $1,000 principal amount, which is equivalent to a conversion price of approximately $5.33 per share of common stock, subject to adjustment.  

16

On January 30, 2018, the Company entered into exchange agreements (the “Exchange Agreements”) with the holders of the 3.50% Convertible Notes, which amended the original settlement terms of the notes and allowed the Company to settle the then outstanding $13.0 million principal balance of the 3.50% Convertible Notes and accrued interest in cash at maturity, and any excess equity value over the original conversion price in shares. In exchange for the agreement to settle in cash, the Company agreed to pay a $0.3 million exchange premium. The $0.3 million exchange premium was accounted for as debt extinguishment and included in other expense, net.

On February 1, 2018, pursuant to the Exchange Agreements, the Company paid $13.2 million in cash to settle outstanding principal and accrued interest, and on February 7, 2018 issued 253,000 shares of the Company’s common stock to the holders of the 3.50% Convertible Notes. The total number of shares was determined using a three-day volume weighted averaging price period and based on a prescribed formula in the Exchange Agreements. As a result, the 3.50% Convertible Notes were repaid in full in fiscal year 2018.

3.50% Series A Convertible Senior Notes due February 2018

In April 2014, the Company issued 3.50% Series A Convertible Senior Notes due 2018 (the “3.50% Series A Convertible Notes”) under an indenture between the Company and The Bank of New York Mellon Trust Company, N.A., as trustee. Holders of the 3.50% Series A Convertible Notes were entitled to convert their notes at any time on or after November 1, 2017 until the close of business on the business day immediately preceding the maturity date of February 1, 2018. The initial conversion rate is 187.6877 shares of the Company’s common stock per $1,000 principal amount, which represents an initial conversion price of approximately $5.33 per share of the Company’s common stock.

Pursuant to the original settlement terms, the Company made an irrevocable net share settlement election and paid cash for principal plus accrued interest upon maturity to holders who did not elect to convert. Prior to maturity, one note holder elected to convert its notes and receive a combination of cash and shares at settlement. The number of shares was determined based on a prescribed formula in the indenture. On February 1, 2018, the Company paid an aggregate amount of $27.0 million in cash and delivered 1,252 shares of its common stock to settle the 3.50% Series A Convertible Notes. As a result, the 3.50% Series A Convertible Notes were repaid in full in fiscal year 2018.

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”) 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 were issued to certain holders of the Company’s outstanding 3.50% Convertible Notes and 3.50% Series A Convertible Notes (together, the “Existing Notes”) in exchange for approximately $47.0 million aggregate principal amount of the Existing Notes (the “Exchange”), and $32.0 million aggregate principal amount of the 3.75% Convertible Notes 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 Existing Notes (the “Repurchase”).

Holders of the 3.75% Convertible Notes 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 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 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 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, plus accrued and unpaid interest, if any, to, but not including, the fundamental change repurchase date. As of September 30, 2018, $85.0 million of aggregate principal amount was outstanding.

Revolving Credit Facility

On June 14, 2017, the Company entered into a credit and security agreement with a lender (the “Credit Agreement”). The Credit Agreement provides the Company with a revolving credit facility in the initial amount of $52.0 million (the “Revolving Credit Facility”). Availability for borrowings under the Revolving Credit Facility is subject to a borrowing base that is calculated as a function of the value of the Company’s eligible accounts receivable and eligible inventory, and the Company is required to maintain a minimum

17

drawn balance of at least 30% of such availability. Interest on the borrowings under the Revolving Credit Facility is payable monthly in arrears at an annual interest rate of reserve-adjusted, 90-day LIBOR plus 4.50% and had an initial maturity date of June 14, 2021.

In December 2017, concurrently with the Term Loan Agreement described below, the Company entered into an amendment to the Credit Agreement (the “Amendment” and, collectively with the Credit Agreement, the “Amended Credit Agreement”). The Amendment reduced the maximum borrowings under the Revolving Credit Facility to $32.0 million and extended the maturity date of the Revolving Credit Facility to December 15, 2022.

The Amended Credit Agreement contains restrictions and covenants applicable to the Company. Among other requirements, the Company may not permit the Fixed Charge Coverage Ratio (as defined in the Amended Credit Agreement) to be less than a certain specified ratio for each fiscal quarter during the term of the Revolving Credit Facility. In addition, the Amended Credit Agreement contains customary restrictive covenants that limit, among other things, the ability of the Company and its subsidiaries to (i) incur additional 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.

In July 2018, the Company amended both the Amended Credit Agreement and the Term Loan Agreement (as defined below). The amendments provide for, among other things, adjustments to the Fixed Charge Coverage Ratio (as defined in the Amended Credit Agreement and the Term Loan Agreement) such that in the case of the Defined Periods (as defined in the Amended Credit Agreement and the Term Loan Agreement) for (a) the fiscal quarter ending June 30, 2018 as well as (b) the fiscal quarters ending September 30, 2018 and December 31, 2018, the Fixed Charge Coverage Ratio is not less than 0.75 to 1.00 and 0.50 to 1.00, respectively. Other significant terms remain unchanged.

The Company was in compliance with the covenants as of September 30, 2018. As of September 30, 2018, approximately $20.4 million of aggregate principal amount was outstanding under the Revolving Credit Facility.

Term Loan

In December 2017, the Company entered into a credit and security agreement with a lender (the “Term Loan Agreement”). The Term Loan Agreement provides for an initial term loan of $40.0 million with an additional tranche of $20.0 million available through December 31, 2018, if specified conditions are met (the “Term Loan”). In connection with the Amendment, the Company used a portion of the net proceeds from the initial advance to repay a portion of the outstanding borrowings under the Revolving Credit Facility. Interest on the Term Loan is payable monthly in arrears at an annual interest rate of 6.75% plus 90-day LIBOR. The Term Loan Agreement matures December 15, 2022 and, if prepaid, has fees equal to 3%, 2%, and 1% of the prepayment amount if such termination occurs within the first year, the second year, and the third year of funding, respectively. The term of the loan is 60 months with interest only for the first 24 months followed by straight-line amortization of principal for the remaining months. In addition, the Company will pay an annual administrative fee of 0.25% and a final payment of 4.0% of the Term Loan amount. As of September 30, 2018, $40.0 million of aggregate principal amount was outstanding.

The following table presents the carrying value of the Credit Facilities and 3.75% Convertible Notes (in thousands):

The following table presents details of share-based compensation expenses by functional line item (in thousands):

Note 12. Net Loss Per Common Share

The Company reports both basic and diluted loss per share, which is based on the weighted average number of common shares outstanding during the period.

A reconciliation of the numerator and denominator used in the calculation of basic and diluted net loss per common share follows (in thousands):

The potentially dilutive shares of the Company’s common stock resulting from the assumed exercise of outstanding stock options, the settlement of vested Restricted Stock Units (RSUs), Market Stock Units (MSUs) and Performance Stock Units (PSUs), and the purchase of shares under the Company’s Employee Stock Purchase Program (ESPP), as determined under the treasury stock method,

19

are excluded from the computation of diluted net loss per share because their effect would have been anti-dilutive. Additionally, the 3.50% Convertible Notes are included in the calculation of diluted net income per share only if their inclusion is dilutive.

The following table sets forth all potentially dilutive securities excluded from the computation in the table above because their effect would have been anti-dilutive (in thousands):

3.75% Convertible Notes—Diluted Share Impact

The 3.75% Convertible Notes and the 3.50% Series A Convertible Notes have an optional physical (share), cash or combination settlement feature and contain certain conditional conversion features. The 3.50% Series A Convertible Notes were retired in February 2018. Due to the optional cash settlement feature and management’s intent to settle the principal amount thereof in cash, the shares of our common stock issuable upon conversion of the outstanding principal amount of the 3.75% Convertible Notes as of September 30, 2018, totaling approximately 14.9 million shares of our common stock, were not included in the basic and diluted net loss per common share table above.

Note 13. Segment Information

The Company operates in one reportable segment (oncology systems group), which develops, manufactures and markets proprietary medical devices used in radiation therapy and radiosurgery 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.

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.

The following tables present net revenue and long-lived asset information based on geographic region. Net revenue is based on the destination of the shipments and long-lived assets are based on the physical location of the assets (in thousands):

Note 14. Income Tax

On a quarterly basis, the Company provides for income taxes based upon an estimated annual effective income tax rate. The Company recognized an income tax expense of $0.5 million and $0.8 million for the three months ended September 30, 2018 and 2017. respectively, primarily related to foreign taxes.

On December 22, 2017, the “Tax Cuts and Jobs Act” (the “Tax Act”) was signed into law making significant changes to the Internal Revenue Code (the “IRC”). Changes include, but are not limited to, reduction in the U.S. corporate tax rate from 35% to 21% effective for tax years beginning after December 31, 2017, limitations on the deductibility of executive compensation, interest expense, net operating loss, immediate expensing of capital expenditures, a one-time transition tax on the mandatory deemed repatriation of cumulative foreign earnings as of December 31, 2017 and the transition of the U.S. international taxation from a “worldwide” system to a territorial system of taxation and the introduction of a base erosion and anti-abuse tax.

In accordance with Staff Accounting Bulletin (SAB) No. 118 - Income Tax Accounting Implications of the Tax Cuts and Jobs Act, the effects of the Tax Act may be adjusted within a one-year measurement period from the enactment date for items that were previously reported as provisional, or where a provisional estimate could not be made. Income tax provision for the three months ended September 30, 2018, did not reflect any adjustment to the previously assessed Tax Act enactment effect. The Company will continue to assess forthcoming guidance and accounting interpretations on the effects of the Tax Act and expects to complete its analysis within the measurement period in accordance with the guidance provided in SAB No. 118.

The Tax Act has a requirement that certain income earned by controlled foreign corporations (“CFCs”) must be included currently in the gross income of the CFC’s U.S. shareholder. The income required to be included in gross income is referred to as global intangible low tax income (“GILTI”) and is as defined under IRC Section 951A as is 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 and is not expected to cause the Company to be in a U.S. taxable income position for fiscal year 2019. The Company has not recorded deferred taxes related to these GILTI provisions and has not yet determined its policy election with respect to whether it will treat GILTI as a current-period expense when incurred (the “period cost method”) or factor such amount into the measurement of deferred taxes (the “deferred method”).

In addition to the GILTI provision, the Tax Act also enacted the Base Erosion and Anti-Abuse Tax (“BEAT”). The BEAT minimum tax under IRC Section 59A is applicable to the extent that the BEAT tax amount is greater than the regular corporate tax for a given year. This tax is applicable to companies with prior 3-year average annual gross receipts exceeding $500 million. The Company does not currently meet this threshold since its current average annual gross receipts are less than $500 million.

Note 15. Subsequent Events

On October 29, 2018, the Company informed affected employees of a cost saving initiative designed to reduce operating costs through the elimination of approximately 5 percent of its global workforce. The Company expects to complete the cost saving initiative in the second quarter of fiscal 2019. The Company estimates the total cost of this initiative to be approximately $1.5 million to $2.0 million, which is expected to be recorded in the second quarter of fiscal 2019.

Overview

Products and Markets

We are a radiation oncology company that develops, manufactures, sells and supports precise, innovative treatment solutions that set the standard of care, with the aim of helping patients live longer, better lives. Our leading-edge technologies, the CyberKnife and TomoTherapy Systems, including Radixact Systems, the next generation TomoTherapy platform, are designed to deliver advanced radiation therapy including radiosurgery, stereotactic body radiation therapy, intensity modulated radiation therapy, image-guided radiation therapy and adaptive radiation therapy tailored to the specific needs of each patient. The CyberKnife and TomoTherapy Systems are complementary offerings serving largely separate patient populations treated by the same medical specialty, radiation oncology. Both systems have advanced capabilities that offer increased treatment flexibility to meet the needs of an expanding patient population including patients requiring retreatment with radiation therapy. We also offer comprehensive software solutions to enable and enhance the precise and efficient radiosurgery and radiotherapy treatment with our CyberKnife and TomoTherapy Systems. In addition to these products, we also provide services, which include post-contract customer support (warranty period services and post warranty services), installation services, training and other professional services.

The CyberKnife Systems

The CyberKnife Systems are robotic systems designed to deliver radiosurgery treatments to cancer tumors anywhere in the body. The CyberKnife Systems are the only dedicated, full-body robotic radiosurgery systems on the market. Radiosurgery is an alternative to traditional surgery for tumors and is performed on an outpatient basis in one to five treatment sessions. It enables the treatment of patients who typically might not otherwise be treated with radiation, who may not be good candidates for surgery, or who desire non-surgical treatments. The use of radiosurgery with CyberKnife Systems to treat tumors throughout the body has grown significantly in recent years, but currently only a small portion of the patients who develop tumors treatable with CyberKnife Systems are treated with these systems. A determination of when it may or may not be appropriate to use a CyberKnife System for treatment is at the discretion of the treating physician and depends on the specific patient. However, the CyberKnife Systems are generally not used to treat (1) very large tumors, which are considerably wider than the radiation beam that can be delivered by CyberKnife Systems, (2) diffuse wide-spread disease, as is often the case for late stage cancers, because they are not localized (though CyberKnife Systems might be used to treat a focal area of the disease) and (3) systemic diseases, like leukemia and lymphoma, which are not localized to an organ, but rather involve cells throughout the body.

22

Our CyberKnife M6 Series Systems have the option of: fixed collimator, Iris Variable Aperture Collimator and/or multi-leaf collimator, or InCise MLC. The InCise MLC is designed specifically for the M6 Series. With the InCise MLC, clinicians can deliver the same precise radiosurgery treatments they have come to expect with the CyberKnife System, faster and for a wider range of tumor types than prior CyberKnife systems. The InCise MLC makes it faster and more efficient to treat a wider range of tumor types with the CyberKnife M6 Series System, including larger tumors and those with multiple sites of disease.

We believe the long-term success of the CyberKnife Systems is dependent on a number of factors including the following:

TomoTherapy Systems, including Radixact, the next generation TomoTherapy platform

The TomoTherapy Systems are advanced, fully integrated and versatile radiation therapy systems for the treatment of a wide range of cancer types. The TomoTherapy Systems are specifically designed for image-guided intensity-modulated radiation therapy (IG-IMRT). The TomoTherapy Systems include the TomoTherapy H Series Systems with configurations of TomoH, TomoHD and TomoHDA. Based on a CT scanner platform, the systems provide continuous delivery of radiation from 360 degrees around the patient, or delivery from clinician-specified beam angles. These unique features, combined with daily 3D image guidance, enable physicians to deliver highly accurate, individualized dose distributions which precisely conform to the shape of the patient’s tumor while minimizing dose to normal, healthy tissue, resulting in fewer side effects for the patient. The TomoTherapy Systems are capable of treating all standard radiation therapy indications including breast, prostate, lung and head and neck cancers, in addition to complex and novel treatments such as total marrow irradiation. The Radixact System, the next generation TomoTherapy platform, includes our integrated Accuray Precision treatment planning software and new iDMS Data Management System. The Radixact System leverages the TomoTherapy System’s efficient daily low-dose fan beam MVCT image guidance and unique ring gantry architecture, delivering precise radiation treatments for more patients, faster, with simpler, more automated workflows. We believe the Radixact System and other TomoTherapy Systems offer clinicians and patients significant benefits over other radiation therapy systems in the market. We believe our ability to capture more sales will be influenced by a number of factors including the following:

23

Adoption of ASC 606

At the beginning of our fiscal year 2019, we adopted the new revenue recognition standard ASC 606, Revenues from Contracts with Customers and applied the modified retrospective method. All financial statements and disclosures have been adjusted to comply with ASC 606. See Note 1. The Company and its Significant Accounting Policies, Note 2. Recent Accounting Pronouncements and Note 3. Revenue of the Notes to the unaudited condensed consolidated financial statements, for additional information.

Sale of Our Products

Generating revenue from the sale of our systems is a lengthy process. Selling our systems, from first contact with a potential customer to a signed sales contract that meets our backlog criteria (as discussed below) varies significantly and generally spans between six months and two years. The length of time between receipt of a signed contract and revenue recognition is generally governed by the time required by the customer to build, renovate or prepare the treatment room for installation of the system.

In the United States, we primarily market directly to customers, including hospitals and stand-alone treatment facilities, through our sales organization and we also market to customers through sales agents and group purchasing organizations. Outside the United States, we market to customers directly and through distributors and sales agents. In addition to our offices in the United States, we have sales and service offices in Europe, Asia, and South America.

Backlog

Effective at the beginning of our fiscal 2019, we updated our backlog policy to include certain upgrades sold through service contracts. As a result, the portion of the order that is recognizable as product revenue and upgrades sold on service contracts are reported as backlog. The portion of the order that is recognized as other service revenue (for example, Post-Contract Customer Support (PCS), installation, training and professional services) is not included in reported backlog. As of September 30, 2018, backlog totaled $461.9 million, of which $1.1 million was due to the inclusion of upgrades sold through service contracts. As of June 30, 2018, backlog totaled $478.5 million.

In order for the product portion of a system sales agreement to be counted as backlog, it must meet the following criteria:

Although our backlog includes only contractual agreements with our customers for the purchase of CyberKnife Systems, TomoTherapy Systems, including Radixact Systems and related upgrades, we cannot provide assurance that we will convert backlog into recognized revenue due primarily to factors outside of our control. The amount of backlog recognized into revenue is primarily impacted by three items: cancellations, age-outs and foreign currency fluctuations. Orders could be cancelled for reasons including, without limitation, changes in customers’ needs or financial condition, changes in government or health insurance reimbursement policies, or changes to regulatory requirements. In addition to cancellations, after 2.5 years, if we have not been able to recognize revenue on a contract, we remove the revenue associated with the contract from backlog and the order is considered aged out. Contracts may age-out for many reasons, including but not limited to, inability of the customer to pay, inability of the customer to adapt their facilities to accommodate our products in a timely manner, or inability to timely obtain licenses necessary for customer facilities or operation of our equipment. Our backlog also includes amounts not denominated in U.S. Dollars and therefore fluctuations in the U.S. Dollar as compared to other currencies will impact revenue. Generally, strengthening of the U.S. Dollar will negatively impact revenue. Backlog is stated at historical foreign currency exchange rates, and revenue is released from backlog at current exchange rates, with any difference recorded as a backlog adjustment.

24

A summary of gross orders, net orders, and order backlog is as follows (in thousands):

Gross Orders

Gross orders are defined as the sum of new orders recorded during the period adjusted for any revisions to existing orders during the period.

Gross orders increased by $5.8 million for the three months ended September 30, 2018, as compared to the three months ended September 30, 2017. This was primarily a result of an increase of $4.7 million in new system order volume compared to the same prior year period, primarily related to a $14.0 million increase in TomoTherapy System orders driven by Radixact Systems, offset by $9.3 million decrease of CyberKnife System orders. In addition, there was a $1.1 million net increase in upgrade orders and other amendments as compared to the same prior year period, driven by the inclusion of upgrades from service contracts beginning July 1, 2018.

Net Orders

Net orders are defined as gross orders less cancellations, age-outs, foreign exchange and other adjustments during the period.

Net orders decreased by $26.1 million for the three months ended September 30, 2018, as compared to the three months ended September 30, 2017, resulting from an increase in net age-outs of $21.9 million, negative adjustments for the adoption of ASC 606 and foreign currency of $3.4 million, and an increase in cancellations of $6.6 million, offset by an increase in gross orders of $5.8 million.
