1. Summary of Significant Accounting Policies

Description of Business

Accuray Incorporated (together with its subsidiaries, the “Company” or “Accuray”) is incorporated in Delaware and has its principal place of business in Sunnyvale, California. The Company designs, develops and sells advanced radiosurgery and radiation therapy systems for the treatment of tumors throughout the body. The Company has offices in the United States, Switzerland, China and Japan and conducts its business worldwide.

Basis of Presentation and Principles of Consolidation

The 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 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, 2015 are not necessarily indicative of the results to be expected for the year ending June 30, 2016, for any other future interim period or future year.

These condensed consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements and accompanying notes for the year ended June 30, 2015 included in the Company’s Annual Report on Form 10-K filed with the SEC on August 28, 2015. The Company’s significant accounting policies are described in Note 2 to those audited consolidated financial statements and there have been no material changes to such policies.

Recent Accounting Standard Update Not Yet Effective

In May 2014, the FASB issued Accounting Standards Update No. 2014-09, Revenue from Contracts with Customers: Topic 606 (ASU 2014-09), to supersede nearly all existing revenue recognition guidance under GAAP. The core principle of ASU 2014-09 is to recognize revenues 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. On July 9, 2015, FASB approved a one-year deferral of the effective period for ASU 2014-09. The standard will be effective for the Company for the first quarter of fiscal 2019, but entities will be permitted to early adopt the standard as of the original effective date, which would be the first quarter of fiscal 2018 for the Company. The Company may adopt 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 as defined per ASU 2014-09. The Company has not yet selected a transition method, has not yet determined whether it will select early adoption and is currently evaluating the impact of pending adoption of ASU 2014-09 on its consolidated financial statements and related disclosures.

Use of Estimates

The preparation of condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosures at the date of the financial statements. Key estimates and assumptions made by the Company relate to revenue recognition, assessment of recoverability of goodwill and intangible assets, valuation of inventories, share-based compensation expense, income taxes, allowance for doubtful accounts, loss contingencies and corporate bonus expenses. Actual results could differ materially from those estimates.

Concentration of Credit and Other Risks

The Company’s cash, cash equivalents and investments are deposited with several major financial institutions. At times, deposits in these institutions exceed the amount of insurance provided on such deposits. The Company has not experienced any losses in such accounts and does not believe that it is exposed to any significant risk of loss on these balances.

For the three months ended December 31, 2015 and 2014, there were no customers that represented 10% or more of total net revenue.  For the six months ended December 31, 2015, there was one customer that represented 11% of total net revenue.  For the six months ended December 31, 2014, there were no customers that represented 10% or more of total net revenue.  No customer accounted for more than 10% of the Company’s total accounts receivable as of December 31, 2015.  One customer accounted for 18% of the Company’s total accounts receivable as of June 30, 2015.

Accounts receivable are typically not collateralized. The Company performs ongoing credit evaluations of its customers and maintains reserves for potential credit losses. Accounts receivable are deemed past due in accordance with the contractual terms of the agreement. Accounts are charged against the allowance for doubtful accounts once collection efforts are unsuccessful.

Single source suppliers presently provide the Company with several components. In most cases, if a supplier was unable to deliver these components, the Company believes that it would be able to find other sources for these components subject to any regulatory qualifications, if required.

Revenue Recognition

The Company earns revenue from the sale of products and related services. The Company records its revenues net of any value added or sales tax. For arrangements with multiple elements, the Company allocates arrangement fees to products and services based upon Vendor Specific Objective Evidence (“VSOE”) of fair value of the respective elements, Third-Party Evidence (“TPE”), or Best Estimate of Selling Price (“BESP”), using the relative selling price method.

Product and Service Revenue

The majority of product revenue is generated from sales of CyberKnife and TomoTherapy systems. If the Company is responsible for installation, the Company recognizes revenue after installation and acceptance of the system. Otherwise, revenue is recognized upon delivery, assuming all other revenue recognition criteria are met.

The Company offers its systems with post-contract customer support (“PCS”) contracts, installation services, training and professional services. PCS contracts provide planned and corrective maintenance services, software updates, bug fixes, as well as call-center support. Service revenue is generated primarily from PCS (warranty period services and post warranty services), installation services, training, parts and upgrades that are sold under service contracts and professional services. PCS revenue is deferred and recognized over the service period. Installation service revenue is recognized concurrent with system revenue. Training and professional service revenues that are not deemed essential to the functionality of the systems are recognized as such services are performed.

Costs associated with service revenue are expensed when incurred, except when those costs are related to parts or system upgrades where revenue recognition has been deferred. In those cases, the costs are deferred and are recognized over the period of revenue recognition.

Net Loss Per Common Share

Basic and diluted net loss per share is computed by dividing net loss attributable to stockholders by the weighted average number of common shares outstanding during the period.

7

Table of Contents

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

The potentially dilutive shares of the Company’s common stock resulting from the assumed exercise of outstanding stock options, the vesting of Restricted Stock Units (RSU), Market Stock Units (MSU) and Performance Stock Units (PSU), and the purchase of shares under the Employee Stock Purchase Program (ESPP), as determined under the treasury stock method, are excluded from the computation of diluted net loss per share because their effect would have been anti-dilutive. Additionally, the 3.75% Convertible Senior Notes due August 1, 2016 (the “3.75% Convertible Notes”), the 3.50% Convertible Senior Notes due February 1, 2018 (the “3.50% Convertible Notes”) and the 3.50% Series A Convertible Notes (the “3.50% Series A Convertible Notes”) due February 1, 2018 (together, the “Convertible Notes”) are included in the calculation of diluted net income per share only if their inclusion is dilutive. For the three months ended December 31, 2015 and 2014, respectively, the potentially dilutive shares under the Convertible Notes were excluded from the calculation of diluted net loss per share as their inclusion would have been anti-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):

Outstanding Convertible Notes—Diluted Share Impact

The 3.75% Convertible Notes and 3.50% Series A Convertible Notes have an optional physical (share), cash or combination settlement feature and contain certain conditional conversion features. Due to the optional cash settlement feature and management’s intent to settle the principal amount thereof in cash, the conversion shares underlying the outstanding principal amount of the 3.75% Convertible Notes and the 3.50% Series A Convertible Notes, totaling approximately 10.6 million shares and 13.2 million shares, respectively, were not included in the potentially diluted share count table above. The Company’s average stock price did not exceed the conversion price of the 3.75% Convertible Notes as of December 31, 2015 and 2014, respectively. The 2.8 and 3.9 million potentially dilutive shares of the 3.50% Series A Convertible Notes as of December 31, 2015 and 2014, respectively, included in the table above represent the premium over the principal amount due to the higher average share price above the conversion price. The number of premium shares included in the Company’s diluted share count will vary with fluctuations in the Company’s share price. Higher actual share prices result in a greater number of premium shares.

Segment Information

The Company has determined that it operates in only one segment, as it only reports profit and loss information on an aggregate basis to its chief operating decision maker. Revenue by geographic region is based on the shipping addresses of the Company’s customers. The following summarizes revenue by geographic region (in thousands):

2. 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 $8.1 million and $1.6 million at December 31, 2015 and June 30, 2015, respectively, and are included in Other Assets in the consolidated balance sheets. There was no balance in the allowance for doubtful accounts related to such financing receivables as of December 31, 2015 and June 30, 2015, respectively, as revenue is recognized on a cash basis for these receivables.

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 and six months ended December 31, 2015 was $2.5 million and $5.1 million, respectively.  Depreciation expense related to property and equipment for the three and six months ended December 31, 2014 was $3.0 million and $6.0 million, respectively.

3. Goodwill and Intangible Assets

Goodwill

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

In the second quarter of fiscal 2016, 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 unamortized intangible assets associated with completed acquisitions at December 31, 2015 and June 30, 2015 are 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 December 31, 2015 and June 30, 2015.

Amortization expense related to intangible assets for the three and six months ended December 31, 2015 was $2.0 million and $4.0 million, respectively. Amortization expense related to intangible assets for the three and six months ended December 31, 2014 was $2.0 million and $4.0 million, respectively.

The estimated future amortization expense of purchased intangible assets as of December 31, 2015 is as follows (in thousands):

4. Financial Instruments

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 it is management’s intent 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 (loss), a

10

Table of Contents

component of stockholders’ equity. Realized gains and losses are recorded based on specific identification of each security’s cost basis.

The Company defines fair value as the price that would be received to sell an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. 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.

The following tables summarize the amortized cost, gross unrealized gains, gross unrealized losses and fair value by significant investment category for cash, cash equivalents and short-term investments (in thousands):

11

Table of Contents

The Company’s Level 2 investments in the table above are classified as Level 2 items because quoted prices in an active market are not readily accessible for those specific financial assets, or the Company may have relied on alternative pricing methods that do not rely exclusively on quoted prices to determine the fair value of the investments.

The Company had investments that were in an unrealized loss position as of December 31, 2015. The Company determined that (i) it does not have the intent to sell any of these investments and (ii) it is not likely that it will be required to sell any of these investments before recovery of the entire amortized cost basis. The Company reviews its investments quarterly to identify and evaluate investments that have an indication of possible impairment. As of December 31, 2015, the Company anticipates that it will recover the entire carrying value of such investments and has determined that no other-than-temporary impairments associated with credit losses were required to be recognized during the six months ended December 31, 2015.

Contractual maturities of available-for-sale securities at December 31, 2015 were as follows (in thousands):

The following table summarizes the carrying values and estimated fair values of our short-term and long-term debt (in thousands):

The short-term and long-term 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 Convertible Notes is not readily available.

5. Commitments and Contingencies

The Company’s contractual obligations were presented in the Annual Report on Form 10-K for the previous annual reporting period ended June 30, 2015. There have been no material changes outside of the ordinary course of business in those obligations during the three months ended December 31, 2015.

Table of Contents

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 any current legal proceedings and claims. Although occasional adverse decisions or settlements may occur, except as described in the matters below, 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. For certain legal proceedings, management believes that there is a reasonable possibility that material losses may be incurred; however, the Company is unable to reasonably estimate a range of reasonably possible losses with respect to these matters. 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.

Rotary Systems

On April 28, 2011, a former supplier to TomoTherapy, Rotary Systems Incorporated (“Rotary Systems”), filed suit in Minnesota state court, Tenth Judicial District, Anoka County, against TomoTherapy alleging misappropriation of trade secrets, as well as several other counts alleging various theories of injury. Rotary Systems alleges TomoTherapy misappropriated Rotary Systems’ trade secrets pertaining to a component previously purchased from Rotary Systems, which TomoTherapy now purchases from a different supplier. The suit alleges TomoTherapy improperly supplied the alleged trade secrets to its present supplier, Dynamic Sealing Technologies Inc. (also a named defendant in the suit). Rotary Systems has made an unspecified claim for damages of greater than $50,000. TomoTherapy moved to dismiss the case and, on August 29, 2011, the court granted the motion to dismiss with respect to all counts other than the count alleging misappropriation of trade secrets. On May 21, 2012, the court gave Rotary Systems sixty days to identify the alleged trade secrets with specificity or face dismissal of its claim with prejudice. The court held a hearing on September 20, 2012 to review Rotary Systems’ amended complaint. TomoTherapy filed a motion for summary judgment on the trade secret claim, the court ruled in favor of TomoTherapy on December 5, 2013, and Rotary Systems appealed.  On December 22, 2014, the Minnesota Court of Appeals reversed the district court’s dismissal of Rotary Systems’ trade secrets claim and remanded it to the district court but affirmed the dismissal of Rotary Systems’ other claims. In late October 2015, a final scheduling order was confirmed for the remanded claims and the parties are currently in the process of conducting discovery.

Cowealth Medical

On February 27, 2014, Cowealth Medical Holding Co., Ltd. (“Cowealth”), Accuray’s former distributor in China, submitted a request for binding arbitration with the International Chamber of Commerce International Court of Arbitration (“ICC”) alleging, among other matters, that Accuray breached its distributor agreement with Cowealth by wrongfully terminating Cowealth as its distributor and misappropriated certain of Cowealth’s confidential information. Cowealth was seeking damages of approximately $170.0 million and injunctive relief. Accuray filed counterclaims for damages of approximately $35.0 million. Accuray’s answer and counterclaim were submitted to the ICC on May 12, 2014, and Cowealth served its reply on June 27, 2014. A hearing was held in Hong Kong between January 26, 2015 and February 6, 2015. The parties filed closing submissions and reply closing submissions in March 2015. On October 29, 2015, the ICC ruled that Accuray was liable for certain damages and awarded Cowealth approximately $3.4 million. On November 27, 2015, Cowealth applied for a correction to the award to revise the amount of damages upwards to approximately $5.5 million. On January 21, 2016, the arbitrator granted Cowealth’s application for a correction on the grounds that the original award amount was a clerical error on the part of the arbitrator. Interest on the final award amount will accrue at a rate of 5% per annum starting 30 days after the date the corrected award was issued until payment. Accordingly, management recorded a charge of $3.4 million for the first fiscal quarter ending September 30, 2015, and an additional $2.1 million for the second fiscal quarter ending December 30, 2015. The parties filed cost submissions and reply cost submissions in December 2015. The ICC will subsequently issue a separate ruling as to legal costs and associated expenses; however, management does not believe the likelihood of an award of legal fees to Cowealth is probable or estimable as of December 31, 2015, so no additional amount has been recorded. Prior to the ruling of the ICC, no accrual was established in the Company’s consolidated financial statements because management did not believe the likelihood of an award of damages to Cowealth was probable or estimable. In addition, the Company won several of its counterclaims including the right to be assigned the existing service contracts between Cowealth and Accuray customers, transfer to Accuray any regulatory clearances, licenses or permits obtained and held for the purposes of selling the CyberKnife System in China and deliver any consigned parts in their possession.

Software License Indemnity

Under the terms of the Company’s software license agreements with its customers, the Company agrees that in the event the software sold infringes upon any patent, copyright, trademark, or any other proprietary right of a third-party, it will indemnify its

13

Table of Contents

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, 2015.

The following table summarizes the share-based compensation charges included in the Company’s condensed consolidated statements of operations and comprehensive loss (in thousands):

7. Debt

3.75% Convertible Senior Notes due August 2016

On August 1, 2011, the Company issued the 3.75% Convertible Notes to certain qualified institutional buyers, or QIBs. The 3.75% Convertible Notes were offered and sold to the QIBs pursuant to Rule 144A under the Securities Act of 1933, as amended (the “Securities Act”), or Rule 144A. The net proceeds from the $100 million offering, after deducting the initial purchaser’s discount and commission and the related offering costs, were approximately $96.1 million. The offering costs and the initial purchaser’s discount and commission (which are recorded in Other Assets) are both being amortized to interest expense using the effective interest method over five years. The 3.75% Convertible Notes bear interest at a rate of 3.75% per year, payable semi-annually in arrears in cash on February 1 and August 1 of each year, beginning on February 1, 2012. The 3.75% Convertible Notes will mature on August 1, 2016, unless earlier repurchased, redeemed or converted.  A portion of these notes were redeemed in January 2016, as noted in Note 9 below.

The 3.75% Convertible Notes were issued under an Indenture between the Company and The Bank of New York Mellon Trust Company, N.A., as trustee. Holders of the 3.75% Convertible Notes may convert their 3.75% Convertible Notes at any time on or after May 1, 2016 until the close of business on the business day immediately preceding the maturity date. Prior to May 1, 2016, holders of the 3.75% Convertible Notes may convert their 3.75% Convertible Notes only under the following circumstances: (1) during any calendar quarter after the calendar quarter ending September 30, 2011, and only during such calendar quarter, if the closing sale price of the Company’s common stock for each of 20 or more trading days in the 30 consecutive trading days ending on the last trading day of the immediately preceding calendar quarter exceeds 130% of the conversion price in effect on the last trading day of the immediately preceding calendar quarter; (2) during the five consecutive business days immediately after any five consecutive trading-day period (such five consecutive trading-day period, the “Note Measurement Period”) in which the trading price per $1,000 principal amount of 3.75% Convertible Notes for each trading day of that Note Measurement Period was equal to or less than 98% of the product of the closing sale price of shares of the Company’s common stock and the applicable conversion rate for such trading day; (3) if the Company calls any or all of the 3.75% Convertible Notes for redemption, at any time prior to the close of business on the business day immediately preceding the redemption date; or (4) upon the occurrence of specified corporate transactions as described in the Indenture. Upon conversion by holders of the 3.75% Convertible Notes, the Company will have the right to pay or deliver, as the case may be, cash, shares of common stock of the Company or a combination thereof, at the Company’s election. At any time on or prior to the 33rd business day immediately preceding the maturity date, the Company may irrevocably elect to (a) deliver solely shares of common stock of the Company in respect of the Company’s conversion obligation or (b) pay cash up to the aggregate principal amount of the 3.75% Convertible Notes to be converted and pay or deliver, as the case may be, cash, shares of common stock of the Company or a combination thereof in respect of the remainder, if any, of the Company’s conversion obligation in excess of the aggregate principal amount of the 3.75% Convertible Notes being converted. The initial conversion rate is 105.5548 shares of the Company’s common stock per $1,000 principal amount of 3.75% Convertible Notes (which represents an initial conversion price of approximately $9.47 per share of the Company’s common stock). The conversion rate, and thus the conversion price, are subject to adjustment as further described below.

14

Table of Contents

Holders of the 3.75% Convertible Notes who convert their 3.75% Convertible 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 3.75% Convertible Notes at a fundamental change repurchase price equal to 100% of the principal amount of 3.75% Convertible Notes, plus accrued and unpaid interest, if any, to, but not including, the fundamental change repurchase date.

Prior to the maturity date, the Company may redeem for cash all or a portion of the 3.75% Convertible Notes if the closing sale price of its common stock exceeds 130% of the applicable conversion price (the initial conversion price is approximately $9.47 per share of common stock) of such 3.75% Convertible Notes for at least 20 trading days during any consecutive 30 trading-day period (including the last trading day of such period).

In accordance with ASC 470-20, Debt with Conversion and Other Options, the Company separately accounts for the liability and equity conversion components of the 3.75% Convertible Notes. The principal amount of the liability component of the 3.75% Convertible Notes was $75.9 million as of the date of issuance based on the present value of its cash flows using a discount rate of 10%, our approximate borrowing rate at the date of the issuance for a similar debt instrument without the conversion feature. The carrying value of the equity conversion component was $24.1 million. A portion of the initial purchaser’s discount and commission and the offering costs totaling $0.9 million was allocated to the equity conversion component. The liability component is being accreted to the principal amount of the 3.75% Convertible Notes using the effective interest method over five years.  A portion of these notes were repurchased in January 2016, please refer to Note 9 below.

3.50% Convertible Senior Notes due February 2018

In February 2013, the Company issued $115.0 million aggregate principal amount of its 3.50% Convertible Notes to certain QIBs. The 3.50% Convertible Notes were offered and sold to the QIBs pursuant to Rule 144A. The net proceeds from the offering, after deducting the initial purchaser’s discount and commission and the related offering costs, were approximately $110.5 million. The offering costs and the initial purchaser’s discount and commission (which are recorded in Other Assets) are both being amortized to interest expense using the effective interest method over five years. The 3.50% Convertible Notes bear interest at a rate of 3.50% per year, payable semi-annually in arrears in cash on February 1 and August 1 of each year, which began on August 1, 2013. The 3.50% Convertible Notes will mature on February 1, 2018, unless earlier repurchased, redeemed or converted.

In April 2014, through a series of transactions, the Company refinanced approximately $70.3 million aggregate principal amount of the 3.50% Convertible Notes with approximately $70.3 million aggregate principal amount of the Company’s new 3.50% Series A Convertible Senior Notes due 2018 (the “3.50% Series A Convertible Notes”).

The 3.50% Convertible Notes were issued 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 may convert their 3.50% Convertible Notes at any time until the close of business on the business day immediately preceding the maturity date. The 3.50% Convertible Notes are convertible, as described below into common stock of the Company at an initial conversion rate equal to 187.6877 shares of common stock per $1,000 principal amount of the 3.50% Convertible Notes, which is equivalent to a conversion price of approximately $5.33 per share of common stock, subject to adjustment.

Holders of the 3.50% Convertible Notes who convert their 3.50% Convertible 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 3.50% Convertible Notes may require the Company to purchase all or a portion of their 3.50% Convertible Notes at a fundamental change repurchase price equal to 100% of the principal amount of 3.50% Convertible Notes, plus accrued and unpaid interest, if any, to, but not including, the fundamental change repurchase date.

In accordance with guidance in ASC 470-20, Debt with Conversion and Other Options and ASC 815-15, Embedded Derivatives, the Company determined that the embedded conversion components of the 3.50% Convertible Note do not require bifurcation and separate accounting. The remaining $44.7 million principal amount of the 3.50% Convertible Note has been recorded in Long-term Debt on the consolidated balance sheet as of December 31, 2015.

with approximately $70.3 million aggregate principal amount of the 3.50% Series A Convertible Notes. Pursuant to the note exchange agreements, the Company also paid the Participating Holders an aggregate of approximately $0.4 million in cash in connection with such transactions. The principal amount of 3.50% Convertible Notes refinanced for each $1,000 principal amount of the 3.50% Series A Convertible Notes was $1,000 and the amount in cash paid per $1,000 principal amount of such 3.50% Convertible Notes delivered was determined in individual negotiations between the Company and each Participating Holder. The Series A Convertible Notes have the same interest rate, maturity and other terms as the 3.50% Convertible Notes, except that the 3.50% Series A Convertible Notes are convertible into cash, shares of the Company’s common stock or a combination of cash and shares of common stock, at the Company’s option.

The 3.50% Series A Convertible Notes were issued 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 may convert their Securities at any time on or after November 1, 2017 until the close of business on the business day immediately preceding the maturity date. Prior to November 1, 2017, holders of the 3.50% Series A Convertible Notes may convert their Securities only under the following circumstances: (1) during any calendar quarter after the calendar quarter ending September 30, 2014, and only during such calendar quarter, if the closing sale price of the Company’s common stock for each of 20 or more trading days in the 30 consecutive trading days ending on the last trading day of the immediately preceding calendar quarter exceeds 130% of the conversion price in effect on the last trading day of the immediately preceding calendar quarter; (2) during the five consecutive business days immediately after any five consecutive trading-day period (such five consecutive trading-day period, the “Note Measurement Period”) in which the trading price per $1,000 principal amount of 3.50% Series A Convertible Notes for each trading day of that Securities Measurement Period was equal to or less than 98% of the product of the closing sale price of shares of the Company’s common stock and the applicable conversion rate for such trading day; or (3) upon the occurrence of specified corporate transactions as described in the Indenture. Upon conversion by holders of the 3.50% Series A Convertible Notes, the Company will have the right to pay or deliver, as the case may be, cash, shares of common stock of the Company or a combination thereof, at the Company’s election. At any time on or prior to the 17th business day immediately preceding the maturity date, the Company may irrevocably elect to (a) deliver solely shares of common stock of the Company in respect of the Company’s conversion obligation or (b) pay cash up to the aggregate principal amount of the 3.50% Series A Convertible Notes to be converted and pay or deliver, as the case may be, cash, shares of common stock of the Company or a combination thereof in respect of the remainder, if any, of the Company’s conversion obligation in excess of the aggregate principal amount of the 3.50% Series A Convertible Notes being converted. The initial conversion rate is 187.6877 shares of the Company’s common stock per $1,000 principal amount of 3.50% Series A Convertible Notes (which represents an initial conversion price of approximately $5.33 per share of the Company’s common stock). The conversion rate, and thus the conversion price, are subject to adjustment as further described below.

Holders of the 3.50% Series A 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 3.50% Series A Convertible Notes may require the Company to purchase all or a portion of their 3.50% Convertible Notes at a fundamental change repurchase price equal to 100% of the principal amount of the 3.50% Series A Convertible Notes, plus accrued and unpaid interest, if any, to, but not including, the fundamental change repurchase date.

In accordance with Accounting Standards Codification, or ASC 470-20, Debt with Conversion and Other Options, the Company separately accounts for the liability and equity conversion components of the 3.50% Series A Convertible Notes. The principal amount of the liability component of the 3.50% Series A Convertible Notes was $62.5 million as of the date of issuance based on the present value of its cash flows using a discount rate of 7%, our approximate borrowing rate at the date of the issuance for a similar debt instrument without the conversion feature. The carrying value of the equity conversion component was $7.9 million. In addition, the portion of the cash amount paid to the Participating Holders totaling $0.4 million was allocated to the debt discount with the remaining $47,000 to the equity component. The liability component is being accreted to the principal amount of the 3.50% Series A Convertible Notes using the effective interest method through the maturity in February 2018.

8. Accumulated Other Comprehensive Loss

The components of accumulated other comprehensive loss consist of net loss, unrealized gains and losses on available-for-sale investments, changes in foreign currency exchange rate translation and net changes related to defined benefit pension plan. These components are excluded from earnings and reported as a component of stockholders’ equity. The foreign currency translation adjustment results from those subsidiaries not using the United States dollar as their functional currency since the majority of their economic activities are primarily denominated in their applicable local currency. Accordingly, all assets and liabilities related to these operations are translated at the current exchange rates at the end of each period. The resulting cumulative translation adjustments are recorded directly to the accumulated other comprehensive loss account in stockholders’ equity. Revenues and expenses are translated at average exchange rates in effect during the period.

The components of accumulated other comprehensive loss in the equity section of the balance sheets are as follows (in thousands):
