Description of Business and Summary of Significant Accounting Policies

Description of Business

Maxwell Technologies, Inc. is a Delaware corporation originally incorporated under the name Maxwell Laboratories, Inc. in 1965. The Company made an initial public offering of common stock on the NASDAQ Stock Market in 1983, and changed its name to Maxwell Technologies, Inc. in 1996. The Company is headquartered in San Diego, California, and has two manufacturing facilities located in Yongin, South Korea and Peoria, Arizona. In addition, the Company uses two contract manufacturers located in China.

The Company develops, manufactures and markets energy storage and power delivery products for transportation, grid energy storage, industrial and other applications. The Company’s ultracapacitor products are energy storage devices that possess a unique combination of high power density, extremely long operational life and the ability to charge and discharge very rapidly. The Company’s ultracapacitor cells, multi-cell packs, modules and subsystems provide highly reliable energy storage and power delivery solutions for applications in multiple industries, including automotive, grid energy storage, wind, bus, industrial and truck. The Company’s lithium-ion capacitors are energy storage devices with the power characteristics of an ultracapacitor combined with the enhanced energy storage capacity approaching that of a battery and are uniquely designed to address a variety of applications in the rail, grid, and industrial markets where energy density and weight are differentiating factors.

In addition to its energy storage product line, the Company has developed and transformed its patented, proprietary and fundamental dry electrode manufacturing technology that has historically been used to make ultracapacitors to create a new technology that can be applied to the manufacturing of batteries, which we believe can create significant performance and cost benefits as compared to today’s state of the art lithium-ion batteries.

In December 2018, the Company sold its high voltage capacitor product line. High voltage’s CONDIS® capacitor products included grading and coupling capacitors, electric voltage transformers and metering products that are used to ensure the safety and reliability of electric utility infrastructure and other applications involving transport, distribution and measurement of high-voltage electrical energy. The results of the high voltage product line are included in discontinued operations.

In April 2017, the Company acquired substantially all of the assets and business of Nesscap Energy, Inc. (“Nesscap”), a developer and manufacturer of ultracapacitor products for use in transportation, renewable energy, industrial and consumer markets. The acquisition added complementary businesses to the Company’s operations and expanded the Company’s portfolio of ultracapacitor products.

The Company’s products are designed and manufactured to perform reliably for the life of the products and systems into which they are integrated. The Company achieves high reliability through the application of proprietary technologies and rigorously controlled design, development, manufacturing and test processes.

Financial Statement Presentation

The accompanying consolidated financial statements include the accounts of Maxwell Technologies, Inc. and its subsidiaries and have been prepared in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”). All intercompany transactions and account balances have been eliminated in consolidation.

During the fourth quarter of 2018, the Company sold its high voltage capacitor product line. The divestiture of the high voltage product line met the definition of a strategic shift that has a significant effect on the Company’s operations and financial results; therefore, the results of operations for the high voltage product line have been presented as discontinued operations in accordance with ASC 205-20, Presentation of Financial Statements-Discontinued Operations for all periods presented. Additionally, high voltage’s assets and liabilities as of December 31, 2017 are separately presented as related to discontinued operations on the consolidated balance sheet. Unless otherwise noted, discussion within these notes to the consolidated financial statements relates to continuing operations. Refer to Note 9 for additional information on discontinued operations.

Liquidity

On December 19, 2018, the Company entered into a Share Purchase Agreement with RN C Holding SA, a special purpose holding entity and affiliate of Renaissance Investment Foundation, (“Renaissance”), providing for the sale of 100% of the shares of the Company’s Swiss subsidiary, Maxwell Technologies SA (“Maxwell SA”), and its high voltage capacitor product line to Renaissance. The transaction simultaneously closed with the signing of the Share Purchase Agreement on December 19, 2018. The upfront purchase price was approximately $55.1 million, which after certain reductions and other transaction-related expenses resulted in net upfront cash proceeds of approximately $47.8 million.

In August 2018, the Company completed a public offering of 7,590,000 shares of its common stock at a public offering price of $3.25 per share. The Company received total net proceeds of approximately $23.0 million from the offering, after deducting underwriting discounts, commissions and offering expenses.

As of December 31, 2018, the Company had approximately $58.0 million in cash and cash equivalents, and working capital of $86.1 million. In addition, the Company has a revolving line of credit with East West Bank (the “Revolving Line of Credit”), under which no borrowings were outstanding as of December 31, 2018. As of December 31, 2018, the amount available under the Revolving Line of Credit was $10.5 million. This facility is scheduled to expire in May 2021. Management believes the available cash balance will be sufficient to fund operations, obligations as they become due, and capital investments for at least the next twelve months.

Reclassifications

The divestiture of the high voltage product line during the fourth quarter of 2018 met the definition of a strategic shift that has a significant effect on the Company’s operations and financial results; therefore, the results of operations for the high voltage product line have been reclassified as discontinued operations for all periods presented. Additionally, high voltage’s assets and liabilities as of December 31, 2017 have been reclassified and are now separately presented as related to discontinued operations on the consolidated balance sheet.

In accordance with the Company’s adoption of ASU No. 2017-07, non-service cost expense and income related to defined benefit plans were reclassified to “other components of defined benefit plans, net” for the year ended December 31, 2017. See further information under Recent Accounting Pronouncements below.

Interest income of $79,000 for the year ended December 31, 2017 which was previously included in “interest expense, net” has been reclassified to “other income” in the consolidated statement of operations, to conform to the current period presentation.

“Unrealized loss on foreign currency exchange rates” for the year ended December 31, 2017 has been reclassified to “trade and other accounts receivable” in the consolidated statements of cash flows, to conform to the current period presentation.

Use of Estimates

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect reported amounts and related disclosures. These estimates include, but are not limited to, assessing the collectability of accounts receivable, applied and unapplied production costs, production capacities, the usage and recoverability of inventories and long-lived assets, deferred income taxes, the incurrence of warranty obligations, the fair value of acquired tangible and intangible assets, impairment of goodwill and intangible assets, estimation of the cost to complete certain projects, estimation of pension and other defined benefit plan assets and liabilities, accruals for estimated losses for legal matters, and estimation of the value of stock-based compensation awards, including the probability that the performance criteria of restricted stock unit awards will be met.

Cash and Cash Equivalents

Cash and cash equivalents consist primarily of cash in readily available checking and money market accounts. Cash equivalents consist of highly liquid investments that are readily convertible to cash and that mature within three months or less from the date of purchase. The carrying amounts approximate fair value due to the short maturities of these instruments.

Accounts Receivable and Allowance for Doubtful Accounts

Trade receivables are stated at gross invoiced amount less an allowance for uncollectible accounts. The allowance for doubtful accounts reflects management’s best estimate of probable losses inherent in the accounts receivable balance. Management determines the allowance for doubtful accounts based on known troubled accounts, historical experience and other currently available evidence.

Inventories

Inventories are stated at the lower of cost (first-in first-out basis) or net realizable value. Finished goods and work-in-process inventory values include the cost of raw materials, labor and manufacturing overhead. Inventory when written down to net realizable value establishes a new cost basis and its value is not subsequently increased based upon changes in underlying facts and circumstances. The Company also makes adjustments to reduce the carrying amount of inventories for estimated excess or obsolete inventories. Factors influencing these adjustments include inventories on-hand compared with historical and estimated future sales for existing and new products and assumptions about the likelihood of obsolescence.

The Company utilizes contract manufacturers for manufacturing and assembly of some of its products. In 2018, the Company entered into an agreement with a new contract manufacturer in Asia. The terms of the agreement include the storage of Company owned electrode materials at the contract manufacturer’s facility which the Company records as consigned inventory. Additionally, the contract manufacturer is required to procure and stock raw materials sufficient to meet Maxwell’s forecasts, that, once processed, the Company is obligated to repurchase as finished goods; therefore, the Company also records these materials as consigned inventory and consigned inventory liability. The agreement with the contract manufacturer also requires a certain quarterly purchase commitment by the Company, and indicates that should the Company not meet its quarterly purchase commitment, an adjustment to the price shall be negotiated for the reduced purchase amount.

Property and Equipment

Property and equipment are carried at cost and are depreciated using the straight-line method. Depreciation is provided over the estimated useful lives of the related assets (three to ten years). Leasehold improvements are depreciated over the shorter of their estimated useful life or the term of the lease. Leasehold improvements funded by landlords are recorded as property and equipment, which is depreciated over the shorter of the estimated useful life of the asset or the lease term, and deferred rent, which is amortized over the lease term. As of December 31, 2018 and 2017, the net book value of leasehold improvements funded by landlords was $1.0 million and $1.2 million, respectively. As of December 31, 2018 and 2017, the unamortized balance of deferred rent related to landlord funding of leasehold improvements was $1.0 million and $1.2 million, respectively, which is included in “accounts payable and accrued liabilities” and “other long-term liabilities” in the consolidated balance sheets. In 2018, in connection with a transition to a new contract manufacturer, the Company recorded leased equipment of $1.9 million for production line equipment located at the contract manufacturer’s facility that met the definition of a capital lease, which will be depreciated over the three-year term of the agreement.

Goodwill

Goodwill, which represents the excess of the cost of an acquired business over the net fair value assigned to its assets and liabilities, is not amortized. Instead, goodwill is assessed annually at the reporting unit level for impairment under the Intangibles—Goodwill and Other Topic of the FASB ASC. The Company has established December 31 as the annual impairment test date. In addition, the Company assesses goodwill in between annual test dates if an event occurs or circumstances change that could more likely than not reduce the fair value of a reporting unit below its carrying value. The Company first makes a qualitative assessment as to whether goodwill is impaired. If it is more likely than not that goodwill is impaired, the Company performs a quantitative impairment analysis to determine if goodwill is impaired. The Company may also determine to skip the qualitative assessment in any year and move directly to the quantitative test. The quantitative goodwill impairment analysis compares the reporting unit’s carrying amount to its fair value. Goodwill impairment is recorded for any excess of a reporting unit's carrying amount over its fair value, not to exceed the total amount of goodwill allocated to the reporting unit. No impairments of goodwill were reported during the years ended December 31, 2018 and 2017. Also see Note 5, Goodwill and Intangible Assets, for further discussion of the Company’s goodwill impairment analysis.

Long-Lived Assets and Intangible Assets

The Company records intangible assets at their respective estimated fair values at the date of acquisition. Intangible assets are amortized based upon the pattern in which their economic benefit will be realized, or if this pattern cannot be reliably determined, using the straight-line method over their estimated useful lives of eight to fourteen years.

The Company reviews long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of the assets, including intangible assets, may not be recoverable. When such events occur, the Company compares the carrying amounts of the assets to their undiscounted expected future cash flows. If the Company determines that the carrying value of the asset is not recoverable, a permanent impairment charge is recorded for the amount by which the carrying value of the long-lived asset exceeds its fair value. During each of the years ended December 31, 2018 and 2017, the Company recorded impairment charges of $0.2 million. These impairment charges related to property and equipment which were no longer forecasted to be utilized during their remaining useful lives and for which the fair values approximated zero.

Warranty Obligation

The Company provides warranties on all product sales for terms ranging from one to eight years. The Company accrues for the estimated warranty costs at the time of sale based on historical warranty experience plus any known or expected changes in warranty exposure. As of December 31, 2018 and 2017, the accrued warranty liability included in “accounts payable and accrued liabilities” in the consolidated balance sheets was $0.9 million and $1.3 million, respectively.

Convertible Debt

Convertible notes are regarded as compound instruments, consisting of a liability component and an equity component. The component parts of compound instruments are classified separately as financial liabilities and equity in accordance with the substance of the contractual arrangement. At the date of issue, the fair value of the liability component is estimated using the prevailing market interest rate for a similar non-convertible instrument. This amount is recorded as a liability on an amortized cost basis until extinguished upon conversion or at the instrument’s maturity date. The equity component is determined by deducting the amount of the liability component from the proceeds of the compound instrument as a whole. This is recognized as additional paid-in capital and included in equity, net of income tax effects, and is not subsequently remeasured. After initial measurement, the convertible notes are carried at amortized cost using the effective interest method.

Income Taxes

Deferred income taxes are provided on a liability method in accordance with the Income Taxes Topic of the FASB ASC, whereby deferred tax assets are recognized for deductible temporary differences and deferred tax liabilities are recognized for taxable temporary differences. Under this method, deferred income taxes are recorded to reflect the tax consequences on future years of temporary differences between the tax basis of assets and liabilities and their reported amounts at each period end. If it is more likely than not that some portion or all of a deferred tax asset will not be realized, a valuation allowance is recognized. The guidance also provides criteria for the recognition, measurement, presentation and disclosures of uncertain tax positions. A tax benefit from an uncertain tax position may be recognized if it is “more likely than not” that the position is sustainable based solely on its technical merits.

Concentration of Credit Risk

The Company maintains cash balances at various financial institutions primarily in California. Cash balances commonly exceed the $250,000 Federal Deposit Insurance Corporation insurance limit. The Company has not experienced any losses in such accounts and management believes that the Company is not exposed to any significant credit risk with respect to such cash and cash equivalents.

Financial instruments, which subject the Company to potential concentrations of credit risk, consist principally of the Company’s accounts receivable. The Company’s accounts receivable result from product sales to customers in various industries and in various geographical areas, both domestic and foreign. The Company performs credit evaluations of its customers and generally requires no collateral. Two customers, Beijing Etechwin and Continental Automotive, accounted for 12% and 11% of total revenue in 2018, respectively. Two customers accounted for 10% or more of total accounts receivable at December 31, 2018; CRRC-SRI and Wuxi Chirun Technology accounted for 12% and 10% of accounts receivable, respectively. Three customers, Continental Automotive, Beijing Etechwin and CRRC-SRI, accounted for 15%, 11% and 10% of total revenue in 2017, respectively. Two customers accounted for 10% or more of total accounts receivable at December 31, 2017; Continental Automotive and CRRC-SRI accounted for 15% and 11% of accounts receivable, respectively.

Research and Development Expense

Research and development expenditures are expensed in the period incurred. Third-party funding of research and development expense under cost-sharing arrangements is recorded as an offset to research and development expense in the period the expenses are incurred. Research and development expense was $20.0 million and $16.3 million, net of third-party funding under cost-sharing arrangements of $0.2 million and $2.5 million, for the years ended December 31, 2018 and 2017, respectively. For the year ended December 31, 2017, third-party funding under cost-sharing arrangements included $2.2 million related to a joint development agreement to fund the short-term costs of developing technologies for the automotive market.

Shipping and Handling Expense

The Company recognizes shipping and handling expenses as a component of cost of revenue.

Advertising Expense

Advertising costs are expensed in the period incurred. Advertising expense was $0.3 million and $0.4 million for the years ended December 31, 2018 and 2017, respectively.

Foreign Currencies

The Company’s primary foreign currency exposure is related to its subsidiary in Korea. The functional currency of the Korean subsidiary is the Korean Won. The Company’s Korean subsidiary has U.S. dollar, Euro and local currency (Korean Won) revenue and operating expenses. Changes in these currency exchange rates impact the reported U.S. dollar amount of revenue, expenses and debt. Assets and liabilities of the Korean subsidiary are translated at month-end exchange rates, and revenue, expenses, gains and losses are translated at rates of exchange that approximate the rate in effect at the time of the transaction. Any translation adjustments resulting from this process are presented separately as a component of accumulated other comprehensive income within stockholders’ equity in the consolidated balance sheets. Foreign currency transaction gains and losses on intercompany balances considered long term in nature are accounted for as translation adjustments within equity. Accumulated other comprehensive income is recognized in the statement of operations when the related business is divested. All other foreign currency transaction gains and losses are reported in “foreign currency exchange loss, net” in the consolidated statements of operations.

Business Combinations

The Company accounts for businesses it acquires in accordance with ASC Topic 805, Business Combinations, which allocates the fair value of the purchase consideration to the tangible and intangible assets acquired and liabilities assumed based on their estimated fair values. The excess of the purchase consideration over the fair values of these identifiable assets and liabilities is recorded as goodwill. When determining the fair values of assets acquired and liabilities assumed, management makes significant estimates and assumptions. The Company may utilize third-party valuation specialists to assist the Company in the allocation. Initial purchase price allocations are subject to revision within the measurement period, not to exceed one year from the date of acquisition. Acquisition-related expenses and transaction costs associated with business combinations are expensed as incurred.

Restructuring and Exit Costs

Restructuring and exit costs involve employee-related termination costs, facility exit costs and other costs associated with restructuring activities. The Company accounts for charges resulting from operational restructuring actions in accordance with ASC Topic 420, Exit or Disposal Cost Obligations (“ASC 420”) and ASC Topic 712, Compensation-Nonretirement Postemployment Benefits (“ASC 712”).

The recognition of restructuring costs requires the Company to make certain assumptions related to the amounts of employee severance benefits, the time period over which leased facilities will remain vacant and expected sublease terms and discount rates. Estimates and assumptions are based on the best information available at the time the obligation arises. These estimates are reviewed and revised as facts and circumstances dictate; changes in these estimates could have a material effect on the amount accrued in the consolidated balance sheet.

Related Party Transactions

As part of the Nesscap Acquisition, Titan Power Solution LLS (“Titan”) became a customer of the Company. In May 2018, I2BF Global Ventures (“I2BF), of which a member of our board of directors is a founding partner and current director, obtained a controlling interest in Titan. During the year ended December 31, 2018, we received payments of approximately $397,000 from Titan related to the purchase of the Company’s products, of which payments of $282,000 were received by us after I2BF became a controlling owner of Titan in May 2018.

Net Income or Loss per Share

In accordance with the Earnings Per Share Topic of the FASB ASC, basic net income or loss per share is calculated using the weighted average number of common shares outstanding during the period. Diluted net income per share includes the impact of additional common shares that would have been outstanding if potentially dilutive common shares were issued. Potentially dilutive securities are not considered in the calculation of diluted net loss per share, as their inclusion would be anti-dilutive.

The following table sets forth the computation of basic and diluted net loss per share (in thousands, except per share data):



	Years Ended December 31,
	2018			2017
Numerator:
Loss from continuing operations, net of income taxes	$	(44,442	)	$	(53,862	)
Income from discontinued operations, net of income taxes	7,894			10,733
Net loss	$	(36,548	)	$	(43,129	)
Denominator:
Weighted average common shares outstanding, basic and diluted	41,031			35,480
Net income (loss) per share - basic and diluted:
Continuing operations	$	(1.08	)	$	(1.52	)
Discontinued operations	0.19			0.30
Net loss per share - basic and diluted	$	(0.89	)	$	(1.22	)

The following table summarizes instruments that may be convertible into common shares that are not included in the denominator used in the computation of diluted earnings per share because they are anti-dilutive for continuing operations, and as such the treatment for discontinued operations is also anti-dilutive (in thousands of shares):

Outstanding options to purchase common stock	357	361
Unvested restricted stock awards	—	26
Unvested restricted stock unit awards	2,757	2,650
Employee stock purchase plan awards	122	38
Bonus and director fees to be paid in stock awards	734	477
Convertible senior notes	7,245	7,245
	11,215	10,797

Stock-Based Compensation

The Company issues stock-based compensation awards to its employees and non-employee directors, including stock options, restricted stock, restricted stock units, and shares under an employee stock purchase plan. The Company records compensation expense for stock-based awards in accordance with the criteria set forth in the Stock Compensation Subtopic of the FASB ASC. The Company uses the Black-Scholes option pricing model to estimate the fair value of stock option grants. The determination of the fair value of stock options utilizing the Black-Scholes model is affected by the Company’s stock price and a number of assumptions, including expected volatility, expected term, risk-free interest rate and expected dividends.

The fair value of restricted stock awards (“RSAs”) and restricted stock unit awards (“RSUs”) with service-based or performance-based vesting is based on the closing market price of the Company’s common stock on the date of grant. Compensation expense equal to the fair value of each RSA or RSU is recognized ratably over the requisite service period. For RSUs with vesting contingent on Company performance conditions, the Company uses the requisite service period that is most likely to occur. The requisite service period is estimated based on the performance period as well as any time-based service requirements. If it is unlikely that a performance condition will be achieved, no compensation expense is recognized unless it is later determined that achievement of the performance condition is likely. Expense may be adjusted for changes in the expected outcomes of the related performance conditions, with the impact of such changes recognized as a cumulative adjustment in the consolidated statement of operations in the period in which the expectation changes.

The Company issues market-condition RSUs to certain members of executive management. Since the vesting of the market-condition RSUs is dependent on stock price performance, the fair values of these awards are estimated using a Monte-Carlo valuation model. The determination of the fair value of market-condition RSUs utilizing a Monte-Carlo valuation model is affected by the Company’s stock price and a number of assumptions, including expected volatility, expected life, risk-free interest rate and expected dividends.

In 2016, Company adopted a bonus plan that enabled participants to earn annual incentive bonuses based upon achievement of specified financial and strategic performance objectives. Under the terms of this plan, the Company has the ability to settle bonuses earned under the plan with common stock or fully vested RSUs. The Company settled the majority of bonuses earned under in 2017 in stock during 2018. For the fiscal year 2018 performance period, the Company intends to settle the amounts earned under the bonus plan in stock or fully vested RSUs in the first quarter of 2019. The stock-based compensation expense accrued under this bonus plan represents stock-settled debt per ASC 718 and ASC 480, as such, the Company has recorded a liability for bonuses expected to be paid in fully vested RSUs in “accrued employee compensation” in the Company’s consolidated balance sheets.

Stock-based compensation expense recognized in the consolidated statements of operations is based on equity awards ultimately expected to vest. The Company estimates forfeitures at the time of grant and revises forfeitures, if necessary, in subsequent periods with a cumulative catch up adjustment if actual forfeitures differ from those estimates. For market-condition awards, because the effect of the market-condition is reflected as an adjustment to the awards’ fair value at grant date, subsequent forfeitures due to the Company’s stock price performance do not result in a reversal of expense.

Recent Accounting Pronouncements

In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2014-09, Revenue from Contracts with Customers. ASU 2014-09 and its related amendments provide companies with a single model for accounting for revenue arising from contracts with customers and supersedes prior revenue recognition guidance, including industry-specific revenue guidance. The core principle of the model is to recognize revenue when control of the goods or services transfers to the customer, as opposed to recognizing revenue when the risks and rewards transfer to the customer under the existing revenue guidance. The guidance permits companies to either apply the requirements retrospectively to all prior periods presented, or apply the requirements in the year of adoption, through a cumulative adjustment. The Company adopted the new accounting standard using the modified retrospective transition method effective January 1, 2018 and recorded a $0.3 million impact to “accumulated deficit” in the Company’s consolidated balance sheet. See Note 2 for further information.

In February 2016, the FASB issued ASU No. 2016-02, Leases. The standard requires that a lessee recognize the assets and liabilities that arise from operating leases. A lessee should recognize in its balance sheet a liability to make lease payments (the lease liability) and a right-of-use asset representing its right to use the underlying asset for the lease term. For leases with a term of 12 months or less, a lessee is permitted to make an accounting policy election by class of underlying asset not to recognize lease assets and lease liabilities. In transition, lessees and lessors were originally required to recognize and measure leases at the beginning of the earliest period presented using a modified retrospective approach. In July 2018, FASB issued ASU No. 2018-11, Targeted Improvements. This update still requires modified retrospective transition; however, it adds the option to initially apply the new standard at the adoption date and recognize a cumulative-effect adjustment in the current period instead of at the beginning of the earliest period presented. The guidance is effective for annual and interim reporting periods beginning after December 15, 2018. The Company is in the process of finalizing its evaluation of current leases and quantifying the impact to its balance sheet. The Company expects that the adoption of the standard will have a material impact on its consolidated balance sheet for the recognition of certain operating leases as right-of-use assets and lease liabilities. The Company does not expect the adoption of this standard to have a material impact on its consolidated statements of operations. The Company will adopt the new accounting standard using the modified retrospective transition option effective January 1, 2019.

In March 2017, the FASB issued ASU No. 2017-07, Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost, which changes how employers that sponsor defined benefit pension or other postretirement benefit plans present the net periodic benefit cost in the statement of operations. The new guidance requires entities to report the service cost component in the same line item or items as other compensation costs. The other components of net benefit cost are required to be presented in the statement of operations separately from the service cost component and outside the subtotal of loss from operations. ASU 2017-07 also provides that only the service cost component is eligible for capitalization. This standard impacts the Company’s gross profit and loss from operations but has no impact on net loss or net loss per share. The Company adopted ASU 2017-07 on January 1, 2018, with adoption applied on a retrospective basis. The Company used the practical expedient that permits it to use the amounts previously disclosed in the defined benefit plans note for the prior comparative periods as the basis for applying the retrospective presentation requirements. In connection with this adoption, for the year ended December 31, 2017, the Company reclassified $39,000, $8,000 and $8,000 (excluding discontinued operations) of net non-service costs and income from cost of revenue, selling, general and administrative expense and research and development expense, respectively, to “other components of defined benefit plans, net”.

In February 2018, the FASB issued ASU No. 2018-02, Income Statement-Reporting Comprehensive Income, which amends the previous guidance to allow for certain tax effects “stranded” in accumulated other comprehensive income, which are impacted by the Tax Cuts and Jobs Act, to be reclassified from accumulated other comprehensive income into retained earnings. This amendment pertains only to those items impacted by the new tax law and will not apply to any future tax effects stranded in accumulated other comprehensive income. This standard is effective for the Company in the first quarter of 2019, with early adoption permitted. The Company does not expect this ASU to have a material impact on its consolidated financial statements.

In March 2018, the FASB issued ASU No. 2018-05, Income Taxes: Amendments to SEC paragraphs pursuant to SEC Staff Accounting Bulletin No. 118. The Amendments in this update add various SEC paragraphs pursuant to the issuance of SEC Staff Accounting Bulletin No. 118, Income Tax Accounting Implications of the Tax Cuts and Jobs Act (“SAB 118”). SAB 118 directs taxpayers to consider the implications of the Tax Cuts and Jobs Act as provisional when it does not have the necessary information available, prepared, or analyzed in reasonable detail to complete its accounting for the change in the tax law. The Company recognized the provisional tax impacts of the Tax Cuts and Jobs Act in the fourth quarter of 2017, therefore, the Company’s subsequent adoption of ASU 2018-05 in the first quarter of 2018 had no impact on its accounting for income taxes. During the fourth quarter of 2018, the Company’s accounting for this change in tax law was considered complete and no longer provisional.

In June 2018, the FASB issued ASU No. 2018-07, Improvements to Nonemployee Share-Based Payment Accounting, which simplifies the accounting for nonemployee share-based payments by aligning the accounting with the requirements for employee share-based compensation. This standard is effective for the Company in the first quarter of 2019, with early adoption permitted. The Company does not expect this ASU to have a material impact on its consolidated financial statements.

In August 2018, the FASB issued ASU No. 2018-13, Changes to the Disclosure Requirements for Fair Value Measurement. This ASU eliminates, adds and modifies certain disclosure requirements for fair value measurements as part of its disclosure framework project. The standard is effective for all entities for financial statements issued for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years. Early adoption is permitted. The adoption of this guidance is not expected to have a material impact on the Company’s financial statements.

In August 2018, the FASB issued ASU No. 2018-14, Compensation - Retirement Benefits - Defined Benefit Plans - General. This ASU modifies the disclosure requirements for defined benefit and other postretirement plans. This ASU eliminates certain disclosures associated with accumulated other comprehensive income, plan assets, related parties, and the effects of interest rate basis point changes on assumed health care costs; while other disclosures have been added to address significant gains and losses related to changes in benefit obligations. This ASU also clarifies disclosure requirements for projected benefit and accumulated benefit obligations. The amendments in this ASU are effective for fiscal years ending after December 15, 2020 and for interim periods therein with early adoption permitted. Adoption on a retrospective basis for all periods presented is required. The Company is currently evaluating the impact of adoption on its financial statement disclosures.

Business Enterprise Information

The Company operates as a single operating segment with a single product line. According to the FASB ASC Topic Disclosures about Segments of an Enterprise and Related Information, operating segments are defined as components of an enterprise for which separate financial information is evaluated regularly by the chief operating decision maker (“CODM”) in deciding how to allocate resources and in assessing performance. The Company’s CODM is the Chief Executive Officer who evaluates the Company’s financial information and resources and assesses performance on a consolidated basis.
