NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

1. Organization and description of business

Altair Engineering Inc. (“Altair” or the “Company”) is incorporated in the state of Delaware. The Company is a global technology company providing software and cloud solutions in the areas of product development, high performance computing and data analytics. Altair enables organizations across broad industry segments to compete more effectively in a connected world while creating a more sustainable future. The Company is headquartered in Troy, Michigan.

Basis of presentation

The accompanying unaudited consolidated financial statements have been prepared in accordance with United States generally accepted accounting principles (“GAAP”) and applicable rules and regulations of the Securities and Exchange Commission (“SEC”) regarding interim financial information.  Accordingly, the accompanying statements do not include all the information and notes required by GAAP for complete financial statements. The accompanying unaudited consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements (and notes thereto) for the year ended December 31, 2019, included in the most recent Annual Report on Form 10-K filed with the SEC. In the opinion of management, all adjustments considered necessary for a fair presentation of the financial statements have been included, and all adjustments are of a normal and recurring nature. The preparation of the financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, and disclosures of contingent assets and liabilities at the date of the financial statements and reported amounts of revenue and expenses during the reporting periods. Considerable judgment is often involved in making these determinations; use of different assumptions could result in significantly different results. Management believes its assumptions and estimates are reasonable and appropriate. However, actual results may differ from those estimates.  In addition, the results of operations for the three and six months ended June 30, 2020, are not necessarily indicative of the results that may be expected for any future period.

Use of estimates

The preparation of the consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and reported amounts of revenue and expenses during the reporting periods. On an ongoing basis, management evaluates its significant estimates including the stand alone selling price, or SSP, for each distinct performance obligation included in customer contracts with multiple performance obligations, valuation of acquired intangible assets in business combinations, the incremental borrowing rate used in the valuation of lease liabilities, the determination of the period of benefit for capitalized costs to obtain a contract, fair value of convertible senior notes, provision for credit loss, tax valuation allowances, liabilities for uncertain tax provisions, impairment of goodwill and intangible assets, retirement obligations, useful lives of intangible assets, revenue for fixed price contracts, and stock-based compensation. Actual results could differ from those estimates.

COVID-19

In March 2020, The World Health Organization declared the outbreak of COVID-19 a pandemic, and a public health emergency of international concern. The global spread of COVID-19 created significant volatility and uncertainty. Such conditions are expected to continue to persist. To limit the spread of COVID-19, governments have taken various actions from time to time including the issuance of travel restrictions, complete or partial prohibitions of non-essential activities, restrictions or shutdowns of non-essential businesses, stay-at-home orders and social distancing guidelines. Some of these actions have varied from initial responses, pivoting between full or complete to partial or limited restrictions depending upon local or regional conditions. Accordingly, many businesses have adjusted to these actions by reducing or suspending operating or other activities. This has negatively impacted several of the markets the Company serves, including the automotive and aerospace markets.

The Company continues to robustly engage with its customers, primarily virtually. While the Company believes this active level of engagement may mitigate potential and evolving negative impacts from COVID-19, existing and potential customers may choose to reduce or delay technology spending in response to COVID-19, or attempt to renegotiate contracts and obtain concessions, which may materially and negatively impact the Company’s operating results, financial condition and new business. In certain cases, the Company has provided longer than normal payment terms to certain of its customers; however, the terms are less than one year, and the Company does not expect this to materially affect its consolidated financial statements. COVID-19’s

9

impact on some of the Company’s customers has primarily contributed to the decrease in revenue for software related and client engineering services. The Company’s software product revenue has been affected by elongated sales cycles for some of its customers along with greater challenges in securing new and expansion business. The Company is unable to accurately predict the full impact that COVID-19 will have due to numerous uncertainties, including the full scope of the disease, the duration of the initial outbreak or the number and intensity of subsequent waves of infections, actions that may be taken by governmental authorities, the impact to the businesses of the Company’s customers and partners, and the development of treatments and vaccines. Even after the COVID-19 pandemic has subsided, the Company may experience material adverse impacts to its business as a result of any economic recession or depression that has occurred or may occur in the future. The Company will continue to evaluate the nature and extent of the impact to its business, consolidated results of operations, and financial condition.

Cash, cash equivalents and restricted cash

The Company considers all highly liquid investments with original or remaining maturities of 90 days or less at the date of purchase to be cash equivalents. Cash and cash equivalents are recorded at cost, which approximates fair value. Restricted cash is included in other long-term assets on the consolidated balance sheets. The following table provides a reconciliation of cash, cash equivalents and restricted cash reported in the consolidated balance sheets that sum to the total of the amounts reported in the consolidated statement of cash flows (in thousands):

	June 30, 2020		December 31, 2019
Cash and cash equivalents	$	250,540	$	223,117
Restricted cash included in other long-term assets		386		380
Total cash, cash equivalents, and restricted cash	$	250,926	$	223,497

Restricted cash represents amounts required for a contractual agreement with an insurer for the payment of potential health insurance claims, and term deposits for bank guarantees.

Inventory

Inventory consists of finished goods and is stated at the lower of cost and net realizable value. Cost is determined using the first-in, first-out method. Net realizable value is the estimated selling prices in the ordinary course of business, less reasonable predictable costs of completion, disposal and transportation. The valuation of inventory requires management to estimate excess inventory as well as inventory that is not of saleable quality. The determination of obsolete or excess inventory requires management to estimate market conditions and future demand for the Company’s products. Inventory was $2.8 million and $2.4 million at June 30, 2020 and December 31, 2019, respectively, and is included in prepaid expenses and other current assets in the consolidated balance sheets.

Receivable for French R&D credit

The French government provides a research and development (“R&D”) tax credit known as Credit Impôt Recherche, or CIR, in order to encourage Companies to invest in R&D activities. The tax credit is deductible from French income tax and any excess is carried forward three years. After three years, any unused credit may be reimbursed to the Company by the French government. As of June 30, 2020, the Company had approximately $13.7 million of receivables from the French government related to CIR, of which $2.5 million was recorded in income tax receivable and the remaining $11.2 million was recorded in other long-term assets. As of December 31, 2019, the Company had approximately $12.1 million of receivables from the French government related to CIR, of which $2.5 million was recorded in income tax receivable and the remaining $9.6 million was recorded in other long-term assets. CIR is subject to customary audit by French tax authorities.

Mezzanine equity

In 2017, the Company issued 200,000 shares of Class A common stock to a third party as partial consideration for the purchase of developed technology. These shares have a put right that can be exercised by the holder five years from date of purchase at $12.50 per share that requires the shares to be recorded at fair value at the issuance date and classified as mezzanine equity in the consolidated balance sheet. The put right option is terminated if the shareholders sell their shares. As of December 31, 2017, the Company concluded that it is no longer probable that the put option will be exercised as the put value is substantially below market value and subsequent adjustment is not required.

During the quarter ended June 30, 2020, the third party holder sold 133,336 shares on the open market and as a result, the issuance value of those shares was reclassified into permanent equity out of mezzanine equity. The remaining 66,664 shares shall remain as mezzanine equity until one of the following three events take place: (1) the shares are sold on the open market; (2) a redemption feature lapses; or (3) there is a modification of the terms of the instrument.

Leases

The Company determines if an arrangement is a lease at inception. Operating leases are included in operating lease right-of-use (“ROU”) assets, current portion of operating lease liabilities, and operating lease liabilities, net of current portion on the Company’s consolidated balance sheets. Finance leases are included in property and equipment, current portion of long-term debt, and long-term debt, net of current portion on the consolidated balance sheets. The Company did not receive any lease concessions related to COVID-19 that had a material effect on the Company’s consolidated financial statements.

2. Recent accounting guidance

Accounting standards adopted

Credit Losses – In June 2016, the FASB issued ASU 2016-13, Financial Instruments — Credit Losses (Topic 326):  Measurement of Credit Losses on Financial Instruments. The ASU significantly changes how entities will measure credit losses on most financial assets. The Company adopted ASU 2016-13 effective January 1, 2020 and recorded a cumulative effect adjustment to retained earnings of $0.4 million related to the adoption of ASU 2016-13; prior periods have not been adjusted. Under this new accounting standard, beginning January 1, 2020, an allowance for expected credit losses for groups of billed and unbilled receivables and contract assets that share similar risk characteristics is recorded based on an evaluation of historical loss experience, current conditions, and reasonable and supportable forecasts. Accounts are written off when it becomes apparent that such amounts will not be collected, generally when amounts are past due by greater than one year. Generally, the Company does not require collateral or charge interest on accounts receivable. Accounts receivable were reported net of an allowance for doubtful accounts of $2.4 million and $1.4 million at June 30, 2020 and December 31, 2019, respectively. 

Subsequent to adoption, the Company considered the impact of COVID-19 on its historical credit loss rates and made an adjustment to increase expected credit loss rates. The impact resulting from the increased credit loss rates did not have a material effect on the Company’s consolidated financial statements.

Fair Value – In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework – Changes to the Disclosure Requirements for Fair Value Measurement. This ASU modifies the disclosure requirements for fair value measurements, by removing, modifying, or adding certain disclosures. The Company adopted ASU 2018-13 on January 1, 2020. The adoption of this guidance did not have a material effect on the Company’s consolidated financial statements.

11

Intangibles – In August 2018, the FASB issued ASU 2018-15, Intangibles – Goodwill and Other – Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That is a Service Contract. This ASU clarifies and aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software. The Company adopted ASU 2018-15 on January 1, 2020, on a prospective basis. The adoption of this guidance did not have a material effect on the Company’s consolidated financial statements.

Accounting standards not yet adopted 

Retirement Benefits – In August 2018, the FASB issued ASU 2018-14, Compensation – Retirement Benefits- Defined Benefit Plans – General (Subtopic 715-20): Disclosure Framework – Changes to the Disclosure Requirements for Defined Benefit Plans. This ASU modifies the disclosure requirements for defined benefit pension or other postretirement plans. The amendments are effective for fiscal years ending after December 15, 2020; early adoption is permitted. The Company is currently evaluating the impact of the new guidance on its consolidated financial statements and related disclosures and does not expect this guidance to have a material effect on its consolidated financial statements.

Income Taxes – In December 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes. This ASU simplifies the accounting for income taxes by removing certain exceptions to the general principles in Topic 740 and improves consistent application of GAAP for other areas of Topic 740 by clarifying and amending existing guidance. The amendments are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2020; early adoption is permitted. The Company is currently evaluating the impact of the new guidance on its consolidated financial statements and related disclosures and does not expect this guidance to have a material effect on its consolidated financial statements.

Reference Rate Reform – In March 2020, the FASB issued ASU 2020-04. Reference Rate Reform (Topic 848) - Facilitation of the Effects of Reference Rate Reform on Financial Reporting. This ASU provides optional expedients and exceptions for applying U.S. GAAP to contract modifications and hedging relationships, subject to meeting certain criteria, that reference LIBOR or another rate that is expected to be discontinued. The amendments in the guidance are effective for all entities as of March 12, 2020 through December 31, 2022. The Company is currently evaluating the impact of this new guidance on its consolidated financial statements and related disclosures and does not expect this guidance to have a material effect on its consolidated financial statements.

3. Revenue from contracts with customers

Revenue recognition

Software revenue

Revenue is derived principally from the licensing of software products and from related maintenance contracts. The Company enters into contracts that include combinations of products, maintenance and services, which are accounted for as separate performance obligations with differing revenue recognition patterns.

Revenue from term-based software licenses is classified as software revenue. Term-based licenses are sold only as a bundled arrangement that includes the rights to a term-based software license and post-contract customer support (PCS), which includes unspecified technical enhancements and customer support. Maximizing the use of observable inputs, the Company determined that a majority of the estimated standalone selling prices of the term-based license is attributable to the term-based license and a minority is attributable to the PCS. The license component is classified as license revenue and recognized as revenue upon the later of delivery of the licensed product or the beginning of the license period. PCS is classified as maintenance and other services and is recognized ratably over the term of the contract, as the Company provides the PCS benefit over time as a stand ready to perform obligation.

In addition to term-based software licenses, the Company sells perpetual licenses. Software revenue is recognized upon the later of delivery of the licensed product or the beginning of the license period. Typically, the Company’s perpetual licenses are sold with PCS. The Company allocates value in bundled perpetual and PCS arrangements based on the value relationship between the software license and maintenance. Revenue from PCS is classified as maintenance and other services and is recognized ratably over the term of the contract, as the Company satisfies the PCS performance obligation over time as a stand ready to perform obligation.

12

Revenue from training, consulting and other services is recognized as the services are performed, and is classified as maintenance and other services in the consolidated statement of operations. For contracts in which the service consists of a single performance obligation, such as providing a training class to a customer, the Company recognizes revenue upon completion of the performance obligation. For service contracts that are longer in duration and often include multiple performance obligations (for example, point-in-time training and consulting), the Company measures the progress toward completion of the obligations and recognizes revenue accordingly. In measuring progress towards the completion of performance obligations, the Company typically utilizes output-based estimates for services with fixed fee arrangements, and estimates output based on the total tasks completed as compared to the total tasks required for each contract. Input-based estimates are utilized for services that involve general consultations with contractual billing arrangements based on time and materials, utilizing direct labor as the input measure.

The Company also executes arrangements through indirect channel partners in which the channel partners are authorized to market and distribute the Company's software products to end users of the Company's products and services in specified territories. In sales facilitated by channel partners, the channel partner bears the risk of collection from the end-user customer. The Company recognizes revenue from transactions with channel partners when the channel partner submits a purchase commitment, collectability from the channel partner is probable, and the performance obligation is met, at a point in time or over time as appropriate, provided that all other revenue recognition criteria are satisfied. Revenue from channel partner transactions is the amount remitted to the Company by the channel partners. This amount includes a fee for PCS that is compensation for providing technical enhancements and the second level of technical support to the end user, which is recognized over the period that PCS is to be provided. The Company does not offer right of return, product rotation, or price protection to any of its channel partners.

Non-income related taxes collected from customers and remitted to governmental authorities are recorded on the consolidated balance sheets as accounts receivable, net and other accrued expenses and current liabilities. These amounts are reported on a net basis in the consolidated statements of operations and do not impact reported revenues or expenses. Certain hardware revenue is included within software revenue and is recognized when all revenue recognition criteria stated above are met, which is generally when the products are delivered to end customers.

Significant judgments

Software revenue

The Company’s contracts with customers typically include promises to transfer licenses and services to a customer. Judgment is required to determine if the promises are separate performance obligations within the context of the arrangement, and if so, the allocation of the transaction price to each performance obligation. The Company’s determination of standalone selling price for performance obligations is based on the midpoint of the range of historical observable prices for goods and services sold separately. In addition, the Company estimates the standalone selling price for certain performance obligations where observable prices are not directly available or a significant portion of historical prices are not within the range. In instances where standalone selling price was not determined based on the range of historical observable prices for goods and services sold separately, the Company used an adjusted market assessment approach to estimate the standalone selling price. In such cases the Company has considered market conditions and other observable inputs, such as internal price lists, peer data, and industry data for a similar or identical product. The Company estimates standalone selling price at contract inception considering all information that is reasonably available and is based on the amount of consideration for which the Company expects to be entitled in exchange for transferring the promised good or service to the customer. The corresponding revenues are recognized as the related performance obligations are satisfied.

The Company’s contracts do not include a significant financing component requiring adjustment to the transaction price. Payment terms vary by contract type; however, arrangements typically stipulate a requirement for the customer to pay within 30 days.

The Company rarely enters into agreements to modify previously executed contracts, which constitute contract modifications. The Company assesses each of these contract modifications to determine (i) if the additional products and services are distinct from the products and services in the original arrangement; and (ii) if the amount of consideration expected for the added products and services reflects the stand-alone selling price of those products and services, as adjusted for contract-specific circumstances. A contract modification meeting both criteria is accounted for as a separate contract. A contract modification not meeting both criteria is considered a change to the original contract and is accounted for on either (i) a prospective basis as a termination of the existing contract and the creation of a new contract; or (ii) a cumulative catch-up basis. Generally, the Company’s contract modifications meet both criteria and are accounted for as a separate contract, as adjusted for contract-specific circumstances.

13

Software related services revenue

Consulting services from product design and development projects are considered distinct performance obligations and are provided to customers on a time-and-materials (“T&M”) or fixed-price basis. Altair recognizes software services revenue for T&M contracts based upon hours worked and contractually agreed upon hourly rates using the input method. Revenue from fixed-price engagements is recognized using the output method based on the ratio of costs incurred, to the total estimated project costs.

Client engineering services and Other revenue

Client engineering services revenue are derived from professional services for staffing primarily representing engineers and data scientists located at a customer site. These professional services are considered distinct performance obligations and are provided to customers on a T&M basis. The Company recognizes this revenue for T&M contracts based upon hours worked and contractually agreed upon hourly rates using the input method. No significant judgments were made for revenue recognition within Other revenue.

Disaggregation of revenue

The Company disaggregates its software revenue by type of performance obligation and timing of revenue recognition as follows (in thousands):

	Three Months Ended June 30,				Six Months Ended June 30,
	2020		2019		2020		2019
Software revenue:
Term licenses	$	43,260	$	45,974	$	112,641	$	111,031
Perpetual licenses		7,758		10,679		15,920		22,243
Maintenance		28,885		25,333		57,093		48,085
Professional services and other		1,930		2,422		4,622		6,340
Total software revenue	$	81,833	$	84,408	$	190,276	$	187,699

The Company derived approximately 10% of its total revenue through indirect sales channels for the six months ended June 30, 2020 and 2019.

Software related services revenue, client engineering services revenue, and other revenue were categorized based on the nature and timing of revenue and cash flows.

Costs to obtain a contract

The Company pays commissions for new software product and PCS sales as well as for renewals of existing software and PCS contracts. Commissions paid to obtain renewal contracts are not commensurate with the commissions paid for new product sales and therefore, a portion of the commissions paid for new contracts relate to future renewals.

The Company accounts for new product sales commissions using a portfolio approach and allocates the cost of commissions in proportion to the allocation of transaction price of license and PCS performance obligations. Commissions allocated to the license and license renewal components are expensed at the time the license revenue is recognized. Commissions allocated to PCS are capitalized and amortized on a straight-line basis over a period of four years, reflecting the Company’s estimate of the expected period that it will benefit from those commissions. As of June 30, 2020, and December 31, 2019, capitalized costs to obtain a contract were $3.0 million and $2.3 million, respectively, recorded in prepaid and other current assets, and $0.8 million and $0.8 million, respectively, recorded in other long-term assets. Amortization expense was $1.0 million and $1.6 million for the three and six months ended June 30, 2020, respectively, and $1.2 million and $2.2 million for the three and six months ended June 30, 2019, respectively. Amortization expense was included in sales and marketing expense in the Company’s consolidated statement of operations.

14

Contract assets

At June 30, 2020 and December 31, 2019, contract assets were $5.6 million and $4.5 million, respectively, recorded in accounts receivable, and $2.3 million and $2.7 million, respectively, recorded in prepaid expenses and other current assets.

Deferred revenue

Deferred revenue consists of billings made or payments received in advance of revenue recognition from software license, PCS and professional services agreements. The timing of revenue recognition may differ from the timing of billings to customers. Payment terms vary by the type and location of customer and the products or services offered. The term between invoicing and when payment is due is not significant. The Company generally invoices its customers annually for the forthcoming year of software licenses, and more frequently for other products and services. Accordingly, the Company’s deferred revenue balance does not include revenue for future years of multiple year non-cancellable contracts that have not yet been billed.

Approximately $53.7 million of revenue recognized during the six months ended June 30, 2020, was included in the deferred revenue balances at the beginning of the year. Revenue allocated to remaining performance obligations represents contracted revenue that has not yet been recognized, which includes deferred revenue and amounts that will be invoiced and recognized as revenue in future periods. Contracted revenue not yet recognized was $117.9 million as of June 30, 2020, of which the Company expects to recognize approximately 82% of the revenue over the next 12 months and the remainder thereafter.

The Company continues to monitor the significant global economic uncertainty as a result of COVID-19 to assess the outlook for demand for its products and the impact on its business. Based on the Company’s interim impairment assessment, there were no indicators of impairment identified during the second quarter of 2020. Notwithstanding this conclusion, if business conditions were to deteriorate in a significant manner or for an extended duration, the likelihood of impairment would increase, and the Company would again assess whether events or changes in circumstances indicate that an asset impairment that is more likely than not exists. Specifically, certain non-amortizing intangible assets from recent acquisitions valued on the basis of short-term forecasts of revenue will be re-assessed for indicators of impairment and it is possible that an impairment charge will be reflected in the future should COVID-19 business conditions worsen or extend substantially in duration.

The allocation of fair value of purchase consideration of the Company’s 2019 acquisitions was finalized in the first quarter of 2020, and there were no material changes to the fair value of assets acquired and liabilities assumed, as previously reported.

Convertible senior notes

In June 2019, the Company issued $230.0 million aggregate principal amount of 0.25% convertible senior notes due in 2024 (the "Convertible Notes"), which includes the underwriters’ exercise in full of their option to purchase an additional $30.0 million principal amount of the Convertible Notes, in a public offering. The net proceeds from the issuance of the Convertible Notes were $221.9 million after deducting the underwriting discounts and commissions and estimated issuance costs.

The Company entered into a First Supplemental Indenture relating to the issuance by the Company of the Convertible Notes (the “Supplemental Indenture”) supplementing the Indenture, dated June 10, 2019 (the “Base Indenture,” and together with the Supplemental Indenture, the “Indenture”), by and between the Company and U.S. Bank National Association, as trustee (the “Trustee”). The Indenture includes customary covenants and sets forth certain events of default after which the Convertible Notes may be declared immediately due and payable and sets forth certain types of bankruptcy or insolvency events of default involving the Company after which the Convertible Notes become automatically due and payable. The Convertible Notes are senior unsecured obligations of the Company.

The Convertible Notes bear interest at a rate of 0.25% per year, payable semi-annually in arrears on June 1 and December 1 of each year, commencing December 1, 2019. The Convertible Notes will mature on June 1, 2024, unless, earlier repurchased or redeemed by the Company or converted pursuant to their terms.

The Convertible Notes have an initial conversion rate of 21.5049 shares of the Company's Class A common stock per $1,000 principal amount of Convertible Notes, which is equivalent to an initial conversion price of approximately $46.50 per share of its Class A common stock. The conversion rate will be subject to adjustment upon the occurrence of certain events specified in the Indenture but will not be adjusted for any accrued and unpaid interest. In addition, upon the occurrence of a make whole fundamental change or a redemption period (each as defined in the Indenture), the Company will, in certain circumstances, increase the conversion rate by a specified number of additional shares for a holder who elects to convert its Convertible Notes in connection with such make whole fundamental change or during the relevant redemption period.

Holders of the Convertible Notes may convert all or any portion of their Convertible Notes at any time prior to the close of business on December 1, 2023, in integral multiples of $1,000 principal amount, only under the following circumstances:

• During any calendar quarter commencing after the calendar quarter ending on September 30, 2019 (and only during such calendar quarter), if the last reported sale price of the Class A Common Stock for at least 20 trading days (whether or not consecutive) during a period of 30 consecutive trading days ending on, and including, the last trading day of the immediately preceding calendar quarter is greater than or equal to 130% of the conversion price on each applicable trading day;

• During the five business day period after any five consecutive trading day period (the “measurement period”) in which the trading price (as defined in the Indenture) per $1,000 principal amount of Convertible Notes for each trading day of the measurement period was less than 98% of the product of the last reported sale price of the Class A Common Stock and the conversion rate on each such trading day;

• If the Company calls any or all of the Convertible Notes for redemption (which the Company may not do prior to June 6, 2022), at any time prior to the close of business on the scheduled trading day immediately preceding the redemption date; or

17

• Upon the occurrence of specified corporate events.

On or after December 1, 2023 until the close of business on the business day immediately preceding the maturity date, holders may convert their Convertible Notes at any time, regardless of the foregoing circumstances. Upon conversion, the Company may satisfy its conversion obligation by paying and/or delivering, as the case may be, cash, shares of Class A Common Stock or a combination of cash and shares of the Class A Common Stock, at the Company’s election, in the manner and subject to the terms and conditions provided in the Indenture.

During the quarter ended June 30, 2020, the conditions allowing holders of the Convertible Notes to convert were not met. Therefore, the Convertible Notes were classified as long-term debt on the consolidated balance sheet as of June 30, 2020.

As of June 30, 2020, the “if converted value” did not exceed the principal amount of the Convertible Notes.

The Company accounts for the Convertible Notes as separate liability and equity components. The carrying amount of the liability component of the Convertible Notes was calculated by measuring the fair value of similar debt instruments that do not have an associated convertible feature. The carrying amount of the equity component representing the conversion option was determined by deducting the fair value of the liability component from the par value of the Convertible Notes. The difference between the principal amount of the Convertible Notes and the liability component, equal to $51.8 million (the “debt discount”), is amortized to interest expense over the term of the Convertible Notes using the effective interest method. The equity component is not remeasured as long as it continues to meet the conditions for equity classification.

The Company allocated issuance costs related to the issuance of the Convertible Notes to the liability and equity components using the same proportions as the initial carrying value of the Convertible Notes. Issuance costs attributable to the liability component are being amortized to interest expense using the effective interest method over the term of the Convertible Notes. Issuance costs attributable to the equity component are included with the equity component in stockholders’ equity.

The net carrying value of the liability component of the Convertible Notes was as follows (in thousands):

	June 30,		December 31,
	2020		2019
Principal	$	230,000	$	230,000
Less: unamortized debt discount		42,070		46,820
Less: unamortized debt issuance costs		5,105		5,686
Net carrying amount	$	182,825	$	177,494

The net carrying value of the equity component of the Convertible Notes was $50.0 million at both June 30, 2020 and December 31, 2019.

The interest expense recognized related to the Convertible Notes was as follows (in thousands):

	Three Months Ended June 30,				Six Months Ended June 30,

Credit agreement

Revolving credit facility

The Company has a $150.0 million credit facility with a maturity date of December 15, 2023 (“2019 Amended Credit Agreement”). The 2019 Amended Credit Agreement provides for an accordion feature that allows the Company to expand the size of the revolving line of credit by an additional $50.0 million, subject to certain conditions, by obtaining additional commitments from the existing lenders or by causing a person acceptable to the administrative agent to become a lender (in each case subject to the terms and conditions set forth in the 2019 Amended Credit Agreement).

18

As of June 30, 2020, the Company had no outstanding borrowings under the 2019 Amended Credit Agreement and there was $150.0 million available for future borrowing. The 2019 Amended Credit Agreement is available for general corporate purposes, including working capital, capital expenditures, and permitted acquisitions.

Borrowings under the 2019 Amended Credit Agreement bear interest at a rate per annum equal to an agreed upon applicable margin plus, at the Company’s option, either the Alternate Base Rate (defined as the greatest of (1) the Prime Rate (as defined in the 2019 Amended Credit Agreement) in effect on such day, (2) the Federal Funds Effective Rate (as defined in the 2019 Amended Credit Agreement) in effect on such day plus 1/2 of 1.00% or (3) the Adjusted LIBO Rate (as defined in the 2019 Amended Credit Agreement) for a one month interest period on such day (or if such day is not a business day, the immediately preceding business day) plus 1.00%) or the Adjusted LIBO Rate. The applicable margin for borrowings under the 2019 Amended Credit Agreement is based on the Company’s most recently tested consolidated total net leverage ratio and will vary from (a) in the case of Eurodollar loans, 1.25% to 2.00%, and (b) in the case of ABR loans and swingline loans, 0.25% to 1.00%. The Company pays a commitment fee (based on the Company’s most recently tested consolidated total senior secured net leverage ratio) ranging from 0.15% to 0.30% on the unused portion of the 2019 Amended Credit Agreement.

Collateral and guarantees

The 2019 Amended Credit Agreement is secured by collateral including (i) substantially all of the Company’s properties and assets, and the properties and assets of the Company’s direct and indirect domestic subsidiaries but excluding any patents, copyrights, patent applications or copyright applications or any trade secrets or software products and (ii) pledges of the equity interests in all present and future direct and indirect domestic subsidiaries (subject in each case to certain exceptions as provided for under the 2019 Amended Credit Agreement). The Company’s direct and indirect domestic subsidiaries are guarantors of all the obligations under the 2019 Amended Credit Agreement.

Debt covenants

The 2019 Amended Credit Agreement requires the Company to maintain the following financial covenants:

• Maximum Net Leverage Ratio: On the last day of each fiscal quarter, the Company on a consolidated basis will not permit the ratio of total indebtedness (net of unrestricted domestic cash in excess of $20.0 million) to EBITDA, as such terms are defined in the 2019 Amended Credit Agreement, for the rolling four quarter period ending on such date to be greater than 5.00 to 1.00 as of the last day of any such fiscal quarter.

• Senior Secured Leverage Ratio: On the last day of each fiscal quarter, the Company on a consolidated basis will not permit the ratio of total indebtedness secured by a lien (net of unrestricted domestic cash in excess of $20.0 million) to EBITDA, as such terms are defined in the 2019 Amended Credit Agreement, for the rolling four quarter period ending on such date to be greater than 3.00 to 1.00 as of the last day of any such fiscal quarter.

• Consolidated Interest Coverage Ratio: On the last day of each fiscal quarter, the Company on a consolidated basis will not permit the ratio of (x) EBITDA to (y) cash Consolidated Interest Expense, as such terms are defined in the 2019 Amended Credit Agreement, in each case for the rolling four quarter period ending on such date, to be less than 3.00 to 1.00 as of the last day of any such fiscal quarter.

At June 30, 2020, the Company was in compliance with all the above financial covenants.

8. Fair value measurements

The accounting guidance for fair value, among other things, defines fair value, establishes a consistent framework for measuring fair value and expands disclosure for each major asset and liability category measured at fair value on either a recurring or nonrecurring basis. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability (an exit price) in an orderly transaction between market participants at the reporting date. The framework for measuring fair value consists of a three-level valuation hierarchy that prioritizes the inputs to valuation techniques used to measure fair value based upon whether such inputs are observable or unobservable. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect market assumptions made by the reporting entity. The three-level hierarchy for the inputs to valuation techniques is briefly summarized as follows:

Level 1 – Quoted prices in active markets for identical assets and liabilities at the measurement date;

Level 2 – Observable inputs, other than the quoted prices in active markets, that are observable either directly or indirectly; and

Level 3 – Unobservable inputs in which there is little or no market data, which require the reporting entity to develop its own assumptions.

An asset’s or liability’s fair value measurement level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement. Valuation techniques used need to maximize the use of observable inputs and minimize the use of unobservable inputs.

The carrying value of cash and cash equivalents, accounts receivable and accounts payable approximate fair value due to their short maturities. Interest on the Company’s line of credit is at a variable rate, and as such the debt obligation outstanding approximates fair value.

The carrying value of the Company’s Convertible Notes are at face value less unamortized debt discount and issuance costs. The estimated fair values of the Convertible Notes, which the Company has classified as Level 2 financial instruments, were determined based on quoted bid prices of the Convertible Notes on the last trading day of each reporting period. At June 30, 2020, the fair value of the Convertible Notes was $242.5 million and is presented for required disclosure purposes only. For further information on the Convertible Notes, see Note 6. – Debt.

9. Net (loss) income per share

Basic (loss) income per share attributable to common stockholders is computed using the weighted average number of shares of common stock outstanding for the period, excluding stock options and restricted stock units (“RSUs”). Diluted (loss) income per share attributable to common stockholders is based upon the weighted average number of shares of common stock outstanding for the period and potentially dilutive common shares, including the effect of stock options and RSUs under the treasury stock method. The following table sets forth the computation of the numerators and denominators used in the basic and diluted (loss) income per share amounts (in thousands, except per share data):

	Three Months Ended June 30,						Six Months Ended June 30,
	2020			2019			2020			2019
Numerator:
Net (loss) income	$	(10,223	)	$	(3,120	)	$	(4,193	)	$	9,899
Denominator:
Denominator for basic (loss) income per share— weighted average shares		72,999			71,373			72,811			71,081
Effect of dilutive securities, stock options and RSUs		—			—			—			5,936
Denominator for dilutive (loss) income per share		72,999			71,373			72,811			77,017
Net (loss) income per share attributable to common   stockholders, basic	$	(0.14	)	$	(0.04	)	$	(0.06	)	$	0.14
Net (loss) income per share attributable to common   stockholders, diluted	$	(0.14	)	$	(0.04	)	$	(0.06	)	$	0.13

The computation of diluted (loss) income per share does not include shares that are anti-dilutive under the treasury stock method because their exercise prices are higher than the average fair value of the Company’s stock during the period or due to a net loss in the period. For each of the three and six months ended June 30, 2020, there were 4.5 million anti-dilutive stock options excluded from the computation of (loss) income per share. For the three months ended June 30, 2019, there were 5.6 million anti-dilutive stock options excluded from the computation of (loss) income per share. For the six months ended June 30, 2019, there were no anti-dilutive shares excluded from the computation of income per share.

The Company expects to settle the principal amount of the Convertible Notes in cash, and therefore, the Company uses the treasury stock method for calculating any potential dilutive effect of the Conversion Option on diluted net income per share, if applicable. The Conversion Option will have a dilutive impact on net income per share of common stock when the average market price of the Company’s Class A common stock for a given period exceeds the conversion price of the Convertible Notes of $46.50 per share. During the three and six months ended June 30, 2020, the Company's weighted average common stock price was below the conversion price of the Convertible Notes.

10. Stock-based compensation

2001 stock-based compensation plans

Nonqualified stock option plan

In 2001, the Company established the Nonqualified Stock Option Plan (“NSO Plan”) under which 3,246,119 stock options with an exercise price of $0.000025 remain outstanding at June 30, 2020. The NSO Plan was terminated in 2003. Stock options under the NSO plan were immediately vested and have a contractual term of 35 years from the date of grant. The outstanding awards will continue to be governed by their existing terms under the NSO Plan. The NSO Plan is accounted for as an equity plan.

The following table summarizes the stock option activity under the NSO Plan for the period:

	Number of options			Weighted average exercise price per share		Weighted average remaining contractual term (years)		Aggregate intrinsic value (in millions)
Outstanding at January 1, 2020		3,557,436		$	0.000025		17.0	$	127.8
Exercised		(311,317	)	$	0.000025
Forfeited		—			—
Outstanding and exercisable at June 30, 2020		3,246,119		$	0.000025		16.5	$	129.0

21

The total intrinsic value of the NSO Plan stock options exercised during the six months ended June 30, 2020, was $10.4 million.

Incentive and nonqualified stock-based plan

Also in 2001, the Company established the Incentive and Nonqualified Stock-based Plan (“ISO Plan”) which was terminated in 2011 and was authorized to issue nonqualified stock options (“NQSO”) and incentive stock options (“ISO”) covering 11,153,872 shares of Class A common stock. The NQSO grants could be issued at less than the fair market value at date of grant under the terms of the ISO Plan, while ISO grants were issued at a price equal to or greater than the fair market value at date of grant. Options generally vested over a two to three-year period. All options have a contractual term of ten years from the date of grant.

The following table summarizes the stock option activity under the 2001 stock-based compensation plans for the period:

	Number of options			Weighted average exercise price per share		Weighted average remaining contractual term (years)		Aggregate intrinsic value (in millions)
Outstanding at January 1, 2020		103,000		$	0.64		1.0	$	3.6
Exercised		(65,500	)	$	0.64
Forfeited		—			—
Outstanding and exercisable at June 30, 2020		37,500		$	0.64		0.5	$	1.5

The total intrinsic value of the ISO Plan stock options exercised during the six months ended June 30, 2020, was $1.9 million.

2012 stock-based compensation plans

During 2012, the Company established the 2012 Incentive and Nonqualified Stock Option Plan (“2012 Plan”) which permits the issuance of 5,200,000 shares of Class A common stock for the grant of nonqualified stock options and incentive stock options for management, other employees, and board members of the Company. The options are issued at a price equal to or greater than fair market value at date of grant. All options have a contractual term of 10 years from date of grant.

The 2012 Plan is accounted for as an equity plan. For those options expected to vest, compensation expense is recognized on a straight-line basis over a four-year period, the total requisite service period of the awards. Total compensation cost related to nonvested awards not yet recognized as of June 30, 2020, totaled $0.3 million, and is expected to be recognized over a weighted average period of 0.9 years.

The following table summarizes the stock option activity under the 2012 Plan for the period:

	Number of options			Weighted average exercise price per share		Weighted average remaining contractual term (years)		Aggregate intrinsic value (in millions)
Outstanding at January 1, 2020		1,183,817		$	4.23		6.1
Granted		—			—
Exercised		(116,968	)	$	3.79
Forfeited		(7,100	)	$	4.56
Outstanding at June 30, 2020		1,059,749		$	4.28		5.6
Exercisable at June 30, 2020		925,859		$	4.15		5.5	$	33.0

The total intrinsic value of the 2012 Plan stock options exercised during the six months ended June 30, 2020, was $3.9 million.

22

2017 stock-based compensation plan

In 2017, the Company’s board of directors adopted the 2017 Equity Incentive Plan (“2017 Plan”), which was approved by the Company’s stockholders. The 2017 Plan provides for the grant of incentive stock options to the Company’s employees and any parent and subsidiary corporations’ employees, and for the grant of nonstatutory stock options, stock appreciation rights, restricted stock, restricted stock units, performance units, performance shares, other cash-based awards and other stock-based awards to the Company’s employees, directors and consultants and the Company’s parent, subsidiary, and affiliate corporations’ employees and consultants. As of January 1, 2020, the 2017 Plan had 10,277,034 authorized shares of the Company’s Class A common stock reserved for issuance.

The following table summarizes the restricted stock units, or RSUs, awarded under the 2017 Plan for the period:

	Number of RSUs
Outstanding at January 1, 2020		781,301
Granted		565,723
Vested		(193,684	)
Forfeited		(16,313	)
Outstanding at June 30, 2020		1,137,027

The weighted average grant date fair value of the RSUs was $33.73 and the RSUs generally vest in four equal annual installments. Total compensation cost related to nonvested awards not yet recognized as of June 30, 2020, totaled $62.9 million, and is expected to be recognized over a weighted average period of approximately three years.

The following table summarizes the stock option activity under the 2017 Plan for the period:

	Number of options			Weighted average exercise price per share		Weighted average remaining contractual term (years)		Aggregate intrinsic value (in millions)
Outstanding at January 1, 2020		20,000		$	38.11		9.2
Granted		2,121,454		$	39.48
Exercised		—		$	—
Forfeited		(3,472	)	$	38.38
Outstanding at June 30, 2020		2,137,982		$	39.48		9.9
Exercisable at June 30, 2020		5,158		$	37.84		8.5	$	0.01

In addition to the stock options granted above, the Company expects to grant an additional 2.0 million stock options on December 2, 2020, with an exercise price reflecting the fair value on that date. Recipients of the December 2, 2020, deferred stock option award must be employed on that date in order to receive the grant. The Company has concluded that the grant date for this deferred award is December 2, 2020, and this grant will not be reflected in the table above until the fourth quarter of 2020.

The Company measures the fair value of its equity awards on the date of grant using the Black-Scholes option pricing model. This valuation model requires the Company to make certain estimates and assumptions, including assumptions related to the expected price volatility of the Company’s stock, the period under which the options will be outstanding, the rate of return on risk-free investments, and the expected dividend yield for the Company’s stock.

The fair values of the Company’s stock options granted during the six months ended June 30, 2020, were estimated using the following assumptions:

	2020 grants
Weighted average grant date fair value per share	$ 38.11 - 39.82
Expected volatility	35 - 42%
Expected term (in years)	6.25
Risk-free interest rate	0.46 - 1.80%
Expected dividend yield		0	%

23

These assumptions and estimates are as follows:

• Fair Value of Common Stock. The Company used the publicly quoted price as reported on the Nasdaq Global Select Market as the fair value of its common stock.

• Expected Term. The Company used the simplified method to determine the expected term.

• Risk-Free Interest Rate. The Company based the risk-free interest rate on U.S. Treasury zero-coupon yield curves with a remaining term equal to the expected term of the option.

• Expected Volatility. As the Company does not have an extensive trading history for its common stock, the expected volatility was derived using the historical volatility of the returns of comparable publicly traded companies combined with the brief trading history of the Company’s common stock.

Stock-based compensation expense

The stock-based compensation expense was recorded as follows (in thousands):

	Three Months Ended June 30,				Six Months Ended June 30,
	2020		2019		2020		2019
Cost of revenue – software	$	552	$	279	$	918	$	343
Research and development		1,830		579		3,258		937
Sales and marketing		1,273		475		2,000		937
General and administrative		879		747		1,529		1,075
Total stock-based compensation expense	$	4,534	$	2,080	$	7,705	$	3,292

11. Income taxes

At the end of each interim period, the Company makes its best estimate of the annual expected effective income tax rate and applies that rate to its ordinary year-to-date income (loss) before income taxes. The income tax provision or benefit related to unusual or infrequent items, if applicable, that will be separately reported or reported net of their related tax effects are individually computed and recognized in the interim period in which those items occur. In addition, the effect of changes in enacted tax laws or rates, tax status, judgment on the realizability of a beginning-of-the-year deferred tax asset in future years or income tax contingencies is recognized in the interim period in which the change occurs.

The computation of the annual expected effective income tax rate at each interim period requires certain estimates and assumptions including, but not limited to, the expected income (loss) before income taxes for the year, projections of the proportion of income (and/or loss) earned and taxed in respective tax jurisdictions, including applicable foreign taxes withheld at the source, permanent and temporary differences, and the likelihood of the realizability of deferred tax assets generated in the current year. Jurisdictions with a projected loss for the year or a year-to-date loss for which no tax benefit can be recognized due to a valuation allowance are excluded from the estimated annual effective tax rate. The impact of such an exclusion could result in a higher or lower effective tax rate during a particular quarter, based upon the composition and timing of actual earnings compared to annual projections. The estimates used to compute the provision or benefit for income taxes may change as new events occur, additional information is obtained or the Company’s tax environment changes. To the extent that the expected annual effective income tax rate changes, the effect of the change on prior interim periods is included in the income tax provision in the period in which the change in estimate occurs.

The Company’s income tax expense and effective tax rate for the three and six months ended June 30, 2020 and 2019, were as follows (in thousands, except percentages):

	Three Months Ended June 30,						Six Months Ended June 30,
	2020			2019			2020			2019
Income tax expense	$	2,768		$	(167	)	$	7,420		$	3,921
Effective tax rate		(37	%)		5	%		230	%		28	%

24

The tax rate is affected by the Company being a U.S. resident taxpayer, the tax rates in the U.S. and other jurisdictions in which the Company operates, the relative amount of income earned by jurisdiction and the relative amount of losses or income for which no benefit or expense is recognized due to a valuation allowance. The Company’s effective tax rate for the six months ended June 30, 2020 and 2019, also includes net discrete expense of $3.7 million and net discrete benefit of $1.2 million, respectively, primarily related to changes in reserves, changes in accruals for unremitted earnings and other adjustments.

On March 27, 2020, the Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”) was enacted in response to COVID-19. The CARES Act, among other things, permits NOL carryovers and carrybacks to offset 100% of taxable income for taxable years beginning before 2021. In addition, the CARES Act allows NOLs incurred in 2018, 2019, and 2020 to be carried back to each of the five preceding taxable years to generate a refund of previously paid income taxes. The CARES Act also provides a temporary relaxation of the limitation (reflected in section 163(j) of the Internal Revenue Code) on business interest expense deductions to 50% of adjusted taxable income for tax years beginning in 2019 and 2020, and an election to use 2019 adjusted taxable income for tax years beginning in 2020. The Company is currently evaluating the impact of the CARES Act, but at present does not expect that the NOL carryback provision of the CARES Act would result in a material tax benefit. The Company also does not expect the relaxation of section 163(j) provisions to have a material tax benefit since the Company is expected to be in a net interest income position. In addition, the Company has evaluated the COVID-19 related legislation globally and does not expect the legislation to have a material tax impact on the Company. Further, on July 23, 2020, the Department of Treasury published final regulations under the global intangible low-taxed income and Subpart F provisions of the Internal Revenue Code regarding the treatment of income that is subject to a high rate of foreign tax (“high-tax exclusion”). These regulations, among other things, permit U.S. shareholders of foreign corporations to make an election for a controlled foreign corporation to exclude from subpart F income any item of income received by the controlled foreign corporation if that income is subject to an effective tax rate greater than 90% of the maximum U.S. corporate income tax rate of 21%. The Company is in the process of evaluating the impact of these regulations and has not determined if an election should be made to avail the high-tax exclusion for tax years beginning January 1, 2018 or later.

13. Commitments and contingencies

Swedish Tax Litigation

The Swedish Tax Authorities, or STA, assessed tax (net of utilization of tax attributes), penalties and interest in the amount of $6.2 million related to the acquisition of Panopticon AB by Datawatch Corporation, in 2013 for the years 2013, 2014 and 2015. The STA, upon auditing the acquisition transaction, reached a conclusion that post acquisition, certain assets were removed from Sweden, triggering the tax obligation. The STA is also of the opinion that some services related to product development provided to the new parent company in the U.S. were performed by Panopticon AB at a price below market price triggering tax obligations. Datawatch contested the findings by the STA throughout the audit process including contesting the STA position in the first level of administrative courts. On May 29, 2019, the Administrative Court issued its ruling in favor of Datawatch AB. On July 4, 2019, the STA filed an appeal of the Administrative Court ruling with the Administrative Court of Appeal in Stockholm, effectively continuing to assert that the assessments are in fact appropriate. After relevant submissions by the Company and the STA, the Court of Appeals held a hearing on February 20, 2020. On March 27, 2020, the Court of Appeals issued its finding in favor of the STA. Pursuant to requirements in Sweden, the Company paid the assessed tax, penalties and interest on April 24, 2020. The Company, in accordance with its right to appeal the ruling to the Administrative Supreme Court of Sweden, filed an appeal of the Court of Appeals ruling citing specific grounds for reconsideration. Whether the Administrative Supreme Court will agree to hear the appeal is unknown at present. Further, even if the Administrative Supreme Court agrees to hear the appeal, there is no assurance that it will rule in favor of the Company.

Other legal proceedings

From time to time, the Company may be subject to legal proceedings and claims in the ordinary course of business. The Company has received, and may in the future continue to receive, claims from third parties asserting, among other things, infringement of their intellectual property rights. Future litigation may be necessary to defend the Company, its partners and its customers by determining the scope, enforceability and validity of third party proprietary rights, or to establish and enforce the Company’s proprietary rights. The results of any current or future litigation cannot be predicted with certainty and regardless of the outcome, litigation can have an adverse impact on the Company because of defense and settlement costs, diversion of management resources and other factors.

14. Segment information

The Company defines its operating segments as components of its business where separate financial information is available and used by the chief operating decision maker (“CODM”) in deciding how to allocate resources to its segments and in assessing performance. The Company’s CODM is its Chief Executive Officer.

The Company has identified two reportable segments for financial reporting purposes: Software and Client Engineering Services, or “CES”. The primary measure of segment operating performance is Adjusted EBITDA, which is defined as net income (loss) adjusted for income tax expense (benefit), interest expense, interest income and other, depreciation and amortization, stock-based compensation expense, restructuring charges, asset impairment charges and other special items as determined by management. Adjusted EBITDA includes an allocation of corporate headquarters costs.

The Software reportable segment derives revenue from the sale and lease of licenses for software products focused on the development and application of simulation technology to synthesize and optimize designs, processes and decisions for improved business performance. The Software segment also derives revenue from software support, upgrades, training and consulting services focused on product design and development expertise and analysis support from the component level up to complete product engineering at any stage of the lifecycle. To a much lesser extent, the Software segment also includes revenue from the sale of hardware products, primarily as a result of prior business acquisitions.

The Client Engineering Services reportable segment provides support to its customers with long-term ongoing product design and development expertise in its market segments of Solvers & Optimization, Modeling & Visualization, Industrial and Concept Design, and high performance computing. The Company hires simulation specialists, industrial designers, design engineers, materials experts, development and test specialists, manufacturing engineers and information technology specialists for placement at customer sites for specific customer-directed assignments.

The “All other” represents innovative services and products, including toggled^®, the Company’s LED lighting business. toggled^® is focused on developing and selling next-generation solid state lighting technology along with communication and control protocols based on intellectual property for the direct replacement of fluorescent light tubes with LED lamps, and for control of LED lighting. Other businesses combined within Other include the Company’s WEYV business, which ceased operations in the third quarter of 2019, and potential services and product concepts that are still in their development stages.

26

Inter-segment sales are not significant for any period presented. The CODM does not review asset information by segment when assessing performance, therefore, no asset information is provided for reportable segments. The accounting policies of the segments are the same as those described in Note 1 – Organization and summary of significant accounting policies.

Impact of COVID-19

In March 2020, The World Health Organization declared the outbreak of COVID-19 a pandemic, and a public health emergency of international concern. The global spread of COVID-19 has created significant volatility and uncertainty. Such conditions are expected to continue to persist. To limit the spread of COVID-19, governments have taken various actions from time to time including the issuance of travel restrictions, complete or partial prohibitions of non-essential activities, restrictions or shutdowns of non-essential businesses, stay-at-home orders and social distancing guidelines. Some of these actions have varied from initial responses, pivoting between full or complete to partial or limited restrictions depending upon local or regional conditions. Accordingly, many businesses have adjusted to these actions by reducing or suspending operating or other activities. This has negatively impacted several of the markets we serve, including the automotive and aerospace markets.

29

The ensuing discussion is provided to summarize the impacts of COVID-19 upon the Company, inclusive of some of the principal measures undertaken by the Company to date to respond to the pandemic. It is difficult to predict with any level of precision the broad effects of COVID-19 on specific industries or individual companies. Locally or regionally imposed restrictions in concert with the duration of pandemic conditions may create disparate impacts across the globe, including the primary countries or regions in which the Company and its customers operate.

The uncertain impact from the rapidly changing market and economic conditions due to COVID-19 has disrupted the business of many of our customers and partners. These disruptions have had an adverse effect on our business and consolidated results of operations and could impact our financial condition in the future. For example, a negative impact on our customers may cause them to request extended payment terms, delayed invoicing, higher discounts, lower renewal amounts or cancelations, and a reduction in demand for software related and client engineering services. These actions could have a negative impact on our financial results and liquidity. While adjustments in costs have been undertaken to mitigate the potential loss of revenue, including through the reduction in use of outside contractors and furloughing those employees associated with client engineering services for whom their associated customer contracts were interrupted or terminated, we believe that it is important on a long term basis to retain much of the deeply technical and specialized engineering resources typically engaged in providing software related services.

We have adopted several measures in response to COVID-19 adhering to local and regional restrictions, including instructing employees to work from home, adjusting our expenses and cash flow to correlate with potential declines in billings and cash collections from customers, shifting certain of our customer events to online-only webcasts and restricting non-critical business travel by our employees. Historically, a portion of field sales, professional services and other activities were conducted in person. Currently, because of travel restrictions related to COVID-19, substantially all of our sales, professional services and other activities are being conducted virtually. We have developed contingency plans to reduce costs further if the current situation changes. We continue to actively monitor business conditions and government mandates related to COVID-19 and may take further actions that alter our business operations as may be required by federal, state or local authorities or that we determine are in the best interests of our associates, customers, suppliers and shareholders.

Throughout this period, our response is focused on maintaining the health and safety of our employees, customers, and partners. We are committed to, and we believe we are capable of continuing to provide the same excellent level of service and technical support for our customers during these uncertain times. Our team is comfortable and highly experienced with remote collaboration, as it is a normal part of our global culture. During this crisis, customers working remotely can move their existing licenses from their on-premise servers to servers utilizing hosted Altair Units, or request temporary term-based software licenses for increased productivity and security. We are also providing access to an increased number of online training, marketing and sales resources.

We have almost entirely converted our business to being capable of operating nearly 100% “virtual” as required under COVID-19 restrictions, leveraging our global technology infrastructure.  While we are capable of sustained operations primarily in a virtual environment, we expect that we will gradually resume normal operations, when permitted, based on local conditions and restrictions, with the primary focus of preserving employee welfare, while continuing to support customers. We have undertaken many measures to manage ongoing operating expenses given the uncertainties with the COVID-19 environment. Specifically, we have introduced temporary wage reductions, or other measures, in accordance with local labor laws and regulations, to reduce near term compensation costs. We have, where possible, negotiated reductions in costs for consultants, professional and advisory fees, and other costs. Given global travel restrictions, we have substantially reduced expenses for travel related costs while many sales and marketing activities have reverted to being virtualized, further reducing certain expenditures on a net basis.

COVID-19 restrictions have begun to ease in certain jurisdictions, and we have been able to re-open offices in certain countries. On the other hand, certain jurisdictions that eased restrictions have subsequently heightened their restrictions. We have taken proactive steps to protect the health and safety of our employees, customers, and partners, preparing our offices for a safe return in compliance with local and regional regulations and requirements enacting rigorous safety measures, including employee training and self-monitoring for symptoms of COVID-19. Adhering to local and regional requirements, these measures include a combination of the taking of all employee temperatures upon reporting to work, encouraging employees to continue to work from home, implementing social distancing protocols, maintaining suspension of travel, instituting facility protocols and cleaning guidelines, establishing hand sanitizer stations, disinfecting workspaces, and requiring the wearing of masks with respect to those employees who must be physically present in their workplace. In the event an employee contracts the virus and tests positive for COVID-19, we have mandated quarantining and have instructed employees not to return to work until such time that they have been cleared to do so. We expect to continue to practice these measures until we determine that COVID-19 is adequately contained for purposes of our business, and we may take further actions as government authorities require or recommend or as we determine to be in the best interests of our employees, customers, and partners.

30

We derive a significant portion of our revenue from international operations, which are primarily conducted in foreign currencies. The value of the U.S. dollar has fluctuated in comparison to certain foreign currencies, including in Europe, driven by COVID-19 events and news. Since we have substantial international operations that arise from our normal business operations, our financial results in 2020 are expected to be impacted by COVID-19 driven variations in foreign currency exchange rates, apart from the traditional elements that underly foreign currency exchange rate changes.

We have performed an assessment of certain tangible and intangible assets to determine whether events or changes in circumstances caused by the COVID-19 pandemic resulted in indicators of impairment as of June 30, 2020. Based on present expectations, we determined that it is not more likely than not that indicators of impairment existed as of June 30, 2020. Notwithstanding this conclusion, if business conditions were to deteriorate in a significant manner or for an extended duration within our customer base, the likelihood of impairment would increase, and we would again assess whether events or changes in circumstances indicate that an asset impairment that is more likely than not exists. Specifically, certain non-amortizing intangible assets from recent acquisitions valued on the basis of short-term forecasts of revenue will be re-assessed for indicators of impairment and it is possible that an impairment charge will be reflected in the future should COVID-19 business conditions worsen or extend substantially in duration.

As reflected in our period to period analysis below, we believe the emergence of COVID-19 has negatively affected our results of operations. COVID-19’s impact on some of our customers has primarily contributed to the decrease in revenue for software related and client engineering services. Our software product revenue has been affected by elongated sales cycles, greater challenges in securing renewals, as well as new and expansion business. While we continue to robustly engage with our customers, primarily virtually, to mitigate the uncertain extent of the negative impact of COVID-19 on our customers, our ability to attract, serve, retain or expand customers will continue to be uncertain. Existing and potential customers may choose to reduce or delay technology spending in response to COVID-19, or attempt to renegotiate contracts and obtain concessions, which may materially and negatively impact our operating results, financial condition and prospects. In certain cases, we provided longer than normal payment terms to certain of our customers; however, the terms are less than one year, and we do not expect this to materially affect our consolidated financial statements. We are unable to accurately predict the full impact that COVID-19 will have due to numerous uncertainties, including the full scope of the disease, the duration of the initial outbreak, the number and intensity of subsequent waves of infections, actions that may be taken by governmental authorities, the impact to the businesses of our customers and partners, the development of treatments and vaccines, and other factors identified in Part II, Item 1A “Risk Factors” in this Form 10-Q. Even after the COVID-19 pandemic has subsided, we may experience material adverse impacts to our business as a result of any economic recession or depression that has occurred or may occur in the future. We will continue to evaluate the nature and extent of the impact to our business, consolidated results of operations, and financial condition.

Factors Affecting our Performance

We believe that our future success will depend on many factors, including those described below. While these areas present significant opportunity, they also present risks that we must manage to achieve successful results. If we are unable to address these challenges, our business, operating results and prospects could be harmed. Please see “Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2019, as filed with the SEC on March 2, 2020, and in Part II, Item 1A of this Quarterly Report on Form 10-Q.

Seasonality and quarterly results

Our billings have historically been highest in the first and fourth quarters of any calendar year and may vary in future quarters. The timing of recording billings and the corresponding effect on our cash flows may vary due to the seasonality of the purchasing and payment patterns of our customers. In addition, the timing of the recognition of revenue, the amount and timing of operating expenses, including employee compensation, sales and marketing activities, and capital expenditures, may vary from quarter-to-quarter which may cause our reported results to fluctuate significantly. In addition, we may choose to grow our business for the long-term rather than to optimize for profitability or cash flows for a particular shorter-term period. This seasonality or the occurrence of any of the factors above may cause our results of operations to vary and our financial statements may not fully reflect the underlying performance of our business.

Integration of recent acquisitions

We believe that our recent and prior acquisitions result in certain benefits, including expanding our portfolio of software and products and enabling us to better serve our customer’s requests for data intelligence and simulation technology. However, to realize some of these anticipated benefits, the acquired businesses must be successfully integrated. The success of these acquisitions will depend in part on our ability to realize these anticipated benefits. We may fail to realize the anticipated benefits of these acquisitions for a variety of reasons.

31

Foreign currency fluctuations

Because of our substantial international operations, we are exposed to foreign currency risks that arise from our normal business operations, including in connection with our transactions that are denominated in foreign currencies, including the Euro, British Pound Sterling, Indian Rupee, Japanese Yen, and Chinese Yuan. To present the changes in our underlying business without regard to the impact of currency fluctuations, we evaluate certain of our operating results both on an as reported basis, as well as on a constant currency basis.

Constant currency amounts exclude the effect of foreign currency fluctuations on our reported results. Our comparative financial results were impacted by fluctuations in the value of the United States dollar relative to other currencies during the three and six months ended June 30, 2020, as compared to the three and six months ended June 30, 2019. To present this information, the results for 2020 for entities whose functional currency is a currency other than the United States dollar were converted to United States dollars at rates that were in effect for 2019. These adjusted amounts are then compared to our current period reported amounts to provide operationally driven variances in our results.

The effects of currency fluctuations on our Revenue, Net income, Adjusted EBITDA and Billings, are reflected in the table below. Amounts in brackets indicate a net adverse impact from currency fluctuations.

	Three Months Ended			Six Months Ended
(in thousands)	June 30, 2020			June 30, 2020
Revenue	$	(1,471	)	$	(3,071	)
Net income	$	11		$	(345	)
Adjusted EBITDA	$	(7	)	$	(316	)
Billings	$	(1,152	)	$	(4,046	)

Expanded use of our software applications

Our ability to grow our revenue is affected, in part, by the pace at which our customers continue to expand their use of our design, simulation, optimization and analysis applications, our suite of data intelligence products and the degree to which prospective customers realize the benefit of using our software applications. To grow our presence within our customers and attract new customers, we devote substantial sales and marketing resources to drive increased adoption across our existing customers and encourage new customers to commence using our software. As a result of this “land and expand” business model, we expect to generate additional revenue from our current and future customer base. To the extent our sales and marketing efforts do not translate into customer retention or expansion, or if we do not allocate those expenses efficiently, our financial performance may be adversely affected. Therefore, our financial performance will depend in part on the degree to which our “land and expand” strategies are successful.

Altair Units

In July 2020, we introduced Altair Units, our new, unified licensing system that gives access to every Altair product and the power to solve on any scale. The new model delivers enhanced inclusivity at various price points and will allow customers to maximize their software value.

Investments for growth

We have made and plan to continue to make investments for long-term growth, including investments in our ongoing research and development activities seeking to create new software and to enhance our existing applications to address emerging technology trends and additional customer needs. Generally, the development of new or improved applications in our software can result in the expansion of our user base within an organization and a potential increase in revenue over time, although the expenditures associated with such developments may adversely affect our performance in the near term. We intend to continue to invest resources in sales and marketing, by further expanding our sales teams and increasing our marketing activities. Our ability to continue to grow revenue from our current and potential customer base is dependent, in part, upon the success of our current and future research and development and sales and marketing activities.

32

Business Segments

We have identified two reportable segments: Software and Client Engineering Services:

• Software —Our Software segment includes software and software related services. The software component of this segment includes our portfolio of software products including our solvers and optimization technology products, modeling and visualization tools, data analytics and analysis products, high performance computing, software applications and hardware products, IoT platform and analytics tools as well as support and the complementary software products we offer through our Altair Partner Alliance, or APA. The APA includes technologies ranging from computational fluid dynamics and fatigue to manufacturing process simulation and cost estimation. The software related services component of this segment includes consulting, implementation services, and training focused on product design and development expertise and analysis from the component level up to complete product engineering at any stage of the lifecycle.

• Client Engineering Services —Our client engineering services, or CES, segment provides client engineering services to support our customers with long-term, ongoing expertise. We operate our CES business by hiring engineers and data scientists for placement at a customer site for specific customer-directed assignments. We employ and pay them only for the duration of the placement.

Our other businesses which do not meet the criteria to be separate reportable segments are combined and reported as “Other” which represents innovative services and products, including toggled, our LED lighting business. toggled is focused on developing and selling next-generation solid state lighting technology along with communication and control protocols based on our intellectual property for the direct replacement of fluorescent light tubes with LED lamps. Other businesses combined within Other include our WEYV business, which ceased operations in the third quarter of 2019, and potential services and product concepts that are still in development stages.

For additional information about our reportable segments and other businesses, see Note 14 in the Notes to consolidated financial statements in Item 1, Part I of this Quarterly Report on Form 10-Q.

The tax rate is affected by the Company being a U.S. resident taxpayer, the tax rates in the U.S. and other jurisdictions in which the Company operates, the relative amount of income earned by jurisdiction and the relative amount of losses or income for which no benefit or expense is recognized due to a valuation allowance. The Company’s effective tax rate for the three months ended June 30, 2020 and 2019, also includes net discrete expense of $1.7 million and net discrete benefit of $0.1 million, respectively, primarily related to changes in reserves, changes in accruals for unremitted earnings and other adjustments.

Our CES business is primarily affected by customer demand and our ability to fill customers’ open positions. As noted above in response to COVID-19, in April some of our CES customers furloughed staff positions, while some other customers reduced CES staff working hours or reduced billing rates. We have acted in concert with those customers to furlough or curtail the hours and compensation of those impacted employees until such time as our customers return to normal staffing, billing rates, or required working hours. The 4% decrease in CES revenue for the six months ended June 30, 2020, as compared to the six months ended June 30, 2019, reflects those steps, offset in part by our ability to fulfill demand for our client engineering services in the first quarter of 2020.

Billings.  Billings consists of our total revenue plus the change in our deferred revenue, excluding deferred revenue from acquisitions during the period. Given that we generally bill our customers at the time of sale, but typically recognize a portion of the related revenue ratably over time, management believes that Billings is a meaningful way to measure and monitor our ability to provide our business with the working capital generated by upfront payments from our customers.

Adjusted EBITDA.  We define Adjusted EBITDA as net income (loss) adjusted for income tax expense (benefit), interest expense, interest income and other, depreciation and amortization, stock-based compensation expense, restructuring charges, asset impairment charges and other special items as determined by management. Our management team believes that Adjusted EBITDA is a meaningful measure of performance as it is commonly utilized by management and the investment community to analyze operating performance in our industry.

Free Cash Flow.  Free Cash Flow is a non-GAAP measure that we calculate as cash flow provided by operating activities less capital expenditures. Management believes that Free Cash Flow is useful in analyzing our ability to service and repay debt, when applicable, and return value directly to stockholders.

These non-GAAP financial measures reflect an additional way of viewing aspects of our business that, when viewed with our GAAP results and the accompanying reconciliations to the corresponding GAAP financial measures included in the tables below, may provide a more complete understanding of factors and trends affecting our business. These non-GAAP financial measures should not be relied upon to the exclusion of GAAP financial measures and are by definition an incomplete understanding of the Company and must be considered in conjunction with GAAP measures.

43

We believe that the non-GAAP measures disclosed herein are only useful as an additional tool to help management and investors make informed decisions about our financial and operating performance and liquidity. By definition, non-GAAP measures do not give a full understanding of the Company. To be truly valuable, they must be used in conjunction with the comparable GAAP measures. In addition, non-GAAP financial measures are not standardized. It may not be possible to compare these financial measures with other companies’ non-GAAP financial measures having the same or similar names. We strongly encourage investors to review our consolidated financial statements and the notes thereto in their entirety and not rely on any single financial measure.

The following table provides a reconciliation of Billings to revenue, the most comparable GAAP financial measure, for each of the periods presented:

⁽¹⁾ Includes $0.6 million of severance expense for the three and six months ended June 30, 2020. Includes 0.8 million and $1.0 million of impairment charges for royalty contracts for the three and six months ended June 30, 2019, respectively.  

The following table provides a reconciliation of Free Cash Flow to net cash provided by operating activities, the most comparable GAAP financial measure, for each of the periods presented:

	Six Months Ended June 30,
(in thousands)	2020			2019
Net cash provided by operating activities	$	33,401		$	31,868
Capital expenditures		(2,530	)		(6,667	)
Free cash flow	$	30,871		$	25,201

Recurring Software License Rate.  A key factor to our success is our recurring software license rate which we measure through Billings, primarily derived from annual renewals of our existing subscription customer agreements. We calculate our recurring software license rate for a particular period by dividing (i) the sum of software term-based license Billings, software license maintenance Billings, and 20% of software perpetual license Billings which we believe approximates maintenance as an element of the arrangement by (ii) the total software license Billings including all term-based subscriptions, maintenance, and perpetual license billings from all customers for that period. For the six months ended June 30, 2020 and 2019, our recurring software license rate was 93% and 91%, respectively. The recurring software license rate may vary from period to period.

44

Liquidity and capital resources

Our principal sources of liquidity have been the net payments received from global customers using our software and services and proceeds from our initial public offering, follow-on offering and our convertible debt offering, as well as periodic draws on our credit facilities, when needed.

We have commenced the initial planning to update zoning to allow for future expansion of our corporate headquarters facilities on the adjacent property we own to enable development consistent with our long-term needs.  We have not yet determined the nature and scope of the overall timeline and investment beyond the immediate rezoning efforts necessary for our potential use in the future. Over the next 12 months, we expect to continue to advance this project, although we are considering the emerging business impacts of COVID-19 on the nature and timing of this project.

We continue to evaluate possible acquisitions and other strategic transactions designed to expand our business. As a result, our expected uses of cash could change, our cash position could be reduced, or we may incur additional debt obligations to the extent we complete additional acquisitions.

Our existing cash and cash equivalents may fluctuate during fiscal 2020, due to changes in our planned cash expenditures, including changes in incremental costs such as direct costs and integration costs related to acquisitions. Cash from operations could also be affected by various risks and uncertainties, including, but not limited to, the effects of COVID-19. It is possible that certain customers may unilaterally decide to extend payments on accounts receivable, however the Company’s customer base is comprised primarily of larger organizations with previously strong liquidity and capital resources.  

We believe that our existing cash balances, together with funds generated from operations and amounts available under our credit facility, will be sufficient to finance our operations and meet our foreseeable cash requirements for the next twelve months. We also believe that our financial resources, along with managing discretionary expenses, will allow us to manage the anticipated impact of COVID-19 on our business operations for the foreseeable future, which could include reductions in revenue and delays in payments from customers and partners. We will continue to evaluate our financial position as developments evolve relating to COVID-19.

Revolving credit facility

We have a $150.0 million credit facility with a maturity date of December 15, 2023 (“2019 Amended Credit Agreement”). The 2019 Amended Credit Agreement allows us to request that the aggregate commitments under the 2019 Amended Credit Agreement be increased by up to $50.0 million for a total of $200.0 million, subject to certain conditions.

As of June 30, 2020, we had no outstanding borrowings under the 2019 Amended Credit Agreement and there was $150.0 million available for future borrowing. The 2019 Amended Credit Agreement is available for general corporate purposes, including working capital, capital expenditures and permitted acquisitions. At June 30, 2020, we were in compliance with the financial covenants.

For additional information about the 2019 Amended Credit Agreement, see Note 6 in the Notes to consolidated financial statements in Item 1, Part I of this Quarterly Report on Form 10-Q.

Cash flows

As of June 30, 2020, we had aggregate cash and cash equivalents of $250.5 million available for working capital purposes, acquisitions, and capital expenditures; $194.0 million of this aggregate amount was held in the United States and $46.9 million was held in the APAC and EMEA regions with the remainder held in Canada, Mexico and South America.

Other than statutory limitations, there are no significant restrictions on the ability of our subsidiaries to pay dividends or make other distributions to Altair. Based on our current liquidity needs and repatriation strategies, we expect that we can manage our global liquidity needs without material adverse tax implications. The 2017 changes in U.S. tax law could materially affect our tax obligations. For further discussion, please see our 2019 Annual Report on Form 10-K, “Item 1A. Risk Factors – New legislations or tax-reform policies that would change U.S. or foreign taxation of international business activities, including uncertainties in the interpretation and application of the 2017 Tax Cuts and Jobs Act, could materially affect our tax obligations and effective tax rate.”

45

The following table summarizes our cash flows for the periods indicated:

	Six Months Ended June 30,
(in thousands)	2020			2019
Net cash provided by operating activities	$	33,401		$	31,868
Net cash used in investing activities		(5,091	)		(7,704	)
Net cash provided by financing activities		267			192,144
Effect of exchange rate changes on cash, cash equivalents and restricted cash		(1,148	)		187
Net increase in cash, cash equivalents and restricted cash	$	27,429		$	216,495

Net cash provided by operating activities

Net cash provided by operating activities for the six months ended June 30, 2020 was $33.4 million, which reflects an increase of $1.5 million compared to the six months ended June 30, 2019. This increase was the result of changes to our working capital position, offset in part by a decrease in our net income for the six months ended June 30, 2020, as compared to the six months ended June 30, 2019.

Net cash used in investing activities

Net cash used in investing activities for the six months ended June 30, 2020 was $5.1 million, which reflects a decrease of $2.6 million compared to the six months ended June 30, 2019. This decrease was primarily the result of a reduction in cash payments for capital expenditures in the six months ended June 30, 2019.

Net cash provided by financing activities

Net cash provided by financing activities for the six months ended June 30, 2020 was $0.3 million, compared to cash provided by financing activities of $192.2 million for the six months ended June 30, 2019. For the six months ended June 30, 2019, we received aggregate proceeds of $223.1 million from our Convertible Notes offering, net of underwriters’ discounts and commissions, and we had net cash payments on our revolving commitment of $31.0 million. We did not have any borrowings for the six months ended June 30, 2020.

Effect of exchange rate changes on cash, cash equivalents and restricted cash

There were adverse effects of exchange rate changes on cash, cash equivalents and restricted cash of $1.2 million for the six months ended June 30, 2020, compared to favorable effects of exchange rate changes on cash, cash equivalents and restricted cash of $0.2 million for the six months ended June 30, 2019.

Off-balance sheet arrangements

Through June 30, 2020, we did not have any relationships with unconsolidated organizations or financial partnerships, such as structured finance or special purpose entities that would have been established for the purpose of facilitating off-balance sheet arrangements or other contractually narrow or limited purposes.

Recently issued accounting pronouncements

See Note 2 in the Notes to consolidated financial statements in Item 1, Part I of this Quarterly Report on Form 10-Q for a full description of the recent accounting pronouncements and our expectation of their impact, if any, on our results of operations and financial condition.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

We are exposed to certain global market risks, including foreign currency exchange risk and interest rate risk associated with our debt.

46

Foreign Currency Risk

As a result of our substantial international operations, we are exposed to foreign currency risks that arise from our normal business operations, including in connection with our transactions that are denominated in foreign currencies. In addition, we translate sales and financial results denominated in foreign currencies into United States dollars for purposes of our consolidated financial statements. As a result, appreciation of the United States dollar against these foreign currencies generally will have a negative impact on our reported revenue and operating income while depreciation of the United States dollar against these foreign currencies will generally have a positive effect on reported revenue and operating income.

To date, we have not entered into any foreign currency hedging contracts, since exchange rate fluctuations have not had a material impact on our operating results and cash flows. Based on our current international structure, we do not plan on engaging in hedging activities in the near future.

Market Risk and Market Interest Risk

In June 2019, we issued $230.0 million aggregate principal amount of 0.250% convertible senior notes due 2024. Our Convertible Notes have fixed annual interest rates at 0.250% and, therefore, we do not have economic interest rate exposure on our Convertible Notes. However, the value of the Convertible Notes is exposed to interest rate risk. Generally, the fair market value of our fixed interest rate Convertible Notes will increase as interest rates fall and decrease as interest rates rise. In addition, the fair values of the Convertible Notes are affected by our stock price. The fair value of the Convertible Notes will generally increase as our Class A common stock price increases in value and will generally decrease as our Class A common stock price declines in value. Additionally, we carry the Convertible Notes at face value less unamortized discount and issuance costs on our balance sheet, and we present the fair value for required disclosure purposes only.

As of June 30, 2020, we had cash, cash equivalents and restricted cash of $250.9 million, consisting primarily of bank deposits and money market funds. At June 30, 2020, we had no outstanding borrowings under our 2019 Amended Credit Agreement. Such interest-bearing instruments carry a degree of interest rate risk; however, historical fluctuations of interest expense have not been significant.

Interest rate risk relates to the gain/increase or loss/decrease we could incur on our debt balances and interest expense associated with changes in interest rates. Changes in interest rates would impact the amount of interest income we realize on our invested cash balances. It is our policy not to enter into derivative instruments for speculative purposes, and therefore, we hold no derivative instruments for trading purposes.

Item 4. Controls and Procedures

The Company maintains disclosure controls and procedures (as defined in Rule 13a-15(e) or 15d-15(e) of the Exchange Act) that are designed to ensure that information required to be disclosed in periodic reports filed with the SEC under the Securities Exchange Act of 1934 is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms, and that such information is accumulated and communicated to the Company’s management, including its Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure. Under the supervision and with the participation of our management, including the Chief Executive Officer and Chief Financial Officer, we have evaluated the effectiveness of our disclosure controls and procedures as defined in Rule 13(a)-15(e) under the Exchange Act as of the end of the period covered by this report. Based on that evaluation, the Chief Executive Officer and Chief Financial Officer have concluded that our disclosure controls and procedures were effective as of June 30, 2020.

Changes in Internal Control Over Financial Reporting

There was no change in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) that occurred during the quarter ended June 30, 2020, that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

PART II – OTHER INFORMATION

Item 1. Legal Proceedings

Swedish Tax Litigation

The Swedish Tax Authorities, or STA, have assessed tax (net of utilization of tax attributes), penalties and interest in the amount of $6.2 million related to the acquisition of Panopticon AB by Datawatch Corporation, in 2013 for the years 2013, 2014 and 2015. The STA, upon auditing the acquisition transaction, reached a conclusion that post acquisition, certain assets were removed from Sweden, triggering the tax obligation. The STA is also of the opinion that some services related to product development provided to the new parent company in the U.S. were performed by Panopticon AB at a price below market price triggering tax obligations. Datawatch contested the findings by the STA throughout the audit process including contesting the STA position in the first level of administrative courts. On May 29, 2019, the Administrative Court issued its ruling in favor of Datawatch AB. On July 4, 2019, the STA filed an appeal of the Administrative Court ruling with the Administrative Court of Appeal in Stockholm, effectively continuing to assert that the assessments are in fact appropriate. After relevant submissions by the Company and the STA, the Court of Appeals held a hearing on February 20, 2020. 

On March 27, 2020, the Court of Appeals issued its finding in favor of the STA. Pursuant to requirements in Sweden, the Company paid the assessed tax, penalties and interest on April 24, 2020. The Company, in accordance with its right to appeal the ruling to the Administrative Supreme Court of Sweden, filed an appeal of the Court of Appeals ruling citing specific grounds for reconsideration.  Whether the Administrative Supreme Court will agree to hear the appeal is unknown at present.  Further, even if the Administrative Supreme Court agrees to hear the appeal, there is no assurance that it will rule in favor of the Company.

As previously described in the Company’s Annual Report on Form 10-K for the year ended December 31, 2019, the Company is subject to legal proceedings for which there were no other material changes during the six months ended June 30, 2020.

Item 1A. Risk Factors

The risk factor set forth below supplements the risk factors previously disclosed in Part I, Item 1A. "Risk Factors" in the Company’s Annual Report on Form 10-K for the year ended December 31, 2019.

The COVID-19 pandemic, or other potential future pandemics or events, may cause severe business interruptions either globally or regionally, that could have a negative impact on our financial results.

In March 2020, the World Health Organization declared the outbreak of a novel coronavirus (COVID-19) pandemic. The outbreak of the COVID-19 pandemic has significantly affected our customers, the global economy and financial markets. The full extent to which COVID-19 will impact global or regional economies will depend on future developments that are highly uncertain and cannot be accurately predicted. New information is likely to emerge concerning COVID-19 and the actions to contain it or treat it with uncertain economic impact on local, regional, national and international markets. The Company's future results of operations, financial condition and cash flows could be materially adversely affected by COVID-19, particularly if the pandemic persists for a significant amount of time causing a substantial longer-term contraction in business for the Company’s customer base, prior to eventual recovery.  

Many governments have enacted a rapid massive global response leveraging monetary and fiscal policy to mitigate long term economic harm, while providing short term economic support. While the implementation of policy responses varies country by country, and regionally, the totality of the global response is based upon expectations that the response will serve to minimize the chance for a deep prolonged negative economic impact from COVID-19. Certain jurisdictions have begun to “re-open” their economies, within a relatively short time period of having engaged in substantial closure of most economic activity. Other jurisdictions have begun to consider moves to gradually “re-open” or have actually “re-opened”. In certain instances, governments deemed it necessary to reverse re-opening planning. The long term outcome of mitigation efforts is presently uncertain.

Additional risks from COVID-19 include the inability of our employees and those businesses upon which we rely for operations to carry out their responsibilities at levels of performance necessary to maintain our performance undisturbed as a result of measures taken by governmental authorities to limit the spread of COVID-19. It is possible that some of our furloughed CES personnel do not return to work when their positions return. COVID-19 may also affect our operating and financial results in a manner that is not presently known to us, or that we currently to do not consider presenting significant risks to our operations.

Organization Consolidation And Presentation Of Financial Statements [Abstract]

Organization and Description of Business

1. Organization and description of business

Altair Engineering Inc. (“Altair” or the “Company”) is incorporated in the state of Delaware. The Company is a global technology company providing software and cloud solutions in the areas of product development, high performance computing and data analytics. Altair enables organizations across broad industry segments to compete more effectively in a connected world while creating a more sustainable future. The Company is headquartered in Troy, Michigan.

Basis of presentation

The accompanying unaudited consolidated financial statements have been prepared in accordance with United States generally accepted accounting principles (“GAAP”) and applicable rules and regulations of the Securities and Exchange Commission (“SEC”) regarding interim financial information.  Accordingly, the accompanying statements do not include all the information and notes required by GAAP for complete financial statements. The accompanying unaudited consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements (and notes thereto) for the year ended December 31, 2019, included in the most recent Annual Report on Form 10-K filed with the SEC. In the opinion of management, all adjustments considered necessary for a fair presentation of the financial statements have been included, and all adjustments are of a normal and recurring nature. The preparation of the financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, and disclosures of contingent assets and liabilities at the date of the financial statements and reported amounts of revenue and expenses during the reporting periods. Considerable judgment is often involved in making these determinations; use of different assumptions could result in significantly different results. Management believes its assumptions and estimates are reasonable and appropriate. However, actual results may differ from those estimates.  In addition, the results of operations for the three and six months ended June 30, 2020, are not necessarily indicative of the results that may be expected for any future period.

Use of estimates

The preparation of the consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and reported amounts of revenue and expenses during the reporting periods. On an ongoing basis, management evaluates its significant estimates including the stand alone selling price, or SSP, for each distinct performance obligation included in customer contracts with multiple performance obligations, valuation of acquired intangible assets in business combinations, the incremental borrowing rate used in the valuation of lease liabilities, the determination of the period of benefit for capitalized costs to obtain a contract, fair value of convertible senior notes, provision for credit loss, tax valuation allowances, liabilities for uncertain tax provisions, impairment of goodwill and intangible assets, retirement obligations, useful lives of intangible assets, revenue for fixed price contracts, and stock-based compensation. Actual results could differ from those estimates.

COVID-19

In March 2020, The World Health Organization declared the outbreak of COVID-19 a pandemic, and a public health emergency of international concern. The global spread of COVID-19 created significant volatility and uncertainty. Such conditions are expected to continue to persist. To limit the spread of COVID-19, governments have taken various actions from time to time including the issuance of travel restrictions, complete or partial prohibitions of non-essential activities, restrictions or shutdowns of non-essential businesses, stay-at-home orders and social distancing guidelines. Some of these actions have varied from initial responses, pivoting between full or complete to partial or limited restrictions depending upon local or regional conditions. Accordingly, many businesses have adjusted to these actions by reducing or suspending operating or other activities. This has negatively impacted several of the markets the Company serves, including the automotive and aerospace markets.

The Company continues to robustly engage with its customers, primarily virtually. While the Company believes this active level of engagement may mitigate potential and evolving negative impacts from COVID-19, existing and potential customers may choose to reduce or delay technology spending in response to COVID-19, or attempt to renegotiate contracts and obtain concessions, which may materially and negatively impact the Company’s operating results, financial condition and new business. In certain cases, the Company has provided longer than normal payment terms to certain of its customers; however, the terms are less than one year, and the Company does not expect this to materially affect its consolidated financial statements. COVID-19’s

impact on some of the Company’s customers has primarily contributed to the decrease in revenue for software related and client engineering services. The Company’s software product revenue has been affected by elongated sales cycles for some of its customers along with greater challenges in securing new and expansion business. The Company is unable to accurately predict the full impact that COVID-19 will have due to numerous uncertainties, including the full scope of the disease, the duration of the initial outbreak or the number and intensity of subsequent waves of infections, actions that may be taken by governmental authorities, the impact to the businesses of the Company’s customers and partners, and the development of treatments and vaccines. Even after the COVID-19 pandemic has subsided, the Company may experience material adverse impacts to its business as a result of any economic recession or depression that has occurred or may occur in the future. The Company will continue to evaluate the nature and extent of the impact to its business, consolidated results of operations, and financial condition.

Cash, cash equivalents and restricted cash

The Company considers all highly liquid investments with original or remaining maturities of 90 days or less at the date of purchase to be cash equivalents. Cash and cash equivalents are recorded at cost, which approximates fair value. Restricted cash is included in other long-term assets on the consolidated balance sheets. The following table provides a reconciliation of cash, cash equivalents and restricted cash reported in the consolidated balance sheets that sum to the total of the amounts reported in the consolidated statement of cash flows (in thousands):

	June 30, 2020		December 31, 2019
Cash and cash equivalents	$	250,540	$	223,117
Restricted cash included in other long-term assets		386		380
Total cash, cash equivalents, and restricted cash	$	250,926	$	223,497

Restricted cash represents amounts required for a contractual agreement with an insurer for the payment of potential health insurance claims, and term deposits for bank guarantees.

Inventory

Inventory consists of finished goods and is stated at the lower of cost and net realizable value. Cost is determined using the first-in, first-out method. Net realizable value is the estimated selling prices in the ordinary course of business, less reasonable predictable costs of completion, disposal and transportation. The valuation of inventory requires management to estimate excess inventory as well as inventory that is not of saleable quality. The determination of obsolete or excess inventory requires management to estimate market conditions and future demand for the Company’s products. Inventory was $2.8 million and $2.4 million at June 30, 2020 and December 31, 2019, respectively, and is included in prepaid expenses and other current assets in the consolidated balance sheets.

Receivable for French R&D credit

The French government provides a research and development (“R&D”) tax credit known as Credit Impôt Recherche, or CIR, in order to encourage Companies to invest in R&D activities. The tax credit is deductible from French income tax and any excess is carried forward three years. After three years, any unused credit may be reimbursed to the Company by the French government. As of June 30, 2020, the Company had approximately $13.7 million of receivables from the French government related to CIR, of which $2.5 million was recorded in income tax receivable and the remaining $11.2 million was recorded in other long-term assets. As of December 31, 2019, the Company had approximately $12.1 million of receivables from the French government related to CIR, of which $2.5 million was recorded in income tax receivable and the remaining $9.6 million was recorded in other long-term assets. CIR is subject to customary audit by French tax authorities.

Mezzanine equity

In 2017, the Company issued 200,000 shares of Class A common stock to a third party as partial consideration for the purchase of developed technology. These shares have a put right that can be exercised by the holder five years from date of purchase at $12.50 per share that requires the shares to be recorded at fair value at the issuance date and classified as mezzanine equity in the consolidated balance sheet. The put right option is terminated if the shareholders sell their shares. As of December 31, 2017, the Company concluded that it is no longer probable that the put option will be exercised as the put value is substantially below market value and subsequent adjustment is not required.

During the quarter ended June 30, 2020, the third party holder sold 133,336 shares on the open market and as a result, the issuance value of those shares was reclassified into permanent equity out of mezzanine equity. The remaining 66,664 shares shall remain as mezzanine equity until one of the following three events take place: (1) the shares are sold on the open market; (2) a redemption feature lapses; or (3) there is a modification of the terms of the instrument.

Accounting Changes And Error Corrections [Abstract]

Recent Accounting Guidance

2. Recent accounting guidance

Accounting standards adopted

Credit Losses – In June 2016, the FASB issued ASU 2016-13, Financial Instruments — Credit Losses (Topic 326):  Measurement of Credit Losses on Financial Instruments. The ASU significantly changes how entities will measure credit losses on most financial assets. The Company adopted ASU 2016-13 effective January 1, 2020 and recorded a cumulative effect adjustment to retained earnings of $0.4 million related to the adoption of ASU 2016-13; prior periods have not been adjusted. Under this new accounting standard, beginning January 1, 2020, an allowance for expected credit losses for groups of billed and unbilled receivables and contract assets that share similar risk characteristics is recorded based on an evaluation of historical loss experience, current conditions, and reasonable and supportable forecasts. Accounts are written off when it becomes apparent that such amounts will not be collected, generally when amounts are past due by greater than one year. Generally, the Company does not require collateral or charge interest on accounts receivable. Accounts receivable were reported net of an allowance for doubtful accounts of $2.4 million and $1.4 million at June 30, 2020 and December 31, 2019, respectively. 

Subsequent to adoption, the Company considered the impact of COVID-19 on its historical credit loss rates and made an adjustment to increase expected credit loss rates. The impact resulting from the increased credit loss rates did not have a material effect on the Company’s consolidated financial statements.

Fair Value – In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework – Changes to the Disclosure Requirements for Fair Value Measurement. This ASU modifies the disclosure requirements for fair value measurements, by removing, modifying, or adding certain disclosures. The Company adopted ASU 2018-13 on January 1, 2020. The adoption of this guidance did not have a material effect on the Company’s consolidated financial statements.

Intangibles – In August 2018, the FASB issued ASU 2018-15, Intangibles – Goodwill and Other – Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That is a Service Contract. This ASU clarifies and aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software. The Company adopted ASU 2018-15 on January 1, 2020, on a prospective basis. The adoption of this guidance did not have a material effect on the Company’s consolidated financial statements.

Accounting standards not yet adopted 

Retirement Benefits – In August 2018, the FASB issued ASU 2018-14, Compensation – Retirement Benefits- Defined Benefit Plans – General (Subtopic 715-20): Disclosure Framework – Changes to the Disclosure Requirements for Defined Benefit Plans. This ASU modifies the disclosure requirements for defined benefit pension or other postretirement plans. The amendments are effective for fiscal years ending after December 15, 2020; early adoption is permitted. The Company is currently evaluating the impact of the new guidance on its consolidated financial statements and related disclosures and does not expect this guidance to have a material effect on its consolidated financial statements.

Income Taxes – In December 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes. This ASU simplifies the accounting for income taxes by removing certain exceptions to the general principles in Topic 740 and improves consistent application of GAAP for other areas of Topic 740 by clarifying and amending existing guidance. The amendments are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2020; early adoption is permitted. The Company is currently evaluating the impact of the new guidance on its consolidated financial statements and related disclosures and does not expect this guidance to have a material effect on its consolidated financial statements.

Reference Rate Reform – In March 2020, the FASB issued ASU 2020-04. Reference Rate Reform (Topic 848) - Facilitation of the Effects of Reference Rate Reform on Financial Reporting. This ASU provides optional expedients and exceptions for applying U.S. GAAP to contract modifications and hedging relationships, subject to meeting certain criteria, that reference LIBOR or another rate that is expected to be discontinued. The amendments in the guidance are effective for all entities as of March 12, 2020 through December 31, 2022. The Company is currently evaluating the impact of this new guidance on its consolidated financial statements and related disclosures and does not expect this guidance to have a material effect on its consolidated financial statements.

Revenue from Contracts with Customers

Revenue From Contract With Customer [Abstract]

Revenue from Contracts with Customers

3. Revenue from contracts with customers

Revenue recognition

Software revenue

Revenue is derived principally from the licensing of software products and from related maintenance contracts. The Company enters into contracts that include combinations of products, maintenance and services, which are accounted for as separate performance obligations with differing revenue recognition patterns.

Revenue from term-based software licenses is classified as software revenue. Term-based licenses are sold only as a bundled arrangement that includes the rights to a term-based software license and post-contract customer support (PCS), which includes unspecified technical enhancements and customer support. Maximizing the use of observable inputs, the Company determined that a majority of the estimated standalone selling prices of the term-based license is attributable to the term-based license and a minority is attributable to the PCS. The license component is classified as license revenue and recognized as revenue upon the later of delivery of the licensed product or the beginning of the license period. PCS is classified as maintenance and other services and is recognized ratably over the term of the contract, as the Company provides the PCS benefit over time as a stand ready to perform obligation.

In addition to term-based software licenses, the Company sells perpetual licenses. Software revenue is recognized upon the later of delivery of the licensed product or the beginning of the license period. Typically, the Company’s perpetual licenses are sold with PCS. The Company allocates value in bundled perpetual and PCS arrangements based on the value relationship between the software license and maintenance. Revenue from PCS is classified as maintenance and other services and is recognized ratably over the term of the contract, as the Company satisfies the PCS performance obligation over time as a stand ready to perform obligation.

Revenue from training, consulting and other services is recognized as the services are performed, and is classified as maintenance and other services in the consolidated statement of operations. For contracts in which the service consists of a single performance obligation, such as providing a training class to a customer, the Company recognizes revenue upon completion of the performance obligation. For service contracts that are longer in duration and often include multiple performance obligations (for example, point-in-time training and consulting), the Company measures the progress toward completion of the obligations and recognizes revenue accordingly. In measuring progress towards the completion of performance obligations, the Company typically utilizes output-based estimates for services with fixed fee arrangements, and estimates output based on the total tasks completed as compared to the total tasks required for each contract. Input-based estimates are utilized for services that involve general consultations with contractual billing arrangements based on time and materials, utilizing direct labor as the input measure.

The Company also executes arrangements through indirect channel partners in which the channel partners are authorized to market and distribute the Company's software products to end users of the Company's products and services in specified territories. In sales facilitated by channel partners, the channel partner bears the risk of collection from the end-user customer. The Company recognizes revenue from transactions with channel partners when the channel partner submits a purchase commitment, collectability from the channel partner is probable, and the performance obligation is met, at a point in time or over time as appropriate, provided that all other revenue recognition criteria are satisfied. Revenue from channel partner transactions is the amount remitted to the Company by the channel partners. This amount includes a fee for PCS that is compensation for providing technical enhancements and the second level of technical support to the end user, which is recognized over the period that PCS is to be provided. The Company does not offer right of return, product rotation, or price protection to any of its channel partners.

Non-income related taxes collected from customers and remitted to governmental authorities are recorded on the consolidated balance sheets as accounts receivable, net and other accrued expenses and current liabilities. These amounts are reported on a net basis in the consolidated statements of operations and do not impact reported revenues or expenses. Certain hardware revenue is included within software revenue and is recognized when all revenue recognition criteria stated above are met, which is generally when the products are delivered to end customers.

Significant judgments

Software revenue

The Company’s contracts with customers typically include promises to transfer licenses and services to a customer. Judgment is required to determine if the promises are separate performance obligations within the context of the arrangement, and if so, the allocation of the transaction price to each performance obligation. The Company’s determination of standalone selling price for performance obligations is based on the midpoint of the range of historical observable prices for goods and services sold separately. In addition, the Company estimates the standalone selling price for certain performance obligations where observable prices are not directly available or a significant portion of historical prices are not within the range. In instances where standalone selling price was not determined based on the range of historical observable prices for goods and services sold separately, the Company used an adjusted market assessment approach to estimate the standalone selling price. In such cases the Company has considered market conditions and other observable inputs, such as internal price lists, peer data, and industry data for a similar or identical product. The Company estimates standalone selling price at contract inception considering all information that is reasonably available and is based on the amount of consideration for which the Company expects to be entitled in exchange for transferring the promised good or service to the customer. The corresponding revenues are recognized as the related performance obligations are satisfied.

The Company’s contracts do not include a significant financing component requiring adjustment to the transaction price. Payment terms vary by contract type; however, arrangements typically stipulate a requirement for the customer to pay within 30 days.

The Company rarely enters into agreements to modify previously executed contracts, which constitute contract modifications. The Company assesses each of these contract modifications to determine (i) if the additional products and services are distinct from the products and services in the original arrangement; and (ii) if the amount of consideration expected for the added products and services reflects the stand-alone selling price of those products and services, as adjusted for contract-specific circumstances. A contract modification meeting both criteria is accounted for as a separate contract. A contract modification not meeting both criteria is considered a change to the original contract and is accounted for on either (i) a prospective basis as a termination of the existing contract and the creation of a new contract; or (ii) a cumulative catch-up basis. Generally, the Company’s contract modifications meet both criteria and are accounted for as a separate contract, as adjusted for contract-specific circumstances.

Software related services revenue

Consulting services from product design and development projects are considered distinct performance obligations and are provided to customers on a time-and-materials (“T&M”) or fixed-price basis. Altair recognizes software services revenue for T&M contracts based upon hours worked and contractually agreed upon hourly rates using the input method. Revenue from fixed-price engagements is recognized using the output method based on the ratio of costs incurred, to the total estimated project costs.

Client engineering services and Other revenue

Client engineering services revenue are derived from professional services for staffing primarily representing engineers and data scientists located at a customer site. These professional services are considered distinct performance obligations and are provided to customers on a T&M basis. The Company recognizes this revenue for T&M contracts based upon hours worked and contractually agreed upon hourly rates using the input method. No significant judgments were made for revenue recognition within Other revenue.

Disaggregation of revenue

The Company disaggregates its software revenue by type of performance obligation and timing of revenue recognition as follows (in thousands):

	Three Months Ended June 30,				Six Months Ended June 30,
	2020		2019		2020		2019
Software revenue:
Term licenses	$	43,260	$	45,974	$	112,641	$	111,031
Perpetual licenses		7,758		10,679		15,920		22,243

Total software revenue	$	81,833	$	84,408	$	190,276	$	187,699

The Company derived approximately 10% of its total revenue through indirect sales channels for the six months ended June 30, 2020 and 2019.

Software related services revenue, client engineering services revenue, and other revenue were categorized based on the nature and timing of revenue and cash flows.

Costs to obtain a contract

The Company pays commissions for new software product and PCS sales as well as for renewals of existing software and PCS contracts. Commissions paid to obtain renewal contracts are not commensurate with the commissions paid for new product sales and therefore, a portion of the commissions paid for new contracts relate to future renewals.

The Company accounts for new product sales commissions using a portfolio approach and allocates the cost of commissions in proportion to the allocation of transaction price of license and PCS performance obligations. Commissions allocated to the license and license renewal components are expensed at the time the license revenue is recognized. Commissions allocated to PCS are capitalized and amortized on a straight-line basis over a period of four years, reflecting the Company’s estimate of the expected period that it will benefit from those commissions. As of June 30, 2020, and December 31, 2019, capitalized costs to obtain a contract were $3.0 million and $2.3 million, respectively, recorded in prepaid and other current assets, and $0.8 million and $0.8 million, respectively, recorded in other long-term assets. Amortization expense was $1.0 million and $1.6 million for the three and six months ended June 30, 2020, respectively, and $1.2 million and $2.2 million for the three and six months ended June 30, 2019, respectively. Amortization expense was included in sales and marketing expense in the Company’s consolidated statement of operations.

Contract assets

At June 30, 2020 and December 31, 2019, contract assets were $5.6 million and $4.5 million, respectively, recorded in accounts receivable, and $2.3 million and $2.7 million, respectively, recorded in prepaid expenses and other current assets.

Deferred revenue

Deferred revenue consists of billings made or payments received in advance of revenue recognition from software license, PCS and professional services agreements. The timing of revenue recognition may differ from the timing of billings to customers. Payment terms vary by the type and location of customer and the products or services offered. The term between invoicing and when payment is due is not significant. The Company generally invoices its customers annually for the forthcoming year of software licenses, and more frequently for other products and services. Accordingly, the Company’s deferred revenue balance does not include revenue for future years of multiple year non-cancellable contracts that have not yet been billed.

Approximately $53.7 million of revenue recognized during the six months ended June 30, 2020, was included in the deferred revenue balances at the beginning of the year. Revenue allocated to remaining performance obligations represents contracted revenue that has not yet been recognized, which includes deferred revenue and amounts that will be invoiced and recognized as revenue in future periods. Contracted revenue not yet recognized was $117.9 million as of June 30, 2020, of which the Company expects to recognize approximately 82% of the revenue over the next 12 months and the remainder thereafter.

The Company continues to monitor the significant global economic uncertainty as a result of COVID-19 to assess the outlook for demand for its products and the impact on its business. Based on the Company’s interim impairment assessment, there were no indicators of impairment identified during the second quarter of 2020. Notwithstanding this conclusion, if business conditions were to deteriorate in a significant manner or for an extended duration, the likelihood of impairment would increase, and the Company would again assess whether events or changes in circumstances indicate that an asset impairment that is more likely than not exists. Specifically, certain non-amortizing intangible assets from recent acquisitions valued on the basis of short-term forecasts of revenue will be re-assessed for indicators of impairment and it is possible that an impairment charge will be reflected in the future should COVID-19 business conditions worsen or extend substantially in duration.

The allocation of fair value of purchase consideration of the Company’s 2019 acquisitions was finalized in the first quarter of 2020, and there were no material changes to the fair value of assets acquired and liabilities assumed, as previously reported.

Convertible senior notes

In June 2019, the Company issued $230.0 million aggregate principal amount of 0.25% convertible senior notes due in 2024 (the "Convertible Notes"), which includes the underwriters’ exercise in full of their option to purchase an additional $30.0 million principal amount of the Convertible Notes, in a public offering. The net proceeds from the issuance of the Convertible Notes were $221.9 million after deducting the underwriting discounts and commissions and estimated issuance costs.

The Company entered into a First Supplemental Indenture relating to the issuance by the Company of the Convertible Notes (the “Supplemental Indenture”) supplementing the Indenture, dated June 10, 2019 (the “Base Indenture,” and together with the Supplemental Indenture, the “Indenture”), by and between the Company and U.S. Bank National Association, as trustee (the “Trustee”). The Indenture includes customary covenants and sets forth certain events of default after which the Convertible Notes may be declared immediately due and payable and sets forth certain types of bankruptcy or insolvency events of default involving the Company after which the Convertible Notes become automatically due and payable. The Convertible Notes are senior unsecured obligations of the Company.

The Convertible Notes bear interest at a rate of 0.25% per year, payable semi-annually in arrears on June 1 and December 1 of each year, commencing December 1, 2019. The Convertible Notes will mature on June 1, 2024, unless, earlier repurchased or redeemed by the Company or converted pursuant to their terms.

The Convertible Notes have an initial conversion rate of 21.5049 shares of the Company's Class A common stock per $1,000 principal amount of Convertible Notes, which is equivalent to an initial conversion price of approximately $46.50 per share of its Class A common stock. The conversion rate will be subject to adjustment upon the occurrence of certain events specified in the Indenture but will not be adjusted for any accrued and unpaid interest. In addition, upon the occurrence of a make whole fundamental change or a redemption period (each as defined in the Indenture), the Company will, in certain circumstances, increase the conversion rate by a specified number of additional shares for a holder who elects to convert its Convertible Notes in connection with such make whole fundamental change or during the relevant redemption period.

Holders of the Convertible Notes may convert all or any portion of their Convertible Notes at any time prior to the close of business on December 1, 2023, in integral multiples of $1,000 principal amount, only under the following circumstances:

• During any calendar quarter commencing after the calendar quarter ending on September 30, 2019 (and only during such calendar quarter), if the last reported sale price of the Class A Common Stock for at least 20 trading days (whether or not consecutive) during a period of 30 consecutive trading days ending on, and including, the last trading day of the immediately preceding calendar quarter is greater than or equal to 130% of the conversion price on each applicable trading day;

• During the five business day period after any five consecutive trading day period (the “measurement period”) in which the trading price (as defined in the Indenture) per $1,000 principal amount of Convertible Notes for each trading day of the measurement period was less than 98% of the product of the last reported sale price of the Class A Common Stock and the conversion rate on each such trading day;

• If the Company calls any or all of the Convertible Notes for redemption (which the Company may not do prior to June 6, 2022), at any time prior to the close of business on the scheduled trading day immediately preceding the redemption date; or

• Upon the occurrence of specified corporate events.

On or after December 1, 2023 until the close of business on the business day immediately preceding the maturity date, holders may convert their Convertible Notes at any time, regardless of the foregoing circumstances. Upon conversion, the Company may satisfy its conversion obligation by paying and/or delivering, as the case may be, cash, shares of Class A Common Stock or a combination of cash and shares of the Class A Common Stock, at the Company’s election, in the manner and subject to the terms and conditions provided in the Indenture.

During the quarter ended June 30, 2020, the conditions allowing holders of the Convertible Notes to convert were not met. Therefore, the Convertible Notes were classified as long-term debt on the consolidated balance sheet as of June 30, 2020.

As of June 30, 2020, the “if converted value” did not exceed the principal amount of the Convertible Notes.

The Company accounts for the Convertible Notes as separate liability and equity components. The carrying amount of the liability component of the Convertible Notes was calculated by measuring the fair value of similar debt instruments that do not have an associated convertible feature. The carrying amount of the equity component representing the conversion option was determined by deducting the fair value of the liability component from the par value of the Convertible Notes. The difference between the principal amount of the Convertible Notes and the liability component, equal to $51.8 million (the “debt discount”), is amortized to interest expense over the term of the Convertible Notes using the effective interest method. The equity component is not remeasured as long as it continues to meet the conditions for equity classification.

The Company allocated issuance costs related to the issuance of the Convertible Notes to the liability and equity components using the same proportions as the initial carrying value of the Convertible Notes. Issuance costs attributable to the liability component are being amortized to interest expense using the effective interest method over the term of the Convertible Notes. Issuance costs attributable to the equity component are included with the equity component in stockholders’ equity.

The net carrying value of the liability component of the Convertible Notes was as follows (in thousands):

	June 30,		December 31,
	2020		2019
Principal	$	230,000	$	230,000

Credit agreement

Revolving credit facility

The Company has a $150.0 million credit facility with a maturity date of December 15, 2023 (“2019 Amended Credit Agreement”). The 2019 Amended Credit Agreement provides for an accordion feature that allows the Company to expand the size of the revolving line of credit by an additional $50.0 million, subject to certain conditions, by obtaining additional commitments from the existing lenders or by causing a person acceptable to the administrative agent to become a lender (in each case subject to the terms and conditions set forth in the 2019 Amended Credit Agreement).

As of June 30, 2020, the Company had no outstanding borrowings under the 2019 Amended Credit Agreement and there was $150.0 million available for future borrowing. The 2019 Amended Credit Agreement is available for general corporate purposes, including working capital, capital expenditures, and permitted acquisitions.

Borrowings under the 2019 Amended Credit Agreement bear interest at a rate per annum equal to an agreed upon applicable margin plus, at the Company’s option, either the Alternate Base Rate (defined as the greatest of (1) the Prime Rate (as defined in the 2019 Amended Credit Agreement) in effect on such day, (2) the Federal Funds Effective Rate (as defined in the 2019 Amended Credit Agreement) in effect on such day plus 1/2 of 1.00% or (3) the Adjusted LIBO Rate (as defined in the 2019 Amended Credit Agreement) for a one month interest period on such day (or if such day is not a business day, the immediately preceding business day) plus 1.00%) or the Adjusted LIBO Rate. The applicable margin for borrowings under the 2019 Amended Credit Agreement is based on the Company’s most recently tested consolidated total net leverage ratio and will vary from (a) in the case of Eurodollar loans, 1.25% to 2.00%, and (b) in the case of ABR loans and swingline loans, 0.25% to 1.00%. The Company pays a commitment fee (based on the Company’s most recently tested consolidated total senior secured net leverage ratio) ranging from 0.15% to 0.30% on the unused portion of the 2019 Amended Credit Agreement.

• Senior Secured Leverage Ratio: On the last day of each fiscal quarter, the Company on a consolidated basis will not permit the ratio of total indebtedness secured by a lien (net of unrestricted domestic cash in excess of $20.0 million) to EBITDA, as such terms are defined in the 2019 Amended Credit Agreement, for the rolling four quarter period ending on such date to be greater than 3.00 to 1.00 as of the last day of any such fiscal quarter.

• Consolidated Interest Coverage Ratio: On the last day of each fiscal quarter, the Company on a consolidated basis will not permit the ratio of (x) EBITDA to (y) cash Consolidated Interest Expense, as such terms are defined in the 2019 Amended Credit Agreement, in each case for the rolling four quarter period ending on such date, to be less than 3.00 to 1.00 as of the last day of any such fiscal quarter.

At June 30, 2020, the Company was in compliance with all the above financial covenants.

Fair Value Disclosures [Abstract]

Fair Value Measurements

8. Fair value measurements

The accounting guidance for fair value, among other things, defines fair value, establishes a consistent framework for measuring fair value and expands disclosure for each major asset and liability category measured at fair value on either a recurring or nonrecurring basis. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability (an exit price) in an orderly transaction between market participants at the reporting date. The framework for measuring fair value consists of a three-level valuation hierarchy that prioritizes the inputs to valuation techniques used to measure fair value based upon whether such inputs are observable or unobservable. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect market assumptions made by the reporting entity. The three-level hierarchy for the inputs to valuation techniques is briefly summarized as follows:

Level 1 – Quoted prices in active markets for identical assets and liabilities at the measurement date;

Level 2 – Observable inputs, other than the quoted prices in active markets, that are observable either directly or indirectly; and

Level 3 – Unobservable inputs in which there is little or no market data, which require the reporting entity to develop its own assumptions.

An asset’s or liability’s fair value measurement level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement. Valuation techniques used need to maximize the use of observable inputs and minimize the use of unobservable inputs.

The carrying value of cash and cash equivalents, accounts receivable and accounts payable approximate fair value due to their short maturities. Interest on the Company’s line of credit is at a variable rate, and as such the debt obligation outstanding approximates fair value.

The carrying value of the Company’s Convertible Notes are at face value less unamortized debt discount and issuance costs. The estimated fair values of the Convertible Notes, which the Company has classified as Level 2 financial instruments, were determined based on quoted bid prices of the Convertible Notes on the last trading day of each reporting period. At June 30, 2020, the fair value of the Convertible Notes was $242.5 million and is presented for required disclosure purposes only. For further information on the Convertible Notes, see Note 6. – Debt.

Earnings Per Share [Abstract]

Net (Loss) Income Per Share

9. Net (loss) income per share

Basic (loss) income per share attributable to common stockholders is computed using the weighted average number of shares of common stock outstanding for the period, excluding stock options and restricted stock units (“RSUs”). Diluted (loss) income per share attributable to common stockholders is based upon the weighted average number of shares of common stock outstanding for the period and potentially dilutive common shares, including the effect of stock options and RSUs under the treasury stock method. The following table sets forth the computation of the numerators and denominators used in the basic and diluted (loss) income per share amounts (in thousands, except per share data):

	Three Months Ended June 30,						Six Months Ended June 30,
	2020			2019			2020			2019
Numerator:
Net (loss) income	$	(10,223	)	$	(3,120	)	$	(4,193	)	$	9,899
Denominator:
Denominator for basic (loss) income per share— weighted average shares		72,999			71,373			72,811			71,081
Effect of dilutive securities, stock options and RSUs		—			—			—			5,936
Denominator for dilutive (loss) income per share		72,999			71,373			72,811			77,017
Net (loss) income per share attributable to common   stockholders, basic	$	(0.14	)	$	(0.04	)	$	(0.06	)	$	0.14
Net (loss) income per share attributable to common   stockholders, diluted	$	(0.14	)	$	(0.04	)	$	(0.06	)	$	0.13

The computation of diluted (loss) income per share does not include shares that are anti-dilutive under the treasury stock method because their exercise prices are higher than the average fair value of the Company’s stock during the period or due to a net loss in the period. For each of the three and six months ended June 30, 2020, there were 4.5 million anti-dilutive stock options excluded from the computation of (loss) income per share. For the three months ended June 30, 2019, there were 5.6 million anti-dilutive stock options excluded from the computation of (loss) income per share. For the six months ended June 30, 2019, there were no anti-dilutive shares excluded from the computation of income per share.

The Company expects to settle the principal amount of the Convertible Notes in cash, and therefore, the Company uses the treasury stock method for calculating any potential dilutive effect of the Conversion Option on diluted net income per share, if applicable. The Conversion Option will have a dilutive impact on net income per share of common stock when the average market price of the Company’s Class A common stock for a given period exceeds the conversion price of the Convertible Notes of $46.50 per share. During the three and six months ended June 30, 2020, the Company's weighted average common stock price was below the conversion price of the Convertible Notes.

2001 stock-based compensation plans

Nonqualified stock option plan

In 2001, the Company established the Nonqualified Stock Option Plan (“NSO Plan”) under which 3,246,119 stock options with an exercise price of $0.000025 remain outstanding at June 30, 2020. The NSO Plan was terminated in 2003. Stock options under the NSO plan were immediately vested and have a contractual term of 35 years from the date of grant. The outstanding awards will continue to be governed by their existing terms under the NSO Plan. The NSO Plan is accounted for as an equity plan.

The following table summarizes the stock option activity under the NSO Plan for the period:

	Number of options			Weighted average exercise price per share		Weighted average remaining contractual term (years)		Aggregate intrinsic value (in millions)
Outstanding at January 1, 2020		3,557,436		$	0.000025		17.0	$	127.8
Exercised		(311,317	)	$	0.000025
Forfeited		—			—
Outstanding and exercisable at June 30, 2020		3,246,119		$	0.000025		16.5	$	129.0

The total intrinsic value of the NSO Plan stock options exercised during the six months ended June 30, 2020, was $10.4 million.

Incentive and nonqualified stock-based plan

Also in 2001, the Company established the Incentive and Nonqualified Stock-based Plan (“ISO Plan”) which was terminated in 2011 and was authorized to issue nonqualified stock options (“NQSO”) and incentive stock options (“ISO”) covering 11,153,872 shares of Class A common stock. The NQSO grants could be issued at less than the fair market value at date of grant under the terms of the ISO Plan, while ISO grants were issued at a price equal to or greater than the fair market value at date of grant. Options generally vested over a two to three-year period. All options have a contractual term of ten years from the date of grant.

The following table summarizes the stock option activity under the 2001 stock-based compensation plans for the period:

	Number of options			Weighted average exercise price per share		Weighted average remaining contractual term (years)		Aggregate intrinsic value (in millions)
Outstanding at January 1, 2020		103,000		$	0.64		1.0	$	3.6

Forfeited		—			—
Outstanding and exercisable at June 30, 2020		37,500		$	0.64		0.5	$	1.5

The total intrinsic value of the ISO Plan stock options exercised during the six months ended June 30, 2020, was $1.9 million.

2012 stock-based compensation plans

During 2012, the Company established the 2012 Incentive and Nonqualified Stock Option Plan (“2012 Plan”) which permits the issuance of 5,200,000 shares of Class A common stock for the grant of nonqualified stock options and incentive stock options for management, other employees, and board members of the Company. The options are issued at a price equal to or greater than fair market value at date of grant. All options have a contractual term of 10 years from date of grant.

The 2012 Plan is accounted for as an equity plan. For those options expected to vest, compensation expense is recognized on a straight-line basis over a four-year period, the total requisite service period of the awards. Total compensation cost related to nonvested awards not yet recognized as of June 30, 2020, totaled $0.3 million, and is expected to be recognized over a weighted average period of 0.9 years.

The following table summarizes the stock option activity under the 2012 Plan for the period:

	Number of options			Weighted average exercise price per share		Weighted average remaining contractual term (years)		Aggregate intrinsic value (in millions)
Outstanding at January 1, 2020		1,183,817		$	4.23		6.1

The total intrinsic value of the 2012 Plan stock options exercised during the six months ended June 30, 2020, was $3.9 million.

2017 stock-based compensation plan

In 2017, the Company’s board of directors adopted the 2017 Equity Incentive Plan (“2017 Plan”), which was approved by the Company’s stockholders. The 2017 Plan provides for the grant of incentive stock options to the Company’s employees and any parent and subsidiary corporations’ employees, and for the grant of nonstatutory stock options, stock appreciation rights, restricted stock, restricted stock units, performance units, performance shares, other cash-based awards and other stock-based awards to the Company’s employees, directors and consultants and the Company’s parent, subsidiary, and affiliate corporations’ employees and consultants. As of January 1, 2020, the 2017 Plan had 10,277,034 authorized shares of the Company’s Class A common stock reserved for issuance.

The following table summarizes the restricted stock units, or RSUs, awarded under the 2017 Plan for the period:

	Number of RSUs
Outstanding at January 1, 2020		781,301
Granted		565,723
Vested		(193,684	)
Forfeited		(16,313	)
Outstanding at June 30, 2020		1,137,027

The weighted average grant date fair value of the RSUs was $33.73 and the RSUs generally vest in four equal annual installments. Total compensation cost related to nonvested awards not yet recognized as of June 30, 2020, totaled $62.9 million, and is expected to be recognized over a weighted average period of approximately three years.

The following table summarizes the stock option activity under the 2017 Plan for the period:

	Number of options			Weighted average exercise price per share		Weighted average remaining contractual term (years)		Aggregate intrinsic value (in millions)
Outstanding at January 1, 2020		20,000		$	38.11		9.2

Exercisable at June 30, 2020		5,158		$	37.84		8.5	$	0.01

In addition to the stock options granted above, the Company expects to grant an additional 2.0 million stock options on December 2, 2020, with an exercise price reflecting the fair value on that date. Recipients of the December 2, 2020, deferred stock option award must be employed on that date in order to receive the grant. The Company has concluded that the grant date for this deferred award is December 2, 2020, and this grant will not be reflected in the table above until the fourth quarter of 2020.

The Company measures the fair value of its equity awards on the date of grant using the Black-Scholes option pricing model. This valuation model requires the Company to make certain estimates and assumptions, including assumptions related to the expected price volatility of the Company’s stock, the period under which the options will be outstanding, the rate of return on risk-free investments, and the expected dividend yield for the Company’s stock.

The fair values of the Company’s stock options granted during the six months ended June 30, 2020, were estimated using the following assumptions:

	2020 grants
Weighted average grant date fair value per share	$ 38.11 - 39.82
Expected volatility	35 - 42%
Expected term (in years)	6.25
Risk-free interest rate	0.46 - 1.80%
Expected dividend yield		0	%

These assumptions and estimates are as follows:

• Fair Value of Common Stock. The Company used the publicly quoted price as reported on the Nasdaq Global Select Market as the fair value of its common stock.

• Expected Term. The Company used the simplified method to determine the expected term.

• Risk-Free Interest Rate. The Company based the risk-free interest rate on U.S. Treasury zero-coupon yield curves with a remaining term equal to the expected term of the option.

• Expected Volatility. As the Company does not have an extensive trading history for its common stock, the expected volatility was derived using the historical volatility of the returns of comparable publicly traded companies combined with the brief trading history of the Company’s common stock.

Income Taxes

Income Tax Disclosure [Abstract]

Income Taxes

11. Income taxes

At the end of each interim period, the Company makes its best estimate of the annual expected effective income tax rate and applies that rate to its ordinary year-to-date income (loss) before income taxes. The income tax provision or benefit related to unusual or infrequent items, if applicable, that will be separately reported or reported net of their related tax effects are individually computed and recognized in the interim period in which those items occur. In addition, the effect of changes in enacted tax laws or rates, tax status, judgment on the realizability of a beginning-of-the-year deferred tax asset in future years or income tax contingencies is recognized in the interim period in which the change occurs.

The computation of the annual expected effective income tax rate at each interim period requires certain estimates and assumptions including, but not limited to, the expected income (loss) before income taxes for the year, projections of the proportion of income (and/or loss) earned and taxed in respective tax jurisdictions, including applicable foreign taxes withheld at the source, permanent and temporary differences, and the likelihood of the realizability of deferred tax assets generated in the current year. Jurisdictions with a projected loss for the year or a year-to-date loss for which no tax benefit can be recognized due to a valuation allowance are excluded from the estimated annual effective tax rate. The impact of such an exclusion could result in a higher or lower effective tax rate during a particular quarter, based upon the composition and timing of actual earnings compared to annual projections. The estimates used to compute the provision or benefit for income taxes may change as new events occur, additional information is obtained or the Company’s tax environment changes. To the extent that the expected annual effective income tax rate changes, the effect of the change on prior interim periods is included in the income tax provision in the period in which the change in estimate occurs.

The Company’s income tax expense and effective tax rate for the three and six months ended June 30, 2020 and 2019, were as follows (in thousands, except percentages):

	Three Months Ended June 30,						Six Months Ended June 30,
	2020			2019			2020			2019
Income tax expense	$	2,768		$	(167	)	$	7,420		$	3,921
Effective tax rate		(37	%)		5	%		230	%		28	%

The tax rate is affected by the Company being a U.S. resident taxpayer, the tax rates in the U.S. and other jurisdictions in which the Company operates, the relative amount of income earned by jurisdiction and the relative amount of losses or income for which no benefit or expense is recognized due to a valuation allowance. The Company’s effective tax rate for the six months ended June 30, 2020 and 2019, also includes net discrete expense of $3.7 million and net discrete benefit of $1.2 million, respectively, primarily related to changes in reserves, changes in accruals for unremitted earnings and other adjustments.

On March 27, 2020, the Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”) was enacted in response to COVID-19. The CARES Act, among other things, permits NOL carryovers and carrybacks to offset 100% of taxable income for taxable years beginning before 2021. In addition, the CARES Act allows NOLs incurred in 2018, 2019, and 2020 to be carried back to each of the five preceding taxable years to generate a refund of previously paid income taxes. The CARES Act also provides a temporary relaxation of the limitation (reflected in section 163(j) of the Internal Revenue Code) on business interest expense deductions to 50% of adjusted taxable income for tax years beginning in 2019 and 2020, and an election to use 2019 adjusted taxable income for tax years beginning in 2020. The Company is currently evaluating the impact of the CARES Act, but at present does not expect that the NOL carryback provision of the CARES Act would result in a material tax benefit. The Company also does not expect the relaxation of section 163(j) provisions to have a material tax benefit since the Company is expected to be in a net interest income position. In addition, the Company has evaluated the COVID-19 related legislation globally and does not expect the legislation to have a material tax impact on the Company. Further, on July 23, 2020, the Department of Treasury published final regulations under the global intangible low-taxed income and Subpart F provisions of the Internal Revenue Code regarding the treatment of income that is subject to a high rate of foreign tax (“high-tax exclusion”). These regulations, among other things, permit U.S. shareholders of foreign corporations to make an election for a controlled foreign corporation to exclude from subpart F income any item of income received by the controlled foreign corporation if that income is subject to an effective tax rate greater than 90% of the maximum U.S. corporate income tax rate of 21%. The Company is in the process of evaluating the impact of these regulations and has not determined if an election should be made to avail the high-tax exclusion for tax years beginning January 1, 2018 or later.

Swedish Tax Litigation

The Swedish Tax Authorities, or STA, assessed tax (net of utilization of tax attributes), penalties and interest in the amount of $6.2 million related to the acquisition of Panopticon AB by Datawatch Corporation, in 2013 for the years 2013, 2014 and 2015. The STA, upon auditing the acquisition transaction, reached a conclusion that post acquisition, certain assets were removed from Sweden, triggering the tax obligation. The STA is also of the opinion that some services related to product development provided to the new parent company in the U.S. were performed by Panopticon AB at a price below market price triggering tax obligations. Datawatch contested the findings by the STA throughout the audit process including contesting the STA position in the first level of administrative courts. On May 29, 2019, the Administrative Court issued its ruling in favor of Datawatch AB. On July 4, 2019, the STA filed an appeal of the Administrative Court ruling with the Administrative Court of Appeal in Stockholm, effectively continuing to assert that the assessments are in fact appropriate. After relevant submissions by the Company and the STA, the Court of Appeals held a hearing on February 20, 2020. On March 27, 2020, the Court of Appeals issued its finding in favor of the STA. Pursuant to requirements in Sweden, the Company paid the assessed tax, penalties and interest on April 24, 2020. The Company, in accordance with its right to appeal the ruling to the Administrative Supreme Court of Sweden, filed an appeal of the Court of Appeals ruling citing specific grounds for reconsideration. Whether the Administrative Supreme Court will agree to hear the appeal is unknown at present. Further, even if the Administrative Supreme Court agrees to hear the appeal, there is no assurance that it will rule in favor of the Company.

Other legal proceedings

From time to time, the Company may be subject to legal proceedings and claims in the ordinary course of business. The Company has received, and may in the future continue to receive, claims from third parties asserting, among other things, infringement of their intellectual property rights. Future litigation may be necessary to defend the Company, its partners and its customers by determining the scope, enforceability and validity of third party proprietary rights, or to establish and enforce the Company’s proprietary rights. The results of any current or future litigation cannot be predicted with certainty and regardless of the outcome, litigation can have an adverse impact on the Company because of defense and settlement costs, diversion of management resources and other factors.

Segment Reporting [Abstract]

Segment Information

14. Segment information

The Company defines its operating segments as components of its business where separate financial information is available and used by the chief operating decision maker (“CODM”) in deciding how to allocate resources to its segments and in assessing performance. The Company’s CODM is its Chief Executive Officer.

The Company has identified two reportable segments for financial reporting purposes: Software and Client Engineering Services, or “CES”. The primary measure of segment operating performance is Adjusted EBITDA, which is defined as net income (loss) adjusted for income tax expense (benefit), interest expense, interest income and other, depreciation and amortization, stock-based compensation expense, restructuring charges, asset impairment charges and other special items as determined by management. Adjusted EBITDA includes an allocation of corporate headquarters costs.

The Software reportable segment derives revenue from the sale and lease of licenses for software products focused on the development and application of simulation technology to synthesize and optimize designs, processes and decisions for improved business performance. The Software segment also derives revenue from software support, upgrades, training and consulting services focused on product design and development expertise and analysis support from the component level up to complete product engineering at any stage of the lifecycle. To a much lesser extent, the Software segment also includes revenue from the sale of hardware products, primarily as a result of prior business acquisitions.

The Client Engineering Services reportable segment provides support to its customers with long-term ongoing product design and development expertise in its market segments of Solvers & Optimization, Modeling & Visualization, Industrial and Concept Design, and high performance computing. The Company hires simulation specialists, industrial designers, design engineers, materials experts, development and test specialists, manufacturing engineers and information technology specialists for placement at customer sites for specific customer-directed assignments.

The “All other” represents innovative services and products, including toggled^®, the Company’s LED lighting business. toggled^® is focused on developing and selling next-generation solid state lighting technology along with communication and control protocols based on intellectual property for the direct replacement of fluorescent light tubes with LED lamps, and for control of LED lighting. Other businesses combined within Other include the Company’s WEYV business, which ceased operations in the third quarter of 2019, and potential services and product concepts that are still in their development stages.

Inter-segment sales are not significant for any period presented. The CODM does not review asset information by segment when assessing performance, therefore, no asset information is provided for reportable segments. The accounting policies of the segments are the same as those described in Note 1 – Organization and summary of significant accounting policies.

Organization Consolidation And Presentation Of Financial Statements [Abstract]

Basis of Presentation

Basis of presentation

The accompanying unaudited consolidated financial statements have been prepared in accordance with United States generally accepted accounting principles (“GAAP”) and applicable rules and regulations of the Securities and Exchange Commission (“SEC”) regarding interim financial information.  Accordingly, the accompanying statements do not include all the information and notes required by GAAP for complete financial statements. The accompanying unaudited consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements (and notes thereto) for the year ended December 31, 2019, included in the most recent Annual Report on Form 10-K filed with the SEC. In the opinion of management, all adjustments considered necessary for a fair presentation of the financial statements have been included, and all adjustments are of a normal and recurring nature. The preparation of the financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, and disclosures of contingent assets and liabilities at the date of the financial statements and reported amounts of revenue and expenses during the reporting periods. Considerable judgment is often involved in making these determinations; use of different assumptions could result in significantly different results. Management believes its assumptions and estimates are reasonable and appropriate. However, actual results may differ from those estimates.  In addition, the results of operations for the three and six months ended June 30, 2020, are not necessarily indicative of the results that may be expected for any future period.

Use of Estimates

Use of estimates

The preparation of the consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and reported amounts of revenue and expenses during the reporting periods. On an ongoing basis, management evaluates its significant estimates including the stand alone selling price, or SSP, for each distinct performance obligation included in customer contracts with multiple performance obligations, valuation of acquired intangible assets in business combinations, the incremental borrowing rate used in the valuation of lease liabilities, the determination of the period of benefit for capitalized costs to obtain a contract, fair value of convertible senior notes, provision for credit loss, tax valuation allowances, liabilities for uncertain tax provisions, impairment of goodwill and intangible assets, retirement obligations, useful lives of intangible assets, revenue for fixed price contracts, and stock-based compensation. Actual results could differ from those estimates.

COVID-19

COVID-19

In March 2020, The World Health Organization declared the outbreak of COVID-19 a pandemic, and a public health emergency of international concern. The global spread of COVID-19 created significant volatility and uncertainty. Such conditions are expected to continue to persist. To limit the spread of COVID-19, governments have taken various actions from time to time including the issuance of travel restrictions, complete or partial prohibitions of non-essential activities, restrictions or shutdowns of non-essential businesses, stay-at-home orders and social distancing guidelines. Some of these actions have varied from initial responses, pivoting between full or complete to partial or limited restrictions depending upon local or regional conditions. Accordingly, many businesses have adjusted to these actions by reducing or suspending operating or other activities. This has negatively impacted several of the markets the Company serves, including the automotive and aerospace markets.

The Company continues to robustly engage with its customers, primarily virtually. While the Company believes this active level of engagement may mitigate potential and evolving negative impacts from COVID-19, existing and potential customers may choose to reduce or delay technology spending in response to COVID-19, or attempt to renegotiate contracts and obtain concessions, which may materially and negatively impact the Company’s operating results, financial condition and new business. In certain cases, the Company has provided longer than normal payment terms to certain of its customers; however, the terms are less than one year, and the Company does not expect this to materially affect its consolidated financial statements. COVID-19’s

impact on some of the Company’s customers has primarily contributed to the decrease in revenue for software related and client engineering services. The Company’s software product revenue has been affected by elongated sales cycles for some of its customers along with greater challenges in securing new and expansion business. The Company is unable to accurately predict the full impact that COVID-19 will have due to numerous uncertainties, including the full scope of the disease, the duration of the initial outbreak or the number and intensity of subsequent waves of infections, actions that may be taken by governmental authorities, the impact to the businesses of the Company’s customers and partners, and the development of treatments and vaccines. Even after the COVID-19 pandemic has subsided, the Company may experience material adverse impacts to its business as a result of any economic recession or depression that has occurred or may occur in the future. The Company will continue to evaluate the nature and extent of the impact to its business, consolidated results of operations, and financial condition.

Cash, Cash Equivalents and Restricted Cash

Cash, cash equivalents and restricted cash

The Company considers all highly liquid investments with original or remaining maturities of 90 days or less at the date of purchase to be cash equivalents. Cash and cash equivalents are recorded at cost, which approximates fair value. Restricted cash is included in other long-term assets on the consolidated balance sheets. The following table provides a reconciliation of cash, cash equivalents and restricted cash reported in the consolidated balance sheets that sum to the total of the amounts reported in the consolidated statement of cash flows (in thousands):

	June 30, 2020		December 31, 2019
Cash and cash equivalents	$	250,540	$	223,117
Restricted cash included in other long-term assets		386		380
Total cash, cash equivalents, and restricted cash	$	250,926	$	223,497

Restricted cash represents amounts required for a contractual agreement with an insurer for the payment of potential health insurance claims, and term deposits for bank guarantees.

Inventory

Inventory

Inventory consists of finished goods and is stated at the lower of cost and net realizable value. Cost is determined using the first-in, first-out method. Net realizable value is the estimated selling prices in the ordinary course of business, less reasonable predictable costs of completion, disposal and transportation. The valuation of inventory requires management to estimate excess inventory as well as inventory that is not of saleable quality. The determination of obsolete or excess inventory requires management to estimate market conditions and future demand for the Company’s products. Inventory was $2.8 million and $2.4 million at June 30, 2020 and December 31, 2019, respectively, and is included in prepaid expenses and other current assets in the consolidated balance sheets.

Receivable for French R&D Credit

Receivable for French R&D credit

The French government provides a research and development (“R&D”) tax credit known as Credit Impôt Recherche, or CIR, in order to encourage Companies to invest in R&D activities. The tax credit is deductible from French income tax and any excess is carried forward three years. After three years, any unused credit may be reimbursed to the Company by the French government. As of June 30, 2020, the Company had approximately $13.7 million of receivables from the French government related to CIR, of which $2.5 million was recorded in income tax receivable and the remaining $11.2 million was recorded in other long-term assets. As of December 31, 2019, the Company had approximately $12.1 million of receivables from the French government related to CIR, of which $2.5 million was recorded in income tax receivable and the remaining $9.6 million was recorded in other long-term assets. CIR is subject to customary audit by French tax authorities.

Mezzanine Equity

Mezzanine equity

In 2017, the Company issued 200,000 shares of Class A common stock to a third party as partial consideration for the purchase of developed technology. These shares have a put right that can be exercised by the holder five years from date of purchase at $12.50 per share that requires the shares to be recorded at fair value at the issuance date and classified as mezzanine equity in the consolidated balance sheet. The put right option is terminated if the shareholders sell their shares. As of December 31, 2017, the Company concluded that it is no longer probable that the put option will be exercised as the put value is substantially below market value and subsequent adjustment is not required.

During the quarter ended June 30, 2020, the third party holder sold 133,336 shares on the open market and as a result, the issuance value of those shares was reclassified into permanent equity out of mezzanine equity. The remaining 66,664 shares shall remain as mezzanine equity until one of the following three events take place: (1) the shares are sold on the open market; (2) a redemption feature lapses; or (3) there is a modification of the terms of the instrument.

Leases

Leases

The Company determines if an arrangement is a lease at inception. Operating leases are included in operating lease right-of-use (“ROU”) assets, current portion of operating lease liabilities, and operating lease liabilities, net of current portion on the Company’s consolidated balance sheets. Finance leases are included in property and equipment, current portion of long-term debt, and long-term debt, net of current portion on the consolidated balance sheets. The Company did not receive any lease concessions related to COVID-19 that had a material effect on the Company’s consolidated financial statements.

Recent Accounting Guidance

Recent accounting guidance

Accounting standards adopted

Credit Losses – In June 2016, the FASB issued ASU 2016-13, Financial Instruments — Credit Losses (Topic 326):  Measurement of Credit Losses on Financial Instruments. The ASU significantly changes how entities will measure credit losses on most financial assets. The Company adopted ASU 2016-13 effective January 1, 2020 and recorded a cumulative effect adjustment to retained earnings of $0.4 million related to the adoption of ASU 2016-13; prior periods have not been adjusted. Under this new accounting standard, beginning January 1, 2020, an allowance for expected credit losses for groups of billed and unbilled receivables and contract assets that share similar risk characteristics is recorded based on an evaluation of historical loss experience, current conditions, and reasonable and supportable forecasts. Accounts are written off when it becomes apparent that such amounts will not be collected, generally when amounts are past due by greater than one year. Generally, the Company does not require collateral or charge interest on accounts receivable. Accounts receivable were reported net of an allowance for doubtful accounts of $2.4 million and $1.4 million at June 30, 2020 and December 31, 2019, respectively. 

Subsequent to adoption, the Company considered the impact of COVID-19 on its historical credit loss rates and made an adjustment to increase expected credit loss rates. The impact resulting from the increased credit loss rates did not have a material effect on the Company’s consolidated financial statements.

Fair Value – In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework – Changes to the Disclosure Requirements for Fair Value Measurement. This ASU modifies the disclosure requirements for fair value measurements, by removing, modifying, or adding certain disclosures. The Company adopted ASU 2018-13 on January 1, 2020. The adoption of this guidance did not have a material effect on the Company’s consolidated financial statements.

Intangibles – In August 2018, the FASB issued ASU 2018-15, Intangibles – Goodwill and Other – Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That is a Service Contract. This ASU clarifies and aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software. The Company adopted ASU 2018-15 on January 1, 2020, on a prospective basis. The adoption of this guidance did not have a material effect on the Company’s consolidated financial statements.

Accounting standards not yet adopted 

Retirement Benefits – In August 2018, the FASB issued ASU 2018-14, Compensation – Retirement Benefits- Defined Benefit Plans – General (Subtopic 715-20): Disclosure Framework – Changes to the Disclosure Requirements for Defined Benefit Plans. This ASU modifies the disclosure requirements for defined benefit pension or other postretirement plans. The amendments are effective for fiscal years ending after December 15, 2020; early adoption is permitted. The Company is currently evaluating the impact of the new guidance on its consolidated financial statements and related disclosures and does not expect this guidance to have a material effect on its consolidated financial statements.

Income Taxes – In December 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes. This ASU simplifies the accounting for income taxes by removing certain exceptions to the general principles in Topic 740 and improves consistent application of GAAP for other areas of Topic 740 by clarifying and amending existing guidance. The amendments are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2020; early adoption is permitted. The Company is currently evaluating the impact of the new guidance on its consolidated financial statements and related disclosures and does not expect this guidance to have a material effect on its consolidated financial statements.

Reference Rate Reform – In March 2020, the FASB issued ASU 2020-04. Reference Rate Reform (Topic 848) - Facilitation of the Effects of Reference Rate Reform on Financial Reporting. This ASU provides optional expedients and exceptions for applying U.S. GAAP to contract modifications and hedging relationships, subject to meeting certain criteria, that reference LIBOR or another rate that is expected to be discontinued. The amendments in the guidance are effective for all entities as of March 12, 2020 through December 31, 2022. The Company is currently evaluating the impact of this new guidance on its consolidated financial statements and related disclosures and does not expect this guidance to have a material effect on its consolidated financial statements.
