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 leader in computational science and artificial intelligence enabling organizations across broad industry segments to drive smarter decisions in an increasingly connected world. Altair delivers software and cloud solutions in the areas of simulation, high-performance computing (“HPC”), data analytics, and artificial intelligence (“AI”). Altair’s products and services help create a more sustainable future for the planet. 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, 2021, included in the most recent Annual Report on Form 10-K filed with the SEC. 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. Significant accounting policies There have been no material changes to our significant accounting policies as of and for the three months ended March 31, 2022, as compared to the significant accounting policies described in our Annual Report on Form 10-K for the year ended December 31, 2021.

Accounting Changes And Error Corrections [Abstract]
Recent Accounting Guidance	2 . Accounting standards adopted Debt – In August 2020, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2020-06, This ASU simplifies the accounting for convertible instruments by eliminating certain separation models. Under ASU 2020 - 06 , a convertible debt instrument will generally be reported as a single liability at its amortized cost with no separate accounting for embedded conversion features. The update also requires the if-converted method to be used for convertible instruments and the effect of potential share settlement be included in the diluted earnings per share calculation when an instrument may be settled in cash or shares. The Company adopted ASU 2020-06 effective as of January 1, 2022, using the modified retrospective approach. Adoption of the new standard resulted in a decrease to accumulated deficit of $23.9 million, a decrease to additional paid-in capital of $50.0 million, and an increase to convertible senior notes, net of $26.1 million. Interest expense recognized in the current and future periods will be reduced as a result of accounting for the convertible debt instrument as a single liability measured at its amortized cost. Accounting standards not yet adopted Reference Rate Reform – In March 2020, the FASB issued ASU 2020-04. 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 optional and 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. Government Assistance – In November 2021, the FASB issued ASU 2021-10, . This ASU requires certain disclosures about transactions with a government that are accounted for by applying a grant or contribution accounting model by analogy. The amendment requires disclosure of information about the nature of the transactions and the related accounting policy used to account for the transactions, information regarding the line items within the consolidated financial statements that are affected by the transactions, and significant terms and conditions of the transactions. ASU 2021-10 is effective for annual periods beginning after December 15, 2021, with early application permitted. The Company is currently evaluating the effect the adoption of this new guidance will have on its consolidated financial statement disclosures.

Business Combination And Asset Acquisition [Abstract]
Acquisitions	5. Acquisitions 2022 Acquisitions During the three months ended March 31, 2022, the Company completed two business acquisitions that will be accounted for as business combinations under the acquisition method. The operating results of each acquisition have been included in the consolidated financial statements since the respective dates of acquisition. The Company’s transaction costs related to these acquisitions were not material. As of March 31, 2022, the $13.2 million aggregate consideration for these acquisitions was reported in goodwill in the consolidated balance sheet pending fair value allocation. All goodwill is recorded in the Software segment. The Company expects to finalize the valuations as soon as practicable, but not later than one year from the acquisition dates. These acquisitions were not material to the Company’s consolidated financial statements. 2021 Acquisitions World Programming In December 2021, the Company acquired all of the outstanding capital stock of two related privately held companies, World Programming Limited and December 2015 Software Limited (together “World Programming”), from the stockholders named therein, for preliminary aggregate consideration of $73.1 million. The closing consideration of $73.1 million consisted of cash in the amount of $50.0 million, subject to a customary working capital adjustment, and contingent consideration of $23.1 million, including $20.3 million of the Company’s Class A Common Stock (the “Stock Consideration”) and a measurement period adjustment of $2.8 million in the first quarter of 2022. The dates on which the Stock Consideration is issuable and the number of shares issuable on such dates depend primarily on certain aspects of legal proceedings in which World Programming and SAS Institute, Inc. are engaged. For further information on the legal proceedings see Note 13. In addition, per the stock purchase agreement, $29.5 million worth of Class A Common Stock will be issued subject to the continuing employment of certain key employees and are not reflected in aggregate consideration but will be recognized as stock-based compensation over the service period of three years. As of March 31, 2022, Other accrued expenses and current liabilities included $2.8 million of contingent consideration due to employees. The acquisition has been accounted for as a business combination under the acquisition method of accounting, which results in acquired assets and assumed liabilities being measured at their estimated fair value as of the acquisition date. The following table summarizes the preliminary purchase consideration transferred to acquire World Programming and the amounts of identified assets acquired and liabilities assumed at the acquisition date (in thousands): Fair value of consideration transferred $ 73,050 Recognized amounts of identifiable assets acquired and liabilities assumed: Cash 1,895 Accounts receivable 4,859 Other assets 6,085 Property and equipment 2,208 Trade names (4-year life) 300 Developed technology (5-year life) 33,000 Customer relationships (7-year life) 7,000 SAS legal liability (66,596 ) Accounts payable and other liabilities (3,401 ) Deferred revenue (2,737 ) Deferred tax liabilities and other tax reserves (11,406 ) Total net identifiable assets acquired and liabilities assumed (28,793 ) Goodwill (1) $ 101,843 (1) Goodwill is primarily attributable to market synergies expected to arise after the acquisition and is not deductible for tax purposes. All goodwill is recorded The preliminary estimated fair values of assets acquired and liabilities assumed, and identifiable intangible assets may be subject to change as additional information is received. The valuation was complex due to the significant estimation uncertainty in certain assumptions used to determine the fair value of intangible assets acquired and contingent consideration. The primary areas that remain preliminary relate to the fair value of intangible assets acquired, certain tangible assets and liabilities acquired, contingent consideration, income taxes and residual goodwill.

Debt Disclosure [Abstract]
Debt	7 . Debt 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 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 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. Refer to the Company’s consolidated financial statements for the year ended December 31, 2021, for details of the issuance of the Convertible Notes. For at least twenty trading days during the last thirty consecutive trading days in the quarter ended March 31, 2022, the last reported sale price of the Company’s Class A common stock was greater than or equal to 130% of the conversion price of the Convertible Notes. As a result, the Convertible Notes were convertible at the option of the holders and remained classified as current liabilities on the consolidated balance sheet as of March 31, 2022. The Company may settle the Convertible Notes in 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. The Company intends to settle the principal amount of the Convertible Notes in cash and the conversion spread in shares. As of March 31, 2022, the “if converted value” exceeded the principal amount of the Convertible Notes by $88.5 million The net carrying value of the Convertible Notes was as follows (in thousands): March 31, December 31, 2022 2021 Principal $ 230,000 $ 230,000 Less: unamortized debt discount (1) — 27,022 Less: unamortized debt issuance costs 3,813 3,273 Net carrying amount $ 226,187 $ 199,705 (1) The Company adopted ASU 2020-06 on January 1, 2022, which resulted in the convertible notes to be accounted for as a single liability Prior to January 1, 2022, the Company separated the Convertible Notes into liability and equity components. On issuance, the carrying amount of the equity component was recorded as a debt discount and subsequently amortized to interest expense. Effective January 1, 2022, the Company adopted ASU 2020-06 using the modified retrospective approach. As a result, the Convertible Notes are accounted for as a single liability measured at amortized cost, as no other embedded features require bifurcation and recognition as derivatives. Adoption of the new standard resulted in a decrease to Accumulated deficit of $23.9 million, a decrease to Additional paid-in capital of $50.0 million, and an increase to Convertible senior notes, net of $26.1 million . The interest expense recognized related to the Convertible Notes was as follows (in thousands): Three Months Ended March 31, 2022 2021 Contractual interest expense $ 144 $ 144 Amortization of debt issuance costs and discount (1) 412 2,794 Total $ 556 $ 2,938 (1) The 2021 amount includes the amortization of the debt discount prior to the adoption of ASU 2020-06 of January 1, 2022 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 March 31, 2022, there were no outstanding borrowings under the 2019 Amended Credit Agreement, there was $150.0 million available for future borrowing, and the Company was in compliance with all the financial covenants. The 2019 Amended Credit Agreement is available for general corporate purposes, including working capital, capital expenditures, and permitted acquisitions. For additional information about the 2019 Amended Credit Agreement, refer to the Company’s consolidated financial statements for the year ended December 31, 2021, included in our Annual Report on Form 10-K for the year ended December 31, 2021.

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 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, net 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. As of March 31, 2022, the fair value of the Convertible Notes was $333.3 million and is presented for required disclosure purposes only. For further information on the Convertible Notes, see Note 7. – Debt.

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. The 2017 Plan has 16,999,318 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 as of January 1, 2022 1,281,411 Granted 227,803 Vested (323,999 ) Forfeited (10,006 ) Outstanding as of March 31, 2022 1,175,209 The weighted average grant date fair value of the RSUs was $62.25 and the RSUs generally vest in four equal annual installments. Total compensation cost related to nonvested awards not yet recognized as of March 31, 2022, totaled $75.7 million, and is expected to be recognized over a weighted average period of 2.6 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 as of January 1, 2022 4,875,562 $ 51.02 8.8 Granted 350,862 $ 62.47 Exercised (299 ) $ 29.22 Forfeited (23,355 ) $ 49.37 Outstanding as of March 31, 2022 5,202,770 $ 51.85 8.7 $ 75.9 Exercisable as of March 31, 2022 106,826 $ 47.38 7.7 $ 1.8 The total intrinsic value of the 2017 Plan stock options exercised during the three months ended March 31, 2022, was not material. 2021 Employee Stock Purchase Plan The Company has an Employee Stock Purchase Plan (“ESPP”) which allows eligible employees to purchase shares of common stock through payroll deductions and is intended to qualify under Section 423 of the Internal Revenue Code. As of March 31, 2022, the Company had 3,123,191 shares of its common stock available for future issuances under the ESPP. The purchase price for each share of common stock purchased under the ESPP will be 85% of the lower of (a) the fair market value per share on the first day of the applicable offering period or (b) the fair market value per share on the applicable purchase date. The Company purchased 76,809 shares of common stock under the ESPP during the three months ended March 31, 2022. As of March 31, 2022, $2.4 million has been withheld on behalf of employees for a future purchase under the ESPP due to the timing of payroll deductions and is reported in Other accrued expenses and current liabilities. The Company recognized $0.7 million of stock-based compensation expense related to the ESPP for the three months ended March 31, 2022. Other In connection with the acquisition of World Programming in December 2021, per the Stock Purchase Agreement, $29.5 million of the Company’s Class A Common Stock will be issued to existing employees, subject to continuing employment and certain other contingencies. The shares will be issued on the one-, two- and three-year anniversaries of the certain legal matters being resolved, subject to potential reduction in certain circumstances. The accounting treatment for these shares in the context of the business combination is to recognize the expense as a post-combination expense, not as transaction consideration. The estimated post combination expense to the Company as a result of the World Programming business combination was approximately $29.5 million which is recognized on an accelerated method over the employment period. As of March 31, 2022, the weighted average remaining service period is 2.75 years. Once the vesting conditions of the service period are met, the Company will issue shares for each award. Stock-based compensation expense includes $4.4 million for the three months ended March 31, 2022. In connection with the acquisition of Powersim Inc. in March 2022, per the Stock Purchase Agreement, $4.3 million of the Company’s Class A Common Stock will be issued to existing employees, subject to continuing employment and certain other contingencies. The shares will be issued on the one - and two-year anniversaries of the certain matters being resolved, subject to potential reduction in certain circumstances.

Earnings Per Share [Abstract]
Net Income Per Share	10 . Net income per share The Company adopted ASU 2020-06 on January 1, 2022, using the modified retrospective method, applicable to its convertible senior notes outstanding as of adoption. The Company has not changed any previously disclosed amounts or provided additional disclosures for comparative periods. ASU 2020-06 requires the if-converted method to be applied for all convertible instruments when calculating diluted earnings per share. Under the if-converted method, shares related to convertible senior notes, to the extent dilutive, are assumed to be converted into common stock at the beginning of the period. Basic net income per share attributable to common stockholders is computed using the weighted average number of shares of common stock outstanding for the period, excluding dilutive securities, stock options, RSUs, and ESPP shares. Diluted net 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 dilutive securities, stock options, RSUs and ESPP shares under the treasury stock method. The following table sets forth the computation of the numerators and denominators used in the basic and diluted net income per share amounts (in thousands, except per share data): Three Months Ended March 31, 2022 2021 Numerator: Net income $ 11,528 $ 14,360 Interest expense related to Convertible Notes, net of tax 144 — Numerator for diluted income per share $ 11,672 $ 14,360 Denominator: Denominator for basic income per share— weighted average shares 79,462 74,651 Effect of dilutive securities, stock options, RSUs and ESPP shares 7,799 4,644 Denominator for dilutive income per share 87,261 79,295 Net income per share attributable to common stockholders, basic $ 0.15 $ 0.19 Net income per share attributable to common stockholders, diluted $ 0.13 $ 0.18 There were no anti-dilutive shares excluded from the computation of diluted net income per share for the three months ended March 31, 2022 or 2021.

Commitments And Contingencies Disclosure [Abstract]
Commitments and Contingencies	1 3 . Commitments and contingencies World Programming The Company acquired World Programming Limited and a related company (collectively, “World Programming”) in December 2021. In 2010, SAS Institute, Inc. (“SAS”) filed an action against World Programing in the United States District Court for the Eastern District of North Carolina (the “NC Court”) alleging copyright infringement, breach of contract, fraudulent inducement to contract, and violations of the North Carolina Unfair and Deceptive Trade Practices Act (UDTPA). SAS was unsuccessful on its copyright claims but prevailed on its breach of contract, fraudulent inducement, and UDTPA claims and was awarded damages of $79.1 million in 2016 (the “NC Judgment”). The NC Court subsequently enjoined World Programming from licensing its WPS Analytics software to new customers for use in the United States until the NC Judgment was satisfied. At the time that the Company acquired World Programming, World Programming had partially paid the NC Judgment. In relation to the NC Court order that enjoined World Programming from licensing its WPS Analytics Software to new customers for use in the United States, SAS filed a related matter in California, which resulted in the California court issuing an order that required certain then existing customers of World Programming to direct payment (of their licensing fees for WPS Analytics software) to SAS until the NC Judgment was satisfied. On January 3, 2022, the Company paid the outstanding balance of $65.9 million on the NC Judgment. Despite payment in full, SAS has asserted that the Company has not satisfied the Judgment. The NC Court scheduled a hearing to address this issue for March 3, 2022 (the “March Hearing”). At the March Hearing, the NC Court confirmed that the Company’s January 3, 2022 payment fully satisfied the NC Judgment, and lifted the injunction that had enjoined World Programming from licensing its WPS Analytics software to new customers for use in the United States. On March 7, 2022, SAS agreed that the California court order was no longer necessary and together with World Programming, filed a joint notice of satisfaction of the NC Judgment with the California court, thereby allowing customers of World Programming to resume payment of their licensing fees to World Programming directly. In 2018, SAS filed litigation in the United States District Court for the Eastern District of Texas (the “Texas Court”) asserting that World Programming infringed SAS copyrights and patents. SAS voluntarily dismissed with prejudice its patent claims, and the Texas Court entered judgment in favor of World Programming on the copyright claims. SAS appealed the Texas Court judgment to the United States Court of Appeals for the Federal Circuit (the “Court of Appeals”). Oral arguments were held before the Court of Appeal on January 13, 2022. A decision from the Court of Appeals is pending. 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. Effects of proceedings 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	1 4 . 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. 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.

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, 2021, included in the most recent Annual Report on Form 10-K filed with the SEC.
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.
Significant Accounting Policies	Significant accounting policies There have been no material changes to our significant accounting policies as of and for the three months ended March 31, 2022, as compared to the significant accounting policies described in our Annual Report on Form 10-K for the year ended December 31, 2021.
Recent Accounting Guidance	Recent accounting guidance Accounting standards adopted Debt – In August 2020, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2020-06, This ASU simplifies the accounting for convertible instruments by eliminating certain separation models. Under ASU 2020 - 06 , a convertible debt instrument will generally be reported as a single liability at its amortized cost with no separate accounting for embedded conversion features. The update also requires the if-converted method to be used for convertible instruments and the effect of potential share settlement be included in the diluted earnings per share calculation when an instrument may be settled in cash or shares. The Company adopted ASU 2020-06 effective as of January 1, 2022, using the modified retrospective approach. Adoption of the new standard resulted in a decrease to accumulated deficit of $23.9 million, a decrease to additional paid-in capital of $50.0 million, and an increase to convertible senior notes, net of $26.1 million. Interest expense recognized in the current and future periods will be reduced as a result of accounting for the convertible debt instrument as a single liability measured at its amortized cost. Accounting standards not yet adopted Reference Rate Reform – In March 2020, the FASB issued ASU 2020-04. 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 optional and 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. Government Assistance – In November 2021, the FASB issued ASU 2021-10, . This ASU requires certain disclosures about transactions with a government that are accounted for by applying a grant or contribution accounting model by analogy. The amendment requires disclosure of information about the nature of the transactions and the related accounting policy used to account for the transactions, information regarding the line items within the consolidated financial statements that are affected by the transactions, and significant terms and conditions of the transactions. ASU 2021-10 is effective for annual periods beginning after December 15, 2021, with early application permitted. The Company is currently evaluating the effect the adoption of this new guidance will have on its consolidated financial statement disclosures.
