Investments, Debt and Equity Securities [Abstract]

Cash Equivalents and Short-Term Investments

During the nine months ended September 30, 2024, we invested in available-for-sale debt securities, which are included in short-term investments in the condensed consolidated balance sheets. As of September 30, 2024, our cash equivalents and short-term investments were as follows:


(in thousands)	Amortized Cost		Gross Unrealized Gains		Gross Unrealized Losses Less Than 12 Continuous Months		Estimated Fair Value(1)
Cash equivalents:
Money market funds	$	246,657	$	—	$	—	$	246,657
Total cash equivalents	246,657		—		—		246,657
Short-term investments:

Municipal bonds	16,746		117		(8)		16,855

Other short-term investments	183		—		—		183
Total short-term investments	48,846		378		(12)		49,212
Total cash equivalents and short-term investments	$	295,503	$	378	$	(12)	$	295,869

(1) See Note 9, "Fair Value Measurement" for further discussion on fair values.

Of the $27.1 million corporate debt securities, $0.5 million are in a loss position at September 30, 2024. Of the $16.9 million municipal bonds, $4.5 million are in a loss position at September 30, 2024. Of the $5.1 million U.S. agency bonds, $2.0 million are in a loss position at September 30, 2024.

The unrealized losses presented above are primarily attributable to changes in interest rates. We believe that we have the ability to realize the full value of these investments upon maturity.

The following table outlines maturities of our available-for-sale debt securities as of September 30, 2024:


(in thousands)	Amortized Cost		Fair Value
Less than 1 year	$	15,551	$	15,599
1-3 years	33,112		33,430

The revolving loan facility is available for working capital and general corporate purposes. Each of the term loan facility and the revolving loan facility matures on June 30, 2027. Borrowings under the term loan and revolving loan facilities accrue interest at a rate that is based on the Term SOFR plus an applicable margin or at the base rate plus an applicable margin, at our election. The base rate is the highest of (i) the Overnight Bank Funding Rate, plus 0.500%, (ii) the PNC Bank, National Association prime rate, and (iii) Daily Simple SOFR plus an adjustment for SOFR plus 1.00%. The applicable margin for the borrowings is a percentage per annum based on the lower of (1) a pricing level determined by our then-current consolidated net leverage ratio and (2) a pricing level determined by our public debt rating (if available). On September 29, 2023, the 2022 Credit Agreement was amended to provide for an interest rate adjustment (Sustainability Rate Adjustment) based upon the achievement of certain environmental, social and governance key performance indicators (KPIs). The Sustainability Rate Adjustment range is +/- 0.05% and will be adjusted annually based on the KPIs of the preceding year. The 2022 Credit Agreement also provides for the option to add certain foreign subsidiaries as borrowers and to borrow in Euros, Sterling, Yen and Swiss Francs under the revolving loan facility, up to a sublimit of $150.0 million. Borrowings under the revolving loan facility denominated in these currencies will accrue interest at a rate that is based on (a) for Euros, €STR, (b) for Sterling, SONIA, (c) for Yen, TONAR and (d) for Swiss Francs, SARON, plus an applicable margin calculated as described above. Under the 2022 Credit Agreement, the weighted average interest rate in effect for the three and nine months ended September 30, 2024 was 6.25% and 6.27%, respectively, as compared to 6.22% and 5.89% for the three and nine months ended September 30, 2023, respectively. The rate in effect as of September 30, 2024 and for the fourth quarter of 2024 under the 2022 Credit Agreement is 5.53%. The 2022 Credit Agreement contains customary representations and warranties, affirmative and negative covenants and events of default. The 2022 Credit Agreement also contains a financial covenant requiring us and our subsidiaries to maintain a consolidated net leverage ratio not in excess of 3.50 to 1.00 as of the end of any fiscal quarter (for the four-quarter period ending on such date) with an opportunity for a temporary increase in such consolidated net leverage ratio to 4.00 to 1.00 upon the consummation of certain qualified acquisitions for which the aggregate consideration is at least $250.0 million. As of September 30, 2024, we had $755.0 million of borrowings outstanding under the term loan, with a carrying value of $754.1 million, which is net of $0.9 million of unamortized debt discounts and issuance costs. The total amount was included in long-term debt. As of September 30, 2024, no borrowings were outstanding under the revolving loan facility. As of December 31, 2023, we had $755.0 million of borrowings outstanding under the term loan, with a carrying value of $753.9 million, which is net of $1.1 million of unamortized debt discounts and issuance costs. The total amount was included in long-term debt. As of December 31, 2023, no borrowings were outstanding under the revolving loan facility. We were in compliance with all covenants under the 2022 Credit Agreement as of September 30, 2024 and December 31, 2023.

(in thousands)	Gross Carrying Amount		Accumulated Amortization		Gross Carrying Amount		Accumulated Amortization
Finite-lived intangible assets:

Finite-lived intangible assets are amortized over their estimated useful lives of two years to seventeen years.

As of September 30, 2024, estimated future amortization expense for the intangible assets reflected above was as follows:


(in thousands)
Remainder of 2024	$	27,689

The changes in goodwill during the nine months ended September 30, 2024 and 2023 were as follows:

Currency translation	11,845		(2,448)
Ending balance – September 30	$	3,818,560	$	3,769,321

(1) In accordance with the accounting for business combinations, we recorded adjustments to goodwill for the effect of changes in the provisional fair values of the assets acquired and liabilities assumed during the measurement period (up to one year from the acquisition date) as we obtained new information about facts and circumstances that existed as of the acquisition date that, if known, would have affected the measurement of the amounts recognized as of that date.

During the first quarter of 2024, we completed the annual impairment test for goodwill and the indefinite-lived intangible asset and determined that these assets had not been impaired as of the test date, January 1, 2024. No events or circumstances changed during the nine months ended September 30, 2024 that would indicate that the fair values of our reporting unit and indefinite-lived intangible asset are below their carrying amounts.

Accounting Policies	9 Months Ended
Accounting Policies	Sep. 30, 2024
Accounting Policies [Abstract]
Accounting Policies	Accounting Policies Basis of Presentation The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States for interim financial information for commercial and industrial companies, the instructions to Form 10-Q and Rule 10-01 of Regulation S-X. Accordingly, the accompanying unaudited condensed consolidated financial statements do not include all of the information and footnotes required by accounting principles generally accepted in the United States for complete financial statements. The accompanying unaudited condensed consolidated financial statements should be read in conjunction with our audited consolidated financial statements (and notes thereto) included in our Annual Report on Form 10-K for the year ended December 31, 2023 (2023 Form 10-K). The condensed consolidated December 31, 2023 balance sheet presented is derived from the audited December 31, 2023 balance sheet included in the 2023 Form 10-K. In our opinion, 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. Operating results for the three and nine months ended September 30, 2024 are not necessarily indicative of the results that may be expected for any future period. Accounting Guidance Issued and Not Yet Adopted Segment reporting: In November 2023, the FASB issued ASU No. 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures (ASU 2023-07). ASU 2023-07 requires enhanced disclosures related to segment information, including for entities with one reportable segment. It does not change the determination of reportable segments. The enhanced disclosures in accordance with the new guidance are required to be reported in the annual period beginning after December 15, 2023. Early adoption is permitted. The standard only impacts footnote disclosures. Income tax disclosures: In December 2023, the FASB issued ASU No. 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures (ASU 2023-09). ASU 2023-09 requires disclosure of greater disaggregation of information in the rate reconciliation and income taxes paid disaggregated by jurisdiction. It also includes certain other amendments to improve the effectiveness of income tax disclosures. The standard is effective for annual periods beginning after December 15, 2024. Early adoption is permitted. The standard only impacts footnote disclosures. Cash, Cash Equivalents and Short-Term Investments Cash and cash equivalents consist primarily of highly liquid investments such as deposits held at major banks and money market funds. Cash equivalents are carried at cost, which approximates fair value. Our money market fund balances are held in various funds of a single issuer at September 30, 2024. Short-term investments consist of available-for-sale debt securities with remaining maturities greater than three months at the date of purchase and time deposits. Investments in debt securities with remaining maturities greater than three months at the date of purchase are designated as short-term available-for-sale securities, as we may convert these investments into cash at any time, including to fund general operations. We invest in debt securities that have an effective maturity term of less than three years. The debt securities are carried at fair value, with unrealized gains and losses included in the condensed consolidated balance sheets as a component of accumulated other comprehensive (loss) income. For available-for-sale debt securities in an unrealized loss position, we evaluate whether a current expected credit loss exists based on available information relevant to the credit rating of the security, current economic conditions and reasonable and supportable forecasts. The allowance for any credit loss will be recorded in other (expense) income, net, on the condensed consolidated statements of income, not to exceed the amount of the unrealized loss. Any excess unrealized loss other than the credit loss is generally recognized in accumulated other comprehensive loss. The cost of securities sold is based on the specific identification method and realized gains and losses are included in other (expense) income, net. To date, we have not recorded any credit loss or realized gains or losses.

Fair Value Disclosures [Abstract]

Fair Value Measurement

The valuation hierarchy for disclosure of assets and liabilities reported at fair value prioritizes the inputs for such valuations into three broad levels:

•Level 1: quoted prices (unadjusted) in active markets for identical assets or liabilities;

•Level 2: quoted prices for similar assets and liabilities in active markets or inputs that are observable for the asset or liability, either directly or indirectly through market corroboration, for substantially the full term of the financial instrument; or

•Level 3: unobservable inputs based on our own assumptions used to measure assets and liabilities at fair value.

A financial asset's or liability's classification within the hierarchy is determined based on the lowest level input that is significant to the fair value measurement.

Our debt is classified within Level 2 of the fair value hierarchy because these borrowings are not actively traded and have a variable interest rate structure based upon market rates. The carrying amount of our debt approximates the estimated fair value. See Note 11, "Debt", for additional information on our borrowings.

The following tables provide the assets carried at fair value and measured on a recurring basis:

The cash equivalents in the preceding tables represent money market funds, valued at net asset value, with carrying values which approximate their fair values because of their short-term nature.

The short-term investments in the preceding tables represent available-for-sale debt securities and time deposits.

The deferred compensation plan investments in the preceding tables represent trading securities held in a rabbi trust for the benefit of non-employee directors. These securities consist of mutual funds traded in an active market with quoted prices. As a result, the plan assets are classified as Level 1 in the fair value hierarchy. The plan assets are recorded within other long-term assets on our condensed consolidated balance sheets.

The equity securities represent our investment in a publicly traded company. These securities are traded in an active market with quoted prices. As a result, the securities are classified as Level 1 in the fair value hierarchy. The securities are recorded within other long-term assets on our condensed consolidated balance sheets.

The forward contracts represent currency hedges to mitigate exchange rate exposure. These contracts are classified within Level 2 because these contracts are not actively traded and the valuation inputs are based on quoted prices and market observable data of similar instruments. The liabilities associated with the forward contracts are recorded at fair value in other accrued expenses and liabilities in our condensed consolidated balance sheets.

Contingencies and Commitments	Sep. 30, 2024
Commitments and Contingencies Disclosure [Abstract]
Contingencies and Commitments	Contingencies and Commitments We are subject to various claims, investigations, and legal and regulatory proceedings that arise in the ordinary course of business, including, but not limited to, commercial disputes, labor and employment matters, tax audits, alleged infringement of third parties' intellectual property rights and other matters. In our opinion, the resolution of pending matters is not expected to have a material adverse effect on our consolidated results of operations, cash flows or financial position. However, each of these matters is subject to various uncertainties and it is possible that an unfavorable resolution of one or more of these proceedings could materially affect our consolidated results of operations, cash flows or financial position. Our Indian subsidiary has several service tax audits pending that have resulted in formal inquiries being received on transactions through mid-2012. We could incur tax charges and related liabilities of $7.3 million. As such charges are not probable at this time, an estimated liability has not been recorded on the condensed consolidated balance sheet as of September 30, 2024. The service tax issues raised in our notices and inquiries are very similar to the case, M/s Microsoft Corporation (I) (P) Ltd. Vs. Commissioner of Service Tax, New Delhi, wherein the Delhi Customs, Excise and Service Tax Appellate Tribunal (CESTAT) issued a favorable ruling to Microsoft. The Microsoft ruling was subsequently challenged in the Supreme Court of India by the Indian tax authority and a decision is still pending. We can provide no assurances on the impact that the present Microsoft case's decision will have on our cases, however, an unfavorable ruling in the Microsoft case may impact our assessment of probability and result in the recording of a $7.3 million estimated liability. We are uncertain as to when these service tax matters will be concluded. We sell software licenses and services to our customers under contractual agreements. Such agreements generally include certain provisions indemnifying the customer against claims, by third parties, of infringement or misappropriation of their intellectual property rights arising from such customer's usage of our products or services. To date, payments related to these indemnification provisions have been immaterial. For several reasons, including the lack of prior material indemnification claims, we cannot determine the maximum amount of potential future payments, if any, related to such indemnification provisions.

Earnings Per Share [Abstract]

Earnings Per Share

Basic earnings per share (EPS) amounts are computed by dividing earnings by the weighted average number of common shares outstanding during the period. Diluted EPS amounts assume the issuance of common stock for all potentially dilutive equivalents outstanding. To the extent stock awards are anti-dilutive, they are excluded from the calculation of diluted EPS.

The details of basic and diluted EPS are as follows:

Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States for interim financial information for commercial and industrial companies, the instructions to Form 10-Q and Rule 10-01 of Regulation S-X. Accordingly, the accompanying unaudited condensed consolidated financial statements do not include all of the information and footnotes required by accounting principles generally accepted in the United States for complete financial statements. The accompanying unaudited condensed consolidated financial statements should be read in conjunction with our audited consolidated financial statements (and notes thereto) included in our Annual Report on Form 10-K for the year ended December 31, 2023 (2023 Form 10-K). The condensed consolidated December 31, 2023 balance sheet presented is derived from the audited December 31, 2023 balance sheet included in the 2023 Form 10-K. In our opinion, 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. Operating results for the three and nine months ended September 30, 2024 are not necessarily indicative of the results that may be expected for any future period.
Accounting Guidance Issued and Not Yet Adopted	Accounting Guidance Issued and Not Yet Adopted Segment reporting: In November 2023, the FASB issued ASU No. 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures (ASU 2023-07). ASU 2023-07 requires enhanced disclosures related to segment information, including for entities with one reportable segment. It does not change the determination of reportable segments. The enhanced disclosures in accordance with the new guidance are required to be reported in the annual period beginning after December 15, 2023. Early adoption is permitted. The standard only impacts footnote disclosures. Income tax disclosures: In December 2023, the FASB issued ASU No. 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures (ASU 2023-09). ASU 2023-09 requires disclosure of greater disaggregation of information in the rate reconciliation and income taxes paid disaggregated by jurisdiction. It also includes certain other amendments to improve the effectiveness of income tax disclosures. The standard is effective for annual periods beginning after December 15, 2024. Early adoption is permitted. The standard only impacts footnote disclosures.
Cash, Cash Equivalents and Short-Term Investments	Cash, Cash Equivalents and Short-Term Investments Cash and cash equivalents consist primarily of highly liquid investments such as deposits held at major banks and money market funds. Cash equivalents are carried at cost, which approximates fair value. Our money market fund balances are held in various funds of a single issuer at September 30, 2024. Short-term investments consist of available-for-sale debt securities with remaining maturities greater than three months at the date of purchase and time deposits. Investments in debt securities with remaining maturities greater than three months at the date of purchase are designated as short-term available-for-sale securities, as we may convert these investments into cash at any time, including to fund general operations. We invest in debt securities that have an effective maturity term of less than three years. The debt securities are carried at fair value, with unrealized gains and losses included in the condensed consolidated balance sheets as a component of accumulated other comprehensive (loss) income. For available-for-sale debt securities in an unrealized loss position, we evaluate whether a current expected credit loss exists based on available information relevant to the credit rating of the security, current economic conditions and reasonable and supportable forecasts. The allowance for any credit loss will be recorded in other (expense) income, net, on the condensed consolidated statements of income, not to exceed the amount of the unrealized loss. Any excess unrealized loss other than the credit loss is generally recognized in accumulated other comprehensive loss. The cost of securities sold is based on the specific identification method and realized gains and losses are included in other (expense) income, net. To date, we have not recorded any credit loss or realized gains or losses.

Organization	Organization ANSYS, Inc. (Ansys, we, us, our) develops and globally markets engineering simulation software and services widely used by engineers, designers, researchers and students across a broad spectrum of industries and academia, including high-tech, aerospace and defense, automotive, energy, industrial equipment, materials and chemicals, consumer products, healthcare and construction. As defined by the accounting guidance for segment reporting, we operate as one segment. Given the integrated approach to the multi-discipline problem-solving needs of our customers, a single sale may contain components from multiple product areas and include combined technologies. We also have a multi-year product and integration strategy that will result in new, combined products or changes to the historical product offerings. As a result, it is impracticable for us to provide accurate historical or current reporting among our various product lines. Pending Acquisition On January 15, 2024, we entered into an Agreement and Plan of Merger (the Merger Agreement) with Synopsys, Inc., a Delaware corporation (Synopsys), and ALTA Acquisition Corp., a Delaware corporation and wholly owned subsidiary of Synopsys (Merger Sub), under which Synopsys will acquire Ansys. The transaction is anticipated to close in the first half of 2025, subject to the receipt of required regulatory approvals and other customary closing conditions.

Our income before income tax provision, income tax provision and effective tax rates were as follows:


	Three Months Ended						Nine Months Ended
(in thousands, except percentages)	September 30, 2024			September 30, 2023			September 30, 2024			September 30, 2023
Income before income tax provision	$	161,255		$	62,545		$	358,745		$	267,366
Income tax provision	$	33,063		$	7,043		$	65,741		$	41,716
Effective tax rate	20.5		%	11.3		%	18.3		%	15.6		%

The increase in the effective tax rate for the three months ended September 30, 2024 compared to the three months ended September 30, 2023 was a result of an increase in U.S. federal tax expense on foreign earnings and an increase in non-deductible expenses related to business combinations.

Deferred Revenue

Deferred revenue consists of billings made or payments received in advance of revenue recognition from customer 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 time between invoicing and when payment is due is not significant.

The changes in deferred revenue, inclusive of both current and long-term deferred revenue, during the nine months ended September 30, 2024 and 2023 were as follows:


(in thousands)	2024		2023
Beginning balance – January 1	$	479,754	$	435,758
Acquired deferred revenue	—		7,910
Deferral of revenue	1,634,160		1,399,367
Recognition of revenue	(1,662,635)		(1,464,841)
Currency translation	59		(7,761)
Ending balance – September 30	$	451,338	$	370,433

Total revenue allocated to remaining performance obligations as of September 30, 2024 will be recognized as revenue as follows:


(in thousands)
Next 12 months	$	902,792
Months 13-24	343,105
Months 25-36	146,030
Thereafter	71,870
Total revenue allocated to remaining performance obligations	$	1,463,797

Revenue allocated to remaining performance obligations represents contracted revenue that has not yet been recognized, which includes both deferred revenue and backlog. Our backlog represents deferred revenue associated with installment billings for periods beyond the current quarterly billing cycle and committed contracts with start dates beyond the end of the current period. Revenue recognized during the nine months ended September 30, 2024 and 2023 included amounts in deferred revenue and backlog at the beginning of the period of $742.8 million and $706.2 million, respectively.

Business Combinations [Abstract]
Acquisitions	Acquisitions During the three and nine months ended September 30, 2024, we incurred acquisition-related expenses of $13.2 million and $39.9 million, respectively, primarily consisting of costs related to the Merger Agreement with Synopsys. Acquisition-related expenses are recognized as selling, general and administrative and research and development expenses on the condensed consolidated statements of income. On December 5, 2023, we entered into an agreement to make a strategic equity investment in Humanetics in the amount of $300.0 million, subject to receipt of regulatory approvals among other customary closing conditions. As a result of our interactions with regulators, the parties mutually agreed to terminate the investment agreement in July 2024. 2023 Acquisitions On January 3, 2023, we completed the acquisition of DYNAmore for a purchase price of $140.8 million, or $128.0 million net of cash acquired. The acquisition expanded our position as a simulation solution provider within the automotive industry. The effects of the acquisition were not material to our condensed consolidated results of operations. Additionally, during the year ended December 31, 2023, we completed other acquisitions to expand our solution offerings and enhance our customers' experience. These acquisitions were not significant, individually or in the aggregate. The combined purchase price of these acquisitions during the year ended December 31, 2023 was approximately $94.4 million, or $88.3 million net of cash acquired. The operating results of each acquisition have been included in our condensed consolidated financial statements since each respective date of acquisition. The effects of the acquisitions were not material to our condensed consolidated results of operations.
