Organization

Organization	6 Months Ended

Organization	Organization ANSYS, Inc. (hereafter the "Company" or "ANSYS") develops and globally markets engineering simulation software and technologies widely used by engineers, designers, researchers and students across a broad spectrum of industries and academia, including aerospace, automotive, manufacturing, electronics, biomedical, energy and defense. As of January 1, 2015, the Company began to operate as one segment when two legal entities merged and a third insignificant acquired segment was no longer separately reported internally. Given the integrated approach to the multi-discipline problem-solving needs of the Company’s customers, a single sale of software may contain components from multiple product areas and include combined technologies. The Company also has a multi-year product and integration strategy that will result in new, combined products or changes to or discontinuation of the historical product offerings. As a result, it is impracticable for the Company to provide accurate historical or current reporting among its various product lines.

Accounting Policies	Accounting Policies Basis of Presentation The accompanying unaudited condensed consolidated financial statements have been prepared by ANSYS in accordance with accounting principles generally accepted in the United States for interim financial information for commercial and industrial companies and the instructions to the Quarterly Report on Form 10-Q and Rule 10-01 of Regulation S-X. Accordingly, the accompanying 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 condensed consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements (and notes thereto) included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2014 . The condensed consolidated December 31, 2014 balance sheet presented is derived from the audited December 31, 2014 balance sheet included in the most recent Annual Report on Form 10-K. 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. Operating results for the three and six months ended June 30, 2015 are not necessarily indicative of the results that may be expected for any future period. Cash and Cash Equivalents Cash and cash equivalents consist primarily of highly liquid investments such as deposits held at major banks and money market mutual funds. Cash equivalents are carried at cost, which approximates fair value. The Company’s cash and cash equivalent balances comprise the following: June 30, 2015 December 31, 2014 (in thousands, except percentages) Amount % of Total Amount % of Total Cash accounts $ 431,664 51.4 $ 506,731 64.3 Money market mutual funds 408,690 48.6 281,333 35.7 Total $ 840,354 $ 788,064 The Company's money market mutual fund balances are held in various funds of a single issuer.

Acquisitions

Acquisitions	Acquisitions Newmerical Technologies International On February 3, 2015, the Company acquired certain assets and liabilities of Newmerical Technologies International ("NTI"), a leading developer of in-flight icing simulation software, for a purchase price of approximately $10.4 million in cash, plus retention vehicles and an adjustment for working capital. NTI's software can solve problems in aerodynamics, in-flight icing, heat transfer, fluid-structure interaction and wind engineering for customers in the aerospace, architectural, automotive and marine industries. The complementary combination is expected to accelerate development of new and innovative products to the marketplace while lowering design and engineering costs for customers. The operating results of NTI have been included in the Company's condensed consolidated financial statements since February 3, 2015, the date of acquisition. The total consideration transferred was allocated to the assets and liabilities of NTI based on management's estimates of the fair values of the assets acquired and liabilities assumed. The allocation included $3.6 million to identifiable intangible assets, including core technology and customer lists, to be amortized over periods between five and seven years, and $5.3 million to goodwill, which is partially tax-deductible. These amounts include measurement-period adjustments. The fair values of the assets acquired and liabilities assumed are based on preliminary calculations and the estimates and assumptions for these items are subject to change as additional information about what was known and knowable at the acquisition date is obtained during the measurement period (up to one year from the acquisition date). Pro forma results of operations have not been presented as the effects of the NTI business combination were not material to the Company's consolidated results of operations. In valuing deferred revenue on the NTI balance sheet as of the acquisition date, the Company applied the fair value provisions applicable to the accounting for business combinations. Acquired deferred revenue with a historical carrying value of $0.5 million was ascribed no fair value on the opening balance sheet. As a result, the Company's post-acquisition revenue will be less than the sum of what would have otherwise been reported by ANSYS and NTI absent the acquisition. The impact on reported revenue for the three and six months ended June 30, 2015 was $0.2 million and $0.4 million , respectively. The expected impact on reported revenue is $0.1 million for the quarter ending September 30, 2015 and $0.5 million for the year ending December 31, 2015. SpaceClaim Corporation On April 30, 2014, the Company completed the acquisition of SpaceClaim Corporation ("SpaceClaim"), a leading provider of 3-D modeling technology. Under the terms of the agreement, the Company acquired SpaceClaim for a purchase price of $85.0 million , which was paid almost entirely in cash. SpaceClaim's software provides customers with a powerful and intuitive 3-D direct modeling solution to author new concepts and then leverage the power of simulation to rapidly iterate on these designs to drive innovation. The broad appeal of the SpaceClaim technology can help the Company deliver simulation tools to any engineer in any industry. The operating results of SpaceClaim have been included in the Company's condensed consolidated financial statements since April 30, 2014, the date of acquisition. The assets and liabilities of SpaceClaim have been recorded based upon management's estimates of their fair market values as of the acquisition date. The following tables summarize the fair value of consideration transferred and the fair values of identified assets acquired and liabilities assumed at the acquisition date, as adjusted within the one-year measurement period: Fair Value of Consideration Transferred: (in thousands) Cash $ 84,892 ANSYS replacement stock options 68 Total consideration transferred at fair value $ 84,960 Recognized Amounts of Identifiable Assets Acquired and Liabilities Assumed: (in thousands) Cash $ 723 Accounts receivable and other tangible assets 1,857 Developed technology (10-year life) 15,800 Customer relationships (6-year life) 9,400 Trade name (6-year life) 1,300 Contract backlog (6-year life) 550 Non-compete agreement (2-year life) 300 Net deferred tax assets 9,288 Accounts payable and other liabilities (2,011 ) Deferred revenue (700 ) Total identifiable net assets $ 36,507 Goodwill $ 48,453 The goodwill, which is not tax-deductible, is attributed to intangible assets that do not qualify for separate recognition, including the assembled workforce of the acquired business and the synergies expected to arise as a result of the acquisition of SpaceClaim. During the one-year measurement period since the SpaceClaim acquisition date, the Company adjusted the fair values of the assets acquired and liabilities assumed, with the offset recorded as a $4.8 million decrease to goodwill. These adjustments were based on refinements to assumptions used in the preliminary valuation of deferred revenue, accounts payable and other liabilities, and information about what was known and knowable as of the acquisition date in the calculation of the net deferred tax assets. In valuing deferred revenue on the SpaceClaim balance sheet as of the acquisition date, the Company applied the fair value provisions applicable to the accounting for business combinations. Acquired deferred revenue with a historical carrying value of $3.3 million was ascribed a fair value of $0.7 million on the opening balance sheet. As a result, the Company's post-acquisition revenue will be less than the sum of what would have otherwise been reported by ANSYS and SpaceClaim absent the acquisition. The impact on reported revenue for the three and six months ended June 30, 2015 was $0.2 million and $0.5 million , respectively. The expected impact on reported revenue is $0.1 million for the quarter ending September 30, 2015 and $0.6 million for the year ending December 31, 2015. Reaction Design On January 3, 2014, the Company completed the acquisition of Reaction Design, a leading developer of chemistry simulation software. Under the terms of the agreement, the Company acquired Reaction Design for a purchase price of $19.1 million in cash. Reaction Design's solutions enable transportation manufacturers and energy companies to rapidly achieve their clean technology goals by automating the analysis of chemical processes via computer simulation and modeling solutions. The operating results of Reaction Design have been included in the Company's condensed consolidated financial statements since January 3, 2014, the date of acquisition. The total consideration transferred was allocated to the assets and liabilities of Reaction Design based on management's estimates of the fair values of the assets acquired and liabilities assumed. The allocation included $7.0 million to identifiable intangible assets, including core technology, customer lists and trade names, to be amortized over periods between two and eleven years, and $9.2 million to goodwill, which is not tax-deductible. These amounts include measurement-period adjustments. During the one-year measurement period since the Reaction Design acquisition date, the Company adjusted the fair values of the assets acquired and liabilities assumed, with the offset recorded as an increase to goodwill of $1.9 million and a reduction in noncontrolling interest of $0.6 million . These adjustments were based on refinements to assumptions used in the preliminary valuation of intangible assets and information about what was known and knowable as of the acquisition date in the calculation of the net deferred tax assets. In valuing deferred revenue on the Reaction Design balance sheet as of the acquisition date, the Company applied the fair value provisions applicable to the accounting for business combinations. Acquired deferred revenue with a historical carrying value of $2.3 million was ascribed no fair value on the opening balance sheet. As a result, the Company's post-acquisition revenue will be less than the sum of what would have otherwise been reported by ANSYS and Reaction Design absent the acquisition. The impact on reported revenue for each of the three and six months ended June 30, 2015 was $0.1 million . The expected impact on reported revenue is $0.2 million for the year ending December 31, 2015.

Earnings Per Share	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: Three Months Ended Six Months Ended (in thousands, except per share data) June 30, June 30, June 30, June 30, Net income $ 62,335 $ 63,036 $ 118,467 $ 119,578 Weighted average shares outstanding – basic 89,866 92,314 89,962 92,398 Dilutive effect of stock plans 1,860 2,024 1,971 2,246 Weighted average shares outstanding – diluted 91,726 94,338 91,933 94,644 Basic earnings per share $ 0.69 $ 0.68 $ 1.32 $ 1.29 Diluted earnings per share $ 0.68 $ 0.67 $ 1.29 $ 1.26 Anti-dilutive shares 223 1,191 230 1,198

Amortization expense for the intangible assets reflected above was $14.8 million and $15.2 million for the three months ended June 30, 2015 and 2014 , respectively. Amortization expense for the intangible assets reflected above was $29.2 million and $29.3 million for the six months ended June 30, 2015 and 2014 , respectively. As of June 30, 2015 , estimated future amortization expense for the intangible assets reflected above is as follows: (in thousands) Remainder of 2015 $ 28,534 2016 49,244 2017 45,736 2018 32,105 2019 18,627 2020 17,825 Thereafter 40,421 Total intangible assets subject to amortization 232,492 Indefinite-lived trade names 357 Other intangible assets, net $ 232,849 The changes in goodwill during the six months ended June 30, 2015 and 2014 were as follows: (in thousands) 2015 2014 Beginning balance – January 1 $ 1,312,182 $ 1,255,704 Acquisitions 5,411 60,484 Adjustments (1) (3,601 ) 948 Currency translation (1,871 ) 53 Ending balance – June 30 $ 1,312,121 $ 1,317,189 (1) In accordance with accounting for business combinations, the Company recorded adjustments to goodwill for the effect of changes in the preliminary fair values of the assets acquired and liabilities assumed during the measurement period (up to one year from the acquisition date) as the Company continued to consider what was known and knowable as of the acquisition date. During the first quarter of 2015 , the Company completed the annual impairment test for goodwill and indefinite-lived intangible assets and determined that these assets had not been impaired as of the test date, January 1, 2015 . The Company tested the previously unamortized trade name discussed above for impairment during the first quarter of 2015 and determined that its fair value exceeded its carrying value, so no impairment was recorded. No other events or circumstances changed during the six months ended June 30, 2015 that would indicate that the fair values of the Company's reporting unit or indefinite-lived intangible asset are below their carrying amounts.

Fair Value Measurement

Fair Value Measurement	6 Months Ended
	Jun. 30, 2015
Fair Value Measurement	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 the Company's 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. The following tables provide the assets and liabilities carried at fair value and measured on a recurring basis: Fair Value Measurements at Reporting Date Using: (in thousands) June 30, Quoted Prices in Active Markets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Assets Cash equivalents $ 408,690 $ 408,690 $ — $ — Short-term investments $ 816 $ — $ 816 $ — Liabilities Contingent consideration $ (1,394 ) $ — $ — $ (1,394 ) Fair Value Measurements at Reporting Date Using: (in thousands) December 31, 2014 Quoted Prices in Active Markets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Assets Cash equivalents $ 281,333 $ 281,333 $ — $ — Short-term investments $ 714 $ — $ 714 $ — Liabilities Contingent consideration $ (2,621 ) $ — $ — $ (2,621 ) The cash equivalents in the preceding tables represent money market mutual funds. The short-term investments in the preceding tables represent deposits held by certain foreign subsidiaries of the Company. The deposits have fixed interest rates with maturity dates ranging from three months to one year. The contingent consideration in the tables above represents potential future payments related to the EVEN acquisition in accordance with the merger agreement. The net present value calculations for the contingent consideration include significant unobservable inputs in the assumption that all remaining payments will be made, and therefore the liabilities were classified as Level 3 in the fair value hierarchy. The following tables present the changes in the Company’s Level 3 liabilities that are measured at fair value on a recurring basis during the three and six months ended June 30, 2015 and 2014 : Fair Value Measurement Using Significant Unobservable Inputs (in thousands) Contingent Consideration Balance as of January 1, 2015 $ 2,621 Interest expense and foreign exchange activity included in earnings 122 Balance as of March 31, 2015 $ 2,743 Contingent payment (1,456 ) Interest expense and foreign exchange activity included in earnings 107 Balance as of June 30, 2015 $ 1,394 Fair Value Measurement Using Significant Unobservable Inputs (in thousands) Contingent Consideration Deferred Compensation Balance as of January 1, 2014 $ 7,389 $ 704 Contingent payment (1,578 ) — Interest expense and foreign exchange activity included in earnings 164 3 Balance as of March 31, 2014 $ 5,975 $ 707 Interest expense and foreign exchange activity included in earnings 87 4 Balance as of June 30, 2014 $ 6,062 $ 711 The carrying values of cash, accounts receivable, accounts payable, accrued expenses, other accrued liabilities and short-term obligations approximate their fair values because of their short-term nature.

Contingencies and Commitments

Contingencies and Commitments	6 Months Ended

Contingencies and Commitments	Contingencies and Commitments The Company is subject to various investigations, claims and legal proceedings that arise in the ordinary course of business, including commercial disputes, labor and employment matters, tax audits, alleged infringement of intellectual property rights and other matters. In the opinion of the Company, the resolution of pending matters is not expected to have a material, adverse effect on the Company’s 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 the Company’s results of operations, cash flows or financial position. An Indian subsidiary of the Company received a formal inquiry after a service tax audit was held in 2011. The Company could incur tax charges and related liabilities, including those related to the service tax audit case, of approximately $6 million . The service tax issues raised in the Company’s notice 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) has passed a favorable ruling to Microsoft. The Company can provide no assurances on whether the Microsoft case’s favorable ruling will be challenged in higher courts or on the impact that the present Microsoft case’s decision will have on the Company’s audit case. The Company is uncertain as to when the service tax audit will be completed. The Company sells software licenses and services to its customers under proprietary software license agreements. Each license agreement contains the relevant terms of the contractual arrangement with the customer, and generally includes certain provisions for indemnifying the customer against losses, expenses and liabilities from damages that are incurred by or awarded against the customer in the event the Company’s software or services are found to infringe upon a patent, copyright or other proprietary right of a third party. To date, the Company has not had to reimburse any of its customers for any losses related to these indemnification provisions and no material claims asserted under these indemnification provisions are outstanding as of June 30, 2015 . For several reasons, including the lack of prior material indemnification claims, the Company cannot determine the maximum amount of potential future payments, if any, related to such indemnification provisions.

New Accounting Guidance

New Accounting Guidance	Revenue from contracts with customers: In May 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update No. 2014-09, Revenue from Contracts with Customers (Topic 606) (ASU 2014-09). ASU 2014-09 supersedes most current revenue recognition guidance, including industry-specific guidance. Previous guidance requires an entity to recognize revenue when persuasive evidence of an arrangement exists, delivery has occurred or services have been rendered, the seller's price to the buyer is fixed or determinable, and collectibility is reasonably assured. Under the new guidance, an entity is required to evaluate revenue recognition by identifying a contract with a customer, identifying the performance obligations in the contract, determining the transaction price, allocating the transaction price to the performance obligations in the contract and recognizing revenue when (or as) the entity satisfies a performance obligation. This guidance will be effective for annual periods beginning after December 15, 2016, including interim periods within that reporting period. In July 2015, the FASB voted in favor of a one-year delay in the required adoption date of this standard to annual periods beginning after December 15, 2017. Entities have the option of using a full retrospective, cumulative effect or modified approach to adopt the guidance. This update will impact the timing and amounts of revenue recognized. The Company is currently evaluating the effect that implementation of this update will have on its financial results upon adoption.
