Organization

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 defined by the accounting guidance, the Company operates as two segments. However, the Company determined that its two operating segments are sufficiently similar and should be aggregated under the criteria provided in the related accounting guidance.
	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
	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, 2013. The condensed consolidated December 31, 2013 balance sheet presented is derived from the audited December 31, 2013 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 months ended March 31, 2014 are not necessarily indicative of the results that may be expected for any future period.
	The noncontrolling interest position of an acquired subsidiary is reported as a separate component of consolidated equity from the equity attributable to ANSYS stockholders as of March 31, 2014. The noncontrolling interest in the Company's net income was not significant to the consolidated results for the period presented and therefore has been included as a component of other expense, net in the condensed consolidated statements of income.
	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:
		31-Mar-14			31-Dec-13
	(in thousands, except percentages)	Amount		% of Total	Amount		% of Total
	Cash accounts	$	472,734	55.1	$	439,348	59.2
	Money market mutual funds	384,950		44.9	303,138		40.8
	Total	$	857,684		$	742,486
	The Company held 100% and 99% of its money market mutual fund balances in various funds of a single issuer as of March 31, 2014 and December 31, 2013, respectively.

	Acquisitions
	SpaceClaim Corporation
	On April 30, 2014, the Company completed the acquisition of SpaceClaim Corporation ("SpaceClaim"), a leading provider of 3D modeling technology. Under the terms of the agreement, ANSYS acquired SpaceClaim for a purchase price of $85.0 million in cash, plus retention vehicles and an adjustment for working capital. The operating results of SpaceClaim will be included in the Company's consolidated financial statements from the date of acquisition and, accordingly, SpaceClaim's operating results are not included in the financial results presented in this Quarterly Report on Form 10-Q.
	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, ANSYS 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 the date of acquisition, January 3, 2014. 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 the liabilities assumed. The allocation included $9.2 million to identifiable intangible assets including core technology, customer lists and trade names, to be amortized over a period of two to eleven years, and $7.3 million to goodwill, which is not tax deductible. 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). The operating results of Reaction Design are not material to the condensed consolidated financial statements.
	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. Although this acquisition accounting requirement had no impact on the Company’s business or cash flow, the Company’s reported revenue under accounting principles generally accepted in the United States, primarily for the first 12 months post-acquisition, is less than the sum of what would otherwise have been reported by Reaction Design and ANSYS absent the acquisition. Acquired deferred revenue with a historical carrying value of $2.3 million was ascribed no fair value on the opening balance sheet. The impact on reported revenue for the quarter ended March 31, 2014 was $0.8 million. The expected impact on reported revenue is $0.5 million and $2.0 million for the quarter ending June 30, 2014 and for the year ending December 31, 2014, respectively.
	EVEN - Evolutionary Engineering AG
	On April 2, 2013, the Company acquired EVEN - Evolutionary Engineering AG ("EVEN"), a leading provider of composite analysis and optimization technology. Under the terms of the agreement, ANSYS acquired 100% of EVEN for a purchase price of $8.1 million, which consisted of $4.5 million in cash and an estimated $3.6 million of contingent consideration based on EVEN's achievement of certain technical milestones during the three years following the acquisition date. The Company made its first contingent payment totaling $1.6 million in March 2014.
	The total consideration transferred was allocated to the assets and liabilities of EVEN based on management's estimates of the fair values of the assets acquired and the liabilities assumed. The allocation included $2.6 million to identifiable intangible assets including customer lists and core technology, to be amortized over a period of five years, and $5.9 million to goodwill, which is not tax deductible. The fair values of the assets acquired and liabilities assumed are based on management's estimates of their fair value as of the acquisition date.

	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 options are anti-dilutive, they are excluded from the calculation of diluted EPS.
	The details of basic and diluted EPS are as follows:

	During the first quarter of 2014, 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, 2014. No events or circumstances changed during the three months ended March 31, 2014 that would indicate that the fair values of the Company's reporting units or indefinite-lived intangible assets are below their carrying amounts.

Fair_Value_Measurement

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)	March 31,			Quoted Prices in		Significant Other		Significant

	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 table above represents potential future payments related to the EVEN and Apache Design, Inc. ("Apache") acquisitions in accordance with the respective merger agreements. The deferred compensation in the table above is attributable to a retention agreement for a key member of Apache management, and was accounted for outside of that business combination. The net present value calculations for the contingent consideration and deferred compensation 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 months ended March 31, 2014 and 2013:
		Fair Value Measurement Using

	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
	The Company is subject to various investigations, claims and legal proceedings that arise in the ordinary course of business, including alleged infringement of intellectual property rights, commercial disputes, labor and employment matters, tax audits 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. The service tax issues raised in the Company’s notice are very similar to the case, M/s Microsoft Corporation (I) (P) Ltd. Vs Commissions of Service Tax, currently being appealed to the Delhi Customs, Excise and Service Tax Appellate Tribunal (CESTAT). If the ruling is in favor of Microsoft, the Company expects a similar outcome for its audit case. If the ruling is unfavorable in the case of Microsoft, the Company could incur tax charges and related liabilities, including those related to the service tax audit case, of approximately $6 million. Of the two judicial members assigned to the Microsoft appeal, one member has ruled in favor of Microsoft and one has ruled in favor of the Commission. A third deciding judge will be appointed for a final decision. The Company can provide no assurances as to the outcome of the Microsoft appeal or to the impact of the Microsoft appeal 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 March 31, 2014. 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.

Sale-Leaseback Arrangement [Abstract]	'
Sale Leaseback Transaction Disclosure [Text Block]	'
	Sale-Leaseback Arrangement
	On September 14, 2012, the Company entered into a lease agreement for 186,000 square feet of rentable space to be located in a to-be-built office facility in Canonsburg, Pennsylvania, which will serve as the Company's new headquarters. The lease was effective as of September 14, 2012, but because the leased premises are under construction, the Company will not be obligated to pay rent until the later of (i) three months following the date that the leased premises are delivered to ANSYS, which delivery, subject to certain limited exceptions, shall occur no later than October 1, 2014, or (ii) January 1, 2015. The term of the lease is 183 months, beginning on the date the Company takes possession of the facility. The lease agreement terms provide that the Company is responsible for paying the cost of certain tenant improvements that exceed an allowance to be paid by the landlord. There is no cap to the Company's obligation in excess of the landlord allowance, and the improvements do not meet the definition of "normal tenant improvements" as defined in the accounting guidance. As a result, the Company is considered the owner of the building during the construction period and the lease is subject to sale-leaseback treatment.
	As of March 31, 2014, the Company has recorded a $23.7 million construction-in-progress asset and a corresponding liability for construction debt funded by the lessor on its condensed consolidated balance sheet. Upon completion and delivery of the building, the Company will determine whether the lease meets the criteria for capital treatment under the accounting guidance, or whether it has continuing involvement in the lease. If it is determined the lease fails to meet the capitalization criteria, and the Company does not have continuing involvement in the lease, the construction-in-progress asset and liability will be removed from the condensed consolidated balance sheet. The sale-leaseback treatment of the lease during the construction period does not have any impact on the Company's results of operations or cash flows.

	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, 2013. The condensed consolidated December 31, 2013 balance sheet presented is derived from the audited December 31, 2013 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 months ended March 31, 2014 are not necessarily indicative of the results that may be expected for any future period.
	The noncontrolling interest position of an acquired subsidiary is reported as a separate component of consolidated equity from the equity attributable to ANSYS stockholders as of March 31, 2014. The noncontrolling interest in the Company's net income was not significant to the consolidated results for the period presented and therefore has been included as a component of other expense, net in the condensed consolidated statements of income.
