ANSYS, INC. AND SUBSIDIARIES

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

September 30, 2015

(Unaudited)


1.	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.


2.	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 nine months ended September 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:



	September 30, 2015			December 31, 2014
(in thousands, except percentages)	Amount		% of Total	Amount		% of Total
Cash accounts	$	423,132	54.5	$	506,731	64.3
Money market mutual funds	353,107		45.5	281,333		35.7
Total	$	776,239		$	788,064

The Company's money market mutual fund balances are held in various funds of a single issuer.


3.	Acquisitions

2015 Acquisitions

During the nine months ended September 30, 2015, the Company completed various acquisitions to accelerate development of new and innovative products to the marketplace while lowering design and engineering costs for customers. The acquisitions were not individually significant. The combined purchase price of the acquisitions was approximately $44.4 million, which included cash and equity.

The operating results of each acquisition have been included in the Company's condensed consolidated financial statements since each respective date of acquisition. The effects of the business combinations were not individually material to the Company's consolidated results of operations.

Table of Contents

The total consideration transferred was allocated to the assets and liabilities of each acquisition based on management's estimates of the fair values of the assets acquired and liabilities assumed. The allocation included $19.1 million to identifiable intangible assets to be amortized over periods between five and ten years, and $28.5 million to goodwill, inclusive of any measurement-period adjustments recorded since the respective acquisition dates. The fair values of the assets acquired and liabilities assumed are based on provisional calculations and the estimates and assumptions for these items are subject to change during the measurement period (up to one year from the acquisition date) as the Company obtains 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.

In valuing deferred revenue on the balance sheet as of each acquisition date, the Company applied the fair value provisions applicable to the accounting for business combinations. Acquired deferred revenues with a combined historical carrying value of $0.9 million were ascribed no fair value on the opening balance sheets. 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 each acquiree absent the acquisitions. The impacts on reported revenue for the three and nine months ended September 30, 2015 were $0.2 million and $0.6 million, respectively. The expected impacts on reported revenue are $0.2 million for the quarter ending December 31, 2015 and $0.1 million for the year ending December 31, 2016.

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.

Table of Contents

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 made as the Company 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.

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 impacts on reported revenue for the three and nine months ended September 30, 2015 were $0.1 million and $0.6 million, respectively.

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 made

Table of Contents

as the Company 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.

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 the nine months ended September 30, 2015 was $0.2 million.


4.	Other Receivables and Current Assets

The Company's other receivables and current assets comprise the following balances:



(in thousands)	September 30, 2015		December 31, 2014
Receivables related to unrecognized revenue	$	115,689	$	152,830
Income taxes receivable, including overpayments and refunds	10,201		18,276
Prepaid expenses and other current assets	22,270		21,202
Total other receivables and current assets	$	148,160	$	192,308

Receivables for unrecognized revenue represent the current portion of billings made for annual lease licenses and software maintenance that have not yet been recognized as revenue.


5.	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:



	Three Months Ended				Nine Months Ended
(in thousands, except per share data)	September 30, 2015		September 30, 2014		September 30, 2015		September 30, 2014

6.	Goodwill and Intangible Assets

The Company's intangible assets and estimated useful lives are classified as follows:



	September 30, 2015					December 31, 2014
(in thousands)	Gross Carrying Amount		Accumulated Amortization			Gross Carrying Amount		Accumulated Amortization
Amortized intangible assets:
Developed software and core technologies (3 – 11 years)	$	339,745	$	(245,039	)	$	321,076	$	(227,298	)
Customer lists and contract backlog (5 – 15 years)	217,111		(133,903		)	221,159		(121,380		)

Total	$	685,155	$	(452,250	)	$	656,967	$	(411,812	)
Unamortized intangible assets:
Trade names	$	357				$	14,157

The decrease in unamortized trade names in the table above was due to the determination that a trade name no longer had an indefinite life. Amortization expense for the intangible assets reflected above was $14.7 million and $16.3 million for the three months ended September 30, 2015 and 2014, respectively. Amortization expense for the intangible assets reflected above was $44.0 million and $45.6 million for the nine months ended September 30, 2015 and 2014, respectively.

As of September 30, 2015, estimated future amortization expense for the intangible assets reflected above is as follows:



(in thousands)
Remainder of 2015	$	13,946
2016	50,227
2017	47,370
2018	34,015
2019	20,533
2020	19,696
Thereafter	47,118
Total intangible assets subject to amortization	232,905
Indefinite-lived trade name	357
Other intangible assets, net	$	233,262

The changes in goodwill during the nine months ended September 30, 2015 and 2014 were as follows:



(in thousands)	2015			2014
Beginning balance – January 1	$	1,312,182		$	1,255,704
Acquisitions	28,561			60,484
Adjustments⁽¹⁾	(3,601		)	547
Currency translation	(2,633		)	(2,981		)
Ending balance – September 30	$	1,334,509		$	1,313,754

⁽¹⁾ In accordance with the accounting for business combinations, the Company 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 the Company 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 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 nine months ended September 30, 2015 that would indicate that the fair values of the Company's reporting unit and indefinite-lived intangible asset are below their carrying amounts.

7.	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:

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 - Evolutionary Engineering AG ("EVEN") acquisition in accordance with the 2013 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.

11.	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.

Table of Contents

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 September 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.


12.	New Accounting Guidance

Measurement-period adjustments related to business combinations: In September 2015, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update No. 2015-16, Simplifying the Accounting for Measurement-Period Adjustments (ASU 2015-16). ASU 2015-16 requires adjustments to provisional amounts that are identified during the measurement period to be recognized in the period in which the adjustments are determined. The acquirer must record the effect on earnings of changes in depreciation, amortization or other income effects, if any, as a result of the change to the provisional amounts, calculated as if the accounting had been completed at the acquisition date. Prior guidance required the restatement of prior periods if the adjustments impacted those periods. The guidance was early adopted by the Company during the quarter ended September 30, 2015 and applied prospectively. The impact on the Company's financial position, results of operations and cash flows was not material.

Revenue from contracts with customers: In May 2014, the 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. ASU 2015-14, Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date, delayed the effective date of ASU 2014-09 to annual periods beginning after December 15, 2017, including interim periods within that reporting period. Entities have the option of using a full retrospective, cumulative effect or modified approach to adopt ASU 2014-09. 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.

These interim financial statements are the responsibility of the Company’s management.

We conducted our reviews in accordance with the standards of the Public Company Accounting Oversight Board (United States). A review of interim financial information consists principally of applying analytical procedures and making inquiries of persons responsible for financial and accounting matters. It is substantially less in scope than an audit conducted in accordance with the standards of the Public Company Accounting Oversight Board (United States), the objective of which is the expression of an opinion regarding the financial statements taken as a whole. Accordingly, we do not express such an opinion.

Based on our reviews, we are not aware of any material modifications that should be made to such condensed consolidated interim financial statements for them to be in conformity with accounting principles generally accepted in the United States of America.

We have previously audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheet of ANSYS, Inc. and subsidiaries as of December 31, 2014, and the related consolidated statements of income, comprehensive income, stockholders’ equity, and cash flows for the year then ended (not presented herein); and in our report dated February 26, 2015, we expressed an unqualified opinion on those consolidated financial statements. In our opinion, the information set forth in the accompanying condensed consolidated balance sheet as of December 31, 2014 is fairly stated, in all material respects, in relation to the consolidated balance sheet from which it has been derived.

Item 2.Management’s Discussion and Analysis of Financial Condition and Results of Operations

Overview:

The Company's GAAP and non-GAAP results for the quarter ended September 30, 2015 as compared to the quarter ended September 30, 2014 were significantly impacted by a stronger U.S. Dollar. The Company's GAAP results for the three months ended September 30, 2015 reflect increased revenue of 1.6%, decreased operating income of 0.7% and increased diluted earnings per share of 2.9% as compared to the three months ended September 30, 2014. The Company's GAAP results for the nine months ended September 30, 2015 reflect growth in revenue of 1.4%, operating income of 1.3% and diluted earnings per share of 2.6% as compared to the nine months ended September 30, 2014. The Company experienced higher revenue in 2015 primarily from growth in maintenance revenue, partially offset by decreased lease license revenue. The Company also experienced increased operating expenses primarily due to increased employee compensation and other headcount-related costs, partially offset by cost reductions from foreign exchange translation as a result of the stronger U.S. Dollar.

The Company's non-GAAP results for the three months ended September 30, 2015 reflect increased revenue of 1.1%, decreased operating income of 3.5% and increased diluted earnings per share of 1.1% as compared to the three months ended September 30, 2014. The Company's non-GAAP results for the nine months ended September 30, 2015 reflect increased revenue of 1.0%, decreased operating income of 1.0% and increased diluted earnings per share of 0.4% as compared to the nine months ended September 30, 2014. The non-GAAP results exclude the income statement effects of acquisition accounting adjustments to deferred revenue, stock-based compensation, acquisition-related amortization of intangible assets and transaction costs related to business combinations. For further disclosure regarding non-GAAP results, see the section titled "Non-GAAP Results" immediately preceding the section titled "Liquidity and Capital Resources".

The impacts on the Company's revenue and operating income due to the stronger U.S. Dollar for the three and nine months ended September 30, 2015 as compared to the three and nine months ended September 30, 2014 were as follows:



	Three Months Ended September 30, 2015						Nine Months Ended September 30, 2015
(in thousands)	GAAP			Non-GAAP			GAAP			Non-GAAP
Revenue	$	(17,839	)	$	(17,841	)	$	(52,599	)	$	(52,603	)
Operating income	$	(11,113	)	$	(11,486	)	$	(29,949	)	$	(31,134	)

In constant currency⁽¹⁾, the Company's growth rates were as follows:



	Three Months Ended September 30, 2015				Nine Months Ended September 30, 2015
	GAAP		Non-GAAP		GAAP		Non-GAAP
Revenue	9	%	9	%	9	%	9	%
Operating income	12	%	6	%	13	%	8	%

⁽¹⁾Constant currency amounts exclude the effect of foreign currency fluctuations on the reported results. To present this information, the results for 2015 for entities whose functional currency is a currency other than the U.S. Dollar were converted to U.S. Dollars at rates that were in effect for 2014, rather than the actual exchange rates in effect for 2015.

The Company’s financial position includes $776.9 million in cash and short-term investments, and working capital of $633.3 million as of September 30, 2015.

Under the Company’s stock repurchase program, the Company repurchased 1,250,000 shares during the three months ended September 30, 2015 at an average price per share of $91.23, for a total cost of $114.0 million. The Company repurchased 2,792,911 shares during the nine months ended September 30, 2015 at an average price per share of $86.92, for a total cost of $242.7 million.

ANSYS 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 aerospace, automotive, materials and chemical processing, turbomachinery, consumer products, electronics, biomedical, energy, defense and others. Headquartered south of Pittsburgh, Pennsylvania, the Company employed approximately 2,800 people as of September 30, 2015. ANSYS focuses on the development of open and flexible solutions that enable users to analyze designs directly on the desktop,

Table of Contents

providing a common platform for fast, efficient and cost-conscious product development, from design concept to final-stage testing and validation. The Company distributes its suite of simulation technologies through a global network of independent channel partners and direct sales offices in strategic, global locations. It is the Company’s intention to continue to maintain this hybrid sales and distribution model.

The Company licenses its technology to businesses, educational institutions and governmental agencies. Growth in the Company’s revenue is affected by the strength of global economies, general business conditions, currency exchange rate fluctuations, customer budgetary constraints and the competitive position of the Company’s products. The Company believes that the features, functionality and integrated multiphysics capabilities of its software products are as strong as they have ever been. However, the software business is generally characterized by long sales cycles. These long sales cycles increase the difficulty of predicting sales for any particular quarter. The Company makes many operational and strategic decisions based upon short- and long-term sales forecasts that are impacted not only by these long sales cycles but also by current global economic conditions. As a result, the Company believes that its overall performance is best measured by fiscal-year results rather than by quarterly results.

The Company’s management considers the competition and price pressure that it faces in the short- and long-term by focusing on expanding the breadth, depth, ease of use and quality of the technologies, features, functionality and integrated multiphysics capabilities of its software products as compared to its competitors; investing in research and development to develop new and innovative products and increase the capabilities of its existing products; supplying new products and services; focusing on customer needs, training, consulting and support; and enhancing its distribution channels. From time to time, the Company also considers acquisitions to supplement its global engineering talent, product offerings and distribution channels.

Geographic Trends:

The following table presents the Company's geographic constant currency revenue growth during the three and nine months ended September 30, 2015 as compared to the three and nine months ended September 30, 2014:



	Three Months Ended September 30, 2015		Nine Months Ended September 30, 2015
North America	14	%	12	%
Europe	8	%	7	%
General International Area	5	%	8	%
Total	9	%	9	%

In North America, strong performance was observed in the electronics, high-tech, aerospace and defense, and automotive industries as companies continued to rely on ANSYS technology to meet the needs of energy and fuel efficiency, safety and comfort, and the cost-effective delivery of more innovative products in the face of evolving competition and customer requirements. The low price of oil negatively impacted the energy industry as energy companies held back investments, reduced their workforce and considered consolidation and realignment. Healthcare industry market leaders continued to invest in ANSYS solutions throughout the quarter, but performance was negatively impacted by a macroeconomic downturn in the healthcare technology industry.

Europe continued to show progress and overall revenue growth, but with mixed results and pockets of lingering economic and geopolitical issues. The Company experienced strong performance in Germany, Italy, Switzerland, Spain and the Netherlands. However, the Company's performance in Europe continued to be adversely impacted in the third quarter as a result of weakness in markets such as the United Kingdom, France, Sweden and Russia. The ANSYS industry performance trends for the quarter were similar to those in North America. Additionally, weakness in channel partner new business production and a cautious spending environment continued to have an adverse impact. Sales hiring and sales pipeline building activities continued to be a major focus.

The results in the General International Area, which primarily consists of the Asia-Pacific region, continued to demonstrate strength in Japan and India. The growth was adversely impacted by declines in the Company's business in South Korea, Taiwan and Brazil. Additionally, business momentum in the Chinese state-owned enterprises has been slower. In the automotive industry, the economic issues in China negatively impacted the off-road segment. In the industrial equipment industry, continued focus on power generation had a positive impact. The Company continues to focus on improving direct sales execution and the new business production of the channel partner network.

The following discussion should be read in conjunction with the accompanying unaudited condensed consolidated financial statements and notes thereto for the nine months ended September 30, 2015, and with the Company’s audited consolidated financial statements and notes thereto for the year ended December 31, 2014 filed on the Annual Report on Form 10-K with the Securities and Exchange Commission. The Company’s discussion and analysis of its financial condition and results of operations are based upon the Company’s condensed consolidated financial statements, which have been prepared in

Table of Contents

accordance with GAAP. The preparation of these financial statements requires the Company to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities. On an ongoing basis, the Company evaluates its estimates, including those related to the fair value of stock awards, bad debts, contract revenue, valuation of goodwill and other intangible assets, contingent consideration, deferred compensation, income taxes, uncertain tax positions, tax valuation reserves, useful lives for depreciation and amortization, and contingencies and litigation. The Company bases its estimates on historical experience, market experience, estimated future cash flows and various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value of assets and liabilities that are not readily available from other sources. Actual results may differ from these estimates.

This Quarterly Report on Form 10-Q contains forward-looking statements within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934, including, but not limited to, the following statements, as well as statements that contain such words as "anticipates", "intends", "believes", "plans" and other similar expressions:

•

The Company's intentions related to investments in research and development, particularly as it relates to expanding the ease of use and capabilities of its broad portfolio of simulation software products, including the evolution of its ANSYS^® Workbench^™ platform, expansion of high-performance computing capabilities, ANSYS^®AIM^™ immersive user interface, robust design and ongoing integration of acquired technology.


•	The Company's intention to repatriate previously taxed earnings and to reinvest all other earnings of its non-U.S. subsidiaries.


•	The Company's plans related to future capital spending.


•	The sufficiency of existing cash and cash equivalent balances to meet future working capital and capital expenditure requirements.


•	The Company's belief that the best uses of its excess cash are to invest in the business and to repurchase stock in order to both offset dilution and return capital to stockholders in excess of its requirements with the goal of increasing stockholder value.


•	The Company's intentions related to investments in complementary companies, products, services and technologies.


•	The Company's statement regarding increased exposure to volatility of foreign exchange rates.

Forward-looking statements should not be unduly relied upon because they involve known and unknown risks, uncertainties and other factors, some of which are beyond the Company’s control. The Company’s actual results could differ materially from those set forth in forward-looking statements.

Results of Operations

Three Months Ended September 30, 2015 Compared to Three Months Ended September 30, 2014

Revenue:

Total revenue	$	237,840	$	234,000	$	3,840		1.6

The Company’s revenue in the quarter ended September 30, 2015 increased 1.6% as compared to the quarter ended September 30, 2014. The growth rate was adversely impacted by 7.6% due to a strengthening U.S. Dollar and was favorably impacted by the Company’s continued investment in its global sales, support and marketing organizations. Perpetual license revenue, which is derived primarily from new sales during the quarter, increased 3.8% as compared to the prior-year quarter due primarily to growth in perpetual license revenue of electronics products. Annual maintenance contracts that were sold with new perpetual licenses, along with maintenance contracts sold with new perpetual licenses in previous quarters, contributed to maintenance revenue growth of 3.9%.

With respect to revenue, on average for the quarter ended September 30, 2015, the U.S. Dollar was approximately 13.5% stronger, when measured against the Company’s primary foreign currencies, than for the quarter ended September 30, 2014. The net overall strengthening resulted in decreased revenue of $17.8 million during the quarter ended September 30, 2015 as compared with the same quarter of 2014. The impact on revenue was primarily driven by $10.6 million, $4.3 million and $1.2 million of adverse impact due to a weakening Euro, Japanese Yen and South Korean Won, respectively. The net overall strengthening also resulted in decreased operating income of $11.1 million during the quarter ended September 30, 2015 as compared with the same quarter of 2014.

A substantial portion of the Company’s license and maintenance revenue is derived from annual lease and maintenance contracts. These contracts are generally renewed on an annual basis and typically have a high rate of customer renewal. In addition to the recurring revenue base associated with these contracts, a majority of customers purchasing new perpetual licenses also purchase related annual maintenance contracts. As a result of the significant recurring revenue base, the Company’s license and maintenance revenue growth rate in any period does not necessarily correlate to the growth rate of new license and maintenance contracts sold during that period. To the extent the rate of customer renewal for lease and maintenance contracts is high, incremental lease contracts, and maintenance contracts sold with new perpetual licenses, will result in license and maintenance revenue growth in constant currency. Conversely, if the rate of renewal for these contracts is adversely affected by economic or other factors, the Company’s license and maintenance growth will be adversely affected over the term that the revenue for those contracts would have otherwise been recognized.

The Company is starting to experience an increased interest by its customers in enterprise license agreements that often include longer-term, time-based licenses involving a larger number of the Company's software products. While these arrangements typically involve a higher overall transaction price, the revenue from these contracts is typically deferred and recognized over the period of the contract, resulting in increased deferred revenue and backlog. However, to the extent these types of contracts replace sales of perpetual licenses, there could be a near-term adverse impact on software license and maintenance revenue growth.

International and domestic revenues, as a percentage of total revenue, were 60.7% and 39.3%, respectively, during the quarter ended September 30, 2015, and 65.0% and 35.0%, respectively, during the quarter ended September 30, 2014. The Company derived 24.4% and 24.8% of its total revenue through the indirect sales channel for the quarters ended September 30, 2015 and 2014, respectively.

In valuing deferred revenue on the balance sheets of the Company's recent acquisitions as of their respective acquisition dates, the Company applied the fair value provisions applicable to the accounting for business combinations, resulting in a reduction of deferred revenue as compared to its historical carrying amount. 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 each acquiree absent the acquisitions. The

impacts on reported revenue were $0.4 million and $1.5 million for the quarters ended September 30, 2015 and 2014, respectively. The expected impact on reported revenue is $0.3 million and $0.2 million for the quarter ending December 31, 2015 and for the year ending December 31, 2016, respectively.

Deferred Revenue and Backlog:

Deferred revenue consists of billings made or payments received in advance of revenue recognition from lease license and maintenance agreements. The deferred revenue on the Company's condensed consolidated balance sheets does not represent the total value of annual or multi-year, noncancellable lease license and maintenance agreements. The Company's backlog represents installment billings for periods beyond the current quarterly billing cycle and customer orders received but not processed. The Company's deferred revenue and backlog as of September 30, 2015 and December 31, 2014 consist of the following:



	Balance at September 30, 2015
(in thousands)	Total		Current		Long-Term
Deferred revenue	$	334,185	$	319,705	$	14,480
Backlog	102,016		43,701		58,315
Total	$	436,201	$	363,406	$	72,795



	Balance at December 31, 2014
(in thousands)	Total		Current		Long-Term
Deferred revenue	$	345,305	$	332,664	$	12,641
Backlog	122,985		41,390		81,595
Total	$	468,290	$	374,054	$	94,236

Revenue associated with deferred revenue and backlog that is expected to be recognized in the subsequent twelve months is classified as current in the table above.

•	Increased salaries and other headcount-related costs, including incentive compensation, of $5.3 million.


•	Increased consulting and marketing costs, each of $0.5 million.


•	Cost reduction related to foreign exchange translation of $3.2 million.

The Company anticipates that it will continue to make targeted investments in its global sales and marketing organization and its global business infrastructure to enhance and support its revenue-generating activities.

Income Tax Provision: The Company recorded income tax expense of $24.3 million and had income before income taxes of $90.4 million for the quarter ended September 30, 2015. During the quarter ended September 30, 2014, the Company recorded income tax expense of $25.4 million and had income before income taxes of $90.9 million. The effective tax rates were 26.9% and 28.0% for the third quarters of 2015 and 2014, respectively.

The decrease in the effective tax rate is primarily due to tax benefits related to restructuring in a foreign jurisdiction. When compared to the federal and state combined statutory rate, the effective tax rates for the quarters ended September 30, 2015 and 2014 were favorably impacted by the domestic manufacturing deduction and tax benefits associated with the merger of the Company’s Japan subsidiaries in 2010. The quarterly benefit of approximately $3.1 million related to the merger of the Company's Japan subsidiaries was exhausted in the third quarter of 2015 and will not recur in future periods. The rates were also favorably impacted by the lower statutory tax rates in many of the Company's foreign jurisdictions.

Net Income: The Company’s net income in the third quarter of 2015 was $66.0 million as compared to net income of $65.5 million in the third quarter of 2014. Diluted earnings per share was $0.72 in the third quarter of 2015 and $0.70 in the third quarter of 2014. The weighted average shares used in computing diluted earnings per share were 91.6 million and 93.9 million in the third quarters of 2015 and 2014, respectively.

The Company’s revenue in the nine months ended September 30, 2015 increased 1.4% as compared to the nine months ended September 30, 2014. The growth rate was adversely impacted by 7.7% due to a strengthening U.S. Dollar and was favorably impacted by the Company’s continued investment in its global sales, support and marketing organizations. Annual maintenance contracts that were sold with new perpetual licenses, along with maintenance contracts sold with new perpetual licenses in previous quarters, contributed to maintenance revenue growth of 4.5%. This growth was primarily due to maintenance contracts sold with electronics products.

With respect to revenue, on average for the nine months ended September 30, 2015, the U.S. Dollar was approximately 13.4% stronger, when measured against the Company’s primary foreign currencies, than for the nine months ended September 30, 2014. The net overall strengthening resulted in decreased revenue of $52.6 million during the nine months ended September 30, 2015 as compared with the nine months ended September 30, 2014. The impact on revenue was primarily driven by $33.2 million, $12.8 million, $2.4 million and $2.2 million of adverse impact due to a weakening Euro, Japanese Yen, British Pound and South Korean Won, respectively. The net overall strengthening also resulted in decreased operating income of $29.9 million during the nine months ended September 30, 2015 as compared with the nine months ended September 30, 2014.

International and domestic revenues, as a percentage of total revenue, were 62.1% and 37.9%, respectively, during the nine months ended September 30, 2015, and 65.7% and 34.3%, respectively, during the nine months ended September 30, 2014. The Company derived 24.3% of its total revenue through the indirect sales channel for both the nine months ended September 30, 2015 and 2014.

Income Tax Provision: The Company recorded income tax expense of $74.5 million and had income before income taxes of $259.0 million for the nine months ended September 30, 2015. During the nine months ended September 30, 2014, the Company recorded income tax expense of $69.2 million and had income before income taxes of $254.3 million. The effective tax rates were 28.8% and 27.2% for the nine months ended September 30, 2015 and 2014, respectively.

The increase in the effective tax rate is primarily due to tax benefits that occurred in 2014 related to restructuring in a foreign jurisdiction and the reversal of uncertain tax benefits. These benefits did not recur in 2015. When compared to the federal and state combined statutory rate, the effective tax rates for the nine months ended September 30, 2015 and 2014 were favorably impacted by the domestic manufacturing deduction and tax benefits associated with the merger of the Company’s Japan subsidiaries in 2010.

Non-GAAP Measures

Management uses non-GAAP financial measures (a) to evaluate the Company's historical and prospective financial performance as well as its performance relative to its competitors, (b) to set internal sales targets and spending budgets, (c) to allocate resources, (d) to measure operational profitability and the accuracy of forecasting, (e) to assess financial discipline over operational expenditures and (f) as an important factor in determining variable compensation for management and its employees. In addition, many financial analysts that follow the Company focus on and publish both historical results and future projections based on non-GAAP financial measures. The Company believes that it is in the best interest of its investors to provide this information to analysts so that they accurately report the non-GAAP financial information. Moreover, investors have historically requested and the Company has historically reported these non-GAAP financial measures as a means of providing consistent and comparable information with past reports of financial results.

While management believes that these non-GAAP financial measures provide useful supplemental information to investors, there are limitations associated with the use of these non-GAAP financial measures. These non-GAAP financial measures are not prepared in accordance with GAAP, are not reported by all of the Company’s competitors and may not be directly comparable to similarly titled measures of the Company’s competitors due to potential differences in the exact method of calculation. The Company compensates for these limitations by using these non-GAAP financial measures as supplements to GAAP financial measures and by reviewing the reconciliations of the non-GAAP financial measures to their most comparable GAAP financial measures.

Table of Contents

The adjustments to these non-GAAP financial measures, and the basis for such adjustments, are outlined below:

Acquisition accounting for deferred revenue and its related tax impact. Historically, the Company has consummated acquisitions in order to support its strategic and other business objectives. In accordance with the fair value provisions applicable to the accounting for business combinations, acquired deferred revenue is often recorded on the opening balance sheet at an amount that is lower than the historical carrying value. Although this purchase accounting requirement has no impact on the Company’s business or cash flow, it adversely impacts the Company’s reported GAAP revenue in the reporting periods following an acquisition. In order to provide investors with financial information that facilitates comparison of both historical and future results, the Company provides non-GAAP financial measures which exclude the impact of the acquisition accounting adjustment. The Company believes that this non-GAAP financial adjustment is useful to investors because it allows investors to (a) evaluate the effectiveness of the methodology and information used by management in its financial and operational decision-making, and (b) compare past and future reports of financial results of the Company as the revenue reduction related to acquired deferred revenue will not recur when related annual lease licenses and software maintenance contracts are renewed in future periods.

Amortization of intangibles from acquisitions and its related tax impact. The Company incurs amortization of intangibles, included in its GAAP presentation of amortization expense, related to various acquisitions it has made in recent years. Management excludes these expenses and their related tax impact for the purpose of calculating non-GAAP operating income, non-GAAP operating profit margin, non-GAAP net income and non-GAAP diluted earnings per share when it evaluates the continuing operational performance of the Company because these costs are fixed at the time of an acquisition, are then amortized over a period of several years after the acquisition and generally cannot be changed or influenced by management after the acquisition. Accordingly, management does not consider these expenses for purposes of evaluating the performance of the Company during the applicable time period after the acquisition, and it excludes such expenses when making decisions to allocate resources. The Company believes that these non-GAAP financial measures are useful to investors because they allow investors to (a) evaluate the effectiveness of the methodology and information used by management in its financial and operational decision-making, and (b) compare past reports of financial results of the Company as the Company has historically reported these non-GAAP financial measures.

Stock-based compensation expense and its related tax impact. The Company incurs expense related to stock-based compensation included in its GAAP presentation of cost of software licenses; cost of maintenance and service; research and development expense and selling, general and administrative expense. Although stock-based compensation is an expense of the Company and viewed as a form of compensation, management excludes these expenses for the purpose of calculating non-GAAP operating income, non-GAAP operating profit margin, non-GAAP net income and non-GAAP diluted earnings per share when it evaluates the continuing operational performance of the Company. Specifically, the Company excludes stock-based compensation during its annual budgeting process and its quarterly and annual assessments of the Company’s and management’s performance. The annual budgeting process is the primary mechanism whereby the Company allocates resources to various initiatives and operational requirements. Additionally, the annual review by the board of directors during which it compares the Company's historical business model and profitability to the planned business model and profitability for the forthcoming year excludes the impact of stock-based compensation. In evaluating the performance of senior management and department managers, charges related to stock-based compensation are excluded from expenditure and profitability results. In fact, the Company records stock-based compensation expense into a stand-alone cost center for which no single operational manager is responsible or accountable. In this way, management is able to review, on a period-to-period basis, each manager’s performance and assess financial discipline over operational expenditures without the effect of stock-based compensation. The Company believes that these non-GAAP financial measures are useful to investors because they allow investors to (a) evaluate the Company's operating results and the effectiveness of the methodology used by management to review the Company's operating results, and (b) review historical comparability in the Company's financial reporting as well as comparability with competitors' operating results.

Transaction costs related to business combinations. The Company incurs expenses for professional services rendered in connection with business combinations, which are included in its GAAP presentation of selling, general and administrative expense. These expenses are generally not tax-deductible. Management excludes these acquisition-related transaction expenses for the purpose of calculating non-GAAP operating income, non-GAAP operating profit margin, non-GAAP net income and non-GAAP diluted earnings per share when it evaluates the continuing operational performance of the Company, as it generally would not have otherwise incurred these expenses in the periods presented as a part of its continuing operations. The Company believes that these non-GAAP financial measures are useful to investors because they allow investors to (a) evaluate the Company's operating results and the effectiveness of the methodology used by management to review the Company's operating results, and (b) review historical comparability in the Company's financial reporting as well as comparability with competitors' operating results.

Table of Contents

Non-GAAP financial measures are not in accordance with, or an alternative for, GAAP. The Company's non-GAAP financial measures are not meant to be considered in isolation or as a substitute for comparable GAAP financial measures, and should be read only in conjunction with the Company's consolidated financial statements prepared in accordance with GAAP.

The Company has provided a reconciliation of the non-GAAP financial measures to the most directly comparable GAAP financial measures as listed below:



GAAP Reporting Measure	Non-GAAP Reporting Measure
Revenue	Non-GAAP Revenue
Operating Income	Non-GAAP Operating Income
Operating Profit Margin	Non-GAAP Operating Profit Margin

Liquidity and Capital Resources



(in thousands)	September 30, 2015		December 31, 2014		Change
Cash, cash equivalents and short-term investments	$	776,923	$	788,778	$	(11,855	)
Working capital	$	633,307	$	645,394	$	(12,087	)

Cash, Cash Equivalents and Short-Term Investments

Cash and cash equivalents consist primarily of highly liquid investments such as money market mutual funds and deposits held at major banks. Short-term investments consist primarily of deposits held by certain foreign subsidiaries of the Company with original maturities of three months to one year. The following table presents the Company's foreign and domestic holdings of cash, cash equivalents and short-term investments as of September 30, 2015 and December 31, 2014:



(in thousands)	September 30, 2015		% of Total		December 31, 2014		% of Total
Domestic	$	532,995	68.6	%	$	556,328	70.5	%
Foreign	243,928		31.4	%	232,450		29.5	%
Total	$	776,923			$	788,778

If the foreign balances were repatriated to the U.S., they would be subject to domestic tax, resulting in a tax obligation in the period of repatriation. In general, it is the practice and intention of the Company to repatriate previously taxed earnings and to reinvest all other earnings of its non-U.S. subsidiaries. The amount of cash, cash equivalents and short-term investments held by foreign subsidiaries is subject to translation adjustments caused by changes in foreign currency exchange rates as of the end of each respective reporting period, the offset to which is recorded in accumulated other comprehensive loss on the Company’s condensed consolidated balance sheet.

Cash Flows from Operating Activities

(in thousands)	2015		2014		Change
Net cash provided by operating activities	$	258,327	$	293,034	$	(34,707	)

Net cash provided by operating activities decreased during the current fiscal year due to decreased net cash flows from operating assets and liabilities of $40.6 million, primarily due to a $26.8 million refund received in 2014 related to the Company's 2009 and 2010 federal income tax years. These amounts were partially offset by increased net income (net of non-cash operating adjustments) of $5.9 million.

Cash Flows from Investing Activities



	Nine Months Ended September 30,
(in thousands)	2015			2014			Change
Net cash used in investing activities	$	(51,659	)	$	(123,314	)	$	71,655

Net cash used in investing activities decreased during the current fiscal year due primarily to decreased acquisition-related net cash outlays of $61.6 million and decreased capital expenditures of $9.9 million. The Company currently plans capital spending of $15 million to $20 million for the 2015 fiscal year as compared to $26.0 million that was spent in 2014. The planned decrease is attributable to the completion in October 2014 of the Company's new headquarters facility. The level of spending will depend on various factors, including growth of the business and general economic conditions.

Cash Flows from Financing Activities



	Nine Months Ended September 30,
(in thousands)	2015			2014			Change
Net cash used in financing activities	$	(205,438	)	$	(81,969	)	$	(123,469	)

Net cash used in financing activities increased during the current fiscal year due primarily to increased stock repurchases of $134.1 million, partially offset by increased proceeds from shares issued for stock-based compensation of $9.8 million.

Other Cash Flow Information

The Company believes that existing cash and cash equivalent balances of $776.2 million, together with cash generated from operations, will be sufficient to meet the Company’s working capital and capital expenditure requirements through the next twelve months. The Company’s cash requirements in the future may also be financed through additional equity or debt financings. There can be no assurance that such financings can be obtained on favorable terms, if at all.

Under the Company's stock repurchase program, the Company repurchased shares during the nine months ended September 30, 2015 and 2014, as follows:



	Nine Months Ended
(in thousands, except per share data)	September 30, 2015		September 30, 2014
Number of shares repurchased	2,793		1,432
Average price paid per share	$	86.92	$	75.87
Total cost	$	242,748	$	108,613

The Company's repurchase authorization does not have an expiration date and the pace of the repurchase activity will depend on factors such as working capital needs, cash requirements for acquisitions, the Company's stock price, and economic and market conditions. The Company's stock repurchases may be effected from time to time through open market purchases or pursuant to a Rule 10b5-1 plan.

The Company continues to generate positive cash flows from operating activities and believes that the best uses of its excess cash are to invest in the business and to repurchase stock in order to both offset dilution and return capital, in excess of its requirements, to stockholders with the goal of increasing stockholder value. Additionally, the Company has in the past, and expects in the future, to acquire or make investments in complementary companies, products, services and technologies. Any future acquisitions may be funded by available cash and investments, cash generated from operations, credit facilities or the issuance of additional securities.

Off-Balance-Sheet Arrangements

The Company does not have any special-purpose entities or off-balance-sheet financing.

Contractual Obligations

There were no material changes to the Company’s significant contractual obligations during the nine months ended September 30, 2015 as compared to those previously reported in “Management’s Discussion and Analysis of Financial Condition and Results of Operations” within the Company’s most recent Annual Report on Form 10-K.

Critical Accounting Policies and Estimates

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 a previously unamortized trade name that was determined to have a finite life 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 nine months ended September 30, 2015 that would indicate that the fair values of the Company's reporting unit and indefinite-lived intangible asset are below their carrying amounts.

No significant changes have occurred to the Company’s critical accounting policies and estimates as previously reported within “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in the Company’s most recent Annual Report on Form 10-K.

Item 3.Quantitative and Qualitative Disclosures About Market Risk

Interest Income Rate Risk. Changes in the overall level of interest rates affect the interest income that is generated from the Company’s cash, cash equivalents and short-term investments. For the three and nine months ended September 30, 2015, total interest income was $0.7 million and $2.1 million, respectively. Cash and cash equivalents consist primarily of highly liquid investments such as money market mutual funds and deposits held at major banks. Short-term investments consist primarily of deposits held by certain foreign subsidiaries of the Company with original maturities of three months to one year.

Foreign Currency Transaction Risk. As the Company continues to expand its business presence in international regions, the portion of its revenue, expenses, cash, accounts receivable and payment obligations denominated in foreign currencies continues to increase. As a result, changes in currency exchange rates will affect the Company’s financial position, results of operations and cash flows. The Company is most impacted by movements in and among the Euro, Japanese Yen, British Pound, South Korean Won, Canadian Dollar, Indian Rupee and U.S. Dollar.

The Company has foreign-currency-denominated liabilities. In order to provide a natural hedge to mitigate the foreign currency exchange risk on certain of these liabilities, the Company will purchase foreign currencies and hold these currencies in cash until the liabilities are settled.

The most significant currency impacts on revenue and operating income were primarily attributable to U.S. Dollar exchange rate changes against the British Pound, Euro and Japanese Yen as reflected in the charts below:



	Period-End Exchange Rates
As of	GBP/USD	EUR/USD	USD/JPY
September 30, 2014	1.621	1.263	109.649
December 31, 2014	1.557	1.210	119.703
September 30, 2015	1.513	1.118	119.890



	Average Exchange Rates
Three Months Ended	GBP/USD	EUR/USD	USD/JPY
March 31, 2014	1.655	1.370	102.753
June 30, 2014	1.684	1.371	102.137
September 30, 2014	1.669	1.325	103.969
December 31, 2014	1.583	1.249	114.408

June 30, 2015	1.533	1.107	121.336
September 30, 2015	1.549	1.113	122.145

No other material change has occurred in the Company’s market risk subsequent to December 31, 2014.

Item 4.Controls and Procedures

Evaluation of Disclosure Controls and Procedures. As required by Rules 13a-15 and 15d-15 of the Securities Exchange Act of 1934, as amended, or the Exchange Act, the Company has evaluated, with the participation of management, including the Chief Executive Officer and the Chief Financial Officer, the effectiveness of the design and operation of its disclosure controls and procedures as of the end of the period covered by this report. Based on such evaluation, the Chief Executive Officer and Chief Financial Officer have concluded that such disclosure controls and procedures are effective, as defined in Rule 13a-15(e) of the Exchange Act.

The Company has a Disclosure Review Committee to assist in the quarterly evaluation of the Company’s internal disclosure controls and procedures and in the review of the Company’s periodic filings under the Exchange Act. The membership of the Disclosure Review Committee consists of the Company’s Chief Executive Officer, Chief Financial Officer, Global Controller, General Counsel, Senior Director of Investor Relations and Global Insurance, Vice President of Worldwide Sales and Support, Vice President of Human Resources, Vice President of Marketing and Chief Product Officer. This committee is advised by external counsel, particularly on SEC-related matters. Additionally, other members of the Company’s global management team advise the committee with respect to disclosure via a sub-certification process.

The Company believes, based on its knowledge, that the financial statements and other financial information included in this report fairly present, in all material respects, the financial condition, results of operations and cash flows of the Company as of and for the periods presented in this report. The Company is committed to both a sound internal control environment and to good corporate governance.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with policies or procedures may deteriorate.

From time to time, the Company reviews the disclosure controls and procedures and may make changes to enhance their effectiveness and to ensure that the Company’s systems evolve with its business.

Changes in Internal Control. There were no changes in the Company’s internal control over financial reporting that occurred during the three months ended September 30, 2015 that materially affected, or were reasonably likely to materially affect, the Company's internal control over financial reporting.

PART II – OTHER INFORMATION

Item 1.Legal Proceedings

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, in the future, materially affect the Company’s results of operations, cash flows or financial position.

Item 1A.Risk Factors

The Company cautions investors that its performance (and, therefore, any forward-looking statement) is subject to risks and uncertainties. Various important factors may cause the Company’s future results to differ materially from those projected in any forward-looking statement. These factors were disclosed in, but are not limited to, the items within the Company’s most recent Annual Report on Form 10-K, Part I, Item 1A.
