EXHIBIT 99.1

               Certain Factors Regarding Future Results

               Information provided by the Company or its spokespersons may from
               time to time contain forward-looking statements concerning
               projected financial performance, market and industry segment
               growth, product development and commercialization or other
               aspects of future operations. Such statements will be based on
               the assumptions and expectations of the Company's management at
               the time such statements are made. The Company cautions investors
               that its performance (and, therefore, any forward-looking
               statement) is subject to risks and uncertainties. Various
               important factors including, but not limited to, the following
               may cause the Company's future results to differ materially from
               those projected in any forward-looking statement.

               POTENTIAL FLUCTUATIONS IN OPERATING RESULTS: The Company may
               experience significant fluctuations in future quarterly operating
               results. Fluctuations may be caused by many factors, including
               the timing of new product releases or product enhancements by the
               Company or its competitors; the size and timing of individual
               orders, including a fluctuation in the demand for and the ability
               to complete large contracts; software errors or other product
               quality problems; competition and pricing; customer order
               deferrals in anticipation of new products or product
               enhancements; reduction in demand for the Company's products;
               changes in operating expenses; changes in the mix of software
               license and maintenance and service revenue; personnel changes
               and general economic conditions. A substantial portion of the
               Company's operating expenses is related to personnel, facilities
               and marketing programs. The level of personnel and related
               expenses cannot be adjusted quickly and is based, in significant
               part, on the Company's expectation for future revenue. The
               Company does not typically experience significant order backlog.
               Further, the Company has often recognized a substantial portion
               of its revenue in the last month of a quarter, with this revenue
               frequently concentrated in the last weeks or days of a quarter.
               During certain quarterly periods, the Company has been dependent
               upon receiving large orders of perpetual licenses involving the
               payment of a single up-front fee and, more recently, has shifted
               the business emphasis of its products to provide a collaborative
               solution to the Company's customers. This emphasis has increased
               the Company's average order size and increased the related sales
               cycle time for the larger orders and may have the effect of
               increasing the volatility of the Company's revenue and profit
               from period to period. As a result, product revenue in any
               quarter is

                                                                              27



               substantially dependent on sales completed in the latter part of
               that quarter, and revenue for any future quarter is not
               predictable with any significant degree of accuracy.

               STOCK MARKET AND STOCK PRICE VOLATILITY: Market prices for
               securities of software companies have generally been volatile. In
               particular, the market price of the Company's common stock has
               been and may continue to be subject to significant fluctuations
               as a result of factors affecting the Company, the software
               industry or the securities markets in general. Such factors
               include, but are not limited to, declines in trading price that
               may be triggered by the Company's failure to meet the
               expectations of securities analysts and investors. The Company
               cannot provide assurance that in such circumstances the trading
               price of the Company's common stock will recover or that it will
               not experience a further decline. Moreover, the trading price
               could be subject to additional fluctuations in response to
               quarter-to-quarter variations in the Company's operating results,
               material announcements made by the Company or its competitors,
               conditions in the software industry generally or other events and
               factors, many of which are beyond the Company's control.

               RAPIDLY CHANGING TECHNOLOGY; NEW PRODUCTS; RISK OF PRODUCT
               DEFECTS: The markets for the Company's products are generally
               characterized by rapidly changing technology and frequent new
               product introductions that can render existing products obsolete
               or unmarketable. A major factor in the Company's future success
               will be its ability to anticipate technological changes and to
               develop and introduce, in a timely manner, enhancements to its
               existing products and new products to meet those changes. If the
               Company is unable to introduce new products and respond quickly
               to industry changes, its business, financial condition and
               results of operations could be materially adversely affected. The
               introduction and marketing of new or enhanced products require
               the Company to manage the transition from existing products in
               order to minimize disruption in customer purchasing patterns.
               There can be no assurance that the Company will be successful in
               developing and marketing, on a timely basis, new products or
               product enhancements, that its new products will adequately
               address the changing needs of the marketplace or that it will
               successfully manage the transition from existing products.
               Software products as complex as those offered by the Company may
               contain undetected errors or failures when first introduced or as
               new versions are released, and the likelihood of errors is
               increased as a result of the Company's commitment to accelerating
               the frequency of its product releases.
                 There can be no assurance that errors will not be found in new
               or enhanced products after commencement

                                                                              28



               of commercial shipments. Any of these problems may result in the
               loss of or delay in market acceptance, diversion of development
               resources, damage to the Company's reputation or increased
               service and warranty costs, any of which could have a materially
               adverse effect on the Company's business, financial condition and
               results of operations.

               DEPENDENCE ON DISTRIBUTORS: The Company continues to distribute
               most of its products through its global network of 30
               independent, regional ASDs. The ASDs sell ANSYS and DesignSpace
               products to new and existing customers, expand installations
               within their existing customer base, offer consulting services
               and provide the first line of technical support. The ASDs have
               more immediate contact with most customers who use ANSYS software
               than does the Company. Consequently, the Company is highly
               dependent on the efforts of the ASDs. Difficulties in ongoing
               relationships with ASDs, such as delays in collecting accounts
               receivable, failure to meet performance criteria or to promote
               the Company's products as aggressively as the Company expects and
               differences in the handling of customer relationships could
               adversely affect the Company's performance. Additionally, the
               loss of any major ASD for any reason, including an ASD's decision
               to sell competing products rather than the Company's products,
               could have a materially adverse effect on the Company. Moreover,
               the Company's future success will depend substantially on the
               ability and willingness of its ASDs to continue to dedicate the
               resources necessary to promote the Company's products and to
               support a larger installed base of the Company's products. If the
               ASDs are unable or unwilling to do so, the Company may be unable
               to sustain revenue growth.

                    COMPETITION: The CAD, CAE and computer-aided manufacturing
               ("CAM") markets are intensely competitive. In the traditional CAE
               market, the Company's primary competitors include MSC.Software
               Corporation and ABAQUS Inc. (formerly Hibbitt, Karlsson and
               Sorenson, Inc.) The Company also faces competition from smaller
               vendors of specialized analysis applications in fields such as
               computational fluid dynamics. In addition, certain integrated CAD
               suppliers such as Parametric Technology Corporation, Electronic
               Data Systems Corporation and Dassault Systemes provide varying
               levels of design analysis, optimization and verification
               capabilities as part of their product offerings. The entrance of
               new competitors would likely intensify competition in all or a
               portion of the overall CAD, CAE and CAM markets. Some of the
               Company's current and possible future competitors have greater
               financial, technical, marketing and other resources than the
               Company, and some have well established relationships with
               current and potential customers of the Company. It is also
               possible that alliances among competitors may emerge and rapidly

                                                                              29



               acquire significant market share or that competition will
               increase as a result of software industry consolidation.
               Increased competition may result in price reductions, reduced
               profitability and loss of market share, any of which would
               materially adversely affect the Company's business, financial
               condition and results of operations.

               DEPENDENCE ON SENIOR MANAGEMENT AND KEY TECHNICAL PERSONNEL: The
               Company is highly dependent upon the ability and experience of
               its senior executives and its key technical and other management
               employees. Although the Company has an employment agreement with
               one executive, the loss of this employee, or any of the Company's
               other key employees, could adversely affect the Company's ability
               to conduct its operations.

               RISKS ASSOCIATED WITH INTERNATIONAL ACTIVITIES: A significant
               portion of the Company's business comes from outside the United
               States of America. Risks inherent in the Company's international
               business activities include imposition of government controls,
               export license requirements, restrictions on the export of
               critical technology, political and economic instability, trade
               restrictions, changes in tariffs and taxes, difficulties in
               staffing and managing international operations, longer accounts
               receivable payment cycles and the burdens of complying with a
               wide variety of foreign laws and regulations. Effective patent,
               copyright and trade secret protection may not be available in
               every foreign country in which the Company sells its products.
               The Company's business, financial condition and results of
               operations could be materially adversely affected by any of these
               risks.
                 Additionally, countries in certain international regions have
               continued to experience weaknesses in their currency, banking and
               equity markets. These weaknesses could adversely affect consumer
               demand for the Company's products and ultimately the Company's
               financial condition or results of operations.
                 In November 2000, the United States enacted the FSC Repeal and
               Extraterritorial Income Exclusion Act (the "Act") in response to
               a challenge from the World Trade Organization ("WTO") that the
               existing tax benefits provided by foreign sales corporations were
               prohibited tax subsidies. The Act generally repeals the foreign
               sales corporation and implements an extraterritorial income
               ("ETI") tax benefit. Recently, the European Union stated that it
               did not believe the ETI provisions bring U.S. tax law into
               WTO-compliance and asked the WTO to rule on the matter. On August
               30, 2002, the WTO ruled that the European Union may impose up to
               $4 billion per year in retaliatory duties against U.S. exports.
               As a result, there may be further related changes to U.S. export
               tax law in connection with this ruling. In 2001, export benefits
               reduced the Company's effective tax rate by 6.6%. Any such
               prospective changes regarding tax benefits

                                                                              30



               associated with the Company's export sales may adversely impact
               the Company's effective tax rate and decrease its net income in
               future periods.

               DEPENDENCE ON PROPRIETARY TECHNOLOGY: The Company's success is
               highly dependent upon its proprietary technology. Although the
               Company was awarded a patent by the U.S. Patent and Trademark
               Office for its web-based reporting technology, the Company
               generally relies on contracts and the laws of copyright and trade
               secrets to protect its technology. Although the Company maintains
               a trade secrets program, enters into confidentiality agreements
               with its employees and distributors and limits access to and
               distribution of its software, documentation and other proprietary
               information, there can be no assurance that the steps taken by
               the Company to protect its proprietary technology will be
               adequate to prevent misappropriation of its technology by third
               parties, or that third parties will not be able to develop
               similar technology independently. Although the Company is not
               aware that any of its technology infringes upon the rights of
               third parties, there can be no assurance that other parties will
               not assert technology infringement claims against the Company, or
               that, if asserted, such claims will not prevail.

               INCREASED RELIANCE ON PERPETUAL LICENSES: The Company has
               historically maintained stable recurring revenue from the sale of
               monthly lease licenses and noncancellable annual leases for its
               software products. More recently, the Company has experienced an
               increase in customer preference for perpetual licenses that
               involve payment of a single up-front fee and that are more
               typical in the computer software industry. While revenue
               generated from monthly lease licenses and noncancellable annual
               leases currently represents a portion of the Company's software
               license revenue, to the extent that perpetual license revenue
               continues to represent a significant percentage of total software
               license revenue, the Company's revenue in any period will
               increasingly depend on sales completed during that period.

               RISKS ASSOCIATED WITH ACQUISITIONS: The Company has consummated
               and may continue to consummate certain strategic acquisitions in
               order to provide increased capabilities to its existing products,
               enter new product and service markets or enhance its distribution
               channels. The ability of the Company to integrate the acquired
               businesses, including delivering sales and support, ensuring
               continued customer commitment, obtaining further commitments and
               challenges associated with expanding sales in particular markets
               and retaining key personnel, will impact the success of these
               acquisitions. If the Company is unable to properly and timely
               integrate the acquired businesses, there could be a materially

                                                                              31



               adverse effect on the Company's business, financial condition and
               results of operations.

               GENERAL ECONOMIC TRENDS: As the Company has grown, it has become
               increasingly subject to the risks arising from adverse changes
               in domestic and global economic conditions. As a result of the
               current economic slowdown, many companies are delaying or
               reducing technology purchases, which has had an impact on the
               Company's visibility into the closing of new business, as
               opposed to our recurring business. This slowdown has also
               contributed to, and may continue to contribute to, reductions in
               sales, longer sales cycles and increased price competition. Each
               of these items could adversely affect the Company's sales and
               net income in future periods.

               GENERAL CONTINGENCIES: The Company is subject to various
               investigations, claims and legal proceedings from time to time
               that arise in the ordinary course of its business activities.
               Each of these matters is subject to various uncertainties, and it
               is possible that some of these matters may be resolved
               unfavorably to the Company.

                                                                              32
