PART I

ITEM 1. BUSINESS

FactSet Research Systems Inc. (the “Company” or “FactSet”) is a provider of global financial and economic information, including fundamental data on tens of thousands of companies worldwide. Combining more than 200 databases into its own dedicated online service, the Company also provides the tools to download, combine and manipulate the data for investment analysis.

FactSet receives financial information from over 50 database suppliers. When possible, the Company seeks to maintain contractual relationships with a minimum of two database providers for each type of financial data. Contracts with database suppliers are generally renewable annually and may often be terminated on one year’s notice. Many of the database suppliers are in direct competition with each other and in some cases, with FactSet. Fees for data are either billed directly to FactSet or its clients. Financial data fees billed to the Company are on a fixed or royalty (per client) cost basis.

Through FactSet’s exclusive proprietary communication and software tools, clients obtain access to the Company’s mainframe centers using the Company’s private wide area network. FactSet’s wide area network provides a high-speed direct link between the client’s local network and the vast data libraries and powerful applications found on the Company’s mainframes. For an annual subscription fee, clients purchase the right to access the FactSet system through the private wide area network.

An essential part of the Company’s strategy to maintain long-term client relations involves both consulting services and client training. Thru the Company’s call center system and customer relationship management system, consulting and sales teams gain improved intelligence about client activities and are able to develop better tools to service them. Clients are highly encouraged to take part in the training programs, conducted either at the client’s location or a FactSet office. These training programs are designed to give clients a comprehensive understanding of FactSet’s service which is in addition to technical support available around the clock.

FactSet competes in the financial information services industry, which includes both large and well-capitalized companies, as well as smaller, niche firms. Domestic and international competitors include market data suppliers, news and information providers and many of the database providers that supply the Company with financial information included in the FactSet system. Competitors and competitive products in the United States include online, CD-ROM, and Internet database suppliers and integrators and their applications such as The Thomson Corporation, FAME, Barra Inc., Capital IQ Inc., COMPUSTAT, (a product of Standard & Poors, a division of The McGraw-Hill Companies), and Multex.com Inc. Datastream, owned by The Thomson Corporation, and RIMES are the Company’s primary international competitors. These competitors offer products or services which are similar to those provided by FactSet and in some instances at a lower price.

During fiscal 2002, FactSet continued to invest in its investment banking and investment management products. Some of the investments made in the Company’s investment banking products included an overhaul of FactSet’s EDGAR SEC filings application and the release of an application to allow research analysts to annotate stock charts with estimate revisions as mandated by the SEC. In fiscal 2002, the Company’s suite of portfolio analysis products continued to gain wide acceptance within the investment management industry. The number of clients subscribing to the Company’s Portfolio Analytics product grew 28% to 320 clients from August 31, 2001. Major enhancements to the Style, Performance and Risk product (“SPAR”) have resulted in an increased subscription rate for the returns-based analysis tool. The Company also experienced additional client subscriptions to its Portfolio Optimization product, which is the result of FactSet’s partnership with Northfield Information Services, Inc.

In June 2002, the Company released Marquee, its real-time quote product. Marquee users can access real-time quotes from all major US exchanges, as well as a variety of newswires and Wall Street research reports. This application includes the ability to integrate FactSet-hosted client portfolio holdings into a view that calculates real-time portfolio performance. Also in fiscal 2002, FactSet completed the integration of its LionShares acquisition, which occurred in fiscal 2001. LionShares is a division of FactSet that collects and distributes institutional holdings information. During fiscal 2002, LionShares extended its coverage to include European mutual funds. Additionally, FactSet has entered into several relationships as a bulk content supplier of this information to selected third-party financial information vendors. Portfolio Analysis 2.0, the Company’s holdings-based analysis product, also features LionShares data, to allow clients to compare their portfolios with portfolios of competitors.

Data Central, the Company’s application that facilitates the process of uploading, maintaining and integrating client data on the FactSet system, was also released in fiscal 2002. This application allows investment management clients to upload daily portfolio holdings information to the FactSet system in order to populate the reports generated in Portfolio Analysis. Equity research clients archive earnings estimate models using Data Central. Investment bankers also use the application to store the financial data driving the comparable analyses they perform to value companies for corporate finance transactions.

In November 2001, the Company opened its new data center in Manchester, New Hampshire to replace the New York data center. The 12,000 square foot state-of-the-art facility includes 7,500 square feet of conditioned data center space. The new facility has enough capacity to serve the Company’s needs for years to come and offers complete redundancy to the existing data center at FactSet’s Greenwich, Connecticut headquarters.

The number of employees of FactSet and its subsidiaries totaled 700 as of November 8, 2002. At August 31, 2002, the Company had 685 employees, compared to 612 at August 31, 2001.
