PORTFOLIO MANAGEMENT, INVESTMENT ACCOUNTING

CAMRA 2000

The Company's Complete Asset Management, Reporting and Accounting ("CAMRA 2000")
software supports the integrated management of asset portfolios by investment
professionals operating across a wide range of institutional investment
entities. CAMRA 2000 is a 32-bit, multi-user, integrated solution tailored to
support the entire portfolio management function, and includes features to
execute, account for, and report on all typical securities transactions.

     CAMRA 2000 is designed to account for all the activity of the investment
operation and to continually update investment information through the
processing of day-to-day securities transactions. The product accounts for both
transactions and holdings and stores the results of most accounting calculations
in its open, relational database, thereby providing user-friendly, flexible data
access as well as supporting data warehousing. In addition to storing
transactions and holdings data on securities, cash, and foreign exchange forward
contracts, CAMRA 2000 also stores data on custodians, brokers and broker
budgets, analytical information,

                                     Page 3
<PAGE>   5

general ledger entries, alternative accounting basis, tax information, and other
aspects of the investment operation. To facilitate further automation of such
extensive stored data, the Company has developed interface capabilities for
smooth information exchange with custodian banks, data providers, and analytic
data services.

Other CAMRA 2000 features include the following:

Comprehensive Accounting and Reporting Capabilities.  CAMRA 2000 supports four
distinct yet interrelated accounting bases--GAAP, statutory, management, and
tax--and has the flexibility to provide multiple alternative accrual methods,
multiple sales methods, average cost or tax lot accounting, and multiple
amortization methods.

Support of Trading Transactions.  CAMRA 2000 supports a wide variety of
investment and accounting transactions, ranging from buy and sell to short and
cover, swap, put, call, redemption, return of capital, settlement, account
transfer, and portfolio transfer. All transactions are recorded on a real-time
basis, permitting immediate enterprise-wide access to the most current portfolio
information by authorized users.

Multi-currency Processing.  CAMRA 2000 automatically calculates transaction and
translation values in accordance with applicable accounting and industry
conventions, supports calculation of market, accounting, and foreign exchange
gains and losses, and provides a full foreign exchange trading capability with
forward pricing, while taking into account such critical parameters as global
calendars (with weekends and holidays defined by countries), multiple-based
currencies, and required rounding techniques.

Regulatory Compliance.  CAMRA 2000 includes standard reports to meet the annual
and quarterly regulatory reporting requirements of insurance organizations as
promulgated by the National Association of Insurance Commissioners (NAIC). CAMRA
2000 also supports regulatory reporting requirements of various other regulatory
agencies such as the Securities and Exchange Commission and the Office of the
Comptroller of the Currency.

Integrated Modules.  CAMRA 2000 is designed to facilitate seamless integration
with its software modules. Modules to CAMRA 2000 are available for performance
measurement using computations consistent with Association for Investment
Management and Research (AIMR) standards, pre- and post-trade compliance
monitoring, net asset value computations for mutual funds, optimization of
trading in mortgage-backed securities on a to-be-announced (TBA) basis, client
fee billing, portfolio rebalancing, and interfacing with various products of
Bloomberg Trade Book, Open Bloomberg, Interactive Data Corporation, and other
analytic data services.

CAMRA XE (in beta release)

SS&C's CAMRA XE is the portfolio management and accounting component of the
Company's recently introduced XE for Asset Management platform. This platform

allocation data from outside sources as well as within the SS&C application
environment.

Total Return 2000

Total Return 2000 is a portfolio management and partnership accounting system
oriented toward the hedge fund and private wealth markets. It is a
multi-currency system which, like CAMRA 2000, is designed to provide securities
accounting and reporting for businesses with high transaction volumes.
Partnership accounting, including the generation of tax forms 1065 and K-1, are
provided through Total Return 2000's TR1065 module. Total Return 2000 also
incorporates a comprehensive general ledger. Performance measurement using
computations consistent with AIMR standards is also provided through a module to
the system. Other modules to Total Return 2000 provide for tax reporting and
trust reporting. Total Return 2000 also has interfaces with brokers, pricing
services, data services, and front-end trading systems.

multi-user, client/server, Windows '95 or Windows NT operating systems.

TRADE ORDER MANAGEMENT

Antares 2000

Antares 2000 is a comprehensive, real-time, event-driven trading and profit and
loss reporting system designed to integrate trade modeling with trade order
management. Antares 2000 also offers pre-trade compliance, "what-if" analysis,
and FIX connectivity. Modeling scenarios, including trader-defined formulas, can
be customized and stored in a familiar spreadsheet environment. Antares 2000 is
designed to transfer data seamlessly from modeling scenarios to trade orders. In
Antares 2000, trades can be managed in the multiple steps of trade ordering,
filling the order, and approving the trade, or recorded in a single step.
Antares 2000 can also allocate trades across accounts at any step in the
process.

     Trade blotters in Antares 2000 can be customized depending on client,
product type, or trader. Full position accounting is provided across all types
of securities. Antares 2000 also accepts real-time pricing updates and can
display real-time positions and profit and loss statements. Portfolio
rebalancing can be set to occur automatically. As Antares 2000 uses an open
relational database, customized reporting is supported through its own report
writing facilities, or through other third-party reporting tools. Antares 2000
also includes functionality to automate the processing of options, futures, and
forward currency contracts.

     For some financial institutions, the Antares 2000 trading system may serve
as a comprehensive, stand-alone investment management system. For financial
institutions with more accounting and historical reporting requirements, Antares
2000 may serve as the front-end trading system connected to CAMRA 2000, Total
Return 2000, AdvisorWare 2000 or other portfolio management investment
accounting systems.

Antares XE (in beta release)

Antares XE is the trade order management component to the Company's recently
released XE for Asset Management platform. This platform incorporates
Microsoft's DNAfs architecture and development strategy, and uses XML-based
messaging and workflow technology for processing trade order and allocation data
from outside sources as well as within the SS&C application environment.

ASSET/LIABILITY MANAGEMENT

PTS 2000

PTS 2000 provides an economic model of insurance assets and liabilities,
generating option-adjusted cash flows to reflect the complex sets of options and
covenants frequently encountered in insurance contracts or comparable
agreements. PTS 2000 includes the following features:

Large-Scale Corporate Simulation Models.  The Company and certain significant
clients have implemented a number of complex models of whole-company financial
performance. Unlike simpler systems, PTS 2000 maintains an internal architecture
patterned after the structure of insurance companies themselves, making
full-scale corporate models practical. Such corporate models are used to
facilitate capital structure decisions, revealing and measuring overall
financial performance, and guiding overall risk management practice.

Option Pricing.  The PTS 2000 option-pricing model provides option-adjusted
valuation of assets and liabilities under a consistent conceptual framework. The
PTS 2000 option pricing model explicitly considers interest-sensitive embedded
options, providing valid interest rate risk analysis, using price behavior
curves that graphically depict asset/liability performance over shifts in the
interest rate term structure.

Macro Pricing.  The Company's proprietary Macro-Pricing algorithm recognizes the
complex relationships within contemporary financial intermediaries and provides
a matrix of possible product and production quota options in conformity with the
profit expectations of the client.

DYNAMIC FINANCIAL ANALYSIS

Finesse 2000

The Company's Finesse 2000 system is a forecasting application that brings the
principles of Dynamic Financial Analysis (DFA) to the complex environment of the
property/casualty insurance industry. A financial simulation tool designed to
balance the dynamics of financial accounting, economic value, and risk, Finesse
2000 is unique in its ability to express forecasts in real-world terms: ROE,
EPS, GAAP earnings, Capital Ratios, and the like--performance metrics used on a
daily basis in the executive suite.

     Finesse 2000 was conceived as a business simulation platform fully
integrating the asset and liability sides of the balance sheet. Because Finesse
2000 handles the complex interactions between asset and liability cash flows,
Finesse 2000 functions as a superior forecasting tool, generating 5-year pro
forma balance sheets, income and cash flow statements. By integrating capital
market effects onto both asset and liability cash flows, results remain
"in-sync" as they cascade through the Finesse 2000 Corporate Model.

     Finesse 2000 is a simulation tool with the primary goal of projecting
financial results--hundreds or even thousands of times.

     By projecting financials many times over, clients can cover the likely
range of events, whether they are interest rate movements, loss ratios,
production levels, or any other item of variability. Using Finesse 2000's unique
presentation methods, clients can distill a wide range of results into
actionable language.

LOAN MANAGEMENT

LMS 2000

LMS 2000 enables mortgage professionals to process, analyze, and report on a
comprehensive basis, information regarding their mortgage loan portfolios. LMS
2000 is a 32-bit, multi-user, integrated solution operating on a client/server
platform, which eliminates the need for separate, independent systems within the
mortgage loan area. LMS 2000, which can be integrated with data stored in the
Company's CAMRA 2000 and PTS 2000 products, provides the following features:

Application and Commitment Processing.  LMS 2000 supports the processing of
commercial and residential mortgage loans, providing on-line access to critical
evaluative information, including credit history, appraisals, ratio, broker
information, duration, convexity, average life and discounted cash flow
valuation, permitting loan recommendations to be generated quickly,
consistently, and easily.

                                     Page 6
<PAGE>   8

Accounting and Servicing Support.  LMS 2000 supports accurate and consistent
servicing of loans, including general ledger entries at the sub-portfolio level,
with a direct interface to the corporate general ledger. LMS 2000 also maintains
appraisals and operating statements at the proper level to support loan and
portfolio management.

Comprehensive Reports.  LMS 2000 generates and supports a wide range of
accounting, servicing, and management reports. All reports can be viewed
on-line, downloaded or printed.

REO.  LMS 2000 provides a smooth transition from a loan to an equity asset,
establishes/monitors budgets, maintains depreciation records, and processes
REO-specific transactions.

Executive Summary.  LMS 2000 SnapShots captures a complete overview of a
selected portfolio, making essential information immediately available. LMS 2000
SnapShots also exports into Microsoft Excel or Lotus.

CONSULTING SERVICES

Building upon the capability and flexibility of its software products, the
Company offers a range of professional services to assist clients in
implementing the Company's software products and meeting their portfolio
management needs. To facilitate successful product implementation, the Company's
consultants assist clients with initial installation of a system, conversion of
the client's historical data, and ongoing training and support. The Company's
team works closely with the client to ensure smooth transition and operation of
the Company's systems. The Company believes its commitment of dedicated
professionals to facilitate the transition process strengthens its relationship
with the client, provides the Company with valuable information regarding client
requirements, and offers the opportunity for sales of additional Company
products and services to the client. The Company's consultants have a broad
range of experience in the financial services industry and include certified
public accountants, chartered financial analysts, mathematicians, and
professionals from the asset management, real estate, investment, insurance, and
banking industries. The Company believes its commitment to professional services
facilitates the adoption of the Company's software products across its target
markets.

SS&C DIRECT

For those clients seeking an Application Service Provider/Business Process
Outsourcing (ASP/BPO) solution for portfolio accounting, reporting and analysis
functions, the Company also provides comprehensive ASP/BPO services through its
SS&C Direct operating unit. The Company's consultants initially work with a
client to research and evaluate data sources, implement custodian and pricing
interfaces and determine

                                     Page 7
<PAGE>   9

reporting requirements and timing. The Company provides its clients with
accurate, processed data via Internet or direct, real-time connections, enabling
investment professionals to spend their time analyzing data and making
investment decisions rather than managing the back-office investment operations.
The features of the Company's ASP/BPO services include: (i) customized access
rights to provide on-line, real-time access on a per-client basis; (ii) regular
holdings reports, also available on-line, and complete regulatory support; (iii)
disk mirroring, daily back-up of the system and other data protection measures;
and (iv) disaster recovery hot site services.

PRODUCT SUPPORT

The Company believes its high level of service and support is critical to its
success, and an important competitive advantage. Further, the Company believes a
close and active service and support relationship is important to client
satisfaction, and provides the Company with important information regarding
evolving client requirements. The Company provides each of its significant
clients with a dedicated client support team, organized by industry and by
function, whose primary responsibility is to resolve questions and concerns. In
addition, the Company provides direct telephone support during extended business
hours. Additional hours are available during peak periods, and the Company uses
the Internet, electronic bulletin boards and other forms of electronic data
distribution that provide clients with the latest information regarding its
products. The Company uses Applix technology to log and track issues and
questions, and Webex for on-line diagnostics. The Company also provides periodic
maintenance releases of licensed software to its clients, as well as regulatory
updates (generally during the fourth quarter), to enable them to meet industry
reporting obligations and other processing requirements as they evolve. The
Company's service and support activities are supplemented by comprehensive
training, including a comprehensive Center of Excellence client certification
program, which provides certification classes in the Company's products.

CLIENTS

The Company's clients include a wide range of financial institutions and other
organizations that require a full range of information management and analysis,
accounting, actuarial, reporting, and compliance software on a timely and
flexible basis, and include asset managers, insurance companies, banks,
corporate treasuries, hedge funds, family offices, real estate asset managers,
and government agencies. The Company provides products and services to more than
5,500 organizations worldwide.

SALES AND MARKETING

The Company believes a direct sales organization is essential to the successful
implementation of its business strategy, given the complexity and importance of
the operations and information the Company's products are designed to manage,
and the extensive regulatory and reporting requirements of its clients. The
Company's dedicated direct sales and support staff, which is supplemented by
extensive ongoing product and sales training, is organized by business unit and
situated in the Company's various sales offices. The Company also uses
telemarketing to support sales of its real estate equity products.

     The Company's marketing personnel are responsible for evaluating and
developing market opportunities and providing sales support. The Company's
marketing activities include generation of client leads, targeted direct mail
campaigns, Internet marketing, seminars, advertising, trade shows, conferences,
and public relations efforts. The marketing department also supports the sales
force with appropriate documentation or electronic materials for use during the
sales process.

PRODUCT DEVELOPMENT; RESEARCH AND DEVELOPMENT; BACKLOG

The Company believes it must introduce new products and features into the market
on a regular basis to maintain its competitive advantage. To meet these goals,
the Company uses multidisciplinary teams of highly trained finance, accounting,
mathematical, actuarial, software, and investment personnel, and has invested
heavily in developing a comprehensive product analysis process to meet rigorous
requirements for product functionality and quality across its target markets.

                                     Page 8
<PAGE>   10

     The Company's research and development engineers work closely with the
Company's marketing and support personnel to assure product evolution reflects
developments in the marketplace and trends in client requirements. Historically,
the Company has issued a major functional release of its core products during
the second or third quarter of each fiscal year, including functional
enhancements, as well as an annual fourth quarter release to reflect evolving
regulatory changes in time to meet clients' year-end reporting requirements.

     Although the Company historically has met its scheduled dates for product
releases and enhancements, software development is characterized by
unanticipated delays, and there can be no assurance that the Company will be
able to maintain future scheduled release dates as planned. Further, there can
be no assurance that the Company's new product releases and product enhancements
will adequately address the needs of the marketplace or will not contain "bugs"
which could cause delays in product introduction or shipments or, if discovered
in the future, require modification of the Company's products.

     As of December 31, 1999, the Company's research and development staff
consisted of 169 employees. The Company's total expenses for research and
development, excluding purchased in-process research and development, for the
years ended December 31, 1997, 1998, and 1999 were $12.0 million, $20.1 million,
and $20.7 million, respectively.

     Backlog is not a significant factor in the Company's business.

COMPETITION

The market for financial services software is competitive, rapidly evolving, and
highly sensitive to new product introductions and marketing efforts by industry
participants. The market is also highly fragmented and served by numerous firms,
many of which serve only their respective local markets or specific customer
types, and much of the Company's competition stems from information systems or
timesharing services developed and serviced internally by the MIS departments of
financial services firms. The Company currently faces direct competition in
various segments of the financial services industry from Thomson Financial,
SunGard Data Systems, Inc., Princeton Financial Systems (a subsidiary of State
Street Bank and Trust Company), Financial Models Company Inc., DST Systems,
Inc., McCracken Financial Software, Tillinghast-Towers Perrin, and Advent
Software, Inc. The Company believes none of its competitors currently competes
against it in all of its target industry segments, although there can be no
assurance that one or more may not compete against the Company in the future in
additional industry segments. Many of the Company's current and potential future
competitors have significantly greater financial, technical, and marketing
resources, generate higher revenues, and have greater name recognition than does
the Company. There can be no assurance that the Company's current or potential
competitors will not develop products comparable or superior to those developed
by the Company or adapt more quickly than the Company to new technologies,
evolving industry trends, or changing client requirements. It is also possible
that alliances among competitors may emerge and rapidly acquire significant
market share. Increased competition may result in price reductions, reduced
gross margins, and loss of market share, any of which would materially adversely
affect the Company's business, financial condition, and results of operations.

     The Company believes the principal competitive factors in its industry
include product performance and functionality, ease of use, scalability, ability
to integrate external data sources and processing systems, product and company
reputation, client service and support, and price. Although the Company believes
it currently competes effectively with respect to such factors, there can be no
assurance that the Company will be able to maintain its competitive position
against current and potential competitors.

PROPRIETARY RIGHTS

The Company primarily relies on a combination of copyright, trademark, and trade
secret laws and license agreements to establish and protect proprietary rights
of its products. The source code for the Company's products is protected as both
a trade secret and an unpublished copyrighted work. In addition, the Company
generally enters into confidentiality and/or license agreements with its
employees, distributors, clients, and potential clients and limits access to,
and distribution of, its software, documentation, and other proprietary
information. Despite these precautions, it may be possible for a third party to
copy or otherwise obtain and use

                                     Page 9
<PAGE>   11

the Company's products or technology without authorization or to develop similar
technology independently. In addition, effective copyright and trade protection
may be unavailable or limited in certain foreign countries. In January 1996, the
Company licensed the use of certain of its source code to General American Life
Insurance Company and Conning Asset Management Company, affiliates of certain
stockholders of the Company.

     Because the software development industry is characterized by rapid
technological change, the Company believes factors such as technological and
creative skills of its personnel, new product developments, frequent product
enhancements, name recognition, and reliable service and support are more
important to establishing and maintaining a leadership position than legal
protections of its technology.

EMPLOYEES

As of December 31, 1999, the Company had 551 full-time employees, consisting of
169 employees in research and development, 165 employees in consulting and
services, 89 employees in sales and marketing, 82 employees in client support
and 46 employees in finance and administration. Of the total, 98 employees are
in the Company's international operations. None of these employees is covered by
any collective bargaining agreements. The Company believes its relationship with
its employees is good. The future success of the Company will depend upon its
ability to attract and retain qualified personnel. Competition for such
personnel is often intense, and there can be no assurance that the Company will
be able to attract and retain adequate numbers of qualified personnel in the
future.

ITEM 2. PROPERTIES

The Company leases its corporate offices, consisting of 73,000 square feet of
office space, in Windsor, Connecticut. The initial lease term expires in 2008,
and the Company has the right to extend the lease for one additional term of
five years. In support of direct sales and support operations, the Company
utilizes facilities and offices in thirteen locations in the United States and
Canada and also has offices in London, England; Amsterdam, Netherlands; Kuala
Lumpur, Malaysia; and Tokyo, Japan.

ITEM 3. LEGAL PROCEEDINGS

On May 7, 1999, the Company announced that it had entered into an agreement that
provides for the settlement of the consolidated securities class action lawsuit
pending against the Company. The settlement provides that all claims against the
Company, certain of its officers and directors and underwriters will be
dismissed. Under the terms of the settlement, in exchange for the dismissal and
release of all claims, the Company paid to the class $7.5 million in cash,
together with shares of Common Stock of the Company valued at $1.3 million. The
Company recorded a charge of $9.3 million, including legal fees, in the quarter
ended June 30, 1999.

     From time to time, the Company is subject to certain legal proceedings and
claims that arise in the normal course of its business. In the opinion of
management, the Company is not party to any litigation that it believes could
have a material effect on the Company or its business.

ITEM 4. SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

The Company did not submit any matters to a vote of security holders during the
fourth quarter of the fiscal year covered by this report.

     There were 62 stockholders of record of the Company's Common Stock as of

stock. The Company currently intends to retain earnings, if any, to support its
growth strategy and does not anticipate paying cash dividends in the foreseeable
future. Payment of future dividends, if any, will be at the discretion of the
Company's Board of Directors after taking into account various factors,
including the Company's financial condition, operating results, current and
