                                     PART I

ITEM 1. BUSINESS:

    International Business Machines Corporation (IBM) was incorporated in the
State of New York on June 16, 1911, as the Computing-Tabulating-Recording Co.
(C-T-R), a consolidation of the Computing Scale Co. of America, the Tabulating
Machine Co., and The International Time Recording Co. of New York. In 1924,
C-T-R adopted the name International Business Machines Corporation.

    IBM uses advanced information technology to provide customer solutions. The
company operates primarily in a single industry using several segments that
create value by offering a variety of solutions that include, either singularly
or in some combination, technologies, systems, products, services, software and
financing.

    Organizationally, the company's major operations comprise a Global Services
segment; three hardware product segments--Enterprise Systems, Personal and
Printing Systems and Technology; a Software segment; a Global Financing segment
and an Enterprise Investments segment. The segments are determined based on
several factors, including customer base, homogeneity of products, technology
and delivery channels.

    IBM offers its products through its global sales and distribution
organizations. The sales and distribution organizations have both a geographic
focus (in the Americas, Europe/Middle East/Africa, and Asia Pacific) and a
specialized and global industry focus. In addition, these organizations include
a global sales and distribution effort devoted exclusively to small and medium
businesses. IBM also offers its products through a variety of third party
distributors and resellers, as well as through its on-line channels.

    While the company's various proprietary intellectual property rights are
important to its success, IBM believes its business as a whole is not materially
dependent on any particular patent or license, or any particular group of
patents or licenses. IBM owns or is licensed under a number of patents, which
vary in duration, relating to its products. Licenses under patents owned by IBM
have been and are being granted to others under reasonable terms and conditions.
These protections may not prevent competitors from independently developing
products and services similar to or duplicative of the company's nor can there
be any assurance that these protections will adequately deter misappropriation
or improper use of the company's technology. Also, there can be no assurances
that IBM will be able to obtain from third parties the licenses it needs in the
future.

    IBM's businesses employ a wide variety of components, supplies and raw
materials from a substantial number of suppliers around the world. Certain of
the company's businesses rely on a single or limited number of suppliers,
although the company makes every effort to assure that alternative sources are
available if the need arises. The failure of the company's suppliers to deliver
components, supplies and raw materials in sufficient quantities and in a timely
manner could adversely affect the company's business.

    IBM's revenues are affected by such factors as the introduction of new
products, the length of the sales cycles and the seasonality of technology
purchases. As a result, the company's results are difficult to predict. These
factors historically have resulted in lower revenue in the first quarter than in
the immediately preceding fourth quarter.

    The value of unfilled orders is not a meaningful indicator of future
revenues from the company's product offerings due to the significant proportion
of revenue from services, the volume of products delivered from shelf
inventories, and the shortening of product delivery schedules. With respect to
the company's Global Services segment, in 2001 the company signed contracts
totaling $51 billion, which contributed to a services backlog at December 31,
2001 of $102 billion, compared with $85 billion at the end of 2000.

    The company operates in businesses that are subject to intense competitive
pressures. The company's businesses face a significant number of competitors,
ranging from Fortune 50 companies to

                                       1

an increasing number of relatively small, rapidly growing and highly specialized
organizations. The company believes that its combination of technology,
performance, quality, reliability, price and the breadth of products and service
offerings are important competitive factors.

    Intense competitive pressures could affect prices or demand for the
company's products and services, resulting in reduced profit margins and /or
loss of market opportunity. Unlike many of its competitors, the company has a
portfolio of businesses and must allocate resources across these businesses
while competing with companies that specialize in one or more of these product
lines. As a result, the company may not fund or invest in certain of its
businesses to the same degree that its competitors do and these competitors may
have greater financial, technical and marketing resources available to them than
the businesses against which they compete.

    The company operates in more than 150 countries worldwide and derives more
than half of its revenues from sales outside the United States. Changes in the
laws or policies of the countries in which the company operates could affect the
company's business in that country and the company's results of operations. The
company's results of operations also could be affected by economic and political
changes in those countries and by macroeconomic changes, including recessions
and inflation.

    The following information is included in IBM's 2001 Annual Report to
Stockholders and is incorporated herein by reference:

    Segment information and revenue by classes of similar products or
services--Pages 100 through 105.

    Financial information by geographic areas--Page 105.

    Amount spent during each of the last three years on research and development
activities--Page 91.

    Financial information regarding environmental activities--Page 88.

    The number of persons employed by the registrant--Page 69.

    The management discussion overview--Pages 55 and 56.

    Forward-looking and Cautionary Statements: Certain statements contained in
this Annual Report may constitute "forward-looking statements" within the
meaning of the Private Securities Litigation Reform Act of 1995 ("Reform Act").
The company may also make forward-looking statements in other reports filed with
the Securities and Exchange Commission, in materials delivered to stockholders
and in press releases. In addition, the company's representatives may from time
to time make oral forward-looking statements. Forward-looking statements provide
current expectations of future events based on certain assumptions and include
any statement that does not directly relate to any historical or current fact.
Words such as "anticipates," "believes," "expects," "estimates," "intends,"
"plans," "projects," and similar expressions, may identify such forward-looking
statements. The company assumes no obligation to update or revise any
forward-looking statements. In accordance with the Reform Act, set forth below
are cautionary statements that accompany those forward-looking statements.
Readers should carefully review these cautionary statements as they identify
certain important factors that could cause actual results to differ materially
from those in the forward-looking statements and from historical trends. The
following cautionary statements are not exclusive and are in addition to other
factors discussed elsewhere in this Annual Report, in the company's filings with
the Securities and Exchange Commission or in materials incorporated therein by
reference.

    New Products and the Pace of Technological Change: The company's results of
operations depend on the continued successful development and marketing of new
and innovative products and services. The development of new products and
services requires significant capital investments by the company's various
businesses and the success of these products and services depends on their
acceptance by customers and business partners. Further, the company's businesses
are characterized by rapid technological changes and corresponding shifts in
customer demand, resulting in unpredictable product transitions and shortened
life cycles and increasing emphasis on being first to market with new products
and services.

                                       2

    There can be no assurance that the company will successfully introduce new
products and services, that these products and services will be accepted by
customers, or that the company's businesses will recoup or realize a return on
their capital investments. In addition, from time to time the company may
experience difficulties or delays in the development, production or marketing of
new products and services.

    Volatility of Stock Prices: The company's stock price is affected by a
number of factors, including quarterly variations in results, the competitive
landscape, general economic and market conditions and estimates and projections
by the investment community. As a result, like other technology companies, the
company's stock price is subject to significant volatility.

    Dependence on and Compensation of Key Personnel: Much of the future success
of the company depends on the continued service and availability of skilled
personnel, including technical, marketing and staff positions. Experienced
personnel in the information technology industry are in high demand and
competition for their talents is intense. There can be no assurance that the
company will be able to successfully retain and attract the key personnel it
needs. Many of the company's key personnel receive a total compensation package
that includes stock options and other equity awards. New regulations, volatility
in the stock market and other factors could diminish the value of the company's
equity awards, putting the company at a competitive disadvantage or forcing the
company to use more cash compensation.

    Currency and Customer Financing Risks: The company derives a significant
percentage of its non-U.S. revenues from its affiliates operating in local
currency environments and its results are affected by changes in the relative
values of non-U.S. currencies and the U.S. dollar. Further, inherent in the
company's customer financing business are risks related to the concentration of
credit risk and the creditworthiness of the customer, interest rate and currency
fluctuations on the associated debt and liabilities and the determination of
residual values. The company employs a number of strategies to manage these
risks, including the use of derivative financial instruments. Derivatives
involve the risk of non-performance by the counterparty. In addition, there can
be no assurance that the company's efforts to manage these risks will be
successful.

    Distribution Channels: The company offers its products directly and through
a variety of third party distributors and resellers. Changes in the financial or
business condition of these distributors and resellers could subject the company
to losses and affect its ability to bring its products to market.

    Acquisitions and Alliances: The company has made and expects to continue to
make acquisitions or enter into alliances from time to time. Acquisitions and
alliances present significant challenges and risks relating to the integration
of the business into the company, and there can be no assurances that the
company will manage acquisitions and alliances successfully.

ITEM 2. PROPERTIES:

    At December 31, 2001, IBM's manufacturing and development facilities in the
United States had aggregate floor space of 40.8 million square feet, of which
31.5 million was owned and 9.3 million was leased. Of these amounts,
2.4 million square feet was vacant and 1.9 million square feet was being leased
to non-IBM businesses. Similar facilities in 15 other countries totaled
15.2 million square feet, of which 10.7 million was owned and 4.5 million was
leased. Of these amounts, 0.6 million square feet was vacant and 0.9 million
square feet was being leased to non-IBM businesses.

    Although improved production techniques, productivity gains and
infrastructure reduction actions have resulted in reduced manufacturing floor
space, continuous upgrading of facilities is essential to maintain technological
leadership, improve productivity, and meet customer demand. For additional
information on expenditures for plant, rental machines and other property, refer
to "Investments" on pages 65 and 66 of IBM's 2001 Annual Report to Stockholders
which is incorporated herein by reference.
