Segment Information

The company’s major operations consist of five business segments: Global Technology Services, Global Business Services, Software, Systems and Technology and Global Financing. The segments represent components of the company for which separate financial information is available that is utilized on a regular basis by the chief executive officer in determining how to allocate resources and evaluate performance. The segments are determined based on several factors, including client base, homogeneity of products, technology, delivery channels and similar economic characteristics.

Information about each segment’s business and the products and services that generate each segment’s revenue is located in the “Description of Business” section on pages 26 to 31, and in “Segment Details,” on pages 23 and 24 in the Management Discussion.

Segment revenue and pre-tax income include transactions between the segments that are intended to reflect an arm’s-length, market-based transfer price. Systems and software that are used by Global Technology Services in outsourcing engagements are primarily sourced internally from Systems and Technology and Software. For providing IT services that are used internally, Global Technology Services and Global Business Services recover cost, as well as a reasonable fee, that is intended to reflect the arm’s-length value of providing the services. The Global Services segments enter into arm’s-length loans at prices equivalent to market rates with Global Financing to facilitate the acquisition of equipment used in services engagements. All internal transaction prices are reviewed annually, and reset if appropriate.

The company utilizes globally integrated support organizations to realize economies of scale and efficient use of resources. As a result, a considerable amount of expense is shared by all of the segments. This shared expense includes sales coverage, certain marketing functions and support functions such as Accounting, Treasury, Procurement, Legal, Human Resources, and Billing and Collections. Where practical, shared expenses are allocated based on measurable drivers of expense, e.g., head count. When a clear and measurable driver cannot be identified, shared expenses are allocated on a financial basis that is consistent with the company’s management system, e.g., advertising expense is allocated based on the gross profits of the segments. A portion of the shared expenses, which are recorded in net income, are not allocated to the segments. These expenses are associated with the elimination of internal transactions and other miscellaneous items.

The following tables reflect the results of operations of the company’s segments consistent with the management and measurement system utilized within the company. Performance measurement is based on pre-tax income. These results are used, in part, by senior management, both in evaluating the performance of, and in allocating resources to, each of the segments.

Immaterial Items

Investment in Equity Alliances and Equity Alliances Gains/(Losses)

The investments in equity alliances and the resulting gains and (losses) from these investments that are attributable to the segments did not have a material effect on the financial position or the financial results of the segments.

Segment Assets and Other Items

Global Technology Services assets are primarily plant, property and equipment including the assets associated with the outsourcing business, accounts receivable, goodwill, acquired intangible assets, deferred services arrangement transition costs and maintenance parts inventory. Global Business Services assets are primarily goodwill and accounts receivable. Software assets are mainly goodwill, acquired intangible assets and accounts receivable. Systems and Technology assets are primarily plant, property and equipment, goodwill, manufacturing inventory and accounts receivable. Global Financing assets are primarily financing receivables and fixed assets under operating leases.

To ensure the efficient use of the company’s space and equipment, several segments may share plant, property and equipment assets. Where assets are shared, landlord ownership of the assets is assigned to one segment and is not allocated to each user segment. This is consistent with the company’s management system and is reflected accordingly in the table on page 137. In those cases, there will not be a precise correlation between segment pre-tax income and segment assets.

Similarly, the depreciation amounts reported by each segment are based on the assigned landlord ownership and may not be consistent with the amounts that are included in the segments’ pre-tax income. The amounts that are included in pre-tax income reflect occupancy charges from the landlord segment and are not specifically identified by the management reporting system. Capital expenditures that are reported by each segment also are consistent with the landlord ownership basis of asset assignment.

Global Financing amounts for interest income and interest expense reflect the interest income and interest expense associated with the Global Financing business, including the intercompany financing activities discussed on page 24, as well as the income from investment in cash and marketable securities. The explanation of the difference between cost of financing and interest expense for segment presentation versus presentation in the Consolidated Statement of Earnings is included on page 66 of the Management Discussion.
