SEGMENT INFORMATION
15. SEGMENT INFORMATION

Description of segments. We provide core electronic measurement solutions to the communications and electronics industries.

We have two reportable operating segments, measurement solutions and customer support and services. The two operating segments were determined based primarily on how the chief operating decision maker views and evaluates our operations. Operating results are regularly reviewed by the chief operating decision maker to make decisions about resources to be allocated to the segment and to assess its performance. Other factors, including market separation and customer specific applications, go-to-market channels, products and services and manufacturing are considered in determining the formation of these operating segments.

A description of our two reportable segments is as follows:

Our measurement solutions business provides electronic measurement instruments and systems with related software and software design tools that are used in the design, development, manufacture, installation, deployment and operation of electronics equipment. We provide startup assistance, consulting, optimization and application support throughout the customer's product lifecycle.

The customer support and services business provides repair and calibration services for our installed base measurement solutions customers and facilitates the resale of used equipment. Our customer support and services business enables our customers to maximize the value from their electronic measurement equipment and strengthens customer loyalty. Providing these services assures a high level of instrument performance and availability while minimizing the cost of ownership and downtime.

A significant portion of the segments' expenses arise from shared services and infrastructure that we have historically provided to the segments in order to realize economies of scale and to efficiently use resources. These expenses, collectively called corporate charges, include costs of centralized research and development, legal, accounting, real estate, insurance services, information technology services, treasury and other corporate infrastructure expenses. Charges are allocated to the segments, and the allocations have been determined on a basis that we consider to be a reasonable reflection of the utilization of services provided to or benefits received by the segments.

The following tables reflect the results of our reportable segments under our management reporting system. These results are not necessarily in conformity with U.S. GAAP. The performance of each segment is measured based on several metrics, including income from operations. These results are used, in part, by the chief operating decision maker in evaluating the performance of, and in allocating resources to, each of the segments.

The profitability of each of the segments is measured after excluding restructuring-related charges, share-based compensation expense, investment gains and losses, interest expense, acquisition and integration costs, separation-related costs, amortization of intangibles and other items as noted in the reconciliations below.
