Segment Reporting [Abstract]

SEGMENT INFORMATION

16.    SEGMENT INFORMATION

Our operating segments were determined based primarily on how the Chief Operating Decision Maker (“CODM”), President and Chief Executive Officer, views and evaluates our operations. 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.

The CODM is regularly provided with and reviews segment revenues and segment income from operations to support decision-making, set strategic goals, allocate resources, and evaluate each segment’s progress against the company’s plan. The CODM also reviews and approves budgets, including capital expenditures, at the segment level. The segment results are not necessarily in conformity with GAAP and exclude items such as share-based compensation expense, amortization of acquisition-related balances, acquisition and integration costs, restructuring costs, interest income, interest expense, and other items.

A significant portion of the segments’ expenses arise from allocated corporate charges, as well as expenses related to our centralized sales force, and service, marketing and technology functions that we have historically provided to the segments in order to realize economies of scale and to efficiently use resources. Corporate charges include legal, accounting, real estate, insurance services, information technology services, treasury, and other corporate infrastructure expenses. Segment allocations are 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. Newly acquired businesses are not allocated these charges until integrated into our shared services and corporate infrastructure.

Descriptions of our two reportable segments are as follows:

The Communications Solutions Group (“CSG”) serves customers spanning the global commercial communications and aerospace, defense, and government end markets. The group’s solutions consist of electronic design and test software, instrumentation, systems, and related services. These solutions are used in the design, simulation, validation, manufacturing, installation, and optimization of communication systems in wireless, wireline (data center networking), enterprise, and aerospace, defense, and government end markets. Our recent acquisition of Spirent adds wireless network test and assurance and positioning technology solutions to our portfolio, complementing our design, validation, and performance offerings to deliver end-to-end solutions to our customers.

The Electronic Industrial Solutions Group (“EISG”) serves customers across a diverse set of end markets focused on automotive and energy, semiconductor solutions, and general electronics. The group's solutions consist of electronic design, test and simulation software, instrumentation, systems, computer-aided engineering solutions, and related services. These solutions are used in the design, simulation, validation, manufacturing, installation, and optimization of electronic equipment.

The following tables reflect the results of our reportable segments and significant segment expenses as defined above.

Segment assets include goodwill and gross other intangible assets, accounts receivable, inventory, property, plant and equipment, and other assets. Unallocated assets primarily consist of cash and cash equivalents, deferred tax assets, long-term investments, accumulated amortization of other intangible assets, pension assets, and other assets. The increase in segment assets for the year ended October 31, 2025 was primarily due to additions in assets acquired as part of the 2025 acquisitions. See Note 2, “Acquisitions,” for additional information.

The following tables present summarized information for revenue and long-lived assets by country. Revenues from external customers are generally attributed to countries based upon the customer's location.
