Segment Reporting [Abstract]

Segment Reporting

(9) Segment Reporting

We are organized into two business segments, Enterprise Service Management (ESM) and Mainframe Service Management (MSM). The ESM segment derives its revenue from our service support, service assurance and service automation solutions, along with professional services revenue derived from consulting, implementation, integration and educational services related to our software products. The MSM segment derives its revenue from products for mainframe database management, monitoring and automation, middleware management, enterprise scheduling and output management solutions.

Segment performance is measured based on segment operating income, reflecting segment revenue less direct and allocated indirect segment operating expenses. Direct segment operating expenses primarily include cost of revenue, selling and marketing, research and development and general and administrative expenses that can be specifically identified to a particular segment and are directly controllable by segment management, while allocated indirect segment operating expenses primarily include indirect costs within these operating expense categories that are not specifically identified to a particular segment or controllable by segment management. The indirect operating expenses are allocated to the segments based on budgeted bookings, revenue and other allocation methods that management believes to be reasonable. Our measure of segment operating income does not include the effect of share-based compensation expenses, amortization of acquired technology and other intangible assets or the costs associated with severance, exit costs and related charges, which are collectively included in unallocated operating expenses below. Assets and liabilities are reviewed by management at the consolidated level only.
