Segment Reporting [Abstract]  
Segment Information Segment Information
The Company’s products and services are delivered through three reportable segments – Business and Technology Insights, or “Insights”, Conferences and Consulting, as described below.

•Insights equips executives and their teams from every function and across all industries with actionable, objective business and technology insights, guidance and tools. Our experienced experts deliver all this value informed by an unmatched combination of practitioner-sourced and data-driven research to help our clients address their mission critical priorities.

•Conferences provides executives and teams across an organization the opportunity to learn, share and network. From industry-leading conferences to peer-driven communities – each focused on the mission-critical priorities of specific business roles – our offerings enable attendees to experience the best of Gartner insights and guidance.

•Consulting serves senior executives leading technology-driven strategic initiatives leveraging the power of Gartner’s actionable, objective insights. Through custom analysis and on-the-ground support we enable optimized technology investments and stronger performance on our clients’ mission critical priorities.

The Company's Chief Executive Officer is its chief operating decision maker (CODM). The CODM evaluates segment performance and allocates resources based on gross contribution. Gross contribution, as presented in the tables below, is defined as operating income or loss excluding certain Cost of services and product development expenses, Selling, general and administrative expenses, Depreciation, Amortization of intangibles, goodwill impairment and Gain from sale of divested
operation. Certain bonus and fringe benefit costs included in consolidated Cost of services and product development are not allocated to segment expense. The CODM uses gross contribution to allocate resources (including financial resources and employees) for each segment primarily in the Company's annual budgeting process. The CODM then monitors budgeted versus actual results regularly to assess segment operating performance, identify business trends, and modify resource allocations as needed. The accounting policies used by the reportable segments are the same as those used by the Company. There are no intersegment revenues. The Company does not identify or allocate assets, including capital expenditures, by reportable segment. Accordingly, assets are not reported by segment because the information is not available by segment and is not reviewed in the evaluation of segment performance or in making decisions regarding the allocation of resources.

The tables below present information about the Company’s reportable segments for the periods indicated (in thousands).
