Note 12 - Operating Segment and Enterprise Wide Reporting The Product segment includes the costs of the product management organization that is responsible for pricing and packaging and the launch of new products. In addition, this segment includes the costs of the Companys Analytics, Connect and Events organizations. Revenue in this segment includes all of the Companys revenue (including Research and Connect) except for revenue from advisory services and project consulting services that are delivered by personnel in the Research and Project Consulting segments. The Research segment includes the costs of the Companys research personnel who are responsible for writing the research and performing the webinars and inquiries for its Research and Connect products. In addition, the research personnel deliver advisory services (such as workshops, speeches and advisory days) and a portion of the project consulting services. Revenue in this segment includes only revenue from advisory services and project consulting services that are delivered by the research personnel in this segment. The Project Consulting segment includes the costs of the consultants that deliver the majority of the Companys project consulting services. Revenue in this segment includes the project consulting revenue delivered by the consultants in this segment. The Company evaluates reportable segment performance and allocates resources based on segment revenues and expenses. Segment expenses include the direct expenses of each segment organization and exclude selling and marketing expenses, general and administrative expenses, stock-based compensation expense, depreciation expense, adjustments to incentive bonus compensation from target amounts, amortization of intangible assets, other income and gains (losses) on investments. The accounting policies used by the segments are the same as those used in the consolidated financial statements. The Company does not identify or allocate assets, including capital expenditures, by operating segment. Accordingly, assets are not being reported by segment because the information is not available by segment and is not reviewed in the evaluation of performance or making decisions in the allocation of resources. In 2018, as part of the adoption of ASC 606, the Company updated its segment disclosures to present disaggregated revenue by product line within all of its reportable segments. The Company did not make any changes to the number or type of reporting segments themselves. Accordingly, the 2017 and 2016 amounts have been reclassified to conform to the current presentation.
