In conjunction with the acquisition of SiriusDecisions in the first quarter of 2019, the Company realigned its management structure into Products, Research and SiriusDecisions.

The Products segment includes the revenues of the Connect, Analytics, and Events products (excluding the revenues from SiriusDecisions products) and the costs of the organizations responsible for developing and delivering these products. In addition, this segment includes Consulting revenues and the related cost of the Company’s project consulting organization. The project consulting organization delivers a majority of the Company’s project consulting revenue (excluding SiriusDecisions consulting) and certain advisory services primarily related to the Analytics product line. This segment also includes the costs of the product management organization that is responsible for product pricing and packaging and the launch of new products.

The Research segment includes the revenues of the Research products and the cost of the organizations responsible for developing and delivering the Research products (excluding the costs and revenues from SiriusDecisions products). In addition, this segment includes Consulting revenues primarily from the delivery of advisory services (such as workshops, speeches and advisory days) delivered by the Company’s research analysts.

The SiriusDecisions segment includes the revenues of the legacy SiriusDecisions products and the costs of the organizations responsible for developing and delivering these products. In addition, this segment includes the costs of marketing, technology development and business support departments of the legacy SiriusDecisions business.

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, except as noted above for the SiriusDecisions segment, 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, interest and other expense, and losses on investments. The accounting policies used by the segments are the same as those used in the consolidated financial statements.

The Company is providing disaggregated revenue by product in the segment tables below (in thousands). The 2018 amounts have been reclassified to conform to the current presentation.
