Segment Information ASC Topic 280, Segment Reporting ("ASC 280"), establishes standards for reporting information about segments and requires that a public business enterprise reports financial and descriptive information about its segments. Segments are components of an enterprise for which separate financial information is available and are evaluated regularly by the chief operating decision maker ("CODM") in deciding how to allocate resources and in assessing performance. Our chief executive officer is identified as the CODM as defined by ASC 280. To align with the internal management of our business operations based on service offerings, our business is organized into two segments. Refer to Note 14 Revenues for a description of our Software Solutions and Data and Analytics segments. Separate discrete financial information is available for these two segments and the operating results of each segment are regularly evaluated by the CODM in order to assess performance and allocate resources. We use EBITDA as the primary profitability measure for making decisions regarding ongoing operations. EBITDA is earnings before Interest expense, net, Income tax expense (benefit) and Depreciation and amortization. We do not allocate Interest expense, Other expense, net, Income tax expense (benefit), equity-based compensation and certain other items, such as purchase accounting adjustments and acquisition-related costs to the segments, since these items are not considered in evaluating the segments' overall operating performance. On January 1, 2018, we realigned the composition of our two reportable segments. Certain enterprise business intelligence offerings in our Data and Analytics segment were moved to our Software Solutions segment. This change aligns with our go-to-market strategy and with the internal management of our business operations, including the allocation of resources and assessment of performance. Prior period results have been reclassified to conform to the current segment presentation.
