Business Segments Effective July 1, 2020, we began managing our business under a new organizational structure on a regional basis through our three geographic markets, North America, EMEA and Emerging Markets. These became our reportable segments in the third quarter of 2020. Prior to this change, our reportable segments consisted of two global practices, Workforce Excellence and Business Transformation Services, which focused on providing similar and/or complementary products and services across our diverse customer base within target markets. The reorganization was done to achieve the following:  Unlock the potential of organic growth to achieve better business results for our clients and the Company.  Simplify the matrix and empower rapid local decision making in service of our clients.  Leverage global practice systems, processes, and intellectual property while enabling regional authority to better align and deliver to local client needs.  Enable efficient use of our corporate infrastructure with regional resources. Across our regional operating structure, the Company provides Workforce Transformation Services categorized into three primary solution sets:  Organizational Performance Solutions ("OPS") - focus is on managed learning services, digital learning strategies and content development, business consulting, and leadership development solutions  Technical Performance Solutions ("TPS") - focus is on engineering and technical services, enterprise technology adoption and Human Capital Management ("HCM") implementation services.  Automotive Performance Solutions ("APS") - provides sales enablement solutions, including custom product sales training and other customer loyalty and marketing related services. We have also identified four focus industries to deliver these services which include Automotive, Financial Services, Defense and Aerospace and Technology. We do not allocate the following items to the segments: general &amp; administrative expenses, sales &amp; marketing expenses, restructuring charges, gain on change in fair value of contingent consideration, gain on sale of business, interest expense, other income (expense), and income tax expense (benefit).
