Offering Realignment between Segments In 2019, IBM updated its reportable segments and in 2020, this segment structure remains consistent. During the first quarter of 2020, the company realigned offerings and the related management system to reflect divestitures completed in the second half of 2019 and tighter integration of certain industry-related consulting services. Accordingly, IBM is updating its Cloud & Cognitive Software segment, Global Business Services segment and the Other – divested businesses category in the first quarter of 2020 and recasting historical information in these areas for consistency with the go-forward performance. To provide some context of the magnitude of these changes, total recast revenue in 2019 is approximately $0.3 billion of IBM’s total $77 billion. There is no change to the Global Technology Services, Systems, or Global Financing segments, and there is no impact to IBM’s consolidated results. Management System Change Resulting Segment Implications - Cloud & Cognitive Software (Cognitive Applications) Divestitures of IBM's risk analytics and regulatory offerings and sales performance management offerings + Other - divested businesses - Cloud & Cognitive Software (Cognitive Applications) Realignment of certain industry-related consulting offerings to the Global Business Services segment + Global Business Services (Consulting) These changes are effective in the first quarter of 2020. Subsequent to the first quarter, on April 6, 2020, Arvind Krishna became Chief Executive Officer of IBM and announced a number of management changes, which did not impact the company’s reportable segments.
