NOTE 4. BUSINESS SEGMENT INFORMATION We have two business segments — Energy Services Group and Engineering and Construction Group. Dresser Equipment Group is presented as part of discontinued operations through March 31, 2001 as a result of the sale in April 2001 of the remaining businesses within Dresser Equipment Group. See Note 3. Our segments are organized around the products and services provided to our customers. During the fourth quarter of 2000, we announced restructuring plans to combine all engineering, construction, fabrication and project management operations into one company, Halliburton KBR, reporting as our Engineering and Construction Group.
