Business and Geographic Regions

BUSINESS AND GEOGRAPHIC REGIONS

TDCC conducts its worldwide operations through principal product groups, and the Corporation's business activities comprise components of TDCC's principal product groups rather than stand-alone operations. The Corporation sells substantially all of its products to TDCC in order to simplify the customer interface process, at prices determined in accordance with the terms of an agreement between UCC and TDCC. Because there are no separate reportable business segments for the Corporation and no detailed business information is provided to a chief operating decision maker regarding the Corporation's stand-alone operations, the Corporation's results are reported as a single operating segment.

Sales are attributed to geographic regions based on customer location; long-lived assets are attributed to geographic regions based on asset location. Sales to external customers and long-lived assets by geographic region were as follows:
