BUSINESS AND GEOGRAPHIC AREAS

Dow conducts its worldwide operations through global businesses, and the Corporation's business activities comprise components of Dow's global businesses rather than stand-alone operations. The Corporation sells its products to Dow in order to simplify the customer interface process at market-based prices in accordance with Dow's long-standing intercompany pricing policy. Because there are no separable 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 areas based on customer location; long-lived assets are attributed to geographic areas based on asset location. Sales to external customers and long-lived assets by geographic area were as follows:
