Teradata Named to Elite Dow Jones Sustainability Indexes

Teradata Corporation (NYSE: TDC) announced today that its environmental, social and economic performance earned it a place on the elite 2010 Dow Jones Sustainability North America and World Indexes.

The Dow Jones Sustainability World Index comprises more than 300 companies identified as the top 10 percent of the leading sustainability performers among the largest 2,500 companies in the Dow Jones Global Total Stock Market Index. Companies on the North America Index represent the top 20 percent of the highest performers.

“Being recognized in this rigorous external benchmark further reinforces our commitment to continue to be a sustainability leader. Making sustainability practices a part of the corporate operating philosophy continues to make good business sense,” said Bruce Langos, Chief Operations Officer, Teradata Corporation.

Launched in 1999, the Dow Jones Sustainability Indexes are the first global indexes that track the financial performance of the leading sustainability-driven companies worldwide. When selecting the top performers in each business sector, Dow Jones reviews companies on several general and industry-specific topics related to economic, environmental and social dimensions. These include corporate governance, environmental policy, climate strategy, human capital development and labor practices. The indexes are compiled annually by Dow Jones and the Zurich-based Sustainable Asset Management Group. More information is available at www.sustainability-indexes.com.
