Cognizant (NASDAQ: CTSH), a leading provider of IT services, today announced that it will be added to the S&P 500 Index, effective after the close of trading on Thursday, November 16, 2006.

Widely regarded as the best single gauge of the U.S. equities market, the S&P 500 Index is a world-renowned index comprised of 500 leading companies across the major industries of the U.S. economy. Companies included in the index are selected by the S&P Index Committee, a team of Standard & Poor's economists and index analysts.

"We are honored to join the S&P 500 and to be recognized among the foremost companies in the U.S., many of which we are privileged to count among our customers," said Lakshmi Narayanan, President and CEO of Cognizant.

The S&P 500 is managed to ensure that the index remains a leading indicator of U.S. equities, reflecting the risk and return characteristics of the broader large cap universe on an on-going basis.
