Effective Date
Standard & Poor’s is discontinuing its relationship with Barra and creating a new partnership with Citigroup. As a result, the December 2005 S&P/Barra contract which expires on December 16, 2005 will be the last listing to bear the S&P/Barra name. Effective with the listing of the March 2006 contract on Monday, September 19, 2005, and following the expiration of the September contract on Friday, September 16, 2005, the 2006 CME contracts will be identified as S&P/Citigroup Growth Index Futures or S&P/Citigroup Value Index Futures. All CME Growth and Value contracts listed in 2005 (December ’05 contracts) will retain the S&P/Barra naming and methodology.
