SUBJECT:	Open Interest Reporting Error

Due to a firm’s reporting error, the Preliminary Open Interest distributed on June 2, 2005, overstated the amount of open interest in the Eurex US June 2005 10-Year Treasury Note contract. The Final Volume and Open Interest report distributed today reflects the correct Volume and Open Interest for the business date June 1, 2005.
