Name change following acquisition by Interactive Data Corporation

FRANKFURT, Germany – July 13, 2006 – IS.Teledata AG today announced that the company has formally changed its name to Interactive Data Managed Solutions AG. The provider and operator of customised financial market information systems has made this change following its acquisition in December 2005 by Interactive Data Corporation (NYSE: IDC), a leading global provider of financial market data, analytics and related services to financial institutions, active traders and individual investors.

The subsidiaries of Interactive Data Managed Solutions AG in France, Italy, UK, Italy, Spain, Finland and Switzerland will also change their names.

The name change will enable Interactive Data Managed Solutions to leverage the strength of Interactive Data’s brand around the world. Interactive Data Managed Solutions is now managed as part of the ComStock group within Interactive Data Corporation.
