IDC Interactive Data Corp.

Interactive Data Corporation (NYSE: IDC), a leading provider of financial market data, analytic tools and related services to financial institutions, active traders and individual investors, today announced that Alan J. Hirschfield, 70, will not seek re-election as a director at the end of his current term, which expires on May 17, 2006. Mr. Hirschfield has served on the Interactive Data Board of Directors since the merger of Data Broadcasting Corporation and Interactive Data in February 2000, and prior to that was co-chairman of the Data Broadcasting Board of Directors since 1992 and was Data Broadcasting's co-chief executive officer from 1992 until November 1999. Interactive Data's Board of Directors plans to elect two new independent directors to replace Mr. Hirschfield and Allan R. Tessler, who announced in January 2006 his intention to retire upon the appointment of a successor. The Board anticipates that these new directors will be elected following the Company's annual meeting of stockholders on May 17, 2006. "It has been very fulfilling for me to serve on the Interactive Data Board during the past six years," stated Alan Hirschfield. "During that time, the Company has nearly doubled in size, fortified its leadership positions in its core markets, entered new market sectors, significantly improved its profitability and created substantial value for shareholders. However, I have decided to not stand for re-election to the Board in order to concentrate on my personal activities and investments. I believe that Interactive Data will benefit from the fresh perspective, experience and expertise that new independent directors will undoubtedly bring." "Alan Hirschfield's contributions have made a profound impact upon Interactive Data, and it is with mixed emotions that we accept his decision to retire," stated John Makinson, chairman of Interactive Data's Board of Directors. "As co-chairman and co-CEO of Data Broadcasting, Alan's leadership was instrumental in guiding the company until the merger with Interactive Data in 2000. Following the merger, he has provided valuable counsel and insight through his active involvement on our Board. We wish Alan continued good fortune in his future endeavors."
