Bedford, Mass., September 21, 2007 - Interactive Data Corporation (NYSE: IDC), a leading provider of financial market data, analytics and related services to financial institutions, active traders and individual investors, today announced that Rona Fairhead was appointed to chairman of the Company's Board of Directors, effective immediately.  Fairhead succeeds John Makinson, who has resigned from serving on Interactive Data's Board of Directors. 

Fairhead has served as one of five Pearson-affiliated directors on the Interactive Data Board of Directors since February 2007.  She will also serve as chair of the Nominating and Corporate Governance Committee.  Phil Hoffman, a director on the Interactive Data Board since February 2007, will replace Makinson as chair of the Compensation Committee.  Makinson had been chairman of the Interactive Data Board since December 2002 and served as a member of the Company's Board from February 2000 to October 2000. 

John Makinson stated, "It was an honor to serve as chairman on Interactive Data's Board for nearly five years.  During that time, Interactive Data established itself as a trusted industry leader while creating significant value for customers, employees, business partners and shareholders in the process.  Although I will miss working with Stuart and rest of his management team, Rona possesses the leadership skills and overall business and financial acumen to help guide the Company into its next phase of growth."

Fairhead, 45, is currently chief executive officer of the Financial Times Group where she is responsible for overseeing the Financial Times, Pearson's international business newspapers and financial magazines, as well as its interests in Interactive Data, FTSE, which is owned jointly with the London Stock Exchange, and The Economist Group.  Fairhead joined Pearson in October 2001 as deputy finance director, became chief financial officer in June 2002 and was appointed chief executive of the Financial Times Group in June 2006.  She serves on the Pearson board and is also a member of the Pearson management committee.  She was appointed a non-executive director of HSBC Holdings plc in 2004.

"On behalf of the whole Board, I'd like to thank John for his service and significant contribution to Interactive Data's success.  It is a privilege for me to follow in his footsteps," said Rona Fairhead.  "The people of Interactive Data have always sought to provide their customers with robust, innovative solutions combined with excellent service. This approach has established the Company as a widely respected industry leader and has produced notable growth over the last several years. I look forward to helping the Company continue that success and become an ever-stronger force in the industry."

Before joining Pearson, Fairhead was executive vice president, strategy and group financial control and a member of the Executive Board at ICI plc, the international specialty chemicals and paints company.  Prior to her six years at ICI, she was a senior executive in the aerospace industry, working for Bombardier/Shorts Aerospace and British Aerospace. In her early career she worked for Bain & Co and Morgan Stanley. Fairhead has a law degree from Cambridge University and an MBA from Harvard Business School.
