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.

?We welcome Rona to the Interactive Data Board,? stated John Makinson, chairman of the Company's Board of Directors. ?Since becoming chief executive of the FT Group, she has naturally spent considerable time learning more about Interactive Data's business. I am confident that Rona's insights and counsel will be very valuable in helping Interactive Data develop, refine and implement the strategies necessary to achieve its business and financial objectives.?

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.
