Previously, Mr. Fradin spent more than seven years in various executive positions with Automatic Data Processing (ADP), including president of its global employer services group, where he doubled revenues to $4.5 billion, improved profit margins resulting in operating income of over $1.3 billion and pioneered the company's entry into total human resources outsourcing for small businesses. Mr. Fradin also spent 18 years at global management consulting firm McKinsey and Company Inc., where he counseled Fortune 500 companies on their business strategies, with a particular emphasis on innovation and building market value.

"We are extremely pleased that Russ has accepted the opportunity to join Hewitt Associates as chairman and CEO," said Cheryl A. Francis, Hewitt's lead director. "He is a proven leader with a unique blend of experience and skills that are a perfect complement to Hewitt's core businesses. Furthermore, his passion for our industry and reputation for tackling tough issues and achieving results will serve Hewitt's clients, associates and stockholders very well."

Mr. Fradin holds a bachelor's degree in economics from the University of Pennsylvania and a master's in business administration from Harvard Business School. He currently serves on the board of directors of the Corporate Executive Board.

"I am very excited to join this organization," said Mr. Fradin. "Hewitt is a well-established name and a highly regarded industry leader that excels at serving an impressive group of clients. I am energized by the opportunity to build on this foundation to create more value and, ultimately, to position Hewitt for long-term profitable growth and a stronger future for clients, associates and stockholders."

Mr. Gifford, who has been with Hewitt for more than 30 years and CEO since 1992, will remain with the organization through the end of its fiscal year (September 30, 2006) to help ensure a smooth transition.

"I feel very privileged to have served Hewitt and our clients for more than 30 years, and have a great sense of pride in this organization and our 22,000 associates worldwide," said Mr. Gifford. "Now is the appropriate time to hand the reins over to a new leader and I have every confidence that Russ will effectively lead Hewitt through the next stage of its development."
