Williams recently retired from Wellington Management Co. LLP where she had served as a senior vice president and partner since 1995. In her 26 years in the investment management business, Williams established strong credentials as a financial analyst with more than 20 years experience covering industries including paper and forest products, publishing, metal and mining, and home improvement. During her career, Institutional Investor Magazine repeatedly recognized Williams as a "Best of the Buy Side" analyst.

While at Wellington, Williams was directly responsible for managing $1 billion in client assets, which included investments in Weyerhaeuser.

"We are extremely fortunate to have someone of Kim's stature join our board," said Steven R. Rogel, chairman, president and chief executive officer. "As our board works with our management team to chart our strategic direction, we will benefit from Kim's investment experience and understanding of industrial companies."

Williams began her career as an investment analyst with the Imperial Chemical Industries Pension Fund in London, England in 1979. She also worked at Loomis, Sayles and Co., Inc. in Boston before joining Wellington in 1986. Williams holds a masters in economics from the University of London.
