Barclays Global Investors (BGI) announced today that Patricia Dunn has decided to resign in her role as non-executive vice chairman at the global asset management firm. She has held this part-time role since stepping down as Global CEO in July 2002 to battle cancer.

“My long tenure with BGI has been transformational, as the firm has grown into the bulwark of investment management success with unusual depth of talent and capability,” said Dunn. “It has been a wonderful privilege to be among those who have been leaders of this organization and to have been part of the intellectual integrity, commitment and innovation of BGI employees.”

“Pattie has made an enormous contribution to the success of BGI, and has been a highly positive influence on so many in the industry,” said Blake Grossman, Global CEO of BGI. “Her dedication to BGI and its commitment to excellence have been a hallmark of her time here and will be missed.”

Dunn held the position of Co-CEO & chairwoman of BGI from 1995 to 1998, when she was named sole CEO & chairwoman of BGI.

Barclays Global Investors is one of the world’s largest asset managers providing structured investment strategies such as risk-controlled active strategies and indexing.
