Mark Walker was named chief investment officer of Unilever PLC's U.K. and Ireland pension funds, London, effective Aug. 1, according to spokeswoman Lucila Zambrano.
Mr. Walker will oversee about £5.4 billion ($8.6 billion) in pension assets; he replaces Wendy Mayall, who will be leaving Unilever to work as an investment consultant.
Mr. Walker joined Unilever's global pensions expertise group in September 2010 from Mercer's investment consulting division, where he was principal. While at Mercer, he was instrumental in helping Unilever develop Univest, a cross-border pension pooling platform launched by the company in 2006.
Additional information about whether Mr. Walker will be replaced at Unilever was not available at press time. Ms. Mayall could not be reached for comment.
