Illinois State Universities Retirement System, Champaign, terminated Global Asset Management due to poor performance, manager turnover and the firms purchase by UBS, said James Hacking, executive director. GAM managed $142 million for the $10 billion pension fund. The GAM assets will be placed in an EAFE index portfolio managed by BGI, which will total more than $1 billion. If trustees decide to conduct a search, it probably will not happen until after the international equity portfolio has been reviewed, which traditionally happens in December, Mr. Hacking said. John Griffith Jr., GAM managing director, declined to comment. Separately, trustees approved a $25 million small-cap to midcap domestic equities allocation to Genesis Capital. The board has not determined the funding source.
