Public School Retirement System of Missouri, Jefferson City, will issue RFIs March 29 for an enhanced index manager to run about $1 billion and an all-cap domestic manager for $500 million, said Craig Husting, CIO for the $20 billion fund. The enhanced managers index will be the S&P 500 with 50 to 100 basis points of outperformance, he said. The all-cap managers benchmark will be the Russell 3000. Finalists will be selected on or before May 7. The board is scheduled to make its decision June 7. The system also has received responses for a $750 million active core international mandate, he said. Three or four finalists will be selected by March 19. Managers will make their presentations to the board April 13, when it will decide. Funding for all new hires will come from existing managers.
