Ohio School Employees Retirement System, Columbus, extended the deadline for submitting proposals for the $9 billion system's investment consultant RFP to Jan. 3. The original deadline was Dec. 24. Julie Graham-Price, a fund spokeswoman, said the deadline was extended because fund executives need to work on a number of other items on the fund's agenda before the consultant search. The contract with existing consultant Russell Investment Group expires at the end of the first quarter. The firm can rebid. The RFP is available at www.ohsers.org.
