Boston Retirement System is searching for a custodian.
The $6.3 billion pension fund issued an RFP to meet regulatory requirements as well as for due diligence, said John Kelly, investment analyst.
Current custodian State Street Bank is eligible to rebid, he said.
The RFP is available on the website of investment consultant NEPC, which is assisting with the search. Proposals are due at 5 p.m. EDT on Oct. 18. The pension fund hopes to make a selection in three to six months, Kelly said.
