The Illinois Municipal Retirement Fund was created in 1939 by the Illinois General Assembly and began operating in 1941 with 5 original employers and $5,000 in assets. Today IMRF serves almost 3,000 employers and has approximately $41 billion in assets.
Since 1941, IMRF has provided employees of local governments and school districts in Illinois (with the exception of the City of Chicago and Cook County) with a sound and efficient system for the payment of retirement, disability, and death benefits.
