AAAmf Rated by Fitch 7-21

The Illinois Funds, which is managed in a manner generally consistent with SEC regulated Rule 2a-7 money market funds, has earned Fitch’s highest rating (AAAmmf). The rating is based on Fitch’s analysis of the pool’s credit quality, maturity, diversification, and management.  The rating demonstrates that the fund has an extremely strong capacity to maintain principal stability and limit exposure to losses due to interest rate and/or credit risk. The Illinois Funds has continuously received the highest prime investment grade for a government money market fund since 1996.
