BMO Ultra Short Tax-Free Fund Class A

Under normal circumstances, the fund invests at least 80% of its assets in municipal securities, the income from which is exempt from federal income tax (including the federal alternative minimum tax (AMT)). It normally maintains an average dollar-weighted effective maturity of one year or less. Effective maturity takes into account the possibility that a bond may have prepayments or may be called by the issuer before its stated maturity date.
