Effective September 3, 2024, the JPMorgan Institutional Tax Free Money Market Fund (the “Fund”) has adopted a non-fundamental policy to ordinarily invest, under normal circumstances, 100% of its total assets in weekly liquid assets (as defined under Rule 2a-7). The maturity restrictions applicable to weekly liquid assets may reduce the Fund’s yield and performance.

Investors should note that the historical yield and performance information for the Fund, as described in its prospectus, is based on the investment policies of the Fund prior to the implementation of this change.
