Invesco Global Strategic Income Fund | Invesco Global Strategic Income Fund

1. The following information replaces the seventh paragraph appearing under the heading “Principal Investment Strategies of the Fund” in the prospectuses:

The Fund may invest up to 25% of its total assets in a Cayman Islands exempted company that is wholly-owned and controlled by the Fund (the Subsidiary). The Subsidiary invests in commodity-linked derivatives (including commodity futures, financial futures, options and swap contracts), commodity-linked notes and in Regulation S securities. Regulation S securities are securities of U.S. and non-U.S. issuers that are issued through private offerings without registration with the Securities and Exchange Commission pursuant to Regulation S under the Securities Act. The Subsidiary may also invest in certain fixed-income securities and other investments that may serve as margin or collateral for its derivatives positions. The Fund applies its investment restrictions and compliance policies and procedures, on a look-through basis, to the Subsidiary. Since the Fund may invest a substantial portion of its assets in the Subsidiary, which may hold certain of the investments described in this prospectus, the Fund may be considered to be investing indirectly in those investments through its Subsidiary. Therefore, references in this prospectus to investments by the Fund also may be deemed to include the Fund's indirect investments through the Subsidiary.
