Item 1.01 Entry Into a Material Definitive Agreement.

Amendment to Participant Agreement

On September 30, 2020, Invesco Capital Management LLC (the “Managing Owner”), Invesco DB US Dollar Index Trust, on behalf of Invesco DB US Dollar Index Bullish Fund and Invesco DB US Dollar Index Bearish Fund (each, a “Fund” and together, the “Funds”), and each of the other Invesco DB exchange-traded commodity pools executed an amendment to the Participant Agreements currently in place with each financial institution eligible to conduct creation and redemption transactions directly with the Funds (“Authorized Participant”). The purpose of the Amendment is to revise Attachment A to the Participant Agreement to change the number of common units of beneficial interest (“Shares”) that currently comprise the large blocks of Shares issued or redeemed by a Fund to an Authorized Participant (“Creation Units”) from 200,000 Shares to 100,000 Shares, or such other size as the Managing Owner may determine in the future, with such change effective as of market open on November 2, 2020.

The Participant Agreement governs the relationship between the Funds and an Authorized Participant and sets forth the procedures for the creation and redemption of Creation Units and for the delivery of cash required for such creations or redemptions. The Managing Owner may delegate its duties and obligations under a Participant Agreement to Invesco Distributors, Inc. or The Bank of New York Mellon (the administrator and transfer agent to the Funds) without consent from any Authorized Participant. The Participant Agreement may be amended by the Managing Owner only with the consent of an Authorized Participant, while the procedures attached thereto, including Attachment A, may be amended with notice to an Authorized Participant. Shareholder consent is not required in either case.
