Note 8 – Investments in Affiliates

The Short Term Treasury ETF, formerly known as the Invesco Treasury Collateral ETF, is an investment company registered under the Investment Company Act of 1940, as amended, whose shares are primarily purchased and sold on a national securities exchange. In seeking its investment objective, the Invesco Short Term Treasury ETF primarily holds U.S. Treasury Obligations that: (i) are issued in U.S. Dollars; (ii) have a minimum remaining maturity of at least one month and a maximum remaining maturity of 12 months at the time of rebalance; and (iii) have a minimum amount outstanding of $300 million. Because it is advised by the Managing Owner, the Invesco Short Term Treasury ETF is an affiliate of the Fund.

The Invesco Government & Agency Portfolio and the Fund are advised by investment advisers under common control of Invesco Ltd., and therefore the Invesco Government & Agency Portfolio is considered to be affiliated with the Fund.
