The Fund is not a money market fund and does not attempt to maintain a stable net asset value (NAV). The Fund does not purchase all of the securities in the Index; instead, the Fund utilizes a "sampling" methodology to seek to achieve its investment objective. The Fund and the Index are rebalanced and reconstituted monthly.Effective after the close of markets on Aug. 25, 2023, the Fund’s name and ticker changed from Invesco Treasury Collateral ETF (ticker: CLTL) to Invesco Short Term Treasury ETF (ticker: TBLL).
