The Invesco Investment Grade Defensive ETF (Fund) aims to mirror the performance of the Invesco Investment Grade Defensive Index (Index). This Fund typically allocates at least 80% of its total assets to the securities comprising this Index, which focuses on U.S. investment-grade bonds. The Index prioritizes bonds exhibiting superior quality features, specifically higher credit ratings and shorter maturities. To determine eligibility, each bond receives a quality score, calculated based on its maturity and credit rating. Rather than acquiring every security in the Index, the Fund employs a strategic sampling methodology to achieve its investment objective. Both the Fund and its benchmark Index undergo rebalancing on a monthly basis.
