The Invesco Preferred ETF (Fund) is based on the ICE BofAML Core Plus Fixed Rate Preferred Securities Index (Index). The Fund will normally invest at least 80% of its total assets in fixed rate US dollar-denominated preferred securities that comprise the Index. The Index tracks the performance of fixed rate US dollar-denominated preferred securities issued in the US domestic market. (Securities must be rated at least B3, based on an average of three leading ratings agencies: Moody’s, S&P and Fitch) and must have an investment-grade country risk profile (based on an average of Moody’s, S&P and Fitch foreign currency long-term sovereign debt ratings). 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 on a monthly basis.Read More
