The Invesco Floating Rate Municipal Income ETF (PVI) aims to replicate the performance of the ICE US Municipal AMT-Free VRDO Constrained Index. This Fund typically allocates a minimum of 80% of its total assets to U.S. dollar-denominated, tax-exempt variable rate demand obligations (VRDOs). The benchmark Index itself monitors tax-free VRDOs publicly issued by U.S. states, territories, and their various political subdivisions, all of which feature interest rates that are adjusted daily, weekly, or monthly.
