The Invesco Morningstar US Energy Infrastructure MLP UCITS ETF (Acc) aims to mirror the total return performance of the Morningstar MLP Composite Index (referred to as the "Reference Index"), after accounting for associated fees. The Reference Index itself is designed to offer broad and diversified exposure to US-based, publicly traded Master Limited Partnerships (MLPs) within the energy infrastructure sector. Its constituents are weighted based on the monetary value of their annual distributions, with an individual cap of 10%.
