        "supporting_data": "The Invesco Morningstar US Energy Infrastructure MLP UCITS ETF is classified as 'complex' despite being a UCITS fund. While UCITS ETFs are generally presumed non-complex, this presumption is overturned when specific features make their structure, risks, or payoff difficult for retail investors to understand. The primary factor driving this 'complex' classification is the ETF's use of unfunded total return swaps to achieve its investment objective. The provided rules explicitly state that if 'any Swap usage is identified then the 'classification' must be 'complex''. The KID clearly states: 'To achieve the objective the Fund will use unfunded swaps (u201cSwapsu201d).' This indicates that derivatives are integral to achieving the fund's investment objective, rather than solely for efficient portfolio management, which is a key criterion for complexity under Rule 2 ('Evaluate the Use of Derivatives').Furthermore, the replication method is synthetic. The fund 'will purchase securities that are not contained in the Index' and 'The performance of the Index is swapped from the counterparty to the Fund in exchange for the performance of equities and equity related securities held by the Fund'. This synthetic replication introduces opacity and risks such as 'counterparty risk' and 'collateral risk' (as noted by the 'Synthetic ETF Risk' in the KID, referring to 'insolvency of any institutions providing services such as safekeeping of assets or acting as counterparty to derivatives or other instruments, may expose the Fund to financial loss'). These concepts are generally considered difficult for retail investors with basic knowledge to understand, aligning with Rule 4 ('Assess Ease of Understanding').While the fund is not explicitly leveraged, uses no inverse strategy, and the high-risk rating (7/7) relates to market volatility, the core structure involving swaps for synthetic replication is the definitive factor for complexity. The underlying Morningstar MLP Composite Index, tracking U.S. publicly traded energy master limited partnerships (MLPs), may also add a layer of complexity for retail investors due to the specific nature and structure of MLPs, although the swap usage is the dominant complexity driver. No mention of contingent convertible bonds was identified."
