        "supporting_data": "The Invesco Bloomberg Commodity UCITS ETF is classified as complex primarily due to its use of unfunded total return swaps for index replication. The fund does not physically hold the underlying commodities but instead holds a diversified basket of US Treasury Bills, swapping their performance for that of the Bloomberg Commodity Index. This synthetic replication method is explicitly identified as a complex feature under MiFID II rules, as it introduces complexities such as counterparty risk (explicitly mentioned in the KIID under 'Use of Derivatives for Index Tracking Risk') and collateral risk, which are difficult for retail investors to understand. The general MiFID II framework and ESMA guidelines (CESR/09-295, Section 2, paragraph 56 and Section 4, paragraph 91; ESMA35-36-1640, Article 25(4) of MiFID II, point 9) indicate that financial instruments where derivatives are integral to achieving the investment objective, rather than solely for efficient portfolio management, are complex. Furthermore, the explicit rule provided states that 'If any ... Swap usage is identified then the 'classification' must be 'complex'.' The nature of commodity indices, when tracked synthetically, also implies potential complexities like roll costs, contango, or backwardation, which further contribute to the difficulty in understanding the true risk-return profile, even if not explicitly detailed in the KIID."
