        "supporting_data": "This iShares Bloomberg Enhanced Roll Yield USD ETF is classified as complex primarily due to its use of derivatives.  The KID explicitly states that the fund invests in 'unfunded total return swaps' to achieve its objective of tracking the Bloomberg Enhanced Roll Yield Total Return Index.  This index itself is complex, incorporating commodity futures contracts and aiming to mitigate the effects of negative roll yield.  The use of swaps introduces counterparty risk and the complexity of the index makes understanding the fund's overall risk-return profile challenging for retail investors with basic knowledge.  Even though the fund is UCITS compliant, the central role of derivatives in its investment strategy and the inherent complexities of the underlying index override the general UCITS presumption of non-complexity.  The ESMA guidelines clearly indicate that derivatives are generally complex and this is particularly true when they are integral to the investment strategy rather than simply employed for efficient portfolio management."
