        "supporting_data": "The iShares STOXX Europe 50 UCITS ETF aims to achieve a return that reflects the STOXX Europe 50 Index by investing in the equity securities that make up the Index, employing a physical replication strategy. The KIID states that the fund is passively managed and aims to invest in the equity securities of the index. The document does not mention any use of derivatives for its investment objective, efficient portfolio management, or any other purpose. It also mentions that the fund may engage in short-term secured lending of its investments to generate additional income, which is a common practice and not indicative of complexity. The underlying index (STOXX Europe 50) is a standard market capitalization-weighted index of 50 European companies, which is considered transparent and understandable. The risk and reward profile is rated six, but this is due to market risk and volatility, not structural complexity. The assessment aligns with MiFID II's presumption that UCITS ETFs using physical replication of transparent indices are non-complex, as their structure, risks, and payoff are generally understandable to retail investors. There are no features present that would necessitate a complex classification based on the provided rules, such as embedded derivatives, synthetic replication, or complex underlying assets."
