        "supporting_data": "This UCITS ETF is classified as 'complex' primarily due to the specific nature and methodology of its benchmark index, the 'MSCI ACWI IMI Water ESG Filtered Net Total Return Index'. While the ETF benefits from the general UCITS presumption of non-complexity and employs physical replication, the 'ESG Filtered' and 'best-in-class approach' elements of the index introduce a significant layer of complexity. The Key Investor Information Document (KID) explicitly highlights 'risks related to ESG methodologies and calculation of ESG scores'. This indicates that understanding the index's nuanced composition, the criteria for company inclusion/exclusion, and the potential impact of ESG controversies requires a level of knowledge beyond that of an average retail investor. This aligns with the provided MiFID II complexity rules, which state that if the 'index itself is complex or opaque' (Rule 5, Nuance), this can make the ETF complex, overriding the general UCITS presumption. No significant use of leverage, derivatives integral to the strategy, or swaps for replication is indicated in the current policy. The ETF also does not mention inverse exposure, contingent convertible bonds, roll costs, contango, or backwardation effects."
