It is passively managed and aims to track the MSCI World Climate Paris Aligned Filtered Index, an equity index, which itself appears transparent based on the provided information (MSCI.com reference). The Key Investor Information document does not explicitly state the use of derivatives for its core replication strategy (i.e., synthetic replication via total return swaps), leading to an inference of physical replication. The ETF does not indicate significant leverage or capital protection features that would inherently make it complex. However, the document explicitly lists 'Counterparty risk' as an 'important risk materially relevant to the Sub-Fund which are not adequately captured by the indicator'. While counterparty risk can arise from various activities (e.g., securities lending), it can also stem from the use of derivatives for efficient portfolio management (EPM), such as currency swaps for hedging. The specific instruction provided states: 'If any element of ... any Swap usage is identified then the classification must be complex.' Given that 'Counterparty risk' is highlighted as a material risk, it implies potential exposure to OTC derivative instruments (such as currency swaps) for risk management, thereby identifying a potential 'swap usage'. This interpretation, in line with the strict rule provided, overrides the initial UCITS presumption and leads to a complex classification. Although these derivatives (if present) are for risk management (EPM) rather than the inherent investment strategy, the explicit inclusion of counterparty risk as a material concern, combined with the stringent rule regarding swap usage, results in a 'complex' classification.'}```**Classification: Complex**",
