        "classification": "complex",
        "supporting_data": "The Fund is a UCITS ETF, which initially presumes it to be non-complex. However, this presumption is overturned by several features. The Fund explicitly states it 'invests in financial derivative instruments ('FDIs') with UBS AG, London Branch ('UBS') as counterparty. Under the terms of the FDIs, the performance of the Index is swapped from UBS to the Fund... consequently, the Fund's performance reflects the performance of the Index'. This confirms the use of synthetic replication, which relies on derivatives (swaps) as an integral part of its investment objective, not merely for efficient portfolio management (EPM). This aligns with the 'Complex' classification under Rule 2 ('Evaluate the Use of Derivatives') and Rule 3 ('Analyze the Replication Method') of the provided MiFID II Complexity Assessment Rules. Furthermore, the Key Investor Information Document explicitly highlights 'Counterparty risk' as a material risk, stating 'The failure of UBS to perform under the terms of the FDIs could significantly affect the Fund.' This direct reference to a risk arising from the derivative-based structure makes the ETF's risks and payoff difficult for retail investors with basic knowledge to understand, supporting the 'Complex' classification under Rule 4 ('Assess Ease of Understanding'). The ESMA MiFID II Supervisory Briefing (ESMA35-36-1640) implicitly supports the view that not all UCITS are automatically non-complex, especially if they are 'structured UCITS' or have features that make them difficult to understand for retail investors, even if the 2009 CESR document had a broader statement. The instruction 'If any element of ... any Swap usage is identified then the 'classification' must be 'complex'' is also directly met."
