    "classification": "complex",
    "supporting_data": "The KIID and factsheet indicate that while the ETF primarily uses physical replication, it may employ derivatives (including OTC derivatives) when direct investment is impracticable or to generate efficiencies. The presence of counterparty risk from OTC derivatives and the potential use of derivatives beyond simple replication suggest complexity under MiFID II. The risk category of 6 and the mention of derivative-related risks further support this classification.",
    "confidence": 85,
    "risk_level": 6,
    "counter_argument": "The ETF is UCITS-compliant and primarily uses physical replication, which typically suggests non-complex status. However, the use of OTC derivatives and the associated counterparty risk, even if collateralized, introduces elements that may not be easily understood by retail investors, thus warranting a 'complex' classification.",
    "additional_notes": "The PRIIPs KID was not provided, but the KIID and factsheet sufficiently indicate the use of derivatives and the associated risks. The factsheet confirms the physical replication method but also acknowledges the potential use of derivatives, reinforcing the complexity assessment."
