    ],
    "classification": "complex",
    "supporting_data": "The ETF uses FLEX Options, which are customized derivative instruments, to achieve its investment objectives. The structure involves a buffer and cap mechanism that requires understanding of complex derivative strategies and their reset periods. The Target Outcome Period and the conditional returns based on the S&P 500 Index performance introduce additional layers of complexity that may not be easily understood by retail investors. The use of derivatives is not merely for efficient portfolio management but is central to the fund's strategy, making it inherently complex under MiFID II.",
    "confidence": 90,
    "risk_level": 4,
    "counter_argument": "The ETF is UCITS-compliant and has a clear risk profile (SRRI 4), which might suggest it is non-complex. However, the reliance on FLEX Options and the conditional return structure override this, as these features require specialized knowledge to fully comprehend the risks and potential outcomes.",
    "additional_notes": "The PRIIPs KID and factsheet reinforce the complexity by detailing the derivative-based strategy and the conditional nature of returns. The 'comprehension warning' in PRIIPs documents, if present, would further support the 'complex' classification."
