While it is a UCITS fund, which typically presumes non-complexity, this presumption is overturned due to its specific structural features and the explicit rules provided. The fund's investment policy states that it uses 'unfunded swaps ('Swaps')' to achieve its objective of replicating the KBW NASDAQ Financial Technology Index. This constitutes synthetic replication, where derivatives are integral to the investment strategy rather than solely for efficient portfolio management (EPM). The use of swaps introduces risks such as counterparty risk and collateral risk (even if the fund holds a basket of equities, the performance exchange introduces specific counterparty exposure), which are considered difficult for retail investors with basic financial knowledge to understand. The Key Investor Information document itself highlights 'Synthetic ETF Risk', specifically noting that the fund 'will enter into swap agreements to exchange the performance of those securities for the performance of the reference index', reinforcing the structural complexity. According to MiFID II rules, if derivatives are integral to achieving the investment objective (Rule 2) or if synthetic replication is used (Rule 3), the ETF is generally classified as complex. Furthermore, the ESMA guidelines (ESMA35-36-1640, page 9, footnote 12) clarify that 'structured UCITS' are explicitly excluded from the automatically non-complex category. A UCITS ETF employing synthetic replication via swaps for its primary objective falls under the category of a 'structured' UCITS in terms of its operational mechanism and risk profile, making it complex. The instruction also explicitly states that if any swap usage is identified, the classification must be 'complex'.'}```",
