        "supporting_data": "The iShares $ Treasury Bond 1-3yr UCITS ETF is indeed a UCITS fund, which typically presumes a non-complex classification. Its primary investment strategy is 'passively managed' and aims to invest directly in the underlying US Treasury bonds, which suggests a physical replication method (albeit an optimised one). The underlying index (ICE U.S. Treasury 1-3 Year Bond Index) is transparent and consists of straightforward fixed-income securities, supporting ease of understanding of the underlying asset class. However, the Key Investor Information (KII) document explicitly states that 'financial derivative instruments (FDIs) (i.e. investments the prices of which are based on one or more underlying assets) may be used for direct investment purposes'. This indicates that the use of derivatives goes beyond mere efficient portfolio management (EPM), such as currency hedging (also mentioned as using FDIs) or managing inflows/outflows. The use of derivatives for 'direct investment purposes' means they are integral to achieving the fund's investment objective, which, according to MiFID II rules, introduces complexity. Furthermore, the KII explicitly lists 'Counterparty Risk' as a particular risk not adequately captured by the risk indicator, stating it arises from 'the insolvency of any institutions providing services such as safekeeping of assets or acting as counterparty to derivatives or other instruments'. The presence of counterparty risk linked to derivatives, especially when derivatives are used for direct investment, makes the fund's structure, risks, and payoff difficult for retail investors with basic knowledge to understand. While securities lending is also mentioned (which introduces counterparty risk), the critical factor for complexity here is the stated use of derivatives for direct investment, which makes the product's underlying mechanics and risk profile less transparent than a pure physical replication ETF for a retail investor."
