        "supporting_data": "The AMUNDI US TREASURY BOND 0-1Y UCITS ETF Acc tracks the Bloomberg US Short Treasury Index, which is composed of USD-denominated, short-term US government debt. The ETF uses direct replication, primarily investing in transferable securities representing the index constituents, with a sampled replication model. The document explicitly states that the risk level mainly reflects market risk from investments in short-term international bonds, and that the index is a Total Return Index.  The use of derivatives is limited to managing inflows/outflows and improving index exposition, and securities lending is mentioned for income generation. Crucially, the ETF is a UCITS, which is generally presumed non-complex. The index itself is straightforward, and there are no indications of embedded derivatives, leverage, or other complex structures that would challenge the baseline UCITS presumption. The presence of 'market risk' and 'tracking error' are standard for ETFs and do not inherently make an instrument complex under MiFID II. The ETF's objective, structure, and risks are easily understood by a retail investor with basic knowledge."
