    "supporting_data": "The SPDR Bloomberg U.S. Aggregate Bond UCITS ETF is classified as non-complex under MiFID II. While it uses derivatives for efficient portfolio management (EPM), there is no evidence of synthetic replication, leverage, or inverse strategies. The fund primarily uses physical replication with stratified sampling. The Bloomberg U.S. Aggregate Bond Index, while broad, is a well-established benchmark with transparent constituents. The fund's risk profile (category 4) is medium and aligns with its investment in investment-grade bonds. The KIID and fact sheet confirm UCITS compliance and a straightforward investment strategy. The only potential complexity factors are the index's diversity and credit risk from mortgage-backed securities, but these do not trigger a 'complex' classification under MiFID II.",
