        "supporting_data": "The Vanguard S&P 500 UCITS ETF employs passive management (indexing) via physical replication of the Standard & Poor's 500 Index. This method of replication is considered transparent and straightforward.  While the ETF may use derivatives for risk management or cost reduction, the description in the KID highlights that these derivatives are for efficient portfolio management, not integral to achieving the investment objective. This aligns with the MiFID II presumption of non-complexity for UCITS ETFs. The use of securities lending, although introducing counterparty risk, is a secondary feature and managed within UCITS guidelines.  The index being tracked (S&P 500) is also well-documented and generally considered transparent. Based on the provided data, the key characteristics point towards a non-complex classification, as it does not incorporate any of the factors that would automatically trigger a complex classification (e.g. synthetic replication, embedded derivatives, significant leverage, or opaque index).  The mention of temporary lending is not a concern; this aligns with accepted UCITS lending practices.  The fact that the ETF is a UCITS ETF, a strongly regulated financial instrument, also contributes to the non-complex determination."
