        "supporting_data": "The Vanguard S&P 500 UCITS ETF employs passive management (indexing) through physical replication of the Standard & Poor's 500 Index.  While the fund mentions using derivatives to reduce risk or cost, and for generating extra income or growth, the details provided do not suggest that derivatives are integral to the index tracking strategy.  The key aspect is the physical replication of securities, which is inherently transparent, making the fund easy to understand for retail investors with basic knowledge.  While the prospectus mentions secured lending and potential variations in daily stock market movements, other influential factors, and the risk category of 6, these do not significantly alter the non-complex classification due to the straightforward index tracking method. Roll costs, contango or backwardation effects are not mentioned, suggesting a straightforward structure.   No mention of Contingent Convertible Bonds, leverage, or other complex structures were noted in the supplied KIDs.   The assessment focuses on the transparency and straightforwardness of the ETF's replication method, as well as clarity around the risks and features which supports the non-complex classification.  The index being a well-known, straightforward S&P 500 index further reinforces this."
