However, the Key Investor Information Document (KID) explicitly states that 'financial derivative instruments (FDIs) may be used for direct investment purposes' as part of the Fund's optimising techniques. This phrasing suggests that derivatives are not solely for efficient portfolio management (EPM) but are integral to achieving the investment objective. The KID also lists 'Counterparty Risk' as a 'Particular risk not adequately captured by the risk indicator', directly attributing it to the use of derivatives and other instruments. Understanding the implications of derivatives used for 'direct investment purposes' and the associated counterparty risk typically requires knowledge beyond that of a retail investor with basic financial literacy. Furthermore, the underlying 'Bloomberg Barclays MSCI US Corporate High Yield Sustainable BB+ SRI Bond Index' itself introduces significant complexity. It comprises 'sub-investment grade' (high-yield) bonds, which inherently carry higher credit risk and sensitivity to interest rate changes. The index applies extensive and nuanced ESG/SRI screening criteria, including numerous industry exclusions (e.g., alcohol, tobacco, gambling) and requires companies to meet specific MSCI ESG scores/controversies, adopting a 'best-in-class approach' that results in a portfolio 'reduced by at least 20% compared to the Parent Index'. While this methodology is transparent, its intricate construction and the specific impact of these screens on the portfolio's risk-return profile and diversification are not straightforward for an average retail investor to fully grasp. Although the KID does not explicitly name 'swaps', 'swaps' are a common type of FDI used for 'direct investment purposes'. Given the strict MiFID II rule provided that 'If any element of ... any Swap usage is identified then the 'classification' must be 'complex'', the integral use of FDIs (which can include swaps) for non-EPM purposes, combined with explicit counterparty risk and the complex nature of the underlying index, collectively leads to a 'complex' classification.'}```",
