Its primary investment objective is to replicate the MVIS Global Rare Earth/Strategic Metals Index by investing directly in underlying equity securities (physical replication), including stock, ADRs, and GDRs. This replication method typically supports a non-complex classification. However, the Key Investor Information Document explicitly states that the Fund 'may also (or alternatively) invest in financial derivative instruments (FDIs) which relate to the Index or constituents of the Index', and lists 'swaps (equity swaps and swaps on the Index)' among the FDIs it may use. The provided MiFID II rules and ESMA guidance (CESR/09-295, Annex I) clearly categorize instruments involving swaps as complex, stating that 'all derivatives are assumed to be complex because their value is derived from another financial instrument or asset, adding a level of complexity to the understanding of the characteristics and valuation of those instruments.' Furthermore, the specific instruction in the prompt dictates that 'If any element of ... any Swap usage is identified then the classification must be complex'. While the fund primarily uses physical replication and the underlying index itself is not inherently complex (though the sector carries market risks), the explicit mention of the ability to use swaps, even if for efficient portfolio management or optimized sampling, introduces counterparty and collateral risks that are considered difficult for retail investors to understand. Therefore, the presence and potential use of swaps classify this ETF as complex under MiFID II. The fund does not appear to employ significant leverage beyond UCITS limits, nor does it offer capital protection in a complex manner, and it is not an inverse product. Risks identified like emerging markets and smaller companies are market-specific, not structural.'}```",
