        "supporting_data": "The Invesco S&P 500 CTB Net Zero Pathway ESG UCITS ETF is explicitly stated as a UCITS ETF, which benefits from a presumption of non-complexity under MiFID II. It also employs physical replication by holding the underlying securities of its index, which typically supports a non-complex classification. The ETF mentions engaging in securities lending, which is generally considered for efficient portfolio management (EPM) and does not automatically trigger a complex classification, provided it's well-managed and doesn't dominate the risk profile.However, the key factor leading to a complex classification is the nature and transparency of the underlying index, the S&P 500 Climate Transition Base Pathway- Aligned ESG Index. This is not a straightforward, transparent index easily understood by a retail investor with basic knowledge. Its construction involves: (1) multiple exclusionary criteria (e.g., tobacco, controversial weapons, thermal coal, UNGC principles), (2) an 'optimisation approach' to re-weight eligible securities, (3) alignment with EU Climate Transition Benchmarks, (4) alignment to a 1.5u00baC climate scenario using a 'Transition Pathway Model', and (5) an increase in the weighted average S&P Global ESG Score. These elements describe an 'algorithm-based' index construction and re-weighting process, making the ETF's structure and how its payoff is determined opaque and difficult for retail investors to understand, thus overturning the UCITS non-complexity presumption. This aligns with the 'Ease of Understanding' rule and the nuance that complex index transparency can override simple replication. The ESMA Supervisory Briefing (ESMA35-36-1640, point 19) indicates that UCITS with 'algorithm-based payoffs... linked to the performance, or to the realisation of price changes or other conditions, of financial assets, indices or reference portfolios or UCITS with similar features (structured UCITS)' may not be automatically non-complex. The sophisticated methodology of this index falls under 'similar features' to such structured products, making it complex."
